PART I


Item 1.Business

In this report, the words “we,” “our,” “us,” “CoStar” or the “Company” refer to CoStar Group, Inc. and its direct and indirect wholly owned subsidiaries. This report also refers to our websites, but information contained on those sites is not part of this report.


CoStar Group, Inc., a Delaware corporation, founded in 1987, is the number one provider of information, analytics and online marketplaces to the commercial real estate industry in the United States (“U.S.”) and United Kingdom (“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; and provide more information, analytics and marketing services than any of our competitors and believe that we generate more revenues than any of our commercial real estate information and online marketplace competitors. We have created and compiled oura 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 service offerings span all commercial property types, including office, retail, industrial, multifamily, commercial land, mixed-use and hospitality. We manage our business geographically in two operating segments, with our primary areas of measurement and decision-making being North America, which includes the U.S. and Canada, and International, which primarily includes Europe, Asia-Pacific and Latin America. On October 22, 2019, we acquired STR, Inc. and STR Global, Ltd. (together with STR, Inc., "STR"), which provides benchmarking and analytics for the U.K., Spain, Germany and France.hospitality industry. See Note 4 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion of this acquisition.


Strategy


Our strategy is to provide industry professionals and consumers of commercial real estate and apartments with critical knowledge to explore and complete transactions by offering the most comprehensive, timely and standardized information on commercial real estate and apartments and the right tools to be able to effectively utilize that information. Over time, we have expanded, and we continue to expand, our services for commercial real estate information, analytics and online marketplaces in an effort to continue to meet the needs of the industry as it grows and evolves. We have also extended our offering of comprehensive commercial real estate information geographically to include the U.K., Canada, Spain, Germany and France, through acquisitions and internal growth and development. Information about CoStar’s revenues from, and long-lived assets and total assets located in, foreign countries is included in Notes 2 and 11 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Revenues; net income (loss) before interest and other income (expense), income taxes, depreciation and amortization (“EBITDA”); and total assets and liabilities for each of our segments are set forth in Note 11 to our consolidated financial statements. Information about risks associated with our foreign operations is included in “Item 1A. Risk Factors” and “Item 7A. Quantitative and Qualitative Disclosures about Market Risk.”


We deliver our commercial real estate information content to our U.S. customers primarily via an integrated suite of online service offerings that includes information about space available for lease, comparable sales information, information about properties for sale, tenant information, Internet marketing services, analytical capabilities, information for clients’ websites, information about industry professionals and their business relationships, data integration and industry news. We also operate complementary online marketplaces for commercial real estate listings and apartment rentals. We strive to cross-sell our services to our customers and to upsell services that may best suit their needs.

We have five flagship brands - CoStar®, LoopNet®, Apartments.comTM, BizBuySell® and LandsofAmericaTM. 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 subscription-based information services consist primarily of CoStar Suite® services. CoStar Suite is sold as a platform of service offerings consisting of CoStar Property Professional®, CoStar COMPS Professional®and CoStar Tenant® and through our mobile application, CoStar Go®. CoStar Suite is our primary service offering in our North America and International operating segments.

Our LoopNet subscription-based online marketplace enables commercial property owners, landlords, and real estate agents working on their behalf to list properties for sale or for lease and to submit detailed information about property listings. Commercial real estate agents, buyers and tenants use LoopNet extensively to search for available property listings that meet their criteria.



Apartments.comTM is part of our network of apartment marketing sites, which also includes ApartmentFinder.comTM, ForRent.com®, ApartmentHomeLiving.comTM, WestsideRentals.com®, AFTER55.com®, CorporateHousing.comTM, ForRentUniversity.com® and Apartamentos.comTM, our apartment-listing site offered exclusively in Spanish. Our apartment marketing network of subscription-based services offers renters a searchable database of apartment listings and provides professional property management companies and landlords with an advertising destination. Our apartment marketing network draws on and leverages CoStar’s multifamily database, which contains detailed information on apartment properties. We designed the Apartments.com, ApartmentFinder.com and Apartamentos.com websites, which were launched in February 2015, December 2015 and February 2017, respectively, to meet renter preferences and demands, which we believe drives traffic to those sites and attract advertisers who prefer to advertise on heavily trafficked apartment websites. We acquired the ForRent.com, AFTER55.com, CorporateHousing.com and ForRentUniversity.com sites when we completed the acquisition of ForRent, a division of Dominion Enterprises, on February 21, 2018. Our network of apartment marketing sites provide a comprehensive selection of rentals, information on actual availabilities and rents, and in-depth data on neighborhoods, including restaurants, nightlife, history, schools and other facts important to renters. To help renters find the information that meets their needs, the sites also offer innovative search tools such as the PolygonTM Search tool, which allows renters to specifically define the area in which they want to find an apartment. Apartments.com and Apartamentos.com also offer Plan Commute tools, which allow renters to search property listings that meet their transportation needs. The Screening ProsTM is our online apartment leasing platform that includes tenant screening services, rental applications and payments processing and lease renewals.

Our standardized platform includes the most comprehensive proprietary database in the industry; the largest research department in the industry; proprietary data collection, information management and quality control systems; a large in-house product development team; a broad suite of web-based information, analytics and online marketplace services; a large team of analysts and economists; and a large, diverse base of clients.

In addition to our internal efforts to grow the database, we have obtained and assimilated approximately 106a significant number of proprietary databases. Our comprehensive commercial real estate database powers our information services, sources data used in our analytic services and provides content for most of our online marketplace services. Our ability to utilize the same commercial real estate information across our standardized platform creates efficiencies in operations and improves data quality for our customers.

Our services are typically distributed to our clients under subscription-based license agreements that 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 system 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 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. We generally see higher sales of Apartments.com listing services during the peak summer rental season and higher CoStar suite 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 internalorganic growth, we have grown our business through strategic acquisitions. Our more recent acquisitions include theMost recently, on June 1, 2015 acquisition of Network Communications, Inc. (“NCI”), including its Apartment Finder business (collectively referred to as “Apartment Finder”), to further support our expansion into the multifamily vertical. Apartment Finder provides lead generation, advertising, and Internet marketing solutions to property managers and owners through its main service, ApartmentFinder.com. On July 1, 2015,12, 2019, we acquired the assets of Belbex Corporate, S.L.Off Campus Partners, LLC (“Belbex”OCP”), a small commercial real estate information provider operating in Madrid, Spain. On May 3, 2016, we acquired Thomas Daily GmbH (“Thomas Daily”), a commercial real estate news and information provider operating in Freiburg, Germany. On January 31, 2017, we acquired Koa Lei, Inc. (doing business as Westside Rentals and now known as Westside Rentals, LLC), an online marketplace specializing in Southern California real estate rentals, and its affiliated entity Westside Credit Services, LLC, a provider of credit checksstudent housing marketplace content and tenant screening for landlords in the Southern California real estate rental market. On May 10, 2017, we added LandWatch.comtechnology to our network of land-dedicated sites through our acquisition of LandWatch. On July 18, 2017,U.S. universities, and on October 22, 2019, we acquired The Screening Pros, LLC,STR, a global provider of benchmarking and analytics for the hospitality industry. We continue to integrate our recent acquisitions and the services they offer into our CoStar network. See Note 4 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion of these acquisitions.



On February 11, 2020, we agreed to acquire, for $588 million in cash, all the equity interests of RentPath, as reorganized following an online apartment leasing platform that includes tenant screening services, rental applicationsinternal restructuring pursuant to and payments processingunder the joint chapter 11 plan of reorganization of RentPath and lease renewals.

Development, Investments and Expansion

We planare committed to integrate, developsupporting, improving and cross-sell the services offered by ForRent. ForRent.com is expected to remain a distinct, complementary brand to Apartments.com, givingenhancing our information, analytics and online marketplace solutions, including expanding and improving our offerings for property owners, property managers and owners more exposure for their listings.

Development and Expansion

renters. We expect to continue our software development efforts to improve existing services, introduce new services, integrate and cross-sell existing services, and expand and develop supporting technologies for our research, sales and marketing organizations. We are committed to supporting and improving our information, news, analytic and online marketplace solutions.

The launch of the Apartments.com website and the ApartmentFinder.com website in 2015 are examples of our software development efforts to improve existing services, introduce new services, and integrate and cross-sell existing services. We believe the improved sites, enhanced search capabilities, availability of information regarding real-time vacancies and our continued development and introduction of enhancements to our online apartment rental marketplaces have attracted more consumers, making the sites more attractive to property managers, which has also increased our cross-selling opportunities. In 2017, we launched Apartamentos.com, an apartment-listing site offered exclusively in Spanish and built and tailored to meet the needs of Spanish language households in the U.S., which is believed to represent approximately 20 percent of the U.S. renter population. We believe greater functionality makes our services valuable to an even broader audience and helps us increase sales of our services to brokers, banks, owners, institutional investors and other industry participants. We expect technology enhancements to drive continued revenue growth in 2018.



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 result in increased revenues and earnings from sales of other services we offer in lieu of the eliminated or phased out services. In 2017, we began to transition the LoopNet marketplace to a pure pay-to-list/free-to-search marketing site for commercial real estate, and to convert LoopNet information customers to higher value CoStar Suite information services.  We completed integrating the backend systems of the LoopNet and CoStar databases during the second half of 2017; the two services now share a unified database of information, creating operating efficiencies and improving the data available to our customers. We also 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.  In turn, we expect this feature will reduce the time and costs associated with researching and maintaining our comprehensive database of commercial real estate information.
 We continue to assess the potential impact of the transition of the LoopNet marketplace to a pure marketing site for commercial real estate where all listings are paid and users can search the site for free. We are currently focused on converting LoopNet information customers to higher value, more profitable annual subscription information services, which should increase revenues and earnings over time. 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 the LoopNet information services or any other service offering.


Our revenues have increased asOn November 18, 2018, we acquired Cozy Services, Ltd. (“Cozy”), a resultleading provider of revenues from acquired businessesonline rental solutions offering a broad spectrum of services to both landlords and from cross-selling opportunities among the customers of CoStar and the acquired companies.tenants. We expect to continue to increase revenues asintegrate Cozy's online rental and payments technology into the Apartments.com platform, creating an integrated online rental solution. The new platform allows renters to apply for-leases online, for landlords to run tenant credit and background checks and make and process online payments. In 2019, we completed the integration of Realla Ltd. (“Realla”), the operator of a resultcommercial property listings and data management platform that we acquired in October 2018, with our CoStar UK operations. A single point of such cross-selling opportunities. We may incur increased expenses in connection with any marketing and sales campaigns involving cross-selling opportunities and initiatives, and in connection with promotion ofdata entry now allows our new services and brands.


We are expanding the geographic reach of our North America services. In 2014, we began our Canadian research operations in Toronto; in 2015 we expanded into Calgary and Vancouver. In 2016, we began offering services in Ottawa and Edmonton. On July 1, 2015, we expanded our International services into Madrid, Spain through the acquisition of the assets of Belbex, a smallclients to display their commercial real estate information provider operating in Madrid, Spain. Further, on May 3, 2016, we expanded our International services into key markets in Germany,listings through the acquisition of Thomas Daily, aCoStar Suite service offering and to make them visible to prospective tenants and investors through Realla’s marketing portal. Over time, we plan to integrate STR data and services with CoStar Suite to create new products and services for our customers. We plan to drive international expansion, in part, through STR's global operations and to apply STR's benchmarking expertise to other commercial real estate news and information provider operating in Freiburg, Germany. segments served by CoStar.

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, in North America and internationally. We plan to continue to invest in, evaluate and strategically position our sales force as the Company continues to develop and grow. We alsoSpecifically, 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 support the Apartments.com network, to expand into additional Canadian markets and to provide services in Madrid, Spain and key markets in Germany. We established our research operations headquarters in Richmond, Virginia, which is developing into a technology innovation hub, powering the software development necessary to support the content within our information, analytics and marketing services. In connection with the opening of the Richmond research headquarters, we expanded our research team to continue to meet the growing content needs of our clients. In addition, we expectWe plan to continue to investsignificantly increase our investment in our International research operationsApartments.com marketing in Madrid, Spain2020, including search engine marketing and the U.K.TV and digital video advertising. 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 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 within our current platform or expand the reach of 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 generate losses and negative cash flow from operations in the future. We expect to continue our software development efforts to improve existing services, introduce new services, integrate products and services, cross-sell existing services, and expand and develop supporting technologies for our research and sales and marketing organizations. We are committed to continuing to support and improve our information, analytics and online marketplace solutions.


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 have also becomeare 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 real estate and 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


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. By combining our extensive database, researchers, , our experienced team of analysts and economists, technological expertise and broad customer base, we believe that we have created such a platform.


Within theThe apartment rental community, mostadvertising industry serves property managers and owners who are tasked with finding renters to occupy vacant apartments, as 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 primarily supplywe own and operate. Many apartment ILS websites feature only the listingsrental availabilities that larger property owners pay to advertise, and oftenresulting in a poor user experience in which the renter’s search criteria return either limited or no results, irrelevant results or stale results that are inconsistent with the renter's search criteria. These limited results generally do not provide information about therepresent actual rental availabilities.

We believe that consumers expect accurate, actionable and comprehensive apartment rental information. To createOur apartment ILS websites include renter-focused features like the Apartments.com, ApartmentFinder.com,ability to filter search results according to various criteria (e.g., commute time to work); professional images of the properties, including immersive videos and Apartamentos.com3-D interactive models; custom neighborhood profiles; and tenant reviews. Our network of apartment listing websites we drewdraws on our multifamily database and undertookincludes 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 research effort collectingreporting suite that provides customers with rent comparables, making rent trends information publicly available and verifying informationfree digital ad retargeting, and visitingintegrated online rental solutions, including lease applications, and photographing properties.

CoStar Research


We have developed a sophisticated data collection organization utilizing a multi-faceted research process. In 2017, our full time researchers and contractors conducted millions of interviews of brokers, owners, tenants, apartment community owners and property managers. We recently established our research operations headquarters in Richmond, Virginia, which is developing into a technology innovation hub, powering the software development necessary to support the content within our information, analytics and marketing services.



Research Department. Our research professionals undergo an extensive training program so that we can maintain consistent research methods and processes throughout our research department. Our researchers collect and analyze commercial real estate information through millions of phone calls, e-mails and Internet updates, each year, in addition to field inspections, public records review, news monitoring and direct mail.third-party data feeds. We have also set up direct feeds from larger apartment sites and have put in place an automated system that compiles information sourced from the Internet in order to provide the most up-to-date information on rental availabilities.


Our researchers are responsible for maintaining the accuracy and reliability of our database information. As part of their update process, researchers develop cooperative relationships with industry professionals that allow them to gather useful information. Because of the importance commercial real estate professionals place on our data and our prominent position in the industry, many of these professionals routinely take the initiative and proactively report available space and transactions through our on-line tool, Marketing Center, or directly to our researchers.


CoStar has an extensiveCoStar's field research effort that includes physical inspection of properties in order to research new availabilities, find additional property inventory, photograph properties,new construction, collect tenant information, and verify existing information. In 2017, our field researchers drove millions of milesinformation, photograph properties and conducted hundreds of thousands of on-site building inspections.

CoStar utilizes high-tech, field research vehicles across the U.S., Canada, the U.K.primarily within North America and Spain.Europe. A significant majority of these vehicles are customized, energy efficient hybrid cars that are equipped with computers, Global Positioning System tracking software, high resolution digital cameras and handheld laser instruments to help precisely measure buildings and geo-code them and position them on digital maps. Each CoStar vehicle uses wireless technology to track and transmit field data. A typical site inspection consists of photographing the building, measuring the building, geo-coding the building, capturing “For Sale”“for-sale” or “For Lease”“for-lease” sign information, counting parking spaces, assessing property condition and construction, and gathering tenant information. Field researchers also canvass properties, collecting tenant data suite by suite. Wesuite-by-suite. CoStar also utilizeutilizes a low-flying airplane and a fleet of drones to conduct aerial research of commercial real estate. We place researchers on the low-flying aircraft to scout additional commercial developments and take aerial photographs and videos.

Our drone operators in the U.K. and Canada are certified and trained to Civil Aviation Authority standards with a permission for commercial operations pending.

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 3D virtual apartment tours of apartment communities, all of which enhance various CoStar 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 and include what we believe are standard terms, such as a contract term ranging from one to five years, automatic renewal of the contract and fixed periodic license fees or a combination of fixed periodic license fees plus additional fees based upon our usage.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:


callingCalling our information sources on recently updated properties to re-verify information;
performingPerforming periodic research audits and field checks to determine if we correctly canvassed buildings;
providingProviding training and retraining to our research professionals to ensure accurate and standardized data compilation; and

We launched a new weekly column on economic policy that proved so popular we made it available as a separate email newsletter to add more options forsubscribers. We continued to build on our newsletter franchise, giving subscribers the ability to customizeselect the specific topicscoverage they wished to receive in daily emails. In addition, we now showcase news excerpts and types of news they are most interested in. To enhance this aspect of our subscription offering, we redesigned our homepage duringadvertising on the fourth quarter of 2017 to present an engaging and continuously updated interface. This year, we are adding news talent, upgrading technology, and making our service more relevant for subscribers, by delivering specific news based on their individual preferences.publicly available CoStar.com.


We believe the ability to customize and personalize news for the user's specific interests should makemakes 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 provideprovides 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 at http://www.costargroup.com/costar-news/ccrsi.online.

Our sales and marketing efforts have focused and will continue to focus on cross-selling and marketing our services. Similar to our prior acquisitions, we have been cross-selling, and plan to continue to cross-sell, the services offered by Apartments.com and ApartmentFinder.com and the other services we offer, including, but not limited to CoStar Suite. Now that we have completed the ForRent acquisition, we plan to develop and cross-sell the services offered by ForRent. We will also continue to focus on converting LoopNet information users to CoStar as we phase out the LoopNet information service offerings.




Competition


The market for information, analytics and online marketplaces generally is competitive and rapidly changing.extremely dynamic. In the commercial real estate and apartment rentals industries, we believe the principal competitive factors affecting these services and providers are:

We compete directly and indirectly for customers with the following categories of companies:


onlineOnline marketing services, websites or websitesdata exchanges targeted to commercial real estate brokers, buyers and sellers of commercial real estate properties, insurance companies, mortgage brokers and lenders, such as PropertyLine.com, Reed Business Information Limited and its Estates Gazette and Radius Data Exchange products, RealMassive, officespace.com, 42floors, MrOfficeSpace.com,Brevitas, Catylist, Ten-X, RealNex MarketPlace, TenantWise, www.propertyshark.com, Rofo, BuildingSearch.com, CIMLS, CompStak, Rightmove, estatesgazette.com, CommercialCafe, CREXi, Truss, TotalCommercial.com and DebtX;

publicPublic record providers.


As the market for information, analytics and online marketplaces develops, additional competitors (including companies which could have greater access to data, financial, product development, technical, analytic or marketing resources than we do) may enter the 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 Internet 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.

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. Our subscription-based information, analytics and online marketplaces generate the largest portion of our revenues. However, 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 to 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 client 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; or competitive pressures. 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. 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.decline or fail to meet expectations.
 
We may not be able to successfully introduce new or upgraded information, analytics and online marketplace services or combine or shift focus from 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. 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. 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 thereof. In addition, successfully launching and selling a new or upgraded service puts pressureadditional strain on our sales and marketing resources. In 2015, we launched the current Apartments.com and the ApartmentFinder.com websites, both after completing extensive product development. To generate brand awareness and site traffic for Apartments.com, we utilize a multi-channel marketing campaign. The launch of the sites and/or the marketing campaign may not continue to increase brand awareness, site traffic and/or revenues. 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 launch and marketing campaign,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, we invest significant resources in a multi-channel marketing campaign. If the marketing campaign does not continue to increase brand awareness, site traffic and/or revenues, it 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, that overlaps or is redundant with other services we offer, then our customers may choose a competitive service over ours and our revenues may decline and our profitability may be reduced. For example, we continue to assess the impact of transitioning the LoopNet marketplace to a pure marketing site for commercial real estate where all listings are paid and users can search the site for free. We expect to see a short-term reduction in revenues and earnings, as well as reduced search engine optimization. We are working to convert customers to higher value, more profitable annual subscription information services, which should increase revenues and earnings over time, however we cannot predict with certainty whether we will be successful in shifting customers to higher value, more profitable subscriptions and, consequently, in offsetting any reduction in revenues and earnings. Therefore, our revenues and earnings may ultimately decline as a result of the LoopNet conversion to a pure marketing site. In addition, ifIf 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.



If we do not invest in product development and provide services that are attractive to our marketplace 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, then users may become dissatisfied and use competitors’ websites. If we are 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.


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; rising interest rates and slowing transaction volumes 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 improvements in the commercial real estate industry’s leasing activity and absorption rates or a renewed downturn in the commercial real estate market may affect our ability to generate revenues and may lead to more cancellations by our 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.levels, and uncertainty from the expected discontinuance of LIBOR and the transition to any other interest rate benchmark. 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 competitors in attracting advertisers, which could harm 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 than 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 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.




We may be unable to increase awareness of our brands, including CoStar, LoopNet, Apartments.com, BizBuySell and LandsofAmerica, 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, CoStar Showcase, and the Land.com network of rural lands for sale.for-sale. We expect to continue to investincrease our investments in sales and marketing including sales and marketing for our other brandsin 2020 as we seek


to grow the numbers 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 the Apartments.com network of rentalour websites, our business, results of operations and financial condition could be adversely affected.


Our 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 external 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 these investments. Furthermore, our investments may not have their intended effect or produce the expected results. In addition, our external investments, such as capitalized commissions, 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.

We rely on Internet search engines to drive traffic to our websites. If Internet search resultsengines 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!DuckDuckGo and other Internet search websitesengines drive traffic to our websites, including CoStar.com, the Apartments.com network of rental websites, the LoopNet.com network of commercial real estate websites, the BizBuySell.com network of business for-sale websites and LandsofAmerica.com.the Land.com network of land for-sale websites. For example, when a user typesenters in a search query for an apartment building name or address into an Internet search engine, organicthe Internet search engine’s ranking of our Apartments.com webpages will determine how prominently such webpages are displayed inon the search results. However, ourengine results page. Our ability to maintain high organicprominent search result rankings and positioning is not entirely within our control. Our competitors’ search engine optimization, or SEO,Search Engine Optimization (SEO) and Search Engine Marketing (SEM) efforts may result in webpages from their websites receiving a higher search result page rankingrankings than the rankingswebpages from our websites receive, orwebsites. Internet search engines could revise their algorithms and methodologies in a wayways 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 each ofare not prominently displayed, traffic to our websites may decline 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 will occur 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.


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 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.

If 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 businesses depends, in part, on our ability to attract users to our websites. If we fail to maintain or increase traffic to our marketplaces, our ability to acquire additional subscribers or advertisers and deliver leads to and retain existing subscribers and advertisers 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, increases 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 to attract users to our marketplace websites. Our existing and potential competitors include companies that could devote greater technical and other resources than we have available to provide services that users might view as superior to our offerings. Any of our future or existing competitors may introduce different solutions that attract users away from our services or provide solutions similar to our own that have the advantage of better branding or marketing resources. If we are unable to increase traffic to 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.



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, 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, as 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 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 integratemanage 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 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 the preliminary stages of an acquisition,connection with proposed acquisitions, but may ultimately be unable or unwilling to consummate theany particular proposed transaction for various reasons. 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 close the RentPath acquisition when or as expected and we may be unable to fully integrate STR with CoStar when and as expected.

We often incur severance costs and other integration costs post-acquisition, 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.effectiveness, including as a result of unsuccessful integration or because integration with our existing systems puts additional stress on our core infrastructure. 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 acquire complementary businesses.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 ifdenied.  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.

Market volatility
If regulatory approval is denied, we may haveincur significant, additional costs payable to 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.

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 establishing 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 Manager feature on CoStar, or analysis is not current, accurate, comprehensive or reliable, we could experience reduced demand for our services or legal claims by our customers, which could result in lower revenues and higher expenses.





Competition could render our services uncompetitive. 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. Over the past few years, we have increased the rate of investments 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 termacquisition target as a result of investments. Furthermore, our investments may not have their intended effect. In addition, our external investments may lose value and we may incur impairment charges with respectfailure 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.close the transaction.


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, 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-related businesses are uncertain and evolving, and changes in these standards may adversely impact the viability or value of our proprietary rights. 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, could 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 our services may be provided. The laws of certain countries do not protect proprietary rights to the same extent as the laws of the United States and, 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.

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 as copycat websites that may misappropriate our data. Third parties may misappropriate our data through website scraping, robots or other means and aggregate this data on their websites with data from other companies. 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 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 against the misappropriation of our data. Regardless of whether we can successfully enforce our rights against the operators of these websites, any measures that we may take 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. 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. 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 actual or perceived failure to comply with privacy laws and standards could adversely affect our business, financial condition and results of operations. We are dependentdepend on information technology networks and systems to process, transmit and store electronic information and to communicate between our locations around the world and with our clients.clients and vendors. We collect, use and disclose personally identifiable information, including among other things names, addresses, phone numbers and email addresses. We collect, store and use biometric data and sensitive or confidential transaction information and in certain circumstances, credit cardaccount information. In addition, we collect personal information from tenants and landlords, including social security numbers, state or federally issued identification numbers, dates of birth, financial information tax returns,and documents, employment information, background checks and credit scores, which is used into facilitate the apartment rental application and payment process between a renter and for the verification of landlords.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.Act, the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA). Laws and regulations related to privacy and data protection 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 will applywas implemented in all EU member states effective May 25, 2018 and will replacereplaced the current EU Data Protection Directive effective on that date.Directive. The GDPR introducesintroduced new data protection requirements in the EU and imposes substantial fines for breaches of the data protection rules. The GDPR will increaseincreased our responsibility and liability in relation to personal data that we process,process. We continue to assess our compliance with GDPR in light of guidance from data protection authorities, evolving best practices and evolving regulations and we may be requiredneed to put in place additional mechanisms to ensure compliance with the new EU data protection rules. The CCPA, which became effective on January 1, 2020, expands the rights of California residents to access and require deletion of their 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 breaches that may increase data breach litigation. Any failure to comply with the rules arising from the EU Data Protection Directive, the GDPR and related national laws of EU member states, CCPA and other privacy or data protection laws adopted by other jurisdictions, could lead to government enforcement actions and significant penalties against us, and could adversely affect our 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. A violation ofproducts, and may require us to change the way we operate. We may incur substantial fines if we violate any laws or regulations relating to the collection or use of personal information could result in the imposition of fines against us.information.

We have undertaken efforts to conform transfers of personal data from the EEA based on current regulatory obligations, the guidance of data protection authorities and evolving best practices. We continue to review our business practices and the evolving regulations and may find it necessary or desirable to make further changes to our personal data handling or engage in additional efforts to cause our transfer and receipt of EEA residents’ personal data to be legitimized under applicable law. As a result of the adoption of GDPR, we may find it necessary to establish systems to maintain EU-origin data in the European Economic Area, or EEA, which may involve substantial expense and distraction from other aspects of our business. Despite our efforts, we may be unsuccessful in establishing legitimate means of transferring certain data from the EEA, which may vary the current data protection landscape.


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, increase our operating costs, subject us to claims or other remedies and have a material adverse effect on our business, financial condition and results of operations.


Because the interpretation and application of many privacy and data protection laws are uncertain, it is possible that 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 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 yet 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, weWe could be subject to legal claims, government action, harm to our reputation or experienceincur 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 of prospective customers 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 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. 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, among other things:

Interrupt our operations,
Result in our systems or services being unavailable,
Result in improper disclosures of data,
Materially harm our reputation and brands,
Result in significant regulatory scrutiny and legal and financial exposure,
Cause us to incur significant remediation costs,
Lead to loss of customer confidence in, or decreased use of, our products and services,
Divert the attention of management from the operation of our business,
Result in significant contractual penalties or other payments as a result of third-party losses or claims, and
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. The coverage under our insurance policies may not be adequate to reimburse us for losses caused by security breaches.

We are subject to a number of risks related to acceptance of credit cards and debit cards for 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 authorization and processing of credit card transactions, it could cause one or more of the major credit card companies to disallow our continued use of their payment products. 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 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. If we fail to adequately control fraudulent credit card 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’ access to our information, analytics and online marketplaces, which could reduce the demand for our services, lower our revenues and increase our costs.

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 establishing 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 Marketing Center feature on CoStar and LoopNet, or analysis is not current, accurate, comprehensive or reliable, we could experience reduced demand for our services or legal claims by our customers, 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.

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, 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-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, could 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 our services may be provided. The laws of certain countries do not protect proprietary rights to the same extent as the laws of the United States and, 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.

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 as copycat websites that may misappropriate our data. Third parties may misappropriate our data through website scraping, robots or other means and aggregate this data on their websites with data from other companies. 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 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 against the misappropriation of our data. Regardless of whether we can successfully enforce our rights against the operators of these websites, any measures that we may take 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, regardless of their merit, may significantly increase our expenses and adversely affect our stock price. We could be subject to third party claims, lawsuits, or government investigations into whether our business practices comport with applicable law, including antitrust law. Regardless of the merit of such claims or investigations, defending against them could cost us a significant amount of time and money, result in negative publicity, and/or adversely affect our stock price. In addition, if any claims are decided 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.

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. 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. 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, 2017,2019, we had approximately $1.3$1.9 billion of goodwill, including $1approximately $1.7 billion in our North America operating segment and $30approximately $144 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 LoopNet.com network of commercial real estate websites, the Apartments.com network of rental websites, CoStar Showcase, LandandFarm.com and LandsofAmerica.com,the Land.com network of land for-sale websites, could be less attractive to current or potential customers, which could reduce our revenues. The value of our CRE 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 on the number of property listings submitted by brokers, agents, property owners and, in the case of apartment rentals, property managers. This is because an increase in the number of listings increases the utility of the online service and of its associated search, listing and marketing services. If agents marketing large numbers of property listings, such as large brokers in key real estate markets, 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 our other marketplaces, including BizBuySell and BizQuest,the BizBuySell.com network of business for-sale websites, are also dependent on attracting and retaining listings.


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 usedaccustomed 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 salefor-sale marketplaces rather than traditional methods of listing and marketing businesses for sale,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 imposesimpose 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 international acquisitions of CoStar U.K. Limited (formerly FOCUS Information Limited), Property and Portfolio Research Ltd., Grecam S.A.S., the assets of Belbex Corporate, S.L., Thomas Daily, as well as our expansion into Canada,efforts, a portion of our business is denominated in the British Pound, Euro and Canadian dollar.foreign currencies. As a result, fluctuations in foreign currencies may have an impact on our business, results of operations and financial position. 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.KU.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 U.K.British government and the E.U. and other E.U. member states to negotiate the terms of the withdrawal.governments. Uncertainty over the terms ofregarding the U.K.’s withdrawal from the E.U. 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 could result in significant volatility in global equity markets, currency exchange rates and other asset prices, including those related to real property. The impact to us from Brexit will depend, in part, on the outcome of tariff, trade, regulatory and other negotiations.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 could potentially disrupt the markets we serve 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 couldis likely to 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 changesFor example, 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. Refer to Management's Discussion and Analysis of Financial Condition and Results of Operations of this Form 10-K for additional discussion of the impact of tax reform on the business. We cannot predict the impact, if any of potential future additional changes to our business. 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 could be adversely affected.

In December 2017, the United States enacted The Tax Cuts and Jobs Act (the "Tax Act"), and various provisions of the new law may adversely affect us. Certain aspects of Tax Reform are unclear and may not be clarified for some time. As required by Securities and Exchange Commission Staff Accounting Bulletin 118, Income Tax Accounting ImplicationsDuring 2018, the Department of the Tax CutsTreasury issued certain guidance in the form of notices and Jobs Act, we have provided a provisional estimate onproposed regulations with respect to several provisions of the effect ofnew legislation. We expect that additional regulations or other guidance may be issued with respect to the Tax Act in subsequent years. We continue to examine the impact this tax reform legislation may have on our consolidated financial statements. However, we may be required to change our provisional estimates as a result of new accounting guidance, regulatory guidance, judicial interpretations or our continued analysis of the application of the law, which could materially affect our tax obligations and effective tax rate.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 taxes could increase, and our business, financial condition or results of operations may be adversely impacted.


Our indebtedness could adversely affect us, including by decreasing our business flexibility and increasing our costs. On October 19, 2017, we entered into an amended and restated credit agreement (the ‘‘2017 Credit Agreement’’), which amended and restated in its entirety the existing credit agreement dated April 1, 2014 (the "2014 Credit Agreement"), by and among CoStar, as borrower, CoStar Realty Information, Inc., as co-borrower, the lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as administrative agent. 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 2017 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 subsidiaries to, among other things, (i) incur additional indebtedness, (ii) create, incur, assume or permit to exist any liens, (iii) enter into mergers, consolidations or similar transactions, (iv) make investments and acquisitions, (v) make certain dispositions of assets, (vi) make dividends, distributions and prepayments of certain indebtedness and (vii) enter into certain transactions with affiliates.


The operating restrictions and financial covenants in the 2017 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 terms of the 2017 Credit Agreement. If an event of default occurs, the interest rate on any overdue amounts will increase and the lenders under the 2017 Credit Agreement may declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable and may exercise remedies in respect of the collateral. We may not be able to repay all amounts due under the 2017 Credit Agreement in the event these amounts are declared due upon an event of default.


Negative conditions in the global credit markets may affect the liquidity of a portion of our long-term investments.  Currently, our long-term investments include mostly AAA-rated auction rate securities (“ARS”), which are primarily student loan securities supported by guarantees from 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 salefor-sale has exceeded the amount of purchase orders for such securities. As of December 31, 2017,2019, we held $11 million par value of ARS, all of which failed to settle at auctions. When an auction fails for ARS in which we have invested, we 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 a 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 would reduce our profitability and adversely affect our financial position.



Our ARS 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. We have used a discounted cash flow model to determine the estimated fair value of our investment in ARS as of December 31, 2017. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of cash flows, liquidity risk premiums, expected holding periods and default risk of the ARS. We update 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. Based on this assessment of fair value, as of December 31, 2017, we determined there was a decline in the fair value of our ARS investments of approximately $730,000. The decline was deemed to be a temporary impairment and was recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. If the issuers of these ARS are unable to successfully close future auctions and/or their credit ratings deteriorate, we 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, which would reduce our profitability and adversely affect our financial position.

We have not made any material changes in the accounting methodology used to determine the fair value of the ARS. We do not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used to calculate the fair value of the ARS as of December 31, 2017. However, if changes in these assumptions occur, and, should those changes be significant, we 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.

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’ access to our information, analytics and online marketplaces, which could reduce the demand for our services, lower our revenues and increase our costs.

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.

Our operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to seasonality and market cyclicality, each of which could cause our stock price to be negatively affected. The commercial real estate market may be influenced


by general economic conditions, economic cycles, annual seasonality factors 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. We generally see higher sales of Apartments.com listing services during the peak summer rental season and higher CoStar Suite sales towards the end of the year, however sales fluctuate from year-to-year. In addition, our results may be impacted by seasonality.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 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 CoStarus to maintain certain business practices that the FTC believes are pro-competitive. For example, the consent order requires CoStarus to license itsour products to customers who have bought its competitors' products on a non-discriminatory basis. In addition, CoStar iswe 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 CoStarus from realizing anticipated benefits of an acquisition. In the event that CoStar failswe fail or isare unable to comply with the terms of the consent order, CoStarwe could be subject to an enforcement proceeding that could result in substantial fines and/or injunctive relief.


We have incurred and will continue to incur acquisition-related costs.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.

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.

Subscription-Based Services

Our subscription-based services consist primarily of information, analytics and online marketplace services offered overFor 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, 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 system 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 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 in advance on a monthly basis, but in some cases may pay us in advance on a quarterly or annual basis.

As ofyears ended December 31, 20172019, 2018 and 2016,2017 our annualized net new bookings of subscription-based services on all contracts were approximately $43$210 million, $169 million and $29$148 million, respectively, calculated based on the annualized amount of change in our sales resulting from all new subscription-based contracts or upsales on all existing subscription-based contracts, less write downs and cancellations, for the period reported. Our net bookings isWe recognize subscription revenues on a quantitative measurement that is typically closely correlated with our subscription revenue results.straight-line basis over the life of the contract. Net bookings is considered a key indicator of future subscription revenue growth and is also used as a metric of salesforce productivity by management and investors. We recognize subscription revenues on a straight-line basis over the life of the contract.




For each of the twelve monthsyears ended December 31, 20172019, 2018 and 2016,2017, our contract renewal rate for existing CoStar subscription-based services on annual contracts was approximately 91%90%, 90% and 90%,91% respectively, and, therefore, our cancellation rate for those services was approximately 9%10%, 10%, and 10%9%, respectively, for the same time periods.respectively. Our contract renewal rate is a quantitative measurement that is typically closely correlated with our revenue results. As a result, management also believes that the rate may be a reliable indicator of short-term and long-term performance. Our trailing twelve-month contract renewal rate may decline if, among other reasons, negative economic conditions lead to greater business failures and/or consolidations among our clients, reductions in customer spending, or decreases in our customer base.


Development, Investments and Expansion


We are committed to supporting, improving and enhancing our information, analytics and online marketplace solutions, including expanding and improving our information, news, analyticofferings for property owners, property managers and online marketplace solutions.renters. 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. To generate brand awareness and site traffic for our listing sites, we utilize a variety of marketing campaigns, 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 in 2018. As we continue to assess the success and effectiveness of our marketing campaign, we will continue to work to determine the optimal level of marketing investment for our services for future periods.


Our key priorities for 20182020 include:

Continue to develop, improve and recent developments include:

We are migrating all ofmarket our commercial real estate information capabilities to our flagship CoStar Suite product and winding down the legacy LoopNet Information products.  This process began in the fall of 2017 with the integration of the CoStar and Loopnet databases.  In addition, we are transitioning the LoopNet marketplace to a pure pay-to-list marketing site for commercial real estate. We completed integrating the backend systems of the LoopNet and CoStar databases during the second half of 2017; the two services now share a unified database of information, creating operating efficiencies and improving the data available to our customers.  We also introduced new enhancementsrecently launched Apartments.com service offerings that focus on the CoStar homepage, including a Listing Manager feature that we believe will increase the quantitydigital rental experience and quality of the listing information available by enabling brokers and other industry participants to load information directly into the integrated system.  This in turn is expected to reduce the time and costs associated with researching and maintaining our comprehensive database of commercial real estate information.

On February 21, 2018, 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. We plan to integrate, develop and cross-sell the services offered by ForRent. ForRent.com is expected to remain a distinct, complementary brand to Apartments.com, giving property managers and owners more exposure for their listings.

We plan to continue developing new, and improve existing, product and service offerings to the apartments industry. In particular, we expect to implement the ability forenable renters to apply for leases online,for-leases, and for landlords to run tenant credit and background checks and eventually, for landlordsmake rent payments, all online through a single platform. We plan to aggressively market our multifamily listing services in an effort to provide more value to advertisers and, tenantsin turn, to generate leasesattract advertisers. As such, we plan to increase our investment in Apartments.com marketing in 2020 by approximately $100 million, which may reduce our margins and process payments online.

We continue toprofitability while we invest in our research operations to support continued growth of our informationfuture growth. The increased investment is focused on search engine marketing and analytics offerings.enhanced brand awareness. We established our research operations headquarters in Richmond, Virginia, in December 2016, which is developing into a technology innovation hub, powering the software development necessary to support the content within our information, analytics and marketing services. In connection with the opening of the Richmond research headquarters, we have expanded our research team to continue to meet the growing content needs of our clients. In addition, we expectalso plan to continue to invest in our International research operations in Madrid, Spainmultifamily business by increasing the size of our sales force with a focus on increasing sales to midsize and the U.K.smaller apartment communities.

Obtaining necessary bankruptcy court and regulatory approvals to close the pending acquisition of RentPath and integrating RentPath with the Apartments.com network post-closing. On February 11, 2020, a wholly owned subsidiary of the Company entered into an agreement to acquire for $588 million in cash all of the equity interests of RentPath Holdings, Inc., as reorganized following an internal restructuring pursuant to and under the joint chapter 11 plan of reorganization of RentPath and certain of its subsidiaries. Closing of the acquisition is subject to customary closing conditions, including the expiration or termination of any applicable waiting period under applicable antitrust laws and approval by the bankruptcy court. See Note 19 to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K for further discussion.


In support
Continue to invest in the LoopNet marketplace by enhancing the content on the site (including high-quality imagery), seeking targeted advertisements, providing premium listing services (such as LoopNet Signature Ads) that increase a property listing’s exposure, and adding more content for premium listings to better meet the needs of our continued expansion and development, in October 2017, we completed a public equity offering of 3,317,308 shares of common stock for $260.00 per share. Net proceeds from the public equity offering were approximately $834 million, after deducting approximately $29 million of underwriting discounts and fees. We expect to use the net proceeds from the public equity offering to fund all or a portionbroader cross section of the costscommercial real estate industry. Additionally, we initiated training and incentive programs for our sales team to increase sales of any strategicLoopNet Signature Ads, with a focus on property owners.

Integrating recently completed acquisitions, we determineincluding STR, with CoStar’s business operations. We plan to pursueconsolidate STR data and services with CoStar Suite to create an integrated platform. We plan to drive international expansion, in part, through STR's global operations and to apply STR's benchmarking expertise to other commercial real estate segments served by CoStar.

Continue to invest in CoStar Suite, including capabilities that allow us to broaden the future,reach of CoStar Suite in Europe by offering multiple languages and currencies on the platform. We plan to finance the growth of our business and for working capital and other general corporate purposes. General corporate purposes may include additions to working capital, capital expenditures, repayment of debt,enhance CoStar Suite by making additional investments in analytical capabilities focused on owners and lenders of commercial real estate. In addition, we plan to invest in integrating the Company’s subsidiaries, possible acquisitionstechnology and infrastructure from other existing service offerings into the repurchase, redemption or retirement of securities,CoStar Suite platform, including the Company’s common stock.CoStar Real Estate Manager, in order to leverage data and technology across our platforms and provide customers with additional functionality.

On October 19, 2017, the Company entered into an amended and restated credit agreement (the ‘‘2017 Credit Agreement’’), which amended and restated in its entirety the existing 2014 Credit Agreement. 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 Company also paid off the remaining balance of $310 million and interest on its existing $400 million term loan under the 2014 Credit Agreement on October 19, 2017 from existing cash balances. The 2017 revolving credit facility may be used for working capital and other general corporate purposes of the Company and its subsidiaries. The Company had no outstanding long-term debt at December 31, 2017 as it had not drawn any amounts under its 2017 Credit Agreement. The restructured credit facility, along with the proceeds from the October equity offering and cash generated by the Company’s business are expected to support the Company’s continued growth and give the Company flexibility to act on strategic acquisition opportunities that may arise.


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.




Property Developments

As we have done in the past, we expect to continue to identify new facilities and consolidate existing facilities to better accommodate the changing demandsFor further discussion of our Company, strategy and products, see our business operations and employees. As a result, we may incur additional lease restructuring charges for the abandonment of certain lease space and the impairment of leasehold improvements.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"(“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 other 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 other 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, acquisitionacquisition- and integration relatedintegration-related costs for pending and completed acquisitions, restructuring costs and settlements and impairments incurred outside our ordinary course of business. Non-GAAP net income and non-GAAPis determined by adjusting our net income per diluted share are similarly adjusted for stock-based compensation expense, acquisitionacquisition- and integration relatedintegration-related costs for pending and completed acquisitions, restructuring costs, settlement and impairment costs and loss on debt extinguishment incurred outside our ordinary course of business and loss on debt extinguishment, as well as amortization of acquired intangible assets and other related costs.costs, and then subtracting an assumed provision for income taxes. 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, non-GAAP net income and non-GAAP net income per diluted share as operating performance measures and as such 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-GAAPnon-


GAAP net income per diluted share, we exclude from net income (loss) 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 (loss) 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 the accompanying reconciliation,reconciliations, provide additional information to investors that is useful to understand the factors and trends affecting our business. 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 included acquisitions, our net income has included significant charges for amortization of acquired intangible assets, depreciation and other amortization, acquisitionacquisition- and integration relatedintegration-related costs for pending and completed acquisitions, 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, acquisitionacquisition- and integration relatedintegration-related costs for pending and completed acquisitions, 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. 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, income taxes, stock-based compensation expenses, acquisitionacquisition- and integration relatedintegration-related costs for pending and completed acquisitions, restructuring 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 :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 database 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 and other income and expense we generate may be useful for investors to consider and may result in current cash inflows. However, we do not consider the amount of interest and other income to be a representative component of the day-to-day operating performance of our business.

The amount of interest and other expense we incur may be useful for investors to consider and may result in current cash inflows and outflows. However, we do not consider the amount of interest and other 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 and may result in current cash outflows. 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:


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 acquisitionacquisition- and integrationintegration- related costs for pending and completed acquisitions 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 acquisitionacquisition- and integrationintegration- related costs for pending and completed acquisitions 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 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 loss on our debt extinguishment may be useful for investors to consider because they generally represent gains or 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.


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, acquisitionacquisition- and integrationintegration- related costs for pending and completed acquisitions, restructuring and related costs and settlement and impairment costs and loss on debt extinguishment 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. In addition to these exclusions from net income, (loss). Wewe subtract an assumed provision for income taxes to calculate non-GAAP net income. In 2017, 2016,2019 and 2015,2018, we assumed a 38%25% tax rate which approximatesapproximated our historical long-term statutory corporate tax rate, excluding the impact of discrete items.


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 understand the factors and trends affecting our business.

Revenues. Revenues increased to $965 million$1.4 billion in 2017,2019, from $838 million$1.2 billion in 2016.2018. The $127$208 million increase was primarily attributable to increased revenues of approximately $55an $85 million, or 13% from continued organic growth21%, increase in CoStar Suite as well as a movementmultifamily revenue. The multifamily increase was due to upgrades of our Loopnet customers onto our CoStar platformexisting customer packages to higher value advertising packages, higher volume as a result of recent investments in marketing, and to a lesser extent, growth from the Loopnet integration. Information Services decreased $5Macquisitions of Cozy and OCP. CoStar Suite revenues increased $73 million, or 6%13%, primarily due to continued wind down of Loopnet Information products including Premium Searcher partially offset byfurther increases in pricing and, to a lesser extent, further market penetration and cross-selling of our services.

Commercial Property and Land revenue increased $22 million or 18% over 2016 primarily due to organic growth as well as an increase due to the Landwatch acquisition. Overall, revenue growth rates are expected to be in line or slightly higher than 2017.acquisition of STR.


Gross Profit. Gross profit increased to $745$1.1 billion in 2019, from $922 million in 2017, from $664 million in 2016.2018. The gross marginprofit percentage decreasedwas 79% for 2019 compared to 77% in 2017, from 79% in 2016. Revenue growth led to anfor 2018 as revenues increased at a higher rate than cost of revenues. The increase in costscost of revenues of $38$19 million, or 7%, was primarily due to additional merchant fees and data and content costs of $9 million, primarily attributable to the acquisition of Cozy, additional personnel costs of $8 million and additional costs for additionalresearch equipment of $3 million. The increase from the prior year was partially offset by nonrecurring research personnel restructuring costs $5 million in occupancy related costs from our new research office in Richmond offset by a decreaseincurred in the amortizationprior year of intangible assets of$4$3 million. Gross margins are impacted by the amortization of certain intangible assets acquired through acquisitions.


Selling and Marketing Expenses. Selling and marketing expenses increased to $318$409 million in 2017,2019, from $296$360 million in 2016,2018.

Net cash used in investing activities for the year ended December 31, 20172019 was $72$484 million compared to $23$448 million for the year ended December 31, 20162018. The $36 million increase in cash used in investing activities was primarily due to approximately $418 million of net cash paid to acquire ForRent, Cozy and $216Realla during 2018, compared to $438 million net cash paid during 2019 for the STR and OCP acquisitions. During 2019, we made capital expenditures of approximately $46 million compared to approximately $30 million during 2018. The increase in capital expenditures during the year ended December 31, 2015. The $49 million increase in investing activities in 2017 compared to 20162019 was primarily due topartially driven by the increase in cashpurchase of a corporate aircraft, which is principally used for acquisitions from 2016 to 2017. 2017 included cash payments for the acquisitions of Westside Rentals for $14 million, a $31 million payment for LandWatch and a $3 million payment for the acquisition of The Screening Pros. 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. We expect capital expenditures to increase in 2018 related to the build out of leased office space, including the Richmond research headquarters, as well as investments in technology.business travel by our executives.

The $192 million decrease in investing activities in 2016 compared to 2015 was primarily due to the decrease in cash used for acquisitions from 2015 to 2016. The $182 million of net cash used for acquisitions in 2015 included $179 million for the acquisition of Apartment Finder and certain assets related to the business operations of Apartment Finder's independent distributors as well as $3 million for the acquisition of the assets of Belbex Corporate, S.L. In 2016, we spent $10 million for the acquisitions of Thomas Daily and certain assets related to the business operations of Apartment Finder's independent distributors. During 2016, we incurred capital expenditures of approximately $19 million primarily related to computer equipment and leasehold improvements for build out of sales office space.


Net cash provided byused in financing activities for the year ended December 31, 20172019 was $480$4 million compared to net cash used inprovided by financing activities of $31$3 million for the year ended December 31, 2016 and $29 million in December 31, 2015.2018. This $511$7 million increase from 2016in cash used in financing activities in 2019 compared to 20172018 was primarily due to $834higher repurchases of restricted stock to satisfy employee tax withholding obligations upon vesting of restricted stock awards of $3 million, as well as a decrease in net proceeds from our equity offering offset by an increase in debt repayments in 2017the exercise of $325employee stock options of $2 million.


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. On January 31, 2017, we acquired Westside Rentals; on May 10, 2017, we acquired LandWatch; and on July 18, 2017, we acquired The Screening Pros. On February 21, 2018, we completed11, 2020, our wholly owned subsidiary entered into a purchase agreement to acquire all of the acquisitionequity interests of ForRent,reorganized RentPath, following an internal restructuring pursuant to a divisionchapter 11 plan of Dominion Enterprises,reorganization, for approximately $350$588 million in cash. The purchase agreement requires us to pay a $59 million fee in the event the purchase agreement is terminated prior to closing under specified circumstances. The acquisition will be funded using cash and approximately $35 millionon hand. See Note 19 to the accompanying Notes to the Consolidated Financial Statements included in CoStar Group stock, subject to customary working capital and other post-closing adjustments. Our future acquisitions may vary in size and could be material to our current operations. We may use cash, stock, debt or other meansPart IV of funding to make these acquisitions.  

On October 19, 2017, the Company entered into the ‘‘2017 Credit Agreement’’, which amended and restated in its entirety the existing 2014 Credit Agreement.

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 goodwill
ValuationRevenue recognition
Income taxes
Business combinations

With respect to our accounting policy for long-lived assets, intangible assets and goodwill, we further supplement in Note 2 of Long-Lived and Intangible Assets and Goodwillthe 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 excess of costs over the fair value of assets of acquired businesses. Goodwill is not amortized, but instead tested for impairment at least annually by each reporting unit. The CompanyWe 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. 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 the fair value of our 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, 2017,2019, we assessed the date of our most recent impairment analysis,relevant qualitative factors and concluded that it was not more likely than not that the estimated fair value of each of our reporting units substantially exceeded thewas less than their respective carrying value of our reporting units.amounts. There have been no events or changes in circumstances since the dateas a result of our qualitative impairment analysis on October 1, 2017,2019, that would indicate that the carrying value of each reporting unit may not be recoverable.









Revenue Recognition

We recognize revenues when (1) there is persuasive evidenceFor an in-depth discussion of an arrangement, (2) the fee is fixed or determinable, (3) services have been renderedeach of our significant accounting policies, including our critical accounting policies and payment has been contractually earnedfurther information regarding estimates and (4) collectability is reasonably assured. Revenues from subscription-based services are recognized on a straight-line basis over the term of the agreement. We evaluate our allowance for doubtful accounts and estimate collectability of accounts receivable based on our analysis of historical collection experience, changesassumptions involved in customer payment profiles and the aging of receivable balances, as well as current economic conditions, all of which may affect a customer’s ability to pay. A credit reserve has also been established based on historical experience of credits issued to customers to ensure that revenue is recognized appropriately in the current period. Deferred revenue results from advance cash receipts from customers or amounts billed in advance to customers from the sale of subscription services and is recognized over the term of the service agreement.

We derive revenues by providing access to our proprietary database of commercial real estate information. We generally charge a fixed monthly amount for our subscription-based services. 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. 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, as applicable. A majority of the subscription-based service agreements have a term of one year and renew automatically.

We analyze contracts with multiple elements under the accounting guidance for multiple-element arrangements. Our multiple-element arrangements include information, analytics and/or online marketplace services that are generally providedtheir application, see Note 2 to the customer over the same term. When identifying multiple-element arrangements, we consider multiple purchases made by the same customer within a short time frame and assess whether the purchases were negotiated together as one overall arrangement. If a multiple-element arrangement is identified, then the arrangement consideration is allocated among the separate units of accounting based on their relative selling prices, which is estimated considering factors such as historical pricing, pricing strategy, market conditions and other factors. We account for each deliverable in the transaction separately. If the deliverables cannot be separated into multiple units of accounting, then the arrangement consideration is combined and recognition of revenues is determined for the combined unit of accounting. Multiple-element transactions require judgment to determine the selling price or fair value of the different elements. The judgments impact the amount of revenues recognized over the term of the contract, as well as the period in which they are recognized.

Accounting for Income Taxes

As part of the process of preparing ouraccompanying consolidated financial statements we are required to estimate our income taxesincluded in each of the jurisdictions in which we operate. This process requires us to estimate our current tax exposure and assess the temporary differences resulting from differing treatment of items, such as deductibility of certain intangible assets, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheets. We must then also assess the likelihood that our deferred tax assets will be recovered from future taxable income, and, to the extent we believe that it is more-likely-than not that some portion or all of our deferred tax assets will not be realized, we must establish a valuation allowance. To the extent we establish a valuation allowance or change the allowance in a period, we must reflect the corresponding increase or decrease within the tax provision in the consolidated statements of operations.this Annual Report on Form 10-K.

We generally recognize the effect of the tax law changes in the period of enactment. Changes in existing tax laws and rates, their related interpretations, and the uncertainty generated by the current economic environment may affect the amounts of our deferred tax liabilities or the valuations of our deferred tax assets over time. Our accounting for deferred tax consequences represents management’s best estimate of future events that can be appropriately reflected in the accounting estimates. In accordance with SEC Staff Accounting Bulletin 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, we report provisional amounts if we are able to determine a reasonable estimate but do not have the necessary information available, prepared, and analyzed in reasonable detail to complete the accounting for Tax Reform. We may revise our estimates as we finalize our accounting during a measurement period of up to one year from the enactment of Tax Reform.



Stock-Based Compensation

We account for equity instruments issued in exchange for employee services using a fair-value based method and we recognize the fair value of such equity instruments as an expense in the consolidated statements of operations. We estimate the fair value of each option granted on the date of grant using the Black-Scholes option-pricing model, which requires us to estimate the dividend yield, expected volatility, risk-free interest rate and expected life of the stock option. For equity instruments that vest based on a market condition, we estimate the fair value of each equity instrument granted on the date of grant using a Monte-Carlo simulation model, which also requires us to estimate the dividend yield, expected volatility, risk-free interest rate and expected life of the equity instruments. These assumptions and the estimation of expected forfeitures are based on multiple factors, including historical employee behavior patterns of exercising options and post-employment termination behavior, expected future employee option exercise patterns, and the historical volatility of our stock price. For equity instruments that vest based on performance, we assess the probability of the achievement of the performance conditions at the end of each reporting period, or more frequently based upon the occurrence of events that may change the probability of whether the performance conditions would be met. If our 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.

We do not expect any material changes in the near term to the underlying assumptions used to calculate stock-based compensation expense for the year ended December 31, 2017. However, if changes in these assumptions occur, and, should those changes be significant, they could have a material impact on our stock-based compensation expense.

Business Combinations

We allocate the purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customer bases, acquired database technology, and acquired trade names from a market participant's perspective, useful lives and discount rates. During the measurement period, we may record adjustments to the assets acquired and liabilities assumed. 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.

Fair Value of Auction Rate Securities

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 assets and liabilities by the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; 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. Our Level 3 assets consist of auction rate securities ("ARS"), whose underlying assets are primarily student loan securities supported by guarantees from the Federal Family Education Loan Program (“FFELP”) of the U.S. Department of Education.

Our ARS 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. We have used a discounted cash flow model to determine the estimated fair value of our investment in ARS as of December 31, 2017. 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 of the ARS. We update 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 our estimate of the yield expected by a market participant from the ARS investments. The weighted average discount rate used in the discounted cash flow model as of December 31, 2017 and 2016 was approximately 6% and 5%, respectively. 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, 2017, we determined there was a net decline in the fair value of our ARS investments of approximately $730,000. The decline was deemed to be a temporary impairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. If the issuers of these ARS are unable to successfully close future auctions and/or their credit ratings deteriorate, we 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, which would reduce our profitability and adversely affect our financial position.

We have not made any material changes in the accounting methodology used to determine the fair value of the ARS. We do not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used to calculate the fair value of the ARS as of December 31, 2017. However, if changes in these assumptions occur, and, should those changes be significant, we may be exposed to additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments.


Recent Accounting Pronouncements


In March 2016, the FASB issued authoritative guidance to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification of share-based payment transactions on the statement of cash flows. Effective the first quarter of 2017, the Company adopted the standard, which impacted our 2017 net income because excess tax benefits, which were previously reflected in additional paid in capital, are now reflected in income tax expense. The significance of the impact will depend on the intrinsic value at the time of vesting or exercise of equity instruments.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350: Simplifying the Test for Goodwill Impairment, which is designed to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The guidance indicates that an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This guidance is effective on a prospective basis for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. Early application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted this guidance during the first quarter of 2017 and the early adoption did not have a material impact on the Company's consolidated financial statements and related disclosures.




See Note 2 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for additional information on recent accounting pronouncements, including the expected dates of adoption.


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 STR 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 year ended December 31, 2017,2019 and December 31, 2018, revenues denominated in foreign currencies waswere approximately 4% and 3%, respectively, of total revenue. For the year ended December 31, 2017,2019 and December 31, 2018, our revenues would have decreased by approximately $6 million and $3 million if the U.S. dollar exchange rate used strengthened by 10%. For the year ended December 31, 2017,2019 and December 31, 2018, our revenues would have increased by approximately $6 million and $3 million 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, 2017,2019, accumulated other comprehensive loss included a loss from foreign currency translation adjustments of approximately $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, 2017.2019. As of December 31, 2017,2019, we had $1$1.1 billion of cash and cash equivalents and short-term investments.equivalents. 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, 2017,2019, $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. Based on an assessment of fair value of these investments in ARS as of December 31, 2017, we determined that there was a decline in the fair value of our ARS investments of approximately $730,000, which was deemed to be a temporary impairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. 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 our cash and cash equivalents, and our expected operating cash flows, we do not anticipate having to sell these securities below par value in order to operate our business in the foreseeable future. See Notes 35 and 46 to the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for further discussion.


We had approximately $1.5$2.3 billion inof goodwill and intangible assets as of December 31, 2017.2019. As of December 31, 2017,2019, 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.

Management’s Report on Internal Control over Financial Reporting


Management of CoStar 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, 20172019 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, 20172019.


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 January 31, 2017,June 12, 2019, we completed the acquisition of Westside Rentals. On May 10, 2017,OCP and on October 22, 2019, we completed the acquisition of LandWatch. On July 18, 2017, we completed the acquisition of The Screening Pros.STR. As permitted by the Securities and Exchange Commission, we have elected to exclude the accounts receivableinternal controls of these acquisitions that have not been integrated into our existing processes and revenue of Westside Rentals, LandWatch, and The Screening Proscontrols from our assessment of the effectiveness of internal control over financial reporting as of December 31, 2017.2019. The excluded aggregate financial position of Westside Rentals, LandWatch,OCP and The Screening ProsSTR represented less than 1% of our total assets as of December 31, 2017,2019, and less than 1% and 2% of our revenues and net income, respectively, for the year then ended. We will include the internal controls of Westside Rentals, LandWatch,OCP and The Screening Pros accounts receivable and revenueSTR in our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2018.2020.




During the fourth quarter of 2017, we commenced the implementation of a new financial system that is designed to improve the efficiency and effectiveness of the Company’s operational and financial accounting processes. This implementation is expected to continue through 2019. 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.

Other than the implementation of a new financial system noted previously, there have been no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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, 20172019 and 2016, and2018, the related consolidated statements of operations, comprehensive income, (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2017,2019, and the related notes and the financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Company at December 31, 20172019 and 2016,2018, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2019, 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, 2017,2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 22, 201826, 2020 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.
Adoption of ASU No. 2016-02
As discussed in Note 2 to the consolidated financial statements, the Company changed its method for accounting for leases in 2019 due to the adoption of Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842), 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
Description of the Matter
As described in Note 4 to the consolidated financial statements, during the year ended December 31, 2019, the Company completed the acquisition of STR, Inc. and STR Global, Ltd. (together with STR, Inc. referred to as “STR”) for $435 million in cash. The Company’s accounting for the acquisition included determining the fair value of the acquired intangible assets including customer relationships of $139 million.
Auditing the accounting for the acquired intangible assets of STR 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 respective fair values to the underlying assumptions, including discount rates, projected revenue growth rates, customer attrition rates and projected profit margins. These significant assumptions are forward-looking and could be affected by future 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.

Report of Independent Registered Public Accounting Firm


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


Opinion on Internal Control over Financial Reporting
We have audited CoStar Group, Inc.’s internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CoStar Group, Inc.(the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2019, based on the COSO criteria.
As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Westside Rentals, LandWatchOff Campus Partners, LLC, STR, Inc. and The Screening Pros related to accounts receivable and revenues,STR Global, Ltd., which are included in the 20172019 consolidated financial statements of CoStar Group, Inc., and collectively constituted less than 1% of total assets as of December 31, 20172019 and less than 1% and 2% of total revenues and net income, respectively, for the year then ended.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.




Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

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, 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,goodwill; income taxes, fair value of equity instruments,the 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


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, 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, analytics and online marketplace services offered over the Internet to commercial real estate industry and related professionals. 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.

In limited circumstances, the Company's contracts with customers 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, which involves the determination of the standalone selling price for each distinct performance obligation.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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 of the Company's revenue recognition.

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 anticipatesdetermines it is more likely than not that some portion or all of an asset may not be realized through future taxable earnings or implementation of tax planning strategies.realized. Interest and penalties related to income tax matters are recognized in income tax expense.

The Company has elected to record the global intangible low taxed income inclusion ("GILTI") under the current-period cost method.

See Note 912 for additional information regarding income taxes.


Net Income (Loss) Per Share


Net income (loss) per share is computed by dividing net income (loss) by the weighted averageweighted-average number of common shares outstanding during the period on a basic and diluted basis. The weighted-average number of common shares outstanding during the period used for purposes of calculating basic earnings per share excludes stock options and stock-based awards which include restricted stock awards that vest over a specific service period, restricted stock awards that vest based on achievement of a performance condition, restricted stock awards with a performance and a market condition, restricted stock units and Matching restricted stock units ("Matching RSUs) awarded under the Company's Management Stock Purchase Plan (the “MSPP”). The Company’s potentially dilutive securities include outstanding stock options and unvested restricted stock.stock-based awards. Shares underlying unvested restricted stock-based awards that vest based on performance and market conditions that have not been achieved as of the end of the period are not included in the computation of basic or diluted earnings per share. Diluted net income (loss) per share considers the impact of potentially dilutive securities except in periods in which there is a net loss, aswhen the inclusion of the potentially dilutive common sharessecurities would have an anti-dilutive effect. See Note 16 for additional information on the Company's calculation of net income per share.



Stock-Based Compensation

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.

In March 2017, March 2016 and March 2015, the Compensation Committee of the Board of Directors of the Company approved grants of restricted common stock to the executive officers that vest based on the Company’s achievement of a three-year cumulative revenue goal established at the grant date, and are subject to forfeiture in the event the foregoing performance condition is not met by the end of each respective three-year period. These grants of restricted common stock are also subject to continuing employment requirements and a market condition based on total shareholder return (“TSR”). The actual number of shares that vest at the end of each respective three-year period is determined based on the Company’s achievement of the three-year performance goals described above, as well as its TSR relative to the Russell 1000 Index over the same three-year performance period. Each reporting period, the Company reassesses the probability of achieving the performance and market conditions and determines whether it is probable that the performance and market conditions for the awards would be met. The Company recorded a total of approximately $5 million, $3 million and $3 million of stock-based compensation expense related to the performance-based restricted common stock awards with a market condition for the years ended December 31, 2017, 2016, and 2015, respectively. The Company expects to record estimated stock-based compensation expense related to the performance-based restricted common stock awards of approximately $6 million in aggregate over the periods 2018, 2019 and 2020.

Investments


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 considers all of its investments to be available-for-sale. The Company's investments consist of long-term variable rate debt instruments with an auction reset feature, referred to as auction rate securities. Investmentssecurities, and are classified as available-for-sale. The Company's auction rate security investments are carried at fair value. Changesvalue and any changes in unrealized holding gains and losses, net of the related tax effect, on available-for-sale securities 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 available-for-sale securityinvestment 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 estimated inherent credit losses, and such losses have been within management’s expectations. The large size and widespread nature of the Company’s customer base and the Company’screates 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, 2017, 2016,2019, 2018, and 2015.2017. 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 its cash deposits in 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


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 of an allowance for doubtful accounts. When evaluating the adequacy of the allowance for doubtful accounts, the Company analyzes historical collection experience, changes in customer payment profiles and the aging of receivable balances, as well as current economic conditions, all of which may affect a customer’s ability to pay. 


Leases

On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases, later codified as Accounting Standards Codification ("ASC") 842 ("ASC 842"), using the modified retrospective method. For periods presented prior to the adoption date, the Company continues to follow its previous policy under ASC 840, Leases. For details about the Company’s lease policy prior to the adoption of ASC 842, 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.

The determination of whether an arrangement contains a lease and the classification of a lease, if applicable, is made at lease commencement, 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 considered 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. The ROU asset also includes any lease prepayments, offset by lease incentives. 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. Because the Company currently has no outstanding debt, the incremental borrowing rate for each lease is primarily based on publicly available information for companies within the same industry and with similar credit profiles as the Company. The rate is then adjusted for the impact of collateralization, the lease term and other specific terms included in the Company’s lease arrangements. The incremental borrowing rate is determined at lease commencement, or as of January 1, 2019 for operating leases in existence upon adoption of ASC 842. The incremental borrowing rate is subsequently reassessed upon a modification to the lease arrangement. ROU assets are subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets.

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 improvements Shorter of lease term or useful life
Computer hardware and softwareThree to five years
Furniture and office equipment Five to ten years
Vehicles Five to ten years
Computer hardware and softwareAircraft TwoTen to fivetwenty years



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.

Goodwill and Intangible Assets

Goodwill represents the excess of costs over the fair value of assets of acquired businesses. Goodwill is not amortized, but instead tested for impairment at least annually by each reporting unit. 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. 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 then 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 Company's 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 database technology, customer base and trade names and other intangible assets are related to the Company’s acquisitions (see Notes 6 and 7). Acquired database technology is amortized on a straight-line basis over periods ranging from three years to eight years. Acquired trade names and other intangible assets are amortized on a straight-line basis over periods ranging from three years to fifteen years. See Note 7 for further details on the reclassification of the acquired trade names recorded in connection with the LoopNet acquisition from an indefinite-lived intangible asset to a definite-lived intangible asset. Acquired intangible assets characterized as customer base consists of acquired customer contracts and the related customer relationships and are amortized over periods ranging from ten years to thirteen years. Acquired customer bases are typically amortized on an accelerated basis related to the expected economic benefit of the intangible asset. The cost of capitalized building photography is amortized on a straight-line basis over periods ranging from three years to five years. Intangible assets are reviewed for impairment at least annually, and more frequently whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

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 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.


AssetsAcquired technology and data, customer base assets, trade names and other intangible assets are related to the Company’s acquisitions (see Notes 4, 9 and 10). 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.

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 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 more frequently if an event or other circumstance indicates that the fair value of a reporting unit may be disposedbelow its carrying amount.

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. TheseTo the extent that debt is outstanding, these amounts are reflected in the 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. 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. The Company had capitalized debt issuance costs, net of amortization, of approximately $4 million and $7 million as of December 31, 2017 and 2016, respectively. The debt issuance costs are associated with our various previous credit agreements, and the current amended and restated 2017 Credit Agreement (the "2017 Credit Agreement").

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 incurred 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 make significant estimates and assumptions, especially with respect to intangible assets.assets and contingent liabilities. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customer bases, acquired database technology and acquired trade names, from a market participant's perspective, useful lives, royalty rates and discount rates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed. 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.

Recent Accounting Pronouncements


Recently Adopted Accounting Pronouncements


On January 1, 2019, the Company adopted ASU 2016-02, Leases, using the modified retrospective method which allows for the application of the transition provisions at the beginning of the period of adoption, rather than at the beginning of the earliest comparative period presented in these consolidated financial statements. As permitted by the guidance, the Company elected to retain the original lease classification and historical accounting for initial direct costs for leases existing prior to the adoption date and did not reassess contracts entered into prior to the adoption date for the existence of a lease. The Company also did not recognize ROU assets and lease liabilities for short-term leases, which are leases in existence as of the adoption date with an original term of twelve months or less.

As a result of the adoption of the standard, the Company recognized ROU assets of $116 million, including prepaid rent and deferred rent that was reclassified and recognized as of the adoption date as a component of the ROU assets, as well as lease

liabilities of $150 million on its consolidated balance sheet. The assets and liabilities recognized upon application of the transition provisions were primarily associated with existing office leases. The Company also recognized a cumulative-effect adjustment to beginning retained earnings of $12 million, net of tax, as of January 1, 2019, to recognize the remaining deferred gain on the sale-leaseback of the Company's corporate headquarters building, pursuant to the guidance in ASC 842.

In March 2016,December 2019, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements2019-12, Simplifying the Accounting for Income Taxes, which is intended to Employee Share-Based Payment Accounting, which simplifies severalsimplify various aspects of therelated to accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification of share-based payment transactions on the statement of cash flows. The guidance requires a company to (i) recognize all excess tax benefits and tax deficiencies as income tax expense or benefit in the statement of operations using a prospective transition method, (ii) recognize excess tax benefits in the current period regardless of whether the benefit reduces taxes payable using a modified retrospective transition method, and (iii) classify all excess tax benefits as operating activities within the statement of cash flows using either a prospective transition method or a retrospective transition method. The guidance also allows a company to (i) elect whether to estimate the number of share-based awards expected to vest or account for forfeitures when they occur, and (ii) withhold uptaxes.

RecentIn August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting Pronouncements Not Yet Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board (“IASB”) jointly issuedfor Implementation Costs Incurred in a new revenue recognition standard, Accounting Standards Update (“ASU) 2014-09, Revenue from Contracts with Customers (Topic 606)Cloud Computing Arrangement That Is a Service Contract. ASU 2018-15 requires a customer in a cloud computing arrangement that is designeda service contract to improve financial reporting by creating common recognitionfollow the internal-use software guidance for GAAPin ASC 350-40 to determine which implementation costs to defer and International Financial Reporting Standards (“IFRS”).recognize as an asset. This guidance provides a robust framework for addressing revenue issues, improves the comparability of revenue recognition practices across industries, provides useful information to users of financial statements through improved disclosure requirements and simplifies the presentation of financial statements. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequently, amendments to the new revenue recognition standard were issued to clarify numerous accounting topics, including, but not limited to (i) the implementation guidance on principal versus agent considerations, (ii) the identification of performance obligations, (iii) the licensing implementation guidance, (iv) the objective of the collectability criterion, (v) the application of the variable consideration guidance and modified retrospective transition method, (vi) the way in which impairment testing is performed and

(vii) the disclosure requirements for revenue recognized from performance obligations. This guidance permits the use of either a full retrospective method or a modified retrospective approach. The modified retrospective approach would be applied only to the most current period presented along with a cumulative-effect adjustment at the date of adoption. This guidance will be effective for annual reporting periods beginning after December 15, 2017, although companies may adopt the standard as early as annual reporting periodsfiscal years beginning after December 15, 2016,2019, including interim periods within that reporting period.

Under this adoption method, the Company will recognizehave a cumulative effect adjustment to retained earnings as of January 1, 2018 and will account for its contracts with customers under the new guidance prospectively beginning on January 1, 2018. The Company used several available practical expedients provided in the new guidance, including assessing contracts with similar terms and conditions on a “portfolio” basis. Basedmaterial impact on the Company’s preliminary analysis, the Company believes that the potential impact of adopting this guidance on reported revenue in any period will not be material. The primary impact of adopting the new guidance relates to the deferral of incremental costs of obtaining customer contracts which is primarily commission costs on new sales. Under existing guidance, the Company expensed all commission costs in the periods they were earned, whereas under the new guidance the Company will defer commission costs on new sales and amortize them on a straight-line basis over 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 renewals rates; and industry competition. The Company currently estimates that the cumulative effect of adoption will result in the recognition of deferred commission cost asset between $48 million to $58 million, net of appropriate taxes, as of January 1, 2018.

Beginning in 2018, the Company expects significant changes to its disclosed revenue recognition policies and practices, as well as to other related financial statement disclosures. These revised disclosures will be made in the Company’s first quarterly report in 2018.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations’ accounting for leases. The guidance requires a company to recognize lease assets and lease liabilities on the balance sheet, as well as disclose key information about leasing arrangements. This guidance is effective on a modified retrospective basis for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. Early application is permitted. The Company is currently evaluating the impact this guidance will have on itsCompany's financial statements and related disclosures, but expects that the adoption of this standard may result in a material increase in assets and liabilities on its consolidated balance sheets.disclosures.


In June 2016, the FASB issued ASU 2016-13, Financial Instruments - CreditInstruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is designed to provide financial statement users with more information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. When determining such expected credit losses, the guidance requires companies to apply a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.

The guidance indicates that when substantiallyCompany acquired all of the issued and outstanding equity interests of STR for a purchase price of $435 million. STR is a global provider of benchmarking and analytics for the hospitality industry. The combination of STR's and CoStar's offerings is expected to allow for the creation of valuable new and improved tools for industry participants. The Company applied the acquisition method to account for the STR transaction, which requires that assets acquired and liabilities assumed be recorded at their fair values as of the acquisition date.

The following table summarizes the amounts recorded for acquired assets and assumed liabilities recorded at their fair values as of the acquisition date (in thousands):
 
Preliminary:
October 22, 2019
Cash and cash equivalents$11,710

Deferred revenue(10,966)
Deferred tax liabilities(7,980)
Other assets and liabilities(4,815)
Fair value of identifiable net assets acquired$435,452


The net assets of STR were recorded at their estimated fair values. In valuing the acquired assets and assumed liabilities, fair value estimates were based primarily on future expected cash flows, market rate assumptions for contractual obligations and appropriate discount rates. The purchase price allocation is preliminary, subject to the final determination of net working capital as of the grossacquisition date and the Company's assessment of certain tax matters. The customer base assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set of assets is not a business. This guidance is effective on a prospective basis for annual reporting periods beginning after December 15, 2017, including interim periods withinincorporated significant assumptions that reporting period. The Company will adopt this guidance in the first quarter of 2018 and this guidance is not expected to havehad a material impact on the estimated fair value, such as discount rates, projected revenue growth rates, customer

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the STR acquisition includes but is not limited to: (i) the expected synergies and other benefits that the Company believes will result from combining its operations with STR's operations; and (ii) any intangible assets that do not qualify for separate recognition, such as the assembled workforce. Goodwill recorded in connection with this acquisition is not amortized, but is subject to an annual impairment test. Of the $261 million of goodwill recorded as part of the acquisition, $159 million and $102 million are associated with the Company's North America and International operating segments, respectively. The goodwill recognized in the North America operating segment is expected to be deductible for income tax purposes in future periods.

As part of the STR acquisition, the Company incurred $2 million of transaction costs. Additionally, the Company paid $15 million cash into a cash escrow account for deferred compensation for certain STR employees, to be paid to active employees after a defined one year period following the acquisition or when earlier terminated without cause or terminated for good reason. In the event some or all of those employees are not entitled to their retention bonus, the funds will be remitted to the seller. The Company is recognizing compensation expense for the deferred compensation over the one year post-combination period.

ForRent

On February 21, 2018, the Company acquired all of the issued and outstanding capital stock of DE Holdings, Inc., including its ForRent division ("ForRent"), a wholly owned subsidiary of Dominion Enterprises ("Seller"), for a purchase price of approximately $376 million. The purchase price was comprised of approximately $340 million in cash and 103,280 shares of Company common stock, valued at approximately $36 million. ForRent's primary service is digital advertising provided through a network of four multifamily websites. The acquisition has yielded increased revenue, significant cost synergies and an improved competitive position in the industry. The Company applied the acquisition method to account for the ForRent transaction, which requires that assets acquired and liabilities assumed be recorded at their fair values as of the acquisition date.

Fair value of identifiable net assets acquired$376,292


The net assets of ForRent were recorded at their estimated fair values. In valuing acquired assets and assumed liabilities, fair value estimates were based primarily on future expected cash flows, market rate assumptions for contractual obligations and appropriate discount rates. Measurement period adjustments related to the determination of working capital as of the acquisition date and recognized in 2018 were not material.

The acquired customer base for the acquisition is composed of acquired customer contracts and the related customer relationships, and has a weighted average estimated useful life of ten years. The acquired technology has an estimated useful life of three years. The acquired trade name has a weighted average estimated useful life of ten years. The acquired building photography had an estimated useful life of one year. Amortization of the acquired customer base is recognized on an accelerated basis related to the expected economic benefit of the intangible asset, while amortization of the acquired technology, acquired building photography and acquired trade names and other intangible assets is recognized on a straight-line basis over their respective estimated useful lives. Goodwill recorded in connection with this acquisition is not amortized, but is subject to an annual impairment test. The $267 million of goodwill recorded as part of the acquisition is associated with the Company's North America operating segment. $8 million of goodwill that was recognized is expected to be deductible for income tax purposes in future periods.

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the ForRent acquisition includes but is not limited to: (i) the expected synergies and other benefits that the Company believes will result from combining its operations with ForRent's operations; and (ii) any intangible assets that do not qualify for separate recognition, such as the assembled workforce.

Upon acquisition, the Company assessed the (i) probability of a contingent sales tax liability and (ii) a state uncertain income tax position liability due to apportionment factors, and recorded accruals of $6 million and $2 million, respectively. The Company could not determine the fair value for the pre-acquisition state sales tax liability and therefore estimated a liability in accordance with ASC 450, Contingencies, using a state-by-state assessment. The uncertain income tax position was determined in accordance with the provisions of ASC 740, Income Tax, and was recorded as part of the purchase price allocation. The Seller has provided an indemnity for tax liabilities related to periods prior to the acquisition. The Seller's indemnification obligation for sales taxes in the state of Texas is limited to approximately $2 million. The total sales tax and uncertain income tax indemnification assets established as of the acquisition date were $5 million and $2 million, respectively. $0.9 million and $0.5 million of the contingent sales tax liability and related disclosures.indemnification asset recognized as of the acquisition date were reversed during 2019 and 2018, respectively, upon expiration of the statute of limitations applicable to the contingent sales tax liability. $0.6 million and $0.9 million of the uncertain income tax position liability and related indemnification asset recognized as of the acquisition date were reversed during 2019 and 2018, respectively, upon expiration of the statute of limitations applicable to the uncertain income tax position.


As part of the ForRent acquisition, the Company incurred $3 million of transaction costs. Additionally, the Company paid $12 million cash into a cash escrow account for retention compensation for certain ForRent employees, payable if they remained employed by the Company for a defined six-month period following the acquisition or were earlier terminated without cause or resigned for good reason. In the event funds remained in the escrow account after the employees were compensated and the defined

Other Acquisitions

On June 12, 2019, the Company acquired Off Campus Partners, LLC ("OCP"), a provider of student housing marketplace content and technology to U.S. universities for $16 million. The purchase agreement required an initial payment of $14 million, net of cash acquired, at the time of closing, with the remainder of the purchase price payable one year following the acquisition date, subject to offset for indemnification claims or adjustments to the purchase price after final determination of closing net working capital. As part of the acquisition, the Company recorded goodwill and intangibles assets of $8 million and $9 million, respectively. The net assets of OCP were recorded at their estimated fair value. The estimated fair values are preliminary, subject to the Company's assessment of certain tax matters. Measurement period adjustments recognized in 2019 were not material.

On November 8, 2018, the Company acquired Cozy Services, Ltd. ("Cozy"), a provider of online rental solutions that provides a broad spectrum of services to both landlords and tenants, for $65 million, net of cash acquired. As part of the acquisition, the Company recorded goodwill and intangible assets of $52 million and $11 million, respectively. The net assets of Cozy were recorded at their estimated fair value. Measurement period adjustments recognized in 2019 were not material.

On October 12, 2018, the Company acquired Realla Ltd. ("Realla"), the operator of a commercial property listings and data management platform in the U.K. for £12 million ($15 million). The purchase agreement required an initial payment of £10 million ($13 million), net of cash acquired, at the time of closing, with the remainder of the purchase price paid one year following the acquisition date, subject to offset for claims under the purchase agreement. In connection with the acquisition, the Company recorded goodwill and intangible assets of £8 million ($10 million) and £4 million ($5 million), respectively. The net assets of Realla were recorded at their estimated fair value. Measurement period adjustments recognized in 2019 were not material.

Pro Forma Financial Information

The unaudited pro forma financial information presented below summarizes the combined results of operations for the Company, ForRent and STR as though the companies were combined as of January 1, 2017 and January 1, 2018, respectively. The impact of Realla, Cozy and OCP on the pro forma financial information was not material and therefore those acquisitions were not included. The unaudited pro forma financial information for all periods presented includes amortization charges from acquired intangible assets, retention compensation, as referenced above, and the related tax effects, along with certain other accounting effects, but excludes the impacts of any expected operational synergies. The unaudited pro forma financial information as presented below is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisitions of ForRent and STR had taken place on January 1, 2017 and January 1, 2018, respectively.

The unrealized losses on the Company’s investments as of December 31, 20172019 and 20162018 were generated primarily from changes in interest rates and ARS that failed to settle at auction, due to adverse conditions in the global credit markets. The losses are considered temporary, as the contractual terms of these investments do not permit the issuer to settle the security at a price less than the amortized cost of the investment. Because the Company does not intend to sell these instruments and it is not more likely than not that the Company will be required to sell these instruments prior to anticipated recovery, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired as of December 31, 20172019 and 2016.2018. See Note 46 for further discussion of the fair value of the Company’s financial assets.

4.FAIR VALUE

6.    FAIR VALUE

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.

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, 20172019, 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 with AA to AAA credit ratings 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, 2017.2019. See Note 35 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, 2017.2019. 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 modelmodels as of December 31, 20172019 and 20162018 was approximately 6%5% and 5%6%, respectively. 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, 20172019, the Company determined there was a0 decline in the fair value of its ARS investments of approximately $730,000. The decline was deemed to be a temporary impairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity.investments. In addition, while a majority of the ARS are currently rated AAA,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.

In the aggregate, the Company expects the future amortization expense for intangible assets existing as of December 31, 2017 for future periods2019 to be approximately $29$72 million, $24$61 million, $21$51 million, $20$45 million and $17$39 million for the years ending December 31, 2018, 2019, 2020, 2021, 2022, 2023 and 2022,2024, respectively.


Intangible assets are reviewed for impairment at least annually and more frequently whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. During the first quarter of 2016, the Company determined that the acquired trade names recorded in connection with the LoopNet acquisition on April 30, 2012 should be reclassified from an indefinite-lived intangible asset to a definite-lived intangible asset due to work being performed to integrate the backend systems of LoopNet and CoStar, which may result in a future re-branding effort if aspectsNaN impairments of the LoopNet and CoStar services are ultimately combined. The Company estimatedCompany's intangible assets were recognized during the fair value of the LoopNet trade names using the relief from royalty method and concluded that no impairment existed as of March 31, 2016. The Company estimated a useful life of fifteen years for the LoopNet trade names, which are being amortized on a straight-line basis.

8.LONG-TERM DEBT 

On April 1, 2014 (the “Closing Date”), the Company entered into the 2014 Credit Agreement by and among the Company, as Borrower, CoStar Realty Information, Inc., as Co-Borrower, the Lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as Administrative Agent. The 2014 Credit Agreement provided for a $400 million term loan and a $225 million revolving credit facility, each with a term of five years. The Company repaid the remaining balance of $310 million and accrued interest on its existing term loan under the 2014 Credit Agreement on October 19, 2017 from existing cash balances.

The revolving credit facility includes a subfacility for swingline loans of up to $10 million, and up to $10 million of the revolving credit facility is available for the issuance of letters of credit. The Company has an irrevocable standby letter of credit outstanding totaling $0.2 million as ofended December 31, 20172019, 2018 and December 31, 2016, which was required to secure its San Francisco office lease. The letter of credit was established in 2014 related to the San Francisco office lease, and automatically renews through January 31, 2025.2017.


The term loan was amortized in quarterly installments in amounts resulting in an annual amortization of 5% during each of the first, second and third years, 10% during the fourth year and 15% during the fifth year after the Closing Date, with the remainder payable at final maturity. The loans under the 2014 Credit Agreement bore interest, at the Company's option, either (i) during any interest period selected by the Company, at 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 2% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio (as defined in the 2014 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 0.5% and (z) LIBOR for a one-month interest period plus 1%, plus an initial spread of 1% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio of the Company. If an event of default occurred under the 2014 Credit Agreement, the interest rate on overdue amounts increased by 2% per annum. The obligations under the 2014 Credit Agreement were guaranteed by all material subsidiaries of the Company and were secured by a lien on substantially all of the assets of the Company and those of its material subsidiaries, in each case subject to certain exceptions, pursuant to security and guarantee documents entered into on the Closing Date.

11.    LONG-TERM DEBT

On October 19, 2017, the Company entered into an amended and restated credit agreement (the ‘‘2017 Credit Agreement’’), which amended and restated in its entirety the existingthen-existing credit agreement dated April 1, 2014 (the "2014 Credit Agreement.Agreement"). 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 2017 facility may be used for working capital and other general corporate purposes of the Company and its subsidiaries. In connection with the transaction, the Company incurred $4 million of issuance costs. Those costs along with the $5 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.

As of December 31, 20172019 and 20162018, a valuation allowance has been established for certain deferred tax assets due to the uncertainty of realization. The valuation allowance as of December 31, 20172019 and 20162018 includes an allowance for unrealized losses on ARS investments, foreign deferred tax assets and state net operating losses and tax credits. The valuation allowance for the deferred tax asset for unrealized losses on ARS has been recorded as an adjustment to accumulated other comprehensive loss.



F-32

COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company established the valuation allowance because it is more likely than not that a portion of the deferred tax asset for certain items will not be realized based on the weight of available evidence. A valuation allowance was established for the unrealized losses on securities as the Company has not historically generated capital gains, and it is uncertain whether the Company will generate sufficient capital gains in the future to absorb the capital losses. A valuation allowance was established for the foreign deferred tax assets due to the cumulative loss in recent years in those jurisdictions. The Company has not had sufficient taxable income historically to utilize the foreign deferred tax assets, and it is uncertain whether the Company will generate sufficient taxable income in the future to utilize the deferred tax assets. Similarly, the Company has established a valuation allowance for net operating losses and tax credits in certain states where it is uncertain whether the Company will generate sufficient taxable income to utilize the net operating losses and tax credits before they expire.


The Company’s change in valuation allowance was an increasea decrease of approximately $4$0.7 million for the year ended December 31, 20172019 and a decreasean increase of approximately $1 million for the year ended December 31, 2016.2018. The decrease for the year ended December 31, 2019 is due to a decrease in foreign net operating loss deferred tax assets for which a full valuation allowance of approximately $1.1 million had been established, partially offset by an increase in the valuation allowance for state tax credits related to the D.C. qualified high technology company credit of approximately $0.4 million. The increase for the year ended December 31, 20172018 is due to an increase in the valuation allowance for foreign deferredstate tax assetscredits related to foreign net operating losses of approximately $4 million . The decrease for the year ended December 31, 2016 is due to a decrease in the valuation allowance for foreign deferred tax assetsD.C. qualified high technology company credit of approximately $1 million.


The Company had U.S. income before income taxes of approximately $403 million, $294 million and $167 million $135for the years ended December 31, 2019, 2018 and 2017, respectively. The Company had foreign losses before income taxes of approximately $12 million, ,$10 million, and $2 million for the years ended December 31, 2017, 20162019, 2018 and 2015, respectively. The Company had a foreign loss before income taxes of approximately $2 million for the year ended December 31, 2017.

Approximately $14$25 million and $1$22 million of the unrecognized tax benefits as of December 31, 20172019 and 2016,2018, respectively, would favorably affect the annual effective tax rate, if recognized in future periods. The increase for current year and prior year tax positions of $13$4 million for the year ended December 31, 20172019 is primarily attributable to research credits. The decrease for expiration of the statute of limitation of $1 million for the year ended December 31, 2019 is primarily attributable to a state apportionment methodology reserve. The Company recognized $72,000$0.2 million, $0.2 million, and $0.1 million for interest and penalties in its consolidated statement of operations for the yearyears ended December 31, 2017. The Company reversed interest and penalties of $416,000 in its consolidated statement of operations for the year ended December 31, 2016. The Company recognized $83,000 for interest and penalties in its consolidated statements of operations for the year ended December 31, 2015.2019, 2018, 2017 respectively.

The Company does not anticipate the amount of the unrecognized tax benefits will change significantly over the next twelve months.


The Company is subject to taxation in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company’s federal income tax returns for tax years 20112013 through 20162018 remain open to examination. The Company is under Internal Revenue Service examination for tax year 2013 related to the research and development credit. Most of the Company’s state income tax returns for tax years 20142016 through 20162018 remain open to examination.

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. 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 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under Accounting Standards Codification Topic 740, ("ASC 740"). In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

In connection with the Company's initial analysis of the impact of the Tax Act, the Company recorded a provisional discrete net tax benefit of $7 million in the period ending December 31, 2017. This net benefit primarily consists of a net benefit for the corporate tax rate reduction of $7.4 million and a net expense for the repatriation tax of $400,000. For various reasons, the Company has not completed its accounting for the income tax effects of certain elements of the Tax Act. The Company was able to make reasonable estimates of the effects of elementsbelieves that an adequate provision has been made for which the Company's analysis is not yet complete and recorded provisional adjustments. As the Company completes its analysis of the Tax Act, collects and prepares necessary data, and interprets any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, the Company may make adjustments to the provisional amounts. Those adjustments may materially impact the provision for income taxes in the period in which the adjustments are made.

Global intangible low taxed income (GILTI): Due to the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to 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's selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing its global income to determine whether it expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends on not only its current structure and estimated future results of global operations but also its intent and ability to modify its structure and/or its business, the Company is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, the Company has not made any adjustments related to potential GILTIthat may result from tax in its financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI.examinations.

Stock Incentive Plans


In April 2007, the Company’s Board of Directors adopted the CoStar Group, Inc. 2007 Stock Incentive Plan (as amended, the “2007 Plan”), subject to stockholder approval, which was obtained on June 7, 2007. In April 2016, the Company’s Board of Directors adopted the CoStar Group, Inc. 2016 Stock Incentive Plan (as amended, the “2016 Plan”), subject to stockholder approval, which was obtained on June 9, 2016. All shares of common stock that were authorized for issuance under the 2007 Plan that, as of June 9, 2016, remained available for issuance under the 2007 Plan (excluding shares subject to outstanding awards) were rolled into the 2016 Plan and, as of that date, no0 shares of common stock were available for new awards under the 2007 Plan. The 2007 Plan continues to govern unexercised and unexpired awards issued under the 2007 Plan prior to June 9, 2016. The 2007 Plan provided 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 2007 Plan could be incentive or non-qualified, and except in limited circumstances related to a merger or other acquisition, the exercise price for a stock option may not be less than the fair market value of the Company’s common stock on the date of grant. The vesting period of the options, restricted stock and restricted stock unit grants under the 2007 Plan was determined by the Board of Directors or a committee thereof and was generally three to four years. 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/or reserved the following shares of common stock for issuance under the 2016 Plan: (a) 1,450,000 shares of common stock, plus (b) 815,464 shares of common stock that were authorized for issuance under the 2007 Plan that, as of June 9, 2016, 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) any shares of common stock subject to outstanding awards under the 2007 Plan as of June 9, 2016, that on or after such date cease for any reason to be subject to such awards (other than by reason of exercise or settlement of the awards to the extent they are exercised for or settled in vested and nonforfeitable shares). 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 2 million shares were available for future grant under the 2016 Plan as of December 31, 2017.2019.


At December 31, 2017,2019, there was approximately $57$82 million of unrecognized compensation cost related to stock incentive plans, net of estimated forfeitures, which the Company expects to recognize over a weighted-average-period of 2.22.5 years.

The aggregate intrinsic value is calculated as the difference between (i) the closing price of the common stock at the end of the period and (ii) the exercise prices of the underlying awards, multiplied by the shares underlying options as of the end of the period that had an exercise price less than the closing price on that date. Options to purchase 81,815, 29,285,116,918, 177,299, and 59,60281,815, shares were exercised during the years ended 2017, 2016,2019, 2018 and 2015,2017, respectively. The aggregate intrinsic value of options exercised, determined as of the date of option exercise, was approximately $13$40 million, $3$45 million and $7$13 million for the years ended December 31, 2019, 2018 and 2017, 2016, and 2015, respectively.

The expected dividend yield is determined based on the Company's past cash dividend history and anticipated future cash dividend payments. The Company has never declared or paid any dividends on its common stock and does not anticipate paying any dividends on its common stock during the foreseeable future, but intends to retain any earnings for future growth of its business. Expected volatility is calculated based on historical volatility of the daily closing price of the Company's common stock over a period consistent with the expected life of the options granted. The risk-free interest rate is based on the U.S. Treasury rate with terms similar to the expected life of the options granted. The expected life for the options is determined based on multiple factors, including historical employee behavior patterns of exercising options and post-employment termination behavior as well as expected future employee option exercise patterns.

In March 2017, March 2016, and March 2015, 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 foregoing 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 support the Company’s goals 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.


These grantsThe vesting of restricted common stock areis subject to continuing employment requirements andrequirements. Certain performance-based restricted common stock awards are also subject to a market condition. Thecondition such that the actual number of shares that vest at the end of the respective three-year period is determined based on the Company’s achievement of the three-year performance goals described above, as well as itsand an established Company specific TSR factor relative to the Russell 1000 Index over the same three-year performance period. 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

The Company estimates the fair value of its performance-based restricted common stockequity awards with both a performance and market condition on the date of grant using a Monte-Carlo simulation valuation model. This pricing model uses multiple simulations to evaluate the probability of achieving the Company achieving various stock price levelsmarket condition to determinecalculate the expected TSR performance ranking.fair value of the awards. Expense is only recorded for awards that are expected to vest, net of estimated forfeitures. The assumptions used to estimate the fair value of performance-based restricted common stock awards with both a performance and a market condition granted were as follows:

The expected dividend yield is determined based on the Company's past cash dividend history and anticipated future cash dividend payments. The Company has never declared or paid any dividends on its common stock and does not anticipate paying any dividends on its common stock during the foreseeable future, but intends to retain any earnings for future growth of its business. Expected volatility is calculated based on historical volatility of the daily closing price of the common stock of the companies within the Russell 1000 Index over a period consistent with the expected life of the performance-based restricted common stock awards with a market condition. The risk-free interest rate is based on the U.S. Treasury rate with terms similar to the expected life of the performance-based restricted common stock awards with a market condition. The expected life is consistent with the performance measurement period of the performance-based restricted common stock awards with a market condition.


As of December 31, 2017,2019, the Company reassessed the probability of achieving the performance and market conditions and determined that it was probable that the performance goals associated with restricted stock awards with performance and market conditions for thegranted during 2019, 2018 and 2017 2016 and 2015 performance-based restricted common stock awards would be met by their forfeiture dates. As a result, theThe Company recorded a total of approximately $8 million, $5 million $3 million, and $3$5 million of stock-based compensation expense related to the performance-based restricted common stock awards with a market condition for the years ended December 31, 2019, 2018 and 2017, 2016 and 2015, respectively. TheAs of December 31, 2019, the Company expects to record an aggregate amount of stock-based compensation expense related to the performance-basedof approximately $11 million for restricted common stock awards of approximately $6 millionwith a market condition over the periods 2018, 20192020, 2021 and 2020.2022.

Management Stock Purchase Plan

The Board of Directors adopted the Company’s Management Stock Purchase Plan in December 2017 with the intent of providing selected key employees of the Company and its subsidiaries, including the Company's executive officers, the opportunity to defer a portion of their cash incentive compensation and to align management and stockholder interests through awards of Deferred Stock Units (“DSUs”) under the MSPP and awards of Matching RSUs issued under the Company 2016 Plan. Under this plan, participants are permitted to elect to defer up to 100% of their annual incentive bonus or commissions earned during the year by submitting an irrevocable election in accordance with Section 409A of the Internal Revenue Code, as amended. On the date the incentive bonus or commission would otherwise be paid in cash (typically during the following calendar year), the Company awards the participant DSUs representing the number of shares of common stock with an aggregate fair market value on that date equal to the amount of compensation elected to be deferred under the MSPP. On the same date the DSUs are awarded, the participant receives a grant of Matching RSUs covering the number of shares of common stock equal up to 100% of the DSUs granted. The expense related to the DSUs is recognized on a straight-line basis during the period that the related incentive bonus or commission is earned. The stock-based compensation expense for 7,441 DSUs awarded during 2019 was fully recognized as of December 31, 2018. The expense related to the Matching RSUs is recognized over the four years vesting period following the grant date.
