The Company and Summary of Significant Accounting Principles | 1. The Company and Summary of Significant Accounting Principles Synacor, Inc., together with its consolidated subsidiaries (collectively, the “Company” or “Synacor”), is the trusted technology development, multiplatform services and revenue partner for video, internet and communications providers, device manufacturers, governments and enterprises. Synacor enables its customers to provide their consumers engaging, multiscreen experiences and advertising to their consumers that require scale, actionable data and sophisticated implementation. Basis of Presentation — The interim unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of the Company’s management, the interim unaudited condensed consolidated financial statements include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position for the periods presented. These interim unaudited condensed consolidated financial statements are not necessarily indicative of the results expected for the full fiscal year or for any subsequent period. The accompanying condensed consolidated balance sheet as of December 31, 2016 was derived from the audited financial statements as of that date, but does not include all the information and footnotes required by U.S. GAAP. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Accounting Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Such estimates primarily relate to unsettled transactions and events as of the date of the financial statements. Accordingly, actual results may differ from estimated amounts. Concentrations of Risk — As of March 31, 2017, two customers had outstanding balances due to the Company of 10% or more of the Company’s accounts receivable. These two customers, Google and an advertising customer, had outstanding balances amounting to 14% and 10%, respectively, of the Company’s total accounts receivable at March 31, 2017. As of December 31, 2016, the Company had no customers whose outstanding balance due to the Company equaled or exceeded 10% or more of the Company’s total accounts receivable. For the three months ended March 31, 2017 and 2016, the Company had one customer, Google, which accounted for 10% or more of the Company’s revenue. Revenue from Google represented 11% and 17% of the Company’s total revenue for the three months ended March 31, 2017 and 2016, respectively. For the three months ended March 31, 2017 and 2016, the following customers received revenue-share payments equal to or exceeding 10% of the Company’s cost of revenue. Cost of Revenue Three Months Ended March 31, 2017 2016 Customer A 19 % 29 % Customer B * 12 % * - Less than 10% Recent Accounting Pronouncements — Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 (ASU 2014-09), Revenue from Contracts with Customers Revenue from Contracts with Customers: Deferral of the Effective Date Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, The Company is currently in the process of assessing the financial impact of adopting these ASUs and the methods of adoption. The Company currently recognizes subscription revenue from its Email/Collaboration contracts, which is included within recurring and fee-based revenue, over the life of the contracts (which are typically six months or longer). The Company has tentatively concluded that it is likely that this new guidance will require it to recognize a portion of the revenue from those contracts upon delivery, at the inception of the contracts, which would have the effect of accelerating recognition of revenue on such contracts, and may have a material impact on the Company’s consolidated financial statements. The standard will be effective for the Company beginning January 1, 2018. The Company anticipates adopting the standard as of its effective date of January 1, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The Company has not yet determined which transition method it will use.
