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.  We  have  created  and  compiled  a  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.  With  our  recent  acquisition  of  Homesnap, 
Inc., (“Homesnap”) we also offer an online mobile software platform for residential real estate agents and brokers.

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 hospitality industry. On June 24, 2020, we acquired Ten-X Holding 
Company, Inc. and its subsidiaries ("Ten-X"), which operate an online auction platform for commercial real estate. On October 
26, 2020, we acquired Emporis GmbH, a Germany-based provider of international commercial real estate data and images, and 
on December 22, 2020, we acquired Homesnap. See Notes 5 and 9 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 the Homesnap acquisition.

Strategy

Our strategy is to provide real estate industry professionals and consumers with critical knowledge to explore and complete 
transactions by offering the most comprehensive, timely and standardized information on real estate 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 real estate 
information, analytics and online marketplaces in an effort to continue to meet the needs of the industry as it grows and evolves.

Our standardized platform includes the most comprehensive proprietary database of commercial real estate information 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.  Our  database  has  been 
developed and enhanced for more than 30 years by a research department that makes thousands of daily database updates. In 
addition  to  our  internal  efforts  to  grow  the  database,  we  have  obtained  and  assimilated  a  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  and  our  auction  platform.  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.

We deliver our comprehensive commercial real estate information content to our U.S. and European customers primarily 
via an integrated suite of online service offerings that includes information about space available for-lease, comparable sales 

5

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, as 
well as a commercial real estate auction platform. We strive to cross-sell our services to our customers in order to best suit their 
needs.

Information about our revenues, long-lived assets and total assets derived from and located in foreign countries is included 
in  Notes  2,  3  and  14  of  the  Notes  to  Consolidated  Financial  Statements  included  in  this  Annual  Report  on  Form  10-K. 
Revenues; net income 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  Notes  3  and  14  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” in this Annual Report on Form 10-K.

Our primary brands include CoStar®, LoopNet®, Apartments.comTM, STR®, Ten-X®, BizBuySell®, LandsofAmericaTM, 
and HomeSnap®, which are accessible via the Internet and through our mobile applications. Our subscription-based services 
consist primarily of CoStar Suite® services, which include information, analytics and online marketplace services offered to the 
commercial real estate industry and related professionals. CoStar Suite® is sold as a platform of service offerings consisting of 
CoStar Property Professional®, CoStar COMPS Professional® and CoStar Tenant®, and is our largest service offering in our 
North America and International operating segments.

LoopNet® is the flagship brand in our network of commercial real estate marketing sites, which also includes Cityfeet.com 
and Showcase.com. Our LoopNet online marketplace enables commercial property owners, landlords, and brokers to advertise 
properties  for-sale  or  for-lease  and  to  submit  detailed  information  about  property  listings.  Commercial  real  estate  agents, 
buyers, investors, and tenants use LoopNet extensively to search for available property listings that meet their criteria. LoopNet 
offers unique, subscription-based advertising solutions for different segments within the industry and delivers value across its 
constituent  networks.  The  LoopNet  network  leverages  CoStar’s  commercial  real  estate  database  to  provide  in-depth  and 
accurate  information  across  all  commercial  property  types,  including  office,  industrial,  retail,  restaurant,  shopping  center, 
multifamily, specialty, health care, hospitality, sports and entertainment, land, and residential income. Investors and tenants are 
also able to consume industry news developed by our in-house editorial team.

We are consolidating STR data and services with CoStar Suite to create an integrated platform, which is expected to allow 
us to create valuable new and improved tools for industry participants. We are also working on integrating the Ten-X platform 
into both LoopNet and CoStar, to expand the audience for Ten-X auctions to include our online commercial real estate users.

Apartments.comTM  is  the  flagship  brand  in  our  network  of  apartment  marketing  sites,  which  also  includes 
ForRent.com®,  ApartmentHomeLiving.comTM,  WestsideRentals.com®,  AFTER55.com®, 
ApartmentFinder.comTM, 
CorporateHousing.comTM,  ForRentUniversity.com®,  Apartamentos.comTM,  which 
is  our  apartment-listing  site  offered 
exclusively  in  Spanish,  and  OffCampusPartners.com,  which  provides  student  housing  marketplace  content  and  powers  off 
campus  housing  sites  for  many  universities  across  the  U.S.  Our  apartment  marketing  network  of  subscription-based  services 
offers  renters  a  searchable  database  of  apartment  listings  and  provides  property  owners,  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 and is designed to meet renter preferences 
and  demands,  in  order  to  drive  traffic  to  those  sites  and  attract  advertisers  who  prefer  to  advertise  on  heavily  trafficked 
apartment websites. Our network of apartment marketing sites provides 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, we have sites that also offer innovative 
search tools such as the PolygonTM Search tool, which allow renters to specifically define the area in which they want to find an 
apartment and Plan Commute tools, which allow renters to search property listings that meet their transportation needs. We also 
offer complementary services to the rental industry, including the ability for renters to apply for rentals online, and for landlords 
to receive applications, screen tenants, and process rental payments and lease renewals.

Our BizBuySell services, which include BizQuest® and FindaFranchise, provide an online marketplace for businesses and 
franchises  for-sale.  Our  LandsofAmerica  services,  which  include  LandAndFarm  and  LandWatch®,  provide  an  online 
marketplace for rural lands for-sale and are also accessible via our Land.com domain.

We also provide other services that complement those offered through our primary brands. These include real estate and 
lease  management  solutions,  lease  administration,  lease  accounting  and  abstraction  services,  through  our  CoStar  Real  Estate 
Manager service offerings; market research, consulting and analysis, portfolio and debt analysis, and management and reporting 

6

capabilities  through  our  CoStar  Investment  Analysis  and  CoStar  Risk  Analytics  service  offerings;  and  benchmarking  and 
analytics for the hospitality industry through our STR offerings.

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. Auction transaction fees from our newly acquired online auction platform, Ten-X, are 
generally  charged  upon  the  successful  closure  of  an  auction  as  a  percentage  of  the  winning  buyer's  offer  price  for  the 
commercial real estate property sold. 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 expanded and continue to expand the coverage and depth of our information, analytics and online marketplace 
services. In addition to organic growth, we have grown our business through strategic acquisitions. Most recently, on June 24, 
2020,  we  acquired  Ten-X,  which  operates  an  online  auction  platform  for  commercial  real  estate;  on  October  26,  2020,  we 
acquired  Emporis  GmbH,  a  Germany-based  provider  of  international  commercial  real  estate  data  and  images,  which  we 
subsequently  merged  into  another  of  our  German  subsidiaries;  and  on  December  22,  2020,  we  acquired  Homesnap,  which 
operates an online mobile software platform for residential real estate agents and brokers. We continue to integrate our recent 
acquisitions  and  the  services  they  offer  into  our  CoStar  network.  See  Notes  5  and  9  to  the  accompanying  Notes  to  the 
Consolidated  Financial  Statements  included  in  Part  IV  of  this  Annual  Report  on  Form  10-K  for  further  discussion  of  these 
acquisitions.

Development, Investments and Expansion

We  are  committed  to  supporting,  improving  and  enhancing  our  information,  analytics  and  online  marketplace  solutions, 
including expanding and improving our offerings for property owners, property managers, brokers, agents, buyers, commercial 
tenants and residential 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.

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. 
However,  we  cannot  predict  with  certainty  the  amount  or  timing  of  any  reductions  in  revenues  and  earnings  or  subsequent 
increases in revenues and earnings, if any, resulting from the elimination or phasing out of any service offering.

We  are  consolidating  STR  hospitality  data  and  benchmarking  and  analytics  services  with  CoStar  Suite  to  create  an 
integrated platform. We expect that the combination of STR's and CoStar's offerings will allow us to create valuable new and 
improved tools for commercial real estate industry participants. 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  we  serve.  We  are 
working on integrating the Ten-X platform into both the LoopNet and CoStar service offerings, to expand the audience for Ten-
X auctions to include our online commercial real estate users. To increase exposure, we have upgraded LoopNet listings for 
properties to be auctioned on Ten-X and are allocating banner space on both our CoStar and LoopNet sites to Ten-X to cross-
market our services. We are beginning to incorporate recently acquired Emporis commercial real estate data and images into 
CoStar, and our Homesnap team is creating new and improved tools to help agents promote their residential listings, connect 
with buyers and sellers and streamline their daily workflow.

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, and plan to continue to invest in, evaluate and strategically position our sales force as the 
Company  continues  to  develop  and  grow.  Specifically,  we  continue  to  invest  in  marketing  our  services,  as  well  as  in  our 
research operations to support continued growth of our information and analytics offerings to meet the growing content needs 
of  our  clients.  Starting  in  2019  and  continuing  throughout  2020,  we  increased  our  investment  in  Apartments.com  marketing. 
We plan to continue to utilize a multi-channel marketing campaign and to work to determine the optimal level of marketing 
investment for our services for future periods. While we believe the investments we make in our business create a platform for 
growth, those investments may reduce our profitability and adversely affect our near-term financial position.

To  support  our  continued  expansion  and  development,  in  2020  we  completed  a  public  equity  offering,  a  Senior  Notes 
offering  and  the  refinancing  of  our  revolving  credit  facility.  For  additional  discussion  of  our  public  equity  offering,  Senior 
Notes offering and refinancing of our revolving credit facility, please see "Management's Discussion and Analysis of Financial 
Condition  and  Results  of  Operations“—Overview—Development,  Investments  and  Expansion"  and  Notes  11  and  15  to  the 
accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K.

Industry Overview

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

of the services we provide in order to obtain information they need to conduct their businesses, including:

• Sales and leasing brokers
• Property owners

• Property managers

• Government agencies
• Mortgage-backed security issuers

• Appraisers

• Design and construction professionals

• Pension fund managers

• Real estate developers

• Reporters

• Real estate investment trust managers

• Tenant vendors

•

Investment and commercial bankers

• Building services vendors

• Mortgage bankers
• Mortgage brokers
• Retailers

• Hospitality owners

• Real estate agents

• Communications providers

•
•

•

Insurance companies’ managers

Institutional advisors

Investors 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 efforts 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.

8

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.

The  apartment  rental  advertising  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  we  own  and  operate.  Many  apartment  ILS  websites  feature  only  the  rental  availabilities  that  larger  property 
owners  pay  to  advertise,  resulting  in  a  poor  user  experience  in  which  the  renter’s  search  criteria  return  either  limited  or  no 
results, irrelevant results or stale results that do not represent actual availabilities.

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

CoStar’s Comprehensive Database

CoStar  has  spent  more  than  30  years  building  and  acquiring  databases  of  commercial  real  estate  information,  which 
includes information on leasing, sales, comparable sales, tenants, and demand statistics, as well as digital images. This highly 
complex  database  is  comprised  of  hundreds  of  data  fields,  tracking  such  categories  as  location,  site  and  zoning  information, 
building  characteristics,  space  and  unit  availability,  tax  assessments,  ownership,  sales  and  lease  comparables,  space 
requirements, number of retail stores, number of listings, mortgage and deed information, for-sale and for-lease listings, income 
and  expense  histories,  tenant  names,  lease  expirations,  contact  information,  historical  trends,  demographic  information  and 
retail sales per square foot. The database also includes building photographs, aerial photographs, 3D virtual tours, plat maps and 
floor plans.

CoStar Research

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 phone calls, e-mails and Internet updates, in addition to field inspections, public records review, 
news monitoring and 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, training our clients 
to use the CoStar products and handling their customer service questions, creating a "one touch" approach to customer care. As 
part  of  the  process,  researchers  use  to  update  records  in  our  database,  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 online tool, which we refer to as our Marketing 
Center, or directly to our researchers. 

CoStar's  field  research  effort  includes  physical  inspection  of  properties  in  order  to  research  new  availabilities,  find 
additional property inventory, new construction, collect tenant information, verify existing information, photograph properties 
and create high quality videos of interior spaces (including walk-through videos and 3D virtual tours), amenities and exterior 

9

features  of  properties.  CoStar  utilizes  high-tech,  field  research  vehicles  primarily  within  North  America  and  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  precisely  measure 
buildings and geo-code 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”  or  “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.  CoStar  also 
utilizes 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  U.S.  drone 
operators are Federal Aviation Administration certified and trained to capture aerial photographs and videos of commercial real 
estate.  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.

Data and Image Providers. We license a small portion of our data and images from public record providers and third-party 
data sources. 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.

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:

•
•
•

•

Calling our information sources on recently updated properties to re-verify information;
Performing periodic research audits and field checks to determine if we correctly canvassed buildings;
Providing training and retraining to our research professionals to ensure accurate and standardized data compilation; 
and
Compiling measurable performance metrics for research teams and managers for feedback on data quality.

Finally,  one  of  the  most  important  and  effective  quality  control  measures  we  rely  on  is  feedback  provided  by  the 

commercial real estate professionals using our data every day.

Sales and Marketing

Our  overall  sales  strategy  is  to  provide  optimal  service  to  our  existing  customers,  attract  new  clients  and  cross-sell  the 
numerous  solutions  we  have  to  offer.  Our  sales  teams  sell  multiple  products  and  are  primarily  located  in  field  sales  offices 
throughout the U.S., with others in Canada, the U.K., Spain, France, and Germany. Our inside sales teams are largely based in 
Washington, DC and Richmond, Virginia. Our inside sales professionals actively work lead lists, prospect for new customers 
and perform virtual product demonstrations. Our professionals utilize the Internet and remote presentation tools to convey the 
multiple  solutions  we  offer.  In  response  to  the  COVID-19  pandemic,  our  entire  sales  force  has  been  equipped  to  operate 
remotely.

13

 
Our local offices typically support field sales and field research operations within the markets in which they operate. This 
enables our clients to benefit from a local presence. Our field sales force has the primary front-line responsibility for customer 
service, ensuring client satisfaction and building long-term relationships. Our local offices act as hubs for training, sources of 
market insight, product feedback sessions and connecting industry participants.

We actively manage all client accounts with frequent meetings, trainings, and updates on new enhancements.  In 2020, we 
successfully implemented a number of important sales initiatives, focused on selling our products to brokers, property owners 
and lenders in the U.S. This focus will continue in 2021. Our initiatives to partner with brokers to provide value to property 
owners allowed us to successfully position LoopNet Ads as a valuable marketing solution for a property owner’s major risk, 
namely, the cost of vacant space and the resulting negative impact on valuation of the property or portfolio, a risk that has been 
significantly  magnified  as  a  result  of  the  COVID-19  pandemic.  Additionally,  we  worked  closely  with  clients  to  help  them 
navigate the unprecedented challenges brought on by the COVID-19 pandemic through relevant training initiatives and curated 
webinars. During the fourth quarter of 2020, we began establishing a dedicated LoopNet sales division. Both our field sales and 
LoopNet sales teams will continue to sell LoopNet solutions.

To generate brand awareness and site traffic for the Apartments.com network of rental websites, we utilize a multi-channel 
marketing  campaign  featuring  television  and  radio  ads,  online  and  digital  advertising  impressions,  streaming  audio  and 
podcasts,  social  media,  email,  public  relations  and  news  articles,  out-of-home  and  paid  search  marketing,  all  of  which  are 
reinforced  with  substantial  Search  Engine  Optimization  efforts.  We  plan  to  continue  to  utilize  these  marketing  methods  to 
generate  brand  awareness  and  site  traffic  for  the  Apartments.com  network  and  implement  similar  marketing  strategies  for 
LoopNet  and  Ten-X.  We  will  continue  to  work  to  determine  the  optimal  level  of  marketing  investment  for  each  of  these 
services for future periods.

Our  CoStar  U.K.  sales  force  continued  to  grow  our  existing  client  base,  and  trained  users  on  the  numerous  product 
enhancements  we  released  during  2019  and  2020.  In  Canada,  our  sales  representatives  were  focused  on  targeting  brokers, 
owners and lender prospects for subscribing to our suite of products.

We seek to make our services essential to our clients’ businesses. To encourage clients to use our services regularly, we 
generally  charge  a  fixed  monthly  amount  for  our  subscription-based  information  services  rather  than  fees  based  on  actual 
system  usage.  Contract  rates  for  subscription-based  services  are  generally  based  on  the  number  of  sites,  number  of  users, 
organization size, the client’s business focus, geography and the range of services subscribed for. Our marketing solutions are 
priced  by  exposure  levels,  the  number  of  properties/spaces  for-lease,  rent  or  sale  and  the  market  in  which  they  are  offered. 
Listings for customers who purchase packages with the highest level of exposure usually appear first in search results and offer 
the  richest  media  content  and  engagement  opportunities  for  tenants  searching  for  space,  renters  looking  for  an  apartment  or 
investors  seeking  an  opportunity.  Our  subscription  clients  generally  pay  contract  fees  on  a  monthly  basis,  but  in  some  cases 
may pay us on a quarterly or annual basis.

In 2020, in response to the COVID-19 pandemic, our primary marketing methods included: virtual service demonstrations; 
targeted  paid  digital  marketing;  retargeting  and  social  marketing;  direct  marketing  such  as  email;  communication  via  our 
corporate  website  and  news  services;  participation  in  virtual  trade  shows  and  industry  events;  virtual  Company-sponsored 
events;  client  referrals;  content  marketing  including  webinars,  seminars,  and  white  papers  and  other  company  newsletters 
distributed via email to our clients and prospects.

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

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

News has always been a valuable part of CoStar's core subscription offering. CoStar's award-winning news teams report on 
the  latest  deals  and  developments  across  our  markets,  keeping  subscribers  informed  and  driving  higher  usage  in  our  core 
product. In 2020, we enhanced our offerings, including producing a series of special reports on the impact of the COVID-19 
pandemic on the commercial real estate industry and working with our analyst team, added weekly video updates and periodic 
webinars to discuss key changes to national and local markets. We merged STR's Hotel News Now news service into CoStar 
News, giving CoStar subscribers direct access to STR's hospitality news and analysis, while expanding the real estate audience 
for STR. Similarly, following CoStar's acquisition of Ten-X, we launched news coverage of commercial real estate auctions, 
telling the stories of prominent properties up for bid, including those featured on Ten-X. We continued to build our newsletter 
franchise, adding one focused on the hospitality industry and another highlighting the best of our analyst reports. We created 
new features for our newsletters showcasing the best of CoStar's architectural photography and data graphics. Finally, the news 
team, working with CoStar's research group, now produces quarterly Power Broker stories recognizing the top deals in each of 
our U.S., U.K. and Canadian markets, increasing broker exposure in the marketplace.

Competition

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

•
•
•
•
•
•
•
•
•
•
•
•
•
•
•

Quality and depth of the underlying databases;
Quality and quantity of leads and leases delivered;
Ease of use, flexibility and functionality of the software;
Intuitiveness and appeal of the user interface;
Timeliness of the data, including listings;
Breadth of geographic coverage and services offered;
Completeness and accuracy of content;
Client service and support;
Perception that the service offered is the industry standard;
Price;
Effectiveness of marketing and sales efforts;
Proprietary nature of methodologies, databases and technical resources;
Vendor reputation;
Brand loyalty among customers; and
Capital resources.

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

•

•

•

•

Online marketing services, websites or data exchanges targeted to commercial real estate brokers, buyers and sellers of 
commercial  real  estate  properties,  insurance  companies,  mortgage  brokers  and  lenders,  such  as  Reed  Business 
Information  Limited  and  its  Estates  Gazette  and  Radius  Data  Exchange  products,  SquareFoot,  officespace.com, 
Brevitas,  Catylist  (now  a  part  of  Moody's),  42Floors,  Altus  Group  (Commercial  Property  Search),  Digsy,  Quantum 
Listing,  RealNex  MarketPlace,  TenantWise,  Rofo,  BuildingSearch.com,  CIMLS,  CompStak,  Rightmove,  Yardi 
(PropertyShark and CommercialCafe), CREXi, TotalCommercial.com, DebtX, Real Capital Markets, and VTS;

Publishers and distributors of information, analytics and marketing services, including regional providers and national 
print  publications,  such  as  CBRE  Economic  Advisors,  Marshall  &  Swift,  REIS  Network  (part  of  the  Moody's 
Analytics  Accelerator),  Real  Capital  Analytics,  Real  Capital  Markets,  Reonomy,  Yardi  Matrix,  RealPage  and  its 
Axiometrics business, Altus Insight and Altus RealNet (Canada);

Search engine and Internet listing services featuring apartments for rent, such as Google, Bing, Facebook Marketplace, 
ApartmentGuide.com,  Rent.com,  Rentals.com,  Zillow  Rentals,  Trulia  Rentals,  StreetEasy,  NakedApartments.com, 
HotPads.com,  MyNewPlace.com,  Zumper,  PadMapper,  Craigslist,  ApartmentList.com,  Move.com,  Realtor.com, 
Adobo, RadPad, RentJungle, RentCafe.com, RentHop, RentBerry, and ApartmentRatings;

Hospitality benchmarking and analytics services, such as Lodging Econometrics, Kalibri Labs, Travelclick, HotStats 
and Shigi Group (SnapShot);

• Online and mobile software application providers in the residential real estate industry, including Zillow, Redfin and 

Realtor.com, as well as agent marketing platforms and workflow providers;

15

•

•

•

•

•

Locally controlled real estate boards, exchanges or associations sponsoring property listing services and the companies 
with whom they partner, such as Catylist, the National Association of Realtors, CCIM Institute, Society of Industrial 
and Office Realtors, the Commercial Association of Realtors Data Services and AIR CRE;

Real  estate  portfolio  management  software  solutions,  such  as  Cougar  Software,  MRI  Software,  Altus,  RealPage, 
AppFolio and SiteCompli;

Real estate lease management and administration software solutions, such as Accruent, Tririga, Manhattan Software, 
Tango Analytics, Lease Accelerator, Visual Lease, Sequnetra, Lease Harbor and AMT Direct;

In-house research departments operated by commercial real estate brokers; and

Public 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.

Proprietary Rights

To protect our proprietary rights in our methodologies, database, software, trademarks and other intellectual property, we 

depend upon a combination of:

•

•
•
•
•
•

Trade  secret,  misappropriation,  unfair  competition,  copyright,  trademark,  computer  fraud,  database  protection  and 
other laws;
Registration of copyrights and trademarks;
Nondisclosure, noncompetition and other contractual provisions with employees and consultants;
License agreements with customers;
Patent protection; and
Technical measures.

16

We seek to protect our software’s source code, our database and our photography as trade secrets and under copyright law. 
Although copyright registration is not a prerequisite for copyright protection, we have filed for copyright registration for many 
of our databases, photographs, software and other materials. Under current U.S. copyright law, the arrangement and selection of 
data  may  be  protected,  but  the  actual  data  itself  may  not  be.  Certain  U.K.  database  protection  laws  provide  additional 
protections for our U.K. databases. We license our services under license agreements that grant our clients non-exclusive, non-
transferable  rights.  These  agreements  restrict  the  disclosure  and  use  of  our  information  and  prohibit  the  unauthorized 
reproduction or transfer of any of our proprietary information, methodologies or analytics.

We  also  attempt  to  protect  our  proprietary  databases,  our  trade  secrets  and  our  proprietary  information  through 
confidentiality  and  noncompetition  agreements  with  our  employees  and  consultants.  Our  services  also  include  technical 
measures  designed  to  detect,  discourage  and  prevent  unauthorized  access  to  and/or  copying  of  our  intellectual  property.  We 
have established an internal antipiracy team that uses fraud-detection technology to continually monitor use of our services to 
detect and prevent unauthorized access, and we actively prosecute individuals and firms that engage in this unlawful activity.

We maintain U.S. and international trademark registrations for CoStar’s core service names and proactively file U.S. and 
international trademark applications covering our new and planned service names. Our federally registered trademarks include 
CoStar®,  CoStar  Suite®,  CoStar  Property®,  CoStar  COMPS®,  CoStar  Tenant®,  CoStar  Lease  Analysis®,  LoopNet®, 
Showcase.com®, Cityfeet.com®, Apartments.com®, Lands of America®, Ten-X® and HomeSnap®, among many others.  In 
the  U.S.,  trademarks  are  generally  valid  as  long  as  they  are  in  use  and  have  not  been  found  to  be  generic.  We  consider  our 
trademarks in the aggregate to constitute a valuable asset.

In addition, we maintain a patent portfolio that protects certain of our systems and methodologies. We currently have one 
granted patent in the U.K., which expires in 2021, covering, among other things, certain of our field research methodologies, 
five patents in Canada, which expire in 2021 (2 patents) and 2036 (3 patents), covering, among other things, certain features of 
our field research methodologies and user interface features, and fifteen patents in the U.S. which expire in 2021 (2 patents), 
2022 (2 patents), 2025 (1 patent), 2032 (2 patents), 2036 (3 patents), 2037 (4 patents), and 2038 (1 patent), covering, among 
other things, certain features of our field research methodologies and user interface feature. We regard the rights protected by 
our  patents  as  valuable  to  our  business,  but  do  not  believe  that  our  business  is  materially  dependent  on  any  single  patent  or 
portfolio of patents as a whole.

Human Capital Resources

As of January 31, 2021, we employed 4,752 employees. U.S-based employees represent approximately 88% of the overall 
employee  population,  followed  by  10%  in  European  and  Asia-Pacific  and  Latin  American  countries,  and  2%  in  Canadian 
provinces. None of our employees are represented by a labor union. We have experienced no work stoppages. We believe that 
our  employee  relations  are  excellent.  As  is  common  with  many  German  companies,  employees  in  our  German  subsidiary, 
Thomas  Daily  GmbH,  have  elected  five  fellow  employees  to  form  a  Works  Council,  which  represents  our  employees  at  the 
location.  The  Works  Council  has  certain  co-determination  rights  and  rights  to  receive  information  from  us  and  engage  us  in 
discussions under applicable law.

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

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

We provide competitive pay and benefits to attract and retain high quality talent. In addition to base salaries, compensation 
may include annual bonuses, commissions, and equity awards. Employees may also participate in an Employee Stock Purchase 

17

Plan,  and  a  401(k)  Plan  with  a  company  match.  Our  comprehensive  set  of  health  and  wellness  benefits  are  affordable,  high 
quality and valuable to employees and their families. Employees have multiple choices for health plans, access to vision and 
dental benefits and may participate in our employee wellness program as well as our employee assistance program. Additional 
benefits  include  paid  time  off,  parental  bonding  leave,  college  savings  benefits,  tuition  reimbursement,  company-subsidized 
commuter benefits and access to mental health, tax, and legal services.

We  consider  the  health  and  wellbeing  of  our  employees,  clients,  and  communities  to  be  our  top  priority  during  the 
COVID-19  pandemic.  We  transitioned  from  in-office  to  remote  work  for  non-essential  employees  in  early  March  of  2020 
through the adoption of new, stable, and secure technologies to support employees in remaining fully productive while working 
remotely.  We  also  adopted  new  policies  and  procedures  to  ensure  safety,  which  currently  include  requirements  for  mask 
wearing  in  the  office  and  when  coming  into  contact  with  the  community.  We  provide  personal  protective  equipment  for  all 
employees, including face coverings, hand sanitizer, antibacterial surface sanitizer and other protective equipment as needed. In 
addition, our office space workstations have been redesigned and upgraded to allow for six feet of social distancing between 
them  and  include  physical  barrier  shielding.  HVAC  systems  in  our  offices  have  been  upgraded  with  enhanced  filtration, 
increased fresh air intake and ultraviolet lighting disinfection. We have also made a significant investment in commercial grade 
air  filtration  equipment  and  monitor  air  quality  in  majority  of  our  office  locations.  Finally,  all  high  contact  surfaces  in  our 
offices  are  cleaned  multiple  times  during  the  day  and  deep  cleaned  each  night.  We  also  provide  free  COVID-19  PCR  and 
antibody testing for our employees and their immediate household family members.

Risk Factors

Risks related to our business

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 marketplace services. Our 
subscription-based services generate the largest portion of our revenues. Our revenue may not grow, or could decrease, if we 
cannot  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 low or sell new services to 
existing  customers  as  a  result  of  several  factors,  including,  without  limitation:  economic  pressures;  the  business  failure  of 
current clients; customer decisions that they do not need our services or to use alternative services; customers’ and potential 
customers’  budgetary  constraints;  consolidation  in  the  real  estate  and/or  financial  services  industries;  data  quality;  technical 
problems;  competitive  pressures;  or  devaluation  of  the  local  currencies  of  international  customers  relative  to  the  U.S.  dollar 
which impairs the purchasing power of such customers. We compete against many other real estate information, analytics, and 
marketing service providers for business. If clients cancel services or decide not to renew their subscription agreements, and we 
do not sell new services to our existing clients or attract new clients, then our renewal rate, net new sales and revenues may 
decline or fail to meet expectations.

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

Developing new services and upgrades to services, as well as integrating and coordinating current services, imposes heavy 
burdens on our systems department, product development team, management and researchers. The processes are costly, and our 
efforts  to  develop,  integrate  and  enhance  our  services  may  not  be  successful.  In  addition,  launching  and  selling  a  new  or 
upgraded service puts additional strain on our sales and marketing resources. If we are unsuccessful in obtaining greater market 
share or in obtaining widespread adoption of new or upgraded services, we may not be able to offset the expenses associated 
with the development, launch and marketing of the new or upgraded service, which could have a material adverse effect on our 
financial results. For example, to generate brand awareness and site traffic for our Apartments.com network of rental websites, 
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, the cost of the campaign could have an adverse effect on our financial results.

In addition, as we integrate acquired businesses, we continue to assess which services we believe will best meet the needs 
of our customers. If we eliminate or phase out a service and are not able to offer and successfully market and sell an alternative 
service, our revenue may decrease, which could have a material adverse effect on our results of operations.

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

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

19

•
•
•
•

•

•
•
•

•

•

•

the length and severity of the pandemic;
the availability of vaccines to our employees and clients;
the negative impact on global and regional economies, credit markets and economic activity;
governmental, business and individual actions taken in response to the pandemic and the impact of those actions on 
global economic activity;
the impact of business disruptions and reductions in employment levels and the level of consumer confidence in the 
economy on our clients and the resulting impact on their demand for our services and solutions;
business consolidations or failures among businesses that we serve;
our clients’ ability to pay for our services and solutions and our ability to collect payment for services provided;
our ability to market, develop, provide, and train clients on the use of our services and solutions, including as a result 
of  our  employees  or  our  clients’  employees  working  remotely,  worker  absenteeism  or  decreased  productivity, 
quarantines, social distancing or other travel or health-related restrictions;
the  pace  and  extent  of  economic  recovery  following  the  COVID-19  pandemic,  including  recovery  in  the  real  estate 
industry in particular;
increased  costs  of  additional  safety  procedures  and  increased  technology-related  expenses  to  provide  for  business 
continuity; and
increased cyber security risk, data accessibility concerns and susceptibility to communication disruptions because our 
employees and employees of our clients are working remotely.

As a result of COVID-19 and its impact on global economic conditions, including the real estate industry, towards the end 
of  the  first  quarter  and  in  the  first  two  months  of  the  second  quarter  of  2020,  we  saw  an  increase  in  customer  requests  for 
cancellations or suspensions, a reduction in new customer sales, failures to pay and delays in payments of amounts owed to us. 
We may see additional requests as current economic conditions cause customers to reduce expenses and prolong the decision-
making  time  before  purchasing  third  party  services,  which  may  lead  to  fewer  of  our  services  being  purchased  or  service 
cancellations.  The  extent  and  duration  of  any  future  continued  weakening  of  the  economy  is  unknown,  and  there  can  be  no 
assurance that any of the governmental or private sector initiatives designed to strengthen the economy will be successful or 
available  to  us  and  our  customers  and,  if  successful,  when  the  benefits  will  be  seen.  We  expect  that  cancellations  or 
suspensions, reductions of services and failures to pay amounts due to us may increase at any time while the economic impact 
of  the  pandemic  and  the  response  to  the  pandemic  impacts  our  customer  base.  We  compete  against  many  other  real  estate 
information and marketing service providers for business. If cancellations, reductions of services and failures to pay increase 
and we are unable to offset the resulting decrease in revenue by increasing sales to new or existing customers, our revenues will 
decline and our profitability will be adversely affected.

As a business, we have experienced and may continue to experience challenges, including increased costs, as we have and 
continue to pivot our employees’ work locations and hours as deemed necessary to respond to COVID-19 to protect the health 
and  well-being  of  our  employees,  customers  and  community.  Any  actual  or  perceived  failure  to  comply  with  government 
orders,  rules,  laws  or  regulations  as  a  result  of  changes  in  our  operations  in  response  to  COVID-19  could  subject  us  to 
investigations, claims, fines and other penalties, which in turn could adversely affect our business.

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

A downturn or consolidation in the real estate industry may decrease customer demand for our services. The 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  due  to  the  impact  of  the  COVID-19 
pandemic or otherwise that negatively impact investment returns; excessive speculative new construction in localized markets 
resulting in increased vacancy rates and diminished rent growth; and unanticipated disasters and other adverse events such as 
slowing of the growth in the working age population resulting in reduced demand for all types of real estate. A downturn in the 
real estate market, including as a result of a decline in leasing activity and absorption rates 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 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 

20

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.

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 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 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  be  unable  to  increase  awareness  of  our  brands,  including  CoStar,  LoopNet,  Apartments.com,  BizBuySell, 
LandsofAmerica, STR, Ten-X and Homesnap, which could adversely affect our business. We rely heavily on our brands, which 
we  believe  are  key  assets  of  our  company.  Awareness  and  differentiation  of  our  brands  are  important  for  attracting  and 
expanding the number of users of, and subscribers to, our online marketplaces, such as LoopNet, the Apartments.com network 
of rental websites, CoStar Showcase, and the Land.com network of rural lands for-sale. We expect to continue to invest in sales 
and marketing in 2021 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  our  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. To increase our revenue 
growth, 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 operating margins may experience downward pressure in the short term as a result of these investments. Furthermore, our 
investments may not produce the expected results. If we are unable to successfully execute our investment strategy, we may 
experience decreases in our revenues and operating margins.

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

21

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  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 to provide services that users might view as superior to our offerings. 
Competitors may introduce different solutions that attract users away from our services or provide solutions similar to ours that 
have  the  advantage  of  better  branding  or  marketing  resources.  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.  Increased  competition  could  result  in  lower  revenues  and  higher 
expenses, which would reduce our profitability.

If real estate professionals or other advertisers reduce or cancel their advertising spending with us and we are unable to 
attract  new  advertisers,  our  operating  results  would  be  harmed.  Our  marketplace  businesses,  including  LoopNet,  the 
Apartments.com network of rental websites, and the Land.com network of rural lands 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:

•
•
•

•
•

Increasing the number of unique visitors to, and users of, our websites and mobile applications;
The quantity and quality of the leads that we provide to our advertisers;
The success of any marketing and product development efforts directed at attracting additional users and advertisers to 
our marketplaces;
Keeping pace with changes in technology and with our competitors; and
Offering 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.  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  are  not  able  to  successfully  identify,  finance,  integrate  and/or  manage  costs  related  to  acquisitions,  our  business 
operations  and  financial  position  could  be  adversely  affected.  We  have  expanded  our  markets  and  services  in  part  through 
acquisitions of complementary businesses, services, databases and technologies, and expect to continue to do so in the future. 
Our acquisition strategy depends on our ability to identify, and the availability of, suitable acquisition candidates. We are likely 
to  incur  costs  in  connection  with  proposed  acquisitions,  but  may  ultimately  be  unable  or  unwilling  to  consummate  any 
particular  proposed  transaction  for  various  reasons.  For  example,  the  FTC  recently  withheld  approval  for  our  proposed 
acquisition of RentPath, the purchase agreement was subsequently terminated, and we incurred a termination fee of $52 million. 
We are also likely to incur severance costs and other integration costs post-acquisition. Costs in connection with acquisitions 
and  integrations  may  be  higher  than  expected  and  could  adversely  affect  our  financial  condition,  results  of  operation  or 
prospects of the combined business. In addition, acquisitions involve numerous risks, including risks that we will not be able to 
realize or capitalize on synergies created through combinations; manage the integration of personnel and products or services; 
manage  the  integration  of  acquired  infrastructure  and  controls;  control  potential  increases  in  operating  costs;  manage 
geographically remote operations; maintain management’s attention on other business concerns and avoid potential disruptions 
in ongoing operations during an acquisition process or integration efforts; successfully enter markets and sectors in which we 
have either limited or no direct experience, including foreign markets whose practices, regulations or laws may pose increased 
risk;  and  retain  key  employees,  clients  or  vendors  and  other  business  partners  of  the  acquired  companies.  We  may  not 
successfully  integrate  acquired  businesses  or  assets  and  may  not  achieve  anticipated  benefits  of  an  acquisition,  including 
expected synergies.  For example, we may be unable to fully integrate STR, Ten-X and Homesnap with CoStar when and as 
expected.

22

We  are  subject  to  an  FTC  consent  order,  which  is  publicly  available  on  the  FTC's  website  at  http://www.ftc.gov/,  that, 
among  other  things,  requires  us  to  give  the  FTC  advance  notice  of  certain  acquisitions.  Compliance  with  this  order  could 
prevent  us  from  closing  certain  acquisitions  or  add  significant  time  and  cost  to  such  acquisitions,  ultimately  making  an 
acquisition prohibitive or preventing us from realizing its anticipated benefits.

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

As a result of our acquisitions, we had approximately $2.7 billion of goodwill and intangibles as of December 31, 2020. 
Future acquisitions may increase this amount. If we are required to recognize goodwill and intangibles impairment charges in 
the future, this would negatively affect our financial results in the periods of such charges, which may reduce our profitability.

Our actual or perceived failure to comply with privacy laws and standards could adversely affect our business, financial 
condition and results of operations. We depend on information technology networks and systems to process, transmit and store 
electronic information and to communicate among our locations around the world and with our clients and vendors. We collect, 
use and disclose personally identifiable information, such as names, addresses, phone numbers and email addresses. We collect, 
store  and  use  biometric  data  and  sensitive  or  confidential  transaction  and  account  information.  We  also  collect  personal 
information from tenants and landlords, including social security numbers, birthdates and financial information to facilitate the 
apartment  rental  application  and  payment  process  between  a  renter  and  property  manager.  As  a  result,  we  are  subject  to  a 
variety  of  state,  national,  and  international  laws  and  regulations  that  apply  to  the  collection,  use,  retention,  protection, 
disclosure, transfer and other processing of personal data, including the Fair Credit Reporting Act, the General Data Protection 
Regulation  (GDPR)  and  California  Consumer  Privacy  Act  (CCPA).  These  laws  and  regulations  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,  the  GDPR  introduced  new  data  protection  requirements  in  the  EU  and  imposes 
substantial  fines  for  breaches  of  the  data  protection  rules.  The  GDPR  increased  our  responsibility  and  liability  in  relation  to 
personal data that we process. Following the end of the Brexit transition on December 31, 2020, the EU and U.K. agreed, as 
part  of  a  wider  trade  deal,  a  further  transitional  period  at  least  another  four  months,  extendable  to  six  months,  during  which 
personal data may flow freely from the European Economic Area (the “EEA”) to the U.K.. During that period, the European 
Commission is considering whether to make an “adequacy decision” in favor of the U.K., finding that the U.K. offers protection 
of personal data equivalent to the EEA, which will allow data to continue to flow freely between the EEA and the U.K. On 
February  19,  2021,  the  European  Commission  published  draft  adequacy  decisions.  If  no  final  adequacy  decision  is  made  in 
favor of the U.K. before the end of the further transitional period, because transfers of personal data between an EEA country 
and the U.K. will be transfers to a “third country”, we may be required to put in place additional mechanisms in place to enable 
transfers of data from EEA countries to the U.K. to ensure compliance with the GDPR. 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 or alleged failure to comply with the rules arising from the GDPR and related national laws of EU 
member  states  or  the  U.K.,  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  materially  adversely  affect  our  reputation, 
business, financial condition, cash flows and results of operations. Compliance with any of the foregoing laws and regulations 
can be costly, can delay or impede the development of new products, and may require us to change the way we operate.

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

23

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  
efforts  to  prevent,  detect  and  respond  to  data  security  incidents,  may  not  be  effective.  Further,  the  security  measures  and 
procedures our customers, vendors and other users of our systems have in place to protect sensitive consumer data and other 
information may not be successful or sufficient to counter all data breaches, cyberattacks or system failures.

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

•
•
•
•
•
•
•
•
•

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, and
Result in significant contractual penalties or other payments as a result of third-party losses or claims.

In addition, any cyberattacks or data security breaches affecting companies that we acquire or our customers or vendors 
(including  data  center  and  cloud  computing  providers)  could  have  similar  negative  effects  on  our  business.  For  example,  In 
December  2020,  we  became  aware  that  one  of  our  vendors  providing  IT  infrastructure  management  software,  SolarWinds 
Corporation, had been compromised by cyberattacks. As of December 22, 2020, we had implemented the fully patched versions 
of the SolarWinds software and we took additional measures to block Internet connectivity to and from all SolarWinds' Orion 
servers. Although we have not identified any compromise of our IT systems due to the use of SolarWinds software to date, we 
continue  to  monitor  our  network  for  any  potential  impact  related  to  the  SolarWinds  cyberattack.  Any  breach  of  our  security 
measures or the loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential 
data  about  us  or  our  customers,  including  the  potential  loss  or  disclosure  of  such  information  or  data  as  a  result  of  the 
SolarWinds cyberattack, could result in litigation and potential liability for us, damage our brand and reputation or otherwise 
harm  our  business.  The  coverage  under  our  insurance  policies  may  not  be  adequate  to  reimburse  us  for  losses  caused  by 
security breaches.

24

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

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

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

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

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

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

Our operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to market 
cyclicality, each of which could negatively affect our stock price. The real estate market may be influenced by general economic 
conditions, economic cycles, seasonality and many other factors, which in turn may impact our financial results. The different 
sectors  of  the  large  and  fragmented  industry,  such  as  office,  industrial,  retail,  multifamily,  single  family  and  others,  are 
influenced differently by different factors, and have historically moved through economic cycles with different timing. As such, 
it is difficult to estimate the potential impact of economic cycles and conditions or seasonality from year-to-year on our overall 
operating results. We generally see higher sales of Apartments.com listing services during the peak summer rental season and 
higher CoStar Suite sales towards the end of the year, however sales fluctuate from year-to-year and may fluctuate more widely 
when  there  are  changes  in  general  economic  conditions  or  the  industry,  such  as  changes  resulting  from  the  COVID-19 

25

pandemic. In addition, we generally incur greater marketing expenses during the second quarter, which coincides with the peak 
season for apartment rentals. The timing of widely observed holidays and vacation periods, particularly slowdowns during the 
end-of-year  holiday  period,  and  availability  of  real  estate  agents  and  related  service  providers  during  these  periods,  could 
significantly  affect  our  quarterly  operating  results  during  that  period.  If  we  are  unable  to  adequately  respond  to  economic, 
seasonal  or  cyclical  conditions,  our  revenues,  expenses  and  operating  results  may  fluctuate  from  quarter  to  quarter.  Our 
operating results, revenues and expenses may fluctuate for many reasons, including those described in this paragraph and below 
and elsewhere in this Annual Report on Form 10-K:

•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•

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

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

Fluctuating foreign currencies may negatively impact our business, results of operations and financial position. A portion 
of our business is denominated in foreign currencies. 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. 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.  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.

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.

Changes  in  tax  laws,  regulations  or  fiscal  and  tax  policies  or  the  manner  of  their  interpretation  or  enforcement  could 
adversely impact our financial performance. New laws or regulations, or changes in existing laws or regulations, or the manner 
of their interpretation or enforcement, could increase our cost of doing business. For example, 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. During 2018, the Department of the Treasury 
issued certain guidance in the form of notices and proposed regulations with respect to several provisions of the new 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  business.  In  addition,  if  federal,  state,  local  or 

26

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.

We are subject to a number of risks related to acceptance of credit cards and debit cards and facilitation of other customer 

payments.

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

We  depend  on  processing  vendors  to  complete  credit  and  debit  card  transactions  and  Automated  Clearing  House  (ACH) 
payments,  both  for  payments  made  to  us  directly  for  our  services  and  for  payments  made  by  renters  to  landlords  using  our 
online leasing services. If we or any one or more of these service providers fail to maintain adequate systems for authorization 
and processing credit card payments, it could cause one or more of the major credit card companies to disallow our continued 
use of their payment products. Further, if we or any one or more of these service providers fail to maintain adequate systems for 
authorization  and  processing  of  credit,  debit,  ACH  or  similar  payments  or  if  any  such  service  provider  were  to  terminate  or 
modify its relationship with us unexpectedly, our ability to process those customer transactions would be adversely affected, 
which  could  decrease  sales,  discourage  customers  away  from  our  marketplace  services,  result  in  potential  legal  liability,  and 
harm our business and reputation. In addition, if the systems for the authorization and processing of credit card transactions fail 
to work properly and, as a result, we do not charge our customers’ credit cards on a timely basis or at all, our business, revenue, 
results of operations and financial condition could be harmed.     

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

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

Risks related to our data, intellectual property and listings

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.  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  be  subject  to  legal  claims  by  our  customers,  either  of  which  could 
result in lower revenues and higher expenses.

27

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

Effective  trademark,  trade  secret,  patent,  and  copyright  protection  may  not  be  available  in  every  country  in  which  we 
provide our services. 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. This risk 
will increase as we continue to expand our business into new international jurisdictions.

We  may  not  be  able  to  successfully  halt  the  operation  of  websites  that  aggregate  our  data,  as  well  as  data  from  other 
companies, or copycat websites that may misappropriate our data. Third parties may misappropriate our data through website 
scraping,  robots  or  other  means  and  aggregate  and  display  this  data  on  their  websites.  In  addition,  “copycat”  websites  may 
misappropriate data on our website and attempt to imitate our brands or the functionality of our website. We may not be able to 
detect  all  such  websites  in  a  timely  manner  and,  even  if  we  could,  technological  and  legal  measures  available  to  us  may  be 
insufficient to stop their operations and the misappropriation of our data. Any measures that we may take to enforce our rights 
could require us to expend significant financial or other resources. 

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, such as 
breach  of  laws  related  to  privacy  and  data  protection.  We  could  also  be  subject  to  claims  based  upon  the  content  that  is 
accessible  from  our  website  through  links  to  other  websites  or  information  on  our  website  supplied  by  third  parties.  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.  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.

If  we  are  unable  to  obtain  or  retain  listings  from  real  estate  brokers,  agents,  property  owners  and  apartment  property 
managers,  our  marketplace  services,  could  be  less  attractive  to  current  or  potential  customers,  which  could  reduce  our 
revenues. The value of our real estate marketplace services to our customers depends on our ability to increase the number of 
property listings provided and searches conducted. As the number of listings increases, so does the utility of a marketplace's 
search,  listing  and  marketing  services.  We  depend  substantially  on  brokers,  agents,  property  owners  and,  in  the  case  of 
apartment rentals, property managers to submit listings to our marketplaces. If these parties choose not to continue their listings 
with  us,  or  choose  to  list  them  with  a  competitor,  our  CRE  marketplace  services  could  be  less  attractive  to  other  real  estate 
industry  transaction  participants,  resulting  in  reduced  revenue.  Similarly,  the  value  and  utility  of  our  other  marketplaces, 
including the BizBuySell.com network of business for-sale websites, are also dependent on attracting and retaining listings.

Risks related to our international operations

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 

28

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 sometimes exceeds the 
profit generated from such expansion, which reduces our profitability and may adversely affect our financial position.

The economic effects of “Brexit” may affect relationships with existing and future customers and could have an adverse 
impact on our business and operating results. On June 23, 2016, the U.K. held a referendum in which British citizens approved 
an  exit  from  the  European  Union  (“E.U.”),  commonly  referred  to  as  “Brexit.”  On  January  31,  2020,  the  U.K.  officially 
withdrew from the E.U, beginning a transition period of negotiations between the British government and the E.U. and other 
governments.  On  December  24,  2020,  the  E.U.  and  the  U.K.  announced  they  had  entered  into  a  post-Brexit  deal  on  certain 
aspects of trade and other strategic and political issues. The impact of Brexit, the December 2020 post-Brexit agreement and the 
future  relationship  between  the  E.U.  and  the  U.K.,  including  terms  not  addressed  in  the  December  2020  agreement,  remain 
uncertain.  Such  uncertainty  could  cause  political  and  economic  uncertainty  in  the  U.K.  and  the  rest  of  Europe,  which  could 
harm our business and financial results. In particular, Brexit caused and could continue to cause significant volatility in global 
equity markets, currency exchange rates and other asset prices, including those related to real property. Brexit may also lead to 
divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate, and compliance with 
those laws and regulations may be cumbersome, difficult or costly. Further, Brexit may lead other E.U. member countries to 
consider  referendums  regarding  their  E.U.  membership.  We  cannot  yet  predict  the  future  implications  of  Brexit,  including 
whether  it  could  increase  our  cost  of  doing  business  or  otherwise  adversely  affect  our  financial  condition  or  results  of 
operations. The impact to us from Brexit may affect not only our U.K. operations but operations in other parts of the E.U.

Risks related to our indebtedness

We  have  a  significant  amount  of  indebtedness,  which  could  decrease  our  flexibility  and  adversely  affect  our  business, 
financial  condition,  and  results  of  operations.  As  of  December  31,  2020,  we  had  approximately  $1  billion  of  Senior  Notes 
outstanding and an additional approximately $750 million available to be drawn under the 2020 Credit Agreement. There can 
be no assurance that our future cash flows will be sufficient to make payments of interest or principal on the Senior Notes or 
any amounts due and payable under the 2020 Credit Agreement. If our cash flows and capital resources are insufficient to fund 
our debt service obligations, we could face substantial liquidity problems and could be forced to reduce or delay investments 
and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or 
refinance our indebtedness. We may not be able to effect any such alternative measures on commercially reasonable terms or at 
all,  and,  even  if  successful,  those  alternative  actions  may  not  allow  us  to  meet  our  scheduled  debt  service  obligations. 
Furthermore,  we  may  incur  substantial  additional  indebtedness,  including  secured  indebtedness,  and  if  we  incur  additional 
indebtedness or other liabilities, the related risks that we face could intensify.

The 2020 Credit Agreement contains customary restrictive covenants imposing operating and financial restrictions on us, 
including restrictions that may limit our ability to engage in acts that we believe may be in our long-term best interests. These 
covenants  restrict  our  ability  and  the  ability  of  our  domestic  subsidiaries  to,  among  other  things,  (i)  incur  additional 
indebtedness,  (ii)  incur  liens,  (iii)  pay  dividends  or  make  certain  other  restricted  payments,  investments  or  acquisitions,  (iv) 
merge or consolidate with another person, and (v) sell, assign, lease or otherwise dispose of all or substantially all of our assets. 
In addition, the 2020 Credit Agreement requires us to comply with a maintenance covenant that we will not exceed a total net 
leverage  ratio,  calculated  as  total  consolidated  debt,  net  of  up  to  $1.0  billion  of  unrestricted  cash  and  cash  equivalents,  to 
consolidated EBITDA, of 4.50 to 1.00. The operating restrictions and financial covenants in the 2020 Credit Agreement 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.

A breach of the covenants under the 2020 Credit Agreement or the indenture that governs the Senior Notes could result in 
an event of default under the applicable indebtedness. Such a default may allow the creditors to accelerate the related debt and 
may result in the acceleration of any other debt to which a cross-acceleration provision applies. In the event the holders of the 
Senior  Notes  or  our  other  debt  accelerate  the  repayment  of  our  borrowings,  we  and  our  subsidiaries  may  not  have  sufficient 
assets to repay that indebtedness.

Our borrowings under the 2020 Credit Agreement will carry a variable interest rate based on the Euro Interbank Offered 
Rate  (“EURIBOR”)  or  the  London  Interbank  Offered  Rate  (“LIBOR”)  as  a  benchmark  for  establishing  the  rate  of  interest. 
LIBOR  is  the  subject  of  recent  national,  international  and  other  regulatory  guidance  and  proposals  for  reform.  The  U.K. 
authority that regulates LIBOR announced that it will not compel banks to submit rates for the calculation of LIBOR after June 

29

2023.  The full impact of any transition away from LIBOR remains unclear. We may need or seek to negotiate with our lenders 
for  an  alternative  rate.  We  may  not  be  able  to  agree  with  our  lenders  on  a  replacement  reference  rate  that  is  as  favorable  as 
LIBOR, which may increase in the cost of our borrowings under the 2020 Credit Agreement.

Our indebtedness increases our vulnerability to general adverse economic and industry conditions; requires us to dedicate a 
portion of our cash flow from operations to payments on indebtedness, reducing the availability of cash flow to fund capital 
expenditures, marketing and other general corporate activities; limits our ability to borrow additional funds; and may limit our 
flexibility in planning for, or reacting to, changes in our business and the industries in which we operate.

A  lowering  or  withdrawal  of  the  ratings  assigned  to  our  debt  securities  by  rating  agencies  may  increase  our  future 
borrowing costs, reduce our access to capital or result in the loss of certain covenant suspensions. Our debt rating could be 
lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, future circumstances relating to the basis 
of the rating, such as adverse changes, warrant. Any future lowering of our ratings likely would make it more difficult or more 
expensive for us to obtain additional debt financing.

In  addition,  the  2020  Credit  Agreement  provides  that,  during  any  period  of  time  in  which  we  maintain  a  corporate 
investment grade rating from any two of Standard & Poor’s Rating Services, Fitch Ratings, Inc. or Moody’s Investors Services, 
Inc.  (such  period,  a  “Covenant  Suspension  Period”),  certain  customary  negative  and  affirmative  covenants  contained  in  the 
2020  Credit  Agreement  are  suspended,  including  the  covenants  restricting  affiliate  transactions,  incurrence  of  indebtedness, 
investments,  asset  sales  and  restricted  payments.  A  lowering  of  one  or  both  of  our  investment  grade  ratings  would  result  in 
increased compliance costs and would impose certain operating restrictions, either of which could be materially adverse to our 
operations and financial results.

Properties

Our  headquarters  is  located  at  1331  L  Street,  NW,  in  downtown  Washington,  DC,  where  we  occupy  approximately 
169,093 square feet of office space, with a lease that expires May 31, 2025 (with two 5-year renewal options). Our headquarters 
is used primarily by our North America operating segment. Our principal facility in the U.K. is located in London, where we 
occupy 23,064 square feet of office space. Our lease for this facility has a term ending August 31, 2025. This facility is used by 
our International operating segment.

We  also  operate  our  research  functions  out  of  leased  office  spaces  in  Richmond,  Virginia;  San  Diego,  California;  and 
Atlanta, Georgia. Additionally, we lease office space in a variety of other metropolitan areas. These locations include, among 
others, the following: Hendersonville, Tennessee; Irvine, California; Boston, Massachusetts; San Francisco, California; Ontario, 
California; and Los Angeles, California. 

We believe these facilities are suitable and appropriately support our business needs.

Item 3. 

Legal Proceedings

Currently, and from time to time, we are involved in litigation incidental to the conduct of our business, including, among 
others,  the  legal  actions  discussed  under  “Contingencies”  in  Note  13  “Commitments  and  Contingencies”  to  our  Financial 
Statements. While our management presently believes that the ultimate outcome of these proceedings, individually and in the 
aggregate, will not materially harm our business, financial position, future results of operations or liquidity, legal proceedings 
are  inherently  uncertain,  and  unfavorable  rulings  could,  individually  or  in  aggregate,  have  a  material  adverse  effect  on  our 
business, financial position, future results of operations or liquidity.

Selected Financial Data

Selected Financial Data
(in thousands, except per share data)

The  following  table  provides  selected  consolidated  financial  data  for  the  five  years  ended  December  31,  2020.  The 
consolidated statements of operations data shown below for each of the three years ended December 31, 2020, 2019 and 2018 
and  the  consolidated  balance  sheet  data  as  of  December  31,  2020  and  2019  are  derived  from  audited  consolidated  financial 
statements that are included in this report. The consolidated statements of operations data for each of the years ended 2017 and 
2016 and the consolidated balance sheet data as of December 31, 2018, 2017 and 2016 shown below are derived from audited 
consolidated financial statements for those years that are not included in this report. Information about prior period acquisitions 
and the adoption of recent accounting pronouncements that may affect the comparability of the selected financial information 
presented below are included in "Item 1. Business" and Note 2 to the Notes to the Consolidated Financial Statements included 
in  Part  IV  of  this  Annual  Report  on  Form  10-K.  The  total  assets  and  total  long-term  liabilities  reported  in  the  consolidated 
balance sheet data have been reclassified to conform to our current presentation as a result of the retrospective application of the 
authoritative guidance to simplify the presentation of debt issuance costs.

The  following  data  should  be  read  in  conjunction  with  “Item  7.  Management’s  Discussion  and  Analysis  of  Financial

Management’s Discussion and Analysis of Financial Condition and Results of Operations

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

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

Overview

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

service: 

Information and Analytics

CoStar Suite®. 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®,  CoStar  COMPS®,  CoStar  Market  Analytics,  CoStar 
Tenant®, CoStar Lease Comps and CoStar Public Record through our online and mobile applications. Our integrated suite of 
online service offerings 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, and industry news. Our commercial real estate sales 
force is currently responsible for selling multiple product lines, including CoStar Suite and LoopNet. Starting in late 2019, we 
shifted the focus of our sales force to sales of LoopNet Diamond, Platinum and Gold Ads. As a result of this shift, as well as the 
continued impact of COVID-19 on our current and potential customer base, we saw a decline in CoStar Suite revenue growth 
rates in 2020 compared to 2019 growth rates and expect similar growth rates throughout 2021.

Information services. We provide real estate and lease management technology solutions, including lease administration, 
lease accounting and abstraction services, through our CoStar Real Estate Manager® service offerings, as well as portfolio and 
debt  analysis,  management  and  reporting  capabilities  through  our  CoStar  Investment  Analysis  and  CoStar  Risk  Analytics® 
service offerings. On October 22, 2019, we acquired STR and we now also provide STR’s complementary benchmarking and 
analytics services to the hospitality industry. STR sells the majority of its services on a subscription basis, but also receives one-
time  or  ad  hoc  transaction  fee  revenues.  We  provide  information  services  internationally,  through  our  Grecam,  Belbex  and 
Thomas Daily businesses in France, Spain and Germany, respectively. The growth rates of information services increased in 
2020  compared  to  2019  primarily  due  to  the  STR  acquisition.  The  hospitality  industry  has  been  severely  impacted  by 
COVID-19, as a result, revenue for STR declined in the second quarter of 2020 and increased moderately during the remainder 
of the year. We anticipate STR revenue and overall information services growth rates to moderate during 2021.

Online Marketplaces

Multifamily.  Apartments.comTM  is  part  of  our  network  of  apartment  marketing  sites,  which  primarily  includes 
ApartmentFinder®, ForRent.com®, ApartmentHomeLiving.comTM, Apartamentos.comTM, Westside Rentals, and Off Campus 
Partners, LLC ("OCP"). Our network of subscription-based advertising services provides property management companies and 
landlords with a comprehensive advertising destination for their available rental units and offers renters a platform for searching 
for available rentals. During 2020, multifamily revenue growth rates generally continued to increase relative to 2019 revenue 
growth rates as tenants, property owners and landlords continued to transact in our digital environment. 

Commercial  property  and  land.  Our  LoopNet.com  network  of  commercial  real  estate  websites  offer  subscription-based, 
online marketplace services that enable commercial property owners, landlords and real estate agents working on their behalf to 
advertise  properties  for  sale  or  for  lease  and  to  submit  detailed  information  about  property  listings.  Commercial  real  estate 
agents, buyers and tenants use the LoopNet.com network of online marketplace services to search for available property listings 
that  meet  their  criteria.  On  June  24,  2020,  we  acquired  Ten-X,  an  online  auction  platform  for  commercial  real  estate.  On 

34

December  22,  2020,  we  acquired  Homesnap,  an  industry-leading  online  and  mobile  software  platform  that  provides  user-
friendly  applications  to  optimize  residential  real  estate  agent  workflow  and  reinforce  the  agent-client  relationship.  Our 
BizBuySell  network,  which  includes  BizQuest®  and  FindaFranchise,  and  our  Land.com  network  of  sites,  which  includes 
LandsofAmerica, LandAndFarm and LandWatch®, are also included in our commercial property and land service revenue. The 
BizBuySell  network  provides  online  marketplaces  for  businesses  for-sale  and  our  Land.com  network  of  sites  provide  online 
marketplaces  for  rural  lands  for-sale.  As  part  of  our  rebuild  and  launch  of  the  LoopNet  Diamond,  Platinum  and  Gold  Ads 
products during the fourth quarter of 2019, we shifted the focus of our commercial real estate sales force to LoopNet Ads. As a 
result, the LoopNet revenue growth rate increased in the fourth quarter of 2019. Growth was flat during the first half of 2020 as 
LoopNet.com sales volumes declined and cancellations increased as a result of COVID-19 and its impact on the commercial 
real estate industry. During the second half of 2020, we saw an increase in sales and expect LoopNet revenue growth rates to 
continue at those levels in 2021. Overall, revenues in commercial property and land increased during 2020 compared to 2019 
primarily due to revenue from our newly acquired online auction platform, Ten-X and, to a lesser extent, revenue growth from 
LoopNet.com.  Overall,  we  expect  an  increase  in  the  commercial  property  and  land  growth  rates  in  2021  compared  to  2020 
primarily due to the Homesnap acquisition and continued impact of the Ten-X acquisition.

Impact of the COVID-19 Pandemic

A  novel  strain  of  coronavirus  known  as  "COVID-19"  was  first  identified  in  Wuhan,  China  in  December  2019,  and  was 
subsequently declared a pandemic by the World Health Organization on March 11, 2020. COVID-19 has surfaced in nearly all 
regions around the world and resulted in travel restrictions and business slowdowns or shutdowns in affected areas. The full 
impact of the COVID-19 pandemic is unknown and is evolving as the pandemic continues. The COVID-19 pandemic did not 
materially affect our consolidated financial statements for the year ended December 31, 2020.

We are closely and continually monitoring the impact of the COVID-19 pandemic on our business, employees, customers, 
and communities. To protect the health and safety of our employees and to help stop the spread of the disease, we shifted to a 
digital,  remote  workplace  in  mid-March  2020.  As  of  that  time,  nearly  all  of  our  employees  began  to  work  from  home  and 
continue to do so as of the date of this filing. We have temporarily shifted certain employees’ job responsibilities so they can 
work  from  home  and  modified  our  in-person  research  and  sales  processes  so  that  they  can  be  conducted  safely  and  in 
compliance  with  social  distancing  guidelines  to  protect  our  employees,  our  customers  and  our  communities.  We  believe  our 
employees are operating at near normal levels of productivity in this digital environment. We continue to monitor events related 
to the pandemic, as well as the guidelines and mandates provided by governmental and health authorities. We plan to continue 
adapting our business operations when and as deemed appropriate to comply with these guidelines and mandates and to respond 
to changing circumstances.

In  connection  with  the  shift  to  work  from  home,  we  incurred  and  may  continue  to  incur  expenses  to  help  employees 
perform their jobs effectively and securely. In preparation for an eventual return to work in the office, we have also incurred 
and expect to continue to incur expenses to help protect the health and safety of our employees and visitors. In response to the 
COVID-19 pandemic, we have taken steps to manage our costs, including minimizing hiring to essential positions, restricting 
business  travel  and  canceling  in-person  marketing  events.  We  expect  to  continue  to  minimize  travel  and  restrict  in-person 
marketing events during the first half of 2021. Overall, the increased direct spend related to the COVID-19 pandemic, including 
office reconfiguration, has not been material to date and has had minimal impact on our financial position and operating results 
as these expenses have been generally offset by the cost savings described above. As the situation evolves, we may implement 
additional cost reductions.

Current  general  economic  conditions  in  the  U.S.  and  the  world  as  a  result  of  the  COVID-19  pandemic  are  negatively 
affecting business operations for our clients and are expected to result in business consolidations and, in certain circumstances, 
failures.  In  general,  customers  are  seeking  to  reduce  expenses  as  a  result  of  current  economic  conditions.  The  extent  and 
duration  of  any  future  continued  weakening  of  the  global  economy  is  unknown.  There  can  be  no  assurance  that  any  of  the 
governmental or private sector initiatives designed to strengthen the U.S. and other economies will ultimately be successful or 
available  to  us  and  our  customers,  and,  if  successful,  when  the  benefits  will  be  available  or  seen.  Because  of  the  rapidly 
evolving  nature  of  the  COVID-19  pandemic  and  responses  to  it  by,  and  the  impact  on,  global  economies,  our  revenue  or 
earnings forecasts may not prove to be accurate. Any expected changes in financial results discussed in this report, including 
any  expected  impact  of  COVID-19,  are  based  on  our  current  observations  and  experience  and  involve  estimates  and 
assumptions. As the extent and duration of the impacts from COVID-19 remain unclear, our estimates and assumptions may 
evolve  as  conditions  change.  Our  current  observations  and  past  experience  and  results  may  not  be  an  indicator  of  ongoing 
trends or future results, and actual results could differ significantly from our estimates and expectations.

Our near-term revenues are relatively predictable as a result of our subscription-based business model; however, we expect 
that we will continue to experience the effects of the COVID-19 pandemic on our business, results of operations and overall 

35

financial  performance.  Such  effects  may  include,  among  others,  a  decrease  in  new  customer  sales  and  increases  in  customer 
cancellations, suspensions, service reductions and failures to pay or delays in payments of amounts owed to us. We are more 
likely to incur asset impairment charges or restructuring charges, or further increase our allowance for credit losses, as a result 
of this crisis and related economic downturn, which could adversely affect our results of operations. The amount and frequency 
of such actions will be affected by the severity and duration of the COVID-19 pandemic. We experienced a decrease in net new 
bookings of subscription-based services and an increase in customer requests for cancellations and suspensions towards the end 
of the first quarter of 2020 that continued through May 2020; however, those requests have eased since then, and sales related 
to marketplace service offerings have returned to pre-pandemic levels. During 2020, we increased the allowance for credit loss 
as a result of increased write-off trends and increased the forecasted credit loss estimate on high credit risk customers to reflect 
the uncertainty around the duration and speed of an economic recovery in the first three quarters of 2020. However, the credit 
loss expense normalized in the fourth quarter of 2020. Due to the uncertainty associated with the COVID-19 pandemic, we will 
continue to monitor customer behavior and its impact on our results of operations. See Note 3 in this Annual Report on Form 
10-K for further discussion.

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

For the years ended December 31, 2020, 2019 and 2018 our annualized net new bookings of subscription-based services on 
all contracts were approximately $184 million, $210 million and $169 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.  We  recognize  subscription  revenues  on  a  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.

For the years ended December 31, 2020, 2019 and 2018, our contract renewal rate for existing CoStar subscription-based 
services on annual contracts was approximately 89%, 90% and 90% respectively, and, therefore, our cancellation rate for those 
services was approximately 11%, 10%, and 10%, 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 plan to continue to invest in our business and our services, evaluate strategic growth opportunities, and pursue our key 
priorities as described below, while we closely monitor the economic developments from the COVID-19 pandemic and manage 
our response to such developments. We are committed to supporting, improving and enhancing our information, analytics and 
online  marketplace  solutions,  including  expanding  and  improving  our  offerings  for  our  client  base  and  site  users,  including 
property  owners,  property  managers,  buyers,  commercial  tenants  and  residential  renters.  We  expect  to  continue  our  software 
development  efforts  to  improve  existing  services,  introduce  new  services,  integrate  and  cross-sell  services,  integrate  recently 
completed  acquisitions  and  expand  and  develop  supporting  technologies  for  our  research,  sales  and  marketing  organizations. 
We may reevaluate our priorities as the COVID-19 pandemic continues to evolve.

Our key priorities for 2021 currently include:

•

Integrating and developing service offerings of recently completed acquisitions, including STR, Ten-X and Homesnap, 
with our business operations. We are consolidating STR data and services with CoStar Suite to create an integrated 
platform.  We  expect  that  the  combination  of  STR's  and  CoStar's  offerings  will  allow  us  to  create  valuable  new  and 
improved  tools  for  industry  participants.  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  we  serve.  We  are 
working on integrating the Ten-X platform with both LoopNet and CoStar, to expand the audience for Ten-X auctions 
to  include  our  online  commercial  real  estate  users.  To  increase  exposure,  we  have  upgraded  LoopNet  listings  for 
properties to be auctioned on Ten-X and are allocating banner space on both our CoStar and LoopNet sites to Ten-X to 

36

•

•

cross-market  our  services.  Our  Homesnap  team  is  creating  new  and  improved  tools  to  help  agents  promote  their 
residential listings, connect with buyers and sellers and streamline their daily workflow.

Continuing to invest in the LoopNet marketplace and the Ten-X auction platform. We are enhancing the content on 
LoopNet.com  (including  high-quality  imagery),  seeking  targeted  advertisements,  providing  premium  listing  services 
(such  as  LoopNet  Diamond,  Platinum,  and  Gold  Ads)  that  increase  a  property  listing’s  exposure,  and  adding  more 
content for premium listings to better meet the needs of a broader cross section of the commercial real estate industry. 
We have started recruiting and developing a dedicated sales team to help support and grow the business. To support 
the  LoopNet  marketplace,  we  implemented  training  and  incentive  programs  for  our  sales  team  to  increase  sales  of 
LoopNet Ads, with a focus on brokers and property owners. We plan to expand the Ten-X sales force during 2021 and 
focus  on  increasing  the  number  of  qualified  bidders  and  the  number  of  owners  bringing  properties  to  the  site.  To 
generate brand awareness and site traffic for the LoopNet.com network and Ten-X, we plan to significantly increase 
our  investment  in  marketing  and  utilize  a  multi  media    marketing  campaign,  reinforced  with  search  engine 
optimization  efforts.  We  will  continue  to  work  to  determine  the  optimal  level  of  marketing  investment  for  each  of 
these services for future periods.

Continuing  to  invest  in  CoStar  Suite,  including  capabilities  that  allow  us  to  broaden  the  reach  of  CoStar  Suite 
internationally  by  offering  multiple  languages  and  currencies  on  the  platform.  We  plan  to  enhance  CoStar  Suite  by 
making additional investments in analytical and service capabilities focused on lenders and owners of commercial real 
estate. We also recently acquired Emporis GmbH, a Germany-based provider of international commercial real estate 
data and images that we are integrating into CoStar. In addition, we plan to invest in the technology and infrastructure 
of our other existing service offerings and the backend systems that support our offerings.

Continuing to develop, improve and market our Apartments.com service offerings that focus on creating the best and 
most comprehensive consumer rental search experience as well as continuing to advance the digital rental experience 
that allows renters to apply for leases and make rent payments, and for landlords to run tenant credit and background 
checks, all online through a single platform. We seek user feedback as we work to improve our services and continue 
to aggressively market our multifamily listing services in an effort to provide more value to consumers and, in turn, to 
attract  advertisers.  Our  Apartments.com  marketing  investment  is  focused  on  enhanced  brand  awareness  and  search 
engine marketing. As we continue to assess the success and effectiveness of our marketing campaign, we will continue 
to work to determine the optimal level and focus of our marketing investment for our services for future periods and 
may adjust our marketing spend and focus as we deem appropriate.

To  support  our  continued  expansion  and  development,  in  2020,  we  completed  a  public  equity  offering,  a  senior  notes 
offering and the refinancing of our revolving credit facility. In May 2020, we completed a public equity offering of 2.6 million 
shares of common stock for $655 per share. Net proceeds from the public equity offering were approximately $1.7 billion, after 
deducting approximately $35 million of underwriting fees, commissions and other stock issuance costs. We expect to use the 
net proceeds from the public equity offering to fund all or a portion of the costs of any strategic acquisitions we pursue in the 
future, to finance the growth of our business and/or for working capital and other general corporate purposes. General corporate 
purposes may include additions to working capital, capital expenditures, repayment of debt, investments in our subsidiaries, and 
the repurchase, redemption or retirement of securities, including our common stock.

On July 1, 2020, we issued $1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030 (the “Senior 
Notes”).  Interest  on  the  Senior  Notes  is  payable  semi-annually  in  arrears  beginning  January  15,  2021.  We  may  redeem  the 
Senior Notes in whole or in part (a) at any time prior to April 15, 2030, at a redemption price equal to 100% of the principal 
amount of the Senior Notes, plus the Applicable Premium (as calculated in accordance with the indenture governing the Senior 
Notes)  as  of,  and  any  accrued  and  unpaid  interest,  if  any,  on  the  principal  amount  of  Senior  Notes  being  redeemed  to,  but 
excluding, the redemption date, and (b) on or after April 15, 2030, at a redemption price equal to 100% of the principal amount 
of the Senior Notes, plus any accrued and unpaid interest, if any, on the principal amount of Senior Notes being redeemed to, 
but  excluding,  the  redemption  date.  We  used  a  portion  of  the  net  proceeds  from  the  issuance  of  the  Senior  Notes  to  repay 
outstanding borrowings under the 2017 Credit Agreement, and we intend to use the remaining proceeds to fund all or a portion 
of  the  costs  of  any  strategic  acquisitions  we  pursue  in  the  future,  to  finance  the  growth  of  our  business  and/or  for  working 
capital and other general corporate purposes.

On  July  1,  2020,  we  also  entered  into  a  second  amended  and  restated  credit  agreement  (the  “2020  Credit  Agreement”), 
which  amended  and  restated  in  its  entirety  our  existing  credit  agreement  (the  "2017  Credit  Agreement").  The  2020  Credit 

37

Agreement provides for a $750 million revolving credit facility with a term of five years and a letter of credit sublimit of $20 
million  from  a  syndicate  of  financial  institutions  as  lenders  and  issuing  banks.  On  July  1,  2020,  we  repaid  the  outstanding 
borrowings under our existing $750 million revolving credit facility pursuant to the 2017 Credit Agreement using the proceeds 
from  the  issuance  of  the  Senior  Notes.  Funds  drawn  down  on  the  revolving  credit  facility  pursuant  to  the  2020  Credit 
Agreement may be used for working capital and other general corporate purposes. The 2020 Credit Agreement, along with the 
proceeds  from  the  May  equity  offering,  the  July  Senior  Notes  offering  and  cash  generated  by  our  business  are  expected  to 
support our continued growth and give us flexibility to act on strategic acquisition opportunities that may arise. See Notes 11 
and  15 in this Annual Report on Form 10-K for further discussion of our recent equity and Senior Notes offerings and our 2020 
Credit Agreement.

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

For further discussion of our Company, strategy and products, see our business overview set forth in "Item 1. Business" in 

this Annual Report on Form 10-K.

Non-GAAP Financial Measures

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

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

We view EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per 
diluted  share  as  operating  performance  measures.  We  believe  that  the  most  directly  comparable  GAAP  financial  measure  to 
EBITDA,  adjusted  EBITDA  and  non-GAAP  net  income  is  net  income.  We  believe  the  most  directly  comparable  GAAP 
financial measures to non-GAAP net income per diluted share and adjusted EBITDA margin are net income per diluted share 
and net income divided by revenue, respectively. In calculating EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-
GAAP net income and non-GAAP net income per diluted share, we exclude from net income the financial items that we believe 
should  be  separately  identified  to  provide  additional  analysis  of  the  financial  components  of  the  day-to-day  operation  of  our 
business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-
GAAP financial measures as a result of these exclusions. EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP 

38

net  income  and  non-GAAP  net  income  per  diluted  share  are  not  measurements  of  financial  performance  under  GAAP  and 
should not be considered as a measure of liquidity, as an alternative to net income or as an indicator of any other measure of 
performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on EBITDA, 
adjusted  EBITDA,  adjusted  EBITDA  margin,  non-GAAP  net  income  and  non-GAAP  net  income  per  diluted  share  as  a 
substitute  for  any  GAAP  financial  measure,  including  net  income  and  net  income  per  diluted  share.  In  addition,  we  urge 
investors and potential investors in our securities to carefully review the GAAP financial information included as part of our 
Annual  Reports  on  Form  10-K  and  Quarterly  Reports  on  Form  10-Q  that  are  filed  with  the  Securities  and  Exchange 
Commission,  as  well  as  our  quarterly  earnings  releases,  and  compare  the  GAAP  financial  information  with  our  EBITDA, 
adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP net income per diluted share.

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

•

•

•

•

•

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

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

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

The  amount  of  interest  (expense)  income  and  other  (expense)  income  we  generate  and  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 (expense) income and other (expense) income 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 

39

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

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

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

The financial items that have been excluded from our net income to calculate non-GAAP net income and non-GAAP net 
income  per  diluted  share  are  amortization  of  acquired  intangible  assets  and  other  related  costs,  stock-based  compensation, 
acquisition- and integration-related costs, restructuring and related costs and settlement and impairment costs incurred outside 
our ordinary course of business. These items are discussed above with respect to the calculation of adjusted EBITDA together 
with the material limitations associated with using this non-GAAP financial measure as compared to net income. In addition to 
these exclusions from net income, we subtract an assumed provision for income taxes to calculate non-GAAP net income. In 
2020 and 2019, we assumed a 25% tax rate, which approximated our historical long-term statutory corporate tax rate, excluding 
the impact of discrete items.

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

Revenues. Revenues increased to $1.7 billion in 2020, from $1.4 billion in 2019. The $259 million increase was primarily 
attributable  to  an  $108  million,  or  22%,  increase  in  multifamily  revenue.  The  multifamily  increase  was  due  to  upsells  of 
existing customer packages to higher value advertising packages, and higher sales volume due to an increase in property listings 
as a result of recent investments in marketing. Commercial property and land revenue increased $63 million, or 31%, due to 
revenue of $32 million from the acquisition of Ten-X, and growth in our LoopNet online marketplace services of $30 million as 
a  result  of  stronger  site  traffic,  driving  sales  of  higher  value  advertisements.  CoStar  Suite  revenues  increased  $47  million, 
or  8%,  primarily  due  to  renewal  price  increases  from  prior  periods  and,  to  a  lesser  extent,  higher  sales  volume  due  to  an 
increase  in  subscribers.  Information  services  revenue  increased  $41  million,  or  47%,  primarily  due  to  $44  million  from  the 
acquisition of STR, partially offset by a decrease of $2 million in revenue for our CoStar Real Estate Manager service offerings.

Gross Profit. Gross profit increased to $1.4 billion in 2020, from $1.1 billion in 2019. The gross profit percentage was 81% 
for 2020 compared to 79% for 2019. The increase in gross profit was due to higher revenues partially impacted by an increase 
in cost of revenues of $20 million, or 7%, mostly due to the acquisitions of STR and Ten-X, which were the primary drivers of 
higher personnel costs of $12 million, and increased intangible asset amortization of $4 million, and to a lesser extent, increases 
in  bank  and  merchant  fees  of  $4  million  and  IT  equipment  and  office  supplies  of  $4  million  related  to  employees  directly 
supporting  our  customers  as  they  transitioned  to  working  from  home  during  the  COVID-19  pandemic.  These  increases  were 
partially offset by a $4 million decrease in travel and entertainment expenses for research and product support employees.

Selling and Marketing Expenses. Selling and marketing expenses increased to $536 million in 2020, from $409 million in 
2019.  The  increase  was  primarily  attributable  to  $92  million  in  additional  marketing  spend,  including  $57  million  in  search 
engine  marketing,  primarily  for  Apartments.com  and  LoopNet,  a  $40  million  increase  in  marketing  agency  fees,  and  a  $6 
million increase in other forms of marketing, led by digital, partially offset by a decrease in event spending of $11 million. In 
addition, the increase in expenses was caused by higher personnel costs of $40 million driven by the acquisitions of STR and 
Ten-X,  as  well  as,  higher  sales  commissions,  in  addition  to  $2  million  increases  in  each  of  occupancy  and  supplies.  These 
increases were partially offset by a $9 million decrease in travel and entertainment expense.

Software Development Expenses. Software development expenses increased to $163 million in 2020, from $126 million in 
2019,  and  increased  as  a  percentage  of  revenues  to  10%  in  2020,  compared  to  9%  in  2019.  The  increase  in  the  amount  of 
software development expense was primarily due to a $33 million increase in personnel costs as a result of increased headcount 
and temporary services to enhance our product offerings, including $11 million due to the acquisitions of STR and Ten-X, as 
well as a $2 million increase in occupancy costs.

General and Administrative Expenses. General and administrative expenses increased to $300 million in 2020, from $179 
million  in  2019,  and  increased  as  a  percentage  of  revenues  to  18%  in  2020  from  13%  in  2019.  The  increase  in  general  and 
administrative expenses was partially attributable to the $52 million break fee and $8 million in extension payments that we 
were  contractually  obligated  to  pay  under  the  Asset  Purchase  Agreement  with  RentPath,  which  we  terminated  in  December 
2020. In addition, there were increases in personnel costs of $27 million due to increased headcount driven by the acquisitions 
of STR and Ten-X, credit loss expense of $14 million primarily due to our expectations that the economic downturn caused by 
the COVID-19 pandemic will increase delinquent trade receivables, professional services of $14 million driven by an increase 
in other acquisition related costs, and additional software and equipment of $5 million.

Customer  Base  Amortization  Expense.  Customer  base  amortization  expense  increased  to  $62  million  in  2020,  from  $34 
million in 2019, and increased as a percentage of revenues to 4% in 2020, compared to 2% in 2019. The increase in customer 
base amortization expense was primarily due to the STR and Ten-X acquisitions.

Interest (Expense) Income. Interest (expense) income was a net expense of $17 million in 2020, as compared to net income 
of $17 million in 2019. The change from the prior year was due to an increase in interest expense of $19 million, of which, $5 
million was related to the $745 million draw on the 2017 Credit Agreement in the first quarter of 2020 and $14 million related 
to our Senior Notes issued on July 1, 2020, respectively. In addition, there was a decrease of $15 million in interest income 
caused by lower rates of return on our cash and cash equivalent balances compared to the prior year.

Other (Expense) Income. Other (expense) income was a net expense of $1 million in 2020, as compared to net income of 

$11 million in 2019. The change was primarily due to $11 million in legal settlement proceeds received in 2019.

Income Tax Expense. Income tax expense decreased to $44 million in 2020, from $76 million in 2019. The decrease was 
primarily due to lower income before income taxes for 2020, as well as an increase in excess tax benefits.  The effective tax rate 
for 2020 was 16%, compared to 19% in 2019 and lower than the statutory rates due to research and development credits as well 
as excess tax benefits.

For a comparison of our results of operations for the fiscal year ended December 31, 2019 to the year ended December 31, 
2018,  see  Item  7,  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  in  our  Annual 
Report  on  Form  10-K  for  the  year  ended  December  31,  2019,  which  was  filed  with  the  U.S.  Securities  and  Exchange 
Commission on February 26, 2020.

Comparison of Business Segment Results for Year Ended December 31, 2020 and Year Ended December 31, 2019 

We manage our business geographically in two operating segments, with the primary areas of measurement and decision-
making being North America, which includes the U.S. and Canada, and International, which primarily includes Europe, Asia-
Pacific  and  Latin  America.  Management  relies  on  an  internal  management  reporting  process  that  provides  revenue  and 
operating segment EBITDA, which is our net income before interest (expense) income and other (expense) income, loss on debt 
extinguishment,  income  taxes,  depreciation  and  amortization.  Management  believes  that  operating  segment  EBITDA  is  an 
appropriate measure for evaluating the operational performance of our operating segments. EBITDA is used by management to 
internally  measure  operating  and  management  performance  and  to  evaluate  the  performance  of  the  business.  However,  this 
measure should be considered in addition to, not as a substitute for or superior to, income from operations or other measures of 
financial performance prepared in accordance with GAAP.

Segment  Revenues.  North  America  revenues  increased  to  $1.6  billion  for  the  year  ended  December  31,  2020,  from  $1.4 
billion for the year ended December 31, 2019. The increase in North America revenues was primarily due to a $108 million 
increase  in  multifamily  revenues  driven  by  upsells  of  existing  customer  packages  to  higher  value  advertising  packages  and 
higher  sales  volume  as  a  result  of  recent  investments  in  marketing.  Commercial  property  and  land  revenues  increased  $63 
million  primarily  due  to  the  acquisition  of  Ten-X,  as  well  as  growth  in  our  LoopNet  service  offering.  Costar  Suite  revenues 
increased  $44  million  primarily  due  to  price  increases  upon  renewal  of  subscriptions  in  the  past  year,  and  to  a  lesser  extent, 
higher sales volume. Information services increased $27 million due to the acquisition of STR. International revenues increased 

44

to $57 million for the year ended December 31, 2020, from $40 million for the year ended December 31, 2019. The increase in 
International revenues was primarily due the acquisition of STR.

Segment EBITDA. North America EBITDA decreased to $411 million for the year ended December 31, 2020, from $452 
million for the year ended December 31, 2019. The decrease in North America EBITDA was due primarily to the $52 million 
break  fee  and  $8  million  in  extension  payments  that  we  were  contractually  obligated  to  pay  under  the  Asset  Purchase 
Agreement  with  RentPath,  which  we  terminated  in  December  2020.  Additionally,  increases  in  personnel,  general  and 
administrative,  and  marketing  costs  were  offset  by  an  increase  in  revenue.  International  EBITDA  increased  to  a  loss  of    $5 
million for the year ended December 31, 2020 from a loss of $7 million December 31, 2019 primarily as a result of increased 
revenue, offset by increases in personnel and general and administrative costs.

For a comparison of our business segment results of operations for the fiscal year ended December 31, 2019 to the year 
ended  December  31,  2018,  see  Item  7,  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of 
Operations in our Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the U.S. Securities 
and Exchange Commission on February 26, 2020.

Liquidity and Capital Resources

Our principal sources of liquidity are cash from operations and more recently, proceeds from our debt and equity offerings. 
Total cash, cash equivalents and restricted cash increased to approximately $3.8 billion as of December 31, 2020, compared to 
approximately  $1.1  billion  as  of  December  31,  2019.  The  increase  in  cash,  cash  equivalents  and  restricted  cash  for  the  year 
ended December 31, 2020 was primarily due to proceeds from our May 2020 equity offering, net of transaction costs, of $1.7 
billion,  as  well  as  proceeds  from  the  July  2020  issuance  of  our  Senior  Notes,  net  of  transaction  costs,  of  $983  million.  In 
addition,  cash  generated  from  operations  contributed  $486  million,  partially  offset  by  cash  paid  for  acquisitions,  net  of  cash 
acquired, of $426 million.

In May 2020, we completed a public equity offering of 2.6 million shares of common stock for $655 per share and on July 
1,  2020,  we  issued  $1.0  billion  aggregate  principal  amount  of  Senior  Notes,  entered  into  the  2020  Credit  Agreement,  which 
amended  and  restated  in  its  entirety  the  2017  Credit  Agreement,  and  repaid  in  full  the  balance  on  the  existing  $750  million 
revolving  credit  facility  under  the  2017  Credit  Agreement.  For  further  discussion  of  our  recent  equity  and  Senior  Notes 
offerings and our 2020 Credit Agreement, see “—Overview—Development, Investments and Expansion” and Notes 11 and  15 
to the accompanying Notes to the Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K 
for further discussion.

Net  cash  provided  by  operating  activities  for  the  year  ended  December  31,  2020  was  $486  million  compared  to  $458 
million  for  the  year  ended  December  31,  2019.  The  approximately  $29  million  increase  from  December  31,  2019  to 
December  31,  2020  was  primarily  due  to  changes  in  working  capital,  partially  offset  by  a  decrease  in  net  income  excluding 
certain  non-cash  expenses  such  as  depreciation  and  amortization  and  credit  loss  expense,  as  well  as  a  decrease  in  deferred 
income taxes.

Net cash used in investing activities for the year ended December 31, 2020 was $464 million compared to $484 million for 
the  year  ended  December  31,  2019.  The  $20  million  decrease  in  cash  used  in  investing  activities  was  primarily  due  to  $438 
million net cash paid for acquisitions in 2019, which included the acquisitions of STR and Off Campus Partners, compared to 
$426 million net cash paid during 2020, including the acquisitions of Homesnap, Ten-X and Emporis GmbH, as well as, the 
sale  of  our  ARS  investments  of  $10  million  in  2020.  This  was  partially  offset  by  an  increase  in  capital  expenditures  to  $48 
million in 2020 compared to $46 million during 2019.

Net cash provided by financing activities for the year ended December 31, 2020 was $2.7 billion compared to net cash used 
in  financing  activities  of  $4  million  for  the  year  ended  December  31,  2019.  This  $2.7  billion  increase  is  primarily  due  to 
proceeds from our May 2020 equity offering, net of transaction costs, of $1.7 billion, as well as, proceeds from the issuance of 
our July 1, 2020 Senior Notes, net of transaction costs, of $983 million. We expect to use the proceeds from these transactions 
to fund all or a portion of the costs of any strategic acquisitions we pursue in the future, to finance the growth of our business 
and for working capital and other general corporate purposes. The increased cash position allows for greater financial flexibility 
in  light  of  ongoing  uncertainty  in  the  global  markets  resulting  from  the  COVID-19  pandemic.  See  Notes    11  and  15  to  the 
accompanying  Notes  to  the  Consolidated  Financial  Statements  included  in  Part  IV  of  this  Annual  Report  on  Form  10-K  for 
further discussion.

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  February  11,  2020,  our  wholly  owned 
subsidiary entered into a purchase agreement to acquire all of the equity interests of reorganized RentPath, following an internal 
restructuring pursuant to a chapter 11 plan of reorganization, for $588 million in cash. The purchase agreement required us to 
deposit a $59 million termination fee into an escrow account in the event the purchase agreement is terminated prior to closing 
under  specified  circumstances.  In  December  2020,  the  sellers  gave  notice  of  termination  of  the  purchase  agreement  and  we 
commenced  an  adversary  proceeding  against  the  sellers  seeking  a  declaratory  judgment  that  RentPath  was  in  breach  of  the 
agreement and that we were not obligated to pay the termination fee. In February 2021, we and the sellers settled the adversary 
proceeding  and  agreed  that  we  would  pay  $52  million  of  the  $59  million  contractual  termination  fee.  See  Note  13  to  the 
accompanying  Notes  to  the  Consolidated  Financial  Statements  included  in  Part  IV  of  this  Annual  Report  on  Form  10-K  for 
further discussion.

On  March  27,  2020,  President  Trump  signed  into  law  the  Coronavirus  Aid,  Relief  and  Economic  Security  Act  (the 
"CARES  Act").  The  CARES  Act,  among  other  things,  includes  provisions  relating  to  the  deferral  of  taxes,  valuation 
allowances,  and  balance  sheet  classifications,  as  well  as  provisions  relating  to  refundable  payroll  tax  credits,  deferral  of 
employer social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications 
to  the  net  interest  deduction  limitations  and  technical  corrections  to  tax  depreciation  methods  for  qualified  improvement 
property. As permitted under the CARES Act, we deferred payroll taxes due in 2020 to 2021 and 2022.

As of the filing date of this Annual Report on Form 10-K, we believe that our available cash combined with positive cash 
flow provided by operating activities should be sufficient for us to maintain and fund our operations for at least the next twelve 
months.  Our  ability  to  maintain  adequate  capital  for  our  operations  in  the  future  depends  upon  numerous  rapidly  evolving 
factors, many of which we cannot accurately predict or assess, including, among others, the length and severity of the economic 
downturn  associated  with  the  COVID-19  pandemic,  related  disruption  of  the  international  and  national  economy  and  credit 
markets;  actions  taken  by  governments,  businesses  and  individuals  in  response  to  the  pandemic  such  as  office  and  other 
workplace closures, worker absenteeism, quarantines, mass-transit disruptions or other travel or health-related restrictions; how 
quickly economies, including the commercial real estate industry in particular, recover after the pandemic subsidies; sales of 
our services; and collection of accounts receivables. We plan to continue to monitor and evaluate the financial impact of the 
COVID-19 pandemic as it evolves.

Contractual  Obligations.  The  following  table  summarizes  our  principal  contractual  obligations  at  December  31,  2020, 
excluding the RentPath termination fee and the effect such obligations are expected to have on our liquidity and cash flows in 
future periods (in thousands):

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
Income taxes
Revenue recognition
Business combinations

With respect to our accounting policy for long-lived assets, intangible assets and goodwill, we further supplement in Note 2 

of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K with the following:

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

•
•
•
•

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

When  we  determine  that  the  carrying  value  of  long-lived  and  identifiable  intangible  assets  may  not  be  recovered  based 

upon the existence of one or more of the above indicators, we test for impairment.

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

Goodwill represents the 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.  We  may  first  assess  qualitative  factors  to  evaluate 
whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or elect to bypass such 
assessment. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, 
or we elect to bypass such assessment, we then determine 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, 2020, we assessed the relevant qualitative factors 
for our North America reporting unit and concluded that it was not more likely than not that the fair value of this reporting unit 
was less than its respective carrying amounts. We elected to bypass performing the qualitative screen and performed the first 

49

step  quantitative  analysis  of  the  goodwill  impairment  test  for  our  International  reporting  unit  in  the  current  year,  which 
indicated that the fair value of this unit exceeded its carrying value.

There  have  been  no  events  or  changes  in  circumstances  as  a  result  of  our  qualitative  impairment  analysis  on  October  1, 

2020, that would indicate that the carrying value of each reporting unit may not be recoverable.

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

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

We  provide  information,  analytics  and  online  marketplace  services  to  commercial  real  estate  and  related  business 
communities  within  the  regions  where  we  operate  which  primarily  include,  North  America,  Europe,  Asia-Pacific  and  Latin 
America.  The  functional  currency  for  a  majority  of  our  operations  is  the  local  currency,  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 years ended December 31, 2020 and December 31, 2019, revenues denominated in foreign currencies 
were  approximately  5%  and  4%,  respectively,  of  total  revenue.  For  the  years  ended  December  31,  2020  and  December  31, 
2019,  our  revenues  would  have  decreased  by  approximately  $8  million  and  $6  million  if  the  U.S.  dollar  exchange  rate  used 
strengthened by 10%. For the years ended December 31, 2020 and December 31, 2019, our revenues would have increased by 
approximately $8 million and $6 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,  2020,  accumulated  other  comprehensive  loss 
included a loss from foreign currency translation adjustments of approximately $0.9 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, 2020. As of December 31, 2020, we had $3.8 billion of cash, cash equivalents 
and restricted cash. If there is an increase or decrease in interest rates, there will be a corresponding increase or decrease in the 
amount  of  interest  earned  on  our  cash  and  cash  equivalents.  We  currently  diversify  our  cash  and  cash  equivalents  holdings 
amongst multiple financial institutions.

We are subject to interest rate market risk in connection with our new revolving credit facility. On July 1, 2020, we entered 
into the 2020 Credit Agreement, which provides for variable rate borrowings of up to $750 million. On July 1, 2020, we issued 
$1.0 billion aggregate principal amount of 2.800% Senior Notes due July 15, 2030. Changes in interest rates would not have a 
material impact to our current interest and debt financing expense, as all our borrowings except for our credit facility are fixed 
rate, and our credit facility is currently undrawn as of December 31, 2020. See Note 11 of the Notes to Consolidated Financial 
Statements included in this Annual Report on Form 10-K regarding our 2020 Credit Agreement.

We had approximately $2.7 billion of goodwill and intangible assets as of December 31, 2020. As of December 31, 2020, 
we believe our intangible assets will be 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.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A.  Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our 
reports  filed  or  submitted  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported,  within  the  time  periods 
specified  in  the  Securities  and  Exchange  Commission’s  rules  and  forms,  and  that  such  information  is  accumulated  and 
communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow 
for  timely  decisions  regarding  required  disclosure.  In  designing  and  evaluating  the  disclosure  controls  and  procedures, 
management  recognized  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can  provide  only 
reasonable  assurance  of  achieving  the  desired  control  objectives,  and  management  is  required  to  apply  its  judgment  in 
evaluating the cost-benefit relationship of possible controls and procedures.

We  carried  out  an  evaluation,  under  the  supervision  and  with  the  participation  of  our  management,  including  our  Chief 
Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls 
and procedures as of the end of the fiscal year. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer 
concluded that our disclosure controls and procedures were effective and were operating at a reasonable assurance level as of 
December 31, 2020.

We continue to implement a financial system that is designed to improve the efficiency and effectiveness of our operational 
and  financial  accounting  processes.  This  implementation  is  expected  to  continue  beyond  2021.  Consistent  with  any  process 
change that we implement, the design of the internal controls has and will continue to be evaluated for effectiveness as part of 
our overall assessment of the effectiveness of our disclosure controls and procedures. We expect that the implementation of this 
system will improve our internal controls over financial reporting.

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

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 

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.

limitations, 

inherent 

its 

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, 

51

 
2020 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, 2020.

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  December  22,  2020  and  June  24,  2020,  we  completed  the  acquisitions  of  Homesnap  and  Ten-X,  respectively.  As 
permitted by the Securities and Exchange Commission, we have elected to exclude the internal controls of these acquisitions 
that  have  not  been  integrated  into  our  existing  processes  and  controls  from  our  assessment  of  the  effectiveness  of  internal 
control over financial reporting as of December 31, 2020. The excluded aggregate financial position of Homesnap and Ten-X 
collectively represented less than 1% of our total assets as of December 31, 2020, and less than 2% of our revenues and total 
operating costs for the year then ended. We will include the internal controls of Homesnap and Ten-X in our assessment of the 
effectiveness of our internal control over financial reporting as of December 31, 2021.

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, 2020 
and 2019, the related consolidated statements of operations, comprehensive income, change in stockholders’ equity, and cash 
flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2020,  and  the  related  notes  and  the  financial  statement 
schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). In our opinion, 
the  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  at 
December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2020, in conformity with U.S. generally accepted accounting principles.

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

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.

Description 
of the Matter

Valuation of Acquired Intangible Assets
As  described  in  Note  5  to  the  consolidated  financial  statements,  during  the  year  ended 
December 31, 2020, the Company completed the acquisition of Ten-X Holding Company, Inc. 
("Ten-X") for $187.7 million in cash. The Company’s accounting for the acquisition included 
determining the fair value of the acquired intangible assets, including customer relationships of 
$46 million.

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

How We 
Addressed 
the Matter in 
Our Audit

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

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

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,  2020,  based  on  criteria 
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission  (2013  framework)  (the  COSO  criteria).  In  our  opinion,  CoStar  Group,  Inc.  (the  Company)  maintained,  in  all 
material respects, effective internal control over financial reporting as of December 31, 2020, 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 Ten-X and Homesnap, which are included in the 2020 consolidated financial statements of CoStar Group, Inc., and 
collectively  constituted  less  than  1%  of  total  assets  as  of  December  31,  2020  and  less  than  2%  of  total  revenues  and  total 
operating costs for the year then ended. Our audit of internal control over financial reporting of CoStar Group, Inc. also did not 
include an evaluation of the internal control over financial reporting of Ten-X and Homesnap.

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

Basis for Opinion

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

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

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

Definition and Limitations of Internal Control Over Financial Reporting

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

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

ORGANIZATION 

CoStar Group, Inc. (the “Company” or “CoStar”) provides information, analytics and online marketplace services to the 
commercial  real  estate  and  related  business  community  through  its  comprehensive,  proprietary  database  of  commercial  real 
estate information. The Company provides online marketplaces for commercial real estate, apartment rentals, lands for-sale and 
businesses  for-sale,  and  its  services  are  typically  distributed  to  its  clients  under  subscription-based  license  agreements  that 
renew  automatically,  a  majority  of  which  have  a  term  of  at  least  one  year.  The  Company  operates  within  two  operating 
segments, North America, which includes the United States (“U.S.”) and Canada, and International, which primarily includes 
Europe, Asia-Pacific and Latin America. 

On  October  22,  2019,  the  Company  acquired  STR,  Inc.  and  STR  Global,  Ltd.  (together  with  STR,  Inc.,  referred  to  as 
"STR"). STR provides benchmarking and analytics for the hospitality industry. On June 24, 2020, the Company acquired Ten-X 
Holding Company, Inc. and its subsidiaries ("Ten-X"), which operate an online auction platform for commercial real estate. On 
October 26, 2020, the Company acquired Emporis GmbH, a Germany-based provider of international commercial real estate 
data  and  images.  On  December  22,  2020,  the  Company  acquired  Homesnap,  Inc  (“Homesnap”),  which  operates  an  online 
mobile software platform for residential real estate agents and brokers. See Notes 5 and 9 to the accompanying Notes to the 
Consolidated Financial Statements for further discussion of these acquisitions.

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 long-lived and intangible assets, and 
goodwill;  income  taxes,  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 the 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. The Company’s subscription-based license agreements typically renew automatically, and a majority have a 
term of at least one year.

The  Company  also  provides  (i)  market  research,  portfolio  and  debt  analysis,  management  and  reporting  capabilities,  (ii) 
real estate and lease management solutions, including lease administration and abstraction services, to commercial customers, 

F-11

COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

real  estate  investors,  and  lenders,  (iii)  benchmarking  and  analytics  for  the  hospitality  industry  through  STR,  (iv)  an  online 
auction platform for commercial real estate through Ten-X and its subsidiaries, which were acquired in June 2020, and (v) an 
online  and  mobile  software  platform  that  provides  applications  to  optimize  residential  real  estate  agent  workflow  through 
Homesnap, which was acquired in December 2020. See Note 5 for details of the acquisitions.

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

The  Company  recognizes  revenues  upon  the  satisfaction  of  its  performance  obligation(s)  (upon  transfer  of  control  of 
promised services to its customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange 
for  those  services.  Revenues  from  subscription-based  services  are  recognized  on  a  straight-line  basis  over  the  term  of  the 
agreement. 

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.

Deferred revenue results from amounts billed in advance to customers or cash received from customers in advance of the 

Company's fulfillment of its performance obligation(s) and is recognized as those obligations are satisfied.

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

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

See Note 3 for further discussion of the Company's revenue recognition.

Cost of Revenues

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

Foreign Currency Translation

The Company’s reporting currency is the U.S. dollar. The functional currency for the majority of its operations is the local 
currency, with the exception of certain international locations of STR for which the functional currency is the British Pound. 
Assets and liabilities denominated in a foreign currency are translated into U.S. dollars using the exchange rates in effect as of 
the  balance  sheet  date.  Gains  and  losses  resulting  from  translation  are  included  in  accumulated  other  comprehensive  loss. 
Currency  gains  and  losses  on  the  translation  of  intercompany  loans  made  to  foreign  subsidiaries  that  are  of  a  long-term 
investment  nature  are  also  included  in  accumulated  other  comprehensive  loss.  Gains  and  losses  resulting  from  transactions 
denominated  in  a  currency  other  than  the  functional  currency  of  the  entity  are  included  in  other  (expense)  income  in  the 
consolidated statements of operations using the average exchange rates in effect during the period. The Company recognized 
net foreign currency losses of $0.2 million, $0.6 million and $0.1 million for the years ended December 31, 2020, 2019 and 
2018, respectively, which are included in other (expense) income on the consolidated statement of operations.

During the year ended December 31, 2020, the Company sold its long-term variable debt instruments with an auction reset 
feature, referred to as auction rate securities ("ARS") and reclassified out of accumulated other comprehensive loss a realized 
loss of $0.5 million to earnings which is included in other (expense) income in the consolidated statement of operations. There 
were no amounts reclassified out of accumulated other comprehensive loss to the consolidated statements of operations for the 
years ended December 31, 2019 and 2018.

Advertising Costs

The  Company  expenses  advertising  costs  as  incurred.  Advertising  costs  include  e-commerce,  television,  radio,  print  and 
other media advertising. Advertising costs were approximately $270 million, $168 million and $125 million for the years ended 
December 31, 2020, 2019 and 2018, respectively.

Income Taxes

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

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

cost method.  

See Note 12 for additional information regarding income taxes.

Net Income Per Share

Net income per share is computed by dividing net income by the weighted-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 outstanding stock options, and unvested stock-based awards 
which include restricted stock awards that vest over a specific service period, restricted stock awards with a performance and 
market conditions, restricted stock units and awards of 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  stock-based  awards.  Shares  underlying  unvested  restricted  stock  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 per share considers the impact of potentially dilutive securities except 
when  the  inclusion  of  the  potentially  dilutive  securities  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

Equity  instruments  issued  in  exchange  for  services  performed  by  officers,  employees,  and  directors  of  the  Company  are 
accounted  for  using  a  fair-value  based  method  and  the  fair  value  of  such  equity  instruments  is  recognized  as  expense  in  the 
consolidated statements of operations.

F-13

 
 
 
 
COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For stock-based awards that vest over a specific service period, compensation expense is measured based on the fair value 
of  the  awards  at  the  grant  date,  and  is  recognized  on  a  straight-line  basis  over  the  vesting  period  of  the  awards,  net  of  an 
estimated  forfeiture  rate.  For  equity  instruments  that  vest  based  on  achievement  of  a  performance  condition,  stock-based 
compensation  expense  is  recognized  based  on  the  expected  achievement  of  the  related  performance  conditions  at  the  end  of 
each  reporting  period  over  the  vesting  period  of  the  awards.  If  the  Company's  initial  estimates  of  the  achievement  of  the 
performance conditions change, the related stock-based compensation expense and timing 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 awards with both a performance 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 for stock options, restricted stock awards and restricted stock units issued under equity 
incentive plans, stock purchases under the Employee Stock Purchase Plan, Deferred Stock Units ("DSUs") and Matching RSUs 
awarded under the MSPP included in the Company’s results of operations were as follows (in thousands):

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. As of December 31, 2019, the Company's investments consisted of 
long-term  variable  rate  debt  instruments  with  an  auction  reset  feature,  referred  to  as  auction  rate  securities.  The  Company's 
auction rate security investments were classified as available-for-sale and carried at fair value, with any changes in unrealized 
holding  gains  and  losses,  net  of  the  related  tax  effect  excluded  from  earnings  and  reported  as  a  separate  component  of 
accumulated other comprehensive loss in stockholders’ equity until realized. A decline in market value of any investment below 
cost  that  is  deemed  to  be  other-than-temporary  results  in  a  reduction  in  carrying  amount  to  fair  value.  The  impairment  is 
charged  to  earnings  and  a  new  cost  basis  for  the  security  is  established.  Dividend  and  interest  income  are  recognized  when 
earned.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Concentration of Credit Risk and Financial Instruments

The  Company’s  customer  base  creates  a  lack  of  dependence  on  any  individual  customer  that  mitigates  the  risk  of 
nonpayment  of  the  Company’s  accounts  receivable.  No  single  customer  accounted  for  more  than  5%  of  the  Company’s 
revenues  for  each  of  the  years  ended  December  31,  2020,  2019,  and  2018.  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  diversifying  cash  holdings  across  AAA 
rated  Government  and  Treasury  Money  Market  Funds  and  multiple  high  quality  financial  institutions,  and  by  periodically 
evaluating the credit quality of the primary financial institutions holding such deposits. The carrying value of cash approximates 
fair value. Historically, the Company has not experienced any losses due to such cash concentrations. 

Allowance for Credit Losses

On  January  1,  2020,  the  Company  adopted  Accounting  Standards  Updates  ("ASU")  2016-13,  Financial  Instruments  - 
Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments; ASU 2018-19, Codification Improvements 
to  Topic  326,  Financial  Instruments  -  Credit  Losses;  ASU  2019-04,  Codification  Improvements  to  Financial  Instruments  - 
Credit Losses (Topic 326); ASU 2019-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on 
Financial Instrument; ASU 2019-11, Codification Improvements to Financial Instruments - Credit Losses (Topic 326) and ASU 
2020-02,  Financial  Instruments-Credit  Losses  (Topic  326)  and  Leases  (Topic  842),  later  codified  as  Accounting  Standards 
Codification ("ASC") 326 ("ASC 326"), using the modified retrospective transition approach. Refer to the Company’s Annual 
Report on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission on February 
26, 2020, for further details of the Company’s policy prior to the adoption of ASC 326.

As of January 1, 2020, the Company maintained an allowance for credit losses to cover its current expected credit losses 
("CECL") on its trade receivables and contract assets arising from the failure of customers to make contractual payments. The 
Company  estimates  credit  losses  expected  over  the  life  of  its  trade  receivables  and  contract  assets  based  on  historical 
information  combined  with  current  conditions  that  may  affect  a  customer’s  ability  to  pay  and  reasonable  and  supportable 
forecasts. While the Company uses various credit quality metrics, it primarily monitors collectability by reviewing the duration 
of collection pursuits on its delinquent trade receivables. Based on the Company’s experience, the customer's delinquency status 
is the strongest indicator of the credit quality of the underlying trade receivables, which is analyzed monthly. In most instances, 
the Company’s policy is to write-off trade receivables when they are deemed uncollectible. A majority of the Company's trade 
receivables are less than 365 days outstanding.

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

•

•

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

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

Leases

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

In determining the amount of lease payments used in measuring ROU assets and lease liabilities, the Company has elected 
the  practical  expedient  not  to  separate  non-lease  components  from  lease  components  for  all  classes  of  underlying  assets. 
Consideration  deemed  part  of  the  lease  payments  used  to  measure  ROU  assets  and  lease  liabilities  generally  includes  fixed 
payments and variable payments based on either an index or a rate, offset by lease incentives. Upon commencement, the initial 
ROU  asset  also  includes  any  lease  prepayments.  ROU  assets  and  liabilities  are  recognized  at  the  lease  commencement  date 
based on the present value of lease payments over the lease term. The rates implicit within the Company's leases are generally 
not  determinable.  Therefore,  the  Company's  incremental  borrowing  rate  is  used  to  determine  the  present  value  of  lease 
payments.  The  determination  of  the  Company’s  incremental  borrowing  rate  requires  judgment  and  is  determined  at  lease 
commencement,  or  as  of  January  1,  2019  for  operating  leases  in  existence  upon  adoption  of  ASC  842.  The  incremental 
borrowing rate is subsequently reassessed upon a modification to the lease arrangement.

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

term.

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

Property and Equipment, Net

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

Buildings 
Land
Aircrafts
Furniture and office equipment
Vehicles
Computer hardware and software

Leasehold improvements

Twenty to thirty-nine years 
Indefinite
Ten to twenty years
Five to ten years
Five years
Three to five years

Shorter of lease terms or useful life

Qualifying  internal-use  software  costs  incurred  during  the  application  development  stage,  which  consist  primarily  of 
internal product development costs, outside services and purchased software license costs are capitalized and amortized over the 
estimated useful life of the asset. All other costs are expensed as incurred.

Long-Lived Assets, Intangible Assets and Goodwill

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

F-16

COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Acquired technology and data, customer base assets, trade names and other intangible assets are related to the Company’s 
acquisitions (see Notes 5, 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 the net identifiable assets acquired. Goodwill is not 
amortized,  but  instead  is  assigned  to  each  of  the  Company's  reporting  units  and  tested  for  impairment  at  least  annually  on 
October 1, or more frequently if an event or other circumstance indicates that the fair value of a reporting unit may be below its 
carrying amount. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying 
value, 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  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. 

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. The 
Company made a policy election to classify deferred issuance costs on the revolving credit facility as a long-term asset on its 
consolidated  balance  sheets.  Upon  a  refinancing  or  amendment,  previously  capitalized  debt  issuance  costs  are  expensed  and 
included  in  loss  on  extinguishment  of  debt  if  the  Company  determines  that  there  has  been  a  substantial  modification  of  the 
related debt. If the Company determines that there has not been a substantial modification of the related debt, any previously 
capitalized debt issuance costs are amortized as interest expense over the term of the new debt instrument.

See Note 11 for additional information regarding the Company's 2020 Credit Agreement and Senior Notes issuance.

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. The Company applies significant assumptions, estimates, and judgments in determining the 
fair  value  of  assets  acquired  and  liabilities  assumed  on  the  acquisition  date,  especially  with  respect  to  intangible  assets  and 
contingent liabilities. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected 
cash  flows  from  acquired  customer  bases,  acquired  technology  and  acquired  trade  names,  useful  lives,  royalty  rates  and 
discount rates. Any adjustments to provisional amounts that are identified during the measurement period are recorded in the 
reporting  period  in  which  the  adjustment  amounts  are  determined.  Upon  the  conclusion  of  the  measurement  period,  any 
subsequent adjustments are recorded to earnings.

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

If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by 
the end of the measurement period, which is generally the case given the nature of such matters, the Company will recognize an 
asset or a liability for such pre-acquisition contingency if: (i) it is probable that an asset existed or a liability had been assumed 
at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement 
period, changes in the Company's estimates of such contingencies will affect earnings and could have a material effect on its 
results of operations and financial position.

COSTAR GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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, 2020, the Company adopted ASU 2019-12, Simplifying the Accounting for Income Taxes, on a prospective 
basis. The amounts related to the reclassification of franchise taxes from income from operations to income tax expense for the 
year ended December 31, 2020 did not have a material impact on the Company's consolidated financial statements and related 
disclosures.

On  January  1,  2020,  the  Company  adopted  ASU  2018-15,  Intangibles  -  Goodwill  and  Other  -  Internal-Use  Software 
(Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a 
Service Contract, on a prospective basis. ASU 2018-15 requires a customer in a cloud computing arrangement that is a service 
contract  to  follow  the  internal-use  software  guidance  in  ASC  350-40  to  determine  which  implementation  costs  to  defer  and 
recognize  as  an  asset.  The  adoption  did  not  have  a  material  impact  on  the  Company's  consolidated  financial  statements  and 
related disclosures.

On January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement 
of  Credit  Losses  on  Financial  Instruments,  using  the  modified  retrospective  method.  This  accounting  standard  replaced  the 
prior  incurred  loss  accounting  model  with  a  current  expected  credit  loss  approach.  As  of  January  1,  2020,  no  cumulative 
transition  adjustment  was  recorded  to  the  beginning  balance  of  retained  earnings,  as  the  adoption  did  not  result  in  a  higher 
allowance for credit losses under the CECL impairment model. The adoption did not have a material impact on the Company's 
consolidated financial statements and related disclosures.

Recent Accounting Pronouncements Not Yet Adopted

On  January  16,  2020,  the  Financial  Accounting  Standards  Board  issued  ASU  2020-01,  Investments-Equity  Securities 
(Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The new 
standard  clarifies  the  interaction  of  accounting  for  the  transition  into  and  out  of  the  equity  method.  The  new  standard  also 
clarifies  the  accounting  for  measuring  certain  purchased  options  and  forward  contracts  to  acquire  investments.  The  ASU  is 
effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption 
is permitted, including adoption in an interim period. The Company will adopt this guidance in the first quarter of 2021 and 
does not expect it to have a material impact on its consolidated financial statements.

On  March  12,  2020,  the  Financial  Accounting  Standards  Board  issued  ASU  2020-04,  Reference  Rate  Reform  (“ASC 
848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASC 848 contains optional expedients and 
exceptions  for  applying  GAAP  to  debt,  contracts,  hedging  relationships,  and  other  transactions  affected  by  reference  rate 
reform. The provisions of ASC 848 must be applied to all contracts that are accounted for under a Topic, Subtopic or Industry 
Subtopic  for  all  transactions  other  than  derivatives,  which  may  be  applied  at  a  hedging  relationship  level.  This  guidance  is 
effective for fiscal years beginning after January 1, 2021, including interim periods within those fiscal years. The Company's 
2020 Credit Agreement provides for a $750 million revolving credit facility and a letter of credit sublimit of $20 million, with 
interest  rates  benchmarked  to  LIBOR.  As  of  December  31,  2020,  no  amounts  were  issued  or  drawn  under  this  facility.  The 
Company's  Senior  Notes  have  a  fixed  interest  rate  and  will  not  be  impacted  by  this  standard.  The  Company  is  currently 
evaluating the impact this guidance will have on its consolidated financial statements and related disclosures.

Sub  Corp.,  a  Delaware  corporation  and  wholly-owned  subsidiary  of  CRI  (“Merger  Sub”),  and  Homesnap,  Inc.,  a  Delaware 
corporation  ("Homesnap"),  Merger  Sub  was  merged  with  and  into  Homesnap  (the  “Homesnap  Merger”),  with  Homesnap 
surviving the merger as a wholly-owned subsidiary of CRI. In connection with the Homesnap Merger, the Company acquired 
all of the issued and outstanding equity interests in Homesnap for a purchase price of $250 million in cash. Homesnap is an 
industry-leading online and mobile software platform that provides user-friendly applications to optimize residential real estate 
agent workflow and reinforce the agent-client relationship. Homesnap has relationships, data, software, and tools for residential 
real estate professionals that are complementary to CoStar’s existing offerings. The acquisition of Homesnap enables CoStar to

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 Homesnap 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 Homesnap's operations; and (ii) any

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 Ten-X 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  Ten-X's  operations;  and  (ii)  any 
intangible assets that do not qualify for separate recognition, such as the assembled workforce. The $136 million of goodwill 
recorded as part of the acquisition is associated with the Company's North America operating segment. Goodwill recorded in 
connection  with  this  acquisition  is  not  amortized,  but  is  subject  to  an  annual  impairment  test.  Goodwill  recognized  is  not 
deductible for income tax purposes.

As of December 31, 2020, transaction costs associated with the Ten-X acquisition were not material. The Company paid 
$3  million  in  incentive  compensation  to  Ten-X  employees;  this  payment  was  negotiated  as  part  of  the  acquisition  and  the 
expense was recognized in the post-combination period.

STR, Inc. and STR Global Ltd.

      On October 22, 2019, the Company acquired all of the issued and outstanding equity interests of STR for a purchase price 
of $436 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):

      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 customer base assets incorporated significant assumptions that had a material impact on the 
estimated  fair  value,  such  as  discount  rates,  projected  revenue  growth  rates,  customer  attrition  rates  and  projected  profit 
margins. The following table summarizes the fair values (in thousands) of the identifiable intangible assets included in each of

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 $262 million of goodwill recorded as 
part  of  the  acquisition,  $159  million  and  $103  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 on the acquisition date. In the 
event  some  or  all  of  those  employees  were  not  entitled  to  their  retention  bonus,  the  funds  were  to  be  remitted  to  the  seller. 
During 2020, the retention bonus was paid to active and eligible employees and funds otherwise payable to any employees who 
were not entitled to their retention bonus were remitted to the seller. 

Off Campus Partners, LLC 

       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.  During 2020, the Company paid the remaining purchase price in full. 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. Measurement period adjustments recognized in 2019 were not material.

Pro Forma Financial Information (unaudited)

The  unaudited  pro  forma  financial  information  presented  below  summarizes  the  combined  results  of  operations  for  the 
Company, the ForRent acquisition which closed during 2018, and the STR, Ten-X and Homesnap acquisitions, in each case, as 
though  the  companies  were  combined  as  of  January  1,  2017,  2018,  2019  and  2019,  respectively.  The  impact  of  the  October 
2020  Emporis  GmbH  and  OCP  acquisitions  on  the  pro  forma  financial  information  was  not  material  and  therefore  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 had taken place on January 1, 2017, 2018,  2019  and 2019, respectively.

The  unaudited  pro  forma  financial  information  for  the  years  ended  December  31,  2020,  2019  and  2018  combine  the 
historical results of the Company for the years ended December 31, 2020, 2019 and 2018, the historical results of the Company,

INVESTMENTS AND FAIR VALUE MEASUREMENTS 

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

As  of  December  31,  2020,  the  Company's  financial  assets  comprise  Level  1  cash  equivalents  with  original  maturities  of 
three  months  or  less  in  the  amount  of  $3,394  million.  As  of  December  31,  2020,  the  Company  had  no  Level  2  or  Level  3 
financial assets measured at fair value.

During  the  year  ended  December  31,  2020,  the  Company  sold  its  ARS  investments  for  $10.3  million  and  recognized  a 
realized  loss  of  $0.5  million  for  the  year  ended  December  31,  2020  which  was  included  in  other  (expense)  income  on  the 
Company's consolidated statements of operations.

The  following  table  represents  the  Company's  investments  in  marketable  securities  and  fair  value  measurements  by

The Company’s Level 3 assets consisted of ARS; whose underlying assets were primarily student loan securities supported 
by  guarantees  from  the  Federal  Family  Education  Loan  Program  of  the  U.S.  Department  of  Education.  As  of  December  31, 
2019, these investments were in an unrealized loss position for a period of twelve months or greater. The unrealized losses 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 were 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. The Company had no realized gains or losses on its 
investments during the year ended December 31, 2019.

In  addition  to  the  financial  instruments  listed  above,  the  Company  holds  other  financial  instruments,  including  cash 
equivalents,  cash  deposits,  accounts  receivable,  accounts  payable,  accrued  expenses  and  senior  notes.  The  carrying  value  for 
such  financial  instruments,  other  than  the  senior  notes,  each  approximated  their  fair  values  as  of  December  31,  2020  and 
December 31, 2019. The estimated fair value of the Company's outstanding senior notes using quoted prices from the over-the-
counter markets, considered Level 2 inputs, was $1.04 billion as of December 31, 2020.

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

In  connection  with  the  issuance  of  the  Senior  Notes,  the  Company  incurred  approximately  $13  million  in  debt  issuance 

costs.

Revolving Credit Facility

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

Subject  to  certain  conditions,  on  no  more  than  five  occasions,  the  Company  may  request  increases  in  the  amount  of 
revolving commitments and/or the establishment of term commitments under the 2020 Credit Agreement. Borrowings under the 
2020 Credit Agreement will bear interest at a floating rate which can be, at the Company’s option, either (a) an alternate base 
rate plus an applicable rate ranging from 0.50% to 1.25% or (b) a LIBOR or EURIBOR (with a floor of 0.0%) for the specified 
interest period plus an applicable rate ranging from 1.50% to 2.25%, in each case depending on the Company's Total Leverage 
Ratio (as defined in the 2020 Credit Agreement). As LIBOR may not always be available to the Company as a base interest rate 
for borrowings under the credit facility, the 2020 Credit Agreement allows for an amendment to replace LIBOR with one or 
more Secured Overnight Financing Rate (“SOFR”) based rates or another alternative benchmark rate. Funds drawn down on the 
revolving credit facility pursuant to the 2020 Credit Agreement may be used for working capital and other general corporate 
purposes of the Company and its restricted subsidiaries. The obligations under the 2020 Credit Agreement are guaranteed by 
each of the Company’s current and future direct or indirect wholly owned restricted domestic subsidiaries, other than certain 
excluded subsidiaries, in each case subject to certain exceptions, pursuant to guarantee agreements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The 2020 Credit Agreement includes covenants, including ones that, subject to certain exceptions, restrict the ability of the 
Company  and  its  subsidiaries  to  (i)  merge  and  consolidate  with  other  companies,  (ii)  incur  indebtedness,  (iii)  grant  liens  or 
security interests on assets, (iv) make investments, acquisitions, loans or advances, (v) pay dividends and (vi) sell or otherwise 
transfer assets. During any period of time that the Company has obtained and maintained a corporate investment grade rating 
from at least two designated rating agencies and no Event of Default is continuing, the Company will not be subject to certain 
of these covenants such as restrictions on the ability to incur indebtedness (such period, a “Covenant Suspension Period”). As 
of  December  31,  2020,  the  Company  is  in  a  Covenant  Suspension  Period.  The  2020  Credit  Agreement  also  requires  the 
Company  to  maintain  a  Total  Leverage  Ratio  (as  defined  in  the  2020  Credit  Agreement)  not  exceeding  4.50  to  1.00.  The 
Company was in compliance with the covenants in the 2020 Credit Agreement as of December 31, 2020.

In connection with the 2020 Credit Agreement, the Company incurred approximately $3.6 million in debt issuance costs. 

As of December 31, 2020, the Company had not drawn any amounts under this facility.

The Company had an irrevocable standby letter of credit outstanding totaling $0.2 million as of December 31, 2020 and 
December 31, 2019, which is required to secure its San Francisco office lease. The letter of credit was established in 2014 and 
automatically renews annually through January 31, 2025.

For  the  years  ended  December  31,  2020,  2019  and  2018  the  Company  recognized  interest  expense  as  follows  (in

For the years ended December 31, 2020 and 2019, the Company has not recognized deferred tax liabilities for temporary 
differences related to investments in foreign subsidiaries that were deemed permanent reinvested. Determination of the amount 
of unrecognized deferred income tax liabilities on these earnings is not practicable because such liability, if any, depends on 
certain  circumstances  existing  if  and  when  remittance  occurs.  A  deferred  tax  liability  will  be  recognized  if  and  when  the 
Company no longer plans to permanently reinvest these undistributed earnings.

As of December 31, 2020 and 2019, a valuation allowance has been established for certain deferred tax assets due to the 
uncertainty of realization. The valuation allowance as of December 31, 2020 includes an allowance for acquired net operating

losses  and  foreign  deferred  tax  assets.  The  valuation  allowance  as  of  December  31,  2019  includes  an  allowance  for  foreign 
deferred tax assets and state net operating losses and tax credits. 

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 
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. The Company has established a valuation allowance for 
certain  acquired  net  operating  losses  where  Section  382  limitations  will  impact  the  ability  of  the  Company  to  utilize  the  net 
operating losses before they expire.

The  Company’s  change  in  valuation  allowance  was  a  decrease  of  approximately  $2.4  million  for  the  year  ended 
December 31, 2020 and a decrease of approximately $0.7 million for the year ended December 31, 2019. The decrease for the 
year  ended  December  31,  2020  is  primarily  due  to  the  removal  of  the  valuation  allowance  for  the  D.C.  qualified  high 
technology company tax credits which expired in 2020, partially offset by an increase in the valuation allowance for acquired 
net  operating  losses.  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  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. 

The Company had U.S. income before income taxes of approximately $291 million, $403 million and $294 million for the 
years  ended  December  31,  2020,  2019  and  2018,  respectively.  The  Company  had  foreign  losses  before  income  taxes  of 
approximately $20 million, $12 million, and $10 million for the years ended December 31, 2020, 2019 and 2018, respectively. 

The Company’s provision for income taxes resulted in effective tax rates that varied from the statutory federal income tax

Certain  of  the  Company’s  U.K.  subsidiaries  with  foreign  losses  are  disregarded  entities  for  U.S.  income  tax  purposes. 
Accordingly,  the  losses  from  these  disregarded  entities  are  included  in  the  Company’s  consolidated  federal  income  tax 
provision  at  the  statutory  rate.  Federal  income  taxes  attributable  to  income  from  these  disregarded  entities  are  reduced  by 
foreign taxes paid by those disregarded entities.

The  Company  has  net  operating  loss  carryforwards  for  international  income  tax  purposes  of  approximately  $48  million, 
which do not expire. The Company has federal net operating loss carryforwards of approximately $111 million that begin to 
expire in 2029, state net operating loss carryforwards with a tax value of approximately $6 million that begin to expire in 2029 
and state income tax credit carryforwards with a tax value of approximately $6 million primarily relating to state research and 
development credits that do not expire. The Company realized a cash benefit relating to the use of its tax loss carryforwards of 
approximately $5 million, $6 million and $6 million in December 31, 2020, 2019 and 2018, respectively.

Approximately  $29  million  and  $25  million  of  the  unrecognized  tax  benefits  as  of  December  31,  2020  and  2019, 
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 $5 million for the year ended December 31, 2020 is primarily attributable to research credits. The 
decrease for expiration of the statute of limitation of $1 million for the year ended December 31, 2020 is primarily attributable 
to the reserve for the D.C. qualified high technology company tax credits. The Company recognized $0.4 million, $0.2 million, 
and $0.2 million for interest and penalties in its consolidated statement of operations for the years ended December 31, 2020, 
2019, 2018 respectively.  The Company had liabilities of $1.0 million, $0.6 million, and $0.4 million for interest and penalties 
in  its  consolidated  balance  sheets  as  of  December  31,  2020,  2019,  2018  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  2013  through  2019  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 2017 through 2019 remain open to examination. For states that have a four-year statute of 
limitations,  the  state  income  tax  returns  for  tax  years  2016  through  2019  remain  open  to  examination.  The  Company’s  U.K. 
income tax return for tax year 2019 remains open to examination. The Company believes that an adequate provision has been 
made for any adjustments that may result from tax examinations.

RentPath

On February 11, 2020, the Company and RentPath Holdings, Inc. (“RentPath”) entered into an asset purchase agreement 
(the “Asset Purchase Agreement”) dated as of February 12, 2020. Pursuant to the Asset Purchase Agreement, and subject to the 
terms  and  conditions  set  forth  therein,  the  Company  agreed  to  acquire  for  $588  million  in  cash  all  of  the  equity  interests  of 
RentPath,  upon  the  completion  of  reorganization  of  RentPath  under  Chapter  11  proceedings  in  process  with  the  U.S. 
Bankruptcy Court for the District of Delaware and other closing conditions. As required by the Asset Purchase Agreement, the 
Company paid a $59 million termination fee into a cash escrow account which was payable to the sellers of RentPath in the 
event of certain circumstances resulting the Asset Purchase Agreement being terminated. The break fee deposited into escrow 
was recorded as restricted cash within cash, cash equivalents and restricted cash on the Company's consolidated balance sheets. 
On April 29, 2020, the Company and RentPath each received a request for additional information from the U.S. Federal Trade 
Commission (“FTC”) with respect to the acquisition. The FTC’s additional request extended the waiting period imposed by the 
Hart-Scott  Rodino  Antitrust  Improvements  Act  of  1976  until  the  parties  completed  the  compliance  process  and  the  FTC 
completed its review of the substance of the parties' submission. Bankruptcy court approval was obtained on June 9, 2020. On 
July 29, 2020, the Company exercised its option pursuant to the Asset Purchase Agreement to extend the date after which either 
the Sellers or the Company may terminate the Asset Purchase Agreement if the transaction has not closed (the “Outside Date”) 
for an additional three months until November 12, 2020 in exchange for payment of $7.5 million which was recorded within 
other current assets. On November 30, 2020, the FTC filed an administrative complaint and authorized a suit in federal court 
(which was filed on December 2, 2020), to block the Company's proposed acquisition of RentPath. Subsequently, the Sellers 
notified  the  Company  of  their  intent  to  terminate  the  Asset  Purchase  Agreement  on  December  29,  2020.  The  Company 
terminated  the  Asset  Purchase  Agreement  on  December  31,  2020  as  the  closing  of  the  transactions  contemplated  had  not 
occurred  by  the  Outside  Date.  The  Company  commenced  an  adversary  proceeding  against  Sellers  seeking  a  declaratory 
judgment  that  RentPath  was  in  breach  of  the  Asset  Purchase  Agreement  and  that  the  Company  is  not  obligated  to  pay  the 
termination  fee.  In  February  2021,  the  Company  and  the  Sellers  agreed  that  the  Company  would  pay  $52  million  of  the 
$59  million,  subject  to  bankruptcy  court  approval.  The  Company  recorded  $52  million  termination  fee  and  $7.5  million 
extension  payment  made  to  RentPath  within  selling,  general  and  administrative  expenses  in  consolidated  statement  of 
operations for the year ended December 31, 2020. 

Currently,  and  from  time  to  time,  the  Company  is  involved  in  litigation  incidental  to  the  conduct  of  its  business.  In 
accordance  with  GAAP,  the  Company  records  a  provision  for  a  liability  when  it  is  both  probable  that  a  liability  has  been 
incurred and the amount can be reasonably estimated. While it is reasonably possible that an unfavorable outcome may occur as 
a result of one or more of the Company’s current litigation matters, at this time management has concluded that the resolutions 
of these matters are not expected to have a material effect on the Company's consolidated financial position, future results of 
operations or liquidity. Legal defense costs are expensed as incurred.

SEGMENT REPORTING 

Segment Information

The Company manages its business geographically in two operating segments, with the primary areas of measurement and 
decision-making  being  North  America,  which  includes  the  U.S.  and  Canada,  and  International,  which  primarily  includes 
Europe, Asia-Pacific and Latin America. Management relies on an internal management reporting process that provides revenue 
and  operating  segment  net  income  before  interest  and  other  income  (expense),  loss  on  debt  extinguishment,  income  taxes, 
depreciation and amortization (“EBITDA”). Management believes that operating segment EBITDA is an appropriate measure 
for  evaluating  the  operational  performance  of  the  Company’s  operating  segments.  EBITDA  is  used  by  management  to 
internally  measure  operating  and  management  performance  and  to  evaluate  the  performance  of  the  business.  However,  this 
measure should be considered in addition to, not as a substitute for or superior to, income from operations or other measures of 
financial performance prepared in accordance with GAAP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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, no 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 1.6 million shares were available for future grant under the 2016 Plan as of December 31, 2020.

At December 31, 2020, there was approximately $81 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 2.4 years. The 
income tax benefit realized from stock-based compensation was $20 million, $17 million and $17 million for the years ended 
December  31,  2020,  2019  and  2018,  respectively.  See  Notes  2  and  12  for  further  discussion  of  stock-based  compensation 
expense and income taxes, respectively.

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.  The  aggregate  intrinsic  value  of  options  exercised, 
determined as of the date of option exercise, was approximately $49 million, $40 million and $45 million for the years ended 
December 31, 2020, 2019 and 2018, respectively.

The Company estimated the fair value of each option granted on the date of grant using the Black-Scholes option-pricing 

model, using the assumptions in the following table:

Year Ended December 31,

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.

The 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  achievement  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. 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. 

The  vesting  of  restricted  common  stock  is  subject  to  continuing  employment  requirements.  Certain  performance-based 
restricted common stock awards are also subject to a market condition 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 performance goals and 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 estimates the fair value of its equity 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  market  condition  to  calculate  the  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  awards  with  both  a 
performance and a market condition were as follows:

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

consistent with the performance measurement period of the performance-based restricted common stock awards with a market 
condition.

As  of  December  31,  2020,  the  Company  determined  that  it  was  probable  that  at  least  the  minimum  performance  goals 
associated with restricted stock awards with performance and market conditions granted during 2020, 2019 and 2018 would be 
met by their forfeiture dates. The Company recorded a total of approximately $4 million, $8 million and $5 million of stock-
based compensation expense related to restricted stock awards with a market condition for the years ended December 31, 2020, 
2019 and 2018, respectively. As of December 31, 2020, the Company expects to record an aggregate stock-based compensation 
expense of approximately $6 million for restricted stock awards with a market condition over the periods 2021, 2022 and 2023.

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 Company granted 3,384 and 7441  DSUs during the years 
2020  and  2019,  respectively.  The  expense  related  to  the  Matching  RSUs  is  recognized  over  the  four  years  vesting  period 
following the grant date.

The  Company  maintains  a  401(k)  Plan  (the  “401(k)”)  as  a  defined  contribution  retirement  plan  for  all  eligible 
employees. The 401(k) provides for tax-deferred contributions of employees’ salaries, limited to a maximum annual amount as 
established by the IRS. In addition to the traditional 401(k), effective January 1, 2015, eligible employees have the option of 
making  an  after-tax  contribution  to  a  Roth  401(k)  plan  or  a  combination  of  both.  In  2020,  2019  and  2018,  the  Company 
matched 100% of employee contributions up to a maximum of 4% of total compensation. Amounts contributed to the 401(k) by 
the Company to match employee contributions for the years ended December 31, 2020, 2019 and 2018 were approximately $15 
million, $12 million and $12 million, respectively. The Company had no administrative expenses in connection with the 401(k) 
plan for the years ended December 31, 2020, 2019 and 2018.

Employee Pension Plan

The  Company  maintains  a  Group  Personal  Pension  Plan  (the  “Plan”)  for  all  eligible  employees  in  the  Company’s  U.K. 
offices.  The  Plan  is  a  defined  contribution  plan.  Employees  are  eligible  to  contribute  a  portion  of  their  salaries,  subject  to  a 
maximum  annual  amount  as  established  by  Her  Majesty's  Revenue  and  Customs.  In  2020,  2019  and  2018,  the  Company's 
matching  contribution  was  based  on  the  percentage  contributed  by  the  employee,  up  to  a  maximum  of  6%  of  total 
compensation.  Amounts  contributed  to  the  Plan  by  the  Company  to  match  employee  contributions  for  the  years  ended 
December 31, 2020, 2019 and 2018, were approximately $0.9 million, $0.6 million and $0.5 million, respectively.

Registered Retirement Savings Plan

As of January 1, 2015, the Company introduced a registered retirement savings plan (“RRSP”) for all eligible employees in 
the  Company’s  Canadian  offices.  In  2020,  2019  and  2018,  the  Company  matched  100%  of  employee  contributions  up  to  a 
maximum of 4% of total compensation. Amounts contributed to the RRSP by the Company to match employee contributions 
were approximately $0.1 million for the years ended December 31, 2020, 2019 and 2018.

 Employee Stock Purchase Plan

As of August 1, 2006, the Company introduced an Employee Stock Purchase Plan (“ESPP”), pursuant to which eligible 
employees participating in the plan authorize the Company to withhold specified amounts from the employees’ compensation 
and  use  the  withheld  amounts  to  purchase  shares  of  the  Company's  common  stock  at  90%  of  the  market  price.  Participating 
employees  are  able  to  purchase  common  stock  under  this  plan  during  each  offering  period.  An  offering  period  begins  the 
second  Saturday  before  each  of  the  Company’s  regular  pay  dates  and  ends  on  each  of  the  Company’s  regular  pay  dates.  On 
June 3, 2015, the Company’s stockholders approved an amendment to the ESPP to increase the number of shares available for 
purchase under the ESPP by 100,000 shares. On September 14, 2015, the Company registered the issuance of these additional 
shares under the ESPP pursuant to the registration statement filed September 14, 2015. There were 38,591 and 51,584 shares 
available for purchase under the ESPP as of December 31, 2020 and 2019, respectively, and approximately 12,993 and 13,590 
shares of the Company’s common stock were purchased under the ESPP during 2020 and 2019, respectively.
