Item 2.02. Results of Operations and Financial Condition.

As disclosed during the earnings call of Electronics For Imaging, Inc. (the “Company” or EFI) held on September 11, 2017, the Company expected that the review of our revenue recognition practices would require the expenditure of significant management time and that we would incur significant accounting, legal, and other expenses totaling approximately $5 million during the three and nine months ended September 30, 2017, which would impact our net income calculated in accordance with generally accepted accounting practices (“GAAP Net Income”) for those periods. The Company’s Board of Directors requested that management refrain from paying certain fees related to the review so that those fees could be considered further. As a result, the Company did not accrue approximately $1.2 million of fees, which it has since determined should have been accrued, and which were not included in our third quarter earnings release dated October 26, 2017 in which the Company reported GAAP Net Income of $1.9 million and $9.4 million, respectively, for the three and nine months ended September 30, 2017. The Company has since determined that it incurred accounting, legal and other expenses related to the review of our revenue recognition practices of $4.7 million for the three and nine months ended September 30, 2017. The Company’s GAAP net income for the three and nine months ended September 30, 2017 was $1.1 million and $8.7 million, respectively, rather than $1.9 million and $9.4 million, respectively, as previously reported. Earnings per share calculated in accordance with generally accepted accounting principles (“GAAP EPS”) was $0.02 and $0.18 per diluted common share, respectively, rather than $0.04 and $0.20 for the three and nine months ended September 30, 2017, respectively, as previously reported. As previously reported, non-GAAP net income was unchanged at $22.7 million and $74.0 million, respectively, and non-GAAP EPS was unchanged at $0.48 and $1.57, respectively, for the three and nine months ended September 30, 2017.

The information provided pursuant to this Item 2.02 is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities under that Section and shall not be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act.

Appendix

Reconciliation of GAAP to Non-GAAP EPS

Reconciliation of GAAP to Non-GAAP Gross Margin

Reconciliation of GAAP to Non-GAAP Operating Income

Reconciliation of GAAP to Non-GAAP OPEX

About our Non-GAAP Financial Measures and Adjustments Use of Non-GAAP Financial Information To supplement our condensed consolidated financial results prepared in accordance with GAAP, we use non-GAAP measures of operating income, net income, and earnings per diluted share that are GAAP operating income, GAAP net income, GAAP operating expenses, GAAP gross margin, GAAP operating profit , GAAP earnings, operating expenses, gross margin, and operating profit per diluted share adjusted to exclude certain cost, expenses, and gains. We believe that the presentation of non-GAAP operating income, non-GAAP net income, and non-GAAP earnings per diluted share provides important supplemental information regarding non-cash expenses and significant items that we believe are important to understanding financial and business trends relating to our financial condition and results of operations. Non-GAAP operating income, non-GAAP net income, and non-GAAP earnings per diluted share are among the primary indicators used by management as a basis for planning and forecasting future periods and by management and our Board of Directors to determine whether our operating performance has met specified targets and thresholds. Management uses non-GAAP operating income, non-GAAP net income, and non-GAAP earnings per diluted share when evaluating operating performance because it believes the exclusion of the items described below, for which the amounts and/or timing may vary significantly depending on our activities and other factors, facilitates comparability of our operating performance from period to period. We have chosen to provide this information to investors so they can analyze our operating results in the same way that management does and use this information in their assessment of our business and the valuation of our Company. Use and Economic Substance of Non-GAAP Financial Measures We compute non-GAAP operating income, non-GAAP net income, and non-GAAP earnings per diluted share by adjusting GAAP operating income, GAAP net income, and GAAP earnings per diluted share to remove the impact of amortization of acquisition-related intangibles, stock-based compensation expense, restructuring and other expenses, acquisition-related transaction expenses, costs to integrate such acquisitions into our business, incremental cost of revenue due to the fair value adjustment to inventories acquired in business combinations, changes in the fair value of contingent consideration, revenue recognition review costs and litigation settlement charges, and non-cash interest expense related to our 0.75% convertible senior notes (“Notes”). We use a constant non-GAAP tax rate of 19%, which we believe reflects the long term average tax rate based on our international structure and geographic distribution of revenue and profit. Ex-Currency.  To better understand trends in our business, we believe it is helpful to adjust our statement of operations to exclude the impact of year-over-year changes in the translation of foreign currencies into U.S. dollars. This is a non-GAAP measure that is calculated by adjusting revenue, non-GAAP operating income, and non-GAAP net income by using historical exchange rates in effect during the comparable prior year period and removing the balance sheet currency remeasurement impact from interest income and other expense, net, including removal of any hedging gains and losses. We refer to these adjustments as “ex-currency.” Management believes the ex-currency measures provide investors with an additional perspective on year-over-year financial trends and enables investors to analyze our operating results in the same way management does. The year-over-year currency impact can be determined as the difference between year-over-year actual growth rates and year-over-year ex-currency growth rates. These excluded items are described below: Inventory acquired in the acquisition of FreeFlow print server business from Xerox Corporation is required to be recorded at fair value rather than historical cost in accordance with ASC 805. The fair value of FreeFlow print server inventory reflects the manufacturing cost plus a portion of the expected gross profit. We have adjusted our cost of revenue to reflect the expected gross profit that was included in the inventory valuation under ASC 805. We believe this adjustment is useful to investors to understand the gross profit trends of our ongoing business. Intangible assets acquired to date are being amortized on a straight-line basis. Stock-based compensation expense of $22.5 and $29.7 million during the nine months ended September 30, 2017 and 2016, respectively, consists of $22.5 and $26.9 million of stock-based compensation expense recognized in accordance with ASC 718, Stock Compensation, and the non-cash settlement of $2.8 million of vacation liabilities settled through the issuance of RSUs during the nine months ended September 30, 2016, which is not included in the GAAP presentation of our stock-based compensation expense.

About our Non-GAAP Financial Measures and Adjustments (continued) Restructuring and other expenses consist of: Restructuring charges incurred as we consolidate the number and size of our facilities and, as a result, reduce the size of our workforce. Expenses incurred to integrate businesses acquired of $0.2 and $1.0 million for the three and six months ended September 30, 2017, respectively, and $0.6 and $1.5 million for the three and six months ended September 30, 2016 respectively. Acquisition-related transaction costs associated with businesses acquired during the periods reported and anticipated transactions of $0.6 and $1.8 million for the three and six months ended September 30, 2017, respectively, and $0.4 and $1.7 million for the three and six months ended September 30, 2016, respectively. Changes in fair value of contingent consideration. Our management determined that we should analyze the total return provided by the investment when evaluating operating results of an acquired entity. The total return consists of operating profit generated from the acquired entity compared to the purchase price paid, including the final amounts paid for contingent consideration without considering any post-acquisition adjustments related to changes in the fair value of the contingent consideration. Because our management believes the final purchase price paid for the acquisition reflects the accounting value assigned to both contingent consideration and to the intangible assets, we exclude the GAAP impact of any adjustments to the fair value of acquisition-related contingent consideration from the operating results of an acquisition in subsequent periods, including the related foreign exchange fluctuation impact. We believe this approach is useful in understanding the long-term return provided by our acquisitions and that investors benefit from a supplemental non-GAAP financial measure that excludes the impact of this adjustment. Non-cash interest expense on our Notes. Our Notes may be settled in cash on conversion. We are required to separately account for the liability (debt) and equity (conversion option) components of the Notes in a manner that reflects our non-convertible debt borrowing rate. Accordingly, for GAAP purposes, we are required to amortize a debt discount equal to the fair value of the conversion option as interest expense on our $345 million of 0.75% convertible senior notes that were issued in a private placement in September 2014 over the term of the Notes. Revenue recognition costs and Litigation settlements. As described in “Item 9A, Controls and Procedures” of our annual report on Form 10-K, for the year ended December 31, 2016, as amended, our management concluded that we had material weaknesses in our internal control over financial reporting as of December 31, 2016 related to revenue recognition practices and therefore did not maintain effective internal control over financial reporting or effective disclosure controls and procedures, both of which are requirements of the Securities Exchange Act of 1934, as of that date. The review of our revenue recognition practices has required that we expend significant management time and incur significant accounting, legal, and other expenses totaling $4.7 million during the three and nine months ended September 30, 2017, and we expect to incur additional costs in the future periods. We settled or accrued reserves related to several litigation claims of $0.1 and $0.4 million for the three and nine months ended September 30, 2017, respectively, and $0.1 and $0.9 million during the three and nine months ended September 30, 2016, respectively. Tax effect of non-GAAP adjustments. We use a constant non-GAAP tax rate of 19%, which we believe reflects the long term average tax rate based on our international structure and geographic distribution of revenue and profit. The long-term average tax rate is calculated in accordance with the principles of ASC 740, Income Taxes, to estimate the non-GAAP income tax provision in each jurisdiction in which we operate after excluding the tax effect of the non-GAAP items described above. Usefulness of Non-GAAP Financial Information to Investors Our non-GAAP measures are not in accordance with or an alternative to GAAP and may be materially different from other non-GAAP measures, including similarly titled non-GAAP measures, used by other companies. The presentation of this additional information should not be considered in isolation from, as a substitute for, or superior to, net income or earnings per diluted share prepared in accordance with GAAP. Non-GAAP financial measures have limitations in that they do not reflect certain items that may have a material impact upon our reported financial results. We expect to continue to incur expenses of a nature similar to the non-GAAP adjustments described above, and exclusion of these items from our non-GAAP financial metrics should not be construed as an inference that these costs are unusual, infrequent, or non-recurring.
