Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	1. Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements (“condensed consolidated financial statements”) include the accounts of Electronics For Imaging, Inc. and its subsidiaries (“EFI” or “Company”). All intercompany accounts and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP” or “GAAP”) for interim financial information, rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements, and accounting policies consistent in all material respects with those applied in preparing our audited annual consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015. These condensed consolidated financial statements and accompanying notes should be read in conjunction with our annual consolidated financial statements and the notes thereto for the year ended December 31, 2015, included in our Annual Report on Form 10-K. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments, management considers necessary for the fair presentation of our financial position, operating results, comprehensive income, and cash flows for the interim periods presented. Our results for the interim periods are not necessarily indicative of results for the entire year. Recent Accounting Pronouncements Debt Issuance Costs. Measurement Period Adjustments. Inventory Valuation. Stock-based Compensation. • Under the new guidance, all excess tax benefits and deficiencies are recognized as income tax expense. Excess tax benefits of less than $0.1 million that were charged to additional paid-in capital in the first quarter of 2016 were reversed upon adoption. We recorded $2.2 million of deferred tax assets related to excess tax benefits for federal research and development income tax credits not previously benefitted. • The requirement to reclassify gross excess tax benefits related to stock-based compensation from operating to financing activities in the statement of cash flows is eliminated. The reclassification of $0.2 million in the first quarter of 2016 has been reversed upon adoption. We applied this guidance retrospectively to all prior periods to maintain the comparability of presentation between periods, which resulted in a $0.3 million increase in cash flows provided by operating activities during the nine months ended September 30, 2015, and a corresponding decrease in cash flows provided by financing activities. • We have elected to account for forfeitures when they occur instead of estimating the expected forfeiture rate. Adoption of this provision during the second quarter resulted in a retroactive net income adjustment of $0.2 million, net of tax effect, in the first quarter of 2016 and a cumulative effect adjustment to retained earnings of $2.1 million, net of tax, as of January 1, 2016. • Statutory tax withholding will be permitted up to the maximum statutory tax rate in applicable jurisdictions. The retrospective impact of this provision on prior period financial statements is not material. Financial Instruments. ASU 2016-13 will be effective in the first quarter of 2020. We are evaluating its impact on the carrying value of our available-for-sale securities and results of operations. Revenue Recognition. The guidance requires comprehensive annual and interim disclosures regarding the nature, amount, timing, and uncertainty of recognized revenue. Qualitative and quantitative disclosures will be required regarding: • contracts with customers, including revenue and impairments recognized, disaggregation, and information about contract balances and performance obligations, • significant judgments and changes in judgments required to determine the transaction price, amounts allocated to performance obligations, and the timing for recognizing revenue resulting from the satisfaction of performance obligations, and • assets recognized from the costs to obtain or fulfill a contract. The guidance will be effective in the first quarter of 2018. We are evaluating its impact on our revenue and results of operations. Principal vs Agent. A number of indicators of the nature of the relationship that are considered under current guidance have been streamlined and clarified in the new guidance by focusing more specifically on the performance obligations that must be fulfilled in the transaction, which entity carries the inventory risk in the transaction, and which entity controls the pricing of the good or service. Credit risk will no longer be a criterion. This guidance will be effective in the first quarter of 2018. We are evaluating its impact on our revenue and results of operations. Lease Arrangements. The recognition, measurement, and presentation of expenses and cash flows by a lessee have not significantly changed from previous guidance. There continues to be a differentiation between finance leases and operating leases. The criteria for determining whether a lease is a financing or operating lease are substantially the same as existing guidance except that the “bright line” percentages have been removed. • For finance leases, interest is recognized on the lease liability separately from depreciation of the right-of-use asset in the statement of operations. Principal repayments are classified within financing activities and interest payments are classified as operating activities in the statement of cash flows. • For operating leases, a lessee is required to recognize lease expense generally on a straight-line basis. All operating lease payments are classified as operating activities in the statement of cash flows. The current build-to-suit lease accounting guidance will be rescinded by the new guidance, although simplified guidance will remain regarding lessee control during the construction period. Consequently, the accounting for build-to-suit leases will be the same as finance leases unless the lessee control provisions are applicable. Settlement of Convertible Debt. ASU 2016-15 will be effective in the first quarter of 2018. Accordingly, $63.6 million debt discount attributable to the difference between the 0.75% coupon interest rate on our Notes and the 4.98% (5.46% inclusive of debt issuance costs) effective interest rate will be classified as an operating cash outflow in the Condensed Consolidated Statement of Cash Flows upon cash settlement in 2019.

Earnings Per Share

Earnings Per Share	9 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	2. Earnings Per Share Net income per basic common share is computed using the weighted average number of common shares outstanding during the period. Net income per diluted common share is computed using the weighted average number of common and dilutive potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect using the treasury stock method, non-vested shares of restricted stock having a dilutive effect, non-vested restricted stock for which the performance criteria have been met, shares to be purchased under our Employee Stock Purchase Plan (“ESPP”) having a dilutive effect, the assumed release of shares from escrow related to the acquisition of Corrugated Technologies, Inc. (“CTI”), the assumed conversion of our Notes having a dilutive effect using the treasury stock method when the stock price exceeds the conversion price of the Notes, and the assumed exercise of our warrants having a dilutive effect using the treasury stock method when the stock price exceeds the warrant strike price. Any potential shares that are anti-dilutive as defined in Accounting Standards Codification (“ASC”) 260, Earnings Per Share, are excluded from the effect of dilutive securities. Performance-based and market-based restricted stock and stock options that would be issuable if the end of the reporting period were the end of the vesting period, if the result would be dilutive, are assumed to be outstanding for purposes of determining net income per diluted common share as of the later of the beginning of the period or the grant date in accordance with ASC 260-10-45-48. Accordingly, performance-based RSUs, which vested on various dates during the three and nine months ended September 30, 2016 and 2015, based on achievement of specified performance criteria related to revenue and non-GAAP operating income targets, and performance-based stock options, which vested during the nine months ended September 30, 2016 based on achievement of specified targets related to non-GAAP return on equity are included in the determination of net income per diluted common share as of the beginning of each period. Basic and diluted earnings per share during the three and nine months ended September 30, 2016 and 2015 are reconciled as follows (in thousands, except per share amounts): Three months ended September 30, Nine months ended September 30, 2016 2015 2016 2015 Basic net income per share: Net income available to common shareholders $ 17,662 $ 10,257 $ 25,000 $ 23,211 Weighted average common shares outstanding 46,794 47,473 46,983 47,104 Basic net income per share $ 0.38 $ 0.22 $ 0.53 $ 0.49 Dilutive net income per share: Net income available to common shareholders $ 17,662 $ 10,257 $ 25,000 $ 23,211 Weighted average common shares outstanding 46,794 47,473 46,983 47,104 Dilutive stock options and non-vested restricted stock 826 1,028 808 1,057 Weighted average common shares outstanding for purposes of computing diluted net income per share 47,621 48,501 47,791 48,161 Dilutive net income per share $ 0.37 $ 0.21 $ 0.52 $ 0.48 Potential shares of common stock that are not included in the determination of diluted net income per share because they are anti-dilutive consist of ESPP purchase rights having an anti-dilutive effect of less than 0.1 million shares for the three and nine months ended September 30, 2016 and 2015 and the assumed vesting of RSUs having an anti-dilutive effect of less than 0.1 million shares for the three and nine months ended September 30, 2016 and less than 0.1 million shares for the nine months ended September 30, 2015. The weighted-average number of common shares outstanding does not include the effect of the potential common shares from conversion of our Notes and exercise of our Warrants. The effects of these potentially outstanding shares were not included in the calculation of diluted net income per share because the effect would have been anti-dilutive since the conversion price of the Notes and the strike price of the warrants exceeded the average market price of our common stock. We have the option to pay cash, issue shares of common stock, or any combination thereof for the aggregate amount due upon conversion of the Notes. Our intent is to settle the principal amount of the Notes in cash upon conversion. As a result, only amounts payable in excess of the principal amount of the Notes are considered in diluted net income per share under the treasury stock method. The Note Hedges are also not included in the calculation of diluted net income per share because the effect of any exercise of the Note Hedges would be anti-dilutive. Please refer to Note 6 – Convertible Senior Notes, Note Hedges, and Warrants of the Notes to Condensed Consolidated Financial Statements for additional information.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions We acquired Optitex Ltd. (“Optitex”) and Rialco Limited (“Rialco”) during 2016, which have been included in our Productivity Software and Industrial Inkjet operating segments, respectively. Acquisition-related transaction costs were $0.4 and $1.7 million during the three and nine months ended September 30, 2016, respectively, and $1.6 and $4.2 million during the three and nine months ended September 30, 2015, respectively. These acquisitions were accounted for as purchase business combinations. We allocated the purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed on the basis of their estimated fair value on their respective acquisition dates. Excess purchase consideration was recorded as goodwill. Factors contributing to a purchase price that results in goodwill include, but are not limited to, the retention of research and development personnel with skills to develop future technology, support personnel to provide maintenance services related to the products, a trained sales force capable of selling current and future products, the opportunity to cross-sell products of the acquired businesses to existing customers, the positive reputation of Optitex and Rialco in the market, and the opportunity to expand our presence in the digital inkjet textile printing market through the synergy of Optitex technology with the Reggiani Macchine SpA (“Reggiani”) digital inkjet textile printer business. Rialco’s technical and commercial capabilities benefit the Industrial Inkjet operating segment in the sourcing, specification, and purification of high quality dyes and expand our research, development, and innovation base to develop ink for the signage, ceramic, and packaging markets. We engaged a third party valuation firm to aid management in its analyses of the fair value of these acquired businesses. All estimates, key assumptions, and forecasts were either provided by or reviewed by us. While we chose to utilize a third party valuation firm, the fair value analyses and related valuations represent the conclusions of management and not the conclusions or statements of any third party. The purchase price allocations are preliminary and subject to change within the respective measurement periods as the valuations are finalized. We expect to continue to obtain information to assist us in finalizing the fair value of the net assets acquired during the respective measurement periods, which end at various dates in 2017. Measurement period adjustments will be recognized in the reporting period in which the adjustment amounts are determined, if any. Productivity Software Segment Optitex, a privately-held Israeli company headquartered in Rosh Ha’Ayin, Israel, was acquired on June 16, 2016. Optitex has been included in the Productivity Software operating segment. We purchased Optitex for cash consideration of $11.6 million, net of cash acquired, plus an additional potential future cash earnout, which is contingent on achieving certain revenue and operating profit performance targets over three consecutive 12-month periods. Optitex has developed and markets integrated two-dimensional (“2D”) and three-dimensional (“3D”) design software that is shortening the design cycle, reducing our customers’ costs, and accelerating the adoption of fast fashion. The fair value of the earnout related to the Optitex acquisition is currently estimated to be $24.0 million by applying the income approach in accordance with ASC 805-30-25-5, Business Combinations, adjusted for the impact of post-acquisition foreign currency translation changes. Key assumptions include a risk-free discount rate of 2.3% and probability-adjusted revenue and operating profit levels. Probability-adjusted revenue and operating profit are significant inputs that are not observable in the market, which are referred to as Level 3 inputs in ASC 820-10-35, Fair Value Measurement. This contingent liability is reflected in the Condensed Consolidated Balance Sheet as of September 30, 2016, as a noncurrent liability with the first payment due in the fourth quarter of 2017, if earned. In accordance with ASC 805-30-35-1, changes in the fair value of contingent consideration subsequent to the acquisition date are recognized in general and administrative expenses Industrial Inkjet Operating Segment Rialco, a private limited liability company incorporated in England and Wales and headquartered in Bradford, U.K., was acquired on March 1, 2016. Rialco has been included in the Industrial Inkjet operating segment. We purchased Rialco for cash consideration of $8.4 million, net of cash acquired, plus an additional potential future cash earnout, which is contingent on achieving certain revenue and gross profit performance targets over three consecutive 12-month periods. Rialco is a leading European supplier of dye powders and color products for the textile, digital print, and other decorating industries. Rialco’s pure disperse dyes are particularly important in the manufacture of high-quality dye sublimation inkjet inks for textile applications, which is a key growth area in the global migration from analog to digital print. The fair value of the earnout related to the Rialco acquisition is currently estimated to be $2.0 million by applying the income approach in accordance with ASC 805-30-25-5, adjusted for the impact of post-acquisition foreign currency translation changes. Key assumptions include a risk-free discount rate of 0.8% and probability-adjusted revenue and gross profit levels. Probability-adjusted revenue and gross profit are significant inputs that are not observable in the market, which ASC 820-10-35, refers to as Level 3 inputs. This contingent liability is reflected in the Condensed Consolidated Balance Sheet as of September 30, 2016, as a current and noncurrent liability of $0.8 and $1.2 million, respectively, with the first payment due in the third quarter of 2017, if earned. In accordance with ASC 805-30-35-1, changes in the fair value of contingent consideration subsequent to the acquisition date are recognized in general and administrative expenses. Valuation Methodologies Intangible assets acquired consist of customer relationships, customer backlog, trade names, existing technology, and in-process research & development (“IPR&D”). Customer Relationships and Backlog Customer backlog represents unfulfilled customer purchase orders at the acquisition date that will provide a relatively secure revenue stream, subject only to potential customer cancellation and discount rates of 23% and 19% for Optitex and Rialco, respectively. These backlogs are expected to be fulfilled within one year. Trade Names Existing Technology Rialco existing technology was valued using the cost approach. The value of existing technology is estimated based on the historical time and cost to develop the technology, the estimated man-years required to recreate the technology, historical employee compensation and benefits, and a reasonable mark-up based on profit for companies with similar operations. The preliminary allocation of the purchase price to the assets acquired and liabilities assumed (in thousands) with respect to these acquisitions at their respective acquisition dates is summarized as follows: Optitex Rialco Weighted average useful life Purchase Weighted average useful life Purchase Customer relationships 3-6 years $ 8,890 5 years $ 2,512 Existing technology 4 years 7,760 5 years 846 Trade names 4 years 2,020 4 years 763 Backlog less than one year 370 less than one year 56 Goodwill — 28,147 — 1,426 $ 47,187 5,603 Net tangible liabilities (11,924 ) 5,177 Total purchase price $ 35,263 $ 10,780 Pro forma results of operations for Optitex and Rialco have not been presented because their pre-acquisition revenue and net income are not material to our Condensed Consolidated Results of Operations for the three and nine months ended September 30, 2016 and 2015. Goodwill, which represents the excess of the purchase price over the net tangible and intangible assets acquired, that was generated by our acquisition of Rialco is not deductible for tax purposes. Goodwill that was generated by our acquisition of Optitex is deductible for U.S. tax purposes, but is not deductible for tax purposes in Israel. Rialco generates revenue and incurs operating expenses primarily in British pounds sterling. Upon consideration of the salient economic indicators discussed in ASC 830-10-55-5, Foreign Currency Matters, we consider the British pounds sterling to be the functional currency for Rialco. Optitex generates revenue and incurs operating expenses primarily in local currencies. Upon consideration of the salient economic indicators, we consider the local currency in each of Optitex’s primary locations (shekel, rupee, Euro, and U.S. dollar) to be the functional currencies for Optitex.

Investments and Fair Value Measurements	5. Investments and Fair Value Measurements We invest our excess cash on deposit with major banks in money market, U.S. Treasury and government-sponsored entity, corporate, asset-backed, and mortgage-backed residential debt securities. By policy, we invest primarily in high-grade marketable securities. We are exposed to credit risk in the event of default by the financial institutions or issuers of these investments to the extent of amounts recorded in our Condensed Consolidated Balance Sheets. We consider all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. Typically, the cost of these investments has approximated fair value. Marketable investments with a maturity greater than three months are classified as available-for-sale short-term investments. Available-for-sale securities are stated at fair value with unrealized gains and losses reported as a separate component of OCI, adjusted for deferred income taxes. The credit portion of any other-than-temporary impairment is included in net income. Realized gains and losses on sales of financial instruments are recognized upon sale of the investments using the specific identification method. Our available-for-sale short-term investments as of September 30, 2016 and December 31, 2015 are as follows (in thousands): Amortized cost Gross Gross Fair value September 30, 2016 U.S. government and sponsored entities $ 76,150 $ 232 $ (44 ) $ 76,338 Corporate debt securities 199,444 496 (148 ) 199,792 Asset-backed securities 27,887 150 (10 ) 28,027 Mortgage-backed securities – residential 1,984 6 (3 ) 1,987 Total short-term investments $ 305,465 $ 884 $ (205 ) $ 306,144 December 31, 2015 U.S. government and sponsored entities $ 98,411 $ 12 $ (137 ) $ 98,286 Corporate debt securities 198,498 20 (510 ) 198,008 Asset-backed securities 35,276 195 (174 ) 35,297 Mortgage-backed securities – residential 1,689 2 (6 ) 1,685 Total short-term investments $ 333,874 $ 229 $ (827 ) $ 333,276 The fair value and duration that investments, including cash equivalents, have been in a gross unrealized loss position as of September 30, 2016 and December 31, 2015 are as follows (in thousands): Less than 12 Months More than 12 Months TOTAL Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized September 30, 2016 U.S. government and sponsored entities $ 41,474 $ (44 ) $ — $ — $ 41,474 $ (44 ) Corporate debt securities 59,274 (70 ) 23,079 (78 ) 82,353 (148 ) Asset-backed securities 214 — 5,627 (10 ) 5,841 (10 ) Mortgage-backed securities – residential 235 — 208 (3 ) 443 (3 ) Total $ 101,197 $ (114 ) $ 28,914 $ (91 ) $ 130,111 $ (205 ) December 31, 2015 U.S. government and sponsored entities $ 82,366 $ (137 ) $ — $ — $ 82,366 $ (137 ) Corporate debt securities 136,274 (448 ) 16,940 (62 ) 153,214 (510 ) Asset-backed securities 27,928 (103 ) 7,131 (71 ) 35,059 (174 ) Mortgage-backed securities – residential 764 (2 ) 269 (4 ) 1,033 (6 ) Total $ 247,332 $ (690 ) $ 24,340 $ (137 ) $ 271,672 $ (827 ) For fixed income securities that have unrealized losses as of September 30, 2016, we have determined that we do not have the intent to sell any of these investments and it is not more likely than not that we will be required to sell any of these investments before recovery of the entire amortized cost basis. We have evaluated these fixed income securities and determined that no credit losses exist. Accordingly, management has determined that the unrealized losses on our fixed income securities as of September 30, 2016 were temporary in nature. Amortized cost and estimated fair value of investments as of September 30, 2016 are summarized by maturity date as follows (in thousands): Amortized cost Fair value Mature in less than one year $ 107,936 $ 107,888 Mature in one to three years 197,529 198,256 Total short-term investments $ 305,465 $ 306,144 Net realized gains of $0.1 and $0.3 million from sales of investments were recognized in interest income and other income (expense), net, during the three and nine months ended September 30, 2016, respectively. Net realized gains of less than $0.1 million from sales of investments were recognized in interest income and other income (expense), net, during the three and nine months ended September 30, 2015. Net unrealized gains of $0.7 million and net unrealized losses of $0.6 million, respectively, were included in OCI in the accompanying Condensed Consolidated Balance Sheets as of September 30, 2016 and December 31, 2015, respectively. Fair Value Measurements ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy as follows: Level 1: Inputs that are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; Level 2: Inputs that are other than quoted prices included within Level 1, that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date for the duration of the instrument’s anticipated life or by comparison to similar instruments; and Level 3: Inputs that are unobservable or reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. These include management’s own judgments about market participant assumptions developed based on the best information available in the circumstances. We utilize the market approach to measure the fair value of our fixed income securities. The market approach is a valuation technique that uses the 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. The fair value of our investments in certain money market funds is expected to maintain a Net Asset Value of $1 per share and, as such, is priced 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. As part of this process, we engaged a pricing service to assist management in its pricing analysis and assessment of other-than-temporary impairment. All estimates, key assumptions, and forecasts were either provided by or reviewed by us. While we chose to utilize a third party pricing service, the impairment analysis and related valuations represent conclusions of management and not conclusions or statements of any third party. Our investments and liabilities measured at fair value have been presented in accordance with the fair value hierarchy specified in ASC 820 as of September 30, 2016 and December 31, 2015 in order of liquidity as follows (in thousands): Total Quoted Prices Significant Unobservable September 30, 2016 Assets: Money market funds $ 15,742 $ 15,742 $ — $ — U.S. government and sponsored entities 76,338 53,483 22,855 — Corporate debt securities 200,027 — 200,027 — Asset-backed securities 28,027 — 27,956 71 Mortgage-backed securities – residential 1,987 — 1,987 — $ 322,121 $ 69,225 $ 252,825 $ 71 Liabilities: Contingent consideration, current and noncurrent $ 85,396 $ — $ — $ 85,396 Self-insurance 598 — — 598 $ 85,994 $ — $ — $ 85,994 December 31, 2015 Assets: Money market funds $ 13,221 $ 13,221 $ — $ — U.S. government and sponsored entities 98,286 34,712 63,574 — Corporate debt securities 198,778 — 198,778 — Asset-backed securities 35,297 — 35,113 184 Mortgage-backed securities – residential 1,684 — 1,684 — $ 347,266 $ 47,933 $ 299,149 $ 184 Liabilities: Contingent consideration, current and noncurrent $ 54,796 $ — $ — $ 54,796 Self-insurance 1,268 — — 1,268 $ 56,064 $ — $ — $ 56,064 Money market funds consist of $15.7 and $13.2 million, which have been classified as cash equivalents as of September 30, 2016 and December 31, 2015, respectively. Corporate debt securities include $0.2 and $0.7 million, which have been classified as cash equivalents as of September 30, 2016 and December 31, 2015, respectively. Investments are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices or alternative pricing sources with reasonable levels of price transparency. Investments in U.S. Treasury obligations and overnight money market mutual funds have been classified as Level 1 because these securities are valued based on quoted prices in active markets or are actively traded at $1.00 Net Asset Value. There have been no transfers between Level 1 and 2 during the nine months ended September 30, 2016 and 2015. Government agency investments and corporate debt instruments, including investments in asset-backed and mortgage-backed securities, have generally been classified as Level 2 because markets for these securities are less active or valuations for such securities utilize significant inputs, which are directly or indirectly observable. We hold asset-backed securities with income payments derived from and collateralized by a specified pool of underlying assets. Asset-backed securities in the portfolio are predominantly collateralized by credit cards and auto loans. We also hold two asset-backed securities collateralized by mortgage loans, which have been fully reserved. Liabilities for Contingent Consideration Acquisition-related liabilities for contingent consideration (i.e., earnouts) are related to the purchase business combinations of Optitex and Rialco in 2016; Shuttleworth Business Systems Limited and CDM Solutions Limited (collectively, “Shuttleworth”), CTI, and Reggiani in 2015; DiMS! organizing print BV (“DIMS”), DirectSmile GmbH (“DirectSmile”), and SmartLinc, Inc. (“SmartLinc”) in 2014; Outback Software Pty. Ltd. doing business as Metrix Software (“Metrix”), GamSys Software SPRL (“GamSys”), and PrintLeader Software (“PrintLeader”) in 2013; and Technique, Inc. and Technique Business Systems Limited (collectively, “Technique”) in 2012. The fair value of these earnouts is estimated to be $85.4 and $54.8 million as of September 30, 2016 and December 31, 2015, respectively, by applying the income approach in accordance with ASC 805-30-25-5. Key assumptions include risk-free discount rates between 0.6% and 4.98% (Monte Carlo valuation method) and discount rates between 4.2% and 6.0% (probability-adjusted method), as well as probability-adjusted revenue, gross profit, operating profit, and earnings before interest and taxes (“EBIT”) levels. Probability-adjusted revenue, gross profit, operating profit, and EBIT are significant inputs that are not observable in the market, which ASC 820-10-35 refers to as Level 3 inputs. These contingent liabilities have been reflected in the Condensed Consolidated Balance Sheet as of September 30, 2016 as current and noncurrent liabilities of $30.3 and $55.1 million, respectively. The fair value of contingent consideration increased by $6.3 million, including $1.9 million of earnout interest accretion related to all acquisitions, during the nine months ended September 30, 2016. The Optitex, Reggiani, DirectSmile, and CTI earnout performance probabilities increased while the DIMS earnout performance probability decreased during the nine months ended September 30, 2016. The fair value of contingent consideration decreased by $2.1 million, which is net of $1.4 million of earnout interest accretion related to all acquisitions, during the year ended December 31, 2015. The DIMS, DirectSmile, GamSys, and Metrix earnout performance probabilities decreased in 2015. In accordance with ASC 805-30-35-1, changes in the fair value of contingent consideration subsequent to the acquisition date have been recognized in general and administrative expense. Earnout payments during the nine months ended September 30, 2016 of $1.2, $0.4, and $0.2 million are primarily related to the previously accrued DirectSmile, SmartLinc, and Metrix contingent consideration liabilities, respectively. Earnout payments during the year ended December 31, 2015 of $2.0, $1.1, $0.6, and $0.3 million are primarily related to the previously accrued Technique, GamSys, Metrix, and SmartLinc contingent consideration liabilities, respectively. Changes in the fair value of contingent consideration are summarized as follows (in thousands): Liability for Contingent Consideration Fair value of contingent consideration at January 1, 2015 $ 12,277 Fair value of Reggiani contingent consideration at July 1, 2015 43,170 Fair value of CTI contingent consideration at October 6, 2015 2,551 Fair value of Shuttleworth contingent consideration at November 4, 2015 5,077 Changes in valuation (3,575 ) Payments (4,093 ) Foreign currency adjustment (611 ) Fair value of contingent consideration at December 31, 2015 $ 54,796 Fair value of Rialco contingent consideration at March 1, 2016 $ 2,109 Fair value of Optitex contingent consideration at June 16, 2016 22,300 Changes in valuation 6,308 Payments (1,868 ) Foreign currency adjustment 1,751 Fair value of contingent consideration at September 30, 2016 $ 85,396 Since the primary inputs to the fair value measurement of contingent consideration liability are the discount rate and probability-adjusted revenue, we reviewed the sensitivity of the fair value measurement to changes in these inputs. We assessed the probability of achieving the revenue performance targets for contingent consideration associated with each acquisition at percentage levels between 60% and 100% as of each respective acquisition date based on an assessment of the historical performance of each acquired entity, our current expectations of future performance, and other relevant factors. A change in probability-adjusted revenue of five percentage points from the level assumed in the current valuations would result in an increase in the fair value of contingent consideration of $2.7 million or a decrease of $6.2 million resulting in a corresponding adjustment to general and administrative expense. A change in the discount rate of one percentage point results in an increase in the fair value of contingent consideration of $0.3 million or a decrease of $1.9 million. The potential undiscounted amount of future contingent consideration cash payments that we could be required to make related to our business acquisitions, beyond amounts currently accrued, is $23.3 million as of September 30, 2016. Fair Value of Derivative Instruments We utilize the income approach to measure the fair value of our derivative assets and liabilities. The income approach uses pricing models that rely on market observable inputs such as yield curves, currency exchange rates, and forward prices, and are therefore classified as Level 2 measurements. The notional amount of our derivative assets and liabilities was $156.8 and $118.6 million as of September 30, 2016 and December 31, 2015, respectively. The fair value of our derivative assets and liabilities that were designated for cash flow hedge accounting treatment having notional amounts of $3.2 and $3.2 million as of September 30, 2016 and December 31, 2015, respectively, was not material. Fair Value of Convertible Senior Notes In September 2014, we issued $345 million aggregate principal amount of our Notes. The Notes are carried at their original issuance value, net of unamortized debt discount, and are not marked to market each period. The approximate fair value of the Notes as of September 30, 2016 was approximately $383 million and was considered a Level 2 fair value measurement. Fair value was estimated based upon actual quotations obtained at the end of the reporting period or the most recent date available. A substantial portion of the market value of our Notes in excess of the outstanding principal amount relates to the conversion premium.

Convertible Senior Notes ("Notes"), Note Hedges, and Warrants	6. Convertible Senior Notes (“Notes”), Note Hedges, and Warrants 0.75% Convertible Senior Notes Due 2019 In September 2014, we completed a private placement of $345 million principal amount of 0.75% Convertible Senior Notes due 2019 (“Notes”). The Notes were sold to the initial purchasers for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The net proceeds from this offering were approximately $336.3 million, after deducting the initial purchasers’ commissions and the offering expenses paid by us. We used approximately $29.4 million of the net proceeds to purchase the Note Hedges described below, net of the proceeds from the Warrant transactions also described below. The Notes are senior unsecured obligations of EFI with interest payable semiannually in arrears on March 1 and September 1 of each year, commencing March 1, 2015. The Notes are not callable and will mature on September 1, 2019, unless previously purchased or converted in accordance with their terms prior to such date. Holders of the Notes who convert in connection with a “fundamental change,” as defined in the indenture governing the Notes (“Indenture”), may require us to purchase for cash all or any portion of their Notes at a purchase price equal to 100 percent of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any. The initial conversion rate is 18.9667 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $52.72 per share of common stock. Upon conversion of the Notes, holders will receive cash, shares of common stock or a combination thereof, at our election. Our intent is to settle the principal amount of the Notes in cash upon conversion. If the conversion value exceeds the principal amount, we would deliver shares of our common stock for our conversion obligation in excess of the aggregate principal amount. As of September 30, 2016, none of the conditions listed below allowing holders of the Notes to convert had been met. Throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a Note. Holders may convert their Notes only under the following circumstances: • if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; • during the five business day period after any five consecutive trading day period (“Notes Measurement Period”) in which the “trading price” (as the term is defined in the Indenture) per $1,000 principal amount of Notes for each trading day of such Notes Measurement Period was less than 98% of the product of the last reported stock price on such trading day and the conversion rate on each such trading day; • upon the occurrence of specified corporate events; or • at any time on or after March 1, 2019 until the close of business on the second scheduled trading day immediately preceding the maturity date. We separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the estimated fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Notes as a whole. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense over the term of the Notes using the effective interest method with an effective interest rate of 4.98% per annum (5.46% inclusive of debt issuance costs). The equity component is not remeasured as long as it continues to meet the conditions for equity classification. We allocated the total transaction costs incurred by the Note issuance to the liability and equity components based on their relative values. Issuance costs of $7.0 million attributable to the $281.4 million liability component are being amortized to expense over the term of the Notes, and issuance costs of $1.6 million attributable to the $63.6 million equity component were offset against the equity component in stockholders’ equity. Additionally, we recorded a deferred tax liability of $23.7 million on the debt discount, which is not deductible for tax purposes. The Notes consist of the following as of September 30, 2016 and December 31, 2015 (in thousands): September 30, December 31, 2016 2015 Liability component $ 345,000 $ 345,000 Debt discount, net of amortization (39,363 ) (48,515 ) Debt issuance costs, net of amortization (4,660 ) (5,751 ) Net carrying amount $ 300,977 $ 290,734 Equity component $ 63,643 $ 63,643 Less: debt issuance costs allocated to equity (1,582 ) (1,582 ) Net carrying amount $ 62,061 $ 62,061 Upon adoption of ASU 2015-03, $5.8 million of debt issuance costs have been reclassified from other current assets and other assets to a direct reduction of convertible senior notes, net, in our Condensed Consolidated Balance Sheet as of December 31, 2015. Interest expense recognized related to the Notes during the three and nine months ended September 30, 2016 and 2015 was as follows (in thousands): Three months ended Nine months ended September 30, September 30, 2016 2015 2016 2015 0.75% coupon $ 654 $ 654 $ 1,941 $ 1,948 Amortization of debt issuance costs 373 354 1,092 1,042 Amortization of debt discount 3,126 2,961 9,152 8,698 $ 4,153 $ 3,969 $ 12,185 $ 11,688 Note Hedges We paid an aggregate of $63.9 million in convertible note hedge transactions with respect to our common stock (“Note Hedges”) in September 2014. The Note Hedges will expire upon maturity of the Notes. The Note Hedges are intended to offset the potential dilution upon conversion and/or offset any cash payments we are required to make in excess of the principal amount upon conversion of the Notes in the event that the market value per share of our common stock, as measured under the terms of the Note Hedges, is greater than the strike price of the Note Hedges. The strike price of the Note Hedges initially correspond to the conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion price of the Notes. The Note Hedges are separate transactions and are not part of the Notes. Holders of the Notes will not have any rights with respect to the Note Hedges. Warrants Concurrently with entering into the Note Hedges, we separately entered into warrant transactions (“Warrants”), whereby we sold warrants to acquire shares of our common stock at a strike price of $68.86 per share. We received aggregate proceeds of $34.5 million from the sale of the Warrants. If the average market value per share of our common stock for the reporting period, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on our earnings per share. The Warrants are separate transactions and are not part of the Notes or the Note Hedges and are accounted for as a component of additional paid-in capital. Holders of the Notes and Note Hedges will not have any rights with respect to the Warrants.

Income taxes	7. Income taxes We recognized tax benefits of $11.8 and $9.0 million on pretax net income of $5.8 and $15.9 million during the three and nine months ended September 30, 2016, respectively. We recognized a tax benefit of $2.8 million and a tax provision of $0.1 million on pretax net income of $7.5 and $23.3 million during the three and nine months ended September 30, 2015, respectively. The provisions for income taxes before discrete items reflected in the table below were $3.3 and $6.1 million during the three and nine months ended September 30, 2016, respectively, and $3.5 and $7.6 million during the three and nine months ended September 30, 2015, respectively. The decrease in the provision for income taxes before discrete items for the three and nine months ended September 30, 2016, compared with the same periods in the prior year, is primarily due to the decrease in profitability before income taxes. Primary differences between our provision for income taxes before discrete items and the income tax provision at the U.S. statutory rate of 35% include lower taxes on permanently reinvested foreign earnings and the tax effects of stock-based compensation expense pursuant to ASC 718-740, Stock Compensation – Income Taxes, which are non-deductible for tax purposes. Our tax provision before discrete items is reconciled to our recorded provision for income taxes during the three and nine months ended September 30, 2016 and 2015 as follows (in millions): Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Provision for income taxes before discrete items $ 3.3 $ 3.5 $ 6.1 $ 7.6 Interest related to unrecognized tax benefits — 0.1 0.3 0.3 Benefit related to U.S. transfer pricing adjustment — — — (0.4 ) Benefit related to Spanish statutory and tax intangibles write-off — — — (0.3 ) Benefit related to stock based compensation, including ESPP dispositions (1.4 ) (0.2 ) (1.7 ) (0.4 ) Benefit from reassessment of tax provision upon filing tax return (0.2 ) (1.8 ) (0.2 ) (1.8 ) Benefit from reversals of uncertain tax positions due to statute of limitation expirations (13.5 ) (4.4 ) (13.5 ) (4.9 ) Provision for (benefit from) income taxes $ (11.8 ) $ (2.8 ) $ (9.0 ) $ 0.1 As of September 30, 2016 and December 31, 2015, gross unrecognized benefits that would affect the effective tax rate if recognized were $35.8 and $43.5 million, respectively. Over the next twelve months, our existing tax positions will continue to generate increased liabilities for unrecognized tax benefits. It is reasonably possible that our gross unrecognized tax benefits will decrease up to $4.8 million in the next twelve months primarily due to the lapse of the statute of limitations for federal and state tax purposes. These adjustments, if recognized, would positively impact our effective tax rate, and would be recognized as additional tax benefits in our Condensed Consolidated Statements of Operations. In accordance with ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, Similar Tax Loss, or Tax Credit Carryforward Exists, we recorded $23.5 million of gross unrecognized tax benefits as an offset to deferred tax assets as of September 30, 2016, and the remaining $12.3 million has been recorded as noncurrent income taxes payable. We recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of September 30, 2016 and December 31, 2015, we have accrued $0.8 and $0.5 million, respectively, for potential payments of interest and penalties. In accordance with ASU 2016-09, which was adopted in the second quarter of 2016, we recorded $2.2 million of deferred tax assets related to excess tax benefits for federal research and development income tax credits not previously benefitted and $0.6 million of deferred tax assets for the tax benefit on the cumulative effect adjustment associated with the change in accounting for RSU forfeitures. We are subject to examination by the Internal Revenue Service (“IRS”) for the 2013-2015 tax years, state tax jurisdictions for the 2011-2015 tax years, the Netherlands tax authority for the 2014-2015 tax years, the Spanish tax authority for the 2012-2015 tax years, and the Italian tax authority for the 2012-2015 tax years.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Contingent Consideration We are required to make payments to the former stockholders of acquired companies based on the achievement of specified performance targets as more fully explained in Note 5 – Investments and Fair Value Measurements. Lease Commitments and Contractual Obligations As of September 30, 2016, we have leased certain of our current facilities under noncancellable operating lease agreements. We are required to pay property taxes, insurance, and nominal maintenance costs for certain of these facilities and any increases over the base year of these expenses on the remainder of our facilities. Assets Held for Sale Management has approved a plan to sell approximately 5.6 acres of land and the office building located at 1340 Corporate Center Curve, Eagan, Minnesota, consisting of 43,682 square feet. We intend to enter into a lease agreement with the purchaser of the facility whereby we will lease 22,000 square feet under a ten-year lease agreement at market rental rates. The gain on the sale of the facility and land will be deferred over the lease term. Assets held for sale of $3.8 million have been reclassified to Other Current Assets as of September 30, 2016 consisting of $2.9 million net book value of the facility and $0.9 million of related land. Management expects the sale and related lease-back to be completed in the next nine months. Off-Balance Sheet Financing - Synthetic Lease Arrangements On August 26, 2016, we entered into a 48.5 year lease agreement, inclusive of two renewal options, with the City of Manchester to lease 16.9 acres adjacent to the Manchester Regional Airport. This lease agreement is subject to a sublease agreement with Bank of Tokyo – Mitsubishi UFJ Leasing & Finance LLC (“BTMU”) during the term of the synthetic lease related to the manufacturing facility that is being constructed on the site. Minimum lease payments are $13.1 million during the 48.5 year term, excluding the portion financed into the synthetic lease related to the manufacturing facility. We are treated as the owner of the construction project for federal income tax purposes. On August 26, 2016, we entered into a six-year synthetic lease with BTMU whereby a 225,000 square foot manufacturing and warehouse facility is under construction related to our super-wide format industrial digital inkjet printer business in the Industrial Inkjet operating segment at a projected cost of $40 million and a construction period of 18 months. Minimum lease payments during the initial term are $1.8 million. Upon completion of the initial term, we have the option to renew the lease, purchase the facility, or return the facility to BTMU subject to an 89% residual value guarantee under which we would recognize additional rent expense in the form of a variable rent payment. We have assessed our exposure in relation to the residual value guarantee and believe that there is no deficiency to the guaranteed value with respect to funds expended by BTMU as of September 30, 2016. The funds pledged under the lease represent 115% of the total expenditures made by BTMU through September 30, 2016. The funds are invested in $3.1 and $0.7 million of U.S. government securities and cash equivalents, respectively, with a third party trustee and will be restricted during the construction period. Upon completion of construction, the funds will be released as cash and cash equivalents. The portion of released funds that represents 100% of the total expenditures made by BTMU will be deposited with BTMU and restricted as collateral until the end of the underlying synthetic lease period. The funds pledged as collateral are invested in U.S. government securities and cash equivalents as of September 30, 2016, and are classified as Level 1 in the fair value hierarchy as more fully defined in Note 5—Investments and Fair Value Measurements. Net unrealized gains of less than $0.1 million were included in OCI in the accompanying Condensed Consolidated Balance Sheet as of September 30, 2016. We have applied the accounting and disclosure requirements set forth in ASC 810-10, Consolidation, for variable interest entities (“VIEs”). We have evaluated the synthetic lease agreement to determine if the arrangement qualifies as a VIE under ASC 810-10. We have determined that the synthetic lease agreement does not qualify as a VIE, and as such, we are not required to consolidate the VIE in our condensed consolidated financial statements. Legal Proceedings We may be involved, from time to time, in a variety of claims, lawsuits, investigations, or proceedings relating to contractual disputes, securities laws, intellectual property rights, employment, or other matters that may arise in the normal course of business. We assess our potential liability in each of these matters by using the information available to us. We develop our views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and various combinations of appropriate litigation and settlement strategies. We accrue estimated losses from contingencies if a loss is deemed probable and can be reasonably estimated. As of September 30, 2016, we are subject to the matter discussed below. Matan Digital Printing (“MDG”) Matter EFI acquired Matan Digital Printers (“Matan”) in 2015 from sellers (the “2015 Sellers”) that acquired Matan Digital Printing Ltd. from other sellers in 2001 (the “2001 Sellers”). The 2001 Sellers have asserted a claim against the 2015 Sellers and Matan asserting that they are entitled to a portion of the 2015 Sellers’ proceeds from EFI’s acquisition. The 2015 Sellers dispute this claim and have agreed to indemnify EFI against the 2001 Sellers’ claim. Although we are fully indemnified and we do not believe that it is probable that we will incur a loss, it is reasonably possible that our financial statements could be materially affected by the unfavorable resolution of this matter. Accordingly, it is reasonably possible that we could incur a material loss in this matter. We estimate the range of loss to be between one dollar and $9.6 million. If we incur a loss in this matter, it will be offset by a receivable of an equal amount representing a claim for indemnification against the escrow account established in connection with the Matan acquisition. Other Matters As of September 30, 2016, we were subject to various other claims, lawsuits, investigations, and proceedings in addition to the matter discussed above. There is at least a reasonable possibility that additional losses may be incurred in excess of the amounts that we have accrued. However, we believe that these claims are not material to our financial statements or the range of reasonably possible losses is not reasonably estimable. Litigation is inherently unpredictable, and while we believe that we have valid defenses with respect to legal matters pending against us, our financial statements could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies or because of the diversion of management’s attention and the incurrence of significant expenses.

Segment Reporting [Abstract]
Segment Information and Geographic Data	9. Segment Information and Geographic Data Operating segment information is required to be presented based on the internal reporting used by the chief operating decision making group (“CODM”) to allocate resources and evaluate operating segment performance. Our CODM is comprised of our Chief Executive Officer and Chief Financial Officer. The CODM group is focused on assessment and resource allocation among the Industrial Inkjet, Productivity Software, and Fiery operating segments. Our operating segments are integrated through their reporting and operating structures, shared technology and practices, shared sales and marketing, and combined production facilities. Our enterprise management processes use financial information that is closely aligned with our three operating segments at the gross profit level. Relevant discrete financial information is prepared at the gross profit level for each of our three operating segments, which is used by the CODM to allocate resources and assess the performance of each operating segment. We classify our revenue, operating segment profit (i.e., gross profit), assets, and liabilities in accordance with our operating segments as follows: Industrial Inkjet, Productivity Software, Productivity Suite Packaging Suite, Corrugated Packaging Suite, Enterprise Commercial Print Suite, Publication Print Suite, Mid-market Print Suite, Quick Print Suite, Value Added Products, Fiery, Our CODM evaluates the performance of our operating segments based on net sales and gross profit. Gross profit for each operating segment includes revenue from sales to third parties and related cost of revenue attributable to the operating segment. Cost of revenue for each operating segment excludes certain expenses managed outside the operating segments consisting primarily of stock-based compensation expense. Operating income is not reported by operating segment because operating expenses include significant shared expenses and other costs that are managed outside of the operating segments. Such operating expenses include various corporate expenses such as stock-based compensation, corporate sales and marketing, research and development, amortization of identified intangibles, various non-recurring charges, and other separately managed general and administrative expenses. Operating segment profit (i.e., gross profit), excluding stock-based compensation expense, during the three and nine months ended September 30, 2016 and 2015 is summarized as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Industrial Inkjet Revenue $ 143,004 $ 122,566 $ 408,926 $ 305,815 Gross profit 50,433 42,428 141,927 104,863 Gross profit percentages 35.3 % 34.6 % 34.7 % 34.3 % Productivity Software Revenue $ 39,663 $ 31,706 $ 108,554 $ 96,497 Gross profit 30,041 23,142 80,961 70,173 Gross profit percentages 75.7 % 73.0 % 74.6 % 72.7 % Fiery Revenue $ 62,908 $ 74,422 $ 207,878 $ 223,657 Gross profit 45,362 51,500 147,938 157,562 Gross profit percentages 72.1 % 69.2 % 71.2 % 70.4 % Operating segment profit (i.e., gross profit) is reconciled to our Condensed Consolidated Statements of Operations during the three and nine months ended September 30, 2016 and 2015 as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Segment gross profit $ 125,836 $ 117,070 $ 370,826 $ 332,598 Stock-based compensation expense (642 ) (785 ) (1,873 ) (2,357 ) Other items excluded from segment profit — — (315 ) (113 ) Gross profit $ 125,194 $ 116,285 $ 368,638 $ 330,128 Tangible and intangible assets, net of liabilities, are summarized by operating segment as follows (in thousands): September 30, 2016 Industrial Productivity Fiery Corporate and Total Goodwill $ 146,657 $ 158,716 $ 63,624 $ — $ 368,997 Identified intangible assets, net 89,432 42,937 108 — 132,477 Tangible assets, net of liabilities 151,132 (36,941 ) 32,974 181,934 329,099 Net tangible and intangible assets $ 387,221 $ 164,712 $ 96,706 $ 181,934 $ 830,573 December 31, 2015 Goodwill $ 142,183 $ 133,128 $ 63,482 $ — $ 338,793 Identified intangible assets, net 101,623 33,432 497 — 135,552 Tangible assets, net of liabilities 102,351 (10,023 ) 23,954 233,567 349,849 Net tangible and intangible assets $ 346,157 $ 156,537 $ 87,933 $ 233,567 $ 824,194 Corporate and unallocated assets consist of cash and cash equivalents, short-term investments, restricted investments, corporate headquarters facility, convertible notes, imputed financing obligation, taxes receivable, and taxes payable. Geographic Regions Our revenue originates in the U.S., China, the Netherlands, Germany, Italy, France, the U.K., Spain, Israel, Brazil, Australia, and New Zealand. We report revenue by geographic region based on ship-to destination. Shipments to some of our significant printer manufacturer/distributor customers are made to centralized purchasing and manufacturing locations, which in turn sell through to other locations. As a result of these factors, we believe that sales to certain geographic locations might be higher or lower, as the ultimate destinations are difficult to ascertain. Our revenue by ship-to destination during the three and nine months ended September 30, 2016 and 2015 was as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Americas $ 128,252 $ 121,116 $ 363,977 $ 337,050 Europe, Middle East, and Africa (“EMEA”) 85,009 79,934 264,469 205,191 Asia Pacific (“APAC”) 32,314 27,644 96,912 83,728 Total revenue $ 245,575 $ 228,694 $ 725,358 $ 625,969

Derivatives and Hedging

Derivatives and Hedging	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	10. Derivatives and Hedging We are exposed to market risk and foreign currency exchange risk from changes in foreign currency exchange rates, which could affect operating results, financial position, and cash flows. We manage our exposure to these risks through our regular operating and financing activities and, when appropriate, through the use of derivative financial instruments. These derivative financial instruments are used to hedge monetary assets and liabilities, intercompany balances, trade receivables, anticipated cash flows, and to reduce earnings and cash flow volatility resulting from shifts in market rates. Our objective is to offset gains and losses resulting from these exposures with losses and gains on the derivative contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets and liabilities. We do not have any leveraged derivatives, nor do we use derivative contracts for speculative purposes. ASC 815, Derivatives and Hedging, requires the fair value of all derivative instruments, including those embedded in other contracts, to be recorded as assets or liabilities in our Condensed Consolidated Balance Sheet. The related cash flow impacts of our derivative contracts are reflected as cash flows from operating activities. Our exposures are primarily related to non-U.S. dollar-denominated revenue in Europe, the U.K., Latin America, China, Israel, Australia, New Zealand, and Canada, and to non-U.S. dollar-denominated operating expenses in Europe, India, Japan, the U.K., China, Israel, Brazil, and Australia. We hedge our operating expense cash flow exposure in Indian rupees. We hedge balance sheet remeasurement exposure associated with Brazilian real, British pound sterling, Israeli shekel, Australian dollar, Japanese yen, Chinese renminbi, and Euro-denominated intercompany balances; Brazilian real, British pound sterling, Australian dollar, Israeli shekel, and Euro-denominated trade receivables, and British pound sterling, Indian rupee, and Euro-denominated net monetary assets. By their nature, derivative instruments involve, to varying degrees, elements of market and credit risk. The market risk associated with these instruments resulting from currency exchange movement is expected to offset the market risk of the underlying transactions, assets, and liabilities being hedged (i.e., operating expense exposure in Indian rupees; the collection of trade receivables denominated in currencies other than their functional currency and the settlement of intercompany balances denominated in currencies other than their functional currency). We do not believe there is significant risk of loss from non-performance by the counterparty associated with these instruments because, by policy, we deal with counterparties having a minimum investment grade or better credit rating. Credit risk is managed through the continuous monitoring of exposures to such counterparties. Cash Flow Hedges Foreign currency derivative contracts with notional amounts of $3.2 million have been designated as cash flow hedges of our Indian rupee operating expense exposure at September 30, 2016 and December 31, 2015. The fair value of the net assets (liabilities) related to these cash flow hedges are not material. The changes in fair value of these contracts are reported as a component of OCI and reclassified to operating expense in the periods of payment of the hedged operating expenses. The amount of ineffectiveness that was recorded in the Condensed Consolidated Statements of Operations for these designated cash flow hedges was immaterial. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness. Balance Sheet Hedges Forward contracts not designated for hedge accounting treatment with notional amounts of $153.6 and $115.4 million are used to hedge foreign currency balance sheet exposures at September 30, 2016 and December 31, 2015, respectively. They are not designated for hedge accounting treatment since there is a natural offset for the remeasurement of the underlying foreign currency denominated asset or liability. We recognize changes in the fair value of non-designated derivative instruments in earnings in the period of change. Gains and losses on foreign currency forward contracts used to hedge balance sheet exposures are recognized in interest income and other income (expense), net, in the same period as the remeasurement gain or loss of the related foreign currency denominated assets and liabilities. Forward contracts not designated for hedge accounting treatment consist of hedges of Brazilian real, British pound sterling, Israeli shekel, Australian dollar, Japanese yen, Chinese renminbi, and Euro-denominated intercompany balances with notional amounts of $84.6 and $63.7 million; hedges of Brazilian real, British pound sterling, Australian dollar, Israeli shekel, and Euro-denominated trade receivables with notional amounts of $56.1 and $49.1 million; and hedges of British pounds sterling, Indian rupee, and Euro-denominated other net monetary assets with notional amounts of $12.9 and $2.6 million at September 30, 2016 and December 31, 2015, respectively.

Restructuring and Related Activities [Abstract]
Restructuring and Other	11. Restructuring and Other During the three and nine months ended September 30, 2016 and 2015, cost reduction actions were taken to lower our operating expense run rate as we analyze and re-align our cost structure following our business acquisitions. These charges primarily relate to cost reduction actions undertaken to integrate recently acquired businesses, consolidate facilities, and lower our operating expense run rate. Restructuring and other consists primarily of restructuring, severance, retention, facility downsizing and relocation, and acquisition integration expenses. Our restructuring and other plans are accounted for in accordance with ASC 420, Exit or Disposal Cost Obligations, ASC 712, Compensation – Non-Retirement Postemployment Benefits, and ASC 820. Restructuring and other costs were $1.3 and $5.7 million during the three and nine months ended September 30, 2016, respectively, and $0.6 and $2.5 million during the three and nine months ended September 30, 2015, respectively. Restructuring and other costs include severance charges of $0.6 and $3.7 million related to reductions in head count of 16 and 114 during the three and nine months ended September 30, 2016, respectively, and $0.5 and $1.8 million related to reduction in head count of 17 and 65 during the three and nine months ended September 30, 2015, respectively. Severance costs include severance payments, related employee benefits, outplacement fees, and employee relocation costs. Facilities relocation and downsizing expenses were $0.6 and $0.5 million during the nine months ended September 30, 2016 and 2015, primarily related to the relocation of certain manufacturing and administrative locations to accommodate space requirements. Integration expenses of $0.6 and $1.5 million during the three and nine months ended September 30, 2016, respectively, and $0.1 and $0.2 million during the three and nine months ended September 30, 2015, were required to integrate our business acquisitions. Restructuring and other reserve activities during the nine months ended September 30, 2016 and 2015 are summarized as follows (in thousands): 2016 2015 Reserve balance at January 1, $ 3,019 $ 2,102 Restructuring 2,878 1,554 Other 2,856 991 Non-cash restructuring and other (403 ) — Cash payments (6,174 ) (2,699 ) Reserve balance at September 30, 2,176 1,948

Stock-based Compensation

Stock-based Compensation	9 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Compensation	12. Stock-based Compensation We account for stock-based payment awards in accordance with ASC 718, Stock Compensation, which requires the measurement and recognition of compensation expense for all equity awards granted to our employees and directors, including employee stock options, RSUs, and ESPP purchase rights related to all stock-based compensation plans based on the fair value of such awards on the date of grant. We amortize stock-based compensation cost on a graded vesting basis over the vesting period reduced by forfeitures, after assessing the probability of achieving the requisite performance criteria with respect to performance-based awards. Stock-based compensation cost is recognized over the requisite service period for each separately vesting tranche of the award as though the award were, in substance, multiple awards. Prior to adoption of ASU 2016-09 in the first quarter of 2016 as explained more fully in Note 1 – Basis of Presentation and Significant Accounting Policies, stock-based compensation expense included estimated forfeitures. Stock-based compensation expense related to stock options, ESPP purchase rights, and RSUs during the three and nine months ended September 30, 2016 and 2015 is summarized as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Stock -based compensation expense by type of award: RSUs $ 7,979 $ 8,209 $ 24,931 $ 24,485 ESPP 574 990 1,932 3,217 Employee stock options — 329 79 385 Total stock-based compensation expense 8,553 9,528 26,942 28,087 Income tax effect (3,649 ) (2,787 ) (7,895 ) (7,451 ) Stock-based compensation expense, net of tax $ 4,904 $ 6,741 $ 19,047 $ 20,636 Valuation Assumptions for Stock Options and ESPP Purchase Rights We use the Black-Scholes-Merton (“BSM”) option pricing model to value stock-based compensation for all equity awards, except market-based awards, which are valued using the Monte Carlo valuation model. The BSM model determines the fair value of stock-based payment awards based on the stock price on the date of grant and is affected by assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, expected term, interest rates, and actual and projected employee stock option exercise behavior. Expected volatility is based on the historical volatility of our stock over a preceding period commensurate with the expected term of the option. The expected term is based upon management’s consideration of the historical life, vesting period, and contractual period of the options granted. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yield was not considered in the option pricing formula since we do not pay dividends and have no current plans to do so in the future. Stock options were not granted during the three and nine months ended September 30, 2016 and 2015. The estimated weighted average fair value per share of ESPP purchase rights issued and the underlying weighted average assumptions for the three and nine months ended September 30, 2016 and 2015 are as follows: Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Weighted average fair value per share $ 12.00 $ 11.35 $ 10.69 $ 10.28 Expected volatility 26%-32 % 19%-25 % 22%-32 % 19%-28 % Risk-free interest rate 0.4%-0.7 % 0.1%-0.7 % 0.4%-0.8 % 0.1%-0.7 % Expected term (in years) 0.5-2.0 0.5-2.0 0.5-2.0 0.5-2.0 Stock options outstanding and exercisable, including performance-based and market-based options, as of September 30, 2016 and activity during the nine months ended September 30, 2016 are summarized below (in thousands, except weighted average exercise price and remaining contractual term): Shares Weighted Weighted Aggregate Options outstanding at January 1, 2016 443 $ 13.20 Options forfeited and expired (12 ) 10.77 Options exercised (51 ) 11.69 Options outstanding at September 30, 2016 380 $ 13.48 1.54 $ 13,467 Options vested and expected to vest at September 30, 2016 380 $ 13.48 1.54 $ 13,467 Options exercisable at September 30, 2016 380 $ 13.48 1.54 $ 13,467 Aggregate intrinsic value for stock options represents the difference between the closing price per share of our common stock on the last trading day of the fiscal period and the option exercise price multiplied by the number of in-the-money stock options outstanding, vested and expected to vest, and exercisable at September 30, 2016. Non-vested RSUs, including performance-based and market-based RSUs, as of September 30, 2016 and activity during the nine months ended September 30, 2016 are summarized below (shares in thousands): Non-vested shares Shares Weighted Non-vested at January 1, 2016 1,814 $ 40.53 Restricted stock granted 1,222 43.16 Restricted stock vested (717 ) 37.78 Restricted stock forfeited (290 ) 39.30 Non-vested at September 30, 2016 2,029 $ 43.26 Vested RSUs Performance-based RSUs that vested based on financial results are included in the period that the performance and related service criteria were met. The grant date fair value of RSUs vested during the nine months ended September 30, 2016 was $27.1 million. The aggregate intrinsic value at September 30, 2016 for RSUs expected to vest was $72.1 million and the remaining weighted average vesting period was 1.28 years. Aggregate intrinsic value for RSUs vested and expected to vest represents the closing price per share of our common stock on the last trading day of the fiscal period, multiplied by the number of RSUs vested and expected to vest as of September 30, 2016. RSUs expected to vest represent time-based RSUs unvested and outstanding at September 30, 2016, and performance-based RSUs for which the requisite service period has not been rendered, but are expected to vest based on the achievement of performance conditions. Performance-based and Market-based RSUs and Stock Options Performance-based and market-based RSUs and stock options included in the tables above as of September 30, 2016 and activity during the nine months ended September 30, 2016 are summarized below (in thousands): Performance-based Market-based RSUs Stock RSUs Non-vested at December 31, 2015 920 16 23 Granted 730 — — Vested (223 ) (4 ) — Forfeited (244 ) (12 ) — Non-vested at September 30, 2016 1,183 — 23 Performance-based and market-based stock options were not granted during the nine months ended September 30, 2016. We use the BSM option pricing model to value performance-based RSUs. The weighted average grant date fair value per share of performance-based RSUs granted and the assumptions used to estimate grant date fair value during the nine months ended September 30, 2016 and 2015 are as follows: Performance-based Market-based RSUs RSUs Short-term Long-term Nine months ended September 30, 2016 Grants Grant date fair value per share $ 39.79 $ 45.62 Service period (years) 1.0 2.0 - 3.0 Nine months ended September 30, 2015 Grants Grant date fair value per share $ 38.77 $ 42.76 $ 33.84 Service period (years) 1.0 2.0 - 3.0 Derived service period (years) 1.6 Implied volatility 30.0 % Risk-free interest rate 1.7 % Our performance-based RSUs generally vest when specified performance criteria are met based on bookings, revenue, cash provided by operating activities, non-GAAP operating income, non-GAAP earnings per share, revenue growth compared to market comparables, non-GAAP earnings per share growth compared to cash flow from operating activities growth, or other targets during the service period; otherwise, they are forfeited. Non-GAAP operating income is defined as operating income determined in accordance with GAAP, adjusted to remove the impact of certain expenses. Non-GAAP earnings per share is defined as net income determined in accordance with GAAP, adjusted to remove the impact of certain expenses, divided by the weighted average number of common shares and dilutive potential common shares outstanding during the period as more fully defined in Note 2 – Earnings Per Share of the Notes to Consolidated Financial Statements. The grant date fair value per share determined in accordance with the BSM valuation model is being amortized over the service period of the performance-based awards. The probability of achieving the awards was determined based on review of the actual results achieved thus far by each business unit compared with the operating plan during the pertinent service period as well as the overall strength of the business unit. Stock-based compensation expense was adjusted based on this probability assessment. As actual results are achieved during the service period, the probability assessment is updated and stock-based compensation expense adjusted accordingly.

Equity [Abstract]
Common Stock Repurchase Programs	13. Common Stock Repurchase Programs On November 6, 2013, the board of directors approved the repurchase of $200 million of outstanding common stock. Under this publicly announced plan, we repurchased 1.5 million shares for an aggregate purchase price of $65.7 million during the year ended December 31, 2015. On November 9, 2015, the board of directors cancelled $54.9 million remaining for repurchase under the 2013 authorization and approved a new authorization to repurchase $150 million of outstanding common stock commencing January 1, 2016. This authorization expires December 31, 2018. We repurchased 0.4 and 1.4 million shares for an aggregate purchase price of $18.0 and $57.7 million during the three and nine months ended September 30, 2016. Our employees have the option to surrender shares of common stock to satisfy their tax withholding obligations that arise on the vesting of RSUs. In connection with stock option exercises, certain employees can surrender shares to satisfy the exercise price of certain stock options and any tax withholding obligations incurred in connection with such exercises. Employees surrendered less than 0.1 and 0.2 million shares for an aggregate purchase price of $3.4 and $7.6 million during the three and nine months ended September 30, 2016, respectively, and 0.1 and 0.2 million shares for an aggregate purchase price of $6.0 and $10.5 million during the three and nine months ended September 30, 2015, respectively. These repurchased shares reduce shares outstanding and are recorded as treasury stock under the cost method thereby reducing stockholders’ equity by the cost of the repurchased shares. Our buyback program is limited by SEC regulations and is subject to compliance with our insider trading policy.

Receivables [Abstract]
Accounts Receivable	14. Accounts Receivable Financing Receivables ASC 310, Receivables, requires disclosure regarding the credit quality of our financing receivables and allowance for credit losses including disclosure of credit quality indicators, past due information, and modifications of our financing receivables. We had financing receivables of $24.1 and $14.8 million consisting of $11.7 and $10.2 million of sales-type lease receivables, included within other current assets and other assets at September 30, 2016 and December 31, 2015, respectively, and $12.4 and $4.6 million of trade receivables having an original contractual maturity in excess of one year, included within accounts receivable, net of allowance, at September 30, 2016 and December 31, 2015, respectively. The trade receivables of $12.4 and $4.6 million having an original total contractual maturity in excess of one year at September 30, 2016 and December 31, 2015, include $7.4 and $3.2 million, respectively, which are scheduled to be received in less than one year. The credit quality of financing receivables is evaluated on the same basis as trade receivables. We do not have material past due financing receivables. Accounts Receivable Sales Arrangements In accordance with ASC 860-20, Transfers and Servicing, trade receivables are derecognized from our Condensed Consolidated Balance Sheet when sold to third parties upon determining that such receivables are presumptively beyond the reach of creditors in a bankruptcy proceeding. The recourse obligation is measured using market data from similar transactions and the servicing liability is determined based on the fair value that a third party would charge to service these receivables. These liabilities were determined to not be material at September 30, 2016 and December 31, 2015. We have facilities in the U.S. and Italy that enable us to sell to third parties, on an ongoing basis, certain trade receivables with recourse. Trade receivables sold with recourse are generally short-term receivables with payment due dates of less than 10 days from the date of sale, which are subject to a servicing obligation. Trade receivables sold under these facilities were $3.0 and $15.4 million during the three and nine months ended September 30, 2016, respectively, and $ 23.2 million during the year ended December 31, 2015, which approximates the cash received. We have facilities in Spain and Italy that enable us to sell to third parties, on an ongoing basis, certain trade receivables without recourse. Trade receivables sold without recourse are generally short-term receivables with payment due dates of less than one year, which are secured by international letters of credit. Trade receivables sold under these facilities were $1.0 and $2.2 million during the three and nine months ended September 30, 2016, respectively, and $3.7 million during the year ended December 31, 2015, which approximates the cash received. We report collections from the sale of trade receivables to third parties as operating cash flows in the Condensed Consolidated Statements of Cash Flows.

Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements (“condensed consolidated financial statements”) include the accounts of Electronics For Imaging, Inc. and its subsidiaries (“EFI” or “Company”). All intercompany accounts and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP” or “GAAP”) for interim financial information, rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements, and accounting policies consistent in all material respects with those applied in preparing our audited annual consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015. These condensed consolidated financial statements and accompanying notes should be read in conjunction with our annual consolidated financial statements and the notes thereto for the year ended December 31, 2015, included in our Annual Report on Form 10-K. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments, management considers necessary for the fair presentation of our financial position, operating results, comprehensive income, and cash flows for the interim periods presented. Our results for the interim periods are not necessarily indicative of results for the entire year.
Segment Reporting	Operating segment information is required to be presented based on the internal reporting used by the chief operating decision making group (“CODM”) to allocate resources and evaluate operating segment performance. Our CODM is comprised of our Chief Executive Officer and Chief Financial Officer. The CODM group is focused on assessment and resource allocation among the Industrial Inkjet, Productivity Software, and Fiery operating segments. Our operating segments are integrated through their reporting and operating structures, shared technology and practices, shared sales and marketing, and combined production facilities. Our enterprise management processes use financial information that is closely aligned with our three operating segments at the gross profit level. Relevant discrete financial information is prepared at the gross profit level for each of our three operating segments, which is used by the CODM to allocate resources and assess the performance of each operating segment.

ASU 2016-08 Principal Vs Agent [Member]
Recent Accounting Pronouncements	Principal vs Agent. A number of indicators of the nature of the relationship that are considered under current guidance have been streamlined and clarified in the new guidance by focusing more specifically on the performance obligations that must be fulfilled in the transaction, which entity carries the inventory risk in the transaction, and which entity controls the pricing of the good or service. Credit risk will no longer be a criterion. This guidance will be effective in the first quarter of 2018. We are evaluating its impact on our revenue and results of operations.
ASU 2016-02 Lease Arrangements [Member]
Recent Accounting Pronouncements	Lease Arrangements. The recognition, measurement, and presentation of expenses and cash flows by a lessee have not significantly changed from previous guidance. There continues to be a differentiation between finance leases and operating leases. The criteria for determining whether a lease is a financing or operating lease are substantially the same as existing guidance except that the “bright line” percentages have been removed. • For finance leases, interest is recognized on the lease liability separately from depreciation of the right-of-use asset in the statement of operations. Principal repayments are classified within financing activities and interest payments are classified as operating activities in the statement of cash flows. • For operating leases, a lessee is required to recognize lease expense generally on a straight-line basis. All operating lease payments are classified as operating activities in the statement of cash flows. The current build-to-suit lease accounting guidance will be rescinded by the new guidance, although simplified guidance will remain regarding lessee control during the construction period. Consequently, the accounting for build-to-suit leases will be the same as finance leases unless the lessee control provisions are applicable.

ASU 2016-09 Stock-based Compensation [Member]
Recent Accounting Pronouncements	Stock-based Compensation. • Under the new guidance, all excess tax benefits and deficiencies are recognized as income tax expense. Excess tax benefits of less than $0.1 million that were charged to additional paid-in capital in the first quarter of 2016 were reversed upon adoption. We recorded $2.2 million of deferred tax assets related to excess tax benefits for federal research and development income tax credits not previously benefitted. • The requirement to reclassify gross excess tax benefits related to stock-based compensation from operating to financing activities in the statement of cash flows is eliminated. The reclassification of $0.2 million in the first quarter of 2016 has been reversed upon adoption. We applied this guidance retrospectively to all prior periods to maintain the comparability of presentation between periods, which resulted in a $0.3 million increase in cash flows provided by operating activities during the nine months ended September 30, 2015, and a corresponding decrease in cash flows provided by financing activities. • We have elected to account for forfeitures when they occur instead of estimating the expected forfeiture rate. Adoption of this provision during the second quarter resulted in a retroactive net income adjustment of $0.2 million, net of tax effect, in the first quarter of 2016 and a cumulative effect adjustment to retained earnings of $2.1 million, net of tax, as of January 1, 2016. • Statutory tax withholding will be permitted up to the maximum statutory tax rate in applicable jurisdictions. The retrospective impact of this provision on prior period financial statements is not material.
ASU 2014-09 and ASU 2016-10 Revenue Recognition [Member]
Recent Accounting Pronouncements	Revenue Recognition. The guidance requires comprehensive annual and interim disclosures regarding the nature, amount, timing, and uncertainty of recognized revenue. Qualitative and quantitative disclosures will be required regarding: • contracts with customers, including revenue and impairments recognized, disaggregation, and information about contract balances and performance obligations, • significant judgments and changes in judgments required to determine the transaction price, amounts allocated to performance obligations, and the timing for recognizing revenue resulting from the satisfaction of performance obligations, and • assets recognized from the costs to obtain or fulfill a contract. The guidance will be effective in the first quarter of 2018. We are evaluating its impact on our revenue and results of operations.

Accordingly, $63.6 million debt discount attributable to the difference between the 0.75% coupon interest rate on our Notes and the 4.98% (5.46% inclusive of debt issuance costs) effective interest rate will be classified as an operating cash outflow in the Condensed Consolidated Statement of Cash Flows upon cash settlement in 2019.
