We sell our platform improves their healthcare experience,as a suite of branded and white-labeled digital health navigation applications to large U.S. employers and health plans. We also sell product offerings through partnerships with large benefits consultants and health plans, with a highly-engaging, seamlessfocus on serving large U.S. employers.

In July 2019, we expanded our strategy to include health plans as potential customers and to package our product offerings to support user experiences beyond those we offered through our Castlight-powered websites and applications. In addition, we expanded our offerings to incorporate high-touch, human support, enabled by our technology platform, in addition to the mobile application and web experience for users, which we call Castlight Care Guides.

Since this strategic expansion, we demonstrated proof points for our expanded strategy, including:

• In October 2019, we announced an enterprise license agreement with Anthem, Inc. (“Anthem”), the largest for-profit managed health care company in the Blue Cross Blue Shield Association, that provides Anthem with access to key components of our platform and expands Engage, a white-labeled version of our digital solutions.

In July 2020, we entered into an agreement with Cigna Corporation (“Cigna”), a global health services company, to support a portion of Cigna’s Taft-Hartley and Federal Business segment with our healthcare navigation technology.

• In the third quarter of 2020, our Castlight Care Guides offering became generally available as a supplemental service for our customers. From Castlight’s launch, we have offered users both digital applications and telephonic support. In parallel with the roadmap for our digital platform, we have invested in and expanded our phone-based support services.

The U.S. Healthcare Industry and Our Opportunity


Health benefits is oneWe believe Castlight has a significant opportunity to help existing and prospective customers and users navigate the major economic and social challenges associated with the U.S. healthcare system and benefit from the growing market for high-tech and high-touch navigation services. We see the following industry trends affecting employers, health plans and individual users as potential long-term growth drivers for our business.

Large Employers. Our historical focus has been on large employers of the largest categories of spend for U.S. employers, and is also an area of increasing complexity for employers and employees:healthcare market. We continue to see significant opportunities within this customer category.


Employers play a significant role in U.S. healthcare benefits spending. According to Thethe Centers for Medicare and Medicaid Services (“CMS”), U.S.employer-sponsored private health insurance spending is estimated to be $1.21totaled $1.1 trillion in 2017 and is expected2019, up 4.3% year-over-year. More than half of this amount was from private employer contributions to health insurance premiums. CMS forecasted these expenditures to grow at a compoundan average annual growth rate of 5.3%4.6% from 2018 to 2028.

Nevertheless, employees continue to struggle to understand and utilize their benefits, limiting the effectiveness of employer cost and quality initiatives. Studies continue to demonstrate significant underutilization of such benefits. The COVID-19 pandemic expanded employee needs, as almost half of employees skipped care, 45% of employees experienced behavioral health needs, and a majority of employees with chronic conditions delayed important care.

Based on these trends, large employers are increasingly interested in navigation technologies and services such as ours, to increase employee engagement, lower costs and improve outcomes. The Business Group on Health ("BGH") published a survey in August 2020 that listed its large employer members’ top healthcare initiatives for 2021, which include:

Implementing more virtual care solutions;

Expanding access to mental health services;
Deploying a more focused strategy on high-cost claims;
Expanding “centers of excellence” — programs with concentrated expertise in a particular medical area — to include more conditions to lower costs; and
Implementing high performance networks.

We believe Castlight has a key role to play in helping large U.S. employers and their employees address their respective health benefit challenges through 2022.personalized health navigation solutions, especially as large employers continue to respond to the changing healthcare landscape during the COVID-19 pandemic.


Employers seekHealth Plans. Given the scalability and demonstrated medical cost savings of our platform, we also believe there is a significant market opportunity for us to deploy more digitaloffer our platform to health offeringsplans. Overall U.S. healthcare spending is projected to improve employee satisfaction and outcomes but are faced with evaluating and managing an ever-increasing number of digital health point solutionscontinue to grow each year for their employees. Rock Healththe foreseeable future. CMS estimates that moreU.S. national health expenditures totaled $3.8 trillion in 2019, an increase of 4.5% year-over-year. CMS expects national health expenditures to increase at an average annual growth rate of 5.4% from 2018 to 2028, totaling approximately $6.2 trillion in 2028. CMS estimates that U.S. national health expenditures were approximately 17.8% of gross domestic product in 2019 and are projected to increase to 19.7% in 2028. This is significantly higher than $20 billion was investedmost other developed nations.

However, there is little evidence that these massive U.S. healthcare outlays are efficient or result in better outcomes for Americans. Research published in the October 2019 edition of the Journal of the American Medical Association estimates that waste comprises approximately 25% of U.S. digital health companies from 2013healthcare spending across categories, including failure of care delivery and coordination, over-treatment or low-value care, pricing failure, fraud and abuse and administrative complexity.

In addition to 2017, across more than 1,400 funding rounds. Although, this explosion in digital health options has been overwhelming for human resource executives responsiblethe large spending and inadequate value for health benefits evaluation, selectionplans, potential regulatory changes and spend, these solutions are seen as key drivers of employee engagement.demographic shifts also impact health plans and introduce demand for our services:


The proliferation of so many• In October 2020, CMS issued a final rule to increase price transparency among group health plans and health insurance issuers, requiring plans make available personalized, out-of-pocket healthcare costs in a self-service, internet-based tool, by January 1, 2023. We believe health plans may seek support from third-party services like ourselves in delivering the self-service tool required under this rule.

• Medicare Advantage (“MA”) enrollment continues to grow across both the Individual and wellbeing offerings has also ledGroup MA markets. According to another problem for employees: underutilization of the benefits actually provided to employees. A February 2016 surveyresearch conducted by the InternationalKaiser Family Foundation, approximately 24 million enrollees in 2020 were on an individual MA plan -- or 39% of Employee Benefit Plans found that only 19%the 62 million Medicare beneficiaries -- up from 24% of employers believe their employees have a high level of understanding their benefits. A March 2017 study by NBGH and Fidelity has shown utilization rates that are less than 20% for key benefits offerings like financial wellness, weight management, condition management, and resilience.total Medicare enrollees in 2010.


As a result ofBased on these factors,industry dynamics, we believe there is a significant long-term market opportunity for us to offerleverage our platform to help health plans manage healthcare costs through our digital and high tech solutions.

Market Opportunity. We consider the potential users of our products to be all individuals who receive health coverage through their employer or a technology-based solution that helps increase financialcommercial health plan. This includes individuals with employer-sponsored coverage, individuals purchasing coverage directly from a health plan or on an exchange, and management efficienciesindividuals participating in Medicare Advantage or Managed Medicaid programs administered by a commercial health plan. Based on the potential fee opportunity for employers in providing benefits, while improving employee benefit utilization.our current products, we estimate our total addressable market, including our digital navigation offering and Care Guides, is approximately $18 billion.

In October 2019, we entered into a 30-month enterprise license agreement with Anthem, effective January 1, 2020, that extends and expands our existing relationship first announced in 2015. The agreement includes our core care guidance technology, the Engage health navigation platform, and a new, non-exclusive license for some of our underlying health navigation platform technology services, such as transparency and personalization. With the 2019 agreement, Anthem moved from a channel partner for the Engage offering to a health plan customer.

As part of our COVID-19 response, in the fourth quarter of 2020, Castlight was engaged by Boston Children’s Hospital to support its work with the Centers for Disease Control and Prevention ("CDC") to manage inventory and data related to COVID-19 vaccines. We will deliver a vaccine provider platform, which allows providers to enroll, log, and report inventory, daily reporting for the CDC, and display of COVID-19 vaccine information on VaccineFinder.org, a project of Boston Children’s Hospital. The agreement with Boston Children's Hospital provides for payments to the Company totaling $8.5 million. We began the work in November 2020 and expect to complete the engagement in mid-2021.

Our Values. We operate under a set of core values that we believe capture who we are today as well as the future we are building together. Our values—One Team, On a Mission, Making Things Happen—are a consistent reminder of our mission and guide our day-to-day interactions:

One Team: We act from a place of respect and care for all and assume positive intent. We value communication and collaboration across teams. We consider how our actions impact others. We continue to build a diverse and inclusive community of Castlighters that energizes and inspires our work.
On a Mission: We exist to transform healthcare by empowering individuals to live healthier, happier lives. We create innovative, data-driven solutions to improve the wellbeing and healthcare journey of our users, including our employees. We address complex problems with pride, empathy, drive, and ownership.
Making Things Happen: We grow and adapt in partnership with our customers. We are nimble and take accountability for creating world-class experiences for our users.

Employee Feedback. As we keep our customers at the center of all we do, serving our employees and creating an environment for Castlighters to thrive is one of our top priorities. We are intentional about keeping our pulse on employee engagement by conducting regular surveys focused on workplace elements such as the employees’ continued effectiveness in a remote environment, access to the necessary resources to be successful in their roles, and gauging our employees’ productivity, health, and wellbeing. We intend to continue to reinforce and monitor the voice of our employees through our surveys and other communication vehicles we use, including regular employee all-hands, Teams and Slack communication platforms, virtual roundtables and check-ins. In addition to a dedicated management team and the HR team driving the employee engagement and communication efforts, we have an employee-driven Culture team engaged in designing and creating employee recognition, virtual engagement events, volunteering/giving, culture, and inclusion efforts.

Diversity, Inclusion, and Belonging. We believe we are a leader in diversity, inclusion, and sense of belonging, and seek to maintain our focus in these important areas for our workforce. As of December 31, 2020, women constitute 52% of our full-time workforce, 14% of our employees in the U.S. self-identified as a part of an under-represented minority group, and 40% of our employees at or above the Director level are women. Our talent acquisition program has led to steady, year-over-year increases in female and minority representation across Castlight, and we have established an annual hiring goal of 50% women and 20% individuals who identify as a member of an under-represented minority group. Our employees operate several Employee Resource Groups, including those for women in technology, LGBTQ-identified employees, and employee communities focused on interests such as cultural conversations and volunteering.

COVID-19. The COVID-19 pandemic caused us to modify certain in-person practices with employees, including curtailing employee travel, cancelling physical participation in internal and external meetings, events and conferences, and moving to fully remote work in March 2020. In June 2020, we implemented a return to office protocol for some employees located in our Utah Customer Center of Excellence, with what we believe to be a comprehensive protocol to ensure safety and wellbeing, including daily health screenings through our Working Well solution, physical changes to our floor layout, and required proper personal protection equipment. Our return to office plans for our San Francisco and Sunnyvale, California offices remain subject to local health orders and we have not yet been able to permanently re-open those offices.

Critically, as our workforce adjusted to the changing demands of the pandemic, we have continued to incorporate employee input and sentiment in our COVID-19 planning, and 86% of our employees who responded to our May 2020 employee engagement survey reported that they felt either “very supported” or “supported” by Castlight during COVID-19.

Strategic Relationships


Data Collaborations. We have existing relationships with many national and regional health plans, pharmacy benefit managers, (PBMs), dental insurers, behavioral health plans, and health savings plans to support our mutual customers. These collaborations provide us with claims, balance integrations, and other data on behalf of our employer customers. We have developed technologies in collaboration with several payers, including real-time integrated APIs. The increasing number of data integrations we have in place is helping to position usCastlight as a health navigation platform for our customers, and enables employers — and health plans — to consolidate many of their myriad sources of benefits information towardinto a single point of reference.

Intellectual Property


We rely on a combination of patent, trademark, copyright, and trade secret laws, as well as confidentiality procedures and contractual restrictions, to establish, maintain, and protect our proprietary rights. These laws, procedures, and restrictions provide only limited protection, and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed, or misappropriated. In addition, we may not be able to prevent others from developing technology that is similar to, but not the same as our proprietary technology. We generally require employees, consultants, customers, suppliers, and partners to execute confidentiality agreements with us that restrict the disclosure of our intellectual property. We also require our employees and consultants to execute invention assignment agreements with us that protect our intellectual property rights.

Requirements Regarding the Privacy and Security of Personal Information


U.S.-HIPAA and OtherU.S. Privacy and Security Requirements.There are many U.S. federal and state laws and regulations related to the privacy and security of personal health information. In particular,2019, California passed a privacy law, the California Consumer Privacy Act (“CCPA”), which gives California resident users significant rights over the use of their personal information, including the right to object to the “sale” of their personal information. In addition, the CCPA includes a private right of action related to security breaches. Less than one year after the CCPA became effective, California voters approved the California Privacy Rights Act (“CPRA”), a consumer privacy ballot initiative that amends and expands the CCPA. The CPRA affords California residents more control over their personal information, imposes heightened compliance requirements, and establishes a new enforcement agency dedicated to consumer privacy. The CPRA’s substantive provisions become effective January 1, 2023. Several other states are considering similar legislation, and new laws similar to CCPA, CPRS and GDPR (discussed below) are expected to be enacted in coming years in various jurisdictions in which we operate.

Additionally, regulations promulgated pursuant to the Health Insurance Portability and Accountability Act of 1996 and its implementing regulations, collectively HIPAA, establishes(collectively, "HIPAA"), establish privacy and security standards that limit the use and disclosure of protected health information ("PHI") and require the implementation of administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of individually identifiable health information in electronic form.

Our health plan customers, our direct enterprise customers’ benefits plans, as well as health care clearinghouses and certain providers with which we may have or may establish business relationships, are covered entities that are regulated under HIPAA. The Health Information Technology for Economic and Clinical Health Act or HITECH,("HITECH"), which became effective on February 17, 2010, significantly expanded HIPAA’s privacy and security requirements. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates,” whoassociates” are independent contractors or agents of covered entities thatwhich create, receive, maintain, or transmit protected health informationPHI in connection with providing a service for or on behalf of a covered entity.

Under HIPAA, and our contractual agreements with our customers, we are consideredCastlight serves as a “business associate” to our customers and thus areis directly subject to HIPAA’s privacy and security standards. In order to provide our covered entity customers with services that involve the use or disclosure of protected health information, HIPAA requires our customers to entertheir PHI, Castlight enters into business associate agreements with it. Such agreements must,our customers that require us to, among other things, require us to:things:

limit how we will use and disclose the protected health information;PHI;
implement reasonable administrative, physical, and technical safeguards to protect such informationPHI from misuse;
enter into similar agreements with our agents and subcontractors thatwho have access to the information;PHI;
report security incidents, breaches, and other inappropriate uses or disclosures of the information; and
assist the customer in question with certain duties under the privacy standards. 


                In addition to HIPAA regulations, we may be subject to other state and federal privacy laws, including laws that prohibit unfair or deceptive practices and laws that place specific requirements on use

Table of data. We cannot provide assurance regarding how the various privacy and security laws will be interpreted, enforced or applied to our operations.Contents

International Privacy Requirements.Requirements. In Europe, we are subject to the General Data Protection Regulation (“GDPR”) which replaced the 1995 European Union (“EU”) Directive on Data Protection (“1995 Data Protection Directive”), which requires EU member states to impose minimum restrictions on the collection and use of personal data that, in some respects, are more stringent, and impose more significant burdens on subject businesses, than current privacy standards in the United States. The EU member state regulations establish several obligations that organizations must follow with respect to use of personal data, including a prohibition on the transfer of personal information from the EU to other countries whose laws do not protect personal data to an adequate level of privacy or security. In addition, certain member states have adopted more stringent data protection standards. The Company has addressed these requirements by certification to the EU/US Privacy Shield framework the European Commission deemed the EU-U.S. Privacy Shield Framework adequate to enable data transfers under EU law July 12, 2016. On January 12, 2017, the Swiss Government announced the approval of the Swiss-U.S. Privacy Shield Framework as a valid legal mechanism to comply with Swiss requirements when transferring personal data from Switzerland to the United States.

On December 15, 2015, the European Parliament and the Council of the European Union (Council) reached a political agreement on the future EU data protection legal framework. Formally adopted by the European Parliament in 2016, the General Data Protection Regulation (“GDPR”) replaced the 1995 Data Protection Directive. GDPR will be effective in May 2018. GDPR includes operational requirements for companies that receive or process personal data of European Union residents, that are different than those currently in place in the European Union, and that will includeincludes significant penalties for non-compliance. In addition, some countries are considering or have passed legislation implementing data protection requirements or requiring local storage and processing of data, or similar requirements that could increase the cost and complexity of delivering our services. In Canada, we are subject to Canada’s Personal Information Protection and Electronic Documents Act ("PIPEDA"). PIPEDA, as well as province-specific regulations, imposes specific obligations on includes requirements for companies that receive personal information for Canadian residents, and includes penalties for non-compliance.

Data Protection and Breaches.Breaches. In recent years, there have been a number of well-publicized data breaches involving the improper use and disclosure of individuals’ personal information. Many states have responded to these incidents by enacting laws requiring holders of personal information to maintain safeguards and to take certain actions in response to a data breach, such as providing prompt notification of the breach to affected individuals and state officials. In addition, under HIPAA, we must report breaches of unsecured protected health informationPHI to our contractual partners, within 60 daysto the Department of discovery of the breach. Notification must also be made to HHSHealth and Human Services, and, in certain circumstances involving large breaches, to the media. Under the GDPR, the data controller is required to report personal data breaches to the supervisory authority within 72 hours of discovery of the breach.


We have implemented and maintained physical, technical and administrative safeguards intended to protect all personal data, and have processes in place to assist it in complying with all applicable laws, regulations and contractual requirements regarding the protection of these data and properly responding to any security breaches or incidents. However, we cannot be sure that these safeguards are adequate to protect all personal data or to assist us in complying with all applicable laws and regulations regarding the privacy and security of personal data and responding to any security breaches or incidents. Furthermore, in many cases, applicable state laws, including breach notification requirements, are not preempted by the HIPAA privacy and security standards and are subject to interpretation by various courts and other governmental authorities, thereby complicating our compliance efforts. Additionally, state and federal laws regarding deceptive practices may apply to public assurances we give to individuals about the security of services we provide on behalf of our contractual customers.

Other Requirements. In addition to HIPAA, numerous other U.S. state and federal laws govern the collection, dissemination, use, access to, and confidentiality of personally identifiable information, individually identifiable health information, and health care provider information. Some states also are consideringhave implemented new laws and regulations that further protect the confidentiality, privacy, and security of medical records or other types of medicalsuch information. In many cases, these state laws are not preempted by the HIPAA privacy standards and may be subject to interpretation by various courts and other governmental authorities. Further, Congress and a number of states have considered or are considering prohibitions or limitations on the disclosure of medical or other information to individuals or entities located outside of the United States.


We dedicate significant resources to protecting our customers’ and users' information, including confidential and protected health information, or PHI. Our security strategy employs various practices and technology to control and protect access to sensitive information. In 2016, our Jiff product received certification status from

Our growth depends in part on the success of our strategic relationships with third parties.
We operate in a competitive industry. If we are not able to compete effectively, our business and operating results will be harmed.
Our business depends, in part, on sales, direct or indirect, to government organizations, and significant changes in the contracting or fiscal policies of such government organizations could have an adverse effect on our business and operating results.
Our proprietary software may not operate properly, which could damage our reputation, give rise to claims against us or divert application of our resources from other purposes, any of which could harm our business and operating results.
Any failure by us to offer high-quality technical support services may adversely affect our relationships with our customers and harm our reputation and financial results.
If we cannot implement our offerings for customers in a timely manner, we may lose customers and our reputation and financial results may be harmed.
Our marketing efforts depend significantly on our ability to receive positive references from our existing customers.
If our security measures are breached and customers' data are compromised, our offerings may be perceived as insecure, we may incur significant liabilities, our reputation may be harmed and we could lose sales and customers.
We have a history of significant GAAP losses, which we expect to continue for the foreseeable future, and we may never achieve or sustain profitability in the future.
The market for our offerings is immature and volatile, and if it does not further develop, if it develops more slowly than we expect, or if our offerings do not drive employee engagement, the growth of our business will be harmed.
We incur significant upfront costs in our customer relationships, and if we are unable to maintain and grow these customer relationships over time, we are likely to fail to recover these costs and our operating results will suffer.
Our ability to deliver our full offerings to customers depends in substantial part on our ability to access data and other resources that are managed by a limited number of health plans and other third parties.
A significant portion of our revenue comes from a limited number of customers, the loss of which would adversely affect our financial results.
Because we generally bill our customers and recognize revenue over the term of the contract, near term declines in new or renewed agreements may not be reflected immediately in our operating results and may be difficult to discern.
Our sales and implementation cycle can be long and unpredictable and require considerable time and expense, which may cause our operating results to fluctuate.
The health care industry is heavily regulated. Our failure to comply with regulatory requirements could create liability for us, result in adverse publicity and otherwise negatively affect our business.
If we fail to comply with applicable health information privacy and security laws and other applicable state, federal and international privacy and security laws, we may be subject to significant liabilities, reputational harm and other negative consequences, including decreasing the willingness of current and potential customers to work with us.
Shifts in health care benefits trends, including any potential decline in the number of self-insured employers, or the emergence of new technologies, may render our offerings obsolete or require us to expend significant resources in order to remain competitive.
We may require additional capital to support business growth, and this capital might not be available to us on acceptable terms, or at all.
We depend on data centers operated by third parties for our offerings, and any disruption in the operation of these facilities could adversely affect our business.
The information that we provide to our customers, and their employees and families, could be inaccurate or incomplete, which could harm our business, financial condition and results of operations.
If we cannot maintain our corporate culture as we grow, we could lose the elements of our culture that we believe contribute to our success and, as a result, our business may be harmed.
If we fail to develop widespread brand awareness cost-effectively, our business may suffer.
Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

We rely on channel partnersAnthem for a substantial portion of our sales, and if our channel partner relationships are unsuccessful then our sales results will be adversely affected and the growthrevenue.

Table of our business will be harmed.Contents


Our sales strategy relies in part on relationships we have developed with Anthem, Inc. ("Anthem") as well as relationships we have built or are working to build with other health plans, benefits consultants, brokersincluding Cigna Corporation and Blue Cross Blue Shield Alabama. In October 2019, we entered into new agreements with Anthem whereby various services previously provided to Anthem’s customers on a disaggregated basis under separate service order forms were consolidated under a Software-as-a-Service Agreement (the “SaaS Agreement”).Under the SaaS Agreement, Anthem is committed to paying us significant annual license fees for calendar years 2020 and 2021 and the first six months of 2022, which is likely to constitute a substantial amount of our revenue for such periods. Revenue from Anthem, under our agreement, constituted approximately 47% of our total revenue for the year ended December 31, 2020. If the SaaS Agreement were to be terminated by Anthem under its terms, or if Anthem breaches the terms of the SaaS Agreement, our business would be materially harmed.

While our current growth strategy includes investing resources in pursuing relationships with other industry participants, andhealth plans to leverage what we are continuing to invest in, and expect to continue to increase our reliance on,have experienced with Anthem, developing these relationships with channel partners to access customerswill take time, require significant upfront investment, and growdivert our overall sales. However, there can be no assurance that our channel partner relationships will be successful, or will result in access to additional customers or growth in sales. Our channel partnerships don’t always meet our expectations and could fail for a variety of reasons, including changes in our partners’ business priorities, insufficient or misaligned incentives for our partners’ to assist us with sales, competition, orattention from other factors. 

opportunities. In addition, our reliance on sales through channel partners could put downward pressure on the total revenue we are able to generate, and could result in existing customers electing to use alternative or lower-functionality versions of our products that we may elect to provide through channel partners. The concentration of a material portion of business with any given channel partner such as Anthem could also create tensions with other companies with which we do business, with, including health plans on whomupon which we rely to receive data and offer our services.

CertainIf we are unable to successfully enter into new business relationships we will enter or have entered into with channel partners will require substantial investments ofand diversify our resources to support these initiatives.  There can be no assurance that the investments we make to develop and support these channel relationships, or the effort required to do so, will provide a positive return on our investment in the near term, or at all.  If any of these events materialize,revenue stream, our business and results of operations couldwould be materially adversely affected.

If our new products and services are not adopted by our customers, or if we fail to continue to innovate and develop new products and services that are adopted by customers, then our revenue and operating results will be adversely affected.
Prior to our acquisition of Jiff,
In prior years, we derived a substantial majority of our revenue from sales of our legacy care guidance platform, and our longer-term operating results and continued growth depend depends in part on our ability to successfully develop and sell new products and services that ourto new and existing customers want and are willing to purchase. In addition to our legacy core Castlight platform (now marketed as our care guidance solution), wecustomers. We continue to introduce a number of products and cross-sells, such as our latest offeringrecent offerings of Castlight Complete, Care Guidance Navigator, Wellbeing ElevateNavigator, Castlight Care Guides and Engage, but it is uncertain whether these products and services will result in significant revenue or comprise a significant portion of our total revenue. In addition, based on our belief that our customers are interested in acquiring wellness-related products, we have devoted substantial efforts to our acquisition of Jiff, and expect to continue to devote substantial efforts to the integration and expansion of the Jiff business.Working Well, as well as health plan solutions. We have also invested, and will continue to invest, significant resources in research and development to enhance our existing offeringofferings and introduce new high qualityhigh-quality products and services. If existing customers are not willing to make additional payments for such new products, or if new customers do not value such new products, our business and operating results will be harmed. If we are unable to predict useremployer preferences or our industry changes, or if we are unable to modify our offeringofferings and services on a timely basis, we might lose customers. Our operating results would also suffer if our innovations are not responsive to the needs of our customers, appropriately timed with market opportunity or effectively communicated and brought to market.
If our existing customers, including health plan customers, do not continue or renew their agreements with us, renew at lower fee levels or decline to purchase additional products and services from us, our business and operating results will suffer.be harmed.
We expect to derive a significant portion of our revenue from renewal of existing customer agreements, including existing and future agreements with health plan customers or prospective customers, and sales of additional products and services to existing customers. Revenue recognized in any quarter is largely derived from customer agreements signed in prior quarters. As a result, achieving a high renewal rate of our customer agreements and selling additional products and services is critical to our future operating results.

Factors that may affect the renewal rate for our offering,offerings, terms of those renewals, and our ability to sell additional products and services include:

changes in health care laws, regulations or trends; and
the business environment of our customers, in particular, headcount reductions by our customers.customers (which may be further implicated by the current COVID-19 pandemic), which affect subscription fees we are able to bill for.


We enter into master services agreements with our customers. These agreements generally have stated terms of three years. Our customers have no obligation to renew their subscriptions for our offeringofferings after the term expires. In addition, our customers may negotiate terms less advantageous to us upon renewal, which may reduce our revenue from these customers. Factors that are not within our control may contribute to a reduction in our contract revenue. For instance, our customers may reduce their number of employees, which would result in a corresponding reduction in the number of employee users eligible for our offeringofferings and thus a lower aggregate monthly services fee. Our future operating results also depend, in part, on our ability to sell new products and services to our existing customers. If our direct or indirect customers fail to renew their agreements, renew their agreements upon less favorable terms or at lower fee levels, or faildecline to purchase new products and services from us, our revenue may decline or our future revenue may be constrained.
    
In addition, a significant number of our customer agreements allow customers to terminate such agreements for convenience at certain times, typically with one to three months advance notice. We typically incur the expenses associated with integrating a customer’s data into our health care database and related training and support prior to recognizing meaningful revenue from such customer. Customer subscription revenue is not recognized until our products are implemented for launch, which is generally from three to 12 months from contract signing. If a customer terminates its agreement early and revenue and cash flows expected from a customer are not realized in the time period expected or not realized at all, our business, operating results and financial condition could be adversely affected.

Our growth depends in part on the success of our strategic relationships with third parties.

In order to grow our business, we anticipate that we will continue to depend on our relationships with third parties. Apart from health plan customers or potential customers, channel partners such as benefit consultants and data partners, our offerings also include the integration of products supplied by strategic partners who offer complementary products and services. We rely on these strategic partners to timely and successful deploy our offerings to our customers. If the products provided by these partners have defects or do not operate as expected, the services provided by these partners are not completed in a timely manner, our partners have organizational or supply issues, or we do not effectively integrate and support products supplied by these strategic partners, we may have difficulty deploying our offerings which could result in loss of, or delay in, revenues, increased service and support costs, and a diversion of development resources. In addition, our reliance on sales through, or facilitated by, third parties could put downward pressure on the total revenue we are able to generate, and could result in existing customers electing to use alternative or lower-functionality versions of our products that we may elect to provide through such relationships.

We also may compete in some areas with these same strategic partners. If these strategic partners fail to perform or choose not to cooperate with us on certain projects, in addition to the effects described above, we could experience loss of customers and market share, and failure to attract new customers or achieve and maintain market acceptance for our products. Identifying partners, negotiating and documenting relationships, and building integrations with them requires significant time and resources. If we are unsuccessful in establishing or maintaining our relationships with third parties, our ability to compete in the marketplace or to grow our revenue could be impaired and our operating results may suffer. Even if we are successful, we can provide no assurance that these relationships will result in increased customer use of our platform or increased revenue.
We operate in a competitive industry, and ifindustry. If we are not able to compete effectively, our business and operating results will be harmed.
    
The health navigation market for our productsis evolving and services ishighly competitive. We face competitive and we expect the market to attract increased competition, which could make it hard for us to succeed. We currently face competition for portions of our offeringpressure from a rangenumber of companies, including healthcare information technology companies and specialized software and solution providers that offer similar solutions, often at substantially lower prices, and that are continuing to develop additional products and becoming more sophisticated and effective. Our market is in an early stage of development, but is rapidly evolving and competitive. We currently face competition from both existing and emerging vendors across a variety oftraditional digital health categories, fromas specialists in thenavigation, wellbeing, concierge, care guidance, and wellbeing areas of the market,member engagement converge to broader offerings that compete within this market.

Wellbeing competitors include: Limeade, Redbrick Health, VirginPulse, and Vitality. Platform competitors include Evive, HealthAdvocate,Sharecare, Welltok, and Sharecare.Vitality.

In addition, large, well-financed health plans, with whom we cooperate and on whom we depend in order to obtain the pricing and claims data we need to deliver our offeringofferings to customers, have in some cases developed or acquired their own wellbeing and care guidance tools and provide these solutions to their customers at discounted prices or often for free. These health plans include, for example, Aetna Inc., Cigna Corporation, Anthem, Inc., and UnitedHealth Group, IncInc. (Rally and Health Care Services Corporation.Corporation). Competition from specialized software and solution providers, health plans and other parties may result in pricing pressure, which may lead

to price decline in certain product segments, which could negatively impact our sales, profitability and market share. In addition, if health plans perceive continued cooperation with us as a threat to their business interests, they may take steps that impair our access to pricing and claims data, or that otherwise make it more difficult or costly for us to deliver our offeringofferings to customers.


Some of our competitors, in particular health plans, have greater name recognition, longer operating histories, and significantly greater resources than we do. Furthermore, our current or potential competitors may be acquired by third parties with greater available resources. As a result, our competitors might be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards or customer requirements and may have the ability to initiate or withstand substantial price competition. In addition, current and potential competitors have established, and mightmay in the future establish, cooperative relationships with vendors of complementary products, technologies or services to increase the availability of their solutions in the marketplace.

The field of healthcare and thehealthcare related services related to healthcare areis subject to change, and there has been consolidation in the industry. Accordingly, new competitors or alliances might emerge that have greater market share, a larger customer base, more widely adopted proprietary technologies, greater marketing expertise, greater financial resources, and larger sales forces than we have, which could put us at a competitive disadvantage. Our competitors could also be better positioned to serve certain segments of our market, such as customers that desire a more narrownarrower solution, which could create additional price pressure. In light of these factors, even if our offering isofferings are more effective than those of our competitors, current or potential customers might accept competitive offerings in lieu of purchasing our offerings.
Our business depends, in part, on sales, direct or indirect, to government organizations, and significant changes in the contracting or fiscal policies of such government organizations could have an adverse effect on our business and operating results.

Wecurrently deriveaportionofourrevenuefrom a subcontract with Boston Children’s Hospital under its master contract with the Centers for Disease Control and Prevention, a U.S. government agency, and we may seek opportunities to contract, directly or indirectly, with additional public sector customers in the future. However, demand from government organizations is often unpredictable, and we cannot assure you that we will be able to maintain or grow our revenue from the public sector. Sales to government entities are subject to substantial risks, including, but not limited to, the following:

highly competitive, expensive, and time-consuming sales cycles that often require significant upfront time and financial investment without any assurance of success;
U.S. or other government certification requirements applicable to our platform, including the Federal Risk and Authorization Management Program, are often difficult and costly to obtain and maintain, and failure to do so will restrict our ability to sell to government customers;
impacts on government demand and payment for our services by changes in administration, public sector budgetary cycles, and funding authorizations; and
routine investigations and audits by governments of its contractors’ administrative processes and any unfavorable results of such investigations or audits that may result in fines, civil or criminal liability, further investigations, damage to our reputation, or debarment from further government business.

The occurrence of any of the foregoing factors could cause governments and governmental agencies to delay or refrain from purchasing our services in the future or otherwise have an adverse effect on our business and operating results. In addition, our current subcontract with Boston Children’s Hospital is specific to the COVID-19 pandemic, and will not continue once the pandemic is mitigated.

Our proprietary software may not operate properly, which could damage our reputation, give rise to claims against us or divert application of our resources from other purposes, any of which could harm our business and operating results.

Proprietary software development is time-consuming, expensive and complex, and may involve unforeseen difficulties. We may encounter technical obstacles, and it is possible that we will discover additional problemsissues that prevent our proprietary products from operating properly. We are currently developing new features and services in our proprietary software includingfor all of our Complete Health, Wellbeing, Care Guidance, Elevate and Engage.offerings. If any of our offering does notofferings fail to function reliably or failsfail to achieve customer expectations in terms of performance, customers could assert liability claims against us or attempt to cancel their contracts with us. This could damage our reputation and impair our ability to attract or maintain clients which would adversely affect our operating resultsresults.

    
Moreover, data services that are as complex as those we offer have in the past contained, and may in the future develop or contain, undetected defects or errors. This includes products we develop ourselves, as well as those we integrate into our platform ecosystem and resell. Material performance problems, defects or errors in our existing or new software and products and services may arise in the future and may result from interface of our offeringofferings with systems and data that we did not develop and the function of which is outside of our control or undetected in our testing. These defects and errors, and any failure by us to identify and address them, could result in loss of revenue or market share, diversion of development resources, injury to our reputation and increased service and maintenance costs. Defects or errors in our health benefitsnavigation platform might discourage existing or potential customers from purchasing our offeringofferings from us. Correction of defects or errors could prove to be impossible or impracticable. The costs incurred in correcting any defects or errors may be substantial and could adversely affect our operating results.
Any failure by us to offer high-quality technical support services may adversely affect our relationships with our customers and harm our reputation and financial results.
Our customers depend on our support organization to resolve any technical issues relating to our offering.offerings. In addition, our sales process is highly dependent on the quality of our offering,offerings, our business reputation and on strong recommendations from our existing customers. Any failure to maintain high-quality and highly-responsive technical support, or a market perception that we do not maintain high-quality and highly-responsive support, couldwould harm our reputation, adversely affect our ability to sell our offeringofferings to existing and prospective customers, and harm our business, operating results and financial condition.

We offer technical support services with our offeringofferings and may be unable to respond quickly enough to accommodate short-term increases in customer demand for support services, particularly as we increase the size of our customer base. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. It is difficult to predict customer demand for technical support services and if customer demand increases significantly, we may be unable to provide satisfactory support services to our customers and their employees. Additionally, increased customer demand for these services, without corresponding revenue, could increase costs and adversely affect our operating results.
If we cannot implement our offeringofferings for customers in a timely manner, we may lose customers and our reputation and financial results may be harmed.
Our customers have a variety of different data formats, enterprise applications and infrastructure and our offeringofferings must support our customers’ data formats and integrate with complex enterprise applications and infrastructures. If our platform does not currently support a customer’s required data format or appropriately integrate with a customer’s applications and infrastructure, or if an existing customer switches to unsupported infrastructure, then we mustmay have to configure our platform to do so, which increases our expenses. Additionally, we do not control our customers’ implementation schedules. As a result, if our customers do not allocate internal resources necessary to meet their implementation responsibilities or if we face unanticipated implementation difficulties, the implementation may be delayed. Further, our implementation capacity has at times constrained our ability to successfully implement our offeringofferings for our customers in a timely manner, particularly during periods of high demand. If the customer implementation process is not executed successfully or if execution is delayed, we could incur significant costs, customers could become dissatisfied and decide not to increase usage of our offering,offerings, or not to use our offeringofferings beyond an initial period prior to their term commitment or, in some cases, revenue recognition could be delayed. Our data dependencies and implementation procedures differ for each new product that we launch. Accordingly, our ability to convert sales of new products into billings and revenue depends on our ability to create a scalable launch infrastructure in each case. In addition, competitors with more efficient operating models withand lower implementation costs could penetrate our customer relationships.

Additionally, large and demanding enterprise customers, who currently comprise the majority of our customer base, may request or require specific features or functions unique to their particular business processes, which increase our upfront investment in sales and deployment efforts and the revenue resulting from the customers under our typical contract length may not cover the upfront investments. If prospective large customers require specific features or functions that we do not offer, then the market for our offeringofferings will be more limited and our business could suffer.


In addition, supporting large customers could require us to devote significant development services and support personnel and strain our personnel resources and infrastructure. Furthermore, if we are unable to address the needs of these customers in a timely fashion or further develop and enhance our offering,offerings, or if a customer or its employees are not satisfied with our quality of work, our offeringofferings or professional services then we could incur additional costs to address the situation. In addition, we may be required to issue credits or refunds for prepaid amounts related to unused services, the timing of recognition of revenue for, and the profitability of, that work might be impaired and the customer’s dissatisfaction with our offeringofferings could damage our ability to expand the number of products and services purchased by that customer. These customers may not renew their agreements, seek to terminate their relationship with us or renew on less favorable terms. Moreover, negative publicity related to our customer relationships, regardless of its accuracy, may further damage our business by affecting our ability to retain or compete for new business with current and prospective customers. If any of these were to occur, our revenue may fail to grow at historical rates or at all, or may even decline, and our operating results could be adversely affected.
If we fail to manage our growth effectively, our expenses could increase more than expected, our revenue may not increase and we may be unable to implement our business strategy.
We have experienced significant growth in recent periods, which puts strain on our business, operations and employees. For example, our revenue has increased from $101.7 million for the year ended December 31, 2016 to $131.4 million for the year ended December 31, 2017. Future revenues may not grow at these same rates or may decline. To manage our current and anticipated future growth effectively, we must continue to maintain and enhance our IT infrastructure, financial and accounting systems and controls. Moreover, we may from time to time decide to undertake cost savings initiatives, such as the reduction in workforce we implemented in 2016, or disposing of, or otherwise discontinuing certain products, in an effort to focus our resources on key strategic initiatives and streamline our business. We must also attract, train and retain a significant number of

qualified personnel in key areas such as research and development, sales and marketing, customer support, professional services, and management, and the availability of such personnel, in particular software engineers, may be constrained. These and similar challenges, and the related costs, may be exacerbated by the fact that our headquarters are located in the San Francisco Bay Area.
A key aspect to managing our growth is our ability to scale our capabilities to implement our offering satisfactorily with respect to both large and demanding enterprise customers, who currently comprise the substantial majority of our customer base, as well as smaller customers. Large customers often require specific features or functions unique to their particular business processes, which at a time of rapid growth or during periods of high demand, may strain our implementation capacity and hinder our ability to successfully implement our offering to our customers in a timely manner. We may also need to make further investments in our technology and automate portions of our offering or services to decrease our costs, particularly as we grow sales of our health benefits platform to smaller customers. If we are unable to address the needs of our customers or their employees, or our customers or their employees are unsatisfied with the quality of our offering or services, they may not renew their agreements, seek to cancel or terminate their relationship with us or renew on less favorable terms. In addition, many of our customers adjust their benefit plan designs, benefits providers and eligibility criteria at the start of each new benefits plan year, requiring additional configurations for those customers. As our customer base grows, the complexity of these activities can increase. If we fail to automate these operations sufficiently and implement these changes on a timely basis or are unable to implement them effectively, our business may suffer.

We may experience additional challenges with managing our growth relating to our acquisition of Jiff. We expect that the operation and integration of the Jiff business will require substantial financial costs and substantial management attention. If we fail to effectively manage the integration process, our business and financial results may suffer.
Failure to effectively manage our growth could also lead us to over-invest or under-invest in development and operations, result in weaknesses in our infrastructure, systems or controls, give rise to operational mistakes, financial losses, loss of productivity or business opportunities and result in loss of employees and reduced productivity of remaining employees. Our growth is expected to require significant capital expenditures and might divert financial resources from other projects such as the development of new products and services. In addition, data and content fees, which are one of our primary operational costs, are not fixed as they vary based on the source and condition of the data we receive from third parties, and if they remain variable or increase over time, we would not be able to realize the economies of scale that we expect as we grow renewals and implementation of new customers, which would negatively impact our gross margin. If our management is unable to effectively manage our growth, our expenses might increase more than expected, our revenue may not increase or might grow more slowly than expected and we might be unable to implement our business strategy. The quality of our offering might also suffer, which could negatively affect our reputation and harm our ability to retain and attract customers.
We depend on our senior management team, and the loss of one or more of our executive officers or key employees or an inability to attract and retain highly skilled employees or key subcontractor services could adversely affect our business.
Our success depends largely upon the continued services of our key executive officers. These executive officers are at-will employees and therefore may terminate employment with us at any time with no advance notice. We do not maintain “key person” insurance for any of these executive officers or any of our other key employees. We also rely on our leadership team in the areas of research and development, marketing, services and general and administrative functions. From time to time, there may be changes in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. The replacement of one or more of our executive officers or other key employees would likely involve significant time and costs and may significantly delay or prevent the achievement of our business objectives.

To continue to execute our growth strategy, we also must attract and retain highly skilled personnel, particularly in research and development and sales and marketing. Competition is intense for engineers with high levels of experience in designing and developing software and Internet-related services, particularly in the San Francisco Bay Area where we are located. We might not be successful in maintaining our unique culture and continuing to attract and retain qualified personnel. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled personnel with appropriate qualifications. The pool of qualified personnel with Software-as-a-Service, or SaaS, experience or experience working with the health care market is limited overall. In addition, many of the companies with which we compete for experienced personnel have greater resources than we have. We supplement our hired skilled personnel through the use of subcontractors, particularly in the area of research and development, a significant portion of which perform services outside of the United States. If these subcontractors cease to perform services for us for any reason,

our ability to meet our development goals may be impaired, and our business and future growth prospects could be severely harmed.
In addition, in making employment decisions, particularly in the Internet and high-technology industries, job candidates often consider the value of the stock options or other equity instruments they are to receive in connection with their employment. Volatility or performance trends in the price of our stock might, therefore, adversely affect our ability to attract or retain highly skilled personnel. Furthermore, the requirement to expense stock options and other equity instruments might discourage us from granting the size or type of stock option or equity awards that job candidates require to join our company. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects could be severely harmed.
Our marketing efforts depend significantly on our ability to receive positive references from our existing customers.
Our marketing efforts depend significantly on our ability to call on our current customers to provide positive references to new, potential customers. Given our limited number of long-term customers, the loss or dissatisfaction of any customer could substantially harm our brand and reputation, inhibit the market adoption of our offeringofferings and impair our ability to attract new customers and maintain existing customers. Any of these consequences could have a material adverse effect on our business, financial condition and results of operations.
If our security measures are breached and unauthorized access to a customer’scustomers' data are obtained,compromised, our offeringofferings may be perceived as insecure, we may incur significant liabilities, our reputation may be harmed and we could lose sales and customers.
Our offering involvesofferings involve the storage and transmission of customers’ proprietary information, personally identifiable information, and protected health informationPHI of our customers’ employees and their dependents, which is regulated under the Health Insurance Portability and Accountability Act of 1996 and its implementing regulations, collectively HIPAA. Because of the extreme sensitivity of this information, the security features of our offeringofferings are very important. If our security measures, some of which are managed by third parties, are breached or fail, unauthorized persons may be able to obtain access to sensitive customer or employee data, including HIPAA-regulated protected health information.PHI. A security breach or failure could result from a variety of circumstances and events, including third-party action, employee negligence or error, malfeasance, computer viruses, attacks by computer hackers, failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, telecommunication failures, user errors, and catastrophic events. Additionally, many of our employees transitioned to remote working arrangements as a result of the COVID-19 pandemic, which has amplified our reliance on computer systems and on our continued need for unimpeded access to the Internet to use those systems. An extended period of remote work arrangements could strain our business continuity plans, introduce operational risk, including but not limited to cybersecurity risks, and impair our ability to manage our business.


If our security measures were to be breached or fail, our reputation could be severely damaged, adversely affecting customer or investor confidence, customers may curtail their use of or stop using our offeringofferings and our business may suffer. In addition, we could face litigation, damages for contract breach, penalties and regulatory actions for violation of HIPAA and other laws or regulations applicable to data protection and significant costs for remediation and for measures to prevent future occurrences. In addition, any potential security breach could result in increased costs associated with liability for stolen assets or information, repairing system damage that may have been caused by such breaches, incentives offered to customers or other business partners in an effort to maintain the business relationships after a breach and implementing measures to prevent future occurrences, including organizational changes, deploying additional personnel and protection technologies, training employees and engaging third-party experts and consultants. While we maintain insurance covering certain security and privacy damages and claim expenses, we may not carry insurance or maintain coverage sufficient to compensate for all liability and such insurance may not be available for renewal on acceptable terms or at all, and in any event, insurance coverage would not address the reputational damage that could result from a security incident.

We outsource important aspects of the storage and transmission of customer information, and thus rely on third parties to manage functions that have material cyber-security risks. These outsourced functions include services such as software design and product development, software engineering, database consulting, call center operations, co-location data centers, data-center security, IT, network security and Web application firewall services. We attempt to address these risks by requiring outsourcing subcontractors who handle customer information to sign business associate agreements contractually requiring those subcontractors to adequately safeguard personal health data and in some cases by requiring such outsourcing subcontractors to undergo third-party security examinations. However, we cannot assure you that these contractual measures and other safeguards will adequately protect us from the risks associated with the storage and transmission of customers proprietary and protected health information.PHI.

We may experience cyber-security and other breach incidents that may remain undetected for an extended period. Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against us, we may be unable to anticipate these techniques or to implement adequate preventive measures. In addition, in the event that our customers authorize or enable third parties to access their data or the data of their employees on our systems, we cannot ensure the complete integrity or security of such data in our systems as we would not control that access. Third parties may also attempt to fraudulently induce our employees or customers and their employees into disclosing sensitive information such as user names, passwords or other information or otherwise compromise our security measures in order to gain access to customer information, which could result in significant legal and financial exposure, a loss of confidence in the security of our offering,offerings, interruptions or malfunctions in our operations, and, ultimately, harm to our future business prospects and revenue. Because our offering offersofferings offer single sign-on capabilities for our customers and their employees to point solutions offered by our partners, unauthorized access to our offeringofferings could also result in security breaches of customer information and data in offerings by our partners. We may be required to expend significant capital and financial resources to invest in security measures, protect against such threats or to alleviate problems caused by breaches in security. If an actual or perceived breach of our security occurs, or if we are unable to effectively resolve such breaches in a timely manner, the market perception of the effectiveness of our security measures could be harmed and we could lose sales and customers or suffer other reputational harm.
Regardless of the merits of any such suit, defending it could be costly and divert management’s attention from leading our business.
We have a history of significant GAAP losses, which we expect to continue for the foreseeable future, and we may never achieve or sustain profitability in the future.
We have incurred significant GAAP net losses in each year since our incorporation in 2008 and currently expect to continue to incur GAAP net losses for at least fiscal 2018.2021. We experienced GAAP net losses of $55.6$62.2 million $58.5(inclusive of a non-cash goodwill impairment charge of $50.3 million during the first quarter of 2020), $40.0 million and $79.9$39.7 million during the years ended December 31, 2017, 20162020, 2019 and 2015,2018, respectively. As of December 31, 2017,2020, we had an accumulated deficit of $411.6$517.2 million. The GAAP losses and accumulated deficit were primarily due to the substantial investments we made to grow our business, enhance our technology and offeringofferings through research and development and acquire and support customers. We anticipate that cost of revenue and operating expenses will increase in the foreseeable future as we seek to continue to grow our business, enhance our offering and acquire customers. In addition, as a result of our acquisition of Jiff, we have incurred substantial transaction costs and expect to incur further increases in our cost of revenue and operating expenses in connection with the integration of the Jiff and Castlight functionalities and costs to acquire customers. These efforts may prove more expensive than we currently anticipate, and we may not succeed in increasing our revenue sufficiently to offset these higher expenses. Many of our efforts to generate revenue from our business are new and unproven to us, and any failure to increase our revenue or generate revenue from new products and services could prevent us from achieving or maintaining profitability. Furthermore, to the extent we are successful in increasing our customer base, we could also incur increased GAAP losses because costs associated with entering into customer agreements are generally incurred up front, while customers are generally billed over the term of the agreement. Our prior GAAP losses, combined with our expected future GAAP losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital. We expect to continue to incur GAAP operating losses for the foreseeable future and may never become profitable on a quarterly or annual basis, or if we do, we may not be able to sustain profitability in subsequent periods. As a result of these factors, we may need to raise additional capital through debt or equity financings in order to fund our operations, which could be dilutive to stockholders, and such capital may not be available on reasonable terms, ifor at all.
Our limited operating history makes it difficult to evaluate our current business and future prospects.
We were founded in 2008, began building the first version of our care guidance platform in 2009, did not complete our first customer sale and implementation until 2010 and did not make substantial investments in sales and marketing until 2012. Jiff was founded in 2010 and had its first customer implementation in 2013 before being acquired by us in April of 2017. The limited operating histories of these two businesses, standalone and as combined, limit our ability to forecast our future operating results and such forecasts are subject to a number of uncertainties, including our ability to plan for and model future growth.
We have encountered and will continue to encounter risks and uncertainties frequently experienced by new and growing companies in rapidly changing industries, such as determining appropriate investments of our limited resources, market adoption of our existing and future offerings, competition from other companies, acquiring and retaining customers, managing customer deployments, hiring, integrating, training and retaining skilled personnel, developing new products and

17

Table of Contents



services, determining prices for our products, handling unforeseen expenses and managing challenges in forecasting accuracy. If our assumptions regarding these and other similar risks and uncertainties, which we use to plan our business, are incorrect or change as we gain more experience operating our business or due to changes in our industry, or if we do not address these risks and uncertainties successfully, our operating and financial results could differ materially from our expectations and our business could suffer.

In addition, we may need to change our current operations infrastructure in order for us to achieve profitability and scale our operations efficiently, which makes our future prospects even more difficult to evaluate. For example, in order to grow sales of our health benefits platform to smaller customers in a financially sustainable manner, we may need to further automate implementations, tailor our offering and modify our go-to-market approaches to reduce our service delivery and customer acquisition costs. If we fail to implement these changes on a timely basis or are unable to implement them effectively, our business may suffer.

Following our acquisition of Jiff, we may be unable to integrate successfully the businesses of Castlight and Jiff and realize the anticipated benefits of the transaction.

Following the acquisition, as a combined company we have been and will continue to be required to devote significant management attention and resources to integrating the business practices and operations of the two businesses. As a combined company, we may fail to realize some or all of the anticipated benefits of the acquisition if the integration process takes longer than expected or is more costly than expected. As a combined company we may encounter difficulties in the integration process that include the following:

the inability to successfully combine the businesses of Castlight and Jiff in a manner that permits the combined company to achieve the synergies anticipated to result from the acquisition, which would result in the anticipated benefits of the acquisition not being realized partly or wholly in the time frame currently anticipated or at all;
lost sales and customers as a result of certain customers of either of the two companies deciding not to do business with the combined company;
complexities associated with managing the combined businesses;
integrating personnel from the two companies;
creating uniform standards, controls, procedures, policies and information systems;
performance shortfalls at one or both of the two companies as a result of the diversion of management’s attention caused by integrating the companies’ operations and functionality, or developing new functionality; and
potential loss of brand awareness or confusion as a result of our re-branding activities.

It is possible that the integration process could result in the diversion of management’s attention, the disruption or interruption of, or the loss of momentum in, the ongoing business or inconsistencies in standards, controls, procedures and policies, any of which could adversely affect our ability as a combined company to maintain relationships with customers, partners and employees or its ability to achieve the anticipated benefits of the acquisition, or could reduce the earnings or otherwise adversely affect the business and financial results of the combined company. Moreover, in addition to the possible failure to realize the anticipated benefits of any acquisition, including revenues or return on investment assumptions, we may be exposed to unknown liabilities or impairment charges as a result of such acquisitions.


The market for our offeringofferings is immature and volatile, and if it does not further develop, if it develops more slowly than we expect, or if our offering doesofferings do not drive employee engagement, the growth of our business will be harmed.

Our market is immature and unproven,volatile, and it is uncertain whether we will achieve and sustain high levels of demand and market adoption. Our success depends to a substantial extent on the willingness of employers to increase their use of our health benefitsnavigation platform, the ability of our products to increase employeeuser engagement, as well as on our ability to demonstrate the value of our offeringofferings to customers and their employees and to develop new products that provide value to customers and users. If employers do not perceive the benefits of our offeringofferings or our offering doesofferings do not drive employee engagement, then our market might develop more slowly than we expect, or even shrink, which could significantly and adversely affect our operating results. In addition, we have limited insight into trends that might develop and affect our business. If customer demand for a combined
21

suite of offerings is lower than expected, our business will be harmed and our operating results will suffer.We might also make errors in predicting and reacting to relevant business, legal and regulatory trends, which could harm our business. If any of these events occur, it could materially and adversely affect our business, financial condition or results of operations.

In addition,Moreover, we are making significant investments in building a team and strategy to allow us to sell our solution to health plans, to power services they provide to their own customers, such as we have devoted substantial efforts to our acquisition of Jiff, and expect to continue to devote substantial efforts to the operation and integration of the Jiff business.with Anthem. We have undertaken these efforts and made these investments based on our belief that health plan customers would prefer to use our customers are interested insolution, rather than build one of their own, or use a combined suitesolution offered by one of offerings that address both health care management and wellness needs.our competitors. However, if customerhealth plan demand for a combined suite of offeringsour solution is lower than expected, or takes longer than we expect to develop, then our business will be harmed and our operating results will suffer.
Our quarterly results may fluctuate significantly, which could adversely impact the value of our Class B common stock.
Our quarterly results of operations, including our revenue, gross margin, net loss and cash flows, may vary significantly in the future, and period-to-period comparisons of our operating results may not be meaningful. Accordingly, our quarterly results should not be relied upon as an indication of future performance. Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control, including, without limitation, those listed elsewhere in this “Risk Factors” section and those listed below:

the addition or loss of large customers, including through acquisitions or consolidations of such customers;
seasonal and other variations in the timing of the sales of our offering, as a significantly higher proportion of our customers either enter into new subscription agreements or renew previous agreements with us in the second half of the year.
the timing of recognition of revenue, including possible delays in the recognition of revenue due to lengthy and sometimes unpredictable implementation timelines or changes brought about by new accounting pronouncements;
failure to meet our contractual commitments under service-level agreements with our customers;
the amount and timing of operating expenses related to the maintenance and expansion of our business, operations and infrastructure;
our access to pricing and claims data managed by health plans and other third parties, or changes to the fees we pay for that data;
the timing and success of introductions of new products, services and pricing by us or our competitors or any other change in the competitive dynamics of our industry, including consolidation among competitors, customers or strategic partners;
our ability to attract new customers;
customer renewal rates and the timing and terms of customer renewals;
network outages or security breaches;
the mix of products and services sold or renewed during a period;
general economic, industry and market conditions;
the timing of expenses related to the development or acquisition of technologies or businesses and potential future charges for impairment of goodwill from acquired companies; and
other impacts of new accounting pronouncements.

We are particularly subject to fluctuations in our quarterly results of operations since the costs associated with entering into customer agreements and implementing our offerings are generally incurred prior to launch, while we generally recognize revenue over the term of the agreement beginning at launch. In addition, some of our contracts with customers provide for one-time bonus payments, or in some cases fee reductions, if our offering does, or does not, achieve certain metrics, such as a certain rate of employee engagement These bonuses or reductions may lead to additional fluctuations in our quarterly operating results. In certain contracts, employee engagement may refer to the number of first time registrations by employees of our customers and in other cases it may refer to return usage of our products by employees. Any fluctuations in our quarterly results may not accurately reflect the underlying performance of our business and could cause a decline in the trading price of our Class B common stock.
We incur significant upfront costs in our customer relationships, and if we are unable to maintain and grow these customer relationships over time, we are likely to fail to recover these costs and our operating results will suffer.
We devote significant resources and incur significant upfront costs to establish relationships with our customers and implement our offeringofferings and related services, particularly in the case of large enterprises that often requestin the past have requested or requirerequired specific features or functions unique to their particular business processes. Accordingly, our operating results will depend in substantial part on our ability to deliver a successful customer experience and persuade our customers to maintain and grow their relationship with us over time. For example, if we are not successful in implementing our offeringofferings or delivering a successful customer experience, a customer could terminate or faildecline to renew their agreement with us, we would lose or be unable to recoup

19

Table of Contents



the significant upfront costs that we had expended on such customer and our operating results would suffer. As we grow, our customer acquisition costs could outpace our build-up of recurring revenue, and we may be unable to reduce our total operating costs through economies of scale such that we are unable to achieve profitability.
Similarly, we will devote significant upfront costs to developing health plan relationships, through which we expect to our services to the health plans to power their own offerings. We expect these efforts to have long lead times and require significant upfront investment by us. As part of our sales efforts, these health plans may require specific features or functions unique to their own particular businesses. Our operating results will depend in substantial part also on our ability to deliver a successful experience and persuade health plans to maintain and grow our relationships over time. If we are unable to make meaningful sales to health plans, our business will be harmed and our operating results will suffer.
Our ability to deliver our full offeringofferings to customers depends in substantial part on our ability to access data and other resources that are managed by a limited number of health plans and other third parties.
In order to deliver the full functionality offered by our health benefitsnavigation platform, we need continued access, on behalf of our customers, to sources of pricing and claims data, much of which is managed by a limited number of health plans and other third parties. We have developed various long-term and short-term processes to obtain data from certain health plans and other third parties. We are limited in our ability to offer the full functionality of our offeringofferings to customers of health plans with whom we do not have a data-sharing or joint customer support process or arrangement.


The terms of the arrangements under which we have access to data managed by health plans and other third parties vary, which can impact the offeringofferings we are able to deliver. Many of our arrangements with health plans and third parties have terms that limit our access to and permitted uses of claims or pricing data to the data associated with our mutual customers. Also, some agreements, processes, or arrangements may be terminated if the underlying customer contracts do not continue, or may otherwise be subject to termination or non-renewal in whole or in part.
    In addition, in order to deliver current and potential future functionality of our full health navigation platform, including third-party integrated services, we need access to other resources and services that are largely or fully controlled by third-party integration partners. While we have developed, and expect to continue to develop, relationships with third parties in order to allow us and our customers to access these resources and services, we are exposed to the risk that third parties may limit or eliminate our access, which would hinder our ability to provide certain integrated health navigation functionality to our customers and harm our business.
The health plans and other third parties thatwith which we currently work with may, in the future, change their position and limit or eliminate our access to data and resources, increase the costs for access, provide data and resources to us in more limited or less useful formats, or restrict our permitted uses of data and resources. Furthermore, some health plans and third parties that we rely on to supply data and resources have developed or are developing their own proprietary products and
22

Table of Contents


services that may compete with aspects of our platform, and so may perceive continued cooperation with us as a competitive disadvantage and choose to limit or discontinue our access to these data and resources. Failure to continue to maintain and expand our access to suitable pricing and other data and resources may adversely impact our ability to continue to serve existing customers and expand our offeringofferings to new customers.
If our access to the data and resources necessary to deliver health navigation functionality is eliminated, reduced or becomes more costly to us, our ability to compete in the marketplace or to grow our revenue could be impaired and our operating results would suffer.
A significant portion of our revenue comes from a limited number of customers, the loss of which would adversely affect our financial results.
Historically, we have relied on a limited number of customers for a substantial portion of our total revenue. For the year ended December 31, 2017,2020, our top 10 customers by revenue accounted for approximately 33%70% of our total revenue. Of the top 10 customers, Anthem alone accounted for approximately 47% of total revenue for the year ended December 31, 2020. We expect the top 10 concentration to increase as we pursue our strategy of selling to health plans. We rely on our reputation and recommendations from key customers in order to promote our offering to potential customers. The loss of any of our key customers, or a failure of some of them to renew or expand user subscriptions, could have a significant impact on the growth rate of our revenue, reputation and our ability to obtain new customers. For example, during the third quarter of 2018, one of our largest customers adopted a new benefits strategy and did not renew its agreement with us, and that agreement expired on December 31, 2018. In addition, mergers and acquisitions involving our customers could lead to cancellation or non-renewal of our agreements with those customers or by the acquiring or combining companies, thereby reducing the number of our existing and potential customers.

Because we generally bill our customers and recognize revenue over the term of the contract, near term declines in new or renewed agreements may not be reflected immediately in our operating results and may be difficult to discern.
Most of our revenue in each quarter is derived from agreements entered into with our customers during previous quarters. Consequently, a decline in new or renewed agreements in any one quarter may not be fully reflected in our revenue for that quarter. Such declines, however, would negatively affect our revenue in future periods and the effect of significant downturns in sales of and market demand for our offering, and potential changes in our rate of renewals or renewal terms, may not be fully reflected in our results of operations until future periods. Accordingly, management measures sales performance and forecasts future subscription revenue based on signed annual recurring revenue, or ARR. ARR is a forward-looking metric based on contractual terms in existence as of the end of a reporting period and is subject to change resulting from a number of factors including, but not limited to, addition of new customers, changes in user counts, terminations or non-renewals, renewal terms as well as upsells and cross-sells. For all of these reasons, the amount of subscription revenue we actually recognize may be different from ARR at the end of a period in which it was recorded. In addition, we may be unable to adjust our cost structure rapidly, or at all, to take account of reduced revenue. Our subscription model also makes it difficult for us to rapidly increase our total revenue through additional sales in any period, as revenue from new customers must be recognized over the applicable term of the agreement. Accordingly, the effect of changes in the industry impacting our business or changes we experience in our new sales may not be reflected in our short-term results of operations.


Our sales and implementation cycle can be long and unpredictable and require considerable time and expense, which may cause our operating results to fluctuate.

The sales cycle for our health benefitsnavigation platform, from initial contact with a potential lead to contract execution and implementation, varies widely by customer, ranging from three to 24 months. Some of our customers undertake a significant and prolonged evaluation process, including whether our offering meetsofferings meet a customer’s unique benefits program needs, that frequently involves not only the review of our offeringofferings but also of our competitors, which has in the past resulted in extended sales cycles. Our sales efforts involve educating our customers about the use, technical capabilities and benefits of our offering.offerings. Moreover, our large enterprise customers often begin to deploy our service on a limited basis, but nevertheless demand extensive configuration, integration services and pricing concessions, which increase our upfront investment in the sales effort with no guarantee that these customers will deploy our offeringofferings widely enough across their organization to justify our substantial upfront investment. It is possible that in the future we may experience even longer sales cycles, more complex customer needs, higher upfront sales costs and less predictability in completing some of our sales as we continue to expand our direct sales force and thereby increase the percentage of our sales personnel with less experience in selling our service, expand into new territories and add additional products and services.sales. In addition, even after contracts are signed, our implementation timelines can delay recognition of related revenue for several periods. If our sales
23

Table of Contents


cycle lengthens or our substantial upfront sales and implementation investments do not result in sufficient sales or revenue to justify our investments, our operating results may be harmed.
The health care industry is heavily regulated. Our failure to comply with regulatory requirements could create liability for us, result in adverse publicity and otherwise negatively affect our business.
The health care and wellness industries are heavily regulated and constantly evolving due to the changing political, legislative and regulatory landscape and other factors. Many health care and wellness laws are complex, and their application to specific services and relationships may not be clear. Further, some health care laws differ from state to state and it is difficult to ensure our business complies with evolving laws in all states. Our operations may be adversely affected by enforcement initiatives. By offering third-party partner applications we may become subject to additional regulations that don’t ordinarily apply to our own core business. Our failure to accurately anticipate the application of these laws and regulations to our business, or any other failure to comply with regulatory requirements, could create liability for us, result in adverse publicity and negatively affect our business. For example, failure to comply with these requirements could result in the unwillingness of current and potential customers to work with us. Federal and state legislatures and agencies periodically consider proposals to revise aspects of the legal rules applicable to the health care industry, or to revise or create additional statutory and regulatory requirements. Such proposals, if implemented, could impact our operations, the use of our offeringofferings and our ability to market new products and services, or could create unexpected liabilities for us. We cannot predict what changes to laws or regulations might be made in the future or how those changes could affect our business or our operating costs.

If we fail to comply with applicable health information privacy and security laws and other applicable state, federal and international privacy and security laws, we may be subject to significant liabilities, reputational harm and other negative consequences, including decreasing the willingness of current and potential customers to work with us.
We are subject to data privacy and security regulation within the jurisdictions where our users reside; these regulations address matters central to our business, including privacy and data protection, personal information, content, data security, data retention and deletion, and user communications. For example, we are subject to the Health Insurance Portability and Accountability Act of 1996 and its implementing regulations (collectively “HIPAA”),HIPAA, which established uniform federal standards for certain “covered entities,” which include health care providers and health plans, governing the conduct of specified electronic health care transactions and protecting the security and privacy of protected health information (“PHI”). The Health Information Technology for Economic and Clinical Health Act (“HITECH”) which became effective on February 17, 2010, makes HIPAA’s privacy and security standards directly applicable to “business associates,” which are independent contractors or agents of covered entities that create, receive, maintain, or transmit PHI in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA’s requirements and seek attorney’s fees and costs associated with pursuing federal civil actions.


A portion of the data that we obtain and handle for or on behalf of our customers is considered PHI, subject to HIPAA as well as other regulations. Under HIPAA and our contractual agreements with our HIPAA covered entity health plan customers, we are considered a “business associate” to those customers, and are required to maintain the privacy and security of PHI in accordance with HIPAA and the terms of our business associate agreements with customers, including by implementing HIPAA-required administrative, technical and physical safeguards. We have incurred, and will continue to incur, significant costs to establish and maintain these safeguards and, if additional safeguards are required to comply with HIPAA regulations or our customers’ requirements, our costs could increase further, which would negatively affect our operating results. Furthermore, if we fail to maintain adequate safeguards, or we or our agents and subcontractors use or disclose PHI in a manner prohibited or not permitted by HIPAA or our business associate agreements with our customers, or if the privacy or security of PHI that we obtain and handle is otherwise compromised, we could be subject to significant liabilities and consequences, including, without limitation:


breach of our contractual obligations to customers, which may cause our customers to terminate their relationship with us and may result in potentially significant financial obligations to our customers;
investigation by regulatory authorities empowered to enforce HIPAA and other applicable regulations, including but not limited to the U.S. Department of Health and Human Services and state attorneys general, and the possible imposition of civil penalties;
private litigation by individuals adversely affected by any violation of HIPAA, HITECH, or comparable laws for which we are responsible; and

negative publicity, which may decrease the willingness of current and potential future customers to work with us and negatively affect our sales and operating results.

    In addition, we are subject to various state laws, including the California Consumer Privacy Act (“CCPA”), which recently was enacted by California. The CCPA requires, among other things, that covered companies to provide new disclosures to California consumers, and affords such consumers new abilities to opt-out of certain sales of personal information. It went into effect on January 1, 2020. Legislators may propose amendments to the CCPA, and it remains unclear what, if any, modifications will be made to this legislation or how it will be interpreted in practice. We arecannot yet predict the impact of the CCPA on our business or operations, but it may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. In addition, the CCPA includes a private right of action related to security breaches. Less than one year after the CCPA became effective, California voters approved the California Privacy Rights Act (“CPRA”), a consumer privacy ballot initiative that amends and expands the CCPA. The CPRA affords California residents more control over their personal information, imposes heightened compliance requirements, and establishes a new enforcement agency dedicated to consumer privacy. The CPRA’s substantive provisions become effective January 1, 2023.

    We also in the process of becoming complianthave ongoing compliance obligations with respect to applicable portions of the EU General Data Protection Regulation (“GDPR”), which will bebecame effective on May 25, 2018, which we will have to comply with to the extent we have applicable users in the European Union, and we cannot assure you that our compliance efforts will be effective. The introduction of new products or expansion of our activities may subject us to additional laws and regulations. We have incurred, and will continue to incur, significant costs to establish and maintain compliance with new regulations that may apply to us, which would negatively affect our operating results.
Further, we publish statements to end users of our services that describe how we handle and protect personal information. If federal or state regulatory authorities or private litigants consider any portion of these statements to be untrue, we may be subject to claims of deceptive practices, which could lead to significant liabilities and consequences, including, without limitation, costs of responding to investigations, defending against litigation, settling claims and complying with regulatory or court orders.
We also send SMS text messages to potential end users who are eligible to use our service through certain customers and partners. While we get consent from or on behalf of these individuals to send text messages, federal or state regulatory authorities or private litigants may claim that the notices and disclosures we provide, form of consents we obtain or our SMS texting practices are not adequate. These SMS texting campaigns are potential sources of risk for class action lawsuits and

liability for our company. Numerous class-action suits under federal and state laws have been filed in recent years against companies who conduct SMS texting programs. Many of those suits have resulted in multi-million dollar settlements to the plaintiffs.

Our growth depends in part on the success of our strategic relationships with third parties.
In order to grow our business, we anticipate that we will continue to depend on our relationships with third parties, including Anthem, Inc. We have continued to expand our ongoing relationship with Anthem, including Anthem’s offering of Engage, a Castlight-powered health navigation platform, and our development and support of the base technology underlying Anthem’s core care guidance offering. Apart from channel partners and data partners, our offering also includes the integration of products supplied by strategic partners, who offer complementary products and services. We rely on these strategic partners in the timely and successful deployment of our offering to our customers. If the products provided by these partners have defects or do not operate as expected, if the services provided by these partners are not completed in a timely manner, if our partners have organizational or supply issues, or if we do not effectively integrate and support products supplied by these strategic partners, then we may have difficulty with the deployment of our offering that may result in loss of, or delay in, revenues, increased service and support costs and a diversion of development resources. We also may compete in some areas with these same partners. If these strategic partners fail to perform or choose not to cooperate with us on certain projects, in addition to the effects described above, we could experience loss of customers and market share; and failure to attract new customers or achieve market acceptance for our products. Identifying partners, negotiating and documenting relationships and building integrations with them, requires significant time and resources. If we are unsuccessful in establishing or maintaining our relationships with Anthem, other third parties, our ability to compete in the marketplace or to grow our revenue could be impaired and our operating results may suffer. Even if we are successful, we cannot assure you that these relationships will result in increased customer use of our platform or increased revenue.


Shifts in health care benefits trends, including any potential decline in the number of self-insured employers, or the emergence of new technologies, may render our offeringofferings obsolete or require us to expend significant resources in order to remain competitive.
The U.S. health care industry is massive,extensive and complex, with a number of large market participants with conflicting agendas, is subject to significant government regulation and is currently undergoing significant change. Changes in our industry, for example, towards private health care exchanges or away from high deductible health plans, or the emergence of new technologies as more competitors enter our market, could result in our offeringofferings being less desirable or relevant.


For example, we currently derive substantially allthe majority of our revenue from customers that are self-insured employers. The demand for significant portions of our offering dependsofferings depend on the need of self-insured employers to manage the costs of health care services that they pay on behalf of their employees. While the percentage of employers who are self-insured has been increasing over the past decade, there is no assurance that this trend will continue. Various factors, including changes in the health care insurance market or in government regulation of the health care industry, could cause the percentage of self-insured employers to decline, which would adversely affect the market for our offeringofferings and would negatively affect our business and operating results. Furthermore, such trends and our business could be affected by changes in health care spending resulting from changes in the law like we saw with the Patient Protection and Affordable Care Act (the “ACA”).Act. Under the ACA, the federal government and several state governments established public exchanges in which consumers can purchase health insurance. In the event that the ACA, any amendment or repeal of the ACA, or other changes to the legal landscape causes our customers to change their health care benefits plans or move to use of exchanges such that it reduces the need for our offering,offerings, or if the
25

Table of Contents


number of self-insured employers otherwise declines, we would be forced to compete on additional product and service attributes or to expend significant resources in order to alter our offeringofferings to remain competitive.
    
If health care benefits trends shift or entirely new technologies, services or programs are developed that replace or disrupt existing offerings, our existing or future offerings could be rendered obsolete and our business could be adversely affected. In addition, we may experience difficulties with software development, industry standards, design or marketing that could delay or prevent our development, introduction or implementation of new products and enhancements.
We may require additional capital to support business growth, and this capital might not be available to us on acceptable terms, or at all.

Our operations have consumed substantial amounts of cash since inception and we intend to continue to make significant investments to support our business growth, respond to business challenges or opportunities, develop new products

and services, enhance our existing offering and services, enhance our operating infrastructure and potentially acquire complementary businesses and technologies. For the years ended December 31, 20172020 and 2016,2019, our net cash used in operating activities was $23.5$5.6 million and $37.0$17.4 million, respectively. Our future capital requirements may be significantly different from our current estimates and will depend on many factors including our growth rate, new customer acquisitions, subscription renewal activity, operation of and integration of the Jiff business,improvement to our applications' functionalities, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the introduction of new and enhanced services offerings and the continuing market acceptance of our cloud-based subscription services. Accordingly, we might need to engage in equity or debt financings or collaborative arrangements to secure additional funds. If we raise 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 Class B common stock.

Our debt financing may expose us to risks that could adversely affect our business, operating results or financial condition, and could prevent us from fulfilling our obligations under such indebtedness. On May 5, 2020, we entered into the Amended Loan Agreement with the Bank. Under the Amended Loan Agreement, the Bank agreed to extend a $25.0 million revolving credit facility to us. The Amended Loan Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our ability to, among other things, take certain corporate actions such as incurring indebtedness, entering into acquisitions, or paying dividends. We are also required to maintain compliance with liquidity ratios. The occurrence of an event of default under the Amended Loan Agreement could result in the acceleration of all outstanding obligations under the Amended Loan Agreement. Any additional debt financing secured by us in the future could involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which might make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We might have to obtain funds through arrangements with collaborative partners or others that may require us to relinquish rights to our technologies or offeringofferings that we otherwise would not relinquish. In addition, it may be difficult to obtain financing in the public markets or to obtain additional debt financing, and we might not be able to obtain additional financing on commercially reasonable terms, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.
We depend on data centers operated by third parties for our offering,offerings, and any disruption in the operation of these facilities could adversely affect our business.
We provide our Castlight health benefitsnavigation platform and wellbeing services through computer hardware that is currently located in two geographically-dispersed, third-party data centers in the U.S., each of which areis operated by the same IT hosting company. Our JiffSome service features are augmented through the use of cloud services are hosted on Amazon Web Services hardware through virtual private clouds. Primary hosting is located at the U.S.-West availability zonespecializing in Oregon with disaster recovery/business continuity plan hosting located at the U.S.-East availability zone in Virginia.security, metrics, load balancing, and user experience. While we control and have access to our owned servers and all of the components of our network that are located in these external data centers, we do not control the operation of these facilities.facilities and there could be performance or availability issues outside our control. The owners of our data centers and hosting services have no obligation to renew the agreements with us on commercially reasonable terms, or at all. If we are unable to renew these types of agreements on commercially reasonable terms, or if our data center operators and hosting services are acquired or cease operations, we may be required to transfer our servers and other infrastructure to new data center facilities or hosting services, and we may incur significant costs and possible service interruption in connection with doing so.

Problems faced by our third-party data center and hosting locations could adversely affect the experience of our customers. The operators of the data centers and hosting services could decide to close the facilities or change and suspend their
26

Table of Contents


service offerings without adequate notice. In addition, any financial difficulties, such as bankruptcy, faced by the operators of the data centers or any of the service providers with whom we or they contract may have negative effects on our business, the nature and extent of which are difficult to predict. Additionally, if our data centers and hosting facilities are unable to keep up with our growing needs for capacity, this could have an adverse effect on our business. For example, a rapid expansion of our business could affect the service levels at our data centers and hosting locations or cause such data centers and systems to fail. Any changes in third-party service levels at our data centers and hosting locations or any disruptions or other performance problems with our product offeringofferings could adversely affect our reputation and may damage our customers’ stored files or result in lengthy interruptions in our services. Interruptions in our services might reduce our revenue, increase our costs associated with remediation or cause us to issue refunds to customers for prepaid and unused subscriptions, subject us to potential liability or adversely affect our renewal ratesrates.
The information that we provide to our customers, and their employees and families, could be inaccurate or incomplete, which could harm our business, financial condition and results of operations.
We provide price, quality and other health care-related information for use by our customers, and their employees and families, to search and compare options for health care services. Third-party health plans and our customers provide us with most of these data. Because data in the health care industry is fragmented in origin, inconsistent in format and often incomplete, the overall quality of data in the health care industry is poor, and we frequently discover data issues and errors. If the data that we provide to our customers are incorrect or incomplete or if we make mistakes in the capture or input of these data, our reputation may suffer and our ability to attract and retain customers may be harmed.
Furthermore, in the second quarter of 2020, we launched the first directory of COVID-19 testing sites for public use, as well as Working Well, a solution to help employers and academic institutions manage re-entry in the wake of the COVID-19 pandemic. There may be limited evidence on which to evaluate the market reaction to products and services that may be developed and our marketing efforts for new products and services or products with new uses may not be successful. The market for products responding to the COVID-19 pandemic is in its early stages and its future development and acceptance by our customers is uncertain. As such, there can be no assurance that any products or services will obtain significant market acceptance and fill the market need that is perceived to exist on a timely basis, or at all.Additionally, if our solutions do not accurately or securely track the health of the relevant populations, our reputation may suffer, we may be exposed to liability, and our ability to attract and retain customers may be harmed.

In addition, a court or government agency may take the position that our storage and display of health information exposes us to personal injury liability or other liability for wrongful delivery or handling of health care services or erroneous health information. While we maintain insurance coverage, this coverage may prove to be inadequate or could cease to be available to us on acceptable terms, if at all. Even unsuccessful claims could result in substantial costs, harm to our reputation and diversion of management resources. A claim brought against us that is uninsured or under-insured could harm our business, financial condition and results of operations.


If we cannot maintain our corporate culture as we grow, we could lose the elements of our culture that we believe contribute to our success and, as a result, our business may be harmed.
We believe that a critical asset for our business, and a source of our competitive strength, is our unique company culture, which we believe fosters a high level of cross-functional collaboration and desire for excellence in our performance and product. As we grow and change, we may find it difficult to maintain these important aspects of our corporate culture. OurThis was true in the case of the Jiff acquisition, and may be true of Jiff, andany acquisitions we may make in the further integration of Jiff’s business and personnel into our company,future. Any such acquisitions may present additional challenges to our ability to maintain our corporate culture. Any failure to preserve our culture could also negatively affect our reputation, our ability to attract and retain personnel, our reputation and our ability to continue to build and advance our offeringofferings and may otherwise adversely affect our future success.
If we fail to develop widespread brand awareness cost-effectively, our business may suffer.
We believe that developing and maintaining widespread awareness of our brand in a cost-effective manner is critical to achieving widespread adoption of our offeringofferings and attracting new customers. Brand promotion activities may not generate customer awareness or increase revenue, and even if they do, any increase in revenue may not offset the expenses we incur in building our brand. If we fail to successfully promote and maintain our brand, or incur substantial expenses, we may fail to attract or retain customers necessary to realize a sufficient return on our brand-building efforts, or to achieve the widespread brand awareness that is critical for broad customer adoption of our offering.offerings.

Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.
    Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Our estimates and forecasts relating to the size and expected growth of the market for our products and services may prove to be inaccurate. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.

Any failure to protect our intellectual property rights could impair our ability to protect our proprietary technology and our brand.
Our success depends in part on our ability to enforce our intellectual property and other proprietary rights. We rely upon a combination of patent, trademark, copyright and trade secret laws, as well as license and access agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. In addition, we attempt to protect our intellectual property and proprietary information by requiring certain of our employees, consultants and contractors to enter into confidentiality, noncompetition and assignment of inventions agreements. These laws, procedures and restrictions provide only limited protection and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed or misappropriated. While we have fourtwo U.S. patent applications pending, and we currently have one issued U.S. patent, we cannot ensure that any of our pending patent applications will be granted or that our issued patent will adequately protect our intellectual property. In addition, if any patents are issued in the future, they may not provide us with any competitive advantages, or may be successfully challenged by third parties. To the extent that our intellectual property and other proprietary rights are not adequately protected, third parties might gain access to our proprietary information, develop and market solutions similar to ours, or use trademarks similar to ours, each of which could materially harm our business. Further, unauthorized parties may attempt to copy or obtain and use our technology to develop products with the same functionality as our offering, and policing unauthorized use of our technology and intellectual property rights is difficult and may not be effective. The failure to adequately protect our intellectual property and other proprietary rights could materially harm our business.
We could incur substantial costs as a result of any claim of infringement of another party’s intellectual property rights.
In recent years, there has been significant litigation in the United States involving patents and other intellectual property rights. Companies in the Internet and technology industries are increasingly bringing and becoming subject to suits alleging infringement of proprietary rights, particularly patent rights, and our competitors and other third parties may hold patents or have pending patent applications, which could be related to our business. These risks have been amplified by the increase in third parties, which we refer to as non-practicing entities, whose sole or primary business is to assert such claims. We expect that we may receive in the future notices that claim we or our customers using our offeringofferings have misappropriated or misused other parties’ intellectual property rights, particularly as the number of competitors in our market grows and the functionality of products amongst competitors overlaps. If we are sued by a third party that claims that our technology infringes its rights, the litigation, whether or not successful, could be extremely costly to defend, divert our management’s time, attention and

25

Table of Contents



resources, damage our reputation and brand and substantially harm our business. We do not currently have an extensive patent portfolio of our own, which may limit the defenses available to us in any such litigation.
In addition, in most instances, we have agreed to indemnify our customers against certain third-party claims, which may include claims that our offering infringesofferings infringe the intellectual property rights of such third parties. Our business could be adversely affected by any significant disputes between us and our customers as to the applicability or scope of our indemnification obligations to them. The results of any intellectual property litigation to which we might become a party, or for which we are required to provide indemnification, may require us to do one or more of the following:
cease offering or using technologies that incorporate the challenged intellectual property;
make substantial payments for legal fees, settlement payments or other costs or damages;
obtain a license, which may not be available on reasonable terms, to sell or use the relevant technology; or
incur substantial costs and reallocate resources to redesign our technology to avoid infringement.


If we are required to make substantial payments or undertake any of the other actions noted above as a result of any intellectual property infringement claims against us or any obligation to indemnify our customers for such claims, such payments or costs could have a material adverse effect upon our business and financial results.
Our use of open source technology could impose limitations on our ability to commercialize our software platform.
28

Table of Contents


Our offering incorporatesofferings incorporate open source software components that are licensed to us under various public domain licenses. Some open source software licenses require users who distribute open source software as part of their software to publicly disclose all or part of the source code to such software or make available any derivative works of the open source code on unfavorable terms or at no cost. There is little or no legal precedent governing the interpretation of many of the terms of these licenses and therefore the potential impact of such terms on our business is somewhat unknown. There is a risk that such licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to market our software platform. While we monitor our use of open source software and try to ensure that none is used in a manner that would require us to disclose our source code or that would otherwise breach the terms of an open source agreement, such use could inadvertently occur and we may be required to release our proprietary source code, pay damages for breach of contract, re-engineer our offering,offerings, discontinue sales of our offeringofferings in the event re-engineering cannot be accomplished on a timely basis or take other remedial action that may divert resources away from our development efforts, any of which could cause us to breach customer contracts, harm our reputation, result in customer losses or claims, increase our costs or otherwise adversely affect our business and operating results.

We may face risks related to securities litigation that could result in significant legal expenses and settlement or damage awards.

We have been in the past and may in the future become subject to claims and litigation alleging violations of the securities laws or other related claims, which could harm our business and require us to incur significant costs. For example, during the second quarter of 2015, four purported securities class action lawsuits, which were later consolidated into a single action, were filed in the Superior Court of the State of California, County of San Mateo, against the Company, certain of its current and former directors, executive officers, significant stockholders and underwriters associated with its initial public offering (“IPO”). The lawsuits were brought by purported stockholders of the Company seeking to represent a class consisting of all those who purchased the Company’s stock pursuant or traceable to the Registration Statement and Prospectus issued in connection with its IPO, alleging claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933. We are generally obliged, to the extent permitted by law, to indemnify our current and former directors and officers who are named as defendants in these types of lawsuits. On March 28, 2016, the parties to the consolidated actions reached a mutually acceptable resolution by way of a mediated cash settlement for an aggregate amount of $9.5 million and the Court entered final approval of the settlement on October 28, 2016. As a result of the settlement Castlight recorded a net charge of $2.9 million to general and administrative expense in 2016. This amount represents the portion of settlement that was not covered by insurance and legal fees incurred in 2016 regarding this matter. Future litigation may require significant attention from management and could result in significant legal expenses, settlement costs or damage awards that could have a material impact on our financial position, results of operations and cash flows.

The development and expansion of our business through acquisitions of other companies or technologies or other strategic transactions could divert our management’s attention, result in dilution to our stockholders and otherwise disrupt our operations and adversely affect our operating results.
On April 3, 2017, we completed our acquisition of Jiff, and issued approximately 27 million shares and options to former Jiff equity holders, representing approximately 20% of the combined company on a fully-diluted basis. The process of integrating the Jiff business, team and technology has created, and will continue to create, unforeseen operating difficulties and expenditure requirements. We may not be able to effectively manage the combined Castlight and Jiff business, or effectively integrate the personnel, operations and technologies of Jiff.
In addition, in 2015, we made a preferred stock investment in Lyra Health of $4.1 million, associated with a strategic alliance with Lyra Health, which we subsequently divested in 2017. In May 2016, we also sold and issued to SAP Technologies, Inc., or SAP, approximately 4.7 million shares of our Class B Common Stock and a warrant to purchase up to approximately 1.9 million shares of our Class B Common Stock. The warrant expired on its terms without becoming exercisable as we did not enter into an alliance agreement with SAP related to the distribution and the reselling of our solutions by November 17, 2017.
As we have done in the past, we may in the future seek to acquire or invest in businesses, products and services or technologies or enter into other strategic transactions that we believe could complement or expand our offering, enhance our technical capabilities or otherwise offer growth opportunities. We have limited experience in acquiring other businesses and entering into strategic transactions. We may not achieve any of the anticipated benefits of any of these strategic transactions. The pursuit of potential acquisitions and other strategic transactions may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing suitable acquisitions and strategic alliances or transactions, whether or not they are consummated. We may not achieve any of the anticipated benefits or stated objectives from these or other strategic transactions we may enter into in the future.
Factors affecting our ability to achieve the benefits of the Jiff acquisition, other acquisitions or other strategic alliances     could include:

inability to integrate or benefit from acquired technologies or services or strategic collaborations or alliances in an efficient, effective or profitable manner;
unanticipated costs or liabilities associated with the acquisition or strategic transaction;
challenges in achieving strategic objectives, cost savings and other benefits expected from such transactions;
the lack of unilateral control over a strategic alliance and the risk that strategic partners have business goals and interests that are not aligned with ours;
delays, difficulties or unexpected costs in the integration, assimilation, implementation or modification of platforms, systems, functions, technologies and infrastructure to support the combined business or strategic alliance, as well as maintaining and integrating accounting systems and operations, uniform standards, controls (including internal accounting controls), procedures and policies
difficulty converting the customers of the acquired business onto our platform and contract terms, including disparities in the revenue, licensing, support or professional services model of the acquired company;
diversion of management’s attention from other business concerns;
adverse effects to our existing business relationships with business partners and customers as a result of the acquisition or strategic transaction;
the potential loss of key employees;
the risk that we do not realize a satisfactory return on our investments;
use of resources that are needed in other parts of our business; and
use of substantial portions of our available cash to consummate the acquisition or strategic transaction.

In addition, a significant portion of the purchase price of Jiff, and other companies we acquire or invest in, may be allocated to acquired goodwill and other intangible assets, which must be assessed for impairment at least annually. In the future, if our acquisitions do not yield expected returns, we may be required to take charges to our operating results based on this impairment assessment process, which could adversely affect our results of operations.

The acquisition of Jiff resulted, and other acquisitions and strategic transactions could also result, in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our operating results. In addition, if an acquired business or other strategic transaction fails to meet our expectations, our operating results, business and financial position may suffer.

If we are unable to implement and maintain effective internal control over financial reporting in the future, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our Class B common stock may be negatively affected.
As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control. Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, requires that we evaluate and determine the effectiveness of our internal control over financial reporting and, provide a management report on the internal control over financial reporting. Our independent registered public accounting firm is not required to audit the effectiveness of our internal control over financial reporting until after we are no longer an “emerging growth company”, as defined in the JOBS Act. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting is documented, designed or operating. If we have a material weakness in our internal control over financial reporting, we may not detect errors on a timely basis and our financial statements may be materially misstated. We are in the process of designing and implementing the internal control over financial reporting required to comply with this obligation, which process will be time consuming, costly and complicated. If we identify material weaknesses in our internal control over financial reporting, if we are unable to comply with the requirements of Section 404 in a timely manner, if we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm concludes we have a material weakness in our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our Class B common stock could be negatively affected and we could become subject to investigations by the New York Stock Exchange, on which our securities are listed, the SEC or other regulatory authorities, which could require us to obtain additional financial and management resources.
Changes in accounting principles may cause previously unanticipated fluctuations in our financial results, and the implementation of such changes may impact our ability to meet our financial reporting obligations.
We prepare our financial statements in accordance with U.S. GAAP which are subject to interpretation or changes by the Financial Accounting Standards Board, or FASB, the SEC, and other various bodies formed to promulgate and interpret appropriate accounting principles. New accounting pronouncements and changes in accounting principles have occurred in the past and are expected to occur in the future which may have a significant effect on our financial results. For example, in May 2014, the FASB issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers,” which supersedes most current revenue recognition guidance, including industry-specific guidance. We are required to implement this new revenue standard for our fiscal year beginning January 1, 2018. We plan to adopt under the full retrospective method. Based on our assessment to date, we currently believe a significant impact from the adoption of the new standard will be related to our costs to fulfill as well as our costs to obtain contracts with customers. For fulfillment costs, the new standard states that an entity shall recognize an asset from the costs incurred to fulfill a contract if certain criteria are met. Similar to fulfillment costs, for costs to obtain a contract (which are primarily sales commissions and broker fees), the standard states that costs to obtain a contract shall be amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. We currently expense costs to fulfill a contract when they are incurred, capitalize certain sales commissions and amortize those costs over the non-cancelable portion of our subscription contracts. Under the new standard, the amortization period for our costs to obtain a contract could be longer. Additionally, we expect the timing of revenue recognition for certain of our revenue arrangements to be impacted by the changes imposed by the new standard. We are continuing to evaluate the effect that the new standard will have on our consolidated financial statements and our preliminary assessments remain subject to change. Any difficulties in implementation of changes in accounting principles, including the ability to modify our accounting systems, could cause us to fail to meet our financial reporting obligations, which could result in regulatory discipline and harm investors’ confidence in us.
We incur significantly increased costs and devote substantial management time as a result of operating as a public company.
As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company. For example, we are subject to the reporting requirements of the Exchange Act and are required to comply with the applicable requirements of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules and regulations subsequently implemented by the SEC and the New York Stock Exchange, including the establishment and maintenance of effective disclosure and financial controls, changes in corporate governance practices and required filing of annual, quarterly and current reports with respect to our business and operating results. Compliance with these requirements increases our legal and financial compliance costs and makes some activities more time consuming and costly. In addition, our management and other personnel divert attention from operational and other business matters to devote substantial

time to these public company requirements. In particular, we incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act, which will increase when we are no longer an emerging growth company, as defined by the JOBS Act.

Operating as a public company makes it more expensive for us to obtain director and officer liability insurance, and in the future we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. This could also make it more difficult for us to attract and retain qualified people to serve on our board of directors, our board committees or as executive officers.
We are an emerging growth company and the reduced disclosure requirements applicable to emerging growth companies may make our Class B common stock less attractive to investors.
We are an emerging growth company, as defined under the JOBS Act. For as long as we continue to be an emerging growth company, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our Class B common stock less attractive because we will rely on these exemptions. If some investors find our Class B common stock less attractive as a result, there may be a less active trading market for our Class B common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earliest of (i) the end of the year in which the market value of our Class B common stock that is held by non-affiliates exceeds $700 million as of June 30, (ii) the end of the year in which we have total annual gross revenue of $1 billion or more during such year, (iii) the date on which we issue more than $1 billion in non-convertible debt in a three-year period or (iv) December 31, 2019.
We may not be able to utilize a significant portion of our net operating loss or research tax credit carryforwards, which could adversely affect our profitability.
Our primary tax jurisdiction is the United States. All of our tax years are open to examination by U.S. federal and state tax authorities due to our history of tax losses.authorities. We have provided a full valuation allowance for our deferred tax assets due to the uncertainty surrounding the future realization of such assets. Therefore, no benefit has been recognized for the net operating loss carryforwards and other deferred tax assets. The net operating loss could expire unused and be unavailable to reduce future income tax liabilities, which could adversely affect our profitability.
Economic uncertainties or downturns in the general economy or the industries in which our customers operate could disproportionately affect the demand for our offering
We are a smaller reporting company and negatively impact our results of operations.
General worldwide economic conditions have experienced periods of significant downturn, and market volatility and uncertainty remain widespread, making it extremely difficult for our customers and usmay elect to accurately forecast and plan future business activities. For example, in June 2016, the decision by referendumcomply with reduced public company reporting requirements applicable to withdraw the United Kingdom (U.K.) from the European Union caused significant volatility in global stock markets, including those in the U.S., and fluctuations in currency exchange rates. The results of this referendum, or other global events, may continue to create global economic uncertainty not only in the U.K., but in other regions, including where we do business. In addition, these conditions could cause our customers or prospective customers to decrease headcount, benefits or human resources budgets,smaller reporting companies, which could decrease corporate spending onmake our productscommon stock less attractive to investors.

We are a “smaller reporting company,” meaning that we are not an investment company, an asset-backed issuer, or a majority-owned subsidiary of a parent company that is not a “smaller reporting company,” and services, resultinghave either: (i) a public float of less than $250 million or (ii) annual revenues of less than $100 million during the most recently completed fiscal year and (A) no public float or (B) a public float of less than $700 million. As a “smaller reporting company,” we are subject to reduced disclosure obligations in delayedour SEC filings compared to other issuers, including with respect to disclosure obligations regarding executive compensation in our periodic reports and lengthened sales cycles,proxy statements. Until such time as we cease to be a decrease“smaller reporting company,” such reduced disclosure in new customer acquisitionour SEC filings may make it harder for investors to analyze our operating results and loss of customers. Furthermore, during challenging economic times,financial prospects.

If some investors find our customers may have difficulty gaining timely access to sufficient credit or obtaining credit on reasonable terms, which could impair their ability to make timely payments to us and adversely affect our revenue. If that were to occur, our financial results could be harmed. Further, challenging economic conditions might impair the ability of our customers to pay for the products and services they already have purchased from us and,common stock less attractive as a result our write-offs of accounts receivable could increase. We cannot predict the timing, strength, or duration of any economic slowdown or recovery.

Risks Related to Our Class B Common Stock

The stock price of our Class B common stock may be volatile or may decline regardless of our operating performance.


The market price of our Class B common stock has fluctuated significantly since our initial public offering and may continue to fluctuate. These fluctuations could cause you to lose all or part of your investment in our Class B common stock. Factors, many of which are beyond our control, that could cause additional fluctuations in the market price of our Class B common stock include the following:


overall performance of the equity markets;
the COVID-19 pandemic and any associated economic downturn;
our operating performance and the performance of other similar companies;
changes in the estimates of our operating results that we provide to the public or our failure to meet these projections;
failure of securities analysts to maintain coverage of us, changes in financial estimates by securities analysts who follow our company or our failure to meet these estimates or the expectations of investors or changes in recommendations by securities analysts that elect to follow our Class B common stock;
sales of shares of our Class B common stock by us or our stockholders, including same day sales to cover tax withholdings as a result of settlement of restricted stock units;
announcements of technological innovations, new products or enhancements to services, acquisitions, strategic alliances or significant agreements by us or by our competitors;

disruptions in our services due to computer hardware, software or network problems;
announcements of customer additions and customer cancellations or delays in customer purchases;
recruitment or departure of key personnel;
the economy as a whole, market conditions in our industry and the industries of our customers;
litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;
developments or disputes concerning our intellectual property or other proprietary rights;
new laws or regulations or new interpretations of existing laws or regulations applicable to our business; and
the size of our market float.
In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have filed securities class action litigation following periods of market volatility.volatility or have threatened other actions, including proxy contests. If we were to become involved in new securities litigation or become subjected to a proxy contest, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business.

If we are unable to meet the continued listing requirements of the NYSE, the NYSE may delist our Class B common stock.

On March 30,

Table 2020, we received written notification from the NYSE that the average closing price of Contentsour Class B common stock had fallen below $1.00 per share over a period of 30 consecutive trading days, which is the minimum average closing share price required to maintain listing under Section 802.01C of the NYSE Listed Company Manual. On September 1, 2020, we regained compliance with NYSE listing requirements after our average closing price for the 30 trading days ended August 31, 2020 and our closing price on August 31, 2020 both exceeded $1.00 per share.



If in the future our trading price fails to comply with NYSE listing standards, we may receive an additional deficiency notice. In the future, we could elect to regain compliance by implementing a reverse stock split, such that the price of our Class B common stock would promptly exceed $1.00 per share, provided that the price must remain above that level for at least the following 30 trading days. At our 2020 annual meeting of stockholders, we received stockholder approval for a reverse stock split, which approval is effective until our 2021 annual meeting of stockholders should our Board decide to implement a reverse stock split to cure a future deficiency.


Our Class B common stock could also be delisted if (i) our average market capitalization over a consecutive 30 trading-day period is less than $15 million, or (ii) our Class B common stock trades at an “abnormally low” price. In either case, we would not have an opportunity to cure the deficiency, and, as a result, our Class B common stock would be suspended from trading on the NYSE immediately, and the NYSE would begin the process to delist our Class B common stock, subject to our right to appeal under NYSE rules. If this were to occur, there is no assurance that any appeal we undertake in these or other circumstances would be successful, nor is there any assurance that we will continue to comply with the other NYSE continued listing standards.

Failure to maintain our NYSE listing could negatively impact us and our stockholders by reducing the willingness of investors to hold our Class B common stock because of the resulting decreased price, liquidity and trading of our Class B common stock, limited availability of price quotations, and reduced news and analyst coverage. These developments may also require brokers trading in our Class B common stock to adhere to more stringent rules and may limit our ability to raise capital by issuing additional shares in the future. Delisting may adversely impact the perception of our financial condition and cause reputational harm with investors and parties conducting business with us. In addition, the perceived decreased value of employee equity incentive awards may reduce their effectiveness in encouraging performance and retention.

If there are substantial sales of shares of our Class B common stock, the price of our Class B common stock could decline.
The price of our Class B common stock could decline if there are substantial sales of our Class B common stock, particularly sales by our directors, executive officers and significant stockholders, or the perception in the market that the holders of a large number of shares of our Class B common stock intend to sell their shares, and may make it more difficult for stockholders to sell Class B common stock at a time and price that they deem appropriate. We are unable to predict the effect that sales may have on the prevailing market price of our Class B common stock.
In addition, certain
30

Table of our stockholders have rights, subject to some conditions, to require us to file registration statements covering their shares and to include their shares in registration statements that we may file for ourselves or our stockholders. Registration of the resale of these shares under the Securities Act would generally result in the shares becoming freely tradable without restriction. Any sales of securities by existing stockholders could adversely affect the trading price of our Class B common stock. We also registered shares of Class B common stock that we have issued and may issue under our employee equity incentive and employee stock purchase plans. These shares may be sold freely in the public market upon issuance.Contents


The dual class structure of our Class A and Class B common stock will have the effect of concentrating significant voting influence or control with our executive officers, directors and their affiliates; this will limit or preclude a stockholder's ability to influence corporate matters.
Each share of Class A common stock and each share of Class B common stock has one vote per share, except on the following matters (in which each share of Class A common stock has ten votes per share and each share of Class B common stock has one vote per share):

adoption of a merger or consolidation agreement involving our company;
a sale, lease or exchange of all or substantially all of our property and assets;
a dissolution or liquidation of our company; or
every matter, if and when any individual, entity or “group” (as such term is used in Regulation 13D of the Exchange Act) has, or has publicly disclosed (through a press release or a filing with the SEC) an intent to have, beneficial ownership of 30% or more of the number of outstanding shares of Class A common stock and Class B common stock, combined.
Because of our dual class common stock structure, the holders of our Class A common stock, who in large part consist of our founders, early investors, directors, executives,and current and former employees, will continue to be able to exert significant influence over the corporate matters listed above if any such matter is submitted to our stockholders for approval even if they own less than 50% of the outstanding shares of our Class A and Class B common stock, combined. As of December 31, 2017,2020, holders of our Class A common stock owned approximately 39%22% of the outstanding shares of our Class A and Class B common stock, combined,combined; however, holders of our Class A common stock, including our executive officers and directors and their affiliates, have approximately 87%74% of the voting power of our outstanding capital stock with respect to the matters specified above. This concentrated control by holders of our Class A common stock will limit or preclude the ability of a holder of our Class B common stock to influence those corporate matters for the foreseeable future and, as a result, we may take actions that our stockholders do not view as beneficial. The market price of our Class B common stock could be adversely affected by the structure. In addition, this may prevent or discourage unsolicited acquisition proposals or offers for capital stock that a stockholder may feel are in its best interests.
Transfers by holders of our Class A common stock will generally result in those shares converting to our Class B common stock, subject to limited exceptions, such as certain transfers effected for estate planning purposes. The conversion of our Class A common stock to our Class B common stock will have the effect, over time, of increasing the relative voting power of those holders of Class A common stock who retain their shares in the long term. If, for example, directors and their affiliates retain a significant portion of their holdings of our Class A common stock for an extended period of time, they could continue to significantly influence the combined voting power of our Class A and Class B common stock with respect to each of the matters identified in the list above.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.
The trading market for our Class B common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our Class B common stock or publish inaccurate or unfavorable research about our business, our Class B common stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our Class B common stock could decrease, which might cause our Class B common stock price and trading volume to decline.


Anti-takeover provisions under Delaware law and in our restated certificate of incorporation and restated bylaws could make a merger, tender offer, or proxy contest difficult, limit attempts by our stockholders to replace or remove members of our board of directors or current management and depress the trading price of our Class B common stock.
Our status as a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay, or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders.
In addition, our restated certificate of incorporation and restated bylaws contain provisions that may make the acquisition of our company or changes in our board of directors or management more difficult, including the following:
31

Table of Contents


Our board of directors is classified into three classes of directors with staggered three-year terms and directors are only able to be removed from office for cause, which may delay the replacement of a majority of our board of directors or impede an acquirer from rapidly replacing our existing directors with its own slate of directors.
Subject to the rights of the holders of any series of preferred stock to elect directors under specified circumstances, only our board of directors has the right to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors.
Our stockholders may not act by written consent or call special stockholders’ meetings; as a result, a holder, or holders, controlling a majority of our Class A and Class B common stock are not be able to take certain actions other than at annual stockholders’ meetings or special stockholders’ meetings, which special meetings may only be called by the chairman of our board, our chief executive officer, our president, or a majority of our board of directors.
Certain litigation against us can only be brought in Delaware.Delaware and actions related to securities claims can only be brought in federal court.
Our restated certificate of incorporation authorizes undesignated preferred stock, the terms of which may be established and shares of which may be issued, by our board of directors without the approval of the holders of Class B common stock, which makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to acquire us.
Advance notice procedures and additional disclosure requirements apply for stockholders to nominate candidates for election as directors or to bring matters before a meeting of stockholders, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company.
Our restated certificate of incorporation prohibits cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates.
Amendment of the anti-takeover provisions of our restated certificate of incorporation require super majority approval by holders of at least two-thirds of our outstanding Class A and Class B    common stock, combined. and
In certain circumstances pertaining to change in control, the sale of all or substantially all of our assets and liquidation matters, and on all matters if and when any individual, entity or group has, or has publicly disclosed an intent to have, beneficial ownership of 30% or more of the number of outstanding shares of our Class A and Class B common stock, combined, holders of our Class A common stock are entitled to ten votes per share and holders of our Class B common stock are entitled to one vote per share. As of December 31, 2017,2020, holders of our Class A common stock owned approximately 39%22% and holders of our Class B common stock owned approximately 61%78% of the outstanding shares of our Class A and Class B common stock, combined. However, because of our dual class common stock structure these holders of our Class A common stock have approximately 87%74% and holders of our Class B common stock have approximately 13%26% of the total votesvoting power with respect to the matters specified above. In all other circumstances, holders of our Class A and Class B common stock are each entitled to one vote per share, and in these other circumstances the holders of our Class A common stock have approximately 39%22% and holders of our Class B common stock have approximately 61%78% of the total votes.voting power.

In addition, in December 2020, we amended and restated our restated bylaws to provide that the federal district courts of the United States will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (such provision, a “Federal Forum Provision”). Our decision to adopt a Federal Forum Provision followed a decision by the Supreme Court of the State of Delaware holding that such provisions are facially valid under Delaware law. While there can be no assurance that federal or state courts will follow the holding of the Delaware Supreme Court or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision means that suits brought by our stockholders to enforce any duty or liability created by the Securities Act of 1933, as amended, must be brought in federal court and cannot be brought in state court.

General Risks

The COVID-19 pandemic has had a material adverse impact on the U.S. and global economies and could have a material adverse impact on our employees, suppliers, customers and users, which has negatively impacted our business, financial condition and results of operations and which could materially impact us in the future.

During the first quarter of 2020, a novel coronavirus disease (“COVID-19”) was declared a global pandemic by the World Health Organization and has resulted in the imposition by national, state and local governments of numerous, unprecedented, national and international measures to try to contain the virus, including travel bans and restrictions, shutdowns,
32

Table of Contents





quarantines, shelter-in-place and social distancing orders, many of which have adversely impacted consumer spending, global capital markets and the global economy.


The COVID-19 pandemic has caused us to modify our business practices, including but not limited to: instituting a workforce reduction in May 2020 representing 13% of our headcount; implementing a temporary base salary reduction for executive management, directors and other employees, which was restored in mid-November 2020; curtailing or modifying employee travel; cancelling physical participation in meetings, events and conferences; and moving to full remote work for certain offices. We may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers and business partners. Our San Francisco and Sunnyvale, California offices currently remain closed as a result of health department mandates. However, we have re-opened our Utah offices for certain employees as allowed under state and local orders. While we have implemented what we believe to be a comprehensive protocol to ensure the safety and wellbeing of employees returning to the office, including daily health screenings, physical changes to our floor layout, and required proper personal protection equipment, these measures may not be sufficient to mitigate the risks posed by the virus or otherwise be satisfactory to government authorities.

The COVID-19 pandemic has adversely affected, and may continue to adversely affect, our customers’ operations, our employees, and employee productivity. For example, some of our customers have experienced reductions in force that have negatively impacted the fees due to us under our agreements with them. In addition, we have experienced some changes in customer demand, particularly as customer funding priorities change and some of our buyers' budgets are cut, which has caused us to offer deferred payment terms and discounts in lieu of termination, and has also resulted in some terminations or non-renewals. The uncertainty of the COVID-19 pandemic on our customers' operations, our employees, and their productivity affects our management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information become known.

Additionally, the disruption and volatility in the global and domestic capital markets may increase the cost of capital and limit our ability to access capital. Both the health and economic aspects of the COVID-19 virus are highly fluid and the future course of each is uncertain. For these reasons and other reasons that may come to light if the COVID-19 pandemic and associated protective or preventative measures expand, we may experience a material adverse effect, either directly or indirectly through our customers, on our business operations, revenues, and financial condition; however, its ultimate impact is highly uncertain and subject to change.

Our quarterly results may fluctuate significantly, which could adversely impact the value of our Class B common stock.
Our quarterly results of operations, including our revenue, gross margin, net loss and cash flows, may vary significantly in the future, and period-to-period comparisons of our operating results may not be meaningful. Accordingly, our quarterly results should not be relied upon as an indication of future performance. Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control, including, without limitation, those listed elsewhere in this “Risk Factors” section and those listed below:
the addition or loss of large customers, including through acquisitions or consolidations of such customers;
seasonal and other variations in the timing of the sales of our offerings, as a significantly higher proportion of our customers either enter into new subscription agreements or renew previous agreements with us in the second half of the year;
the timing of recognition of revenue, including possible delays in the recognition of revenue due to lengthy and sometimes unpredictable implementation timelines;
failure to meet our contractual commitments under service-level agreements with our customers;
the amount and timing of operating expenses related to the maintenance and expansion of our business, operations and infrastructure;
our access to pricing and claims data managed by health plans and other third parties, or changes to the fees we pay for that data;
the timing and success of introductions of new products, services and pricing by us or our competitors or any other change in the competitive dynamics of our industry, including consolidation among competitors, customers or strategic partners;
our ability to attract new customers;
customer renewal rates and the timing and terms of customer renewals;
network outages or security breaches;
the mix of products and services sold or renewed during a period;
33

Table of Contents


general economic, industry and market conditions, including the domestic and global macroeconomic impact of the current COVID-19 pandemic;
the timing of expenses related to the development or acquisition of technologies or businesses and potential future charges for impairment of goodwill from acquired companies; and
impacts of new accounting pronouncements.
    We are particularly subject to fluctuations in our quarterly results of operations since the costs associated with entering into customer agreements and implementing our offerings are generally incurred prior to launch, while we generally recognize revenue over the term of the agreement beginning at launch. In addition, some of our contracts with customers provide for one-time bonus payments, or in some cases fee reductions, if our offerings do, or do not, achieve certain metrics, such as a certain rate of employee engagement. These bonuses or reductions may lead to additional fluctuations in our quarterly operating results. In certain contracts, employee engagement may refer to the number of first time registrations by employees of our customers and in other cases it may refer to return usage of our products by employees. Any fluctuations in our quarterly results may not accurately reflect the underlying performance of our business and could cause a decline in the trading price of our Class B common stock.
The loss of one or more of our executive officers or key employees, or an inability to attract and retain highly skilled employees or key subcontractor services, could adversely affect our business.

Our success depends largely upon the continued services of our key executive officers. We have in the past and may in the future experience changes in our executive management team resulting from the departure of executives or subsequent hiring of new executives, which may be disruptive to our business. Transitions in senior management may disrupt our ability to implement our business strategy and could have a material adverse effect on our business. The impact of hiring new executives may not be immediately realized.

Our executive officers are at-will employees and may terminate employment with us at any time with no advance notice. The replacement of one or more of our executive officers or other key employees involves significant time and cost and may significantly delay or prevent the achievement of our business objectives.

To continue to execute our growth strategy, we also must attract and retain highly skilled personnel, particularly in research and development and sales and marketing. Competition is intense for engineers with high levels of experience in designing and developing software and Internet-related services, particularly in the San Francisco Bay Area where we are located. The pool of qualified personnel with Software-as-a-Service, or SaaS, experience or experience working with the health care market is limited overall. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled personnel with appropriate qualifications.In addition, many of the companies with which we compete for experienced personnel have greater resources than we do. We supplement our hired skilled personnel through the use of subcontractors, particularly in the area of research and development, a significant portion of which perform services outside of the United States. If these subcontractors cease to perform services for us for any reason, our ability to meet our development goals may be impaired, and our business and future growth prospects could be severely harmed.

In addition, in making employment decisions, particularly in the Internet and high-technology industries, job candidates often consider the value of the stock options or other equity instruments they may receive in connection with their employment. Volatility or performance trends in the price of our stock may, therefore, adversely affect our ability to attract or retain highly skilled personnel.
If we fail to manage our growth effectively, our expenses could increase more than expected, our revenue may not increase and we may be unable to implement our business strategy.
    We have experienced significant growth since our inception, both organic and through acquisitions, which strains our business, operations and employees. Future revenues may not grow at the same rates they have historically or may even stagnate or decline. To manage our current and anticipated future growth effectively, we must continue to maintain and enhance our IT infrastructure, financial and accounting systems and controls. Moreover, we may from time to time decide to undertake cost savings initiatives, such as the reduction in workforce we implemented in 2020, or disposing of, or otherwise discontinuing certain products, in an effort to focus our resources on key strategic initiatives and streamline our business. We must also attract, train and retain a significant number of qualified personnel in key areas such as research and development, sales and
34

Table of Contents


marketing, customer support, professional services, and management, and the availability of such personnel, in particular software engineers, may be constrained. These and similar challenges, and the related costs, may be exacerbated by the fact that our headquarters is located in the San Francisco Bay Area.
    A key aspect to managing our growth is our ability to scale our capabilities to implement our offerings satisfactorily with respect to both large and demanding enterprise customers, who currently comprise the majority of our customer base, as well as smaller customers. Large customers often require specific features or functions unique to their particular business processes, which at a time of rapid growth or during periods of high demand may strain our implementation capacity and hinder our ability to successfully implement our offerings to our customers in a timely manner. We may also need to make further investments in our technology and automate portions of our offerings or services to decrease our costs, particularly as we grow sales of our health navigation platform to smaller customers. If we are unable to address the needs of our customers or their employees, or our customers or their employees are unsatisfied with the quality of our offerings or services, they may not renew their agreements, seek to cancel or terminate their relationship with us, or renew on less favorable terms. In addition, many of our customers adjust their benefit plan designs, benefits providers, and eligibility criteria at the start of each new benefits plan year, requiring additional configurations for those customers. As our customer base grows, the complexity of these activities may increase. If we fail to automate these operations sufficiently and implement these changes on a timely basis or are unable to implement them effectively, our business may suffer.

Failure to effectively manage our growth could also lead us to over-invest or under-invest in development and operations; result in weaknesses in our infrastructure, systems or controls; give rise to operational mistakes, financial losses, loss of productivity or business opportunities; and result in loss of employees and reduced productivity of remaining employees. Our growth is expected to require significant capital expenditures and might divert financial resources from other projects such as the development of new products and services. In addition, data and content fees, which are one of our primary operational costs, are not fixed as they vary based on the source and condition of the data we receive from third parties, and if they remain variable or increase over time, we would not be able to realize the economies of scale that we expect as we grow renewals and implementation of new customers, which may negatively impact our gross margin. If our management is unable to effectively manage our growth, our expenses might increase more than expected; our revenue may not increase or might grow more slowly than expected; and we might be unable to implement our business strategy. The quality of our offerings might also suffer, which could negatively affect our reputation and harm our ability to retain and attract customers.
If we are unable to implement and maintain effective internal control over financial reporting in the future, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our Class B common stock may be negatively affected.
    As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control. Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, requires that we evaluate and determine the effectiveness of our internal control over financial reporting and, provide a management report on our internal control over financial reporting on an annual basis. If we have a material weakness in our internal control over financial reporting, we may not detect errors on a timely basis and our financial statements may be materially misstated. We will need to maintain and enhance these processes and controls as we grow, and we will require additional management and staff resources to do so. Additionally, even if we conclude our internal controls are effective for a given period, we may in the future identify one or more material weaknesses in our internal controls, in which case our management will be unable to conclude that our internal control over financial reporting is effective. As an accelerated filer, we are now required to include an attestation report from our independent registered public accounting firm on the effectiveness of our internal control over financial reporting annually. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may conclude that there are material weaknesses with respect to our internal controls or the level at which our internal controls are documented, designed, implemented or reviewed.
If we are unable to conclude that our internal control over financial reporting is effective, or if our auditors were to express an adverse opinion on the effectiveness of our internal control over financial reporting because we had one or more material weaknesses, investors could lose confidence in the accuracy and completeness of our financial disclosures, which could cause the price of our common stock to decline. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could have a material adverse effect on our reported operating results and harm our reputation. Internal control deficiencies could also result in a restatement of our financial results.
We may face risks related to securities litigation that could result in significant legal expenses and settlement or damage awards.

    We have been in the past and may in the future become subject to claims and litigation alleging violations of the securities laws or other related claims, which could harm our business and require us to incur significant costs. Future litigation may require significant attention from management and could result in significant legal expenses, settlement costs or damage awards that could have a material impact on our financial position, results of operations and cash flows.
The development and expansion of our business through acquisitions of other companies or technologies or other strategic transactions could divert our management’s attention, result in dilution to our stockholders and otherwise disrupt our operations and adversely affect our operating results.
    As we have done in the past, we may in the future seek to acquire or invest in businesses, products and services or technologies or enter into other strategic transactions that we believe could complement or expand our offerings, enhance our technical capabilities or otherwise offer growth opportunities. We have limited experience in acquiring other businesses and entering into strategic transactions. We may not achieve any of the anticipated benefits of any of these strategic transactions. The pursuit of potential acquisitions and other strategic transactions may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing suitable acquisitions and strategic alliances or transactions, whether or not they are consummated. We may not achieve any of the anticipated benefits or stated objectives from these or other strategic transactions we may enter into in the future.
    Factors affecting our ability to achieve the benefits of potential acquisitions or strategic alliances could include:

inability to integrate or benefit from acquired technologies or services or strategic collaborations or alliances in an efficient, effective or profitable manner;
unanticipated costs or liabilities associated with the acquisition or strategic transaction;
challenges in achieving strategic objectives, cost savings and other benefits expected from such transactions;
the lack of unilateral control over a strategic alliance and the risk that strategic partners have business goals and interests that are not aligned with ours;
delays, difficulties or unexpected costs in the integration, assimilation, implementation or modification of platforms, systems, functions, technologies and infrastructure to support the combined business or strategic alliance, as well as maintaining and integrating accounting systems and operations, uniform standards, controls (including internal accounting controls), procedures and policies;
difficulty converting the customers of the acquired business onto our platform and contract terms, including disparities in the revenue, licensing, support or professional services model of the acquired company;
diversion of management’s attention from other business concerns;
adverse effects to our existing business relationships with business partners and customers as a result of the acquisition or strategic transaction;
the potential loss of key employees;
the risk that we do not realize a satisfactory return on our investments;
diversion of resources that are needed in other parts of our business; and
use of substantial portions of our available cash to consummate the acquisition or strategic transaction.

    In addition, in prior acquisitions we completed, a significant portion of the purchase price was allocated to acquired goodwill and other intangible assets, which must be assessed for impairment at least annually. In the future, if our acquisitions do not yield expected returns, we may be required to take charges to our operating results based on this impairment assessment process, which could adversely affect our results of operations.

    Past acquisitions also resulted, and other acquisitions and strategic transactions could also result, in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our operating results. In addition, if an acquired business or other strategic transaction fails to meet our expectations, our operating results, business and financial position may suffer.
Changes in accounting principles may cause previously unanticipated fluctuations in our financial results, and the implementation of such changes may impact our ability to meet our financial reporting obligations.
    We prepare our financial statements in accordance with U.S. GAAP which are subject to interpretation or changes by the Financial Accounting Standards Board, or FASB, the SEC, and other various bodies formed to promulgate and interpret

Table of Contents


appropriate accounting principles. New accounting pronouncements and changes in accounting principles have occurred in the past and are expected to occur in the future which may have a significant effect on our financial results. Any difficulties in implementation of changes in accounting standards, including the ability to modify our accounting systems, could cause us to fail to meet our financial reporting obligations, which could result in regulatory discipline and harm investors’ confidence in us.
We incur significantly increased costs and devote substantial management time as a result of operating as a public company.
    As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company. For example, we are subject to the reporting requirements of the Exchange Act and are required to comply with the applicable requirements of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules and regulations subsequently implemented by the SEC and the New York Stock Exchange (the “NYSE”), including the establishment and maintenance of effective disclosure and financial controls, changes in corporate governance practices and required filing of annual, quarterly and current reports with respect to our business and operating results. Compliance with these requirements increases our legal and financial compliance costs and makes some activities more time consuming and costly. In addition, our management and other personnel divert attention from operational and other business matters to devote substantial time to these public company requirements. In particular, we incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act as an accelerated filer.

    Operating as a public company makes it more expensive for us to obtain director and officer liability insurance, and in the future we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. This could also make it more difficult for us to attract and retain qualified people to serve on our board of directors, our board committees or as executive officers.
Natural or man-made disasters and other similar events may significantly disrupt our business and negatively impact our results of operations and financial condition.
    Our offices and business operations may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, power outages, fires, floods, nuclear disasters, epidemics, pandemics or other health crises (including the current COVID-19 pandemic) and acts of terrorism or other criminal activities, which may render it difficult or impossible for us to operate our business for some period of time. For example, our headquarters is located in the San Francisco Bay Area, a region known for seismic activity. Any disruptions in our operations stemming from catastrophic events, including as related to the repair or replacement of our office, could negatively impact our business and results of operations and harm our reputation. In addition, we may not carry business insurance sufficient to compensate for losses that may occur. Any such losses or damages could have a material adverse effect on our business, results of operations and financial condition. In addition, the facilities of significant customers, health plans or major strategic partners may be harmed or rendered inoperable by such natural or man-made disasters, which may cause disruptions, difficulties or material adverse effects on our business.

Item 3. Legal Proceedings


From time to time, we may become subject to other legal proceedings, claims or litigation arising in the ordinary course of business. In addition, we may receive letters alleging infringement of patents or other intellectual property rights. If an unfavorable outcome were to occur in litigation, the impact could be material to our business, financial condition, cash flow, or results of operations, depending on the specific circumstances of the outcome.

COVID-19 Update.During the first generation care guidance solutions addressedquarter of 2020, a novel coronavirus disease (“COVID-19”) was declared a global pandemic by the needsWorld Health Organization and has resulted in the imposition of employees actively seeking carenumerous, unprecedented, national, and international measures to try to contain the virus, including travel bans and restrictions, shutdowns, quarantines, and shelter-in-place and social distancing orders. The spread of COVID-19 has significantly impacted the health and economic environment around the world and many governments have closed most public establishments, including restaurants, workplaces, and schools. Our health plan and corporate customers have been affected by the measures being put in place around the world, including the closure of offices, manufacturing sites, or managingcountry borders. A negative impact on our customers has caused some customers to request extended payment terms, delayed invoicing, higher discounts, lower renewal amounts, delayed buying decisions, or cancellations. Because we typically charge on a chronic conditionper-employee-per-month basis, and serve as the foundationsince some of our current care guidance offering.customers have reduced their workforces in response to the pandemic or otherwise, we may experience a corresponding reduction in revenue based on the renewal or audit date in the customer's contract.

The COVID-19 pandemic has caused us to modify our business practices, including, but not limited to: instituting a workforce reduction in May 2020 representing 13% of our headcount; implementing what was anticipated to be a temporary base salary reduction for executive management, directors, and other employees; curtailing or modifying employee travel; cancelling physical participation in meetings, events, and conferences; and moving to full remote work. We have subsequently implemented a return to work office protocol for certain employees located in our Utah Customer Center of Excellence. Our return to work plans for our San Francisco and Sunnyvale, California, offices remain subject to local health orders, and we have not yet been able to permanently re-open those offices. In 2015,November 2020, management, in consultation with the Company's board of directors, reinstated full salaries for those who were impacted by the salary reduction and restored the Board of Director’s cash compensation to its original levels, effective November 16, 2020.

Although the COVID-19 pandemic has been integrated into allcaused minor disruptions to our business operations, it has had a limited impact on our operating results thus far and these minor disruptions did not impact the delivery of our products to our customers or users. During these uncertain times, we have used our core technology to help users, customers, and rebrandedthe community navigate through the COVID-19 pandemic. The Castlight platform has supported our customers with COVID-19 education and communication of healthcare coverage changes, as well as analytics to identify and support vulnerable populations, and provided faster access to free ecosystem resources. We have provided our symptom checker and COVID-19 testing site finder to the community at no charge, and our testing site finder is being used to power some well-known public resources nationwide. In response to the COVID-19 pandemic, we made our behavioral health solution available to all customers on the Castlight Genius.Complete platform for no additional cost and launched the Working Well and Working Well for Higher Education solutions which are aimed at helping employers and academic institutions manage safe workforce re-entry and campus openings, respectively. In April 2017,addition, in the fourth quarter of 2020, we acquired Jiff, Inc. Jiffwere engaged by Boston Children’s Hospital to support their work with the Centers for Disease Control and Prevention ("CDC") to manage inventory and data related to COVID-19 vaccines. We will deliver a vaccine provider platform, which allows providers to enroll, log, and report daily inventory, daily reporting for the CDC, and display of COVID-19 vaccine information on VaccineFinder.org, a project of

Boston Children’s Hospital. The agreement with Boston Children's Hospital provides an enterprise health benefits platformfor payments to the Company totaling $8.5 million. We began the work in November 2020 and expect to complete the engagement in mid-2021.

Since the second quarter of 2020, we have seen that servesthe COVID-19 pandemic and its ensuing uncertainty on the general economy and our customers' businesses have led to elongated sales cycles and impacted our ability to sign on new customers. However, the potential duration, and extent of the impact, of the COVID-19 pandemic on our future liquidity and operational performance will depend on certain developments, including the duration and spread of the outbreak, the continued impact on our customers' operations and the global economy generally, and the continued impact to our sales and renewal cycles. We will continue to consider the potential impact of the COVID-19 pandemic on our business operations. The uncertainty of the COVID-19 pandemic affects our management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information become known.

For further discussion of the possible impact of the COVID-19 pandemic on our business, financial condition and results of operations, see the risk factor entitled "The COVID-19 pandemic has had a central hub for employee wellbeingmaterial adverse impact on the U.S. and employee benefit programs,global economies and iscould have a material adverse impact on our employees, suppliers, customers and users, which has negatively impacted our business, financial condition and results of operations and which could materially impact us in the foundation for our wellbeing offering.future" in Part I, Item 1A, “Risk Factors” of this Annual Report on Form 10-K.
Key Factors Affecting Our Performance


Sales of New and Additional Products. Our revenue growth rate and long-term profitability are affected by our ability to sell new and additional products to new and existing customers, directly and through our channel partners. Additionally, we believe that there is a significant opportunity to sell subscriptions to add-on products as our customers become more familiar with our offering and seek to address additional needs.


Renewals of Customer Contracts. We believe that our ability to retain our customers and expand their subscription revenue growth over time will be an indicator of the stability of our revenue base and the long-term value of our customer relationships.

Channel Partnerships. We have relationships with channel partners including Anthem, which complement our direct sales capabilities. These relationships allow deeper penetration into our market and enable us to promote our health benefits platform and products to create customer cross-sell opportunities.

Ecosystem Partnerships: . We have relationships with digital health partners that integrate with our platform to provide a more streamlined experience for our customers and users. We also have over 1,000many third-party benefit solutions integrated with our products to enable simplified procurement and effortless access to these programs to our users. We believe these partnerships enable a single user experience that is essential to drive engagement and increase user satisfaction.


Implementation Timelines. Our ability to convert backlog into revenue and improve our gross margin depends on how quickly we complete customer implementations. Our implementation timelines vary from customer to customer based on the source and condition of the data we receive from third parties, the configurations that we agree to provide and the size of the customer. Our implementation timelines for our productscore product offerings are typically three to 12 months after entering into an agreement with a customer.


Professional Services Model. We believe our professional services capabilities support the adoption of our subscription offerings. As a result, our sales efforts have been focused primarily on our subscription offering, rather than the profitability of our professional services business. Our professional services are generally priced on a fixed-fee basis and the costs incurred to complete these services, which consist mainly of personnel-related costs, have been greater than the amount charged to the customer. We also do not have standalone value forconcluded that our implementation services are not distinct for accounting purposes. Accordingly, we recognize implementation services revenue in the same manner as the associated subscription revenue. Prior to launching an individual customer, we incur significant costs associated with implementation activities,revenue, which we record as cost of revenue. Since we do not recognize significant revenues from an individual customer until it launches, we generateis recognized on a negative gross margin atstraight-line basis, ratably over the customer level during the implementation period.contract term.


Seasonality.We have historically observed seasonality related to employee benefits cycles as a significantly higher proportion of our customers enter into new subscription agreements with us in the second half of the year, compared to the first half of the year. As we continue to leverage our channel relationships and expand our business, there is no assurance this seasonality will continue. The impact from any seasonality in our new customer agreements is not immediately apparent in our revenue because we do not begin recognizing revenue from new customer agreements until we have implemented our offering, based on the implementation timelines discussed above.

Revenue recognized in any quarter is primarily from customer agreements entered into in prior quarters. In addition, the mix of customers paying monthly, quarterly, or annually varies from quarter to quarter and impacts our deferred revenue balance. As a result of variability in our billing and implementation timelines, the deferred revenue balance does not represent the total value of our customer contracts, nor do changes in deferred revenue serve as a reliable indicator of our future subscription revenue.
   
Key Business Metrics
We review a number of operating metrics, including the following key metrics, to evaluate our business, measure our performance, identify trends affecting our business, and make strategic decisions.


Signed Annual Recurring Revenue (“ARR”)
As of
December 31, 2020December 31, 2019

Signed Annual Recurring Revenue$163.2
 $121.6


Revenue recognized in any quarter is largely derived from customer agreements signed in prior quarters. Accordingly, management measures sales performance and forecasts future subscription revenue based on signed Annual Recurring Revenue. ARR is a forward-looking metric based on contractual terms in existence as of the applicable ARR measurement date and is subject to change resulting from a number of factors including, but not limited to, addition of new customers, changes in user counts, terminations or non-renewals, renewal terms as well as upsells and cross-sells. As discussed above, we begin

recognizing revenue from new customer agreements when we have implemented our offering, which can take from approximately three to 12 months after entering into an agreement with a customer.


ARR represents the annualized value of subscription revenue under contract with customers at the end of a quarter, which we refer to for this purpose as a measurement date. To calculate ARR, we first calculate the annualized subscription value for each signed customer (whether implemented or not), as of the applicable measurement date, by multiplying the monthly contract value of the subscription services under contract by 12. We exclude from this calculation any customers that have provided us with formal notice of termination or non-renewal as of the measurement date. ARR does not take into account the (i) potential for customers to terminate, or decline to renew, their agreements with us, (ii) achievement of non-recurring or yet-to-be-earned performance guarantees, (iii) one-time engagement bonuses included within our customer contracts or (iv) revenues related to professional services, such as implementation and communications services. ARR is not determined in reference to GAAP.


Our ARR at December 31, 20172020 was $163.2$126.7 million, compared to $121.6$147.0 million at December 31, 2016,2019, representing an increasea decrease of approximately 34.2%13.8%, primarily attributable to churn, partially offset by new customers and cross-sales of Jiff products into the legacy Castlight customer base.renewals.

Annual Net Dollar Retention Rate83 %94 %
 Year Ended December 31,

Annual Net Dollar Retention Rate104% 94%

We assess our performance on customer retention by measuring our Annual Net Dollar Retention Rate.rate. We believe that our ability to retain our customers and expand their subscription revenue growth over time will be an indicator of the stability of our revenue base and the long-term value of our customer relationships. Our NDR provides a measurement of our ability to increase revenue across our existing customer base through expansion of our additional products to existing customers, increases in user countcounts for existing customers and customer renewals, as offset by terminations or pricing changes. The addition or loss of a significant customer or customers during the calendar year can have a significant impact on NDR. We calculate NDR for a given period as the aggregate annualized subscription contract value as of the last day of that year from those customers that were also customers as of the last day of the prior year, divided by the aggregate annualized subscription contract value from all customers as of the last day of the prior year. In calculating NDR, we exclude one-time fees. NDR does not include subscriptions by new customers contracted since the end of the most recently completed year. We observed an annual net dollar retention rate of 104% and 94% for our signed customer base,83% for the yearsyear ended December 31, 20172020 for customers that were signed as of

Revenue

We generate revenue from subscription fees from customers for access to the products they select, including basic customer service support.select. We also earn revenue from professional services primarily related to the implementation of our offering, including extensive communications support to drive adoption by our customers’ employees and their dependents, products sold through our online market placemarketplace and add-on subscription products made available from our other ecosystem partners.
Historically, we have derived a substantial majority of our subscription revenue from our legacy core Castlight platform (now marketed as “Care Guidance Navigator”). Our subscription fees are based primarily on the number of employees and adult dependentsusers that employers identify as eligible to use our offering, which typically includes all of our customers’ employees and adult dependents that receive health benefits.
Typically, we recognize subscription fees on a straight-line basis ratably over the contract term beginning when our products are implemented and ready for launch, which is based on the implementation timelines discussed above.launch. Our customer agreements generally have a term of three years. We generally invoice our customers in advance on a monthly, quarterly or annual basis. Amounts that have been invoiced are initially recorded as deferred revenue. Amounts that have not been invoiced

where revenue has been recognized are not reflected as contract assets and recorded as accounts receivable and other in our consolidated financial statements. We generally invoice our implementation services upon contract signing on a fixed-fee basis, which is generally when we commence work.

As a result of variability in our billing terms, the deferred revenue balance does not represent the total value of our customer contracts, nor do changes in deferred revenue serve as a reliable indicator of our future subscription revenue in a given period.

CostCosts of Revenue

Cost of revenue consists of the cost of subscription revenue and cost of professional services and other revenue.

Cost of subscription revenue primarily consists of data fees, employee-related expenses (including salaries, bonuses, benefits and stock-based compensation), hosting costs of our cloud-based subscription service, cost of subcontractors, expenses for service delivery (which includes call center support), allocated overhead, amortization of internal-use software, and depreciation of certain owned computer equipment and software.software, amortization of certain intangibles, and allocated overhead.

Cost of professional services and other revenue consists primarily of employee-related expenses (including salaries, bonuses, benefits and stock-based compensation) associated with these services, the cost of subcontractors, and travel costs and allocated overhead. The time and costs of our customer implementations vary based on the source and condition of the data we receive from third parties, the configurations that we agree to provide and the size of the customer.

Our cost of subscription revenue is expensed as we incur the costs. However,The cost of professional services and other revenue, to the related revenue isextent they are incurred and are directly attributable to fulfillment of performance obligations under a customer contract, are deferred until our products are ready for use by the customer and then recognized as revenue ratablyamortized over the related contract term. Therefore, we expense the cost incurred to provide our products and services prior to the recognitionbenefit period of the corresponding revenue.five years.

Operating Expenses

Operating expenses consist of sales and marketing, research and development and general and administrative expenses.
Sales and Marketing. Sales and marketing expenses consist primarily of employee-related expenses (including salaries, sales commissions and bonuses, benefits and stock-based compensation), travel-related expenses, marketing programs, amortization of certain intangibles and allocated overhead. CommissionsAll commissions earned by our sales force and brokerthird-party referral fees that can be associated specifically with the non-cancellable portion of a subscription contract are deferred and amortized generally over the non-cancellable period. Accordingly, commission expense can be materially impacted by changes in the termination provisionsa period of customer contracts that we execute in a given period compared with previous periods.five years.


Research and Development. Research and development expenses consist primarily of employee-related expenses (including salaries, bonuses, benefits and stock-based compensation), costs associated with subcontractors and allocated overhead.

New customer launches, in 2017 accounted for $17.4 million of the increase. Jiff, which we acquired on April 3, 2017, accounted for $10.9 million of the increase. Full year 2017 revenue from customers launched in 2016 accounted for $10.1 million of the increase. These increases were partially offset by customer terminations. Our launched customer base grew more than 12% year over year.

Professional services and other revenue decreased primarily due to lower implementation activities, partially offset by revenue from Boston Children’s Hospital.

Cost of subscription revenue increased $11.9$0.9 million or 73%3%, primarily driven by the acquisitiondue to an increase of Jiff in the second quarter of 2017. The acquisition drove a $6.1$2.1 million increase in employee-related expenses, $2.3partially offset by decreases of $0.8 million increase related to the amortization of acquired intangibles, $1.6hosting costs and $0.3 million increase in data and hosting services and $1.0 million in third party service fees, which was a result of the rapid ramp up of our call center directly attributable to a growth in our customer base, increased usage, and internal operational investments.facilities costs.
Cost of professional services revenue increased $0.7decreased $8.0 million or 4%, primarily as a result of a $0.7 million increase in use of temporary resources to fulfill our obligations pertaining to customer launches.
Gross margin for the year ended December 31, 2017 decreased primarily due to revenue growth of 29% compared to a 37% growth in associated costs. We expect an initial decline in gross margin due to the acquisition of Jiff, as the Jiff functionality is in an early stage of launching clients during their rapid growth phase. Over time, we expect to see favorable overall gross margin trends as we continue to increase the number of launched customers in relation to customers in the implementation phase.

General and administrative expense increased $2.6 million or 11%, primarily attributable to a $2.9 million increase in litigation expenses related to a litigation settlement in 2016 and $1.6 million increase for acquisition costs, related to the ongoing acquisition of Jiff, Inc. The increase was offset by a $1.1 million decrease in contractor expense as we gained the benefit of our systems and infrastructure investments and a $0.7 million decrease in recruiting expense as a result of a decrease in hiring efforts due to the reduction in workforce in the second quarterresponse to COVID-19, $0.5 million of 2016.legal costs and $0.5 million of third-party contractor and professional services fees, partially offset by severance-related costs of $0.5 million and an increase of $0.4 million of facilities costs.


Income tax benefit

The effective tax rate for 2017, 2016 and 2015 was (8.6)%, 0.0% and 0.0%, respectively. As a result of the acquisition of Jiff in April 2017, the Company recorded a tax benefit of $5.2 million as a discrete item in the second quarter of 2017. This tax benefit is a result of the partial release of its existing valuation allowance since the acquired deferred tax liabilities from Jiff will provide a source of income for the Company to realize a portion of its deferred tax assets, for which a valuation allowance is no longer needed. The Company's effective tax rate for 2016 and 2015 was primarily a result of the tax loss for the year and the change in valuation allowance.

On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act of 2017 (the “Act”) into law. The new legislation decreases the U.S. corporate federal income tax rate from 35% to 21% effective January 1, 2018. The Act also includes a number of other provisions including the elimination of loss carrybacks and limitations on the use of future losses and repeal of the Alternative Minimum Tax regime. The Company has calculated its best estimate of the impact of the Tax Act in its year end income tax provision in accordance with its understanding of the Tax Act and guidance available as of the date of this filing. The provisional amount related to the re-measurement of certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future was a net decrease related to deferred tax assets and deferred tax liabilities of $54.6 million, with a corresponding offsetting change in valuation allowance of $54.6 million for the year ended December 31, 2017.
On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, the Company has determined that the adjustment to deferred taxes was a provisional amount and a reasonable estimate at December 31, 2017. The determination of the benefit from income taxes requires complex estimations, significant judgments and significant knowledge and experience concerning the applicable tax laws. Given that the Company is still in the transition period for the accounting for income tax effects of the Act, the current assessment on deferred tax assets and liabilities is based on the currently available information and guidance. If in the future any element of the tax reform changes the related accounting guidance for income tax, it could affect the Company’s income tax position, and the Company may need to adjust the benefit from (provision for) income taxes accordingly.

As of December 31, 2017,2020, our principal sources of liquidity were cash and cash equivalents and marketable securities totaling $93.3$49.2 million, which were held for working capital purposes. Our cash cash equivalents and marketable securities are comprised primarily of U.S. agency obligations, U.S. treasury securities and money market funds.
Since our inception, we have financed our operations primarily through sales of equity securities and to a lesser extent, paymentsreceipts from our customers. We believe that our existing cash and cash equivalents and marketable securities will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. Our future capital requirements will depend on many factors including our growth rate, new customer acquisitions, subscription renewal activity, operation and integration of the Jiff business, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the introduction of new and enhanced servicesservice offerings and the continuing market acceptance of our cloud-based subscription services. Although we currently are not a party to any agreement and do not have any understanding with any third parties with respect to potential investments in, or acquisitions of, businesses or technologies, we may in the future enter into these types of arrangements.
We process certain vendor payments using a financial institution's credit card program, which carries a $20.0 million limit. We pay the financial institution monthly based on the terms of the credit card program.
On April 3, 2017, Castlight, JiffMay 5, 2020, we entered into the Third Amended and Restated Loan and Security Agreement (the "Amended Loan Agreement") with Silicon Valley Bank (the "Bank"). Under the Amended Loan Agreement, the Bank agreed to refinance the existing term loan facility owed by Jiff to the Silicon Valley Bank. The loan agreement provides for an approximately $5.6 million term loan and up toextend a $25$25.0 million revolving credit facility.facility (the “Revolving Line”) to us. We may request borrowings under the Revolving Line prior to May 4, 2023, on which date the Revolving Line terminates. Refer to Note 8 –Debt9 – Debt to the consolidated financial statements for further information on debt.
We may be required to seek additional equity or debt financing.financing in the future. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition would be adversely affected.
Operating Activities
For the year ended December 31, 2017, cash used in operating activities was $23.5 million. The negative cash flows resulted primarily from our net loss of $55.6 million, which include $37.4 million in non-cash adjustments. The non-cash adjustments to net loss included stock-based compensation expense of $24.6 million, amortization of deferred commissions of $12.5 million, depreciation and amortization of $6.6 million, and expense related to the expiration of the SAP Warrant of $1.1 million, partially offset by the release of the deferred tax valuation allowance of $5.2 million, the gain on the sale of additional equity would result in additional dilution to our investmentstockholders. The incurrence of debt financing would result in Lyra Health ("Lyra") of $1.4 milliondebt service obligations and the change in the fair value of the contingent consideration liability of $0.7 million. Uses of working capital included an increase in deferred commissions of $9.8 million due to non-cancellable portion of new contracts signed in the year, an increase in accounts receivable of $2.5 million driven by 25% increase in billings year over yearinstruments governing such debt could provide for operating and the timing of billings and collections, and a decrease in deferred revenue of $1.6 million. These uses of cash were partially offset by sources of working capital which included an increase of $3.5 million in accrued expenses and other liabilities, an increase of $2.7 million in accrued compensation due to higher bonus expense resulting from growth in employee count, and a decrease of $1.6 million in prepaid expenses and other assets primarily due to reimbursement of tenant allowances and security deposits.

For the year ended December 31, 2016, cash used in operating activities was $37.0 million. The negative cash flows resulted primarily from our net loss of $58.5 million, adjusted for $30.7 million in non-cash expensesfinancing covenants that primarily included stock-based compensation of $22.0 million and amortization of deferred commissions of $5.1 million, depreciation and

Investing Activities

Cash provided by investing activities for the years ended December 31, 2017, 2016, and 2015 was $34.6 million, $46.6 million, and $55.7 million, respectively. The increase in cash provided was primarily the result of the timing of purchases, sales and maturities of marketable securities, the net result of which was $33.9 million, $48.3 million, and $65.2 million for the years ended December 31, 2017, 2016 and 2015, respectively. During 2017, cash provided by investing activities also included cash proceeds of $5.5 million from the sale of our investment in Lyra. These increases were partially offset by purchases of property and equipment, which were $2.5 million, $1.7 million and $5.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. We also paid $2.3 million in transaction costs, net of cash acquired, during 2017 to acquire Jiff. During 2015, cash used in investing activities included a total investment of $4.1 million in Lyra. See Note 9–Related Party Transactions and Variable Interest Entity for additional information on the Lyra transactions.

Financing Activities

For the year ended December 31, 2017, financing activities provided $1.6 million, primarily from cash proceeds resulting from issuance of stock under our equity incentive plans. For the year ended December 31, 2016, financing activities provided $20.1 million, primarily from transactions with SAP Technologies, Inc. and cash proceeds resulting from issuance of stock under our equity incentive plans. See Note 13–Stockholders' Equity under the caption "Transactions with SAP Technologies, Inc." for additional information. For the year ended December 31, 2015, financing activities provided $3.9 million, primarily from cash proceeds resulting from issuance of stock under our equity incentive plans.
Backlog
We have generally signed multiple-year subscription contracts for our cloud-based subscription services. The timing of our invoices to the customer is a negotiated term and thus varies among our subscription contracts. For multiple-year agreements, it is common to invoice an initial amount at contract signing for implementation work that is deferred followed by subsequent annual, quarterly or monthly invoices, beginning when we launch a customer, which is when our product is implemented and usable by the customer. At any point in the contract term, there can be amounts that we are not yet contractually able to invoice. Until such time as these amounts are invoiced, they are not recorded in revenue, deferred revenue or elsewhere in our consolidated financial statements and are considered by us to be backlog. The amount of our total backlog for subscription and professional services contracts, which we define as including both cancellable and non-cancellable portions of our customer agreements that we have not yet billed, was approximately $336.0 million as of December 31, 2017 and $197.6 million as of December 31, 2016. Our total backlog does not take into account contractual provisions that give customers a right to terminate their agreements with us. The amount of our backlog for subscription and professional services contracts was approximately $136.8 million at December 31, 2017 and $90.5 million as of December 31, 2016, respectively, for the non-cancellable portions of our customer agreements that we have not yet billed. We fulfill backlog associated with a customer contract when the customer implementation process is complete. Our implementation timelines can vary between three and 12 months, based on the source and condition of the data we receive from third parties, the configurations that we agree to provide and the size of the customer and therefore, are subject to significant uncertainties, which can have a material impact on our total backlog and non-cancellable backlog that we fulfill in the current year.

Investing Activities

Cash provided by investing activities was $12.8 million for the year ended December 31, 2020. Cash provided by investing activities was attributable to $16.4 million of net proceeds from the sale and maturities of marketable securities, net of purchases, partially offset by $3.6 million of purchases of property and equipment. Cash used in investing activities was $6.8 million for the year ended December 31, 2019. Cash used in investing activities was attributable to $4.8 million of purchases net of maturities of marketable securities and $2.0 million of purchases of property and equipment.

Financing Activities

For the year ended December 31, 2020, cash used in financing activities was $1.2 million. Cash used in financing activities was due to principal payments on long-term debt of $1.9 million, partially offset by cash proceeds from exercises of employee stock options of $0.3 million and ESPP offering of $0.4 million. For the year ended December 31, 2019, cash provided by financing activities was $1.2 million, primarily from cash proceeds from exercises of employee stock options of $3.1 million, partially offset by principal payments on long-term debt of $1.9 million.
Backlog
Backlog is equivalent to our remaining performance obligations and represents our non-cancellable contractual commitments for which service will be performed. Remaining performance obligations are defined as deferred revenue and amount yet to be billed for the non-cancelable portion of contracts. Backlog generally increases with bookings and converts into revenue as performance obligations are fulfilled.
The amount of our backlog relative to the total valuefor subscription and professional services contracts was approximately $163.0 million and $253.7 million as of our contracts will change from period to period for several reasons, including the amount of cash collected early in the contract term, the specific timingDecember 31, 2020 and duration of large customer subscription agreements, varying invoicing cycles of subscription agreements, potential customer upsells dependent on our customer agreements, the specific timing of customer renewals and changes in customer financial circumstances. Accordingly, we believe that fluctuations in our backlog may not be a reliable indicator of our future revenue.2019, respectively.
Contractual Obligations and Commitments

We are therefore not exposed to the financing, liquidity, market or credit risk that could arise if we had engaged in those types of relationships.December 31, 2020.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

We believe that certain of our significant accounting policies, which are described in Note 2–Summary of2 Accounting Standards and Significant Accounting Policies to our consolidated financial statements, involve a greater degree of judgment and complexity. Accordingly, these are the policies that we believe are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations.
Revenue Recognition
We derive our revenue from sales of cloud-based subscription service and professional services contracts. Our cloud-based subscription service contracts are generally three years in length.
Our cloud-based subscription service contracts do not provide customers with the right to take possession of the software supporting the cloud-based service and, as a result, are accounted for as service contracts.
We commence revenue recognition for our cloud-based subscription service and professional services when all of the following criteria are met:
there is persuasive evidence of an arrangement;
the service has been provided to the customer;
collection of the fees is reasonably assured; and
the amount of fees to be paid by the customer is fixed or determinable.
Our subscription and professional service arrangements do not contain refund provisions for fees earned related to services performed. We do, however, have commitments under service-level agreements, as discussed under "Warranties and Indemnification" in the Notes to consolidated financial statements.
Subscription Revenue. Subscription revenue recognition commences on the date that our cloud-based service is made available to the customer, which is considered the launch date, provided all of the other criteria described above are met. Revenue is typically recognized on a straight-line basis.
Some of our cloud-based subscription arrangements include performance incentives that are generally based upon employee engagement. Fees for performance incentives are considered contingent revenue, and are recognized over the remaining term of the related subscription arrangement commencing at the time they are earned.
Professional Services and Other Revenue. Professional services and other revenue is comprised of implementation services and communication services related to our cloud-based subscription service. Nearly all of our professional services are sold on a fixed-fee basis. We do not have standalone value for our implementation services. Accordingly, we recognize implementation services revenue in the same manner as the associated cloud-based subscription service, beginning on the launch date, provided all other criteria described above have been met. Communication services revenue is recognized over the contractual term, generally one year, commencing when the revenue recognition criteria have been met. Revenue from products sold through our online market place and add-on subscription products made available from other ecosystem partners are recognized on a net basis principally because we are not the primary obligor to the end-customers.
Multiple Deliverable Arrangements. To date, we have generated substantially all our revenue from multiple deliverable arrangements consisting of multi-year cloud-based subscription services and professional services, including implementation services and communication services. For arrangements with multiple deliverables, we evaluate whether the individual deliverables qualify as separate units of accounting. In order to treat deliverables in a multiple deliverable arrangement as separate units of accounting, the deliverables must have standalone value upon delivery. If the deliverables have standalone value upon delivery, we account for each deliverable separately and revenue is recognized for the respective deliverables as they are delivered. If one or more of the deliverables do not have standalone value upon delivery, the deliverables that do not have standalone value are generally combined with our cloud-based subscription service, and revenue for the combined unit is recognized over the remaining term of the cloud-based subscription service.
Our deliverables have standalone value if we or any other vendor sells a similar service separately. We have concluded that we have standalone value for our cloud-based subscription service as we sell these services separately through renewals and for our communication services as other vendors sell similar services separately. Conversely, we have concluded that our

Revenue Recognition
We derive our revenue primarily from contracts with customers for subscription services and professional services. Revenues are recognized when control of these services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. Revenues do not include sales taxes.
We determine revenue recognition through the following steps:

Identification of the contract, or contracts, with a customer;
Identification of the performance obligations in the contract;
Determination of the transaction price;
Allocation of the transaction price to the performance obligations in the contract; and
Recognition of revenue when, or as, the Company satisfies a performance obligation.

Subscription Revenue.Subscription revenue recognition commences on the date that our subscription services are made available to the customer, which we consider to be the launch date, and subscription revenue is generally recognized over the contract term. Subscription contracts are generally three years in length and certain contracts include termination provisions.

Some of our subscription contracts include performance incentives that are generally based on engagement. Additionally, some of our subscription contracts include audit provisions. We consider fees related to performance incentives and audit provisions to be variable consideration. We estimate variable consideration at the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance as well as other information available to us. We reassess estimates related to variable consideration each reporting period and records adjustments when appropriate.

Professional Services and Other Revenue. Professional services and other revenue is primarily comprised of implementation services dorelated to our subscription service. Nearly all of our professional services are sold on a fixed-fee basis.

Professional services and other revenue also includes revenue from products sold through our online marketplace and add-on subscription services made available from other ecosystem partners. These revenues are recognized on a net basis primarily because we act as an agent in these contracts.

Contracts with Multiple Performance Obligations. Most of our contracts have multiple promised services consisting of subscription services and professional services, including implementation services. For contracts with multiple promised services, we evaluate whether the promised services are distinct. If the promised services are distinct, revenue is recognized for the respective performance obligation separately. If one or more of the promised services are not distinct, the promised services that are not distinct are combined with our subscription service, and revenue for the respective combined performance obligation is recognized over the term of the subscription service.

We have standalone value, as we and others doconcluded that our implementation services are not yet selldistinct, primarily because these services separately.are not capable of being distinct as the customer cannot benefit from the implementation services on their own. Accordingly, we consider the separate units of accountingperformance obligations in ourcontracts with multiple deliverable arrangementspromised services to be the communication services and a combined deliverableperformance obligation comprised of cloud-based subscription services and implementation services.

Deferred revenue consists of professional services and cloud-based subscription services that have been billed in advance of revenue being recognized. We invoice our customers for each unit of accounting. Vendor-specific objective evidence, or VSOE, of selling price,cloud-based subscription services based on the price atterms of the contract, which can be annual, quarterly or monthly installments. Deferred revenue that is anticipated to be recognized during the itemsucceeding 12-month period is regularly sold by the vendor on a standalone basis, should be used if it exists. If VSOE of selling price is not available, third-party evidence, or TPE, of selling price is used to establish the selling price if it exists. If TPE does not exist, we estimate the best estimated selling price, or BESP. VSOE does not currently exist for any of our deliverables. Additionally, we do not believe TPE is a practical alternative due to differences in our cloud-based subscription service compared to that of other partiesrecorded as current deferred revenue, and the availability of relevant third-party pricing information for our cloud-based subscription service and our other services. Accordingly, for arrangements with multiple deliverables that can be separated into different units of accounting, we allocate the arrangement fee to the separate units of accounting based on our BESP. The amount of arrangement fee allocatedremaining portion is limited by contingent revenue, if any.
We determine BESP for our deliverables by considering our overall pricing objectives and market conditions. This includes evaluating our pricing practices, our target prices, the size of our transactions, historical sales and our go-to-market strategy. The determination of BESP is made through consultation with and approval by management. For financial statement presentation purposes, we allocate the fees from our combined units of accounting to subscription and professional services based upon their relative selling price.

Goodwill
We review goodwill for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. We have elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of the Company’s single reporting unit is less than its carrying amount. If it is determined that it is more likely than not that its fair value is less than its carrying amount, step 1 of the goodwillwe perform a quantitative impairment test will be performed,of goodwill, in which the fair value of our single reporting unit is compared to its carrying value. Any excess of the goodwill carrying amount over the fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value. As of December 31, 2017, no impairment of goodwill has been identified.Refer to Note 5 – Goodwill and Intangible Assets to the consolidated financial statements for further information on goodwill.
Intangible Assets
Acquired finite-lived intangible assets are amortized over their estimated useful lives. We evaluate the recoverability of our intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of intangible assets is not recoverable, the carrying amount of such assets is reduced to fair value. We have not recorded any such impairment charges.
Deferred Commissions
Deferred commissions are the incremental costs that are directly associated with the non-cancellable portion of cloud-based subscription serviceincurred to obtain contracts with customers and consist primarily of sales commissions paid to our direct sales force and channel partners. The commissions for initial contracts are deferred and amortized on a straight-line basis over a period of benefit that we determined typically to be five years. We determined the non-cancellable termsperiod of benefit by taking into consideration the expected life of its subscription contracts, the expected life of the related contracts.technology underlying its subscription services and other factors. The deferred commission amounts are recoverable through theour future revenue streams under the non-cancellable customer contracts.revenues. Amortization of deferred commissions is included in sales and marketing expense in the accompanying consolidated statements of operations. All costs deferred are reviewed for impairment quarterly.


Deferred Professional Service Costs

Deferred professional services costs are the direct costs incurred to fulfill subscription contracts that occur prior to the launch of our subscription services. Professional service costs, which primarily consist of employee related expenses attributable to launch activities, are deferred and amortized on a straight-line basis over a period of benefit that we determined typically to be five years for the same reasons as described in the deferred commissions disclosure above. Deferred professional service costs are recoverable through future revenues. Amortization of deferred professional service costs is included in cost of professional services and other revenue in the accompanying consolidated statements of operations. All costs deferred are reviewed for impairment quarterly.

Stock-Based Compensation
Compensation expense relatedAll stock-based compensation to stock-based transactions, including employee, consultant and non-employee director stock option awards,employees is measured based on the grant-date fair value of the awards and recognized in the financialCompany's consolidated statements based on fair value.of operations over the period during which the employee is required to perform services in exchange for the award (generally the vesting period of the award). The options assumed and awarded in connection withCompany accounts for forfeitures as they occur. The Company estimates the acquisition of Jiff were valued using the Monte Carlo simulation model. The fair value of each option award,all other thanstock options and stock purchase rights under the options assumed and awarded in connection with the Jiff acquisition, is estimated on the grant dateemployee stock purchase plan using the Black-Scholes option-pricingoption valuation model. The stock-based compensation expense, net of forfeitures, is recognized using a straight-line basis over the requisite service periods of the awards, which is generally four years. For restricted stock units, fair value is based on the closing price of ourthe Company's Class B common stock on the grant date. Compensation expense is recognized over the vesting period of the applicable award using the straight-line method. For awards with performance based and service vesting conditions, compensation costexpense is recognized over the requisite service period if it is probable that the performanceperformance-based condition will be satisfied based on the accelerated attribution method. For awards with market based and service vesting conditions, compensation expense is recognized over the requisite service period using the accelerated attribution method.

Our option-pricing model requires the input of highly subjective assumptions, including the fair value of the underlying common stock, the expected term of the option, the expected volatility of the price of our common stock, risk-free interest rates and the expected dividend yield of our common stock. The assumptions used in our option-pricing model represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our stock-based compensation expense could be materially different in the future.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Sensitivity
We had cash, cash equivalents and marketable securities totaling $93.3 million at December 31, 2017 and $114.6 million as of December 31, 2016. This amount was invested primarily in U.S. agency obligations, U.S. treasury securities and money market funds. The cash, cash equivalents and short-term marketable securities are held for working capital purposes. Our investments are made for capital preservation purposes. WeAs a smaller reporting company, SEC rules do not enter into investments for trading or speculative purposes. All our investments are denominated in U.S. dollars.require us to provide the information required by this Item.
Our cash equivalents and our portfolio of marketable securities are subject to market risk due to changes in interest rates. Fixed rate securities may have their market value adversely affected due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. However, because we classify our marketable securities as “available for sale”, no gains or losses are recognized due to changes in interest rates unless such securities are sold prior to maturity or declines in fair value are determined to be other-than-temporary. Our fixed-income portfolio is subject to interest rate risk.

An immediate increase of 100-basis points in interest rates would have resulted in a $0.1 million market value reduction in our investment portfolio as of December 31, 2017. All of our investments earn less than 100-basis points and as a result, an immediate decrease of 100-basis points in interest rates would have increased the market value by $0.1 million as of December 31, 2017. This estimate is based on a sensitivity model that measures market value changes when changes in interest rates occur. Fluctuations in the value of our investment securities caused by a change in interest rates (gains or losses on the carrying value) are recorded in other comprehensive income, and are realized only if we sell the underlying securities.

We also have interest rate exposure as a result of our loan agreement, which provides a term loan and revolving credit facility, as described in Note 8–Debt to the consolidated financial statements. We currently do not hedge this risk. At December 31, 2017, we had $5.6 million of borrowings outstanding under the term loan and no borrowings outstanding under the revolver. Borrowings outstanding under the term loan and revolver are subject to variable interest rates based on the prime rate as published in the money rates section of The Wall Street Journal. Changes in the prime ratewill affect the interest on borrowings under the loan agreement. However, a 50-basis point increase in the interest rate on the term loan would not materially increase interest expense during 2017.

To the stockholdersStockholders and the Board of Directors of Castlight Health, Inc.


Opinion on the Financial Statements


We have audited the accompanying consolidated balance sheets of Castlight Health, Inc. (the Company) as of December 31, 20172020 and 2016,2019 and the related consolidated statements of operations, comprehensive loss, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2017,2020 and the related notes (collectively referred to as the "financial statements"“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as ofat December 31, 20172020 and 2016,2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2020, in conformity with U.S. generally accepted accounting principles.


We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 24, 2021 expressed an unqualified opinion thereon.

Basis for Opinion


These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company'sCompany’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB)PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.


We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures includeincluded examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Goodwill impairment
Description of the matterAs of December 31, 2020, the Company’s goodwill balance was $41.5 million. As discussed in Note 2 to the consolidated financial statements, the Company reviews goodwill for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. As further discussed in Note 5, in the first quarter of 2020, the Company determined that the significant decline in the U.S. economy as a result of the COVID-19 pandemic, together with the decline in the Company’s stock price, constituted a triggering event, which required the Company to perform an interim impairment analysis related to its goodwill. The result of this analysis indicated that the fair value of the Company’s only reporting unit, which was determined using the income approach, exceeded the carrying value by approximately $50.3 million. Accordingly, the Company recorded a goodwill impairment for this amount.

Auditing the Company’s goodwill impairment analysis was challenging due to the significant judgments required to assess the implied control premium and to evaluate the appropriateness of the assumptions used by the Company to determine the fair value of its single reporting unit using the income approach, including future estimated revenues and expenses and discounts rates.
How we addressed the matter in our auditWe obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's process to review goodwill for impairment. For example, we tested controls over Management’s review of the valuation model and the significant assumptions, as discussed above, used to determine fair value.

Our procedures included, among others, with the support of our valuation specialist, assessing the Company’s fair value methodology and reconciling the market capitalization of the Company to the fair value to validate the reasonableness of the implied control premium. We also tested the significant assumptions discussed above as well as the underlying data used by the Company in its analysis. We compared the significant assumptions used by the Company to current industry and economic trends as well as to forecasted and historical operating results. Additionally, we performed sensitivity analyses of significant assumptions to evaluate the changes in the fair value of the reporting unit that would result from changes in the assumptions.
Revenue recognition
Description of the matterAs described in Note 2 to the consolidated financial statements, the Company’s revenues are derived primarily from contracts with customers for subscription services and professional services. Most of the Company’s contracts have multiple promised services consisting of subscription services and professional services. For these contracts, the Company evaluates whether the promised services are distinct. If the promised services are distinct, revenue is recognized for the respective performance obligation separately. If one or more of the promised services are not distinct, the promised services that are not distinct are combined with the Company's subscription service, and revenue for the respective combined performance obligation is recognized over the term of the subscription service. The transaction price for arrangements with multiple performance obligations is allocated to the separate performance obligations based on their standalone selling prices.

Auditing the Company's determination of distinct performance obligations and the allocation of the transaction price to the performance obligations was challenging. Judgment was required to determine whether the subscription services and professional services, specifically implementation services, should be accounted for as distinct performance obligations or combined into a single performance obligation and the related determination of the standalone selling prices for each distinct performance obligation.
How we addressed the matter in our auditWe obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's process to identify distinct performance obligations and allocate the transaction price, including the underlying assumptions related to the standalone selling prices.

Our procedures included, among others, selecting a sample of contracts, including the Anthem enterprise license agreement, and evaluating whether the Company applied the appropriate revenue recognition. As part of our procedures, we evaluated the assessment of distinct performance obligations and the accuracy and completeness of the underlying data used in the Company’s determination of the standalone selling prices.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Castlight Health, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Castlight Health, Inc’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Castlight Health, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019 and the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and our report dated February 24, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Note 2. Summary ofAccounting Standards and Significant Accounting Policies


Basis of Presentation and Principles of Consolidation
The consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles ("GAAP"(“GAAP”). In the opinion of management, the information herein reflects all adjustments, consisting only of normal recurring adjustments except as otherwise noted, considered necessary for a fair statement of results of operations, financial position, stockholders' equity and cash flows. The consolidated financial statements include the results of Castlight and its wholly ownedwholly-owned U.S. subsidiary.
During the fourth quarter of 2017, we adopted the requirements of Accounting Standards Update ("ASU") No. 2016-18, “Statement of Cash Flows” as discussed later in this note. All amounts and disclosures set forth in this Form 10-K have updated to comply with the new standard, as indicated by the “as adjusted” footnote.subsidiaries.
Use of Estimates
The preparation of consolidated financial statements in conformity with GAAP requires the Company to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. These estimates include, but are not limited to the determination of:

Variable consideration included in the transaction price of the relativeCompany’s contracts with customers;
The standalone selling prices forprice of the Company's services, certain assumptionsperformance obligations in the Company’s contracts with customers;
Assumptions used in the valuation of itscertain equity awardsawards;
Assumptions used in the calculation of goodwill impairment, including the forecast of future cash flows and discount rate; and
Assumptions used in the calculation of right-of-use (“ROU”) assets and lease liabilities for operating leases, including lease terms and the fair value of assets acquired and liabilities assumed for business combinations. Company’s incremental borrowing rate.

Actual results could differ from those estimates, and such differences could be material to the Company'sCompany’s consolidated financial position and results of operations.


Segment Information
The Company's chief operating decision maker, its CEO, reviews the financial information presented on a consolidated basis for purposes of allocating resources and evaluating the Company's financial performance. Accordingly, the Company has determined that it operates in a single reportable segment, cloud-based products.


Revenue Recognition
The Company derives its revenueRevenues are derived primarily from sales of cloud-basedcontracts with customers for subscription serviceservices and professional services. Revenues are recognized when control of these services contracts. The Company's cloud-based subscription service contracts are generally three yearsis transferred to the Company’s customers, in length.
The Company's cloud-based subscription service contractsan amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Revenues do not provide customers with the right to take possession of the software supporting the cloud-based service and, as a result, are accounted for as service contracts.
The Company commences revenue recognition for its cloud-based subscription service and professional services when all of the following criteria are met:
there is persuasive evidence of an arrangement;
the service has been provided to the customer;
collection of the fees is reasonably assured; and

include sales taxes.

We determine revenue recognition through the amountfollowing steps:

Identification of feesthe contract, or contracts, with a customer;
Identification of the performance obligations in the contract;
Determination of the transaction price;
Allocation of the transaction price to be paid by the customer is fixedperformance obligations in the contract; and
Recognition of revenue when, or determinable.as, the Company satisfies a performance obligation.
The Company's subscription and professional service arrangements do not contain refund provisions for fees earned related to services performed. The Company does, however, have commitments under service-level agreements, as discussed under "Warranties and Indemnification" below.
Subscription Revenue. Subscription revenue recognition commences on the date that the Company's cloud-based service isCompany’s subscription services are made available to the customer, which is consideredthe Company considers to be the launch date, provided all ofand subscription revenue is generally recognized over the other criteria described abovecontract term.

Fees forAdditionally, some of the Company’s subscription contracts include audit provisions. The Company considers fees related to performance incentives are considered contingent revenue, and are recognized over the remaining term of the related subscription arrangement commencingaudit provisions to be variable consideration. The Company estimates variable consideration at the time theymost likely amount to which it expects to be entitled. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are earned.based largely on an assessment of its anticipated performance as well as other information available to the Company. The Company reassesses its estimates related to variable consideration each reporting period and records adjustments when appropriate.
Professional Services and Other Revenue. Professional services and other revenue is primarily comprised of implementation services and communication services related to the Company's cloud-based subscription service. Nearly all of the Company's professional services are sold on a fixed-fee basis. The Company does not have standalone value for its implementation services. Accordingly, the Company recognizes implementation
Professional services and other revenue in the same manner as the associated cloud-based subscription service, beginning on the launch date, provided all other criteria described above have been met. Communication services have standalone value and the associatedalso includes revenue is recognized over the contractual term, generally one year, commencing when the revenue recognition criteria have been met. Revenue from products sold through ourthe Company’s online market placemarketplace and add-on subscription productsservices made available from other ecosystem partnerspartners. These revenues are recognized on a net basis principallyprimarily because we are not the primary obligor to the end-customers.
Multiple Deliverable Arrangements. To date, the Company has generated substantially all its revenue fromacts as an agent in these contracts.

Contracts with Multiple Performance Obligations. Most of the Company’s contracts have multiple deliverable arrangementspromised services consisting of multi-year cloud-based subscription services and professional services, including implementation services and communication services. For arrangementscontracts with multiple deliverables,promised services, the Company evaluates whether the individual deliverables qualify as separate units of accounting. In order to treat deliverables in a multiple deliverable arrangement as separate units of accounting, the deliverables must have standalone value upon delivery.promised services are distinct. If the deliverables have standalone value upon delivery, the Company accounts for each deliverable separately andpromised services are distinct, revenue is recognized for the respective deliverables as they are delivered.performance obligation separately. If one or more of the deliverables dopromised services are not have standalone value upon delivery,distinct, the deliverablespromised services that doare not have standalone valuedistinct are generally combined with the Company's cloud-based subscription service, and revenue for the respective combined unitperformance obligation is recognized over the remaining term of the cloud-based subscription service.

The Company's deliverables have standalone value if we or any other vendor sells a similar service separately. The Company has concluded that it has standalone value for its cloud-based subscription service as it sells these services separately through renewals and for its communication services as other vendors sell similar services separately. Conversely, the Company has concluded that its implementation services doare not have standalone value,distinct, primarily because these services are not capable of being distinct as the Company and others do not yet sell thesecustomer cannot benefit from the implementation services separately.on their own. Accordingly, the Company considers the separate units of accountingperformance obligations in itscontracts with multiple deliverable arrangementspromised services to be the communication services and a combined deliverableperformance obligation comprised of cloud-based subscription services and implementation services.
When
The transaction price for contracts with multiple deliverables included in an arrangement are separable into different units of accounting, the arrangement considerationperformance obligations is allocated to the identified separate units of accountingperformance obligations based on their relativestandalone selling price. Multiple deliverable arrangements accounting guidance provides a hierarchy to use when determining the relativeThe Company determines standalone selling price for each unit of accounting. Vendor-specific objective evidence, or VSOE, of selling price, based on the price at which the item is regularly sold by the vendor on a standalone basis, should be used if it exists. If VSOE of selling price is not available, third-party evidence, or TPE, of selling price is used to establish the selling price if it exists. If TPE does not exist, the Company estimates the best estimated selling price, or BESP. VSOE does not currently exist for any of its deliverables. Additionally, the Company does not believe TPE is a practical alternative due to differences in its cloud-based subscription service compared to other parties and the availability of relevant third-party pricing information for its cloud-based subscription service and its other services. Accordingly, for arrangements with multiple deliverables that can be separated into different units of accounting, the Company allocates the arrangement fee to the separate units of accountingprices based on its BESP. overall pricing objectives taking into consideration market conditions and other factors, including the value of the contracts, the subscription services sold, and customer demographics.

Deferred revenue consists of professional services and cloud-based subscription services that have been billed in advance of revenue being recognized. The Company determines BESPinvoices its customers for its deliverables by considering its overall pricing objectives and market conditions. This includes evaluating the Company's pricing practices, its target prices, the size of its transactions, historical sales and its go-to-market strategy. The determination of BESP is made through consultation with and approval by management. For financial statement presentation purposes, the Company allocates the fees from its combined units of accounting tocloud-based subscription and professional services based upon their relative selling price.on the terms of the contract, which can be annual, quarterly or monthly installments. Deferred revenue that is anticipated to be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as non-current.


Costs of Revenue


Cost of revenue consists of the cost of subscription revenue and cost of professional services and other revenue.


Cost of subscription revenue primarily consists of data fees, employee-related expenses (including salaries, bonuses, benefits and stock-based compensation) related to, hosting costs of its cloud-based subscription service, cost of subcontractors, expenses for service delivery (which includes call center support), allocated overhead, the costs of data center capacity, amortization of internal-use software, and depreciation of certain owned computer equipment and software.software, and amortization of intangibles related to developed technology and backlog.


Cost of professional services and other revenue consists primarily of employee-related expenses (including salaries, bonuses, benefits and stock-based compensation) associated with these services, the cost of subcontractors, deferred and amortized professional services costs, travel costs.costs and allocated overhead. The time and costs of the Company's customer implementations vary based on the source and condition of the data the Company receivereceives from third parties, the configurations that the Company agrees to provide and the size of the customer.


Cost of subscription revenue is expensed as the Company incurs the costs. Cost of professional services and other revenue, to the extent it is incurred and is directly attributable to fulfillment of performance obligations under a customer contract, is deferred and amortized over the benefit period of five years.

Cash and Cash Equivalents


Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less from the date of purchase. The Company's cash and cash equivalents generally consist of investments in money market mutual funds U.S treasury securities and U.S. agency obligations. Cash and cash equivalents are stated at fair value.


Marketable Securities


The Company's marketable securities consist of U.S. agency obligations and U.S. treasury securities, with maturities at the time of purchase of greater than three months. Marketable securities with remaining maturities in excess of one year are classified as noncurrent.non-current. The Company classifies its marketable securities as available-for-sale at the time of purchase based on its intent and are recorded at their estimated fair value. Unrealized gains and losses for available-for-sale securities are recorded in other comprehensive income/loss. The Company evaluates its investments to assess whether those with unrealized Unrealized losses for available-for-sale securities are recorded in other comprehensive income/loss, positions are other than temporarily impaired. The Company consider impairments to be other than temporary if they are relatedunless the losses relate to deterioration in credit risk or if it is likely it will sell the securities before the recovery of their cost basis. In these cases, the unrealized losses are reported in other income, net in the consolidated statements of operations. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income, net in the consolidated statements of operations.


Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded when invoiced and at the invoiced amount, net of allowances for doubtful accounts. When accounts receivable are recorded, the related revenue may not commence until a later date depending on the nature of the services invoiced. The allowance for doubtful accounts is based on the Company's assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for doubtful accounts by considering historical information such as the age of each outstanding invoice and the collection history of each customer to determine whether a specific allowance is appropriate. In addition, the Company considers current economic conditions, and expected future economic conditions, to determine future expected losses. Accounts receivable deemed uncollectable are charged against the allowance for doubtful accounts when identified. For all periods presented, the allowance for doubtful accounts was not significant.

Amortization of deferred commissions is included in sales and marketing expense in the accompanying consolidated statements of operations. All costs deferred are reviewed for impairment quarterly.


Deferred Professional Service Costs

Deferred professional service costs are the direct costs incurred to fulfill subscription contracts that occur prior to the launch of the Company’s subscription services. Professional service costs, which primarily consist of employee related expenses attributable to launch activities, are deferred and then amortized on a straight-line basis over a period of benefit that the Company has determined typically to be five years for the same reasons as described in the deferred commissions disclosure above. Deferred professional service costs are recoverable through future revenues. Amortization of deferred professional service costs is included in cost of professional services and other revenue in the accompanying consolidated statements of operations. All costs deferred are reviewed for impairment quarterly.

Property and Equipment
Property and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the respective asset as follows:follows (in years):
Software3–5 years
Computer equipment3 years
Furniture and equipment5–7 years
Leasehold improvementsShorter of the lease term or the estimated useful lives of the improvements
Software3-5
Computer equipment3
Furniture and equipment5-7
Leasehold improvementsShorter of the lease term or the estimated useful lives of the improvements
Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is reflected in the consolidated statement of operations for the period realized.


Internal-Use Software


For the Company's development costs related to its cloud-based subscription service, the Company capitalizes costs incurred during the application development stage. Costs related to preliminary project and post-implementation stages are expensed as incurred. Capitalized software development costs are included as part of property and equipment and are amortized on a straight-line basis over the technology's estimated useful life, which is generally three years. The amortization expense is recorded as a component of cost of subscription revenue and was $1.0$0.3 million, $0.0 million, and $0.9$0.8 million for the years ended December 31, 20172020, 2019, and 2016,2018, respectively.

The Company did not have any capitalized software development costs of $0.6 million and $0.3 million and for the years ended December 31, 20172020 and December 31, 2016.2019, respectively.
Restricted Cash

Restricted cash is included in Prepaid expenses and other current assets or Restricted cash, non-current depending on the remaining term of the restriction and consists of a letterletters of credit related to the Company'sCompany’s leased office space.
Business Acquisitions
The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired users and acquired technology, useful lives, and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.

Goodwill
The Company reviews goodwill for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company adopted ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, during the fourth quarter of fiscal 2017, which eliminated step 2 from the testing of goodwill impairment. The Company has elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of the Company’s single reporting unit is less than its carrying amount. Based on the qualitative assessment, ifIf it is determined that it is more likely than not that its fair value is less than its carrying amount, the Company performs a quantitative impairment test of goodwill, in which the fair value of the Company's single reporting unit is compared to its carrying value. Any excess of the goodwill carrying amount over the fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value. As of December 31, 2017, no impairment of goodwill has been identified.Refer to Note 5 – Goodwill and Intangible Assets to the consolidated financial statements for further information on goodwill.
Intangible Assets
Acquired finite-lived intangible assets are amortized over their estimated useful lives. The Company evaluates the recoverability of its intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of intangible assets is not recoverable, the carrying amount of such assets is reduced to fair value. The Company has not recorded any such impairment charges.
Deferred Revenue
Deferred revenue consists of professional services and cloud-based subscription services that have been billed in advance of revenue being recognized. Additionally, deferred revenue consists of professional services that have been billed and delivered but the revenue is being deferred and recognized together with a cloud-based subscription contract as a combined unit of accounting. Leases

The Company invoicesdetermines if an arrangement is a lease and its customers for its cloud-based subscription servicesclassification at lease inception. Operating lease liabilities are recognized at the commencement date of the lease based on the termspresent value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the lease commencement date to compute the present value of lease payments when the implicit rate is not readily determinable. ROU assets are measured at lease inception based on the initial measurement of the contract, which can be annual, quarterly or monthly installments.lease liability, plus any prepaid lease amounts, less any lease incentives. The Company invoices its customersdoes not recognize ROU assets or lease liabilities for its professional servicesleases with a term of 12 months or less. Lease terms do not include options to extend or terminate the lease unless it is reasonably certain that the option will be exercised. Generally, lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company's lease agreements have both lease and the first year of communication services generally at contract execution. Deferred revenue that is anticipatednon-lease components. The Company has elected to be recognized during the succeeding 12-month period is recorded as current deferred revenue,account for lease and the remaining portion is recorded as noncurrent.non-lease components on a combined basis.


Stock-based Compensation
All stock-based compensation to employees is measured based on the grant-date fair value of the awards and recognized in the Company's consolidated statements of operations over the period during which the employee is required to perform services in exchange for the award (generally the vesting period of the award). The options assumed and awarded in connection with the acquisition of Jiff were valued using the Monte Carlo simulation model.Company accounts for forfeitures as they occur. The Company estimates the fair value of all other stock options grantedand stock purchase rights under the employee stock purchase plan using the Black-Scholes option valuation model. For restricted stock units, fair value is based on the closing price of the Company's Class B common stock on the grant date. Compensation expense is recognized over the vesting period of the applicable award using the straight-line method. For awards with performance based and service vesting conditions, compensation costexpense is recognized over the requisite service period if it is probable that the performanceperformance-based condition will be satisfied based on the accelerated attribution method. For awards with market based and service vesting conditions, compensation expense is recognized over the requisite service period using the accelerated attribution method.


Income Taxes
The Company accounts for income taxes using the liability method, under which deferred tax assets and liabilities are determined based on the future tax consequences attributable to differences between the financial reporting carrying amounts of existing assets and liabilities and their respective tax bases and tax credit and net operating loss carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates that are expected to be in effect when the differences are expected to reverse.
The Company assesses the likelihood that deferred tax assets will be recovered from future taxable income, and a valuation allowance is established when necessary to reduce deferred tax assets to the amounts more likely than not expected to be realized.

The Company recognizes and measures uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken by determining if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained in an audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. Significant judgment is required to evaluate uncertain tax positions. The Company evaluates its uncertain tax positions on a regular basis. The Company's evaluations are based on a number of factors, including changes in facts and circumstances, changes in tax law, correspondence with tax authorities during the course of audit and effective settlement of audit issues.


Warranties and Indemnification
The Company's cloud-based subscription service is generally warranted to be performed in a professional manner and in a manner that will comply with the terms of the customer agreements.


The Company's arrangements generally include certain provisions for indemnifying customers against liabilities if there is a breach of a customer’s data or if the Company's service infringes a third party’s intellectual property rights. To date, the Company has not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in the financial statements. The Company has entered into service-level agreements with certain customers warranting, among other things, defined levels of performance and response times and permitting those customers to receive credits for prepaid amounts related to subscription services in the event that the Company fails to meet those levels. To date, the Company has not experienced any significant failures to meet defined levels of performance and response times as a result of those agreements.


The Company has also agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by the Company, arising out of that person’s services as its director or officer or that person’s services provided to any other company or enterprise at the Company's request. The Company maintains director and officer insurance coverage that would generally enable the Company to recover a portion of any future amounts paid. The Company may also be subject to indemnification obligations by law with respect to the actions of its employees under certain circumstances and in certain jurisdictions.


Advertising Expenses
Advertising is expensed as incurred. Advertising expense was $0.3$0.2 million, $0.6$0.1 million and $0.4$0.3 million for the years ended December 31, 2017, 20162020, 2019 and 2015,2018, respectively.

Recently Adopted Accounting Pronouncements
Effective January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses, and subsequent amendments (“ASC 326”). The standard changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The adoption of this standard did not have a material impact on the Company’s financial statements. The Company will continue to actively monitor the impact of the current coronavirus (“COVID-19”) pandemic on expected credit losses.
Statement
Effective January 1, 2020, the Company adopted ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (“ASU 2018-15”), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The adoption of Cash Flowsthis standard did not have a material impact on the Company’s financial position or results of operations.

Note 3. Revenue, Deferred Revenue, Contract Balances and Performance Obligations
Stock-based Compensation
In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment.” The guidance will change how companies account for certain aspects of share-based payments to employees. The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The Company adopted this guidance onsells to customers based in the United States. Starting January 1, 2017, using2020, the effective date of the Anthem enterprise license agreement, the Company began treating Anthem as a modified retrospective approach, and accordingly recordeddirect health plan customer rather than a cumulative-effect adjustment chargechannel partner. As a result, substantially all of approximately $0.4 million to the beginning accumulated deficit for the impact of electing to account for forfeitures as they occur. The adoption of this standard did not have any impact to the Statement of Operations or the Statement of Cash Flows. The Company is subject to full valuation allowance and thus has not utilized any excess tax benefits or realized any cash tax benefit related to stock compensation expense. The adoption of this standard did not have any material impact to the Company’s results of operationsCompany's revenues were generated through direct sales for the year ended December 31, 2017.2020. Indirect channel revenue represented approximately 28% of the Company’s total revenue for the year ended December 31, 2019.


GoodwillDeferred revenue as of December 31, 2020 and December 31, 2019 was $7.5 million and $10.7 million, respectively. Contract assets as of December 31, 2020 and December 31, 2019 were $9.4 million and $0.4 million, respectively. The increase in contract assets is primarily due to the Anthem enterprise license agreement that results in revenue recognized ahead of invoicing in the first year of that agreement.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” and has since updated the ASU. This ASU replaces existing revenue recognition standards with a comprehensive revenue measurement and recognition standard and expanded disclosure requirements. The new standard will be effective for the Company beginning January 1, 2018.

The new standard permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). The Company plans to adopt under the full retrospective method.

Based on its assessment to date, the Company determined a significant area impacted by the adoption of the new standard will be related to the Company’s costs to fulfillremaining performance obligations from non-cancelable contracts with customers.customers as of December 31, 2020 was $163.0 million. The Company currently expenses costsexpects to fulfill contracts when they are incurred. The new standard states that an entity shall recognize as assets certain costs incurred to fulfill contracts. The new standard also states that costs to fulfill contracts that are recognized as assets are amortized on a systematic basisapproximately 70% of this balance over a period that is consistentthe next 12 months, with the transfer to the customer of the goods or services to which those assets relate. The Company believes certain of its costs to fulfill contracts will beremaining balance recognized thereafter. Remaining performance obligations are defined as assets under the new standarddeferred revenue and we have determined the amortization period of those costsamounts yet to be five years.

Additionally, based on its assessment to date, the Company determined another area impacted by the adoption of the new standard will be related to the Company’s costs to obtain contracts with customers. The Company currently capitalizes certain sales commissions and amortizes those costs overbilled for the non-cancelable portion of its subscription contracts.

Anthem Agreement

In October 2019, Castlight entered into a 30-month enterprise license agreement with Anthem, Inc., effective January 1, 2020, that extends and expands the Company's existing relationship with Anthem first announced in 2015. The agreement includes Castlight’s core care guidance technology, the Engage health navigation platform, and a new, standard states that certain costs to obtain a contract shall capitalizednon-exclusive license for some of Castlight’s underlying health navigation platform technology services, such as transparency and then amortized on a systematic basis that is consistent withpersonalization.

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases.” The guidance will require lessees to put all leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The guidance will be effective for the Company beginning January 1, 2019 and early adoption is permitted. The Company is evaluating the accounting, transition and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption. At this point in time, the Company does not intend to adopt the standard early.



Note 3. Business Combinations
On April 3, 2017, the Company completed its acquisition of Jiff. Jiff provides an enterprise health benefits platform that serves as a central hub for employee wellbeing and employee benefit programs. The acquisition enables the Company to provide the full spectrum of wellbeing, healthcare decision support and a benefits hub all in one complete package. The Company acquired Jiff for approximately 27,000,000 shares and options.

At the closing on April 3, 2017, Venrock, a holder of more than 5% of the Company’s capital stock, acquired a total of 3,965,979 shares of the Company’s Class B common stock in exchange for its shares of Jiff capital stock. Venrock will also receive its pro rata share of any additional contingent consideration further described below. Bryan Roberts, the Chairman of the Company’s Board of Directors, is a Partner at Venrock. Accordingly, this was a related party transaction.

CASTLIGHT HEALTH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



The Company’s Board appointed a Special Committee (comprised solely of disinterested directors) to which it delegated the full and exclusive power, authority and discretion of the Castlight Board to evaluate, assess, and approve the Jiff transaction on its behalf, including retaining a financial advisor for an opinion on the fairness of the financial conditions of the transaction. The transaction was approved solely by the Special Committee which concluded that the transaction terms were fair to Castlight, and the transaction was in the best interests of Castlight and its stockholders.

As part of the merger, certain stockholders and option holders were to receive an aggregate of 1,000,000 shares of the Company’s Class B common stock or options if the Jiff business achieved at least $25 million in revenue in 2017 and an aggregate of 3,000,000 shares of Class B common stock or options if the Jiff business achieved at least $25 million in net new bookings during 2017 (“the milestones”). As of December 31, 2017, the Company evaluated and determined that both the milestones were not met. Additionally, all options for Jiff common stock held by Jiff employees who became employees of the combined company were converted into options to purchase the Company’s Class B common stock.

The following table summarizes the components of the purchase consideration transferred based on the closing price of the Company’s stock as of the acquisition date (in thousands):
  Fair value
Fair value of Company Class B common stock (25,054,049 shares @ $3.65 per share) $91,447
Fair value of contingent consideration 671
Fair value of assumed Jiff options attributable to pre-combination services 9,574
Transaction costs paid on behalf of Jiff 4,498
Estimated purchase price consideration $106,190
For the Jiff options assumed as part of the acquisition, the Company applied the ratio of pre-combination service provided, on a grant-by-grant basis, to the total service period and applied this ratio to the acquisition date fair value of the Jiff awards.

The Company determined that the contingent consideration shares associated with the milestones are one unit of account, and the Company classified the contingent consideration as a liability as the arrangement can be settled in a variable number of shares and is not considered fixed-for-fixed. Based on the probability of completing the milestones and changes in the fair value of the Company’s common stock, the Company used a Monte Carlo simulation model to determine the fair value of the contingent consideration liability which was $0.7 million at the date of acquisition. As of December 31, 2017, the Company reversed the contingent consideration liability as the milestones were not met. As a result, $0.7 million of income was recorded in general and administrative expenses for the year ended December 31, 2017. See Note 6 –Fair Value Measurements for the fair value measurement disclosure on the contingent consideration liability.

The Company has accounted for this acquisition as a business combination. The method requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date.     

The allocation of purchase consideration to assets and liabilities is not yet finalized. The Company continues to evaluate the fair value of certain assets and liabilities related to the acquisition of Jiff. Additional information, which existed as of the acquisition date but was at that time unknown to us, may become known to us during the remainder of the measurement period. Changes to amounts recorded as assets or liabilities may result in a corresponding adjustment to goodwill. The preliminary estimated fair values of assets acquired and liabilities assumed may be subject to change as additional information is received. The fair values of the assets acquired and liabilities assumed by major class in the acquisition of Jiff as of December 31, 2017 were recognized as follows (in thousands):

The fair values assigned to tangible assets acquired, liabilities assumed and identifiable intangible assets are based on management’s estimates and assumptions. The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. The goodwill balance is primarily attributed to the cross-selling opportunities, cost synergies, and a knowledgeable and experienced workforce which play an important role in the integration of the acquired customers and technology. The goodwill balance is not deductible for U.S. income tax purposes.

The following table sets forth the fair value components of identifiable acquired intangible assets (in thousands) and their estimated useful lives (in years):

To determine the net cash flow that a market participant would expect to realize from licensing the Company's technology, the Company estimated a net royalty rate, which excludes any expenses that would be incurred to maintain the current functionality of the technology.

The Company has included the financial results of Jiff in the consolidated statements of operations from the date of acquisition. For the year ended December 31, 2017, $10.9 million revenue attributable to Jiff was included in the consolidated results of operations, and the associated operating income was immaterial. The Company incurred $3.1 million of acquisition-related costs for the year ended December 31, 2017 that were recognized in general and administrative expenses.

The unaudited pro forma financial information in the table below summarizes the combined results of operations for the Company and Jiff as if the companies were combined as of the beginning of 2016. The historical consolidated financial statements have been adjusted in the pro forma combined financial statements to give effect to pro forma events that are directly attributable to the business combination and factually supportable. The unaudited pro forma financial information presented includes the business combination accounting effects resulting from the acquisition, including amortization charges from acquired intangible assets, stock-based compensation, and acquisition-related costs. The unaudited pro forma financial information as presented below is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisitions had taken place at the beginning of 2016.

Note 4.5. Goodwill and Intangible Assets


Impairment

The Company determined that the significant decline in the U.S. economy as a result of the COVID-19 pandemic, together with the decline in the Company’s stock price, constituted a triggering event, which required the Company to perform interim impairment analyses related to its long-lived assets and goodwill during the first quarter of 2020. The impairment analysis for long-lived assets indicated that the assets were recoverable; therefore, no impairment was recorded. After assessing long-lived assets, the Company performed a goodwill impairment analysis and determined that the carrying value of its only reporting unit exceeded its fair value by approximately $50.3 million. The fair value was determined using the income approach. The Company believes that the income approach is the most reliable indication of fair value since it incorporates future estimated revenues and expenses for the reporting unit that the market approach may not directly incorporate. In addition to future estimated revenue and expenses, the determination of fair value included assumptions related to a discount rate.

As of December 31, 2020, the Company determined that there were no indicators present to suggest that it was more likely than not that the fair value of the reporting unit was less than its carrying amount. The Company will continue to monitor its goodwill on a quarterly basis for indicators of impairment, including but not limited to, further declines in the stock price. Accordingly, there may be future impairments.

Goodwill


Currently, all of theThe Company’s goodwill relates entirely to the acquisition of Jiff.Jiff in 2017. The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill.

Intangible assets, net

Identified intangible assets are recorded at their estimated fair values at the date of acquisition and are amortized over their respective estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are used. Subsequent to the end of the second quarter of 2019, the Company realized elevated churn related to legacy Jiff customers. As a result, the Company performed an analysis of realized churn and future forecasts and updated its estimate of the original useful life of customer relationships and backlog in the third quarter of 2019. The estimated useful life of customer relationships was revised from 10 years to 6 years, and the estimated useful life of backlog was revised from 3 years to 2.5 years. These updates in useful lives were accounted for as a change in accounting estimate and were applied prospectively to the remaining carrying amounts.

Note 6.7. Fair Value Measurements
The Company measures its financial assets and liabilities at fair value at each reporting period using a fair value hierarchy that requires that the Company maximizes the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:
Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2—Include other inputs that are directly or indirectly observable in the marketplace.
Level 3—Unobservable inputs that are supported by little or no market activity.

73

Table of Contents
CASTLIGHT HEALTH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


The fair value of marketable securities included in the Level 2 category is based on observable inputs, such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. These values were obtained from a third-party pricing service and were evaluated using

The Company classified its contingent consideration liability in connection with the acquisition of Jiff within the Level 3 category, as factors used to develop the estimated fair value are unobservable inputs that are not supported by market activity. At the time of acquisition, the Company estimated the fair value of the contingent consideration liability based on the Monte Carlo simulation model. The fair value of the contingent consideration was calculated with numerous projected outcomes, the results of which are averaged and then discounted to estimate the present value. Some of the more significant assumptions inherent in the development of the Monte Carlo simulation model included bookings and revenue forecasts, asset-level volatility, stock price volatility, correlation between stock price and revenue, risk-free rate, weighted average cost of capital (“WACC”), and stock price. Any change in these assumptions could result in a significantly higher (lower) fair value measurement. The fair value of the contingent consideration was remeasured each reporting period. During the fourth quarter of 2017, the Company reversed the contingent consideration liability since the milestones were not met.

Lyra was considered a related party to the Company because two of the Company’s directors, Dr. Roberts and Mr. Ebersman, served on the Lyra board of directors and Mr. Ebersman is the Lyra chief executive officer. Prior to the sale of the investment in Lyra, the Company evaluated all its transactions with Lyra and determined that Lyra was a variable interest entity (“VIE”) for the Company but that it was not required to consolidate the operations of the VIE.

Because Lyra was a related party and potential buyers were also related parties, the Company formed an independent committee of the Company's board of directors (the "Independent Committee"), comprised solely of disinterested directors, to approve the sale. The Company engaged an independent third- party valuation expert to assist in determining the fair value of the Company's investment in Lyra. Based in part on the valuation performed, the Company negotiated a selling price of $5.5 million, which the Independent Committee approved after concluding that the transaction terms were fair to the Company. The sale resulted in a pre-tax gain of $1.4 million which is recorded in other income, net within the consolidated statements of operations.

The lawsuits were brought by purported stockholders of the Company seeking to represent a class consisting of all those who purchased the Company’s stock pursuant or traceable to the Registration Statement and Prospectus issued in connection with its IPO, alleging claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933. On March 28, 2016, the parties to the consolidated actions reached a mutually acceptable resolution by way of a mediated cash settlement for an aggregate amount of $9.5 million, and the Court entered final approval of the settlement on October 28, 2016. As a result of the settlement, Castlight recorded a net charge of $2.9 million to general and administrative expense in 2016. This amount represents the portion of settlement that was not covered by insurance and legal fees incurred in 2016 regarding this matter. Legal Matters

The total grant-date fair value of stock options vested, including options assumed related to Jiff acquisition in 2017, during the years ended December 31, 2017, 2016 and 2015 was $6.7 million, $4.9 million and $10.8 million, respectively.
The total intrinsic value of the options exercised, including options assumed related to Jiff acquisition in 2017, during the years ended December 31, 2017, 2016 and 2015, was $2.6 million, $4.7 million and $25.3 million, respectively. The intrinsic value is the difference of the current fair value of the stock and the exercise price of the stock option.
As of December 31, 2017, the Company had $3.8 million in unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a weighted-average period of approximately 2.3 years.
Assumed and Awarded Jiff Options
In connection with the acquisition of Jiff, the Company assumed 5.4 million options with a grant date fair value of $14.1 million. These options are categorized as performance stock options, as the final exercise price at the time of acquisition was to be determined upon the achievement of certain milestones. The total acquisition date fair value of $14.1 million allocation to the pre-combination services and post-combination services was $9.6 million and $4.5 million, respectively. Any subsequent changes in the fair value of the assumed Jiff options resulting from achievement of the earn-out milestones were to be accounted as post-combination stock compensation expense. For the year ended December 31, 2017, the Company did not make changes to the assumed Jiff options as earn-out milestones were not met.

During 2017, the Company awarded 1.4 million PSUs to certain employees. The number of shares that would eventually vest depends on achievement of performance targets for 2017, as determined by the compensation committee of the Company's board of directors, and may range from 0% to 150% of the targeted award amount. Once the performance is determined and a targeted award amount is fixed, the target number of PSUs, if any, will vest in eight quarterly installments, subject to recipients' continued service, beginning on February 15, 2018. The compensation expense associated with the PSUs is recognized using the accelerated method. No expense was recorded in 2017 as the Company determined that the performance conditions were not met.

Stock-Based Compensation to Employees
All stock-based compensation to employees is measured based on the grant-date fair value of the awards and is generally recognized in the Company's statement of operations over the period during which the employee is required to perform services in exchange for the award (generally the vesting period of the award). Except for the stock options assumed and granted related to Jiff acquisition, the Company estimates the fair value of stock options granted using the Black-Scholes option-valuation model. For restricted stock units, fair value is based on the closing price of the Company's Class B common stock on the grant date. Compensation cost is generally recognized over the vesting period of the applicable award using the straight-line method. For awards with performance based and service vesting conditions, compensation cost is recognized over the requisite service period if it is probable that the performance condition will be satisfied based on the accelerated attribution method.
The assumptions used in the Black-Scholes option-pricing model were determined as follows:
Volatility. SinceBeginning in 2020, volatility is based on the Company's historical volatility over the expected life of its stock awards. Prior to 2020, the Company doesdid not have enough trading history for its Class B common stock, therefore, the expected volatility was derived from the historical stock volatilities of peer group companies within the Company's industry. In evaluating peer companies, the Company considered factors such as nature of business, customer base, service offerings and markets served.
Risk-Free Interest Rate. The risk-free rate that the Company used is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options.
Expected Life. The expected term represents the period that the Company's stock-based awards are expected to be outstanding. The expected term assumptions were determined based on the vesting terms, exercise terms and contractual lives of the options.
Risk-Free Interest Rate. The risk-free rate that the Company used is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options.

Dividend Yield. The Company has never declared or paid any cash dividends and dodoes not plan to pay cash dividends in the foreseeable future, and therefore,future. Therefore, the Company uses an expected dividend yield of zero.0.

Fair Value of Common Stock. Prior to the Company's initial public offering in March 2014, the Company's board of directors considered numerous objective and subjective factors to determine the fair value of the Company's Class A common stock at each grant date. These factors included, but were not limited to, (i) contemporaneous valuations of Class A common stock performed by unrelated third-party specialists; (ii) the prices for the Company's Preferred Stock sold to outside investors; (iii) the rights, preferences and privileges of the Company's Preferred Stock relative to its Class A common stock; (iv) the lack of marketability of the Company's Class A common stock; (v) developments in the business; and (vi) the likelihood of achieving a liquidity event, such as an initial public offering or a merger or acquisition of the Company, given prevailing market conditions.
Since the Company's initial public offering, theThe Company has used the market closing price for its Class B common stock as reported on the New York Stock Exchange to determine the fair value of the Company's common stock.
In addition to assumptions used in the Black-Scholes option-pricing model, prior to the adoption of ASU 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment” in 2017, the Company estimated a forfeiture rate to calculate the stock-based compensation for its awards based on an analysis of its actual forfeitures.The Company used historical data to estimate pre-vesting option forfeitures and recorded stock-based compensation expense only for those awards that are expected to vest. With the adoption of ASU 2016-09, the Company no longer estimates forfeitures but accounts for forfeitures as they occur.
Except for the stock options assumed and granted related to Jiff acquisition, theThe fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions:

Transactions with SAP Technologies, Inc.
In May 2016, the Company entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with SAP Technologies, Inc. (“SAP”) pursuant to which it sold and issued to SAP 4.7$18.3 million shares of its Class B Common Stock and a warrant (the “Warrant”), which gave SAP right to purchase up to 1.9 million shares of the Company's Class B Common Stock for an exercise price of $4.91, subject to certain conditions. The net proceeds from this transaction were $17.8 million, net of issuance costs, and are being used for working capital and other general corporate purposes.

The Warrant was set to expire four years from the date the Company enters into agreements with SAPin unrecognized compensation cost related to the distribution and the resellingnon-vested RSUs, which is expected to be recognized over a weighted-average period of the Company’s solutions (the “Alliance Agreement”) within a prescribed period.

However, the Alliance Agreements were not executed prior to that date and as a result, the Warrant expired.approximately 2.6 years.

The shares and Warrant were considered freestanding instruments from each other and were classified within stockholders’ equity. Initially, upon execution of the Securities Purchase Agreement, the Company preliminarily allocated the net proceeds to the shares and Warrant and also to a customer prepayment liability classified within accrued expenses and other current liabilities that represented the future obligations under the Alliance Agreement. The Company updated its preliminary allocation of the net proceeds as a result of the modification of the Warrant in the second quarter of 2017, which resulted in a change in classification of customer prepayment liability into other assets. Subsequent to expiration, during the fourth quarter of 2017, the Company released the associated other asset in the consolidated balance sheet and recorded a $1.1 million non-cash charge in other income, net in the consolidated statement of operations. The expiration did not result in a change to the amounts recorded within stockholders' equity.

The Company has provided a full valuation allowance for its net deferred tax assets as of December 31, 20172020 and 2016,2019, due to the uncertainty surrounding the future realization of such assets. Therefore, no0 benefit has been recognized for the net operating loss carryforwards and other deferred tax assets.


The valuation allowance decreased by $4.9 million and increased by $14.6$1.3 million during the years ended December 31, 2017 and 2016, respectively. The decrease in the valuation allowance for the year ended December 31, 2017 was related to a decrease in the U.S. corporate federal income tax rate from 34% to 21%, as well as the acquired deferred tax liabilities from Jiff.
On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act of 2017 (the “Act”) into law. The new legislation decreases the U.S. corporate federal income tax rate from 35% to 21% effective January 1, 2018. The Act also includes a number of other provisions including the elimination of loss carrybacks and limitations on the use of future losses and repeal of the Alternative Minimum Tax regime. The Company has calculated its best estimate of the impact of the Tax Act in its year end income tax provision in accordance with its understanding of the Tax Act and guidance available as of the date of this filing. The provisional amount related2020, due to the re-measurement of certain deferred tax assets and liabilities based on the rates at which they are expected to reverseincrease in the future was a net decrease related to deferred tax assets and deferred tax liabilities of $54.6 million, with a corresponding offsetting change in valuation allowance of $54.6 millionoperating losses for the year ended December 31, 2017.
On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, the Company has determined that the adjustment to deferred taxes was a provisional amount and a reasonable estimate at December 31, 2017. The determination of the benefit from income taxes requires complex estimations, significant judgments and significant knowledge and experience concerning the applicable tax laws. Given that the Company is still in the transition period for the accounting for income tax effects of the Act, the current assessment on deferred tax assets is based on the currently available information and guidance. If in the future any element of the tax reform changes the related accounting guidance for income tax, it could affect the Company’s income tax position, and the Company may need to adjust the benefit from (provision for) income taxes accordingly.ongoing operations.
As of December 31, 2017,2020, the Company had approximately $421.6$494.2 million of federal and $276.7$330.0 million of state net operating loss carryforwards available to offset future taxable income. If not utilized, the federal and state net operating loss carryforwards begin to expire in 2028 and 2028, respectively.

Note 15. Net Loss per Share
Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase.period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including Preferred Stock and outstanding stock options and warrants, to the extent dilutive. Basic and diluted net loss per share was the same for each period presented as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive.
When shares of both Class A and Class B common stock are outstanding, net loss is allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the year have been distributed. As the liquidation and dividend rights are identical, the net loss is allocated on a proportionate basis.

Note 17. Reduction in Workforce
On May 10, 2016,4, 2020, the Company’s Board of Directors committedCompany announced its intent to undertake a program to reduce its workforce as part of the Company’s efforts to respond to the COVID-19 pandemic and ensure longer-term financial stability for the Company in light of the ongoing economic challenges resulting from COVID-19 and its impact on the Company’s business (the “Program”). The Program involved the termination of approximately 60 employees, representing 13% of the Company’s headcount. For the year ended December 31, 2020, the Company incurred charges of approximately $2.0 million related to employee severance and benefits costs under the Program, all of which are cash expenditures. As of September 30, 2020, all costs were fully paid out.

In addition, as part of its cost reductions in light of the COVID-19 pandemic, the Company implemented reductions in base salary for its employees, effective May 16, 2020, consisting of a 30% reduction for the Company’s Chief Executive Officer, 25% reduction for the Company’s Chief Financial Officer, 20% reduction for members of the Company’s executive leadership team, and tiered reductions of 10% - 15% for other employees with salaries above $100,000, which the Company anticipated would last at least six months, and would be re-evaluated at that time. Members of the Company’s board of directors also voluntarily agreed to forego 50% of their cash compensation for the duration of the employee salary reductions. In early November 2020, management, in consultation with the board of directors, determined that it would reinstate full salaries for those who were impacted by the salary reduction and restore the board of director’s cash compensation to its original levels, effective November 16, 2020.
On July 30, 2018, the Company announced its intent to undertake a program to reduce its workforce in order to reducedecrease expenses, align its operations with evolving business needs and improve efficiencies.

For the year ended December 31, 2016,2018, the Company incurred charges of $0.8approximately $2.1 million for this reduction, all of which were related to severance costs. As of December 31, 2016,2018, all costs have beenwere fully paid out.

None.



Item 9A. Controls and Procedures


Evaluation of Disclosure Controls and Procedures


Our management, with the supervision and participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the(the" Exchange Act)Act"), as of the end of the period covered by this report.


In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Our management recognizes that there are inherent limitations in the effectiveness of any internal control and that effective internal control over financial reporting may not prevent or detect misstatements. In addition, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.


Based on our management’s evaluation, our principal executive officer and principal financial officer concluded that, as of December 31, 2017,2020, our disclosure controls and procedures were designed at a reasonable assurance level and were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We are continually monitoring the COVID-19 pandemic to minimize any impact of the situation on the design and operating effectiveness of our internal controls.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f) and Rule 15d-15(f). Our management, including our Chief Executive Officerprincipal executive officer and Chief Financial Officerprincipal financial officer 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. Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment. Based on its evaluation under the framework in Internal Control - Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 20172020 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. We reviewed the results of management’s assessment with the Audit Committee of our Boardboard of Directors.
This Annual Report on Form 10-K does not includedirectors. The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by Ernst & Young LLP, an attestation report of the company’sindependent registered public accounting firm, regarding internal control over financial reporting. Management’sas stated in its report was not subject to attestation by the company’s registered public accounting firm pursuant to the ruleswhich is included in Part II, Item 8 of the SEC that permit emerging growth companies such as our company to provide only management’s report in the Annual Report on Form 10-K.
