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, 10-K, Correction of Prior Period Financial Information During the preparation of the consolidated financial statements for three and nine months ended September 30, 2017, we identified certain errors at our Italian manufacturing subsidiary attributable to the valuation and classification of certain finished goods inventory. The errors related to finished goods that should have been impaired and expensed in 2015, inventory utilized in research and development projects that expired and should have been expensed in 2016, and certain assets included in inventory that should have been capitalized and depreciated over their estimated useful lives. The preceding resulted in an understatement of cost of revenue in 2015 and operating expenses in 2016 due to failure to properly impair and expense certain items and properly classify certain amounts included in inventories on the balance sheet and appropriately depreciate those amounts. As a result, we have corrected the accompanying condensed consolidated balance sheet as of December 31, 2016 as follows: December 31, 2016 As Adjustments As Adjusted (in thousands) Inventories $ 99,075 $ (2,737 ) $ 96,338 Property and equipment, net 103,304 170 103,474 Total assets 1,481,496 (2,567 ) 1,478,929 Deferred tax liabilities 16,351 (750 ) 15,601 Total liabilities 653,664 (750 ) 652,914 Accumulated other comprehensive loss (24,694 ) 119 (24,575 ) Retained earnings 419,825 (1,936 ) 417,889 Total shareholders’ equity 827,832 (1,817 ) 826,015 We consider this correction to previously issued financial statements to be immaterial. The impact to net income for the years ended December 31, 2016 and 2015 for this correction is a decrease of $0.6 and $1.3 million, respectively, from amounts previously reported of $45.5 and $33.5 million, respectively. Significant Accounting Policies There have been no material changes in our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K, Bill and Hold Transactions. “bill-and-hold” “bill-and-hold” “bill-and-hold” Out-of-Period In the nine months ended September 30, 2017, we recorded out-of-period Recent Accounting Pronouncements Inventory Valuation. 2015-11, 2015-11 2015-11 Revenue Recognition. 2014-09, 2016-10, ASU 2014-09 2014-09: • disaggregation of our current disclosures of revenue by segment and geographic area into categories that depict how revenue and cash flows are impacted by economic factors, • timing of recognition, contract duration, and sales channel, • billed and unbilled 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, • assets recognized from the costs to obtain or fulfill a contract (e.g., commissions), and • bad debt provisions related to billed and unbilled receivables. Upon evaluation, we believe the key changes in the guidance that impact our revenue recognition relate to the timing of revenue recognition and allocation of contract revenue between services and software licenses. The requirement to defer incremental contract acquisition costs (e.g., commissions) and recognize them over the contract period or expected customer life will result in the recognition of a deferred charge on our balance sheet. We are assessing the impact on our consolidated financial statements, systems, and controls upon adoption. Principal vs Agent. 2016-08, Several 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 related to third party ink revenue and certain printer components. Financial Instruments. 2016-13, available-for-sale available-for-sale ASU 2016-13 available-for-sale Settlement of Convertible Debt. 2016-15, ASU 2016-15 Restricted Cash. 2016-18, beginning-of-period end-of-period ASU 2016-18 off-balance Lease Arrangements. 2016-02, right-of-use right-to-use 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 • 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 build-to-suit We have not quantified the impact, but the requirement to recognize a right-of-use Definition of a Business. 2017-01, Under ASU 2017-01, Our condensed consolidated financial statements may be impacted if an acquisition does not qualify as a business combination after ASU 2017-01 Nonfinancial Asset Derecognition. 2017-05, 2014-09) ASU 2017-05 Stock Compensation Modification. 2017-09, ASU 2017-09 Hedge Accounting. 2017-12, Our foreign currency derivative contracts include notional amounts of $3.8 million that have been designated as cash flow hedges of our Indian rupee operating expense exposure at September 30, 2017. Under current guidance, changes in the fair value of the effective portion of these contracts are reported as a component of other comprehensive income (“OCI”) and reclassified to operating expense in the periods of payment of the hedged cash flows. The ineffective portion is recognized as a component of interest income and other income, net. Under the new guidance, the entire change in the fair value of hedging instruments designated as cash flow hedges that are included in the assessment of hedge effectiveness will be recorded in OCI. Those amounts are reclassified to earnings in the periods of payment in the same income statement line item as the hedged operating expenses. Upon adoption, a cumulative-effect adjustment will be required to charge the ineffective portion of derivative contracts designated as cash flow hedges existing at the date of adoption to accumulated OCI with a corresponding adjustment to the retained earnings as of the beginning of the fiscal year of the adoption. The new guidance continues to require an initial prospective quantitative hedge effectiveness assessment unless the hedging relationship qualifies for the critical-terms-match method or facts and circumstances method, which permit an assumption of perfect hedge effectiveness. After the initial quantitative assessment, the new guidance permits a qualitative ongoing effectiveness assessment for certain hedges if we can reasonably support an expectation of high effectiveness throughout the term of the hedge. The new guidance also requires additional disclosure related to the effect on the income statement of cash flow hedges.

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 non-vested 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. non-GAAP non-GAAP Basic and diluted earnings per share during the three and nine months ended September 30, 2017 and 2016 are reconciled as follows (in thousands, except per share amounts): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 Basic net income per share: Net income available to common shareholders $ 3,454 $ 17,662 $ 11,000 $ 25,000 Weighted average common shares outstanding 46,348 46,794 46,442 46,983 Basic net income per share $ 0.07 $ 0.38 $ 0.24 $ 0.53 Dilutive net income per share: Net income available to common shareholders $ 3,454 $ 17,662 $ 11,000 $ 25,000 Weighted average common shares outstanding 46,348 46,794 46,442 46,983 Dilutive stock options and non-vested 589 827 660 808 Weighted average common shares outstanding for purposes of computing diluted net income per share 46,937 47,621 47,102 47,791 Dilutive net income per share $ 0.07 $ 0.37 $ 0.23 $ 0.52 Potential shares of common stock that were not included in the determination of diluted net income per share for the periods presented because the impact of including them would have been anti-dilutive or performance conditions have not been met, consisted of the following (in thousands): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 RSUs 327 669 304 601 ESPP purchase rights 410 14 342 29 Total potential shares of common stock excluded from the computation of diluted earnings per share 737 683 646 630 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 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 privately held Generation Digital Solutions, Inc. (“GD”), CRC Information Systems, Inc. (“CRC”) from Reynolds and Reynolds Company (“Reynolds”), and certain assets comprising the FFPS business from Xerox Corporation (“Xerox”), during 2017, which have been included in our Fiery or Productivity Software operating segments. Acquisition-related transaction costs were $0.6 and $1.8 million during the three and nine months ended September 30, 2017, respectively, and $0.4 and $1.7 million during the three and nine months ended September 30, 2016, respectively, related to all acquisitions. 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 based on their estimated fair value on their 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 opportunity to integrate acquired technology into our products, the positive reputation of GD, CRC, and FFPS in the market, integration of the GD digital textile design workflow with our Fiery textile digital front ends (“DFEs”) and Reggiani digital textile printers linking textile design and production, the opportunity to sell Fiery DFEs to FFPS customers, and the opportunity to expand our presence in the DFE market through the synergy of FFPS technology with existing Fiery products. 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 measurement period 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 measurement period, which end at various dates in 2018. Measurement period adjustments will be recognized in the reporting period in which the adjustment amounts are determined, if any. Fiery Operating Segment We acquired privately held GD, which is a New York corporation headquartered in New York City on August 14, 2017 for cash consideration of $3.2 million, net of cash acquired, plus an additional potential future cash earnout, which is contingent on achieving certain revenue and operating profit performance targets during a six-month 12-month The fair value of the earnout related to the GD acquisition is currently estimated to be $3.6 million at September 30, 2017, by applying the income approach in accordance with ASC 805-30-25-5, 820-10-35 805-30-35-1, We acquired certain assets comprising the FFPS business from Xerox, a New York corporation headquartered in Norwalk, Connecticut, on January 31, 2017. The FFPS business manufactures and markets the FFPS DFE, which is a DFE that previously competed with our Fiery DFEs and is included in our Fiery operating segment. We purchased FFPS for cash consideration of $23.9 million consisting of $5.9 million paid at closing, $9.0 million paid in July 2017, and $9.0 million payable in July 2018, which have been discounted at our incremental borrowing rate of 4.98%, resulting in a purchase price of $23.1 million. Productivity Software Operating Segment We acquired privately held CRC, which is a Michigan corporation headquartered in Scottsdale, Arizona, from Reynolds, which is an Ohio corporation headquartered in Dayton, Ohio, on May 8, 2017, for cash consideration of $7.6 million. CRC provides business process automation software for label and packaging printers for commercial businesses and is included in the Midmarket Print Suite within our Productivity Software operating segment. Valuation Methodologies Intangible assets acquired consist of customer relationships, the Master Purchasing Agreement (the “Purchasing Agreement”) with Xerox, “take-or-pay” in-process Customer Relationships and Backlog Trade Names Existing Technologies Purchasing Agreement Take-or-pay 12-month one-time IPR&D 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: Fiery Productivity Software FFPS GD CRC Weighted average Purchase Weighted average Purchase Weighted average Purchase Purchasing agreement 10 years $ 9,330 — $ — — $ — Take-or-pay 4 years 9,000 — — — — Customer relationships — — 8 years 3,030 9 years 3,580 Existing technology 2 years 2,570 5 years 890 4 years 540 Trade names 5 years 1,020 5 years 290 4 years 180 IPR&D less than one year 70 — — — — Backlog — — — — less than one year 4 Goodwill — 6,236 — 3,012 — 4,595 28,226 $ 7,222 $ 8,899 Net tangible assets (liabilities) (5,092 ) (298 ) (1,299 ) Total purchase price $ 23,134 $ 6,924 $ 7,600 Pro forma results of operations have not been presented because they are not material to our Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017 and 2016. Goodwill, which represents the excess of the purchase price over the net tangible and intangible assets acquired, that was generated by our acquisition of CRC is not deductible for tax purposes. Goodwill that was generated by our acquisitions of GD and FFPS is deductible for tax purposes.

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, municipal government, 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 Available-for-sale Our available-for-sale Amortized cost Gross unrealized Gross unrealized losses Fair value September 30, 2017 U.S. Government and sponsored entities $ 65,345 $ 2 $ (358 ) $ 64,989 Corporate debt securities 138,399 152 (200 ) 138,351 Municipal government 1,047 — (1 ) 1,046 Asset-backed securities 12,823 47 (21 ) 12,849 Mortgage-backed securities – residential 689 1 (2 ) 688 Total short-term investments $ 218,303 $ 202 $ (582 ) $ 217,923 December 31, 2016 U.S. Government and sponsored entities $ 70,893 $ 49 $ (348 ) $ 70,594 Corporate debt securities 198,166 102 (621 ) 197,647 Municipal government 1,278 — (1 ) 1,277 Asset-backed securities 24,233 79 (17 ) 24,295 Mortgage-backed securities – residential 1,615 3 (3 ) 1,615 Total short-term investments $ 296,185 $ 233 $ (990 ) $ 295,428 The fair value and duration that investments, including cash equivalents, have been in a gross unrealized loss position as of September 30, 2017, and December 31, 2016 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, 2017 U.S. Government and sponsored entities $ 45,777 $ (158 ) $ 18,040 $ (199 ) $ 63,817 $ (357 ) Corporate debt securities 57,158 (138 ) 21,315 (63 ) 78,473 (201 ) Municipal government 379 (1 ) — — 379 (1 ) Asset-backed securities 11,959 (20 ) 805 (1 ) 12,764 (21 ) Mortgage-backed securities – residential 351 (2 ) 11 — 362 (2 ) Total $ 115,624 $ (319 ) $ 40,171 $ (263 ) $ 155,795 $ (582 ) December 31, 2016 U.S. Government and sponsored entities $ 39,810 $ (348 ) $ — $ — $ 39,810 $ (348 ) Corporate debt securities 133,382 (581 ) 13,158 (40 ) 146,540 (621 ) Municipal government 1,268 (1 ) — — 1,268 (1 ) Asset-backed securities 4,540 (7 ) 4,611 (10 ) 9,151 (17 ) Mortgage-backed securities – residential 428 (1 ) 153 (2 ) 581 (3 ) Total $ 179,428 $ (938 ) $ 17,922 $ (52 ) $ 197,350 $ (990 ) For fixed income securities that have unrealized losses as of September 30, 2017, 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, 2017, were temporary in nature. Amortized cost and estimated fair value of investments as of September 30, 2017, are summarized by maturity date as follows (in thousands): Amortized cost Fair value Mature in less than one year $ 56,677 $ 56,646 Mature in one to three years 161,626 161,277 Total short-term investments $ 218,303 $ 217,923 Net realized gains of less than $0.1 and $0.2 million from sales of investments were recognized in interest income and other income, net, during the three and nine months ended September 30, 2017, respectively. Net realized gains of $0.1 and $0.3 million from sales of investments were recognized in interest income and other income, net, during the three and nine months ended September 30, 2016, respectively. Net unrealized losses of $0.4 and $0.8 million were included in OCI in the accompanying Condensed Consolidated Balance Sheets as of September 30, 2017, and December 31, 2016, respectively. Fair Value Measurements ASC 820, Fair Value Measurements, 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, 2017, and December 31, 2016 in order of liquidity as follows (in thousands): Total Quoted Prices Significant Unobservable (Level 3) September 30, 2017 Assets: Money market funds $ 24,426 $ 24,426 $ — $ — U.S. Government and sponsored entities 64,989 38,966 26,023 — Corporate debt securities 138,351 — 138,351 — Municipal government 1,046 — 1,046 — Asset-backed securities 12,849 — 12,795 54 Mortgage-backed securities – residential 687 — 687 — $ 242,348 $ 63,392 $ 178,902 $ 54 Liabilities: Contingent consideration, current and noncurrent $ 53,520 $ — $ — $ 53,520 Self-insurance 935 — — 935 $ 54,455 $ — $ — $ 54,455 December 31, 2016 Assets: Money market funds $ 23,575 $ 23,575 $ — $ — U.S. Government and sponsored entities 70,594 51,870 18,724 — Corporate debt securities 197,647 — 197,647 — Municipal government 1,277 — 1,277 — Asset-backed securities 24,295 — 24,228 67 Mortgage-backed securities – residential 1,615 — 1,615 — $ 319,003 $ 75,445 $ 243,491 $ 67 Liabilities: Contingent consideration, current and noncurrent $ 56,463 $ — $ — $ 56,463 Self-insurance 1,542 — — 1,542 $ 58,005 $ — $ — $ 58,005 Money market funds consist of $24.4 and $23.6 million, which have been classified as cash equivalents as of September 30, 2017, and December 31, 2016, 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, 2017 and 2016. 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 GD in 2017; Optitex Ltd. (“Optitex”) and Rialco Limited (“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”) and PrintLeader Software (“PrintLeader”) in 2013. The fair value of these earnouts is estimated to be $53.5 and $56.5 million as of September 30, 2017, and December 31, 2016, respectively, by applying the income approach in accordance with ASC 805-30-25-5. 820-10-35 The fair value of contingent consideration increased by $2.2 million, including $1.2 million of earnout interest accretion related to all acquisitions during the nine months ended September 30, 2017. The Optitex and CTI earnout performance probabilities increased while the Shuttleworth earnout performance probability decreased in 2017. The fair value of contingent consideration increased by $6.8 million, including $2.7 million of earnout interest accretion related to all acquisitions during the year ended December 31, 2016. The Rialco, Optitex, Reggiani, DirectSmile, and CTI earnout performance probabilities increased while the DIMS and Shuttleworth earnout performance probabilities decreased or were not achieved in 2016. In accordance with ASC 805-30-35-1, Earnout payments and settlements during the nine months ended September 30, 2017 of $8.9, $1.3, and $1.2 million are primarily related to the previously accrued Reggiani, Rialco, and Shuttleworth contingent consideration liabilities, respectively. Earnout payments during the year ended December 31, 2016 of $23.8, $3.6, $0.4, and $0.2 million are primarily related to the previously accrued Reggiani, DirectSmile, SmartLinc, and Metrix contingent consideration liabilities, respectively. Changes in the fair value of contingent consideration are summarized as follows (in thousands): Fair value of contingent consideration at January 1, 2016 $ 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 6,813 Payments (28,111 ) Foreign currency adjustment (1,444 ) Fair value of contingent consideration at December 31, 2016 $ 56,463 Fair value of GD contingent consideration at August 14, 2017 $ 3,600 Changes in valuation $ 2,187 Payments and settlements (11,559 ) Foreign currency adjustment 2,829 Fair value of contingent consideration at September 30, 2017 $ 53,520 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 $1.7 million or a decrease in the fair value of contingent consideration of $2.8 million, resulting in a corresponding adjustment to general and administrative expense. A change in the discount rate of one percentage point would result in an increase in the fair value of contingent consideration of $0.4 million or a decrease of $0.5 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 $13.5 million as of September 30, 2017. 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 $191.8 and $161.8 million as of September 30, 2017 and December 31, 2016, respectively. The fair value of our derivative assets and liabilities that were designated for cash flow hedge accounting treatment having notional amounts of $3.8 and $3.2 million as of September 30, 2017 and December 31, 2016, 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 fair value of the Notes as of September 30, 2017 was approximately $360.9 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, 2017, 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 if it continues to meet the conditions for equity classification. We allocated the total transaction costs incurred by the Notes 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, 2017, and December 31, 2016 (in thousands): September 30, December 31, Liability component $ 345,000 $ 345,000 Debt discount, net of amortization (26,488 ) (36,115 ) Debt issuance costs, net of amortization (3,258 ) (4,401 ) Net carrying amount $ 315,255 $ 304,484 Equity component $ 63,643 $ 63,643 Less: debt issuance costs allocated to equity (1,582 ) (1,582 ) Net carrying amount $ 62,061 $ 62,061 Interest expense recognized related to the Notes during the three and nine months ended September 30, 2017 and 2016 was as follows (in thousands): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 0.75% coupon $ 647 $ 654 $ 1,933 $ 1,941 Amortization of debt issuance costs 388 373 1,144 1,092 Amortization of debt discount 3,265 3,126 9,627 9,152 $ 4,300 $ 4,153 $ 12,704 $ 12,185 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 corresponds 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

Income taxes	7. Income taxes We recognized tax provisions of $0.8 million on pretax net income of $4.2 and $11.8 million during the three and nine months ended September 30, 2017, respectively. We recognized tax benefits of $11.8 and $9.0 million on pretax net income of $5.8 and $16.0 million during the three and nine months ended September 30, 2016, respectively. The provisions for income taxes before discrete items reflected in the table below were $1.9 and $4.5 million during the three and nine months ended September 30, 2017, respectively, and $3.3 and $6.1 million during the three and nine months ended September 30, 2016, respectively. The decrease in the provisions for income taxes before discrete items for the three and nine months ended September 30, 2017, compared with the same periods in the prior year, is primarily due to decreased 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, the tax effects of stock-based compensation expense pursuant to ASC 718-740, non-deductible Our tax provisions before discrete items are reconciled to our recorded benefits for income taxes during the three and nine months ended September 30, 2017 and 2016 as follows (in millions): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 Provision for income taxes before discrete items $ 1.9 $ 3.3 $ 4.5 $ 6.1 Interest related to unrecognized tax benefits — — 0.1 0.3 Reassessment of taxes upon filing tax returns 0.3 (0.2 ) 0.4 (0.2 ) Provision (benefit) related to stock based compensation, including ESPP dispositions 0.4 (1.4 ) (1.9 ) (1.7 ) Benefit from reassessment of taxes upon foreign statutory tax rate change — — (0.5 ) — Benefit from reversals of uncertain tax positions due to statute of limitation expirations (1.8 ) (13.5 ) (1.8 ) (13.5 ) Benefit from income taxes $ 0.8 $ (11.8 ) $ 0.8 $ (9.0 ) As of September 30, 2017, and December 31, 2016, gross unrecognized benefits that would affect the effective tax rate if recognized were $32.3 and $32.0 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 $5.0 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, We recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of September 30, 2017 and December 31, 2016, we have accrued $0.6 and $0.5 million, respectively, for potential payments of interest and penalties. We are subject to examination by the Internal Revenue Service (“IRS”) for the 2014-2015 tax years, state tax jurisdictions for the 2012-2015 tax years, the Netherlands tax authority for the 2012-2015 tax years, the Spanish tax authority for the 2013-2016 tax years, the Israel tax authority for the 2011-2015 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, 2017, 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 In 2016, management approved a plan to sell approximately 5.6 acres and the office building located at 1340 Corporate Center Curve, Eagan, Minnesota, consisting of 43,682 square feet, and the related fixed assets were classified as held for sale. On April 13, 2017, we entered into an agreement under which we agreed to sell the office building and related land, subject to completion of a 150-day Off-Balance On August 26, 2016, we entered into a lease agreement and have accounted for a lease term of 48.5 years, inclusive of two renewal options of 5.0 and 3.5 years, with the City of Manchester to lease 16.9 acres adjacent to the Manchester Regional Airport. The land is subleased to Bank of Tokyo – Mitsubishi UFJ Leasing & Finance LLC (“BTMU”) during the term of the lease related to the manufacturing facility that is being constructed on the site, which is described below. Minimum lease payments are $13.1 million during the 48.5 year term of the land lease, excluding four months of the land lease that are financed into the manufacturing facility lease. On August 26, 2016, we entered into a six-year six-year six-year The funds pledged under the lease represent 115% of the total expenditures made by BTMU through September 30, 2017. The funds are invested in $20.9 and $6.8 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 lease period. The funds pledged as collateral are invested in U.S. government securities and cash equivalents as of September 30, 2017, 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, 2017. We have determined that the lease agreement does not qualify as a variable interest entity under ASC 810-10, 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, 2017, we are subject to the matters 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 an 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 $10.1 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. Purported Class Action Lawsuit On August 10, 2017, a putative class action was filed against the Company and its two named executive officers in the United States District Court for the District of New Jersey, captioned Pipitone v. Electronics For Imaging, Inc 2:17-cv-05992 At this time, we do not believe it is probable that we will incur a material loss in this matter. However, it is reasonably possible that our financial statements could be materially affected by an unfavorable resolution of this matter. Because this matter is in the preliminary stages, we are not yet in a position to estimate the amount or range of reasonably possible loss that may be incurred. Purported Derivative Shareholder Lawsuits On August 22, 2017, a purported derivative shareholder complaint was filed in the Superior Court of the State of California for the County of Alameda captioned Schiffmiller v. Gecht Pipitone At this time, we do not believe it is probable that we will incur a material loss in this matter. However, it is reasonably possible that our financial statements could be materially affected by an unfavorable resolution of this matter. Because this matter has been stayed pending resolution of the Pipitone Other Matters As of September 30, 2017, 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, end-to-end Productivity Suite Packaging Suite, Corrugated Packaging Suite, Enterprise Commercial Print Suite, Publication Print Suite, Midmarket Print Suite, Quick Print Suite, in-plant Value Added Products, web-to-print, e-commerce, 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 Operating segment profit (i.e., gross profit), excluding stock-based compensation expense, during the three and nine months ended September 30, 2017 and 2016 is summarized as follows (in thousands): Three Months Ended Nine Months Ended 2017 2016 2017 2016 Industrial Inkjet Revenue $ 142,930 $ 143,004 $ 407,886 $ 408,926 Gross profit 53,392 50,433 154,972 141,927 Gross profit percentages 37.4 % 35.3 % 38.0 % 34.7 % Productivity Software Revenue $ 37,171 $ 39,663 $ 111,292 $ 108,554 Gross profit 26,667 30,041 81,431 80,961 Gross profit percentages 71.7 % 75.7 % 73.2 % 74.6 % Fiery Revenue $ 68,258 $ 62,908 $ 204,919 $ 207,878 Gross profit 47,885 45,362 143,821 147,938 Gross profit percentages 70.2 % 72.1 % 70.2 % 71.2 % 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, 2017 and 2016 as follows (in thousands): Three Months Ended Six Months Ended 2017 2016 2017 2016 Segment gross profit $ 127,944 $ 125,836 $ 380,224 $ 370,826 Stock-based compensation expense (486 ) (642 ) (1,985 ) (1,873 ) Other items excluded from segment profit — — — (315 ) Gross profit $ 127,458 $ 125,194 $ 378,239 $ 368,638 The Fiery gross profit percentage is impacted by less than $0.1 and $1.3 million during the three and nine months ended September 30, 2017, respectively, charged to cost of revenue, which reflects the cost of manufacturing plus a portion of the expected profit margin related to the acquired FFPS inventories. Inventory acquired in the acquisition of FFPS is required to be recorded at fair value rather than historical cost in accordance with ASC 805. This amount is not included in the financial information regularly reviewed by the CODM as this acquisition-related charge is not indicative of the gross margin trends in the FFPS business. Excluding this charge, the Fiery gross profit percentage would be 70.3% and 70.8% for the three and nine months ended September 30, 2017, respectively.

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 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. non-U.S. 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 respective reporting entity’s functional currency, and the settlement of intercompany balances denominated in currencies other than their functional currency). Under our master netting agreements with our foreign currency derivative counterparties, we are allowed to net transactions of the same currency with a single net amount payable by one party to the other. The derivatives held by us are not subject to any credit contingent features negotiated with these counterparties. We are not required to pledge cash collateral related to these foreign currency derivative contracts. We do not believe there is significant risk of loss from non-performance Cash Flow Hedges Foreign currency derivative contracts with notional amounts of $3.8 million and $3.2 million have been designated as cash flow hedges of our Indian rupee operating expense exposure at September 30, 2017 and December 31, 2016, respectively. 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 $188.0 and $158.7 million are used to hedge foreign currency balance sheet exposures at September 30, 2017 and December 31, 2016, 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

Restructuring and Other During the three and nine months ended September 30, 2017 and 2016, cost reduction actions were taken to lower our operating expense run rate as we analyze and re-align Non-Retirement Restructuring and other costs were $0.8 and $5.4 million during the three and nine months ended September 30, 2017, respectively, and $1.3 and $5.7 million during the three and nine months ended September 30, 2016, respectively. Restructuring and other costs include severance charges of $0.3 and $3.8 million related to reductions in head count of 15 and 128 during the three and nine months ended September 30, 2017, respectively, and $0.6 and $3.7 million related to reduction in head count of 16 and 114 during the three and nine months ended September 30, 2016, respectively. Severance costs include severance payments, related employee benefits, outplacement fees, and employee relocation costs. Facilities relocation and downsizing expenses were $0.4 and $0.6 million during the three and nine months ended September 30, 2017, respectively, and $0.1 and $0.6 million during the three and nine months ended September 30, 2016, primarily related to the relocation of certain administrative locations due to reduced space requirements.

Stock-based Compensation

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 RSUs, ESPP purchase rights, and employee stock options 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 actual 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. Stock-based compensation expense related to stock options, ESPP purchase rights, and RSUs during the three and nine months ended September 30, 2017 and 2016 is summarized as follows (in thousands): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 Stock-based compensation expense by type of award: RSUs $ 3,545 $ 7,979 $ 18,875 $ 24,931 ESPP purchase rights 1,103 574 3,666 1,932 Employee stock options — — — 79 Total stock-based compensation 4,648 8,553 22,541 26,942 Income tax benefit (1,525 ) (3,649 ) (6,929 ) (7,895 ) Stock-based compensation expense, net of tax $ 3,123 $ 4,904 $ 15,612 $ 19,047 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 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, 2017 and 2016. 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, 2017 and 2016 are as follows: Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 Weighted average fair value per share $ 13.14 $ 12.00 $ 12.09 $ 10.69 Expected volatility 25% - 28 % 26% - 32 % 24% - 28 % 22% - 32 % Risk-free interest rate 1.2% - 1.3 % 0.4% - 0.7 % 0.7% - 1.3 % 0.4% - 0.8 % 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, 2017, and activity during the nine months ended September 30, 2017 are summarized below (in thousands, except weighted average exercise price and remaining contractual term): Shares Weighted Weighted Aggregate Options outstanding at January 1, 2017 315 $ 13.86 Options exercised (140 ) 12.22 Options outstanding at September 30, 2017 175 $ 15.18 1.32 $ 4,812 Options vested and expected to vest at September 30, 2017 175 $ 15.18 1.32 $ 4,812 Options exercisable at September 30, 2017 175 $ 15.18 1.32 $ 4,812 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 Non-vested Time-based Performance-based Market-based Total Shares Weighted Shares Weighted Shares Weighted Shares Weighted Non-vested 795 $ 43.79 1,265 $ 42.64 23 $ 33.16 2,083 $ 43.34 Granted 120 45.98 371 46.93 — — 491 46.70 Vested (417 ) 43.88 (276 ) 40.83 — — (693 ) 42.66 Forfeited (49 ) 43.72 (437 ) 41.29 — — (486 ) 41.53 Non-vested 449 $ 44.30 923 $ 45.55 23 $ 33.16 1,395 $ 45.49 Vested RSUs Performance-based RSUs that vested based on financial results are included in “Vested RSUs” in the table above 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, 2017 was $29.6 million. The aggregate intrinsic value at September 30, 2017 for RSUs expected to vest was $34.1 million and the remaining weighted average vesting period was 1.0 year. 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, 2017. RSUs expected to vest represent time-based RSUs unvested and outstanding at September 30, 2017, 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 stock options, market-based RSUs, and market-based stock options were not granted during the nine months ended September 30, 2017 and 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, 2017 and 2016 are as follows: Performance-based RSUs Short-term Long-term Nine months ended September 30, 2017 Grants Grant date fair value per share $ 47.23 $ 45.96 Service period (years) 1.0 2.0 - 3.0 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 Our performance-based RSUs generally vest when specified performance criteria are met based on bookings, revenue, cash provided by operating activities, non-GAAP non-GAAP non-GAAP Non-GAAP Non-GAAP 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. Market-based awards that were granted in prior periods vest when our average closing stock price exceeds defined multiples of the closing stock price for 90 consecutive trading days. If these multiples were not achieved by the expiration date, the awards are forfeited. The grant date fair value is being amortized over the average derived service period of the awards. The average derived service period and total fair value were determined using a Monte Carlo valuation model based on our assumptions, which include a risk-free interest rate and implied volatility. 2017 Equity Incentive Plan Our stockholders approved the 2017 Equity Incentive Plan (“2017 Plan”) on June 7, 2017, which includes: • 1.2 million shares of our common stock reserved for issuance pursuant to such plan; • 1,593,660 common stock shares that were available for future grants under the 2009 Equity Incentive Award Plan (“Prior Plan”) immediately prior to termination of authority to grant new awards under the Prior Plan on June 7, 2017; • shares subject to stock options granted under the Prior Plan and outstanding as of June 7, 2017, which expire, or for any reason are cancelled or terminated, after that date without being exercised; and • shares subject to restricted stock unit awards granted under the Prior Plan that are outstanding and unvested as of June 7, 2017 which are forfeited, terminated, cancelled, or otherwise reacquired after that date without having become vested. No additional grants will be made under the Prior Plan. The 2017 Plan replaces the Prior Plan and will be used to help attract, retain and motivate employees, consultants, and directors.

Equity [Abstract]
Common Stock Repurchase Programs	13. Common Stock Repurchase Programs On November 9, 2015, the board of directors approved the repurchase of $150 million of outstanding common stock commencing January 1, 2016. On September 11, 2017, the board of directors approved the repurchase of an additional $125 million for our share repurchase program commencing September 11, 2017. At that time, $28.8 million remained available for repurchase under the 2015 authorization. The 2017 authorization thereby increased the repurchase authorization to $153.8 million of our common stock. This authorization expires December 31, 2018. Under this publicly announced plan, we repurchased 0.3 and 1.0 million shares for an aggregate purchase price of $12.5 and $47.0 million during the three and nine months ended September 30, 2017, respectively. We repurchased 0.4 and 1.4 million shares for an aggregate purchase price of $18.0 and $57.7 million during the nine months ended September 30, 2016, respectively. 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 $3.1 and $10.0 million during the three and nine months ended September 30, 2017, respectively, and 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. 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 repurchase program is limited by SEC regulations and is subject to compliance with our insider trading policy.

Our financing receivables of $30.7 and $31.0 million consisted of $17.6 and $17.8 million of sales-type lease receivables, included within other current assets and other assets at September 30, 2017 and December 31, 2016, respectively, and $13.1 and $13.2 million of trade receivables having an original contractual maturity in excess of one year, included within accounts receivable, net of allowance, at September 30, 2017 and December 31, 2016, respectively. The trade receivables of $13.1 and $13.2 million having an original total contractual maturity in excess of one year at September 30, 2017 and December 31, 2016, include $5.7 and $7.1 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, 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 $5.9 and $15.3 million during the three and nine months ended September 30, 2017, respectively, and $19.8 million during the year ended December 31, 2016, 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 $2.1 and $3.1 million during the three and nine months ended September 30, 2017, respectively, and $3.5 million during the year ended December 31, 2016, 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.

Subsequent Events	15. Subsequent Events Acquisition of Escada On October 1, 2017, we acquired privately held Escada Innovations Limited, a private limited company incorporated in England and Wales which is headquartered in Hull, East Yorkshire, United Kingdom, and Escada Systems, Inc., a Delaware corporation headquartered in Decatur, Georgia (collectively, “Escada”), for approximately $11.3 million in cash consideration, plus a potential future cash earnout of $4.8 million contingent on achieving certain performance targets. This acquisition will be accounted for as a purchase business combination and, accordingly, the total purchase price will be allocated to the tangible and intangible assets acquired and liabilities assumed based on their respective fair values on October 1, 2017. Escada provides corrugator control systems for the corrugated packaging market, which provides comprehensive control and traceability for the entire corrugation process. Escada will be integrated into the Productivity Software operating segment. Xeikon Agreement On November 1, 2017 (“Effective Date”), we entered into a Support Services and License Agreement (“Agreement”) with Xeikon, N.V. (“Xeikon”), which is a division of the Flint Group headquartered in Luxembourg. Pursuant to the Agreement, we will provide Xeikon access to the Jetrion customer list. Access to the customer list will enable Xeikon to assume the relationship with the third-party outsourcing company that manufactures Jetrion printers for us and resell the printers to our current customer base. Xeikon will purchase Jetrion ink exclusively from us and resell to both our current customer base as well as new Xeikon inkjet customers. Also, we will cease sales of Jetrion products for four years after the Effective Date. We will receive cash consideration of $2 million in the first year followed by three annual volume-based payments that are tied to Xeikon’s ink purchases from us.

Upon evaluation, we believe the key changes in the guidance that impact our revenue recognition relate to the timing of revenue recognition and allocation of contract revenue between services and software licenses. The requirement to defer incremental contract acquisition costs (e.g., commissions) and recognize them over the contract period or expected customer life will result in the recognition of a deferred charge on our balance sheet. We are assessing the impact on our consolidated financial statements, systems, and controls upon adoption. Principal vs Agent. 2016-08, Several 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.

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.
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 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. non-U.S. 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 respective reporting entity’s functional currency, and the settlement of intercompany balances denominated in currencies other than their functional currency). Under our master netting agreements with our foreign currency derivative counterparties, we are allowed to net transactions of the same currency with a single net amount payable by one party to the other. The derivatives held by us are not subject to any credit contingent features negotiated with these counterparties. We are not required to pledge cash collateral related to these foreign currency derivative contracts. We do not believe there is significant risk of loss from non-performance Cash Flow Hedges Foreign currency derivative contracts with notional amounts of $3.8 million and $3.2 million have been designated as cash flow hedges of our Indian rupee operating expense exposure at September 30, 2017 and December 31, 2016, respectively. 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 $188.0 and $158.7 million are used to hedge foreign currency balance sheet exposures at September 30, 2017 and December 31, 2016, 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

Recent Accounting Pronouncements	Hedge Accounting. 2017-12, Our foreign currency derivative contracts include notional amounts of $3.8 million that have been designated as cash flow hedges of our Indian rupee operating expense exposure at September 30, 2017. Under current guidance, changes in the fair value of the effective portion of these contracts are reported as a component of other comprehensive income (“OCI”) and reclassified to operating expense in the periods of payment of the hedged cash flows. The ineffective portion is recognized as a component of interest income and other income, net. Under the new guidance, the entire change in the fair value of hedging instruments designated as cash flow hedges that are included in the assessment of hedge effectiveness will be recorded in OCI. Those amounts are reclassified to earnings in the periods of payment in the same income statement line item as the hedged operating expenses. Upon adoption, a cumulative-effect adjustment will be required to charge the ineffective portion of derivative contracts designated as cash flow hedges existing at the date of adoption to accumulated OCI with a corresponding adjustment to the retained earnings as of the beginning of the fiscal year of the adoption. The new guidance continues to require an initial prospective quantitative hedge effectiveness assessment unless the hedging relationship qualifies for the critical-terms-match method or facts and circumstances method, which permit an assumption of perfect hedge effectiveness. After the initial quantitative assessment, the new guidance permits a qualitative ongoing effectiveness assessment for certain hedges if we can reasonably support an expectation of high effectiveness throughout the term of the hedge. The new guidance also requires additional disclosure related to the effect on the income statement of cash flow hedges. ASU 2017-12

Support services and license agreement, description			On November 1, 2017 (“Effective Date”), we entered into a Support Services and License Agreement (“Agreement”) with Xeikon, N.V. (“Xeikon”), which is a division of the Flint Group headquartered in Luxembourg. Pursuant to the Agreement, we will provide Xeikon access to the Jetrion customer list. Access to the customer list will enable Xeikon to assume the relationship with the third-party outsourcing company that manufactures Jetrion printers for us and resell the printers to our current customer base. Xeikon will purchase Jetrion ink exclusively from us and resell to both our current customer base as well as new Xeikon inkjet customers. Also, we will cease sales of Jetrion products for four years after the Effective Date. We will receive cash consideration of $2 million in the first year followed by three annual volume-based payments that are tied to Xeikon’s ink purchases from us.
