ITEM 1. BUSINESS
Groupon is a global scaled two-sided marketplace that connects consumers to merchants. Consumers access our marketplace through our mobile applications and our websites, primarily localized groupon.com sites in many countries. We operate in two segments, North America and International, and historically we have operated in three categories, Local, Goods and Travel. In February 2020,See Item 1, Note 19, Segment Information, for additional information.
Currently, we announced that we plan to leverage our global leadership position in local commerce to focus on our Localgenerate service and Travel categories and to exit the Goods category by the end of 2020. Our vision is to make it easy for consumers around the world to discover and purchase local experiences from quality merchants who want to grow their businesses.

We earn serviceproduct revenue from transactions in which we earnthe following business operations.
Service Revenue from Local, Travel, and Goods Categories: Service revenue primarily represents the net commissions byearned from selling goods or services on behalf of third-party merchants. Those transactions generally involve a customer's purchase of a voucher through one of our online marketplaces that can be redeemed with a third-party merchant for goods or services (or for discounts on goods or services). Service revenue from those transactions is reported on a net basis and equalsas the purchase price receivedcollected from the customer forless the voucher less an agreed upon portion of the purchase price paidthat is payable to the third-party merchant. Service revenueWe also includesearn commissions that we earn when customers make purchases with retailers using digital coupons accessed through our digital propertieswebsites and mobile applications.
Product Revenue from voucherless merchant offerings.Goods Category: We earngenerate product revenue from direct sales of our first-party Goods merchandise inventory through our Goods category. Ourinventory. For product revenue from those transactions, we are the primary party responsible for providing the merchandise to the customer, we have inventory risk and we have discretion in establishing prices. As such, product revenue is reported on a gross basis as the purchase price received from the customer. AfterProduct revenue, including associated shipping revenue, is recognized when the merchandise is delivered to the customer. We fully transitioned to a third-party marketplace in North America in 2020 and in International in the fourth quarter of 2021. In a third-party marketplace model, our merchants generally assume inventory and refund risk; therefore, we exit theexpect our Goods category we will no longerto primarily generate product revenue oron a net basis within service revenue from goods offerings. We currently anticipate that when we cease operations in the Goods category, its financial results will be presented as a discontinued operation in our consolidated financial statements.

To do this, we shifted our strategy toward turning Groupon into the local experiences marketplace.

For merchants, we are continuing to exit our Goods category in 2020focus on being a better partner by offering self-service options, advertising products and focus our resources on the following four key priorities:

We use a variety of marketing channels to direct customers to the offerings available through these marketplaces, as described in the Marketing section below.

Total2,316
Other key operational functions include editorial,engineering, product, marketing and editorial.
Within our human capital strategy, there are five core pillars: Diversity, Equity & Inclusion, Workplace Culture & Values, Compensation & Benefits, Social Responsibility and Emerging Employee Needs.
Diversity, Equity and Inclusion. Diversity, equity and inclusion ("DEI") is integrated into our business and we are building a resilient, engaged and energized team of collaborative people from all over the world who celebrate diversity. We consider it vital to attract, develop and retain employees from underrepresented groups and build a global team that reflects the diversity of the merchants and customers we serve and the communities in which we live and work. We believe that a global team of employees with diverse experiences, backgrounds, skills and perspectives will allow us to take a more innovative approach to problem solving and lead to better outcomes and higher productivity. Our company-wide DEI program includes a range of initiatives and programs that have the overarching goal of making our employees, merchants and customers feel seen and valued. In 2021, we completed the following:
Implemented an analytics-based approach to provide data-driven insights and increase visibility as we aim to improve workforce diversity, identify inequities and reduce turnover;
Re-launched and expanded our Employee Resource Groups;
Enabled diverse merchant self-identification;
Expanded DEI programming;
Created and offered an inclusive leadership training program for employees; and
Recognized, celebrated and supported multiple merchant-facing campaigns and employee-facing celebrations including Asian American Pacific Islander Month, Pride Month, Juneteenth, National Black Business Month, National Hispanic Heritage Awareness Month, Global Diversity Awareness Month and Women’s Small Business Month.
As we look forward to 2022 and beyond, we plan to continue to build upon our existing initiatives to enable a thriving culture through a diverse workforce at a local level. Our global DEI vision and strategy are tied to the same operational goals as the rest of our organization, which help us design, lead and execute on a data-driven strategy, which we believe will ultimately lead to better business outcomes. We are making efforts to improve the representation and harness the diversity of our workforce - in particular, we are focused on increasing the number of women and people of color in leadership roles. Moving forward we plan to focus on the following:
Collecting and measuring the right data to enable us to improve workforce diversity, identify inequities and reduce turnover;
Increasing representation of underrepresented groups through the following:
Establishing more programs focused on the hiring and retention of members of underrepresented populations;
Sourcing and identifying a diverse range of applicants for all of the positions that we advertise, especially at Director and above levels, to specifically target our representation opportunities at more senior levels;
Building relationships with Historically Black Colleges and Universities and other organizations that serve underrepresented communities and populations to increase our pipeline of diverse candidates;
Providing programming and tools that help our employees incorporate DEI strategies and goals into their annual performance goals;
Offering workshops and other forums to allow our employees to become more culturally competent; and
Creating new programming to build and champion our diverse merchant base.
Workplace Culture and Values. To ensure we are supporting a thriving and vibrant culture, we conduct frequent Pulse Engagement Surveys throughout the year to help understand our employees’ needs and concerns

and uncover insights that will allow us to positively impact our employee experience. This survey covers a wide range of topics including leadership; culture; corporate strategy; DEI and manager support. In 2021, we had strong employee engagement scores.
Each of our employees play an important role in ensuring that we maintain a high level of business ethics, safety and integrity. To facilitate this, all employees complete our mandatory ethics training module annually. Additionally, we have established an internal process called Groupon Ethics Reporting Service, which is communicated to employees during the annual ethics training and can be used to bring to management’s attention a wide range of concerns, including violations of our policies.
To support talent development, customer service, technology, merchandisingwe offer a variety of training and logistics. Our editorial department is responsibledevelopment programs supporting our ethics, workplace culture and managers. For example, we require our employees to complete unconscious bias training and Code of Conduct training. In addition, all managers must complete Respect In the Workplace Training. We also offer various other training programs to employees, such as, Change & Resilience, Managing Through Change, FS90 (a course that reinforces leader habits and manager expectations for creatingnew managers) and Authentic Allyship Workshops. Additionally, in 2022 we are launching a customized Director Development Program to support leaders with the writtentools they need to succeed. We also encourage internal referrals and visual contentpostings for open roles.
Compensation and Benefits. To attract and retain qualified employees, we offer competitive compensation and comprehensive benefits, which are designed to attract, reward, and engage top talent and include standard health, dental, vision, life and disability insurance benefits as well as a 401(k) plan with company matching for our offerings. The merchant development team works with merchants to plan the offering before it is active and serves as an ongoing point of contact for the merchant over the term of an offering. Our customer service department is responsible for answering questions via phone, email, chat and social media platforms regarding purchases, shipping status, returns and other areas of customer inquiry. Our technology teamU.S. employees. In addition, Groupon is focused on the health and well-being of employees, and we have significantly expanded our wellness programming to combat burnout and support the overall health of our employees. Our wellness program includes access to mental health support and services, Global Wellness Week, which is an entire week dedicated to personal wellness programming aimed at boosting all of our physical, nutritional and mental well-being, as well as digital detox days.
Social Responsibility. Social responsibility is important to us, and we empower our employees to take part in making the communities in which we operate better places to work and live. We believe thriving local communities are good for everyone. Further, our efforts in this area support the success of our core Local business. We provide numerous opportunities for our employees to volunteer with causes they care about throughout the year and support communities through investment in local and national nonprofits focused on global issues like economic opportunity and hunger relief. In 2021, we supported more than 4,000 small businesses and entrepreneurs globally through social responsibility programming and initiatives and more than 30% of our workforce engaged in community activities through the Groupon Volunteers program.
Emerging Employee Needs: Since early 2020, our business has been significantly impacted by COVID-19. In response to the pandemic, we implemented changes in our workforce and how we work in response to the pandemic. For example, in response to employee needs and the evolving nature of work, we developed a more flexible, hybrid working approach designed to optimize collaboration across our global employee base and maintain the accountability and productivity of our performance culture. We anticipate the return of employees to the workplace in 2022 utilizing our hybrid working design, and development of new featuresour global Human Resources team will continue to support the efforts for a smooth return to a safe working environment with the health and products to enhance the customer and merchant experience, maintenancesafety of our websitesemployees being a primary consideration. Additionally, in response to challenges created by the COVID-19 pandemic, we developed and developmentlaunched a program on Building Resilience through Psychological Flexibility, which is available to all employees.
Our goal is to nurture a performance driven culture - one that will be led by our values and maintenance of our internal systems. Merchandisingfocused on agility, results and logistics personnel are responsible for managing inventory and the flow of products from suppliersaccountability. We believe that this culture is foundational to our customers.ability to drive our organization toward our long-term vision of being the destination for Local experiences. We intend to continue to focus on driving measurable results that will "show up" in our ability to attract and retain talent and build a resilient workforce well positioned to help us reach our long-term goals.
Technology
Our websites are hosted at two U.S. data centers in California and at an international data center in Ireland. Our data centers host our public-facing websites and applications, as well as our back-end business intelligence systems. We employ security practices to protect and maintain the systems located at our data centers. We are migrating our public-facing websites and applications and our back-end business intelligence systems to the cloud.

8




We have invested in intrusion and anomaly detection tools to try to recognize intrusions to our websites. We engage independent third-party Internet security firms to regularly test the security of our websites and identify vulnerabilities. In financial transactions with customers conducted on our websites and mobile applications, we use data encryption protocols to secure information while in transit. See Risk Factors for additional information relating to potential cyber threats.
Competition
Our customers and merchants are at the center of our two-sided marketplace. The quality and stability of both our customers and merchants are key to our business model. We face competition on both sides of our marketplace.
We compete with other marketplaces, and some of these marketplacesour competitors have longer operating histories, significantly greater financial, technical, marketing and other resources,resources. In addition, we compete with companies who address only specific verticals in the local experiences market, and in our Goods and Travel categories, companies who have greater scale and larger customer bases than we do. These factors may allow our competitors to benefit from their existing customer base with lower acquisition costs or to respond more quickly than we can to new or emerging technologies and changes in customer trends. These competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to build a larger subscriber base or to monetize that subscriber base more effectively than we do. We believe that after our planned exit of the Goods category, which we expect to occur by the end of 2020, we will be well-positioned to compete in our more differentiated local experiences business.
We also compete with companies that can offer alternative services for our merchants. There are companies that offer other types of advertising and promotional services to local businesses. Our merchants could choose to leverage these other platforms to attract customers to their businesses. We believe we can compete due to the access we provide our merchants to our large customer base, our trusted brand, and the investments we are making in self-service tools that will allow merchants to manage demand more effectively and better attract and retain customers.
Seasonality
Some of our offerings, particularly those within our Goods category, experienceHistorically, we experienced seasonal buying patterns mirroring that of the larger consumer retail and e-commerce markets, where demand increases during the fourth quarter holiday season. We believe thisThat seasonal pattern has affectedbeen less pronounced lately due to the de-emphasis on our businessGoods category and quarterly sequential revenue growth rates in the past and may continue to have an impact, although to a lesser extent, after exiting the Goods category. We recognized 27.6%, 30.3% and 30.7%impacts of our annual revenue during the fourth quarter of 2019, 2018 and 2017.

COVID-19.
Regulation
We are subject to a number of foreign and domestic laws and regulations that affect companies conducting business on the Internet. Additionally, those laws and regulations may be interpreted differently across domestic and foreign jurisdictions. As a company in a relatively new and rapidly innovating industry, we are exposed to the risk that many of those laws may evolve or be interpreted by regulators or in the courts in ways that could materially affect our business. Those laws and regulations may involve taxation, unclaimed property, intellectual property, product liability, travel, distribution, electronic contracts and other communications, competition, consumer protection, the provision of various online payment services, employee, merchant and customer privacy and data security or other areas.
The Credit Card Accountability Responsibility and Disclosure Act of 2009 (the "CARD Act"), as well as the laws of most states, contain provisions governing gift cards, gift certificates, stored value or pre-paid cards or coupons ("gift cards"). Groupon vouchers may be included within the definition of "gift cards" under many laws. In addition, certain foreign jurisdictions have laws that govern disclosure and certain product terms and conditions, including restrictions on expiration dates and fees, that may apply to Groupon vouchers. There are also a number of legislative proposals pending before the U.S. Congress, various state legislative bodies and foreign governments that could affect us, and our global operations may be constrained by regulatory regimes and laws in Europe and other jurisdictions outside the United States that may be more restrictive and adversely impact our business.
Various U.S. laws and regulations, such as the Bank Secrecy Act of 1970 (the "Bank Secrecy Act"), the Dodd-Frank Wall Street Reform and Consumer Protection Act, the USA PATRIOT Act and the CARD Act impose certain anti-money laundering requirements on companies that are financial institutions or that provide financial products and services. Those laws and regulations broadly define financial institutions to include money services

businesses such as money transmitters, check cashers and sellers or issuers of stored value. Requirements imposed on financial institutions under those laws include customer identification and verification programs, record retention policies and procedures and transaction reporting. We do not believe that we are a financial institution subject to those laws and regulations.
We are subject to a variety of U.S. federal, state and international laws and regulations governing consumer data. The General Data Protection Regulation ("GDPR"), which was adopted by the European Union and became effective in May 2018, requiresthe California Consumer Privacy Act (“CCPA”) which became effective January 1, 2020, and the California Privacy Rights Act (the "CPRA"), which expands on the CCPA and will go into effect in 2023, require companies to satisfy newspecific requirements regarding the handling of personal and sensitive data, including its collection, use, protection and the ability of persons whose data is stored to, correct among other things, access and/or delete such data about themselves. ComplyingThe Virginia Consumer Data Protection Act (the "CDPA") and the Colorado Privacy Act (the "CPA"), which will also go into effect in 2023 provide new data privacy rights to their respective residents. Our ongoing efforts to comply with the GDPR caused usthese laws and regulations and other relevant privacy and data protection laws and regulations, have required updates to update certain business practices and systems. Non-compliance with any privacy and data protection laws and regulations could result in significant monetary fines. For instance, non-compliance with the GDPR could result in proceedings against us by governmental entities or others and fines up to the greater of €20 million or 4% of annual global revenue. In addition,We continue to monitor developments in laws and regulations relating to privacy and consumer data, and we expect these evolving laws and regulations will continue to impact our business in the State of California adopted the California Consumer Protection Act of 2018 (“CCPA”), which became effective in January 2020 and regulates the collection and use of consumers’ data. Compliance with the CCPA is expected to cause us to make additional updates to certain business practices and systems.future.
Intellectual Property
We protect our intellectual property rights by relying on federal, state and common law rights, as well as contractual restrictions. We control access to our proprietary technology by entering into confidentiality and invention assignment agreements with our employees and contractors, and confidentiality agreements with third parties.
In addition to those contractual arrangements, we also rely on a combination of trade secrets, copyrights, trademarks, service marks, trade dress, domain names and patents to protect our intellectual property. Groupon and its related entities own a number of trademarks and service marks registered or pending in the United States and internationally. In addition, we own a number of issued patents and pending patent applications in the United States and internationally and own and have applied for copyright registrations in the United States.
Circumstances outside our control could pose a threat to our intellectual property rights and the efforts we have taken to protect our proprietary rights may not be sufficient or effective or deter independent development of equivalent or superior intellectual property rights by others. Any significant impairment of our intellectual property rights could harm our business or our ability to compete. Also, protecting our intellectual property rights is costly and time-consuming. Any unauthorized disclosure or use of our intellectual property could make it more expensive to do business and harm our operating results.
Companies in the Internet, technology and other industries as well as non-practicing entities may own large

numbers of patents, copyrights and trademarks or other intellectual property rights and may request license agreements, threaten litigation or file suit against us based on allegations of infringement or other violations of intellectual property rights. We are currently subject to, and expect to face in the future, lawsuits and allegations that we have infringed the intellectual property rights of third parties. As our business grows,evolves, we will likelymay face more claims of infringement, and may experience an adverse result which could impact our business and/or our operating results.
We have received in the past, and we anticipate we will receive in the future, communications alleging that items offered or sold through our website infringe third-party copyrights, trademarks, patents and trade names or other intellectual property rights or that we have otherwise infringed third parties’ past, current or future intellectual property rights. We may be unable to prevent third parties from offering and selling unlawful or infringing goods or goods of disputed authenticity, and we may be subject to allegations of civil or criminal liability for unlawful activities carried out by third parties through our website. We may implement measures in an effort to protect against these potential liabilities that could require us to spend substantial resources and/or to reduce revenue by discontinuing certain service offerings. Any costs incurred as a result of liability or asserted liability relating to the sale of unlawful or infringing goods or the unlawful salegoods of goodsdisputed authenticity or other infringement related claims could harm our business.

Summary Risk Factors
The following is a summary of some of the risks and uncertainties that could materially adversely affect our business, prospects, financial condition, operating results and the trading price of our common stock. You should read this summary together with the more detailed description of each risk factor contained below.
Risks Related to Our Business, Operations and Strategy
COVID-19 pandemic has, and is expected to continue to, materially affect our business, financial condition and results of operations, and any future outbreaks of new COVID-19 variants, other contagious diseases and other adverse public health developments could materially affect our business.
Our strategy may be unsuccessful and may expose us to additional risks. If our strategy does not achieve its expected benefits, there could be negative impacts to our business, financial condition and results of operations.
Our operating results may vary significantly from quarter to quarter.
Our international operations are subject to varied and evolving commercial, employment and regulatory challenges, and our inability to adapt to the diverse and changing landscapes of our international markets may adversely affect our business.
Our future success depends upon our ability to attract and retain high quality merchants and third-party business partners.
If we fail to retain our existing customers or acquire new customers, our operating results and business will be harmed.
We operate in a highly competitive industry with relatively low barriers to entry and must compete successfully in order to grow our business.
Our success is dependent upon our ability to provide a superior mobile experience for our customers and our customers' continued ability to access our offerings through mobile devices.
An increase in our refund rates or estimated liabilities with respect to unredeemed vouchers could adversely affect our financial results.
The loss of key members of our management team, or our failure to attract and retain other highly qualified personnel in the future could harm our business.
Failure to deal effectively with fraudulent transactions and customer disputes would increase our loss rate and harm our business.
We are subject to payments-related risks.
Risks Related to Technology and Cybersecurity
We rely on email, Internet search engines and mobile application marketplaces to drive traffic to our marketplace.
We may be subject to breaches of our information technology systems, which could harm our relationships with our customers, merchants, employees and third-party business partners, subject us to negative publicity and litigation, and cause substantial harm to our business or brand.
Our business depends on our ability to maintain and improve the technology infrastructure necessary to send our emails and operate our websites, mobile applications and transaction processing systems, and any significant disruption in service on our email network infrastructure, websites, mobile applications or transaction processing systems could result in a loss of customers or merchants.
As we increase our reliance on cloud-based applications and platforms to operate and deliver our products and services, any disruption or interference with these platforms could adversely affect our financial condition and results of operations.

12




Risks Related to Transactions and Investments
Acquisitions, dispositions, joint ventures and strategic investments could result in operating difficulties, dilution and other consequences.
We do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits.
Risks Related to Our Brand and Intellectual Property
We allow third parties to sell products via our site, which increases our risk of litigation and other losses.
We may be subject to substantial liability claims and damage to our brand and reputation if people or property are harmed by the products or services offered through our marketplace.
We may not be able to adequately protect our intellectual property rights or may be accused of infringing intellectual property rights of third parties.
Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our ability to expand our base of customers and merchants could be impaired and our business and operating results could be harmed.
Risks Related to Legal, Regulatory, Privacy and Tax Matters
We are involved in pending litigation and other claims and an adverse resolution of such matters may adversely affect our business, financial condition, results of operations and cash flows.
The application of certain laws and regulations, including, among other laws, the CARD Act and similar state and foreign laws, may harm our business and results of operations.
If we are required to materially increase the liability recorded in our financial statements with respect to unredeemed vouchers our results of operations could be materially and adversely affected.
Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.
Failure to comply with existing, expanding or newly enacted U.S. federal, state and international privacy laws and regulations, could adversely affect our business.
Misclassification or reclassification of our independent contractors or employees could increase our costs and adversely impact our business.
We may suffer liability as a result of information or content retrieved from or transmitted over the Internet and claims related to our service offerings.
We may have exposure to greater than anticipated tax liabilities.
The adoption of tax reform policies, including the enactment of legislation or regulations implementing changes in the tax treatment of companies engaged in Internet commerce and U.S. taxation could materially affect our financial position and results of operations.
Federal laws and regulations, such as the Bank Secrecy Act and the USA PATRIOT Act and similar foreign laws, could be expanded to include Groupon vouchers or other offerings.
State and foreign laws regulating money transmission could be expanded to include Groupon vouchers or other Groupon products or services.
Risks Related to Our Capital Structure
Our access to capital and ability to raise capital in the future may be limited, which could prevent us from growing, and our existing credit agreement could restrict our business activities.
We may not have the ability to raise the funds necessary to settle conversions of the 2026 Notes in cash, to repurchase the 2026 Notes upon a fundamental change or to repay the 2026 Notes in cash at their maturity (if not earlier converted, redeemed or repurchased), and our current and future debt may contain limitations on our ability to pay cash upon conversions of the 2026 Notes or at their maturity or to repurchase the 2026 Notes.
The terms of the 2026 Notes could delay or prevent an attempt to take over our Company.

Risks Related to Ownership of Our Common Stock
The trading price of our common stock is highly volatile.
If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research reports about our business, our share price and trading volume could decline.
We do not intend to pay dividends for the foreseeable future.

Risks Related to Our Business, Operations and Strategy
COVID-19 pandemic has, and is expected to continue to, materially affect our business, financial condition and results of operations, and any future outbreaks of new COVID-19 variants, other contagious diseases and other adverse public health developments could materially affect our business.
The ongoing COVID-19 pandemic has had a material impact on our business and results of operations. COVID-19 has resulted in significant governmental measures being implemented to control the spread of the virus, including quarantines, travel restrictions, business shutdowns and restrictions on the movement and gathering of people in the United States and abroad. Our business has been adversely affected in jurisdictions that have imposed closures of our merchants or imposed other restrictions on operations of our merchants and activities of consumers, and the continued implementation of such measures may further adversely affect our business. Even where such measures are not implemented, the perceived risk of infection or significant health risk may adversely affect our business. Further, the timing of continued global vaccination distribution and administration, vaccination rates and the long-term effectiveness of any vaccines against COVID-19 and any variants is not certain. As the pandemic has evolved, new variants of COVID-19 have continued to emerge that have proven to be highly transmissible, spreading throughout the United States and abroad causing increased uncertainty. The outbreak and the preventive or protective actions that governments or our merchants and consumers have taken and may take in the future in response to COVID-19 has resulted, and may continue to result, in periods of business disruption, reduced sales and increased refunds. Further, any future outbreaks of new COVID-19 variants, other contagious diseases and other adverse public health developments could materially affect our business. Such risks could also adversely affect consumers’ financial condition, resulting in reduced spending on our offerings and increased refunds. COVID-19 and the related restrictions may also adversely affect our ability to implement our strategy to focus on growing our local marketplace.
The impact of COVID-19 as well as our cost-saving actions, remote working environment, and other actions we have taken to attempt to address and mitigate the effects of COVID-19 on our business may lead to disruptions in our business or workforce, inability to grow and evolve our brand, reduced employee morale, engagement and productivity, increased attrition, problems retaining existing and recruiting future employees, limited resources to complete projects efficiently or on anticipated timelines, and increased workload for employees all of which could negatively impact our business, results of operations, financial condition and such disruptions could create risks to the effectiveness of our internal controls. Such disruption also could negatively impact our ability to realize the full benefits of our strategy.
These and other potential impacts of COVID-19 have and are expected to continue to adversely affect our business, financial condition and results of operations. The ultimate extent of the impact of COVID-19 (or any epidemic, pandemic or other health crisis) will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19, emerging virus variants and the effectiveness of actions taken to contain COVID-19 and address its impact. Further, we may continue to experience different or more prolonged impacts in certain locations where we operate, particularly in our International segment where restrictions have been more prolonged and stricter than in North America, and locations where surges in virus cases continue to occur or vaccination rates are low. We also have been, and may continue to be, impacted by pandemic-related supply chain issues, staffing shortages, excess demand, cost inflation and other transient issues that affect our merchants and will continue to evolve during the pandemic recovery period.
The potential effects of COVID-19 also could intensify or otherwise affect many of our other risk factors that are described in this Annual Report, including, but not limited to, risks related to the execution of our strategy, customer and merchant acquisition and retention, macroeconomic factors beyond our control, risks of doing business outside of the United States, including risks relating to the staffing and effectiveness of our centralized shared service centers, and risks related to our indebtedness. Because the COVID-19 situation is unprecedented and continuously evolving, the other potential impacts to our risk factors that are further described in this Annual Report are uncertain.

Our strategy may be unsuccessful and may expose us to additional risks. If our strategy does not achieve its expected benefits, there could be negative impacts to our business, financial condition and results of operations.
We are implementing a strategy to turn the Company into the leadinggrow our local experiences marketplace and return the Company to growth. As part of our strategy, we plan to exit our Goods category by the end of 2020. We intend to execute our strategy by focusing on fourour priorities: (i) Inventory - build high-qualityexpanding inventory and (ii) modernizing our marketplace by improving the merchant and offer density in core cities and bring merchants’ full catalogs onto our marketplace, (ii) Product - deliver a modern mobile experience for customers and new tools to help merchants grow their businesses, (iii) Brand - relaunch the Groupon brand and marketing strategy to move from deal-centric to a local experiences marketplace, and (iv) Cost - reduce our costs and right-size our spend to support our go-forward business.
We have an obligation to inform, negotiate and consult with our international workers' councils regarding plans to exit the Goods category, which may impact the timing, cost and execution of our planned exit. In particular, the consultation and negotiation process with workers' councils could be protracted and delay our anticipated timeline for fully exiting the Goods category in International. We also may incur greater than expected costs in connection with an exit of the Goods category, including employee severance, contractual termination costs, liquidation of assets, restructuring charges and write-offs or impairment of goodwill or other assets. In addition, we expect to experience internal disruption in the organization that could negatively impact our operations and financial results, including decreased productivity, employee morale and employee retention. Such disruption could be higher than expected and negatively impact our ability to realize the full benefits of our strategy and increases the costs associated with any exit of the Goods category. Further, our planned exit of the Goods category may adversely impact our Goods-Local cross-shoppers, and if such impact is significant, it could adversely affect our customer base and purchase frequency, limiting our ability to achieve the expected results from our strategy.experiences.
There are no assurances that our actions will be successful in building out a local experiences marketplace and returnreturning the Company to growth. Our efforts to execute our strategy may prove more difficult than we currently anticipate, including with respect to timing and our ability to increase high-quality density in key locations, improve our product in a way that appeals to consumers and merchants and effectively reduce costs.anticipate. Further, we may not succeed in realizing the benefits of these efforts on our anticipated timeline or at all. In addition, as we implement our strategy, COVID-19 related volatility and its impact on our merchants and customers may make it more difficult to effectively execute our strategy, including to quickly test, learn and scale initiatives relating to expanding inventory or improving the merchant and customer experiences. Further, the data we obtain during the period impacted by COVID-19 may not ultimately be indicative of merchant and customer preferences or behavior in the future. Even if fully implemented, our strategy may not result in a return to growth or the other anticipated benefits to our business, financial condition and results of operations. If we are unable to effectively execute our strategy and realize its anticipated benefits, it could negatively impact our business, financial condition and results of operations.
Our financial results may be adversely affected if we are unable to execute on our marketing strategy.
Our marketing strategy is focused on acquiring and retaining customers who we believe will have higher long-term value, activation and conversion rates, and purchase frequency. We also are focused on increasing awareness of our brand and online marketplaces and introducing consumers and merchants to new inventory. We intend to relaunch our brand in the second half of 2020 in an effort to evolve our image from deal-centric to a local experiences marketplace. Following the relaunch of our brand, we plan to employ a full-funnel marketing strategy targeting higher funnel marketing channels in addition to transactional marketing. We also expect to continue to focus on maintaining a payback period on our global marketing spend of approximately 12 to 18 months; however, there are no assurances that we will be able to achieve this result. If any of our assumptions regarding our marketing activities and strategies prove incorrect , including with respect to our full-funnel approach, payback periods and the efficiency of our marketing spend, or there are significant delays in our brand relaunch, our ability to generate revenue and gross profit from our investments may be less than we anticipated. In such case, we may need to increase marketing expenditures or


11




otherwise alter our strategy and our results of operations could be negatively impacted. Further, even if we successfully execute our marketing strategy and brand relaunch, we may not be able to drive the customer benefits expected
Our operating results may vary significantly from quarter to quarter.
Our operating results may vary significantly from quarter to quarter due to seasonality and other reasons such as the rapidly evolving nature of our business.business and other reasons, including seasonality. We believe that our ability to achieve and maintain revenue growth and profitability will depend, among other factors, on our ability to:
recover from and respond to the impact of COVID-19;
respond to macroeconomic challenges, including current or future inflation and the ability to optimize our supply to take into account consumer preferences at a particular point in time;
acquire new customers, and retain existing customers;customers and increase customer purchase frequency;
attract and retain high-quality merchants;
retain and attract key employees, including attracting and retaining talent with an appropriate level of skill and experience, including product and technology expertise, GAAP knowledge and experience to create the proper control environment for effective internal control over financial reporting;
effectively address and respond to challenges in international markets;
increase the number, variety, quality, density and relevance of offers,supply, including through third party business partners and technology integrations, as we attempt to build a local experiences marketplace;integrations;

increase booking capabilities and voucherless offerings;capabilities;
increase the awareness of, and evolve, our brand to a local experiences marketplace;
reduce costs and improvemaintain cost discipline to continue to benefit from our SG&A leverage;
performance of our Goods category following transition to a third party marketplace model;
successfully achieve the anticipated benefits of business combinations or acquisitions, strategic investments, divestitures and restructuring activities;
provide a superior customer service experience for our customers;
avoid interruptions to our services, including as a result of attempted or successful cybersecurity attacks or breaches;
respond to continuous changes in consumer and merchant use of technology;
offset declines in email, search engine optimization ("SEO")optimize and other traffic channels and further diversify our traffic channels;

15




react to challenges from existing and new competitors;
respond to seasonal changes in supply and demand; and
address challenges from existing and new laws and regulations.
In addition, our margins and profitability may depend on our inventory mix, geographic revenue mix, discount rates mix and merchant and third-party business partner pricing terms. Accordingly, our operating results and profitability may vary significantly from quarter to quarter.
If we fail to retain our existing customers or acquire new customers, our operating results and business will be harmed.
We must continue to retain and acquire customers who make purchases on our platform in order to increase profitability. Further, as our customer base evolves, the composition of our customers may change in a manner that makes it more difficult to generate revenue to offset the loss of existing customers and the costs associated with acquiring and retaining customers and to maintain or increase our customers’ purchase frequency. If customers do not perceive our offerings to be attractive or if we fail to introduce new and more relevant deals or increase awareness and understanding of the offerings on our marketplace platform, we may not be able to retain or acquire customers at levels necessary to grow our business and profitability. Further, the traffic to our websites and mobile applications, including traffic from consumers responding to our emails and SEO, has declined in recent years, such that an increasing proportion of our traffic is generated from paid marketing channels, such as search engine marketing ("SEM"). In addition, changes to search engine algorithms or similar actions are not within our control and could adversely affect traffic to our websites and mobile applications. If we are unable to acquire new customers in numbers sufficient to grow our business and offset the number of existing active customers that have ceased to make purchases, or if new


12




customers do not make purchases at expected levels, our profitability may decrease and our operating results may be adversely affected.
Our international operations are subject to varied and evolving commercial, employment and regulatory challenges, and our inability to adapt to the diverse and changing landscapes of our international markets may adversely affect our business.
Our international operations require management attention and resources and also require us to localize our services to conform to a wide variety of local cultures, business practices, laws and policies. Our international operations are subject to numerous risks, including the following:
disruption resulting from the execution of our strategy, including our planned exit from the Goods category, and ability to retain Goods-Local cross shoppers;
our ability to maintain merchant and customer satisfaction such that our marketplace will continue to attract high quality merchants;
our ability to successfully respond to macroeconomic challenges, including by optimizingthe impact of COVID-19, current or future inflation and the ability to optimize our deal mixsupply to take into account consumer preferences at a particular point in time;
political, economic and civil instability and uncertainty (including acts of terrorism, civil unrest, labor unrest, violence and outbreaks of war)war and pandemics or other disease outbreaks);
currency exchange rate fluctuations;
strong local competitors, who may better understand the local market and/or have greater resources in the local market;
different regulatory or other legal requirements (including potential fines and penalties that may be imposed for failure to comply with those requirements), such as regulation of gift cards and coupon terms, Internet services, professional selling, distance selling, bulk emailing, privacy and data protection (including GDPR), cybersecurity, business licenses and certifications, taxation (including the European Union's voucher directive, digital service tax and similar regulations)regulations and any audits), consumer protection laws including those restricting the types of services we may offer (e.g., medical-related services), banking and money transmitting, that may limit or prevent the offering of our services in some jurisdictions, cause unanticipated compliance expenses or limit our ability to enforce contractual obligations;
our ability to use a common technology platform in our North America and International segments to operate our business without significant business interruptions or delays;
difficulties in integrating with local payment providers, including banks, credit and debit card networks and electronic funds transfer systems;
different employeethe ability to quickly and employer relationshipseffectively consult and the existence and actions ofnegotiate with our international workers' councils and labor unions;trade unions on various matters including restructuring actions, strategic decisions and other business critical matters, which could result in the delay of executing key actions or product delivery and increase costs;
the local legal restrictions relating to employment and staffing;
difficulty in staffing, including attracting and retaining talent with an appropriate level of skill and experience, including product and technology expertise, GAAP knowledge and experience to create the proper control environment for effective internal control over financial reporting, developing and managing foreign operations, including through centralized shared service centers, as a result of distance, language barriers and cultural differences;
seasonal reductions in business activity;
expenses associated with localizing our products; and
differing intellectual property laws.

We are subject to complex foreign and U.S. laws and regulations that apply to our international operations, such as data privacy and protection requirements, including GDPR, the Foreign Corrupt Practices Act, the UK Anti-Bribery Act and similar local laws prohibiting certain payments to government officials, banking and payment processing regulations and anti-competition regulations, among others. The cost of complying with these various, and sometimes conflicting, laws and regulations is substantial. We have implemented and continue to implement policies and procedures to ensure compliance with these laws and regulations, however, we cannot ensure that our employees, contractors, or agents will not violate our policies. Changing laws, regulations and enforcement actions in the United States and throughout the world could harm our business. If commercial and regulatory constraints in our international markets restrict our ability to conduct our operations or execute our strategic plan, our business may be adversely affected.


13




In addition, we are subject to risks associated with the withdrawal of the United Kingdom from the European Union (“Brexit”), which occurred on January 31, 2020. Pursuant to the Withdrawal Agreement Bill, the United Kingdom will remain in the European Union's free market and customs union until December 31, 2020. On January 1, 2021, the United Kingdom will withdraw from the free market and customs union, and trade between the European Union and the United Kingdom will be subject to border controls. During the transition, the parties will negotiate a free trade agreement to manage future trade in goods and services. However, it is possible that an agreement will not be reached within the transition period, and there remains significant uncertainty about the terms of the future trade relationship between the European Union and the United Kingdom. We have significant operations in both the United Kingdom and the European Union. Our operations and that of our merchants are highly integrated across the United Kingdom and the European Union, and we are highly dependent on the free flow of labor and goods in those regions. The ongoing uncertainty concerning trade between the United Kingdom and European Union nations could negatively impact our merchant and customer relationships and financial performance. The ultimate effects of Brexit on us will depend on the timing and specific terms of any agreement the United Kingdom and the European Union reach to provide access to each other’s respective markets.
Our future success depends upon our ability to attract and retain high quality merchants and third-party business partners.
We must continue to attract and retain high quality merchants in order to increase profitability.profitability and grow our marketplace. A key priority of our strategy is to increase high-quality inventory density in core citieson our marketplace, which depends on our ability to attract and bring merchants' full catalogs onto our marketplace.retain merchants and increase volume and breadth of supply. We intend to realign our sales teams to target merchants in core cities with a new go-to-market strategy,are also focused on improving quality supply and offering them modernthe merchant experience on our platform, including improving tools available to merchants to help grow their businesses. Further, COVID-19 has negatively impacted many of our merchants, including through staffing shortages and supply chain issues, and the ultimate effect on their businesses and post-COVID recovery is uncertain. We may not be able to retain or re-acquire these merchants in the future. In addition, our Goods category utilizes a third-party marketplace model, and we may not be able to maintain vendor relationships on favorable payment terms, margins or at all. If we are not able to effectively execute our inventory initiatives,attract and retain merchants, third party partners or vendors, it could adversely affect our ability to attractbusiness and retain merchants.results of operations.
In addition, in most instances, we do not have long-term arrangements to guarantee the availability of deals that offer attractive quality, value and variety to customers or favorable payment terms to us. If merchants or third party partners decide that utilizing our services no longer provides an effective means of attracting new customers or selling their offerings, they may stop working with us or negotiate to pay us lower margins or fees. In addition, current or future competitors may accept lower margins, or negative margins, to secure merchant offers that attract attention and acquire new customers. We also may experience attrition in our merchants resulting from several factors, including losses to competitors and merchant closures or merchant bankruptcies. If we are unable to attract and retain high quality merchants and third party partners in numbers sufficient to grow our business, or if merchants and third party partners are unwilling to offer products or services with compelling terms through our marketplace, our operating results may be adversely affected.
If we fail to retain our existing customers or acquire new customers, our operating results and business will be harmed.
We must continue to retain and acquire customers who make purchases on our platform in order to increase profitability and grow our marketplace. COVID-19 has negatively impacted our ability to attract and retain customers, and the timing of recovery and the pandemic's impact on long-term customer behavior is uncertain. Although we intend to focus on re-engaging and acquiring new customers as our business recovers from COVID-19, our efforts may not be successful. Further, as our customer base evolves, the composition of our customers may change in a manner that makes it more difficult to generate revenue to offset the loss of existing customers and the costs associated with acquiring and retaining customers and to maintain or increase our customers’ purchase frequency. If customers do not perceive our offerings to be attractive or if we fail to introduce new and more relevant deals or increase awareness and understanding of the offerings on our marketplace platform, we may not be able to retain or acquire customers at levels necessary to grow our business and profitability. In addition, changes to search engine algorithms or similar actions are not within our control and could adversely affect traffic to our websites and mobile applications. If we are unable to re-engage and acquire new customers in numbers sufficient to grow our business and offset the number of customers that have ceased to make purchases, or if new customers do not make purchases at expected levels, our revenue may decrease and our operating results may be adversely affected.

We operate in a highly competitive industry with relatively low barriers to entry and must compete successfully in order to grow our business.
Competition in our industry may increase in future periods. We compete against e-commerce sites that attempt to replicate our business model, companies that offer other types of advertising and promotional services to local businesses and companies who address only specific verticals in the local experiences market. In addition to such competitors, we may experience increased competition from other large businesses who offer deals similar to ours as an add-on to their core business. We also compete with other companies that offer digital coupons through their websites or mobile applications. Further, we compete against other e-commerce companies that serve niche markets and interests, including within the local experiences market. In our Travel and Goods categories, we compete against much larger companies who have more resources and significantly greater scale. In addition, we compete with traditional offline coupon and discount services, as well as newspapers, magazines and other traditional media companies who provide coupons and discounts on products and services.
We believe that our ability to compete successfully depends upon many factors both within and beyond our control, including the following:
the continued impact of COVID-19 on our business and our ability to recover from such impact;
the size, composition and retention of our customer and merchant bases;
density and quality of our inventory;
delivery of a modern user experience for customers and modern experience and tools for merchants;
mobile penetration;
understanding local business trends;
our ability to structure deals to generate positive return on investment for merchants;
the timing and market acceptance of deals we offer, including the developments and enhancements to those deals offered by us or our competitors;
our customer and merchant service and support efforts;
selling and marketing efforts;
ease of use, performance, price and reliability of services offered either by us or our competitors;
our ability to improve customer purchase frequency and customer lifetime value;
our ability to drive traffic to our marketplace;
the number, quality and reliability of the digital coupons that can be accessed through our platform;
the quality and performance of our merchants;
our ability to cost-effectively manage our operations; and
our reputation and brand strength relative to our competitors.
Some of our competitors have longer operating histories, greater financial, marketing and other resources and larger customer bases than we do. These factors may allow our competitors to benefit from their existing customer base with lower customer acquisition costs or to respond more quickly than we can to new or emerging technologies and changes in consumer habits. Further, COVID-19 may not have had or in the future have a comparable impact on these competitors' businesses. In addition, our competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to build larger customer and/or merchant bases or generate revenue from their customer bases more effectively than we do. Our competitors may offer deals that are similar to the deals we offer or that achieve greater market acceptance than the deals we offer. This could attract customers away from our websites and mobile applications, reduce our market share and adversely impact our gross profit. In addition, we are dependent on some of our existing or potential competitors for display advertisements and other marketing initiatives to acquire new customers. Our ability to utilize their platforms to acquire new customers may be adversely affected if they choose to compete more directly with us or prevent us from using their services.

Our success is dependent upon our ability to provide a superior mobile experience for our customers and our customers' continued ability to access our offerings through mobile devices.
In the year ended December 31, 2021, over 75% of our global transactions were completed on mobile devices. While the focus on mobile is key to our long-term strategy, currently average purchase prices and conversion rates on mobile tend to be significantly lower than desktop. In order to continue to grow our mobile transactions and improve mobile conversion rates, it is critical that our applications are compatible with a range of mobile technologies, systems, networks and standards and that we provide a good, modern customer experience. Our business may be adversely affected if our customers choose not to access our offerings on their mobile devices, we are not successful in increasing mobile conversion rates or if we fail to develop applications and product enhancements with adequate functionality and a positive customer experience on a wide range of mobile devices. In addition, the success of our mobile application depends on our continued ability to distribute it through mobile application marketplaces (e.g., an app store).
An increase in our refund rates or estimated liabilities with respect to unredeemed vouchers could adversely affect our financial results.
COVID-19 has had a significant impact on refunds. A further downturn in general economic conditions or extended period of low consumer confidence (including the continued impact of and recovery from COVID-19) could also increase our refund rates. An increase in our refund rates could significantly reduce our liquidity, profitability and financial results. We estimate future refunds based on historical refund experience by category. We assess the trends that could affect our estimates on an ongoing basis and make adjustments to the refund reserve calculations if it appears that changes in circumstances, including changes to our refund policies or general economic conditions, may cause future refunds to differ from our initial estimates. Our actual level of refund claims could prove to be greater than the level of refund claims we estimate. If our refund reserves are not adequate to cover future refund claims, this inadequacy could have a material adverse effect on our financial results. In addition, we may not be able to obtain reimbursement from merchants (particularly those negatively impacted by COVID-19) for refunds that we issue, which could have an adverse effect on our financial results.
We primarily use redemption payment terms with our merchants globally, and we are required under the applicable revenue recognition standard to estimate variable consideration from unredeemed vouchers. As a result, a significant percentage of our transactions require us to use projections in order to estimate revenue and liabilities associated with unredeemed vouchers. If the estimates that we use in projecting the likelihood of vouchers being redeemed prove to be inaccurate, our liabilities with respect to unredeemed vouchers may be materially different than the amounts shown in our financial statements, and our revenue and net income could be materially affected.
The loss of key members of our management team, or our failure to attract and retain other highly qualified personnel in the future could harm our business.
In order to be successful, we must attract, retain and motivate executives and other key employees, including those in managerial, technical, accounting and sales positions. Hiring and retaining qualified executives, engineers and qualified sales representatives are critical to our success, and competition can be intense for experienced and well qualified executives and employees, particularly in recent periods. In 2020 and 2021, we experienced significant leadership changes, including the appointment of a new Chief Executive Officer in December 2021. In addition, we currently have multiple interim roles in senior management, including our Interim Chief Financial Officer and Interim Chief Accounting Officer. We need to identify and hire individuals for these permanent roles, and there are no assurances we will be able to fill these roles quickly. Furthermore, we may experience additional changes in key roles in the future. Executive leadership transitions can be time consuming, difficult to manage and could cause disruption to our business. Further, continued disruption in our business due to COVID-19 may make it more difficult to attract and retain talent. In order to attract and retain key executives and employees in a competitive marketplace, we must provide a competitive compensation package, including cash and equity-based compensation. We typically utilize restricted stock units and performance share units as our forms of share-based incentive compensation. If the anticipated value of such equity-based incentive awards does not materialize, if our equity-based compensation otherwise ceases to be viewed as a valuable benefit or if our total compensation package is not viewed as competitive, our ability to attract, retain and motivate key executives and employees could be weakened. The failure to successfully hire and retain key executives and employees or the loss of any key executives and employees could have a significant impact on our operations, including declining product identity and competitive differentiation, eroding employee morale and productivity or an inability to maintain internal controls, regulatory or other compliance related requirements.

Failure to deal effectively with fraudulent transactions and customer disputes would increase our loss rate and harm our business.
We sell a variety of offerings to consumers through our marketplace, including our vouchers and digital coupon offerings with unique identifier codes. It is possible that consumers or other third parties will seek to create counterfeit vouchers or codes, fraudulent accounts or fraudulent banking information in order to improperly purchase or redeem goods and services. While we use advanced anti-fraud technologies, criminals may attempt to circumvent our anti-fraud systems using increasingly sophisticated methods. In addition, our service could be subject to employee fraud or other internal security breaches or merchant fraud, and we may be required to reimburse customers or merchants for any funds stolen or revenue lost as a result of such breaches. If merchants are affected by buyer fraud or other types of fraud, they could also request reimbursement, or stop offering goods or services on our marketplaces.
Although we have not incurred material losses from fraud or counterfeit vouchers or digital codes in the past, we could incur material losses from such activities in future periods. Additionally, we may incur losses from claims that the customer did not authorize a purchase, from credit card fraud, from merchant fraud, from erroneous transmissions, and from customers who have closed bank accounts or have insufficient funds in them to satisfy payments. We also may incur losses as a result of purchases made with fraudulent credit card information, even if the associated financial institution approved payment of the transaction. In addition to the direct costs of any such losses, if the losses are related to credit card transactions and become excessive, they could potentially result in our losing the right to accept credit cards for payment. If we were unable to accept credit cards for payment, we would suffer substantial reductions in revenue, which would cause our business to suffer. While we have taken measures to detect and reduce the risk of fraud, these measures need continual improvement and may not be effective against new and continually evolving forms of fraud and may not timely detect fraud. If we are unable to effectively combat fraudulent transactions or if we otherwise experience increased levels of fraud or disputed credit card payments, our business could materially suffer.
We are subject to payments-related risks.
We accept payments using a variety of methods, including credit cards, debit cards and gift certificates. As we offer new payment options to customers, we may be subject to additional regulations, compliance requirements and fraud. For certain payment methods, including credit and debit cards, we pay interchange and other fees, which may increase over time and raise our operating costs and lower profitability. In addition, our credit card and other payment processors generally have broad discretion to impose receivable holdback or reserve requirements based on changes to our business model or material changes in our financial condition, and could do so in the future. Any material increase in receivable holdback or reserve requirements could have a material impact on our cash flow and available liquidity. In the event our strategy is unsuccessful or our business deteriorates significantly due to COVID-19 or other factors, these payment processors could increase holdback amounts due to concerns with our financial condition, which could adversely affect our liquidity. We rely on third parties to provide payment processing services, including the processing of credit cards and debit cards, and it could disrupt our business if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from customers or facilitate other types of online payments, and our business and operating results could be adversely affected.
We are also subject to or voluntarily comply with a number of other laws and regulations relating to money laundering, international money transfers, privacy and information security and electronic fund transfers. If we were found to be in violation of applicable laws or regulations, we could be subject to civil and criminal penalties. In addition, events affecting our third-party payment processors or our integration with them, including cyber-attacks, Internet or other infrastructure or communications impairment or other events that could interrupt the normal operation of our payment processors or our integration with them, or result in unauthorized access to customer information, could have a material adverse effect on our business.

Risks Related to Technology and Cybersecurity
We rely on email, Internet search engines and mobile application marketplaces to drive traffic to our marketplace.
The traffic to our websites and mobile applications, including from consumers responding to our emails and SEO,search engine optimization ("SEO"), has declined in recent years. As such, we must focus on diversifying our sources of traffic, including by developing sources of traffic in addition to email and SEO and optimizing the efficiency of our marketing spending. If we are not able to diversify our sources of traffic and acquire and retain customers efficiently, our business and results of operations could be adversely affected.
Email continues to be a significant source of organic traffic for us. If email providers or Internet service providers implement new or more restrictive email or content delivery or accessibility policies, including with respect to net neutrality, it may become more difficult to deliver emails to our customers or for customers to access our site and services. For example, certain email providers, including Google, categorize our emails as "promotional," and these emails are directed to an alternate, and less readily accessible, section of a customer's inbox. If email providers materially limit or halt the delivery of our emails, or if we fail to deliver emails to customers in a manner compatible with email providers’ email handling or authentication technologies, our ability to contact customers through email could be significantly restricted. In addition, if we are placed on "spam" lists or lists of entities that have been involved in sending unwanted, unsolicited emails, our operating results and financial condition could be substantially harmed. In addition, Apple released iOS 15, which updated its privacy practices and policies, limiting the ability of email senders to track recipients' email activity. Such actions, and similar actions in the future, could adversely impact our email open rates, our ability to drive traffic to our marketplace and the effectiveness and efficiency of our email marketing, any of which could have a negative impact on our business and results of operations.
We also rely heavily on Internet search engines to generate traffic to our websites, principally through SEMsearch engine marketing ("SEM") and SEO. The number of consumers we attract from search engines to our platform is due in large part to how and where information from, and links to, our websites are displayed on search engine results pages. The display, including rankings, of search results can be affected by a number of factors, many of which are not in our control and may


14




change at any time. Search engines frequently update and change the logic that determines the placement and display of the results of a user’s search, such that the purchased or algorithmic placement of links to our websites can be negatively affected. In addition, a search engine could, for competitive or other purposes, alter its search algorithms or results causing our websites to place lower in search query results. If a major Internet search engine changes its algorithms in a manner that negatively affects the search engine ranking it could create additional traffic headwinds for us and negatively affect our results of operations.
Furthermore, web browser providers have implemented and may continue to implement changes in their browsers. For example, Google has indicated it intends to further restrict the use of third-party cookies in its Chrome browser, consistent with similar actions taken by the owners of other browsers. Such actions may adversely impact our ability to successfully drive traffic to our marketplace and limit the effectiveness and efficiency of our marketing.
We also rely on mobile marketplace operators (i.e., app store operators) to drive downloads of our mobile application. If any mobile marketplace operator determines that our mobile application is non-compliant with its vendor policies, the operator may revoke our rights to distribute through its marketplace or refuse to permit a mobile application update at any time. These operators may also change their mobile application marketplaces or mobile operating systems in a way that negatively affects the prominence of, effectiveness of, or ease with which users can access, our mobile application. For example, Apple made changes to iOS and its App Tracking Transparency policy, which now requires apps to get a user’s opt-in permission before tracking or sharing the user’s data across apps or websites owned by companies other than the app’s owner. Such actions, mayand similar actions in the future, could adversely impact our ability to drive traffic to our mobile application and marketplace, the ability of customers to access our offerings through mobile devices and the effectiveness and efficiency of our marketing, any of which could have a negative impact on our business and results of operations.
Email, Internet service and web browser providers, as well as Internet search engines and mobile marketplace operators continue to remain focused on concerns surrounding user and data privacy and protection. Any of these parties may take additional action in the future to respond to such concerns, which could have a negative impact on our business and results of operations.

21




We may be subject to breaches of our information technology systems, which could harm our relationships with our customers, merchants, employees and third-party business partners, subject us to negative publicity and litigation, and cause substantial harm to our business or brand.
In operating a global online business, we and our third-party service providers maintain significant proprietary information and manage large amounts of personal data and confidential information about our employees, customers and merchants. We and such service providers are at constant risk of cyber-attacks or cyber intrusions via the Internet, computer viruses, break-ins, malware, ransomware, phishing attacks, hacking, denial-of-service attacks or other attacks and similar disruptions from the unauthorized use of or access to computer systems (including from internal and external sources). These types of incidents have become morecontinue to be prevalent and pervasive across industries, including in our industry, and such attacks on our systems have occurred in the past and are expected to occur in the future. In addition, we expect the amount and sophistication of the perpetrators of these attacks to continue to expand, which could include nation-state actors. Further, we believe that we are a compelling target for such attacks as a result of the high profile of our brand and the amount and type of information we maintain relating to our customers and merchants. Any such incident could lead to interruptions, delays or website outages, causing loss of critical data or the unauthorized disclosure or use of personally identifiable or other confidential information. Further, third party service providers we utilize in our operations could be targeted by such cyber attacks, which could indirectly impact our business, by way of similar adverse consequences to a direct attack depending on the type of service.
Any failure to prevent or mitigate cybersecurity breaches or other improper access to, or disclosure of, our data or confidential information, including non-public financial information, could result in the loss or misuse of such data or information, negatively impacting customers’, merchants’, employees’ and third-party business partners' confidence in the security of our services and potentially resulting in significant customer or merchant attrition, a decline in customer purchase frequency, litigation and/or regulatory investigations, and/or damage to our brand and reputation.
Our risk and exposure to these matters remains heightened because of, among other things, the evolving nature of these threats, our prominent size and scale, the large number of transactions that we process, our geographic footprint and international presence, our use of open source software, the complexity of our systems, the maturity of our systems, processes and risk management framework, our number of employees, the location of our businesses and data storage facilities, the jurisdictions in which we operate and the various and evolving laws and regulatory schemes governing data and data protection applicable to us, the extent to which our current systems, controls, processes and practices permit us to detect, log and monitor security events, our use of cloud based technologies and the outsourcing of some of our business operations.
Although cybersecurity and the continued development and enhancement of our controls, processes and practices designed to protect our systems, computers, software, data and networks from attack, damage or unauthorized access are a high priority for us, our activities and investment may not be deployed quickly enough or successfully protect our systems against all vulnerabilities, including technologies developed to bypass our security measures or zero day vulnerabilities. In addition, outside parties may attempt to fraudulently induce employees, merchants or customers to disclose access credentials or other sensitive information in order to gain access to our systems and networks. We also may be subject to additional vulnerabilities as we utilize third parties to provide various services for our operations (e.g., cloud services) and integrate the systems, computers, software and data of acquired businesses and third-party business partners into our networks and separate the systems, computers, software and data of disposed businesses from our networks.
We maintain a cybersecurity risk management program that is overseen by our Vice President,Chief Information Security who reports directly to our Chief Technology Officer. Our Vice President,Chief Information Security Officer regularly reports


15




to the Audit Committee on the state of our cybersecurity program and provides updates on cybersecurity matters. We also conduct an annual cybersecurity review with our Board of Directors.. As part of our cybersecurity risk management program, we employ security practices to protect and maintain the systems located at our data centers and hosting providers, invest in intrusion, anomaly, and vulnerability detection tools and engage third-party security firms to test the security of our websites and systems. In addition, we regularly evaluate and assess our systems and the controls, processes and practices to protect those systems and also conduct penetration testing against our own system. The evaluations, assessments and testing identify areas of potential weakness in, and suggested improvements to, the maturity of our systems, processes, and risk management framework as well as vulnerabilities in those systems, processes, and risk management framework that could be attacked and exploited to access and acquire proprietary and confidential information, including information about our customers and merchants. There are no assurances that our cybersecurity risk mitigation program or actions and investments to improve the maturity of our systems, processes

22




and risk management framework or remediate vulnerabilities will be sufficient or completed quickly enough to prevent or limit the impact of any cyber intrusion.intrusion or related attack. In addition, in the future we may be required to expend significant additional resources to modify or enhance our protective measures, controls and systems or to improve the maturity of our systems, processes and risk management framework, or investigate or remediate any information security vulnerabilities. These improvements, modifications and enhancements may take significant time to implement. Further, the sophistication of potential attacks or the capabilities of our systems and processes may not permit us to detect the occurrence of cyber incidents until significant data loss has occurred. Moreover, because the techniques used to gain access to or sabotage systems often are not recognized until launched against a target, we may be unable to anticipate the methods necessary to defend against these types of attacks and we cannot predict the extent, frequency or impact these problems may have on us. Any actual breach, the perceived threat of a breach or a perceived breach, could cause our customers, merchants, card brandsemployees and payment card processors to cease doing business with us or do business with us less frequently, subject us to lawsuits (including claims for damages), investigations, regulatory fines or other action or liability or damage to our brand and reputation, which would harm our business, financial condition and results of operations.
We operate in a highly competitive industry with relatively low barriers to entry and must compete successfully in order to grow our business.
Competition in our industry may increase in future periods. A number of e-commerce sites that attempt to replicate our business model operate around the world. We also compete against companies that offer other types of advertising and promotional services to local businesses. In addition to such competitors, we may experience increased competition from other large businesses who offer deals similar to ours as an add-on to their core business. We also compete with other companies that offer digital coupons and/or card-linking services through their websites or mobile applications. Further, we compete against other e-commerce companies that serve niche markets and interests, including within the local experiences market. In some of our categories, such as Travel, we compete against much larger companies who have more resources and significantly greater scale. In addition, we compete with traditional offline coupon and discount services, as well as newspapers, magazines and other traditional media companies who provide coupons and discounts on products and services.
We believe that our ability to compete successfully depends upon many factors both within and beyond our control, including the following:
the size, composition and retention of our customer base and the number of merchants we feature;
quality of our inventory;
delivery of a modern user experience for customers and tools to help merchants grow their businesses;
mobile penetration;
understanding local business trends;
our ability to structure deals to generate positive return on investment for merchants;
the timing and market acceptance of deals we offer, including the developments and enhancements to those deals offered by us or our competitors;
our customer and merchant service and support efforts;
selling and marketing efforts;
ease of use, performance, price and reliability of services offered either by us or our competitors;


16




our ability to improve customer purchase frequency and customer lifetime value;
our ability to drive traffic to our marketplace;
the number, quality and reliability of the digital coupons that can be accessed through our platform;
the quality and performance of our merchants;
our ability to cost-effectively manage our operations; and
our reputation and brand strength relative to our competitors.
Many of our current and potential competitors have longer operating histories, greater financial, marketing and other resources and larger customer bases than we do. These factors may allow our competitors to benefit from their existing customer base with lower customer acquisition costs or to respond more quickly than we can to new or emerging technologies and changes in consumer habits. In addition, our competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to build larger customer and/or merchant bases or generate revenue from their customer bases more effectively than we do. Our competitors may offer deals that are similar to the deals we offer or that achieve greater market acceptance than the deals we offer. This could attract customers away from our websites and mobile applications, reduce our market share and adversely impact our gross profit. In addition, we are dependent on some of our existing or potential competitors for display advertisements and other marketing initiatives to acquire new customers. Our ability to utilize their platforms to acquire new customers may be adversely affected if they choose to compete more directly with us or prevent us from using their services.
Our success is dependent upon our ability to provide a superior mobile experience for our customers and our customers' continued ability to access our offerings through mobile devices.
In the year ended December 31, 2019, over 75% of our global transactions were completed on mobile devices. Additionally, our mobile application has been downloaded over 200 million times as of December 31, 2019. While the focus on mobile is key to our long-term strategy, currently average purchase prices and conversion rates on mobile tend to be significantly lower than desktop. In order to continue to grow our mobile transactions and improve mobile conversion rates, it is critical that our applications are compatible with a range of mobile technologies, systems, networks and standards and that we provide a good customer experience. Further, we have been developing and testing a number of product features that are intended to make our offerings easier to use for customers and merchants. We also are working on a next-generation mobile application that we plan to launch in the second quarter of 2020. Our business may be adversely affected if our customers choose not to access our offerings on their mobile devices, we are not successful in increasing mobile conversion rates or if we fail to develop applications and product enhancements with adequate functionality and a positive customer experience on a wide range of mobile devices. In addition, the success of our mobile application depends on our continued ability to distribute it through mobile application marketplaces (e.g., an app store).
Our business depends on our ability to maintain and improve the technology infrastructure necessary to send our emails and operate our websites, mobile applications and transaction processing systems, and any significant disruption in service on our email network infrastructure, websites, mobile applications or transaction processing systems could result in a loss of customers or merchants.
Customers access our marketplaces through our websites and mobile applications, as well as via emails that are often targeted by location, purchase history and personal preferences. Customers can also access our deal offerings indirectly through third-party search engines. Our reputation and ability to acquire, retain and serve our current and potential customers are dependent upon the reliable performance of our websites, mobile applications, email delivery and transaction processing systems and the underlying network infrastructure. Our systems may not be adequately designed with the necessary reliability and redundancy to avoid performance delays or outages that could be prolonged and harmful to our business. If our websites or mobile applications are unavailable when users attempt to access them, or if they do not load as quickly as expected, users may not return as often in the future, or at all. As our customer base and the amount of information shared on our websites and mobile applications continue to grow, we will need an increasing amount of network capacity and computing power. We have spent and expect to continue to spend substantial amounts on data centers and equipment, cloud-based technology and related network infrastructure and services to handle the traffic on our websites and mobile applications and to help shorten the time of or prevent system interruptions. The operation of these systems is expensive and complex and could result in operational failures. While resiliency and redundancy are considerations in the design and operation of Groupon's systems, interruptions, delays


17




or failures in these systems, whether due to earthquakes, adverse weather conditions, other natural disasters, power loss, computer viruses, cybersecurity attacks, physical break-ins, terrorism, errors in our software or otherwise, could be prolonged and could affect the security or availability of our websites and applications, and prevent our customers from accessing our services. If we do not maintain or expand our network infrastructure successfully or if we experience operational failures or prolonged disruptions or delays in the availability of our systems, or a significant search engine, we could lose current and potential customers and merchants, which could harm our operating results and financial condition.
In addition, a portion of our network infrastructure is hosted by third-party providers. We also rely on a variety of tools and third-party commercial partners to provide certain services and offerings (e.g., booking and ticketing tools). Any disruption or failure of these providers, tools and/or other third parties to handle existing or increased traffic and transactions could significantly harm our business. Any financial or other difficulties these providers face may adversely affect our business, and we exercise little control over these providers, which increases our vulnerability to problems with the services they provide.
Our business is exposed to risks associated with our voucherless offerings.
We are developing and scaling voucherless offerings, which includes working to significantly increase the number of bookable offerings on our marketplace. AlthoughAs we believe that voucherless offerings have the potential to increase customer purchase frequency and generate revenue and gross profit growth over the long term, there are no assurances that we will be able to scale our voucherless offerings or that these offerings will be successful in increasing customer purchase frequency or revenue or gross profit growth, if and when scaled. If we are unable to grow the number of and scale voucherless offerings on our marketplace, our results of operations may be adversely affected.
In addition, we currently depend on third party business partners and technology integrations for many of our voucherless offerings. If we are unable to increase our third-party voucherless offeringsreliance on cloud-based applications and platforms to operate and deliver our products and services, any disruption or successfully complete the associated technology integrations, the quality of our supply and customer experience may be negatively impacted and decrease whichinterference with these platforms could adversely affect our financial condition and results of operations.
We rely on cloud-based applications and platforms for critical business operations and financial condition. Furthermore,functions. We also are migrating a significant portion of our abilitycomputing infrastructure to provide card linked offers in which customers earn cash back on their credit card statements depends, in part,third party hosted cloud-based computing platforms. If we are not able to complete this migration on our arrangements with card brand networks.expected timeline, we could incur additional costs. Further, these migrations can be risky and may cause disruptions to the availability of our products due to service outages, downtime or other unforeseen issues that could increase our costs. We also may be subject to additional risk of cybersecurity breaches or other improper access to our data or confidential information during or following migrations to cloud-based computing platforms. In addition, cloud computing services may operate differently than

23




anticipated when introduced or when new versions or enhancements are released. As we increase our reliance on cloud-based computing services, our exposure to damage from service interruptions may increase. In the event any card brand networksuch issues arise, it may be difficult for us to switch our operations from our primary cloud-based providers to alternative providers. Further, any such transition could involve significant time and expense and could negatively impact our ability to deliver our products and services, which could harm our financial condition and results of operations.
Risks Related to Transactions and Investments
Acquisitions, dispositions, joint ventures and strategic investments could result in operating difficulties, dilution and other consequences.
We routinely evaluate and consider a wide array of potential strategic transactions, including acquisitions and dispositions of businesses, joint ventures, technologies, services, products and other assets and minority investments. The pursuit and consummation of such transactions can result in operating difficulties, dilution, management distraction and other potentially adverse consequences. In the past, we have acquired and divested a number of companies and may complete additional transactions in the future.
Acquisitions involve significant risks and uncertainties, including uncertainties as to the future financial performance of the acquired business and the performance of acquired customers, valuation of the acquired business and integration risks such as difficulties integrating acquired personnel into our business, the potential loss of key employees, customers or suppliers, difficulties in integrating different computer, payment and accounting systems and exposure to unknown or unforeseen liabilities of acquired companies. In addition, the integration of an acquisition could divert management's time and our resources. If we pay for an acquisition or a minority investment in cash, it would reduce our cash available for operations or cause us to incur debt, and if we pay with our stock, it could be dilutive to our stockholders. Additionally, we do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits. Our current investments include non-controlling equity interests in SumUp Holdings S.a.r.l., Monster Holdings LP and Nearby Pte Ltd, as well as other less significant investments. Currently there is no longer supportspublic market for the securities of any such entity, and we may not have rights with respect to transactions involving any such entity. Dispositions and attempted dispositions also involve significant risks and uncertainties, such as the risk of destabilizing the applicable operations, the loss of key personnel, the terms and timing of any dispositions, the ability to obtain necessary governmental or regulatory approvals, post-disposal disputes and indemnification obligations and risks and uncertainties with respect to the separation of disposed operations, including, for example, transition services, access by purchasers to certain of our card-linked offerings, imposes significant restrictionssystems and tools during transition periods, the migration of data and separation of systems, data privacy matters and misuse of trademarks and intellectual property. We may be unable to successfully complete potential strategic transactions or dispositions on a timely basis or at all, or we may not realize the anticipated benefits of any of our strategic transactions or dispositions (including any transactions involving minority investments) in the time frame expected or at all.
We do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits.
We currently hold non-controlling minority investments in entities, including SumUp Holdings S.a.r.l., Monster Holdings LP and Nearby Pte Ltd, and we may make additional strategic minority investments in the future. Such minority investments inherently involve a lesser degree of control over business operations, thereby potentially increasing the financial, legal, operational and/or compliance risks associated with the investments. Other investors in these entities may have business goals and interests that are not aligned with ours, or may exercise their rights in a manner in which we do not approve. These circumstances could lead to delayed decisions or disputes and litigation with those other investors, all of which could have a material adverse impact on our offeringsreputation, business, financial condition and results of operations.
If these entities seek additional financing, such financing or deal structuresother transactions may result in further dilution of our ownership stakes and such transactions have and in the future may occur at lower valuations than the investment transactions through which we acquired such interests, which could significantly decrease the fair values of our investments in those entities. Alternatively, if any such financing or other transactions occur at higher valuations in the future, we may not be able to realize the potential benefits of such higher valuation. In addition, the lack of availability of financing on commercially reasonable terms or a decline in the business performance, financial condition and competitive environment of any of our minority investments could result in lower financial results or

Risks Related to Our Brand and Intellectual Property
We purchase and sell some products from indirect suppliers and allow third parties to sell products via our site, and services, which increaseincreases our risk of litigation and other losses.
We source merchandise both directly from brand owners and indirectly from retailers andOur Goods category is operated on a third-party distributors, andmarketplace model in which we often take title to the goods before we offer them for sale to our customers. Further, some brand owners, retailers and third- party distributors may be unwilling to offer products for sale on the Internet or through Groupon in particular, which could have an adverse impact on our ability to source and offer popular products. We also allow third party merchants to sell products to our customers via our marketplace platform.platforms. By selling merchandise sourced fromallowing third parties other than the brand owners, and allowing the sale of merchandise by third parties,to sell products on our platform, we are subject to an increased riskintellectual property and other risks, including that the merchandise may be damaged or of disputed authenticity, obtained or sourced outside of the rights holder's established distribution channels or damaged, which could result in potential liability under applicable laws, regulations, agreements and orders and increase the amount of returned merchandise or customer refunds. Further, we may be found to be directly liable for actions by third party merchants who sell goods on our site. In addition, brand owners or regulators may take legal action against us. Even if we prevail, any such legal action could result in costly litigation, generate adverse publicity for us, and have a material adverse impact on our business, financial condition, results of operations, brand and reputation. Further, in any such matter, we may not be entitled to indemnification from our supplier orthe third-party merchant, or able to effectively enforce the supplier’s or merchant’s contractual indemnification obligations.
We may be subject to substantial liability claims and damage to our brand and reputation if people or property are harmed by the products or services offered through our marketplace.
Some of the products and services offered through our marketplace may expose us to liability claims relating to personal injury, death, negligence, intentional misconduct, assault, abuse or environmental or property damage. Certain merchants and third parties sell products and offer services using our marketplace that based on the type of product or service, may increase our exposure to substantial claims and litigation, especially if these merchants or


18




third-party sellers do not have sufficient protection from such claims.claims or ability to pay for any judgments, liens, or fines that may be assessed. Although we believe we are not liable for the goods or services that merchants or third-parties offer through our marketplace, there is no assurance that a court would rule in our favor on such issues. Further, while we maintain liability insurance, we cannot be certain our coverage will apply to the claims at issue, be adequate for liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all. In addition, some of our agreements with vendors, merchants and third-party sellers do not indemnify us from certain liability and costs or we may not be able to effectively enforce our contractual indemnification rights. Claims relating to products or services offered through our marketplace also could result in significant damage to our brand and reputation regardless of whether we are ultimately liable for any such claims.
Our processes and procedures for onboarding merchants and third-party sellers also may expose us to liability claims or damage to our brand and reputation if the processes or procedures are deemed inadequate. Additionally, while we maintain multiple channels through which our customers can submit feedback or complaints about their experiences with merchants and other third-party sellers on our platform, because our customers often deal directly with the sellers, pertinent feedback may not be provided to us. Moreover, our evaluation of any customer feedback or complaints we receive is subjective based on the information, which is sometimes very limited, that our customers provide, and we may not take, or be able to take, action in response to feedback or complaints. If our systems and procedures with respect to any such feedback or complaints are determined to be inadequate or any action or inaction is found to be inadequate, including, by way of example, not discontinuing on a timely basis offers of deals with merchants or sellers that have been the subject of material complaints, we could face substantial additional liability and damage to our brand and reputation for the misconduct of such merchants or third-party sellers.
We are subject to inventory management and order fulfillment risks as a result of our Goods category.

We purchase a portionmay not be able to adequately protect our intellectual property rights or may be accused of the merchandise that we offer for saleinfringing intellectual property rights of third parties.
We regard our trademarks, service marks, copyrights, patents, trade dress, trade secrets, proprietary technology, merchant lists, subscriber lists, sales methodology and similar intellectual property as critical to our customers. The demand for products can change for a variety of reasons, including customer preference, quality, seasonality,success, and customers' perception ofwe rely on trademark, copyright and patent law, trade secret protection and confidentiality and/or license agreements with our employees and others to protect our proprietary rights. Effective intellectual property protection may not be available in every country in which our deals are made available. We also may not be able to acquire or maintain appropriate domain names or trademarks in all countries in which we do business. Furthermore, regulations governing domain names may not protect our trademarks and similar proprietary rights. We may be unable to prevent third parties from acquiring and using domain names or trade names that are similar to, infringe upon or diminish the value of purchasingour trademarks and other proprietary rights. We may be unable to prevent third parties from using and registering our trademarks, or trademarks that are similar to, or diminish the product throughvalue of, our trademarks in some countries.
We may not be able to discover or determine the extent of any unauthorized use of our proprietary rights. Third parties that license our intellectual property rights also may take actions that diminish the value of our proprietary rights or reputation. The protection of our intellectual property may require the expenditure of significant financial and managerial resources. Moreover, the steps we take to protect our intellectual property may not adequately protect our rights or prevent third parties from infringing or misappropriating our proprietary rights. We are currently subject to multiple lawsuits and disputes related to our intellectual property and service offerings. We may in the future be subject to additional litigation and disputes. The costs of engaging in such litigation and disputes are considerable, and there can be no assurances that favorable outcomes will be obtained.
We are currently subject to third-party claims that we infringed upon proprietary rights or trademarks and expect to be subject to additional claims in the future. Such claims, whether or not meritorious, may result in the expenditure of significant financial and managerial resources, injunctions against us or the payment of damages by us. We may need to obtain licenses from third parties who allege that we have infringed their rights, but such licenses may not be available on terms acceptable to us or at all. These risks have been amplified by the increase in third parties whose sole or primary business is to assert such claims.
Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our ability to expand our base of customers and merchants could be impaired and our business and operating results could be harmed.
We believe that the brand identity that we have developed has significantly contributed to the success of our business. We also believe that maintaining and enhancing the "Groupon" brand is critical to expanding our base of customers and merchants. In addition, maintaining and enhancing our brand may require us to make substantial additional investments over time and these investments may not be successful. If we fail to promote, maintain and protect the "Groupon" brand, our business, operating results and financial condition may be adversely affected. We anticipate that, as the local experiences market becomes increasingly competitive, maintaining and enhancing our brand may become more difficult and expensive. Maintaining and enhancing our brand will depend largely on our ability to continue to provide reliable, trustworthy and high quality inventory on our marketplace, which we may not do not adequately predict customer demand and efficiently manage inventory, we could have either an excesssuccessfully.
We receive a high degree of media coverage around the world. Unfavorable publicity or a shortage of inventory, either of which would adversely impact our business. Delays or inefficiencies in our processes, or thoseconsumer perception of our third-party logistics providerswebsites, mobile applications, practices or third-party sellers, also could subject us to additional costs, as well as customer dissatisfaction, whichservice offerings, or the offerings of our merchants or their products, could adversely affect our business.

As a result, our business, financial condition and results of the Goods category, we may have excess inventory that we are forcedoperations could be materially and adversely affected.
Risks Related to sell at a discount or loss, which could increase overall costs of executing our go-forward strategy.Legal, Regulatory, Privacy and Tax Matters
We are involved in pending litigation and other claims and an adverse resolution of such litigationmatters may adversely affect our business, financial condition, results of operations and cash flows.
We are involved from time to time in litigation regarding, among other matters, patent and other intellectual property claims, consumer privacyclaims, contract disputes with merchants and vendors, employment issues.claims, and

26




securities law claims. Litigation, dispute resolution proceedings and investigations can be expensive, time-consuming and disruptive to normal business operations. The results of complex legal proceedings are often uncertain and difficult to predict. An unfavorable outcome with respect to any of these lawsuits or claims could have a material adverse effect on our business, financial condition, results of operations and cash flows. For additional information, regarding these and other lawsuits in which we are involved, see Item 8, Note 11,10, Commitments and Contingencies, to the consolidated financial statements.
An increaseThe ongoing COVID-19 pandemic may also result in additional litigation including disputes with merchants, customers, vendors, and others over refunds, payments, and contract terms. We may also be the target of tort or negligence claims relating to incidents, injuries or illnesses incurred by customers visiting merchants. Although we disclaim legal liability for such claims and advise all of our customers that the merchants are solely responsible to purchasers for the care and quality of the advertised goods and services, there is no assurance that a court would rule in our refund rates or estimated liabilitiesfavor on such issues. We also hold indemnity rights with respect to unredeemed vouchersmerchants in relation to any such claims, but there is no assurance that merchants will be sufficiently capitalized to cover all incurred losses.
Although we maintain insurance, we cannot be certain our coverage will apply to the claims at issue, be adequate for any liability incurred or continue to be available to us on economically reasonable terms, or at all. The cost of insurance, including directors and officer insurance, errors and omission insurance, product liability, general liability insurance and other types of policies, has increased and could adversely affect our profitabilityincrease further at any time or net income.
As we expand our product offerings and inventory density, our customer refund rates may exceed historical levels. A downturn in general economicbecome more limited based on market conditions or extended periodother circumstances outside of low consumer confidence (e.g, continued UK macroeconomic conditions) could also increase our refund rates. An increase in our refund rates could significantly reduce our liquiditycontrol. Furthermore, certain insurance coverages may not be available for specific risks faced by us. Insurance premium increases and profitability. We estimate future refunds utilizing a statistical model that incorporates historical refund experience, including the relativeincreased risk due to lack of refunds based on deal category. Our actual level of refund claims could prove to be greater than the level of refund claims we estimate. If our refund reserves are not adequate to cover future refund claims, this inadequacyavailability, reduced coverage or increased deductibles could have a material adverse effect on our profitability. In addition, we may not be able to obtain reimbursement from merchants for refunds that we issue, which could have an adverse effect on our liquidity and profitability.
In recent periods, we have increased our use of redemption payment terms with our North America merchants. In addition, the revenue recognition standard that we adopted in 2018 requires us to estimate variable consideration


19




from unredeemed vouchers. As a result, a greater percentage of our transactions in North America than in prior periods will require us to use projections in order to estimate revenue and liabilities associated with unredeemed vouchers. If the estimates that we use in projecting the likelihood of vouchers being redeemed prove to be inaccurate, our liabilities with respect to unredeemed vouchers may be materially higher than the amounts shown in our financial statements, and our net income could be materially and adversely affected.
The loss of one or more key members of our management team, or our failure to attract and retain other highly qualified personnel in the future could harm our business.
In order to be successful, we must attract, retain and motivate executives and other key employees, including those in managerial, technical and sales positions. Hiring and retaining qualified executives, engineers and qualified sales representatives are critical to our success, and competition for experienced and well qualified employees can be intense. Further, disruption in our business due to the implementation of our strategy, including the planned exit of our Goods category, may make it more difficult to attract and retain talent. In order to attract and retain executives and other key employees in a competitive marketplace, we must provide a competitive compensation package, including cash and equity-based compensation. We currently utilize restricted stock units and performance share units as our forms of share-based incentive compensation. If the anticipated value of such equity-based incentive awards does not materialize, if our equity-based compensation otherwise ceases to be viewed as a valuable benefit or if our total compensation package is not viewed as competitive, our ability to attract, retain and motivate executives and key employees could be weakened. The failure to successfully hire executives and key employees or the loss of any executives and key employees could have a significant impact on our operations.
Acquisitions, dispositions, joint ventures and strategic investments could result in operating difficulties, dilution and other consequences.
We routinely evaluate and consider a wide array of potential strategic transactions, including acquisitions and dispositions of businesses, joint ventures, technologies, services, products and other assets and minority investments. The pursuit and consummation of such transactions can result in operating difficulties, dilution, management distraction and other potentially adverse consequences. In the past, we have acquired and divested a number of companies and may complete additional transactions in the future.
Acquisitions involve significant risks and uncertainties, including uncertainties as to the future financial performance of the acquired business and the performance of acquired customers, valuation of the acquired business and integration risks such as difficulties integrating acquired personnel into our business, the potential loss of key employees, customers or suppliers, difficulties in integrating different computer, payment and accounting systems and exposure to unknown or unforeseen liabilities of acquired companies. In addition, the integration of an acquisition could divert management's time and our resources. If we pay for an acquisition or a minority investment in cash, it would reduce our cash available for operations or cause us to incur debt, and if we pay with our stock, it could be dilutive to our stockholders. Additionally, we do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits. Dispositions and attempted dispositions also involve significant risks and uncertainties, such as the risk of destabilizing the applicable operations, the loss of key personnel, the terms and timing of any dispositions, the ability to obtain necessary governmental or regulatory approvals, post-disposal disputes and indemnification obligations and risks and uncertainties with respect to the separation of disposed operations, including, for example, transition services, access by purchasers to certain of our systems and tools during transition periods, the migration of data and separation of systems, data privacy matters and misuse of trademarks and intellectual property. We may be unable to successfully complete potential strategic transactions or dispositions on a timely basis or at all, or we may not realize the anticipated benefits of any of our strategic transactions in the time frame expected or at all.
We do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits.
We currently hold non-controlling minority investments in Monster Holdings LP ("Monster LP") and other entities and we may make additional strategic minority investments in the future. Such minority investments inherently involve a lesser degree of control over business operations, thereby potentially increasing the financial, legal, operational and/or compliance risks associated with the investments. Other investors in these entities may have business goals and interests that are not aligned with ours, or may exercise their rights in a manner in which we do not approve. These circumstances could lead to delayed decisions or disputes and litigation with those other investors, all of which could have a material adverse impact on our reputation, business, financial condition, and results of operations.


20




If Monster LP or other entities seek additional financing, such financing transactions may result in further dilution of our ownership stakesoperations and such transactions have and in the future may occur at lower valuations than the investment transactions through which we acquired such interests, which could significantly decrease the fair values of our investments in those entities. Additionally, if Monster LP or other entities are unable to obtain any such financing, those entities could need to significantly reduce their spending in order to fund their operations. Such actions as well as a decline in the business performance, financial condition and competitive environment of an entity likely would result in reduced growth forecasts, which also could significantly decrease the fair values of our investments in those entities. Further, we have made an irrevocable election to account for our investments in Monster LP and other entities at fair value with changes in fair value reported in earnings. Our election to apply fair value accounting to those investments has and may continue to cause fluctuations in our earnings from period to period.cash flows.
The application of certain laws and regulations, including, among other laws, the CARD Act and similar state and foreign laws, may harm our business and results of operations.
The application of certain laws and regulations to vouchers is uncertain. Vouchers may be considered gift cards, gift certificates, stored value cards or prepaid cards and therefore governed by, among other laws, the CARD Act, and state laws governing gift cards, stored value cards and coupons, and, in certain instances, potentially subject to unclaimed and abandoned property laws. Other foreign jurisdictions have similar laws in place, in particular European jurisdictions where the European E-Money Directive regulates the business of electronic money institutions. Many of these laws contain provisions governing the use of gift cards, gift certificates, stored value cards or prepaid cards, including specific disclosure requirements and prohibitions or limitations on the use of expiration dates and the imposition of certain fees. For example, if vouchers are subject to the CARD Act and are not included in the exemption for promotional programs, it is possible that the purchase value, which is the amount equal to the price paid for the voucher, or the promotional value, which is the add-on value of the voucher in excess of the price paid, or both, may not expire before the later of (i) five years after the date on which the voucher was issued; (ii) the voucher’s stated expiration date (if any); or (iii) a later date provided by applicable state law. In the event that it is determined that vouchers sold through our platform are subject to the CARD Act or any similar state or foreign law or regulation, and are not within various exemptions that may be available under the CARD Act or under some of the various state or foreign jurisdictions, our liabilities with respect to unredeemed vouchers may be materially higher than the amounts shown in our financial statements and we may be subject to additional fines and penalties.
In addition, from time to time, we may be notified of additional laws, or developments in existing laws and regulations that governmental organizations or others may claim should be applicable to our business, or that otherwise affect our operations. If we are required to alter our business practices, or there are other market changes, as a result of any laws and regulations, our revenue could decrease, our costs could increase and our business could otherwise be harmed. In addition, the costs and expenses associated with defending any actions related to, or otherwise reacting to, such legal or regulatory developments, and any related payments (including penalties, judgments, settlements or fees) could adversely impact our profitability. To the extent that we expand into new lines of business and new geographies, we will become subject to additional laws and regulations.
If we are required to materially increase the liability recorded in our financial statements with respect to unredeemed vouchers our results of operations could be materially and adversely affected.
In certain states and foreign jurisdictions, vouchers may be considered a gift card. Some of these states and foreign jurisdictions include gift cards under their unclaimed and abandoned property laws which require

27




companies to remit to the government the full value or a portion of the value of the unredeemed balance on the gift cards after a specified period of time (generally between one and five years) and impose certain reporting and record-keeping obligations. We do not remit any amounts relating to unredeemed vouchers based on our assessment of applicable laws. The analysis of the potential application of the unclaimed and abandoned property laws to vouchers is complex, involving an analysis of constitutional and statutory provisions and factual issues, including our contractual relationship with customers and merchants. In recent periods, we increased our use of redemption payment terms with our North America merchants. The determinations we make with respect to variable consideration that we earn on those transactions may be subject to the laws described above. In the event that one or more states or foreign jurisdictions successfully challenges our position on the application of its unclaimed and abandoned property laws to vouchers, our liabilities with respect to unredeemed vouchers, including any resulting penalties and interest, may be materially higher than the amounts shown in our financial statements which could have a material adverse impact on our results of operations.
Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.
We are subject to general business regulations and laws as well as regulations and laws specifically governing the Internet and e-commerce, which could impede our growth or limit our ability to offer certain online services in the future. These regulations and laws may involve taxation, tariffs, subscriber privacy, anti-spam, data protection, content, reference pricing, copyrights, distribution, communications, consumer protection, the provision of online payment services and the characteristics and quality of services. The application of existing laws governing issues such as property ownership, sales and other taxes, libel and personal privacy to the Internet is not clear as the vast majority of these laws were adopted prior to the advent of, and do not contemplate or address the unique issues raised by, the Internet or e-commerce. In addition, it is possible that governments of one or more countries may seek to censor, or entirely block access to the content available on our websites, mobile applications, or marketing emails. Adverse legal or regulatory developments also could substantially harm our business. In particular, in the event that we are restricted, in whole or in part, from operating in one or more countries, our ability to retain or increase our customer base may be adversely affected and we may not be able to maintain or grow our gross profit as anticipated.
Failure to comply with existing, expanding or newly enacted U.S. federal, state and international privacy laws and regulations could adversely affect our business.
A variety of U.S. federal, state and international laws and regulations govern the collection, use, retention, sharing and security of consumer data. The existing privacy-related laws and regulations are evolving and subject to potentially differing interpretations. In addition, various U.S. federal, state and foreign legislative and regulatory bodies continue to enact new laws regarding privacy, as well as expand the scope of existing laws. For example, GDPR requires companies to satisfy requirements regarding the handling of personal and sensitive data, including its collection, use, security and the ability of persons whose data is stored to correct or delete such data about themselves. European countries continue to expand the scope of its application of GDPR within their local legislation. The California Consumer Privacy Act (the "CCPA") similarly regulates the collection and use of consumers' data, and the California Privacy Rights Act, (the "CPRA"), which expands on the CCPA, will go into effect in 2023, includes additional protection for sensitive personal data. The Virginia Consumer Data Protection Act (the "CDPA") and the Colorado Privacy Act (the "CPA"), which will also go into effect in 2023 provide new data privacy rights to their respective residents. Complying with the GDPR, CCPA, CPRA, CDPA, CPA and similar laws and regulations may cause us to incur substantial operational costs or require us to change our business practices. Further, despite our diligent efforts to comply with these laws and regulations, we may not be successful either due to internal or external factors such as resource allocation limitations or a lack of vendor cooperation. Noncompliance could result in proceedings against us by governmental entities or others and fines. For example, fines under GDPR could be up to the greater of €20 million or 4% of annual global revenue and damage our reputation and brand. As a result of GDPR, CCPA, CPRA and similar laws and regulations, we may experience difficulty retaining or obtaining new customers due to the compliance cost, potential risk exposure and portability of customer data. We also may find it necessary to establish and maintain systems and procedures to comply with these evolving laws and regulations that involve substantial expense and distraction from other aspects of our business. Additionally, there could be uncertainty around how to comply with privacy laws, in various jurisdictions such as country or state-specific laws that may conflict with or deviate from established privacy directives, or future laws and regulations in other jurisdictions.

28




We have posted privacy policies concerning the collection, use and disclosure of subscriber data as well as detailed cookie policies on our websites and applications. Several Internet companies have incurred substantial penalties for failing to abide by the representations made in their privacy policies and practices. In addition, several states in the U.S. have adopted legislation that requires businesses to implement and maintain reasonable security procedures and practices to protect sensitive personal information and to provide notice to consumers in the event of a security breach resulting in a loss or likely loss of personal information. Any failure, or perceived failure, by us to comply with our posted privacy policies or with any data-related consent orders, Federal Trade Commission requirements or orders or other U.S. federal, state or international privacy or consumer protection-related laws, regulations or industry self-regulatory principles could result in claims, proceedings or actions against us by governmental entities or other third-parties or other liabilities, which could adversely affect our business. In addition, a failure or perceived failure to comply with industry standards or with our own privacy policies and practices could result in a loss of subscribers or merchants and adversely affect our business. U.S. federal, state and international governmental authorities also continue to evaluate the privacy implications inherent in the use of web trackers, including the use of "cookies" for tracking and behavioral advertising. For example, member states in the European Union are working to align on a draft of the “ePrivacy Regulation,” which could be implemented in 2023, that would govern data privacy and the protection of personal data in electronic communications, in particular for direct marketing purposes. The regulation of web trackers and other current online advertising practices could adversely affect our business.
Misclassification or reclassification of our independent contractors or employees could increase our costs and adversely impact our business.
In the United States, our workers are classified as either employees or independent contractors, and if employees, as either exempt from overtime or non-exempt (and therefore overtime eligible). United States regulatory authorities and private parties have recently asserted within several industries that some independent contractors should be classified as employees and that some exempt employees, including those in sales-related positions, should be classified as non-exempt based upon the applicable facts and circumstances and their interpretations of existing rules and regulations. If we are found to have misclassified employees as independent contractors or non-exempt employees as exempt, we could face penalties and have additional exposure under federal and state tax, workers’ compensation, unemployment benefits, labor, employment and tort laws, including for prior periods, as well as potential liability for employee overtime and benefits and tax withholdings. Legislative, judicial, or regulatory (including tax) authorities could also introduce proposals or assert interpretations of existing rules and regulations that would change the classification of a significant number of independent contractors doing business with us from independent contractor to employee and a significant number of exempt employees to non-exempt. A reclassification in either case could result in a significant increase in employment-related costs such as wages, benefits and taxes as well as punitive damages in any related litigation. The costs associated with employee classification, including any related regulatory action or litigation, could have a material adverse effect on our results of operations and our financial position.
We may suffer liability as a result of information or content retrieved from or transmitted over the Internet and claims related to our service offerings.
We may be, and in certain cases have been, sued for defamation, civil rights infringement, negligence, patent, copyright or trademark infringement, invasion of privacy, personal injury, product liability, breach of contract, unfair competition, discrimination, antitrust reference pricing or other legal claims relating to information or content that is published or made available on our websites or service offerings we make available (including provision of an application programming interface platform for third parties to access our website, mobile device services and geolocation applications). This risk is enhanced in certain jurisdictions outside the United States, where our liability for such third-party actions may be less clear. In addition, we could incur significant costs in investigating and defending such claims, even if we ultimately are not found liable. If any of these events occurs, our business could be materially and adversely affected.
We are subject to risks associated with information disseminated through our websites and mobile applications, including consumer data, content that is produced by our editorial staff and errors or omissions related to the offerings on our marketplaces. Such information, whether accurate or inaccurate, may result in our being sued by our merchants, subscribers or third parties and as a result our results of operations and our financial position could be materially and adversely affected.

29




We may have exposure to greater than anticipated tax liabilities.
We are subject to income taxes in the United States (federal, state, and state)local) and numerous foreign jurisdictions. Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. Our income tax obligations are based on our corporate operating structure, including the manner in which we develop, value and use our intellectual property and the scope of our international operations.
The tax laws applicable to our domestic and international business activities, including the laws of the United States and other jurisdictions, are subject to interpretation. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for valuing developed technology or intercompany arrangements, which could potentially increase our worldwide effective tax rate and harm our financial position and results of operations. In addition, there are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be adversely affected by earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, losses incurred in jurisdictions for which we are not able to realize the related tax benefits, changes in foreign currency exchange rates, entry into new businesses and geographies and changes to our existing businesses, acquisitions and investments, changes in our deferred tax assets and liabilities and their valuation and changes in the relevant tax, accounting and other laws, regulations, administrative practices, principles and interpretations, including fundamental


21




changes to the tax laws applicable to corporate multinationals. DevelopmentsIn addition, we consider various factors that involve significant judgment by management, including projected future earnings, in determining whether we believe deferred tax assets will be realized and whether a valuation allowance should be recorded against such deferred tax assets. Our conclusions in these matters could prove to be incorrect, resulting in a reduction to deferred tax assets and lower income. Further, developments in an audit, litigation or the relevant laws, regulations, administrative practices, principles and interpretations could have a material effect on our financial position, operating results and cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods.
We also are subject to regular review and audit by both U.S. federal and state(federal, state. local) and foreign tax authorities. In particular, we currently are, and expect to continue to be, subject to numerous federal, state and international tax audits relating to income, transfer pricing, sales, VAT and other tax liabilities. Some of these pending and future audits could involve significant liabilities and/or penalties. We are subject to claims for tax assessments by foreign jurisdictions, including a proposed assessment for $113.3$118.5 million (inclusive of estimated incremental interest from the original assessment). We believe that the assessment, which primarily relates to transfer pricing on transactions occurring in 2011, is without merit and we intend to vigorously defend ourselves in that matter. See Item 8, Note 16,15, Income Taxes, for additional information. Any adverse outcome of such a review or audit could have a significant negative effect on our financial position and results of operations. In addition, the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment by management, and there are many transactions where the ultimate tax determination is uncertain. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made.
The adoption of tax reform policies, including the enactment of legislation or regulations implementing changes in the tax treatment of companies engaged in Internet commerce or theand U.S. taxation of international business activities could materially affect our financial position and results of operations.
Further, due to the global nature of the Internet, itIt is possible that various states or foreign countries might attempt tomay regulate our transmissions or levy additional sales, income or other taxes relating to our activities. Tax authorities at the international, federal, state and local levels are currently reviewing the appropriate treatment of companies engaged in Internet commerce and marketplace operators, and new or revised international, federal, state or local tax regulations may subject us or our customers to additional sales, income and other taxes. We cannot predict the effect of current attempts to impose sales, income or other taxes on commerce over the Internet. New or revised taxes and, in particular, obligations on online marketplaces and remote sellers to collect sales taxes, VAT and similar taxes, including digital service taxes, may result in liability for third party obligations and would likely increase the cost of doing business online and decrease the attractiveness of advertising and selling goods and services over the Internet. For example, the voucher directive adopted by the European Union, digital service taxes adopted by certain countries or similar regulations could adversely affect our financial results. New taxes or the

30




enactment of new tax laws could also create significant increases in internal costs necessary to capture data, and collect and remit taxes. Any of these events could have an adverse effect on our business and results of operations.
If weCurrently, there are required to materially increase the liability recorded in our financial statements with respect to unredeemed vouchers our results of operations could be materially and adversely affected.
In certain states and foreign jurisdictions, vouchers may be considered a gift card. Some of these states and foreign jurisdictions include gift cards under their unclaimed and abandoned property laws which require companies to remit to the government the full value or a portion of the value of the unredeemed balance on the gift cards after a specified period of time (generally between one and five years) and impose certain reporting and record-keeping obligations. We do not remit any amountsseveral pending U.S. legislative proposals relating to unredeemed vouchers based on our assessment of applicable laws. The analysis of the potential application of the unclaimedfederal tax laws and abandoned property laws to vouchers is complex, involving an analysis of constitutional and statutory provisions and factual issues, including our contractual relationship with customers and merchants. In recent periods, we increased our use of redemption payment terms with our North America merchants, and we expect that trend to continue. The determinations we make with respect to variable consideration that we earn on those transactions may be subject to the laws described above, and we expect the amount of that variable consideration to increase as our use of redemption payment terms increases. In the event that one or more states or foreign jurisdictions successfully challenges our position on the application of its unclaimed and abandoned property laws to vouchers, our liabilities with respect to unredeemed vouchers, including any resulting penalties and interest, may be materially higher than the amounts shown in our financial statements which could have a material adverse impact on our results of operations.

Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.
We are subject to general business regulations and laws as well as regulations and laws specifically governing the Internet and e-commerce. Existing and future regulations and laws could impede the growth of the Internet or other online services. These regulations and laws may involve taxation, tariffs, subscriber privacy, anti-spam, data protection, content, reference pricing, copyrights, distribution, electronic contracts and other communications, consumer protection, the provision of online payment services and the characteristics and quality of services. The application of existing laws governing issues such as property ownership, sales and other taxes, libel and personal privacy to the Internet is not clear as the vast majority of these laws were adopted prior to the advent and do not contemplate or address the unique issues raised by the Internet or e-commerce. In addition, it is possiblelikely that governments of one or more countries may seekthere will be further changes to censor content available on our websites and mobile applications or may even attempt to completely block our emails or access to our websites. Adverse legal or regulatory developments could substantially harm our business. In particular,U.S. federal tax law in the event that wefuture. The details of any proposed changes are restricted, in whole or in part, from operating in one or more countries, our abilitystill unknown. While these changes could impact Groupon's worldwide effective tax rate, it is difficult to retain or increase our customer base may be adversely affected and we may not be able to maintain or grow our gross profit as anticipated.
Failure to comply with federal, state and international privacy laws and regulations, or the expansion of current or the enactment of new privacy laws or regulations, could adversely affect our business.
A variety of federal, state and international laws and regulations govern the collection, use, retention, sharing and security of consumer data. The existing privacy-related laws and regulations are evolving and subject to potentially differing interpretations. In addition, various federal, state and foreign legislative and regulatory bodies may expand current or enact new laws regarding privacy matters. For example, the European Union adopted the GDPR, which became effective in May 2018, and requires companies to satisfy new requirements regarding the handling of personal and sensitive data, including its collection, use, protection and the ability of persons whose data is stored to correct or delete such data about themselves. In addition, the State of California adopted the California Consumer Protection Act of 2018 ("CCPA"), which became effective in January 2020, and also will regulate the collection and use of consumers' data. Complying with the GDPR, CCPA and similar laws and regulations may cause us to incur substantial operational costs or require us to change our business practices. Further, despite our diligent efforts to comply with these laws and regulations, we may not be successful either due to internal or external factors such as resource allocation limitations or a lack of vendor cooperation. Noncompliance could result in proceedings against us by governmental entities or others and fines. For example, fines under GDPR could be up to the greater of €20 million or 4% of annual global revenue and damage our reputation and brand. As a result of GDPR, in particular, we may also experience difficulty retaining or obtaining new European or multi-national customers due to the compliance cost, potential risk exposure, portability of customer data and uncertainty for these entities. We also may find it necessary to establish systems to maintain personal data originating from the European Union in the European Economic Area as a result of changes or restrictions to currently legitimate methods of effectuating cross-border personal data transfers to countries outside of the European Economic Area, which may involve substantial expense and distraction from other aspects of our business. Additionally, there could be uncertainty as to how to comply with privacy laws, in various jurisdictions such as country or state-specific laws that may conflict with or deviate from privacy directives, such as GDPR, CCPA or future laws and regulations.
We have posted privacy policies and practices concerning the collection, use and disclosure of subscriber data on our websites and applications. Several Internet companies have incurred substantial penalties for failing to abide by the representations made in their privacy policies and practices. In addition, several states have adopted legislation that requires businesses to implement and maintain reasonable security procedures and practices to protect sensitive personal information and to provide notice to consumers in the event of a security breach resulting in a loss or likely loss of personal information. Any failure, or perceived failure, by us to comply with our posted privacy policies or with any data-related consent orders, Federal Trade Commission requirements or orders or other federal, state or international privacy or consumer protection-related laws, regulations or industry self-regulatory principles could result in claims, proceedings or actions against us by governmental entities or other third-parties or other liabilities, which could adversely affect our business. In addition, a failure or perceived failure to comply with industry standards or with our own privacy policies and practices could result in a loss of subscribers or merchants and adversely affect our business. Federal, state and international governmental authorities continue to evaluate the privacy implications inherent in the use of third-party web "cookies" for tracking and behavioral advertising. The regulation of these cookies and other current online advertising practices could adversely affect our business.

Misclassification or reclassification of our independent contractors or employees could increase our costs and adversely impact our business.
Our workers are classified as either employees or independent contractors, and if employees, as either exempt from overtime or non-exempt (and therefore overtime eligible). Regulatory authorities and private parties have recently asserted within several industries that some independent contractors should be classified as employees and that some exempt employees, including those in sales-related positions, should be classified as non-exempt based upon the applicable facts and circumstances and their interpretations of existing rules and regulations. If we are found to have misclassified employees as independent contractors or non-exempt employees as exempt, we could face penalties and have additional exposure under federal and state tax, workers’ compensation, unemployment benefits, labor, employment and tort laws, including for prior periods, as well as potential liability for employee overtime and benefits and tax withholdings. Legislative, judicial, or regulatory (including tax) authorities could also introduce proposals or assert interpretations of existing rules and regulations that would change the classification of a significant number of independent contractors doing business with us from independent contractor to employee and a significant number of exempt employees to non-exempt. A reclassification in either case could result in a significant increase in employment-related costs such as wages, benefits and taxes. The costs associated with employee classification, including any related regulatory action or litigation, could have a material adverse effect on our results of operations and our financial position.
We may suffer liability as a result of information or content retrieved from or transmitted over the Internet and claims related to our service offerings.
We may be, and in certain cases have been, sued for defamation, civil rights infringement, negligence, patent, copyright or trademark infringement, invasion of privacy, personal injury, product liability, breach of contract, unfair competition, discrimination, antitrust reference pricing or other legal claims relating to information or content that is published or made available on our websites or service offerings we make available (including provision of an application programming interface platform for third parties to access our website, mobile device services and geolocation applications). This risk is enhanced in certain jurisdictions outside the United States, where our liability for such third-party actions may be less clear and we may be less protected. In addition, we could incur significant costs in investigating and defending such claims, even if we ultimately are not found liable. If any of these events occurs, our business could be materially and adversely affected.
We are subject to risks associated with information disseminated through our websites and mobile applications, including consumer data, content that is produced by our editorial staff and errors or omissions related to the offerings on our marketplaces. Such information, whether accurate or inaccurate, may result in our being sued by our merchants, subscribers or third parties and as a result our results of operations and our financial position could be materially and adversely affected.
As we increase our reliance on cloud-based platforms to operate and deliver our products and services, any disruption or interference with these platforms could adversely affect our financial condition and results of operations.
We are migrating a significant portion of our computing infrastructure to third party hosted cloud-based computing platforms. These migrations can be risky and may cause disruptions to the availability of our products due to service outages, downtime or other unforeseen issues that could increase our costs. We also may be subject to additional risk of cybersecurity breaches or other improper access to our data or confidential information during or following migrations to cloud-based computing platforms. In addition, cloud computing services may operate differently than anticipated when introduced or when new versions or enhancements are released. As we increase our reliance on cloud-based computing services, our exposure to damage from service interruptions may increase. In the event any such issues arise, it may be difficult for us to switch our operations from our primary cloud computing service providers to alternative providers. Further, any such transition would involve significant time and expense and could negatively impact our ability to deliver our products and services, which could harm our financial condition and results of operations.
We may not be able to adequately protect our intellectual property rights or may be accused of infringing intellectual property rights of third parties.
We regard our trademarks, service marks, copyrights, patents, trade dress, trade secrets, proprietary technology, merchant lists, subscriber lists, sales methodology and similar intellectual property as critical to our success,


24




and we rely on trademark, copyright and patent law, trade secret protection and confidentiality and/or license agreements with our employees and others to protect our proprietary rights. Effective intellectual property protection may not be available in every country in which our deals are made available. We also may not be able to acquire or maintain appropriate domain names or trademarks in all countries in which we do business. Furthermore, regulations governing domain names may not protect our trademarks and similar proprietary rights. We may be unable to prevent third parties from acquiring and using domain names or trade names that are similar to, infringe upon or diminish the value of our trademarks and other proprietary rights. We may be unable to prevent third parties from using and registering our trademarks, or trademarks that are similar to, or diminish the value of, our trademarks in some countries.
We may not be able to discover or determine the extent of any unauthorized use of our proprietary rights. Third parties that license our intellectual property rights also may take actions that diminish the value of our proprietary rights or reputation. The protection of our intellectual property may require the expenditure of significant financial and managerial resources. Moreover, the steps we take to protect our intellectual property may not adequately protect our rights or prevent third parties from infringing or misappropriating our proprietary rights. We are currently subject to multiple lawsuits and disputes related to our intellectual property and service offerings. We may in the future be subject to additional litigation and disputes. The costs of engaging in such litigation and disputes are considerable, and there can be no assurances that favorable outcomes will be obtained.
We are currently subject to third-party claims that we infringe upon proprietary rights or trademarks and expect to be subject to additional claims in the future. Such claims, whether or not meritorious, may result in the expenditure of significant financial and managerial resources, injunctions against us or the payment of damages by us. We may need to obtain licenses from third parties who allege that we have infringed their rights, but such licenses may not be available on terms acceptable to us or at all. These risks have been amplified by the increase in third parties whose sole or primary business is to assert such claims.
Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our ability to expand our base of customers and merchants could be impaired and our business and operating results could be harmed.
We believe that the brand identity that we have developed has significantly contributed to the success of our business. We also believe that maintaining and enhancing the "Groupon" brand is critical to expanding our base of customers and merchants. We intend to relaunch our brand in the second half of 2020 in an effort to evolve our image from deal-centric to a local experiences marketplace. In addition, maintaining and enhancing our brand may require us to make substantial additional investments over time and these investments may not be successful. If we fail to promote, maintain and protect the "Groupon" brand or if our brand relaunch is not successful, our business, operating results and financial condition may be adversely affected. We anticipate that, as the local experiences market becomes increasingly competitive, maintaining and enhancing our brand may become more difficult and expensive. Maintaining and enhancing our brand will depend largely on our ability to continue to provide reliable, trustworthy and high quality offerings on our marketplace, which we may not do successfully.
We receive a high degree of media coverage around the world. Unfavorable publicity or consumer perception of our websites, mobile applications, practices or service offerings, or the offerings of our merchants or their products, could adversely affect our reputation, resulting in difficulties in recruiting, decreased revenue and a negative impact on the number of merchants we feature and the size of our customer base, the loyalty of our customers and the number and variety of our offerings. As a result, our business, financial condition and results of operations could be materially and adversely affected.
Failure to deal effectively with fraudulent transactions and customer disputes would increase our loss rate and harm our business.
Groupon vouchers are issued in the form of redeemable vouchers with unique identifiers. It is possible that consumers or other third parties will seek to create counterfeit vouchers in order to fraudulently purchase discounted goods and services from merchants. While we use advanced anti-fraud technologies, criminals may attempt to circumvent our anti-fraud systems using increasingly sophisticated methods. In addition, our service could be subject to employee fraud or other internal security breaches, and we may be required to reimburse customers and/or merchants for any funds stolen or revenue lost as a result of such breaches. If merchants are affected by buyer fraud or other types of fraud, they could also request reimbursement, or stop offering goods or services on our marketplaces.


25




Although we have not incurred significant losses from fraud and counterfeit vouchers in the past, we could incur significant losses from such activities in future periods. Additionally, we may incur losses from claims that the customer did not authorize a purchase, from credit card fraud, from merchant fraud, from erroneous transmissions, and from customers who have closed bank accounts or have insufficient funds in them to satisfy payments. We also may incur losses as a result of purchases made with fraudulent credit card information, even if the associated financial institution approved paymentuntil further details of the transaction. In addition to the direct costs of any such losses, if the lossesproposed changes are related to credit card transactions and become excessive, they could potentially result in our losing the right to accept credit cards for payment. If we were unable to accept credit cards for payment, we would suffer substantial reductions in revenue, which would cause our business to suffer. While we have taken measures to detect and reduce the risk of fraud, these measures need continual improvement and may not be effective against new and continually evolving forms of fraud or in connection with new product offerings. If we are unable to effectively combat the use of fraudulent credit cards on our websites or if we otherwise experience increased levels of fraud or disputed credit card payments, our business could materially suffer.
We are subject to payments-related risks.
We accept payments using a variety of methods, including credit cards, debit cards and gift certificates. As we offer new payment options to customers, we may be subject to additional regulations, compliance requirements and fraud. For certain payment methods, including credit and debit cards, we pay interchange and other fees, which may increase over time and raise our operating costs and lower profitability. In addition, our credit card and other payment processors, at their discretion, could impose receivable holdback or reserve requirements in the future, which could have a material impact on our cash flow and available liquidity. As we implement our planned exit of the Goods category or in the event our strategy is unsuccessful, these payment processors could increase holdback amounts due to concerns with our financial condition, which could adversely affect our liquidity. We rely on third parties to provide payment processing services, including the processing of credit cards and debit cards, and it could disrupt our business if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from customers or facilitate other types of online payments, and our business and operating results could be adversely affected.
We are also subject to or voluntarily comply with a number of other laws and regulations relating to money laundering, international money transfers, privacy and information security and electronic fund transfers. If we were found to be in violation of applicable laws or regulations, we could be subject to civil and criminal penalties. In addition, events affecting our third-party payment processors or our integration with them, including cyber-attacks, Internet or other infrastructure or communications impairment or other events that could interrupt the normal operation of our payment processors or our integration with them, or result in unauthorized access to customer information, could have a material adverse effect on our business.issued.
Federal laws and regulations, such as the Bank Secrecy Act and the USA PATRIOT Act and similar foreign laws, could be expanded to include Groupon vouchers or other offerings.
Various federal laws, such as the Bank Secrecy Act and the USA PATRIOT Act and foreign laws and regulations, such as the European Directive on the prevention of the use of the financial system for the purpose of money laundering and terrorist financing, impose certain anti-money laundering requirements on companies that are financial institutions or that provide financial products and services. For these purposes, financial institutions are broadly defined to include money services businesses such as money transmitters, check cashers and sellers or issuers of stored value cards. Examples of anti-money laundering requirements imposed on financial institutions include subscriber identification and verification programs, record retention policies and procedures and transaction reporting. We do not believe that we are a financial institution subject to these laws and regulations based, in part, upon the characteristics of Groupon vouchers and our role with respect to the distribution of Groupon vouchers to customers. For example, the Financial Crimes Enforcement Network ("FinCEN"), a division of the U.S. Treasury Department tasked with implementing the requirements of the Bank Secrecy Act (the "BSA"), has adopted regulations expanding the scope of the BSA and requirements for parties involved in stored value or prepaid access cards, including a proposed expansion of financial institutions to include sellers or issuers of prepaid access cards. While we believe Groupon vouchers are not subject to these regulations, it is possible that FinCEN or a court of law could consider Groupon vouchers (or other Groupon products) a financial product and that we couldthus deem Groupon to be subject to such laws and obligations as a financial institution. In the event that we become subject to the requirements of the Bank Secrecy Act or any other anti-money laundering law or regulation imposing obligations on


26




us as a money services business, our regulatory compliance costs to meet these obligations would likely increase which could adversely impact our operating results.
State and foreign laws regulating money transmission could be expanded to include Groupon vouchers or other Groupon products or services.
Many states and certain foreign jurisdictions impose license and registration obligations on those companies engaged in the business of money transmission, with varying definitions of what constitutes money transmission. We currently believe that we are not a money transmitter given our role and the product terms of Groupon vouchers or other Groupon products or services. However, a successful challenge to our position or expansion of state or foreign laws could subject us to increased compliance costs and delay our ability to offer Groupon vouchers or other products or services in certain jurisdictions pending receipt of any necessary licenses or registrations.
Risks Related to Our Capital Structure
Our access to capital and ability to raise capital in the future may be limited, which could prevent us from growing, and our existing credit agreement could restrict our business activities.
We may need additional capital in the future and to seek additional financing. Suchfinancing or covenant relief. Any such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business. We have outstanding $230.0 million in aggregate principal amount of 1.125% convertible senior notes (the "2026 Notes") due March 2026. In addition, we are party to a $400.0$225.0 million amended and restated credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent,administrative agent, dated as of May 14, 2019, as amended by the First Amendment to the Second Amended and Restated Credit Agreement, dated as of July 17, 2020 and as further amended by the Second Amendment to the Second Amended and Restated Credit Agreement, dated as of March 22, 2021 (the "Credit"Amended Credit Agreement"), which matures in May 2024. Our
The Amended Credit Agreement contains financial and other covenants that may restrict our business activities or our ability to execute our strategic objectives,objectives. Due to the impact of COVID-19 on our business, we entered into amendments to the Amended Credit Agreement to provide, among other things, covenant relief through

31




the fourth quarter of 2021. We voluntarily elected to early terminate this covenant relief period as of the third quarter of 2021 and are again subject to the ordinary course covenants under the Amended Credit Agreement (beginning in the third quarter of 2021). In the future, these covenants could restrict our failureability to access the full capacity of our credit facility or require us to repay amounts borrowed. In addition, if we are not able to comply with these covenants, we may need to seek additional covenant relief in the future, which may be impacted by the duration and volatility of the recovery of our business from the ongoing COVID-19 pandemic. Failure to comply with the covenants contained in our Amended Credit Agreement (if not waived or further amended) could give rise to an event of default and, if not cured, entitle the lenders to accelerate the indebtedness outstanding thereunder and terminate our ability to borrow in the future under the Amended Credit Agreement. Further, acceleration of indebtedness under the Amended Credit Agreement could result in aan event of default under the indenture (the "Indenture") governing our 2026 Notes. Any termination of our ability to borrow or event of default under our Amended Credit Agreement. In addition,Agreement would have a material adverse impact on our liquidity.
Additionally, other general economic conditions as well asand our future operating performance, which we expect to be impacted by our planned exit of the Goods category, could ultimately limit our access to funding under our revolving credit agreement. We also expect a one-time decrease in working capital in 2020 in connection with our planned exit of the Goods category, which could impact our liquidity and, potentially, our access to capital during that period.Amended Credit Agreement. Furthermore, additional equity financing may dilute the interests of our common stockholders, and debt financing, if available, may involve restrictive covenants that could further restrict our business activities or our ability to execute our strategic objectives and could reduce our profitability. If we cannot access the full capacity of our credit facility or raise or borrow funds on acceptable terms or at all, it could adversely affect our liquidity, and we may not be able to grow our business or respond to competitive pressures.
In addition, advances under our revolving credit facility generally bear interest based on (i) the Alternate Base Rate (as defined in our Credit Agreement) or (ii) the Adjusted LIBO Rate (as defined in our Credit Agreement) and calculated using the London Inter-bank Offered Rate (“LIBOR”)). On July 27, 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021, and it is unclear whether new methods of calculating LIBOR will be established. If LIBOR ceases to exist after 2021, any calculation of interest based upon the Alternate Base Rate (or any comparable or replacement formulation), may result in higher interest rates. To the extent that these interest rates increase, our interest expense will increase, which could adversely affect our financial condition, operating results and cash flows.
We may not have the ability to useraise the funds necessary to settle conversions of the 2026 Notes in cash, to settlerepurchase the principal amount of our 3.25% convertible notes due 2022 (the "Notes") upon conversion or to repurchase the2026 Notes upon a fundamental change which could resultor to repay the 2026 Notes in dilution and could adversely affect our financial condition.
The Notes are convertible any time prior tocash at their maturity on April 1, 2022 into cash, stock(if not earlier converted, redeemed or a combination of cashrepurchased), and stock at an initial conversion rate set forth in the indenture governing the Notes (the "Indenture"). Notes that are converted in connection with a make-whole fundamental change (as defined in the Indenture) may be entitled to an increase in the conversation rate for such Notes. Upon a conversion event, if we do not have adequate cash available or cannot obtain additional financing, or our use of cash is restricted by applicable law, regulations or agreements governing our current orand future indebtedness, wedebt may not be ablecontain limitations on our ability to usepay cash to settle the principal amountupon conversions of the 2026 Notes upon conversion. If we settle any portionor at their maturity or to repurchase the 2026 Notes.
Holders of the principal amount of the2026 Notes upon conversion in stock, it will result in immediate dilution to the ownership interests of existing stockholders and such dilution could be material.
In addition, holders of the Notes have the right to require us to repurchase all or a portion of their 2026 Notes upon the occurrence of a fundamental change (as defined inbefore the Indenture)maturity date at a repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid interest, if any. IfIn addition, upon conversion of the 2026 Notes, unless we doelect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the 2026 Notes being converted. Moreover, we will be required to repay the 2026 Notes in cash at their maturity unless earlier converted, redeemed or repurchased. However, we may not have adequateenough available cash available or cannotbe able to obtain additional financing at the time we are required to make repurchases of the 2026 Notes surrendered therefor or pay cash with respect to the 2026 Notes being converted or at their maturity.
In addition, our useability to repurchase the 2026 Notes or to pay cash upon conversions of cash is restrictedthe 2026 Notes or at their maturity may be limited by applicable law, regulationsregulatory authority or agreements governing our current or future indebtedness, we may not be ableindebtedness.

An event ofA default under the Indenture governing the 2026 Notes could also lead to a default under other agreements governing our currentexisting and future indebtedness, and ifincluding our Amended Credit Agreement. Moreover, the repaymentoccurrence of a fundamental change under the Indenture governing the 2026 Notes could constitute an event of default under our Amended Credit Agreement or any other such otherfuture agreement. If the payment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay thesuch indebtedness and repurchase the 2026 Notes or makepay cash payments upon conversionwith respect to the 2026 Notes being converted or at maturity of the 2026 Notes.
The terms of the 2026 Notes could delay or prevent an attempt to take over our Company.
The terms of the 2026 Notes require us to repurchase the 2026 Notes in the event of a fundamental change. A takeover of our Company would constitute a fundamental change. This could have the effect of delaying or preventing a takeover of our Company that may otherwise be beneficial to our stockholders.

32




The conditional conversion feature of the 2026 Notes, if triggered, may adversely affect our financial condition and operating results.
In the event the conditional conversion feature of the 2026 Notes is triggered, holders of the 2026 Notes will be entitled to convert their 2026 Notes at any time during specified periods at their option. If one or more holders elect to convert their 2026 Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation in cash, which could adversely affect our liquidity. In addition, even if holders of the 2026 Notes do not elect to convert their 2026 Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2026 Notes, as a current rather than long-term liability, which would result in a material reduction of our net working capital.
Risks Related to Ownership of Our Common Stock
The trading price of our common stock is highly volatile.
The trading price of our common stock has fluctuated significantly since our initial listing on NASDAQ. We expect that the trading price of our stock will continue to be volatile due to variations in our operating results and also may change in response to other factors, including factors specific to technology and Internet commerce companies, many of which are beyond our control. Among the factors that could affect our stock price are:
our financial results;
any financial projections that we provide to the public, any changes in these projections or our failure for any reason to meet these projections or projections made by research analysts;
the number of shares of our common stock that are available for sale;
the relative success of competitive products or services;
the public's response to press releases or other public announcements by us or others, including our filings with the SEC and announcements relating to litigation;
the impact of COVID-19 on our business;
speculation about our business or investments in the press or the investment community;
future sales of our common stock by our significant stockholders, officers and directors;
announcements about ourany share repurchase program and purchases under the program;
changes in our capital structure, such as any refinancing or future issuances of debt or equity securities;
our entry into new markets or exits from existing markets;
regulatory developments;
strategic acquisitions, dispositions, partnerships, joint ventures, restructuring, financing or restructuringsother transactions announced or consummated by us or our competitors;
strategic dispositions of businessesfinancing or other assetstransactions announced or consummated by us;our minority investments;
our ability to execute our strategy;
our executive leadership transitions; and
changes in accounting principles.
We expect the stock price volatility to continue for the foreseeable future as a result of these and other factors.

33




If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research reports about our business, our share price and trading volume could decline.
The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts, and in the past, we have had changes in analyst ratings that have affected our stock price. If one or more of the analysts who cover us should downgrade our shares or change their opinion of our shares, industry sector or products, our share price would likely decline. If one or more of these analysts ceases coverage of our company or fails to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.


28




We do not intend to pay dividends for the foreseeable future.
We intend to retain all of our earnings for the foreseeable future to finance the operation and expansion of our business and do not anticipate paying cash dividends. As a result, stockholders can expect to receive a return on their investment in our common stock only if the market price of the stock increases.
Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable.
Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. These provisions include the following:
Our Board of Directors has the right to elect directors to fill a vacancy created by the expansion of the 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.
Special meetings of our stockholders may be called only by our Chairman of the Board of Directors, our Chief Executive Officer, our Board of Directors or holders of not less than the majority of our issued and outstanding common stock. This limits the ability of minority stockholders to take certain actions without an annual meeting of stockholders.
Our stockholders may not act by written consent unless the action to be effected and the taking of such action by written consent is approved in advance by our Board of Directors. As a result, a holder, or holders, controlling a majority of our common stock would generally not be able to take certain actions without holding a stockholders' meeting.
Our certificate of incorporation prohibits cumulative voting in the election of directors. This limits the ability of minority stockholders to elect director candidates.
Stockholders must provide timely notice to nominate individuals for election to the Board of Directors or to propose matters that can be acted upon at an annual meeting of stockholders. These provisions may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror's own slate of directors or otherwise attempting to obtain control of our company.
Our Board of Directors may issue, without stockholder approval, shares of undesignated preferred stock. The ability to authorize undesignated preferred stock 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.
The convertible note hedge and warrantcapped call transactions may affect the value of our 2026 Notes and our common stock.
On May 9, 2016, we purchased convertible note hedges from certain bank counterparties. The convertible note hedges are intended to reduceIn connection with the potential economic dilution upon conversionissuance of the Notes.

This activity could also cause or prevent an increase or decrease in the price of our common stock or the 2026 Notes, which could affect holders’ ability to convert the 2026 Notes, and, to the extent the activity occurs during any observation period related to a conversion of the 2026 Notes, or followingit could affect the amount and value of the consideration that holders will receive upon conversion of the 2026 Notes.

Any of the convertible note hedge and warrant transactions, including in connection with certain change of control transactions or other extraordinary events, the bank counterparties or their respective affiliates may unwind their hedge positions with respect to our common stock, whichthese activities could adversely affect the value of our common stock.
We are subject to counterparty risk with respect to the capped call transactions.
The counterparties to the capped call transactions are financial institutions, and we will be subject to the risk that one or more of the option counterparties may default, fail to perform or may exercise certain termination rights under the capped call transactions. Our exposure to the credit risk of the option counterparties will not be secured by any collateral.
Global economic conditions have in the past resulted in the actual or perceived failure of financial difficulties of many financial institutions. If a counterparty to the capped call transactions becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under such transactions. Our exposure will depend on many factors but, generally, our exposure will increase if the market price or the volatility of our common stock increases. In addition, upon a default or other failure to perform, or a termination of obligations by a counterparty, the counterparty may fail to deliver the shares of common stock required to be delivered to us under the capped call transactions and we may suffer adverse tax consequences or experience more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of the counterparties.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and related notes included under Item 8 of this Annual Report on Form 10-K. This discussion contains forward-looking statements about our business and operations. Our actual results may differ materially from those we currently anticipate as a result of many factors, including those we describe under Item 1A, Risk Factors, and elsewhere in this Annual Report. See Part I, Forward-Looking Statements, for additional information.
Overview
Groupon is a global scaled two-sided marketplace that connects consumers to merchants. Consumers access our marketplace through our mobile applications and our websites, primarily localized groupon.com sites in many countries.websites. We operate in two segments:segments, North America and International. For the year ended December 31, 2019, we derived 61.2% of our revenue from our North America segmentInternational, and 38.8% of our revenue from our International segment.in three categories, Local, Goods and Travel. See Item 8, Note 20,19, Segment Information, for additional information. Historically,
Currently, we have operated in three categories: Local, Goodsgenerate service and Travel. In February 2020, following a comprehensive review of opportunities and strategic alternatives, we announced that we plan to exit the Goods category by the end of 2020 and focus on our local experiences marketplace, which we believe best positions us for long-term and sustained growth.
We generate product and service revenue from our currentthe following business operations. We earn service
Service Revenue from Local, Travel, and Goods Categories: Service revenue from transactions in which we earnprimarily represents the net commissions byearned from selling goods or services on behalf of third-party merchants. Those transactions generally involve a customer's purchase of a voucher through one of our online marketplaces that can be redeemed with a third-party merchant for goods or services (or for discounts on goods or services). Service revenue from those transactions is reported on a net basis and equalsas the purchase price receivedcollected from the customer forless the voucher less an agreed upon portion of the purchase price paidthat is payable to the third-party merchant. Service revenueWe also includesearn commissions that we earn when customers make purchases with retailers using digital coupons accessed through our digital propertieswebsites and mobile applications.
Product Revenue from voucherless merchant offerings.Goods Category: We earngenerate product revenue from direct sales of our first-party Goods merchandise inventory through our Goods category. Ourinventory. For product revenue from those transactions, we are the primary party responsible for providing the merchandise to the customer, we have inventory risk and we have discretion in establishing prices. As such, product revenue is reported on a gross basis as the purchase price received from the customer. FollowingProduct revenue, including associated shipping revenue, is recognized when the merchandise is delivered to the customer. We fully transitioned to a third-party marketplace in North America in 2020 and in International in the fourth quarter of 2021. In a third-party marketplace model, our planned exitmerchants generally assume inventory and refund risk; therefore, we expect our Goods category to primarily generate revenue on a net basis within service revenue in future periods.
Strategy
Our mission is to be the destination for experiences where consumers discover fun things to do and local businesses thrive. Our strategic priorities are to expand our Local inventory and modernize our marketplace by improving the merchant and customer experiences.
To grow Local supply, we are focused on leveraging three types of inventory: deals with fewer restrictions, a lower discount inventory product called offers, and market rate supply. We began scaling elements of our inventory strategy throughout our marketplace in 2021. In North America, we scaled the removal of Deal repeat purchase restrictions to all merchants and as of December 31, 2021 over 80% of our Deal inventory is now repeatable. We have also successfully launched offers to beauty and wellness merchants.
To support our strategic priority of improving the merchant and customer experience, we are focused on reducing marketplace friction by making it easier for our customers to find, buy, and redeem a Groupon. To do this, we are exploring and launching new initiatives that we believe will improve engagement, conversion and customer purchase frequency over time. For merchants, we are continuing to focus on being a better partner by offering self-service options, advertising products and booking capabilities.
Moving forward, we plan to build an even better understanding of the Goods category, whichcritical value propositions we expectmust provide for our customers and merchants.
COVID-19, Restructuring and Cost Reduction
Since March 2020, the COVID-19 pandemic has led to occur bya significant disruption in our business due to changes in consumer behavior and impacts on our merchants. Recovery from the endCOVID-19 pandemic has been

and could continue to be volatile and prolonged given the unprecedented and continuously evolving nature of the situation and the emergence and spread of new variants. See Item 8, Note 3, COVID-19 Pandemic, for more information about the impacts of COVID-19 on our business.
In response to the impact of COVID-19 on our business, during the year ended December 31, 2020 we will no longer generate product revenue or service revenue from goods offerings. We currently anticipate that giventook significant actions to improve our plan to exitcash position and materially reduce our cost structure, including the Goods category, its financial results will ultimately be presented as a discontinued operation in our consolidated financial statements.Board approved multi-phase restructuring plan. See Item 8, Note 14, Restructuring and Related Charges, for more information.
How We Measure Our Business
We use several operating and financial metrics to assess the progress of our business and make decisions on where to allocate capital, time and technology investments. Certain of the financial metrics are reported in accordance with U.S. GAAP and certain of those metrics are considered non-GAAP financial measures. As our business evolves, we may make changes to the key financial and operating metrics that we use to measure our business. For further information and reconciliations to the most applicable financial measures under U.S. GAAP, refer to our discussion under Non-GAAP Financial Measures in the Results of Operations section.
Operating Metrics
Gross billings is the total dollar value of customer purchases of goods and services. Gross billings is presented net of customer refunds, order discounts and sales and related taxes. The substantial majority of our service revenue transactions are comprised of sales of vouchers and similar transactions in which we collect the transaction price from the customer and remit a portion of the transaction price to the third-party merchant who will provide the related goods or services. For these transactions, gross billings differs from revenue reported in our consolidated statements of operations, which is presented net of the merchant's share of the transaction price. For product revenue transactions, gross billings is equivalent to product revenue reported in our consolidated statements of operations. Gross billings is an indicator of our growth and business performance as it measures the dollar volume of transactions generated through our marketplaces. Tracking gross billings on service revenue transactions also allows us to monitor the percentage of gross billings that we are able to retain after payments to merchants. However, we are focused on achieving long-term gross profit and Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA") growth.
Units are the number of purchases during the reporting period, before refunds and cancellations, made either through one of our online marketplaces or directly with a merchant for which we earn a commission. We do not include purchases with retailers using digital coupons accessed through our websites or mobile applications in our units metric, nor do we include units purchased through third-party marketplaces with which we partner. We consider units to be an important indicator of the total volume of business conducted through our marketplaces. We report units on a gross basis prior to the consideration of customer refunds and therefore units are not always a good proxy for gross billings.
Active customers are unique user accounts that have made a purchase during the trailing twelve months ("TTM") either through one of our online marketplaces or directly with a merchant for which we earned a commission. We consider this metric to be an important indicator of our business performance as it helps us to understand how the number of customers actively purchasing our offerings is trending. Some customers could establish and make purchases from more than one account, so it is possible that our active customer metric may count certain customers more than once in a given period. We do not include consumers who solely make purchases with retailers using digital coupons accessed through our websites or mobile applications in our active customer metric, nor do we include consumers who solely make purchases of our inventory through third-party marketplaces with which we partner. is the total dollar value of customer purchases of goods and services.

We consider this metric to be an important indicator of our business performance as it helps us to understand how the number of customers actively purchasing our offerings is trending. Some customers could establish and make purchases from more than one account, so it is possible that our active customer metric may count certain customers more than once in a given period. For entities that we have acquired in a business combination, this metric includes active customers of the acquired entity, including customers who made purchases prior to the acquisition. We do not include consumers who solely make purchases with retailers using digital coupons accessed through our websites and mobile applications in our active customer metric, nor do we include consumers who solely make purchases of our inventory through third-party marketplaces with which we partner.
Gross billings and gross profit per active customer are the TTM gross billings and gross profit generated per active customer. We use these metrics to evaluate trends in customer spend and in the average contribution to gross billings and gross profit on a per-customer basis.

Financial Metrics
Revenue is currently earned through product and service revenue transactions. We earn service revenue from transactions in which we generate commissions by selling goods or services on behalf of third-party merchants. Service revenue is reported on a net basis as the purchase price collected from the customer less the portion of the purchase price that is payable to the third-party merchant. Service revenue also includes commissions we earn when customers make purchases with retailers using digital coupons accessed through our digital properties. We generate product revenue from our sales of first-party Goods merchandise inventory. Our product revenue from these first-party transactions, which are direct sales of merchandise inventory, is the purchase price received from the customer. We fully transitioned to a third-party marketplace in North America in 2020 and in International in the fourth quarter of 2021. In a third-party marketplace model, our merchants generally assume inventory and refund risk; therefore, we expect our Goods category to primarily generate revenue on a net basis within service revenue in future periods.
is earned through product and service revenue transactions. We earn service revenue from transactions in which we generate commissions by selling goods or services on behalf of third-party merchants, primarily through sales of vouchers and similar transactions in which we collect the transaction price from the customer and remit a portion of that transaction price to the third-party merchant who will provide the related goods or services. We report service revenue from those transactions on a net basis as the purchase price collected from the customer less the portion of the purchase price that is payable to the third-party merchant. Service revenue also includes commissions we earn when customers make purchases with retailers using digital coupons accessed through our websites and mobile applications. We earn product revenue from direct sales of merchandise inventory in our Goods category and report product revenue on a gross basis as the purchase price received from the customer. After we exit the Goods category, we will no longer generate product revenue or service revenue from goods offerings.
Gross profit reflects the net margin we earn after deducting our cost of revenue from our revenue. Due to the lack of comparability between product revenue, which is reported on a gross basis, and service revenue, which is reported on a gross basis, and service revenue, which

primarily consists of transactions reported on a net basis, we believe that gross profit is an important measure for evaluating our performance.
Adjusted EBITDA is a non-GAAP financial measure that we define as net income (loss) from continuing operations excluding income taxes, interest and other non-operating items, depreciation and amortization, stock-based compensation, acquisition-related expense (benefit), net and other special charges and credits, including items that are unusual in nature or infrequently occurring. For further information and a reconciliation to Income (loss) from continuing operations, refer to our discussion under Non-GAAP Financial Measures in the Results of Operations section.

Operating Expenses
Marketing expense consists primarily of online marketing costs, such as search engine marketing, advertising on social networking sites and affiliate programs, and to a lesser extent offline marketing costs, such as television and radio advertising. Additionally, compensation expense for marketing employees is classified within marketing expense. We record these costs within Marketing on the consolidated statements of operations when incurred. From time to time, we have offerings from well-known national merchants for customer acquisition and activation purposes, for which the amount we owe the merchant for

each voucher sold exceeds the transaction price paid by the customer. Our gross billings from those transactions generate no service revenue and our net cost (i.e., the excess of the amount owed to the merchant over the amount paid by the customer) is classified as marketing expense. We evaluate marketing expense as a percentage of gross profit because it gives us an indication of how well our marketing spend is driving gross profit performance.
Selling, general and administrative ("SG&A") expenses include selling expenses such as sales commissions and other compensation expenses for sales representatives, as well as costs associated with supporting the sales function such as technology, telecommunications and travel. General and administrative expenses include compensation expense for employees involved in customer service, operations, technology and product development, as well as general corporate functions, such as finance, legal and human resources. Additional costs included in general and administrative include depreciation and amortization, rent, professional fees, litigation costs, travel and entertainment, recruiting, office supplies, maintenance, certain technology costs and other general corporate costs. We evaluate SG&A expense as a percentage of gross profit because it gives us an indication of our operating efficiency.
Restructuring and related charges represent severance and benefit costs for workforce reductions, impairments and other facilities-related costs and professional advisory fees. See Item 8, Note 14, Restructuring and Related Charges, for information about our restructuring plan.

Factors Affecting Our Performance
Impact of COVID-19.During the COVID-19 pandemic, protective measures taken to control the spread of COVID-19 and changes in consumer behavior have had and continue to have a negative impact on our business, which relies on customers' purchases of local experiences, including events and activities, beauty and wellness, travel and dining. Recovery from the COVID-19 pandemic has been and could continue to be volatile and prolonged given the unprecedented and continuously-evolving nature of the situation and the emergence and spread of variants. We also have been, and may continue to be, impacted by pandemic-related supply chain issues, staffing shortages and other transient issues that affect our merchants and continue to evolve during the pandemic recovery period.
We will continue to monitor the impact of COVID-19 on our business, particularly in our International segment where restrictions to date have been more prolonged and stricter than in North America.
Attracting and retaining local merchants.As we seek to build a more completefocus on our local experiences marketplace, we depend on our ability to attract and retain merchants who are willing to offer their experiences on our platform. Merchants can generally withdraw their offerings from our marketplace at any time, and their willingness to continue offering services through our marketplace depends on the effectiveness of our marketing and promotional services. We are focused on prioritizing opportunities to help drive demand for our merchants by highlighting offers that customers want and that they can enjoy right now in light of any ongoing COVID-related restrictions. As we navigate through the volatility of the COVID-19 recovery period, we intend to take a market-by-market approach to attracting and retaining local merchants.

Driving purchase frequency and re-engaging and retaining customers. customersIn. As the global economy continues to recover from the pandemic, we are surfacing relevant inventory in order to drive purchase frequency and retain our customers, we must increase high-quality inventory density in core cities,customers. We also continue to improvefocus on expanding inventory through our three inventory products: deals with fewer restrictions, a lower discount inventory product called offers, and market rate supply. On the customer experience onside, we continue to improve our websites and mobile applications, andapplications; launch innovative products that remove friction from the customer journey.journey and drive awareness to our supply; and grow our high-quality, repeatable inventory.

Increasing traffic to our websites and mobile applications. The traffic to our websites and mobile applications, including from consumers responding to our emails and search engine optimization ("SEO"), has declined in recent years. As such, we must focus on developing sources of traffic in addition to email and SEO and optimizing the efficiency of our marketing spending, which is primarily guided by return on investment thresholds that are based on expected months-to-payback targets ranging from 12 to 18 months. We also plan to relaunch our brand in 2020, and our new marketing strategy will take a full-funnel approach to drive top-of-mind awareness.
In addition to the factors outlined above, we believe that our plan to exit the Goods category by the end of 2020 presents three key challenges set forth below that could affect our performance:
Disruption caused by the planned Goods exit. Aligning our global organization toward one vision may cause disruption that negatively impacts our team. We must encourage our employees to focus on our core priorities and work to minimize disruption including decreased productivity, employee morale and retention.
Consultation and negotiation with international workers’ councils. We must inform, negotiate and consult with our international workers’ councils on an exit plan for our Goods category, which may impact the timing, cost and execution of our planned exit in International.
Keeping our cross-shopping customers engaged on our platform. As we shift more impressions toward our Local category, we intend to target our Goods-Local cross-shoppers with marketing efforts designed to retain these customers.

Comparison of the Years Ended December 31, 20192021 and 2018:2020:
North America gross billings, units and TTM active customers declineddecreased by 4.1$12.3 million, 13.7 million and 2.7 million for the year ended December 31, 2019. The decline is2021 compared with the prior year. These declines were primarily attributable to a decline in traffic, including traffic from email and SEO, as well as our efforts to improve the efficiency of our marketing spend, which has led to a decrease in the number of active customers. We expect the trend of declining active customers inconsumer demand for our North America segment to continue in 2020 due to ongoing traffic declines and our plan to exit the Goods category, by the end of 2020.
The decline in active customers also impacted North America gross billings and units, which declined by $437.1 million and 19.3 million for the year ended December 31, 2019.The decrease in gross billings was partially offset by higher gross billings per unit due to a shiftan increase in mix ofconsumer demand for higher-priced offerings sold.and lower customer refunds in the Local category.

our ongoing focus on optimizing for long-term gross profit generation rather than gross billings growth, which resulted in merchandising and product mix decisions that adversely impacted transaction volume and gross billings from our Goods category;
ceasing most of our food delivery operations in the third quarter 2017, which resulted in a $45.9 million decrease in Local gross billings; and
a $25.5 million unfavorable impact on gross billings for the year ended December 31, 2018 as a result of adopting Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("Topic 606") as compared with previous accounting guidance.

Comparison of the Years Ended December 31, 20192021 and 2018:2020:
International revenue and cost of revenue decreased by $238.2 million and $238.0 million for the year ended December 31, 2021 compared with the prior year. Those decreases were primarily due to lower Local and Goods gross billings and the transition of Goods to a third-party marketplace model. In a third-party marketplace model, we generate service revenue which is presented on a net basis. These declines were partially offset by higher variable consideration from unredeemed vouchers. Revenue had a favorable impact of $19.0 million and cost of revenue had an unfavorable impact of $11.5 million from year-over-year changes in foreign currency exchange rates.
International gross profit remained largely flat for the year ended December 31, 2021 compared with the prior year. International gross profit increased primarily due to higher variable consideration from unredeemed vouchers and a favorable impact of $7.4 million from year-over-year changes in foreign currency exchange rates.

Our U.S. Federal income tax rate was 21% for the years ended December 31, 20192021, 2020 and 2018 and 35%2019.
The primary factors impacting the effective tax rate for the year ended December 31, 2017. 2021 were the release of a portion of the U.S. valuation allowance against our federal and state deferred tax assets, pretax losses incurred in jurisdictions that have a valuation allowance against their net deferred tax assets, and the non-taxable unrealized gain on the observable price change recorded on an other equity investment.
The primary factor impacting the effective tax rate for the years ended December 31, 2020 and 2019 2018 and 2017 was thewere impacted by pretax losses incurred in jurisdictions that have a valuation allowancesallowance against their net deferred tax assets.assets and the reversal of reserves for uncertain tax positions due to the closure of applicable statutes of limitations and closure of tax audits. The year ended December 31, 2020 was also impacted by the carryback of federal net operating losses due to the income tax relief provided by the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). The year ended December 31, 2019 was also impacted by the non-taxable unrealized gain on the observable price change recorded on an other equity investment. We expect that our consolidated effective tax rate in future periods will continue to differ significantly from the U.S. federal income tax rate as a result of our tax obligations in jurisdictions with profits and valuation allowances in jurisdictions with losses.
See Item 8, Note 16,15, Income Taxes, for additional information relating to tax audits and assessments and regulatory and legal developments that may impact our business and results of operations in the future.future.
The effective tax rate for the year ended December 31, 2019 also reflected the reversal of reserves for uncertain tax positions due to the closure of a tax audit and due to the close of applicable statutes of limitation. The effective tax rate for year ended December 31, 2018 also reflected a $6.4 million income tax benefit resulting from the impact of adopting Topic 606 on intercompany activity in certain foreign jurisdictions.
Income (Loss) from Discontinued Operations
In connection with a strategic initiative to optimize our global footprint, we sold or ceased our operations in 12 countries between November 2016 and March 2017. The financial results of those operations have been presented as discontinued operations in the consolidated financial statements. See Item 8, Note 3, Discontinued Operations, for additional information about the dispositions and see Item 8, Note 11, Commitments and Contingencies, for information about indemnification obligations related to discontinued operations.
Non-GAAP Financial Measures
In addition to financial results reported in accordance with U.S. GAAP, we have provided the following non-GAAP financial measures: Adjusted EBITDA, free cash flow and foreign currency exchange rate neutral operating results. Those non-GAAP financial measures, which are presented on a continuing operations basis, are intended to aid investors in better understanding our current financial performance and prospects for the future as seen through the eyes of management. We believe that those non-GAAP financial measures facilitate comparisons with our historical results and with the results of peer companies who present similar measures (although other companies may define non-GAAP measures differently than we define them, even when similar terms are used to identify such measures). However, those non-GAAP financial measures are not intended to be a substitute for those reported in accordance with U.S. GAAP.
Adjusted EBITDA. Adjusted EBITDA is a non-GAAP performance measure that we define as net incomeIncome (loss) from continuing operations excluding income taxes, interest and other non-operating items, depreciation and amortization, stock-based compensation, acquisition-related expense (benefit), net and other special charges and credits, including items that are unusual in nature or infrequently occurring. Our definition of Adjusted EBITDA may differ from similar measures used by other companies, even when similar terms are used to identify such measures. Adjusted EBITDA is a key measure used by our management and Board of Directors to evaluate operating performance, generate future operating plans and make strategic decisions for the allocation of capital. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and Board of Directors. However, Adjusted EBITDA is not intended to be a substitute for incomeIncome (loss) from continuing operations.

We exclude stock-based compensation expense and depreciation and amortization because they are primarily non-cash in nature and we believe that non-GAAP financial measures excluding those items provide meaningful supplemental information about our operating performance and liquidity. Acquisition-related expense (benefit), net is comprised of the change in the fair value of contingent consideration arrangements and external transaction costs related to business combinations, primarily consisting of legal and advisory fees. The composition of our contingent consideration arrangements and the impact of those arrangements on our operating results vary over time based on a number of factors, including the terms of our business combinations and the timing of those transactions. For the yearsyear ended December 31, 2019, 2018, 2017,2021, special charges and credits included charges related to our restructuring plan.plan and long-lived asset impairments. For the year ended December 31, 2018,2020, special charges and credits also included a $34.6 million chargecharges related to our patent litigation with IBM. For the year ended December 31, 2017, special chargesrestructuring plan, goodwill and credits also included a $17.1 million credit related to the sale of intangible assets (see Item 8, Note 6, Goodwilllong-lived asset impairments and Other Intangible Assets).strategic advisor costs. We exclude special charges and credits from Adjusted EBITDA because we believe that excluding those items provides meaningful supplemental information about our core operating performance and facilitates comparisons with our historical results.
The following is a reconciliation of Adjusted EBITDA to the most comparable U.S. GAAP financial measure, Income (loss) from continuing operations for the years ended December 31, 2019, 2018,2021, 2020, and 20172019 (dollars in thousands):

Refer to Item 8, Note 14, Restructuring and Related Charges and Note 6, Investments, for additional information.
Free cash flow. Free cash flow is a non-GAAP liquidity measure that comprises net cash provided by operating activities from continuing operations less purchases of property and equipment and capitalized software. We use free cash flow to conduct and evaluate our business because, although it is similar to cash flow from continuing operations, we believe that it typically represents a more useful measure of cash flows because purchases of fixed assets, software developed for internal use and website development costs are necessary components of our ongoing operations. Free cash flow is not intended to represent the total increase or decrease in our cash balance for the applicable period.
Free cash flow has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures. For example, free cash flow does not include cash payments for business acquisitions. In addition, free cash flow reflects the impact of the timing difference between when we are paid by customers and when we pay merchants and suppliers. Therefore, we believe it is important to view free cash flow as a complement to our entire consolidated statements of cash flows. For a reconciliation of free cash flow to the most comparable U.S. GAAP financial measure, see Liquidity and Capital Resources below.

Our revenue-generating transactions are primarily structured such that we collect cash up-front from customers and pay third-party merchants at a later date, either based on a fixed payment schedule or upon the customer's redemption of the related voucher. For merchants onvoucher or fixed payment terms, we remit payments on an ongoing basis,which are generally bi-weekly,biweekly, throughout the term of the merchant's offering. For purchases of merchandise inventory, our supplier payment terms generally range from net 30 to net 60 days. WeHistorically, we have primarily paid merchants on fixed payment terms in North America and upon voucher redemption internationally. In prior periods, we beganWe largely completed a transition to increase our use of redemption payment terms with ourin North America merchants and we expect that trend to continue.in the third quarter 2020.

Our cash balances fluctuate significantly throughout the year based on many variables, including gross billings growth rates, the timing of payments to merchants and suppliers seasonality and the mix of transactions between Goods and Local.
Net cash provided by (used in) operating activities
For example, we have historically generated strongthe year ended December 31, 2021, our net cash inflows duringused in operating activities from continuing operations was $124.0 million, as compared with our $120.3 million income from continuing operations. That difference was primarily attributable to a $197.7 million net decrease from changes in working capital and other non-current assets and liabilities. The working capital impact was largely related to a shortening of the fourth quarter holidaycustomer purchase to redemption cycle relative to year-end 2020 when redemption patterns were more heavily impacted by COVID-19, resulting in higher merchant payment outflows for the year. The difference between our net cash used in operating activities and our net income from continuing operations is also due to $46.6 million of non-cash items, including $95.6 million of changes in fair value of our investments, $50.7 million of changes in our valuation allowance and a $32.3 million foreign currency translation adjustment gain that was reclassified into earnings as a result of the substantial liquidation of our subsidiary in Japan, partially offset by depreciation and amortization and stock-based compensation.

For the year ended December 31, 2020, our net cash used in operating activities from continuing operations was $63.6 million, as compared with our $286.6 million loss from continuing operations. That difference was primarily attributable to $295.6 million of non-cash items, including $109.5 million of goodwill impairment, $22.4 million of long-lived asset impairments, $21.6 million of restructuring-related impairments, depreciation and amortization and stock-based compensation, partially offset by a $72.6 million net decrease from changes in working capital and other assets and liabilities. The working capital decrease was due to the impacts of COVID-19, partially offset by the transition to a third-party goods marketplace in North America.

For the year ended December 31, 2019, our net cash provided by operating activities from continuing operations was $71.3 million, as compared with our $14.3 million loss from continuing operations. That difference was primarily attributable to $230.6$230.2 million of non-cash items, including depreciation and amortization, stock-based compensation, a $69.4 million loss from changes in fair value of our investment in Monster LP and a $51.4 million upward adjustment to an otheranother equity investment for observable price changes in an orderly transaction. The difference between our net cash provided by operating activities and our income from continuing operations due to non-cash items was partially offset by a $145.0 million net decrease from changes in working capital and other assets and liabilities. The working capital impact was primarily related to the decline of billings, and to a lesser extent seasonal timing of payments to inventory suppliers.
For the year ended December 31, 2018, our netNet cash provided by operating(used in) investing activities from continuing operations was $190.9 million, as compared with our $2.0 million income from continuing operations.

The difference between our net cash provided by operating activities and our income from continuing operations due to non-cash items was partially offset by a $17.9 million net decrease from changes in working capital and other assets and liabilities. The working capital impact was primarily related to the seasonal timing of payments to inventory suppliers and also includes $42.1 million of the payment to IBM related to the settlement of our patent litigation.
For the year ended December 31, 2017,2021, our net cash provided by operating activities from continuing operations was $130.5 million, as compared with our $28.6 million income from continuing operations. That difference was primarily attributable to $209.1 million of non-cash items, including depreciation and amortization, stock-based compensation and the gain on sale of intangible assets. The difference between net cash provided by operating activities and our income from continuing operations due to non-cash items was partially offset by a $107.1 million decrease from changes in working capital and other assets and liabilities. The working capital impact was primarily related to the seasonal timing of payments to inventory suppliers and payments related to our restructuring activities.

We were in compliance with the applicable covenants as of December 31, 2021. In the future, these covenants could restrict our ability to access the full capacity of our credit facility or require us to repay amounts borrowed. In addition, if we are not able to comply with these covenants, we may need to seek additional covenant relief in the future.
In March and April 2021, we also issued convertible senior notes due 2026 (the "2026 Notes") and used a portion of the net proceeds from the 2026 Notes to purchase the capped call transactions and, together with cash on hand, we repurchased the Atairos Notes in May 2021. See Item 1, Risk Factors and Item 8, Note 9,8, Financing Arrangements, for additional information.
We believe that our cash balances, excluding borrowings under the Amended Credit Agreement, and cash generated from operations will be sufficient to meet our working capital requirements and capital expenditures for at least the next 12 months. We plan to continue to actively manage and optimize our cash balances and liquidity, working capital and operating expenses, although there can be no assurances that we will be able to do so.
As of December 31, 2019,2021, we had $205.2$66.6 million in cash held by our international subsidiaries, which is primarily denominated in Euros, British Pounds Sterling, Canadian dollars, and, to a lesser extent, Australian dollars

and Japanese yen.dollars. In general, it is our practice and intention to re-invest the earnings of our non-U.S. subsidiaries in those operations. We have not, nor do we anticipate the need to, repatriate funds to the United States to satisfy domestic liquidity needs arising in the ordinary course of business.
In May 2018, the Board of Directors authorized us to repurchase up to $300.0 million of our common stock under our share repurchase program. During the year ended December 31, 2019, we repurchased 14,027,227 shares for an aggregate purchase price of $45.2 million (including fees and commissions) under our repurchase program. As of December 31, 2019,2021, up to $245.0 million of common stock remained available for purchase under our program. The timing and amount of share repurchases, if any, will be determined based on market conditions, limitations under the 2019Amended Credit Agreement, share price, available cash and other factors, and the share repurchase program may be terminated at any time. Repurchases will be made in compliance with SEC rules and other legal requirements and may be made, in part, under a Rule 10b5-1 plan, which permits share repurchases when we might otherwise be precluded from doing so.
In April 2016, we issued convertible notes with an aggregate principal amount of $250.0 million. We received net proceeds of $243.2 million from the issuance of the Notes. We have used the proceeds from the Notes for general corporate purposes, including repurchases of shares of our common stock. Additionally, we entered into note hedge and warrant transactions with certain bank counterparties that are designed to offset, in part, the potential dilution from conversion of the Notes. See Item 8, Note 9, Financing Arrangements, for additional information.
Our cash balances and cash flows generated from our operations may be used to fund strategic investments, business acquisitions, working capital needs, investments in technology, marketing and share repurchases. Additionally, we have the ability to borrow funds under the 2019 Credit Agreement, which requires compliance with specified financial covenants. Although we were in compliance with all covenants as of December 31, 2019, general economic conditions, as well as our future operating performance, which will be impacted by our plan to exit the Goods category by the end of 2020, could limit our access to funding under our revolving credit agreement. We could also seek to raise additional financing, if available on terms that we believe are favorable, to increase the amount of liquid funds that we can access for acquisitions, share repurchases or other strategic investment opportunities. We also believe our working capital will be impacted by our plan to exit the Goods category, and expect a one-time decrease in working capital, which could impact our liquidity. Although we can provide no assurances, we believe that our cash balances and cash generated from operations should be sufficient to meet our working capital requirements and capital expenditures for at least the next twelve months.

Critical Accounting Policies and Estimates
Management's Discussion and Analysis of Financial Condition and Results of Operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Our significant accounting policies are discussed in Item 8, Note 2, Summary of Significant Accounting Policies, in the notes to the consolidated financial statements.
The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities, revenue and expenses, and related disclosure of contingent liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from those estimates under different assumptions or conditions.
We believe that the estimates and assumptions related to revenue recognition, lease recognition, impairment assessments, of goodwill and long-lived assets, income taxes and fair value option investments have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.
Revenue Recognition
We make significant estimates related to revenue recognition including estimates for refund reserve, variable consideration from vouchers that will not ultimately be redeemed, and breakage income from customer credits that are not expected to be used. We estimate future refunds, voucher redemptions, and customer credit redemptions using historical refund and redemption experience. We also consider trends, such as changes to our policies or in general economic conditions that may impact customer behavior, when making those estimates. We reevaluate our estimate as facts and circumstances change.
These estimates rely on judgments regarding future expectations of customer behavior. While the basis of our estimates is historical data, customer behavior may not always be predictable. If actual refunds or redemptions differ from our estimates, the effects could be material to the consolidated financial statements.
Refer toSee Item 8, Note 2, Summary of Significant Accounting Policies and Item 8, Note 14,13, Revenue Recognition, for information about our revenue recognition accounting policies, including estimates of our refund liabilities.
Leases
Refer to Item 8, Note 2, Summary of Significant Accounting Policies and Item 8, Note 10, Leases for information about our lease accounting policies, including lease recognition policy.policies.
Impairment Assessments of Goodwill and Long-Lived Assets
Refer to Item 8, Note 2, Summary of Significant Accounting Policies, and Note 6, Goodwill and Other Intangible Assets, for information about our accounting policies relatingImpairment assessment estimates applies to goodwill, long-lived assets, right-of-use assets and investments.
Goodwill is allocated to our reporting units at the date the goodwill is initially recorded. We evaluate goodwill for impairment annually on October 1 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. We review our long-lived assets, such as property, equipment and software, intangible assets, right-of-use assets and investments for impairment whenever events or changes in circumstances indicate that the carrying amount of long-lived assets. Additional information about those accounting policiesan asset or asset group may not be recoverable. Significant judgment and estimates is set forth inare required when determining the following paragraphs.fair value of these assets for impairment tests.
When determining fair values in impairment tests, we use one of the following recognized valuation methods: the income approach (including discounted cash flows), the market approach andor the cost approach. Our significant estimates in those fair value measurements may include identifying business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and earnings multiples. Further, when measuring fair value based on discounted cash flows, we make assumptions about risk-adjusted discount rates; rates of increase in revenue, cost of revenue and operating expenses; weighted average cost of capital; rates of long-term growth; and income tax rates. Valuations are performed by management or third-party valuation specialists under management's supervision, where appropriate. We believe that the estimated fair values used in impairment tests are based on reasonable assumptions that marketplace participants would use. However, such assumptions are inherently uncertain and actual results could differ from those estimates. See Item 8, Note 4, Property, Equipment and Software, Net, Note 5, Goodwill and Other Intangible Assets, Note 6, Investments and Note 9, Leases for more information about our impairment assessments.
Our three reporting units as of October 1, 2019 were North America, EMEA (Europe, the Middle East and Africa) and Asia Pacific. There was no impairment of goodwill for any reporting unit because the fair values of the reporting units exceeded their carrying values.

56




Future changes in our assumptions or the interrelationship of the assumptions described above may negatively impact future valuations. In future measurements of fair value, adverse changes in assumptions could result in impairments of goodwill or long-lived assets that would require non-cash charges to the consolidated statements of operations and may have a material effect on our financial condition and operating results.
See Item 8, Note 2, Summary of Significant Accounting Policies for information about our accounting policies relating to impairment of goodwill and long-lived assets.
Income Taxes
We account for income taxes using the asset and liability method and assess whether it is more likely than not that the deferred tax assets will be realized. We are also subject to taxation in the United States, various states and foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording the related income tax assets and liabilities.
To assess whether it is more likely than not that deferred tax assets will be realized and whether a valuation allowance needs to be recorded against them, we consider the following four sources of taxable income for each tax jurisdiction: (a) future reversals of existing taxable temporary differences, (b) projected future earnings, (c) taxable income in carryback years, and (d) tax planning strategies.
During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. For example, our effective tax rate could be adversely affected by earnings being lower than anticipated in countries where it has lower statutory rates and higher than anticipated in countries where it has higher statutory rates, by changes in foreign currency exchange rates, by changes in the valuation of deferred tax assets and liabilities, by changes in the measurement of uncertain tax positions, by changes affecting transfer pricing or by changes in the relevant laws, regulations, principles and interpretations.
Refer toSee Item 8, Note 2, Summary of Significant Accounting Policies, and Note 16,15, Income Taxes, for information about our income tax accounting policies.

Fair Value Option Investments

value. Estimating the fair values of our investments requires significant judgment regarding of the assumptions that market participants would use in pricing those assets.
As the fair value measurements involve significant unobservable inputs, such as cash flow projections and discount rates, they are classified as Level 3 within the fair value hierarchy. Future changes in judgment about the related fair value inputs, including changes that may result from any subsequent financing transactions undertaken by those investees, could result in significant increases or decreases in fair value that would be recognized in earnings. Our election to apply fair value accounting to those investments has and may continue to cause fluctuations in our earnings from period to period.
See Item 8, Note 6, Investments, for information about the fair value measurements of our fair value option investments.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our business, including the effect of foreign currency fluctuations, interest rate changes and inflation. Information relating to quantitative and qualitative disclosures about these market risks is set forth below.
Foreign Currency Exchange Risk
We transact business in various foreign currencies other than the U.S. dollar, principally the euro, British pound sterling, Canadian dollar and Australian dollar, which exposes us to foreign currency risk. For the year ended December 31, 2019,2021, we derived approximately 38.8%37.2% of our revenue from our International segment. Revenue and related expenses generated from our international operations are generally denominated in the local currencies of the corresponding countries. The functional currencies of our subsidiaries that either operate or support these markets are generally the same as the corresponding local currencies. However, the results of operations of, and certain of our intercompany balances associated with, our international operations are exposed to foreign currency exchange rate fluctuations. Upon consolidation, as exchange rates vary, our revenue and other operating results may differ materially from expectations, and we may record significant gains or losses on the re-measurement of intercompany balances.
We assess our foreign currency exchange risk based on hypothetical changes in rates utilizing a sensitivity analysis that measures the potential impact on working capital based on a 10% change (increase and decrease) in currency rates. We use a current market pricing model to assess the changes in the value of the U.S. dollar on foreign currency denominated monetary assets and liabilities. The primary assumption used in this model is a hypothetical 10% weakening or strengthening of the U.S. dollar against those currency exposures as of December 31, 20192021 and 2018.2020.
As of December 31, 2019,2021, our net working capital deficit (defined as current assets less current liabilities) from subsidiaries that are subject to foreign currency translation risk was $69.2 million. The potential increase in this working capital deficit from a hypothetical 10% adverse change in quoted foreign currency exchange rates would be $6.9 million. This compares to a $20.8with an $11.4 million working capital deficitsurplus subject to foreign currency exposure as of December 31, 2018,2020, for which a 10% adverse change would have resulted in a potential increase in this working capital deficitsurplus of $2.1$1.1 million.
Interest Rate Risk
Our cash balance as of December 31, 20192021 consists of bank deposits and government money market funds, so exposure to market risk for changes in interest rates is limited. In March and April 2016,2021, we issued convertible notesthe 2026 Notes with an aggregate principal amount of $250.0$230.0 million (see Item 8, Note 9,8, Financing Arrangements). The convertible notes2026 Notes bear interest at a fixed rate, so we have no financial statement impact from changes in interest rates. However, changes in market interest rates impact the fair value of the convertible notes2026 Notes along with other variables such as our credit spreads and the market price and volatility of our common stock. In May 2019, we entered into the 2019Our Amended Credit Agreement which provides for aggregate principal borrowings of up to $400.0$225.0 million. As of December 31, 2019,2021, we had no$100.0 million of borrowings outstanding and $25.8 million of outstanding letters of credit under the 2019Amended Credit Agreement. See Item 7, Liquidity and Capital Resources, for additional information. Because borrowings under the 2019Amended Credit Agreement bearsbear interest at a variable rate, we are exposed to market risk relating to changes in interest rates if we borrow under the 2019Amended Credit Agreement. We also have $156.9$91.4 million of lease obligations as of December 31, 2019.2021. Interest rates on existing leases typically do not change unless there is a modification to a lease agreement and as such, we do not believe that the interest rate risk on the lease obligations is significant.
Impact of Inflation
We believe that ourOur results of operations arehave not been materially impacted by moderate changes in the inflation rate. Inflation and changing prices did not have a material effect on our business, financial condition or results of operations for the year ended December 31, 2019.

Adoption of New Lease Accounting Standard
As discussed in Note 10 to the financial statements, the Company has changed its method of accounting for leases in 2019 due to the adoption of the guidance in ASC Topic 842, Leases, using the modified retrospective method.
Adoption of New Revenue Recognition Accounting Standard
As discussed in Note 14 to the financial statements, the Company has changed its method of accounting for revenue transactions in 2018 due to the adoption of the guidance in ASC Topic 606, Revenue from Contracts with Customers, using the modified retrospective method.
Basis for Opinion
These financial statements are the responsibility of the Company'sCompany’s management. Our responsibility is to express an opinion on the Company'sCompany’s financial statements based on our audits. 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 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 financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Income Taxes - Foreign tax position- Variable Consideration Revenue Recognition—Refer to Notes 2 and 1613 to the financial statements
Critical Audit Matter Description
In accordance with the measurement principles of the revenue recognition accounting standard, the Company estimates variable consideration and includes such estimates in its determination of the transaction price that is recognized as revenue. The Company’s estimate of variable consideration each period is associated with gross billings for vouchers that are ultimately not redeemed by customers and for which the Company’s payment terms to merchants are upon redemption. For vouchers with redemption payment terms, the merchant is not paid its share of the sale price for a voucher sold unless and until the customer redeems the related voucher. If the voucher is never redeemed by the customer, the Company retains the full amount paid for the voucher and is not required to remit to the merchant its portion of the voucher’s sales proceeds.
Evaluating management’s model and assumptions used to estimate variable consideration revenue involved especially subjective judgment.

60




How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to evaluating the Company’s model and assumptions used to estimate the variable consideration revenue amount included the following, among others:
We tested the effectiveness of controls over the estimation of the variable consideration revenue.
We evaluated the Company’s model used to measure the variable consideration revenue amount by considering if it conforms with the objectives and measurement principles of the revenue recognition standard related to variable consideration.
We evaluated whether the Company used the proper data in the model. We also tested the completeness and accuracy of the data used in the model.
We evaluated the assumptions used in the model, specifically the estimated redemption rates for cohorts of vouchers, by comparing the assumed redemption rates used in the model to historical redemption rates for similar vouchers.
Valuation Allowance on Deferred Tax Assets—Refer to Notes 2 and Note 15 to the financial statements
Critical Audit Matter Description
The Company recognizes deferred income tax assets and liabilities for the estimated future tax effects attributable to temporary differences and carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized in the future. Future realization of deferred tax assets depends on the existence of sufficient taxable income within the carryback or carryforward period of the appropriate character under the relevant tax law. Sources of taxable income include future reversals of deferred tax assets and liabilities, future taxable income (exclusive of the reversals of deferred tax assets and liabilities), taxable income in prior carryback year(s) if permitted under the tax law, and tax planning strategies. During 2021, the Company reversed $57.7 million of its valuation allowance related to domestic deferred tax assets because they concluded that it was more-likely-than-not that the domestic deferred tax assets were realizable based on current circumstances. The Company’s valuation allowance for all deferred tax assets was $145.1 million as of December 31, 2021.
The Company’s determination of the valuation allowance involves estimates. Management’s primary estimate in determining whether a valuation allowance should be established is the projection of future sources of taxable income. Auditing management’s estimate of future sources of taxable income, which affects the recorded valuation allowances, involved especially subjective judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to evaluating the basis for management’s conclusions regarding the realizability of deferred tax assets included the following, among others:
We tested the effectiveness of controls over management’s deferred tax asset realizability assessment.
With the assistance of our income tax specialists, we considered relevant tax laws and regulations in evaluating the appropriateness of management’s estimates of future sources of taxable income.
We evaluated the reasonableness of management’s estimates of future sources of taxable income by comparing the estimates to historical sources of taxable income or losses and to forecasted information used in other areas of management’s accounting reporting models. We also evaluated management’s ability to reliably forecast by comparing actual results to management’s historical forecasts.
With the assistance of our income tax specialists, we evaluated whether the estimated future sources of taxable income were of the appropriate character to utilize the deferred tax assets under tax law.
We evaluated management’s assessment that it is more-likely-than-not that sufficient taxable income will be generated in the future to utilize the net domestic deferred tax assets. We considered the appropriateness of the timing of the change in assessment of realizability of the domestic deferred tax assets, giving consideration to current and historical facts and circumstances.
Income Taxes—Foreign Tax Position—Refer to Notes 2 and 15 to the financial statements
Critical Audit Matter Description

believes the assessment, which primarily relates to transfer pricing on transactions occurring during 2011, is without merit and it intends to vigorously defend itself.
Given the complexity of the relevant tax laws and regulations, auditing management’s evaluation and accounting for the tax position associated with the foreign income tax assessment involved especially subjective and complex judgments.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the accounting for the tax position associated with the foreign income tax assessment included the following, among others:
We tested the effectiveness of controls over income taxes, including those over accounting for uncertain tax positions.
With the assistance of our foreign and US income tax specialists, we evaluated management’s analysis regarding the likelihood of sustaining its foreign tax position upon examination by the relevant foreign tax authorities; and, we evaluated management’s estimate of the amount of tax benefit recognized.
We assessed the basis of the Company’s analysis and measurement by:
Obtaining, reading, and evaluating the outside legal opinion received by the Company supporting its foreign tax position
Obtaining, reading, and evaluating the written response from the outside legal counsel representing the Company provided to us as part of our annual legal inquiry process

Evaluating any developments in the matter during the current fiscal year through inquiry of Company personnel and their outside legal counsel.
Investments - Monster Holdings LP Fair Value Option Investment - Refer to Notes 2 and 7 to the financial statements
Critical Audit Matter Description
The Company has a minority interest investment in Monster Holdings LP, an entity based in the Republic of Korea, which is accounted for using the fair value method. When determining the fair value of the investment, management is required to make significant estimates and assumptions, particularly regarding cash flow forecasts of the investee, including revenue growth, margins, and operating expenses. The Company recorded a $69.4 million loss during 2019 due to a decline in the fair value of the investment. The reported fair value of the investment at December 31, 2019 is $0.
Auditing the Company’s cash flow forecasts of the investee used in its valuation of its investment in Monster Holdings LP involved especially subjective judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the forecasted cash flows of the investee included the following, among others:
We tested the effectiveness of controls over the measurement of the fair value of the investment, including those over the determination of forecasted cash flows of the investee.
We assessed the reasonableness of forecasted investee cash flows by (1) comparing the projections to historical results and previous forecasts, (2) considering the extent of management’s historical ability to reliably forecast prospective operating results of the investee, (3) obtaining and evaluating management’s written analysis supporting the forecasted cash flows of the investee, and (4) makingaccounting position

primarily using the income approach (including discounted cash flows) and the market approach.. With respect to the income approach, management makes significant estimates and assumptions related to forecasts of future performance, including revenues; earnings before interest, income taxes, depreciation,revenues, cost of revenue, and amortization (EBITDA) margins;operating expenses and risk-adjusted discount rates. The goodwill balance subject to the impairment test was $325$216.4 million as of December 31, 2019. 2021. The Company did not record any goodwill impairment charges for the year ended December 31, 2021.
Auditing the estimates and assumptions that impacted the valuation of the reporting units involved especially subjective judgment, specifically related to the forecasts of revenues, EBITDA margins,cost of revenue, and operating expenses and selection of risk-adjusted discount rates.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the Company’s forecasts of revenues, cost of revenue, and EBITDA margins,operating expenses and its selection of risk-adjusted discount rates included the following, among others:
We tested the effectiveness of controls over the annual and periodic goodwill impairment assessment, including those over the forecasts.
We evaluated management’s ability to accuratelyreliably forecast by comparing actual results to management’s historical forecasts.

The consolidated financial statements were prepared in accordance with U.S. GAAP and include the assets, liabilities, revenue and expenses of all wholly-owned subsidiaries and majority-owned subsidiaries over which we exercise control and variable interest entities for which we have determined that we are the primary beneficiary. Outside stockholders' interests in subsidiaries are shown on the consolidated financial statements as Noncontrolling interests. Investments in entities in which we do not have a controlling financial interest are accounted for at fair value, as available-for-sale securities or at cost adjusted for observable price changes and impairments, as appropriate.
Adoption of New Accounting Standards
We adopted the guidance in ASU 2016-02,Accounting Standards Update ("ASU") 2019-12, Leases(Topic 842), on January 1, 2019. This ASU requiresIncome Taxes (Topic 740) - Simplifying the recognition of lease assets and liabilitiesAccounting for operating leases, in addition to the finance lease assets and liabilities historically recorded on our consolidated balance sheets. See Note 10, Leases, for additional information on the impact of adopting Topic 842 on our accounting policies.
We adopted the guidance in ASU 2018-07, Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting,Income Taxes, on January 1, 2019.2021. This ASU expandssimplifies the scopeaccounting for income taxes by removing certain exceptions to make the general principles in Topic 740 and also clarifies and amends existing guidance for share-based payment awards to nonemployeesimprove consistent with the guidance for share-based payment awards to employees.application. The adoption of ASU 2018-072019-12 did not have a material impact on the consolidated financial statements.
We adopted the guidance in ASU 2018-15,2020-03, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,Codification Improvements to Financial Instruments, on January 1, 2019.2021.

The requirements of ASU 2018-15 have been applied on a prospective basis to implementation costs incurred on or after January 1, 2019. As a result of the adoption of ASU 2018-15, we capitalized $7.4 million of implementation costs for the year ended December 31, 2019.

We adopted the guidance in ASC Topic 606, Revenue from Contracts with Customers, on January 1, 2018. Topic 606 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. We adopted Topic 606 using the modified retrospective method. Beginning on January 1, 2018, results are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. The adoption of Topic 606 did not significantly impact our presentation of revenue on a gross or net basis. For additional information on the impact of adoption of Topic 606 on our accounting policies, refer to our discussion under Revenue Recognition below.
We recorded a net reduction to our opening accumulated deficit of $88.9 million, which is net of a $6.7 million income tax effect, as of January 1, 2018 due to the cumulative impact of adopting Topic 606. The following table summarizes balance sheet accounts impacted by the cumulative effect of adopting Topic 606 (in thousands):
  Increase (decrease) to beginning accumulated deficit
Prepaid expenses and other current assets $(4,007)
Other non-current assets (10,223)
Accrued merchant and supplier payables (64,970)
Accrued expenses and other current liabilities (13,188)
Other non-current liabilities 3,443
Effect on beginning accumulated deficit $(88,945)
We adopted the guidance in ASU 2016-01, Financial Instruments (Topic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities, as amended, on January 1, 2018. This ASU generally requires equity investments to be measured at fair value with changes in fair value recognized through net income and eliminates the cost method for equity securities. However, for equity investments without readily determinable fair values, the ASU permits entities to elect to measure the investments at cost adjusted for observable price changes and impairments, with changes in the measurement recognized through net income. We applied that measurement alternative to our equity investments that were previously accounted for under the cost method. At the time of the adoption of ASU 2016-01, there was not a material impact on the consolidated financial statements.
We adopted the guidance in ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash, on January 1, 2018. This ASU requires companies to include amounts generally described as restricted cash and restricted cash equivalents, along with cash and cash equivalents, when reconciling the beginning-of-period and end-of-period amounts shown on the statement of cash flows. Previously, changes in restricted cash were reported within cash flows from operating activities. We applied that change in cash flow classification on a retrospective basis, which resulted in a $7.0 million decrease to net cash provided by operating activities for the year ended December 31, 2017.
We adopted the guidance in ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, on January 1, 2018. This ASU is meant to clarify the scope of ASC Subtopic 610-20, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets, and to add guidance for partial sales of nonfinancial assets.leases. The adoption of ASU 2017-052020-03 did not have a material impact on the consolidated financial statements.
We early adopted the guidance in ASU 2017-07,2020-06, CompensationDebt - Retirement Benefits (Topic 715)Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Improving the Presentation of Net Periodic Pension CostContracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Net Periodic Postretirement Benefit CostContracts in an Entity's Own Equity, , on January 1, 2018. This2021. The ASU requires employersremoves the separation models for convertible debt with a cash conversion feature or convertible instruments with a beneficial conversion feature. Additionally, the ASU removes certain conditions for equity classification related to include onlycontracts in an entity’s own equity (e.g., warrants) and amends certain guidance related to the service cost componentcomputation of net periodic pension costincome (loss) per share for convertible instruments and contracts in operating expenses, together with other employee compensation costs. The other components of net periodic pension cost, including interest cost, expected return on plan assets, amortization of prior service cost and settlement and curtailment effects, arean entity’s own equity.    
Prior to be included in non-operating expenses. Thethe adoption of ASU 2017-07 did not have a material impact on2020-06, we separated the consolidated financial statements.
We adoptedconvertible senior notes due 2022 (the "Atairos Notes") into their liability and equity components. Following the guidance in ASU 2017-09, Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting, on January 1, 2018. This ASU clarifies the changes to terms or conditions of a share-based payment award that require an entity to apply modification accounting. The adoption of ASU 2017-09 did2020-06, the previously bifurcated equity component of the Atairos Notes was recombined with the liability component, resulting in a single liability-classified instrument. The carrying value of the Atairos Notes at transition was determined by recalculating the basis of the Atairos Notes as if the conversion option had not have a material impact onbeen bifurcated at issuance.

Together with the cash interest, this resulted in an effective interest rate of January 1, 2018. This ASU permits a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the "Jobs Act")3.76%. As a result of adopting ASU 2020-06 in the adoptionfirst quarter of ASU 2018-02,2021, we reclassified $0.2 million from accumulated other comprehensive income to accumulated deficit.
We adopted the guidance in ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of a Business, on July 1, 2017. This ASU provides clarification on the definition of a business and provides guidance on whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance in ASU 2017-01 was applied in determining that the sale of customer lists and other intangible assets in certain food delivery markets, as described in Note 6, Goodwill and Other Intangible Assets, did not meet the definition of a business. The adoption of ASU 2017-01 did not otherwise have a material impact on the consolidated financial statements.
We adopted the guidance in ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory (Topic 740), on January 1, 2017. This ASU requires immediate recognition of the income tax consequences of intercompany asset transfers other than inventory. We recorded a $3.2$67.0 million cumulative effect adjustmentnet reduction to additional paid-in capital, a $19.0 million increase to Convertible senior notes, net and a $48.0 million reduction to our opening accumulated deficit as of January 1, 20172021. In the fourth quarter of 2021, we recorded an additional $2.7 million adjustment to recognize the impactour opening accumulated deficit and additional paid-in capital related to tax impacts of that change in accounting policy.
We adopted the guidance in ASU 2015-11, Inventory (Topic 330) - Simplifying the Measurement of Inventory, on January 1, 2017. This ASU requires inventory to be measured at the lower of cost or net realizable value, rather than the lower of cost or market. The adoption of ASU 2015-11 did not have a material impact on the consolidated financial statements.our bond hedges.
Reclassifications
Certain reclassifications have been made to the consolidated financial statements of prior periods and the accompanying notes to conform to the current period presentation, including the change in presentation of restricted cash in the consolidated statements of cash flows upon adoption of ASU 2016-18 as described above.presentation.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAPgenerally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities, revenue and expenses, and the related disclosures of contingent liabilitiesreported in the consolidated financial statements and accompanying notes. Estimates in our financial statements include, but are used for, but not limited to, the following: variable consideration from unredeemed vouchers,vouchers; income taxes, leases,taxes; leases; initial valuation and subsequent impairment testing of goodwill, andother intangible assets investments,and long-lived assets; investments; receivables; customer refunds and other reserves; contingent liabilitiesliabilities; and the useful lives of property, equipment and software and intangible assets. Actual results could differ materially from those estimates.
Cash, Cash Equivalents and Restricted Cash
We consider all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Restricted cash represents amounts that we are unable to access for operational purposes. These amounts primarily relate to withholdings from employee paychecks under our employee stock purchase plan ("ESPP").
Accounts Receivable, Net
Accounts receivable primarily represents the net cash due from credit card and other payment processors and from merchants and performance marketing networks for commissions earned on consumer purchases. The carrying amount of receivables is reduced by an allowance for doubtful accountsexpected credit losses that reflects management's best estimate of amounts that will not be collected. TheWe establish an allowance isfor expected credit losses on accounts receivable based on identifying the following customer risk characteristics: size, type of customer, and payment terms offered in the normal course of business. Receivables with similar risk characteristics are grouped into pools. For each pool, we consider the historical credit loss experience, current economic conditions, bankruptcy filings, published or estimated credit default rates, age of the receivable and any specific risks identifiedrecoveries in collection matters. Accounts receivable are charged off againstassessing the allowance for doubtful accounts when it is determined that the receivable is uncollectible.

Inventories
 Inventories, consisting of merchandise purchased for resale, are accounted for using the first-in, first-out method of accounting and are valued at the lower of cost or net realizable value. We write down our inventory to the lower of cost or net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected, additional inventory write-downs may be required. Once established, the original cost of the inventory less the related inventory write-down represents a new cost basis.lifetime expected credit losses.
Property and Equipment
Property and equipment are stated at cost and assets under finance leases are stated at the lesser of the present value of minimum lease payments or their fair market value.cost. Depreciation and amortization of property and equipment is recorded on a straight-line basis over the estimated useful lives of the assets. Generally, the useful lives are three to five years for computer hardware, and office equipment, five to ten years for furniture and fixtures and warehouse equipment and the shorter of the term of the lease or five yearsthe expected life of the underlying asset for leasehold improvements and assets under finance leases.improvements.
Internal-Use Software
We incur costs related to internal-use software and website development, including purchased software and internally-developed software. Costs incurred in the planning and evaluation stage of internally-developed software and website development are expensed as incurred. Costs incurred and accumulated during the application development stage are capitalized and included within Property, equipment and software, net on the consolidated balance sheets. Amortization of internal-use software is recorded on a straight-line basis over the two-year estimated useful life of the assets.

Cloud Computing Costs
We have entered into non-cancellablenon-cancelable cloud computing hosting arrangements for which we incur implementation costs. Costs incurred in the planning and evaluation stage of the cloud computing hosting arrangement are expensed as incurred. Costs incurred during the application development stage related to implementation of the hosting arrangement are capitalized and included within Prepaid expenses and other current assets and Other non-current assets on the consolidated balance sheets. Amortization of implementation costs is recorded on a straight-line basis over the term of the associated hosting arrangement for each module or component of the related hosting arrangement when it is ready for its intended use. Amortization costs will beare recorded primarily in Selling, general and administrative expense on the consolidated statements of operations.
Impairment of Long-Lived Assets
Long-lived assets, such as property, equipment and software and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If circumstances require that a long-lived asset or asset group to be held and used be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that long-lived asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value.
Long-lived assets or disposal groups classified as held for sale are recorded at the lower of their carrying amount or fair value less estimated selling costs. Long-lived assets are not depreciated or amortized while classified as held for sale.
Goodwill
Goodwill is allocated to our reporting units at the date the goodwill is initially recorded.acquisition. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill.

We evaluate goodwill for impairment annually on October 1 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. We have the option to assess goodwill for impairment by first performing a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount.value. If we determine that it is more-likely-than-notdetermined that the reporting unit fair value of a reporting unit is more-likely-than-not less than its carrying amount,value, or if we do not elect the option to perform an initial qualitative assessment, we perform the two-step goodwill impairment test.

If the fair value of the reporting unit is in excess of its bookcarrying value, the related goodwill is not impaired and no further analysis is necessary.impaired. If the fair value of the reporting unit is less than its bookthe carrying value, there iswe recognize an indication of potential impairment and a second step is performed. When required,equal to the second step of testing involves calculating the implied fair value of goodwill for the reporting unit. The implied fair value of goodwill is determined in the same manner as goodwill recognized in a business combination, which is the excess of the fair value of the reporting unit determined in step one over the fair value of its net assets, including identifiable intangible assets, as if the reporting unit had been acquired. Ifdifference between the carrying value of the reporting unit's goodwill exceeds the impliedunit and its fair value, not to exceed the carrying value of that goodwill, an impairment loss is recognized in an amount equal to that excess. For reporting units with a negative book value (i.e., excess of liabilities over assets), we evaluate qualitative factors to determine whether it is necessary to perform the second step of the goodwill impairment test.
During the fourth quarter of 2019, we determined the deterioration of our financial condition when compared with our previous projections to be a triggering event requiring assessment of goodwill impairment as of December 31, 2019. There was no goodwill impairment recognized for the year ended December 31, 2019 as a result of that assessment.goodwill.
Investments
Investments in equity shares without a readily determinable fair value and for which we do not have the ability to exercise significant influence are accounted for at cost adjusted for observable price changes and impairments, with changes in the measurement recognized through net income (loss). Those investments are classified within Investments on the consolidated balance sheets.
We have investments in common stock or in-substance common stock for which we have the ability to exercise significant influence and we have made an irrevocable election to account for those investments at fair value. Those investments are classified within Investments on the consolidated balance sheets.
Investments in convertibleWe classify our debt securities and convertible redeemable preferred shares are accounted for as available-for-sale securities, which are classified within Investments on the consolidated balance sheets. Available-for-sale securities are recorded at fair value each reporting period. Unrealized gains and losses, net of the related tax effects, are excluded from earnings and recorded as a separate component within Accumulated other comprehensive income (loss) on the consolidated balance sheets until realized. Interest income from available-for-sale securities is reported within Other income (expense), net on the consolidated statements of operations.
Other-than-Temporary Impairment of Investments
An unrealized loss exists when the current fair value of an investment is less than its cost basis. We conduct reviews of our available-for-sale investments with unrealized losses on a quarterly basis to evaluate whether those impairments are other-than-temporary. This evaluation, which is performed at the individual investment level, considers qualitative and quantitative factors regarding the severity and duration of the unrealized loss, as well as our intent and ability to hold the investment for a period of time that is sufficient to allow for an anticipated recovery in value. Evidence considered in this evaluation includes the amount of the impairment, the length of time that the investment has been impaired, the factors contributing to the impairment, the financial condition and near-term prospects of the investee, recent operating trends and forecasted performance of the investee, market conditions in the geographic area or industry in which the investee operates and our strategic plans for holding the investment in relation to the period of time expected for an anticipated recovery in value. Additionally, we consider whether we intend to sell the investment or whether it is more likely than not that it will be required to sell the investment before recovery of its amortized cost basis. Investments with unrealized losses that are determined to be other-than-temporary are written down to fair value with a charge to earnings. Unrealized losses that are determined to be temporary in nature are recorded, net of tax, in Accumulated other comprehensive income (loss) for available-for-sale securities.

Income Taxes
We account for income taxes using the asset and liability method, under which deferred income tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. We regularly review deferred tax assets to assess whether it is more likely than not that the deferred tax assets will be realized and, if necessary, establish a valuation allowance for portions of such assets to reduce the carrying value.

72


GROUPON, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
For purposes of assessing whether it is more likely than not that deferred tax assets will be realized, we consider the following four sources of taxable income for each tax jurisdiction: (a) future reversals of existing taxable temporary differences, (b) projected future earnings, (c) taxable income in carryback years, to the extent that carrybacks are permitted under the tax laws of the applicable jurisdiction, and (d) tax planning strategies, which represent prudent and feasible actions that a company ordinarily might not take, but would take to prevent an operating loss or tax credit carryforward from expiring unused. To the extent that evidence about one or more of these sources of taxable income is sufficient to support a conclusion that a valuation allowance is not necessary, other sources need not be considered. Otherwise, evidence about each of the sources of taxable income is considered in arriving at a conclusion about the need for and amount of a valuation allowance. See Note 16, Income Taxes, for further information about our valuation allowance assessments.
We are subject to taxation in the United States, various states and foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording the related income tax assets and liabilities. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. For example, our effective tax rate could be adversely affected by earnings being lower than anticipated in countries where it has lower statutory rates and higher than anticipated in countries where it has higher statutory rates, by changes in foreign currency exchange rates, by changes in the valuation of deferred tax assets and liabilities, by changes in the measurement of uncertain tax positions or by changes in the relevant laws, regulations, principles and interpretations. We account for uncertainty in income taxes by recognizing the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not criteria, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.
Lease and Asset Retirement Obligations
We have entered into various non-cancelable operating lease agreements for our offices and data centers and non-cancelable finance lease agreements for property and equipment. On January 1, 2019, we adopted Topic 842 using the modified retrospective transition method. Beginning on January 1, 2019, results are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. See Note 10, Leases, for additional information on the impact of adoption of Topic 842.
Significant judgment is required when determining whether a contract is or contains a lease. We review contracts to determine whether the language conveys the right to control the use of an identified asset for a period of time in exchange for consideration.
We classify leases at their commencement as either operating or finance leases. We may receive renewal or expansion options, rent holidays, leasehold improvements or other incentives on certain lease agreements. We recognize a right-of-use asset and lease liability for all of our leases at the commencement of the lease.lease, which is the date we have the right to control the asset. Lease liabilities are measured based on the present value of the minimum lease payments discounted by a rate determined as of the date of commencement. The discount rate used to calculate the present value for lease payments is the rate implicit in the lease, unless that rate cannot be readily determined. For leases in which the rate implicit in the lease is not readily determinable, the discount rate is our incremental borrowing rate, which is determined based on information available at lease commencement and is equal to the rate of interest that we would have to pay to borrow on a collateralized basis over a similar term as the lease. Right-of-use assets are measured based on the lease liability adjusted for any initial direct costs, prepaid rent, or lease incentives. Minimum lease payments made under operating and finance leases are apportioned between interest expense and a reduction of the related operating and finance lease obligations. Operating lease costs, including interest expense on operating leases, are presented within Selling, general and administrative expense on the consolidated statements of operations and the related operating lease obligation is presented within Accrued expenses and other current liabilities and Operating lease obligations on the consolidated balance sheets. Amortization and interest expense on finance leases are presented within Selling, general and administrative expense and Other income (expense), net, respectively, on the consolidated statements of operations and the related finance lease obligation is presented within Accrued expenses and other current liabilities and Other non-current liabilities on the consolidated balance sheets.

Certain lease agreements include variable lease costs which are primarily related to costs that are dependent on our usage of the underlying asset or lease payments that are dependent on an index when that index has changed since lease commencement. Those costs are expenses in the period in which they are incurred.
We establish assets and liabilities for the present value of estimated future costs to retire long-lived assets at the termination or expiration of a lease. Such assets are amortized over the lease term, and the recorded liabilities are accreted to the future value of the estimated retirement costs. The related amortization and accretion expenses are presented within Selling, general and administrative on the consolidated statements of operations.

Sublease income is generally presented within Selling, general and administrative expense on the consolidated statements of operations.
Revenue Recognition
We recognize revenue when we satisfy a performance obligation by transferring a promised good or service to a customer. Substantially all of our performance obligations are satisfied at a point in time rather than over time. We offer goods and services through our online marketplaces in three3 primary categories: Local, Goods and Travel.
Service revenue
Service revenue primarily represents the net commissions earned from selling goods or services on behalf of third-party merchants. Those transactions generally involve a customer's purchase of a voucher through one of our online marketplaces that can be redeemed by the customer with a third-party merchant for goods or services (or for discounts on goods or services). Service revenue from those transactions is reported on a net basis as the purchase price collected from the customer less the portion of the purchase price that is payable to the third-party merchant. We recognize revenue from those transactions when our commission has been earned, which occurs when a sale through one of our online marketplaces is completed and the related voucher has been made available to the customer. We believe that our remaining obligations to remit payment to the merchant and to provide information about vouchers sold are administrative activities that are immaterial in the context of the contract with the merchant. Revenue from hotel reservation offerings is recognized at the time the reservation is made, net of an allowance for estimated cancellations. Prior to our adoption of Topic 606, we deferred the revenue from hotel reservation offerings until the customer's stay commenced.
We also earn commissions when customers make purchases with retailers using digital coupons accessed through our websites and mobile applications. We recognize those commissions as revenue in the period in which the underlying transactions between the customer and the third-party merchant are completed. Additionally, we earn advertising revenue when the advertiser's logo or website link has been included on our websites or in specified email distributions for the requisite period of time as set forth in the agreement with the advertiser.
Product revenue
We generate product revenue from our sales of first-party Goods transactions, which are direct sales of merchandise inventory to customers through our Goods category.inventory. For product revenue transactions, we are the primary party responsible for providing the good to the customer, we have inventory risk and we have discretion in establishing prices. As such, product revenue is reported on a gross basis as the purchase price received from the customer. Product revenue, including associated shipping revenue, is recognized when title passes to the customer upon delivery of the product. We fully transitioned to a third-party marketplace in North America in 2020 and in International in the fourth quarter of 2021. In a third-party marketplace model, our merchants generally assume inventory and refund risk and for those transactions we record revenue on a net basis within service revenue.
Variable Consideration for Unredeemed Vouchers
For merchant agreements with redemption payment terms, the merchant is not paid its share of the sale price for a voucher sold through one of our online marketplaces until the customer redeems the related voucher. If the customer does not redeem a voucher with such merchant payment terms, we retain all of the gross billings for that

We estimate the variable consideration from vouchers that will not ultimately be redeemed using our historical voucher redemption experience and recognize that amount as revenue at the time of sale. We only recognize amounts in variable consideration when we believeapply a constraint to ensure it is probable that a significant reversal of revenue will not occur in future periods, which requires us to make significant estimates of future redemptions.periods. If actual redemptions differ from our estimates, the effects could be material to the consolidated financial statements. As of December 31, 2019 and 2018, we constrained $14.6 million and $13.7 million in revenue from unredeemed vouchers that we may recognize in future periods when we determine it is probable that a significant amount of that revenue will not be subsequently reversed. Prior to our adoption of Topic 606, we recognized that variable consideration from unredeemed vouchers and derecognized the related accrued merchant payables when our legal obligation to the merchant expired.
Refunds
Refunds are recorded as a reduction of revenue. The liability for estimated refunds is included within Accrued expenses and other current liabilities on the consolidated balance sheets. Prior to our adoption of Topic 606, we classified refunds on service revenue transactions for which the merchant's share of the refund amount is not recoverable as a cost of revenue.

74


GROUPON, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
We estimate our refund reserve using historical refund experience by category. We assess the trends that could affect our estimates on an ongoing basis and make adjustments to the refund reserve calculations if it appears that changes in circumstances, including changes to our refund policies or general economic conditions, may cause future refunds to differ from our initial estimates. If actual refunds differ from our estimates, the effects could be material to the consolidated financial statements.
Discounts, Customer Credits and Other Consideration Payable to Customers
We provide discount offers to encourage purchases of goods and services through our online marketplaces. We record discounts as a reduction of revenue.
Additionally, we issue credits to customers that can be applied to future purchases through our online marketplaces. Credits are primarily issued as consideration for refunds. To a lesser extent, credits are issued for customer relationship purposes. Credits issued to satisfy refund requests are applied as a reduction to the refundsrefund reserve and customer credits issued for relationship purposes are classified as a reduction of revenue. Prior to our adoption of Topic 606, we classified credits issued to consumers for relationship purposes as a marketing expense. Breakage income from customer credits that are not expected to be used is estimated and recognized as revenue in proportion to the pattern of redemption for customer credits that are used. Prior to
Customer credits can be redeemed through our adoption of Topic 606, we recognized breakage incomeonline marketplaces for unusedgoods or services provided by a third-party merchant or for merchandise inventory sold by us. When customer credits when they expiredare redeemed for goods or were forfeited.services provided by a third-party merchant, service revenue is recognized on a net basis as the difference between the carrying amount of the customer credit liability derecognized and the amount due to the merchant for the related transaction. When customer credits are redeemed for merchandise inventory sold by us, product revenue is recognized on a gross basis equal to the amount of the customer credit liability derecognized.
Sales and Related Taxes
Sales, use, value-added and related taxes that are imposed on specific revenue-generating transactions are presented on a net basis and excluded from revenue.
Costs of Obtaining Contracts
Incremental costs to obtain contracts with third-party merchants, such as sales commissions, are deferred and recognized on a straight-line basis over the expected period of the merchant arrangement, generally from 12 to 18 months. Those costs are classified within Selling, general and administrative expensesexpense in the consolidated statements of operations. Prior to our adoption of Topic 606, we expensed the incremental costs to obtain contracts with third-party merchants, such as sales commissions, as incurred.

Cost of Revenue
Cost of revenue is comprised of direct and certain indirect costs incurred to generate revenue. Costs incurred to generate revenue, which include credit card processing fees, editorial costs, compensation expense for technology support personnel who are responsible for maintaining the infrastructure of our websites, amortization of internal-use software relating to customer-facing applications, web hosting and other processing fees are attributed to the cost of service and product revenue in proportion to gross billings during the period. For product revenue transactions, cost of revenue also includes the cost of inventory, shipping and fulfillment costs and inventory markdowns. Fulfillment costs are comprised of third-party logistics provider and other costs as well asand, prior to fully impairing our fulfillment center in 2020, rent, depreciation, personnel costs and other costs of operating our fulfillment center.
Impairment of Long-Lived Assets
We review our long-lived assets, such as property, equipment and software, intangible assets and right-of-use assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If circumstances require that a long-lived asset or asset group to be held and used be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that long-lived asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value.

GROUPON, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Long-lived assets or disposal groups classified as held for sale are recorded at the lower of their carrying amount or fair value less estimated selling costs. Long-lived assets are not depreciated or amortized while classified as held for sale.
Stock-Based Compensation
We measure stock-based compensation cost at fair value. Expense is generally recognized on a straight-line basis over the service period during which awards are expected to vest, except for awards with both performance conditions and a graded vesting schedule, which are recognized using the accelerated method. We present stock-based compensation expense within the consolidated statements of operations based on the classification of the respective employees' cash compensation. See Note 13, Compensation Arrangements.
Foreign Currency
Balance sheet accounts of our operations outside of the United States are translated from foreign currencies into U.S. dollars at exchange rates as of the consolidated balance sheet dates. Revenue and expenses are translated at average exchange rates during the period. Foreign currency translation adjustments and foreign currency gains and losses on intercompany balances that are of a long-term investment nature are included within Accumulated other comprehensive income on the consolidated balance sheets. Foreign currency gains and losses resulting from transactions that are denominated in currencies other than the entity's functional currency, including foreign currency gains and losses on intercompany balances that are not of a long-term investment nature, are included within Other income (expense), net on the consolidated statements of operations.
Business Combinations
The results of businesses acquired are included in the consolidated financial statements beginning on the respective acquisition dates. The fair value of consideration transferred in business combinations is allocated to the tangible and intangible assets acquired and liabilities assumed at the acquisition date, with the remaining unallocated amount recorded as goodwill. Acquired goodwill represents the premium paid over the fair value of the net tangible and intangible assets acquired. We may pay a premium for a number of reasons, including growing our merchant base and acquiring an assembled workforce. The goodwill from business combinations is generally not deductible for tax purposes.

3. DISCONTINUED OPERATIONSCOVID-19 PANDEMIC
In October 2016, we completedSince March 2020, the COVID-19 pandemic has led to a strategic reviewsignificant decrease in consumer demand and active customers, a decrease in customer redemptions, and elevated refund levels due to changes in consumer behavior and protective measures taken to control the spread of our international markets in connection with our efforts to optimize our global footprint and focus on the markets that we believe have the greatest potential to benefit our long-term financial performance. Based on that review, we decided to focus our business on 15 core countries and to pursue strategic alternatives for our operations in the remaining 12 countries, which were primarily based in Asia and Latin America.COVID-19. The dispositions of our operations in those 12 countries were completed between November 2016 and March 2017.
A business disposition that represents a strategic shift andCOVID-19 pandemic has (or will have) a major effecthad an adverse impact on our operations and financial results is reported as a discontinued operation. We determined that the decision reached by management and our Board of Directors to exit those 12 non-core countries, which comprised a substantial majority of the operations outside of North America and EMEA (Europe, the Middle East and Africa), represented a strategic shift in our business. Additionally, based on our review of quantitative and qualitative factors relevant to the dispositions, we determined that the disposition of the businesses in those countries would have a major effect on our operations and financial results. As such, thecondition, results of operations and cash flows, forwhich included impairments of our goodwill and long-lived assets.
Recovery from the COVID-19 pandemic has been and could continue to be volatile and prolonged given the unprecedented and continuously evolving nature of the situation and the emergence and spread of new variants.

The following table summarizesIn April 2020, the major classesBoard approved a multi-phase restructuring plan related to our previously-announced strategic shift and as part of line itemsthe cost cutting measures implemented in response to the impact of COVID-19 on our business. Actions taken under our restructuring plan changed how we used certain long-lived assets and required us to evaluate those long-lived assets for impairment, which resulted in impairments of our long-lived assets. These impairments are included in Restructuring and related charges on the consolidated statement of operations. See Note 14, Restructuring and Related Charges, for more information.
COVID-19 impacted the financial performance of our investees and resulted in an impairment of an Other equity investment and a loss on a fair value option investment that are included in Other income (loss) from discontinued(expense), net on the consolidated statement of operations net of tax, for the years ended December 31, 2019 and 2017 (in thousands).There was no activity related to discontinued operations forduring the year ended December 31, 2018.

The primary purpose of this acquisition was to expand digital coupon offeringsestimates used in our International segment. The transaction included a contingent consideration arrangement with an acquisition-date fair value measurements, which could result in additional impairment of $1.6 million. In addition, concurrent with the acquisition, we entered into an agreement with the noncontrolling shareholdergoodwill and long-lived assets in future periods that gave us the right to acquire and the noncontrolling shareholder's right to put to us the remaining outstanding shares of Cloud Savings in December 2018. The acquisition-date fair value of the right and obligation to acquire the remaining outstanding shares of $8.6 million was initially recorded asmay have a financing obligation and classified within Accrued expenses and other current liabilitiesmaterial effect on the consolidated balance sheets.

(2)
Represents the reclassification between Right-of-use assets - operating leases, net and Goodwill due to an adjustment in the allocation of impairments recorded in 2020 between those two accounts.
In order to evaluate goodwill for impairment, we compare the fair values of our 2 reporting units, North America and International, to their carrying values. In determining the fair values of our reporting units, we use the discounted cash flow method under the income approach and the market multiple valuation approach that use Level 3 inputs.
During the third quarter of 2021, we evaluated our goodwill for impairment due to the circumstances described in Note 3, COVID-19 Pandemic. The fair value of the reporting units exceeded the carrying value, therefore we concluded that goodwill was not impaired for either of our reporting units. Additionally, we performed our annual goodwill impairment assessment as of October 1, 2021 and determined no reporting units' carrying values were in excess of their estimated fair values. Therefore, we did not recognize goodwill impairment for any of our reporting units during the year ended December 31, 2021.
During the first quarter 2020, we recognized goodwill impairment, as shown in the table above, due to the circumstances described in Note 3, COVID-19 Pandemic, within our International segment related to our EMEA operations. We did not recognize any goodwill impairment in our North America or Asia Pacific reporting units.
During the third quarter 2020, we exited our operations in Japan and New Zealand as part of our restructuring plan, which represents the majority of the countries in our Asia Pacific reporting unit. As a result, we combined the remainder of the Asia Pacific reporting unit and the EMEA reporting unit into a single International reporting unit, consistent with how management reviews the operating results of the business. As a result of the change in reporting units, we performed a qualitative assessment of potential goodwill impairment for the new International reporting unit and performed separate qualitative assessments of potential goodwill impairment for our Asia Pacific and EMEA reporting units immediately prior to the change. Based on those assessments, we determined that the likelihood of a goodwill impairment did not reach the more-likely-than-not threshold. Accordingly, we concluded that goodwill relating to those reporting units was not impaired and further quantitative testing was not required to be performed.
There was no goodwill impairment for the yearsyear ended December 31, 2019, 2018 and 2017.

Fair Value Option Investments    
In connection with the dispositions of controlling stakes in Ticket Monster, an entity based in the Republic of Korea, and Groupon India in prior periods, we obtained minority investments in Monster Holdings LP ("Monster LP") and in Nearbuy Pte Ltd. ("Nearbuy"). We have made an irrevocable election to account for both of those investments at fair value with changes in fair value reported in earnings. We elected to apply fair value accounting to those investments because we believe that fair value is the most relevant measurement attribute for those investments, as well as to reduce operational and accounting complexity. Our election to apply fair value accounting to those investments has and may continue to cause fluctuations in our earnings from period to period.
We determined that the fair value of our investments in Monster LP and Nearbuy was $0.0 million and $1.4 million as of December 31, 2019, and $69.4 million and $4.5 million as of December 31, 2018.

Monster LP
In 2015, we completed the sale of a controlling stake in Ticket Monster to an investor group, whereby we contributed all of the issued and outstanding share capital of Ticket Monster to Monster LP in exchange for Class B units of Monster LP, a newly-formed limited partnership, and $285.0 million in cash consideration. In February 2017, we participated in a recapitalization transaction with Monster LP whereby it exchanged all of its Class B units for

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

16,609,195 newly issued Class A-1 units. Upon closing of the transaction, we own 57% of the outstanding Class A-1 units, which represents 9% of the total outstanding partnership units.
Following the February 2017 recapitalization transaction, the Class A-1 units are entitled to an $150.0 million liquidation preference, including an $85.0 million liquidation preference attributable to the Class A-1 units held by us, which must be paid prior to any distributions to the holders of the Class A-2, Class B and Class C units. Class A-1 unit holders are also entitled to share in distributions between $950.0 million and $1,494.0 million in accordance with the terms of Monster LP's distribution waterfall and in distributions in excess of $1,494.0 million based on their pro rata ownership of total outstanding partnership units. As a result of the February 2017 recapitalization transaction, we currently hold an investment in the most senior equity units in Monster LP’s capital structure. However, while providing more downside protection, those Class A-1 units provide less opportunity for appreciation than the Class B units previously held by us.
During the first quarter of 2019 we recognized a $41.5$69.4 million loss from changes in the fair value of our investment in Monster LP mainly due to the revised cash flow projections provided by TMON in March 2019 and an increase in the discount rate applied to those forecasts, which increased to 26.0% as of March 31, 2019, as compared with 21.0% as of December 31, 2018. The increase in the discount rate applied as of March 31, 2019 was due to the deterioration in the financial condition of TMON and the competitive environment in the Korean e-commerce industry, which resulted in an increase to financial projection risk. During the second quarter of 2019, we recognized an additional loss of $27.9 million from changes in the fair value of our investment in Monster LP due to revised financial projections provided by TMON in June 2019.forecasts. The revisions to the financial projections were made as a result of TMON’sdue to the deterioration in Monster LP's financial condition and continued underperformance as compared with prior projections along with adjustments to their business model.

Nearbuy
In 2015, Groupon India completed an equity financing transaction with a third-party investor that obtained a majority voting interest in the entity, whereby (a) the investor contributed $17.0 million in cash to Nearbuy, a newly formed Singapore-based entity, in exchange for Series A Preference Shares and (b) we contributed the shares of Groupon India to Nearbuy in exchange for seed preference shares of Nearbuy. In January 2017, Nearbuy issued additional Series A Preference Shares to its controlling investor for total proceeds of $3.0 million. Upon closing of that transaction, the Series A Preference Shares are entitled to a $20.0 million liquidation preference, which must be paid prior to any distributions to other equity holders. In December 2017, Nearbuy sold its subsidiary Nearbuy India Pte Ltd., which represented substantially all of its business operations, to a third-party investor in exchange for a minority investment in the acquirer. During the fourthfirst quarter of 2019,2020, we recognized a $3.1$1.4 million loss from changes in the fair value of our investment in Nearbuy due to the revised cash flow projections providedand an increase in the discount rate applied to those forecasts. The revisions to the financial projections were due to the deterioration in the financial condition of Nearbuy as a result of COVID-19, which resulted in underperformance as compared with prior projections and an increase to financial projection risk. In 2019, we recognized a $3.1 million loss from changes in the fair value of our investment in Nearbuy due to revised cash flow projections. There was no activity recorded for this investment for the year ended December 2019.

9.8. FINANCING ARRANGEMENTS
Adoption of ASU 2020-06
On January 1, 2021, we early adopted ASU 2020-06 using the modified retrospective method. The ASU eliminates the requirement to separately recognize an equity component when accounting for convertible debt that may be cash-settled upon conversion or convertible instruments with a beneficial conversion feature. Additionally, the ASU removes certain conditions for equity classification related to contracts in an entity’s own equity (e.g., warrants) and amends certain guidance related to the computation of income (loss) per share for convertible instruments and contracts in an entity’s own equity.
Beginning January 1, 2021, our consolidated financials are presented in accordance with ASU 2020-06, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. The new guidance changed the accounting for our 3.25% Convertible Senior Notes, due 2022, as discussed below.
On3.25% Convertible Senior Notes due 2022
In April 4, 2016, we issued $250.0 million in aggregate principal amount of convertible senior notes (the "Notes""Atairos Notes") in a private placement to A-G Holdings, L.P. ("AGH"). Michael Angelakis,In May 2021, we repurchased the chairmanAtairos Notes for an

aggregate purchase price equal to $255.0 million, consisting of the $250.0 million outstanding principal amount, $1.0 million of accrued interest through the repurchase date and chief executive officera $4.0 million prepayment penalty. In the second quarter 2021, we recognized a $5.1 million loss on the early extinguishment of the Atairos Group, Inc. ("Atairos")Notes, which is presented in Other income (expense), joined our Boardnet on the consolidated statements of Directors (the "Board")operations.
Prior to the adoption of ASU 2020-06, we separated the Atairos Notes into their liability and equity components. The liability was initially calculated by measuring the fair value of similar liability without an associated conversion feature. The difference between the principal amount of the Atairos Notes and the liability component was recognized in connection withequity, effectively resulting in a debt discount. We incurred transactions costs of $6.8 million related to the issuance of the Atairos Notes. Transaction costs attributable to the liability component of $4.8 million were also recorded as a debt discount in the consolidated balance sheets. The debt discount was amortized to interest expense over the terms of the Atairos controlsNotes. Together with cash interest, this resulted in an effective interest rate of 9.75%. Transaction costs attributable to the voting powerequity component of AGH.$2.0 million were recorded in stockholders' equity as a reduction of the equity component.
Following the adoption of ASU 2020-06, the previously bifurcated equity component of our Atairos Notes was recombined with the liability component, resulting in a single liability-classifed instrument. The carrying value of the Atairos Notes at the transition was determined by recalculating the basis of the notes as if the conversion option had not been bifurcated at issuance. Transaction costs related to the issuance of the Atairos Notes that were allocated to the equity component were reclassified out of Additional paid-in capital and the amortization and the related debt discount associated with these costs was recalculated through the transition date. This resulted in an effective interest rate of 3.76%.
The carrying amount of the Atairos Notes consisted of the following as of December 31, 2020 (in thousands):
December 31, 2020
Liability component:
Principal amount$250,000 
Less: debt discount - transaction costs(1,459)
Less: debt discount - equity(19,051)
Net carrying amount of liability component$229,490 
Net carrying amount of equity component$67,014 
We classified the fair value of the Atairos Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the terms of the Atairos Notes and our cost of debt. The estimated fair value of the Atairos Notes as of December 31, 2020 was $263.3 million, and was determined using a lattice model.
During the years ended December 31, 2021, 2020 and 2019, we recognized interest costs on the Atairos Notes as follows (in thousands):
Year Ended December 31,
202120202019

Total$3,475 $22,749 $21,328 
Note Hedges and Warrants
In May 2016, we purchased convertible note hedges with respect to our common stock for a cost of $59.1 million from certain bank counterparties. The convertible note hedges were intended to reduce the potential economic dilution upon conversion of the Atairos Notes. We also sold warrants for total cash proceeds of $35.5 million to certain bank counterparties.

86


GROUPON, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The amounts paid and received for the convertible note hedges and warrants were recorded in Additional paid-in capital in the consolidated balance sheets as of December 31, 2020. The convertible note hedges and warrants were not remeasured as long as they continue to meet the condition for equity classification. The amounts paid for the convertible note hedges were tax deductible over the term of the Atairos Notes, while the proceeds received from the warrants were not taxable.
Under the if-converted method, the shares of common stock underlying the conversion option in the Atairos Notes are included in the diluted income (loss) per share denominator and the interest expense and amortization of the transaction costs on the Atairos Notes, net of tax, is added to the numerator. Taken together, the purchase of the convertible note hedges and sale of warrants offset any actual dilution from the conversion of the Atairos Notes and increased the overall conversion price from $108.00 to $170.00 per share.
In connection with the repurchase of the Atairos Notes, we entered into agreements (collectively "the Unwind Agreements") with each of the bank counterparties in May 2021 to unwind the convertible note hedges and warrants. Pursuant to the terms of the Unwind Agreements, we received cash proceeds of $2.3 million for the settlement of the convertible note hedges and paid cash consideration of $1.3 million for the settlement of the warrants.
1.125% Convertible Senior Notes due 2026
In March and April 2021, we issued $230.0 million aggregate principal amount of convertible senior notes due 2026 (the "2026 Notes") in a private offering to qualified institutional buyers. The net proceeds from this offering were $243.2 million after deducting issuance costs.$222.1 million. The 2026 Notes bear interest at a rate of 3.25%1.125% per annum, payable annuallysemiannually in arrears on April 1March 15 and September 15 of each year, beginningwhich began on April 1, 2017.September 15, 2021. The 2026 Notes will mature on April 1, 2022,March 15, 2026, subject to earlier conversionrepurchase, redemption or redemption.conversion.
We used $27.4 million of the net proceeds from the offering to pay the cost of certain related capped call transactions and used the remaining net proceeds, together with cash on hand, to repurchase the Atairos Notes.
Each $1,000 of principal amount of the 2026 Notes initially is convertible into 185.185214.6800 shares of common stock, which is equivalent to an initial conversion price of $5.40$68.12 per share, subject to adjustment upon the occurrence of specified events. In addition, upon the occurrence of a make-whole fundamental change, as defined in the Indenture governing the 2026 Notes (the "Indenture"), or if we issue a notice of redemption, we will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its 2026 Notes in connection with such make-whole fundamental change or redemption.
Upon conversion, we can elect to settle the conversion value in cash, shares of our common stock, or any combination of cash and shares of our common stock. HoldersSubject to certain conditions, holders of the 2026 Notes may convert theirthe 2026 Notes at their option at any time until the close of business on the scheduled trading day immediately preceding the maturity date. In addition, if specified corporate events occur prior to the maturity date, we may be required to increase the conversion rate for holders who elect to convert based on the effective date of such event and the applicable stock price attributable to the event, as set forth in a table contained in the indenture governing the Notes (the "Indenture").event. Based on the closing price of the common stock of $2.39$23.16 as of December 31, 2019,2021, the if-converted value of the 2026 Notes was less than the principal amount.
With certain exceptions,Certain conditions apply to the conversion by holders and redemption by us of the 2026 Notes, which are set forth in the Indenture governing the 2026 Notes. In addition, upon the occurrence of a fundamental change (as defined in the Indenture), prior to the maturity date, holders of the Notes may require us to repurchase all or a portion of theirthe 2026 Notes for cash at a purchase price equal to the principal amount plus accrued and unpaid interest. In addition, we may redeem the Notes, at our option, at a purchase price equal to the principal amount plus accrued and unpaid interest on or after April 1, 2020, if the closing sale price of the common stock exceeds 150% of the then-current conversion price for 20 or more trading days in the 30 consecutive trading-day period preceding the exercise of this redemption right.cash.
The 2026 Notes are our senior unsecured obligations that rank equal in right of payment to all senior unsecured indebtedness and will rank senior in right of payment to any of our indebtedness that is contractuallyexpressly subordinated in right of payment to the Notes.2026 Notes; equal in right of payment to any of our unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities of current or future subsidiaries (including trade payables).
The Indenture includes customary events of default. If an event of default, as defined in the Indenture, occurs and is continuing, the principal amount of the 2026 Notes and any accrued and unpaid interest may be declared immediately due and payable. In the case of bankruptcy or insolvency, the principal amount of the 2026 Notes and any accrued and unpaid interest would automatically become immediately due and payable.
We have separated the Notes into their liability and equity components in the accompanying consolidated balance sheets. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Notes. The difference between the principal amount of the Notes and the liability component (the "debt discount") is amortized to interest expense at an effective interest rate of 9.75% over the term of the Notes. The equity component of the Notes is included in additional paid-in capital in the consolidated balance sheets and is not remeasured as long as it continues to meet the conditions for equity classification.

We incurred transaction costs of approximately $6.8 million related to the issuance of the Notes. Those transaction costs were allocated to the liability and equity components in the same manner as the allocation of the proceeds from the Notes. Transaction costs attributable to the liability component of $4.8 million were recorded as a debt discount in the consolidated balance sheet and are being amortized to interest expense over the term of the Notes. Transaction costs attributable to the equity component of $2.0 million were recorded in stockholders' equity as a reduction of the equity component.87

We account for the 2026 Notes as a single liability-classified instrument measured at amortized cost due to the adoption of ASU 2020-06. The carrying value of the 2026 Notes was determined by deducting transaction costs incurred in connection with the issuance of the 2026 Notes of $7.8 million from the principal amount. Those transaction costs were recorded as a debt discount in the consolidated balance sheets and are amortized to interest expense. Together with the cash interest, this results in an effective interest rate of 1.83% over the term of the 2026 Notes. We have presented the 2026 Notes in non-current liabilities in the accompanying consolidated balance sheets.
The carrying amount of the 2026 Notes consisted of the following as of December 31, 2019 and 20182021 (in thousands):

The estimated fair value of the Notes as of December 31, 2019 and 2018 was $262.7 million and $257.1 million, and was determined using a lattice model. We classified the fair value of the 2026 Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the 2026 Notes and our cost of debt.

Note Hedges and WarrantsCapped Call Transactions
In May 2016,March and April 2021, in connection with the offering of the 2026 Notes, we purchased convertible note hedgesentered into privately-negotiated capped call transactions with respecteach of Barclays Bank PLC, BNP Paribas and Mizuho Markets Americas LLC. The capped call transactions cover, subject to customary adjustments, the number of shares of common stock initially underlying the 2026 Notes. The capped call transactions are expected generally to reduce potential dilution to our common stock forupon any conversion of the 2026 Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes, with such reduction and/or offset subject to a costcap initially equal to $104.80 (which represents a premium of $59.1 million from certain bank counterparties.

The warrants expire on various dates between July 1, 2022 and August 26, 2022 and are exercisable on their expiration dates.

The 2019 Credit Agreement replaced our previous $250.0 million amended and restated

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
In July 2020, we entered into an amendment to the revolving credit agreement (the "2016"First Amendment") in order to provide us with, among other things, operational flexibility and covenant relief through the end of the first quarter of 2021 in light of the ongoing impacts of COVID-19 on our business. In addition to the covenant relief described below, the First Amendment permanently reduces borrowing capacity under our senior secured revolving credit facility from $400.0 million to $225.0 million.
In March 2021, we entered into a second amendment to the revolving credit agreement (the "Second Amendment," together with the First Amendment, the "Amendments") to extend the suspension period provided by the First Amendment through the fourth quarter 2021 (unless terminated by us prior to then) (the "Suspension Period"), amend and remove certain financial covenants applicable after the amended Suspension Period ends and permit the issuance of the 2026 Notes and related capped call transactions. We collectively refer to the revolving credit agreement as amended by the Amendments as the "Amended Credit Agreement"). We voluntarily elected to early terminate the Suspension Period as of the third quarter of 2021.
We deferred debt issuance costs of $2.4$3.5 million related toas a result of entering into the 2019Amended Credit Agreement. Those deferredDeferred debt issuance costs are included within Other non-current assets on the consolidated balance sheetsheets as of December 31, 20192021 and will beare amortized to interest expense over the term of the respective agreement.
BorrowingsPursuant to the Amendments, during the Suspension Period, we were exempt from certain covenant restrictions, namely the requirements to maintain a maximum funded indebtedness to Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA") ratio and a minimum liquidity balance (including any undrawn amounts under the 2019credit facility) of at least 70.0% of our accrued merchant and supplier payables balance (which covenant applies again beginning in the third quarter 2021 following our voluntary early termination on the Suspension Period). Additionally, the Amendments provide that, during the Suspension Period, we were required to maintain specified minimum quarterly EBITDA levels and to maintain a monthly minimum liquidity balance (including any undrawn amounts under the credit facility) of at least 100.0% of our accrued merchant and supplier payables balance for such month plus $50.0 million. The Second Amendment also permanently removes requirements that we maintain (i) a maximum senior secured indebtedness to EBITDA ratio and (ii) unrestricted cash of not less than $250.0 million. Finally, the Second Amendment changes the requirement to maintain a minimum fixed charge coverage ratio to a requirement to maintain a minimum interest coverage ratio. Following our voluntary early termination of the Suspension Period, we are subject to the ordinary course covenants under the Amended Credit Agreement bearbeginning in the third quarter 2021.
In addition, under the Amended Credit Agreement, we are subject to various covenants, including customary restrictive covenants that limit our ability to, among other things: incur additional indebtedness; make dividend and other restricted payments, including limiting the amount of our share repurchases; enter into sale and leaseback transactions; make investments, loans or advances; grant or incur liens on assets; sell assets; engage in mergers, consolidations, liquidations or dissolutions; and engage in transactions with related parties and other affiliates. The Amendments further restricts certain of these negative covenants during the Suspension Period, including our ability to make share repurchases, acquisitions, investments and to incur additional indebtedness and liens.
As of December 31, 2021, we were in compliance with the applicable covenants under our Amended Credit Agreement. Non-compliance with the covenants under the Amended Credit Agreement may result in termination of the commitments thereunder and any then outstanding borrowings may be declared due and payable immediately. We have the right to terminate the Amended Credit Agreement or reduce the available commitments at any time.
The Amendments also increased interest at our option,rates through the end of the Suspension Period (i.e., through the third quarter 2021), raising the alternative base rate and Canadian prime spreads to 1.50%, the fixed rate spreads to 2.50% and the commitment fee to 0.40% on the daily amount of the unused commitments under the Amended Credit Agreement. Following the Suspension Period, the applicable spread and commitment fee will revert to pre-Amendment levels, which provides for (a) interest at a rate per annum equal to (a)(i) an adjusted LIBO rate or (b)(ii) a customary base rate (with loans denominated in certain currencies bearing interest at rates specific to such currencies) plus an additional margin ranging between 0.50% and 2.00%. We are required to pay quarterly and (b) commitment fees ranging from 0.25% to 0.35% per annum ofon the average daily amount of unused commitments available under the 2019 Credit Agreement.commitments. The 2019Amended Credit Agreement also includes a replacement mechanism for the discontinuation of the adjusted LIBO rate.

10.9. LEASES
Adoption of ASC Topic 842, Leases
On January 1, 2019, we adopted ASC Topic 842 using the modified retrospective transition method. Topic 842 requires the recognition of lease assets and liabilities for operating leases, in addition to the finance lease assets and liabilities previously recorded on our consolidated balance sheets. Beginning on January 1, 2019, our consolidated financial statements are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. The modified retrospective transition method required the cumulative effect, if any, of initially applying the guidance to be recognized as an adjustment to our accumulated deficit as of our adoption date. As a result of adopting Topic 842, we recognized additional lease assets and liabilities of $109.6 million as of January 1, 2019. The discount rate used to calculate that adjustment was the rate implicit in the lease, unless that rate was not readily determinable. For leases for which the rate was not readily determinable, the discount rate used was our incremental borrowing rate as of the adoption date, January 1, 2019. There was 0 cumulative effect adjustment to our accumulated deficit as a result of initially applying the guidance. Aside from the impact to our consolidated balance sheet discussed above, lease accounting policies and presentation within the consolidated statement of operations and consolidated statements of cash flows is substantially consistent with historical treatment.
We elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed us to carry forward prior conclusions about lease identification, classification and initial direct costs for leases entered into prior to adoption of Topic 842. Additionally, we elected to not separate lease and non-lease components for all of our leases. For leases with a term of 12 months or less, we elected the short-term lease exemption, which allowed us to not recognize right-of-use assets or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future.
General Description of Leases
We have entered into various non-cancelable operating lease agreements for our offices and data centers and non-cancelable finance lease agreements for property and equipment. We classify leases at their commencement as either operating or finance leases. We may receive renewal or expansion options, rent holidays, leasehold improvements or other incentives on certain lease agreements.
Our operating leases primarily consist of leases for real estate throughout the world with lease expirations between 20202022 and 2026.2027. These arrangements typically do not transfer ownership of the underlying asset as we do not assume, nor do we intend to assume, the risks and rewards of ownership. Our finance leases are related to purchases of property and equipment, primarily computer hardware, with expirations between 2020 and 2023. We have also subleased certain office facilities under operating lease agreements, with expirations between 2023 and 2026.all of which expire in 2022.
We lease our headquarters located in Chicago, Illinois ("600 West Chicago"). Our lease agreement for 600 West Chicago through January 31, 2026. We sublease a portion of that space to Uptake, Inc., a Lightbank LLC portfolio company as a related party transaction. The sublease was a market rate transaction on terms that we believe are no less favorable than would have been reached with an unrelated party. The sublease extends through January 31, 2026 and includes rent escalations that range from one to two percent per year, as well as expansion options and a five-year renewal option. The 600 West Chicago lease represents $79.4 million ofsublease rentals over the estimated future paymentsentire term total $18.2 million. We have also subleased other office facilities under operating lease agreements with expirations between 2023 and 2026 that are not significant.

Legal Matters and Other Contingencies
From time to time, we are party to various legal proceedings incident to the operation of our business. For example, we currently are involved in proceedings brought by former employeesmerchants, employment and merchants,related matters, intellectual property infringement suits, customer lawsuits, stockholder claims relating to U.S. securities law, consumer class actions and suits alleging, among other things, violations of state consumer protection or privacy laws.
On April 28, 2020, an individual plaintiff filed a securities fraud class action complaint in the United States District Court for the Northern District of Illinois, and in July 2020, another individual was appointed as lead plaintiff ("Securities Lawsuit"). The lawsuit covers the time period from July 30, 2019 through February 18, 2020. The lead plaintiff alleges that Groupon and certain of its officers made materially false and/or misleading statements or omissions regarding its business, operations and prospects, specifically as it relates to reiterating its full year guidance on November 4, 2019 and the Groupon Select program. Plaintiff seeks unspecified compensatory damages and attorneys' fees. Discovery has now commenced in this matter. We intend to continue to vigorously defend the case, which we believe to be without merit.
In addition, 3 shareholders have filed separate shareholder derivative lawsuits in relation to the same events that are the subject of the securities litigation described above (collectively, the “Derivative Lawsuits”). First, on September 9, 2021, a shareholder named Jonathan Frankel filed a federal derivative lawsuit in the United States District Court for District of Delaware. Second, on January 19, 2022, a shareholder named Alyssa Estreen filed a derivative lawsuit in the Court of Chancery in the State of Delaware. Finally, on January 24, 2022, a shareholder named Saman Khoury filed a derivative lawsuit, also in the Court of Chancery in the State of Delaware. All 3 lawsuits name Groupon and certain of the Company's former and current officers and directors. The allegations in all 3 Derivative Lawsuits relate to the same time period and events that are the subject of the Securities Lawsuit and allege that the Company and its shareholders have sustained damages as a result of the conduct of certain current and former officers and directors. The Plaintiffs in each of these Derivatives Lawsuits seek unspecified damages they allege were sustained by the Company, injunctive and equitable relief and attorneys' fees.

In addition, third parties have from time to time claimed, and others may claim in the future, that we have infringed their intellectual property rights. We are subject to intellectual property disputes, including patent infringement claims, and expect that we will continue to be subject to intellectual property infringement claims as our services expand in scope and complexity. In the past, we have litigated such claims, and we are presently involved in several patent infringement and other intellectual property-related claims, including pending litigation or trademark disputes relating to, for example, our Goods category, some of which could involve potentially substantial claims for damages or injunctive relief. We may also become more vulnerable to third-party claims as laws such as the Digital Millennium Copyright Act are interpreted by the courts, and we become subject to laws in jurisdictions where the underlying laws with respect to the potential liability of online intermediaries are either unclear or less favorable. We believe that additional lawsuits alleging that we have violated patent, copyright or trademark laws willmay be filed against us. Intellectual property claims, whether meritorious or not, are time consuming and often costly to resolve, could require expensive changes in our methods of doing business or the goods we sell, or could require us to enter into costly royalty or licensing agreements.
We also are subject to consumer claims or lawsuits relating to alleged violations of consumer protection or privacy rights and statutes, some of which could involve potentially substantial claims for damages, including statutory or punitive damages. Consumer and privacy relatedprivacy-related claims or lawsuits, whether meritorious or not, could be time consuming, result in costly litigation, damage awards, fines and penalties, injunctive relief or increased costs of doing business through adverse judgment or settlement, or require us to change our business practices, sometimes in expensive ways.
We are also subject to, or in the future may become subject to, a variety of regulatory inquiries, audits, and investigations across the jurisdictions where we conduct our business, including, for example, inquiries related to consumer protection, employment matters and/or hiring practices, marketing practices, tax, unclaimed property and privacy rules and regulations. Any regulatory actions against us, whether meritorious or not, could be time consuming, result in costly litigation, damage awards, fines and penalties, injunctive relief or increased costs of doing business through adverse judgment or settlement, require us to change our business practices in expensive ways, require significant amounts of management time, result in the diversion of significant operational resources, materially damage our brand or reputation, or otherwise harm our business.
We establish an accrued liability for loss contingencies related to legal and regulatory matters when the loss is both probable and reasonably estimable. Those accruals represent management's best estimate of probable losses and, in such cases, there may be an exposure to loss in excess of the amounts accrued. For certain of the matters described above, there are inherent and significant uncertainties based on, among other factors, the stage of the proceedings, developments in the applicable facts of law, or the lack of a specific damage claim. However, we believe

GROUPON, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

that the amount of reasonably possible losses in excess of the amounts accrued for those matters would not have a material adverse effect on our business, consolidated financial position, results of operations or cash flows. Our accrued liabilities for loss contingencies related to legal and regulatory matters may change in the future as a result of new developments, including, but not limited to, the occurrence of new legal matters, changes in the law or regulatory environment, adverse or favorable rulings, newly discovered facts relevant to the matter, or changes in the strategy for the matter. Regardless of the outcome, litigation and other regulatory matters can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
Indemnifications
In October 2016, we completed a strategic review of our international markets and decided to pursue strategic alternatives for our operations in 12 countries, which were primarily based in Asia and Latin America. In connection with the disposition of our operations in Latin America in the first quarter of 2017, (see Note 3Discontinued Operations), we recorded $5.4 million in indemnification liabilities for certain tax and other matters upon the closing of the transactions as an adjustment to the net loss on the dispositions within discontinued operations at their fair value. We estimated the indemnification liabilities using a probability-weighted expected cash flow approach. In 2020 and 2019, we decreased our indemnification liabilities due to the expiration of certain indemnification obligations. The resulting benefit of $0.4 million and $2.2 million is recorded within Income (loss) from discontinued operations on the consolidated statementstatements of operations for the yearyears ended December 31, 2020 and 2019. Our remaining indemnification liabilities were $3.2$2.8 million as of December 31, 2019.2021. We estimate that the total amount of obligations that are reasonably possible to arise under the indemnifications in excess of amounts accrued as of December 31, 20192021 is approximately $13.3$11.7 million.

GROUPON, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
For the years ended December 31, 2021, 2020 and 2019, we recognized $0.0 million, $0.4 million and $2.6 million in income (loss) from discontinued operations, net of tax primarily for gains related to the expiration of certain contingent liabilities under indemnification agreements.
In the normal course of business to facilitate transactions related to our operations, we indemnify certain parties, including employees, lessors, service providers, merchants, and counterparties to investment agreements and asset and stock purchase agreements with respect to various matters. We have agreed to hold certain parties harmless against losses arising from a breach of representations or covenants, or other claims made against those parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. We are also subject to increased exposure to various claims as a result of our divestitures and acquisitions, particularly in cases where we are entering into new businesses in connection with such acquisitions. We may also become more vulnerable to claims as we expand the range and scope of our services and are subject to laws in jurisdictions where the underlying laws with respect to potential liability are either unclear or less favorable. In addition, we have entered into indemnification agreements with our officers, directors and underwriters, and our bylaws contain similar indemnification obligations that cover officers, directors, employees and other agents. 
Except as noted above, it is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, any payments that we have made under these agreements have not had a material impact on our operating results, financial position or cash flows.
12.11. STOCKHOLDERS' EQUITY
Reverse Stock Split
On June 9, 2020, our stockholders approved amendments to our Restated Certificate of Incorporation to effect a reverse stock split of our shares of common stock, and our Board approved a final reverse stock split ratio of 1-for-20 and a corresponding reduction in the number of authorized shares of our common stock. The reverse stock split became effective on June 10, 2020. On the effective date, every 20 shares of issued and outstanding common stock were combined and converted into one issued and outstanding share of common stock. The number of authorized shares of Common Stock was reduced proportionately. Fractional shares were cancelled and stockholders received cash in lieu thereof and the par value per share of common stock remains unchanged. A proportionate adjustment was also made to the maximum number of shares of common stock issuable under the Groupon, Inc.

The Market-based Performance Share Units will vest if our average daily closing stock price is equal to or greater than $6.00$120.00 per share over a period of 30 consecutive trading days prior to December 31, 2022 or if a change in control occurs during the performance period at the specified stock price (and on a proportional basis for a change in control price between the grant date price and the specified stock price) ("Market-based Performance Share Units"). We determined these awards are subject to a market condition, and therefore we used a Monte Carlo simulation to calculate the grant date fair value of the awards and the related derived service period over which we will recognizerecognized the expense. The key inputs used in the Monte Carlo simulation were the risk-free rate, our volatility of 49.8% and our cost of equity of 12.8%.

14. REVENUE RECOGNITION
We recognize revenue when we satisfy a performance obligation by transferring a promised good or service to a customer. Substantially all of our performance obligations are satisfied at a point in time rather than over time. We offer goods and services through our online marketplaces in three primary categories: Local, Goods and Travel. Refer toSee Note 20,19, Segment Information, for revenue summarized by reportable segment and category.
ProductContract Balances
Our deferred revenue relates to product sales and gift card revenue. Revenue for product sales is earned from direct sales of merchandise inventoryrecognized as the products are delivered to customers, throughgenerally within two weeks following the balance sheet date, while revenue for gift cards is recognized upon customer redemption. Our deferred revenue was $3.5 million as of December 31, 2021. As of December 31, 2020 and 2019, our Goods categorydeferred revenue was $11.2 million and includes any related shipping fees. Service revenue primarily represents$18.0 million, all of which was recognized during the net commissions earned from selling goods or services on behalf of third-party merchants. Those transactions generally involve a customer's purchase of a voucher through one of our online marketplace that can be redeemed by the customer with a third-party merchant for goods or services (or for discounts on goods or services). To a lesser extent, service revenue also includes commissions earned when customers make purchases with retailers using digital coupons accessed through our websitesyears ended December 31, 2021 and mobile applications.
In connection with most of our product and service revenue transactions, we collect cash from credit card payment processors shortly after a sale occurs. For transactions in which we earn commissions when customers make purchases with retailers using digital coupons accessed through our websites and mobile applications, we generally collect payment from affiliate networks on terms ranging from 30 to 150 days.

In September 2015, we commenced a restructuring plan relating primarily to workforce reductions in our international operations. We have also undertaken workforce reductions in our North America segment. In addition to workforce reductions in our ongoing markets, we ceased operations in 17 countries within our International segment as part of the restructuring plan between September 2015 and March 2016. Those country exits, which generally comprised our smallest international markets, resulted from a series of separate decisions made at different times

Variable Consideration for Unredeemed Vouchers
during that periodDuring the year ended December 31, 2021, we recognized $31.4 million of variable consideration from unredeemed vouchers that were notsold in a prior year. We have observed redemption rates lower than our historical estimates for vouchers sold at the onset of the COVID-19 pandemic, the substantial majority of which reached expiration during the year ended December 31, 2021. Although redemption rates for vouchers sold in more recent periods have improved, the impact of COVID-19 on redemption behavior in future periods is still uncertain. When actual redemptions differ from our estimates, the effects could be material to the consolidated financial statements.

In April 2020, the Board approved a multi-phase restructuring plan related to our previously announced strategic shift and as part of an overall strategic shift.the cost cutting measures implemented in response to the impact of COVID-19 on our business. We have incurred total pretax charges of $106.7 million since the inception of the restructuring plan. Our actions under the plan are substantially complete and we expect any future charges or credits will be from changes in estimates. Our restructuring plan included workforce reductions of approximately 1,600 positions globally, the exit or discontinuation of the use of certain leases and other assets, impairments of our right-of-use and other long-lived assets, and the exit of our operations in New Zealand and Japan. In the first quarter 2021, we substantially liquidated our subsidiary in Japan and reclassified $32.3 million of cumulative foreign currency translation gains into earnings, which is presented in Other income (expense), net on the consolidated statements of operations for the year ended December 31, 2021. Costs incurred related to the restructuring plan are classified as Restructuring and related charges on the consolidated statements of operations. The actions under our restructuring plan were completed as of September 30, 2017 and substantially all of the cash payments for actions under that plan were disbursed as of December 31, 2018.
During the third quarter of 2017, we reached a decision to cease most of our food delivery operations and entered into a long-term commercial agreement with a subsidiary of Grubhub that will allow us to provide customers with the ability to order food delivery through our websites and mobile applications in the United States from Grubhub's network of restaurant merchants. See Note 6, Goodwill and Other Intangible Assets, for additional information. For the year ended December 31, 2017, our restructuring costs associated with ceasing those food delivery operations were $2.6 million, primarily related to employee severance. Additionally, we entered into an agreement to sell customer lists and other intangible assets in certain food delivery markets to Grubhub.
We incurred cumulative costs for employee severance and benefits and other exit costs of $80.1 million under the plan since its inception in September 2015. In addition to those costs, we incurred cumulative long-lived asset impairment charges of $7.5 million resulting from our restructuring activities. There were no asset impairments as a result of restructuring activities during the years ended December 31, 2019, 2018 and 2017. The amounts presented in Restructuring charges for the years ended December 31, 2019 and 2018 reflect changes in estimates related to prior actions.
The following tables summarize costs incurred by segment related to the restructuring plan for the years ended December 31, 2019, 20182021 and 20172020 (in thousands):

As a part of our restructuring plan, we terminated or modified several of our leases. In other cases we vacated our leased facilities, and some of those facilities are being actively marketed for sublease or we are in negotiations with the landlord to potentially terminate or modify those leases. For the year ended December 31, 2021, we recognized $5.5 million and $2.2 million of long-lived asset impairment in our North America and International segments due to actions taken under our restructuring plan. For the year ended December 31, 2020, we recognized $18.1 million and $3.5 million of long-lived asset impairment in our North America and International segments due to actions taken under our restructuring plan. See Note 3, COVID-19 Pandemic, Note 4, Property, Equipment and Software, Net and Note 9, Leases for additional information. Rent expense, including amortization of the right-of-use asset and accretion of the operating lease liability, sublease income, termination and modification gains and losses, and other variable lease costs related to the leased facilities vacated as part of our restructuring plan are presented within Restructuring and related charges in the consolidated statements of operations. The current and non-current liabilities associated with these leases continue to be presented within Other current liabilities and Operating lease obligations in the consolidated balance sheets.

(1)Tax rates in foreign jurisdictions were generally lower than the U.S. federal statutory rate through December 31, 2019. This results in an adverse impact to the provision (benefit) for income taxes in this rate reconciliation for the years ended December 31, 2019, 2018 and 2017 prior to the impact of valuation allowances, due to the net pretax losses from continuing operations in certain foreign jurisdictions with lower tax rates.
(2)The effect of income tax rate changes on deferred items for the year ended December 31, 2017 is primarily related to the U.S. tax reform legislation that was signed into law on December 22, 2017, which included a reduction of the U.S. Federal income tax rate to 21 percent. That rate reduction did not impact our provision for income taxes for the year ended December 31, 2017 due to the valuation allowance against our U.S. net deferred tax assets.
(3)During the year ended December 31, 2019, we updated our net operating losses to remove deferred tax assets that could never be utilized due to IRC Section 382 limitations. The amount of State income taxes, net of federal benefits, and state tax credits, Change in valuation allowances and Non-deductible or non-taxable items for the year ended December 31, 2018 have been updated from $2.0 million, $3.8 million and $7.3 million previously reported to reflect that change.

(1)During the year ended December 31, 2019, we updated our net operating losses to remove deferred tax assets that could never be utilized due to IRC Section 382 limitations. The amount of Net operating loss and tax credit carryforwards and Valuation allowances for the year ended December 31, 2018 have been updated from $206.3 million and $228.0 million previously reported to reflect that change.
We have incurred significant losses in recent periods and had an accumulated deficit of $1,032.9 million as of December 31, 2019. As a result, we maintained valuation allowances against our domesticrecognize deferred tax assets and substantially all of our foreign deferred tax assets as of December 31, 2019 and 2018 to reduce their carrying values to amountsthe extent that arethey will be realizable either through future reversals of existing taxable temporary differences, or through taxable income in carryback years for the applicable jurisdictions.jurisdictions or based on projections of future income for those jurisdictions that have achieved sustained profitability. In evaluating the need for a valuation allowance, management considers both positive and negative evidence that could affect its view of the future realization of deferred tax assets and places greater weight on recent and objectively verifiable current information. As of December 31, 2021, we have demonstrated sustained profitability and are forecasting pre-tax earnings in the U.S., which have been considered to be sources of positive evidence. In analyzing all available evidence, management determined there is sufficient positive evidence outweighing negative evidence to conclude that it is more likely than not that a portion of the U.S. deferred tax assets is realizable. As a result, we released $57.7 million of the valuation allowance against our federal and state deferred tax assets, resulting in a $50.3 million reduction to expense, and a $7.4 million adjustment to equity. We continue to maintain a valuation allowance in the U.S. against capital losses, deferred tax assets that will convert into capital losses upon reversal, and state credits that we are not expecting to be able to realize, and substantially all of our foreign deferred tax assets.
We had $48.1$22.0 million of federal net operating loss carryforwards as of December 31, 20192021 which will begin expiring in 2027. We had $214.7$61.7 million of state net operating loss carryforwards as of December 31, 2019,2021, which beganwill begin expiring in the current period.2023. As of December 31, 2019,2021, we had $343.0$489.8 million of foreign net operating loss carryforwards, a significant portion of which carry forward for an indefinite period.
We are subject to taxation in the United States, state jurisdictions and foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording the related income tax assets and liabilities. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not criterion, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

The total amount of unrecognized tax benefits as of December 31, 2019, 20182021, 2020 and 20172019 that, if recognized, would affect the effective tax rate are $25.1$18.7 million, $33.3$19.9 million and $37.6$25.1 million.
We recognized $1.4$1.0 million, $1.6$1.0 million and $0.2$1.4 million of interest and penalties within Provision (benefit) for income taxes on our consolidated statements of operations for the years ended December 31, 2019, 20182021, 2020 and 2017.2019. Total accrued interest and penalties as of December 31, 20192021 and 20182020 were $4.9$5.6 million and $5.4$4.9 million, and are included within Other non-current liabilities in our consolidated balance sheets.
We are currently under IRS audit for the 2015, 2016 and 2017 tax years. Additionally, we are currently under audit by several foreign jurisdictions. It is likely that the examination phase of some of those audits will conclude in the next 12 months. There are many factors, including factors outside of our control, which influence the progress and completion of those audits. We recognized income tax benefits of $12.3$3.2 million, $7.9$8.9 million and $3.0$12.3 million for the years ended December 31, 2019, 20182021, 2020 and 2017,2019, as a result of new information that impacted our estimates of the amounts that are more-likely-thanmore likely than not of being realized upon settlement of the related tax positions and due to expirations of the applicable statutes of limitations. We are subject to claims for tax assessments by foreign jurisdictions, including a proposed assessment for $113.3$118.5 million, inclusive of estimated incremental interest from the original assessment. We believe that the assessment, which primarily relates to transfer pricing on transactions occurring in 2011, is without merit and we intend to vigorously defend ourselves in that matter. In addition to any potential increases in our liabilities for uncertain tax positions from the ultimate resolution of that assessment, we believe that it is reasonably possible that reductions of up to $20.4$26.2 million in unrecognized tax benefits may occur within the 12 months following December 31, 20192021 upon closing of income tax audits or the expiration of applicable statutes of limitations.
In general, it is our practice and intention to reinvest the earnings of our non-U.S. subsidiaries in those operations. Additionally, while we did not incur the deemed repatriation tax, an actual repatriation from our non-U.S. subsidiaries could be subject to foreign and U.S. state income taxes. Aside from limited exceptions for which the related deferred tax liabilities recognized as of December 31, 20192021 and 20182020 are immaterial, we do not intend to distribute earnings of foreign subsidiaries for which we have an excess of the financial reporting basis over the tax basis of our investments and therefore have not recorded any deferred taxes related to such amounts. The actual tax cost resulting from a distribution would depend on income tax laws and circumstances at the time of distribution. Determination of the amount of unrecognized deferred tax liability related to the excess of the financial reporting basis over the tax basis of our foreign subsidiaries is not practical due to the complexities associated with the calculation.
Groupon uses a cost-sharing arrangement under which controlled members agree to share the costs and risks of developing intangible properties in accordance with their reasonably anticipated share of benefits from the intangibles. On July 24, 2018, the Ninth Circuit Court of Appeals issued an opinion in Altera Corp. v. Commissioner requiring related parties in an intercompany cost-sharing arrangement to share expenses related to stock-based compensation. This opinion reversed an earlier decision of the United States Tax Court. On August 7, 2018, the Ninth Circuit Court of Appeals withdrew its July 24, 2018 opinion. On June 7, 2019, the United States Court of Appeals for the Ninth Circuit reversed the Tax Court decision and ruled that stock-based compensation must be included in the shared pool of expenses. The ruling, which was outside the Circuit Court of Appeals for Groupon, did not have a material impact on our provision for income taxes for the year ended December 31, 2019.

17.16. VARIABLE INTEREST ENTITY
Variable interest entities ("VIEs") are entities that have either a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest (i.e., the ability to make significant decisions through voting rights and the right to receive the expected residual returns of the entity or the obligation to absorb the expected losses of the entity). A variable interest holder that has both (a) the power to direct the activities of the VIE that most significantly impact its economic performance and (b) either an obligation to absorb losses or a right to receive benefits that could potentially be significant to the VIE is referred to as the primary beneficiary and must consolidate the VIE.
We have an arrangement with a strategic partner to offer deals related to live events, and a limited liability company ("LLC") has been established to administer that arrangement. Groupon and the strategic partner each own 50% of the outstanding LLC interests, and income and cash flows of the LLC are allocated based on agreed upon percentages specified in the related LLC agreement.
Our obligations associated with our interests in the LLC are primarily administering transactions, contributing intellectual property, identifying deals and promoting the sale of deal offerings, coordinating the distribution of deal offerings and providing the record keeping.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Under the LLC agreement, as amended, the LLC shall be dissolved upon the occurrence of any of the following events: (1) either party becoming a majority owner; (2) July 2022; (3) certain elections of Groupon or the strategic partner based on the operational performance of the LLC or other changes to certain terms in the agreement; (4) election of either Groupon or the strategic partner in the event of bankruptcy by the other party; (5) sale of the LLC; or (6) a court's dissolution of the LLC.
We have determined that the LLC is a VIE and that we are its primary beneficiary. We consolidate the LLC because we have the power to direct the activities of the LLC that most significantly impact the LLC's economic performance. In particular, we identify and promote the deal offerings, provide all of the operational and back office support, present the LLC's deal offerings via our websites and mobile applications and provide the editorial resources that create the verbiage for the related deal offers.
18.17. FAIR VALUE MEASUREMENTS
Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability.
To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs in valuation methodologies used to measure fair value:
Level 1 - Measurements that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2 - Measurements that include other inputs that are directly or indirectly observable in the marketplace.
Level 3 - Measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. These fair value measurements require significant judgment.
In determining fair value, we use various valuation approaches within the fair value measurement framework. The valuation methodologies used for our assets and liabilities measured at fair value and their classification in the valuation hierarchy are summarized below:
Fair value option investments and available-for-sale securities. To determine the fair value of ourWe have fair value option investments each period,and available-for-sale securities that we first estimatemeasure using the fair value of each entity in its entirety. We primarily use the discounted cash flow method, which is an income approach, to estimate the fair value of the entities. The key inputs to determining fair values under that approach are cash flow forecasts and discount rates. We also use a market approach valuation technique, which is based on market multiples of guideline companies, to determine the fair value of each entity. The discounted cash flow and market multiple valuations are then

evaluated and weighted to determine the amount that is most representative of the fair value of each entity. Once we determine the fair value of each entity, we then determine the fair value of our specific investments in those entities. The entities have complex capital structures, so we apply an option-pricing model that considers the liquidation preferences of each entity's respective classes of ownership interests to determine the fair value of our investment in each entity.
We also have investments in redeemable preferred shares and had investments in convertible debt securities issued by nonpublic entities.approach. We measure the fair value of those available-for-sale securities using the discounted cash flow method.
We have classified our fair value optionthese investments and our investments in available-for-sale securities as Level 3 due to the lack of observable market data over fair value inputs such as cash flow projections and discount rates. Increases in projected cash flows and decreases in discount rates contribute to increases in the estimated fair values of the fair value option investments and available-for-sale securities, whereas decreases in projected cash flows and increases in discount rates contribute to decreases in their fair values.
Contingent consideration. We are subject toDuring the first quarter 2021, we settled a contingent consideration arrangement to transfer a maximum payout in cash of $2.5 million to the former owners of a business previously acquired on April 30,in 2018. See Note 4, Business Combinations, for further discussion of that acquisition. Additionally, we had contingent obligations in prior periods to transfer cash to the former owners of a previous business acquisition if specified financial results were met (i.e. an earnout).
Liabilities for contingent consideration are measured at fair value each reporting period, with the acquisition-date fair value included as part of the consideration transferred in the related business combination and subsequent changes in fair value recorded in earnings within Selling, general and administrative expense on the consolidated statements of operations.
We use anthe income approach to value contingent consideration obligations based on the present value of probability-weighted future cash flows.financial performance. We classify thehave previously classified our contingent consideration liabilities as Level 3 due to the lack of relevant observable market data over fair value inputs such as probability-weighting of payment outcomes.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Certain assets and liabilities are measured at fair value on a nonrecurring basis, including assets that are written down to fair value as a result of an impairment or increased due to an observable price change in an orderly transaction.
During the year ended December 31, 2021, we adjusted the carrying value of an other equity investment, which resulted in an unrealized gain of $89.1 million, and sold shares in 2 other equity investments for a gain of $6.4 million. For the year ended December 31, 2020, we recognized a $6.7 million impairment related to an other equity method investment. For the year ended December 31, 2019, we adjusted the carrying value of an other equity investment, for observable price changes in an orderly transaction, which resulted in an unrealized gain of $51.4 million.
For the year ended December 31, 2018, we recorded a $4.6 million impairment of an other equity investment. To determine the fair value of the investment, we considered the financial condition of the investee and applied a market approach. We have classified the fair value measurement of that other equity investment as Level 3 because it involves significant unobservable inputs. Refer to See Note 7,6, Investments, for additional information.

We recognized $7.7 million in non-cash impairment charges related to right-of-use assets - operating leases and leasehold improvements during the year ended December 31, 2021, which is included in Restructuring and related charges on our consolidated statements of operations. We recognized $109.5 million in non-cash impairment charges related to goodwill and $44.0 million in non-cash impairment charges related to long-lived assets during the year ended December 31, 2020, of which $21.6 million is included in Restructuring and related charges on our consolidated statements of operations. See Note 4, Property, Equipment and Software, Net, Note 5, Goodwill and Other Intangible Assets, Note 9, Leases and Note 14, Restructuring and Related Charges, for additional information.
We classified the fair value of the Atairos Notes and 2026 Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the respective note and our cost of debt. The estimated fair value of the 2026 Notes, that were issued in March and April 2021, was $183.3 million as of December 31, 2021 and the Atairos Notes, that were repurchased in May 2021, was $263.3 million as of December 31, 2020, both of which were determined using a lattice model. See Note 8, Financing Arrangements, for additional information.

We did not record any significant nonrecurring fair value measurements after initial recognition for the year ended December 31, 2017.
Estimated Fair Value of Financial Assets and Liabilities Not Measured at Fair Value
Our financial instruments not carried at fair value consist primarily of accounts receivable, restricted cash, short-term borrowings, accounts payable, accrued merchant and supplier payables and accrued expenses. The carrying values of those assets and liabilities approximate their respective fair values as of December 31, 20192021 and 20182020 due to their short-term nature.
19.18. INCOME (LOSS) PER SHARE
Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities include stock options, restricted stock units, performance share units, performance bonus awards, ESPP shares, warrants, and convertible senior notes.notes and capped call transactions. If dilutive, those potentially dilutive securities are reflected in diluted net income (loss) per share using the treasury stock method, except for the convertible senior notes, which are subject to the if-converted method.

The segment information reported in the tables below reflects the operating results that are regularly reviewed by our chief operating decision maker to assess performance and make resource allocation decisions. Our operations are organized into 2 segments: North America and International. Our measure of segment profitability is contribution profit, defined as gross profit less marketing expense, which is consistent with how management reviews the operating results of the segments. Contribution profit measures the amount of marketing investment needed to generate gross profit. Other operating expenses are excluded from contribution profit as management does not review those expenses by segment.

21. RELATED PARTY TRANSACTION
On December 28, 2016, we entered into a sublease for portions of our office space at 600 West Chicago to Uptake, Inc. ("Uptake"), a Lightbank LLC ("Lightbank") portfolio company. Eric Lefkofsky, our co-founder and Chairman of the Board, is a co-founder and owns a significant equity interest in Lightbank. The sublease was a market rate transaction on terms that we believe are no less favorable than would have been reached with an unrelated third party. The sublease extends through January 31, 2026 and sublease rentals over the entire term total approximately $18.2 million. Pursuant to our related party transaction policy, our Audit Committee approved the sublease. We recognized income from the sublease of $2.1 million, $2.1 million and $1.9 million for the years ended December 31, 2019, 2018 and 2017.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

ITEM 9A. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Interim Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K.
Based on this evaluation, our management concluded that, as of December 31, 2019,2021, our disclosure controls and procedures are 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 the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Interim Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the Exchange Act. Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Our internal control over financial reporting includes policies and procedures that provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2019.2021. Management reviewed the results of its assessment with our Audit Committee. The effectiveness of our internal control over financial reporting as of December 31, 20192021 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in its report which is included below.
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 quarter ended December 31, 20192021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. As a result of the COVID-19 pandemic, a majority of our employees have been working remotely. We have not identified any material changes to our internal controls over financial reporting as a result of COVID-19 or related changes to our working environment. We are continually monitoring and assessing the impact the COVID-19 pandemic and related restrictions have on our own internal controls to minimize the effect on their design and operating effectiveness.
Limitations on Effectiveness of Controls and Procedures
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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the stockholders and the Board of Directors of Groupon, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Groupon, Inc. and subsidiaries (the “Company”) as of December 31, 2019,2021, based on criteria established in Internal Control - Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019,2021, based on criteria established in Internal Control - Control—Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2019,2021, of the Company and our report dated February 18, 2020,28, 2022, expressed an unqualified opinion on those financial statements and included explanatory paragraphs regarding the Company’s adoption of ASC Topic 842, Leases, and ASC Topic 606, Revenue from Contracts with Customers.statements.
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'sManagement’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.

(1)For the years ended December 31, 2021, 2020 and 2019, Net Increase (Decrease) to Expense includes foreign currency translation gains (losses) of $(8.9) million, $10.2 million and $(1.5) million.
(1)The amount charged to expense related to the income tax valuation allowance for the year ended December 31, 2017 reflects a $46.5 million expense from discontinued operations, partially offset by a $36.1 million benefit from continuing operations. The $46.5 million discontinued operations expense reflects the valuation allowance recognized against loss carryforwards relating to tax losses on the stock of subsidiaries that were divested in 2017.
(2)During the year ended December 31, 2019, we updated our net operating losses to remove deferred tax assets that could never be utilized due to IRC Section 382 limitations. The amount of Net Increase (Decrease) to Expense, Acquisitions and Other and Balance at End of Year for the year ended December 31, 2018 have been updated from $3.8 million, $14.5 million and $228.0 million previously reported to reflect that change.
All other schedules have been omitted because they are either inapplicable or the required information has been provided in the consolidated financial statements or in the notes thereto.
