Our services are typically distributed to our clients under subscription-based license agreements that typically renew automatically, a majority of which have a term of at least one year. Upon renewal, many of the subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations. To encourage clients to use our services regularly, we generally charge a fixed monthly amount for our subscription-based services rather than charging fees based on actual systemplatform usage or number of paid clicks. Depending on the type of service, contract rates are generally based on the number of sites, number of users, organization size, the client's business focus, geography,the client's geographic location, the number and types of services to which a client subscribes, the number of properties a client advertises and the prominence and placement of a client's advertised properties in the search results. Our subscription clients generally pay contract fees on a monthly basis, but in some cases may pay us on a quarterly or annual basis. Our transaction-based services primarily consist of auction fees from our Ten-X online auction platform for commercial real estate, which are generally calculated as a percentage of the final sales price for the commercial real estate property sold and recognized as revenue upon the successful closure of an auction. We generally see higher sales of Apartments.com listing services during the peak summer rental season and higher CoStar sales towards the end of the year, however sales fluctuate from year-to-year and revenue is not generally seasonal because our services are typically sold on a subscription basis.


Expansion and Growth


Acquisitions


We have continually expanded and continue to expand the geographical coverage and depth of our existing information services and developed new information, analytics and online marketplace services. In addition to organic growth, we have grown our business through strategic acquisitions. On February 21, 2018,May 24, 2021, we completed the acquisition of ForRent, a division of Dominion Enterprises. ForRent’s primary service is digital advertising through a network of four multifamily websites, which includes ForRent.com, AFTER55.com, CorporateHousing.com and ForRentUniversity.com.acquired Homes.com. On October 12, 2018,1, 2021, we acquired Realla Ltd.,Comreal Info, the owner and operator of a commercial property listings and data management platform in the U.K., including a free-to-list search engine for commercial property listings. On November 8, 2018, we acquired Cozy,BureauxLocaux, a leading providercommercial real estate digital marketplace in France. We continue to integrate our recent acquisitions and the U.S.services they offer into our CoStar network. See Notes 5 and 9 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of online rental solutions that provides a broad spectrumthis Annual Report on Form 10-K for further discussion of these acquisitions.


of services to both landlords and tenants, including property listings, rent estimates, rental applications, tenant screening, online rent payments, and expense tracking.


Development, Investments and Expansion


We plan to continue to invest in our business and our services, evaluate strategic growth opportunities and pursue our key priorities as described below in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, while we continue to monitor the economic impacts of the COVID-19 pandemic and manage our response. We are committed to supporting, improving and enhancing our information, analytics and online marketplace solutions, including expanding and improving our offerings for property owners, property managers, brokers, agents, buyers, commercial tenants and renters.residential renters and homebuyers. We expect to continue our software development efforts to improve existing services, introduce new services, integrate and cross-sell services and expand and develop supporting technologies for our research, sales and marketing organizations. We reevaluate our priorities on a regular basis and may reevaluate our priorities as the COVID-19 pandemic continues to evolve.


We evaluate potential changes to our service offerings from time to time in order to better align the services we offer with customers’ needs. Further, in some cases, when integrating and coordinating our services and assessing industry and client needs, we may decide to combine, shift focus from, de-emphasize, phase out, or eliminate a service that, among other things, overlaps or is redundant with other services we offer. In the event that we eliminate or phase out particular service offerings, we may experience reduced revenues and earnings. The decision to eliminate or phase out a service offering may also ultimately
6


result in increased revenues and earnings from sales of other services we offer in lieu of the eliminated or phased out services. However, we cannot predict with certainty the amount or timing of any reductions in revenues and earnings or subsequent increases in revenues and earnings, if any, resulting from the elimination or phasing out of any service offering.

In 2018, we completed the integration of ForRent, including the ForRent sales team and the services offered by ForRent and have worked to maintain ForRent's relationships with its customers that existed prior to the acquisition. ForRent.com is expected to remain a distinct, complementary brand to Apartments.com, giving property managers and owners more exposure for their listings.

We are also continuing to develop new, and improve existing, online rental property service offerings for the apartments industry. We plan to integrate the Cozy suite technology into the Aparments.com platform, creating an integrated online rental solution. In particular, we expect to implement the ability for renters to apply for leases online, for landlords to run tenant credit and background checks online and, eventually, for landlords and tenants to generate and enter into leases and to make and process payments online.

We are expanding the geographic reach of our services. We plan to integrate Realla with our CoStar UK operations, including development of a single point of data entry to allow our clients to display their commercial real estate listings through the CoStar Suite service offering and to make them visible to prospective tenants and investors through Realla’s marketing portal.


We believe that our integration efforts and continued investments in our services, including acquisitions and expansion of our existing service offerings, have created a platform for long-term revenue growth. We expect these investments to result in further penetration of our subscription-based services and the successful cross-selling of our services to customers in existing markets.


We have invested in the expansion and development of our field sales force to support the growth and expansion of our company and our service offerings. Weoffering and plan to continue to invest in, evaluate and strategically position our sales force as the Company continueswe continue to develop and grow. We alsoIn addition, we continue to invest in marketing our services, as well as in our research operations to support continued growth of our information and analytics offerings to meet the growing content needs of our clients. We plan to continue to utilize multi-channel marketing campaigns and to work to determine the optimal level of marketing investments for our services for future periods. While we believe the investments we make in our business create a platform for growth, those investments may reduce our profitability and adversely affect our near-term financial position. We introduced new enhancements on the CoStar homepage, including a Listing Manager feature that we believe will increase the quantity and quality of the listing information available by enabling brokers and other industry participants to load information directly into the integrated system.  Over time, we expect this feature will reduce the time and costs associated with researching and maintaining our comprehensive database of commercial real estate information.


Industry Overview


The market for commercial real estate information and analysis is vast based on the variety, volume and value of transactions related to commercial real estate. Each transaction has multiple participants and multiple information requirements and in order to facilitate transactions, industry participants must have extensive, accurate and current information and analysis. Members of the commercial real estate and related business community require daily access to current data such as space availability, properties for sale,for-sale, rental units available, rental rates, vacancy rates, tenant movements, sales comparables, supply, new construction, absorption rates and other important market developments to carry out their businesses effectively. Market research (including historical and forecast conditions) and applied analytics are instrumental to the success of commercial real estate industry participants operating in the current economic environment.participants. There is a strong need for an efficient marketplace, where commercial


real estate professionals can exchange information, evaluate opportunities using standardized data and interpretive analyses and interact with each other on a continuous basis.


A large number of parties involved in the commercial and residential real estate and the related business community make use of the services we provide in order to obtain information they need to conduct their businesses, including:
Sales and leasing brokersGovernment agencies
Property ownersMortgage-backed security issuers
Property managersAppraisers
Design and construction professionalsPension fund managers
Real estate developersReporters
Real estate investment trust managersTenant vendors
Investment and commercial bankersBuilding services vendors
CommercialMortgage bankersCommunications providers
Mortgage bankersbrokersInsurance companies’ managers
Mortgage brokersRetailersInstitutional advisors
RetailersHospitality ownersInvestors and asset managers
Real estate agents

The commercial real estate and related business community historically operated in an inefficient marketplace because of the fragmented approach to gathering and exchanging information within the marketplace. Various organizations, including hundreds of brokerage firms, directory publishers and local research companies, collected data on specific markets and developed software to analyze the information they independently gathered. This highly fragmented methodology resulted in duplication of effortefforts in the collection and analysis of information, excessive internal cost and the creation of non-standardized data containing varying degrees of accuracy and comprehensiveness, resulting in a formidable information gap.


The creation and maintenance of a standardized information platform for commercial real estate requires infrastructure including a standardized database, accurate and comprehensive research capabilities, experienced analysts, easy to use technology and intensive participant interaction.

The apartment rental advertising industry serves property managers and owners who are tasked with finding renters to occupy vacant apartments, andas well as renters who are searching for their next home. Property managers have several options at their disposal, including their own websites, drive-by and outdoor advertising, traditional classified ads, free online listing services, search engine marketing and internet listings services (“ILS”), like Apartments.com and the network of apartment listing websites we own and operate. Many apartment ILS websites feature only the rental availabilities that larger property owners pay to advertise, resulting in a poor user experience in which the renter’s search criteria return either limited or no results, irrelevant results or stale results that do not represent actual availabilities.


We believe that consumers expect accurate, actionable and comprehensive apartment rental information. Our apartment ILS websites include renter-focused features like the ability to filter search results according to various criteria (e.g., commute time to work); professional images of the properties, including immersive videos and 3-D interactive models; custom neighborhood profiles; and tenant reviews. Our network of apartment listing websites draws on our multifamily database and includes researched and verified information. We proactively gather information on available rentals to improve the accuracy of the listings on our apartment ILS websites, including real time unit-level availability, current pricing and rent specials. We have continually invested in our network to improve the features and services offered to property managers and website users. Recent additions include: dynamic lead forms that provide more information about prospective residents, a reporting suite that provides customers with rent comparables, making rent trends information publicly available, and free digital ad retargeting.retargeting and integrated online rental solutions, including lease applications with tenant credit and background checks. We believe that we have created and maintain easily searchable apartment ILS websites with a comprehensive selection of rentals, information on actual rental availabilities and rents and in-depth data on neighborhoods.neighborhoods, as well as easy to use and actionable tools for the rental process.


We believe that consumers expect accurate, actionable and comprehensive homes for sale information in a platform that allows collaboration between homebuyers and agents. Our residential websites include homebuyer-focused features like the ability to filter search results according to various criteria (e.g., home features, view and lot type), review rankings of nearby schools and tools to educate consumers on the home buying process. We plan to develop original, media rich content of neighborhoods, schools, parks and condominium buildings' amenities and common areas to supplement information in agent listings. We are designing tools to facilitate collaboration between homebuyers and agents.

Licensing agreements with these entities allow us to use a variety of commercial real estate information, including property ownership, tenant information, demographic information, maps, aerial photographs and 3D3-D virtual apartment tours of apartment communities, all of which enhance various CoStarof our services. These license agreements generally grant us a non-exclusive license to use the data and images in the creation and supplementation of our information, analytics and online marketplaces.


Management and Quality Control Systems. Our research processes include automated and non-automated controls to ensure the integrity of the data collection process. A large number of automated data quality tests check for potential errors, including occupancy date conflicts, available square footage greater than building area, typical floor space greater than land area and expired leases. We also monitor changes to critical fields of information to ensure all information is kept in compliance with our standard definitions and methodology. Our non-automated quality control procedures include:

Listings for customers who purchase packages with the highest level of exposure usually appear first in search results and placement of a client's advertised properties inoffer the search results.richest media content and engagement opportunities for tenants searching for space, renters looking for an apartment or investors seeking an opportunity. Our subscription clients generally pay contract fees on a monthly basis, but in some cases may pay us on a quarterly or annual basis.

Our primary marketing methods include: service demonstrations; face-to-face networking; web-based marketing; direct marketing; communication via our corporate website and news services; participation in trade show and industry events; Company-sponsored events; print advertising in trade magazines and other business publications; client referrals; and CoStar TodayTM, LoopNewsTM and other company newsletters distributed via email to our clients and prospects. In 2017, we integrated the CoStar and LoopNet databases in order to enhance CoStar information services as information tools and LoopNet marketplace services as marketing tools. This integration provides clients the ability to enter listings into our Listing Manager tool, and to subsequently update their listings in CoStar and LoopNet simultaneously. To familiarize clients with the integration and benefits of the tool, we provided video tutorials and hosted numerous webinars, in addition to web-based marketing and direct marketing efforts. In 2018, over one hundred thousand commercial real estate professionals and other users successfully made millions of updates to their listings using Listing Manager.

To generate brand awareness and site traffic for the Apartments.com network of rental websites, we utilize a multi-channel marketing campaign featuring television and radio ads, online and digital advertising impressions, social media, public relations, out-of-home and paid search marketing, all of which are reinforced with Search Engine Marketing efforts. We plan to continue to utilize these marketing methods and will continue to work to determine the optimal level of marketing investment for our services for future periods.

Web-based marketing and direct marketing are effective means for us to find prospective clients. Our web-based marketing efforts include search engine optimization, paid advertising with major search engines, social media and display advertising on commercial real estate news and business websites and mobile applications, and our direct marketing efforts include television, radio, out-of-home ads, direct mail, email and telemarketing, and, when applicable, make extensive use of our unique, proprietary database. Once we have identified a prospective client, our most effective sales method is a service demonstration. We use various forms of advertising to build brand identity and reinforce the value and benefits of our services. We also sponsor and attend local association activities and events, including industry-leading events for commercial real estate brokers, owner/investors and retail and financial services institutions, and attend and/or exhibit at industry trade shows and conferences to reinforce our relationships with our core user groups.

News has always been a valuable part of CoStar's core subscription offering. CoStar's news teams report on the latest deals and developments across our markets, keeping subscribers informed and driving higher usage in our core product. In 2018, we hired veteran journalists to guide our news efforts and expanded our team to deliver more robust coverage. We launched a daily newsletter for U.S. subscribers and delivered curated content to our largest markets. We plan to offer even more personalized information in 2019. In 2018, we also upgraded our technology to make our service more relevant for subscribers, giving us the capability to deliver specific news based on their individual preferences.

We believe the ability to customize and personalize news for the user's specific interests should make our news service even more relevant and valuable to subscribers. In addition to encouraging more engagement through logins and time on site, we believe a more robust news operation will also provide more options and formats for advertising to the commercial real estate audience.

We currently offer dozens of webinars each year aimed at helping customers learn more about the commercial real estate industry and how to use our services. The webinars are available both as live presentations and as on-demand programs hosted on our website. On a monthly basis, we issue the CoStar Commercial Repeat Sales Index ("CCRSI"), a comprehensive set of benchmarks that investors and other market participants can use to better understand commercial real estate price movements. CCRSI is produced using our underlying data and is publicly distributed by CoStar through the news media and made available online.

Our sales and marketing efforts have focused and will continue to focus on cross-selling and marketing our services. We continue to develop and cross-sell the services offered by our Apartments.com network of rental websites and the other services we offer, including, but not limited to CoStar Suite. We will also continue to focus on identifying opportunities for customers to benefit from CoStar's Real Estate Manager offering.

As the marketmarkets for information, analytics and online marketplaces develops,develop, additional competitors (including companies which could have greater access to data, financial, product development, technical, analytic or marketing resources than we do) may enter thea market and competition may intensify. For example, a company like Bloomberg L.P. has the resources, and has previously announced an intention, to move into the commercial real estate information business. Further, a company like Google, which has a far-reaching web presence and substantial data aggregation capabilities, could enter the commercial real estate marketing arena. A company like Zillow, which already has a presence in residential real estate and the apartment rentals industry, could use its resources to further expand in the online apartment rentals industry creating greater competition among Internetinternet listing services for the marketing budgets of property managers and property owners. While we believe that we have successfully differentiated ourselves from existing competitors, current or future competitors could materially harm our business. We may also enter markets where incumbent players have greater name recognition and resources, creating challenges as we work to expand.

EmployeesHuman Capital Resources


As of January 31, 2019,2022, we employed 3,7054,742 employees. U.S-based employees represent approximately 89% of the overall employee population, followed by 9% in European, Asia-Pacific and Latin American countries and 2% in Canadian provinces. None of our employees are represented by a labor union. We have experienced no work stoppages. We believe that our employee relations are excellent. InAs is common with many German companies, employees in our German subsidiary, Thomas Daily GmbH, have elected five fellow employees to form a Works Council, which represents our employees at the location andlocation. The Works Council has certain co-determination rights and rights to receive information from us and engage us in discussions under applicable law. BureauxLocaux, in France, has a Social and Economic Committee, which is an employee representative body.


Our human resources and recruiting team works in partnership with business leaders, using a robust to attract a diverse slate of candidates to fill vacancies and contribute to our growth, including our Careers page on our corporate website, employee referral program, social media and digital platforms, direct outreach, partnerships with commercial real estate industry groups and universities and specific partnerships and programs. The development and retention of our employees is critical to our success. To support career development, we offer on-demand and in-person training programs to new hires, managers and leaders. We also offer a mentoring program, which pairs employees seeking mentorship with more experienced colleagues.

To assess employee engagement, we partner with a survey vendor to survey employees annually. Insights and results gathered from the survey are shared with our leadership, managers and employees and help to inform our human resources program strategy each year. We believe that diverse teams deliver better and more innovative solutions. The diversity of thought that comes from different perspectives and backgrounds allows us to deliver cutting edge research and technology solutions that best serve our customers. We have a dedicated Diversity, Equity and Inclusion team that is tasked with developing topical programming, communications and training including, but not limited to, celebrations of various heritage months and oversight of our employee resource groups, which create avenues for mentoring and professional development within these groups as well as education and awareness across the organization.

We provide competitive pay and benefits to attract and retain high quality talent. In addition to base salaries, compensation may include annual bonuses, commissions and equity awards.

Risk Factors

Our revenues and financial position will be adversely affected if we are not able to attract and retain clients. Our success and revenues depend on attracting and retaining subscribers to our information, analytics and online marketplaces.marketplace services. Our subscription-based information, analytics and online marketplacesservices generate the largest portion of our revenues. However,Our revenue may not grow, or could decrease, if we may be unable to attract new clients, and our existing clients may decide not to add, not to renew or to cancel subscription services. In addition, in order to increase our revenue, we must continue tocannot attract new customers, continue to keep our cancellation rate low and continue to sell new services to our existing customers. We may not be able to continue to grow our customer base, keep the cancellation rate for customers and services low or sell new services to existing customers as a result of several factors, including, without limitation: economic pressures; the business failure of a current clientclients; customer decisions that they do not need our services or clients; a decision that customers have no need for our services; a decision to use alternative services; customers’ and potential customers’ pricing and budgetary constraints; consolidation in the real estate and/or financial services industries; data quality; technical problems; competitive pressures; or competitive pressures.devaluation of the local currencies of international customers relative to the U.S. dollar which impairs the purchasing power of such customers. We compete against many other commercial real estate information, analytics and marketing service providers for business, including competitors that offer their services through rapidly changing methods of delivering real estate information.business. If clients cancel services or decide not to renew their subscription agreements and we do not sell new services to our existing clients or attract new clients, then our renewal rate, net new sales and revenues may decline or fail to meet expectations.

We may not be able to successfully develop and introduce new or upgraded information, analytics and online marketplace services that are attractive to our users and advertisers or successfully combine or shift focus from current services with less demand, which could decrease our revenues and our profitability. Our future business and financial success will depend on our ability to continue to anticipate the needs of customers and potential customers and to successfully introduce new and upgraded services, into the marketplace.including services that make our marketplaces useful for users and attractive to advertisers. To be successful, we must be able to quickly adapt to changes in the industry, as well as rapid technological changes by continually enhancing our information, analytics and online marketplace services. As a result, we must continually invest resources in research and development to improve the appeal and comprehensiveness of our services and effectively incorporate new technologies.

Developing new services and upgrades to services, as well as integrating and coordinating current services, imposes heavy burdens on our systems department, product development team, management and researchers. The processes are costly and our efforts to develop, integrate and enhance our services may not be successful. As we continue to combine our operations with those that we have acquired, we must continue to assess the purposes for which various services may be used alone or together, and how we can best address those uses through stand-alone services or combinations of coordinating applications. In addition, successfully launching and selling a new or upgraded service puts additional strain on our sales and marketing resources. If we are unsuccessful in obtaining greater market share or in obtaining widespread adoption of new or upgraded services, we may not be able to offset the expenses associated with the development, launch and marketing of the new or upgraded service, which could have a material adverse effect on our financial results. For example, to generate brand awareness and site traffic for our Apartments.com network of rental websites,marketplaces, we utilize ahave and will continue to invest significant resources in multi-channel marketing campaign.campaigns. If thethese marketing campaign doescampaigns do not continue to increase brand awareness, site traffic and/or revenues, itthe cost of these campaigns could have an adverse effect on our financial results.


If we are unable to develop new or upgraded services or decide to combine, shift focus from, or phase out a service, then our customers may choose a competitive service over ours and our revenues may decline and our profitability may be reduced. If we incur significant costs in developing new or upgraded services or combining and coordinating existing services, if we are not successful in marketing and selling these new services or upgrades, or if our customers fail to accept these new or combined and coordinating services, then there could be a material adverse effect on our results of operations due to a decrease of our revenues and a reduction of our profitability. In addition, as we integrate acquired businesses, we continue to assess which services we believe will best meet the needs of our customers. If we eliminate or phase out a service and are not able to offer and successfully market and sell an alternative service, our revenue may decrease, which could have a material adverse effect on our results of operations.


We may not be able to compete successfully against existing or future competitors in attracting advertisers, which could harm our business, results of operations and financial condition. We may not be able to compete successfully against existing or future competitors in attracting advertisers, which could harm our business, results of operations and financial condition. We compete to attract advertisers. Our competitors may have greater brand recognition or more direct sales personnel than we have and may generate more web traffic than we do, which may provide them with competitive advantages. To compete successfully for advertisers, we must continue to invest resources in developing our advertising platform and proving the effectiveness and relevance of our advertising services. Pressure from competitors seeking to acquire a greater share of our advertisers’ overall marketing budget could adversely affect our pricing and margins, lower our revenue and increase our research and development and marketing expenses. If we are unable to compete successfully against our existing or future competitors, our business, results of operations or financial condition could be adversely affected.

A downturn or consolidation in the commercial real estate industry may decrease customer demand for our services. The commercial real estate market may be adversely impacted by many different factors, including lower than expected job growth or job losses resulting in reduced real estate demand; reduced real estate demand due to increased remote work policies; rising interest rates and slowing transaction volumes due to the impact of the COVID-19 pandemic or otherwise that negatively impact investment returns; excessive speculative new construction in localized markets resulting in increased vacancy rates and diminished rent growth; and unanticipated disasters and other adverse events such as slowing of the growth in the working age population resulting in reduced demand for all types of real estate. A reversal of improvementsdownturn in the commercial real estate industry’smarket, including as a result of a decline in leasing activity and absorption rates or a downturn in the commercial real estate market may affect our ability to generate revenues and may lead to more cancellations by our
18


current or future customers, either of which could cause our revenues or our revenue growth rate to decline and reduce our profitability. A depressed commercial real estate market has a negative impact on our core customer base, which could decrease demand for our information, analytics and online marketplaces. Also, companies in this industry may consolidate, often in order to reduce expenses. Consolidation, or other cost-cutting measures by our customers, may lead to


cancellations of our information, analytics and online marketplace services by our customers, reduce the number of our existing clients, reduce the size of our target market or increase our clients’ bargaining power, all of which could cause our revenues to decline and reduce our profitability. If cancellations, reductions of services and failures to pay increase, and we are unable to offset the resulting decrease in revenues by increasing sales to new or existing customers, our revenues may decline or grow at lower rates.


Negative general economic conditions could increase our expenses and reduce our revenues. Our business and the commercial real estate industry are particularly affected by negative trends in the general economy. The success of our business depends on a number of factors relating to general global, national, regional and local economic conditions, including perceived and actual economic conditions, recessions, inflation, deflation, exchange rates, interest rates, taxation policies, availability of credit, employment levels, and wage and salary levels. Negative general economic conditions could adversely affect our business by reducing our revenues and profitability. If we experience greater cancellations or reductions of services and failures to timely pay, and we do not acquire new clients or sell new services to our existing clients, our revenues may decline and our financial position would be adversely affected.  Adverse national and global economic events, as well as any significant terrorist attack, are likely to have a dampening effect on the economy in general, which could negatively affect our financial performance and our stock price. Further actions or inactions of the U.S. or other major national governments, including "Brexit", may also impact economic conditions, which could result in financial market disruptions or an economic downtown. Market disruptions may also contribute to extreme price and volume fluctuations in the stock market that may affect our stock price for reasons unrelated to our operating performance. In addition, a significant increase in inflation could increase our expenses more rapidly than expected, the effect of which may not be offset by corresponding increases in revenue. Conversely, deflation resulting in a decline of prices could reduce our revenues. In the current economic environment, it is difficult to predict whether we will experience significant inflation or deflation in the near future. A significant increase in either could have an adverse effect on our results of operations. See the risk factor below titled “The economic effects of “Brexit” may affect relationships with existing and future customers and could have an adverse impact on our business and operating results” for further discussion of risks related to Brexit.

If we are unable to hire qualified persons for, or retain and continue to develop, our sales force, or if our sales force is unproductive, our revenues could be adversely affected. In order to support revenues and future revenue growth, we need to continue to develop, train and retain our sales force. Our ability to build and develop a strong sales force may be affected by a number of factors, including: our ability to attract, integrate and motivate sales personnel; our ability to effectively train our sales force; the ability of our sales force to sell an increased number and different types of services; our ability to manage effectively an outbound telesales group; the length of time it takes new sales personnel to become productive; the competition we face from other companies in hiring and retaining sales personnel; our ability to effectively structure our sales force; and our ability to effectively manage a multi-location sales organization, including field sales personnel. If we are unable to hire qualified sales personnel and develop and retain the members of our sales force, including sales force management, or if our sales force is unproductive, our revenues or growth rate could decline and our expenses could increase.

We may not be able to compete successfully against existing or future competitorsface additional challenges in attracting advertisers, which could harmhiring employees in an increasingly competitive job market.

Our internal and external investments may place downward pressure on our business, results of operations and financial condition. We compete to attract advertisers. Our competition for advertisers may have significant brand recognition as well as greater numbers of direct sales personnel thanoperating margins. To increase our revenue growth, we have and may generate more web traffic than we do, which may provide a competitive advantage. To compete successfully for advertisers against future and existing competitors, we must continue to invest resources in developing our advertising platformbusiness, including internal investments in product and provingcontent development to expand the effectivenessbreadth and relevancedepth of services we provide to our advertising services. Pressure from competitors seeking to acquire a greater share of our advertisers’ overall marketing budget could adversely affect our pricingcustomers and margins, lower our revenue, and increase our research and developmentexternal investments in sales and marketing expenses.to generate brand awareness. Our operating margins may experience downward pressure in the short term as a result of these investments. Furthermore, our investments may not produce the expected results. If we are unable to compete successfully againstexecute our existing or future competitors,investment strategy, we may experience decreases in our business, results of operations or financial condition could be adversely affected.revenues and operating margins.


We may be unable to increase awareness of our brands, including CoStar, LoopNet, Apartments.com, BizBuySell, LandsofAmerica, STR, Ten-X, Homes.com and LandsofAmerica,Homesnap, which could adversely affect our business. We rely heavily on our brands, which we believe are key assets of our company. Awareness and differentiation of our brands are important for attracting and expanding the number of users of, and subscribers to, our online marketplaces, such as LoopNet, the Apartments.com network of rental websites, our Homes.com and Homesnap residential marketplaces, CoStar Showcase and the Land.com network of rural lands for sale.for-sale. We expect to continue to invest significantly in sales and marketing in 2022 as we seek to grow the numbers of users of, subscribers to and advertisers on, our marketplaces. Our methods of advertising may not be successful in increasing brand awareness or, ultimately, be cost-effective. If we are unable to maintain or enhance user and advertiser awareness of our brands, or if we are unable to recover our marketing and advertising costs through increased usage of our services and increased advertising on our websites, our business, results of operations and financial condition could be adversely affected.


We rely on InternetIf internet search engines to drive traffic to our websites. If search results do not prominently feature our websites prominently,on the search engine results page, traffic to our websites would decrease and, our business could be adversely affected. Google, Bing, Yahoo! and other Internet search websites drive traffic to our websites, including CoStar.com, the Apartments.com network of rental websites, LoopNet.com,


BizBuySell.com and the Land.com network of land for sale websites. For example, when a user types an apartment building address into an Internet search engine, organic search ranking of our Apartments.com webpages will determine how prominently such webpages are displayed in the search results. However, our ability to maintain high organic search result rankings is not entirely within our control. Our competitors’ search engine optimization, or SEO, efforts may result in their websites receiving a higher search result page ranking than the rankings our websites receive, or Internet search engines could revise their methodologies in a way that would adversely affect our search result rankings, each of which could slow the growth of our user base. Further, search engine providers could align with our competitors, which could adversely affect traffic to our websites. Our websites have experienced fluctuations in search result rankings in the past, and we anticipate similar fluctuations in the future. If we experience a material reduction in the number of users directed to our websites through Internet search engines, our business, results of operations and financial condition could be adversely affected.

Ifif we are unable to maintain or increase traffic to our marketplaces, our business and operating results could be adversely affected. Our ability to generate revenues from our marketplace businessesbusiness depends, in part, on our ability to attract users to our websites. Google, Bing, DuckDuckGo and other internet search engines drive traffic to our websites, including CoStar.com, the Apartments.com network of rental websites, the LoopNet.com network of commercial real estate websites, Ten-X.com, our Homes.com and Homesnap residential marketplaces, the BizBuySell.com network of business for-sale websites and the Land.com network of land for-sale websites. For example, when a user enters in a search query for an apartment building name or address into an internet search engine, the internet search engine’s ranking of our Apartments.com webpages will determine how prominently such webpages are displayed on the search engine results page. Our ability to maintain prominent search result rankings and positioning is not entirely within our control. Our competitors’ Search Engine Optimization (SEO) and Search Engine Marketing (SEM) efforts may result in webpages from their websites receiving higher rankings than the webpages from our websites. Internet search engines could revise their algorithms and methodologies in ways that would adversely affect our search result rankings. Internet search engine providers could form partnerships or enter into other business relationships with our competitors resulting in competitors’ sites receiving higher search result rankings. Internet search engines are increasingly placing alternative search features (such as featured snippets, local map results and other immersive experiences) on the search engine results page above or more prominently than search engine results. If our search result rankings are not prominently displayed, traffic to our websites may decline which could slow the growth of our user base. Our websites have experienced fluctuations in search result rankings in the past and we anticipate similar fluctuations will occur in the future. If we experience a material reduction in the number of users directed to our websites through internet search engines or otherwise fail to maintain or increase traffic to our marketplaces, our ability to acquire additional subscribers or
19


advertisers and deliver leads to and retain existing subscribers and advertisers could be adversely affected. As a result, our business, results of operations and financial condition could be adversely affected. Our marketing expenses may increase in connection with our efforts to maintain or increase traffic to our websites. Our efforts to maintain or generate additional traffic to our marketplaces may not be successful. Even if we are able to attract additional users, increasesIncreases in our operating expenses could negatively impact our operating results if we are unable to generate more revenues through increased sales of subscriptions to our marketplace products. We face competition

Competition could render our services uncompetitive and reduce our profitability. The markets for information systems and services and for online marketplaces in general are highly competitive and rapidly changing. Competition in these markets may increase further if economic conditions or other circumstances cause customer bases and customer spending to attract usersdecrease and service providers to our marketplace websites.compete for fewer customer resources. Our existing and potentialor future competitors, include companies that could devotemay have greater name recognition, larger customer bases, better technology or data, lower prices, easier access to data, greater user traffic or greater financial, technical and otheror marketing resources than we have available to provide services that users might view as superior to our offerings. Any of our future or existing competitorsCompetitors may introduce different solutions that attract users away from our services or provide solutions similar to our ownours that have the advantage of better branding or marketing resources. If we are unableOur competitors may be able to increase trafficundertake more effective marketing campaigns, obtain more data, adopt more aggressive pricing policies, make more attractive offers to potential employees, subscribers, advertisers, distribution partners and content providers or may be able to respond more quickly to new or emerging technologies or changes in user requirements. Increased competition could result in lower revenues and higher expenses, which would reduce our marketplaces, or if we are unable to generate enough additional revenues to offset increases in expenses related to increasing traffic to our marketplaces, our business and operating results could be adversely affected.profitability.


If real estate professionals or other advertisers reduce or cancel their advertising spending with us and we are unable to attract new advertisers, our operating results would be harmed. Our marketplace businesses, including LoopNet, the Apartments.com network of rental websites, CoStar Showcase,our residential brands including Homes.com and Homesnap and the Land.com network of rural lands for sale,for-sale, depend on advertising revenues generated primarily through sales to persons in the real estate industry, including property managers and owners and other advertisers. Our ability to attract and retain advertisers, and ultimately to generate advertising revenue, depends on a number of factors, including:


increasingIncreasing the number of unique visitors to, and users of, our websites and mobile applications;
theThe quantity and quality of the leads that we provide to our advertisers;
theThe success of any marketing and product development efforts directed at attracting additional users and advertisers to our marketplaces;
keepingKeeping pace with changes in technology and with our competitors; and
offeringOffering an attractive return on investment to our advertisers for their advertising dollars spent with us.


Further, with respect to the Apartments.com network of rental websites, our ability to attract and retain advertisers also depends on the current apartment rental market and apartment vacancy rates. If vacancy rates are too high or too low, advertisers may not need to utilize our marketplace services.


Many of the advertisers who advertise on our marketplaces do not have long-term contracts. These advertisers could choose to modify or discontinue their relationships with us with little or no advance notice. In addition, asAs existing subscriptions for advertising expire, we may not be successful in renewing these subscriptions or securing new subscriptions. We may not succeed in retaining existing advertisers’ spending or capturing a greater share of such spending if we are unable to convince advertisers of the effectiveness of our services as compared to alternatives. In addition, future changes to our pricing methodology for advertising services may cause advertisers to reduce or discontinue their advertising with us. If current advertisers reduce or end their advertising spending with us and we are unable to attract new advertisers, our advertising revenues and business, results of operations and financial condition could be adversely affected.


If we do not invest in product development and provide services that are attractive to our users and to our advertisers, our business could be adversely affected. Our success depends on our continued improvements to provide services that make our marketplaces useful for users and attractive to our advertisers. As a result, we must continually invest resources in research and development to improve the appeal and comprehensiveness of our services and effectively incorporate new technologies. If we are unable to provide services that users want to use, then users may become dissatisfied and use competitors’ websites. If we are
20




unable to continue offering innovative services, we may be unable to attract additional users and advertisers or retain our current users and advertisers, which could harm our business, results of operations and financial condition.

If we are not able to successfully identify, finance, integrate and/or manage costs related to acquisitions, our business operations and financial position could be adversely affected. We have expanded our markets and services in part through acquisitions of complementary businesses, services, databases and technologies, and expect to continue to do so in the future. Our acquisition strategy to acquire complementary companies or assets depends on our ability to identify, and the availability of, suitable acquisition candidates. We mayare likely to incur costs in connection with an acquisition,proposed acquisitions, but may ultimately be unable or unwilling to consummate theany particular proposed transaction for various reasons. For example, in 2021, the FTC withheld approval for our proposed acquisition of RentPath, the purchase agreement was subsequently terminated and we incurred a termination fee of $52 million. We are also likely to incur severance costs and other integration costs post-acquisition. Costs in connection with acquisitions and integrations may be higher than expected and could adversely affect our financial condition, results of operation or prospects of the combined business. In addition, acquisitions involve numerous risks, including the abilityrisks that we will not be able to realize or capitalize on synergies created through combinations; managingmanage the integration of personnel and products or services; managingmanage the integration of acquired infrastructure and controls; control potential increases in operating costs; managingmanage geographically remote operations; the diversion ofmaintain management’s attention fromon other business concerns and avoid potential disruptions in ongoing operations during integration; the inherent risks in enteringan acquisition process or integration efforts; successfully enter markets and sectors in which we have either limited or no direct experience;experience, including foreign markets whose practices, regulations or laws may pose increased risk; and the potential loss ofretain key employees, clients or vendors and other business partners of the acquired companies. We may not successfully integrate acquired businesses or assets and may not achieve anticipated benefits of an acquisition, including expected synergies.  For example, we may be unable to fully integrate Cozy technology into the Apartments.com platformHomesnap, Homes.com and BureauxLocaux with CoStar when and as expectedexpected.

We are subject to an FTC consent order, which is publicly available on the FTC's website at http://www.ftc.gov/, that, among other things, requires us to give the FTC advance notice of certain acquisitions.Compliance with this order could prevent us from closing certain acquisitions or fully utilizeadd significant time and realize the benefits of Realla's expertise in capturing listings datacost to facilitate our expansion strategy in other European markets.such acquisitions, ultimately making an acquisition prohibitive or preventing us from realizing its anticipated benefits.

We have incurred severance costs and expect to incur additional costs to integrate prior acquisitions, such as IT integration expenses and costs related to the renegotiation of redundant vendor agreements. Costs in connection with acquisitions and integrations may be higher than expected, and we may also incur unanticipated acquisition-related costs. These costs could adversely affect our financial condition, results of operation or prospects of the combined business.


External factors, such as compliance with laws and regulations and shifting market preferences, may also impact the successful integration of an acquired business. An acquired business could strain our system of internal controls and diminish its effectiveness. Acquisitions could result in dilutive issuances of equity securities, the incurrence of debt one-time write-offs of goodwill and substantial amortization expenses of other intangible assets. We may be unable to obtain financing on favorable terms, or at all, if necessary to finance future acquisitions, making it impossible or more costly to complete future acquisitions. If we are able to obtain financing, the terms may be onerous and restrict our operations. Further, certain acquisitions may be subject to regulatory approval, which can be time consuming and costly to obtain or may be denied, and ifas in the case of RentPath. If regulatory approval is obtained, the terms of any such regulatory approvalsapproval may impose limitations on our ongoing operations or require us to divest assets or lines of business. If regulatory approval is denied, we may incur significant, additional costs payable to an acquisition target as a result of failure to close the transaction. For example, we incurred a termination fee of $52 million in connection with termination of the RentPath purchase agreement. Significant break-up fees incurred in the future may adversely affect our results of operation and financial condition.


As a result of our acquisitions, we had approximately $2.8 billion of goodwill and intangibles as of December 31, 2021.Future acquisitions may increase this amount.If we are required to recognize goodwill and intangibles impairment charges in the future, this would negatively affect our financial results in the periods of such charges, which may reduce our profitability.

Our actual or perceived failure to comply with privacy laws and standards could adversely affect our business, financial condition and results of operations. We depend on information technology networks and systems to process, transmit and store electronic information and to communicate betweenamong our locations around the world and with our clients and vendors. We collect, use and disclose personally identifiable information, including among other thingssuch as names, addresses, phone numbers and email addresses. We collect, store and use biometric data and sensitive or confidential transaction and account information. In addition, weWe also collect personal information from tenants and landlords, including social security numbers, state or federal issued identification numbers, dates of birth,birthdates and financial information and documents, employment information, background checks and credit scores, to facilitate the apartment rental application and payment process between a renter and property manager. As a result, we are subject to a variety of state, national and international laws and regulations that apply to the collection, use, retention, protection, disclosure, transfer and other processing of personal data, including the Fair Credit Reporting Act. LawsAct, the General Data Protection Regulation ("GDPR") and regulations related to privacyCalifornia Consumer Privacy Act ("CCPA"). These laws and data protectionregulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. For example, in 2016, the EU formally adopted the General Data Protection Regulation, or GDPR, which was implemented in all EU member states effective May 25, 2018 and replaced the EU Data Protection Directive. The GDPR introduced new data protection requirements in the EU and imposes substantial fines for breaches of the data protection rules. The GDPR increased our responsibility and liability in relation to personal data that we process. We continueThe CCPA expands the rights of California residents to assess our compliance with GDPR in lightaccess and require deletion of guidance fromtheir personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used. The CCPA also provides for civil penalties for violations, as well as a private right of action for data protection authorities, evolving best practices and evolving regulations and webreaches that may need to put in place additional mechanisms to ensure compliance with the new EUincrease data protection rules.breach litigation. Other states have adopted, or are considering enacting, similar laws. Any failure or alleged failure to comply with the rules arising from the EU Data Protection Directive, the GDPR, and related nationalprivacy or data protection laws of EU member states, could lead to government enforcement actions and significant penalties against us, and

could materially adversely affect our reputation, business, financial condition, cash flows and results of operations. Compliance with any of the foregoing laws and regulations can be costly, and can delay or impede the development of new products. Weproducts, and may incur substantial fines if we violate any laws or regulations relating to the collection or use of personal information.

Our actual or alleged failure to comply with applicable privacy or data security laws, regulations and policies, or to protect personal data, could result in enforcement actions and significant penalties against us, which could result in negative publicity,

Because theThe interpretation and application of many privacy and data protection laws are uncertain, it is possible that theseuncertain. These laws may be interpreted and applied in a manner that is inconsistent with our existing data management practices or the features of our products. If so, in addition to the possibility of negative publicity, fines, lawsuits and other claims and penalties, we could be required to fundamentally change our business activities and practices or modify our products, which could harm our business.


We expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection and information security in the United States and other jurisdictions, and we cannot determine the impact such future laws, regulations and standards may have on our business. Our policies concerning the collection, use and disclosure of personally identifiable information are described on our websites. While we believe that our policies are appropriate and that we are in compliance with our policies, we could be subject to legal claims, government action, harm to our reputation or incur significant remediation costs if we experience a security breach or our practices fail, or are seen as failing, to comply with our policies or with applicable laws concerning personally identifiable information.

Concern regarding our use of the personal information collected on our websites or collected when performing our services could keep prospective customers from subscribing to our services. Industry-wide incidents or incidents with respect to our websites, including misappropriation of third-party information, security breaches or changes in industry standards, regulations or laws, could deter people from using the Internet or our websites to conduct transactions that involve the transmission of confidential information, which could harm our business.

Cyberattacks and security vulnerabilities could result in serious harm to our reputation, business and financial condition. As stated above, our business involves the collection, storage, processing and transmission of customers’ personal data. We also collect, store and process employee personal data. An increasing number of organizations, including large merchants, businesses, technology companies and financial institutions, as well as government institutions, have disclosed breaches of their information security systems, some of which have involved sophisticated and highly targeted attacks, including on their websites, mobile applications and infrastructure.


The techniques used to obtain unauthorized, improper or illegal access to a target's systems, data or customers' data, disable or degrade services, or sabotage systems are constantly evolving and have become increasingly complex and sophisticated, may be difficult to detect quickly and often are not recognized or detected until after they have been launched against a target. We expect that unauthorized parties will continue to attempt to gain access to or disrupt our systems or facilities through various means, including hacking into our systems or facilities or those of our customers or vendors, or attempting to fraudulently induce (for example, through spear phishing attacks or social engineering) our employees, customers, vendors or other users of our systems into disclosing user names, passwords, or other sensitive information, which may in turn be used to access our information technology systems. Numerous and evolving cybersecurity threats, including advanced and persisting cyberattacks, phishing and social engineering schemes, could compromise the confidentiality, availability and integrity of the data in our systems. Our cybersecurity programs and efforts to protect our systems and data, and to prevent, detect and respond to data security incidents, may not prevent these threats or provide security.be effective. Further, the security measures and procedures our customers, vendors and other users of our systems have in place to protect sensitive consumer data and other information may not be successful or sufficient to counter all data breaches, cyberattacks or system failures.


Our information technology and infrastructure may be vulnerable to cyberattacks or security breaches, and third parties may be able to access our customers’ or employees’ personal or proprietary information that is stored on or accessible through those systems. We have experienced from time to time, and may experience in the future, breaches of our security measures due to human error, malfeasance, system errors or vulnerabilities or other irregularities. Actual or perceived breaches of our security could result in any of the following, among other things:things, any of which could adversely affect our business and results of operations:

adversely affect our business and result of operations.




In addition, any cyberattacks or data security breaches affecting companies that we acquire or our customers or vendors (including data center and cloud computing providers) could have similar negative effects on our business. For example, in December 2020, we became aware that one of our vendors providing IT infrastructure management software, SolarWinds Corporation, had been compromised by cyberattacks. As of December 22, 2020, we had implemented the fully patched versions of the SolarWinds software and we took additional measures to block internet connectivity to and from all SolarWinds' Orion servers. Although we have not identified any compromise of our IT systems due to the use of SolarWinds software to date, we continue to monitor our network for any potential impact related to the SolarWinds cyberattack. Similarly, we are regularly exposed to vulnerabilities in widely deployed third-party software that we use in the ordinary course of business, such as the recently identified Log4J vulnerability. While this vulnerability did not have a material adverse effect on our operations, it and similar incidents require us to devote time and resources to remediation on a regular basis. Notwithstanding our efforts, there can be no assurance that vulnerabilities in widely deployed software will not materially harm our business. Any breach of our security measures or the loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential data about us or our customers, including the potential loss or disclosure of such information or data as a result of
22


the SolarWinds cyberattack, could result in litigation and potential liability for us, damage our brand and reputation or otherwise harm our business. The coverage under our insurance policies may not be adequate to reimburse us for losses caused by security breaches.


Technical problems or disruptions that affect either our customers’ ability to access our services, or the software, internal applications, database and network systems underlying our services, could damage our reputation and lead to reduced demand for our information, analytics and online marketplace services, lower revenues and increased costs. Our business, brands and reputation depend upon the satisfactory performance, reliability and availability of our websites, the internet and our service providers. Interruptions in these systems, whether due to system failures, computer viruses, software errors, physical or electronic break-ins, or malicious hacks or attacks on our systems (such as denial of service attacks or use of malware), could affect the security and availability of our services on our mobile applications and our websites and prevent or inhibit users' access to our services. Our operations also depend on our ability to protect our databases, computers and software, telecommunications equipment and facilities against damage from potential dangers such as fire, flood, power loss, security breaches, computer viruses, telecommunications failures, terrorist attacks, acts of war, electronic and physical break-ins, computer viruses, earthquakes and similar events.

In addition, the software, internal applications and systems underlying our services are complex and may not be error-free. We may encounter technical problems when we attempt to enhance our software, internal applications and systems. Our users rely on our services for the conduct of their own businesses. Disruptions in, technical problems with, or reductions in ability to access, our services for any reason could damage our users’ businesses, harm our reputation, result in additional costs or reduce demand for our information, analytics and online marketplace services, any of which could harm our business, results of operations and financial condition.

The majority of the communications, network and computer hardware used to operate our mobile applications and websites are located at facilities in Virginia and California. We do not own or control the operation of certain of these facilities. Our systems and operations are vulnerable to damage or interruption from fire, flood, power loss, security breaches, computer viruses, telecommunications failure, terrorist attacks, acts of war, electronic and physical break-ins, earthquakes and similar events. These risks may be increased with respect to operations housed at facilities we do not own or control. The occurrence of any of the foregoing events could result in damage to our systems and hardware or could cause them to fail completely, and our insurance may not cover such events or may be insufficient to compensate us for losses that may occur.

A failure of our systems at any site could result in reduced functionality for our users, and a total failure of our systems could cause our mobile applications or websites to be inaccessible. Problems faced or caused by our information technology service providers, including content distribution service providers, private network providers, internet providers and third-party web-hosting providers, or with the systems by which they allocate capacity among their customers (as applicable), could adversely affect the experience of our users. Any financial difficulties, such as bankruptcy reorganization, faced by these third-party service providers or any of the service providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict. If our third-party service providers are unable to keep up with our growing needs for capacity, our business could be harmed. In addition, if distribution channels for our mobile applications experience disruptions, such disruptions could adversely affect the ability of users and potential users to access or update our mobile applications, which could harm our business.

Our business interruption insurance may not cover certain events or may be insufficient to compensate us for the potentially significant losses, including the potential harm to the future growth of our business, which may result from interruptions in our service as a result of system failures or malicious attacks. Any errors, defects, disruptions or other performance problems with our services could harm our reputation, business, results of operations and financial condition.

We are planning to undertake a large infrastructure project to build out our campus in Richmond, Virginia, the costs of which could impact our financial condition and results of operations. In December 2021, we announced our plans to expand our research and technology center in Richmond, Virginia. These plans will require significant capital expenditures over the next several years and our business plans may change. Future changes in growth or fluctuations in cash flow may also negatively impact our ability to finance this project. Additionally, actual capital expenditures could vary materially from our projected capital expenditures, which could negatively impact our business, operating results and financial condition. If we are provided with any grants, tax credits, abatements or other incentives related to this expansion effort and do not meet requirements associated with those incentives, we may not be able to benefit from those incentives, which could cause the cost of the project to be significantly more than anticipated or significantly increase our taxes above what we currently expect. We are currently considering financing options and may finance construction with cash on hand. Use of cash on hand to finance construction would reduce the amount of cash available for other corporate uses and could also reduce our ability to meet our
23


scheduled debt service obligations or to meet the covenants required to borrow additional funds under our 2020 Credit Agreement. Any of the foregoing may adversely affect our financial position and results of operations.

Our current or future geographic expansion plans may not result in increased revenues, which may negatively impact our business, results of operations and financial position. Expanding into new markets and increasing the depth of our coverage in existing markets imposes additional burdens on our research, systems development, sales, marketing and general managerial resources. If we are unable to manage our expansion efforts effectively, if our expansion efforts take longer or are more expensive than planned or we are not successful in marketing and selling our services in existing or new markets, our expansion may have a material adverse effect on our financial position by increasing our expenses without increasing our revenues.

Our operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to market cyclicality, each of which could negatively affect our stock price. The real estate market may be influenced by general economic conditions, economic cycles, seasonality and many other factors, which in turn may impact our financial results. The different sectors of the large and fragmented industry, such as office, industrial, retail, multifamily, single family and others, are influenced differently by different factors, and have historically moved through economic cycles with different timing. As such, it is difficult to estimate the potential impact of economic cycles and conditions or seasonality from year-to-year on our overall operating results. We generally see higher sales of Apartments.com listing services during the peak summer rental season and higher CoStar sales towards the end of the year, however sales fluctuate from year-to-year and may fluctuate more widely when there are changes in general economic conditions or the industry, such as changes resulting from the COVID-19 pandemic. In addition, we generally incur greater marketing expenses during the second quarter, which coincides with the peak season for apartment rentals. The timing of widely observed holidays and vacation periods, particularly slowdowns during the end-of-year holiday period, and availability of real estate agents and related service providers during these periods, could significantly affect our quarterly operating results during that period. If we are unable to adequately respond to economic, seasonal or cyclical conditions, our revenues, expenses and operating results may fluctuate from quarter to quarter. Our operating results, revenues and expenses may fluctuate for many reasons, including those described in this paragraph and below and elsewhere in this Annual Report on Form 10-K:

Rates of subscriber adoption and retention;
Timing of our sales conference or significant marketing events;
Changes in our pricing strategy and timing of changes;
The timing and success of new service introductions and enhancements;
The shift of focus from, or phase out of services that overlap or are redundant with other services we offer;
The amount and timing of our expenses and capital expenditures;
The amount and timing of non-cash stock-based charges;
Acquisition-related costs or impairment charges associated with such investments and acquisitions;
Competition;
Changes or consolidation in the real estate industry;
Interest rate fluctuations;
Execution of our expansion and integration plans;
The development of our sales force;
Foreign currency and exchange rate fluctuations;
Inflation; and
Changes in client budgets.

These fluctuations could negatively affect our results of operations during the period in question and/or future periods or cause our stock price to decline. In addition, changes in accounting policies or practices may affect our level of net income. Fluctuations in our financial results, revenues and expenses may cause the market price of our common stock to decline.

Our business depends on retaining and attracting highly capable management and operating personnel. Our success depends in large part on our ability to retain and attract management and operating personnel, including our President and Chief Executive Officer, Andrew Florance, and our other officers and key employees. Our business requires highly skilled technical, sales, management, web product and development, marketing and research personnel, who are in high demand and are often subject to competing offers. To retain and attract key personnel, we use various measures, including employment agreements, awards under a stock incentive plan and incentive bonuses for key employees. These measures may not be enough to retain and attract the personnel we need or to offset the impact on our business of the loss of the services of Mr. Florance or other key officers or employees. We experienced an increase in turnover as we returned nearly all our workforce to the office. We may face additional challenges in retaining employees in an increasingly competitive job market.

24


Changes in tax laws, regulations or fiscal and tax policies or the manner of their interpretation or enforcement could adversely impact our financial performance. New laws or regulations, or changes in existing laws or regulations, or the manner of their interpretation or enforcement, could increase our cost of doing business. In addition, from time to time, U.S. and foreign tax authorities, including state and local governments consider legislation that could increase our effective tax rate. For example, the U.S. Congress has advanced a variety of tax legislation proposals, and while the final form of any legislation is uncertain, the current proposals, if enacted, could have a material effect on our effective tax rate.

Our business and results of operations have been and may be, and our financial condition may be, impacted by the COVID-19 pandemic and such impact could be materially adverse and continue for an unknown period of time. The COVID-19 pandemic has created significant economic volatility, uncertainty and disruption around the world. The extent to which COVID-19 will further impact our business, operations and financial results, including the duration and magnitude of such impact, is uncertain and will depend on numerous rapidly evolving factors that we cannot accurately predict including, among others:

The length and severity of the pandemic, including new variants;
The negative impact on global and regional economies, credit markets and economic activity;
Governmental, business and individual actions taken in response to the pandemic and the impact of those actions on global economic activity;
The impact of business disruptions and reductions in employment levels and the level of consumer confidence in the economy on our clients and the resulting impact on their demand for our services and solutions;
Business consolidations or failures among businesses that we serve;
Our clients’ ability to pay for our services and solutions and our ability to collect payment for services provided; and
The pace and extent of economic recovery following the COVID-19 pandemic, including recovery in the real estate industry in particular.

The demand for office space could decrease significantly as businesses implement hybrid or all work from home arrangements in response to employee desire for more flexibility, which may lead to a downturn in the commercial real estate market. A depressed commercial real estate market would have a negative impact on our core customer base, which could impact our customers’ ability to subscribe and pay for our services and reduce demand for our services. Reduced demand and increased cancellations could cause our revenues or our revenue growth rates to decline and reduce our profitability. As a result of COVID-19 and its impact on global economic conditions, including the real estate industry, towards the end of the first quarter and in the first two months of the second quarter of 2020, we saw an increase in customer requests for cancellations or suspensions, a reduction in new customer sales, failures to pay and delays in payments of amounts owed to us. We may see additional requests as current economic conditions cause customers to reduce expenses and prolong the decision-making time before purchasing third party services, which may lead to fewer of our services being purchased or service cancellations. The extent and duration of any future continued weakening of the economy is unknown, and there can be no assurance that any of the governmental or private sector initiatives designed to strengthen the economy will be successful or available to us and our customers and, if successful, when the benefits will be seen.

COVID-19, and the disruption in global economic conditions stemming from the pandemic, could also precipitate or aggravate the other risk factors discussed in this Report, which could materially adversely affect our business, financial condition and results of operations. Further, the COVID-19 pandemic may also affect our operating and financial results in a manner that is not presently known to us or that we currently do not consider to present significant risks. For additional discussion of the impacts of the COVID-19 pandemic, which could be materially adverse to our operations and financial results, please see "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Impact of the COVID-19 Pandemic" in Item 7 of Part II of this Annual Report on Form 10-K.

We are subject to a number of risks related to acceptance of credit cards and debit cards forand facilitation of other customer payments. We accept payments for our services through credit and debit card transactions. For credit and debit card payments, we pay interchange and other fees, which may increase over time. An increase in those fees may require us to increase the prices we charge and would increase our cost of revenues, either of which could harm our business, financial condition or results of operations..


We depend on processing vendors to complete credit and debit card transactions. If we or our processing vendors fail to maintain adequate systems for the authorizationto authorize and processing ofprocess credit card transactions, one or more of the major credit card companies could disallow our continued use of their payment products. If we are unable to maintain our chargeback rate or refund rates at acceptable levels, our processing vendors may increase our transaction fees or terminate their relationships with us. We could lose customers if we are not able to continue to use payment products of the major credit card companies. In addition, if the systems to authorize and process credit card transactions fail to work properly and, as a result, we do not charge our customers’ credit cards on a timely basis or at all, our business, revenue, results of operations and financial condition could be harmed.

We depend on processing vendors to complete credit and debit card transactions and Automated Clearing House (ACH) payments, both for payments made to us directly for our services and for payments made by renters to landlords using our online leasing services. If we or any one or more of these service providers fail to maintain adequate systems for authorization

and processing credit card payments, it could cause one or more of the major credit card companies to disallow our continued use of their payment products. We could lose customersFurther, if we are not ableor any one or more of these service providers fail to continuemaintain adequate systems for authorization and processing of credit, debit, ACH or similar payments or if any such service provider were to use payment products of the major credit card companies.terminate or modify its relationship with us unexpectedly, our ability to process those customer transactions would be adversely affected, which could decrease sales, discourage customers away from our marketplace services, result in potential legal liability, and harm our business and reputation. In addition, if the systems for the authorization and processing of credit card transactions fail to work properly and, as a result, we do not charge our customers’ credit cards on a timely basis or at all, our business, revenue, results of operations and financial condition could be harmed.


We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be reinterpreted in ways that make it more difficult for us to comply. We are required to comply with payment card industry security standards. Failing to comply with those standards may violate payment card association operating rules, federal and state laws and regulations and the terms of our contracts with payment processors. Any failure to comply also may subject us to fines, penalties, damages and civil liability, and may result in the loss of our ability to accept credit and debit card payments. Further, there is no guarantee that such compliance will prevent illegal or improper use of our payment systems or the theft, loss, or misuse of data pertaining to credit and debit cards, cardholders and transactions.

The payment methods that we offer also subject us to potential fraud and theft by criminals, who are becoming increasingly sophisticated, seeking to obtain unauthorized access to or exploit weaknesses that may exist in the payment systems. If we fail to comply with applicable rules or requirements for the payment methods we accept, or if payment-related data are compromised due to a breach of data, we may be liable for significant costs incurred by payment card issuing banks and other third parties or subject to fines and higher transaction fees, or our ability to accept or facilitate certain types of payments may be impaired. In addition, our customers could lose confidence in certain payment types, which may result in a shift to other payment types or potential changes to our payment systems that may result in higher costs. If we fail to adequately control fraudulent credit cardpayment transactions, we may face civil liability, diminished public perception of our security measures and significantly higher credit card-related costs, each of which could harm our business, results of operations and financial condition.


If we are unable to maintain our chargeback rate or refund rates at acceptable levels, our processing vendors may increase our transaction fees or terminate their relationships with us. Any increases in our credit and debit card fees could harm our results of operations, particularly if we elect not to raise our rates for our services to offset the increase. The termination of our ability to process payments on any major credit or debit card would significantly impair our ability to operate our business.


Technical problems or disruptions that affect either our customers’ ability to access our services, or the software, internal applications, database and network systems underlying our services, could damage our reputation and brands and lead to reduced demand for our information, analytics and online marketplace services, lower revenues and increased costs. Our business, brands and reputation depend upon the satisfactory performance, reliability and availability of our websites, the Internet and our service providers. Interruptions in these systems, whether due to system failures, computer viruses, software errors, physical or electronic break-ins, or malicious hacks or attacks on our systems (such as denial of service attacks), could affect the security and availability of our services on our mobile applications and our websites and prevent or inhibit the ability of users to access our services. Our operations also depend on our ability to protect our databases, computers and software, telecommunications equipment and facilities against damage from potential dangers such as fire, flood, power loss, security breaches, computer viruses, telecommunications failures, terrorist attacks, acts of war, electronic and physical break-ins, computer viruses, earthquakes and similar events. Our users rely on our services when conducting their own businesses. Disruptions in, or reductions in ability to access, our services for whatever reason could damage our users’ businesses, harm our reputation, result in additional costs or result in reduced demand for our information, analytics and online marketplace services, any of which could harm our business, results of operations and financial condition.

In addition, the software, internal applications and systems underlying our services are complex and may not be error-free. Our careful development and testing may not be sufficient to ensure that we will not encounter technical problems when we attempt to enhance our software, internal applications and systems. Any inefficiencies, errors or technical problems with our software, internal applications and systems could reduce the quality of our services or interfere with our customers’ accessRisks related to our information, analyticsdata, intellectual property and online marketplaces, which could reduce the demand for our services, lower our revenues and increase our costs.listings


The majority of the communications, network and computer hardware used to operate our mobile applications and websites are located at facilities in Virginia and California. We do not own or control the operation of certain of these facilities. Our systems and operations are vulnerable to damage or interruption from fire, flood, power loss, security breaches, computer viruses, telecommunications failure, terrorist attacks, acts of war, electronic and physical break-ins, earthquakes and similar events. These risks may be increased with respect to operations housed at facilities we do not own or control. The occurrence of any of the


foregoing events could result in damage to our systems and hardware or could cause them to fail completely, and our insurance may not cover such events or may be insufficient to compensate us for losses that may occur.

A failure of our systems at any site could result in reduced functionality for our users, and a total failure of our systems could cause our mobile applications or websites to be inaccessible. Problems faced or caused by our information technology service providers, including content distribution service providers, private network providers, Internet providers and third-party web-hosting providers, or with the systems by which they allocate capacity among their customers (as applicable), could adversely affect the experience of our users. Any financial difficulties, such as bankruptcy reorganization, faced by these third-party service providers or any of the service providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict. If our third-party service providers are unable to keep up with our growing needs for capacity, our business could be harmed. In addition, if distribution channels for our mobile applications experience disruptions, such disruptions could adversely affect the ability of users and potential users to access or update our mobile applications, which could harm our business.

Our business interruption insurance may not cover certain events or may be insufficient to compensate us for the potentially significant losses, including the potential harm to the future growth of our business, which may result from interruptions in our service as a result of system failures or malicious attacks. Any errors, defects, disruptions or other performance problems with our services could harm our reputation, business, results of operations and financial condition.

If we are not able to obtain and maintain accurate, comprehensive or reliable data, we could experience reduced demand for our information, analytics and online marketplace services. Our success depends on our clients’ confidence in the comprehensiveness, accuracy and reliability of the data and analysis we provide. The task of establishingEstablishing and maintaining accurate and reliable data and analysis is challenging. If our data, including the data we obtain from third parties or directly from brokers through the Listing ManagerMarketing Center feature on CoStar and LoopNet, or analysis is not current, accurate, comprehensive or reliable, we could experience reduced demand for our services or be subject to legal claims by our customers, either of which could result in lower revenues and higher expenses.


Market volatility may have an adverse effect on our stock price. The trading price of our common stock has fluctuated widely in the past, and we expect that it will continue to fluctuate in the future. The price could fluctuate widely based on numerous factors, including: economic factors or conditions; quarter-to-quarter variations in our operating results; changes in analysts’ estimates of our earnings; announcements by us or our competitors of technological innovations, new services, or other significant or strategic information; general conditions in the commercial real estate industry; general conditions of local, national or global economies; developments or disputes concerning copyrights or proprietary rights or other legal proceedings; and regulatory developments. In addition, the stock market in general, and the shares of Internet-related and other technology companies in particular, have historically experienced extreme price fluctuations. This volatility has had a substantial effect on the market prices of securities issued by many companies for reasons unrelated to the operating performance of the specific companies and may have the same effect on the market price of our common stock.

Competition could render our services uncompetitive and reduce our profitability. The markets for information systems and services and for online marketplaces in general is highly competitive and rapidly changing. Competition in these markets may increase further if economic conditions or other circumstances cause customer bases and customer spending to decrease and service providers to compete for fewer customer resources. Our existing competitors, or future competitors, may have greater name recognition, larger customer bases, better technology or data, lower prices, easier access to data, greater user traffic or greater financial, technical or marketing resources than we have. Our competitors may be able to undertake more effective marketing campaigns, obtain more data, adopt more aggressive pricing policies, make more attractive offers to potential employees, subscribers, advertisers, distribution partners and content providers or may be able to respond more quickly to new or emerging technologies or changes in user requirements. If we are unable to retain customers or obtain new customers, our revenues could decline. Increased competition could result in lower revenues and higher expenses, which would reduce our profitability.

Our focus on internal and external investments may place downward pressure on our operating margins. We continue to invest in our business, including internal investments in product development to expand the breadth and depth of services we provide to our customers and investments in sales and marketing to generate brand awareness. Our investment strategy is intended to increase our revenue growth in the future. Our operating margins may experience downward pressure in the short term as a result of investments. Furthermore, our investments may not have their intended effect or produce the expected results. In addition, our external investments may lose value and we may incur impairment charges with respect to such investments. Such impairment charges may negatively impact our profitability. If we are unable to successfully execute our investment strategy or if we fail to adequately anticipate and address potential problems, we may experience decreases in our revenues and operating margins.

If we are unable to enforce or defend our ownership and use of intellectual property, our business, brands, competitive position and operating results could be harmed. The success of our business depends in large part on our intellectual property, including


intellectual property involved in our methodologies, database,databases, services and software. We rely on a combination of trademark, trade secret, patent, copyright and other laws, nondisclosure and noncompetition provisions, license agreements and other contractual provisions and technical measures to protect our intellectual property rights. However, current law may not provide for adequate protection of our databases and the actual data. In addition, legal standards relating to the validity, enforceability and scope of protection of proprietary rights in Internet-relatedinternet-related businesses are uncertain and evolving, and changes in these standards may adversely impact the viability or value of our proprietary rights. We find our proprietary content on competitors' sites. If we are not successful in protecting our intellectual property, including our content, our brands and our business, results of operations and financial condition could be harmed. The same would be true if a court found that our services infringe other persons’ intellectual property rights. Any intellectual property lawsuits or threatened lawsuits in which we are involved, either as a plaintiff or as a defendant, have cost us and could continue to cost us a significant amount of time and money and distract management’s attention from operating our business. In addition, if we do not prevail on an intellectual property claim, this could result in a change to our methodology or information, analytics and online marketplace services and could reduce our profitability.


Effective trademark, trade secret, patent and copyright protection may not be available in every country in which we provide our services may be provided.services. The laws of certain countries do not protect proprietary rights to the same extent as the laws of the United StatesU. S. and,
26


therefore, in certain jurisdictions, we may be unable to protect our intellectual property and our proprietary technology adequately against unauthorized third-party copying or use, which could harm our competitive position. This risk will increase as we continue to expand our business into new international jurisdictions.


We seek to enforce our rights against people and entities that infringe our intellectual property, including through legal action. Taking such action may be costly, and we cannot ensure that such actions will be successful. Any increase in the unauthorized use of our intellectual property could make it more expensive for us to do business and harm our results of operations or financial condition.

We may not be able to successfully halt the operation of websites that aggregate our data, as well as data from other companies, such asor copycat websites that may misappropriate our data. Third parties may misappropriate our data through website scraping, robots or other means and aggregate and display this data on their websites with data from other companies.websites. In addition, “copycat” websites may misappropriate data on our website and attempt to imitate our brands or the functionality of our website. We may not be able to detect all such websites in a timely manner and, even if we could, technological and legal measures available to us may be insufficient to stop their operations. In some cases, particularly in the case of websites operating outside of the U.S., our available remedies may not be adequate to protect us againstoperations and the misappropriation of our data. Regardless of whether we can successfully enforce our rights against the operators of these websites, anyAny measures that we may take to enforce our rights could require us to expend significant financial or other resources.


Third party claims, litigation or government investigations to which we are subject or in which we become involved may significantly increase our expenses and adversely affect our stock price. Currently and from time to time, we are a party to various third party claims, lawsuits, or government investigations. Any lawsuits, threatened lawsuits or government investigations in which we are involved, whether as plaintiff or defendant, could cost us a significant amount of time and money, could distract management’s attention away from operating our business, could result in negative publicity and could adversely affect our stock price. In addition, if any claims are determined against us or if a settlement requires us to pay a large monetary amount or take other action that materially restricts or impedes our operations, our profitability could be significantly reduced and our financial position could be adversely affected. Our insurance may not be sufficient to cover any losses we incur in connection with litigation claims.

We may be subject to legal liability for collecting, displaying or distributing information. Because the content in our database is collected from various sources and distributed to others, we may be subject to claims for breach of contract, defamation, negligence, unfair competition or copyright or trademark infringement or claims based on other theories.theories, such as breach of laws related to privacy and data protection. We could also be subject to claims based upon the content that is accessible from our website through links to other websites or information on our website supplied by third parties. We could also be subject to claims that the collection or provision of certain information breached laws and regulations relating to privacy and data protection. Even if these claims do not result in liability to us, we could incur significant costs in investigating and defending against any claims and we could be subject to public notice requirements that may affect our reputation in the marketplace.reputation. Our potential liability for information distributed by us to others could require us to implement measures to reduce our exposure to such liability, which may require us to expend substantial resources and limit the attractiveness of our information, analytics and online marketplaces to users.


Our business depends on retaining and attracting highly capable management and operating personnel. Our success depends in large part on our ability to retain and attract management and operating personnel, including our President and Chief Executive Officer, Andrew Florance, and our other officers and key employees. Our business requires highly skilled technical, sales, management, web product and development, marketing and research personnel, who are in high demand and are often subject to competing offers. To retain and attract key personnel, we use various measures, including employment agreements, awards under


a stock incentive plan and incentive bonuses for key employees. These measures may not be enough to retain and attract the personnel we need or to offset the impact on our business of the loss of the services of Mr. Florance or other key officers or employees. 

An impairment in the carrying value of goodwill could negatively impact our consolidated results of operations and net worth. Goodwill and identifiable intangible assets not subject to amortization are tested annually by each reporting unit on October 1 of each year for impairment and are tested for impairment more frequently based upon the existence of one or more indicators. We assess the impairment of long-lived assets, identifiable intangibles and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Judgments made by management relate to the expected useful lives of long-lived assets and our ability to realize undiscounted cash flows of the carrying amounts of such assets. The accuracy of these judgments may be adversely affected by several factors, including the factors listed below:

Significant underperformance relative to historical or projected future operating results;
Significant changes in the manner of our use of acquired assets or the strategy for our overall business;
Significant negative industry or economic trends; or
Significant decline in our market capitalization relative to net book value for a sustained period.

These types of events or indicators and the resulting impairment analysis could result in goodwill impairment charges in the future, which would reduce our profitability. Impairment charges could negatively affect our financial results in the periods of such charges, which may reduce our profitability. As of December 31, 2018, we had approximately $1.6 billion of goodwill, including $1.6 billion in our North America operating segment and $38 million in our International operating segment.  

If we are unable to obtain or retain listings from commercial real estate brokers, agents, property owners and apartment property managers, our commercial real estate ("CRE") marketplace services, including but not limited to LoopNet, the Apartments.com network of rental websites, CoStar Showcase, LandandFarm.com and LandsofAmerica.com, could be less attractive to current or potential customers, which could reduce our revenues. The value of our CREreal estate marketplace services to our customers depends on our ability to increase the number of property listings provided and searches conducted. The success of our CRE marketplace services depends substantially onAs the number of property listings submitted byincreases, so does the utility of a marketplace's search, listing and marketing services. We depend substantially on brokers, agents, property owners and, in the case of apartment rentals, property managers. This is because an increase in the number ofmanagers to submit listings increases the utility of the online service and of its associated search, listing and marketing services.to our marketplaces. If agents marketing large numbers of property listings, such as large brokers in key real estate markets,these parties choose not to continue their listings with us, or choose to list them with a competitor, our CRE marketplace services could be less attractive to other real estate industry transaction participants, resulting in reduced revenue. Similarly, the value and utility of

Risks related to our other marketplaces, including BizBuySell and BizQuest, are also dependent on attracting and retaining listings.international operations


If we are unable to convince commercial real estate professionals that our CRE marketplace services are superior to traditional methods of listing, searching and marketing commercial real estate, they could choose not to use those services, which could reduce our revenues or increase our expenses. The primary source of new customers for our CRE marketplace services is participants in the commercial real estate community. Many commercial real estate professionals are accustomed to listing, searching and marketing real estate in traditional and off-line ways, such as by distributing print brochures, sharing written lists, placing signs on properties, word-of-mouth and newspaper advertisements. Commercial real estate and investment professionals may prefer to continue to use traditional methods or may be slow to adopt and accept our online products and services. If we are not able to persuade commercial real estate participants of the efficacy of our online products and services, they may choose not to use our CRE marketplace services, which could negatively impact our business. Similarly, if we are unable to convince the business and investment community to utilize our online business for sale marketplaces rather than traditional methods of listing and marketing businesses for sale, our revenues could be negatively affected.

If we are unable to increase our revenues or our operating costs are higher than expected, our profitability may decline and our operating results may fluctuate significantly. We may not be able to accurately forecast our revenues or future revenue growth rate. Many of our expenses, particularly personnel costs and occupancy costs, are relatively fixed. As a result, we may not be able to adjust spending quickly enough to offset any unexpected increase in expenses or revenue shortfall. We may experience higher than expected operating costs, including increased personnel costs, occupancy costs, selling and marketing costs, investments in geographic expansion, acquisition costs, communications costs, travel costs, software development costs, professional fees and other costs. If operating costs exceed our expectations and cannot be adjusted accordingly, our profitability may be reduced and our results of operations and financial position will be adversely affected. Additionally, we may not be able to sustain our revenue growth rates, and our percentage revenue growth rates may decline. Our ability to increase our revenues and operating profit will depend on increased demand for our services. Our sales are affected by, among other things, general economic and commercial real estate conditions. Reduced demand, whether due to changes in customer preference, a weakening of the U.S. or global economy, competition or other reasons, may result in decreased revenues and growth, adversely affecting our operating results.



Our current or future geographic expansion plans may not result in increased revenues, which may negatively impact our business, results of operations and financial position. Expanding into new markets and investing resources towards increasing the depth of our coverage within existing markets imposes additional burdens on our research, systems development, sales, marketing and general managerial resources. If we are unable to manage our expansion efforts effectively, if our expansion efforts take longer than planned or if our costs for these efforts exceed our expectations, our financial position could be adversely affected. In addition, if we incur significant costs to improve data quality within existing markets, or are not successful in marketing and selling our services in these markets or in new markets, our expansion may have a material adverse effect on our financial position by increasing our expenses without increasing our revenues, adversely affecting our profitability.

International operations expose us to additional business risks, which may reduce our profitability. Our international operations and expansion subject us to additional business risks, including: currency exchange rate fluctuations; adapting to the differing business practices and laws in foreign countries; including differing laws regarding privacy and data protection; difficulties in managing foreign operations; limited protection for intellectual property rights in some countries; difficulty in collecting accounts receivable and longer collection periods; costs of enforcing contractual obligations; impact of recessions in economies outside the U.S.; and potentially adverse tax consequences. In addition, international expansion imposes additional burdens on our executive and administrative personnel, systems development, research and sales departments and general managerial resources. If we are not able to manage our international operations successfully, we may incur higher expenses and our profitability may be reduced. Finally, the investment required for additional international expansion could exceedsometimes exceeds the profit generated from such expansion, which would reducereduces our profitability and may adversely affect our financial position.


Fluctuating foreign currencies may negatively impact our business, results of operations and financial position. Due to our acquisitions of CoStar U.K. Limited (formerly FOCUS Information Limited), Property and Portfolio Research Ltd., Grecam S.A.S., Realla Ltd., the assets of Belbex Corporate, S.L., Thomas Daily, as well as our expansion into Canada, aA portion of our business is denominated in the British Pound, Euroforeign currencies.

During periods of a result, fluctuations instrengthening U.S. dollar, our reported international sales and earnings could be reduced because foreign currencies may have an impact on our business, results of operations and financial position.translate into fewer U.S. dollars. Foreign currency exchange rates have fluctuated and may continue to fluctuate. Significant foreign currency exchange rate fluctuations may negatively impact our international revenue, which in turn affects our consolidated revenue. Currencies may be affected by internal factors, general economic conditions and external developments in other countries, all of which can have an adverse impact on a country’s currency. Currently, we are not party to any hedging transactions intended to reduce our exposure to exchange rate fluctuations. We may seek to enter into hedging transactions in the future, but we may be unable to enter into these transactions successfully, on acceptable terms or at all. We cannot predict whether we will incur foreign exchange losses in the future. Further, significant foreign exchange fluctuations resulting in a decline in the respective local currency may decrease the value of our foreign assets, as well as decrease our revenues and earnings from our foreign subsidiaries, which would reduce our profitability and adversely affect our financial position.

The economic effects of “Brexit” may affect relationships with existing and future customers and could have an adverse impact on our business and operating results. On June 23, 2016, the U.K. held a referendum in which British citizens approved an exit from the European Union (“E.U.”), commonly referred to as “Brexit.” On March 29, 2017,January 31, 2020, the United Kingdom provided its official notice toU.K. officially withdrew from the European Council that it intends to leave the European Union, commencingE.U., beginning a transition period of up to two years fornegotiations between the British government and the E.U. and other governments. On December 24, 2020, the E.U. and the U.K. announced they had entered into a post-Brexit deal on certain aspects of trade and other strategic and political issues. The impact of Brexit, the December 2020 post-Brexit agreement and the otherfuture relationship between the E.U. member states to negotiateand the U.K., including terms ofnot addressed in the withdrawal. Uncertainty over the terms of the U.K.’s withdrawal from the E.U.December 2020 agreement, remain uncertain.Such uncertainty could cause political and economic uncertainty in the U.K. and the rest of Europe, which could harm our business and financial results. In particular, Brexit caused and could result incontinue to cause significant volatility in global equity markets, currency exchange rates and other asset prices, including those related to real property. Brexit may also lead to divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate, and compliance with those laws and regulations may be cumbersome, difficult or costly. Further, Brexit may lead other E.U. member countries to consider referendums regarding their E.U. membership. We cannot yet predict the future implications of Brexit, including whether it could increase our cost of doing business or otherwise adversely affect our financial condition or results of operations.The impact to us from Brexit will depend, in part, on the outcome of tariff, trade, regulatory and other negotiations, the results of which are currently uncertain. This impact may affect not only our U.K. operations but operations in other parts of the E.U. Any transitional or permanent agreements resulting from such negotiations

Risks related to our indebtedness

We have a significant amount of indebtedness, which could potentially disrupt the markets we servedecrease our flexibility and the tax jurisdictions in which we operate.

A potential devaluation of the local currencies of our international customers relative to the U.S. dollar may impair the purchasing power of our international customers and could cause international customers to decrease or cancel orders, or terminate or fail to renew subscriptions for our services.

We translate sales and other results denominated in foreign currency into U.S. dollars for our financial statements. During periods of a strengthening U.S. dollar, our reported international sales and earnings could be reduced because foreign currencies may translate into fewer U.S. dollars. Resulting asset price volatility that could follow the withdrawal of the U.K. from the E.U. may create global economic uncertainty, which may cause our customers to closely monitor their costs and reduce their spending budgets on our products and services. In addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the U.K determines which E.U. laws to replace or replicate, and those laws and regulations may be cumbersome, difficult or costly in terms of compliance. Further, Brexit may lead other E.U. member countries to consider referendums regarding


their E.U. membership. Any of these effects of Brexit, among others, could adversely affect our business, financial condition, operating results and cash flows.

Changes in laws, regulations or fiscal and tax policies or the manner of their interpretation or enforcement could adversely impact our financial performance. New laws or regulations, or changes in existing laws or regulations, or the manner of their interpretation or enforcement, could increase our cost of doing business. In particular, there may be significant changes in U.S. laws and regulations by the current U.S. presidential administration that could affect a wide variety of industries and businesses, including our business. The current U.S. presidential administration has called for substantial change to fiscal and tax policies, and recently adopted tax reform legislation. If the current U.S. presidential administration materially modifies U.S. laws and regulations or fiscal and other tax policies, our business, financial condition and results of operations. As of December 31, 2021, we had approximately $1 billion of Senior Notes outstanding and an additional approximately $750 million available to be drawn under the 2020 Credit Agreement. There can be no assurance that our future cash flows will be sufficient to make payments of interest or principal on the Senior Notes or any amounts due and payable under the 2020 Credit Agreement. If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and could be adversely affected.

In December 2017, the United States enacted The Tax Cutsforced to reduce or delay investments and Jobs Act (the "Tax Act"), and various provisionscapital expenditures or to dispose of the new law may adversely affect us. Certain aspects of Tax Reform are unclear andmaterial assets or operations, seek additional debt or equity capital or restructure or refinance our indebtedness. We may not be clarified for some time. During 2018, the Department of the Treasury issued certain guidance in the form of noticesable to effect any such alternative measures on commercially reasonable terms or at all, and, proposed regulations with respecteven if successful, those alternative actions may not allow us to several provisions of the new legislation. We expect thatmeet our scheduled debt service obligations. Furthermore, we may incur substantial additional regulationsindebtedness, including secured indebtedness, and if we incur additional indebtedness or other guidance may be issued with respect toliabilities, the Tax Act in 2019 and subsequent years. We continue to examine the impact this tax reform legislation may have on our business. In addition, if federal, state, local or foreign tax authorities change applicable tax laws or issue new guidance, including in response to the Tax Act, our overall taxesrelated risks that we face could increase, and our business, financial condition or results of operations may be adversely impacted.intensify.


Our indebtedness could adversely affect us, including by decreasing our business flexibility and increasing our costs. The 2017 Credit Agreement provides for a $750 million revolving credit facility with a term of five years from a syndicate of financial institutions as lenders and issuing banks. The 20172020 Credit Agreement contains customary restrictive covenants imposing operating and financial restrictions on us, including restrictions that may limit our ability to engage in acts that we believe may be in our long-term best interests. These covenants restrict our ability and the ability of our domestic subsidiaries to, among other things, (i) incur additional indebtedness, (ii) create, incur assume or permit to exist any liens, (iii) enter into mergers, consolidationspay dividends or similar transactions, (iv) make investments and acquisitions, (v) make certain dispositionsother restricted payments, investments or acquisitions, (iv) merge or consolidate with another person, and (v) sell, assign, lease or otherwise dispose of assets, (vi) make dividends, distributionsall or substantially all of our assets. In addition, the 2020 Credit Agreement requires us to comply with a maintenance covenant that we will not exceed a total net leverage ratio, calculated as total consolidated debt, net of up to $1.0 billion of unrestricted cash and prepaymentscash equivalents, to consolidated EBITDA, of certain indebtedness and (vii) enter into certain transactions with affiliates.

4.50 to 1.00. The operating restrictions and financial covenants in the 20172020 Credit Agreement and any future financing agreements may limit our ability to finance future operations or capital needs, to engage in other business activities or to respond to changes in market conditions. Our ability to comply with any financial covenants could be affected materially by events beyond our control, and we may be unable to satisfy any such requirements. If we fail to comply with these covenants, we may need to seek waivers or amendments of such covenants, seek alternative or additional sources of financing or reduce our expenditures. We may be unable to obtain such waivers, amendments or alternative or additional financing on a timely basis or at all, or on favorable terms.


We are required to make periodic principal and interest payments pursuant to the termsA breach of the 2017covenants under the 2020 Credit Agreement. IfAgreement or the indenture that governs the Senior Notes could result in an event of default occurs,under the applicable indebtedness. Such a default may allow the creditors to accelerate the related debt and may result in the acceleration of any other debt to which a cross-acceleration provision applies. In the event the holders of the Senior Notes or our other debt accelerate the repayment of our borrowings, we and our subsidiaries may not have sufficient assets to repay that indebtedness.

Our borrowings under the 2020 Credit Agreement will carry a variable interest rate based on overdue amountsthe Euro Interbank Offered Rate (“EURIBOR”) or the London Interbank Offered Rate (“LIBOR”) as a benchmark for establishing the rate of interest. LIBOR is the subject of recent national, international and other regulatory guidance and proposals for reform. The U.K. authority that regulates LIBOR announced that it will increasenot compel banks to submit rates for the calculation of LIBOR after June 2023.The full impact of any transition away from LIBOR remains unclear. The 2020 Credit Agreement allows the Company and the lendersadministrative agent under the 20172020 Credit Agreement may declare all outstanding borrowings, togetherto amend the 2020 Credit Agreement to replace LIBOR with accrued interest and other fees, to be immediately due and payable and may exercise remedies in respect of the collateral. one or more Secured Overnight Financing Rate based rates or another alternative benchmark rate.We may not be able to repay all amounts dueagree

Negative conditions in the global credit markets may affect the liquidity ofOur indebtedness increases our vulnerability to general adverse economic and industry conditions; requires us to dedicate a portion of our long-term investments.  Currently,cash flow from operations to payments on indebtedness, reducing the availability of cash flow to fund capital expenditures, marketing and other general corporate activities; limits our long-term investments include mostly AAA-rated auction rate securities (“ARS”), which are primarily student loan securities supported by guarantees fromability to borrow additional funds; and may limit our flexibility in planning for, or reacting to, changes in our business and the Federal Family Education Loan Program (“FFELP”) of the U.S. Department of Education. Continuing negative conditions in the global credit markets have prevented some investors from liquidating their holdings of auction rate securities because the amount of securities submitted for sale has exceeded the amount of purchase orders for such securities. As of December 31, 2018, we held $11 million par value of ARS, all of which failed to settle at auctions. When an auction fails for ARSindustries in which we have invested, weoperate.

A lowering or withdrawal of the ratings assigned to our debt securities by rating agencies may be unable to liquidate some or all of these securities at par. In the event we need or desire to immediately access these funds, we will not be able to do so until aincrease our future auction on these investments is successful, a buyer is found outside the auction process or an alternative action is determined. If a buyer is found but is unwilling to purchase the investments at par, we may incur a loss, which wouldborrowing costs, reduce our profitabilityaccess to capital or result in the loss of certain covenant suspensions. Our debt rating could be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, future circumstances relating to the basis of the rating, such as adverse changes, warrant. Any future lowering of our ratings likely would make it more difficult or more expensive for us to obtain additional debt financing.

In addition, the 2020 Credit Agreement provides that, during any period of time in which we maintain a corporate investment grade rating from any two of Standard & Poor’s Rating Services, Fitch Ratings, Inc. or Moody’s Investors Services, Inc. (such period, a “Covenant Suspension Period”), certain customary negative and adversely affectaffirmative covenants contained in the 2020 Credit Agreement are suspended, including the covenants restricting affiliate transactions, incurrence of indebtedness, investments, asset sales and restricted payments. A lowering of one or both of our financial position.

Ourinvestment grade ratings would result in increased compliance costs and would impose certain operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to seasonality and market cyclicality, eachrestrictions, either of which could causebe materially adverse to our stock price to be negatively affected. The commercial real estate market may be influenced by general economic conditions, economic cycles, annual seasonality factorsoperations and many other factors, which in turn may impact our financial results. The market is large and fragmented. The different sectors of the industry, such as office, industrial, retail, multifamily, and others, are influenced differently by different factors, and have historically moved through economic cycles with different timing. As such, it is difficult to estimate the potential impact of economic cycles and conditions



or seasonality from year-to-year on our overall operating results. In addition, our results may be impacted by seasonality. The timing of widely observed holidays and vacation periods, particularly slowdowns during the end-of-year holiday period, and availability of real estate agents and related service providers during these periods, could significantly affect our quarterly operating results during that period. If we are unable to adequately respond to economic, seasonal or cyclical conditions, our revenues, expenses and operating results may fluctuate from quarter to quarter. Our operating results, revenues and expenses may fluctuate for many reasons, including those described below and elsewhere in this Annual Report on Form 10-K:
Rates of subscriber adoption and retention;
Timing of our sales conference or significant marketing events;
A slow-down during the end-of-year holiday period;
Changes in our pricing strategy and timing of changes;
The timing and success of new service introductions and enhancements;
The shift of focus from, or phase out of services that overlap or are redundant with other services we offer;
The amount and timing of our operating expenses and capital expenditures;
Our ability to control expenses;
The amount and timing of non-cash stock-based charges;
Costs related to acquisitions of businesses or technologies or impairment charges associated with such investments and acquisitions;
Competition;
Changes or consolidation in the real estate industry;
Our investments in geographic expansion and to increase coverage in existing markets;
Interest rate fluctuations;
Successful execution of our expansion and integration plans;
The development of our sales force;
Foreign currency and exchange rate fluctuations;
Inflation; and
Changes in client budgets.

These fluctuations or seasonality effects could negatively affect our results of operations during the period in question and/or future periods or cause our stock price to decline. In addition, changes in accounting policies or practices may affect our level of net income. Fluctuations in our financial results, revenues and expenses may cause the market price of our common stock to decline.

The consent order approved by the Federal Trade Commission in connection with the LoopNet merger imposes conditions that could have an adverse effect on us and our business, and failure to comply with the terms of the consent order may result in adverse consequences for the combined company.On April 26, 2012, the FTC accepted the consent order in connection with the LoopNet merger that was previously agreed to among the FTC staff, CoStar, and LoopNet on April 17, 2012. The consent order was subject to a 30-day public comment period, and on August 29, 2012, the FTC issued its final acceptance of the consent order.

The consent order, which is publicly available on the FTC's website at http://www.ftc.gov/, requires us to maintain certain business practices that the FTC believes are pro-competitive.  For example, the consent order requires us to license our products to customers who have bought its competitors' products on a non-discriminatory basis. In addition, we are required to provide the FTC with advance written notification of certain acquisitions for which notification would not otherwise be required under the Hart-Scott-Rodino Premerger Notification Act. This provision of the consent order requiring CoStar to provide the FTC with advance written notification of certain acquisitions could prevent us from closing certain acquisitions or add significant time and cost to these potential acquisitions, ultimately making an acquisition prohibitive or preventing us from realizing anticipated benefits of an acquisition. In the event that we fail or are unable to comply with the terms of the consent order, we could be subject to an enforcement proceeding that could result in substantial fines and/or injunctive relief.

Changes in accounting and reporting policies or practices may affect our financial results or presentation of results, which may affect our stock price. Changes in accounting and reporting policies or practices could reduce our net income, which reductions may be independent of changes in our operations. These reductions in reported net income could cause our stock price to decline.

Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operations

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains “forward-looking statements,” including statements about our beliefs and expectations. There are many risks and uncertainties that could cause actual results to differ materially from those discussed in the forward-looking statements. Potential factors that could cause actual results to differ materially from those discussed in any forward-looking statements include, but are not limited to, those stated above in Item 1A. under the headings “Risk Factors - Cautionaryheading “Cautionary Statement Concerning Forward-Looking Statements” and in Item 1A. under the heading “Risk Factors,” as well as those described from time to time in our filings with the Securities and Exchange Commission.


All forward-looking statements are based on information available to us on the date of this filing and we assume no obligation to update such statements, whether as a result of new information, future events or otherwise. The following discussion should be read in conjunction with our Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the Securities and Exchange Commission and the consolidated financial statements and related notes included in this Annual Report on Form 10-K.


Overview

We are the number one provider of information, analytics and online marketplaces to the commercial real estate industry in the U.S. and the U.K. based on the fact that we offer the most comprehensive commercial real estate database available; have the largest research department in the industry; own and operate leading online marketplaces for commercial real estate and apartment listings in the U.S. based on the numbers of unique visitors and site visits per month; provide more information, analytics and marketing services than any of our competitors. We created and compiled our standardized platform of information, analytics and online marketplace services where industry professionals and consumers of commercial real estate, including apartments, and the related business communities, can continuously interact and facilitate transactions by efficiently accessing and exchanging accurate and standardized real estate-related information.

Our subscription-based services consist primarily of information, analytics and online marketplace services offered over the internet to commercial real estate industry and related professionals. Our services are typically distributed to our clients under subscription-based license agreements that renew automatically, a majority of which have a term of one year. Upon renewal, subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations. To encourage clients to use our services regularly, we generally charge a fixed monthly amount for our subscription-based services rather than charging fees based on actual system usage or number of paid clicks. Our service offerings span all commercial property types, including office, retail, industrial, multifamily, commercial land, mixed-use and hospitality. Depending on the type of service, contract rates are generally based on the number of sites, number of users, organization size, the client's business focus, geography, the number and types of services to which a client subscribes, the number of properties a client advertises and the prominence and placement of a client's advertised properties in the search results, as applicable. Our subscription clients generally pay contract fees in advance on a monthly basis, but in some cases may pay us in advance on a quarterly or annual basis.
We also provide market research, portfolio and debt analysis, management and reporting capabilities, and real estate and lease management solutions, including lease administration and abstraction services, to commercial customers, real estate investors and lenders via our other service offerings.


Our principal information, analytics and online marketplace services are described in the following paragraphs by type of service:


Information and AnalyticsCoStar


CoStar Suite®. Our® is our subscription-based information services consist primarily of CoStar Suite services. CoStar Suite is sold as aintegrated platform of service offerings consisting of CoStar Property Professional®, CoStar COMPS Professional®and CoStar Tenant® and through our mobile applications, CoStar Mobile App and CoStar Go.

CoStar's revenue growth rates increased in 2021 compared to 2020 as the average number of subscribers increased in 2021 compared to 2020 and we resumed annual price increases for contract renewals occurring in the third quarter of 2021 after a temporary suspension. We expect CoStar revenue growth rates to increase in 2022 compared to 2021 as a result of signing up new subscribers, existing subscribers upgrading their subscriptions and the resumption of annual price increases.


Information services.

We provide real estate and lease management technology solutions, including lease administration, lease accounting and abstraction services, through our CoStar Real Estate Manager® service offerings, as well as portfolio and debt analysis, management and reporting capabilities through our CoStar Investment Analysis and CoStar Risk Analytics® service offerings. We also provide analytics and benchmarking reports for the hospitality industry. STARTM reports are provided on a subscription basis, but we also provide one-time or ad hoc reports or analysis on a transaction-basis. We provide information services internationally through our Grecam, Belbex and Thomas Daily businesses in France, Spain and Germany, respectively. Information services' revenue growth rates decreased in 2021 compared to 2020 primarily due to the STR acquisition in 2019 which resulted in a full year of results in 2020. We expect information services revenue growth rates in 2022 to remain consistent with 2021.

On February 21, 2018, we completeddestination for their available rental units and offers renters a platform for searching for available rentals. Apartments.com also earns transaction-based revenue primarily from providing online tenant applications, including background and credit checks, and rental payment processing. Apartments.com has continued to successfully increase traffic to its network of sites, year-over-year, resulting in increased leads to customers. As leads per ad have increased, Apartments.com’s lower priced ad packages are generating more leads than top-level packages were generating approximately one year ago. In addition, rental vacancy rates have declined relative to historical averages reducing demand for top-level packages. As a result, customers began selecting lower-priced ad packages in the acquisitionsecond half of ForRent,2021. Consequently, net new bookings declined year-over-year in 2021 resulting in a division of Dominion Enterprises, includingdecrease in the ForRent.com, AFTER55.com, CorporateHousing.com and ForRentUniversity.com apartment marketing sites.Multifamily revenue growth rates in 2021 compared to 2020. We continuehave implemented a revised pricing strategy to integrate, develop and cross-sellalign prices at each product level with the services offered by ForRent. On November 8, 2018, we acquired Cozy Services, Ltd. ("Cozy"), a leading provider of online rental solutions that provides a broad spectrum of services to both landlords and tenants, including property listings, rent estimates, rental applications, tenant screening, online rent payments and expense tracking. See Note 4 to the Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussionvalue of the acquisitionleads delivered. We expect multifamily revenue growth rates in 2022 to decrease when compared to 2021 due to lower net new booking activity in 2021.

LoopNet

Our LoopNet network of Cozy.

Commercial property and land. Our LoopNetcommercial real estate websites offer subscription-based, online marketplace services that enable commercial property owners, landlords and real estate agents working on their behalf to listadvertise properties for sale or for lease and to submit detailed information about property listings. Commercial real estate agents, buyers and tenants use LoopNet'sthe LoopNet network of online marketplace services to search for available property listings that meet their criteria. This product offering also includes Realla in the United Kingdom and BureauxLocaux in France which was acquired on October 1, 2021. LoopNet's revenue growth rates decreased in 2021 when compared to 2020 as growth in the average price per listing declined in 2021 when compared to 2020. We expect LoopNet revenue growth rates in 2022 to decrease when compared to 2021.

Residential

On October 12, 2018,December 22, 2020, we acquired allHomesnap®, an online and mobile software platform that provides subscription-based access to applications that manage residential real estate agent workflow and marketing campaigns delivered on third-party platforms. On May 24, 2021, we acquired Homes.com®, a residential advertising and marketing services company primarily operating through its portal, Homes.com. We expect residential revenue for 2022 to decline when compared to 2021 due to the discontinuation of the issued share capitalcertain Homes.com products and services, which is expected to be partially offset by expected increases in sales of Realla Ltd. ("Realla")Homesnap products and services.

Other Marketplaces

Our other marketplaces include Ten-X®, the operator of a commercial property listings and data managementan online auction platform in the U.K., including a free-to-list search engine for commercial property listings. See Note 4 to the Notes to the Consolidated Financial Statementsreal estate which was acquired on June 24, 2020.

Our and FindaFranchise and our Land.com network of sites, which includes LandsofAmerica, LandAndFarm and LandWatch®. The BizBuySell network provides online marketplaces for businesses for-sale and our Land.com network of sites provide online marketplaces for rural lands for-sale. Overall, revenues in other marketplaces increased during 2021 compared to 2020 primarily due to two additional quarters of Ten-X revenue included in 2021. We expect other marketplaces revenue for sale, includes LandsofAmerica, LandAndFarm2022 to increase over 2021 as more properties are sold on Ten-X .

Subscription-based Services

The majority of our revenue is generated from service offerings which are distributed to our clients under subscription-based agreements that typically renew automatically and LandWatch®have a term of at least one year. We recognize subscription revenues on a straight-line basis over the life of the contract.


As ofFor the years ended December 31, 2018, 20172021, 2020 and 20162019, our annualized net new bookings of subscription-based services on all contracts were approximately $50$217 million, $43$184 million and $29$210 million, respectively, calculated based on the annualized amount of change in our sales resulting from all new subscription-based contracts or upsalesupgrades on all existing subscription-based contracts, less write downswrite-downs and cancellations, for the period reported. We recognize subscription revenues on a straight-line basis over the life of the contract. Net new bookings is considered a key indicator of future subscription revenue growth and is also used as a metric of salesforcesales force productivity by managementus and investors.

For However, information regarding net new bookings is not comparable to, nor should it be substituted for, an analysis of our revenues over time. Revenue from our subscription-based contracts was approximately 93%, 95% and 96% of total revenue for the years ended December 31, 2018, 20172021, 2020 and 2016,2019, respectively. The decline in the percentage of our revenue from subscription-based contracts from 2019 to 2020 and from 2020 to 2021 was primarily due to the acquisitions of companies which contained a higher percentage of transaction-based revenue than our legacy businesses.

For the trailing twelve months ended December 31, 2021, 2020 and 2019, our contract renewal raterates for existing CoStar Group company-wide subscription-based services on annualfor contracts waswith a term of at least one year were approximately 92%, 89% and 90%, 91% and 90% respectively, and,and; therefore, our cancellation raterates for those services wasfor the same periods were approximately 10%8%, 9%,11% and 10%, respectively. Our contract renewal rate is a quantitative measurement that is typically closely correlated with our revenuerevenue results. As a result, management also believeswe believe that the rate may be a reliable indicator of short-term and long-term performance.performance absent extraordinary circumstances. Our trailing twelve-month contract renewal rate may decline if, among other reasons,as a result of negative economic conditions, lead to greater business failures and/or consolidations among our clients, reductions in customer spending or decreases in our customer base. Revenue from our subscription-based contracts with a term of at least one year was approximately 77%, 80% and 82% of total revenue for the trailing twelve months ended December 31, 2021, 2020 and 2019, respectively. The decline in the percentage of our revenue from subscription-based contracts from 2019 to 2020 and from 2020 to 2021 was primarily due to the acquisitions of companies which contained a higher percentage of transaction-based revenue than our legacy businesses, as well as, increases in our sales of shorter term advertising products.

Impact of the COVID-19 Pandemic

While the impact of the COVID-19 pandemic continues to evolve, it did not materially affect our consolidated financial statements during 2020 or 2021. We are closely and continually monitoring the impact of the COVID-19 pandemic on our business, employees, customers and communities. We continue to monitor the guidelines and mandates provided by governmental and health authorities and plan to continue adapting our business operations when and as deemed appropriate to comply with these guidelines and mandates and to respond to changing circumstances. Most of our workforce has been fully vaccinated against COVID-19 and, where permitted, has returned to the office. We have resumed in-person marketing events and some business travel. The global workforce has been operating in an extraordinary and mostly digital and remote manner as the world adapted during the COVID-19 pandemic. During this time, many working adults moved to different locations and adjusted to a different way of living. As we transitioned our employees back to the office, we experienced, and we expect to continue to experience, attrition among our workforce resulting in increased costs. Continued attrition or the inability to replenish and grow our work force may result in work disruptions in the future. Overall, the increased direct spend related to the COVID-19 pandemic, including office reconfiguration to enable social distancing and employee hiring and retention programs, has not been material to date and has had minimal impact on our financial position and operating results.

It is currently unclear how the commercial real estate industry will ultimately be impacted by the COVID-19 pandemic as businesses formulate and execute plans for employees to return to the office, implement hybrid work arrangements – allowing work from the office or home, or switch to all work from home. If the demand for office space decreases significantly, there could be a downturn in the commercial real estate market which may materially adversely affect many of our clients. A depressed commercial real estate market would have a negative impact on our core customer base, which could impact our customers’ ability to subscribe and pay for our services and reduce demand for our services. Reduced demand and increased cancellations could cause our revenues or our revenue growth rates to decline and reduce our profitability.

During 2021, excluding our multifamily service offering, which is discussed under Service Offerings above, our company-wide net new bookings and renewal rates for subscription-based services have returned to pre-pandemic levels. In addition, we saw improvements in collection trends along with improvements in the economy which led us to reduce our allowance for credit losses previously taken. Due to the uncertainty associated with the COVID-19 pandemic and any resulting economic impacts, we will continue to monitor these trends and the effect on our results of operations. Any anticipated changes in financial performance discussed in this report are based on our current observations and experience and involve estimates and assumptions. As the future extent and duration of the effects of the COVID-19 pandemic remain unclear, our estimates and assumptions may evolve as conditions change and actual results may vary.

The effects of the pandemic have not affected our ability to date to access funding on reasonably similar terms as were available to us prior to March 2020.We strengthened our liquidity position through an equity offering of common stock in May 2020 and an offering of Senior Notes and amendment and restatement of our credit facility in early July 2020. See Note 11 and Note 15 in this Annual Report on Form 10-K for further discussion of our equity and Senior Notes offerings in 2020 and the 2020 Credit Agreement.

Development, Investments and Expansion


We plan to continue to invest in our business and our services, evaluate strategic growth opportunities, and pursue our key priorities as described below, while we closely monitor the economic developments from the COVID-19 pandemic and manage our response to such developments. We are committed to supporting, improving and enhancing our information, news, analytics and online marketplace solutions, including expanding and improving our offerings for our client base and site users, including property owners, property managers, buyers, commercial tenants and renters.residential renters and buyers. We expect to continue our software development efforts to improve existing services, introduce new services, integrate and cross-sell services, integrate recently completed acquisitions and expand and develop supporting technologies for our research, sales and marketing organizations. We may reevaluate our priorities as the COVID-19 pandemic and its economic impact continues to evolve.

Our key priorities for 2022 currently include:

Continuing to develop and invest in residential marketplaces. Our residential team is creating new and improved tools to help consumers have been,a highly contextual experience when searching for homes supported by high quality media and in-depth attributes of homes and details of the surrounding neighborhoods, parks and schools and to help consumers collaborate with their agent and other consumers. We are also creating new and improved tools to help agents promote their residential listings, connect with buyers and sellers and streamline their daily workflow. In October 2021, we reached an agreement to create, maintain and market a consumer-facing search website and mobile app for the Real Estate Board of New York's Residential Listing Service. In accordance with that agreement, we are developing a

custom version of the Homesnap platform, branded as Citysnap™, specifically for the five boroughs of New York City. To support the expanded product offering, we expect to increase our investment in residential products in 2022 by approximately $200 million. The most significant components of our investment are expected to be content development, marketing costs and technology resources.The increase in our investment in residential products in 2022 is expected to reduce our results of operations and cash flow from operations for the year ended December 31, 2022. We plan to continue integrating, further developingto monitor and cross-sellingevaluate these investments and adjust our services. To generateresidential business strategy and level of investment as we determine appropriate.

Continuing to invest in CoStar, including:

Enhancing benchmarking capabilities. We integrated STR's data into CoStar in 2021 and continue to develop dynamic analytics for and additional coverage of hospitality properties. We plan to apply STR's benchmarking capabilities within CoStar;

Developing CMBS Analytics, which will aggregate loan and property data across covered markets. The initial CMBS Analytics release is expected to include loan origination metrics, distressed loan levels and maturity volumes, as well as detailed revenue and expense information. In later releases of this solution, we plan to include detailed prepayment information on disposed loans;

Continuing to develop a solution for lenders that leverages CoStar's Risk Analytics capabilities to support lenders with risk management, underwriting, surveillance and compliance reporting. Lender was released in beta in February 2022 and provides a focus on portfolio risk analytics and surveillance to help lenders meet regulatory and accounting requirements. Subsequent releases are expected to focus on loan origination and underwriting; and

Expanding our international presence by hiring managers and teams of field researchers in European markets.

Continuing to improve and market our Apartments.com service offerings to create the best and most comprehensive consumer rental search experience as well as continuing to advance the digital rental experience that allows renters to apply for leases and make rent payments, and for landlords to receive and assess tenant applications online through a single platform. We seek user feedback as we work to improve our services and continue to aggressively market our multifamily listing services in an effort to attract consumers and, in turn, provide more value to advertisers. Our Apartments.com marketing spending is focused on enhanced brand awareness and site traffic for our listing sites, we utilize a multi-channel marketing campaign, including television and radio advertising, online/digital advertising, social media and out-of-home ads, and search engine marketing. We expect to continue to invest in sales and marketing, consistent with historical levels, to promote our sites in 2019. As we continue to assess the success and effectiveness of our marketing campaign, we will continue to work to determine the optimal level and focus of our marketing investment for our multifamily listing services for future periods.

Our key priorities for 2019 include:

Continuingperiods and may adjust our marketing spend and focus as we deem appropriate. Apartments.com has been successful in generating increased traffic to developthe network and as a result is delivering increased leads per ad to customers. We have implemented a new and improve existing, online rental property service offerings forpricing strategy to align the apartments industry.product level prices with the value of the leads generated. We planintend to utilize acquired platforms, including Cozy, along withmonitor our previously developed and newly developed technologies,new pricing strategy to create a complete digital rental experience that enables renters to apply for leases, for landlords to run tenant credit and background checks and for landlords and tenants to generate and enter into leases and to make and process payments, all online through a single platform.



Continuing to develop and enhance CoStar Suite by making additional investments in analytical capabilities and developing products offerings with new capabilities focused on owners and lenders of commercial real estate. We also plan to invest in integratingdetermine whether current pricing reflects the technology and infrastructure from other existing products into the CoStar Suite platform, including CoStar Real Estate Manager, in order to leverage data across our platforms and provide customers with additional functionality. We plan to invest further in our daily newsletter for U.S. subscribers, including providing curated contentincreased lead generation we are delivering to our largest markets, and more personalized information.customers.

Continuing to invest in the LoopNet marketplace by enhancingmarketplaces. To support the LoopNet marketplaces, we implemented training and incentive programs for our existing sales team to increase sales of LoopNet advertisements, with a focus on brokers and property owners. We have enhanced the content on the site, includingLoopNet.com (including high-quality imagery,imagery), seeking targeted advertisements and are providing premium marketing services (such as LoopNet Diamond, Platinum and Gold Ads) that increase a property listing’s exposure, and adding more content for premium listings to better meet the needs of a broader cross section of the commercial real estate industry. ContinuingWe are continuing our plans to invest in our research operationsrecruit and develop a dedicated LoopNet sales team to help support continued growth of our information and analytics offerings. In furtherance of both of these priorities,grow the business. To generate brand awareness and site traffic for the LoopNet.com network, we planexpect to continue to generate awarenessincur costs in a multi-media marketing campaign, reinforced with search engine optimization efforts and promote usage of Listing Manager, an online tool that allows customers with CoStar or LoopNet listingswill continue to updatework to determine the optimal level and manage their listings directly online.

Continuing to invest in the growth ofTen-X auction platform. We have integrated the Ten-X platform with both CoStar and LoopNet to expand the audience for Ten-X auctions to include our international business. We plan to integrate Realla with our CoStar U.K. operations, including development of a single point of data entry to allow our clients to simultaneously arrange to display their commercial real estate listings throughusers. We also plan to enhance access to Ten-X's data room information from CoStar and LoopNet. To increase exposure of properties to be auctioned on Ten-X, we are allocating banner space on both our CoStar and LoopNet sites for advertising for Ten-X properties. We continue to execute our plan to expand the CoStar Suite service offeringTen-X sales force and focus on increasing the number of qualified bidders and the number of owners bringing properties to also make them visiblethe site.

We intend to continue to assess the need for additional investments in our business in addition to the investments discussed above, in order to develop and distribute new services and functionality within our current platform or expand the reach of, or otherwise improve, our current service offerings. Any future product development or expansion of services, combination and coordination of services or elimination of services or corporate expansion, development or restructuring efforts could reduce our profitability and increase our capital expenditures. Any new investments, changes to our service offerings or other unforeseen events could cause us to experience reduced revenues or generate losses and negative cash flow from operations in the future. Any development efforts must comply with our credit facility, which contains restrictive covenants that restrict our operations and use of our cash flow and may prevent us from taking certain actions that we believe could increase our profitability or otherwise enhance our business.


For further discussion of our Company, strategy and products, see our business overview set forth in "Item 1. Business" in this Annual Report on Form 10-K.


Non-GAAP Financial Measures


We prepare and publicly release quarterly unaudited financial statements prepared in accordance with generally accepted accounting principles (“GAAP”). We also disclose and discuss certain non-GAAP financial measures in our public releases, investor conference calls and filings with the Securities and Exchange Commission. The non-GAAP financial measures that we may disclose include net income before interest and(expense) income, other (expense) income, (expense), loss on debt extinguishment, income taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share (also referred to as “non-GAAP EPS”).share. EBITDA is our net income before interest and(expense) income, other (expense) income, (expense), loss on debt extinguishment, income taxes, depreciation and amortization. We typically disclose EBITDA on a consolidated and an operating segment basis in our earnings releases, investor conference calls and filings with the Securities and Exchange Commission. Adjusted EBITDA is different from EBITDA because we further adjust EBITDA for stock-based compensation expense, acquisition- and integration-related costs, restructuring costs and settlements and impairments incurred outside our ordinary course of business. Adjusted EBITDA margin represents adjusted EBITDA divided by revenues for the period. Non-GAAP net income and non-GAAPis determined by adjusting our net income per diluted share are similarly adjusted for stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, settlement and impairment costs incurred outside our ordinary course of business and loss on debt extinguishment, as well as amortization of acquired intangible assets and other related costs. From this figure, wecosts, and then subtractsubtracting an assumed provision for income taxes to arrive attaxes. Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income. income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share.

We may disclose adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share on a consolidated basis in our earnings releases, investor conference calls and filings with the Securities and Exchange Commission. The non-GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help our investors meaningfully evaluate and compare our results of operations to our previously reported results of operations or to those of other companies in our industry.




We view EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share as operating performance measures and as such wemeasures. We believe that the most directly comparable GAAP financial measure to EBITDA, adjusted EBITDA and non-GAAP net income is net income. We believe the most directly comparable GAAP financial measures to non-GAAP net income per diluted share and adjusted EBITDA margin are net income per diluted share and net income divided by revenue, respectively. In calculating EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share, we exclude from net income the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share are not measurements of financial performance under GAAP and should not be considered as a measure of liquidity, as an alternative to net income or as an indicator of any other measure of performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share as a substitute for any GAAP financial measure, including net income.income and net income per diluted share. In addition, we urge investors and potential investors in our securities to carefully review the GAAP financial information included as part of our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q that are filed with the Securities and Exchange Commission, as well as our quarterly earnings releases, and compare the GAAP financial information with our EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share.

EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share may be used by management to internally measure our operating and management performance and may be used by investors as supplemental financial measures to evaluate the performance of our business. We believe that these non-GAAP measures, when viewed with our GAAP results and accompanying reconciliations, provide additional information to investors that is useful to understand the factors and trends affecting our business.business without the impact of certain acquisition-related items. We have spent more than 30 years building our database of commercial real estate information and expanding our markets and services partially through acquisitions of complementary businesses. Due to the expansion of our information, analytics and online marketplace services, which has includedthese acquisitions, our net income has included significant charges for amortization of acquired intangible assets, depreciation and other amortization, acquisition- and integration-related costs, restructuring costs and loss on debt extinguishment. Adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share exclude these charges and provide meaningful information about the operating performance of our business, apart from charges for amortization of acquired intangible assets, depreciation and other amortization, acquisition- and integration-related costs, restructuring costs; settlement and impairment costs incurred outside our ordinary course of business. We believe the disclosure of non-GAAP measures can help investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year.year without the impact of these items. We also believe the non-GAAP measures we disclose are measures of our ongoing operating performance because the isolation of non-cash charges, such as amortization and depreciation, and other items, such as interest (expense) income, other (expense) income, income taxes, stock-based compensation expenses, acquisition- and integration-related costs, restructuring costs;costs, loss on debt extinguishment and settlement and impairment costs incurred outside our ordinary course of business, provides additional information about our cost structure, and, over time, helps track our operating progress. In addition, investors, securities analysts and others have regularly relied on EBITDA and may rely on adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income or non-GAAP net income per diluted share to provide a financial measure by which to compare our operating performance against that of other companies in our industry.


Set forth below are descriptions of financial items that have been excluded from net income to calculate EBITDA and the material limitations associated with using this non-GAAP financial measure as compared to net income:


Amortization of acquired intangible assets in cost of revenues may be useful for investors to consider because it represents the diminishing value of any acquired trade names and other intangible assets and the use of our acquired technology, which is one of the sources of information for our database of commercial real estate information. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.


Amortization of acquired intangible assets in operating expenses may be useful for investors to consider because it represents the estimated attrition of our acquired customer base. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.


Depreciation and other amortization may be useful for investors to consider because they generally represent the wear and tear on our property and equipment used in our operations. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.


The amount of interest (expense) income and other (expense) income and expense we generate and incur may be useful for investors to consider and may result in current cash inflows.inflows and outflows. However, we do not consider the amount of interest (expense) income and other (expense) income and expense to be a representative component of the day-to-day operating performance of our business.




The amount of loss on our debt extinguishment may be useful for investors to consider because it generally represents losses from the early extinguishment of debt. However, we do not consider the amount of the loss on debt extinguishment to be a representative component of the day-to-day operating performance of our business.

Income tax expense may be useful for investors to consider because it generally represents the taxes which may be payable for the period and the change in deferred income taxes during the period and may reduce the amount of funds otherwise available for use in our business. However, we do not consider the amount of income tax expense to be a representative component of the day-to-day operating performance of our business.


The amount of loss on our debt extinguishment may be useful for investors to consider because it generally represents losses from the early extinguishment of debt. However, we do not consider the amount of the loss on debt extinguishment to be a representative component of the day-to-day operating performance of our business.

Set forth below are descriptions of additional financial items that have been excluded from EBITDA to calculate adjusted EBITDA and the material limitations associated with using this non-GAAP financial measure as compared to net income:


38


Stock-based compensation expense may be useful for investors to consider because it represents a portion of the compensation of our employees and executives. Determining the fair value of the stock-based instruments involves a high degree of judgment and estimation and the expenses recorded may bear little resemblance to the actual value realized upon the future exercise or termination of the related stock-based awards. Therefore, we believe it is useful to exclude stock-based compensation in order to better understand the long-term performance of our core business.


The amount of acquisition- and integration- relatedintegration-related costs incurred may be useful for investors to consider because theysuch costs generally represent professional service fees and direct expenses related to acquisitions. Because we do not acquire businesses on a predictable cycle, we do not consider the amount of acquisition- and integration- relatedintegration-related costs to be a representative component of the day-to-day operating performance of our business.


The amount of settlement and impairment costs incurred outside of our ordinary course of business may be useful for investors to consider because they generally represent gains or losses from the settlement of litigation matters or impairments on acquired intangible assets. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.


The amount of restructuring costs incurred may be useful for investors to consider because they generally represent costs incurred in connection with a change in a contract or a change in the makeup of our properties or personnel. We do not consider the amount of restructuring related costs to be a representative component of the day-to-day operating performance of our business.


The financial items that have been excluded from our net income to calculate non-GAAP net income and non-GAAP net income per diluted share are amortization of acquired intangible assets and other related costs, stock-based compensation, acquisition- and integration- relatedintegration-related costs, restructuring and related costs and settlement and impairment costs incurred outside our ordinary course of business. These items are discussed above with respect to the calculation of adjusted EBITDA together with the material limitations associated with using this non-GAAP financial measure as compared to net income. WeIn addition to these exclusions from net income, we subtract an assumed provision for income taxes to calculate non-GAAP net income. In 2017 and 2016, we assumedWe assume a 38%25% tax rate, which approximated our historical long-term statutory corporate tax rate, excluding the impact of discrete items. In 2018 we assumed a 25% tax rate which reflects our full year 2018 statutory tax rate. The decrease in our tax rate in 2018 is mainly due to the Tax Act which reduced the U.S. federal corporate income tax rate from 35% to 21% effective January 1, 2018.

Adjusted EBITDA margin represents adjusted EBITDA divided by revenues for the period.

Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share.


Management compensates for the above-described limitations of using non-GAAP measures by using a non-GAAP measure only to supplement our GAAP results and to provide additional information that is useful to investors to understand the factors and trends affecting our business.

Software Development Expenses. Software development expenses increased to $89 million in 2017, from $76 million in 2016, and remained relatively consistent as a percentage of revenues at 9% for both 2017 and 2016. The increase in the amount of software development expense was primarily due to a $14 million increase in personnel costs to support enhancements and upgrades to our services and integration of the backend systems of the LoopNet and CoStar databases.

General and Administrative Expenses. General and administrative expenses increased 19% to $146 million in 2017, from $123 million in 2016, and remained relatively consistent as a percentage of revenues at 15% in 2017 and 2016. The increase in the amount of general and administrative expenses was primarily due to legal costs related to litigation of approximately $13 million, an increase in administrative personnel costs of $5 million to support the ongoing growth of the business, and a $3 million increase in charitable donations.

Customer Base Amortization Expense. Customer base amortization expense decreased to approximately $18 million in 2017, from $23 million in 2016, and decreased as a percentage of revenues to 2% in 2017, compared to 3% in 2016. The decrease in the amount and percentage of customer base amortization expense was primarily due to the accelerated amortization of acquired customer bases in 2016 as compared to 2017.

Interest and Other Income. Interest and other income increased to approximately $4 million in 2017, compared to approximately $2 million in 2016. The increase was primarily due to increased short term investments on a larger cash balance in 2017 than in 2016 mainly due to net proceeds of $834 million from the equity offering in October 2017.

Interest and Other Expense. Interest and other expense remained relatively consistent at $9 million in 2017 compared to $10 million in 2016. The decrease was primarily due to the repayment of outstanding debt in October 2017 in connection with the 2017 Credit Agreement, partially offset by higher interest rates on outstanding debt in 2017 compared to 2016.

Loss on Extinguishment. The loss on extinguishment was due to the restatement and amendment of the 2014 Credit Agreement as the 2017 Credit Agreement, which resulted in a loss on debt extinguishment of approximately $4 million.

Income Tax Expense. Income tax expense decreased to $42 million in 2017 compared to $52 million in 2016. Without the effect of discrete items, income tax expense would have increased by approximately $12 million. Discrete items resulted in a reduction in tax expense of approximately $22 million including the revaluation of the deferred tax liability at the lower federal statutory tax rate resulting in a $7 million benefit. We also recognized approximately $8 million benefit in net research and development tax benefits related to the periods 2013-2017. Finally, we recognized $7 million benefit from the impact of the accounting rule change in ASU 2016-09 that provided for recognizing excess tax benefits in income tax expense as compared to additional paid in capital, which was the treatment prior to 2017.

Comparison of Business Segment Results for Year Ended December 31, 2017 and Year Ended December 31, 2016

We manage our business geographically in two operating segments, with the primary areas of measurement and decision-making being North America, which includes the U.S. and Canada, and International, which includes the U.K., Spain, Germany and France. Management relies on an internal management reporting process that provides revenue and operating segment EBITDA. Management believes that operating segment EBITDA is an appropriate measure for evaluating the operational performance of our operating segments. EBITDA is used by management to internally measure operating and management performance and to evaluate the performance of the business. However, this measure should be considered in addition to, not as a substitute for or superior to, income from operations or other measures of financial performance prepared in accordance with GAAP. 

SegmentRevenues. North America revenues increased to $934 million for the year ended December 31, 2017, compared to $809 million for the year ended December 31, 2016. This increase in North America revenues was primarily due to increased revenues of approximately $55 million from our Multifamily products, and an increase of $55 million in CoStar Suite from the continued growth of our subscription-based services due to successful cross-selling of our services to our customers in existing markets, combined with continued high renewal rates. International revenues increased to $31 million for the year ended December 31, 2017, compared to $28 million for the year ended December 31, 2016. This increase was primarily due to continued growth of our subscription-based information services resulting from sales of CoStar Suite. 

Segment EBITDA. North America EBITDA increased to $237 million for the year ended December 31, 2017, compared to $211 million for the year ended December 31, 2016. The increase in North America EBITDA was due primarily to an increase in revenues of $125 million primarily offset by increased personnel costs from additional investments in our research operations and the opening of our Richmond research headquarters, as well as increased legal costs. International EBITDA decreased to $1 million for the year ended December 31, 2017, compared to $4 million for the year ended December 31, 2016. This decrease in International


EBITDA was primarily due to an increase in personnel costs from the relocation of our European research headquarters from Glasgow, Scotland to London, England and as a result of increased headcount from investments in our International research operations in Madrid, Spain and the U.K.

Liquidity and Capital Resources

Our principal sources of liquidity are cash and cash equivalents, cash from operations and the availability of funds from our revolving credit facility. Total cash and cash equivalents decreased to $1.1 billion at December 31, 2018 compared to cash and cash equivalents of $1.2 billion at December 31, 2017. The decrease in cash and cash equivalents for the year ended December 31, 2018 was primarily due to the cash paid, net of cash acquired in connection with the acquisitions of ForRent, Cozy and Realla of an aggregate of $418 million, as well as cash paid for purchases of property and equipment of $30 million and repurchases of restricted stock to satisfy employee tax withholding obligations upon vesting of restricted stock awards valued at approximately $24 million. These decreases wererevenue, partially offset by proceeds from the exerciseincreases in personnel, marketing and general and administrative costs. International EBITDA increased to income of employee stock options of approximately $27 million and cash generated from operations of $335 million.

Net cash provided by operating activities for the year ended December 31, 2018 was $335 million compared to $235$8 million for the year ended December 31, 2017 and $2012021 from a loss of $5 million for the year ended December 31, 2016.2020. The $100 million and $34 million


increases from December 31, 2017 to December 31, 2018 and from December 31, 2016 to December 31, 2017, respectively, are primarilyincrease was due to higher income from operations in both periods. Income from operations wasincreased revenue and lower general and administrative costs, partially offset by fluctuationsincreases in working capital.personnel and marketing costs.


Net cash usedFor a comparison of our business segment results of operations for the fiscal year ended December 31, 2020 to the year ended December 31, 2019, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations in investing activitiesour Annual Report on Form 10-K for the year ended December 31, 20182020, which was $448 million compared to $72 million forfiled with the year endedU.S. Securities and Exchange Commission on February 24, 2021.

Liquidity and Capital Resources

We believe the balance of cash, cash equivalents and restricted cash, which was $3.8 billion as of December 31, 2017.2021, along with cash generated by ongoing operations and continued access to capital markets, will be sufficient to satisfy the Company's cash requirements over the next 12 months and beyond. The $376Company’s material cash requirements include the following contractual and other obligations.

Debt. As of December 31, 2021, the Company had outstanding an aggregate principal amount of $1.0 billion of 2.800% Senior Notes due July 15, 2030. Future interest payments associated with the Senior Notes are $252 million, increase in investing activities in 2018 compared to 2017 was primarily due to approximately $418with $28 million cash paid, netpayable within 12 months.

Leases. The Company has lease arrangements for office facilities, data centers and certain vehicles. As of cash acquired, to acquire ForRent, Cozy and Realla during 2018, compared to $48December 31, 2021, the Company had fixed lease payment obligations of $134 million, cash paid to acquire Westside Rentals, LandWatch and The Screening Pros during 2017. During 2018, we incurred capital expenditures of approximatelywith $30 million comparedpayable within 12 months.

Purchase Obligations. The Company’s purchase obligations are associated with agreements that are enforceable and legally binding and that specify all significant terms, including fixed or minimum services to approximately $24 million during 2017.

The $49 million increase in investing activities in 2017 compared to 2016 was primarily due to $48 million cash paid to acquire Westside Rentals, LandWatch and The Screening Pros during 2017. During 2017, we incurred capital expenditures of approximately $24 million primarily related to computer equipment and leasehold improvements for build out of sales office space.payable within 12 months.

Net cash provided by financing activities for the year ended December 31, 2018 was $3 million compared to net cash provided by financing activities of $480 million for the year ended December 31, 2017 and $31 million in December 31, 2016. This $477 million decrease in financing activities in 2018 compared to 2017 and $449 million increase in financing activities in 2017 compared to 2016 was primarily due to $834 million in net proceeds from our equity offering, partially offset by an increase in debt repayments of $325 million in 2017.


Our future capital requirements will depend on many factors, including, among others, our operating results, expansion and integration efforts and our level of acquisition activity or other strategic transactions. To date, we have grown in part by acquiring other companies, and we expect to continue to make acquisitions. Any future

We currently plan to expand our Richmond, Virginia campus which may result in a material cash requirement in 2022 and beyond. We continue to assess financing options for the project.

Cash, cash equivalents and restricted cash for the year ended December 31, 2021 increased $71 million to $3.8 billion primarily due to cash generated from operations of $470 million and proceeds from the exercise of stock options and participation in our employee stock purchase plan of $18 million, partially offset by, cash paid for acquisitions may varyof $193 million, purchases of property and equipment and other intangibles of $189 million, including $123 million for the purchase of an office building and the underlying land located in sizeRichmond, Virginia and could be materialcorporate aircraft for $40 million, as well as, $33 million of repurchases of common stock from employees to our current operations. We may usesatisfy the employees' minimum tax withholding obligations upon the vesting of restricted stock grants.

Net cash stock, debt or other means of funding to make any future acquisitions.  

Based on current plans, we believe that our available cash combined with positive cash flow provided by operating activities should be sufficientfor the year ended December 31, 2021 was $470 million compared to fund$486 million for the year ended December 31, 2020. The $16 million decrease was due to a decrease in working capital of $141 million driven by payment of the $52 million termination fee pursuant to the Asset Purchase Agreement with RentPath in the first quarter of 2021, partially offset by an increase in net income excluding certain non-cash expenses such as depreciation and amortization and deferred income taxes. We expect to increase our investment in residential products in 2022 by approximately $200 million, which is expected to reduce our cash flow from operations for at least the next 12 months.

Contractual Obligations. The following table summarizes our principal contractual obligations at year ended December 31, 20182022.

Net cash used in investing activities for the year ended December 31, 2021 was $381 million compared to $464 million for the year ended December 31, 2020. The $83 million decrease in cash used in investing activities was primarily due to a decrease in cash paid for acquisitions of $233 million, partially offset by an increase in purchases of property, equipment and other assets which included $123 million for the purchase of an office building and the effect such obligations are expectedunderlying land located in Richmond, Virginia and corporate aircraft for $40 million, and proceeds from the sale of our ARS investments of $10 million received during 2020.

Critical Accounting Policies


The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. The following accounting policies involve a “critical accounting estimate” because they are particularly dependent on estimates and assumptions made by management about matters that are highly uncertain at the time the accounting estimates are made. In addition, while we have used our best estimates based on facts and circumstances available to us at the time, different acceptable assumptions would yield different results. Changes in the accounting estimates are reasonably likely to occur from period to period, which may have a material impact on the presentation of our financial condition and results of operations. We review these estimates and assumptions periodically and reflect the effects of revisions in the period that they are determined to be necessary. We consider policies relating to the following matters to be critical accounting policies:


Long-lived assets, intangible assets and goodwillgoodwill;
Income taxes;
Revenue recognitionrecognition; and
Income taxesBusiness combinations.
Business combinations


With respect to our accounting policy for long-lived assets, intangible assets and goodwill, we further supplement in Note 2 of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K with the following:


We assess the impairment of long-lived assets, identifiable intangibles and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Judgments made by management relate to the expected useful lives of long-lived assets and our ability to recover the carrying value of such assets. The accuracy of these judgments may be adversely affected by several factors, including the factors listed below:


Significant underperformance relative to historical or projected future operating results;
Significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
Significant negative industry or economic trends; or
Significant decline in our market capitalization relative to net book value for a sustained period.


When we determine that the carrying value of long-lived and identifiable intangible assets may not be recovered based upon the existence of one or more of the above indicators, we test for impairment.


Goodwill and identifiable intangible assets that are not subject to amortization are tested annually for impairment by each reporting unit on October 1 of each year and are also tested for impairment more frequently based upon the existence of one or more of the above indicators.


Goodwill represents the future economic benefits arising from a business combination and is calculated as the excess of costspurchase consideration paid in a business combination over the fair value of assets of acquired businesses.the net identifiable assets acquired. Goodwill is not amortized, but instead tested for impairment at least annually by each reporting unit. The Companyunit, or more frequently if an event or other circumstance indicates that the fair value of a reporting unit may be below its carrying amount. We may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or elect to bypass such assessment. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, or the Company electswe elect to bypass such assessment, the Companywe then determinesdetermine the fair value of each reporting unit. We estimate the fair value of each reporting unit based on a projected discounted cash flow model that includes significant assumptions and estimates including our discount rate, growth rate and future financial performance. Assumptions about the discount rate are based on a weighted average cost of capital for comparable companies.companies and determined by management to be commensurate with the risk in our current business model. Assumptions about the growth rate and future financial performance of a reporting unit are based on our forecasts, business plans, economic projections and anticipated future cash flows. These assumptions are subject to change from period to period and could be adversely impacted by the uncertainty surrounding global market conditions, commercial real estate conditions and the competitive environment in which we operate. Changes in these or other factors could negatively affect our reporting units' fair value and potentially result in impairment charges. Such impairment charges could have an adverse effect on our results of operations.

The fair value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an impairment loss is recognized for the difference. We estimate

45


As of October 1, 2021, we performed an assessment of the relevant qualitative factors for our North America and International reporting units and concluded that it was not more likely than not that the fair value of oureach reporting units based on a projected discounted cash flow method using a discount rate determined by our management to be commensurate with the risk in our current business model. As of October 1, 2017, the date of our most recent impairment analysis, the estimated fair value of each of our reporting units substantially exceeded theunit was less than its respective carrying value of our reporting units.amounts. There have been no events or changes in circumstances as a result of our qualitative impairment analysis on October 1, 2018,2021, that would indicate that the carrying value of each reporting unit may not be recoverable.




For an in depthin-depth discussion of each of our significant accounting policies, including our critical accounting policies and further information regarding estimates and assumptions involved in their application, see Note 2 to the accompanying consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

We provide information, analytics and online marketplace services to the commercial real estate and related business community incommunities within the U.S., the U.K.,regions where we operate which primarily include, North America, Europe, Asia-Pacific and parts of Canada, Spain, Germany and France. OurLatin America. The functional currency for a majority of our operations in the U.K., Canada, Spain, Germany and France is the local currency. As such, fluctuationscurrency, with the exception of certain international locations for which the functional currency is the British Pound.

Fluctuations in the British Pound, Canadian dollar and Euro may have an impact on our business, results of operations and financial position. For the yearyears ended December 31, 2018,2021 and December 31, 2020, revenues denominated in foreign currencies waswere approximately 3%4% and 5%, respectively, of total revenue. For the yearyears ended December 31, 2018,2021 and December 31, 2020, our revenues would have decreased by approximately $3$7 million and $8 million, respectively, if the U.S. dollar exchange rate used strengthened by 10%. For the yearyears ended December 31, 2018,2021 and December 31, 2020, our revenues would have increased by approximately $3$7 million and $8 million, respectively, if the U.S. dollar exchange rate used weakened by 10%. Fluctuations in the exchange rates of revenues denominated in any other foreign currencies would have had an immaterial impact on our consolidated results. In addition, we have assets and liabilities denominated in foreign currencies. We currently do not use financial instruments to hedge our exposure to exchange rate fluctuations with respect to our foreign subsidiaries. We may seek to enter into hedging transactions in the future to reduce our exposure to exchange rate fluctuations, but we may be unable to enter into hedging transactions successfully, on acceptable terms or at all. As of December 31, 2018,2021, accumulated other comprehensive loss included a loss from foreign currency translation adjustments of approximately $11$5.8 million.


We do not believe we have material exposure to market risks associated with changes in interest rates related to cash equivalent securities held as of December 31, 2018.2021. As of December 31, 2018,2021, we had $1.1$3.8 billion of cash, cash equivalents and cash equivalents.restricted cash. If there is an increase or decrease in interest rates, there will be a corresponding increase or decrease in the amount of interest earned on our cash and cash equivalents.

Included within our short-term and long-term investments are investments in mostly AAA-rated student loan ARS. These securities are primarily securities supported by guarantees from the FFELP of the U.S. Department of Education. As of December 31, 2018, $11 million of our investments in ARS failed to settle at auction. As a result, we may not be able to sell these investments at par value until a future auction on these investments is successful. In the event we need to immediately liquidate these investments, we may have to locate a buyer outside the auction process, who may be unwilling to purchase the investments at par, resulting in a loss. If the issuers are unable to successfully close future auctions and/or their credit ratings deteriorate, we may be required to adjust the carrying value of these investments as a temporary impairment and recognize a greater unrealized loss in accumulated other comprehensive loss or as an other-than-temporary impairment charge to earnings. Based on our ability to access We currently diversify our cash and cash equivalents holdings amongst multiple financial institutions.

We are subject to interest rate market risk in connection with our new revolving credit facility. On July 1, 2020, we entered into the 2020 Credit Agreement, which provides for variable rate borrowings of up to $750 million. On July 1, 2020, we issued $1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030. Changes in interest rates would not have a material impact to our current interest and debt financing expense, as all of our expected operating cash flows, we do not anticipate having to sell these securities below par value in order to operateborrowings except for our business in the foreseeable future.credit facility are fixed rate, and no amounts were outstanding under our credit facility as of December 31, 2021.

As of December 31, 2018,2021, we believe our intangible assets will be recoverable,recoverable; however, changes in the economy, the business in which we operate and our own relative performance could change the assumptions used to evaluate intangible asset recoverability. In the event that we determine that an asset has been impaired, we would recognize an impairment charge equal to the amount by which the carrying amount of the assets exceeds the fair value of the asset. We continue to monitor these assumptions and their effect on the estimated recoverability of our intangible assets.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934 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 Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.


As of December 31, 2018,2021, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures.procedures as of the end of the fiscal year. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2021 and were operating at a reasonable assurance level.


During 2018, we continuedWe continue to implement a new financial system that is designed to improve the efficiency and effectiveness of our operational and financial accounting processes. This implementation is expected to continue through 2019.beyond 2022. Consistent with any process change that we implement, the design of the internal controls has and will continue to be evaluated for effectiveness as part of our overall assessment of the effectiveness of our disclosure controls and procedures. We expect that the implementation of this system will improve our internal controls over financial reporting.


Other than the implementation of a new financial system noted above, there have been no changes in our internal control over financial reporting during our most recent fiscal yearthe quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We continue to monitor and assess the effects of the COVID-19 pandemic and our response to the pandemic on our internal controls so we can take appropriate actions to minimize any impact on the design and operating effectiveness.
 
Management’s Report on Internal Control over Financial Reporting


Management of CoStar Group is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. As defined by the Securities and Exchange Commission, internal control over financial reporting is a process designed by, or supervised by, the Company’s principal executive and principal financial officers, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP.


The Company’s internal control over financial reporting is supported by written 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 Company’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of the Company’s management and directors; 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. 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.

In connection with the preparation of the Company's annual financial statements, management of the Company has undertaken an assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 20182021 based on criteria established in Internal Control – Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“the COSO Framework”). Management's assessment included an evaluation of the


design of the Company's internal control over financial reporting and testing of the operational effectiveness of the Company's internal control over financial reporting.


Based on this assessment, management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2018.2021.


Ernst & Young LLP, the independent registered public accounting firm that audited the Company's financial statements included in this report, has issued an attestation report on the effectiveness of internal control over financial reporting, a copy of which is included in this Annual Report on Form 10-K.


On February 21, 2018,May 24, 2021 and October 1, 2021 we completed the acquisitionacquisitions of ForRent. On October 12, 2018, we completed the acquisition of Realla Ltd. On November 8, 2018, we completed the acquisition of Cozy Services, Ltd.Homes Group, LLC ("Homes.com") and Comreal Info SAS ("BureauxLocaux"), respectively. As permitted by the Securities and Exchange Commission, we have elected to exclude the internal controls of these acquisitions that have not been integrated into our existing processes and controls from our assessment of the effectiveness of internal control over financial reporting as of December 31, 2018.2021. The excluded aggregate financial position of ForRent, Realla Ltd.Homes.com and Cozy Ltd.BureauxLocaux collectively represented less than 1% of our total assets as of December 31, 2018,2021, and less than 4%1% of our revenues and total operating costs for the year then ended. We will include the internal controls of ForRent, Realla Ltd.Homes.com and Cozy Services, Ltd.BureauxLocaux in our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2019.2022.

Report of Independent Registered Public Accounting Firm


The Board of Directors and Stockholders of CoStar Group, Inc.


Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. (the Company) as of December 31, 20182021 and 2017, and2020, the related consolidated statements of operations, comprehensive income, (loss), stockholders'changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2018,2021, and the related notes and the financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “financial“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company at December 31, 20182021 and 2017,2020, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2018,2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018,2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report datedFebruary 28, 201923, 2022 expressed an unqualified opinion thereon.
Adoption of ASU No. 2014-09
As discussed in Note 2 to the consolidated financial statements, the Company changed its method for recognizing revenue in 2018 due to the adoption of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), and the related amendments.
Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’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 Matter


The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of Acquired Intangible Assets of Homes.com
Description of the Matter
As described in Note 5 to the consolidated financial statements, during the year ended December 31, 2021, the Company completed the acquisition of Homes Group, LLC. (“Homes.com”) for $152 million in cash. The Company’s accounting for the acquisition included determining the fair value of the acquired intangible assets, with customer base ($32 million) and trade names ($21 million) comprising most of the assets acquired.

Auditing the accounting for the acquired intangible assets of Homes.com involved complex auditor judgment due to the estimation required in management’s determination of the fair value. The estimation was significant primarily due to the sensitivity of the fair value to the underlying assumptions, including customer attrition rates and projected revenue. Prospective financial information used in determining the fair value of customer base and trade name intangible assets could be affected by changes in economic and market conditions.

How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process for accounting for acquired intangible assets. For example, we tested controls over management’s review of the valuation model and significant assumptions used in the valuation as well as controls over the completeness and accuracy of the data used in the model and assumptions.


To test the fair value of these acquired intangible assets, our audit procedures included, among others, evaluating the Company's use of valuation methodologies, evaluating the significant assumptions, evaluating the prospective financial information and testing the completeness and accuracy of underlying data. We involved our valuation specialists to assist in testing certain significant assumptions used to value the acquired intangible assets. For example, we compared the significant assumptions to current industry and market trends, historical results of the acquired business and to other relevant factors. We also performed sensitivity analyses of the significant assumptions to evaluate the change in the fair value resulting from changes in the assumptions.

We have served as the Company’s auditor since 1994.

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.

See Note 5 for further discussion of these acquisitions.


2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation


The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Accounting policies are consistent for each operating segment.


Use of Estimates


The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to revenue recognition, allowance for doubtful accounts,credit losses, the useful lives and recoverability of property and equipmentlong-lived and intangible assets, recoverability of long-lived assets and intangible assets with definite lives, goodwill, income taxes, fair value of equity instruments, fair value of auction rate securities (“ARS”), accounting for business combinations, stock-based compensation, estimating the Company's incremental borrowing rate for its leases, and contingencies, among others. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenues and expenses. Actual results could differ from these estimates.


Revenue Recognition

Subsequent to the Adoption of Accounting Standards Update (“ASU") 2014-09, Revenue from Contracts with Customers, later codified as Accounting Standards Codification 606 ("ASC 606"), on January 1, 2018


The Company derives revenues primarily by (i) providing access to its proprietary database of commercial real estate information and (ii) providing online marketplaces for professional property management companies, property owners, real estate agents and brokers and landlords, in each case, typically through a fixed monthly fee for its subscription-based services. The Company's subscription-based services consist primarily of information, analyticsOther subscription based-services include (i) real estate and online marketplace services offered over the Internetlease management solutions to commercial customers, real estate investors and lenders, (ii) access to applications to manage workflow and advertising and marketing services for residential real estate agents through our acquisitions of Homes.com, which was acquired in May 2021, and Homesnap, which was acquired in December 2020, (iii) benchmarking and analytics for the hospitality industry and related professionals. (iv) market research, portfolio and debt analysis, management and reporting capabilities. See Note 5 for further discussion of acquisitions.

COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Subscription contract rates are based on the number of sites, number of users, organization size, the client’s business focus, geography, the number and types of services to which a client subscribes, the number of properties a client advertises and the prominence and placement of a client's advertised properties in the search results. A majority of theThe Company’s subscription-based license agreements typically renew automatically, and a majority have a term of at least one yearyear.

The Company also derives revenues from transaction-based services including: (i) an online auction platform for commercial real estate through Ten-X, which was acquired in June 2020, (ii) providing online tenant applications, including background and renew automatically.credit checks, and rental payment processing and (iii) complementary services on an ad hoc basis for our (a) real estate and lease management solutions to commercial customers, real estate investors and lenders, (b) benchmarking and analytics for the hospitality industry and (c) other service offerings.


The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers, (ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract transaction price to the performance obligations and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation(s).obligations.


The Company recognizes revenues upon the satisfaction of its performance obligation(s) (upon transfer of control of promised services to its customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those services. Revenues from subscription-based services are recognized on a straight-line basis over the term of the agreement. Revenues from transaction-based services are recognized when the promised product or services are delivered, which, in the case of Ten-X auctions, is at the time of a successful closing for the sale of the property.


TheIn limited circumstances, the Company's contracts with customers often include promises to transfer multiple services, such as contracts for its subscription-based services and professional services. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. Determining whether services are considered distinct, performance obligations may require significant judgment. Judgment is required to determinewhich involves the determination of the standalone selling price (“SSP”)

for each distinct performance obligation. In instances where SSP is not directly observable, such as when the Company does not sell the services separately, the Company determines the SSP using available information, including market conditions and other observable inputs.


Deferred revenue results from amounts billed in advance to customers or cash received from customers in advance of the saleCompany's fulfillment of subscription licensesits performance obligation(s) and is recognized over the term of the license agreement.as those obligations are satisfied.


Contract assets represent a conditional right to consideration for satisfied performance obligations that become a receivable when the conditions are satisfied. Contract assets are generated when contractual billing schedules differ from revenue recognition timing.


Certain sales commissions are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions incurred for obtaining new contracts are deferred and then amortized as selling and marketing expenses on a straight-line basis over a period of benefit that the Company has determined to be three years. The three-year amortization period was determined based on several factors, including the nature of the technology and proprietary data underlying the services being purchased, customer contract renewal rates and industry competition. Certain commission costs are not capitalized as they do not represent incremental costs of obtaining a contract.

See Note 3 for further discussion on the impact of the adoption of ASC 606.Company's revenue recognition.

For details about the Company’s revenue recognition policy prior to the adoption of ASC 606, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission on February 23, 2018.


Cost of Revenues


Cost of revenues principally consists of salaries, benefits, bonuses and stock-based compensation expenses and other indirect costs for the Company’sCompany's researchers who collect and analyze the commercial real estate data that is the basis for the Company’sCompany's information, analytics and online marketplaces.marketplaces and for employees that support these products. Additionally, cost of revenues includes the cost of data from third-party data sources and costs related to advertising purchased on behalf of customers, credit card and other transaction fees relating to processing customer transactions, which are expensed as incurred, and the amortization of acquired trade names, technology and certain other intangible assets.

Income Taxes


Deferred income taxes result from temporary differences between the tax basis of assets and liabilities and the basis reported in the Company’s consolidated financial statements. Deferred tax liabilities and assets are determined based on the difference between the financial statement and the tax basis of assets and liabilities using enacted rates in effect during the year in which the Company expects differences to reverse. Valuation allowances are provided against assets, including net operating losses, if the Company determines it is more likely than not that some portion or all of an asset may not be realized. Interest and penalties related to income tax matters are recognized in income tax expense.

If the Company's initial estimates of the achievement of the performance conditions change, the related stock-based compensation expense and timing of recognition may fluctuate from period to period based on those estimates. If the performance conditions are not met, no stock-based compensation expense will be recognized and any previously recognized stock-based compensation expense will be reversed. For equity instruments that vest based onawards with both a performance condition and a market condition, the Company estimates the fair value of each equity instrument granted on the date of grant using a Monte-Carlo simulation model. This pricing model uses multiple simulations to evaluate the probability of achieving the market condition to calculate the fair value of the awards. Stock-based compensation expense is updated based on the expected achievement of the related performance conditions at the end of each reporting period. If the performance conditions are not met, no stock-based compensation expense will be recognized, and any previously recognized stock-based compensation expense will be reversed.

The Company determines the appropriate classification of debt and equity investments at the time of purchase and re-evaluates such designation as of each balance sheet date. The Company's investments consist of long-term variable rate debt instruments with an auction reset feature, referred to as auction rate securities, and are classified as available-for-sale. The Company's auction rate security investments are carried at fair value and any changes in unrealized holding gains and losses, net of the related tax effect, are excluded from earnings and are reported as a separate component of accumulated other comprehensive loss in stockholders’ equity until realized. A decline in market value of any investment below cost that is deemed to be other-than-temporary results in a reduction in carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. Dividend and interest income are recognized when earned.

Concentration of Credit Risk and Financial Instruments


The Company performs ongoing assessments of its customers’ financial conditions and generally does not require that its customers’ obligations to the Company be secured. The Company maintains reserves for doubtful accounts, which have historically been immaterial to the Company's consolidated financial statements. Further, the large size of the Company’s customer base creates a lack of dependence on any individual customer that mitigates the risk of nonpayment of the Company’s accounts receivable. No single customer accounted for more than 5% of the Company’s revenues for each of the years ended December 31, 2018, 2017,2021, 2020 and 2016.2019. The carrying amount of the accounts receivable approximates the net realizable value.


The Company holds cash at major financial institutions that often exceed Federal Deposit Insurance Corporation insured limits. The Company manages its credit risk associated with cash concentrations by concentrating itsdiversifying cash deposits inholdings across AAA rated Government and Treasury Money Market Funds and multiple high quality financial institutions, and by periodically evaluating the credit quality of the primary financial institutions holding such deposits. The carrying value of cash approximates fair value. Historically, the Company has not experienced any losses due to such cash concentrations.


Accounts Receivable, Net of Allowance for Doubtful AccountsCredit Losses


Accounts receivable are recorded at the invoiced amount net of credits due. Accounts receivable payment terms vary and amounts due from customers are stated in the financial statements net ofThe Company maintains an allowance for doubtful accounts. When evaluatingcredit losses to cover its current expected credit losses ("CECL") on its trade receivables and contract assets arising from the adequacyfailure of customers to make contractual payments. The Company estimates credit losses expected over the allowance for doubtful accounts, the Company analyzeslife of its trade receivables and contract assets based on historical collection experience, changes in customer payment profiles and the aging of receivable balances, as well asinformation combined with current economic conditions all of whichthat may affect a customer’s ability to pay. pay and reasonable and supportable forecasts. While the Company uses various credit quality metrics, it primarily monitors collectability by reviewing the duration of collection pursuits on its delinquent trade receivables and historical write off trends. Based on the Company’s experience, the customer's delinquency status, which is analyzed periodically, is the strongest indicator of the credit quality of the underlying trade receivables. The Company’s policy is to write-off trade receivables when they are deemed uncollectible. A majority of the Company's trade receivables are less than 365 days outstanding.


Under the CECL impairment model, the Company develops and documents its allowance for credit losses on its trade receivables based on 5 portfolio segments. The determination of portfolio segments is based primarily on the qualitative consideration of the nature of the Company’s business operations and the characteristics of the underlying trade receivables, as follows:

CoStar Portfolio Segment - The CoStar portfolio segment consists of 2 classes of trade receivables based on geographical location: North America and International.

Information Services Portfolio Segment - The Information Services portfolio segment consists of 4 classes of trade receivables: CoStar Real Estate Manager; Information Services, North America; STR, US; and STR, International.

Multifamily Portfolio Segment - The Multifamily portfolio segment consists of 1 class of trade receivables.

LoopNet Portfolio Segment - The LoopNet portfolio segment consists of one class of trade receivables.

Other Marketplaces Portfolio Segment - The Other Marketplaces portfolio segment consists of two classes of trade receivables: Ten-X and other marketplaces.

The majority of Residential revenue is e-commerce based and does not result in accounts receivable. Residential accounts receivable and the related allowance for credit losses are not material.

Leases

The determination of whether an arrangement contains a lease and the classification of a lease, if applicable, is made at the commencement of the arrangement, at which time the Company also measures and recognizes a right-of-use ("ROU") asset, representing the Company’s right to use the underlying asset, and a lease liability, representing the Company’s obligation to make lease payments under the terms of the arrangement. For the purposes of recognizing ROU assets and lease liabilities associated with the Company’s leases, the Company has elected the practical expedient to not recognize a ROU asset or lease liability for short-term leases, which are leases with a term of twelve months or less. The lease term is defined as the noncancelable portion of the lease term, plus any periods covered by an option to extend the lease if it is reasonably certain that that the option will be exercised.

In determining the amount of lease payments used in measuring ROU assets and lease liabilities, the Company has elected the practical expedient not to separate non-lease components from lease components for all classes of underlying assets. Consideration deemed part of the lease payments used to measure ROU assets and lease liabilities generally includes fixed payments and variable payments based on either an index or a rate, offset by lease incentives. Upon commencement, the initial ROU asset also includes any lease prepayments. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The rates implicit within the Company's leases are generally not determinable. Therefore, the Company's incremental borrowing rate is used to determine the present value of lease payments. The determination of the Company’s incremental borrowing rate requires judgment and is determined at lease commencement, or as of January 1, 2019 for operating leases in existence upon adoption of the new lease standard. The incremental borrowing rate is subsequently reassessed upon a modification to the lease arrangement.

Lease costs related to the Company's operating leases are generally recognized as a single ratable lease cost over the lease term.

See Note 7 for further discussion of the Company’s accounting for leases.

Property and Equipment, Net


Property and equipment are stated at cost, net of accumulated depreciation and amortization. All repairs and maintenance costs are expensed as incurred. Costs related to acquisition of additional aircraft components or the replacement of existing aircraft components are capitalized and depreciated over the estimated useful life of the aircraft or the added or replaced component, whichever is less. Depreciation and amortization are calculated on a straight-line basis over the following estimated useful lives of the assets:


Leasehold improvementsBuildingsShorter of lease term or useful life
Twenty to thirty-nine years
LandIndefinite
Aircrafts
Ten to twenty years
Furniture and office equipment
Five to ten years
VehiclesFive to ten years
VehiclesFive to ten years
Computer hardware and software
Three to five years
Leasehold improvementsShorter of lease terms or useful life

Qualifying internal-use software costs incurred during the application development stage, which consist primarily of internal product development costs, outside services and purchased software license costs are capitalized and amortized over the estimated useful life of the asset. All other costs are expensed as incurred. In the fourth quarter of 2021, the Company began removing fully depreciated property and equipment from the cost and accumulated depreciation amounts disclosed.


Long-Lived Assets, Intangible Assets and Goodwill

Long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.

GoodwillAcquired technology and Intangible Assetsdata, customer base assets, trade names and other intangible assets are related to the Company’s acquisitions. Acquired technology and data is amortized on a straight-line basis over periods ranging from one year to eight years. Acquired intangible assets characterized as customer base assets consist of acquired customer contracts and the related customer relationships and are amortized over periods ranging from five years to thirteen years. Acquired customer bases are amortized on an accelerated or straight-line basis depending on the expected economic benefit of the intangible asset. Acquired trade names and other intangible assets are amortized on a straight-line basis over periods ranging from one year to fifteen years. In the fourth quarter of 2021, the Company began removing fully amortized intangible assets from the cost and accumulated amortization amounts disclosed.


Goodwill represents the future economic benefits arising from a business combination and is calculated as the excess of the purchase consideration paid in a business combination over the fair value of the net identifiable assets acquired. Goodwill is not amortized, but instead is assigned to each of the Company's reporting units and tested for impairment at least annually, on October 1, or when events and circumstances indicatemore frequently if an event or other circumstance indicates that the fair value of a reporting unit may be below its carrying value. The Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or elect to bypass such assessment.amount. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, or the Company elects to bypass such assessment, the Company performs a quantitative test that requires the determination ofthen determines the fair value of each reporting unit. The estimate of the fair value of each reporting unit is based on a projected discounted cash flow model that includes significant assumptions and estimates including the discount rate, growth rate and future financial performance. Assumptions about the discount rate are based on a weighted average cost of capital for comparable companies. Assumptions about the growth rate and future financial performance of a reporting unit are based on the Company's forecasts, business plans, economic projections and anticipated future cash flows. The fair value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an impairment loss is recognized for the difference.


Acquired technology, trade namesSee Notes 5, 9 and other10 for further discussion of acquisitions, goodwill and intangible assets, and customer base assets are related to the Company’s acquisitions (see Notes 8 and 9). Acquired technology is amortized on a straight-line basis over periods ranging from two years to eight years. Acquired trade names and other intangible assets are amortized on a straight-line basis over periods ranging from one year to fifteen years. Acquired intangible assets characterized as customer base assets consist of acquired customer contracts and the related customer relationships and are amortized over periods ranging from five years to thirteen years. Acquired customer bases are amortized on an accelerated or straight-line basis depending on the expected economic benefit of the intangible asset.respectively. 

Long-Lived Assets

Long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet.


Debt Issuance Costs


Costs incurred in connection with the issuance of long-term debt are deferred and amortized as interest expense over the term of the related debt using the effective interest method for term debt and on a straight-line basis for revolving debt. ToThe Company made a policy election to classify deferred issuance costs on the extent that debt is outstanding, these amounts are reflected in therevolving credit facility as a long-term asset on its consolidated balance sheets as direct deductions from a combination of the current and long-term portions of debt for term debt and as current and long-term assets for costs related to revolving debt.sheets. Upon a refinancing or amendment, previously capitalized debt issuance costs are expensed and included in loss on extinguishment of debt if the Company determines that there has been a substantial modification of the related debt. If the Company determines that there has not been a substantial modification of the related debt, any previously capitalized debt issuance costs are amortized as interest expense over the term of the new debt instrument.

Business Combinations


The Company allocates the purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The purchase price is determined based on the fair value of the assets transferred, liabilities incurredassumed and equity interests issued, after considering any transactions that are separate from the business combination. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to makeThe Company applies significant assumptions, estimates and assumptions,judgments in determining the fair value of assets acquired and liabilities assumed on the acquisition date, especially with respect to intangible assets and contingent liabilities.

discount rates. Any adjustments to provisional amounts that are identified during the measurement period are recorded in the reporting period in which the adjustment amounts are determined. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.


For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether the Company includes these contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.


If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period, which is generally the case given the nature of such matters, the Company will recognize an

asset or a liability for such pre-acquisition contingency if: (i) it is probable that an asset existed or a liability had been assumed at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement period, changes in the Company's estimates of such contingencies will affect earnings and could have a material effect on its results of operations and financial position.


In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items based upon facts and circumstances that existed as of the acquisition date, with any adjustments to its preliminary estimates being recorded to goodwill provided that the Company is within the measurement period. Subsequent to the measurement period, changes to these uncertain tax positions and tax related valuation allowances will affect the Company's provision for income taxes in its consolidated statements of operations and comprehensive income and could have a material impact on its results of operations and financial position.

6.    INVESTMENTS AND FAIR VALUE MEASUREMENTS


Fair value is defined as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. There is a three-tier fair value hierarchy, which categorizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.


The following table represents the Company's fair value hierarchy for its financial assets (cashcomprise Level 1 cash equivalents with original maturities of three months or less in the amount of $3.0 billion and investments)$3.4 billion as of December 31, 2021 and December 31, 2020, respectively.

ARS are variable rate debt instruments whose interest rates are reset approximately every 28 days. The underlying securities have contractual maturities greater than twenty years. The ARS are recorded at fair value.

As of December 31, 2018, the Company held ARS with $11 million par value, all of which failed to settle at auction. The majority of these investments are of high credit quality and are primarily student loan securities supported by guarantees from the FFELP of the U.S. Department of Education. The Company may not be able to liquidate and fully recover the carrying value of the ARS in the near term. As a result, these securities are classified as long-term investments in the Company’s consolidated balance sheet as of December 31, 2018. See Note 5 for further discussion of the scheduled maturities of investments classified as available-for-sale. 

While the Company continues to earn interest on its ARS investments at the contractual rate, these investments are not currently actively trading and therefore do not currently have a readily determinable market value. The estimated fair value of the ARS no longer approximates par value. The Company used a discounted cash flow model to determine the estimated fair value of its investment in ARS as of December 31, 2018. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of contractual cash flows, liquidity risk premiums, expected holding periods and default risk. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the assumptions used in the model and settlements of ARS investments that occurred during the period.
The only significant unobservable input in the discounted cash flow model is the discount rate. The discount rate used represents the Company's estimate of the yield expected by a market participant from the ARS investments. The weighted average discount rate used in the discounted cash flow models as of December 31, 2018 and 2017 was approximately 6%. Selecting another discount rate within the range used in the discounted cash flow model would not result in a significant change to the fair value of the ARS.

Based on this assessment of fair value, as of December 31, 2018, the Company determined there was no decline in the fair value of its ARS investments. In addition, the ARS are of high credit quality, if the issuers are unable to successfully close future auctions and/or their credit ratings deteriorate, the Company may be required to record additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments.

Senior Notes

On October 19, 2017,July 1, 2020, the Company issued $1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030 (the “Senior Notes”). The Senior Notes were sold to a group of financial institutions as initial purchasers who subsequently resold the Senior Notes to non-U.S. persons pursuant to Regulation S under the Securities Act of 1933, as amended (the “Securities Act”), and to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act at a purchase price equal to 99.921% of their principal amount. Interest on the Senior Notes is payable semi-annually in arrears beginning on January 15, 2021. The Senior Notes may be redeemed in whole or in part by the Company (a) at any time prior to April 15, 2030 at a redemption price equal to 100% of the principal amount of the Senior Notes, plus the Applicable Premium (as calculated in accordance with the indenture governing the Senior Notes), and any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, but excluding, the redemption date, and (b) on or after April 15, 2030 at a redemption price equal to 100% of the principal amount of the Senior Notes, plus any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, but excluding, the redemption date. The Company’s obligations under the Senior Notes are guaranteed on a senior, unsecured basis by the Company’s domestic wholly owned subsidiaries and contain covenants, events of default and other customary provisions for which the Company was in compliance with as of December 31, 2021.

Revolving Credit Facility

On July 1, 2020, the Company also entered into ana second amended and restated credit agreement (the ‘‘2017"2020 Credit Agreement’’Agreement"), which amended and restated in its entirety the then-existing credit agreement datedoriginally entered into on April 1, 2014 and amended and restated on October 19, 2017 (the "2014“2017 Credit Agreement"Agreement”). The 20172020 Credit Agreement provides for a $750 million revolving credit facility with a term of five years (maturing July 1, 2025) and a letter of credit sublimit of $20 million from a syndicate of financial institutions as lenders and issuing banks. The 2017A commitment fee of 0.25% to 0.30% per annum, depending on the Total Leverage Ratio (defined in 2020 Credit Agreement), is payable quarterly in arrears based on the unused revolving commitment.

Subject to certain conditions, on no more than 5 occasions, the Company may request increases in the amount of revolving commitments and/or the establishment of term commitments under the 2020 Credit Agreement. Borrowings under the 2020 Credit Agreement will bear interest at a floating rate which can be, at the Company’s option, either (a) an alternate base rate plus an applicable rate ranging from 0.50% to 1.25% or (b) a LIBOR or EURIBOR (with a floor of 0.0%) for the specified interest period plus an applicable rate ranging from 1.50% to 2.25%, in each case depending on the Company's Total Leverage Ratio (as defined in the 2020 Credit Agreement). As LIBOR may not always be available to the Company as a base interest rate for borrowings under the credit facility, the 2020 Credit Agreement allows the Company and the administrative agent under the 2020 Credit Agreement to amend the 2020 Credit Agreement to replace LIBOR with one or more Secured Overnight Financing Rate (“SOFR”) based rates or another alternative benchmark rate. Funds drawn down on the revolving credit facility pursuant to the 2020 Credit Agreement may be used for working capital and other general corporate purposes of the Company and its restricted subsidiaries. In connection with the transaction, the Company incurred $4 million of issuance costs. Those costs along with the $4 million of unamortized costs related to the prior agreement were allocated between the extinguishment of the 2014 Credit Agreement and the 2017 Credit Agreement. This allocation resulted in the Company recognizing a loss of $4 million on the extinguishment with the remaining $4 million being deferred and amortized on a straight-line basis as interest expense over the term of the 2017 Credit Agreement.

Up to $20 million of the revolving credit facility is available for the issuance of letters of credit. The Company had an irrevocable standby letter of credit outstanding totaling $0.2 million as of December 31, 2018 and December 31, 2017, which was required to secure its San Francisco office lease. The letter of credit was established in 2014 and automatically renews through January 31, 2025.

The loans under the 2017 Credit Agreement bear interest during any interest period selected by the Company, at either (i) the London interbank offered rate for deposits in U.S. dollars with a maturity comparable to such interest period, adjusted for statutory reserves (“LIBOR”), plus an initial spread of 1.25% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio (as defined in the 2017 Credit Agreement) of the Company, or (ii) at the greatest of (x) the prime rate from time to time announced by JPMorgan Chase Bank, N.A., (y) the federal funds effective rate plus half of 1% and (z) LIBOR for a one-month interest period plus 1.00%, plus an initial spread of 0.25% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio of the Company. If an event of default occurs under the 2017 Credit Agreement, the interest rate on overdue amounts will increase by 2.00% per annum. The obligations under the 20172020 Credit Agreement are guaranteed by all material subsidiarieseach of the CompanyCompany’s current and are secured by a lien on substantially all of the assets of the Company and its materialfuture direct or indirect wholly owned restricted domestic subsidiaries, other than certain excluded subsidiaries, in each case subject to certain exceptions, pursuant to security and guarantee agreements entered into on the closing date of the 2017 Credit Agreement.agreements.

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Act”), which significantly changed U.S. tax law. The Tax Act lowered the Company’s U.S. statutory federal income tax rate from 35% to 21% effective January 1, 2018, while also imposing a deemed repatriation tax on deferred foreign income. The Tax Act also created a new minimum tax on certain future foreign earnings under section 951(a) and allows foreign-derived intangible income deduction under section 250(a). The Securities and Exchange Commission staff issued Staff Accounting Bulletin 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, ("SAB 118"), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provided a measurement period of up to one year from the Tax Act enactment date for companies to complete the accounting under ASC 740.

As of December 31, 2018, the Company's accounting for income tax effects of the Tax Act is complete and the Company has reflected all income tax effects of the Tax Act in the financial statements and related disclosures. Any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, may result in the Company deciding to make adjustments. Those adjustments may materially impact the provision for income taxes in the period in which the adjustments are made.

As of December 31, 2018 the Company has evaluated the global intangible low taxed income inclusion under section 951(a)("GILTI"). Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into the measurement of deferred taxes (the “deferred method”). The Company elected to record the GILTI income inclusion under the current-period cost method.

In some cases, vesting of restricted stock awards under the 2007 Plan is subject to performance conditions. Upon the occurrence of a Change of Control, as defined in the 2007 Plan, all outstanding unexercisable options and restricted stock grants under the 2007 Plan immediately become exercisable.


The 2016 Plan provides for the grant of stock options, restricted stock, restricted stock units and stock appreciation rights to officers, directors and employees of the Company and its subsidiaries. Stock options granted under the 2016 Plan may be non-qualified or may qualify as incentive stock options. Except in limited circumstances related to a merger or other acquisition, the exercise price for an option may not be less than the fair market value of the Company’s common stock on the date of grant. The vesting period for each grant of options, restricted stock, restricted stock units and stock appreciation rights under the 2016 Plan is determined by the Board of Directors or a committee thereof and is generally three to four years, subject to minimum vesting periods for restricted stock and restricted stock units of at least one year. In some cases, vesting of awards under the 2016 Plan may be based on performance conditions. The Company has issued and/orinitially reserved the followingapproximately 22.7 million shares of common stock for issuance under the 2016 Plan: (a) 1,450,000 shares of common stock, plus (b) 815,464Plan, which included shares of common stock that were authorized for issuance under the 2007 Plan that, as of June 9, 2016,and remained available for issuance under the 2007 Plan (not including any Shares that were subject as of such date to outstanding awards under the 2007 Plan), and (c) anyJune 9, 2016.

Pursuant to the terms of the 2016 Plan, all amounts reserved or issued under the plan were adjusted to reflect the Company’s 10-for-one common stock split. Unless terminated sooner, the 2016 Plan will terminate in June 2026, but will continue to govern unexercised and unexpired awards issued under the 2016 Plan prior to that date. Approximately 215.3 million shares were available for future grant under the 2016 Plan as of December 31, 2018.2021.

Restricted Stock Awards


In February 2018, March 2017 and March 2016, theThe Compensation Committee of the Board of Directors of the Company historically approved grants of restricted common stock to employees and directors of the Company that vest over a specific service period and to executive officers that vest based on the Company’sachievement of certain performance conditions, primarily, the achievement of a three-year cumulative revenue goal established at the grant date, and are subject to forfeiture in the event the foregoingdate. The grant of awards with performance condition is not met by the end of each respective three-year period. The number of shares that may be earned ranges between 0% (if the specified threshold performance level is not attained) and 200% (if performance meets or exceeds the maximum achievement level) of the target award. If actual performance exceeds the pre-established threshold, the number of shares earned is calculated based on the relative performance between specified levels of achievement. These awards supportconditions supports the Company’s goalsgoal of aligning executive incentives with long-term stockholder value and ensuring that executive officers have a continuing stake in the long-term success of the Company.

At the end of the three-year performance period, if the performance condition is achieved at or above the pre-established threshold, the number of shares earned is further adjusted by a TSR payout percentage, which ranges between 80% and 120%, based on the Company’s TSR performance relative to that of the Russell 1000 Index over the respective three-year period. The Company granted a total of 26,160, 32,160 and 25,680 shares of performance-based restricted common stock during the years ended December 31, 2018, 2017 and 2016, respectively.
