Item 1.BusinessOverviewWe have created a comprehensive cloud-based software platform designed to transform and modernize accounting and finance operationsfor organizations of all types and sizes. Our secure, scalable platform supports critical accounting processes such as the financial close, accountreconciliations, intercompany accounting, and controls assurance. By introducing software to automate these processes and to enable them tofunction continuously, we empower our customers to improve the integrity of their financial reporting, increase efficiency in their accounting andfinance processes and enhance real-time visibility into their results and operations.Critical accounting and finance processes underlie the integrity of an organization’s financial reports. The lack of effective accounting andfinance tools can result in inefficient and cumbersome processes and, in some cases, accounting errors, restatements and write-offs, as well asmaterial weaknesses and significant deficiencies. Traditional enterprise resource planning, or ERP, systems do not generally provide effectivesolutions for processes handled outside of an organization’s general ledger, such as balance sheet account reconciliation, intercompanytransaction accounting and the broader financial close process. Many organizations also use multiple ERPs and other financial systems without aplatform to efficiently integrate them. As a result, to manage these tasks, organizations rely on spreadsheets and other error-prone and labor-intensive processes that are unsuited for the increasing regulatory complexity and transaction volumes encountered by many modernbusinesses. We believe that we are creating a new category of powerful cloud-based software that is capable of automating and streamliningaccounting and finance operations, in a manner that complements and supports traditional ERP systems. We believe our customers benefit fromcost savings through improvements in process management and staff productivity, in addition to managing a faster financial close.3 Our mission is to transform how accounting and finance departments operate. Our approach modernizes what historically has been donethrough batch processing and manual controls typically applied only during the month, quarter or year-end financial close, and delivers dynamicworkflows embedded within a real-time, highly automated framework, a process we refer to as “continuous accounting.” It also enables up-to-dateanalytics, provides industry-benchmarked metrics and is designed to help customers run more efficiently while achieving greater accuracy, controland transparency. We believe the need for our software has been driven by growing business and information technology complexities,transaction volumes and expanding regulatory requirements. Our software integrates with, and obtains data from, more than 30 different ERPsystems, including NetSuite, Oracle, SAP, and Workday, as well as many other financial systems and applications such as bank accounts, sub-ledgers and in-house databases.We believe that we have a leading position in the enhanced financial controls and automation market because we were one of the firstcompanies to bring software with this functionality to market and we have a limited number of competitors. The 2017 Gartner Report, “MagicQuadrant for Cloud Financial Corporate Performance Management Solutions,” or the “Gartner Report,” identified us as a Leader in the MagicQuadrant for Cloud Financial Corporate Performance Management Solutions for our completeness of vision and ability to execute.At December 31, 2017, we had approximately 2,200 customers with approximately 196,000 users in over 150 countries exclusive of ouracquisition of Runbook Company B.V., a Netherlands-based provider of financial close automation software and integration solutions for SAPcustomers, (“Runbook”) on August 31, 2016 (the “Runbook Acquisition”). We continue to build strategic relationships with technology vendors,professional services firms, business process outsourcers and resellers.We are a holding company and conduct our operations through our wholly-owned subsidiary, BlackLine Systems, Inc. (“BlackLineSystems”). BlackLine Systems funded its business with investments from our founder and cash flows from operations until September 3, 2013, weacquired BlackLine Systems, and Silver Lake Sumeru and Iconiq acquired a controlling interest in us, which we refer to as the “2013 Acquisition”The 2013 Acquisition was accounted for as a business combination under GAAP, and resulted in a change in accounting basis as of the date ofthe 2013 Acquisition.Our platform consists of eight core cloud-based products, including Transaction Matching, Account Reconciliations, Consolidation IntegrityManager, Daily Reconciliations, Journal Entry, Variance Analysis, Task Management, and Insights. Customers typically purchase these productsin packages that we refer to as solutions, but they have the option to purchase these products individually. Current solutions include BalanceSheet Integrity, Close Process Management, Accounting Process Automation, Finance Transformation, Intercompany Hub, and Smart Close.We sell our solutions primarily through our direct sales force, which leverages our relationships with technology vendors, professionalservices firms and business process outsourcers. In particular, we have a strategic relationship with SAP. Our solutions are SAP endorsedbusiness solutions that integrate with SAP’s ERP solutions.We target our sales and marketing efforts at both enterprise and mid-market businesses. We define the enterprise market as companieswith greater than $500 million in annual revenue, and we define mid-market as companies with between $50 and $500 million in annual revenue.For the year ended December 31, 2017, sales to enterprise and mid-market customers represented 84% and 16% of our revenues, respectively.Additionally, we target our efforts at both new customers and existing customers. Existing customers may renew their subscriptions and broadenthe deployment of our platform across their organizations by increasing the number of users accessing our platform or by adding additionalproducts.We will adopt the Accounting Standards Codification No. 606, Revenue from Contracts with Customers (“ASC 606”), in the first quarter of2018 using the retrospective method, which will result in the retrospective adjustment of our consolidated financial statements for the years endedDecember 31, 2017 and 2016. The adoption of this new standard will impact how we account for certain of our revenue arrangements and for salescommissions. See “Significant Accounting Policies - Recent accounting pronouncements” in Note 2 of the accompanying notes to ourconsolidated financial statements for additional information.4 Industry BackgroundAccounting is a Universal Mission-Critical FunctionOrganizations need reliable financial information to plan and execute business initiatives, measure operational progress and satisfyregulatory and financial obligations. For each period-end, enterprise accounting functions typically record, process, reconcile, consolidate, andreport financial transactions that are consolidated into useable financial information. These activities typically support other core businessfunctions such as payroll, treasury, procure-to-pay, and order-to-cash processes. Traditionally, many accounting processes, such as balancesheet account reconciliation, intercompany transaction accounting and the broader financial close calendar, are managed and tracked withspreadsheets that are manually reconciled on a periodic basis, and which are often labor-intensive, inefficient and error-prone. The risks ofemploying traditional methods include lapses in regulatory compliance, damage to brand and public image, and negative impacts on financialhealth and transparency.Modern Business is Increasingly ComplexOrganizations of all sizes are operating in an increasingly global, complex and fast-moving business environment that presents significantchallenges to the performance of the accounting and finance functions. Accountants must process and verify transactions that occur both withinand across international borders, involve multiple currencies and require compliance with varying legal, regulatory and tax frameworks. Thistransactional complexity is exacerbated by other factors typical of global business, such as distance, language barriers and differing timezones. In addition, modern enterprises generate massive amounts of transaction data. It is common for organizations to have thousands ofdifferent accounts—potentially comprising billions of records—and to use numerous different financial and operational systems to store thatdata. Furthermore, companies employ increasingly sophisticated corporate structures that often require accountants to reconcile accounts acrossvarious business units and geographies. We believe that the complexity of modern corporate structures and transactions, combined with mountingtransaction volumes and a fragmented information technology landscape, creates a significant need for increased automation, efficiency andvisibility in accounting and finance.The Risk of Regulatory Non-Compliance is SignificantPublic accounting follows a variety of rules and standards for the processing, recognition and reporting of transactions. These standards,such as generally accepted accounting principles, or GAAP, and International Financial Reporting Standards, or IFRS, are highly specific, applydifferently across industries and geographies and, in some cases, provide conflicting guidance. More specific frameworks such as the Sarbanes-Oxley Act of 2002 govern internal controls, disclosure management and audit conduct. Some highly-regulated industries, including financialservices, gaming and insurance, have additional specific regulatory requirements. In addition, accounting standards periodically change, such asthe revenue recognition accounting standard issued by the Financial Accounting Standards Board, or the FASB in 2014, which must be adopted bypublic companies in the first quarter of 2018 and has required an overhaul of many public accounting systems and practices. The resulting tangleof stringent, changing and sometimes conflicting regulations typically requires that organizations maintain more than one set of records, investheavily in implementing and monitoring internal controls, and undergo expensive and time-consuming audits.Incorrect financial information can have severe repercussions. A single restatement can cost millions of dollars in forensic accounting andaudit fees, lead to significant remediation expenses, generate investor lawsuits, and seriously damage an enterprise’s reputation. A materialweakness can also trigger noncompliance with debt covenants and damage an organization’s credit-worthiness. The Securities and ExchangeCommission, or SEC, has also proposed new rules that will require companies to “claw back” incentive-based executive compensation as a resultof an accounting restatement. According to the Center for Audit Quality, from 2003 to 2012, 10,479 accounting restatements were reported by SECreporting companies, including 4,246 restatements requiring reissuance of the affected financial statements, and there was a demonstratednegative near-term effect on the public market price of securities of many companies making such restatements.5 Companies Lack Real-Time, Actionable Data from Their Accounting DepartmentsAs complexity, transaction volume and regulatory scrutiny increase, management teams often find themselves without clear and immediateinsight into their accounting and finance processes and results. In most cases, the accounting department’s work is done within desktopapplications or with the use of spreadsheets, leaving management with an incomplete view of their progress in closing, consolidating and reportingeach period. By the time data is manually compiled, it is often days or weeks out-of-date, limiting the ability to effectively track and analyzefluctuations and trends, detailed metrics on individual and team performance, and transaction risk profiles in a timely manner.Such lack of visibility limits the ability of accounting managers to influence ongoing accounting operations. Instead, they are often relegatedto conducting quality control measures after a process is completed. Important decisions may be made by less experienced employees and costlyerrors, such as unreconciled balances or unapproved fund transfers, may go undetected. In addition, the discipline of accounting frequently lacksestablished metrics by which to gauge performance.Accounting Professionals Face Compressed Deadlines and a Heightened Expectation of AccuracyMany organizations, and public companies in particular, have adopted a practice of reporting financial information by a fixed date followingtheir quarter close. Given limited resources, an accelerated timetable can put immense pressure on a company’s accounting function. Accountingprofessionals are expected not only to address business and regulatory challenges but also to achieve completeness and accuracy of operatingresults to ensure financial integrity. Given these challenges and deadlines, accountants are often forced to leave certain accounts andtransactions unreconciled, which can dramatically increase risk and create situations of concern for controllers, chief financial officers and auditcommittee members.Traditional Accounting Processes and Tools are InefficientThe processes and software solutions traditionally employed by accountants, such as general ledgers and ERP systems, do not provideeffective solutions for critical, non-general ledger accounting and finance processes such as balance sheet account reconciliation, intercompanytransaction accounting and the overall management of the entire financial close process. Most core accounting and finance systems are designedas batch transaction repositories without the ability to consume and process continuous streams of data. In addition, most organizations usemultiple ERPs and many other financial systems across their IT environments. Traditionally available accounting tools are inflexible, expensive toconfigure and maintain, and do not scale easily. As a result, we are addressing a clear need for new scalable accounting and finance tools thatcan consume data from a variety of sources, process it quickly with embedded business logic, provide a collaborative workspace for accountants,and then store information within a data warehouse or ERP system. Furthermore, accounting processes themselves have not evolved over timeand instead remain focused on producing financial information only after period-end, ignoring the growing demand for a more streamlined,continuous approach to accounting.The BlackLine SolutionWe provide a powerful cloud-based software platform designed to automate and streamline accounting and finance operations. The keyelements of our solutions include:Comprehensive PlatformWe offer an integrated suite of applications that delivers a broad range of capabilities that would otherwise require the purchase and use ofmultiple products to support critical accounting processes such as the financial close, account reconciliations, intercompany accounting, andcontrols assurance. Our platform consists of eight core cloud-based products, including Transaction Matching, Account Reconciliations,Consolidation Integrity Manager, Daily Reconciliations, Journal Entry, Variance Analysis, Task Management and Insights. Customers typicallypurchase these products in packages that we refer to as solutions, but they have the option to purchase these products individually. Currentsolutions include Balance Sheet Integrity, Close Process Management, Accounting Process Automation, Finance Transformation, IntercompanyHub, and Smart Close.The technology underpinning our platform includes a comprehensive base of accounting-specific business logic and rules engines, whichenable our customers to implement continuous accounting.6 Enterprise IntegrationOur platform provides simple, secure and automated tools and integrations to transfer data to and from a range of enterprise-wide processesand systems, including ERPs, financial systems and in-house databases, and other custom applications and data. Our platform integrates withover 30 ERP systems, including NetSuite, Oracle, SAP, and Workday. In addition, for companies with multiple systems and complex needs, wecan connect with any number of general ledger systems simultaneously, resolving many of the issues associated with consolidating data acrosssystems.IndependenceOur platform is not dependent on any single operating system and works with most major ERP systems our customers may use. Our cross-system functionality allows us to reach a broader group of customers. We are also able to focus on and innovate for the needs of the customersirrespective of updates or changes in their existing systems. We believe this independence provides us with a competitive advantage in theindustry over traditional methods.Ease of UseOur platform is designed by accountants, for accountants, to be intuitive and easy to use.

Through a history and culture of thoughtleadership, we have created a new category of powerful software that automates and streamlines antiquated, manual accounting processes tobetter meet our clients’ diverse and rapidly changing needs, and we continue to focus on providing advanced solutions to time and labor intensiveaccounting practices. Examples of recent innovations include the launches of our Intercompany Hub solution, which is designed to manage allintercompany transactions through one centralized, cloud-based system, and the launch of our Insights solution, which provides real-timeperformance measures and a benchmarking dashboard.SecurityThe robust security features embedded in our platform are designed to meet or exceed both industry standards and the stringent securityrequirements of our customers. We engage independent security auditors to assess the effectiveness of our comprehensive information securityprogram consisting of risk-driven policies and procedures.Key BenefitsOur platform is designed to provide the following benefits to our customers:Flexibility and scalabilityOur unified cloud platform is designed for modern business environments and has broad applicability across large and small organizations inalmost any industry. The platform supports complex corporate structures, provides integration across all core financial systems, manages multiplecurrencies and languages, and scales to support high transaction volumes.Embedded controls and workflowOur platform was designed for the complex global regulatory environment. Our platform embeds key controls within standardized, repeatableand well-documented workflows, which are designed to result in substantially reduced risk of non-compliance or negative audit findings, greatertolerance for regulatory complexity and increased confidence in financial reports.7 Real-time visibilityWe provide users with real-time visibility into the status, progress and quality of their accounting processes. With configurable dashboards,user-defined reporting and the ability to drill down to individual reconciliations, journals and tasks, users can track open items, identify bottleneckswithin a process or intervene to prevent mistakes.Automation and efficiencyOur platform can ingest data from a variety of sources, including ERP systems and other data repositories, and apply powerful, rules-drivenautomation to reconciliations, journals and transactions. This streamlines accounting processes, minimizes manual data entry and improvesindividual productivity to help ensure that accounting processes are completed on time. As a result, this automation allows users to focus onvalue-added activities instead of process management.Continuous processingOur platform helps organizations embed quality control, compliance and financial integrity into their day-to-day processes rather than rely onthe traditional process of validating financial information at the end of each period. Activities such as account reconciliation and variance analysiscan be performed in real-time, thus reducing the risk of errors and creating a more agile accounting environment.Our Growth StrategyWe intend to continue investing in a number of growth initiatives to provide our customers with advanced solutions and to address andexpand our market opportunity. Our principal growth strategies include the following:Continue to Innovate and Expand Our PlatformOur ability to develop new, market-leading applications and functionalities is integral to our success.

Examples of recent innovations includethe launch of our Intercompany Hub solution, which is designed to manage all intercompany transactions through one centralized, cloud-basedsystem and the launch of our Insights solution, which provides real-time performance measures and a benchmarking dashboard.Enhance Our Leadership Position in the Enterprise Market and Mid-Market Customer BaseWe believe we have a leading position in the enhanced financial controls and automation market with both enterprise market and mid-marketcustomers, and we were recognized as a Leader by the Gartner Report in the 2017 Magic Quadrant for Cloud Financial Corporate PerformanceManagement Solutions for our completeness of vision and ability to execute. We had more than 2,200 customers across a variety of industriesand geographies at December 31, 2017 exclusive of on-premise software. Our customers include some of the largest multi-national enterprises, aswell as leading medium and small businesses around the world. We intend to leverage our brand, history of innovation and customer focus tomaintain and grow our leadership position with enterprise market customers. We believe that mid-market businesses are particularly underservedand that our platform can help these businesses modernize their accounting and finance processes efficiently and effectively. We have maderecent investments to grow our mid-market sales team and plan to continue leveraging our network of resellers to grow our mid-market businessglobally.Increase Customer Spend through Expanded Usage and Adoption of Additional ProductsWe believe there is a significant opportunity to increase sales of our products within our existing customer base. We pursue a land-and-expand sales model to increase the use of our platform by selling additional solutions and features and increasing the number of users within ourcustomers’ organizations. Our pricing model is designed to allow us to capture additional revenue as our customers’ usage of our platform grows,providing us with an opportunity to increase the lifetime value of our customer relationships.8 Expand Our International Operations and Customer FootprintWe believe that we have a significant opportunity to expand the use of our cloud-based products outside the United States. We derivedapproximately 20%, 16%, and 14% of our revenues from sales outside the United States in the years ended December 31, 2017, 2016, and 2015,respectively, and we believe there are substantial opportunities to increase sales to customers outside of the U.S. In August 2016, we acquiredRunbook primarily to enhance our position as a leading provider of software solutions to automate the financial close process for SAP customersand secondarily it supports our European expansion strategy. We currently have users in over 150 countries, and our platform supports applicableinternational accounting standards, as well as 16 languages and all currencies specified by the International Organization for Standardization, orISO currencies. We have an established presence in Australia, Canada, England, France, Germany, Malaysia, Netherlands, Poland, Romania,Singapore, South Africa, and the United Kingdom, and we intend to invest in further expanding our footprint in these and other regions.Extend Our Customer Relationships and Distribution ChannelsWe have established strong strategic alliances with key industry participants to supplement marketing and delivery of our applications.These strategic alliances include agreements with technology vendors such as SAP and NetSuite, professional services firms such as Deloitte,Ernst & Young, and KPMG, and business process outsourcers, or BPOs, such as Cognizant, Genpact, and IBM.These relationships enable us to effectively market our solutions by offering a complementary suite of services to our customers. Inparticular, we offer our customers an integrated SAP-endorsed business solution through our relationship with SAP. We intend to continue tostrengthen and expand our existing relationships, seek new relationships and further expand our distribution channels to help us expand into newmarkets and increase our presence in existing markets.CustomersOur customers include multinational corporations, large domestic enterprises and mid-market companies across a broad array of industries.These businesses include publicly-listed entities and privately-owned enterprises, as well as non-profit entities. At December 31, 2017, we hadover 196,000 individual users in over 150 countries across more than 2,200 customers exclusive of on-premise software. We define a customer asan entity with an active subscription agreement as of the measurement date. In situations where an organization has multiple subsidiaries ordivisions, each entity that is invoiced as a separate entity is treated as a separate customer. However, where an existing customer requests itsinvoice be divided for the sole purpose of restructuring its internal billing arrangement without any incremental increase in revenue, such customercontinues to be treated as a single customer. For the years ended December 31, 2017, 2016, and 2015, sales to enterprise customers represented84%, 85%, and 86% of our revenues, respectively, while sales to mid-market customers represented 16%, 15%, and 14% of our revenues,respectively.Our customers operate in complex, diverse and often global information technology ecosystems with numerous general ledgers, sub-ledgers, treasury systems, and ERP systems from different vendors, including NetSuite, Oracle, SAP and Workday. Our platform is designed forand used by employees across the organization, including end users such as internal accounting employees, controllers and chief accountingofficers, as well as chief financial officers and other senior executives and external auditors.We have seen our customers benefit from improvements in the complete automation process and staff productivity, in addition to a fasterand more accurate financial close. Cost savings are achieved from the reconciliations of accounts, across approval and review roles, in processadministration, and in audit, storage and paper expenses.Products and ServicesOur platform consists of eight core cloud-based products, including Transaction Matching, Account Reconciliations, Consolidation IntegrityManager, Daily Reconciliations, Journal Entry, Variance Analysis, Task Management and Insights. Customers typically purchase these productsin packages that we refer to as solutions, but they have the option to purchase these products individually. Current solutions include BalanceSheet Integrity, Close Process Management, Accounting Process Automation, Finance Transformation, Intercompany Hub, and Smart Close.9 Reconciliation ManagementThe process of verifying and validating transactions, balances and consolidated financial results is referred to as account reconciliation. OurReconciliation Management solution provides a framework for the reconciliation process, allowing users to build integrity checks and automationinto the entire end-to-end work flow. The solution includes: •Account Reconciliations provides a centralized workspace from which users can collaborate to complete account reconciliations.Features include standardized templates, workflows for review and approval, linkage to policies and procedures, and integratedstorage of supporting documentation. The product automates otherwise manual activities in the reconciliation process, significantlyreducing time and effort and increasing productivity. It also enhances internal controls by facilitating the appropriate segregation ofduties, simplifying reconciliation audits and adding transparency and visibility to the reconciliation process. •Transaction Matching analyzes and reconciles high volumes of individual transactions from different sources of data based uponuser-configured logic. Our rules engine automatically identifies exceptions, errors, missing data, and variances within massive datasets. The matching engine processes millions of records per minute, can be used with any type of data and allows customers toreconcile transactions in real-time. •Consolidation Integrity Manager manages the automated system-to-system tie-out process that occurs during the consolidationphase of the financial close. Companies with multiple ERPs utilize a consolidation system to produce their consolidated financialresults. Because these systems contain and produce information that changes continually and requires constant adjustments, a finaltie-out that is typically handled manually in a spreadsheet is necessary prior to publishing results. This product automates the tie-outprocess, aggregating balances from dozens or hundreds of different systems and allowing users to identify exceptions and createadjustments quickly. •Daily Reconciliations narrows the scope of a reconciliation to a single day’s transactions or balance detail. Users can then performtheir analysis in minutes per day, rather than attempting to review an entire month’s worth of activity in a limited time during theperiod-end close. Some industries, such as banking, require that organizations track the creation and certification of dailyreconciliations. Daily reconciliations are a prime example of continuous accounting in action.Financial Close ManagementThe collection of processes by which organizations reconcile, consolidate and report on their financial information at the end of each periodis referred to as the financial close. Our Financial Close Management solution allows customers to manage the key steps within the close,applying automation where possible, and ensure that tasks are properly completed and reviewed. This solution includes the components of theReconciliation Management solution, as well as the following products: •Task Management enables users to create and manage processes and task lists. The product provides automatic and recurring taskscheduling, includes configurable workflow and provides a management console for accounting and finance projects. Though mostcommonly used with the financial close, users can create task lists and projects for hundreds of different use cases ranging fromexternal audits to environmental impact surveys. •Journal Entry allows users to manually or automatically generate, review and post manual journal entries. Journals can beautomatically allocated across multiple business units and calculated based on complex, client-defined logic. More importantly, theaddition of validation and approval checkpoints helps ensure the integrity of information passed to other financial applications.Customers can use the Journal Entry product to pass information to hundreds of different ERPs and subsystems in a configurable,easily consumable format. •Variance Analysis provides “always-on” monitoring and automatically identifies anomalous fluctuations in balance sheet and incomestatement account balances. Once an account in flux is identified, users are automatically alerted so they can research anddetermine the source of the fluctuation.10 Intercompany HubIntercompany transactions occur when entities within a corporate parent organization transact with each other. These transactions are someof the most complex and frequent sources of uncertainty for the accounting function. Our Intercompany Hub solution, which was made generallyavailable in November 2015, manages the entire intercompany transaction lifecycle within our platform and we believe it is the only widelyavailable end-to-end intercompany solution. This solution includes the following features: •Intercompany Workflow replaces informal, ad-hoc intercompany requests and approvals with a simple, structured workflow approvalprocess. The application stores permissions by entity and transaction type, ensuring that both the initiator and the approver of theintercompany transaction are authorized to conduct business. •Intercompany Processing records an organization’s intercompany transactions once they reach an appropriate completion level andposts them to the appropriate systems from a single source. The product automatically incorporates local taxes, exchange rates,invoicing requirements, and customer-specific transfer pricing so that the resulting journal entries will net, which reduces thepossibility of intercompany differences and eliminates the need to perform a manual reconciliation. •Netting and Settlement automatically generate a real-time, aggregated settlement matrix, which shows the balance of transactionsacross an entire organization. Users can filter the information by transaction type, currency or business relationship, easing theprocess of netting transactions and helping them make informed, strategic decisions.InsightsOur platform provides us with detailed information about the accounting and finance function for most of our cloud-based customers.Insights, which was made generally available in November 2015, aggregates and analyzes that information and can help clients assessproductivity, risk and timeliness. We also provide a series of key performance indicators and allow clients to compare metrics across their ownoperating entities, set goals and gauge their performance over time. Insights provides benchmarking, scores for a variety of industries, companysizes, and geographies. These benchmarks are drawn from actual client usage of the application, rather than survey data, which provides valuablecontext for users.ServicesCustomer service is essential to our success. We offer the following services for our customers: •Implementation. With a focus on configuration over customization, our implementation approach favors rapid and efficientdeployments led by accounting experts, rather than technical resources. A typical project will focus on mapping our application to acustomer’s current or ideal process, coaching them on best practices, and helping organizations become self-sufficient, instead ofdependent on additional professional services. For clients that elect to work with a business process outsourcer or other company forimplementation services, our implementation team provides ongoing support in order to ensure that the implementation or financetransformation projects are completed successfully. We generally provide this service for a fixed fee. •Support. We provide live customer support 24/7/365 from our offices in Los Angeles, Sydney and London. All customers haveaccess to support resources by phone, email or through our portal, free of charge. •Customer Success. Our customer success managers, many of whom are former users, provide customers with best practices andhelp create a roadmap for expanded usage of our platform. We believe that this service, which is made available to all customers, iscentral to our retention and upsell efforts. •Training. We offer a variety of live and web-based training options, but most customers elect to consume their training through our e-learning environment, BlackLine U. Courses cover platform functionality, as well as the underlying concepts that make reconciliation,the financial close and other accounting and finance activities necessary.Sales and MarketingWe sell our solutions through our direct sales force. Our enterprise field sales team focuses on selling our solutions to large, globalenterprises with annual revenues above $500 million and focuses on maximizing the lifetime value of our customer relationships through retentionand upsell efforts.

We leverage online and offlinemarketing channels on a global basis and organize customer roundtables and user conferences and release white papers, case studies, blogs, anddigital programs and seminars. We have further extended our brand awareness through sponsorships with leading industry organizations such asthe American Institute of Certified Public Accountants, or AICPA, the Institute of Management Accountants, or IMA, the Financial ExecutivesInternational, or FEI, the Institute of Chartered Accountants in England and Wales, or ICAEW, and the Association of Chartered CertifiedAccountants, or ACCA.Technology, Operations and DevelopmentTechnologyOur platform has been designed to deliver a consistent, scalable, high-performing, and secure experience for our customers. Our platform isenabled by rules engines, flexible templates, role-based workflows, and accounting-specific business logic. We deliver our hosted solution on asingle code base and via a multi-tenant architecture with unique database instances for each customer. All SaaS customers run the currentversion of our platform and access it through a web browser. We utilize industry-leading hardware and software components to deliver on thefollowing objectives: •Scalability and Performance. Our platform supports a high, sustained level of client activity and a large, globally distributed clientbase while remaining high-performing and reliable. Our infrastructure incorporates load balancing technology and can scale quickly toabsorb spikes in usage. We also monitor application performance and intervene, as necessary, to prevent degradation. Finally, ourplatform incorporates technologies to manage volume within the solutions. These include a near real-time data warehouse, a high-volume transaction processing engine and a custom-built user interface. •Reliability. During 2017, we had one unscheduled downtime of 1 hour and 41 minutes on April 19, 2017 and 99.98% totalavailability, including scheduled maintenance. Client data is mirrored between primary and alternate data centers, providing effectiveredundancy and disaster recovery. •Flexibility. Our application architecture is modular, which allows us to quickly release new products or expand existing feature-sets by combining and configuring existing components. Our development has always been both rapid and responsive, which allowsus to support a wide array of clients and bring new products to market while maintaining a consistent user interface and single,cohesive code base.SecurityDue to the sensitive nature of the data we store for our clients, we place a heavy emphasis on security. Our infrastructure and softwareproducts are designed to meet and exceed rigorous security standards and to assure customers that we are taking appropriate measure to protecttheir data.We maintain a comprehensive information security management system that extends companywide and integrates into our core technologyand business processes. This system includes deployment of a variety of detective, preventive and deterrent controls that include technical andadministrative safeguards. The controls are regularly tested, both internally and by third-party audits and penetration tests. We are certified forcompliance with the ISO 27001 framework, and we regularly undergo SSAE18, ISAE 3402 and SOC audits. We believe that we are in compliancewith regulatory requirements and that we employ security best practices. A dedicated team of security professionals orchestrate our informationsecurity program. Our information security controls and practices include strong encryption for data at rest and in transit and extensive monitoringwith comprehensive security incident detection and response process.12 OperationsWe host our platform and solutions for our customers in data centers located in North America (Las Vegas, Nevada and Ashburn, Virginia)and Europe (Amsterdam, Netherlands and London, United Kingdom). We contract with SuperNap (Nevada), Equinix (Virginia), Verizon(Netherlands), and VMware (UK) for use of these data center facilities. These facilities provide extensive physical security, including mannedsecurity 365 days a year, 24 hours a day, seven days a week, with video surveillance, redundant power and environmental controls, and technicalcontrols, including biometric access. Network equipment, servers and applications are managed by our employees, and we staff a networkoperations center, or NOC, to monitor performance 365 days a year, 24 hours a day. We regularly conduct risk and security assessments of thesefacilities and review their SSAE18, SOC and/or ISO 27001 attestations and certifications to ensure that our datacenter providers have adequatecontrols to maintain availability and security of our services.DevelopmentOur research and development organization focuses on developing new software solutions and enhancing existing products, conductingsoftware and quality assurance testing and improving our core technology. Our research and development organization is located primarily in ourLos Angeles, California headquarters, where we are committed to recruiting, hiring and retaining top technical talent. We invest substantialresources in research and development to drive core technology innovation and to bring new products to market.Our research and development expenses were $23.9 million, $21.1 million, and $18.2 million for the years ended December 31, 2017, 2016,and 2015, respectively. Our research and development expenses as a percentage of revenues were 13.5%, 17.2%, and 21.8% for the years endedDecember 31, 2017, 2016, and 2015, respectively.CompetitionThe market for accounting and financial software and services is competitive, rapidly evolving and requires deep understanding of theindustry standards, accounting rules and global financial regulations.We compete with vendors of financial automation software such as Trintech, and we also compete with components of Oracle’s Hyperionsoftware.We believe the principal competitive factors in our market include the following: •level of customer satisfaction; •ease of deployment and use of applications; •ability to integrate with multiple legacy enterprise infrastructures and third-party applications; •domain expertise on accounting best practices; •ability to innovate and respond to customer needs rapidly; •capability for configurability, integration and scalability of applications; •cloud-based delivery model; •advanced security and reliability features; •brand recognition and historical operating performance; and •price and total cost of ownership.We believe we are positioned favorably against our competitors based on these factors. However, certain of our competitors may havegreater name recognition, longer operating histories, more established customer and marketing relationships, larger marketing budgets, andsignificantly greater resources.Intellectual Property and Proprietary RightsOur intellectual property and proprietary rights are important to our business. We currently have one pending patent application. We primarilyrely on copyright, trade secret and trademark laws, trade secret protection, and confidentiality or13 license agreements with our employees, customers, partners, and others to protect our intellectual property rights. Though we rely in part uponthese legal and contractual protections, we believe that factors such as the skills and ingenuity of our employees and the functionality andfrequent enhancements to our solutions are larger contributors to our success in the marketplace.Despite our efforts to preserve and protect our intellectual property and proprietary rights, unauthorized third parties may attempt to copy,reverse engineer or otherwise obtain portions of our software. Competitors may attempt to develop similar products that could compete in thesame market as our products. Unauthorized disclosure of our confidential information by our employees or third parties could occur. Laws of otherjurisdictions may not protect our intellectual property and proprietary rights from unauthorized use or disclosure in the same manner as the UnitedStates. The risk of unauthorized use of our proprietary and intellectual property rights may increase as our company continues to expand outsideof the United States.Third-party infringement claims are also possible in our industry, especially as software functionality and features expand, evolve andoverlap with other industry segments.Information about Segment and Geographic RevenueInformation about segment and geographic revenue is set forth in Notes 2 and 16 of the “Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements” under Part II, Item 8 of this Annual Report on Form 10-K.Employees and CultureWe believe our employees and culture are fundamental to our success. Therese Tucker, our founder and Chief Executive Officer, has ledour company since its inception in 2001 and has built and maintained a culture committed to empowering our employees and communities aroundus. Our motto “Think. Create. Serve.” expresses our core values as a company dedicated to innovation and creativity, collaboration and action andservice to each other and our customers.We seek to hire talented employees and are focused on their long-term development and training. We work to foster a collaborative,performance-driven working environment where integrity, open and honest communication and accountability are embraced and cultivated. Bymixing these important features with an element of fun, we seek to maintain a satisfying workplace for our employees. We are proud of ourrecognition as a best place to work in the Los Angeles area in 2013, 2014, 2015, 2016 and 2017.Many of our employees have previously worked for our customers. We believe this uniquely positions us to build compelling and effectiveproducts while also enhancing the user experience for our customers. Our desire to build a platform that creates value for all stakeholders in theaccounting and financial process informs our decisions regarding product design and development.We also believe in making a positive impact on our communities. Each year during our annual Users Conference, we join with ourcustomers to perform a day of community service — in 2016 and 2017, through a joint event with LA Mission, our employees, interested clientsand partners volunteered their time to distribute food to local needy residents. In 2014 and 2015, through joint events with Windy City Habitat forHumanity and Atlanta-based Habitat for Humanity, we helped to rebuild homes in the cities of Chicago and Atlanta.At December 31, 2017, we employed 740 people globally. None of our employees are represented by a labor union or covered by acollective bargaining agreement. We have not experienced any work stoppages, and we consider our relations with our employees to be good.Corporate InformationWe were incorporated in Delaware in May 2001.

You should carefully consider the risks and uncertainties described below,together with all of the other information in this Annual Report on Form 10-K, including “Management’s Discussion and Analysis of FinancialCondition and Results of Operations” and our consolidated financial statements and related notes, before making a decision to invest in ourcommon stock. The risks and uncertainties described below are not the only ones we face. Additional risk and uncertainties not presently knownto us or that we presently deem less significant may also impair our business operations. If any of the events or circumstances described in thefollowing risk factors actually occurs, our business, operating results, financial condition, cash flows, and prospects could be materially andadversely affected. In that event, the market price of our common stock could decline, and you could lose part or all of your investment.Risks Related to Our Business and IndustryIf we are unable to attract new customers and expand sales to existing customers, our business growth could be slower than we expectand our business may be harmed.Our future growth depends in part upon increasing our customer base. Our ability to achieve significant growth in revenues in the future willdepend, in large part, upon the effectiveness of our sales and marketing efforts, both domestically and internationally. We may have difficultyattracting a potential client that has already invested substantial personnel and financial resources to integrate on-premise software into itsbusiness, as such organizations may be reluctant or unwilling to invest in a new product. If we fail to attract new customers or maintain andexpand those customer relationships, our revenues will grow more slowly than expected and our business will be harmed.Our future growth also depends upon our ability to add users and sell additional products to our existing customers. It is important for thefuture growth of our business that our existing customers make additional significant purchases of our products and add additional users to ourplatform. Our business also depends on retaining existing customers. If we do not retain customers, our customers do not purchase additionalproducts or we do not add additional users to our platform, our revenues may grow more slowly than expected, may not grow at all or may decline.Additionally, increasing incremental sales to our current customer base may require additional sales efforts that are targeted at senior15 management. There can be no assurance that our efforts would result in increased sales to existing customers or additional revenues.Our business and growth depend substantially on customers renewing their subscription agreements with us and any decline in ourcustomer renewals could adversely affect our future operating results.Our initial subscription period for the majority of our customers is one to three years. In order for us to continue to increase our revenue, it isimportant that our existing customers renew their subscription agreements when the initial contract term expires. Although our agreementstypically include automatic renewal language, our customers may cancel their agreements at the expiration of the initial term. In addition, ourcustomers may renew for fewer users, renew for shorter contract lengths or renew for fewer products or solutions. Our customers’ renewal ratesmay decline or fluctuate as a result of a variety of factors, including their satisfaction or dissatisfaction with our software or professional services,our pricing or pricing structure, the pricing or capabilities of products or services offered by our competitors, the effects of economic conditions orreductions in our customers’ spending levels. As the markets for our existing solutions mature, or as current and future competitors introduce newproducts or services that compete with ours, we may experience pricing pressure and be unable to renew our agreements with existing customersor attract new customers at prices that are profitable to us. If this were to occur, it is possible that we would have to change our pricing model,offer price incentives or reduce our prices. If our customers do not renew their agreements with us or renew on terms less favorable to us, ourrevenues may decline.We have a history of losses and we may not be able to generate sufficient revenue to achieve or sustain profitability.We have incurred net losses in recent periods, including $38.1 million, $39.2 million, and $24.7 million for the years ended December 31,2017, 2016, and 2015, respectively. We had an accumulated deficit of $125.5 million at December 31, 2017. We may not be able to generatesufficient revenue to achieve and sustain profitability. We also expect our costs to increase in future periods as we continue to expend substantialfinancial and other resources on: •development of our cloud-based platform, including investments in research and development, product innovation to expand thefeatures and functionality of our software solutions and improvements to the scalability and security of our platform; •sales and marketing, including expansion of our direct sales force and our relationships with technology vendors, professionalservices firms, business process outsourcers and resellers; •additional international expansion in an effort to increase our customer base and sales; and •general administration, including legal, accounting and other expenses related to being a public company.These investments may not result in increased revenue or growth of our business or any growth in revenue and may not be sufficient tooffset the expense and may harm our profitability. If we fail to continue to grow our revenue, we may not achieve or sustain profitability.We have experienced rapid growth and organizational change in recent periods and if we fail to manage our growth effectively, we maybe unable to execute our business plan.We increased our number of full-time employees from 183 at December 31, 2013 to 740 at December 31, 2017 as we have experiencedgrowth in number of customers and expanded our operations. Our growth has placed, and may continue to place, a significant strain on ourmanagerial, administrative, operational, financial and other resources. We intend to further expand our headcount and operations both domesticallyand internationally, with no assurance that our business or revenue will continue to grow. Continuing to create a global organization and managinga geographically dispersed workforce will require substantial management effort, the allocation of valuable management resources and significantadditional investment in our infrastructure. We will be required to continually improve our operational, financial and management controls and ourreporting procedures and we may not be able to do so effectively, which could negatively affect our results of operations and overall business. Inaddition, we may be unable to manage our expenses effectively in the future, which may negatively impact our gross margins or operatingexpenses in any particular quarter. Moreover, if we fail to manage our anticipated growth and change in a manner that preserves the key aspectsof our corporate culture, the quality of our software solutions may suffer, which could negatively affect our brand and reputation and harm ourability to retain and attract customers.16 Our quarterly results may fluctuate, and if we fail to meet the expectations of analysts or investors, our stock price and the value of yourinvestment could decline substantially.Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control. If our quarterlyfinancial results fall below the expectations of investors or any securities analysts who may follow our stock, the price of our common stock coulddecline substantially. Some of the important factors that may cause our revenue, operating results and cash flows to fluctuate from quarter toquarter include: •our ability to attract new customers and retain and increase sales to existing customers; •the number of new employees added; •the rate of expansion and productivity of our sales force; •long sales cycles and the timing of large contracts; •changes in our or our competitors’ pricing policies; •the amount and timing of operating costs and capital expenditures related to the operations and expansion of our business; •new products, features or functionalities introduced by us and our competitors; •significant security breaches, technical difficulties or interruptions to our platform; •the timing of customer payments and payment defaults by customers; •general economic conditions that may adversely affect either our customers’ ability or willingness to purchase additional products orservices, delay a prospective customer’s purchasing decision or affect customer retention; •changes in foreign currency exchange rates; •the impact of new accounting pronouncements; •the impact and timing of taxes or changes in tax law; •the timing and the amount of grants or vesting of equity awards to employees; •seasonality of our business; and •changes in customer buying patterns.Many of these factors are outside of our control, and the occurrence of one or more of them might cause our revenue, operating results, andcash flows to vary widely. As such, we believe that quarter-to-quarter comparisons of our revenue, operating results and cash flows may not bemeaningful and should not be relied upon as an indication of future performance.If we are not able to provide successful enhancements, new features or modifications to our software solutions, our business could beadversely affected.If we are unable to provide enhancements and new features for our existing solutions or new solutions that achieve market acceptance orthat keep pace with rapid technological developments, our business could be adversely affected. The success of enhancements, new productsand solutions depends on several factors, including timely completion, introduction and market acceptance. We must continue to meet changingexpectations and requirements of our customers and, because our platform is designed to operate on a variety of systems, we will need tocontinuously modify and enhance our solutions to keep pace with changes in internet-related hardware and other software, communication,browser and database technologies. Our platform is also designed to integrate with existing enterprise resource planning (“ERP”) systems such asNetSuite, Oracle, SAP and Workday, and will require modifications and enhancements as these systems change over time. Any failure of oursolutions to operate effectively with future platforms and technologies could reduce the demand for our solutions or result in customerdissatisfaction. Furthermore, uncertainties about the timing and nature of new solutions or technologies, or modifications to existing solutions ortechnologies, could increase our research and development expenses. If we are not successful in developing modifications and enhancements toour solutions or if we fail to bring them to market in a timely fashion, our solutions may become less marketable, less competitive or obsolete, ourrevenue growth may be significantly impaired and our business could be adversely affected.17 We derive substantially all of our revenues from a limited number of software solutions, and our future growth is dependent on theirsuccess.We currently derive and expect to continue to derive substantially all of our revenues from our Close Process Management solution. Assuch, the continued growth in market demand for this solution is critical to our continued success. We have recently introduced two new softwaresolutions, Intercompany Hub and Smart Close, and one new software product, Insights, but cannot be certain that they will generate significantrevenues. Accordingly, our business and financial results will be substantially dependent on a limited number of solutions.If our relationships with technology vendors and business process outsourcers are not successful, our business and growth will beharmed.We depend on, and anticipate that we will continue to depend on, various strategic relationships in order to sustain and grow our business.We have established strong relationships with technology vendors such as SAP and NetSuite to market our solutions to users of their ERPsolutions, and professional services firms such as Deloitte, Ernst & Young, and KPMG, and business process outsourcers such as Cognizant,Genpact and IBM to supplement delivery and implementation of our applications. We believe these relationships enable us to effectively marketour solutions by offering a complementary suite of services. In particular, we have a strategic relationship with SAP to market our solution to usersof SAP’s ERP solutions. Our solution is an SAP-endorsed business solution that integrates with SAP’s ERP solutions. Under our agreement withSAP, which we entered into in 2013, we pay SAP a fee based on a percentage of revenues from our new customers that use an SAP ERPsystem. We continue to pay SAP a fee for these customers over the term of their subscription agreements. Revenues from our customers thatuse an SAP ERP solution accounted for $33.3 million, or 19%, of our total revenues, $20.7 million, or 17%, of our total revenues, and $9.4 million,or 11%, of our total revenues for the years ended December 31, 2017, 2016, and 2015, respectively. If we are unsuccessful in maintaining ourrelationship with SAP, or if we are unsuccessful in supporting or expanding our relationships with other companies, our business would beadversely affected.Identifying, negotiating and documenting relationships with other companies require significant time and resources. Our agreements withtechnology vendors are typically limited in duration, non-exclusive, cancellable upon notice and do not prohibit the counterparties from working withour competitors or from offering competing services. For example, our agreement with SAP can be terminated by either party upon six months’notice and there is no assurance that our relationship with SAP will continue. If we are no longer an SAP-endorsed business solution, our businesscould be adversely affected. Our competitors may be effective in providing incentives to third parties to favor their products or services or toprevent or reduce subscriptions to our platform. If we are unsuccessful in establishing or maintaining our relationships, our ability to compete in themarketplace or to grow our revenue could be impaired and our operating results would suffer. Even if we are successful, we cannot assure you thatthese relationships will result in improved operating results.If our security controls are breached or unauthorized, or inadvertent access to customer, employee or other confidential data isotherwise obtained, our software solutions may be perceived as insecure, we may lose existing customers or fail to attract newcustomers, our business may be harmed and we may incur significant liabilities.Use of our platform involves the storage, transmission and processing of our customers’ proprietary data, including highly confidentialfinancial information regarding their business and personal or identifying information regarding their customers or employees. Our platform is at riskfor breaches as a result of third-party action, employee, vendor or contractor error, malfeasance or other factors. If any unauthorized or inadvertentaccess to or a security breach of our platform occurs, or is believed to occur, such an event could result in the loss of data, loss of business,severe reputational damage adversely affecting customer or investor confidence, regulatory investigations and orders, litigation, indemnityobligations, damages for contract breach or penalties for violation of applicable laws or regulations. We may also suffer breaches of our internalsystems. Security breaches of our platform or our internal systems could also result in significant costs for remediation that may include liabilityfor stolen assets or information and repair of system damage that may have been caused, incentives offered to customers or other businesspartners in an effort to maintain business relationships after a breach, and other liabilities.Additionally, many jurisdictions have enacted laws requiring companies to notify individuals of data security breaches involving certaintypes of personal data. These mandatory disclosures regarding a security breach could result in negative publicity to us, which may cause ourcustomers to lose confidence in the effectiveness of our data security measures which could impact our operating results.18 We incur significant expenses to prevent security breaches, including deploying additional personnel and protection technologies, trainingemployees, and engaging third-party experts and contractors. If a high profile security breach occurs with respect to another Software as a Service(“SaaS”) provider, our clients and potential clients may lose trust in the security of our platform or in the SaaS business model generally, whichcould adversely impact our ability to retain existing clients or attract new ones. Even in the absence of any security breach, customer concernsabout security, privacy, or data protection may deter them from using our platform for activities that involve personal or other sensitive information.Our errors and omissions insurance policies covering certain security and privacy damages and claim expenses may not be sufficient tocompensate for all potential liability. Although we maintain cyber liability insurance, we cannot be certain that our coverage will be adequate forliabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all.Because the techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not identified untilthey are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. We mayalso experience security breaches that may remain undetected for an extended period. From time to time, we experience cyber security eventsincluding directed “phishing” attacks against our employees, web attacks and other information technology incidents that are typical for a SaaScompany of our size. These threats continue to evolve and are difficult to predict due to advances in computer capabilities, new discoveries in thefield of cryptography and new and sophisticated methods used by criminals including phishing, social engineering or other illicit acts. There can beno assurances that our defensive measures will prevent cyber-attacks and any incidents could damage our brand and reputation and negativelyimpact our business.Because data security is a critical competitive factor in our industry, we make numerous statements in our privacy policy and customeragreements, through our certifications to privacy standards and in our marketing materials, providing assurances about the security of our platformincluding detailed descriptions of security measures we employ. Should any of these statements be untrue or become untrue, even throughcircumstances beyond our reasonable control, we may face claims of misrepresentation or deceptiveness by the U.S. Federal Trade Commission,state and foreign regulators and private litigants. Our errors and omissions insurance coverage covering security and privacy damages and claimexpenses may not be sufficient to compensate for all liabilities.Interruptions or performance problems associated with our software solutions, platform and technology may adversely affect ourbusiness and operating results.Our continued growth depends in part on the ability of our existing and potential customers to access our platform at any time. Our platformis proprietary, and we rely on the expertise of members of our engineering, operations and software development teams for its continuedperformance. We have experienced, and may in the future experience, disruptions, outages and other performance problems due to a variety offactors, including infrastructure changes, introductions of new functionality, human or software errors, capacity constraints due to an overwhelmingnumber of users accessing our platform simultaneously, denial of service attacks or other security related incidents. In some instances, we maynot be able to identify the cause or causes of these performance problems within an acceptable period of time. Because of the seasonal nature offinancial close activities, increasing complexity of our platform and expanding user population, it may become difficult to accurately predict andtimely address performance and capacity needs during peak load times. If our platform is unavailable or if our users are unable to access it withina reasonable amount of time or at all, our business would be harmed. In addition, our infrastructure does not currently include the real-timemirroring of data. Therefore, in the event of any of the factors described above, or other failures of our infrastructure, customer data may bepermanently lost. Our customer agreements typically include performance guarantees and service level standards that obligate us to providecredits in the event of a significant disruption in our platform. To the extent that we do not effectively address capacity constraints, upgrade oursystems and continually develop our technology and network architecture to accommodate actual and anticipated changes in technology, ourbusiness and operating results may be adversely affected.If our software contains serious errors or defects, we may lose revenue and market acceptance and may incur costs to defend or settleproduct liability claims.Complex software such as ours often contains errors or defects, particularly when first introduced or when new versions or enhancementsare released. Despite internal and third-party testing and testing by our customers, our current and future software may contain serious defects,which could result in lost revenue or a delay in market acceptance.Since our customers use our platform for critical business functions such as assisting in the financial close or account reconciliationprocess, errors, defects or other performance problems could result in damage to our customers.19 They could seek significant compensation from us for the losses they suffer. Although our customer agreements typically contain provisionsdesigned to limit our exposure to product liability claims, existing or future laws or unfavorable judicial decisions could negate these limitations.Even if not successful, a product liability claim brought against us would likely be time-consuming and costly and could seriously damage ourreputation in the marketplace, making it harder for us to sell our products.We depend on our executive officers and other key employees and the loss of one or more of these employees or an inability to attractand retain highly-skilled employees could adversely affect our business.Our success depends largely upon the continued services of our executive officers and other key employees. We rely on our leadershipteam in the areas of research and development, operations, security, marketing, sales and general and administrative functions. In particular, ourfounder and Chief Executive Officer provides our strategic direction and has built and maintained what we believe is an attractive workplaceculture. Any failure to preserve our culture could negatively affect our ability to recruit and retain personnel. From time to time, there may bechanges in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. Key membersof our current management and finance teams have only been working together for a relatively short period of time. If we are not successful inintegrating these key employees into our organization, such failure could disrupt our business operations. We do not have employment agreementswith our executive officers or other key personnel that require them to continue to work for us for any specified period and, therefore, they couldterminate their employment with us at any time. The loss of one or more of our executive officers or key employees, especially our founder andChief Executive Officer, could have an adverse effect on our business.In addition, to execute our growth plan, we must attract and retain highly-qualified personnel. Competition for personnel is intense, especiallyfor engineers experienced in designing and developing software applications and experienced sales professionals. We have, from time to timeexperienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of thecompanies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or othercompanies, their former employers may attempt to assert that these employees or we have breached their legal obligations, resulting in a diversionof our time and resources. Likewise, if competitors hire our employees, we may divert time and resources to deterring any breach by our formeremployees or their new employers of their legal obligations. Given the competitive nature of our industry, we have both received and asserted suchclaims in the past. In addition, job candidates and existing employees often consider the value of the equity awards they receive in connectionwith their employment. If the perceived value of our equity awards declines, it may adversely affect our ability to recruit and retain highly-skilledemployees. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects couldbe adversely affected.If our industry does not continue to develop as we anticipate or if potential customers do not continue to adopt our platform, our saleswould not grow as quickly as expected, or at all, and our business and operating results and financial condition would be adverselyaffected.We operate in a rapidly evolving industry focused on modernizing financial and accounting operations. Our solutions are relatively new andhave been developed to respond to an increasingly global and complex business environment with more rigorous regulatory standards. Iforganizations do not increasingly allocate their budgets to financial automation software as we expect or if we do not succeed in convincingpotential customers that our platform should be an integral part of their overall approach to their accounting processes, our sales may not grow asquickly as anticipated, or at all. Our business is substantially dependent on enterprises recognizing that accounting errors and inefficiencies arepervasive and are not effectively addressed by legacy solutions. Future deterioration in general economic conditions may also cause ourcustomers to cut their overall information technology spending, and such cuts may disproportionately affect software solutions like ours to theextent customers view our solutions as discretionary. If our revenue does not increase for any of these reasons, or any other reason, ourbusiness, financial condition and operating results may be materially adversely affected.The market in which we participate is intensely competitive, and if we do not compete effectively, our operating results could be harmed.The market for accounting and financial software and services is highly competitive and rapidly evolving. Our competitors vary in size andin the breadth and scope of the products and services they offer. We often compete with other vendors of financial automation software such asTrintech. We also compete with large, well-established, enterprise application software vendors, such as Oracle, whose Hyperion softwarecontains components that compete with our platform. In the future, a competitor offering ERP software could include a free service similar to oursas part of its standard20 offerings or may offer a free standalone version of a service similar to ours. Further, other established software vendors not currently focused onaccounting and finance software and services may expand their services to compete with us.Our competitors may have greater name recognition, longer operating histories, more established customer and marketing relationships,larger marketing budgets and significantly greater resources than we do. They may be able to respond more quickly and effectively than we can tonew or changing opportunities, technologies, standards, or customer requirements. In addition, some of our competitors have partnered with, orhave acquired, and may in the future partner with or acquire, other competitors to offer services, leveraging their collective competitive positions,which makes, or would make, it more difficult to compete with them.With the introduction of new technologies, the evolution of our platform and new market entrants, we expect competition to intensify in thefuture. Increased competition generally could result in reduced sales, reduced margins, losses or the failure of our platform to achieve or maintainmore widespread market acceptance, any of which could harm our business.Our financial results may fluctuate due to our long and increasingly variable sales cycle.Our sales cycle generally varies in duration between four to nine months and, in some cases, even longer depending on the size of thepotential customer, the size of the potential contract and the type of solution or product being purchased. The sales cycle for our global enterprisecustomers is generally longer than that of our mid-market customers. In addition, the length of the sales cycle tends to increase for largercontracts and for more complex, strategic products like Intercompany Hub. As we continue to focus on increasing our average contract size andselling more strategic products, we expect our sales cycle to lengthen and become less predictable. This could cause variability in our operatingresults for any particular period.A number of other factors that may influence the length and variability of our sales cycle include: •the need to educate potential customers about the uses and benefits of our software solutions; •the need to educate potential customers on the differences between traditional, on-premise software and SaaS solutions; •the relatively long duration of the commitment customers make in their agreements with us; •the discretionary nature and timing of potential customers’ purchasing and budget cycles and decisions; •the competitive nature of potential customers’ evaluation and purchasing processes; •announcements or planned introductions of new products by us or our competitors; and •lengthy purchasing approval processes of potential customers.We may incur higher costs and longer sales cycles as a result of large enterprises representing an increased portion of our revenue. In thismarket, the decision to subscribe to our solutions may require the approval of more technical and information security personnel and managementlevels within a potential customer’s organization, and if so, these types of sales require us to invest more time educating these potentialcustomers. In addition, larger organizations may demand more features and integration services and have increased purchasing power andleverage in negotiating contractual arrangements with us, which may contain restrictive terms favorable to the larger organization. As a result ofthese factors, these sales opportunities may require us to devote greater research and development, sales, product support and professionalservices resources to individual customers, resulting in increased costs and reduced profitability, and would likely lengthen our typical sales cycle,which could strain our resources.21 In addition, more sales are closed in the last month of a quarter than other times. If we are unable to close sufficient transactions in a particularperiod, or if a significant amount of transactions are delayed until a subsequent period, our operating results for that period, and for any futureperiods in which revenue from such transaction would otherwise have been recognized, may be adversely affected.Failure to effectively organize or expand our sales capabilities could harm our ability to increase our customer base.Increasing our customer base and sales will depend, to a significant extent, on our ability to effectively organize and expand our sales andmarketing operations and activities. From January 1, 2014 to December 31, 2017, our sales and marketing teams increased from 68 to 372employees. As we’ve grown and scaled our operations, we have aligned our sales team to help streamline the customer experience. We rely onour direct sales force to obtain new customers and on our enterprise field sales team and account management team to maximize the lifetimevalue of our customer relationships through retention and upsell efforts. Our success will depend, in part, on our ability to support new andexisting customer growth and maintain customer satisfaction. If we cannot provide the tools and training to our teams to efficiently do their jobsand satisfy customer demands, we may not be able to achieve anticipated revenue growth as quickly as expected.In addition, we plan to continue to expand our direct sales force both domestically and internationally. We believe that there is significantcompetition for experienced sales professionals with the sales skills and technical knowledge that we require. Our ability to achieve significantrevenue growth in the future will depend, in part, on our success in recruiting, training, and retaining a sufficient number of experienced salesprofessionals. New hires require significant training and time before they achieve full productivity, particularly in new sales segments andterritories. Our recent hires and planned hires may not become as productive as quickly as we expect, and we may be unable to hire or retainsufficient numbers of qualified individuals in the future in the markets where we do business. Our business will be harmed if our sales expansionefforts do not generate a significant increase in revenue.We recognize subscription revenue over the term of our customer contracts and, consequently, downturns or upturns in new sales maynot be immediately reflected in our operating results and may be difficult to discern.We recognize subscription revenue from our platform ratably over the terms of our customers’ agreements, most of which have one-yearterms but an increasing number of which have up to three-year terms. As a result, most of the revenue we report in each quarter is derived fromthe recognition of deferred revenue relating to subscriptions entered into during previous quarters. Consequently, a decline in new or renewedsubscriptions in any single quarter may have a small impact on our revenue results for that quarter. However, such a decline will negatively affectour revenue in future quarters. Accordingly, the effect of significant downturns in sales and market acceptance of our platform, and potentialchanges in our pricing policies or rate of expansion or retention, may not be fully reflected in our results of operations until future periods. We mayalso be unable to reduce our cost structure in line with a significant deterioration in sales. In addition, a significant majority of our costs areexpensed as incurred, while revenue is recognized over the life of the agreement with our customer. As a result, increased growth in the number ofour customers could continue to result in our recognition of more costs than revenue in the earlier periods of the terms of our agreements. Oursubscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from newcustomers must be recognized over the applicable subscription term.We previously identified material weaknesses in our internal control over financial reporting. Although we believe these materialweaknesses have since been remediated, we may identify material weaknesses in the future or otherwise fail to maintain an effectivesystem of internal control over financial reporting in the future and may not be able to accurately or timely report our financial conditionor results of operations, which may adversely affect investor confidence in us and the price of our common stock.As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in suchinternal controls. Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), requires that we evaluate and determine theeffectiveness of our internal control over financial reporting and, beginning with this Annual Report on Form 10-K for the year ended December 31,2017, provide a management report on internal control over financial reporting. During 2015, we identified material weaknesses in our internalcontrol over financial reporting. Although we remediated these material weaknesses as of December 31, 2016, we cannot assure you thatadditional material weaknesses in our internal control over financial reporting will not be identified in the future.22 The process of designing and implementing internal control over financial reporting required to comply with Section 404 of the Sarbanes-Oxley Act has been and will continue to be time consuming, costly and complicated. If, during the evaluation and testing process, we identify oneor more material weaknesses in our internal control over financial reporting, our management will be unable to assert that our internal control overfinancial reporting is effective. Even if our management concludes that our internal control over financial reporting is effective, our independentregistered public accounting firm may conclude that there are material weaknesses with respect to our internal controls or the level at which ourinternal controls are documented, designed, implemented, or reviewed. If we are unable to assert that our internal control over financial reporting iseffective, or when required in the future, if our independent registered public accounting firm is unable to express an opinion as to the effectivenessof our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the marketprice of our common stock could be adversely affected, and we could become subject to stockholder lawsuits, litigation or investigations by thestock exchange on which our securities are listed, the SEC, or other regulatory authorities, which could require additional financial andmanagement resources, and cause investor perceptions to be adversely affected and potentially resulting in restatement of our financialstatements for prior periods and a decline in the market price of our stock.We rely on a limited number of data centers to deliver our cloud-based software solutions and any disruption of service at these centerscould harm our business.We manage our software solutions and serve most of our customers using a cloud-based infrastructure that is operated by a limited numberof third-party data center facilities in North America and Europe. We do not control the operation of these facilities. Any changes in third-partyservice levels at our data centers or any disruptions or delays from errors, defects, hacking incidents, security breaches, computer viruses, badacts or performance problems could harm our reputation, damage our customers’ businesses, and adversely affect our business and operatingresults. Our data centers are also vulnerable to damage or interruption from earthquakes, hurricanes, floods, fires, war, terrorist attacks, powerlosses, hardware failures, systems failures, telecommunications failures and similar events. If our data centers were compromised or unavailableor our users were unable to access our solutions for any reason, our business and operations would be materially and adversely affected.Our customers have experienced minor disruptions and outages in accessing our solutions in the past, and may in the future experience,disruptions, outages and other performance problems. Although we expend considerable effort to ensure that our platform performance is capableof handling existing and increased traffic levels, the ability of our cloud-based solutions to effectively manage any increased capacity requirementsdepends on our third-party providers. Our third-party data center providers may not be able to meet such performance requirements, especially tocover peak levels or spikes in traffic, and as a result, our customers may experience delays in accessing our solutions or encounter slowerperformance in our solutions, which could significantly harm the operations of these facilities. Interruptions in our services might reduce ourrevenue, cause us to issue credits to customers, subject us to potential liability, and cause customers to terminate their subscriptions or harm ourrenewal rates.If we do not accurately predict our infrastructure capacity requirements, our customers could experience service shortfalls. The provisioningof additional cloud hosting capacity and data center infrastructure requires lead time. As we continue to add data centers, restructure our datamanagement plans, and increase capacity in existing and future data centers, we have and expect to in the future move or transfer our data andour customers’ data. Despite precautions taken during such processes and procedures, any unsuccessful data transfers may impair the delivery ofour service, and we may experience costs or downtime in connection with the transfer of data to other facilities which may lead to, among otherthings, customer dissatisfaction and non-renewals. The owners of our data center facilities have no obligation to renew their agreements with us oncommercially reasonable terms, or at all. If we are unable to renew these agreements on commercially reasonable terms, we may be required totransfer to new data center facilities, and we may incur significant costs and possible service interruption in connection with doing so.If we are unable to develop and maintain successful relationships with resellers, our business, operating results and financial conditioncould be adversely affected.We believe that continued growth in our business is dependent upon identifying, developing, and maintaining strategic relationships withcompanies that resell our solutions. We plan to expand our small but growing network of resellers and to add new resellers, in particular to helpgrow our mid-market business globally. Our agreements with our existing resellers are non-exclusive, meaning resellers may offer customers theproducts of several different companies, including products that compete with ours. They may also cease marketing our solutions with limited orno notice and with little or no penalty. We expect that any additional resellers we identify and develop will be similarly non-exclusive and not boundby any requirement to continue to market our solutions. If we fail to identify additional resellers, in a timely and23 cost-effective manner, or at all, or are unable to assist our current and future resellers in independently selling our solutions, our business, resultsof operations, and financial condition could be adversely affected. If resellers do not effectively market and sell our solutions, or fail to meet theneeds of our customers, our reputation and ability to grow our business may also be adversely affected.If we are not able to maintain and enhance our brand, our business, operating results and financial condition may be adversely affected.We believe that maintaining and enhancing our reputation for accounting and finance software is critical to our relationships with ourexisting customers and to our ability to attract new customers. The successful promotion of our brand attributes will depend on a number offactors, including our marketing efforts, our ability to continue to develop high-quality software, and our ability to successfully differentiate ourplatform from competitive products and services. Our brand promotion activities may not ultimately be successful or yield increased revenue. Inaddition, independent industry analysts provide reviews of our platform, as well as products and services offered by our competitors, andperception of our platform in the marketplace may be significantly influenced by these reviews. If these reviews are negative, or less positive ascompared to those of our competitors’ products and services, our brand may be adversely affected.The promotion of our brand requires us to make substantial expenditures, and we anticipate that the expenditures will increase as ourmarket becomes more competitive, as we expand into new markets and as more sales are generated. To the extent that these activities yieldincreased revenue, this revenue may not offset the increased expenses we incur. If we do not successfully maintain and enhance our brand, ourbusiness may not grow, we may have reduced pricing power relative to competitors, and we could lose customers or fail to attract potentialcustomers, all of which would adversely affect our business, results of operations and financial condition.Our long-term success depends, in part, on our ability to expand the sales of our solutions to customers located outside of the UnitedStates, and thus our business is susceptible to risks associated with international sales and operations.We currently maintain offices and/or have sales personnel in Australia, Canada, France, Germany, Malaysia, Netherlands, Poland,Singapore, South Africa, and the United Kingdom, and we intend to build out our international operations. As part of our ongoing internationalexpansion strategy, in August 2016, we acquired Runbook, a Netherlands-based provider of financial close automation software solutions to SAPcustomers. We derived approximately 20%,16%, and 14% of our revenues from sales outside the United States for the years ended December 31,2017, 2016, and 2015, respectively. Any international expansion efforts that we may undertake, including our Runbook Acquisition, may not besuccessful. In addition, conducting international operations in new markets subjects us to new risks that we have not generally faced in the UnitedStates. These risks include: •localization of our solutions, including translation into foreign languages and adaptation for local practices and regulatoryrequirements; •lack of familiarity and burdens of complying with foreign laws, legal standards, regulatory requirements, tariffs and other barriers; •unexpected changes in regulatory requirements, taxes, trade laws, tariffs, export quotas, custom duties or other trade restrictions; •differing technology standards; •longer accounts receivable payment cycles and difficulties in collecting accounts receivable; •difficulties in managing and staffing international operations and differing employer/employee relationships; •fluctuations in exchange rates that may increase the volatility of our foreign-based revenue; •potentially adverse tax consequences, including the complexities of foreign value-added tax (or other tax) systems and restrictions onthe repatriation of earnings; •uncertain political and economic climates, including the significant volatility in the global financial markets; and •reduced or varied protection for intellectual property rights in some countries.24 These factors may cause our international costs of doing business to exceed our comparable domestic costs. Operating in internationalmarkets also requires significant management attention and financial resources. Any negative impact from our international business efforts couldnegatively impact our business, results of operations and financial condition as a whole.We may be unable to integrate acquired businesses and technologies successfully or achieve the expected benefits of such transactions.We regularly evaluate and consider potential strategic transactions, including acquisitions of, or investments in, businesses, technologies,services, products, and other assets. For example, in 2016, we completed the Runbook Acquisition. We also may enter into relationships withother businesses to expand our products and services, which could involve preferred or exclusive licenses, additional channels of distributions ordiscount pricing.Any future acquisition, investment or business relationship may result in unforeseen operating difficulties and expenditures. In particular, wemay encounter difficulties assimilating or integrating the businesses, technologies, products, personnel or operations of the acquired companies,particularly if the key personnel of the acquired company choose not to work for us, their software is not easily adapted to work with our platform,or we have difficulty retaining the customers of any acquired business due to changes in ownership, management or otherwise. In addition,Runbook offers an on-premise solution to its customers. If we are unable to migrate those customers to our cloud solution or if we are unable tointegrate Runbook’s on-premise software with our platform, our business may be adversely affected. Acquisitions may also disrupt our business,divert our resources, and require significant management attention that would otherwise be available for development of our existing business.Moreover, the anticipated benefits of any acquisition, investment, or business relationship may not be realized or we may be exposed to unknownrisks or liabilities.Negotiating these transactions can be time-consuming, difficult, and expensive, and our ability to complete these transactions may often besubject to approvals that are beyond our control. Consequently, these transactions, even if announced, may not be completed. For one or more ofthose transactions, we may: •issue additional equity securities that would dilute our existing stockholders; •use cash that we may need in the future to operate our business; •incur large charges or substantial liabilities; •incur debt on terms unfavorable to us or that we are unable to repay; •encounter difficulties retaining key employees of the acquired company or integrating diverse software codes or business cultures;and •become subject to adverse tax consequences, substantial depreciation, and amortization, or deferred compensation charges.We use third-party contractors outside of the United States to supplement our research and development capabilities, which may exposeus to risks, including risks inherent in foreign operations.We use third-party contractors outside of the United States to supplement our research and development capabilities. We currently usethird-party contractors located in Romania and China. Managing operations that are remote from our U.S. headquarters is difficult and we may notbe able to manage these third-party contractors successfully. If we fail to maintain productive relationships with these contractors generally, wemay be required to develop our solutions in a less efficient and cost-effective manner and our product release schedules may be delayed while wehire software developers or find alternative contract development resources. Additionally, while we take precautions to ensure that softwarecomponents developed by our third-party contractors are reviewed and that our source code is protected, misconduct by our third-party contractorscould result in infringement or misappropriation of our intellectual property. Furthermore, any acts of espionage, malware attacks, theft ofconfidential information or other malicious cyber incidents attributed to our third-party contractors may compromise our system infrastructure,expose us to litigation and lead to reputational harm that could result in a material adverse effect on our financial condition and operating results.25 Any failure to protect our intellectual property rights could impair our ability to protect our proprietary technology and our brand.Our success and ability to compete depend, in part, upon our intellectual property. We currently have one patent application, which may notresult in an issued patent. We primarily rely on copyright, trade secret and trademark laws, trade secret protection, and confidentiality or licenseagreements with our employees, customers, partners and others to protect our intellectual property rights. However, the steps we take to protectour intellectual property rights may be inadequate.In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Inthe past, we have utilized demand letters as a means to assert and resolve claims regarding potential misuse of our proprietary or trade secretinformation. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming, and distracting tomanagement, and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectualproperty rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual propertyrights. Our failure to secure, protect and enforce our intellectual property rights could adversely affect our brand and adversely impact ourbusiness.Lawsuits or other claims by third parties for alleged infringement of their proprietary rights could cause us to incur significant expensesor liabilities.There is considerable patent and other intellectual property development activity in our industry. Our future success depends, in part, on notinfringing upon the intellectual property rights of others. From time to time, our competitors or other third parties may claim that our solutions andunderlying technology infringe or violate their intellectual property rights, and we may be found to be infringing upon such rights. We may beunaware of the intellectual property rights of others that may cover some or all of our technology. Any claims or litigation could cause us to incursignificant expenses and, if successfully asserted against us, could require that we pay substantial damages or ongoing royalty payments, preventus from offering our solutions or require that we comply with other unfavorable terms. We may also be obligated to indemnify our customers orother companies in connection with any such litigation and to obtain licenses, modify our solutions, or refund subscription fees, which could furtherexhaust our resources. In addition, we may incur substantial costs to resolve claims or litigation, whether or not successfully asserted against us,which could include payment of significant settlement, royalty or license fees, modification of our solutions, or refunds to customers ofsubscription fees. Even if we were to prevail in the event of claims or litigation against us, any claim or litigation regarding our intellectual propertycould be costly and time-consuming and divert the attention of our management and other employees from our business operations. Such disputescould also disrupt our solutions, adversely impacting our customer satisfaction and ability to attract customers.We use open source software in our products, which could subject us to litigation or other actions.We use open source software in our products and may use more open source software in the future. From time to time, there have beenclaims challenging the use of open source software against companies that incorporate open source software into their products. As a result, wecould be subject to suits by parties claiming misuse of, or a right to compensation for, what we believe to be open source software. Litigation couldbe costly for us to defend, have a negative effect on our operating results and financial condition or require us to devote additional research anddevelopment resources to change our products. In addition, if we were to combine our proprietary software products with open source software in acertain manner, we could, under certain of the open source licenses, be required to release the source code of our proprietary software products. Ifwe inappropriately use open source software, we may be required to re-engineer our products, discontinue the sale of our products or take otherremedial actions.Privacy and data security concerns, and data collection and transfer restrictions and related domestic or foreign regulations may limitthe use and adoption of our solutions and adversely affect our business.Personal privacy, information security, and data protection are significant issues in the United States, Europe and many other jurisdictionswhere we offer our platform. The regulatory framework governing the collection, processing, storage and use of business information, particularlyinformation that affects financial statements, and personal data, is rapidly evolving and any failure or perceived failure to comply with applicableprivacy, security, or data protection laws or regulations may adversely affect our business.The U.S. federal and various state and foreign governments have adopted or proposed requirements regarding the collection, distribution,use, security and storage of personally identifiable information and other data relating to individuals, and federal and state consumer protectionlaws are being applied to enforce regulations related to the online26 collection, use and dissemination of data. Some of these requirements include obligations on companies to notify individuals of security breachesinvolving particular personal information, which could result from breaches experienced by us or by organizations with which we have formedstrategic relationships. Even though we may have contractual protections with such organizations, notifications related to a security breach couldimpact our reputation, harm customer confidence, hurt our expansion into new markets or cause us to lose existing customers.Further, many foreign countries and governmental bodies, including the European Union (the “EU”), where we conduct business and haveoffices, have laws and regulations concerning the collection and use of personal data obtained from their residents or by businesses operatingwithin their jurisdiction. These laws and regulations often are more restrictive than those in the United States. Laws and regulations in thesejurisdictions apply broadly to the collection, use, storage, disclosure and security of data that identifies or may be used to identify or locate anindividual, such as names, email addresses and, in some jurisdictions, Internet Protocol, or IP, addresses. With regard to data transfers ofpersonal data from our European employees and customers to the United States, we historically relied on the U.S. Department of Commerce’sSafe Harbor Privacy Principles and compliance with the U.S.-EU and U.S.-Swiss Safe Harbor Frameworks as agreed to and set forth by the U.S.Department of Commerce, and the European Union and Switzerland, which established means for legitimizing the transfer of personal data bycompanies doing business in Europe from the EU to the United States. As a result of the October 6, 2015 European Court of Justice opinion inCase C-362/14 (Schrems v. Data Protection Commissioner) (the “ECJ Ruling”), the U.S.-EU Safe Harbor Framework was deemed an invalidmethod of compliance with EU restrictions on data transfers. We have taken certain measures to legitimize our transfers of personal data, bothinternally and on behalf of our customers, from the EU to the United States in the wake of the ECJ Ruling. Additionally, EU and U.S. politicalauthorities adopted the U.S. EU Privacy Shield on July 12, 2016, which may provide a new mechanism for companies to transfer EU personal datato the United States. While we now have Privacy Shield certification in place that we believe allow for the lawful transfer of personal data from theEU to the United States, it is possible that these mechanisms may be challenged or evolve to include new legal requirements that could have animpact on data transfers. It is unclear at this time whether the U.S. EU Privacy Shield will serve as an appropriate means for us to transfer EUpersonal data from the EU to the United States. Our means for transferring personal data from the EU may not be adopted by all of our customersand may be subject to legal challenge by data protection authorities, and we may experience reluctance or refusal by European customers to useour solutions due to potential risk exposure as a result of the ECJ Ruling. We and our customers face a risk of enforcement actions taken by EUdata protection authorities regarding data transfers from the EU to the United States.We also expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection andinformation security in the United States, the EU, and other jurisdictions. For example, the European Commission recently adopted a General DataProtection Regulation (the “GDPR”), effective on May 25, 2018, that will supersede current EU data protection legislation, the GDPR becamedirectly applicable to EU member states, imposed more stringent EU data protection requirements for processors and controllers of personal data,and for companies established in the EU and those outside the EU if they collect and use personal data of EU subjects, and provides for greaterpenalties for noncompliance. As the GDPR is a regulation rather than a directive, it applies throughout all EU member states, but permits memberstates to enact supplemental requirements if they so choose. Noncompliance with the GDPR can trigger fines up to €20 million or 4% of globalannual revenues, whichever is higher. We cannot yet determine the impact such future laws, regulations and standards may have on our business.Such laws and regulations are often subject to differing interpretations and may be inconsistent among jurisdictions. These and other requirementscould reduce demand for our service, increase our costs, impair our ability to grow our business, or restrict our ability to store and process data or,in some cases, impact our ability to offer our service in some locations and may subject us to liability. Further, in view of new or modified federal,state or foreign laws and regulations, industry standards, contractual obligations and other legal obligations, or any changes in their interpretation,we may find it necessary or desirable to fundamentally change our business activities and practices or to expend significant resources to modifyour software or platform and otherwise adapt to these changes. We may be unable to make such changes and modifications in a commerciallyreasonable manner or at all, and our ability to develop new products and features could be limited.Further, following a referendum in June 2016 in which voters in the United Kingdom approved an exit from the EU, the United Kingdomgovernment initiated a process to leave the EU in March 2017 and began negotiations to leave the EU in June 2017 (often referred to as “Brexit”),which is expected to be completed within the next two years. The Brexit has created uncertainty with regard to the regulation of data protection inthe United Kingdom. In particular, it is unclear whether the United Kingdom will enact data protection laws or regulations designed to be consistentwith the pending EU GDPR and how data transfers to and from the United Kingdom will be regulated. In the immediate term, the United Kingdomwill remain bound by the EU GDPR following its exit from the EU since the U.K. government has announced its intention to enact a ‘Great RepealBill’ which enshrines all EU law into domestic U.K. legislation. While the U.K. Information Commissioner’s Office has announced that there are noplans to dilute U.K. data protection laws, it is less27 certain how data protection laws or regulations will develop in the medium to longer term, and how data transfers to and from the U.K. will beregulated.Our customers also expect that we comply with regulatory standards that may place additional burdens on us. Our customers expect us tomeet voluntary certifications or adhere to standards established by third parties, such as the SSAE 18, SOC1 and SOC2 audit processes, andmay demand that they be provided a report from our auditors that we are in compliance. If we are unable to maintain these certifications or meetthese standards, it could adversely affect our customers’ demand for our service and could harm our business.The costs of compliance with and other burdens imposed by laws, regulations and standards may limit the use and adoption of our serviceand reduce overall demand for it, or lead to significant fines, penalties or liabilities for any noncompliance. Privacy, information security, and dataprotection concerns, whether valid or not valid, may inhibit market adoption of our platform, particularly in certain industries and foreign countries.We depend and rely upon SaaS applications from third parties to operate our business and interruptions or performance problems withthese technologies may adversely affect our business and operating results.We rely heavily on SaaS applications from third parties in order to operate critical functions of our business, including billing and ordermanagement, enterprise resource planning, and financial accounting services. If these services become unavailable due to extended outages,interruptions, or because they are no longer available on commercially reasonable terms, our expenses could increase, our ability to managefinances could be interrupted and our processes for managing sales of our solutions and supporting our customers could be impaired untilequivalent services, if available, are identified, obtained, and implemented, all of which could adversely affect our business.We rely on third-party computer hardware and software that may be difficult to replace or which could cause errors or failures of oursoftware solutions.We rely on computer hardware purchased or leased and software licensed from third parties in order to deliver our software solutions. Thishardware and software may not continue to be available on commercially reasonable terms, if at all. Any loss of the right to use any of thishardware or software could result in delaying or preventing our ability to provide our software solutions until equivalent technology is eitherdeveloped by us or, if available, identified, obtained and integrated. In addition, errors or defects in third-party hardware or software used in oursoftware solutions could result in errors or a failure, which could damage our reputation, impede our ability to provide our platform or processinformation, and adversely affect our business and results of operations.We face exposure to foreign currency exchange rate fluctuations that could harm our results of operations.We conduct transactions, particularly intercompany transactions, in currencies other than the U.S. dollar, primarily the British pound and theEuro. As we grow our international operations, we expect the amount of our revenues that are denominated in foreign currencies to increase in thefuture. Accordingly, changes in the value of foreign currencies relative to the U.S. dollar could affect our revenue and operating results due totransactional and translational remeasurements that are reflected in our results of operations. As a result of such foreign currency exchange ratefluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent thatfluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our investors, thetrading price of our common stock could be adversely affected.Additionally, as a result of Brexit, global markets and foreign currencies were adversely impacted. In particular, the value of the Britishpound declined as compared to the U.S. dollar and other currencies. This volatility in foreign currencies is expected to continue as the U.K.negotiates and executes its exit from the EU, but it is uncertain over what time period this will occur. A significantly weaker British poundcompared to the U.S. dollar could have a negative effect on our business, financial condition and results of operations.We do not currently maintain a program to hedge transactional exposures in foreign currencies. However, in the future, we may usederivative instruments, such as foreign currency forward and option contracts, to hedge exposures to fluctuations in foreign currency exchangerates. The use of such hedging activities may not offset any or more than a portion of the adverse financial effects of unfavorable movements inforeign exchange rates over the limited time the hedges are in place. Moreover, the use of hedging instruments may introduce additional risks if weare unable to structure effective hedges with such instruments.28 We are subject to governmental export and import controls that could impair our ability to compete in international markets due tolicensing requirements and subject us to liability if we are not in full compliance with applicable laws.Our solutions are subject to export controls, including the Commerce Department’s Export Administration Regulations and various economicand trade sanctions regulations established by the Treasury Department’s Office of Foreign Assets Controls. Obtaining the necessaryauthorizations, including any required license, for a particular export or sale may be time-consuming, is not guaranteed and may result in the delayor loss of sales opportunities. The U.S. export control laws and economic sanctions laws prohibit the export, re-export or transfer of specificproducts and services to U.S. embargoed or sanctioned countries, governments and persons. Even though we take precautions to prevent oursolutions from being provided to U.S. sanctions targets, our solutions could be sold by resellers or could be used by persons in sanctionedcountries despite such precautions. Failure to comply with the U.S. export control, sanctions and import laws could have negative consequences,including government investigations, penalties and reputational harm. We and our employees could be subject to civil or criminal penalties,including the possible loss of export or import privileges, fines, and, in extreme cases, the incarceration of responsible employees or managers. Inaddition, if our resellers fail to obtain appropriate import, export or re-export licenses or authorizations, we may also be adversely affected throughreputational harm and penalties.In addition, various countries regulate the import of encryption technology, including through import permitting/licensing requirements, andhave enacted laws that could limit our ability to distribute our solutions or could limit our customers’ ability to implement or access our solutions inthose countries. Changes in our solutions or changes in export, sanctions and import regulations may create delays in the introduction and sale ofour solutions in international markets, prevent our customers with international operations from accessing our solutions or, in some cases,preventing the export or import of our solutions to some countries, governments or persons altogether. Any change in export or import regulations,economic sanctions or related laws, shift in the enforcement or scope of existing regulations, or change in the countries, governments, persons ortechnologies targeted by such regulations, could result in decreased use of our solutions, or in our decreased ability to export or sell our solutionsto existing or potential customers with international operations. Any decreased use of our solutions or limitation on our ability to export or sell oursolutions would likely adversely affect our business, financial condition and results of operations.29 The nature of our business requires the application of complex revenue and expense recognition rules and the current legislative andregulatory environment affecting generally accepted accounting principles is uncertain. Significant changes in current principles couldaffect our financial statements going forward and changes in financial accounting standards or practices may cause adverse, unexpectedfinancial reporting fluctuations and harm our operating results.The accounting rules and regulations that we must comply with are complex and subject to interpretation by the FASB, the SEC and variousbodies formed to promulgate and interpret appropriate accounting principles. Recent actions and public comments from the FASB and the SEChave focused on the integrity of financial reporting and internal controls. In addition, many companies’ accounting policies are being subject toheightened scrutiny by regulators and the public. Further, the accounting rules and regulations are continually changing in ways that couldmaterially impact our financial statements. For example, in May 2014, the FASB issued Accounting Standards Update, or ASU, No. 2014-09,Revenue from Contracts with Customers (Topic 606), as amended, which will supersede nearly all existing revenue recognition guidance. Althoughthe new standard permits early adoption as early as January 1, 2017, the effective date of the new revenue standard was January 1, 2018. Thenew standard permitted adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modifiedretrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providingcertain additional disclosures. We will adopt the new revenue guidance in the first quarter of 2018 using the full retrospective method to restateeach prior reporting period presented. We are currently assessing the impact of the new revenue guidance on our arrangements; we anticipate thisstandard will have a material impact on our consolidated financial statements. We currently believe that the new guidance will impact the amountand timing of incremental costs of obtaining a contract, such as sales commissions. We generally do not pay sales commissions upon contractrenewal. Accordingly, under the new revenue guidance, the sales commissions will be recognized over an estimated period of benefit rather thanover the non-cancelable term under current guidance. The new guidance is also expected to impact our on-premise solutions subject to currentsoftware revenue recognition guidance, as we may be required to recognize as revenue a significant portion of the contract consideration upondelivery of the software compared to the current practice of recognizing the contract consideration ratably over time for certain arrangements. Thenew guidance will also require incremental disclosures of our revenue arrangements. We are in process of quantifying the impact of thesechanges. Adoption of this standard will also require changes to our business processes, systems and controls to support the new revenuerecognition guidance. We are in the process of identifying and implementing such changes.We cannot predict the impact of future changes to accounting principles or our accounting policies on our financial statements goingforward, which could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before theannouncement of the change. In addition, if we were to change our critical accounting estimates, including those related to the recognition oflicense revenue and other revenue sources, our operating results could be significantly affected.Incorrect or improper implementation or use of our solutions could result in customer dissatisfaction and negatively affect our business,results of operations, financial condition, and growth prospects.Our platform is deployed in a wide variety of technology environments and into a broad range of complex workflows. Our platform has beenintegrated into large-scale, enterprise-wide technology environments, and specialized use cases, and our success depends on our ability toimplement our platform successfully in these environments. We often assist our customers in implementing our platform, but many customersattempt to implement even complex deployments themselves or use a third-party service firm. If we or our customers are unable to implement ourplatform successfully, or are unable to do so in a timely manner, customer perceptions of our platform and company may be impaired, ourreputation and brand may suffer, and customers may choose not to renew or expand the use of our platform.Our customers and third-party resellers may need training in the proper use of our platform to maximize its potential. If our platform is notimplemented or used correctly or as intended, including if customers input incorrect or incomplete financial data into our platform, inadequateperformance may result. Because our customers rely on our platform to manage their financial close and other financial tasks, the incorrect orimproper implementation or use of our platform, our failure to train customers on how to efficiently and effectively use our platform, or our failure toprovide adequate product support to our customers, may result in negative publicity or legal claims against us. Also, as we continue to expand ourcustomer base, any failure by us to properly provide these services will likely result in lost opportunities for additional subscriptions to our platform.30 Any failure to offer high-quality product support may adversely affect our relationships with our customers and our financial results.In deploying and using our solutions, our customers depend on our support services team to resolve complex technical and operationalissues. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for product support. We alsomay be unable to modify the nature, scope and delivery of our product support to compete with changes in product support services provided byour competitors. Increased customer demand for product support, without corresponding revenue, could increase costs and adversely affect ouroperating results. Our sales are highly dependent on our business reputation and on positive recommendations from our existing customers. Anyfailure to maintain high-quality product support, or a market perception that we do not maintain high-quality product support, could adversely affectour reputation, our ability to sell our solutions to existing and prospective customers, our business, operating results, and financial position.If the market for SaaS solutions develops more slowly than we expect or declines, our business would be adversely affected.The market for SaaS solutions is less mature than the market for on-premise software applications, and the adoption rate of SaaS solutionsmay be slower at companies in industries with heightened data security interests or business practices requiring highly customizable applicationsoftware. Many organizations have invested substantial personnel and financial resources to integrate traditional on-premise solutions into theirbusinesses, and therefore may be reluctant or unwilling to purchase SaaS solutions. In addition, some organizations have been reluctant to usecloud-based solutions because they have concerns regarding the risks associated with the reliability or security of the technology delivery modelassociated with these solutions. Because our solutions involve the aggregation, storage and use of confidential information and related data,including highly confidential financial data, some customers may be reluctant or unwilling to migrate to our cloud-based solutions.It is difficult to predict customer adoption rates and demand for our software solutions, the future growth rate and size of the market or theentry of competitive products or services. The expansion of the SaaS solutions market depends on a number of factors, including the cost,performance and perceived value associated with SaaS, as well as the ability of SaaS providers to address data security and privacy concerns.Government agencies have adopted, or may adopt, laws and regulations regarding the collection and use of personal information obtained fromconsumers and other individuals, or may seek to access information on our platform, either of which may reduce the overall demand for ourplatform. If we or other SaaS providers experience data security incidents, loss of customer data, disruptions in delivery, or other problems, themarket for SaaS solutions, including our platform, may be negatively affected. If SaaS solutions do not continue to achieve market acceptance, orthere is a reduction in demand for SaaS solutions caused by a lack of customer acceptance, technological challenges, data security or privacyconcerns, governmental regulation, competing technologies and products, or decreases in information technology spending, it would result indecreased revenue and our business would be adversely affected.Unfavorable conditions in our industry or the global economy could limit our ability to grow our business and negatively affect ouroperating results.Our operating results may vary based on the impact of changes in our industry or the global economy on us or our customers. The revenuegrowth and potential profitability of our business depend on demand for business software applications and services generally and for accountingand finance systems in particular. Weak economic conditions affect the rate of accounting and finance and information technology spending andcould adversely affect our customers’ or potential customers’ ability or willingness to purchase our cloud platform, delay purchasing decisions,reduce the value or duration of their subscription contracts, or affect attrition rates, all of which could adversely affect our operating results. Ifeconomic conditions deteriorate, our customers and prospective customers may elect to decrease their accounting and finance and informationtechnology budgets, which would limit our ability to grow our business and negatively affect our operating results.Changes in laws and regulations related to the internet and cloud computing or changes to internet infrastructure may diminish thedemand for our solutions, and could have a negative impact on our business.The future success of our business depends upon the continued use of the internet as a primary medium for commerce, communication,and business applications. Federal, state, or foreign government bodies or agencies have in the past adopted, and may in the future adopt, laws orregulations affecting the use of the internet as a commercial medium. Regulators in some industries have also adopted, and may in the futureadopt regulations or interpretive positions regarding the use of SaaS and cloud computing solutions. For example, some financial servicesregulators have31 imposed guidelines for the use of cloud computing services that mandate specific controls or require financial services enterprises to obtainregulatory approval prior to utilizing such software. Changes in these laws or regulations could require us to modify our solutions in order to complywith these changes. In addition, government agencies or private organizations have imposed and may impose additional taxes, fees, or othercharges for accessing the internet or commerce conducted via the internet. These laws or charges could limit the growth of internet-relatedcommerce or communications generally, or result in reductions in the demand for internet-based solutions and services such as ours. In addition,the use of the internet as a business tool could be adversely affected due to delays in the development or adoption of new standards and protocolsto handle increased demands of internet activity, security, reliability, cost, ease-of-use, accessibility, and quality of service. The performance ofthe internet and its acceptance as a business tool has been adversely affected by “viruses,” “worms,” and similar malicious programs and theinternet has experienced a variety of outages and other delays as a result of damage to portions of its infrastructure. If the use of the internet isadversely affected by these issues, demand for our solutions could decline. The adoption of any laws or regulations adversely affecting the growth, popularity or use of the Internet, including laws impacting Internetneutrality, could decrease the demand for our products and increase our operating costs. The current legislative and regulatory landscaperegarding the regulation of the Internet and, in particular, Internet neutrality, in the United States is subject to uncertainty. The FederalCommunications Commission passed Open Internet rules in February 2015, effective in June 2015, generally providing for Internet neutrality withrespect to fixed and mobile broadband Internet service. On December 14, 2017, the Federal Communications Commission voted to repeal OpenInternet rules generally providing for Internet neutrality with respect to fixed and mobile broadband Internet service regulations and return to a “light-touch” regulatory framework. However, the repeal has not yet taken effect and a number of parties have already stated their intent to appeal thisorder, thus, the future impact of such repeal and any challenge thereto remains uncertain. Any changes in the legislative and regulatory landscaperegarding Internet neutrality, or otherwise regarding the regulation of the Internet, could harm our business.We provide service level commitments under our customer contracts, and if we fail to meet these contractual commitments, ourrevenues could be adversely affected.Our customer agreements typically provide service level commitments. If we are unable to meet the stated service level commitments orsuffer extended periods of unavailability for our applications, we may be contractually obligated to provide these customers with service credits,refunds for prepaid amounts related to unused subscription services, or we could face contract terminations. Our revenues could be significantlyaffected if we suffer unscheduled downtime that exceeds the allowed downtimes under our agreements with our customers. Any extended serviceoutages could adversely affect our reputation, revenues and operating results.Seasonality could cause our operating results and financial metrics to fluctuate from quarter to quarter and make them more difficult topredict.We typically add fewer customers in the first quarter of the year than other quarters. We also experience a higher volume of sales at the endof each quarter and year, which is often the result of buying decisions by our customers. Seasonality may be reflected to a much lesser extent,and sometimes may not be immediately apparent, in our revenue, due to the fact that we recognize subscription revenue over the term of ouragreements. We may also increase expenses in a period in anticipation of future revenues. Changes in the number of customers and users indifferent periods will cause fluctuations in our financial metrics and, to a lesser extent, revenues. Those changes and fluctuations in our expenseswill affect our results on a quarterly basis, and will make forecasting our future operating results and financial metrics difficult.Our international operations subject us to potentially adverse tax consequences.We report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. Our intercompanyrelationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxingauthorities may disagree with our determinations as to the value of assets sold or acquired or income and expenses attributable to specificjurisdictions. If such a disagreement were to occur, and our position were not sustained, we could be required to pay additional taxes, interest andpenalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of ouroperations. We believe that our financial statements reflect adequate reserves to cover such a contingency, but there can be no assurances inthat regard.32 The enactment of legislation implementing changes in the U.S. taxation of international business activities or the adoption of other taxreform policies could materially impact our financial position and results of operations.Recent changes to U.S. tax laws, including limitations on the ability of taxpayers to claim and utilize foreign tax credits, as well as changesto U.S. tax laws that may be enacted in the future, could impact the tax treatment of our foreign earnings. Due to expansion of our internationalbusiness activities, any changes in the U.S. taxation of such activities may increase our worldwide effective tax rate and adversely affect ourfinancial position and results of operations.In December 2017, the U.S. Congress passed and the President signed legislation commonly referred to as the Tax Cuts and Jobs Act (“theTax Act”), which contains many significant changes to the U.S. tax laws. The consequences of these changes, including whether and how state,local and foreign jurisdictions will react to such changes, have not yet been determined. Changes in corporate tax rates, the realizability of the netdeferred tax assets relating to our U.S. operations, the taxation of foreign earnings, and the deductibility of expenses contained in the Tax Act orother tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in thecurrent or future taxable years, and could increase our future U.S. tax expense. Furthermore, changes to the taxation of undistributed foreignearnings could change our future intentions regarding reinvestment of such earnings. The foregoing items could have an adverse effect on ouroperating results, cash flow, or financial conditionOur ability to use our net operating losses to offset future taxable income may be subject to limitations.At December 31, 2017, we had federal and state net operating loss carryforwards (“NOLs”), of $122.3 million and $60.3 million, respectively.In general, under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”) a corporation that undergoes an “ownership change”is subject to limitations on its ability to utilize its NOLs to offset future taxable income. Our existing NOLs may be subject to limitations arisingfrom previous ownership changes, and if we undergo an ownership change, our ability to utilize NOLs could be further limited by Section 382 of theCode. Future changes in our stock ownership, some of which are outside of our control, could result in an ownership change under Section 382 ofthe Code. Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to limitations. There is also a riskthat due to regulatory changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire orotherwise be unavailable to offset future income tax liabilities. For these reasons, we may not be able to realize a tax benefit from the use of ourNOLs, whether or not we attain profitability. The Tax Act includes changes to the U.S. federal corporate income tax rate, and our NOLs and otherdeferred tax assets have been revalued at the newly enacted rate. The revaluation did not have a material impact on our consolidated balancesheet and consolidated statement of operations because we currently maintain a full valuation allowance on our U.S. deferred tax assets.Taxing authorities may successfully assert that we should have collected, or in the future should collect, sales and use, value-added orsimilar taxes, and we could be subject to liability with respect to past or future sales, which could adversely affect our results ofoperations.Sales and use, value-added and similar tax laws and rates vary greatly by jurisdiction and are subject to change from time to time. Somejurisdictions in which we do not collect such taxes may assert that such taxes are applicable, which could result in tax assessments, penaltiesand interest, and we may be required to collect such taxes in the future. Such tax assessments, penalties and interest or future requirements mayadversely affect our results of operations.We might require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all.We intend to continue to make investments to support our business growth and may require additional funds to respond to businesschallenges, including the need to develop new features or enhance our existing solutions, improve our operating infrastructure or acquirecomplementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If weraise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution,and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debtfinancing secured by us in the future could involve restrictive covenants relating to our capital raising activities and other financial and operationalmatters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions.In addition, we may not be able to obtain additional financing on terms favorable to us, or at all. If we are unable to obtain adequate financing orfinancing on terms satisfactory to us, when we require it, our ability to continue to support our business growth and to respond to businesschallenges could be significantly impaired.33 Natural disasters and other events beyond our control could harm our business.Natural disasters or other catastrophic events may cause damage or disruption to our operations, international commerce and the globaleconomy, and thus could have a strong negative effect on us. Our business operations are subject to interruption by natural disasters, fire, powershortages, pandemics and other events beyond our control. Although we maintain crisis management and disaster response plans, such eventscould make it difficult or impossible for us to deliver our solutions to our customers, and could decrease demand for our solutions. The majority ofour research and development activities, corporate headquarters, information technology systems and other critical business operations arelocated in California, which has experienced major earthquakes in the past. Significant recovery time could be required to resume operations andour financial condition and operating results could be harmed in the event of a major earthquake or catastrophic event.If our goodwill or intangible assets become impaired, we may be required to record a significant charge to earnings.We review our goodwill and intangible assets for impairment when events or changes in circumstances indicate the carrying value may notbe recoverable. Goodwill is required to be tested for impairment at least annually. At December 31, 2017, we had goodwill and intangible assetswith a net book value of $225.9 million related to the 2013 Acquisition and the Runbook Acquisition. An adverse change in market conditions,particularly if such change has the effect of changing one of our critical assumptions or estimates, could result in a change to the estimation of fairvalue that could result in an impairment charge to our goodwill or intangible assets. Any such charges may have a material negative impact on ouroperating results.Risks Related to Ownership of our Common StockThe market price of our common stock may be volatile, and you could lose all or part of your investment.The market price of our common stock since our initial public offering has been and may continue to be subject to wide fluctuations inresponse to various factors, some of which are beyond our control and may not be related to our operating performance. Factors that could causefluctuations in the market price of our common stock include the following: •actual or anticipated fluctuations in our operating results; •the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections; •failure of securities analysts to initiate or maintain coverage of our company, changes in financial estimates by any securitiesanalysts who follow our company or our failure to meet these estimates or the expectations of investors; •ratings changes by any securities analysts who follow our company; •announcements by us or our competitors of significant technical innovations, acquisitions, strategic relationships, joint ventures, orcapital commitments; •changes in operating performance and stock market valuations of other technology companies generally, or those in our industry inparticular; •price and volume fluctuations in the overall stock market from time to time, including as a result of trends in the economy as a whole; •changes in accounting standards, policies, guidelines, interpretations or principles; •actual or anticipated developments in our business or our competitors’ businesses or the competitive landscape generally; •developments or disputes concerning our intellectual property, or our products or third-party proprietary rights; •announced or completed acquisitions of businesses or technologies by us or our competitors; •new laws or regulations, or new interpretations of existing laws or regulations applicable to our business; •any major change in our board of directors or management; •sales of shares of our common stock by us or our stockholders;34 •lawsuits threatened or filed against us; and •other events or factors, including those resulting from war, incidents of terrorism, or responses to these events.In addition, the stock markets, and in particular the market on which our common stock is listed, have experienced extreme price andvolume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock pricesof many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In thepast, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved insecurities litigation, it could subject us to substantial costs, divert resources and the attention of management from operating our business, andadversely affect our business, results of operations, financial condition and cash flows.The Company is controlled by certain of our Principal Stockholders, whose interests may differ from those of other stockholders.At December 31, 2017, our Principal Stockholders beneficially owned, in the aggregate, approximately 54% of our outstanding commonstock and directors affiliated with our Principal Stockholders comprise a majority of our board of directors. Further, we entered into a Stockholders’Agreement with the Principal Stockholders which provides that the Principal Stockholders are entitled to designate members of our board ofdirectors. We anticipate that the parties to the Stockholders’ Agreement will agree to vote for these nominees as well as other directorsrecommended by our nominating and corporate governance committee.Under the Stockholders’ Agreement and subject to our amended and restated certificate of incorporation and amended and restated bylawsand applicable law, for so long as the Principal Stockholders collectively own or hold of record, directly or indirectly, in the aggregate at least 40%of their collective “Post-IPO Shares” (as defined in the Stockholders’ Agreement), as adjusted for any reorganization, recapitalization, stockdividend, stock split, reverse stock split or similar changes in our capitalization, the following actions will require the approval of our board ofdirectors, including the affirmative vote of at least two directors designated by Silver Lake Sumeru: •any voluntary liquidation, winding up or dissolution or any action relating to a voluntary bankruptcy, reorganization or recapitalizationof the company or its subsidiaries; •certain dispositions of assets in excess of $50 million or entry into joint ventures requiring a capital contribution in excess of $50million, in each case, by the company or its subsidiaries; •fundamental changes in the nature of the company’s or its subsidiaries’ existing lines of business or the entry into a new significantline of business; •any amendments to the company’s amended and restated certificate of incorporation and amended and restated bylaws; •incurrence of indebtedness in excess of $150 million; •appointment or termination of the Chief Executive Officer; and •change of control transactions.At December 31, 2017, the Principal Stockholders have sufficient voting power to determine the outcome of all matters requiring stockholderapproval, including mergers and other material transactions, and are able to cause or prevent a change in the composition of our board of directorsor a change in control of our company that could deprive our stockholders of an opportunity to receive a premium for their common stock as part ofa sale of our company and might ultimately affect the market price of our common stock.Further, our amended and restated certificate of incorporation provides that, to the fullest extent permitted by law, the doctrine of “corporateopportunity” will not apply to Silver Lake Sumeru, Iconiq, their respective affiliates or the directors they designate, pursuant to their rights under theStockholders’ Agreement in a manner that would prohibit them from investing in competing businesses or doing business with our partners orcustomers. Accordingly, these directors will have the rights to pursue business opportunities that may be of interest to the company and whichthey would otherwise need to provide to the company.35 Although we do not expect to rely on the “controlled company” exemption, we are a “controlled company” within the meaning of thestock exchange rules and we qualify for exemptions from certain corporate governance requirements.Because our Principal Stockholders collectively own a majority of our outstanding common stock, we are considered a “controlled company”as that term is set forth in the stock exchange rules. Under these rules, a company of which more than 50% of the voting power is held by anotherperson or group of persons acting together is a “controlled company” and may elect not to comply with certain stock exchange rules regardingcorporate governance, including: •the requirement that a majority of its board of directors consist of independent directors; •the requirement that its nominating and corporate governance committee be composed entirely of independent directors with a writtencharter addressing the committee’s purpose and responsibilities; and •the requirement that its compensation committee be composed entirely of independent directors with a written charter addressing thecommittee’s purpose and responsibilities.These requirements will not apply to us as long as we remain a “controlled company.” Although we qualify as a “controlled company,” we donot expect to rely on this exemption and intend to fully comply with all corporate governance requirements under the stock exchange rules.However, if we were to utilize some or all of these exemptions, you may not have the same protections afforded to stockholders of companies thatare subject to all of the stock exchange rules regarding corporate governance.Substantial future sales of shares of our common stock could cause the market price of our common stock to decline.The market price of our common stock could decline as a result of substantial sales of our common stock, particularly sales by ourdirectors, executive officers and significant stockholders, a large number of shares of our common stock becoming available for sale or theperception in the market that holders of a large number of shares intend to sell their shares.Under the Stockholders’ Agreement, each of Iconiq, Ms. Tucker and Mr. Spanicciati have agreed, subject to certain limited exceptions, notto transfer, sell, exchange, assign, pledge, hypothecate, convey or otherwise dispose of or encumber any shares of our common stock without theconsent of Silver Lake Sumeru until the earlier of (i) two years following the completion of our initial public offering, or November 2, 2018, and (ii)Silver Lake Sumeru’s reduction of its holdings of common stock following our initial public offering by 50%; provided, however, that each of Ms.Tucker and Mr. Spanicciati has the right to sell a number of shares equal to up to 1% of the total outstanding shares of our common stockannually pursuant to Rule 144 of the Securities Act. In November 2017, we filed a shelf registration statement on Form S-3 that registered the saleof 33,738,329 shares of our common stock then held by our Principal Stockholders, from time to time, in secondary offerings. In December 2017,certain of our Principal Stockholders sold an aggregate of 4,500,000 shares under the registration statement and the remaining 29,238,329 sharesregistered under the registration statement may be offered and sold without restriction under the Securities Act. Such shares may be offered fromtime to time in the open market, in block trades, in underwritten offerings or in any other transaction described in the related prospectus. All sharescovered by the registration statement are immediately tradeable unless transferred to an affiliate of the CompanySales of our common stock by our current stockholders may make it more difficult for us to sell equity securities in the future at a time andat a price that we deem appropriate. These sales also could cause the market price of our common stock to decline and make it more difficult foryou to sell shares of our common stock.36 Provisions of our corporate governance documents could make an acquisition of the company more difficult and may impede attemptsby our stockholders to replace or remove our current management, even if beneficial to our stockholders.Our amended and restated certificate of incorporation and amended and restated bylaws and the Delaware General Corporation Law (the“DGCL”) contain provisions that could make it more difficult for a third-party to acquire us, even if doing so might be beneficial to our stockholders.Among other things: •we have authorized but unissued shares of undesignated preferred stock, the terms of which may be established and the shares ofwhich may be issued without stockholder approval, and which may include supermajority voting, special approval, dividend, or otherrights or preferences superior to the rights of stockholders; •we have a classified board of directors with staggered three-year terms; •stockholder action by written consent will be prohibited from and after the date on which the Principal Stockholders beneficially own,in the aggregate, less than 35% in voting power of our stock entitled to vote generally in the election of directors; •for as long as the Principal Stockholders beneficially own, in the aggregate, at least 40% in voting power of our stock entitled to votegenerally in the election of directors, any amendment, alteration, rescission or repeal of our amended and restated bylaws or ouramended and restated certificate of incorporation by our stockholders will require the affirmative vote of 60% of the voting power ofour stock entitled to vote thereon, voting together as a single class and at any time when the Principal Stockholders beneficially own,in the aggregate, less than 40% in voting power of our stock entitled to vote generally in the election of directors, any amendment,alteration, rescission or repeal of our amended and restated bylaws or of certain provisions of our amended and restated certificate ofincorporation by our stockholders will require the affirmative vote of the holders of at least 75% of the voting power of our stockentitled to vote thereon, voting together as a single class outstanding; and •stockholders are required to comply with advance notice requirements for nominations for elections to our board of directors or forproposing matters that can be acted upon by stockholders at stockholder meetings; provided, however, that such advance noticeprocedures will not apply to the Principal Stockholders at any time such person or entity owns in the aggregate at least 10% of thevoting power of our stock entitled to vote generally in the election of directors.Further, as a Delaware corporation, we are also subject to provisions of Delaware law, which may impair a takeover attempt that ourstockholders may find beneficial. These anti-takeover provisions and other provisions under Delaware law could discourage, delay or prevent atransaction involving a change in control of the company, including actions that our stockholders may deem advantageous, or negatively affect thetrading price of our common stock. These provisions could also discourage proxy contests and make it more difficult for you and otherstockholders to elect directors of your choosing and to cause us to take other corporate actions you desire.We are an “emerging growth company” and we cannot be certain if the reduced disclosure requirements applicable to emerging growthcompanies will make our common stock less attractive to investors.We are an “emerging growth company,” as defined in the federal securities laws, and we have taken advantage of exemptions from variousreporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, notbeing required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligationsregarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbindingadvisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We cannot predictif investors will find our common stock less attractive because we have relied on these exemptions. If some investors find our common stock lessattractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile. We will remain an“emerging growth company” until the last day of the fiscal year following the five-year anniversary of the completion of our initial public offering,although if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the end of the second quarter of a fiscalyear prior to the five-year anniversary, we would cease to be an “emerging growth company” as of the following December 31.37 The requirements of being a public company may strain our resources, divert management’s attention, and affect our ability to attractand retain executive management and qualified board members.As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “ExchangeAct”) the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the listing requirements of theexchanges and other markets upon which our common stock is listed, and other applicable securities rules and regulations. Compliance with theserules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming, or costly, andincrease demand on our systems and resources, particularly after we are no longer an “emerging growth company.” The Exchange Act requires,among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Actrequires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order tomaintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard,significant resources and management oversight may be required. We are required to disclose changes made in our internal control andprocedures on a quarterly basis and are required to furnish a report by management on, among other things, the effectiveness of our internalcontrol over financial reporting for the fiscal year ended December 31, 2017. However, our independent registered public accounting firm will not berequired to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 until the date we are no longer an“emerging growth company.” As a result of the complexity involved in complying with the rules and regulations applicable to public companies, ourmanagement’s attention may be diverted from other business concerns, which could adversely affect our business and operating results. Althoughwe have already hired additional employees to assist us in complying with these requirements, we may need to hire more employees in the futureor engage outside consultants, which will increase our operating expenses.In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure are creating uncertainty forpublic companies, increasing legal and financial compliance costs, and making some activities more time-consuming. These laws, regulations,and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practicemay evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regardingcompliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest substantialresources to comply with evolving laws, regulations, and standards, and this investment may result in increased general and administrativeexpenses and a diversion of management’s time and attention from business operations to compliance activities. If our efforts to comply with newlaws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their applicationand practice, regulatory authorities may initiate legal proceedings against us and our business may be adversely affectedAs a result of increased disclosure of information in the filings required in a public company, our business and financial condition hasbecome more visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If such claimsare successful, our business and operating results could be adversely affected, and even if the claims do not result in litigation or are resolved inour favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and adverselyaffect our business and operating results.We do not intend to pay dividends on our common stock so any returns will be limited to changes in the value of our common stock.We have never declared or paid any cash dividends on our common stock. We currently anticipate that we will retain future earnings for thedevelopment, operation, and expansion of our business, and do not anticipate declaring or paying any cash dividends for the foreseeablefuture. Any return to stockholders will therefore be limited to the increase, if any, of our stock price, which may never occur.If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stockprice and trading volume could decline.The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish aboutus or our business. If few securities analysts commence coverage of us, or if industry analysts cease coverage of us, the trading price for ourcommon stock would be negatively affected. If one or more of the analysts who cover us downgrade our common stock or publish inaccurate orunfavorable research about our business, our common stock price would likely decline. If one or more of these analysts cease coverage of us orfail to publish reports on us regularly, demand for our common stock could decrease, which might cause our common stock price and tradingvolume to decline.38 Our amended and restated bylaws designate a state or federal court located within the State of Delaware as the exclusive forum forcertain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicialforum for disputes with us.Pursuant to our amended and restated bylaws, unless we consent in writing to the selection of an alternative forum, the sole and exclusiveforum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by anyof our directors, officers or other employees to us or our stockholders, (3) any action asserting a claim against us arising pursuant to any provisionof the DGCL, or (4) any action asserting a claim against us that is governed by the internal affairs doctrine shall be a state or federal court locatedwithin the State of Delaware, in all cases subject to the court’s having personal jurisdiction over indispensable parties named as defendants. Anyperson or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented tothis provision. The forum selection clause in our amended and restated bylaws may have the effect of discouraging lawsuits against us or ourdirectors and officers and may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us. Item 1B.Unresolved Staff CommentsNone.Item 2.PropertiesOur principal executive offices are located in Los Angeles, California where we occupy approximately 89,000 square feet of space under alease that expires in January 2024. We also occupy additional leased offices located in Chicago, Illinois; Atlanta, Georgia; New York, New York;London, the United Kingdom; Melbourne, Australia; Sydney, Australia; Paris, France; Johannesburg, South Africa; Frankfurt, Germany; KualaLumpur, Malaysia; Vancouver, Canada; Ede, Netherlands; Warsaw, Poland, Bucharest, Romania, and Singapore. We believe that our propertiesare generally suitable to meet our needs for the foreseeable future. In addition, to the extent we require additional space in the future, we believethat it would be readily available on commercially reasonable terms.Item 3.Legal ProceedingsFrom time to time, we may be subject to legal proceedings arising in the ordinary course of business. In addition, from time to time, thirdparties may assert intellectual property infringement claims against us in the form of letters and other forms of communication. As of the date ofthis Annual Report on Form 10-K for the year ended December 31, 2017, we are not a party to any litigation the outcome of which, if determinedadversely to us, would individually or in the aggregate be reasonably expected to have a material adverse effect on our results of operations,prospects, cash flows, financial position or brand.Item 4.Mine Safety DisclosuresNot applicable. 39 PART II Item 5.Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity SecuritiesMarket for Our Common Stock and Related Stockholder MattersOur common stock has been traded on the NASDAQ Global Select Market under the symbol “BL” since October 28, 2016. Prior to thattime, there was no public market for our common stock. The following table sets forth, for the periods indicated, the high and low intraday salesprices for our common stock as reported on the NASDAQ Global Select Market. 2017 2016 High Low High Low First Quarter $31.40 $25.95 * * Second Quarter $38.83 $28.97 * * Third Quarter $40.28 $28.79 * * Fourth Quarter $39.00 $32.67 $28.77 $21.66 *Prior to October 28, 2016 there was no public marketfor our common stock. On March 1, 2018, the last reported sales price on the NASDAQ Global Select Market for our common stock was $43.81 per share.Holders of RecordAt March 1, 2018, there were 29 shareholders of record. The number of record holders does not include beneficial holders who hold theirshares in “street name,” meaning that the shares are held for their accounts by a broker or other nominee. Accordingly, we believe that the totalnumber of beneficial holders is higher than the number of our shareholders of record.Dividend PolicyWe have never declared or paid, any cash dividends on our common stock. We currently intend to retain all of our future earnings, if any, tofinance our operations and do not anticipate paying any cash dividends on our common stock in the foreseeable future. Any future determinationas to the declaration and payment of dividends will be at the discretion of our board of directors and will depend on then-existing conditions,including our financial condition, operating results, contractual restrictions, capital requirements, business prospects, and other factors our board ofdirectors may deem relevant.40 Stock Price Performance GraphThis performance graph shall not be deemed “soliciting material” or to be “filed” with the Securities and Exchange Commission, or the SEC, forpurposes of Section 18 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, or otherwise subject to the liabilities under thatSection, and shall not be deemed to be incorporated by reference into any of our filings under the Securities Act of 1933, as amended, or theSecurities Act.The following graph compares (i) the cumulative total stockholder return on our common stock from October 28, 2016 (the date ourcommon stock commenced trading on the NASDAQ Global Select Market) through December 31, 2017 with (ii) the cumulative total return of theS&P 500 Index and the NASDAQ Computer & Data Processing Index over the same period, assuming the investment of $100 in our commonstock and in both of the other indices on October 28, 2016 and the reinvestment of dividends.

Prior to such Acquisition, we had no significant operations. As a result, theconsolidated financial statements for the periods from January 1, 2013 to September 2, 2013 are presented as BlackLine Systems, Inc., which werefer to as the Predecessor, and all subsequent periods are presented as BlackLine, Inc., which we refer to as the Successor. The Successorfinancial statements reflect a new basis of accounting as a result of the 2013 Acquisition and therefore are not comparable to the Predecessorfinancial statements. We refer to the period from January 1, 2013 to September 2, 2013 as the 2013 Predecessor Period and the period fromSeptember 3, 2013 to December 31, 2013 as the 2013 Successor Period.The consolidated statements of operations data for the years ended December 31, 2017, 2016, and 2015 and the consolidated balancesheet data at December 31, 2017 and 2016 are derived from, and qualified by reference to, our audited financial statements included elsewhere inthis Annual Report on Form 10-K. The consolidated statements of operations data for the year ended December 31, 2014 and the 2013 Successorperiods and the consolidated balance sheet data at December 31, 2015, 2014, and 2013 are derived from our audited financial statements notincluded in this Annual Report on Form 10-K.

See Part I, “Special Note Regarding Forward-Looking Statements” for a discussion ofthe forward-looking statements contained below and Part I, Item 1A, “Risk Factors” for a discussion of certain risks that could cause our actualresults to differ materially from the results anticipated in such forward-looking statements.OverviewWe have created a comprehensive cloud-based software platform designed to transform and modernize accounting and finance operationsfor organizations of all types and sizes. Our secure, scalable platform supports critical accounting processes such as the financial close, accountreconciliations, intercompany accounting, and controls assurance. By introducing software to automate these processes and to enable them tofunction continuously, we empower our customers to improve the integrity of their financial reporting, increase efficiency in their accounting andfinance processes and enhance real-time visibility into their operations.At December 31, 2017, we had approximately 2,200 customers and approximately 196,000 users in over 150 countries exclusive of on-premise software. Additionally, we continue to build strategic relationships with technology vendors, professional services firms, business processoutsourcers, and resellers.We are a holding company and conduct our operations through our wholly-owned subsidiary, BlackLine Systems, Inc. (“BlackLineSystems”). BlackLine Systems funded its business with investments from our founder and cash flows from operations until September 3,2013. On September 3, 2013, we acquired BlackLine Systems, and Silver Lake Sumeru and Iconiq acquired a controlling interest in us, which werefer to as the “2013 Acquisition.” The 2013 Acquisition was accounted for as a business combination under GAAP and resulted in a change inaccounting basis as of the date of the 2013 Acquisition.Our platform consists of eight core cloud-based products, including Transaction Matching, Account Reconciliations, Consolidation IntegrityManager, Daily Reconciliations, Journal Entry, Variance Analysis, Task Management and Insights. Customers typically purchase these productsin packages that we refer to as solutions, but they have the option to purchase these products individually. Current solutions include BalanceSheet Integrity, Close Process Management, Accounting Process Automation, Finance Transformation, Intercompany Hub and Smart Close.We derived approximately 95% of our revenue from subscriptions to our cloud-based software platform and approximately 5% fromprofessional services for the year ended December 31, 2017. The majority of subscriptions are sold through one-year non-cancellable contracts,with a growing percentage of subscriptions sold through three-year contracts. We price our subscriptions based on a number of factors, primarilythe number of users having access to the products and the number of products purchased by the customer. Subscription revenue is recognizedratably over the term of the customer agreement. The first year of subscription fees are typically payable within 30 days after execution of acontract, and thereafter upon renewal.Professional services consist of implementation and consulting services. Although our platform is ready to use immediately after a newcustomer has access to it, we typically help customers implement our solutions for a fixed fee, which is initially recorded as deferred revenue andrecognized on a proportional performance basis as the services are performed. We also provide consulting services to help customers optimizethe use of our products. We charge customers for our consulting services on a time-and-materials basis and we recognize that revenue asservices are performed.We typically invoice customers annually in advance for annual and multi-year subscriptions and invoice in advance or on a time-and-materials basis for professional services. We record amounts invoiced for portions of annual subscription periods that have not occurred orservices that have not been performed as deferred revenue on our consolidated balance sheet.We sell our solutions primarily through our direct sales force, which leverages our relationships with technology vendors, professionalservices firms and business process outsourcers. In particular, we have a strategic relationship with SAP. Our solution is an SAP endorsedbusiness solution that integrates with SAP’s ERP solutions. Under our agreement with SAP, which we entered into in 2013, we pay SAP a feebased on a percentage of revenues from our new customers that use an SAP ERP system. We continue to pay SAP a fee for these customersover the term of their subscription45 agreements. For the years ended December 31, 2017, 2016, and 2015, revenues from our customers that use an SAP ERP solution accounted for$33.3 million, or 19%, $20.7 million, or 17%, and $9.4 million, or 11%, respectively, of our total revenues.We target our sales and marketing efforts at both enterprise and mid-market businesses. We define the enterprise market as companieswith greater than $500 million in annual revenue, and we define mid-market as companies with between $50 and $500 million in annual revenue.For the year ended December 31, 2017, sales to enterprise and mid-market customers represented 84% and 16% of our revenues, respectively.For the year ended December 31, 2016, sales to enterprise and mid-market customers represented 85% and 15% of our revenues, respectively.For the year ended December 31, 2015, sales to enterprise and mid-market customers represented 86% and 14% of our revenues,respectively. Additionally, we target our efforts at both new customers and existing customers. Existing customers may renew their subscriptionsand broaden the deployment of our platform across their organizations by increasing the number of users accessing our platform or by addingadditional products.For the year ended December 31, 2017, our dollar-based net revenue retention rate declined primarily due to lower net growth in our existingcustomer accounts as we continue to focus on selling larger initial contract sizes. Our ability to maximize the lifetime value of our customerrelationships will depend, in part, on the willingness of the customer to purchase additional user licenses and products from us. We rely on oursales and customer success teams to support and grow our existing customers by maintaining high customer satisfaction and educating thecustomer on the value all our products provide.The length of our sales cycle depends on the size of the potential customer and contract, as well as the type of solution or product beingpurchased. The sales cycle for our global enterprise customers is generally longer than that of our mid-market customers. In addition, the lengthof the sales cycle tends to increase for larger contracts and for more complex, strategic products like Intercompany Hub. As we continue to focuson increasing our average contract size and selling more strategic products, we expect our sales cycle to lengthen and become less predictable,which could cause variability in our results for any particular period.We have historically signed a higher percentage of agreements with new customers, as well as renewal agreements with existingcustomers, in the fourth quarter of each year and usually during the last month of the quarter. This can be attributed to buying patterns typical inthe software industry. As the terms of most of our customer agreements are measured in full year increments, agreements initially entered into thefourth quarter or last month of any quarter will generally come up for renewal at that same time in subsequent years. This seasonality is reflectedin our revenues, though the impact to overall annual or quarterly revenues is minimal due to the fact that we recognize subscription revenue ratablyover the term of the customer contract.For the years ended December 31, 2017, 2016, and 2015, we had revenues of $177.0 million, $123.1 million and $83.6 million respectively,and we incurred net losses of $38.1 million, $39.2 million, and $24.7 million, respectively.We will adopt ASC 606 in the first quarter of 2018 using the retrospective method, which will result in the retrospective adjustment of ourconsolidated financial statements for the years ended December 31, 2017 and 2016. The adoption of this new standard will impact how we accountfor certain of our revenue arrangements and for sales commissions. See “Significant Accounting Policies - Recent accounting pronouncements” inNote 2 of the accompanying notes to our consolidated financial statements for additional information.On November 2, 2016, we completed our initial public offering and raised net proceeds of approximately $151.9 million and used $67.7million of the proceeds to repay all amounts outstanding under our credit facility.Runbook AcquisitionOn August 31, 2016, we completed our acquisition of Runbook Company B.V., or Runbook, a Netherlands-based provider of financial closeautomation software and integration solutions for SAP customers, or the Runbook Acquisition. We acquired Runbook to enhance the connectivityand integration of our platform to SAP and other systems. We believe this acquisition enhances our position as a leading provider of softwaresolutions to automate the financial close process for SAP customers and supports our European expansion strategy.The aggregate purchase consideration of $34.1 million for the Runbook Acquisition was paid in cash on the acquisition date. The purchaseconsideration is subject to a final working capital adjustment, which has not yet been46 finalized. Any adjustment will be recorded in the consolidated statement of operations in the period of settlement. The estimated purchasedworking capital included approximately $2.6 million in cash. We amended our credit facility to add an additional term loan pursuant to which weborrowed $30.0 million and used the proceeds and cash on hand to fund the acquisition. In connection with our initial public offering, we repaid allamounts outstanding under the term loan. We incurred $1.6 million in transaction costs and fees to complete the Runbook Acquisition.Runbook’s revenues consist of license fees associated with the sale of its on-premise software, post-contract support, and professionalservices required to implement its solutions and train its customers.Factors Affecting PerformanceWe believe that our future performance will depend on many factors, including those described below. While these areas present significantopportunity, they also present risks that we must manage to achieve successful results. See Part I, Item 1A, “Risk Factors.” If we are unable toaddress these challenges, our business and operating results could be adversely affected.Expansion and Further Penetration of Our Customer Base. We employ a “land-and-expand” sales strategy that focuses on efficientlyacquiring new customers and growing our relationships with existing customers over time. We believe significant opportunity exists for us toacquire new customers in both the enterprise and mid-market segments across all geographies, as well as expand the use of our platform byselling additional products and increasing the number of users within our current customers’ organizations.Investment in Growth. We plan to continue to invest in our business so that we can capitalize on our market opportunity. We intend tocontinue to grow our global sales and marketing team to acquire new customers and to increase sales to existing customers. We intend tocontinue to grow our research and development team to extend the functionality and range of our applications to bring new and improved solutionsto accounting and finance. However, we expect our sales and marketing expenses and research and development expenses as a percentage ofrevenues to decrease over time as we grow our revenues and gain economies of scale by increasing our customer base and increase sales to ourexisting customer base. We believe that these investments will contribute to our long-term growth, although they may adversely affect ourprofitability in the near term.Leveraging Strategic Relationships. We plan to continue to strengthen and expand our relationships with technology vendors,professional services firms, business process outsourcers, and resellers. These relationships enable us to increase the speed of deployment andoffer a wider range of integrated services to our customers. We intend to support these existing relationships, seek additional relationships andfurther expand our channel of resellers to help us increase our presence in existing markets and to expand into new markets. Our business andresults of operations will be significantly affected by our success in leveraging and expanding these relationships.Market Adoption of Our Platform. A key focus of our sales and marketing efforts is creating market awareness about the benefits of ourcloud-based SaaS platform. The market for SaaS solutions for accounting and finance is less mature than the market for on-premise accountingand finance software applications, and potential customers may be slow or unwilling to migrate from their legacy solutions such as spreadsheets,manual processes or home grown solutions. It is difficult to predict customer adoption rates and demand, the future growth rate and size of theSaaS platform for accounting and finance market or the entry of competitive solutions. Our business and operating results will be significantlyaffected by the degree to, and speed with, which organizations adopt our solutions.Key MetricsWe regularly review a number of metrics, including the following key metrics, to evaluate our business, measure our performance, identifytrends affecting our business, formulate financial projections, and make strategic decisions. Each of the metrics below exclude the impact of on-premise software. Year Ended December 31, 2017 2016 2015 Dollar-based net revenue retention rate 112% 116% 120%Number of customers (at end of period) 2,208 1,758 1,338 Number of users (at end of period) 196,612 166,903 128,726 47 Dollar-based net revenue retention rate. We believe that dollar-based net revenue retention rate is an important metric to measure thelong-term value of customer agreements and our ability to retain and grow our relationships with existing customers over time. We calculate dollar-based net revenue retention rate as the implied monthly subscription and support revenue at the end of a period for the base set of customers fromwhich we generated subscription revenue in the year prior to the calculation, divided by the implied monthly subscription and support revenue oneyear prior to the date of calculation for that same customer base. This calculation does not reflect implied monthly subscription and supportrevenue for new customers added during the one-year period but does include the effect of customers who terminated during the period. We defineimplied monthly subscription and support revenue as the total amount of minimum subscription and support revenue contractually committed to,under each of our customer agreements over the entire term of the agreement, divided by the number of months in the term of the agreement. Forthe year ended December 31, 2017, our dollar-based net revenue retention rate declined primarily due to lower net growth in our existing customeraccounts as we continue to focus on selling larger initial contract sizes. Our ability to maximize the lifetime value of our customer relationshipswill depend, in part, on the willingness of the customer to purchase additional user licenses and products from us. We rely on our sales andcustomer success teams to support and grow our existing customers by maintaining high customer satisfaction and educating the customer onthe value all our products provide.Number of customers. We believe that our ability to expand our customer base is an indicator of our market penetration and the growth ofour business. We define a customer as an entity with an active subscription agreement as of the measurement date. In situations where anorganization has multiple subsidiaries or divisions, each entity that is invoiced as a separate entity is treated as a separate customer. However,where an existing customer requests its invoice be divided for the sole purpose of restructuring its internal billing arrangement without anyincremental increase in revenue, such customer continues to be treated as a single customer. For the years ended December 31, 2017, 2016, and2015, no single customer accounted for more than 10% of our total revenues.Number of users. Since our customers generally pay fees based on the number of users of our platform within their organization, webelieve the total number of users is an indicator of the growth of our business. We are also beginning to sell an increasing number of non-userbased strategic products.Key Components of our Results of OperationsRevenuesSubscription and support. The majority of subscriptions are sold through one-year non-cancellable contracts and a growing percentageof subscriptions are sold through three-year contracts. Fees are based on a number of factors, including the number of users having access to theproducts and the number of products purchased by the customer. The first year of subscription fees are typically payable within 30 days afterexecution of a contract, and thereafter upon renewal. We initially record the subscription fees as deferred revenue and recognize revenue on astraight-line basis over the term of the agreement. At any time during the subscription period, customers may increase their number of users andadd products. Additional fees are payable for the remainder of the initial or renewed contract term. Customers may only reduce their number ofusers or subscription to products upon renewal of their arrangement. Revenues from subscriptions to our cloud-based software platform comprisedapproximately 95% of our revenues for the year ended December 31, 2017.Subscription and support revenues also include revenues associated with sales of on-premise software licenses and related support. Priorto our migration to SaaS in 2012, we licensed our legacy on-premise software. We no longer develop any new applications or functionality for ourlegacy on-premise software, but we continue to provide post-contract support to one customer that had not migrated to our SaaS solution atDecember 31, 2017.On August 31, 2016, we acquired Runbook. We plan to migrate Runbook’s Smart Close product to a cloud-based platform, but we continueto sell Runbook’s on-premise software to existing Runbook customers and provide post-contract support and implementation services.Revenues recognized from sales of software licenses, support and implementation services related to software arrangements comprised5%, less than 1%, and 1% of total revenues for the years ended December 31, 2017, 2016, and 2015, respectively.Professional services. We offer our customers implementation and consulting services. Although our platform is ready to useimmediately after a new customer has access to it, we typically help customers implement our solutions for a fixed fee and we recognize revenueover the period such services are performed. We also provide consulting and training services to help customers optimize the use of our products.We charge customers for our consulting and training48 services on a time-and-materials basis and we recognize revenue as services are performed. Professional services revenues comprisedapproximately 5% of our revenues for the year ended December 31, 2017.For a description of our revenue accounting policies, see “Management’s Discussion and Analysis of Financial Condition and Results ofOperations—Critical Accounting Policies and Estimates.”Commencing in 2018, we will adopt ASC 606, which will change the timing of when we recognize revenue for certain of our revenuearrangements. See “Significant Accounting Policies - Recent accounting pronouncements” in Note 2 of the accompanying notes to ourconsolidated financial statements for additional information.Cost of RevenuesSubscription and support cost of revenues. Subscription and support cost of revenues primarily consists of amortization of developedtechnology costs resulting from the 2013 Acquisition and the Runbook Acquisition, salaries, benefits and stock-based compensation associatedwith our hosting operations and support personnel, data center costs related to hosting our cloud-based software, and amortization of capitalizedinternal-use software costs. We also allocate a portion of overhead to subscription and support cost of revenues.Professional services costs of revenues. Costs associated with providing professional services primarily consist of salaries, benefitsand stock-based compensation associated with our implementation personnel. These costs are expensed as incurred when the services areperformed. We also allocate a portion of overhead to professional services cost of revenues.Operating ExpensesSales and marketing. Sales and marketing expenses consist primarily of personnel costs of our sales and marketing employees,including salaries, sales commissions and incentives, benefits and stock-based compensation expense, travel and related costs, commissionspaid in connection with our strategic relationships, outside consulting fees, marketing programs, including lead generation, costs of our annualconference, advertising, and trade shows, other event expenses, and allocated overhead costs. Sales and marketing expenses also includeamortization of customer relationship intangible assets. We defer sales and partner commissions and amortize them ratably over the non-cancelable term of the corresponding subscription agreement. In connection with the adoption of the ASC 606, direct costs to acquire a customerwill be recognized over an estimated period of benefit of five years rather than over the non-cancelable contract term under current guidance. Accordingly, as we have elected to adopt ASC 606 using the retrospective method then we expect to record a reduction in annual sales andmarketing expenses for the years ended December 31, 2017 and 2016 when compared to the accounting under the current guidance. Uponadoption of ASC 606, we expect the annual trend in sales and marketing expenses to continue to increase as we expand our direct sales teamsand increase sales through our strategic relationships and resellers.Research and development. Research and development expenses consist primarily of salaries, benefits and stock-based compensationassociated with our engineering, product and quality assurance personnel and allocated overhead costs. Research and development expensesalso include the cost of third-party contractors. Other than internal-use software development costs that qualify for capitalization, research anddevelopment costs are expensed as incurred. We expect research and development costs to increase as we develop new solutions and makeimprovements to our existing platform.General and administrative. General and administrative expenses consist primarily of salaries, benefits and stock-based compensationassociated with our executive, finance, legal, human resources, compliance, and other administrative personnel, accounting, auditing and legalprofessional services fees, recruitment costs, other corporate-related expenses, and allocated overhead costs. General and administrativeexpenses also include amortization of covenant not to compete and tradename intangible assets, as well as acquisition-related costs to businesscombinations and the change in fair value of contingent consideration. We expect that general and administrative expenses will increase as weincur the costs of compliance associated with being a publicly-traded company, including legal, audit and consulting fees.Interest IncomeInterest income primarily consists of earnings on our cash and cash equivalents and our marketable securities.49 Interest ExpenseInterest expense consists primarily of interest expense from borrowings under our credit facility and amortization of debt discounts andissuance costs. We repaid in full all outstanding debt and terminated our credit facility in November 2016. In connection with the termination of ourcredit facility, we expensed the then-unamortized debt discounts and issuance costs.Change in Fair Value of Common Stock Warrant LiabilityWe issued warrants to purchase common stock in connection with our credit facility. The warrants were measured at fair value each period,with changes in fair value recorded in our consolidated statements of operations. The stock warrants were exercised in May 2017 and, accordingly,there will be no further changes in the fair value recorded in our results of operations.Provision for (Benefit from) Income TaxesWe are subject to federal and state income taxes in the United States and taxes in foreign jurisdictions. We use the liability method ofaccounting for income taxes. Under the liability method, deferred taxes are determined based on the temporary differences between the financialstatement and tax bases of assets and liabilities, using tax rates expected to be in effect during the years in which the bases differences areexpected to reverse.We record a valuation allowance against our deferred tax assets to the extent that realization of the deferred tax assets, includingconsideration of our deferred tax liabilities, is not more likely than not. For the year ended December 31, 2017, for both federal and state incometaxes, our deferred assets exceeded our deferred tax liabilities and because of our recent history of operating losses we believe that the realizationof the deferred tax assets is currently not more likely than not. Accordingly, we have recorded a valuation allowance against our federal and statedeferred tax assets. Taxes for international operations are not material for the years ended December 31, 2017, 2016, and 2015.Non-GAAP Financial MeasuresIn addition to our results determined in accordance with GAAP, we believe the non-GAAP measures below are useful to us and ourinvestors in evaluating our business. These non-GAAP financial measures are useful because they provide consistency and comparability with ourpast performance, facilitate period-to-period comparisons of operations and facilitate comparisons with other peer companies, many of which usesimilar non-GAAP financial measures to supplement their GAAP results. Year Ended December 31, 2017 2016 2015 (in thousands, except percentages) GAAP revenues $177,031 $123,123 $83,607 GAAP gross profit $135,545 $92,912 $60,878 GAAP gross margin 76.6% 75.5% 72.8%GAAP net loss $(38,061) $(39,159) $(24,734) Year Ended December 31, 2017 2016 2015 (in thousands, except percentages) Non-GAAP revenues $177,031 $123,839 $83,607 Non-GAAP gross profit $143,541 $100,711 $67,483 Non-GAAP gross margin 81.1% 81.3% 80.7%Non-GAAP net loss $(3,136) $(16,478) $(20,114) Non-GAAP Revenues. Non-GAAP revenues are defined as GAAP revenues adjusted for the impact of purchase accounting resulting fromthe Runbook Acquisition. Upon the completion of the Runbook Acquisition, deferred revenue was recorded at fair value, resulting in a reductionfrom its then carrying value. The reduction associated with the Runbook Acquisition resulted in reduced revenue for the year ended December 31,2016. We believe that presenting50 non-GAAP revenues is useful to investors as it eliminates the impact of the purchase accounting adjustment to revenues to allow for a directcomparison of revenues between periods.Non-GAAP Gross Profit and Non-GAAP Gross Margin. Non-GAAP gross profit is defined as non-GAAP revenues less GAAP cost ofrevenue adjusted for the impact of purchase accounting resulting from the Runbook Acquisition, the amortization of acquired developed technologyresulting from the 2013 Acquisition and the Runbook Acquisition, and stock-based compensation. Non-GAAP gross margin is defined as non-GAAP gross profit divided by non-GAAP revenues. We believe that presenting non-GAAP gross margin is useful to investors as it eliminates theimpact of certain non-cash expenses and allows a direct comparison of gross margin between periods.Non-GAAP Net Loss. Non-GAAP net loss is defined as GAAP net loss adjusted for the impact of the benefit from income taxes that wewere able to recognize as a result of the deferred tax liabilities associated with the intangible assets established upon the 2013 Acquisition and theRunbook Acquisition, the impact of purchase accounting to revenues resulting from the Runbook Acquisition, amortization of acquired intangibleassets resulting from the 2013 Acquisition and the Runbook Acquisition, stock-based compensation, accretion of debt discount pertaining to ourcredit facility, accretion of warrant discount relating to warrants issued in connection with our credit facility, the change in the fair value ofcontingent consideration, the change in fair value of the common stock warrant liability, acquisition-related costs for the Runbook Acquisition, costincurred in relation to our secondary offering and cost incurred relating to our shelf offering. We believe that presenting non-GAAP net loss isuseful to investors as it eliminates the impact of items that have been impacted by the 2013 Acquisition and the Runbook Acquisition, purchaseaccounting and other related costs in order to allow a direct comparison of net loss between current and future periods.51 Reconciliation of Non-GAAP Financial MeasuresThe following table presents a reconciliation of revenues, gross profit, gross margin, and net loss, the most comparable GAAP measures, tonon-GAAP revenues, non-GAAP gross profit, non-GAAP gross margin and non-GAAP net loss: Year Ended December 31, 2017 2016 2015 (in thousands, except percentages) Non-GAAP Revenues Revenues $177,031 $123,123 $83,607 Purchase accounting adjustment to revenues — 716 — Total Non-GAAP revenues $177,031 $123,839 $83,607 Non-GAAP Gross Profit: Gross profit $135,545 $92,912 $60,878 Purchase accounting adjustment to revenues — 716 — Amortization of developed technology 6,847 6,368 6,139 Stock-based compensation 1,149 715 466 Total Non-GAAP gross profit $143,541 $100,711 $67,483 Gross margin 76.6% 75.5% 72.8%Non-GAAP gross margin 81.1% 81.3% 80.7% Non-GAAP Net Loss: Net loss $(38,061) $(39,159) $(24,734)Benefit from income taxes (174) (6,956) (13,934)Purchase accounting adjustment to revenues — 716 — Amortization of intangibles 13,310 12,505 12,092 Stock-based compensation 16,044 6,526 5,497 Accretion of debt discount — 1,303 228 Accretion of warrant discount — 754 276 Change in fair value of contingent consideration 628 371 41 Change in fair value of the common stock warrant liability 3,490 5,880 420 Acquisition-related costs — 1,582 — Secondary offering costs 809 — — Shelf offering costs 818 — — Total Non-GAAP net loss $(3,136) $(16,478) $(20,114) Results of OperationsThe following tables set forth selected historical consolidated statements of operations data, which should be read in conjunction withCritical Accounting Policies and Estimates, Liquidity and Capital Resources, and Contractual Obligations and Commitments included in this Item7, as well as Quantitative and Qualitative Disclosures About Market Risk and the Consolidated Financial Statements and Notes thereto includedelsewhere in this Annual Report on Form 10-K.Consolidated statements of operations information was as follows (in thousands):52 Year Ended December 31, 2017 2016 2015 (in thousands, except per share data) Revenues Subscription and support $168,542 $117,524 $80,080 Professional services 8,489 5,599 3,527 Total revenues 177,031 123,123 83,607 Cost of revenues Subscription and support 33,631 25,900 19,773 Professional services 7,855 4,311 2,956 Total cost of revenues 41,486 30,211 22,729 Gross profit 135,545 92,912 60,878 Operating expenses Sales and marketing 109,775 77,810 56,546 Research and development 23,874 21,125 18,216 General and administrative 36,956 27,911 20,928 Total operating expenses 170,605 126,846 95,690 Loss from operations (35,060) (33,934) (34,812)Other income (expense) Interest income 1,069 4 — Interest expense (13) (5,936) (3,215)Change in fair value of the common stock warrant liability (3,490) (5,880) (420)Other expense, net (2,434) (11,812) (3,635)Loss before income taxes (37,494) (45,746) (38,447)Provision for (benefit from) income taxes 567 (6,587) (13,713)Net loss $(38,061) $(39,159) $(24,734) Year Ended December 31, 2017 compared to Year Ended December 31, 2016Revenues Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Subscription and support $168,542 $117,524 $51,018 43%Professional services 8,489 5,599 2,890 52%Total revenues $177,031 $123,123 $53,908 44% Year Ended December 31, 2017 2016 Dollar-based net revenue retention rate* 112% 116%Number of customers (at end of period)* 2,208 1,758 Number of users (at end of period)* 196,612 166,903 * Exclusive of on-premise software The increase in revenues for the year ended December 31, 2017, compared to the year ended December 31, 2016, was primarily due to anincrease in the number of customers, an increase in the number of users added by existing customers and an increase in the number of productspurchased by existing customers in the period. The total number of customers and users increased by 26% and 18%, respectively, during theyear ended December 31, 2017.53 Cost of revenues Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Subscription and support $33,631 $25,900 $7,731 30%Professional services 7,855 4,311 3,544 82%Total cost of revenues $41,486 $30,211 $11,275 37%Gross margin 76.6% 75.5% The increase in cost of revenues for the year ended December 31, 2017, compared to the year ended December 31, 2016, was primarily dueto a $7.2 million increase in salaries, benefits and stock-based compensation; a $1.0 million increase in amortization of developed technology; a$0.8 million increase in depreciation and amortization; a $0.8 million increase in data center costs; a $0.6 million increase in overhead-relatedexpenses; a $0.5 million increase in computer software expenses; and a $0.3 million increase in travel-related costs. Salaries, benefits and stock-based compensation increased primarily due to growth in headcount, which increased by 13% between December 31, 2016 and 2017. Amortizationof our capitalized software development costs increased due to larger total capitalized costs as we expanded the functionality of oursolutions. Amortization of developed technology increased due to the Runbook Acquisition, which closed on August 31, 2016.Gross margin remained relatively flat during the year ended December 31, 2017, compared to the year ended December 31, 2016.Sales and marketing Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Sales and marketing $109,775 $77,810 $31,965 41%Percentage of total revenues 62.0% 63.2% The increase in sales and marketing expenses for the year ended December 31, 2017, compared to the year ended December 31, 2016,was primarily due to a $13.5 million increase in salaries, sales commissions and incentives; a $8.3 million increase in stock-based compensation;a $4.1 million increase in advertising and trade show expenses; a $3.7 million increase in commissions payable to third-party partners; a $1.1million increase in travel-related costs; a $0.7 million increase in overhead-related expenses; a $0.5 million increase in computer softwareexpenses; and a $0.3 million increase in depreciation and amortization. These increases were partially offset by a $0.3 million decrease inprofessional services expense. The increase in salaries, sales commissions and incentives was primarily driven by an increase in headcount andrevenue growth. Our sales and marketing headcount increased by 32% between December 31, 2016 and 2017. The increase in our stock-basedcompensation was primarily related to modifications made to Australian stock option awards in the quarter ended September 30, 2017. Theincreases in commissions payable to third party-partners was primarily driven by the expansion of our relationships with technology vendors,including SAP. The increase in advertising and trade shows was primarily due to an increase in our marketing efforts. Travel-related costs haveincreased due to the expansion of our sales organization.Research and development Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Research and development $23,874 $21,125 $2,749 13%Percentage of total revenues 13.5% 17.2% The increase in research and development expenses for the year ended December 31, 2017, compared to the year ended December 31,2016, was primarily due to a $3.1 million increase in salaries and benefits; a $0.7 million increase in professional services expense, and a $0.2million increase in travel-related costs, partially offset by a $1.5 million54 decrease in capitalized software costs. Our research and development headcount increased by 9% between December 31, 2016 and 2017.General and administrative Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) General and administrative $36,956 $27,911 $9,045 32%Percentage of total revenues 20.9% 22.7% The increase in general and administrative expenses for the year ended December 31, 2017, compared to the year ended December 31,2016, was primarily due to a $4.2 million increase in professional services expense; a $4.1 million increase in salaries, benefits and stock-basedcompensation; a $0.9 million increase in non-income taxes; a $0.6 million increase in depreciation and amortization; and a $0.5 million increase inbad debt expenses. The increase in professional services expense comprised primarily of legal, accounting and consulting costs associated withbeing a public company and costs associated with the secondary offering that was completed in the quarter ended June 30, 2017 and the shelfoffering that was completed in the quarter ended December 31, 2017. The increase in salaries, benefits and stock-based compensation wasprimarily driven by a 37% increase in our general and administrative headcount between December 31, 2016 and 2017. The increase in bad debtexpenses was primarily related to older receivables for on-premise license receivables. The increases in general and administrative expenses werepartially offset by a $1.6 million increase in foreign currency gains primarily related to foreign-denominated cash and the timing of accountsreceivable settlements between quarters.Interest income Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages)Interest income $1,069 $4 $1,065 * * Not meaningful The increase in interest income for the year ended December 31, 2017, compared to the year ended December 31, 2016, was due tointerest earned from investments in marketable securities. In November 2016, we completed our initial public offering and used a portion of theproceeds to invest in marketable securities.Interest expense Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Interest expense $13 $5,936 $(5,923) (100%) The decrease in interest expense for the year ended December 31, 2017, compared to the year ended December 31, 2016, was due to thetermination of our credit facility and associated repayment of term loans in November 2016.Change in fair value of common stock warrant liability Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Change in fair value of common stock warrantliability $(3,490) $(5,880) $2,390 (41%) 55 We valued our common stock warrants using a binomial lattice model. The primary input into the binomial lattice model was the fairvalue of our common stock. The fair value of our common stock increased by approximately 26% between January 1, 2017 and May 26, 2017, thedate the warrants were exercised, increasing our common stock liability by $3.5 million. The stock warrants were exercised on May 26, 2017 and,accordingly, there will be no further changes in the fair value recorded through earnings.Provision for (benefit) from income taxes Year Ended December 31, Change 2017 2016 $ % (in thousands, except percentages) Provision for (benefit from) income taxes $567 $(6,587) $7,154 (109%) We are subject to federal and state income taxes in the United States and taxes in foreign jurisdictions. Our annual estimated effectivetax rate differed from the U.S. federal statutory rate of 34% primarily as a result of state taxes, foreign taxes, and changes in our valuationallowance for domestic income taxes. For the year ended December 31, 2017, we recorded $0.6 million in income tax expense, compared with a$6.6 million income tax benefit for the year ended December 31, 2016. For the year ended December 31, 2016, deferred tax liabilities arising fromour 2013 Acquisition and our Runbook Acquisition were an available source of income to realize a portion of our deferred tax assets, including ourU.S. losses, resulting in the recognition of an income tax benefit during that period. As of December 31, 2016, our U.S. deferred assets exceededour U.S. deferred tax liabilities and given the uncertainty regarding the realizability of our U.S. deferred tax assets, we recorded a full valuationallowance against all our U.S. federal and state net deferred tax assets. For the year ended December 31, 2017, we continued to maintain a fullvaluation allowance on our U.S. federal and state net deferred tax assets as it was more likely than not that those deferred tax assets will not berealized. The provision for income taxes for the year ended December 31, 2017 primarily related to our international operations.Year Ended December 31, 2016 compared to Year Ended December 31, 2015Revenues Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) Subscription and support $117,524 $80,080 $37,444 47%Professional services 5,599 3,527 2,072 59%Total revenues $123,123 $83,607 $39,516 47% Year Ended December 31, 2016 2015 Dollar-based net revenue retention rate* 116% 120%Number of customers (at end of period)* 1,758 1,338 Number of users (at end of period)* 166,903 128,726 * Exclusive of on-premise software The increase in revenues for the year ended December 31, 2016, compared to the year ended December 31, 2015, was primarily due to anincrease in the number of customers, an increase in the number of users added by existing customers and an increase in the number of productspurchased by existing customers. The total number of customers increased by 31% during the year ended December 31, 2016. The total numberof users increased by 30% during the year ended December 31, 2016.56 Cost of revenues Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) Subscription and support $25,900 $19,773 $6,127 31%Professional services 4,311 2,956 1,355 46%Total cost of revenues $30,211 $22,729 $7,482 33%Gross margin 75.5% 72.8% The increase in cost of revenues for the year ended December 31, 2016, compared to the year ended December 31, 2015, was primarily dueto a $5.6 million increase in salaries, benefits and stock-based compensation and a $0.8 million increase in amortization of capitalized softwarecosts. Salaries, benefits and stock-based compensation increased primarily due to growth in headcount, which increased by 45% betweenDecember 31, 2015 and 2016. Amortization of our capitalized software development costs increased due to larger total capitalized costs as weexpanded the functionality of our solutions.Our gross margin was 75.5% and 72.8% for the years ended December 31, 2016 and 2015, respectively. The improvement in gross marginin 2016 compared to 2015 was primarily the result of amortization of developed technology associated with the 2013 Acquisition and included inour cost of revenues, which is a fixed cost each period. Accordingly, an increase in revenues resulted in an improvement in our grossmargin. The improvement in gross margin was partially offset by the amortization expense of acquired developed technology associated with theRunbook Acquisition in August 2016. Sales and marketing Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) Sales and marketing $77,810 $56,546 $21,264 38%Percentage of total revenues 63.2% 67.6% The increase in sales and marketing expenses for the year ended December 31, 2016, compared to the year ended December 31, 2015,was primarily due to a $12.2 million increase in salaries, sales commissions and incentives and stock-based compensation, a $3.0 millionincrease in commissions expense for third parties that refer customers to us, a $1.1 million increase in travel and related costs, a $1.1 millionincrease in advertising and trade shows, and a $0.7 million increase in outside consulting fees. The increase in salaries, sales commissions andincentives and stock-based compensation was primarily driven by an increase in headcount and revenue growth. Our sales and marketingheadcount increased by 31% between December 31, 2015 and 2016. The increase in commissions payable to third parties was primarily driven byrevenue growth associated with our relationship with SAP as an endorsed business solution. The increase in advertising and trade shows wasprimarily due to an increase in our marketing efforts. The increase in consulting fees was primarily due to an increase in digital marketingservices.Research and development Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) Research and development $21,125 $18,216 $2,909 16%Percentage of total revenues 17.2% 21.8% The increase in research and development expenses for the year ended December 31, 2016, compared to the year ended December 31,2015, was primarily due to a $2.5 million increase in salaries, benefits and stock-based compensation due to an increase in headcount and a $1.2million increase in services provided by third-party contractors. These increases were partially offset by an increase in capitalized costs related tosoftware development of $1.1 million. Our research and development headcount increased by 38% between December 31, 2015 and 2016. Costsof third-party57 contractors increased by 27% between 2015 and 2016. The additional headcount and number of third-party contractors were used to furthermaintain, enhance and develop our platform.General and administrative Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) General and administrative $27,911 $20,928 $6,983 33%Percentage of total revenues 22.7% 25.0% The increase in general and administrative expenses for the year ended December 31, 2016, compared to the year ended December 31,2015, was primarily due to a $3.9 million increase in salaries, benefits and stock-based compensation due to an increase in headcount of 30%between December 31, 2015 and 2016, a $0.9 million increase in computer software expenses, a $0.5 million increase in professional servicescosts due primarily to a $1.6 million increase in legal, accounting and auditing fees related to the Runbook Acquisition largely offset by a reductionof $1.1 million in initial public offering readiness fees and recruitment costs, and a $0.4 million increase in foreign exchange transaction losses dueto the strengthening of the U.S. Dollar. In addition, our general and administrative costs in 2016 increased by $0.3 million relating to the change infair value of contingent consideration. There was no significant change in contingent consideration during 2015.Interest income Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages)Interest income $4 $- $4 * * Not meaningful Interest income for the year ended December 31, 2016, compared to the year ended December 31, 2015, remained relatively flat.Interest expense Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) Interest expense $(5,936) $(3,215) $(2,721) 85% The increase in interest expense during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarilydue to a $1.6 million increase in the accretion and write-off of debt issuance costs associated with borrowings under our credit facility, a $0.7million prepayment penalty for early termination of our credit facility, and a $0.6 million increase in interest expense primarily due to a $30.0 millionterm loan under our credit facility issued to fund the Runbook Acquisition in August 2016.Change in fair value of common stock warrant liability Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages)Change in fair value of common stock warrantliability $(5,880) $(420) $(5,460) * * Not meaningful 58 We valued our common stock warrants using a binomial lattice model. The primary input into the binomial lattice model was the fair value ofour common stock. The fair value of our common stock increased by approximately 84% between December 31, 2015 and December 31, 2016,resulting in a $5.9 million, or 107%, increase in our common stock warrant liability.Benefit from income taxes Year Ended December 31, Change 2016 2015 $ % (in thousands, except percentages) Benefit from income taxes $(6,587) $(13,713) $7,126 (52%)Our effective tax rate was 14.4% in 2016 and 35.7% in 2015. The effective tax rate differs from the U.S. federal statutory rate of 34% in2016 primarily because of our full valuation allowance on our federal and state deferred tax assets, expenses not deductible for income taxpurposes including the change in fair value of common stock warrants, state taxes net of federal benefit, acquisition-related costs, and other taxcredits. We record a valuation allowance against our deferred tax assets to the extent that realization of the deferred tax assets, includingconsideration of our deferred tax liabilities, is not more likely than not. For 2016, our federal and state deferred tax assets exceeded our deferredtax liabilities and given our cumulative losses, we believe that it is not more likely than not that these deferred tax assets will berealized. Accordingly, we recorded a valuation allowance on our net deferred tax assets. In 2015, we recorded a valuation allowance on our Stateof California deferred tax assets as these deferred tax assets exceeded our State of California deferred tax liabilities. Taxes for our internationaloperations were not material in 2016 and 2015.Liquidity and Capital ResourcesAt December 31, 2017, our principal sources of liquidity were $112.6 million of cash and cash equivalents and marketable securities, whichprimarily consist of short-term, investment-grade commercial paper, corporate bonds, U.S. treasury securities, and asset-backed securities. Webelieve our existing cash and cash equivalents, investments in marketable securities and cash from operations will be sufficient to meet ourworking capital needs, capital expenditures and financing obligations for at least the next 12 months. Our future capital requirements will depend on many factors, including our growth rate, the expansion of our direct sales force, strategicrelationships and international operations, the timing and extent of spending to support research and development efforts and the continuingmarket acceptance of our solutions. We may require additional equity or debt financing. Sales of additional equity could result in dilution to ourstockholders. If we raise funds by borrowing from third parties, the terms of those financing arrangements would require us to incur interestexpense and may include negative covenants or other restrictions on our business that could impair our operating flexibility. We can provide noassurance that financing will be available at all or, if available, that we could be able to obtain financing on terms favorable to us. If we are unableto raise additional capital when needed, we would be required to curtail our operating activities and capital expenditures, and our businessoperating results and financial condition would be adversely affected.Historical Cash FlowsThe following table sets forth a summary of our cash flows for the periods indicated: Year Ended December 31, 2017 2016 2015 (in thousands) Net cash provided by (used in) operating activities $6,424 $(4,808) $1,006 Net cash used in investing activities $(7,031) $(119,674) $(12,367)Net cash provided by financing activities $9,593 $131,395 $859Net Cash Provided by (Used In) Operating ActivitiesOur net loss and cash flows from operating activities are significantly influenced by our investments in headcount and infrastructure tosupport anticipated growth. In recent periods, our net loss has generally been significantly greater than our use of cash for operating activities dueto our subscription-based revenue model in which billings occur in59 advance of revenue recognition, as well as the substantial amount of non-cash charges which we incur. Non-cash charges primarily includedepreciation and amortization, stock-based compensation, non-cash interest expense related to accretion and write-off of debt discounts, paid inkind interest, and deferred taxes.For the year ended December 31, 2017, cash provided by operations was $6.4 million resulting from net non-cash expenses of $40.8 millionand net cash flow provided by changes in operating assets and liabilities of $3.7 million, largely offset by our net loss of $38.1 million. The $3.7million of net cash flows provided as a result of changes in our operating assets and liabilities reflected a $25.1 million increase in deferredrevenue as a result of the growth of our customer and user base, which are billed in advance of our revenue recognition; a $2.1 million increase inaccrued expenses and other current liabilities; and a $0.9 million decrease in prepaid expenses and other current liabilities. This change in ouroperating assets and liabilities was partially offset by a $19.9 million increase in accounts receivable due to the growth of our customer and userbase; a $4.0 million increase in deferred sales commissions due to an increase in revenues; a $0.3 million increase in other assets; and a $0.2million decrease in other long-term liabilities.For the year ended December 31, 2016, cash used in operations was $4.8 million, resulting from our net loss of $39.2 million and a $6.4million payment for paid-in-kind interest, largely offset by net cash flows provided through changes in net non-cash expenses of $27.3 million andchanges in our operating assets and liabilities of $13.4 million. The $13.4 million of net cash flows provided as a result of changes in our operatingassets and liabilities reflected a $29.5 million increase in deferred revenue as a result of the growth of our customer and user base, which are billedin advance of our revenue recognition, a $3.9 million increase in accrued expenses primarily associated with increases in employee-relatedaccruals as a result of increases in headcount and bonuses, and a $3.5 million increase in accounts payable associated with the growth of thebusiness. The changes in our operating assets and liabilities were partially offset by a $15.5 million increase in accounts receivable due to thegrowth of our customer and user base, a $3.4 million increase in deferred sales commissions due to an increase in revenue, a $3.1 millionincrease in prepaid expenses and other current assets due primarily to increases in prepaid software subscriptions and insurance recognized toexpense over a period of one year or less, and a $1.2 million decrease in other long-term liabilities due primarily to amortization of leaseholdimprovement allowances and free rent periods associated with the expansion of our corporate headquarters.For the year ended December 31, 2015, cash provided by operations was $1.0 million, resulting from our net loss of $24.7 million, largelyoffset by net cash flows provided through changes in our operating assets and liabilities of $16.4 million and net non-cash expenses of $9.4million. The $16.4 million of net cash flows provided as a result of changes in our operating assets and liabilities reflected a $18.2 million increasein deferred revenue as a result of the growth of our customer and user base, which are billed in advance of our revenue recognition, a $6.8 millionincrease in accrued expenses primarily associated with increases in employee-related accruals as a result of increases in headcount and bonuses,and professional services costs, a $2.0 million increase in other long-term liabilities primarily related to deferred rent due to the leaseholdimprovement allowances and free rent periods associated with the expansion of our corporate headquarters, and a $1.1 million increase inaccounts payable associated with the growth of our business. The changes in our operating assets and liabilities were partially offset by a $6.2million increase in accounts receivable due to the growth of our customer and user base and a $4.3 million increase in deferred sales commissionsdue to an increase in revenues.Net Cash Used In Investing ActivitiesOur investing activities consist primarily of investments in and maturities of marketable securities, capital expenditures for property andequipment and capitalized software development costs.For the year ended December 31, 2017, cash used in investing activities was $7.0 million as a result of $4.6 million in payments of costsrelated to capitalized software development activities and $4.0 million in purchases of property and equipment, partially offset by $1.6 million inproceeds from maturities of marketable securities, net of purchases.For the year ended December 31, 2016, cash used in investing activities was $119.7 million as a result of $83.2 million of investments inmarketable securities, which are primarily comprised of U.S. Treasury and corporate bonds, and the Runbook Acquisition, with a total purchaseprice of $34.1 million, partially offset by cash acquired in the amount of $2.6 million, $3.3 million in capitalized software development costs and$1.7 million of purchases of property and equipment.For the year ended December 31, 2015, cash used in investing activities was $12.4 million as a result of $10.1 million in purchases ofproperty and equipment of which $7.1 million related to the expansion of our global headquarters. During 2015, we also paid $2.3 million of costsrelated to capitalized software development activities.60 Net Cash Provided By Financing ActivitiesFor the year ended December 31, 2017, cash provided by financing activities was $9.6 million primarily as a result of $10.3 million ofproceeds from the exercises of stock options, partially offset by $0.5 million of principal payments on capital lease obligations.For the year ended December 31, 2016, cash provided by financing activities was $131.4 million as a result of the successful completion ofour initial public offering, which resulted in proceeds of $151.9 million, net of underwriting discounts and commissions and other offering expenses,including $4.4 million in cash paid for deferred offering costs; $34.3 million in proceeds under our credit facility, $3.1 million in proceeds from ourissuance of common stock to former employees of Runbook Company B.V.; and $2.9 million in proceeds from exercise of stock options, partiallyoffset by the termination of our credit facility in November 2016 and the associated repayment of term loans and prepayment penalties in theamount of $60.7 million. For the year ended December 31, 2015, cash provided by financing activities was $0.9 million as a result of $1.4 million in proceeds fromexercises of stock options, partially offset by $0.5 million in principal payments on capital lease obligations.BacklogWe enter into both single and multi-year subscription contracts for our solutions. The timing of our invoices to the customer is a negotiatedterm and thus varies among our subscription contracts. For multi-year agreements, it is common to invoice an initial amount at contract signingfollowed by subsequent annual invoices. At any point in the contract term, there can be amounts that we have not yet been contractually able toinvoice. Until such time as these amounts are invoiced, they are not recorded in revenues, deferred revenue or elsewhere in our consolidatedfinancial statements and are considered by us to be backlog. At December 31, 2017 and 2016, we had backlog of approximately $120.4 millionand $78.7 million, respectively. We expect backlog will change from period to period for several reasons, including the timing and duration ofcustomer agreements, varying billing cycles of subscription agreements, and the timing and duration of customer renewals. Because revenue forany period is a function of revenue recognized from deferred revenue under contracts in existence at the beginning of the period, as well ascontract renewals and new customer contracts during the period, backlog at the beginning of any period is not necessarily indicative of futurerevenue performance. We do not utilize backlog as a key management metric internally.Contractual Obligations and CommitmentsThe following table summarizes our contractual obligations at December 31, 2017: Payments Due by Period Total Less than 1 Year 1-3 Years 3-5 Years More than 5 Years Operating lease obligations (1) $21,157 $5,380 $7,672 $5,229 $2,876 Purchase obligations 2,454 1,664 790 — — Capital lease obligations 442 442 — — — $24,053 $7,486 $8,462 $5,229 $2,876 (1)Operating leases include total future minimum rent payments under non-cancelable operating lease agreements.We are required to pay up to a maximum of $8 million of contingent consideration relating to our 2013 Acquisition if we realize a tax benefitfrom the use of net operating losses generated from the stock option exercises concurrent with the 2013 Acquisition. We have not included thisobligation in the table above because there is a high degree of uncertainty regarding the amount and timing of future cash flows to extinguish thisliability. The settlement of this liability depends on our ability to generate taxable income in the future to realize this tax benefit.At December 31, 2017, liabilities for unrecognized tax benefits of $0.7 million are not included in the table above because, due to theirnature, there is a high degree of uncertainty regarding the timing of future cash outflows and other events that extinguish these liabilities.61 Off-Balance Sheet ArrangementsAs part of our ongoing business, we do not have any relationships with other entities or financial partnerships, such as entities often referredto as structured finance or special purpose entities that have been established for the purpose of facilitating off-balance sheet arrangements orother contractually narrow or limited purposes. We are therefore not exposed to any financing, liquidity, market or credit risk that could arise if wehad engaged in those types of relationships.In the ordinary course of business, we may provide indemnification of varying scope and terms to customers, vendors, investors, directorsand officers with respect to certain matters, including, but not limited to, losses arising out of our breach of such agreements, services to beprovided by us, or from intellectual property infringement claims made by third parties. These indemnification provisions may survive termination ofthe underlying agreement and the maximum potential amount of future payments we could be required to make under these indemnificationprovisions may not be subject to maximum loss clauses. The maximum potential amount of future payments we could be required to make underthese indemnification provisions is indeterminable. We have never paid a material claim, nor have we been sued in connection with theseindemnification arrangements. At December 31, 2017, we have not accrued a liability for these indemnification arrangements because thelikelihood of incurring a payment obligation, if any, in connection with these indemnification arrangements is not probable or reasonably estimable.Critical Accounting Policies and EstimatesOur financial statements and the related notes included elsewhere in this Annual Report on Form 10-K are prepared in accordance withgenerally accepted accounting principles, or GAAP, in the United States. The preparation of consolidated financial statements in conformity withGAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure ofcontingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses duringthe reporting period. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience andvarious other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.We believe that the following critical accounting policies involve a greater degree of judgment or complexity than our other accountingpolicies. Accordingly, these are the policies we believe are the most critical to a full understanding and evaluation of our consolidated financialcondition and results of operations. See “Significant Accounting Policies” in Note 2 of the accompanying notes to our consolidated financialstatements for additional information.Revenue Recognition and Deferred RevenueSubscription and support revenue—Customers pay subscription fees for access to our SaaS platform generally for a one-year period. Inmore limited cases, customers may pay for up to three years in advance. Fees are based on a number of factors, including the solutionssubscribed for by the customer and the number of users having access to the solutions. The first year subscription fees are typically payablewithin 30 days after the execution of the arrangement, and thereafter upon renewal. We initially record the subscription fees as deferred revenueand recognize revenue on a straight-line basis over the term of the agreement. At any time during the subscription period, customers may increasethe number of their users or subscribe for additional products. Additional user fees and additional product subscriptions are payable for theremainder of the initial or extended contract term. Subscription and support revenue also includes software revenue related to maintenance andsupport fees on legacy BlackLine solutions and software license and maintenance revenue on Runbook software sales.Professional services—We offer customers assistance in implementing our solutions and optimizing their use. Professional servicesinclude training and consulting. These services are billed on either a fixed fee or time and material basis. Revenues from time and materialarrangements are recognized as services are performed and revenues from fixed fee arrangements are initially recorded as deferred revenue andrecognized on a proportional performance basis as the services are performed.We recognize revenues when: (i) persuasive evidence of an arrangement for the sale of our solutions or implementation and consultingservices exists, (ii) the solutions have been made available or delivered, or services have been performed, (iii) the sales price is fixed ordeterminable, and (iv) collectability is reasonably assured. The timing and amount we recognize as revenue is determined based on the facts andcircumstances of each customer’s arrangement. Evidence of an arrangement consists of a signed customer agreement. We consider that deliveryof a solution has commenced once we provide the customer with log-in information to access and use the solution. Fees are fixed based62 on stated rates specified in the customer agreement. We assess collectability based on a number of factors, including the creditworthiness of thecustomer, review of their financial information or transaction history. If collectability is not considered reasonably assured, revenue is deferred untilthe fees are collected.The majority of customer arrangements include multiple deliverables such as subscriptions to our SaaS solutions and professional services.We recognize revenue in accordance with the guidance for arrangements with multiple deliverables under Accounting Standards Update, or ASU,2009-13 – Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements – a Consensus of the Emerging Issues Task Force orASU 2009-13. For subscription agreements, as customers do not have the right to the software code underlying our solutions, subscriptionrevenue arrangements are outside the scope of software revenue recognition guidance as defined by ASC Topic 985-605, Software. Ouragreements do not contain any refund provisions other than in the event of our non-performance or breach.For multiple-deliverable revenue arrangements, we first assess whether each deliverable has value to the customer on a standalone basis.We have determined that the SaaS solutions have standalone value, because, once access is given to the customer, the solutions are fullyfunctional and do not require any additional development, modification, or customization. Professional services have standalone value, becausethird-party partners and customers themselves can perform these services without our involvement. The performance of these professionalservices generally does not require highly specialized or technologically skilled individuals and the professional services are not essential to thefunctionality of the solutions.We allocate revenue among the separate non-contingent deliverables in an arrangement under the relative selling price method using theselling price hierarchy established in ASU 2009-13. This hierarchy requires the selling price of each deliverable in a multiple deliverablearrangement to be based on, in descending order: (i) vendor-specific objective evidence of fair value, or VSOE, (ii) third-party evidence of fairvalue, or TPE, or (iii) management’s best estimate of the selling price, or BESP. We are not able to determine VSOE or TPE for our deliverables, because the deliverables are typically bundled and infrequently soldseparately within a consistent price range. Additionally, management has determined that there are no third-party offerings reasonably comparableto our solutions. Therefore, the selling prices of subscriptions to the SaaS solutions and professional services are based on BESP. Thedetermination of BESP requires us to make significant estimates and judgments. We consider numerous factors, including the nature of thedeliverables themselves, geography, customer size and number of users, and discounting practices. The determination of BESP is made throughconsultation with senior management. We update our estimates of BESP on an ongoing basis as events and as circumstances may require. Asour marketing strategies evolve, we may modify its pricing practices in the future, which could result in changes in relative selling prices andBESP.In addition to our direct sales and marketing efforts, we have strategic relationships with business process outsourcers, or BPOs, andresellers. The BPOs and resellers place orders with us after receiving an order from an end customer. The BPOs and resellers receive businessterms of sale similar to those received by our direct customers, and payment to us is not contingent on the receipt of payment from the endcustomer. The BPOs and resellers negotiate pricing with the end customer and are responsible for implementation services, if any, and for certainsupport levels directly with the end customer. We recognize revenue over the term of the arrangement for the contractual amount charged to theBPO or reseller, once access to our solution has been provided to the end customer provided that the other revenue recognition criteria notedabove have been met.Deferred Sales CommissionsDeferred sales commissions are the incremental costs that are directly associated with non-cancelable subscription contracts withcustomers and consist of sales commissions paid to our direct sales force and third-party partners. The commissions are deferred and amortizedover the non-cancelable terms of the related customer contracts, which are typically one year in duration. The commission payments are paid infull the month after the customer’s service commences. The deferred commission amounts are recoverable through the future revenue streamsunder the non-cancelable customer contracts. We believe this is the preferable method of accounting as the sales commission charges are soclosely related to the revenue from the non-cancelable customer contracts that they should be recorded as an asset and charged to expense overthe same period that the subscription revenue is recognized. Amortization of deferred sales commissions is included in sales and marketing in ourconsolidated statements of operations.63 Stock-Based CompensationWe account for stock-based compensation awards granted to employees and directors based on the awards’ estimated grant date fair value.We estimate the fair value of our stock options using the Black-Scholes option-pricing model. For awards that vest solely based on continuedservice (“service-only vesting conditions”), the resulting fair value is recognized on a straight-line basis over the period during which an employeeis required to provide service in exchange for the award, usually the vesting period, which is generally four years. We recognize the fair value ofstock options which contain performance conditions based upon the probability of the performance conditions being met, using the graded vestingmethod. Forfeitures are recognized in the period they occur.Determining the grant date fair value of options using the Black-Scholes option pricing model requires management to make assumptionsand judgments. These estimates involve inherent uncertainties and if different assumptions had been used, stock-based compensation expensecould have been materially different from the amounts recorded. The assumptions and estimates are as follows: •Value per share of our common stock. Prior to our initial public offering in October 2016, because there was no public market forour common stock, our management, with the assistance of a third-party valuation specialist, determined the fair value of ourcommon stock at the time of the grant of stock options by considering a number of objective and subjective factors, including ouractual operating and financial performance, market conditions and performance of comparable publicly-traded companies,developments and milestones in our company, the likelihood of achieving a liquidity event and transactions involving our commonstock, among other factors. The fair value of the underlying common stock was determined by our board of directors through the dateof the initial public offering. The fair value of our common stock was determined in accordance with applicable elements of thepractice aid issued by the American Institute of Certified Public Accountants, Valuation of Privately Held Company Equity SecuritiesIssued as Compensation. For awards granted subsequent to our initial public offering, the fair value of our common stock is basedon the closing price of our common stock, as reported on the NASDAQ Global Select Market, on the date of grant. •Expected volatility. We determine the expected volatility based on historical average volatilities of similar publicly tradedcompanies corresponding to the expected term of the awards. •Expected term. We determine the expected term of awards which contain service-only vesting conditions using the simplifiedapproach, in which the expected term of an award is presumed to be the mid-point between the vesting date and the expiration dateof the award. •Risk-free interest rate. The risk-free interest rate is based on the United States Treasury yield curve in effect during the period theoptions were granted corresponding to the expected term of the awards. •Estimated dividend yield. The estimated dividend yield is zero, as we do not currently intend to declare dividends in theforeseeable future.In October 2016, we granted options to purchase shares of common stock to two executive officers that vest upon meeting certainperformance conditions and continued service. The performance conditions include meeting yearly cash flow targets and cumulative annualrecurring revenue targets through 2019. If each yearly cash flow target is met through 2019, but the full cumulative annual recurring target through2019 is not met, the executive officers are still able to vest in the award if an additional cash flow target for 2020 and a cumulative annual recurringrevenue target through 2020 are achieved. The cash flow performance targets for each year are determined concurrently with the annual budgetprocess and because each yearly target has not yet been set, no grant date for the options has been established. At December 31, 2017, wedetermined that the achievement of the performance targets is not probable and accordingly, no stock-based compensation expense has beenrecorded for these awards. To the extent that the awards become probable of vesting prior to the grant date, the amount of compensation cost tobe recognized will be based on the then fair value of the options. The fair value of the options will be remeasured each period until a grant date hasbeen established. Accordingly, stock-based compensation cost, if any, to be recognized will depend on the value of the stock options when allperformance conditions have been set and whether the performance conditions are probable of being achieved. Capitalized Software Costs64 We account for the costs of computer software obtained or developed for internal use in accordance with ASC 350, Intangibles—Goodwilland Other (“ASC 350”). We capitalize certain costs in the development of our SaaS subscription solutions when (i) the preliminary project stage iscompleted, (ii) management has authorized further funding for the completion of the project and (iii) it is probable that the project will be completedand performed as intended. These capitalized costs include personnel and related expenses for employees and costs of third-party contractorswho are directly associated with and who devote time to internal-use software projects and, when material, interest costs incurred during thedevelopment. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose.Costs incurred for significant upgrades and enhancements to our SaaS software solutions are also capitalized. Costs incurred for post-configuration training, maintenance and minor modifications or enhancements are expensed as incurred. Capitalized software development costsare amortized using the straight-line method over an estimated useful life of three years.Business CombinationsThe results of businesses acquired in a business combination are included in our consolidated financial statements from the date of theacquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on theacquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.We perform valuations of assets acquired and liabilities assumed and allocate the purchase price to its respective assets and liabilities.Determining the fair value of assets acquired and liabilities assumed requires our management to use significant judgment and estimates includingthe selection of valuation methodologies, estimates of future revenue, costs and cash flows, discount rates and selection of comparablecompanies. We engage the assistance of valuation specialists in concluding on fair value measurements in connection with determining fair valuesof assets acquired and liabilities assumed in a business combination.The fair value of the deferred revenue at the date of acquisition is determined based on the estimated direct and incremental costs to fulfillthe legal performance obligations associated with the deferred revenue, plus a reasonable profit margin. To the extent that the fair value of deferredrevenue at the acquisition date is less than it’s then carrying value, the revenue in periods subsequent to the acquisition date is reduced until suchtime that the underlying revenue is recognized.Contingent consideration payable in cash arising from business combinations is recorded as a liability and measured at fair value eachperiod. Changes in fair value are recorded in general and administrative expenses in the consolidated statements of operations. Determining thefair value of the contingent consideration each period requires our management to make assumptions and judgments. These estimates involveinherent uncertainties and if different assumptions had been used, the fair value of contingent consideration could have been materially differentfrom the amounts recorded. We are required to pay up to a maximum of $8 million of contingent consideration relating to our 2013 Acquisition if werealize a tax benefit from the use of net operating losses generated from the stock option exercises concurrent with the 2013 Acquisition. Wedetermine the fair value of contingent consideration by discounting estimated future taxable income. The significant inputs used in the fair valuemeasurement of contingent consideration are the timing and amount of taxable income in any given period and determining an appropriate discountrate which considers the risk associated with the forecasted taxable income. Significant changes in the estimated future taxable income and theperiods in which they are generated would significantly impact the fair value of the contingent consideration liability. Income TaxesWe use the liability method of accounting for income taxes. Under the liability method, deferred taxes are determined based on thetemporary differences between the financial statement and tax bases of assets and liabilities, using tax rates expected to be in effect during theyears in which the bases differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of thedeferred tax assets will not be realized.The Tax Act was enacted on December 22, 2017 and introduces significant changes to U.S. income tax law. The Tax Act reduces the U.S.statutory tax rate from 35% to 21% and creates a territorial tax system with a onetime mandatory tax on previously deferred foreign earnings of USsubsidiaries, among other provisions.As a result of a full valuation allowance and not having cumulative earnings and profits in foreign jurisdictions, the Tax Act did not impactour effective rate during the fourth quarter of 2017. Additional guidance may be issued by the U.S. Treasury Department, the IRS or otherstandard-setting bodies, which may result in adjustments to the amounts recorded. 65 Certain consequences of these changes, including whether and how state, local and foreign jurisdictions will react to such changes, have not yetbeen determined.We have assessed our income tax positions and recorded tax benefits for all years subject to examination, based upon our evaluation of thefacts, circumstances and information available at each period-end. For those tax positions where we have determined there is a greater than 50%likelihood that a tax benefit will be sustained, we have recorded the largest amount of tax benefit that may potentially be realized upon ultimatesettlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where we have determinedthere is a less than 50% likelihood that a tax benefit will be sustained, no tax benefit has been recognized in our financial statements.Fair Value of Common Stock WarrantsIn September 2013, in connection with the $25 million term loan agreement, we issued warrants to purchase 499,999 shares of commonstock at an exercise price per share of $5.00.Determining the fair value of the common stock warrants each period required our management to make assumptions and judgments. Theseestimates involved inherent uncertainties and if different assumptions had been used, fair value of the common stock warrants could have beenmaterially different from the amounts recorded. The fair value was determined using a binomial lattice valuation model. The significant inputs usedin the fair value measurement of the common stock warrants were the estimated fair value of our common stock and to a lesser extent theexpected stock volatility, the probability of a change in control and future stock issuances which impacted the term of the warrants. The fair valueof our common stock was based on a number of quantitative and qualitative factors as described in Stock-Based Compensation section above.In May 2017, warrants to purchase 499,999 shares of common stock were net exercised resulting in the issuance of 428,033 shares ofcommon stock and, accordingly, there we be no further changes in the fair value.Recent Accounting PronouncementsSee Note 2, "Significant Accounting Policies—Recently Issued Accounting Standards,” of the Notes to Consolidated Financial Statementsincluded in Part II, Item 8 of this Annual Report on Form 10-K for a description of recent accounting pronouncements, including the expected datesof adoption and estimated effects on our financial condition, results of operations and cash flows.Item 7A.Quantitative and Qualitative Disclosures About Market RisksWe have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of ourbusiness. These risks primarily include interest rate, foreign exchange and inflation risks, as well as risks relating to changes in the generaleconomic conditions in the countries where we conduct business. To reduce these risks, we monitor the financial condition of our clients and limitcredit exposure by collecting in advance and setting credit limits as we deem appropriate. In addition, our investment strategy has historically beento invest in financial instruments that are highly liquid and readily convertible into cash and that mature within three months from the date ofpurchase. To date, we have not used derivative instruments to mitigate the impact of our market risk exposures. We have also not used, nor dowe intend to use, derivatives for trading or speculative purposes.Interest Rate RiskWe are exposed to market risk related to changes in interest rates.We had cash and cash equivalents and marketable securities of $112.6 million at December 31, 2017. Our cash equivalents andmarketable securities consist of highly liquid, investment-grade commercial paper, corporate bonds, U.S. treasury bonds, and asset-backedsecurities. The carrying amount of our cash equivalents and marketable securities reasonably approximates fair value due to the highly liquidnature of these instruments. The primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs andthe fiduciary control of cash and investments. We do not enter into investments for trading or speculative purposes. Our investments are exposedto market risk due to fluctuations in interest rates, which may affect our interest income and the fair market value of our investments. Due to theshort-term nature of our investment portfolio, however, we do not believe an immediate 10% increase or decrease in interest rates would have amaterial effect on the fair market value of our portfolio. We therefore do not expect our operating results or cash flows to be materially affected bya sudden change in market interest rates.66 We do not believe our cash equivalents and marketable securities have significant risk of default or illiquidity. While we believe our cashequivalents and marketable securities do not contain excessive risk, we cannot provide absolute assurance that in the future our investments willnot be subject to adverse changes in market value. In addition, we maintain significant amounts of cash and cash equivalents at one or morefinancial institutions that are in excess of federally insured limits. We cannot be assured that we will not experience losses on these deposits.Foreign Currency RiskWe have foreign currency risks related to our revenue and operating expenses denominated in currencies other than the U.S. Dollar. Ourhistorical revenues have primarily been denominated in U.S. Dollars, and a significant portion of our current revenues continue to be denominatedin U.S. Dollars. However, we expect an increasing portion of our future revenues to be denominated in currencies other than the U.S. Dollar,primarily the Euro and British pound. The effect of an immediate 10% adverse change in foreign exchange rates on foreign-denominated accountsreceivable at December 31, 2017 would not be material to our financial condition or results of operations. Our operating expenses are generallydenominated in the currencies of the countries in which our operations are located, primarily the United States and, to a much lesser extent, theUnited Kingdom, other European Union countries, Canada, Australia, and Singapore. Increases and decreases in our foreign-denominated revenuefrom movements in foreign exchange rates are partially offset by the corresponding decreases or increases in our foreign-denominated operatingexpenses.As our international operations grow, our risks associated with fluctuation in currency rates will become greater, and we will continue toreassess our approach to managing this risk. In addition, currency fluctuations or a weakening U.S. Dollar can increase the costs of ourinternational expansion. To date, we have not entered into any foreign currency hedging contracts, since exchange rate fluctuations have not had amaterial impact on our operating results and cash flows. Based on our current international structure, we do not plan on engaging in hedgingactivities in the near future.Inflation RiskWe do not believe that inflation has had a material effect on our business, financial condition or results of operations. Nonetheless, if ourcosts were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases.Our inability or failure to do so could harm our business, financial condition and results of operations. 67 Item 8.Financial Statements and Supplementary DataINDEX TO CONSOLIDATED FINANCIAL STATEMENTS PAGEReport of Independent Registered Public Accounting Firm69Consolidated Balance Sheets at December 31, 2017 and 201670Consolidated Statements of Operations for the years ended December 31, 2017, 2016, and 201571Consolidated Statements of Comprehensive Loss for the years ended December 31, 2017, 2016, and 201572Consolidated Statements of Stockholders’ Equity for the years ended December 31, 2017, 2016, and 201573Consolidated Statements of Cash Flows for the years ended December 31, 2017, 2016, and 201574Notes to Consolidated Financial Statements76 68 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Board of Directors and Stockholders of BlackLine, Inc.

solutions delivered primarily asSoftware as a Service (“SaaS”). The Company’s solutions enable its customers to address various aspects of their financial close processincluding account reconciliations, variance analysis of account balances, journal entry capabilities, and certain types of data matching capabilities.The Company is a holding company and conducts its operations through its wholly-owned subsidiary, BlackLine Systems, Inc. (“BlackLineSystems”). BlackLine Systems funded its business with investments from its founder and cash flows from operations until September 3, 2013,when the Company acquired BlackLine Systems, and Silver Lake Sumeru and Iconiq acquired a controlling interest in the Company, which isreferred to as the “2013 Acquisition.”On August 31, 2016 the Company acquired Runbook Company B.V. (“Runbook”), which is referred to as the “Runbook Acquisition.”The Company is headquartered in Los Angeles, California and has offices in Chicago, Atlanta, New York, Vancouver, London, Paris,Frankfurt, Sydney, Melbourne, Kuala Lumpur, Netherlands, Poland, Romania, Singapore, and South Africa.Note 2—Significant Accounting PoliciesPrinciples of consolidation and basis of presentationThe Company’s consolidated financial statements are presented in accordance with accounting principles generally accepted in the UnitedStates of America (“GAAP”) and include the operating results of its wholly-owned subsidiaries. All intercompany accounts and transactions havebeen eliminated in consolidation.Reverse stock splitOn October 12, 2016, the Company effected a 1-for-5 reverse stock split of its outstanding common stock. All share and per shareamounts for all periods presented in these consolidated financial statements and notes thereto have been adjusted retrospectively, whereapplicable, to reflect this reverse stock split.Use of estimatesThe preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptionsthat affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidatedfinancial statements, and the reported amounts of revenues and expenses during the reporting period.On an ongoing basis, management evaluates its estimates, primarily those related to determining the best estimate of selling price (“BESP”)for separate deliverables in the Company’s subscription revenue arrangements, vendor-specific objective evidence (“VSOE”) for separatedeliverables in the Company’s licensed revenue arrangements, allowance for doubtful accounts, fair value of assets and liabilities assumed in abusiness combination, recoverability of goodwill and long-lived assets, useful lives associated with long-lived assets, income taxes,contingencies, fair value of contingent consideration, and the valuation and assumptions underlying stock-based compensation and common stockwarrants. These estimates are based on historical data and experience, as well as various other factors that management believes to bereasonable under the circumstances. Actual results could differ from those estimates.SegmentsManagement has determined that the Company has one operating segment. The Company’s chief executive officer, who is the Company’schief operating decision maker, reviews financial information on a consolidated and aggregate basis, together with certain operating metricsprincipally to make decisions about how to allocate resources and to measure the Company’s performance.76 Cash and cash equivalentsThe Company considers all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase tobe cash equivalents. Cash includes cash held in checking and savings accounts. Cash equivalents are comprised of investments in moneymarket mutual funds. The carrying value of cash and cash equivalents approximates fair value.Restricted cashIncluded in prepaid expenses and other current assets at December 31, 2017 and other assets at December 31, 2016 was cash totaling$0.4 million, which was required to be restricted as to use by the Company’s office leaseholder to collateralize a standby letter of credit.Investments in Marketable SecuritiesThe Company’s marketable securities consist of commercial paper, corporate bonds, U.S. treasury securities, and asset-backedsecurities. The Company classifies its marketable securities as available-for-sale at the time of purchase, and the Company reevaluates suchclassification as of each balance sheet date. All marketable securities are recorded at their estimated fair value, with any unrealized gains andlosses reported as a component of stockholders’ equity until realized or until a determination is made that an other-than-temporary decline inmarket value has occurred. Impairments are considered to be other than temporary if they are related to deterioration in credit risk or if it is likelythe Company will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value deemed to be otherthan temporary are determined based on the specific identification method and are reported in other income (expense), net in the consolidatedstatements of operations. The Company classifies its investments in marketable securities in current assets as the investments are available for use, if needed, incurrent operations. Investments in marketable securities presented within current assets on the consolidated balance sheet consisted of the following: December 31, 2017 AmortizedCost GrossUnrealizedGains GrossUnrealizedLosses Fair Value (in thousands) Marketable securities U.S. treasury securities $21,454 $— $(19) $21,435 Corporate bonds 32,437 — (43) 32,394 Commercial paper 25,048 — — 25,048 Asset-backed securities 2,600 — (1) 2,599 $81,539 $— $(63) $81,476 December 31, 2016 AmortizedCost GrossUnrealizedGains GrossUnrealizedLosses Fair Value (in thousands) Marketable securities U.S. treasury securities $29,742 $— $(17) $29,725 Corporate bonds 25,522 — (21) 25,501 Commercial paper 15,554 — — 15,554 Asset-backed securities 12,353 — (3) 12,350 $83,171 $— $(41) $83,130 77 During the years ended December 31, 2017 and 2016, there were no sales of marketable securities and, accordingly, there were no realizedgains or losses recognized in the Company’s consolidated statements of operations. Net gains and losses related to maturities of marketablesecurities that were reclassified from accumulated other comprehensive loss to earnings in the consolidated statements of operations were notmaterial for the years ended December 31, 2017 and 2016.The Company’s marketable securities have a contractual maturity of less than 2 years. The amortized cost and fair values of marketablesecurities, by remaining contractual maturity, were as follows: December 31, 2017 AmortizedCost Fair Value (in thousands) Maturing within 1 year $75,339 $75,288 Maturing between 1 year and 2 years 6,200 6,188 $81,539 $81,476 Accounts receivable and allowance for doubtful accountsAccounts receivable are recorded at the invoiced amount, do not require collateral and do not bear interest. The Company estimates itsallowance for doubtful accounts by evaluating specific accounts where information indicates the Company’s customers may have an inability tomeet financial obligations, such as bankruptcy and significantly aged receivables outstanding. Concentration of credit risk and significant customersFinancial instruments that potentially subject the Company to a significant concentration of credit risk consist of cash and cash equivalents,investments in marketable securities and accounts receivable.The Company maintains the majority of its cash balances with one major commercial bank in non-interest bearing accounts, which exceedsthe Federal Deposit Insurance Corporation, or FDIC, federally insured limits.The Company invests its excess cash in money market mutual funds, commercial paper, corporate bonds, U.S. treasury securities, andasset-backed securities. To date, the Company has not experienced any impairment losses on its investments.For the years ended December 31, 2017, 2016, and 2015, no single customer comprised 10% or more of the Company’s total revenues. Nosingle customer had an accounts receivable balance of 10% or greater of total accounts receivable at December 31, 2017 or 2016.Property and equipmentProperty and equipment is stated at cost less accumulated depreciation. Expenditures for repairs and maintenance are expensed asincurred, while renewals and betterments are capitalized. Depreciation expense is charged to operations on a straight-line basis over the estimateduseful lives of the assets.The estimated useful lives of the Company’s property and equipment are as follows: Useful LivesMachinery and equipment 3 to 5 yearsPurchased software 3 to 5 yearsFurniture and fixtures 5 yearsLeasehold improvements Lesser of 7 years or leaseterm Assets acquired under capital leases are capitalized at the present value of the related lease payments and are amortized over the shorterof the lease term or useful life of the asset.78 Capitalized internal-use software costsThe Company accounts for the costs of computer software obtained or developed for internal use in accordance with ASC 350, Intangibles—Goodwill and Other (“ASC 350”). The Company capitalizes certain costs in the development of its Software as a Service (“SaaS”) subscriptionsolution when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project and(iii) it is probable that the project will be completed and performed as intended. These capitalized costs include personnel and related expenses foremployees and costs of third-party contractors who are directly associated with and who devote time to internal-use software projects and, whenmaterial, interest costs incurred during the development. Capitalization of these costs ceases once the project is substantially complete and thesoftware is ready for its intended purpose. Costs incurred for significant upgrades and enhancements to the Company’s SaaS software solutionsare also capitalized. Costs incurred for training, maintenance and minor modifications or enhancements are expensed as incurred. Capitalizedsoftware development costs are amortized using the straight-line method over an estimated useful life of three years.During the years ended December 31, 2017, 2016, and 2015, the Company amortized $2.7 million, $1.8 million, and $0.9 million,respectively, of internal-use software development costs to subscription and support cost of revenue. At December 31, 2017 and 2016, theaccumulated amortization of capitalized internal-use software development costs was $5.6 million and $2.9 million, respectively. Business combinationsThe results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from thedate of the acquisition. Purchase accounting results in assets and liabilities of an acquired business generally being recorded at their estimatedfair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized asgoodwill.Transaction costs associated with business combinations are expensed as incurred and are included in general and administrativeexpenses in the consolidated statements of operations.The Company performs valuations of assets acquired and liabilities assumed and allocates the purchase price to its respective assets andliabilities. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates,including the selection of valuation methodologies, estimates of future revenue, costs and cash flows, discount rates, and selection of comparablecompanies. The Company engages the assistance of valuation specialists in concluding on fair value measurements in connection withdetermining fair values of assets acquired and liabilities assumed in a business combination.Intangible assetsIntangible assets primarily consist of acquired developed technology, customer relationships, trade names and non-compete agreements,which were acquired as part of the 2013 Acquisition and the Runbook Acquisition. The Company determines the appropriate useful life of itsintangible assets by performing an analysis of expected cash flows of the acquired assets. Intangible assets are amortized over their estimateduseful lives using the straight-line method, which approximates the pattern in which the economic benefits are consumed. The estimated usefullives of the Company’s finite-lived intangible assets are as follows: Useful LivesTrade name 1 to 10 yearsDeveloped technology 6 to 8 yearsNon-compete agreements 2 to 5 yearsCustomer relationships 8 to 10 years Impairment of long-lived assetsManagement evaluates the recoverability of the Company’s property and equipment, finite-lived intangible assets and capitalized internal-software costs when events or changes in circumstances indicate a potential impairment exists. Events and changes in circumstances consideredby the Company in determining whether the carrying value of long-lived assets may not be recoverable include, but are not limited to, significantchanges in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry oreconomic trends, and changes in the Company’s business strategy. Impairment testing is performed at an asset level that represents the lowest79 level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (an “asset group”). In determining ifimpairment exists, the Company estimates the undiscounted cash flows to be generated from the use and ultimate disposition of the asset group.If impairment is indicated based on a comparison of the assets’ carrying values and the undiscounted cash flows, the impairment loss ismeasured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company determined that therewere no events or changes in circumstances that potentially indicated that the Company’s long-lived assets were impaired during the years endedDecember 31, 2017, 2016, and 2015.GoodwillGoodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination. The Companytests goodwill for impairment in accordance with the provisions of Accounting Standards Codification (“ASC”) 350, Intangibles—Goodwill andOther. Goodwill is tested for impairment at least annually at the reporting unit level or whenever events or changes in circumstances indicate thatgoodwill might be impaired. Events or changes in circumstances which could trigger an impairment review include a significant adverse change inlegal factors or in the business climate, unanticipated competition, loss of key personnel, significant changes in the use of the acquired assets orthe Company’s strategy, significant negative industry or economic trends, or significant underperformance relative to expected historical orprojected future results of operations.ASC 350 provides that an entity has the option to first assess qualitative factors to determine whether the existence of events orcircumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, afterassessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is lessthan its carrying amount, then additional impairment testing is not required. However, if an entity concludes otherwise, then it is required to performthe first of a two-step impairment test.The first step involves comparing the estimated fair value of a reporting unit with its book value, including goodwill. If the estimated fairvalue exceeds book value, goodwill is considered not to be impaired and no additional steps are necessary. If, however, the fair value of thereporting unit is less than book value, then, under the second step, the carrying amount of the goodwill is compared with its implied fair value. Theestimate of implied fair value of goodwill may require valuations of certain internally-generated and unrecognized intangible assets. If the carryingamount of goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess.The Company has one reporting unit and it tests its goodwill for impairment annually, during the fourth quarter of the calendar year. For 2017and 2016, the Company used the quantitative approach to perform its annual goodwill impairment test. The Company’s fair value significantlyexceeded the carrying value of its net assets and, accordingly, goodwill was not impaired.Deferred rentRent expense is recorded on a straight-line basis over the term of the lease. The difference between rent expense and the cash paid underthe lease agreement is recorded as deferred rent. Lease incentives, including tenant improvement allowances, are also recorded as deferred rentand amortized on a straight-line basis over the lease term.Debt issued with warrants to purchase common stockThe Company issued warrants to purchase common stock in connection with its former credit facility. These warrants were a liabilityclassified under ASC 815-40, Contracts in Entity’s Own Equity, as they contained down-round protection such that, in the event of subsequentissuances of shares at-market by the Company below the exercise price of the warrant, then the warrant’s exercise price was reduced. Thewarrants were measured at fair value each period with changes in fair value recorded in other income (expense), net in the consolidatedstatements of operations. In May 2017, warrants to purchase 499,999 shares of common stock were net exercised resulting in the issuance of428,033 shares of common stock and, accordingly, there will be no further changes in the fair value.The initial carrying value of the debt was reduced by the fair value of the warrants. The resulting debt discount was amortized to interestexpense over the life of the debt on a straight-line basis, which approximated the effective interest method. In November 2016, the Companyrepaid all outstanding debt and expensed the then-remaining unamortized debt discount to interest expense in the consolidated statements ofoperations.80 Fair value of financial instrumentsASC 820, Fair Value Measurements requires entities to disclose the fair value of financial instruments, both assets and liabilities recognizedand not recognized on the balance sheet, for which it is practicable to estimate fair value. Fair value is defined as the exchange price that wouldbe received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in anorderly transaction between market participants on the measurement date.Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the lastunobservable, that may be used to measure fair value, which are the following: Level 1:Quoted prices in active markets for identical or similar assets and liabilities. Level 2:Quoted prices for identical or similar assets and liabilities in markets that are not active or observable inputs other than quotedprices in active markets for identical or similar assets or liabilities. Level 3:Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets orliabilities.At December 31, 2017 and 2016, the carrying values of cash equivalents, accounts receivable, accounts payable, and accrued expenses,approximate fair values due to the short-term nature of such instruments. The following table summarizes the Company’s financial assets and liabilities measured at fair value on a recurring basis at December 31,2017 and 2016, by level, within the fair value hierarchy. Financial assets and financial liabilities are classified in their entirety based on the lowestlevel of input that is significant to the fair value measurement (in thousands): December 31, 2017 Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $21,247 $— $— $21,247 Marketable securities U.S. treasury securities 21,435 — — 21,435 Corporate bonds — 32,394 — 32,394 Commercial paper — 25,048 — 25,048 Asset-backed securities — 2,599 — 2,599 Total assets $42,682 $60,041 $— $102,723 Liabilities Contingent consideration — — 5,866 5,866 Total liabilities $— $— $5,866 $5,866 December 31, 2016 Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $18,936 $— $— $18,936 Marketable securities U.S. treasury securities 29,725 — — 29,725 Corporate bonds — 25,501 — 25,501 Commercial paper — 15,554 — 15,554 Asset-backed securities — 12,349 — 12,349 Total assets $48,661 $53,404 $— $102,065 Liabilities Common stock warrant liability $— $— $11,380 $11,380 Contingent consideration — — 5,238 5,238 Total liabilities $— $— $16,618 $16,618 81 Contingent consideration relating to the 2013 Acquisition (refer to Note 10) is recorded as a liability and is measured at fair value eachperiod, based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. Thevaluation of contingent consideration uses assumptions management believes would be made by a market participant. Management assessesthese estimates on an ongoing basis as additional data impacting the assumptions becomes available. Changes in the fair value of contingentconsideration related to updated assumptions and estimates are recognized within general and administrative expenses in the consolidatedstatements of operations. The Company determined the fair value of the contingent consideration by discounting estimated future taxable income.The significant inputs used in the fair value measurement of contingent consideration are the timing and amount of taxable income in any givenperiod and determining an appropriate discount rate, which considers the risk associated with the forecasted taxable income. Significant changesin the estimated future taxable income and the periods in which they are generated would significantly impact the fair value of the contingentconsideration liability.Warrants to purchase common stock were liability classified and were measured at fair value each period. The fair value was determinedusing a binomial lattice valuation model. The fair value included significant inputs not observable in the market, which represented a Level 3measurement within the fair value hierarchy. The valuation of common stock warrants used assumptions management believed would be made bya market participant. Management assessed these estimates on an ongoing basis as additional data impacting the assumptions became available.Changes in the fair value of the common stock warrant liability related to updated assumptions and estimates were recognized within other income(expense), net in the consolidated statements of operations. The significant inputs used in the fair value measurement of the common stockwarrants were the estimated fair value of the Company’s common stock and, to a lesser extent, the expected stock volatility, the probability of achange in control and future stock issuances, which impacted the term of the warrants.The following table summarizes the changes in the common stock warrant liability (in thousands): Year Ended December 31, 2017 2016 2015 Beginning fair value $11,380 $5,500 $5,080 Change in fair value 3,490 5,880 420 Exercise of stock warrants (14,870) — — Ending fair value $— $11,380 $5,500 In May 2017, warrants to purchase 499,999 shares of common stock were net exercised resulting in the issuance of 428,033 shares ofcommon stock and, accordingly, there will be no further changes in the fair value.The following table summarizes the changes in the contingent consideration liability (in thousands): Year Ended December 31, 2017 2016 2015 Beginning fair value $5,238 $4,867 $4,826 Change in fair value 628 371 41 Ending fair value $5,866 $5,238 $4,867 Certain assets, including goodwill and long-lived assets, are also subject to measurement at fair value on a non-recurring basis if they aredeemed to be impaired a result of an impairment review. For the years ended December 31, 2017, 2016, and 2015, no impairments were identifiedon those assets required to be measured at fair value on a non-recurring basis.Revenue recognitionThe Company derives its revenue from the following sources:Subscription and support revenue – Customers pay subscription fees for access to the Company’s SaaS platform generally for a one-year period. In more limited cases, customers may pay for up to three years in advance. Fees are based on a number of factors, including thesolutions subscribed for by the customer and the number of users having access to the solutions. The first year subscription fees are typicallypayable within 30 days after the execution of the82 arrangement, and thereafter upon renewal. The Company initially records the subscription fees as deferred revenue and recognizes revenue on astraight-line basis over the term of the agreement. At any time during the subscription period, customers may increase the number of their users orsubscribe for additional products. Additional user fees and additional product subscriptions are payable for the remainder of the initial or extendedcontract term. Subscription and support revenue also includes software revenue related to maintenance and support fees on legacy BlackLinesolutions and software license and maintenance revenue on Runbook software sales as described below.Professional services – The Company offers its customers assistance in implementing its SaaS solutions and optimizing their use.Professional services include consulting and training. These services are billed on either a fixed fee or time-and-material basis. Revenues fromtime-and-material arrangements are recognized as services are performed and revenues from fixed fee arrangements are initially recorded asdeferred revenue and recognized on a proportional performance basis as the services are performed.The Company recognizes subscription and professional services revenues when (i) persuasive evidence of an arrangement for the sale ofthe Company’s solutions or consulting services exists, (ii) the solutions have been made available or delivered, or services have been performed,(iii) the sales price is fixed or determinable, and (iv) collectability is reasonably assured. The timing and amount the Company recognizes asrevenue is determined based on the facts and circumstances of each customer’s arrangement. Evidence of an arrangement consists of a signedcustomer agreement. The Company considers that delivery of a solution has commenced once it provides the customer with log-in information toaccess and use the solution. Fees are fixed based on stated rates specified in the customer agreement. The Company assesses collectabilitybased on a number of factors, including the creditworthiness of the customer, review of their financial information or transaction history. Ifcollectability is not considered reasonably assured, revenue is deferred until the fees are collected.The majority of customer arrangements include multiple deliverables, such as subscriptions to the Company’s SaaS solutions andprofessional services. The Company recognizes revenue in accordance with the guidance for arrangements with multiple deliverables underAccounting Standards Update (“ASU”) 2009-13, Revenue Recognition (Topic 605) – Multiple-Deliverable Revenue Arrangements – a Consensus ofthe Emerging Issues Task Force. For subscription agreements, as customers do not have the right to the software code underlying the Company’ssolutions, subscription revenue arrangements are outside the scope of software revenue recognition guidance as defined by ASC 985-605,Software. The Company’s agreements do not contain any refund provisions other than in the event of the Company’s non-performance or breach.For multiple-deliverable revenue arrangements, the Company first assesses whether each deliverable has value to the customer on astandalone basis. The Company has determined that the SaaS products have standalone value because, once access is given to the customer,the solutions are fully functional and do not require any additional development, modification or customization. Professional services havestandalone value because third-party partners and customers themselves can perform these services without the Company’s involvement. Theperformance of these professional services generally does not require highly specialized or technologically skilled individuals and the professionalservices are not essential to the functionality of the solutions.The Company allocates revenue among the separate non-contingent deliverables in an arrangement under the relative selling price methodusing the selling price hierarchy established in ASU 2009-13. This hierarchy requires the selling price of each deliverable in a multiple deliverablearrangement to be based on, in descending order, (i) VSOE, (ii) third-party evidence of fair value (“TPE”) or (iii) BESP.The Company is not able to determine VSOE or TPE for its deliverables because the deliverables are typically bundled and infrequently soldseparately within a consistent price range. Additionally, management has determined that there are no third-party offerings reasonably comparableto the Company’s solutions. Therefore, the selling prices of subscriptions to the SaaS solutions and professional services are based on BESP.The determination of BESP requires the Company to make significant estimates and judgments. The Company considers numerous factors,including the nature of the deliverables themselves, geography, customer size and number of users, and discounting practices. The determinationof BESP is made through consultation with senior management. The Company updates its estimates of BESP on an ongoing basis as events andcircumstances may require. As the Company’s marketing strategies evolve, the Company may modify its pricing practices in the future, whichcould result in changes in relative selling prices and BESP.The Company uses business process outsourcers (“BPOs”) and resellers to complement its direct sales and marketing efforts. The BPOsand resellers place orders with the Company after receiving an order from an end customer. The BPOs and resellers receive business terms ofsale similar to those received by the Company’s direct customers, and83 payment to the Company is not contingent on the receipt of payment from the end customer. The BPOs and resellers negotiate pricing with theend customer and are responsible for implementation services, if any, and for certain support levels directly with the end customer. The Companyrecognizes revenue over the term of the arrangement for the contractual amount charged to the BPO or reseller once access to the Company’ssolution has been provided to the end customer provided that the other revenue recognition criteria noted above have been met.Subscription and support revenues also include revenues associated with sales of software licenses and related support. Prior to thedevelopment of the Company’s SaaS solutions, the Company sold software licenses and post contract support related to its legacy software inaccordance with ASC 985-605. The Company continues to provide post contract support for this legacy software to a limited number of customersthat have not yet migrated to the SaaS solution. The Company no longer develops any new applications or functionality for the legacy softwarelicensed to customers.On August 31, 2016, the Company acquired Runbook, a Netherlands-based provider of licensed financial close automation software andintegration for SAP customers. The Company plans to migrate Runbook’s Smart Close licensed products to a cloud-based platform, but theCompany continues to sell Runbook’s on-premise software to existing Runbook customers and provide post-contract support and implementationservices. Revenues recognized from sales of software licenses, support and implementation services related to software arrangements comprisedapproximately 5%, less than 1%, and 1% of total revenues for the years ended December 31, 2017, 2016, and 2015, respectively.Taxes collected from customers are accounted for on a net basis and are excluded from revenue.Cost of revenuesCost of revenues primarily consists of costs related to hosting the Company’s cloud-based application suite, salaries and benefits ofoperations and support personnel, including stock-based compensation, and amortization of capitalized internal-use software costs. The Companyallocates a portion of overhead, such as rent, information technology costs and depreciation and amortization to cost of revenues. Costsassociated with providing professional services are expensed as incurred when the services are performed. In addition, subscription and supportcost of revenues includes amortization of acquired developed technology.Sales and marketingSales and marketing expenses consist primarily of compensation and employee benefits, including stock-based compensation, of sales andmarketing personnel and related sales support teams, sales and partner commissions, marketing events, advertising costs, travel, trade shows,other marketing materials, and allocated overhead. Sales and marketing expenses also include amortization of customer relationship intangibleassets. Advertising costs are expensed as incurred and totaled $7.7 million, $4.2 million, and $3.0 million for the years ended December 31, 2017,2016, and 2015, respectively.Deferred sales commissionsDeferred sales commissions are the incremental costs that are directly associated with non-cancelable subscription contracts withcustomers and consist of sales commissions paid to the Company’s direct sales force and third-party partners. The commissions are deferred andamortized over the non-cancelable terms of the related customer contracts, which are typically one year in duration. The commission paymentsare paid in full the month after the customer’s service commences. The deferred commission amounts are recoverable through the future revenuestreams under the non-cancelable customer contracts. The Company believes this is the preferable method of accounting as the salescommission charges are so closely related to the revenue from the non-cancelable customer contracts and accordingly, should be recorded as anasset and charged to expense over the same period that the subscription revenue is recognized. Amortization of deferred sales commissions isincluded in sales and marketing in the accompanying consolidated statements of operations. At December 31, 2017 and 2016, deferredcommission costs, net of accumulated amortization were $13.6 million and $9.7 million, respectively. Amortization of commission costs was $18.4million, $13.2 million, and $7.3 million for the years ended December 31, 2017, 2016, and 2015, respectively.84 Research and developmentResearch and development expenses are comprised primarily of salaries, benefits and stock-based compensation associated with theCompany’s engineering, product and quality assurance personnel. Research and development expenses also include third-party contractors andsupplies and allocated overhead. Other than software development costs that qualify for capitalization, as discussed above, research anddevelopment costs are expensed as incurred.General and administrativeGeneral and administrative expenses consist primarily of personnel costs associated with the Company’s executive, finance, legal, humanresources, compliance, and other administrative personnel, as well as accounting and legal professional services fees, other corporate-relatedexpenses and allocated overhead. General and administrative expenses also include amortization of covenant not to compete and tradenameintangible assets, the change in value of the contingent consideration, acquisition-related costs of business combinations, costs associated withthe secondary offering, and costs associated with the shelf offering.Stock-based compensationThe Company accounts for stock-based compensation awards granted to employees and directors based on the awards’ estimated grantdate fair value. The Company estimates the fair value of its stock options using the Black-Scholes option-pricing model. For awards that vestsolely based on continued service (“service-only vesting conditions”), the resulting fair value is recognized on a straight-line basis over the periodduring which an employee is required to provide service in exchange for the award, usually the vesting period, which is generally four years. TheCompany recognizes the fair value of stock options which contain performance conditions based upon the probability of the performanceconditions being met, using the graded vesting method. On January 1, 2017, the Company changed its accounting policy to account for forfeitureswhen they occur rather than estimate a forfeiture rate.Determining the grant date fair value of options using the Black-Scholes option-pricing model requires management to make assumptionsand judgments. These estimates involve inherent uncertainties and, if different assumptions had been used, stock-based compensation expensecould have been materially different from the amounts recorded.The assumptions and estimates are as follows:Value per share of the Company’s common stock. Prior to the Company’s initial public offering in October 2016, because there was nopublic market for the Company’s common stock, the Company’s management, with the assistance of a third-party valuation specialist, determinedthe fair value of the Company’s common stock at the time of the grant of stock options by considering a number of objective and subjectivefactors, including the Company’s actual operating and financial performance, market conditions and performance of comparable publicly-tradedcompanies, developments and milestones in the Company, the likelihood of achieving a liquidity event and transactions involving the Company’scommon stock, among other factors. The fair value of the underlying common stock was determined by the Company’s board of directors throughthe date of the initial public offering. The fair value of the Company’s common stock was determined in accordance with applicable elements of thepractice aid issued by the American Institute of Certified Public Accountants, Valuation of Privately Held Company Equity Securities Issued asCompensation. For awards granted subsequent to the Company’s initial public offering, the fair value of common stock is based on the closingprice of the Company’s common stock, as reported on the NASDAQ, on the date of grant.Expected volatility. The Company determines the expected volatility based on historical average volatilities of similar publicly-tradedcompanies corresponding to the expected term of the awards.Expected term. The Company determines the expected term of awards which contain service-only vesting conditions using the simplifiedapproach, in which the expected term of an award is presumed to be the mid-point between the vesting date and the expiration date of the award,as the Company does not have sufficient historical data relating to stock option exercises.Risk-free interest rate. The risk-free interest rate is based on the United States Treasury yield curve in effect during the period the optionswere granted corresponding to the expected term of the awards.Estimated dividend yield. The estimated dividend yield is zero, as the Company does not currently intend to declare dividends in theforeseeable future.85 The following information represents the weighted average of the assumptions used in the Black-Scholes option-pricing model for stockoptions granted: Year Ended December 31, 2017 2016 2015 Expected term (years) 6.2 6.3 6.3 Expected volatility 47.0% 47.5% 49.6%Risk free interest rate 2.1% 1.4% 1.7%Expected dividends — — — Income taxesThe Company accounts for income taxes in accordance with ASC 740, Income Taxes. ASC 740 requires the recognition of deferred taxassets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases ofassets and liabilities. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in theyears in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets andliabilities is recognized in the consolidated statements of operations in the period that includes the enactment date. A valuation allowance isrecorded when it is more likely than not that some of the deferred tax assets will not be realized.The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustainedon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financialstatements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized. TheCompany recognizes interest and penalties accrued with respect to uncertain tax positions, if any, in the provision for income taxes in theconsolidated statements of operations.Net loss per shareBasic and diluted loss per share is calculated by dividing net loss by the weighted average number of shares of common stock outstanding.As the Company has net losses for the periods presented, all potentially dilutive common stock, which are comprised of stock options andwarrants, are antidilutive.Foreign currencyThe Company’s foreign subsidiaries’ functional currency is the U.S. Dollar. The foreign exchange impacts of remeasuring the foreignsubsidiaries’ local currency to the U.S. Dollar functional currency is recorded in general and administrative expenses, net in the Company’sconsolidated statements of operations. Monetary assets and liabilities of foreign operations are remeasured at balance sheet date exchange rates,non-monetary assets and liabilities and equity are remeasured at the historical exchange rates, while results of operations are remeasured ataverage exchange rates in effect for the period. Foreign currency transaction gains (losses) totaled $0.4 million, $(28,000), and $(0.3) million forthe years ended December 31, 2017, 2016, and 2015, respectively. Recent accounting pronouncementsUnder the Jumpstart Our Business Startups Act, or the JOBS Act, the Company meets the definition of an emerging growth company. TheCompany has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant toSection 107(b) of the JOBS Act.Recently issued accounting pronouncements not yet adopted In May 2014, the Financial Accounting Standards Board (the “FASB”) issued guidance related to revenue from contracts with customers.Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects theconsideration that is expected to be received for those goods or services. In addition, the standard requires disclosure of the nature, amount,timing, and uncertainty of revenue and cash flows arising from contracts with customers. The updated standard will replace all existing revenuerecognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transitionmethod. The Company will adopt the new revenue guidance in the first quarter of 2018 using the retrospective method to restate each priorreporting period presented. In preparation for adoption of the standard, we are implementing internal controls and86 key system functionality to enable the preparation of financial information. The most significant impact of the standard relates to our accounting forthe incremental costs of obtaining a contract, such as sales commissions. Sales commissions are generally not paid upon contract renewals, andaccordingly, under the new revenue standard, commissions will be recognized over an estimated period of benefit of five years rather than over thenon-cancelable contract term under existing guidance, resulting in a larger deferral of commissions each period and a reduction in operatingexpenses in the historical consolidated financial statements. The new standard will also impact the Company’s accounting for on-premisesolutions which includes software license, maintenance and support fees on Runbook solutions. Under the existing guidance, the Companygenerally does not have VSOE of all the undelivered elements, generally maintenance and support and professional services, in its on-premisesoftware arrangements, and so the Company recognizes software license revenues over the period of the undelivered elements. Under the newstandard, the Company will recognize software license revenue at the time of delivery which will generally result in an acceleration of revenuerecognition. Revenue recognition related to subscription fees for access to the Company’s SaaS platform and corresponding professional serviceswill remain substantially unchanged. The Company expects that the adoption of the new standard will result in a reduction of revenues in the rangeof $1.0 million to $2.0 million for the year ended December 31, 2017 and an increase in revenues in the range of $3.0 million to $5.0 million for theyear ended December 31, 2016, primarily due to the change in timing of recognition of software license revenue. Additionally, the Companyexpects that the adoption of the new standard will result in a reduction of operating expenses in the range of $5.0 million to $7.0 million for each ofthe years ended December 31, 2017 and 2016, related to its accounting for the incremental costs of obtaining a contract.In February 2016, the FASB issued new guidance which significantly changes the accounting for leases. The new guidance requires alessee recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to usethe underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy electionby class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expensefor such leases generally on a straight-line basis over the lease term. For income statement purposes, the new guidance retained a dual model,requiring leases to be classified as either operating or financing. Operating leases will result in straight-line expense while finance leases will resultin a front-loaded expense pattern similar to existing capital lease guidance. For statement of cash flow purposes, the new guidance also retainedthe existing dual method, where cash payments for operating leases are reflected in cash flows from operating activities and principal and interestpayments for finance leases are reflected in cash flows from financing activities and cash flows from operating activities, respectively. The newguidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The new guidance requiresthe recognition and measurement of leases at the beginning of the earliest period presented using a modified retrospective approach. The use ofthe modified retrospective approach allows an entity to use a number of practical expedients in the application of this new guidance. Although theCompany is evaluating the impact of adopting this guidance on its consolidated financial statements, the Company expects that most of itsoperating lease commitments will be recognized as operating lease liabilities and right-of-use assets upon adoption of the new guidance.In June 2016, the FASB issued guidance which requires that financial assets measured at amortized costs be presented at the net amountexpected to be collected. This guidance amends the accounting for credit losses for available-for-sale securities and purchased financial assetswith credit deterioration. This guidance is effective for annual periods beginning after December 15, 2019, and interim periods within those annualperiods. Early adoption is permitted for any interim or annual period after December 15, 2018. The Company has not determined the impact of thisguidance on its consolidated financial statements.In November 2016, the FASB issued guidance which requires that restricted cash and restricted cash equivalents be included with cash andcash equivalents when reconciling the beginning and ending total amounts shown on the statement of cash flows. This guidance is effective forfiscal years beginning after December 15, 2017, and interim periods within those years, and should be applied using a retrospective transitionmethod to each period presented. The adoption of this guidance is not expected to have a material impact on the Company’s consolidatedstatements of cash flows.In February 2017, the FASB issued guidance which simplifies the subsequent measurement of goodwill by no longer requiring an entity todetermine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets andliabilities as if that reporting unit had been acquired in a business combination. Under this new guidance, an entity would perform its goodwillimpairment test by comparing the fair value of a reporting unit with its carrying amount and would recognize an impairment charge for the amountby which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized would not exceed the total amount of goodwillallocated to that reporting unit. Additionally, an entity would consider income tax effects from any tax deductible goodwill on the carrying amount ofthe reporting unit when measuring the goodwill impairment loss, if applicable. Under the new guidance, an entity continues to have the option toperform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This guidance is effective forfiscal years beginning after87 December 15, 2019 and interim periods within those years. Early adoption is permitted for interim or annual goodwill impairment tests performedon testing dates after January 1, 2017. The Company adopted this standard effective January 1, 2018, and the adoption of this standard did nothave a material impact on the Company’s consolidated financial statements.In March 2017, the FASB issued guidance which shortens the amortization period for certain purchased callable debt securities held at apremium. Under this new guidance, an entity would shorten the amortization period of the premium to the earliest call date. This guidance iseffective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted,including adoption in an interim period. The Company has not determined the impact of this guidance on its consolidated financial statements.In May 2017, the FASB issued guidance to clarify which changes to the terms or conditions of a share-based payment award require anentity to apply modification accounting. Under this guidance an entity should account for the effects of a modification unless all the following aremet: 1) The fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified. Ifthe modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required toestimate the value immediately before and after the modification; 2) The vesting conditions of the modified award are the same as the vestingconditions of the original award immediately before the original award is modified; and 3) The classification of the modified award as an equityinstrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. Theamendments in this guidance are effective for all entities for annual periods, and interim periods within those annual periods, beginning afterDecember 15, 2017 and should be applied prospectively to an award modified on or after the adoption date. Early adoption is permitted, includingadoption in any interim period. The Company adopted this standard effective January 1, 2018, and will apply this guidance to modifications ofstock-based compensation arrangements, if any, after this date.In July 2017, the FASB issued guidance which changes the classification analysis of certain equity-linked financial instruments orembedded features, for example warrants and convertible debt, with down round features. When determining whether certain financial instrumentsshould be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether theinstrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. Asa result, a freestanding equity-linked financial instrument or embedded conversion option no longer would be accounted for as a derivative liabilityat fair value as a result of the existence of a down round feature. This new guidance also amends existing earnings per share guidance torecognize the effect of the down round feature when it is triggered. This guidance is effective for annual periods beginning after December 15,2018, and interim periods within those annual periods. Early adoption is permitted, including adoption in an interim period. If the guidance isadopted in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. This newguidance may be adopted on a modified retrospective approach by means of a cumulative-effect adjustment to the statement of financial positionas of the beginning of the first fiscal year and interim period in which the guidance is effective or on a full retrospective basis. The Company’swarrants to purchase common stock, which were exercised in May 2017, were liability classified and recorded at fair value each period as a resultof down round features. The Company is assessing the impact of this guidance and its adoption method.Recently adopted accounting pronouncementsIn March 2016, the FASB issued new guidance to simplify various aspects relating to accounting for stock-based compensation and relatedtax impacts, the classification of excess tax benefits on the statement of cash flows, statutory tax withholding requirements, and other stock-based compensation classification matters. The guidance was effective for annual reporting periods beginning after December 15, 2016 andinterim periods within those annual periods. The Company adopted this guidance during the first quarter ended March 31, 2017. Upon adoption,the Company changed its accounting policy to account for forfeitures when they occur rather than estimate a forfeiture rate. The impact of thischange in policy increased the Company’s accumulated deficit and additional paid-in capital by $0.1 million as of January 1, 2017. The newguidance also requires the Company to record, on a prospective basis, the income tax effects of stock-based compensation awards in the incomestatement as discrete items, subject to deferred tax asset valuation allowance considerations, in the reporting period in which they occur, whichwill increase volatility in the Company’s income tax provision in the future to the extent that the Company is able to realize the tax benefits. Inaddition, upon adoption previously unrecognized tax benefits were recorded as an adjustment to accumulated deficit, subject to assessment forthe need for a deferred tax asset valuation allowance, as of January 1, 2017. The Company had $36.7 million of net operating losses related to taxbenefits for stock-based compensation awards at December 31, 2016 which were not recorded as deferred tax assets. As the Company has a fullvaluation allowance against its deferred tax assets, the adoption of this guidance did not have a material impact on the Company’s financialstatements.88 Note 3—Property and EquipmentProperty and equipment consisted of the following (in thousands): December 31, 2017 2016 Computers and equipment $4,919 $3,287 Purchased software 4,934 3,829 Furniture and fixtures 2,204 1,725 Leasehold improvements 9,075 6,888 Construction in progress 180 523 21,312 16,252 Less: accumulated depreciation and amortization (8,543) (4,934) $12,769 $11,318 Depreciation and amortization expense related to property and equipment was $4.0 million, $3.1 million, and $1.8 million for the years endedDecember 31, 2017, 2016, and 2015, respectively.Software and construction in progress included assets held under capital lease of $1.6 million at December 31, 2017 and 2016, reduced byrelated accumulated amortization thereon of $1.0 million and $0.4 million, respectively. Note 4 – Business CombinationOn August 31, 2016, the Company acquired all the issued and outstanding capital stock of Runbook, a Netherlands-based provider offinancial close automation software and integration solutions for SAP. The purpose of the acquisition was to enhance the Company’s position as aleading provider of software solutions to automate the financial close process for SAP customers and supports the Company’s Europeanexpansion strategy. The acquisition has been accounted for as a business combination under GAAP. The total purchase consideration was approximately $34.1 million which was paid in cash. The purchase consideration is subject to a finalworking capital adjustment, which has not yet been finalized. Any adjustment will be recorded in the consolidated statement of operations in theperiod of settlement. A portion of the purchase price totaling $3.1 million was paid into escrow for indemnification obligations relating to potentialbreach of representations and warranties of the sellers. Any amounts remaining in escrow after satisfaction of any resolved claims will be releasedfrom escrow. For the year ended December 31, 2016, acquisition-related costs incurred by the Company of approximately $1.6 million wereexpensed as incurred and are included in general and administrative expenses in the consolidated statements of operations.The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the date of the acquisition (inthousands): Total cash consideration to selling shareholders $34,052 Assets acquired and liabilities assumed Cash and cash equivalents 2,564 Accounts receivable 2,518 Prepaid expenses and other current assets 718 Property and equipment 427 Intangible assets 9,790 Accounts payable (285)Accrued expenses and other current liabilities (376)Deferred revenue (501)Net deferred income tax liabilities (2,787)Net assets 12,068 Goodwill $21,984 89 The Company believes the amount of goodwill resulting from the acquisition is primarily attributable to expected synergies from assembledworkforce, an increase in development capabilities, increased offerings to customers, and enhanced opportunities for growth and innovation. Thegoodwill resulting from the acquisition is not tax deductible.To determine the estimated fair value of intangible assets acquired, the Company engaged a third-party valuation specialist to assistmanagement. The fair value measurements of the intangible assets were based primarily on significant unobservable inputs and thus represent alevel 3 measurement as defined in ASC 820. The acquired intangible asset categories, fair value and amortization periods, were as follows: AmortizationPeriod Fair Value(in thousands) Trade name 1 year $20 Developed technology 8 years 5,710 Non-compete agreements 2 years 180 Customer relationships 10 years 3,880 $9,790 The weighted average lives of intangible assets at the acquisition date was 8.7 years. Unaudited pro forma informationThe following table presents the Company’s unaudited pro forma information as if the acquisition occurred on January 1, 2015 (inthousands): Year Ended December 31, 2016 2015 Pro forma total revenues $128,196 $88,303 Pro forma net loss $(39,000) $(28,161)Pro forma net loss per share, basic and diluted $(0.92) $(0.69) The pro forma results reflect certain adjustments for the depreciation and amortization of the fair values of the intangible assets acquired,adjustments to revenue resulting from the fair value adjustment to deferred revenue, acquisition-related costs, and related tax adjustments. Suchpro forma amounts are not necessarily indicative of the results that actually would have occurred had the acquisition been completed on the dateindicated, nor is it indicative of the future operating results of the Company.The total amount of Runbook revenue and net loss included in the Company’s consolidated results of operations from the date of acquisitionto December 31, 2016 was $0.8 million and $1.7 million, respectively. 90 Note 5—Intangible Assets and GoodwillThe carrying value of intangible assets was as follows (in thousands): December 31, 2017 Gross CarryingAmount AccumulatedAmortization Net CarryingAmount Trade name $15,977 $(6,930) $9,047 Developed technology 42,558 (27,577) 14,981 Non-compete agreements 4,520 (3,882) 638 Customer relationships 31,783 (15,641) 16,142 $94,838 $(54,030) $40,808 December 31, 2016 Gross CarryingAmount AccumulatedAmortization Net CarryingAmount Trade name $15,977 $(5,361) $10,616 Developed technology 42,558 (20,694) 21,864 Non-compete agreements 4,520 (2,924) 1,596 Customer relationships 31,783 (11,741) 20,042 $94,838 $(40,720) $54,118 Amortization expense is included in the following functional statements of operations expense categories.

The Term Loan had a term of fiveyears and expired and was repayable on September 25, 2018. The Term Loan bore interest at (i) the greater of LIBOR or 1.5% plus (ii) 8%. InMarch 2016 and August 2016, the Company amended its credit facility to add an additional $5.0 million term loan (the “2016 Incremental TermLoan”) and to add an additional $30 million term loan (the “2016 Acquisition Term Loan”), respectively. Both the 2016 Incremental Term Loan andthe 2016 Acquisition Term Loan had similar terms and conditions to the original Term Loan, and both were subject to prepayment penalties if theCompany elected to repay the loans before the expiration date. The term loans bore interest at a rate of 9.5% per annum. Under the provisions ofeach term loan, the Company had the option to pay interest in varying amounts in cash or in payment in kind. For the years ended December 31,2016 and 2015, interest of $1.8 million and $2.1 million, respectively, was paid in kind, thereby increasing the outstanding principal. Interest paid inkind was due and payable at maturity of each term loan. In November 2016, the Company repaid in full all outstanding debt under the Company’scredit facility and terminated the agreement, as amended. In connection with the termination of the agreement, the Company paid a total ofapproximately $67.7 million, which included principal, accrued interest, paid in kind interest, and prepayment penalties. Prepayment penalties of$0.7 million were expensed to interest expense in November 2016 upon repayment and termination of the credit facility. For the year endedDecember 31, 2016, upon the termination of the credit facility, accumulated paid in kind interest of $6.4 million was repaid and has been classifiedin cash flows from operating activities. The Company incurred $1.1 million, $0.2 million and $0.5 million in transaction costs and fees payable to the lender related to theissuance of the Term Loan, the 2016 Incremental Term Loan, and the 2016 Acquisition Term Loan, respectively. These amounts, net ofamortization, had been presented as a discount against the carrying amount of the term loans. In November 2016, in connection with therepayment of the Company’s term loans and termination of its credit facility, the Company expensed the remaining unamortized debt issuancecosts of $1.1 million to interest expense in the consolidated statements of operations.In conjunction with Term Loan, the Company issued warrants to purchase 499,999 shares of common stock at an exercise price pershare of $5.00. The warrants were exercisable at any time by the holder and expired upon the earlier of ten years from the issuance date or thesale of the Company. In May 2017, warrants to purchase 499,999 shares of common stock were net exercised, resulting in the issuance of428,033 shares of common stock and, accordingly, there will be no further changes in the fair value. During the year ended December 31, 2016,the carrying value of the Term Loan was reduced by the fair value of the warrants at issuance of $1.4 million. The resulting debt discount wasbeing amortized over the term of the debt on a straight-line basis which approximates the effective interest method. The amortization of the debtdiscount was recorded in interest expense in the consolidated statements of operations. In November 2016, in connection with the repayment ofthe Company’s term loans and termination of its credit facility, the Company expensed the remaining unamortized debt issuance costs associatedwith the issuance of the warrants of $0.5 million to interest expense in the consolidated statements of operations. Note 8—Income Taxes92 The components of income (loss) before income taxes for the years ended December 31, 2017, 2016, and 2015 were as follows (inthousands): Year ended December 31, 2017 2016 2015 United States $(37,044) $(45,123) $(39,350)International (450) (623) 903 $(37,494) $(45,746) $(38,447) The components of the total provision for (benefit from) income taxes for the years ended December 31, 2017, 2016, and 2015 were asfollows (in thousands): Year ended December 31, 2017 2016 2015 Current Federal $— $— $— State 51 5 7 International 450 840 221 Total current tax expense 501 845 228 Deferred Federal — (6,086) (12,468)State — (202) (1,473)International 66 (1,144) — Total deferred tax provision (benefit) 66 (7,432) (13,941) Total provision for (benefit from) income taxes $567 $(6,587) $(13,713) A reconciliation of the statutory U.S. federal income tax rate to the Company’s effective tax rate for the years ended December 31, 2017,2016, and 2015 was as follows: Year ended December 31, 2017 2016 2015 Federal statutory income tax rate 34.0% 34.0% 34.0%State tax, net of federal benefit (0.1%) 3.0% 4.0%Federal tax credits 2.9% 1.2% 1.1%Change in valuation allowance (9.8%) (16.5%) (2.3%)Common stock warrants (3.2%) (4.4%) (0.4%)Foreign tax differential (1.8%) — — Windfall tax benefits, net related to stock-based compensation 13.4% — — Effect of rate and other changes on federal deferred taxes, net due to enactment of Tax Cuts and Jobs Act (33.7%) — — Other (3.2%) (2.9%) (0.7%) (1.5%) 14.4% 35.7% In December 2017, the U.S. Congress passed and the President signed legislation commonly referred to as the Tax Cuts and Jobs Act (“theTax Act”), which contains many significant changes to the U.S. tax laws including reducing the U.S. federal corporate tax rate from 35% to 21%and creating a territorial tax system with a onetime mandatory tax on previously deferred foreign earnings of U.S. subsidiaries. As the Companyhas a full valuation allowance against its U.S. deferred tax assets, the revaluation of net deferred tax assets resulting from the reduction in the U.Sfederal corporate income tax rate did not impact the Company’s effective tax rate. In addition, due to cumulative foreign deficits, no liability forforeign earnings and profits has been established. Additional guidance may be issued by the U.S. Treasury Department, the IRS or other standard-setting bodies, which may result in adjustments to the amounts recorded. 93 Significant components of the Company’s deferred tax assets and liabilities at December 31, 2017 and 2016 were as follows (in thousands): Year ended December 31, 2017 2016 Deferred tax assets Accrued expenses and other current liabilities $1,462 $1,065 Business credits 5,197 2,913 Stock-based compensation 3,961 4,393 Net operating loss carryover 29,590 21,151 Other 2,052 1,253 Total deferred tax assets 42,262 30,775 Less: valuation allowance (29,201) (8,489)Deferred tax assets, net of valuation allowance 13,061 22,286 Deferred tax liabilities Property and equipment (1,589) (1,250)Intangible assets (11,287) (20,439)Prepaid expenses (1,513) (1,859)Total deferred tax liabilities (14,389) (23,548)Net deferred taxes $(1,328) $(1,262) ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to theextent that management assesses that realization is "more likely than not." A valuation allowance is recorded when it is more likely than not thatsome of the deferred tax assets will not be realized. Realization of future tax benefits is dependent on the Company’s ability to generate sufficienttaxable income within the carryforward period. For financial reporting purposes, the Company has incurred losses for each of the past three years.Based on available objective evidence, including the Company’s history of losses, management believes it is more likely than not that the netdeferred tax assets will not be fully realizable. Accordingly, the Company provided a valuation allowance against its federal and state deferred taxassets. The Company’s foreign tax jurisdictions were in a net deferred tax liability position at December 31, 2017.The change in the valuation allowance was as follows (in thousands). Year Ended December 31, 2017 2016 2015 Valuation allowance, at beginning of year $8,489 $887 $— Increase in valuation allowance recorded through earnings 6,814 7,602 887 Increase in valuation allowance as result of adoption of ASU 2016-09 13,898 — — Valuation allowance, at end of year $29,201 $8,489 $887 The Company did not provide for United States income taxes on the undistributed earnings and other outside temporary differences offoreign subsidiaries as they are considered indefinitely reinvested outside the United States. At December 31, 2017 and 2016 the amount oftemporary differences related to undistributed earnings and other outside temporary differences upon which United States income taxes have notbeen provided is immaterial to these consolidated financial statements. At December 31, 2017, the Company had consolidated federal and state net operating loss carryforwards available to offset future taxableincome of approximately $122.3 million and $60.3 million, respectively. The federal losses will begin to expire in 2033, and the state losses willbegin to expire between 2023 and 2033, depending on the jurisdiction. The Company has federal research and development credits and foreigntax credits of $2.2 million and $1.2 million, respectively, which begin to expire on 2033 and 2023, respectively. The Company has state researchand development credits and enterprise zone credits of $2.6 million and $0.6 million, respectively, which are indefinite in expiration and begin toexpire by 2023, respectively. Pursuant to Internal Revenue Code Section 382, use of the94 Company’s net operating loss carryforwards may be limited if the Company experiences a cumulative change in ownership of more than 50%over a three-year period. The following is a roll forward of the Company’s total gross unrecognized tax benefits (in thousands): Year ended December 31, 2017 2016 2015 Beginning gross unrecognized tax benefits $382 $278 $188 Increases related to prior year tax positions 38 — — Increases related to current year tax positions 252 104 90 Ending gross unrecognized tax benefits $672 $382 $278 At December 31, 2017, the realization of unrecognized tax benefits are not expected to impact the effective rate due to a full valuation onfederal and state deferred taxes. The Company has not recorded any interest or penalties in its provision for (benefit from) income taxes for theyears ended December 31, 2017, 2016, and 2015 and no such amounts have been accrued at December 31, 2017 and 2016. The Company files U.S. federal, various state and foreign income tax returns. In the normal course of business, the Company is subject toexamination by taxing authorities. The tax years 2015 and 2016 remain subject to examination for federal purposes. Generally, state and foreigntax authorities may examine the Company’s tax returns for four years and five years, respectively, from the date an income tax return is filed.However, the taxing authorities may continue to adjust the Company’s federal and state net operating loss carryforwards until the statute oflimitations closes on the tax years in which the federal and state net operating losses are utilized.The Company does not anticipate either material changes in the total amount or composition of its unrecognized tax benefits within 12months of the reporting date. Note 9—Net Loss per ShareThe following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share amounts): Year Ended December 31, 2017 2016 2015 Numerator: Net loss $(38,061) $(39,159) $(24,734)Denominator: Weighted average shares 52,161 42,497 40,579 Add: Dilutive effect of securities — — — Shares used to calculate diluted net loss per share 52,161 42,497 40,579 Basic net loss per share $(0.73) $(0.92) $(0.61)Diluted net loss per share $(0.73) $(0.92) $(0.61) 95 The following potentially dilutive shares were excluded from the calculation of diluted net loss per share attributable to common stockholdersbecause they were anti-dilutive: December 31, 2017 2016 2015 Stock options with service-only vesting conditions 5,019 5,874 5,904 Stock options with performance conditions 683 683 — Common stock warrants — 500 500 Restricted stock units 2 — — Total shares excluded from net loss per share 5,704 7,057 6,404 Note 10—Contingent ConsiderationOn September 3, 2013, the Company acquired BlackLine Systems, Inc. Under the terms of the acquisition agreement, BlackLine Systems,Inc.’s option holders were allowed to cancel their stock option rights and receive a cash payment equal to the amount of calculated gain (lessapplicable expense and other items) had they exercised their stock options and then sold their common shares as part of the acquisition. As acondition of the acquisition, the Company is required to pay additional cash consideration to certain equity holders if the Company realizes a taxbenefit from the use of net operating losses generated from the stock option exercises concurrent with the acquisition. The maximum contingentcash consideration to be distributed is $8.0 million. The fair value of the contingent consideration was $5.9 million and $5.2 million atDecember 31, 2017 and 2016, respectively. See Note 2 for additional information regarding the valuation of the contingent consideration.Note 11—Commitments and ContingenciesOperating leases—The Company has various non-cancelable operating leases for its corporate and international offices. These leasesexpire at various times through 2024. Certain lease agreements contain renewal options, rent abatement and escalation clauses. The Companyrecognizes rent expense on a straight-line basis over the lease term, commencing when the Company takes possession of the property. Certain ofthe Company’s office leases entitle the Company to receive a tenant allowance from the landlord. The Company records tenant allowances as adeferred rent credit, which the Company amortizes on a straight-line basis, as a reduction of rent expense, over the term of the underlying lease.Total rent expense under the operating leases was approximately $3.4 million, $2.9 million, and $2.5 million for the years ended December 31,2017, 2016, and 2015, respectively.Future minimum lease payments under non-cancelable operating leases at December 31, 2017 was (in thousands): 2018 $5,380 2019 4,269 2020 3,403 2021 2,631 2022 2,598 Thereafter 2,876 $21,157 Purchase obligations— At December 31, 2017, the Company had $2.5 million of non-cancelable purchase obligations primarily related to futuresales and user conferences. Capital leases—The Company leases computer software from various parties under capital lease agreements. Outstanding principalpayments under capital lease obligations were $0.4 million at December 31, 2017, which is payable in full in 2018.Litigation—From time to time, the Company may become subject to legal proceedings, claims and litigation arising in the ordinary courseof business. The Company is not currently a party to any legal proceedings, nor is it aware of any96 pending or threatened litigation, that would have a material adverse effect on the Company’s business, operating results, cash flows, or financialcondition should such litigation be resolved unfavorably.Indemnification—In the ordinary course of business, the Company may provide indemnification of varying scope and terms to customers,vendors, investors, directors, and officers with respect to certain matters, including, but not limited to, losses arising out of our breach of suchagreements, services to be provided by the Company, or from intellectual property infringement claims made by third parties. Theseindemnification provisions may survive termination of the underlying agreement and the maximum potential amount of future payments theCompany could be required to make under these indemnification provisions may not be subject to maximum loss clauses. The maximum potentialamount of future payments the Company could be required to make under these indemnification provisions is indeterminable. The Company hasnever paid a material claim, nor has it been sued in connection with these indemnification arrangements. At December 31, 2017 and 2016, theCompany has not accrued a liability for these indemnification arrangements because the likelihood of incurring a payment obligation, if any, inconnection with these indemnification arrangements was not probable or reasonably estimable.Note 12—CapitalizationAt December 31, 2017, the authorized capital stock of the Company consisted of 500 million shares of common stock and 50 million sharesof preferred stock. No shares of preferred stock were issued and outstanding at December 31, 2017. The board of directors can determine thevoting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of the preferred stock.On January 14, 2016, the board of directors approved the retirement of 47,000 shares of treasury stock.In September 2016, the Company raised gross proceeds of $3.1 million from the sale of 192,187 shares of common stock to formerRunbook employees.On November 2, 2016, the Company completed its initial public offering in which it issued and sold 9,890,000 shares of its common stock,which included the exercise in full of the underwriters’ option to purchase an additional 1,290,000 shares at an initial offering price of $17.00 pershare. The Company received proceeds from the offering of approximately $151.9 million after deducting underwriting discounts and commissionsand other offering expenses. Note 13—Equity Awards2014 and 2016 PlansOn March 3, 2014, the Company adopted the 2014 Stock Incentive Plan (the “2014 Plan”). In November 2016, upon the completion of theCompany’s initial public offering, the Company adopted the 2016 Equity Incentive Plan (the “2016 Plan”) and determined that it will no longer grantany additional awards under the 2014 Plan. However, the 2014 Plan continues to govern the terms and conditions of the outstanding awardspreviously granted under the 2014 plan. Upon the adoption of the 2016 Plan, the maximum number of shares issuable was 6.2 million, plus anumber of shares equal to the number of shares subject to outstanding awards granted under the 2014 Plan after the date the 2014 Plan isterminated without having been exercised in full. The Company’s board of directors may grant stock options and restricted stock units toemployees, directors and consultants under the 2016 Plan. The aggregate number of shares available under the 2016 Plan and the number ofshares subject to outstanding options automatically adjusts for any changes in the Company’s outstanding common stock by reason of anyrecapitalization, spin-off, reorganization, reclassification, stock dividend, stock split, reverse stock split, or similar transaction. Stock options andrestricted stock units generally vest over four years and have contractual terms of ten years.At December 31, 2017, 8.3 million shares were available for issuance under the 2016 Plan.97 Stock options with service-only vesting conditionsA summary of the Company’s stock option activity and related information for awards that contain service-only vesting conditions was asfollows: Shares(in thousands) WeightedAverageExercise PriceWeightedAverageRemainingContractualTerm(Years) AggregateIntrinsicValue(inthousands) Outstanding at December 31, 2016 5,874 $10.09 8.0 $103,038 Granted 809 $31.75 Exercised (1,288) $8.23 Forfeited/canceled (376) $12.27 Outstanding at December 31, 2017 5,019 $13.90 7.5 $95,353 Exercisable at December 31, 2017 1,994 $9.34 6.9 $46,780 The weighted average grant date fair value per share of options granted during the years ended December 31, 2017, 2016, and 2015 thatcontain service only vesting conditions were $15.20, $6.78, and $7.04, respectively. The aggregate intrinsic value of options exercised that containservice only vesting conditions during the years ended December 31, 2017, 2016, and 2015 were $31.4 million, $4.8 million, and $2.6 million,respectively. Cash received from the exercise of stock options for the years ended December 31, 2017, 2016, and 2015 was $10.4 million, $2.9million, and $1.4 million, respectively.Unrecognized compensation expense relating to stock options that contain service only vesting conditions was $20.2 million atDecember 31, 2017, which is expected to be recognized over a weighted-average period of 2.7 years.Stock options with performance conditionsIn October 2016, the Company granted options to purchase 682,800 shares of common stock at an exercise price of $14.00 per share totwo executive officers that vest upon meeting certain performance conditions and continued service. The performance conditions include meetingyearly cash flow targets and cumulative annual recurring revenue targets through 2019. If each yearly cash flow target is met through 2019, but thefull cumulative annual recurring target through 2019 is not met, the executive officers are still able to vest in the award if an additional cash flowtarget for 2020 and a cumulative annual recurring revenue target through 2020 are achieved. The cash flow performance targets for each year aredetermined concurrently with the annual budget process and because each yearly target has not yet been set, no grant date for the options hasbeen established. At December 31, 2017, the Company has determined that the achievement of the performance targets is not probable and,accordingly, no stock-based compensation expense has been recorded for these awards. To the extent that the awards become probable ofvesting prior to the grant date, the amount of compensation cost to be recognized will be based on the then fair value of the options. The fair valueof the options will be remeasured each period until a grant date has been established. Accordingly, stock-based compensation cost, if any, to berecognized will depend on the value of the stock options when all performance conditions have been set and whether the performance conditionsare probable of being achieved. Restricted stock unitsThe following table summarizes activity for restricted stock units: Restricted Stock Units(in thousands)WeightedAverageGrant DateFair ValueNonvested at December 31, 2016 — $— Granted 2 $34.12 Nonvested at December 31, 2017 2 $34.12 98 At December 31, 2017, the intrinsic value of nonvested restricted stock units was $53,000. At December 31, 2017, total unrecognizedcompensation cost related to nonvested restricted stock units was $32,000 and was expected to be recognized over a weighted-average period of0.3 years.Stock-based compensation expenseStock-based compensation expense recorded in the Company’s consolidated statements of operations was as follows (in thousands): Year Ended December 31, 2017 2016 2015 Cost of revenues $1,149 $715 $466 Sales and marketing 10,811 2,490 2,418 Research and development 767 809 588 General and administrative 3,317 2,512 2,025 $16,044 $6,526 $5,497 Stock-based compensation capitalized as an asset was $0.1 million in each of the years ended December 31, 2017, 2016, and 2015. Due to the full valuation allowance provided on the Company's net deferred tax assets, the Company has not recorded any tax benefitsattributable to stock-based awards for the years ended December 31, 2017, 2016, and 2015. On July 21, 2017, the Company modified the vesting terms of options to purchase 219,000 shares of common stock to a time-basedvesting schedule, for eight employees. Prior to the modification, the options vested solely upon a change in control of the Company. The Companyrecorded $6.6 million of stock-based compensation in the year ended December 31, 2017. At December 31, 2017, the total unrecognizedcompensation cost related to these options was $0.6 million.Note 14—Defined Contribution PlanThe Company sponsors a defined contribution retirement plan (the “Plan”) that covers substantially all domestic employees. The Companymakes matching contributions of 100% of each $1 of the employee’s contribution up to the first 3% of the employee’s bi-weekly compensation and50% of each $1 of the employee’s contribution up to the next 2% of the employee’s bi-weekly compensation. Matching contributions to the Planrecorded in the Company’s consolidated statements of operations totaled $2.2 million, $2.3 million, and $1.7 million for the years ended December31, 2017, 2016, and 2015, respectively.Note 15—Related-Party TransactionsThe Company had no material related-party transactions for the years ended December 31, 2017 and 2016.

Item 9A.Controls and ProceduresEvaluation of Disclosure Controls and ProceduresDisclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act, as amended, or “theExchange Act” means controls and other procedures of a company that are designed to provide reasonable assurance that information required tobe disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, withinthe time periods specified in the SEC’s rules and forms; and that such information is accumulated and communicated to the company’smanagement, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding requireddisclosure. Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness ofour disclosure controls and procedures at December 31, 2017, the last day of the period covered by this Annual Report. Based on this evaluation,our principal executive officer and principal financial officer have concluded that, at December 31, 2017, our disclosure controls and procedureswere effective at the reasonable assurance level.Limitations on the Effectiveness of Controls and ProceduresIn designing and evaluating our disclosure controls and procedures and internal control over financial reporting, management recognizes thatany controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving thedesired control objectives. In addition, the design of disclosure controls and procedures and internal control over financial reporting must reflect thefact that there are resource constraints and our management is required to apply judgment in evaluating the benefits of possible controls andprocedures relative to their costs. The design of any disclosure controls and procedures and internal control over financial reporting also is basedin part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving itsstated goals under all potential future conditions.Management’s Annual Report on Internal Control over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act).Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in"Internal Control - Integrated Framework" (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based onthis evaluation, management concluded that the Company's internal control over financial reporting was effective at December 31, 2017.This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm due to atransition period established by the Jumpstart Our Business Startups Act, or Jobs Act, for emerging growth companies.Changes in Internal Control over Financial ReportingDuring the quarter ended December 31, 2017, in order to facilitate our adoption of the new revenue recognition accounting standard onJanuary 1, 2018, we implemented internal controls to help ensure we properly evaluated our customer contracts and assessed the impact to ourconsolidated financial statements. We expect to continue to implement additional internal controls related to the adoption of this standard in thefirst quarter of 2018.There were no other changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during the quarter ended December 31, 2017 that have materially affected, or arereasonably likely to materially affect, our internal control over financial reporting.
