Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Intevac, Inc. and its subsidiaries (Intevac or the Company) after elimination of inter-company balances and transactions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Change in Fiscal Year End Date On February 19, 2014, the Board of Directors of the Company approved the Company’s change to a 52-53 week fiscal year ending on the Saturday nearest to December 31 of each year in order to improve the alignment of financial and business processes and to streamline financial reporting. Each fiscal quarter consists of 13 weeks, with an occasional fourth quarter extending to 14 weeks, if necessary, for the fiscal year to end on the Saturday nearest to December 31. The Company’s fiscal 2015 year ended on January 2, 2016. The Company’s fiscal 2014 year ended on January 3, 2015. Cash, Cash Equivalents and Investments Intevac considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Available-for-sale securities, comprised of commercial paper, obligations of the U.S. government and its agencies, corporate debt securities and municipal bonds, are carried at fair value, with unrealized gains and losses recorded within other comprehensive income (loss) as a separate component of stockholders’ equity. Realized gains and losses and declines in value judged to be other than temporary, if any, on available-for-sale securities are included in earnings. Purchases and sales of investment securities are recognized on a trade date basis. The cost of investment securities sold is determined by the specific identification method. Restricted Cash Restricted cash of $1.0 million as of January 2, 2016 secures a standby letter of credit obligation associated with a lease obligation and the restriction on the cash will be removed when the letter of credit expires. In addition Intevac pledged $780,000 as collateral for a banker’s guarantee on an advance payment made by a customer. Derivative Instruments and Hedging Arrangements Foreign Exchange Exposure Management Fair Value Measurement—Definition and Hierarchy Intevac reports certain financial assets and liabilities at fair value. Intevac defines fair value 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. Fair value measurements are classified and disclosed in one of the following three categories: Level 1 Level 2 Level 3 Trade Accounts and Notes Receivables and Doubtful Accounts Intevac evaluates the collectibility of trade accounts receivable and notes receivable on an ongoing basis and provides reserves against potential losses when appropriate. Management analyzes historical bad debts, customer concentrations, customer creditworthiness, changes in customer payment tendencies and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Customer accounts are written off against the allowance when the amount is deemed uncollectible. Also, accounts determined to be uncollectible are put in nonaccrual status whereby interest is not accrued on those accounts. Inventories Inventories are generally stated at the lower of cost or market, with cost determined on an average cost basis. Property, Plant and Equipment Equipment and leasehold improvements are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: computers and software, 3 years; machinery and equipment, 5 years; furniture, 7 years; vehicles, 4 years; and leasehold improvements, remaining lease term. Contingent Consideration and Purchased Intangible Assets Contingent consideration related to a business combination is recorded at the acquisition date at the estimated fair value of the contingent payments. The acquisition date fair value is measured based on the consideration expected to be transferred (probability-weighted), discounted back to present value. The discount rate used is determined at the time of the acquisition in accordance with accepted valuation methods. The fair value of the acquisition-related contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense in the consolidated statements of operations Purchased intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. Purchased intangible assets are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally one to thirteen years using the straight line method. In 2012, as a result of its impairment analysis, Intevac wrote off all of the goodwill in both its Thin-film Equipment and Photonics reporting units. Impairment of Long-Lived Assets Long-lived assets and certain identifiable finite-lived intangible assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability of long-lived assets is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets and certain identifiable intangible assets that management expects to hold and use is based on the fair value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value. No impairment charges were recognized in fiscal 2015, 2014 and 2013. Income Taxes Deferred tax assets and liabilities are recognized using enacted tax rates for the effect of temporary differences between book and tax bases of recorded assets and liabilities. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. On a quarterly basis, Intevac provides for income taxes based upon an annual effective income tax rate. The effective tax rate is highly dependent upon the level of Intevac’s projected earnings, the geographic composition of worldwide earnings, tax regulations governing each region, net operating loss carryforwards, availability of tax credits and the effectiveness of Intevac’s tax planning strategies. Intevac carefully monitors the changes in many factors and adjust its effective income tax rate on a timely basis. If actual results differ from the estimates, this could have a material effect on Intevac’s business, financial condition and results of operations. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with Intevac’s expectations could have a material effect on Intevac’s business, financial condition and results of operations. Intevac recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. Sales and Value Added Taxes Taxes collected from customers and remitted to governmental authorities are presented on a net basis in the accompanying consolidated statements of operations. Revenue Recognition Intevac recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred and title and risk of loss have passed to Intevac’s customer or services have been rendered, the price is fixed or determinable, and collectibility is reasonably assured. Intevac’s shipping terms are customarily FOB shipping point or equivalent terms. Intevac’s revenue recognition policy generally results in revenue recognition at the following points: (1) for all transactions where legal title passes to the customer upon shipment, Intevac recognizes revenue upon shipment for all products that have been demonstrated to meet product specifications prior to shipment; the portion of revenue associated with certain installation-related tasks is deferred, and that revenue is recognized upon completion of the installation-related tasks; (2) for products that have not been demonstrated to meet product specifications prior to shipment, revenue is recognized at customer acceptance; and (3) for arrangements containing multiple elements, the revenue relating to the undelivered elements is deferred until delivery of the deferred elements. When a sales arrangement contains multiple elements, Intevac allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on its VSOE if available, TPE if VSOE is not available, or best ESP if neither VSOE nor TPE is available. Intevac generally utilizes the ESP due to the nature of its products. In certain cases, technology upgrade sales are accounted for as multiple-element arrangements, usually split between delivery of the parts and installation on the customer’s systems. In these cases, Intevac recognizes revenue for the relative sales price of the parts upon shipment and transfer of title, and recognizes revenue for the relative sales price of installation services when those services are completed. Revenue related to sales of spare parts is generally recognized upon shipment. Revenue related to services is generally recognized upon completion of the services. In addition, Intevac uses the installment method to record revenue based on cash receipts in situations where the account receivable is collected over an extended period of time and in management’s judgment the degree of collectibility is uncertain. Intevac performs research and development work under various government-sponsored research contracts. Revenue on cost-plus-fee contracts is recognized to the extent of costs actually incurred plus a proportionate amount of the fee earned. Intevac considers fixed fees under cost-plus-fee contracts to be earned in proportion to the allowable costs actually incurred in performance of the contract. Revenue on fixed-price contracts is recognized on a milestone method or percentage-of-completion method of contract accounting. For contracts structured as milestone agreements, revenue is recognized when a specified milestone is achieved, provided that (1) the milestone event is substantive in nature and there is substantial uncertainty about the achievement of the milestone at the inception of the agreement, (2) the milestone payment is non-refundable, and (3) there is no continuing performance obligations associated with the milestone payment. Any milestone payments received prior to satisfying these revenue recognition criteria are deferred. Intevac generally determines the percentage completed based on the percentage of costs incurred to date in relation to total estimated costs expected through completion of the contract. When estimates of total costs to be incurred on a contract exceed estimates of total revenue to be earned, a provision for the entire loss on the contract is recorded in the period the loss is determined. Advertising Costs Advertising costs are expensed as incurred. Advertising costs were not material for all periods presented. Foreign Currency Translation The functional currency of Intevac’s foreign subsidiaries in Singapore and Hong Kong and the Taiwan branch is the U.S. dollar. The functional currency of Intevac’s foreign subsidiaries in China, Malaysia and Korea is the local currency of the country in which the respective subsidiary operates. Assets and liabilities recorded in foreign currencies are translated at year-end exchange rates; revenues and expenses are translated at average exchange rates during the year. The effect of foreign currency translation adjustments are included in stockholders’ equity as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. The effects of foreign currency transactions are included in other income in the determination of net loss. Net income (losses) from foreign currency transactions were $80,000, $11,000, and $(36,000) in 2015, 2014 and 2013, respectively. Comprehensive Income The changes in accumulated other comprehensive income by component, were as follows for the years ended January 2, 2016 and January 3, 2015: Foreign Unrealized Total (in thousands) Balance at December 31, 2013 $ 691 $ 34 $ 725 Other comprehensive loss before reclassification (71 ) (35 ) (106 ) Amounts reclassified from other comprehensive income — — — Net current-period other comprehensive loss (71 ) (35 ) (106 ) Balance at January 3, 2015 $ 620 $ (1 ) $ 619 Other comprehensive loss before reclassification (168 ) (39 ) (207 ) Amounts reclassified from other comprehensive income — — — Net current-period other comprehensive loss (168 ) (39 ) (207 ) Balance at January 2, 2016 $ 452 $ (40 ) $ 412 Employee Stock Plans Intevac has equity-based compensation plans that provide for the grant to employees of equity-based awards, including incentive or non-statutory stock options, restricted stock, stock appreciation rights, restricted stock units (“RSUs” also referred to as performance units) and performance shares. In addition, these plans provide for the grant of non-statutory stock options and RSUs to non-employee directors and consultants. Intevac also has an employee stock purchase plan, which provides Intevac’s employees with the opportunity to purchase Intevac common stock at a discount through payroll deductions. See Note 2 for a complete description of these plans and their accounting treatment. Recent Accounting Pronouncements In November 2015, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 740, Income Taxes: Balance Sheet Classification of Deferred Taxes. This update simplifies the presentation of current and noncurrent deferred tax liabilities and assets. Under this update, the deferred tax liabilities and assets are classified as noncurrent on the balance sheet. The update does not impact the current requirement that deferred tax liabilities and assets be offset and presented as a single amount. Intevac early adopted this update prospectively in fiscal 2015. The adoption of this update did not have a material impact on our consolidated financial statements. In September 2015, the FASB issued an update to ASC 805, Business Combinations: Simplifying the Accounting Measurement-Period Adjustments. This update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. Under this update, the adjustments are recognized in the reporting period in which the adjustment amounts are determined. This update is effective for Intevac in the first quarter of fiscal 2016 and should be applied prospectively. Intevac does not expect the adoption of this update to have a material impact on its consolidated financial statements. In July 2015, the FASB issued an update to ASC 330, Inventory: Simplifying the Measurement of Inventory. Under this update, subsequent measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and disposal. This update should be applied prospectively and will be adopted by Intevac in the first quarter of fiscal 2017. Early adoption is permitted. Intevac does not expect the adoption of this update to have a material impact on its consolidated financial statements. In April 2015, the FASB issued an update to ASC 350, Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Fees Paid in Cloud Computing Arrangement. This update provides guidance on the accounting for fees paid in a cloud computing arrangement if the arrangement was determined to include a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for as an acquisition of a software license. If the arrangement does not contain a software license, it should be accounted for as a service contract. This update will be effective for Intevac in the first quarter of fiscal 2016 and may be adopted either retrospectively or prospectively. Intevac does not expect the adoption of this update to have a material impact on its consolidated financial statements. In May 2014, the FASB issued an update to ASC 606 Revenue from Contracts with Customers (“ASC 606”) that will supersede virtually all existing revenue guidance. This update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This update to ASC 606 should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. In August 2015, the FASB issued an update to defer the effective date of this update by one year. This update becomes effective and will be adopted by Intevac in the first quarter of fiscal 2018. Early adoption is not permitted for reporting periods before the first quarter of fiscal 2017. The Company is currently evaluating the impact of this update on its consolidated financial statements.

Equity-Based Compensation

Equity-Based Compensation	12 Months Ended
	Jan. 02, 2016
Equity-Based Compensation	2. Equity-Based Compensation Intevac accounts for share-based awards in accordance with the provisions of the accounting guidance which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees, consultants and directors based upon the grant-date fair value of those awards. The estimated fair value of Intevac’s equity-based awards, less expected forfeitures, is amortized over the awards’ service periods using the graded vesting attribution method. Descriptions of Plans Equity Incentive Plans At January 2, 2016, Intevac had equity-based awards outstanding under the 2012 Equity Incentive Plan and the 2004 Equity Incentive Plan (the “Plans”) and the 2003 Employee Stock Purchase Plan (the “ESPP”). Intevac’s stockholders approved all of these plans. The Plans are a broad-based, long-term retention program intended to attract and retain qualified management and employees, and align stockholder and employee interests. The Plans permit the grant of incentive or non-statutory stock options, restricted stock, stock appreciation rights, RSUs and performance shares. Option price, vesting period, and other terms are determined by the administrator of the Plans, but the option price shall generally not be less than 100% of the fair market value per share on the date of grant. As of January 2, 2016, 4.4 million shares of common stock were authorized for future issuance under the Plans. The 2012 Plan expires no later than May 8, 2022. 2003 Employee Stock Purchase Plan In 2003, Intevac’s stockholders approved adoption of the ESPP, which serves as the successor to the Employee Stock Purchase Plan originally adopted in 1995. Upon adoption of the ESPP, all shares available for issuance under the prior plan were transferred to the ESPP. The ESPP provides that eligible employees may purchase Intevac common stock through payroll deductions at a price equal to 85% of the lower of the fair market value at the beginning of the applicable offering period or at the end of each applicable purchase interval. Offering periods are generally two years in length, and consist of a series of six-month purchase intervals. Eligible employees may join the ESPP at the beginning of any six-month purchase interval. Under the terms of the ESPP, employees can choose to have up to 15% of their base earnings withheld to purchase Intevac common stock. As of January 2, 2016, 326,000 shares remained available for issuance under the ESPP. The effect of recording equity-based compensation for fiscal 2015, 2014 and 2013 was as follows (in thousands): 2015 2014 2013 Equity-based compensation by type of award: Stock options $ 963 $ 1,094 $ 984 RSUs 1,711 1,464 419 Employee stock purchase plan 946 442 1,091 Total equity-based compensation $ 3,620 $ 3,000 $ 2,494 Tax effect on equity-based compensation $ — $ — $ 27 Stock Options The exercise price of each stock option equals the market price of Intevac’s stock on the date of grant. Most options are scheduled to vest over three and/or four years and expire no later than ten years after the grant date. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. This model was developed for use in estimating the value of publicly traded options that have no vesting restrictions and are fully transferable. Intevac’s employee stock options have characteristics significantly different from those of publicly traded options. The weighted average assumptions used in the model are outlined in the following table: 2015 2014 2013 Stock Options: Weighted-average fair value of grants per share $ 2.05 $ 3.15 $ 2.49 Expected volatility 46.12 % 52.12 % 56.28 % Risk free interest rate 1.42 % 1.39 % 1.09 % Expected term of options (in years) 3.99 4.38 4.20 Dividend yield None None None The computation of the expected volatility assumption used in the Black-Scholes calculations for new grants is based on historical volatility of Intevac’s stock price. The risk-free interest rate is based on the yield available on U.S. Treasury Strips with an equivalent remaining term. The expected life of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards and vesting schedules. The dividend yield assumption is based on Intevac’s history of not paying dividends and the assumption of not paying dividends in the future. A summary of the stock option activity is as follows: Shares Weighted Weighted Average Aggregate Options outstanding at January 3, 2015 2,584,935 $ 8.26 4.15 $ 1,895,817 Options granted 447,625 $ 5.51 Options cancelled and forfeited (544,423 ) $ 9.67 Options exercised (54,490 ) $ 4.40 Options outstanding at January 2, 2016 2,433,647 $ 7.52 4.10 $ 141,546 Vested and expected to vest at January 2, 2016 2,300,981 $ 7.60 4.01 $ 138,643 Options exercisable at January 2, 2016 1,415,758 $ 8.55 3.17 $ 112,363 The total intrinsic value of options exercised during fiscal years 2015, 2014 and 2013 was $65,000, $496,000 and $49,000, respectively. At January 2, 2016, Intevac had $900,000 of total unrecognized compensation expense, net of estimated forfeitures, related to stock option plans that will be recognized over the weighted average period of 1.15 years. The options outstanding and currently exercisable at January 2, 2016 were in the following exercise price ranges: Options Outstanding Options Exercisable Range of Exercise Prices Number of Outstanding Weighted Weighted Number Weighted $3.91 - $ 5.62 831,947 5.28 $ 4.93 269,411 $ 4.30 $5.71 - $7.55 854,325 4.31 $ 6.93 461,122 $ 6.94 $7.74 - $22.01 747,375 2.55 $ 11.08 685,225 $ 11.32 $3.91 - $22.01 2,433,647 4.10 $ 7.52 1,415,758 $ 8.55 Stock Option Exchange Program During our Annual Stockholder’s Meeting held on May 9, 2013, our stockholders approved a one-time Employee Stock Option Exchange Program (the “Exchange Program”) pursuant to which eligible employees were provided an opportunity to exchange, on a grant-by-grant basis, eligible outstanding stock options for a lesser number of new options, to be granted under our 2012 Equity Incentive Plan. Options eligible for the Exchange Program are those that were granted prior to the 12-month period preceding the start of the Exchange Program offering period, and have exercise prices per share that are greater than $8.49, 50% above our closing per share stock price measured as of July 5, 2013 which is shortly before the start of the Exchange Program. The Exchange Program offering period commenced on July 6, 2013 and closed on August 6, 2013, at which time a total of 87 eligible option holder participants exchanged 766,000 outstanding stock options for 336,000 stock options. The Exchange Program was launched to restore the intended retention and incentive value of employee equity awards, reduce the potential dilutive effect of our equity incentive program, and reduce pressure to grant additional equity awards to employees in the short term. Participation in the Exchange Program was made available to all employees in the United States and Singapore except for the Named Executive Officers. Non-employee members of our Board of Directors were also not eligible to participate. The exchange of options under the Exchange Program resulted in a total incremental charge to compensation expense of $126,000. This incremental charge is being recognized over the vesting periods of the new options. These vesting periods range from one to three years beginning on the first anniversary of the grant. RSUs A summary of the RSU activity is as follows: Shares Weighted Fair Value Weighted Average Aggregate Non-vested RSUs at January 3, 2015 350,429 $ 6.62 1.56 $ 2,586,166 Granted 346,586 $ 6.01 Vested (112,376 ) $ 7.06 Cancelled (31,055 ) $ 6.30 Non-vested RSUs at January 2, 2016 553,584 $ 6.16 1.02 $ 2,607,381 RSUs are converted into shares of Intevac common stock upon vesting on a one-for-one basis. RSUs typically are scheduled to vest over three and/or four years. Vesting of RSUs is subject to the grantee’s continued service with Intevac. The compensation expense related to these awards is determined using the fair market value of Intevac common stock on the date of the grant, and the compensation expense is recognized over the vesting period. At January 2, 2016, Intevac had $991,000 of total unrecognized compensation expense, net of estimated forfeitures, related to RSUs that will be recognized over the weighted average period of 1.02 years. The annual bonus for participants in the Company’s annual incentive plan for fiscal 2015 will be settled with RSUs with one year vesting issued in 2016. The Company accrued for the payment of bonuses at the expected company-wide payout percentage amount at January 2, 2016, which amounts were less than the target bonus amounts for each participant. The bonus accrual is classified as a liability until the number of shares is determined on the date the awards are granted, at which time the Company classifies the awards into equity. The Company recorded equity-based compensation expense related to the annual incentive plan of $324,000 in fiscal 2015. At January 2, 2016, Intevac had $560,000 of total unrecognized compensation expense, net of estimated forfeitures, related to the annual incentive plan that will be recognized over the weighted average period of 0.69 years. The annual bonus for participants in the Company’s annual incentive plan for fiscal 2014 was settled with RSUs with one year vesting issued in 2015. The Company recorded equity-based compensation expense related to the annual incentive plan of $554,000 in fiscal 2014. In February 2015, the annual bonus for certain participants was settled with RSUs with one year vesting. Twenty-nine participants were granted stock awards to receive 133,000 shares of common stock with a weighted average grant date fair value of $6.85 per share. Performance-based RSUs (“performance-based awards”) granted in fiscal 2013 to certain executive officers are also subject to the achievement of specified performance goals. These performance-based awards become eligible to vest only if performance goals are achieved and then actually will vest only if the grantee remains employed by Intevac through each applicable vesting date. The fair value of these performance-based awards is estimated on the date of grant and assumes that the specified performance goals will be achieved. If the goals are achieved, these awards vest over a specified remaining service period, provided that the grantee remains employed by Intevac through each scheduled vesting date. If the performance goals are not met, no compensation expense is recognized and any previously recognized compensation expense is reversed. The expected cost of each award is reflected over the service period and is reduced for estimated forfeitures. For performance-based awards granted during fiscal 2013, the performance goals require the achievement of targeted revenues and adjusted annual operating profit levels measured at the end of two and three-year periods. In early 2015, the Compensation Committee assessed performance against the goals following the completion of the 2-year performance period for Tranche 1 and determined that 5,532 shares of the awards became earned and therefore eligible for time-based vesting. In early 2016, the Compensation Committee assessed performance against the goals following the completion of the 3-year performance period for Tranche 2 and determined that 4,920 shares of the awards became earned and therefore eligible for time-based vesting. ESPP The fair value of the employee stock purchase right is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions: 2015 2014 2013 Stock Purchase Rights: Weighted-average fair value of grants per share $ 2.14 $ 2.08 $ 1.63 Expected volatility 43.45 % 44.00 % 51.54 % Risk free interest rate 0.45 % 0.11 % 0.26 % Expected term of purchase rights (in years) 1.36 0.69 1.77 Dividend yield None None None The expected life of purchase rights is the period of time remaining in the current offering period. The ESPP activity during fiscal 2015, 2014 and 2013 is as follows: 2015 2014 2013 (in thousands, except per share amounts) Shares purchased 374 444 457 Weighted average purchase price per share $ 3.90 $ 3.63 $ 3.58 Aggregate intrinsic value of purchase rights exercised $ 688 $ 1,444 $ 745 As of January 2, 2016, Intevac had $595,000 of total unrecognized compensation expense, net of estimated forfeitures related to purchase rights that will be recognized over the weighted average period of 0.70 years.

Earnings Per Share	3. Earnings Per Share Intevac calculates basic earnings per share (“EPS”) using net income (loss) and the weighted-average number of shares outstanding during the reporting period. Diluted EPS includes the effect from potential issuance of common stock pursuant to the exercise of employee stock options and vesting of RSUs. The following table sets forth the computation of basic and diluted loss per share: 2015 2014 2013 (in thousands, except per share amounts) Net loss $ (9,166 ) $ (27,445 ) $ (15,696 ) Weighted-average shares – basic 22,218 23,671 23,832 Effect of dilutive potential common shares — — — Weighted-average shares – diluted 22,218 23,671 23,832 Net loss per share – basic and diluted $ (0.41 ) $ (1.16 ) $ (0.66 ) As the Company is in a net loss position, all of the Company’s equity instruments are considered antidilutive.

Concentrations	4. Concentrations Credit Risk and Significant Customers Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash equivalents, short- and long-term investments, restricted cash, and accounts receivable. Intevac generally invests its excess cash in money market funds, commercial paper, obligations of the U.S. government and its agencies, corporate debt securities and municipal bonds. The Company has adopted an investment policy and established guidelines relating to credit quality, diversification and maturities of its investments in order to preserve principal and maintain liquidity. All investment securities in Intevac’s portfolio have an investment grade credit rating. Intevac’s accounts receivable tend to be concentrated in a limited number of customers. The following customers accounted for at least 10 percent of Intevac’s accounts receivable at January 2, 2016 and January 3, 2015. 2015 2014 HGST 37 % * Western Digital 15 % * U.S. Government 11 % 13 % Seagate Technology * 46 % * Less than 10% Intevac’s largest customers tend to change from period to period. Historically, a significant portion of Intevac’s revenues in any particular period have been attributable to sales to a limited number of customers. Intevac performs credit evaluations of its customers’ financial condition and generally requires deposits on system orders but does not generally require collateral or other security to support customer receivables. The following customers accounted for at least 10 percent of Intevac’s consolidated net revenues in fiscal 2015, 2014, and/or 2013. 2015 2014 2013 U.S. Government 26 % 32 % * Seagate Technology 22 % 15 % 37 % HGST 15 % 17 % * Northrop Grumman * * 11 % * Less than 10% Products Disk manufacturing products contributed a significant portion of Intevac’s revenues in fiscal 2015, 2014, and 2013. Intevac expects that the ability to maintain or expand its current levels of revenues in the future will depend upon continuing market demand for its products; its success in enhancing its existing systems and developing and manufacturing competitive disk manufacturing equipment, such as the 200 Lean; its success in utilizing Intevac’s expertise in complex manufacturing equipment to develop and sell new equipment products for PV and DCP manufacturing and Intevac’s success in developing military products based on its low-light technology.

Contingent Consideration	7. Contingent Consideration In connection with the acquisition of SIT, Intevac agreed to pay up to an aggregate of $7.0 million in cash to the selling shareholders if certain milestones were achieved over a specified period. Intevac has made payments to the selling shareholders for achievement of the first milestone in 2011, and for achievement of the second and third milestones in 2012. The fourth and final milestone was not achieved on the targeted date outlined in the acquisition agreement and will not be paid. There is no remaining contingent consideration obligation associated with the milestone agreement at January 2, 2016. In connection with the acquisition of SIT, Intevac also agreed to pay to the selling shareholders in cash a revenue earnout on Intevac’s net revenue from commercial sales of certain products over a specified period up to an aggregate of $9.0 million. Intevac estimated the fair value of this contingent consideration on January 2, 2016 based on probability-based forecasted revenues reflecting Intevac’s own assumptions concerning future revenue from such products. As of January 2, 2016, payments made associated with the revenue earnout obligation have not been significant. The fair value measurement of contingent consideration is based on significant inputs not observable in the market and thus represents a Level 3 measurement. The following table represents the quantitative range of the significant unobservable inputs used in the calculation of fair value of the contingent consideration liability as of January 2, 2016. Significant increases or decreases in any of these inputs even in isolation would result in a significantly lower (higher) fair value measurement.

Divestiture Sale of DeltaNu On March 29, 2013, the Company sold certain assets, including existing tangible and intangible assets, which comprised its Raman spectroscopy instruments product line, also known as DeltaNu, for consideration not to exceed $1.5 million. Under the terms of the agreement, the acquirer also assumed certain liabilities related to the purchased assets. Payment terms included $500,000 which was paid on the closing date, with the remaining balance to be paid in the form of an earnout of 5% of the acquirer’s Raman spectroscopy instrument sales for 5 years following the closing date which will be due and payable on or before each anniversary of the closing date or a minimum earnout payment of $100,000 annually, whichever is higher. The maximum earnout payments during the payment period shall not exceed $1.0 million. As the earnout is collected over an extended period of time and in management’s judgment the degree of collectibility is uncertain, Intevac did not recognize the minimum earnout payments upon closing, but instead will record income in the period when the minimum earnout payments can be reasonably estimated for that period and payment is assured. The first and second earnout payments in the amount of $75,000 and $100,000 were received in fiscal 2014 and fiscal 2015 and were reported in other income (expense), net on the consolidated statements of operations.

This investment manager performs a review of the pricing methodologies and inputs utilized by the independent pricing services for each asset type priced by the vendor. In addition, on at least an annual basis, the investment manager conducts due diligence visits and interviews with each pricing vendor to verify the inputs utilized for each asset class. The due diligence visits include a review of the procedures performed by each vendor to ensure that pricing evaluations are representative of the price that would be received to sell a security in an orderly transaction. Any pricing where the input is based solely on a broker price is deemed to be a Level 3 price. Intevac uses the pricing data obtained from its outside investment manager as the primary input to make its assessments and determinations as to the ultimate valuation of the above-mentioned securities and has not made, during the periods presented, any material adjustments to such inputs.

These derivatives are carried at fair value with changes recorded in interest income and other, net in the consolidated statements of operations. Changes in the fair value of these derivatives are largely offset by re-measurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. The derivatives have maturities of approximately 30, 60, 210 and 240 days.

Equity	10. Equity Stock Repurchase Program On November 21, 2013, Intevac’s Board of Directors approved a stock repurchase program authorizing up to $30.0 million in repurchases. Under this authorization, Intevac purchases shares of its common stock under a systematic stock repurchase program and may also make supplemental stock repurchases from time to time, depending on market conditions, stock price and other factors. On November 12, 2015, Intevac entered into a Share Repurchase Agreement with Northern Right Capital Management, L.P. and certain of its affiliated funds, including on behalf of a managed account (collectively, “NRC”), whereby Intevac repurchased 1,483,171 shares of its common stock (or approximately 6.8% of the outstanding common stock) from NRC in a privately negotiated transaction at a purchase price of $4.98 per share, for an aggregate purchase price of $7.4 million. The repurchase was made in conjunction with Intevac’s stock repurchase program. At January 2, 2016, $1.5 million remains available for future stock repurchases under the repurchase program. The following table summarizes Intevac’s stock repurchases for fiscal 2015, 2014 and 2013: 2015 2014 2013 (in thousands, except per share amounts) Shares of common stock repurchased 3,419 1,185 241 Cost of stock repurchased $ 18,503 $ 8,302 $ 1,688 Average price paid per share $ 5.39 $ 6.97 $ 6.97 Intevac records treasury stock purchases under the cost method using the first-in, first-out (FIFO) method. Upon reissuance of treasury stock, amounts in excess of the acquisition cost are credited to additional paid-in capital. If Intevac reissues treasury stock at an amount below its acquisition cost and additional paid-in capital associated with prior treasury stock transactions is insufficient to cover the difference between the acquisition cost and the reissue price, this difference is recorded against retained earnings.

Significant components of deferred tax assets are as follows (in thousands): January 2, January 3, Deferred tax assets: Vacation, warranty and other accruals $ 898 $ 997 Depreciation and amortization 814 538 Intangible amortization 2,397 2,767 Inventory valuation 3,321 3,117 Deferred income 750 1,621 Equity-based compensation 3,612 5,920 Net operating loss, research and other tax credit carryforwards 51,186 47,044 Other 481 358 63,459 62,362 Valuation allowance for deferred tax assets (62,365 ) (60,612 ) Total deferred tax assets 1,094 1,750 Deferred tax liabilities: Purchased technology (950 ) (1,195 ) Unbilled revenue (132 ) (555 ) Other — — Total deferred tax liabilities (1,082 ) (1,750 ) Net deferred tax assets $ 12 $ — As reported on the balance sheet: Current deferred tax assets $ 12 $ — Non-current deferred tax assets — 5 Current deferred tax liability — (5 ) $ 12 $ — Intevac accounts for income taxes in accordance with accounting standards for such taxes, which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the financial reporting and tax bases of recorded assets and liabilities. Accounting standards also require that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion of or all of the deferred tax asset will not be realized. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A significant element of objective negative evidence evaluated was the cumulative loss incurred over the three-year periods ended January 3, 2015, December 31, 2013 and December 31, 2012. Such objective evidence limits the ability to consider other subjective evidence such as Intevac’s projections for future growth. On the basis of this analysis and the significant negative objective evidence, for fiscal 2014, a valuation allowance of $9.4 million was added to record only the portion of the Singapore deferred tax asset that more likely than not will be realized. For fiscal 2015, a valuation allowance increase of $631,000 for the Singapore deferred tax asset was recorded. In fiscal 2012, a valuation allowance of $23.4 million was added to record only the portion of the U.S. federal deferred tax asset that more likely than not will be realized. For fiscal 2015, 2014 and 2013, valuation allowance increases of $1.6 million, $4.7 million and $7.2 million, respectively for the U.S. federal deferred tax asset were recorded. A valuation allowance is recorded against the entire state deferred tax asset which consists of state income tax temporary differences and deferred research and other tax credits that are not realizable in the foreseeable future. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased, or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as our projections for growth. As of January 2, 2016, our federal, foreign and state net operating loss carryforwards for income tax purposes were approximately $56.6 million, $59.8 million and $62.0 million, respectively. The federal and state net operating loss carryforwards are subject to various limitations under Section 382 of the Internal Revenue Code and applicable state tax laws. If not utilized, the federal net operating loss carryforwards will begin to expire in 2028 and the state net operating loss carryforwards will begin to expire in 2016. The foreign net operating loss carryforwards do not expire. As of January 2, 2016, our federal and state tax credit carryforwards for income tax purposes were approximately $12.3 million and $12.8 million, respectively. If not utilized, the federal tax credit carryforwards will begin to expire in 2019 and the state tax credits carry forward indefinitely. The difference between the tax provision (benefit) at the statutory federal income tax rate and the tax provision (benefit) for fiscal 2015, 2014 and 2013 was as follows (in thousands): 2015 2014 2013 Income tax (benefit) at the federal statutory rate $ (3,014 ) $ (6,656 ) $ (6,096 ) State income taxes, net of federal benefit 6 5 12 Change in valuation allowance: U.S 1,625 4,733 7,201 Foreign 631 9,394 — Effect of foreign operations taxed at various rates (140 ) 1,662 983 Research tax credits (931 ) (569 ) (2,284 ) Effect of tax rate changes, permanent differences and adjustments of prior deferrals 2,114 153 (1,062 ) Unrecognized tax benefits 264 (294 ) (476 ) Total $ 555 $ 8,428 $ (1,722 ) Intevac has not provided for U.S. federal income and foreign withholding taxes on approximately $12.8 million of undistributed earnings from non-U.S. operations as of January 2, 2016 because Intevac intends to reinvest such earnings indefinitely outside of the United States. If Intevac were to distribute these earnings, foreign tax credits may become available under current law to reduce the resulting U.S. income tax liability. Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. Intevac will remit the non-indefinitely reinvested earnings, if any, of Intevac’s non-U.S. subsidiaries where excess cash has accumulated and Intevac determines that it is advantageous for business operations, tax or cash reasons. Intevac benefitted from tax incentives in Singapore which were scheduled to expire at the end of 2015. These tax incentives provided a lower income tax rate on certain classes of income so long as certain thresholds of business investment and employment levels were met in Singapore. Intevac was granted an early termination of this tax benefit arrangement effective January 1, 2013 by the Singapore tax authority. The terms of the early termination include meeting certain agreed upon future annual business spending and staffing levels in Singapore. Failure to meet the terms of the early termination could result in a claw back by the Singapore government of tax benefits received in previous years. The total amount of gross unrecognized tax benefits was $7.2 million as of January 2, 2016, of which $354,000 would affect Intevac’s effective tax rate if realized. The aggregate changes in the balance of gross unrecognized tax benefits were as follows for fiscal 2015, 2014 and 2013: 2015 2014 2013 (in thousands) Beginning balance $ 6,578 $ 6,482 $ 6,000 Additions based on tax positions related to the current year 574 57 597 Additions for tax positions of prior years 21 250 98 Settlements — — — Lapse of statute of limitations — (211 ) (213 ) Ending balance $ 7,173 $ 6,578 $ 6,482 The Company does not anticipate any changes in the amount of unrecognized tax benefits in the next twelve months. It is Intevac’s policy to include interest and penalties related to unrecognized tax benefits in the provision for income taxes on the consolidated statements of operations. During fiscal 2015, 2014 and 2013, Intevac recognized a net tax expense (benefit) for interest of $2,000, ($110,000) and ($13,000), respectively. As of January 2, 2016 Intevac had $10,000 of accrued interest related to unrecognized tax benefits, which was classified as a long-term liability in the consolidated balance sheets. Intevac did not accrue any penalties related to these unrecognized tax benefits because Intevac has other tax attributes which would offset any potential taxes due. Intevac is subject to income taxes in the U.S. federal jurisdiction, and various state and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. The material jurisdictions where Intevac is subject to potential examination by tax authorities for tax years after 2009 include the U.S. (Federal and California) and Singapore. The Singapore Inland Revenue Authority is currently conducting a review of the fiscal 2009 through 2012 tax returns of the Company’s wholly-owned subsidiary, Intevac Asia Pte. Ltd. The Singapore Inland Revenue Authority has challenged the Company’s tax position with respect to certain aspects of the Company’s transfer pricing. Under Singapore tax law, the Company must pay all contested taxes and the related interest to have the right to defend its position. As a result, the Company made deposits of $318,000 for the 2009 tax year in fiscal 2014 and $1.1 million for the 2010 tax year in fiscal 2015, respectively. These deposits of $1.4 million are included in other long-term assets at January 2, 2016. The ultimate outcome of this examination is subject to uncertainty, and the Company has a liability for its uncertain tax position in Singapore as of January 2, 2016 of $262,000. The Company’s management and its advisors continue to believe that the Company is “more likely than not” to successfully defend that the tax treatment was proper and in accordance with Singapore tax regulations. Based on the information currently available, the Company does not anticipate a significant increase or decrease to its unrecognized tax benefits for this matter within the next twelve months. We believe that adequate amounts have been reserved for any adjustments that may ultimately result from this or other examinations. Presently, there are no other active income tax examinations in the jurisdictions where Intevac operates.

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended
	Jan. 02, 2016
Employee Benefit Plans	12. Employee Benefit Plans Employee Savings and Retirement Plan In 1991, Intevac established a defined contribution retirement plan with 401(k) plan features. The plan covers all United States employees eighteen years and older. Employees may make contributions by a percentage reduction in their salaries, not to exceed the statutorily prescribed annual limit. Intevac did not make any cash contributions for fiscal 2015 and fiscal 2014. Intevac made cash contributions of $422,000 for fiscal 2013. Employees may choose among several investment options for their contributions and their share of Intevac’s contributions, and they are able to move funds between investment options at any time. Intevac’s common stock is not one of the investment options. Administrative expenses relating to the plan are insignificant. Employee Bonus Plans Intevac has various employee bonus plans. A profit-sharing plan provides for the distribution of a percentage of pre-tax profits to substantially all of Intevac’s employees not eligible for other performance-based incentive plans, up to a maximum percentage of compensation. Other plans award annual cash bonuses to Intevac’s executives and key contributors based on the achievement of profitability and other specific performance criteria. Charges to expense under these plans were $219,000, $22,000 and $1.7 million, respectively for fiscal 2015, 2014 and 2013. In fiscal 2015 and fiscal 2014, the annual bonus for certain participants in the Company’s annual incentive plan will be settled with RSUs with one year vesting. Charges for bonuses in the amount of $324,000 and $554,000 for fiscal 2015 and fiscal 2014 were reported as stock compensation expense. In February 2015, the annual bonus for certain participants of the 2014 annual incentive plan was settled with RSUs with one year vesting. Twenty-nine participants were granted stock awards to receive 133,000 shares of common stock with a weighted average grant date fair value of $6.85 per share. See Note 2 “Equity-Based Compensation.”

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended
	Jan. 02, 2016
Commitments and Contingencies	13. Commitments and Contingencies Leases Intevac leases certain facilities under non-cancelable operating leases that expire at various times up to March 2024 and has options to renew most leases, with rentals to be negotiated. Certain of Intevac’s leases contain provisions for rental adjustments. Included in other long-term liabilities on the consolidated balance sheets is $1.2 of deferred rent as of January 2, 2016 related to the effective rent on Intevac’s long-term lease for Intevac’s Santa Clara, California facility. The terms of the Company’s lease of its Santa Clara, California facility include a tenant improvement allowance of up to $1.7 million. Tenant improvement allowances are reimbursements received from the landlord for construction costs and are amortized on a straight-line basis over the lease term as a reduction in rent. The tenant improvement allowances are recorded when the Company has completed its obligations and the tenant improvement allowance is receivable. In addition, Intevac is required to maintain a standby letter of credit for $1.0 million for this lease. This standby letter of credit is secured with $1.0 million of restricted cash. The facility leases require Intevac to pay for all normal maintenance costs. Gross rental expense was approximately $4.0 million, $3.8 million and $2.9 million for fiscal 2015, 2014, and 2013, respectively. As of January 2, 2016, future minimum lease payments are as follows. (in thousands) 2016 $ 3,108 2017 2,636 2018 2,630 2019 2,709 2020 2,790 Thereafter 9,650 $ 23,523 Guarantees Officer and Director Indemnifications As permitted or required under Delaware law and to the maximum extent allowable under that law, Intevac has certain obligations to indemnify its current and former officers and directors for certain events or occurrences while the officer or director is, or was serving, at Intevac’s request in such capacity. These indemnification obligations are valid as long as the director or officer acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The maximum potential amount of future payments Intevac could be required to make under these indemnification obligations is unlimited; however, Intevac has a director and officer insurance policy that mitigates Intevac’s exposure and enables Intevac to recover a portion of any future amounts paid. As a result of Intevac’s insurance policy coverage, Intevac believes the estimated fair value of these indemnification obligations is not material. Other Indemnifications As is customary in Intevac’s industry, many of Intevac’s contracts provide remedies to certain third parties such as defense, settlement, or payment of judgment for intellectual property claims related to the use of its products. Such indemnification obligations may not be subject to maximum loss clauses. Historically, payments made related to these indemnifications have been immaterial. Letters of Credit As of January 2, 2016, we had letters of credit and bank guarantees outstanding totaling $1.8 million, including the standby letter of credit outstanding under the Santa Clara, California facility lease and a banker’s guarantee which guarantees customer advances under a customer contract. These letters of credit and bank guarantees are collateralized by $1.8 million of restricted cash. Warranty Intevac provides for the estimated cost of warranty when revenue is recognized. Intevac’s warranty is per contract terms and for its disk manufacturing, PV manufacturing and DCP manufacturing systems the warranty typically ranges between 12 and 24 months from customer acceptance. For systems sold through a distributor, Intevac offers a 3 month warranty. The remainder of any warranty period is the responsibility of the distributor. During this warranty period any defective non-consumable parts are replaced and installed at no charge to the customer. The warranty period on consumable parts is limited to their reasonable usable lives. Intevac uses estimated repair or replacement costs along with its historical warranty experience to determine its warranty obligation. Intevac generally provides a twelve month warranty on its Photonics’ products. The provision for the estimated future costs of warranty is based upon historical cost and product performance experience. Intevac exercises judgment in determining the underlying estimates. On the consolidated balance sheets, the short-term portion of the warranty provision is included in other accrued liabilities, while the long-term portion is included in other long-term liabilities. The expense associated with product warranties issued or adjusted is included in cost of net revenues on the consolidated statements of operations. The following table displays the activity in the warranty provision account for fiscal 2015 and 2014: 2015 2014 (in thousands) Beginning balance $ 1,186 $ 1,647 Expenditures incurred under warranties (463 ) (834 ) Accruals for product warranties 837 931 Adjustments to previously existing warranty accruals (578 ) (558 ) Ending balance $ 982 $ 1,186 Legal Matters From time to time, Intevac receives notification from third parties, including customers and suppliers, seeking indemnification, litigation support, payment of money or other actions in connection with claims made against them. In addition, from time to time, Intevac receives notification from third parties claiming that Intevac may be or is infringing their intellectual property or other rights. Intevac also is subject to various other legal proceedings and claims, both asserted and unasserted, that arise in the ordinary course of business. Although the outcome of these claims and proceedings cannot be predicted with certainty, Intevac does not believe that any of these other existing proceedings or claims will have a material adverse effect on its consolidated financial condition or results of operations.

Segment and Geographic Informat

Segment and Geographic Information	12 Months Ended
	Jan. 02, 2016
Segment and Geographic Information	14. Segment and Geographic Information Intevac’s two reportable segments are: Thin-film Equipment and Photonics. Intevac’s chief operating decision-maker has been identified as the President and CEO, who reviews operating results to make decisions about allocating resources and assessing performance for the entire Company. Segment information is presented based upon Intevac’s management organization structure as of January 2, 2016 and the distinctive nature of each segment. Future changes to this internal financial structure may result in changes to the reportable segments disclosed. Each reportable segment is separately managed and has separate financial results that are reviewed by Intevac’s chief operating decision-maker. Each reportable segment contains closely related products that are unique to the particular segment. Segment operating profit is determined based upon internal performance measures used by the chief operating decision-maker. Intevac derives the segment results from its internal management reporting system. The accounting policies Intevac uses to derive reportable segment results are substantially the same as those used for external reporting purposes. Management measures the performance of each reportable segment based upon several metrics, including orders, net revenues and operating income. Management uses these results to evaluate the performance of, and to assign resources to, each of the reportable segments. Intevac manages certain operating expenses separately at the corporate level. Intevac allocates certain of these corporate expenses to the segments in an amount equal to 3% of net revenues. Segment operating income excludes interest income/expense and other financial charges and income taxes according to how a particular reportable segment’s management is measured. Management does not consider impairment charges, gains and losses on divestitures and sales of intellectual property, and unallocated costs in measuring the performance of the reportable segments. The Thin-film Equipment segment designs, develops and markets vacuum process equipment solutions for high-volume manufacturing of small substrates with precise thin-film properties, such as for the hard drive, solar cell and DCP industries, as well as other adjacent thin-film markets. The Photonics segment develops compact, cost-effective, high-sensitivity digital-optical products for the capture and display of low-light images. Intevac provides sensors, cameras and systems for government applications such as night vision and long-range target identification.

Restructuring Charges	15. Restructuring Charges During the first quarter of fiscal 2015, Intevac substantially completed implementation of the 2015 cost reduction plan (the “2015 Plan”), which was intended to reduce expenses and reduce its workforce by 3 percent. The cost of implementing the 2015 Plan was reported under cost of net revenues and operating expenses in the consolidated statements of operations. Substantially all cash outlays in connection with the 2015 Plan occurred in the first quarter of fiscal 2015. Implementation of the 2015 Plan is expected to reduce salary, wages and other employee-related expenses by approximately $1.4 million on an annual basis. During the first half of fiscal 2014, Intevac substantially completed implementation of the 2014 cost reduction plan (the “2014 Plan”), which was intended to reduce expenses and reduce its workforce by 6 percent. The cost of implementing the 2014 Plan was reported under cost of net revenues and operating expenses in the consolidated statements of operations. Substantially all cash outlays in connection with the 2014 Plan occurred in the first half of fiscal 2014. Implementation of the 2014 Plan reduced salary, wages and other employee-related expenses by approximately $2.1 million on an annual basis. On February 1, 2013, Intevac announced the 2013 cost reduction plan (the “2013 Plan”) to reduce expenses including a reduction in its workforce. Implementation of the 2013 Plan was substantially completed in the first half of fiscal 2013 and the Company reduced its workforce by 18 percent. The cost of implementing the 2013 Plan was reported under cost of net revenues and operating expenses in the consolidated statement of operations. Substantially all cash outlays in connection with the 2013 Plan occurred in the first half of fiscal 2013. As of January 2, 2016, activities related to the 2015, 2014 and 2013 Plans were complete.

Summary of Significant Accoun25

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 02, 2016
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Intevac, Inc. and its subsidiaries (Intevac or the Company) after elimination of inter-company balances and transactions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
Change in Fiscal Year End-Date	Change in Fiscal Year End Date On February 19, 2014, the Board of Directors of the Company approved the Company’s change to a 52-53 week fiscal year ending on the Saturday nearest to December 31 of each year in order to improve the alignment of financial and business processes and to streamline financial reporting. Each fiscal quarter consists of 13 weeks, with an occasional fourth quarter extending to 14 weeks, if necessary, for the fiscal year to end on the Saturday nearest to December 31. The Company’s fiscal 2015 year ended on January 2, 2016. The Company’s fiscal 2014 year ended on January 3, 2015.
Cash, Cash Equivalents and Investments	Cash, Cash Equivalents and Investments Intevac considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Available-for-sale securities, comprised of commercial paper, obligations of the U.S. government and its agencies, corporate debt securities and municipal bonds, are carried at fair value, with unrealized gains and losses recorded within other comprehensive income (loss) as a separate component of stockholders’ equity. Realized gains and losses and declines in value judged to be other than temporary, if any, on available-for-sale securities are included in earnings. Purchases and sales of investment securities are recognized on a trade date basis. The cost of investment securities sold is determined by the specific identification method.
Restricted Cash	Restricted Cash Restricted cash of $1.0 million as of January 2, 2016 secures a standby letter of credit obligation associated with a lease obligation and the restriction on the cash will be removed when the letter of credit expires. In addition Intevac pledged $780,000 as collateral for a banker’s guarantee on an advance payment made by a customer.
Derivative Instruments and Hedging Arrangements	Derivative Instruments and Hedging Arrangements Foreign Exchange Exposure Management
Fair Value Measurement-Definition and Hierarchy	Fair Value Measurement—Definition and Hierarchy Intevac reports certain financial assets and liabilities at fair value. Intevac defines fair value 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. Fair value measurements are classified and disclosed in one of the following three categories: Level 1 Level 2 Level 3
Trade Accounts and Notes Receivables and Doubtful Accounts	Trade Accounts and Notes Receivables and Doubtful Accounts Intevac evaluates the collectibility of trade accounts receivable and notes receivable on an ongoing basis and provides reserves against potential losses when appropriate. Management analyzes historical bad debts, customer concentrations, customer creditworthiness, changes in customer payment tendencies and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Customer accounts are written off against the allowance when the amount is deemed uncollectible. Also, accounts determined to be uncollectible are put in nonaccrual status whereby interest is not accrued on those accounts.
Inventories	Inventories Inventories are generally stated at the lower of cost or market, with cost determined on an average cost basis.
Property, Plant and Equipment	Property, Plant and Equipment Equipment and leasehold improvements are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: computers and software, 3 years; machinery and equipment, 5 years; furniture, 7 years; vehicles, 4 years; and leasehold improvements, remaining lease term.
Contingent Consideration and Purchased Intangible Assets	Contingent Consideration and Purchased Intangible Assets Contingent consideration related to a business combination is recorded at the acquisition date at the estimated fair value of the contingent payments. The acquisition date fair value is measured based on the consideration expected to be transferred (probability-weighted), discounted back to present value. The discount rate used is determined at the time of the acquisition in accordance with accepted valuation methods. The fair value of the acquisition-related contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense in the consolidated statements of operations Purchased intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. Purchased intangible assets are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally one to thirteen years using the straight line method. In 2012, as a result of its impairment analysis, Intevac wrote off all of the goodwill in both its Thin-film Equipment and Photonics reporting units.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets and certain identifiable finite-lived intangible assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability of long-lived assets is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets and certain identifiable intangible assets that management expects to hold and use is based on the fair value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value. No impairment charges were recognized in fiscal 2015, 2014 and 2013.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized using enacted tax rates for the effect of temporary differences between book and tax bases of recorded assets and liabilities. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. On a quarterly basis, Intevac provides for income taxes based upon an annual effective income tax rate. The effective tax rate is highly dependent upon the level of Intevac’s projected earnings, the geographic composition of worldwide earnings, tax regulations governing each region, net operating loss carryforwards, availability of tax credits and the effectiveness of Intevac’s tax planning strategies. Intevac carefully monitors the changes in many factors and adjust its effective income tax rate on a timely basis. If actual results differ from the estimates, this could have a material effect on Intevac’s business, financial condition and results of operations. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with Intevac’s expectations could have a material effect on Intevac’s business, financial condition and results of operations. Intevac recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes.
Sales and Value Added Taxes	Sales and Value Added Taxes Taxes collected from customers and remitted to governmental authorities are presented on a net basis in the accompanying consolidated statements of operations.
Revenue Recognition	Revenue Recognition Intevac recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred and title and risk of loss have passed to Intevac’s customer or services have been rendered, the price is fixed or determinable, and collectibility is reasonably assured. Intevac’s shipping terms are customarily FOB shipping point or equivalent terms. Intevac’s revenue recognition policy generally results in revenue recognition at the following points: (1) for all transactions where legal title passes to the customer upon shipment, Intevac recognizes revenue upon shipment for all products that have been demonstrated to meet product specifications prior to shipment; the portion of revenue associated with certain installation-related tasks is deferred, and that revenue is recognized upon completion of the installation-related tasks; (2) for products that have not been demonstrated to meet product specifications prior to shipment, revenue is recognized at customer acceptance; and (3) for arrangements containing multiple elements, the revenue relating to the undelivered elements is deferred until delivery of the deferred elements. When a sales arrangement contains multiple elements, Intevac allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on its VSOE if available, TPE if VSOE is not available, or best ESP if neither VSOE nor TPE is available. Intevac generally utilizes the ESP due to the nature of its products. In certain cases, technology upgrade sales are accounted for as multiple-element arrangements, usually split between delivery of the parts and installation on the customer’s systems. In these cases, Intevac recognizes revenue for the relative sales price of the parts upon shipment and transfer of title, and recognizes revenue for the relative sales price of installation services when those services are completed. Revenue related to sales of spare parts is generally recognized upon shipment. Revenue related to services is generally recognized upon completion of the services. In addition, Intevac uses the installment method to record revenue based on cash receipts in situations where the account receivable is collected over an extended period of time and in management’s judgment the degree of collectibility is uncertain. Intevac performs research and development work under various government-sponsored research contracts. Revenue on cost-plus-fee contracts is recognized to the extent of costs actually incurred plus a proportionate amount of the fee earned. Intevac considers fixed fees under cost-plus-fee contracts to be earned in proportion to the allowable costs actually incurred in performance of the contract. Revenue on fixed-price contracts is recognized on a milestone method or percentage-of-completion method of contract accounting. For contracts structured as milestone agreements, revenue is recognized when a specified milestone is achieved, provided that (1) the milestone event is substantive in nature and there is substantial uncertainty about the achievement of the milestone at the inception of the agreement, (2) the milestone payment is non-refundable, and (3) there is no continuing performance obligations associated with the milestone payment. Any milestone payments received prior to satisfying these revenue recognition criteria are deferred. Intevac generally determines the percentage completed based on the percentage of costs incurred to date in relation to total estimated costs expected through completion of the contract. When estimates of total costs to be incurred on a contract exceed estimates of total revenue to be earned, a provision for the entire loss on the contract is recorded in the period the loss is determined.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. Advertising costs were not material for all periods presented.
Foreign Currency Translation	Foreign Currency Translation The functional currency of Intevac’s foreign subsidiaries in Singapore and Hong Kong and the Taiwan branch is the U.S. dollar. The functional currency of Intevac’s foreign subsidiaries in China, Malaysia and Korea is the local currency of the country in which the respective subsidiary operates. Assets and liabilities recorded in foreign currencies are translated at year-end exchange rates; revenues and expenses are translated at average exchange rates during the year. The effect of foreign currency translation adjustments are included in stockholders’ equity as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. The effects of foreign currency transactions are included in other income in the determination of net loss. Net income (losses) from foreign currency transactions were $80,000, $11,000, and $(36,000) in 2015, 2014 and 2013, respectively.
Comprehensive Income	Comprehensive Income The changes in accumulated other comprehensive income by component, were as follows for the years ended January 2, 2016 and January 3, 2015: Foreign Unrealized Total (in thousands) Balance at December 31, 2013 $ 691 $ 34 $ 725 Other comprehensive loss before reclassification (71 ) (35 ) (106 ) Amounts reclassified from other comprehensive income — — — Net current-period other comprehensive loss (71 ) (35 ) (106 ) Balance at January 3, 2015 $ 620 $ (1 ) $ 619 Other comprehensive loss before reclassification (168 ) (39 ) (207 ) Amounts reclassified from other comprehensive income — — — Net current-period other comprehensive loss (168 ) (39 ) (207 ) Balance at January 2, 2016 $ 452 $ (40 ) $ 412
Employee Stock Plans	Employee Stock Plans Intevac has equity-based compensation plans that provide for the grant to employees of equity-based awards, including incentive or non-statutory stock options, restricted stock, stock appreciation rights, restricted stock units (“RSUs” also referred to as performance units) and performance shares. In addition, these plans provide for the grant of non-statutory stock options and RSUs to non-employee directors and consultants. Intevac also has an employee stock purchase plan, which provides Intevac’s employees with the opportunity to purchase Intevac common stock at a discount through payroll deductions. See Note 2 for a complete description of these plans and their accounting treatment.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2015, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 740, Income Taxes: Balance Sheet Classification of Deferred Taxes. This update simplifies the presentation of current and noncurrent deferred tax liabilities and assets. Under this update, the deferred tax liabilities and assets are classified as noncurrent on the balance sheet. The update does not impact the current requirement that deferred tax liabilities and assets be offset and presented as a single amount. Intevac early adopted this update prospectively in fiscal 2015. The adoption of this update did not have a material impact on our consolidated financial statements. In September 2015, the FASB issued an update to ASC 805, Business Combinations: Simplifying the Accounting Measurement-Period Adjustments. This update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. Under this update, the adjustments are recognized in the reporting period in which the adjustment amounts are determined. This update is effective for Intevac in the first quarter of fiscal 2016 and should be applied prospectively. Intevac does not expect the adoption of this update to have a material impact on its consolidated financial statements. In July 2015, the FASB issued an update to ASC 330, Inventory: Simplifying the Measurement of Inventory. Under this update, subsequent measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and disposal. This update should be applied prospectively and will be adopted by Intevac in the first quarter of fiscal 2017. Early adoption is permitted. Intevac does not expect the adoption of this update to have a material impact on its consolidated financial statements. In April 2015, the FASB issued an update to ASC 350, Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Fees Paid in Cloud Computing Arrangement. This update provides guidance on the accounting for fees paid in a cloud computing arrangement if the arrangement was determined to include a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for as an acquisition of a software license. If the arrangement does not contain a software license, it should be accounted for as a service contract. This update will be effective for Intevac in the first quarter of fiscal 2016 and may be adopted either retrospectively or prospectively. Intevac does not expect the adoption of this update to have a material impact on its consolidated financial statements. In May 2014, the FASB issued an update to ASC 606 Revenue from Contracts with Customers (“ASC 606”) that will supersede virtually all existing revenue guidance. This update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This update to ASC 606 should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. In August 2015, the FASB issued an update to defer the effective date of this update by one year. This update becomes effective and will be adopted by Intevac in the first quarter of fiscal 2018. Early adoption is not permitted for reporting periods before the first quarter of fiscal 2017. The Company is currently evaluating the impact of this update on its consolidated financial statements.
