Business

PART I

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 the leading online marketplaces for commercial real estate and apartment listings in the U.S. based on 
the number of unique visitors and site visits per month; provide more information, analytics and marketing services than any of 
our competitors and believe that we generate more revenues than any of our commercial real estate information competitors. We 
created  and  compiled  our  standardized  platform  of  information,  analytics  and  online  marketplace  services  where  industry 
professionals  and  consumers  of  commercial  real  estate,  including  apartments,  and  the  related  business  communities,  can 
continuously interact and facilitate transactions by efficiently accessing and exchanging accurate and standardized real estate-
related information. Our service offerings span all commercial property types, including office, retail, industrial, multifamily, 
commercial land, mixed-use and hospitality. We manage our business geographically in two operating segments, with our primary 
areas of measurement and decision-making being North America, which includes the U.S. and parts of Canada, and International, 
which includes parts of the U.K., Spain and France.

Strategy

Our  strategy  is  to  provide  industry  professionals  and  consumers  of  commercial  real  estate  and  apartments  with  critical 
knowledge to explore and complete transactions by offering the most comprehensive, timely and standardized information on 
commercial real estate and apartments and the right tools to be able to effectively utilize that information. Over time, we have 
expanded our services for commercial real estate information, analytics and online marketplaces in an effort to continue to meet 
the needs of this industry as it grows and evolves. We have also extended our offering of comprehensive commercial real estate 
information geographically to include London and other parts of the U.K., Canada, France and Spain, through acquisitions and 
internal growth and development. Information about CoStar’s revenues from, and long-lived assets and total assets located in, 
foreign countries is included in Notes 2 and 12 of the Notes to Consolidated Financial Statements included in this Annual Report 
on Form 10-K. The revenues; net income before interest, income taxes, depreciation and amortization (“EBITDA”); and total 
assets and liabilities for each of our segments are set forth in Note 12 to our consolidated financial statements. Information about 
risks associated with our foreign operations is included in “Item 1A. Risk Factors” and “Item 7A. Quantitative and Qualitative 
Disclosures about Market Risk.”

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

We have five flagship brands - CoStar, LoopNet, Apartments.com, BizBuySell and LandsofAmerica. Our subscription-based 
services consist primarily of information, analytics and online marketplace services offered over the Internet to commercial real 
estate industry and related professionals. Our subscription-based information services consist primarily of CoStar SuiteTM services. 
CoStar Suite is sold as a platform of service offerings consisting of CoStar Property Professional®, CoStar COMPS Professional® 
and CoStar Tenant® and through our mobile application, CoStarGo®. CoStar Suite is our primary service offering in our North 
America and International operating segments. 

Our LoopNet online marketplace enables commercial property owners, landlords, and real estate agents working on their 
behalf to list properties for sale or for lease and to submit detailed information about property listings. The listing process is 
efficient and enables comprehensive information about listed properties to be provided. Commercial real estate agents, buyers 
and tenants use LoopNet extensively to search for available property listings that meet their criteria. We are working to integrate 
the backend systems of the LoopNet and CoStar databases, so that the two services will share a unified database of information. 
We also hope to increase the quantity and quality of the listing information available by enabling select brokers and other industry 
participants to load information directly into the integrated system, simultaneously reducing the time and costs associated with 
researching and maintaining our comprehensive database of commercial real estate information.

 Apartments.comTM is part of our network of apartment marketing sites, which also includes ApartmentFinder.comTM and 
ApartmentHomeLiving.com. Our apartment marketing network of subscription-based services offers renters a searchable database 
of apartment listings and provides professional property management companies and landlords with an advertising destination. 
Our apartment marketing network draws on and leverages CoStar’s multifamily database, which contains detailed information on 
apartment properties. CoStar designed the Apartments.com and ApartmentFinder.com websites, which were launched in February 
2015 and December 2015, respectively, to meet renter preferences and demands, which we believe will drive traffic to those sites 
and attract advertisers who prefer to advertise on heavily trafficked apartment websites. The sites provide a comprehensive selection 
of rentals, information on actual availabilities and rents, and in-depth data on neighborhoods, including restaurants, nightlife, 
history, schools and other facts important to renters. To help renters find the information that meets their needs, the sites also offer 
innovative search tools such as the PolygonTM Search tool, which allows renters to specifically define the area in which they want 
to find an apartment.     

In 2015, we entered into an agreement to be the exclusive third party provider of apartment community listings on the websites 
owned and operated by News Corp. subsidiary Move, Inc.- realtor.com®, Move.com, and Doorsteps.com - with advertiser content 
from Apartments.com and ApartmentFinder.com.  Through this agreement, we are able to promote the apartment communities of 
our advertisers across six major apartment and real estate rental websites, increasing traffic across our network of apartment 
marketing websites, and in turn increasing the lead flow to our advertisers’ communities.

We provide market research and analysis for commercial real estate investors and lenders via our CoStar Portfolio Strategy 
and CoStar Market Analytics service offerings; portfolio and debt analysis, management and reporting capabilities through our 
CoStar Investment Analysis and CoStar Risk Analytics service offerings; and real estate and lease management solutions, including 
lease administration and abstraction services, through our CoStar Real Estate Manager service offerings. We have created and are 
continually  improving  our  standardized  platform  of  information,  analytics  and  online  marketplaces  where  members  of  the 
commercial real estate and related business community can continuously interact and facilitate transactions by efficiently accessing 
and exchanging accurate and standardized commercial real estate information.

Our  standardized  platform  includes  the  most  comprehensive  proprietary  database  in  the  industry;  the  largest  research 
department in the industry; proprietary data collection, information management and quality control systems; a large in-house 
product development team; a broad suite of web-based information, analytics and online marketplaces; a large team of analysts 
and economists; and a large base of clients. Our database has been developed and enhanced for more than 28 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 approximately 100 proprietary databases. Our comprehensive commercial real estate database powers 
our information services, sources data used in our analytic services and provides content for some of our online marketplace 
services. Our ability to utilize the same commercial real estate information across our standardized platform creates efficiencies 
in operations and improves data for our customers.   

Our subscription-based services consist primarily of similar services offered over the Internet to commercial real estate industry 
and related professionals. Our services are typically distributed to our clients under subscription-based license agreements that 
renew automatically, a majority of which have a term of one year. Upon renewal, 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.

Expansion and Growth

Acquisitions

We have continually expanded the geographical coverage of our existing information services and developed new information, 
analytics and online marketplace services. In addition to internal growth, we have grown our business through strategic acquisitions. 
Our more recent acquisitions include the acquisition of LoopNet, an online marketplace that enables property owners, landlords, 
and commercial real estate agents working on their behalf to list properties for sale or for lease and to submit detailed information 
about property listings, in April 2012. On April 1, 2014, we purchased from Classified Ventures, LLC (“CV”) certain assets and 
assumed certain liabilities related to the Apartments.com business (collectively referred to as “Apartments.com”), a national online 
apartment rentals resource for renters, property managers and owners. On June 1, 2015, to further support our expansion into the 
multifamily vertical, we acquired Network Communications, Inc. (“NCI”), including its Apartment Finder business (collectively 
referred to as “Apartment Finder”). Apartment Finder provides lead generation, advertising, and Internet marketing solutions to 
property  managers  and  owners  through  its  main  service, ApartmentFinder.com.  Further,  on  July  1,  2015,  we  expanded  our 
International services into Madrid through the acquisition of the assets of Belbex Corporate, S.L., a small commercial real estate 
information provider operating in Madrid, Spain.

Development and Expansion

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

The launch of the improved Apartments.com website in February 2015 and the new ApartmentFinder.com website in December 
2015 are examples of our software development efforts to improve existing services, introduce new services, integrate products 
and  services,  and  cross-sell  existing  services.  We  believe  the  improved  sites,  enhanced  search  capabilities,  availability  of 
information  regarding  real-time  vacancies,  and  our  continued  development  and  introduction  of  enhancements  to  our  online 
apartment rental marketplaces will attract more consumers, making these sites more attractive to property managers, which will 
increase our cross-selling opportunities. Our software development initiatives in 2015 included enhancing our new CoStar Lease 
Analysis® integrated workflow tool to provide users a simple way to produce understandable cash flows for leases, and to enhance 
other lease comparable services. We believe greater functionality makes our services valuable to an even broader audience and 
helps us increase sales of our services to brokers, banks, owners and institutional investors. We expect technology enhancements 
to drive continued revenue growth in 2016 and for the foreseeable future.

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. For example, 
we recently eliminated certain Apartment Finder services and phased out Apartment Finder print advertising and moved to an all-
digital offering. We expect a short-term reduction in revenues and associated costs resulting from the elimination of these Apartment 
Finder services. Additionally, we are working to integrate the backend systems of the LoopNet and CoStar databases, so that the 
two services will share a unified database of information in order to create efficiencies in operations and improved data for our 
customers. We also continue to assess whether to transition the LoopNet marketplace to a pure marketing site for commercial real 
estate where, eventually, all listings would be paid and users could search the site for free. If and when we implement such a shift, 
we will seek to convert LoopNet marketplace customers to higher value, more profitable annual subscription information services, 
which should increase revenues and earnings over time. However, we cannot predict with certainty the amount or timing of any 
reductions in revenues and earnings or subsequent increases in revenues and earnings, if any, resulting from any eliminations or 
phasing out of the LoopNet information services or any other service offering, if implemented.

Our revenues have increased as a result of revenue from acquired businesses and from cross-selling opportunities among the 
customers of CoStar and the acquired companies. We expect to continue to increase revenues as a result of such cross-selling 
opportunities. We may incur increased expenses in connection with any marketing and sales campaigns involving cross-selling 
opportunities and initiatives, and in connection with promotion of our new services and brands.

We are expanding the geographic reach of our North America services. In 2014, we began offering our services in Toronto, 
Canada. Building on our experience in Toronto, we have expanded and are continuing to expand our research into additional 
Canadian cities. In the second quarter of 2015, we began offering services in Calgary and Vancouver and are currently researching 
commercial real estate in the Canadian cities of Ottawa and Edmonton. Further, on July 1, 2015, we expanded our International 
services into Madrid through the acquisition of the assets of Belbex Corporate, S.L., a small commercial real estate information 
provider operating in Madrid, Spain. We believe that our integration efforts and continued investments in our services, including 
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 in North America and internationally. We plan to continue to invest in, evaluate and strategically position our sales force 
as the Company continues to develop and grow. We are also investing in our research capacity to support continued growth of our 
information and analytics offerings, to support Apartments.com and Apartment Finder, to expand into additional Canadian markets 
and to provide services in Madrid, Spain. While we believe investments we make in our business create a platform for growth, 
those investments may reduce our profitability and adversely affect our financial position.    

We intend to continue to assess the need for additional investments in our business, in addition to the investments discussed 
above in order to develop and distribute new services within our current platform, expand the reach of our current service offerings 
or  to  integrate  new  or  current  offerings  to  provide  a  more  robust,  efficient  or  complete  service  offering. Any  future  product 
development or expansion of services, combination and coordination of services or elimination of services or internal expansion, 
development or restructuring efforts could reduce our profitability and increase our capital expenditures. Any new investments, 
changes to our service offerings or other unforeseen events could cause us to generate losses and negative cash flow from operations 
in the future. We expect to continue our software development efforts to improve existing services, introduce new services, integrate 
products and services, cross-sell existing services, and expand and develop supporting technologies for our research and sales and 
marketing  organizations.  We  are  committed  to  supporting  and  improving  our  information,  analytics  and  online  marketplace 
solutions. 

Industry Overview

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

7

A large number of parties involved in the commercial real estate and related business community make use of the services 

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

• Sales and leasing 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 bankers

• Commercial bankers
• Mortgage bankers
• Mortgage brokers

• Retailers

• Building services vendors

• Communications providers

•
•

•

Insurance companies’ managers

Institutional advisors

Investors and asset managers

The commercial real estate and related business community generally has 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, collect data on specific markets and develop 
software  to  analyze  the  information  they  have  independently  gathered. This  highly  fragmented  methodology  has  resulted  in 
duplication of effort in the collection and analysis of information, excessive internal cost and the creation of non-standardized 
data containing varying degrees of accuracy and comprehensiveness, resulting in a formidable information gap. 

The  creation  of  a  standardized  information  platform  for  commercial  real  estate  requires  an  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 and outside contractors, our experienced team of analysts 
and economists, technological expertise and broad customer base, we believe that we have created such a platform.

Within the apartment rental community, most apartment websites primarily supply only the listings that property owners pay 
to advertise and often return results that are inconsistent with the renter's search criteria. These limited results generally do not 
provide information about the actual rental availabilities. We believe that consumers expect accurate, actionable and comprehensive 
apartment rental information. To create the Apartments.com website and the ApartmentFinder.com website, we have drawn on 
our multifamily database and undertaken a research effort collecting and verifying information and visiting and photographing 
properties. With the launch of the improved Apartments.com website and the new ApartmentFinder.com website, we believe that 
we have created easily searchable sites with a comprehensive selection of rentals, information on actual rental availabilities and 
rents, and in-depth data on neighborhoods, including restaurants, nightlife, history, schools and other important facts.

CoStar’s Comprehensive Database

CoStar has spent more than 28 years building and acquiring a database 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 apartment tours, plat maps and floor plans.

CoStar Research

We have developed a sophisticated data collection organization utilizing a multi-faceted research process. In 2015, our full 
time researchers and contractors conducted millions of interviews of brokers, owners, tenants, apartment community owners and 
property managers.

8

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

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

CoStar has an extensive field research effort that includes physical inspection of properties in order to research new markets, 
find additional property inventory, photograph properties and verify existing information. In 2015, our field researchers drove 
millions of miles and conducted hundreds of thousands of on-site building inspections. CoStar's field research effort also includes 
creating  high  quality  videos  of  interior  spaces  (including  walk-through  videos  and  3D  virtual  apartment  tours  of  apartment 
communities), amenities and exterior features of properties. CoStar utilizes high-tech, field research vehicles across the U.S., 
Canada and the U.K. A significant majority of these vehicles are customized, energy efficient hybrid cars that are equipped with 
computers, proprietary Global Positioning System tracking software, high resolution digital cameras and handheld laser instruments 
to help precisely measure buildings, geo-code them and position them on digital maps. Each CoStar vehicle uses wireless technology 
to track and transmit field data. A typical site inspection consists of photographing the building, measuring the building, geo-
coding the building, capturing “For Sale” or “For Lease” sign information, counting parking spaces, assessing property condition 
and construction, and gathering tenant information. Certain researchers canvass properties, collecting tenant data suite by suite. 
We also utilize a low-flying airplane 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.  

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 provide for our use of a variety of commercial real estate information, 
including property ownership, tenant information, demographic information, maps, aerial photographs and 3D virtual apartment 
tours of apartment communities, all of which enhance various CoStar services. These license agreements generally grant us a non-
exclusive  license  to  use  the  data  and  images  in  the  creation  and  supplementation  of  our  information,  analytics  and  online 
marketplaces and include what we believe are standard terms, such as a contract term ranging from one to five years, automatic 
renewal of the contract and fixed periodic license fees or a combination of fixed periodic license fees plus additional fees based 
upon our usage.

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 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.

Proprietary Technology

CoStar’s information technology professionals focus on developing new services for our customers, improving and maintaining 
existing services, integrating our current services, securing our comprehensive database of commercial real estate information and 
delivering research automation tools that improve the quality of our data and increase the efficiency of our research analysts.

customer support and accounting information. We use this system to maintain our commercial real estate research information, 
manage contacts with the commercial real estate community, provide research workflow automation and conduct daily automated 
quality assurance checks. In addition, our information technology team has also developed fraud-detection technology to detect 
and prevent unauthorized access to our services.

Our information technology professionals maintain the servers and network components necessary to support CoStar services 
and  research  systems. CoStar's  core  services  are  served  from  multiple  data  centers  to  support  uninterrupted  service  for  our

off-site storage and other protective measures in an effort to ensure the availability and security of all core systems. 

Services

Our suite of information, analytics and online marketplaces is branded and marketed to our customers. Our services are 
primarily derived from a database of building-specific information and offer customers specialized tools for accessing, analyzing 
and using our information. Over time, we expect to continue to enhance our existing information, analytics and online marketplaces 
and develop additional services that make use of our comprehensive database to meet the needs of our existing customers as well 
as potential new categories of customers.

Our principal information, analytics and online marketplaces as of January 29, 2016, are described in the following paragraphs:

trends based on user selected variables. CoStar Property provides subscribers with powerful map-based search capabilities as well 
as  a  user  controlled,  password  protected  extranet  (or  electronic  “file  cabinet”)  where  brokers  may  share  space  surveys  and 
transaction-related documents online, in real time, with team members. When used together with CoStar Connect®, CoStar Property 
enables subscribers to share space surveys and transaction-related documents with their clients, accessed through their corporate 
website. CoStar Property, along with all of CoStar’s other core information, analytics and online marketplaces, is delivered solely

CoStar Advertising®   CoStar Advertising offers property owners and brokers a highly targeted and cost effective way to 
market a space for lease or a property for sale directly to CoStar subscribers looking for that type of space through interactive 
advertising. Our advertising model is based on varying levels of exposure, enabling the advertiser to target as narrowly or broadly 
as its budget permits. With the CoStar Advertising program, when the advertiser’s listings appear in a results set, they receive 
priority positioning and are enhanced to stand out. The advertiser can also purchase exposure in additional submarkets, or the 
entire market area so that this ad will appear even when this listing would not be returned in a results set.

Clients

We draw clients from across the commercial real estate and related business community, including commercial real estate 
brokers, owners, developers, landlords, property managers, financial institutions, retailers, vendors, appraisers, investment banks, 
government agencies and other parties involved in commercial real estate. For the years ended December 31, 2013, 2014 and 
2015, no single client accounted for more than 5% of our revenues.

Sales and Marketing

Our sales teams are primarily located in field sales offices throughout the U.S. and in offices outside of the U.S., including, 
among others, London, England and Glasgow, Scotland. Our inside sales teams are located in our Washington, DC; San Francisco, 
California; and Chicago, Illinois offices. These teams prospect for new clients and perform product and service demonstrations 
exclusively by telephone and over the Internet to support the direct sales force.

Our local offices typically serve as the platform for our in-market sales, customer support and field research operations for 
their respective regions. The sales force is responsible for selling to new prospects, training new and existing clients, providing 
ongoing customer support, renewing existing client contracts and identifying cross-selling opportunities. In addition, the sales 
force has primary front line responsibility for customer care. Our customer service and support staff is charged with ensuring high 
client satisfaction by providing ongoing customer support. In 2016, we began to form a customer relationship team consisting of 
client relationship managers in the sales organization, to drive even greater usage of our products and services. The client relationship 
managers are responsible for training existing users, sharing market specific research with clients, ensuring accurate and timely 
listings and ensuring client driven product enhancement ideas are shared with our product development team. 

Our sales strategy is to aggressively attract new clients, while providing ongoing incentives for existing clients to subscribe 
to additional products and services in order to achieve high renewal rates. We actively manage client accounts in order to retain 
clients by providing frequent service demonstrations as well as company-client contact and communication. We place a premium 
on training new and existing client personnel on the use of our services so as to promote maximum client utilization and satisfaction 
with our services. Our strategy also involves entering into multi-year, multi-market license agreements with our larger clients.

13

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, the number and types of services to which a client subscribes, the number of properties 
a client advertises and the prominence and placement of a client's advertised properties in the search results. Our subscription 
clients generally pay contract fees on a monthly basis, but in some cases may pay us on a quarterly or annual basis.

Our  primary  marketing  methods  include:  service  demonstrations;  face  to  face  networking;  web-based  marketing;  direct 
marketing; communication via our corporate website and news services; participation in trade show and industry events; Company-
sponsored  events;  print  advertising  in  trade  magazines  and  other  business  publications;  client  referrals;  CoStar AdvisorTM, 
LoopNewsTM  and  other  company  newsletters  distributed  via  email  to  our  clients  and  prospects.  We  launched  an  improved 
Apartments.com website in February 2015 and we recently launched a new ApartmentFinder.com website in December 2015, 
each of which has a cleaner look, information about actual rental availabilities, rents and other fees, and better search functionality. 
In conjunction with the launch of the improved Apartments.com website, we embarked on a wide-scale marketing campaign in 
2015 to generate brand awareness and site traffic for Apartments.com. The marketing campaign featured television and radio 
advertising, online/digital advertising, social media and out-of-home ads and was reinforced by Search Engine Marketing. We 
currently plan to continue to utilize these marketing methods.

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

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

Our sales and marketing efforts have focused and will continue to focus on cross-selling and marketing our services. Similar 
to our prior acquisitions, we have been cross-selling, and plan to continue to cross-sell, the services offered by Apartments.com 
and ApartmentFinder.com and the other services we offer, including but not limited to CoStar Market Analytics. 

Competition

The market for information, analytics and online marketplaces generally is competitive and rapidly changing. 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;
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.

14

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

• 

• 

• 

• 

• 

• 

• 

• 

online marketing services or websites targeted to commercial real estate brokers, buyers and sellers of commercial real 
estate properties, insurance companies, mortgage brokers and lenders, such as commercialsearch.com, PropertyLine.com, 
Reed Business Information Limited, officespace.com, MrOfficeSpace.com, TenantWise, www.propertyshark.com, Rofo, 
BuildingSearch.com, CIMLS, CompStak, Rightmove, WorkplaceIQ, RealPoint LLC, estatesgazette.com, and DebtX;

publishers and distributors of information, analytics and marketing services, including regional providers and national 
print publications, such as Xceligent, eProperty Data, CBRE Economic Advisors, Marshall & Swift, Yale Robbins, Reis, 
Real Capital Analytics, The Smith Guide, Yardi Matrix, Axiometrics, Inc., ReScour, Inc., and RealMassive;

Internet listing services featuring apartments for rent, such as ApartmentGuide.com, ForRent.com, Zillow Rentals, Trulia 
Rent, Craigslist, ApartmentList.com, Rent.com, and Move.com;   

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

real estate portfolio management software solutions, such as Cougar Software, MRI Software, Altus, and Intuit;

real  estate  lease  management  and  administration  software  solutions,  such  as Accruent, Tririga,  Manhattan  Software, 
Lucemex, and AMT;

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, 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.

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.

15

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 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  Property®,  CoStar  COMPS  Professional®,  CoStar Tenant®,  CoStarGo®,  CoStar  Lease Analysis®,  CoStar 
Showcase®, and LoopNet®, 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 and seven patents in the U.S. which 
expire in 2020, 2021 (2 patents), 2022 (2 patents), 2025 and 2032, respectively, covering, among other things, critical elements 
of CoStar’s proprietary field research technology and mapping tools. 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 on our portfolio of patents as a 
whole.

Employees

As of January 29, 2016, we employed 2,631 employees. None of our employees are represented by a labor union. We have 

experienced no work stoppages. We believe that our employee relations are excellent.

forward-looking statements to reflect new information or events or circumstances after the date of this Report or to reflect the 
occurrence of unanticipated events.

Risk Factors

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

17

 
A downturn or consolidation in the commercial real estate industry may decrease customer demand for our services. The 
commercial real estate market may be adversely impacted by many different factors, including lower than expected job growth 
or job losses resulting in reduced real estate demand; rising interest rates and slowing transaction volumes that negatively impact 
investment returns; excessive speculative new construction in localized markets resulting in increased vacancy rates and diminished 
rent growth; and unanticipated disasters and other adverse events such as slowing of the growth in the working age population 
resulting in reduced demand for all types of real estate. A reversal of improvements in the commercial real estate industry’s leasing 
activity and absorption rates or a renewed downturn in the commercial real estate market may affect our ability to generate revenues 
and may lead to more cancellations by our current or future customers, either of which could cause our revenues or our revenue 
growth rate to decline and reduce our profitability. A depressed commercial real estate market has a negative impact on our core 
customer base, which could decrease demand for our information, analytics and online marketplaces. Also, companies in this 
industry may consolidate, often in order to reduce expenses. Consolidation, or other cost-cutting measures by our customers, may 
lead to cancellations of our information, analytics and online marketplace services by our customers, reduce the number of our 
existing clients, reduce the size of our target market or increase our clients’ bargaining power, all of which could cause our revenues 
to decline and reduce our profitability. If cancellations, reductions of services, and failures to pay increase, and we are unable to 
offset the resulting decrease in revenue by increasing sales to new or existing customers, our revenues may decline or grow at 
lower rates.

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

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

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

18

We may be unable to increase awareness of our brands, including CoStar, LoopNet, Apartments.com, Apartment Finder, 
BizBuySell and LandsofAmerica, which could adversely affect our business. We rely heavily on our brands, which we believe are 
key assets of our company. Awareness and differentiation of our brands are important for attracting and expanding the number of 
users of, and subscribers to, our online marketplaces, such as LoopNet, the Apartments.com network of rental websites, CoStar 
Showcase, LandandFarm.com and LandsofAmerica.com. We expect to continue to invest in sales and marketing, including sales 
and marketing for our other brands 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. Our recent investments 
in sales and marketing activities to increase brand awareness and grow site traffic to the Apartments.com network of rental websites 
may not be successful. If we are unable to maintain or enhance user and advertiser awareness of our brands, or if we are unable 
to  recover  our  marketing  and  advertising  costs  through  increased  usage  of  our  services  and  increased  advertising  on  the 
Apartments.com network of rental websites, our business, results of operations and financial condition could be adversely affected.

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

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 revenue from our marketplace businesses depends, in part, on our ability to attract users to our 
websites. If we fail to maintain or increase traffic to our marketplaces, our ability to acquire additional subscribers or advertisers 
and deliver leads to existing subscribers and advertisers could be adversely affected. Our marketing expenses have increased and 
may continue to increase in connection with our efforts to maintain or increase traffic to our websites. Our efforts to maintain or 
generate additional traffic to our marketplaces may not be successful. Even if we are able to attract additional users, increases in 
our operating expenses could negatively impact our operating results if we are unable to generate more revenue through increased 
sales of subscriptions to our marketplace products. We face competition to attract users to our marketplace websites. Our existing 
and potential competitors include companies that could devote greater technical and other resources than we have available to 
provide services that users might view as superior to our offerings. Any of our future or existing competitors may introduce different 
solutions that attract users away from our services or provide solutions similar to our own that have the advantage of better branding 
or marketing resources. If we are unable to increase traffic to our marketplaces, or if we are unable to generate enough additional 
revenue to offset increases in expenses related to increasing traffic to our marketplaces, our business and operating results could 
be adversely affected.

If real estate professionals or other advertisers reduce or cancel their advertising spending with us and we are unable to 
attract  new  advertisers,  our  operating  results  would  be  harmed.    Our  marketplace  businesses,  including  LoopNet,  the 
Apartments.com  network  of  rental  websites,  CoStar  Showcase,  LandandFarm.com  and  LandsofAmerica.com,  depend  on 
advertising revenue 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  increased  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 spending with us.

19

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.

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

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

If we are not able to successfully finance and/or integrate acquisitions, our business operations and financial position could 
be adversely affected. We have expanded our markets and services in part through acquisitions of complementary businesses, 
services, databases and technologies, and expect to continue to do so in the future. Our strategy to acquire complementary companies 
or assets depends on our ability to identify, and the availability of, suitable acquisition candidates. We may incur costs in the 
preliminary stages of an acquisition, but may ultimately be unable or unwilling to consummate the proposed transaction for various 
reasons. In addition, acquisitions involve numerous risks, including the ability to realize or capitalize on synergies created through 
combinations; managing the integration of personnel and products; potential increases in operating costs; managing geographically 
remote operations; the diversion of management’s attention from other business concerns and potential disruptions in ongoing 
operations during integration; the inherent risks in entering markets and sectors in which we have either limited or no direct 
experience; and the potential loss of 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. Acquisitions could result in dilutive issuances of equity securities, the incurrence of debt, one-time write-offs 
of goodwill and substantial amortization expenses of other intangible assets. We may be unable to obtain financing on favorable 
terms,  or  at  all,  if  necessary  to  finance  future  acquisitions  making  it  impossible  or  more  costly  to  acquire  complementary 
businesses. 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, and the terms of such regulatory approvals 
may impose limitations on our ongoing operations or require us to divest assets or lines of business.

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

The failure to successfully integrate Apartments.com or Apartment Finder and/or fully realize expected synergies from those 
acquisitions in the expected time frames or at all may adversely affect our future results and our business. The success of the 
Apartments.com and Apartment Finder acquisitions depends, in part, on our ability to successfully integrate those businesses and 
realize the benefits and synergies we anticipate to result from the combination of our business and the businesses of Apartments.com 
and Apartment Finder, including anticipated growth opportunities and cost savings. We may not be able to achieve these objectives 
in whole or in part, achievement of the objectives may take longer than expected, or achievement of the objectives may be more 
costly than expected. Any failure to timely realize these anticipated benefits could have a material adverse effect on our revenues, 
expenses and operating results.

20

The success of the Apartments.com and Apartment Finder acquisitions will also depend in part on our ability to minimize or 
eliminate any difficulties that may occur in connection with the integration of our business and those acquired businesses. The 
integration process could result in the loss of key employees, loss of key clients, loss of key vendors and other business partners, 
increases in operating costs, increases in taxes, or the disruption of each company's ongoing businesses, any or all of which could 
adversely affect our ability to achieve the anticipated benefits and synergies of the respective acquisition. Our efforts to integrate 
the businesses may divert management's attention and other resources from uses that could otherwise have been beneficial to the 
Company. In addition, management may decide to combine or eliminate products or services currently offered by one of the 
acquired businesses, which could also result in the loss of revenues, key employees, key clients, key vendors or other business 
partners.

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

We may not be able to successfully introduce new or upgraded information, analytics and online marketplace services or 
combine or shift focus from services with less demand, which could decrease our revenues and our profitability. Our future business 
and financial success will depend on our ability to continue to anticipate the needs of, and to introduce new and upgraded services 
into  the  marketplace. To  be  successful,  we  must  adapt  to  changes  in  the  industry,  as  well  as  rapid  technological  changes  by 
continually  enhancing  our  information,  analytics  and  online  marketplace  services.  Developing  new  services  and  upgrades  to 
services, as well as integrating and coordinating current services, imposes heavy burdens on our systems department, management 
and researchers. The processes are costly, and our efforts to develop, integrate and enhance our services may not be successful. 
As we continue to combine our operations with those that we have acquired, we must continue to assess the purposes for which 
various services may be used alone or together, and how we can best address those uses through stand-alone services or combinations 
or coordinating applications thereof. In addition, successfully launching and selling a new or upgraded service puts pressure on 
our sales and marketing resources. In February 2015, we launched the improved Apartments.com website and in December 2015, 
we launched  the new ApartmentFinder.com website, both after undergoing  extensive product development. In  2015, we also 
launched a wide-scale marketing campaign in an effort to increase brand awareness and site traffic for Apartments.com. The launch 
of the sites and/or the marketing campaign may not result in increased brand awareness, site traffic and/or revenues. If we are 
unsuccessful in obtaining greater market share, we may not be able to offset the expenses associated with the new launch and 
marketing campaign, which could have a material adverse effect on our financial results.

If we are unable to develop new or upgraded services or decide to combine, shift focus from, or phase out a service that 
overlaps or is redundant with other services we offer, then our customers may choose a competitive service over ours and our 
revenues may decline and our profitability may be reduced. For example, we continue to assess whether to transition the LoopNet 
marketplace to a pure marketing site for commercial real estate where, eventually, all listings would be paid and users could search 
the site for free. We would expect to see a short-term reduction in revenues and earnings if we implement this transition. Although 
we are assessing the best strategy to implement this shift and will seek to convert customers to higher value, more profitable annual 
subscription information services, which should increase revenues and earnings over time, we cannot predict with certainty whether 
we will be successful in shifting customers to higher value, more profitable subscriptions and, consequently, in offsetting any 
reduction in revenue and earnings; therefore, if we make this transition, our revenues and earnings may ultimately decline. In 
addition, if we incur significant costs in developing new or upgraded services or combining and coordinating existing services, 
we are not successful in marketing and selling these new services or upgrades, or our customers fail to accept these new or combined 
and coordinating services, it could have a material adverse effect on our results of operations by decreasing our revenues and 
reducing our profitability.

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

21

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

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

Effective trademark, trade secret, patent, and copyright protection may not be available in every country in which our services 
may be provided.  The laws of certain countries do not protect proprietary rights to the same extent as the laws of the United States 
and,  therefore,  in  certain  jurisdictions,  we  may  be  unable  to  protect  our  intellectual  property  and  our  proprietary  technology 
adequately against unauthorized third-party copying or use, which could harm our competitive position. 

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

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

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

22

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

Our actual or perceived failure to comply with privacy laws and standards could adversely affect our business, financial 
condition and results of operations. We are dependent on information technology networks and systems to process, transmit, and 
store electronic information and to communicate between our locations around the world and with our clients. We collect, use and 
disclose personally identifiable information, including among other things names, addresses, phone numbers, and email addresses. 
We also collect, store and use sensitive or confidential transaction information and, in certain circumstances, credit card information. 
As a result, we are subject to a variety of state, national, foreign, and international laws and regulations that apply to the collection, 
use, retention, protection, disclosure, transfer and other processing of personal data. These privacy- and data protection-related 
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. Compliance with these laws and regulations can be costly and can 
delay or impede the development of new products.

The U.S.-EU Safe Harbor Framework, which established means for legitimizing the transfer of personal data by U.S. companies 
from the European Economic Area, or EEA, to the U.S., recently was invalidated by a decision of the European Court of Justice, 
or the ECJ. In light of the ECJ’s decision, we have begun to undertake efforts to conform transfers of personal data from the EEA 
based on current regulatory obligations, the guidance of data protection authorities and evolving best practices. We continue to 
review our business practices and the evolving regulations and may find it necessary or desirable to make further changes to our 
personal data handling or engage in additional efforts to cause our transfer and receipt of EEA residents’ personal data to be 
legitimized under applicable European law.  We may find it necessary to establish systems to maintain EU-origin data in the 
European Economic Area, which may involve substantial expense and distraction from other aspects of our business.  

Despite our efforts, we may be unsuccessful in establishing legitimate means of transferring certain data from the EEA, 
including due to ongoing legislative activity, which may vary the current data protection landscape. Our actual or alleged failure 
to comply with applicable privacy or data security laws, regulations and policies, or to protect personal data, could result in 
enforcement actions and significant penalties against us, which could result in negative publicity, increase our operating costs, 
subject us to claims or other remedies and have a material adverse effect on our business, financial condition, and results of 
operations.

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

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

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

23

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

We depend on processing vendors to complete credit and debit card transactions. If we or our processing vendors fail to maintain 
adequate systems for the authorization and processing of credit card transactions, it could cause one or more of the major credit 
card companies to disallow our continued use of their payment products. We could lose customers if we are not able to continue 
to use payment products of the major credit card companies. In addition, if the systems for the authorization and processing of 
credit card transactions fail to work properly and, as a result, we do not charge our customers’ credit cards on a timely basis or at 
all, our business, revenue, results of operations and financial condition could be harmed.  

We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds 
transfers, which could change or be reinterpreted in ways that make it more difficult for us to comply. We are required to comply 
with payment card industry security standards. Failing to comply with those standards may violate payment card association 
operating rules, federal and state laws and regulations, and the terms of our contracts with payment processors. Any failure to 
comply also may subject us to fines, penalties, damages and civil liability, and may result in the loss of our ability to accept credit 
and debit card payments. Further, there is no guarantee that such compliance will prevent illegal or improper use of our payment 
systems or the theft, loss, or misuse of data pertaining to credit and debit cards, card holders and transactions.  If we fail to 
adequately control fraudulent credit card transactions, we may face civil liability, diminished public perception of our security 
measures, and significantly higher credit card-related costs, each of which could harm our business, results of operations and 
financial condition. 

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

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

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

• 
• 
• 
• 

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

These types of events or indicators and the resulting impairment analysis could result in goodwill impairment charges in the 
future, which would reduce our profitability. Impairment charges could negatively affect our financial results in the periods of 
such charges, which may reduce our profitability. As of December 31, 2015, we had approximately $1.3 billion of goodwill, 
including $1.2 billion in our North America segment and $25.6 million in our International segment.

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

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

The number of LoopNet's registered members is higher than the number of actual members. The number of registered members 
in LoopNet's network is higher than the number of actual members because some members have multiple registrations or others 
may have registered under fictitious names. Given the challenges inherent in identifying these accounts, we do not have a reliable 
system to accurately identify the number of actual members, and thus we rely on the number of registered members as a measure 
of the size of the LoopNet marketplace. If the number of LoopNet's actual members does not continue to grow and those members 
do not convert to premium members, then the LoopNet marketplace business may not grow as fast as we expect, which could 
harm our operating and financial results.

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

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

25

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; difficulties in managing foreign operations; limited protection for intellectual 
property rights in some countries; difficulty in collecting accounts receivable and longer collection periods; costs of enforcing 
contractual obligations; impact of recessions in economies outside the U.S.; and potentially adverse tax consequences. In addition, 
international expansion imposes additional burdens on our executive and administrative personnel, systems development, research 
and sales departments, and general managerial resources. If we are not able to manage our international operations successfully, 
we may incur higher expenses and our profitability may be reduced. Finally, the investment required for additional international 
expansion could exceed the profit generated from such expansion, which would reduce our profitability and adversely affect our 
financial position.

Fluctuating foreign currencies may negatively impact our business, results of operations and financial position. Due to our 
acquisitions  of  CoStar  U.K.  Limited  (formerly  FOCUS  Information  Limited),  Property  and  Portfolio  Research  Ltd.,  Grecam 
S.A.S., and the assets of Belbex Corporate, S.L., as well as our expansion into Canada, a portion of our business is denominated 
in the British Pound, Euro and Canadian dollar. As a result, fluctuations in foreign currencies may have an impact on our business, 
results  of  operations  and  financial  position. Foreign  currency  exchange  rates  have  fluctuated  and  may  continue  to 
fluctuate. Significant foreign currency exchange rate fluctuations may negatively impact our international revenue, which in turn 
affects  our  consolidated  revenue. Currencies  may  be  affected  by  internal  factors,  general  economic  conditions  and  external 
developments in other countries, all of which can have an adverse impact on a country’s currency. Currently, we are not party to 
any  hedging  transactions  intended  to  reduce  our  exposure  to  exchange  rate  fluctuations. We  may  seek  to  enter  into  hedging 
transactions in the future, but we may be unable to enter into these transactions successfully, on acceptable terms or at all. We 
cannot predict whether we will incur foreign exchange losses in the future. Further, significant foreign exchange fluctuations 
resulting in a decline in the respective, local currency may decrease the value of our foreign assets, as well as decrease our revenues 
and earnings from our foreign subsidiaries, which would reduce our profitability and adversely affect our financial position.

Our indebtedness could adversely affect us, including by decreasing our business flexibility and increasing our costs. On 
April 1, 2014, we entered into the 2014 Credit Agreement by and among CoStar, as borrower, CoStar Realty Information, Inc., 
as co-borrower, the lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as administrative agent. The 2014 
Credit Agreement provides for a $400.0 million term loan facility and a $225.0 million revolving credit facility, each with a term 
of five years. We used the proceeds of the term loan facility and $150.0 million of the initial borrowing under the revolving credit 
facility to refinance the term loan facility and revolving credit facility established under a credit agreement dated February 16, 
2012 (the “2012 Credit Agreement”), including related fees and expenses, and pay a portion of the consideration and transaction 
costs related to the Apartments.com acquisition. The 2014 Credit Agreement contains customary restrictive covenants imposing 
operating and financial restrictions on us, including restrictions that may limit our ability to engage in acts that we believe may 
be in our long-term best interests. These covenants restrict our ability and the ability of our subsidiaries to (i) incur additional 
indebtedness, (ii) create, incur, assume or permit to exist any liens, (iii) enter into mergers, consolidations or similar transactions, 
(iv) make investments and acquisitions, (v) make certain dispositions of assets, (vi) make dividends, distributions and prepayments 
of certain indebtedness, and (vii) enter into certain transactions with affiliates.

The operating restrictions and financial covenants in the 2014 Credit Agreement and any future financing agreements may 
limit our ability to finance future operations or capital needs, to engage in other business activities or to respond to changes in 
market conditions. Our ability to comply with any financial covenants could be affected materially by events beyond our control, 
and we may be unable to satisfy any such requirements. If we fail to comply with these covenants, we may need to seek waivers 
or amendments of such covenants, seek alternative or additional sources of financing or reduce our expenditures. We may be 
unable to obtain such waivers, amendments or alternative or additional financing on a timely basis or at all, or on favorable terms.

We are required to make periodic principal and interest payments pursuant to the terms of the 2014 Credit Agreement.  If an 
event of default occurs, the interest rate on overdue amounts will increase and the lenders under the 2014 Credit Agreement may 
declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable and may 
exercise remedies in respect of the collateral. We may not be able to repay all amounts due under the 2014 Credit Agreement in 
the event these amounts are declared due upon an event of default.

26

Negative conditions in the global credit markets may affect the liquidity of a portion of our long-term investments.  Currently, 
our long-term investments include mostly AAA-rated auction rate securities (“ARS”), which are primarily student loan securities 
supported by guarantees from the Federal Family Education Loan Program (“FFELP”) of the U.S. Department of Education. 
Continuing negative conditions in the global credit markets have prevented some investors from liquidating their holdings of 
auction rate securities because the amount of securities submitted for sale has exceeded the amount of purchase orders for such 
securities. As of December 31, 2015, we held $16.8 million par value of ARS, all of which failed to settle at auctions. When an 
auction fails for ARS in which we have invested, we may be unable to liquidate some or all of these securities at par. In the event 
we need or desire to immediately access these funds, we will not be able to do so until a future auction on these investments is 
successful, a buyer is found outside the auction process or an alternative action is determined. If a buyer is found but is unwilling 
to purchase the investments at par, we may incur a loss, which would reduce our profitability and adversely affect our financial 
position.

Our ARS investments are not currently actively trading and therefore do not currently have a readily determinable market 
value. The estimated fair value of the ARS no longer approximates par value. We have used a discounted cash flow model to 
determine the estimated fair value of our investment in ARS as of December 31, 2015. The assumptions used in preparing the 
discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of cash flows, liquidity risk 
premiums, expected holding periods and default risk of the ARS. We update the discounted cash flow model on a quarterly basis 
to reflect any changes in the assumptions used in the model and settlements of ARS investments that occurred during the period. 
Based on this assessment of fair value, as of December 31, 2015, we determined there was a net decline in the fair value of our 
ARS investments of approximately $435,000. The decline was deemed to be a temporary impairment and was recorded as an 
unrealized  loss  in  accumulated  other  comprehensive  loss  in  stockholders’  equity. If  the  issuers of  these ARS  are  unable  to 
successfully close future auctions and/or their credit ratings deteriorate, we may be required to record additional unrealized losses 
in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments, which 
would reduce our profitability and adversely affect our financial position.

We have not made any material changes in the accounting methodology used to determine the fair value of the ARS. We do 
not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used 
to calculate the fair value of the ARS as of December 31, 2015. However, if changes in these assumptions occur, and, should those 
changes be significant, we may be required to record additional unrealized losses in accumulated other comprehensive loss or an 
other-than-temporary impairment charge to earnings on these investments.

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

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

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

27

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

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

Our operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to seasonality 
and market cyclicality, each of which could cause our stock price to be negatively affected. The commercial real estate market 
may be influenced by general economic conditions, economic cycles, annual seasonality factors and many other factors, which 
in turn may impact our financial results. The market is large and fragmented. The different sectors of the industry, such as office, 
industrial, retail, multifamily, and others, are influenced differently by different factors, and have historically moved through 
economic cycles with different timing. As such, it is difficult to estimate the potential impact of economic cycles and conditions 
or seasonality from year-to-year on our overall operating results. In addition, our results may be impacted by seasonality. The 
timing of widely observed holidays and vacation periods, particularly slow downs during the end-of-year holiday period, and 
availability of real estate agents and related service providers during these periods, could significantly affect our quarterly operating 
results during that period. If we are unable to adequately respond to economic, seasonal or cyclical conditions, our revenues, 
expenses and operating results may fluctuate from quarter to quarter. Our operating results, revenues and expenses may fluctuate 
for many reasons, including those described below and elsewhere in this Annual Report on Form 10-K: 

•  Rates of subscriber adoption and retention;
•  Timing of our sales conference or significant marketing events;
•  A slow-down during the end-of-year holiday period;
•  Changes in our pricing strategy and timing of changes;
•  The timing and success of new service introductions and enhancements; 
•  The shift of focus from, or phase out of services that overlap or are redundant with other services we offer;
•  The amount and timing of our operating expenses and capital expenditures;
•  Our ability to control expenses;
•  The amount and timing of non-cash stock-based charges;
•  Costs related to acquisitions of businesses or technologies or impairment charges associated with such investments and 

acquisitions;
•  Competition;
•  Changes or consolidation in the real estate industry; 
•  Our investments in geographic expansion and to increase coverage in existing markets; 
• 
• 
•  The development of our sales force; 
• 
• 
•  Changes in client budgets.  

Interest rate fluctuations; 
Successful execution of our expansion and integration plans; 

Foreign currency and exchange rate fluctuations; 
Inflation; and

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

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

The consent order, which is publicly available on the FTC's website at http://www.ftc.gov/, requires CoStar to maintain certain 
business practices that the FTC believes are pro-competitive.  For example, the consent order requires CoStar to maintain its 
customary practice of selling its products separately and on a market-by-market basis. It also requires CoStar to license its products 
to customers who have bought its competitors' products on a non-discriminatory basis. In addition, CoStar is required to maintain 
its customary licensing practices with respect to the length of its contracts, to allow customers with multi-year contracts to cancel 
with one year's advance notice, and to agree to reduce the cost of any litigation with customers by offering to arbitrate certain 
disputes. In the event that CoStar fails or is unable to comply with the terms of the consent order, CoStar could be subject to an 
enforcement proceeding that could result in substantial fines and/or injunctive relief. Further, the provisions of the consent order 
may result in unanticipated adverse effects on the combined company and, therefore, reduce our ability to realize the anticipated 
benefits of the merger. For example, the terms of the consent order that require us to continue to sell our products separately may 
prohibit us from combining or eliminating certain business lines, products or services that we believe would result in a long-term 
positive impact on our revenue and earnings. 

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

Changes in accounting and reporting policies or practices may affect our financial results or presentation of results, which 
may affect our stock price. Changes in accounting and reporting policies or practices could reduce our net income, which reductions 
may be independent of changes in our operations. These reductions in reported net income could cause our stock price to decline. For 
example, in 2006, we adopted authoritative guidance for stock compensation, which required us to expense the value of granted 
stock options.

Properties

Our headquarters is located at 1331 L Street, NW, in downtown Washington, DC, where we occupy approximately 149,500 
square feet of office space. Our lease for our headquarters 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, England, where 
we occupy approximately 7,000 square feet of office space. Our lease for this facility has a maximum term ending July 8, 2023, 
with early termination available at our option on July 9, 2018, with advance notice. This facility is used primarily by our International 
operating segment.

In addition to two downtown Washington, DC leased facilities (including our headquarters) and our London, England facility, 
our research operations are principally run out of leased spaces in San Diego, California; Columbia, Maryland; Atlanta, Georgia;  
and Glasgow, Scotland. Additionally, we lease office space in a variety of other metropolitan areas. These locations include, among 
others, the following: Boston, Massachusetts; Chicago, Illinois; Los Angeles, California; Norcross, Georgia; and San Francisco, 
California. 

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

Legal Proceedings

Currently, and from time to time, we are involved in litigation incidental to the conduct of our business. We are not a party 
to any lawsuit or proceeding that, in the opinion of our management based on consultations with legal counsel, is likely to have 
a material adverse effect on our financial position or results of operations.

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

CoStar Group, Inc. (the “Company” or “CoStar”) is the number one provider of information, analytics and online marketplaces 
to the commercial real estate industry in the United States (“U.S.”) and the 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; provide more information, analytics and marketing services than any of our competitors 
and believe that we generate more revenues than any of our commercial real estate information competitors. We created and 
compiled our standardized platform of information, analytics and online marketplace services where industry professionals and 
consumers of commercial real estate and apartments, and the related business communities, can continuously interact and facilitate 
transactions by efficiently accessing and exchanging accurate and standardized real estate-related information. 

We  have  five  flagship  brands  -  CoStar®,  LoopNet®,  Apartments.comTM,  BizBuySell®  and  LandsofAmericaTM.    Our 
subscription-based services consist primarily of information, analytics and online marketplace services offered over the Internet 
to commercial real estate industry and related professionals. Our subscription-based information services consist primarily of 
CoStar SuiteTM services. CoStar Suite is sold as a platform of service offerings consisting of CoStar Property Professional®, 
CoStar COMPS Professional® and CoStar Tenant® and through our mobile application, CoStarGo®. 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, data integration and industry news. We provide market research and 
analysis for commercial real estate investors and lenders via our CoStar Portfolio Strategy and CoStar Market Analytics service 
offerings; portfolio and debt analysis, management and reporting capabilities through our CoStar Investment Analysis and CoStar 
Risk Analytics service offerings; and, real estate and lease management solutions, including lease administration and abstraction 
services, through our CoStar Real Estate Manager service offerings.

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

Apartments.com  is  part  of  our  network  of  apartment  marketing  sites,  which  also  includes ApartmentFinder.comTM  and 
ApartmentHomeLiving.com. Our apartment marketing network of subscription-based services offers renters a searchable database 
of apartment listings and provides professional property management companies and landlords with an advertising destination. 
Through an exclusive agreement with Move, Inc., a subsidiary of News Corp., Apartments.com is also the exclusive third-party 
provider of apartment community listings across Move’s family of websites, which include realtor.com®, doorsteps.com and 
move.com.  

Our BizBuySell services, which includes BizQuest®, provide an online marketplace for operating businesses for sale. Our 

LandsofAmerica services, which includes LandAndFarm, provide an online marketplace for rural lands for sale.

Our service offerings span all commercial property types, including office, retail, industrial, multifamily, commercial land, 

mixed-use and hospitality.

Subscription-Based Services

Our subscription-based services consist primarily of information, analytics and online marketplace services offered over the 
Internet to commercial real estate industry and related professionals. Our services are typically distributed to our clients under 
subscription-based license agreements that renew automatically, a majority of which have a term of one year. Upon renewal, many 
of the subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations. To 
encourage clients to use our services regularly, we generally charge a fixed monthly amount for our subscription-based services 
rather than charging fees based on actual system usage or number of paid clicks. Depending on the type of service, contract rates 
are generally based on the number of sites, number of users, organization size, the client's business focus, geography, the number 
and types of services to which a client subscribes, the number of properties a client advertises and the prominence and placement 
of a client's advertised properties in the search results. Our subscription clients generally pay contract fees on a monthly basis, but 
in some cases may pay us on a quarterly or annual basis. 

Our subscription-based information services consist primarily of CoStar SuiteTM services. CoStar Suite is sold as a platform 
of service offerings consisting of CoStar Property Professional®, CoStar COMPS Professional® and CoStar Tenant® and through 
our mobile application, CoStarGo®. CoStar Suite is our primary service offering in our North America and International operating 
segments. 

As of December 31, 2014 and 2015, our annualized net new sales of subscription-based services on annual contracts were 
approximately $17.3 million and $29.2 million, respectively, calculated based on the annualized amount of change in our sales 
resulting from new annual subscription-based contracts or upsales on existing annual subscription-based contracts, less write 
downs and cancellations, for the period reported. We recognize subscription revenue on a straight-line basis over the life of the 
contract. Annual and quarterly advance payments result in deferred revenue, substantially reducing the working capital requirements 
generated by accounts receivable.

For the twelve months ended December 31, 2014 and 2015, our contract renewal rate for existing CoStar subscription-based 
services was approximately 92% and 90%, respectively, and therefore our cancellation rate for those services was approximately 
8% and 10%, respectively, for the same time periods. The recent decrease in our contract renewal rate is related to the execution 
of annual contracts by many of our LoopNet customers, who historically have not signed long term agreements and typically have 
a lower renewal rate than the rest of our subscription-based customers. 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. 

Apartment Rental Marketplaces

On April 1, 2014 (the “Closing Date”), we increased our presence in the multifamily vertical by acquiring from Classified 
Ventures,  LLC  (“CV”),  certain  assets  and  assuming  certain  liabilities,  in  each  case,  related  to  the Apartments.com  business 
(collectively referred to as “Apartments.com”), a national online apartment rentals resource for renters, property managers and 
owners. Apartments.com offers renters a database of apartment listings and provides professional property management companies 
and  landlords  an  advertising  destination.  Renters  can  conduct  personalized  searches  of  apartment  listings  and  view  video 
demonstrations  and  community  reviews  through  the Apartments.com  website  and  mobile  applications.  The Apartments.com 
network of rental websites also includes ApartmentHomeLiving.com, another national online apartment rentals resource.

Apartments.com draws on CoStar’s multifamily database, which contains detailed information on apartment properties. We 
designed the improved Apartments.com website, which was launched in February 2015, to meet renter preferences and demands, 
which we believe will drive traffic to the site and attract advertisers who prefer to advertise on heavily trafficked apartment websites. 
The  site  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, the site also offers innovative search tools such as the PolygonTM Search, which allows renters 
to specifically define the area in which they want to find an apartment, and Plan Commute tools, which allows renters to search 
property listings that meet their transportation needs.    

35

To further support our expansion into the multifamily vertical, on June 1, 2015, we acquired Network Communications, Inc. 
(“NCI”), including its Apartment Finder business (collectively referred to as “Apartment Finder”).  Apartment Finder provides 
lead  generation,  advertising,  and  Internet  marketing  solutions  to  property  managers  and  owners  through  its  main  service, 
ApartmentFinder.com. Similar to Apartments.com, we developed technology to allow ApartmentFinder.com to draw on CoStar’s 
multifamily database. In December 2015, we launched the new ApartmentFinder.com website to meet renter preferences and 
demands, which we believe will drive traffic to the site and attract advertisers who prefer to advertise on heavily trafficked apartment 
websites. We also have phased out print advertising from Apartment Finder and moved to an all-digital offering.

In 2015, we entered into an agreement to be the exclusive third party provider of apartment community listings on the websites 
owned and operated by News Corp. subsidiary Move, Inc.- realtor.com®, move.com, and doorsteps.com - with advertiser content 
from Apartments.com and ApartmentFinder.com.  Through this agreement, we are able to promote the apartment communities of 
our advertisers across six major apartment and real estate rental websites, increasing traffic across our network of apartment 
marketing websites, and in turn increasing the lead flow to our advertisers’ communities.

Similar to our other past acquisitions, we have been, and plan to continue, integrating, further developing and cross-selling 
the services offered by Apartments.com and ApartmentFinder.com and the other services we offer, including but not limited to 
CoStar  Market Analytics. We  have  incurred  and  plan  to  continue  to  incur  product  development  costs  to  improve  the  online 
Apartments.com and ApartmentFinder.com platforms. We have increased our sales and marketing expenses in order to support 
Apartments.com and to increase brand awareness. In conjunction with the launch of the improved Apartments.com website, we 
embarked on a wide-scale marketing campaign in 2015 to generate brand awareness and site traffic for Apartments.com. The 
marketing campaign featured television and radio advertising, online/digital advertising, social media and out-of-home ads and 
was reinforced by Search Engine Marketing.  We also increased our Search Engine Marketing to support Apartment Finder. In 
2016, we ran a Super Bowl ad to continue to generate brand awareness and site traffic for Apartments.com.  We expect to continue 
to invest in sales and marketing in 2016. As we continue to assess the success and effectiveness of our marketing campaign, we 
will also seek to determine the optimal level of marketing investment in the future.

Development and Expansion

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

The launch of the improved Apartments.com website in February 2015 and the new ApartmentFinder.com website in December 
2015 are examples of our software development efforts to improve existing services, introduce new services, integrate products 
and  services,  and  cross-sell  existing  services.  We  believe  the  improved  sites,  enhanced  search  capabilities,  availability  of 
information  regarding  real-time  vacancies,  and  our  continued  development  and  introduction  of  enhancements  to  our  online 
apartment rental marketplaces will attract more consumers, making these sites more attractive to property managers, which will 
increase our cross-selling opportunities. Our software development initiatives in 2015 included enhancing our new CoStar Lease 
Analysis® integrated workflow tool to provide users a simple way to produce understandable cash flows for leases, and to enhance 
other lease comparable services. We believe greater functionality makes our services valuable to an even broader audience and 
helps us increase sales of our services to brokers, banks, owners and institutional investors. We expect technology enhancements 
to drive continued revenue growth in 2016 and for the foreseeable future.

36

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. For example, 
we recently eliminated certain Apartment Finder services and phased out Apartment Finder print advertising and moved to an all-
digital offering. We expect a short-term reduction in revenues and associated costs resulting from the elimination of these Apartment 
Finder services. Additionally, we are working to integrate the backend systems of the LoopNet and CoStar databases, so that the 
two services will share a unified database of information in order to create efficiencies in operations and improved data for our 
customers. We also hope to increase the quantity and quality of the listing information available by enabling select brokers and 
other industry participants to load information directly into the integrated system, simultaneously reducing the time and costs 
associated  with  researching  and  maintaining  our  comprehensive  database  of  commercial  real  estate  information.  Further,  we 
continue to assess  whether to transition the LoopNet marketplace to a pure marketing site for commercial real estate where, 
eventually, all listings would be paid and users could search the site for free. If and when we implement such a shift, we will seek 
to convert LoopNet marketplace customers to higher value, more profitable annual subscription information services, which should 
increase revenues and earnings over time. However, we cannot predict with certainty the amount or timing of any reductions in 
revenues and earnings or subsequent increases in revenues and earnings, if any, resulting from any eliminations or phasing out of 
the LoopNet information services or any other service offering, if implemented.

Our revenues have increased as a result of revenue from acquired businesses and from cross-selling opportunities among the 
customers of CoStar and the acquired companies. We expect to continue to increase revenues as a result of such cross-selling 
opportunities. We may incur increased expenses in connection with any marketing and sales campaigns involving cross-selling 
opportunities and initiatives, and in connection with promotion of our new services and brands. 

We are expanding the geographic reach of our North America services. In 2014, we began offering our services in Toronto, 
Canada. Building on our experience in Toronto, we have expanded and are continuing to expand our research into additional 
Canadian cities. In the second quarter of 2015, we began offering services in Calgary and Vancouver and are currently researching 
commercial real estate in the Canadian cities of Ottawa and Edmonton. Further, on July 1, 2015, we expanded our International 
services  into  Madrid,  Spain  through  the  acquisition  of  the  assets  of  Belbex  Corporate,  S.L.,  a  small  commercial  real  estate 
information  provider  operating  in  Madrid. We  believe  that  our  integration  efforts  and  continued  investments  in  our  services, 
including 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 in North America and internationally. We plan to continue to invest in, evaluate and strategically position our sales force 
as the Company continues to develop and grow. We are also investing in our research capacity to support continued growth of our 
information and analytics offerings, to support Apartments.com and Apartment Finder, to expand into additional Canadian markets 
and to provide services in Madrid, Spain. While we believe investments we make in our business create a platform for growth, 
those investments may reduce our profitability and adversely affect our financial position.    

We intend to continue to assess the need for additional investments in our business, in addition to the investments discussed 
above in order to develop and distribute new services within our current platform or expand the reach of our current service 
offerings. Any future product development or expansion of services, combination and coordination of services or elimination of 
services  or  internal  expansion,  development  or  restructuring  efforts  could  reduce  our  profitability  and  increase  our  capital 
expenditures. Any new investments, changes to our service offerings or other unforeseen events could cause us to generate losses 
and negative cash flow from operations in the future. 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.

37

Financial Matters

Our financial reporting currency is the U.S. dollar. Changes in exchange rates can significantly affect our reported results and 
consolidated trends. We believe that our increasing diversification beyond the U.S. economy through our international businesses 
benefits our stockholders over the long term. We also believe it is important to evaluate our operating results before and after the 
effect of currency changes, as it may provide a more accurate comparison of our results of operations over historical periods. See 
Item 7A for details on the impact currency changes have on our results of operations. Currency exchange rate volatility may 
continue, which may impact (either positively or negatively) our reported financial results and consolidated trends and period-to-
period comparisons of our consolidated operations. 

We currently issue stock options and/or restricted stock to our officers, directors and employees, and as a result we record 
compensation expense in our consolidated statements of operations. The amount and timing of the compensation expense that we 
record depends on the amount and types of equity grants made. We plan to continue to use stock-based compensation for our 
officers, directors and employees, which may include, among other things, restricted stock, restricted stock units or stock option 
grants that typically will require us to record additional compensation expense in our consolidated statements of operations and 
reduce our net income. Grants of equity awards may vest over time or based on achievement of pre-approved performance conditions 
and market conditions.

In February 2014, the Compensation Committee of our Board of Directors approved grants of restricted common stock to 
our executive officers that vest based on our 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 December 31, 2016. In March 2015, 
the Compensation Committee of our Board of Directors approved grants of restricted common stock to our executive officers that 
vest based on our 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 December 31, 2017. These grants of restricted common stock are 
also subject to continuing employment requirements and a market condition based on total shareholder return (“TSR”). The actual 
number of shares that vest at the end of the respective three-year period is determined based on our achievement of the three-year 
performance goals described above, as well as our TSR relative to the Russell 1000 Index over the related three-year performance 
period. As of December 31, 2015, we reassessed the probability of achieving the performance and market conditions and determined 
that it was still probable that the performance and market conditions for the 2014 and 2015 performance-based restricted common 
stock awards would be met by their respective forfeiture dates. As a result, we recorded a total of approximately $1.1 million and 
$2.8 million of stock-based compensation expense related to the performance-based restricted common stock awards with a market 
condition for the years ended December 31, 2014 and 2015, respectively. We expect to record an estimated unrecognized stock-
based compensation expense related to the performance-based restricted common stock awards of approximately $5.3 million 
over the periods 2016, 2017 and 2018.

The Compensation Committee of our Board of Directors may grant additional performance-based equity awards in the future 

under the Company’s 2007 Stock Incentive Plan.

Property Developments

As in the past, we expect to continue to identify new facilities and consolidate existing facilities to better accommodate the 
changing  demands  of  our  business  and  employees. As  a  result,  we  may  incur  additional  lease  restructuring  charges  for  the 
abandonment of certain lease space and the impairment of leasehold improvements. 

Application of Critical Accounting Policies and Estimates

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.

38

Fair Value of Auction Rate Securities

Fair value is defined as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly 
transaction between market participants. There is a three-tier fair value hierarchy, which categorizes assets and liabilities by the 
inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active 
markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and 
Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own 
assumptions. Our Level 3 assets consist of auction rate securities (“ARS”), whose underlying assets are primarily student loan 
securities  supported  by  guarantees  from  the  Federal  Family  Education  Loan  Program  (“FFELP”)  of  the  U.S.  Department  of 
Education.

Our ARS investments are not currently actively trading and therefore do not currently have a readily determinable market 
value. The estimated fair value of the ARS no longer approximates par value. We have used a discounted cash flow model to 
determine the estimated fair value of our investment in ARS as of December 31, 2015. The assumptions used in preparing the 
discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of contractual cash flows, 
liquidity risk premiums, expected holding periods and default risk of the ARS. We update the discounted cash flow model on a 
quarterly basis to reflect any changes in the assumptions used in the model and settlements of ARS investments that occurred 
during the period.  

The only significant unobservable input in the discounted cash flow model is the discount rate. The discount rate used represents 
our estimate of the yield expected by a market participant from the ARS investments. The weighted average discount rate used in 
the discounted cash flow model as of December 31, 2014 and 2015 was approximately 4.1% and 4.7%, respectively. Selecting 
another discount rate within the range used in the discounted cash flow model would not result in a significant change to the fair 
value of the ARS. 

Based on this assessment of fair value, as of December 31, 2015, we determined there was a net decline in the fair value of 
our ARS investments of approximately $435,000. The decline was deemed to be a temporary impairment and recorded as an 
unrealized  loss  in  accumulated  other  comprehensive  loss  in  stockholders’  equity. If  the  issuers of  these ARS  are  unable  to 
successfully close future auctions and/or their credit ratings deteriorate, we may be required to record additional unrealized losses 
in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments, which 
would reduce our profitability and adversely affect our financial position.

We have not made any material changes in the accounting methodology used to determine the fair value of the ARS. We do 
not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used 
to calculate the fair value of the ARS as of December 31, 2015. However, if changes in these assumptions occur, and, should those 
changes be significant, we may be exposed to additional unrealized losses in accumulated other comprehensive loss or an other-
than-temporary impairment charge to earnings on these investments.

Stock-Based Compensation

We account for equity instruments issued in exchange for employee services using a fair-value based method and we recognize 
the fair value of such equity instruments as an expense in the consolidated statements of operations. We estimate the fair value of 
each option granted on the date of grant using the Black-Scholes option-pricing model, which requires us to estimate the dividend 
yield, expected volatility, risk-free interest rate and expected life of the stock option. For equity instruments that vest based on a 
market condition, we estimate the fair value of each equity instrument granted on the date of grant using a Monte-Carlo simulation 
model, which also requires us to estimate the dividend yield, expected volatility, risk-free interest rate and expected life of the 
equity instruments. These assumptions and the estimation of expected forfeitures are based on multiple factors, including historical 
employee behavior patterns of exercising options and post-employment termination behavior, expected future employee option 
exercise patterns, and the historical volatility of our stock price. For equity instruments that vest based on performance, we assess 
the probability of the achievement of the performance conditions at the end of each reporting period, or more frequently based 
upon the occurrence of events that may change the probability of whether the performance conditions would be met. If our initial 
estimates of the achievement of the performance conditions change, the related stock-based compensation expense and timing of 
recognition may fluctuate from period to period based on those estimates. If the performance conditions are not met, no stock-
based compensation expense will be recognized, and any previously recognized stock-based compensation expense will be reversed.  

We  do  not  expect  any  material  changes  in  the  near  term  to  the  underlying  assumptions  used  to  calculate  stock-based 
compensation expense for the year ended December 31, 2015. However, if changes in these assumptions occur, and, should those 
changes be significant, they could have a material impact on our stock-based compensation expense.

Business Combinations

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

Valuation of Long-Lived and Intangible Assets and Goodwill

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. We consider our operating segments, North America and International, as our reporting units under 
Financial Accounting Standards Board (“FASB”) authoritative guidance for consideration of potential impairment of goodwill.

To determine whether it is necessary to perform the two-step goodwill impairment test, 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. If we conclude 
that it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if we elect not to assess 
qualitative factors, then we perform the two-step process. The first step is to 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. 
Our assumptions regarding the future financial performance of the International reporting unit reflect our expectation as of October 
1, 2015, that revenues will continue to increase as a result of further penetration of our international subscription-based services, 
including into Madrid, Spain, and the successful cross-selling of our services to our customers in existing markets due to the 
release of our upgraded international platform and expansion of coverage of our international service offerings. 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 the second step of the process is performed to measure the impairment loss. 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, 2015, the date of our most recent 
impairment analysis, the estimated fair value of each of our reporting units substantially exceeded the carrying value of our reporting 
units. There have been no events or changes in circumstances since the date of our impairment analysis on October 1, 2015 that 
would indicate that the carrying value of each reporting unit may not be recoverable.

40

To determine whether it is necessary to perform the quantitative impairment test for indefinite-lived intangible assets, we may 
first assess qualitative factors to evaluate whether it is more likely than not that the fair value of the indefinite-lived intangible 
assets is less than the carrying amount. If we conclude that it is more likely than not that the fair value of the indefinite-lived 
intangible assets is less than the carrying amount or if we elect not to assess qualitative factors, then we perform a quantitative 
impairment test. We estimate the fair value of our existing indefinite-lived intangible assets using the relief from royalty method 
that includes significant assumptions and estimates including our discount rate, revenue growth rate and royalty rate. Assumptions 
about the discount rate are based on a weighted average cost of capital for comparable companies. Assumptions about the revenue 
growth rate are based on our forecasts, business plans and economic projections. Assumptions about the royalty rate are based on 
royalty agreements for comparable companies with similar intangible assets.

As of October 1, 2015, the date of our most recent annual impairment analysis, the estimated fair value of our indefinite-lived 
intangible assets substantially exceeded the carrying value. There have been no events or changes in circumstances since the date 
of our impairment analysis on October 1, 2015 that would indicate that the carrying value of the indefinite-lived intangible asset 
may not be recoverable.

During the first quarter of 2014, we finalized a branding initiative plan that included, among other things, re-branding some 
of the services provided by our wholly owned subsidiaries, in order to better organize, update, streamline and optimize our branding 
strategy. We launched the branding initiative externally in the second quarter of 2014. Following the external launch of the branding 
initiative, we ceased using certain of our trade names. We evaluated these assets for impairment during the first quarter of 2014 
and determined that the carrying value of trade names we ceased using exceeded the fair value. The adjusted carrying value of 
our trade name intangible assets associated with the branding initiative was amortized through the date of the external launch of 
the branding initiative and the fully amortized gross carrying amount was written off during the three months ended June 30, 2014. 

During the third quarter of 2014, we finalized and launched a separate marketing plan that included the re-branding of a 
service provided by another one of our wholly owned subsidiaries, in order to provide our customers with a more enhanced 
experience. Following the external launch of the branding initiative, we ceased using one of our trade names.  We evaluated the 
asset for impairment during the third quarter of 2014 and determined that the carrying value of the trade name that we ceased 
using exceeded the fair value. 

As a result of these branding and marketing plans during 2014, we recorded impairment charges of approximately $1.8 million 
in cost of revenues in the consolidated statements of operations within our North America operating segment for the year ended 
December 31, 2014.

In February 2015, as a result of our product development efforts, we launched the improved Apartments.com website with a 
cleaner look, information about actual rental availabilities, rents and other fees, and better search functionality. In conjunction 
with the launch, we ceased using the database technology acquired in the acquisition of Apartments.com. We evaluated the acquired 
database technology for impairment during the first quarter of 2015 and determined that the carrying value of the acquired database 
technology was impaired as we had ceased using the asset. 

In June 2015, following the June 1, 2015 acquisition of Apartment Finder, we decided to cease providing certain Apartment 
Finder  services. Additionally,  in  June  2015,  we  decided  to  cease  development  work  related  to  a  development  project  within 
Apartment Finder. We evaluated the acquired customer base and acquired database technology for impairment during the second 
quarter of 2015 and, based on that evaluation, determined that the customer base and database technology assets associated with 
the ceased services and development work were impaired as they were not expected to provide us with any economic benefit.

As a result of the launch of the improved Apartments.com website in 2015 and the decision to cease providing certain Apartment 
Finder services, we recorded an impairment charge of approximately $2.8 million, which was recorded in cost of revenues and 
general and administrative expense in the consolidated statements of operations within the Company's North America operating 
segment for the year ended December 31, 2015.

Accounting for Income Taxes

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

Non-GAAP Financial Measures

We prepare and publicly release quarterly unaudited financial statements prepared in accordance with 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 EBITDA, adjusted EBITDA, non-
GAAP net income and non-GAAP net income per diluted share (also referred to as “non-GAAP EPS”). EBITDA is our net income 
(loss)  before  interest,  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. Non-GAAP net income and non-GAAP net income per diluted share are similarly adjusted for stock-
based  compensation  expense,  acquisition-  and  integration-related  costs,  restructuring  costs,  settlement  and  impairment  costs 
incurred outside our ordinary course of business as well as purchase amortization and other related costs. We may disclose adjusted 
EBITDA, non-GAAP net income and non-GAAP net income per diluted share on a consolidated basis in our earnings releases, 
investor conference calls and filings with the Securities and Exchange Commission. The non-GAAP financial measures that we 
use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different 
non-GAAP financial measures in order to help our investors meaningfully evaluate and compare our results of operations to our 
previously reported results of operations or to those of other companies in our industry.

We view EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share as operating 
performance measures and as such we believe that the most directly comparable GAAP financial measure is net income (loss). In 
calculating EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share, we exclude from 
net income (loss) the financial items that we believe should be separately identified to provide additional analysis of the financial 
components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the 
material limitations on the use of these non-GAAP financial measures as a result of these exclusions. EBITDA, adjusted EBITDA, 
non-GAAP net income and non-GAAP net income per diluted share are not measurements of financial performance under GAAP 
and should not be considered as a measure of liquidity, as an alternative to net income (loss) or as an indicator of any other measure 
of performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on EBITDA, 
adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share as a substitute for any GAAP financial 
measure, including net income (loss). 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, non-GAAP net income and non-GAAP net income per diluted share.

42

EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share may be used by management 
to internally measure our operating and management performance and may be used by investors as supplemental financial measures 
to evaluate the performance of our business. We believe that these non-GAAP measures, when viewed with our GAAP results and 
the accompanying reconciliation, provide additional information that is useful to understand the factors and trends affecting our 
business. We have spent more than 28 years building our database of commercial real estate information and expanding our markets 
and services partially through acquisitions of complementary businesses. Due to the expansion of our information, analytics and 
online marketplace services, which has included acquisitions, our net income (loss) has included significant charges for purchase 
amortization,  depreciation  and  other  amortization,  acquisition-  and  integration-related  costs  and  restructuring  costs. Adjusted 
EBITDA, 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 purchase amortization, depreciation and other 
amortization, acquisition- and integration-related costs, restructuring costs and settlement and impairment costs incurred outside 
our ordinary course of business. We believe the disclosure of non-GAAP measures can help investors meaningfully evaluate and 
compare our performance from quarter to quarter and from year to year. We also believe the non-GAAP measures we disclose are 
measures of our ongoing operating performance because the isolation of non-cash charges, such as amortization and depreciation, 
and other items, such as interest, income taxes, stock-based compensation expenses, acquisition- and integration-related costs, 
restructuring costs 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, 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 the financial items that have been excluded from our net income (loss) to calculate EBITDA 

and the material limitations associated with using this non-GAAP financial measure as compared to net income (loss):

• 

• 

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

Purchase amortization 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 income we generate may be useful for investors to consider and may result in current cash inflows. 
However, we do not consider the amount of interest income to be a representative component of the day-to-day operating 
performance of our business.

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

• 

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

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

• 

Purchase  amortization  in  cost  of  revenues,  purchase  amortization  in  operating  expenses,  depreciation  and  other 
amortization, interest income, interest expense, and income tax expense as previously described above with respect to 
the calculation of EBITDA.

43

• 

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

•  The amount of material 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 financial items that have been excluded from our net income (loss) to calculate non-GAAP net income and non-GAAP 
net  income  per  diluted  share  are  purchase  amortization  and  other  related  costs,  stock-based  compensation,  acquisition-  and 
integration-related  costs,  restructuring  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 (loss). We subtract an assumed provision for 
income taxes to calculate non-GAAP net income. In 2013, 2014 and 2015, we assumed a 38% tax rate in order to approximate 
our long-term effective corporate tax rate.

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 (loss) per diluted share.

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

Comparison of Year Ended December 31, 2015 and Year Ended December 31, 2014 

Revenues. Revenues increased to $711.8 million in 2015, from $575.9 million in 2014. The $135.9 million increase was 
primarily attributable to increased revenue of approximately $83.8 million from Apartment Finder and Apartments.com as well 
as the further penetration of our subscription-based services and successful cross-selling of our services to our customers in existing 
markets, combined with continued high renewal rates.

Gross Margin. Gross margin increased to $522.9 million in 2015, from $419.0 million in 2014. The gross margin percentage 
increased to 73.5% in 2015, from 72.7% in 2014. The increase in the gross margin amount and percentage was principally due to 
an increase in revenue, partially offset by an increase in cost of revenues of $31.9 million. The increase in costs of revenues is 
primarily due to the additional cost of revenues from our June 1, 2015 acquisition of Apartment Finder.

Selling and Marketing Expenses. Selling and marketing expenses increased to $302.2 million in 2015, from $150.3 million 
in 2014, and increased as a percentage of revenues to 42.5% in 2015, from 26.1% in 2014. The increase in the amount and percentage 
of selling and marketing expenses was primarily due to a wide-scale marketing campaign that began during the first quarter of 
2015 and continued to run through the remainder of 2015 to generate brand awareness and site traffic for Apartments.com.

Software Development Expenses. Software development expenses increased to $65.8 million in 2015, from $55.4 million in 
2014, and decreased as a percentage of revenues to 9.2% in 2015, from 9.6% in 2014. The increase in the amount of software 
development expense was primarily due to an increase in personnel costs to support enhancements and upgrades to our services.

General and Administrative Expenses. General and administrative expenses increased to $115.5 million in 2015, from $103.9 
million in 2014, and decreased as a percentage of revenues to 16.2% in 2015 from 18.0% in 2014. The increase in the amount of 
general and administrative expenses was primarily due to additional general and administrative expenses of $16.3 million from 
Apartment Finder and Apartments.com.  These increases in general and administrative expenses were partially offset by loss 
contingencies and other legal costs related to litigation of approximately $3.4 million incurred during 2014 that did not occur 
during 2015, as well as a decrease in acquisition-related costs of approximately $479,000 in 2015 compared to 2014.

Purchase Amortization Expense. Purchase amortization expense decreased to approximately $27.9 million in 2015, from 
$28.4 million in 2014, and decreased as a percentage of revenue to 3.9% in 2015, compared to 4.9% in 2014. The decrease in the 
amount and percentage of purchase amortization expense was primarily due to a decrease in purchase amortization expense from 
LoopNet of $2.3 million due to the accelerated amortization of the LoopNet acquired customer base in 2014, partially offset by 
an increase in purchase amortization expenses of $2.0 million from Apartment Finder and Apartments.com in 2015.

Interest and Other Income. Interest and other income increased to approximately $537,000 in 2015 compared to approximately 
$516,000 in 2014. The increase was primarily due to our higher average cash and cash equivalent balance in 2015 resulting from 
the public equity offering we completed in June 2014.

Interest and Other Expense. Interest and other expense decreased to $9.4 million in 2015 compared to $10.5 million in 2014. 
The decrease was due to the decrease in interest expense resulting from a lower outstanding long-term debt balance during 2015, 
compared to 2014. 

Income Tax Expense, Net. Income tax expense, net decreased to $6.0 million in 2015 compared to $26.0 million in 2014. This 
decrease was primarily due to lower income before income taxes in 2015 as compared to 2014 as a result of our wide-scale 
marketing campaign that began during the first quarter of 2015 to generate brand awareness and site traffic for Apartments.com. 

Comparison of Business Segment Results for Year Ended December 31, 2015 and Year Ended December 31, 2014 

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 parts of Canada, and International, which includes parts of the U.K., 
Spain and France. Management relies on an internal management reporting process that provides revenue and operating segment 
EBITDA, which is our net income (loss) before interest, 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 our operating and management performance and to evaluate the performance 
of our 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 $686.6 million for the year ended December 31, 2015, compared 
to $552.1 million for the year ended December 31, 2014. This increase in North America revenues was primarily due to increased 
revenue of approximately $83.8 million from Apartment Finder and Apartments.com as well as the further penetration of our 
subscription-based services and successful cross-selling of our services to  our customers in existing markets, combined with 
continued high renewal rates. International revenues increased to $25.2 million for the year ended December 31, 2015, compared 
to $23.8 million for the year ended December 31, 2014. This increase was primarily due to further penetration of our subscription-
based information services resulting from sales of CoStar Suite. 

Segment EBITDA. North America EBITDA decreased to $87.1 million for the year ended December 31, 2015, compared to 
$148.9 million for the year ended December 31, 2014. The decrease in North America EBITDA was due primarily to our wide-
scale marketing campaign that began during the first quarter of 2015 to generate brand awareness and site traffic for Apartments.com. 
International EBITDA increased to $2.9 million for the year ended December 31, 2015, compared to $2.3 million for the year 
ended December 31, 2014. This increase in International EBITDA was primarily due to an increase in revenues. North America 
EBITDA includes an allocation of approximately $954,000 and $1.1 million for the years ended 2015 and 2014, respectively. This 
allocation represents costs incurred for International employees involved in development activities of our North America operating 
segment. International EBITDA includes a corporate allocation of approximately $256,000 and $261,000 for the years ended 
December 31, 2015 and 2014, respectively. This corporate allocation represents costs incurred for North America employees 
involved in management and expansion activities of our International operating segment. See the “Non-GAAP Financial Measures” 
section included in this Annual Report on Form 10-K for further details on the non-GAAP financial measures.

Comparison of Year Ended December 31, 2014 and Year Ended December 31, 2013 

Revenues. Revenues increased to $575.9 million in 2014, from $440.9 million in 2013. The $135.0 million increase was 
primarily attributable to increased revenue of approximately $76.8 million from our April 1, 2014 acquisition of Apartments.com 
as well as the further penetration of our subscription-based information services and successful cross-selling of our services to 
our customers in existing markets, combined with continued high renewal rates.

increased to 72.7% in 2014, from 70.7% in 2013. The increase in the gross margin amount and percentage was principally due to 
an increase in revenue partially offset by an increase in cost of revenues of $27.8 million primarily due to the additional cost of 
revenues from our April 1, 2014 acquisition of Apartments.com. 

Selling and Marketing Expenses. Selling and marketing expenses increased to $150.3 million in 2014, from $98.7 million in 
2013, and increased as a percentage of revenues to 26.1% in 2014, from 22.4% in 2013. The increase in the amount and percentage 
of selling and marketing expenses was primarily due to the additional selling and marketing expenses from our April 1, 2014 
acquisition of Apartments.com.

million in 2013, and decreased as a percentage of revenues to 18.0% in 2014 from 22.0% in 2013. The increase in the amount of

million in 2013, and increased as a percentage of revenue to 4.9% in 2014, compared to 3.4% in 2013. The increase in the amount 
and percentage of purchase amortization expense was due to additional purchase amortization expenses from our April 1, 2014 
acquisition of Apartments.com. 

Interest and Other Income. Interest and other income increased to approximately $516,000 in 2014 compared to approximately 
$326,000 in 2013. The increase was primarily due to our higher cash and cash equivalent balance in 2014 resulting from the public 
equity offering completed in June 2014. 

Interest and Other Expense. Interest and other expense increased to $10.5 million in 2014 compared to $6.9 million in 2013. 
The increase was due to the increase in interest expense resulting from a higher outstanding long-term debt balance during 2014, 
compared to 2013. 

Income Tax Expense, Net. Income tax expense, net increased to $26.0 million in 2014, from $17.8 million in 2013. This 

increase was primarily due to higher income before income taxes in 2014 as a result of our increased profitability.

Segment EBITDA. North America EBITDA increased to $148.9 million for the year ended December 31, 2014, compared to 
$97.3 million for the year ended December 31, 2013. The increase in North America EBITDA was due primarily to an increase 
in revenues in 2014 compared to 2013. International EBITDA increased to $2.3 million for the year ended December 31, 2014, 
compared to a loss of $3.1 million for the year ended December 31, 2013. This increase in International EBITDA was primarily 
due to an increase in revenue and a decrease in operating expenses. North America EBITDA includes an allocation of approximately 
$1.1 million and $800,000 for the years ended 2014 and 2013, respectively. This allocation represents costs incurred for International 
employees involved in development activities of our North America operating segment. International EBITDA includes a corporate 
allocation of approximately $300,000 and $400,000 for the years ended December 31, 2014 and 2013, respectively. This corporate

Apartments.com.  On April 1, 2014, we purchased from CV certain assets and assumed certain liabilities, in each case, related 

to Apartments.com, for $584.2 million in cash, after taking into account closing date net working capital adjustments.

Apartment Finder.  On June 1, 2015, we acquired 100% of the outstanding stock of NCI, including its Apartment Finder 

business, for $172.7 million in cash, after taking into account closing date net working capital adjustments.

48

 
 
 
 
Accounting Treatment. We have applied the acquisition method to account for the Apartments.com and Apartment Finder 
transactions, which requires that, among other things, assets acquired and liabilities assumed be recorded at their fair values as of 
the acquisition date. The purchase price for each acquisition was allocated to trade names, customer base, database technology, 
building photography, goodwill and various other asset and liability accounts. 

For Apartments.com, the acquired customer base for the acquisition consists of one distinct intangible asset, is composed of 
acquired customer contracts and the related customer relationships, and has an estimated useful life of ten years. The acquired 
database technology had an estimated useful life of one year due to our intent to replace the acquired database technology, which 
we did in February of 2015. The acquired trade names and other intangible assets have a weighted average estimated useful life 
of thirteen years. The acquired building photography has an estimated useful life of three years. Amortization of the acquired 
customer  base  is  recognized  on  an  accelerated  basis  related  to  the  expected  economic  benefit  of  the  intangible  asset,  while 
amortization of the acquired database technology, acquired building photography and acquired trade names and other intangible 
assets is recognized on a straight-line basis over their respective estimated useful lives. Goodwill recorded in connection with this 
acquisition is not amortized, but is subject to annual impairment tests. The results of operations of Apartments.com have been 
consolidated with those of the Company since the date of the acquisition. 

For Apartment Finder, the acquired customer base for the acquisition consisted of three distinct intangible assets, is composed 
of acquired customer contracts and the related customer relationships, and has a weighted average estimated useful life of ten 
years. The acquired database technology had an estimated useful life of five months due to our intent to replace the acquired 
database technology in 2015, which we did in December of 2015. The acquired trade names and other intangible assets have a 
weighted average estimated useful life of nine years. The acquired building photography had an estimated useful life of five 
months. Amortization of the acquired customer base is recognized on an accelerated basis related to the expected economic benefit 
of the intangible asset, while amortization of the acquired database technology, acquired building photography and acquired trade 
names and other intangible assets is recognized on a straight-line basis over their respective estimated useful lives. Goodwill 
recorded in connection with this acquisition is not amortized, but is subject to annual impairment tests. The results of operations 
of Apartment Finder have been consolidated with those of the Company since the date of the acquisition. 

See Note 3 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for further details 

on the acquisitions of Apartments.com and Apartment Finder. 

Liquidity and Capital Resources

Our principal sources of liquidity are cash, cash equivalents and debt from our term loan and revolving credit facility. Total 
cash and cash equivalents were $421.8 million at December 31, 2015 compared to cash and cash equivalents of $527.0 million at 
December 31, 2014. The decrease in cash and cash equivalents for the year ended December 31, 2015 was primarily due to net 
cash paid of $182.3 million for the acquisitions of Apartment Finder, the assets of Belbex Corporate, S.L., and certain assets related 
to the business operations of Apartment Finder's independent distributors.

Changes in cash and cash equivalents are dependent upon changes in, among other things, working capital items such as 
accounts receivable, accounts payable, various accrued expenses and deferred revenues, as well as changes in our capital structure 
due to stock option exercises and similar events.

Net cash provided by operating activities for the year ended December 31, 2015 was $131.2 million compared to $143.9 
million for the year ended December 31, 2014. The $12.7 million decrease in net cash provided by operating activities is primarily 
due  to  a  decrease  of  approximately  $15.7  million  from  net  income  plus  non-cash  items,  partially  offset  by  a  net  increase  of 
approximately $3.0 million in changes in operating assets and liabilities due to differences in timing of collection of receipts and 
payments of disbursements. 

Net cash used in investing activities for the year ended December 31, 2015 was $215.5 million compared to $606.0 million 
for the year ended December 31, 2014. This $390.5 million decrease in net cash used in investing activities in 2015 was primarily 
due to $584.2 million of cash used for the acquisition of Apartments.com on April 1, 2014, partially offset by $182.3 million of 
cash used for the acquisitions of Apartment Finder, the assets of Belbex Corporate, S.L., and certain assets related to the business 
operations of Apartment Finder's independent distributors during 2015.

49

Net cash used in financing activities was $20.5 million for the year ended December 31, 2015, compared to net cash provided 
by financing activities of $733.5 million for the year ended December 31, 2014. This $754.0 million change was primarily due to 
proceeds of $550.0 million received under the term loan facility and revolving credit facility on April 1, 2014 and the $529.4 
million in net proceeds from our public equity offering in June 2014, less the $148.8 million repayment of the term loan facility 
and revolving credit facility established under a credit agreement dated February 16, 2012 (the “2012 Credit Agreement”), $150.0 
million repayment of the revolving credit facility associated with the credit agreement by and among CoStar, as Borrower, CoStar 
Realty  Information,  Inc.,  as  Co-Borrower,  the  Lenders  from  time  to  time  party  thereto  and  JPMorgan  Chase  Bank,  N.A.,  as 
Administrative Agent (the “2014 Credit Agreement”) and the $10.0 million payment of debt issuance costs associated with the 
2014 Credit Agreement which did not occur during 2015.

Contractual Obligations. The following table summarizes our principal contractual obligations at December 31, 2015 and 

the effect such obligations are expected to have on our liquidity and cash flows in future periods (in thousands):

(1)Long-term debt obligations include scheduled principal payments and exclude interest payments, which are based on a 
variable rate of interest as defined in the Credit Agreement.

(2)Amounts do not include (i) contracts with terms of twelve months or less, or (ii) multi-year contracts that may be terminated 
by a third-party or us. Amounts do not include unrecognized tax benefits of $6.7 million due to uncertainty regarding the 
timing of future cash payments.

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. 

During  2015,  we  incurred  capital  expenditures  of  approximately  $35.1  million.  We  expect  to  make  aggregate  capital 
expenditures in 2016 of approximately $30.0 million to $35.0 million, primarily related to the build out of leased office space and 
investments in technology.

In conjunction with the launch of the improved Apartments.com website, we embarked on a wide-scale marketing campaign 
in 2015 to generate brand awareness and site traffic for Apartments.com. We expect to continue to invest in sales and marketing, 
including sales and marketing for Apartments.com and our other brands as we seek to grow the number of our subscribers and 
advertisers.

To date, we have grown in part by acquiring other companies and we may continue to make acquisitions. Our acquisitions 
may vary in size and could be material to our current operations. We may use cash, stock, debt or other means of funding to make 
these acquisitions.  

In consideration for the purchase of Apartment Finder, on June 1, 2015, we paid $172.7 million in cash, including an estimated 
$2.7 million in connection with a preliminary net working capital adjustment as of the closing date.  Pursuant to the terms of the 
agreement and plan of merger, the purchase price was increased by approximately $21,000 following the final determination of 
the net working capital of NCI as of the closing date, and this amount was paid to NCI in the third quarter of 2015. 

50

 
On April 1, 2014, we purchased Apartments.com from CV for a purchase price of $587.1 million, which was later reduced 
by approximately $2.9 million following the final determination of the net working capital of Apartments.com as of the Closing 
Date. On the Closing Date, we entered into the 2014 Credit Agreement. We funded the purchase price for Apartments.com at 
closing through a combination of cash on hand and the proceeds of the term loan facility and the initial borrowing under the 
revolving credit facility under the 2014 Credit Agreement. The 2014 Credit Agreement provides for a $400.0 million term loan 
facility and a $225.0 million revolving credit facility, each with a term of five years. The proceeds of the term loan facility and 
the initial borrowing of $150.0 million under the revolving credit facility on the Closing Date were also used to refinance the term 
loan facility and revolving credit facility established under the 2012 Credit Agreement, including related fees and expenses. The 
undrawn proceeds of the revolving credit facility are available for our working capital needs and other general corporate purposes. 
As of December 31, 2015, maturities of our borrowings under the 2014 Credit Agreement for each of the next four years ended 
December 31, 2016 to 2019, are expected to be $20.0 million, $35.0 million, $55.0 million and $255.0 million, respectively. During 
June 2014, we repaid the $150.0 million initial borrowing under the revolving credit facility.

The revolving credit facility includes a subfacility for swingline loans of up to $10.0 million, and up to $10.0 million of the 
revolving credit facility is available for the issuance of letters of credit. The term loan facility will amortize in quarterly installments 
in amounts resulting in an annual amortization of 5% during each of the first, second and third years, 10% during the fourth year 
and 15% during the fifth year after the Closing Date, with the remainder payable at final maturity. The loans under the 2014 Credit 
Agreement bear interest, at our option, either (i) during any interest period selected by us, at the London interbank offered rate 
for deposits in U.S. dollars with a maturity comparable to such interest period, adjusted for statutory reserves (“LIBOR”), plus an 
initial spread of 2.00% per annum, subject to adjustment based on our First Lien Secured Leverage Ratio (as defined in the 2014 
Credit Agreement), or (ii) at the greatest of (x) the prime rate from time to time announced by JPMorgan Chase Bank, N.A., (y) 
the federal funds effective rate plus 0.50% and (z) LIBOR for a one-month interest period plus 1.00%, plus an initial spread of 
1.00% per annum, subject to adjustment based on our First Lien Secured Leverage Ratio. If an event of default occurs under the 
2014 Credit Agreement, the interest rate on overdue amounts will increase by 2.00% per annum. The obligations under the 2014 
Credit Agreement are guaranteed by all of our material subsidiaries and are secured by a lien on substantially all of our assets and 
those of our material subsidiaries, in each case subject to certain exceptions, pursuant to security and guarantee documents entered 
into on the Closing Date.  

The 2014 Credit Agreement requires us to maintain (i) a First Lien Secured Leverage Ratio (as defined in the 2014 Credit 
Agreement) not exceeding 4.00 to 1.00 during each full fiscal quarter after the Closing Date through the three months ended March 
31, 2016, and 3.50 to 1.00 thereafter and (ii) after the incurrence of additional indebtedness under certain specified exceptions in 
the 2014 Credit Agreement, a Total Leverage Ratio (as defined in the 2014 Credit Agreement) not exceeding 5.00 to 1.00 during 
each full fiscal quarter after the Closing Date through the three months ended March 31, 2016, and 4.50 to 1.00 thereafter. The 
2014 Credit Agreement also includes other covenants, including covenants that, subject to certain exceptions, restrict our ability 
to (i) incur additional indebtedness, (ii) create, incur, assume or permit to exist any liens, (iii) enter into mergers, consolidations 
or  similar  transactions,  (iv)  make  investments  and  acquisitions,  (v)  make  certain  dispositions  of  assets,  (vi)  make  dividends, 
distributions and prepayments of certain indebtedness, and (vii) enter into certain transactions with affiliates. We were in compliance 
with the covenants in the 2014 Credit Agreement as of December 31, 2015.

In connection with obtaining the term loan facility and revolving credit facility pursuant to the 2014 Credit Agreement, we 
incurred  approximately  $10.1  million  in  debt  issuance  costs  as  of April  1,  2014. The  debt  issuance  costs  were  comprised  of 
approximately $9.7 million in underwriting fees and approximately $400,000 primarily related to legal fees associated with the 
debt issuance. Approximately $10.0 million of the fees associated with the refinancing, along with the unamortized debt issuance 
cost from the 2012 Credit Agreement, were capitalized and are amortized as interest expense over the term of the 2014 Credit 
Agreement using the effective interest method. 

As of December 31, 2014 and 2015, no amounts were outstanding under our revolving credit facilities. Total interest expense 
for our term loan facilities and revolving credit facilities was approximately $6.9 million, $10.5 million and $9.4 million for the 
years  ended  December 31,  2013,  2014  and  2015,  respectively.  Interest  expense  included  amortized  debt  issuance  costs  of 
approximately $3.0 million, $3.3 million and $3.3 million for the years ended December 31, 2013, 2014 and 2015, respectively. 
Total interest paid for the term loan facilities was approximately $4.3 million, $7.0 million and $6.1 million for the years ended 
December 31, 2013, 2014 and 2015, respectively. 

In 2012, we granted a total of 399,413 shares pursuant to performance-based restricted common stock awards with a forfeiture 
date of March 31, 2017. Upon vesting of these awards during the first quarter of 2014, consistent with minimum tax withholding 
requirements, a portion of the shares subject to the awards were remitted by the employees for payment of their individual income 
tax obligations. The shares remitted were canceled and we made a cash tax payment equivalent to the fair market value of the 
canceled shares of approximately $31.9 million during the three months ended March 31, 2014.

51

Based on current plans, we believe that our available cash combined with positive cash flow provided by operating activities 

should be sufficient to fund our operations for at least the next 12 months. 

As of December 31, 2015, we had $16.8 million par value of long-term investments in student loan ARS, which failed to 
settle at auctions. The majority of these investments are of high credit quality with AAA credit ratings and are primarily securities 
supported  by  guarantees  from  the  FFELP  of  the  U.S.  Department  of  Education. While  we  continue  to  earn  interest  on  these 
investments, the investments are not liquid in the short-term. In the event we need to immediately access these funds, we may 
have to sell these securities at an amount below par value. Based on our ability to access our cash and cash equivalents and our 
expected operating cash flows, we do not anticipate having to sell these investments below par value in order to operate our 
business in the foreseeable future.   

Recent Accounting Pronouncements

In May 2014, the FASB and International Accounting Standards Board (“IASB”) jointly issued a new revenue recognition 
standard that is designed to improve financial reporting by creating common recognition guidance for U.S. GAAP and International 
Financial Reporting Standards (“IFRS”). This guidance provides a more robust framework for addressing revenue issues, improves 
the  comparability  of  revenue  recognition  practices  across  industries,  provides  more  useful  information  to  users  of  financial 
statements through improved disclosure requirements and simplifies the presentation of financial statements. The core principle 
of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an 
amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This 
guidance permits the use of either a full retrospective method or a modified retrospective approach. The modified retrospective 
approach would be applied only to the most current period presented along with a cumulative-effect adjustment at the date of 
adoption. The original effective date of the new standard was for annual reporting periods beginning after December 15, 2016, 
including interim periods within that reporting period. In August 2015, the FASB issued an accounting standards update that defers 
by one year the effective date of this new revenue recognition standard.  As a result, the new standard will be effective for annual 
reporting periods beginning after December 15, 2017, although companies may adopt the standard as early as the original effective 
date. Early application prior to the original effective date is not permitted. We have not yet determined when we will adopt the 
standard or selected a transition method and are currently evaluating the impact this guidance will have on our financial statements. 

In April 2015, the FASB issued authoritative guidance to simplify the presentation of debt issuance costs. This guidance 
requires a company to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction 
from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for 
debt issuance costs are not affected by this guidance. In August 2015, the FASB issued an accounting standards update to address 
the presentation and subsequent measurement of debt issuance costs related to line-of-credit arrangements.  The guidance allows 
an entity to present debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortize the deferred 
debt  issuance  costs  ratably  over  the  term  of  the  line-of-credit  arrangement,  regardless  of  whether  there  are  any  outstanding 
borrowings  under  the  line-of-credit  arrangement. The April  2015  guidance  and  the August  2015  guidance  are  effective  on  a 
retrospective basis for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting 
period. Early application is permitted. We have elected to early adopt this guidance on a retrospective basis. This guidance did 
not have a material impact on the Company's results of operations for the years ended December 31, 2013, 2014 and 2015, but it 
did require changes to the presentation of the 2014 and 2015 consolidated balance sheets and the notes to the consolidated financial 
statements.  We  capitalized  debt  issuance  costs,  net  of  amortization,  of  approximately  $13.2  million  and  $9.9  million  as  of 
December 31, 2014 and December 31, 2015, respectively. These amounts are reflected in the consolidated balance sheets as a 
direct deduction from a combination of the current and long-term portion of debt, rather than as an asset, in accordance with the 
authoritative guidance. See Note 9 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-
K for further details on the presentation of debt issuance costs.

52

In November 2015, the FASB issued authoritative guidance to simplify the presentation of deferred income taxes. This guidance 
requires a company to present deferred income tax assets and liabilities as non-current in the balance sheet. The guidance requiring 
a tax-paying component of a company to offset deferred tax liabilities and assets and present the deferred taxes as a single amount 
is not affected by this guidance. This guidance is effective on either a prospective or retrospective basis for annual reporting periods 
beginning after December 15, 2016, including interim periods within that reporting period. Early application is permitted. We 
have elected to early adopt this guidance on a prospective basis and as a result, prior periods were not retrospectively adjusted.  
This guidance did not have a material impact on our results of operations for the year ended December 31, 2015. 

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

We  provide  information,  analytics  and  online  marketplace  services  to  the  commercial  real  estate  and  related  business 
community in the U.S. and parts of the U.K., Canada, Spain and France. Our functional currency for our operations in the U.K., 
Canada, Spain and France is the local currency. As such, fluctuations in the British Pound, Canadian dollar and Euro may have 
an impact on our business, results of operations and financial position. For the year ended December 31, 2015, revenue denominated 
in foreign currencies was approximately 4.1% of total revenue. For the year ended December 31, 2015, our revenue would have 
decreased by approximately $2.9 million if the U.S. dollar exchange rate used strengthened by 10%. In addition, we have assets 
and liabilities denominated in foreign currencies. A 10% strengthening of the U.S. dollar exchange rate against all currencies with 
which we have exposure at December 31, 2015 would have resulted in an increase of approximately $2.9 million in the carrying 
amount of net assets. For the year ended December 31, 2015, our revenue would have increased by approximately $2.9 million 
if  the  U.S.  dollar  exchange  rate  used  weakened  by  10%.  In  addition,  we  have  assets  and  liabilities  denominated  in  foreign 
currencies. A 10% weakening of the U.S. dollar exchange rate against all currencies with which we have exposure at December 31, 
2015 would have resulted in a decrease of approximately $2.9 million in the carrying amount of net assets. 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 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,  2015,  accumulated  other 
comprehensive loss included a loss from foreign currency translation adjustments of approximately $7.2 million.

We do not have material exposure to market risks associated with changes in interest rates related to cash equivalent securities 
held as of December 31, 2015. As of December 31, 2015, we had $421.8 million of cash and cash equivalents. If there is an increase 
or decrease in interest rates, there will be a corresponding increase or decrease in the amount of interest earned on our cash and 
cash equivalents. 

As of December 31, 2015, we had $365.0 million of long-term debt bearing interest at a variable rate of LIBOR plus 2.00%, 
subject to adjustment based on our First Lien Secured Leverage Ratio (as defined in the 2014 Credit Agreement). If there is an 
increase or decrease in interest rates, there will be a corresponding increase or decrease in the amount of interest expense on our 
long-term debt. Based on our outstanding borrowings as of December 31, 2015, an increase in the interest rate by 25 basis points 
would result in an increase of approximately $900,000 in interest expense annually. Based on our outstanding borrowings as of 
December 31, 2015, a decrease in the interest rate by 25 basis points would result in a decrease of approximately $900,000 in 
interest expense annually. Based on our ability to access our cash and cash equivalents, and our expected operating cash flows, 
we do not believe that increases or decreases in interest rates will impact our ability to operate our business in the foreseeable 
future.

Included  within  our  long-term  investments  are  investments  in  mostly AAA-rated  student  loan ARS. These  securities  are 
primarily securities supported by guarantees from the FFELP of the U.S. Department of Education. As of December 31, 2015, 
$16.8 million of our investments in auction rate securities failed to settle at auction. As a result, we may not be able to sell these 
investments at par value until a future auction on these investments is successful. In the event we need to immediately liquidate 
these investments, we may have to locate a buyer outside the auction process, who may be unwilling to purchase the investments 
at par, resulting in a loss. Based on an assessment of fair value of these investments in ARS as of December 31, 2015, we determined 
that there was a net decline in the fair value of our ARS investments of approximately $435,000, which was deemed to be a 
temporary impairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. If the 
issuers are unable to successfully close future auctions and/or their credit ratings deteriorate, we may be required to adjust the 
carrying value of these investments as a temporary impairment and recognize a greater unrealized loss in accumulated other 
comprehensive loss or as an other-than-temporary impairment charge to earnings. Based on our ability to access our cash and cash 
equivalents, and our expected operating cash flows, we do not anticipate having to sell these securities below par value in order 
to operate our business in the foreseeable future. See Notes 4 and 5 to the Notes to Consolidated Financial Statements included 
in this Annual Report on Form 10-K for further discussion.

53

We had approximately $1.5 billion in intangible assets as of December 31, 2015. As of December 31, 2015, 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.

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.

As of December 31, 2015, 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. 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.

 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, 2015 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.

54

Based  on  this  assessment,  management  did  not  identify  any  material  weakness  in  the  Company's  internal  control,  and 
management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2015.

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.

There have been no changes in our internal control over financial reporting during our most recent fiscal quarter that have 

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

On June 1, 2015, we completed the acquisition of Apartment Finder. As permitted by the Securities and Exchange Commission, 
we have elected to exclude the accounts receivable and revenue of Apartment Finder from our assessment of the effectiveness of 
our internal control over financial reporting as of December 31, 2015.  All other account balances were integrated into our control 
environment. The excluded financial position of Apartment Finder represented approximately 0.1% of our total assets at December 
31, 2015, and approximately 5.7% of our total revenue for the year ended December 31, 2015. We will include the internal controls 
of Apartment Finder accounts receivable and revenue in our assessment of the effectiveness of our internal control over financial 
reporting as of December 31, 2016.

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. as of December 31, 2015 and 2014, 
and the related consolidated statements of operations, comprehensive income (loss), stockholders' equity and cash flows for each 
of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedule listed in the 
Index  at  Item 15(a)(2).  These  financial  statements  and  schedule  are  the  responsibility  of  the  Company's  management.  Our 
responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by 
management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable 
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of CoStar Group, Inc. at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows 
for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.  
Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken 
as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
CoStar Group, Inc.'s internal control over financial reporting as of December 31, 2015, 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 25, 2016 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

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

We have audited CoStar Group, Inc.’s internal control over financial reporting as of December 31, 2015, 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). CoStar Group, Inc.’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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
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.

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.

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 Network Communications, Inc. related to accounts receivable and revenues, which are included in 2015 consolidated financial 
statements of CoStar Group, Inc. and constituted 0.1% of total assets as of December 31, 2015 and 5.7% of revenues 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 Network Communications, Inc.

In our opinion, CoStar Group, Inc. maintained, in all material respects, effective internal control over financial reporting as 

of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the consolidated balance sheets of CoStar Group, Inc. as of December 31, 2015 and 2014, and the related consolidated statements 
of operations, comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended 
December 31, 2015 of CoStar Group, Inc. and our report dated February 25, 2016 expressed an unqualified opinion thereon.

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  covering  the  United  States  (“U.S.”)  and  parts  of  the  United  Kingdom  (“U.K.”),  Canada,  Spain  and  France. The 
Company provides online marketplaces for commercial real estate, apartment rentals, lands for sale and businesses for sale. The 
Company operates within two operating segments, North America and International, 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 one year. 

2. 

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Basis of Presentation

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

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires 
management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying 
notes. On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to revenue recognition, 
allowance for doubtful accounts, useful lives of property and equipment and intangible assets, recoverability of long-lived assets 
and intangible assets with definite lives, goodwill, income taxes, fair value of equity instruments, fair value of auction rate securities, 
accounting for business combinations 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 revenue and 
expenses. Actual results could differ from these estimates. 

Reclassifications

Certain previously reported amounts in the consolidated balance sheets as of December 31, 2014 and Note 12 have been 
reclassified to conform to the Company's current presentation as a result of the retrospective application of the authoritative guidance 
to  simplify  the  presentation  of  debt  issuance  costs. Additionally,  certain  previously  reported  amounts  in  Note  10  have  been 
reclassified to conform to the Company's current presentation within the reconciliation of the Company’s provision for income 
taxes and the amount computed at the statutory federal income tax rate. 

Revenue Recognition

The Company primarily derives revenues by providing access to its proprietary database of commercial real estate information. 
The Company generally charges a fixed monthly amount for its subscription-based services. The Company and its subsidiaries' 
subscription-based services consist primarily of information, analytics and online marketplace services offered over the Internet 
to commercial real estate industry and related professionals. Subscription contract rates are based on the number of sites, number 
of users, organization size, the client’s business focus, geography, the number and types of services to which a client subscribes, 
the number of properties a client advertises and the prominence and placement of a client's advertised properties in the search 
results. A majority of the subscription-based license agreements have a term of one year and renew automatically. 

Revenue is recognized when (1) there is persuasive evidence of an arrangement, (2) the fee is fixed and determinable, (3) 

services have been rendered and payment has been contractually earned and (4) collectability is reasonably assured.

Revenues from subscription-based services are recognized on a straight-line basis over the term of the agreement. Deferred 
revenue results from advance cash receipts from customers or amounts billed in advance to customers from the sale of subscription 
licenses and is recognized over the term of the license agreement.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — (CONTINUED)

Cost of Revenues

Cost of revenues principally consists of salaries and related expenses 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. Additionally, 
cost of revenues includes the cost of data from third-party data sources, credit card and other transaction fees relating to processing 
customer transactions, which are expensed as incurred, and the amortization of acquired trade names and other intangible assets 
and database technology.

Foreign Currency Translation

The Company’s functional currency in its foreign locations is the local currency. Assets and liabilities are translated into U.S. 
dollars using the exchange rates as of the balance sheet dates. Revenues, expenses, gains and losses are translated at the average 
exchange  rates  in  effect  during  each  period.  Gains  and  losses  resulting  from  translation  are  included  in  accumulated  other 
comprehensive loss. Net gains or losses resulting from foreign currency exchange transactions are included in the consolidated 
statements of operations. There were no material gains or losses from foreign currency exchange transactions for the years ended 
December 31, 2013, 2014 and 2015.

Accumulated Other Comprehensive Loss

The components of accumulated other comprehensive loss were as follows (in thousands):

Foreign currency translation adjustment
Accumulated net unrealized loss on investments, net of tax

Total accumulated other comprehensive loss

There were no amounts reclassified out of accumulated other comprehensive loss to the consolidated statements of operations 

for the years ended December 31, 2013, 2014 and 2015, respectively.

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  $7.9  million,  $28.7  million  and  $132.1  million  for  the  years  ended 
December 31, 2013, 2014 and 2015, 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 it is 
anticipated that some or all of an asset may not be realized through future taxable earnings or implementation of tax planning 
strategies. Interest and penalties related to income tax matters are recognized in income tax expense.

Net Income (Loss) Per Share

Net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares 
outstanding during the period on a basic and diluted basis. The Company’s potentially dilutive securities include stock options and 
restricted stock. Diluted net income (loss) per share considers the impact of potentially dilutive securities except in periods in 
which there is a net loss, as the inclusion of the potentially dilutive common shares would have an anti-dilutive effect.

Stock-Based Compensation

Equity instruments issued in exchange for employee services 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.

Stock-based compensation expense is measured at the grant date of the stock-based awards that vest over set time periods 
based on their fair values, and is recognized on a straight-line basis as expense over the vesting periods of the awards, net of an 
estimated forfeiture rate. For equity instruments that vest based on performance, the Company assesses the probability of the 
achievement of the performance conditions at the end of each reporting period, or more frequently based upon the occurrence of 
events that may change the probability of whether the performance conditions would be met. If the Company's initial estimates 
of the achievement of the performance conditions change, the related stock-based compensation expense and timing of recognition 
may fluctuate from period to period based on those estimates. For equity instruments that vest based on a performance condition 
and a market condition, the Company estimates the fair value of each equity instrument granted on the date of grant using a Monte-
Carlo simulation model. This pricing model uses multiple simulations to evaluate the probability of achieving the market condition 
to calculate the fair value of the awards. Stock-based compensation expense is updated based on the expected achievement of the 
related performance conditions at the end of each reporting period. If the performance conditions are not met, no stock-based 
compensation expense will be recognized, and any previously recognized stock-based compensation expense will be reversed. 

In 2012, the Company granted performance-based restricted common stock awards that vest upon the Company’s achievement 
of $90.0 million of cumulative net income before interest, income taxes, depreciation and amortization (“EBITDA”) over a period 
of four consecutive calendar quarters if such performance is achieved by March 31, 2017, subject to certain approvals under the 
CoStar Group, Inc. 2007 Stock Incentive Plan. As of March 31, 2014, the Company had satisfied all performance conditions and 
the award recipients had satisfied all service conditions, and as a result, the restricted common stock granted under these awards 
vested. The Company recorded approximately $21.8 million, $2.2 million and $0 of stock-based compensation expense related to 
the 2012 performance-based restricted common stock awards for the years ended December 31, 2013, 2014 and 2015, respectively. 

In February 2014, the Compensation Committee of the Board of Directors of the Company approved grants of restricted 
common stock to the executive officers that vest based on the Company’s achievement of a three-year cumulative revenue goal 
established at the grant date, and are subject to forfeiture in the event the foregoing performance condition is not met by December 
31, 2016. In March 2015, the Compensation Committee of the Board of Directors of the Company approved grants of restricted 
common stock to the executive officers that vest based on the Company’s achievement of a three-year cumulative revenue goal 
established at the grant date, and are subject to forfeiture in the event the foregoing performance condition is not met by December 
31, 2017. These grants of restricted common stock are also subject to continuing employment requirements and a market condition 
based on total shareholder return (“TSR”). The actual number of shares that vest at the end of the respective three-year period is 
determined based on the Company’s achievement of the three-year performance goals described above, as well as its TSR relative 
to the Russell 1000 Index over the same three-year performance period. As of December 31, 2015, the Company reassessed the 
probability of achieving the performance and market conditions and determined that it was probable that the performance and 
market conditions for the 2014 and 2015 awards would be met by their respective forfeiture dates. As a result, the Company 
recorded a total of approximately $1.1 million and $2.8 million of stock-based compensation expense related to the performance-
based restricted common stock awards with a market condition for the years ended December 31, 2014 and 2015, respectively. 
The Company expects to record estimated stock-based compensation expense related to the performance-based restricted common 
stock awards of approximately $5.3 million over the periods 2016, 2017 and 2018.

Cash flows resulting from excess tax benefits are classified as part of cash flows from operating and financing activities. 
Excess tax benefits represent tax benefits for stock-based compensation in excess of the associated deferred tax asset for such 
equity compensation recorded as an increase to stockholders' equity. Net cash proceeds from the exercise of stock options and the 
purchase of shares under the Employee Stock Purchase Plan (“ESPP”) were approximately $18.1 million, $5.7 million and $7.4 
million for the years ended December 31, 2013, 2014 and 2015, respectively. The Company realized approximately $19.6 million, 
$28.4 million and $8.5 million of excess tax benefits from stock options exercised and restricted stock awards vested for the years 
ended December 31, 2013, 2014 and 2015, respectively.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash 

equivalents. Cash equivalents consist of money market fund investments and commercial paper. 

Investments

The Company determines the appropriate classification of debt and equity investments at the time of purchase and re-evaluates 
such designation as of each balance sheet date. The Company considers all of its investments to be available-for-sale. The Company's 
investments consist of long-term variable rate debt instruments with an auction reset feature, referred to as auction rate securities 
(“ARS”). Investments are carried at fair value.

Concentration of Credit Risk and Financial Instruments

The Company performs ongoing credit evaluations of its customers’ financial conditions and generally does not require that 
its customers’ obligations to the Company be secured. The Company maintains reserves for estimated inherent credit losses, and 
such losses have been within management’s expectations. The large size and widespread nature of the Company’s customer base 
and the Company’s lack of dependence on any individual customer 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, 
2013, 2014 and 2015. The carrying amount of the accounts receivable approximates the net realizable value. The carrying value 
of the accounts receivable, accounts payable, accrued expenses and long-term debt approximates fair value.

The Company holds cash at major financial institutions that often exceed Federal Deposit Insurance Corporation insured 
limits. The Company believes its credit risk is minimal. The Company manages its credit risk associated with cash concentrations 
by concentrating its cash deposits in high quality financial institutions and by periodically evaluating the credit quality of the 
primary financial institutions holding such deposits. 

Accounts Receivable, Net of Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount. Accounts receivable payment terms vary and amounts due from 
customers are stated in the financial statements net of an allowance for doubtful accounts. The allowance for doubtful accounts is 
based on the Company’s assessment of the collectability of customer accounts. The Company regularly reviews the allowance by 
considering factors such as historical experience, the aging of the balances, and current economic conditions that may affect a 
customer’s ability to pay.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — (CONTINUED)

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. Depreciation and amortization are calculated on a straight-line basis over the following estimated 
useful lives of the assets:

Leasehold improvements
Furniture and office equipment
Research vehicles
Computer hardware and software

Shorter of lease term or useful life
Five to ten years
Five to ten years
Two to five years

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

Goodwill and Intangible Assets

Goodwill represents the excess of costs over the fair value of assets of acquired businesses. Goodwill and intangible assets 
acquired  in  a  business  combination  and  determined  to  have  an  indefinite  useful  life  are  not  amortized,  but  instead  tested  for 
impairment at least annually by each reporting unit. The Company’s operating segments, North America and International, are the 
reporting units tested for potential impairment. To determine whether it is necessary to perform the two-step goodwill impairment 
test, the Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting 
unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit 
is less than its carrying amount or if the Company elects not to assess qualitative factors, then the Company performs the two-step 
process. The first step is to determine the fair value of each reporting unit. The estimate of the fair value of each reporting unit is 
based on a projected discounted cash flow model that includes significant assumptions and estimates including the Company's 
discount rate, growth rate and future financial performance. Assumptions about the discount rate are based on a weighted average 
cost of capital for comparable companies. Assumptions about the growth rate and future financial performance of a reporting unit 
are based on the Company's forecasts, business plans, economic projections and anticipated future cash flows. The fair value of 
each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds 
the fair value, then the second step of the process is performed to measure the impairment loss. 

To determine whether it is necessary to perform the quantitative impairment test for indefinite-lived intangible assets, the 
Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of the indefinite-lived 
intangible assets is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of 
the indefinite-lived intangible assets is less than the carrying amount or if the Company elects not to assess qualitative factors, 
then the Company performs a quantitative impairment test. The Company estimates the fair value of its existing indefinite-lived 
intangible assets using the relief from royalty method that includes significant assumptions and estimates including the Company's 
discount rate, revenue growth rate and royalty rate. Assumptions about the discount rate are based on a weighted average cost of 
capital for comparable companies. Assumptions about the revenue growth rate are based on the Company's forecasts, business 
plans and economic projections. Assumptions about the royalty rate are based on royalty agreements for comparable companies 
with similar intangible assets.

Intangible assets with estimable useful lives that arose from acquisitions on or after July 1, 2001 are amortized over their 
respective estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the 
intangible assets are consumed or otherwise used up. Intangible assets are reviewed for impairment at least annually, and more 
frequently whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Goodwill and Intangible Assets — (Continued)

Acquired  database  technology,  customer  base  and  trade  names  and  other  intangible  assets  are  related  to  the  Company’s 
acquisitions (see Notes 3, 7 and 8).  Acquired database technology is amortized on a straight-line basis over periods ranging from 
five months to eight years. With the exception of the acquired trade name recorded in connection with the acquisition of LoopNet, 
acquired trade names and other intangible assets are amortized on a straight-line basis over periods ranging from seven months to 
fifteen years. The acquired trade name recorded in connection with the LoopNet acquisition has an indefinite estimated useful life 
and is not amortized, but is subject to annual impairment tests. Acquired intangible assets characterized as customer base consists 
of acquired customer contracts and the related customer relationships and are amortized over periods ranging from ten years to 
thirteen years. Acquired customer bases are typically amortized on an accelerated basis related to the expected economic benefit 
of the intangible asset. The cost of capitalized building photography is amortized on a straight-line basis over periods ranging from 
five months to five years.

Long-Lived Assets

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

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

Debt Issuance Costs

Costs incurred in connection with the issuance of long-term debt are capitalized and amortized as interest expense over the 
term of the related debt using the effective interest method. These amounts are reflected in the consolidated balance sheets as a 
direct deduction from a combination of the current and long-term portion of debt. Upon a refinancing, 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 
using the effective interest method. The Company had capitalized debt issuance costs, net of amortization, of approximately $13.2 
million and $9.9 million as of December 31, 2014 and 2015, respectively. The debt issuance costs are associated with the financing 
commitment received from JPMorgan Chase Bank, N.A. (“J.P. Morgan Bank”) on April 27, 2011, the subsequent term loan facility 
and revolving credit facility established under a credit agreement dated February 16, 2012 (the “2012 Credit Agreement”), the 
financing commitment received from J.P. Morgan Bank, Bank of America, N.A., SunTrust Bank and Wells Fargo Bank, National 
Association on February 28, 2014, and the subsequent term loan facility and revolving credit facility established under a credit 
agreement dated April 1, 2014 (the “2014 Credit Agreement”). See Note 9 for additional information regarding the term loan 
facility and revolving credit facility. The Company amortized debt issuance costs of approximately $3.0 million, $3.3 million and 
$3.3 million for the years ended December 31, 2013, 2014 and 2015, respectively.

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 excess of the fair value of purchase consideration over the fair values of these 
identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and 
assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are 
not limited to, future expected cash flows from acquired customer bases, acquired database technology, and acquired trade names 
from a market participant's perspective, useful lives and discount rates. During the measurement period, the Company may record 
adjustments  to  the  assets  acquired  and  liabilities  assumed.  Upon  the  conclusion  of  the  measurement  period,  any  subsequent 
adjustments are recorded to earnings. See Note 3 for additional information regarding the Company's recent business combinations.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board (“IASB”) 
jointly issued a new revenue recognition standard that is designed to improve financial reporting by creating common recognition 
guidance  for  U.S.  GAAP  and  International  Financial  Reporting  Standards  (“IFRS”).  This  guidance  provides  a  more  robust 
framework for addressing revenue issues, improves the comparability of revenue recognition practices across industries, provides 
more useful information to users of financial statements through improved disclosure requirements and simplifies the presentation 
of financial statements. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of 
promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in 
exchange for those goods or services. This guidance permits the use of either a full retrospective method or a modified retrospective 
approach.  The modified retrospective approach would be applied only to the most current period presented along with a cumulative-
effect adjustment at the date of adoption. The original effective date of the new standard was for annual reporting periods beginning 
after December 15, 2016, including interim periods within that reporting period. In August 2015, the FASB issued an accounting 
standards update that defers by one year the effective date of this new revenue recognition standard.  As a result, the new standard 
will be effective for annual reporting periods beginning after December 15, 2017, although companies may adopt the standard as 
early as the original effective date. Early application prior to the original effective date is not permitted.  The Company has not 
yet determined when it will adopt the standard or selected a transition method and is currently evaluating the impact this guidance 
will have on its financial statements. 

In April 2015, the FASB issued authoritative guidance to simplify the presentation of debt issuance costs. This guidance 
requires a company to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction 
from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt 
issuance costs are not affected by this guidance. In August 2015, the FASB issued an accounting standards update to address the 
presentation and subsequent measurement of debt issuance costs related to line-of-credit arrangements. The guidance allows an 
entity to present debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortize the deferred debt 
issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings 
under the line-of-credit arrangement. The April 2015 guidance and the August 2015 guidance are effective on a retrospective basis 
for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early 
application is permitted. The Company has elected to early adopt this guidance on a retrospective basis. This guidance did not 
have a material impact on the Company's results of operations for the years ended December 31, 2013, 2014 and 2015, but it did 
require changes to the presentation of the 2014 and 2015 consolidated balance sheets and the notes to the consolidated financial 
statements. The Company had capitalized debt issuance costs, net of amortization, of approximately $13.2 million and $9.9 million 
as of December 31, 2014 and December 31, 2015, respectively. These amounts are reflected in the consolidated balance sheets as 
a direct deduction from a combination of the current and long-term portion of debt, rather than as an asset, in accordance with the 
authoritative guidance. See Note 9 for further details on the presentation of debt issuance costs.

In November 2015, the FASB issued authoritative guidance to simplify the presentation of deferred income taxes. This guidance 
requires a company to present deferred income tax assets and liabilities as non-current in the balance sheets. The guidance requiring 
a tax-paying component of a company to offset deferred tax liabilities and assets and present the deferred taxes as a single amount 
is not affected by this guidance. This guidance is effective on either a prospective or retrospective basis for annual reporting periods 
beginning after December 15, 2016, including interim periods within that reporting period. Early application is permitted. The 
Company has elected to early adopt this guidance on a prospective basis and as a result, prior periods were not retrospectively 
adjusted. This guidance did not have a material impact on the Company's results of operations for the year ended December 31, 
2015.

ACQUISITIONS

Apartments.com

On February 28, 2014, the Company and Classified Ventures, LLC (“CV”) entered into an Asset Purchase Agreement (the 
“Asset Purchase Agreement”). Pursuant to the Asset Purchase Agreement, on April 1, 2014 (the “Closing Date”), the Company 
purchased  from  CV  certain  assets  and  assumed  certain  liabilities,  in  each  case,  related  to  the Apartments.comTM  business 
(collectively referred to as “Apartments.com”). Apartments.com is a national online apartment rentals resource for renters, property 
managers and owners. Apartments.com offers renters a searchable database of apartment listings and provides professional property 
management companies and landlords with an advertising destination. Renters can conduct personalized searches of apartment 
listings and view video demonstrations and community reviews through the Apartments.com website and mobile applications. 
The Apartments.com network of rental websites also includes ApartmentHomeLiving.com, another national online apartment 
rentals resource. The acquisition increased the Company's presence in the multifamily vertical. 

In consideration for the purchase of Apartments.com, on April 1, 2014, the Company paid $587.1 million in cash, including 
an estimated $2.1 million in connection with a preliminary net working capital adjustment as of the Closing Date. Pursuant to the 
terms  of  the Asset  Purchase Agreement,  the  purchase  price  was  reduced  by  approximately  $2.9  million  following  the  final 
determination of the net working capital of Apartments.com as of the Closing Date, and CV paid the Company $2.9 million on 
July 9, 2014. 

The Company applied the acquisition method to account for the Apartments.com transaction, which requires that, among 
other things, assets acquired and liabilities assumed be recorded at their fair values as of the acquisition date. The following table 
summarizes the amounts for acquired assets and liabilities recorded at their fair values as of the acquisition date (in thousands):

The net assets of Apartments.com were recorded at their estimated fair value. In valuing acquired assets and liabilities, fair 
value  estimates  were  based  on,  but  were  not  limited  to,  future  expected  cash  flows,  market  rate  assumptions  for  contractual 
obligations, and appropriate discount rates.

The acquired customer base for the acquisition consists of one distinct intangible asset, is composed of acquired customer 
contracts and the related customer relationships, and has an estimated useful life of ten years. The acquired database technology 
had an estimated useful life of one year due to the Company's intent to replace the acquired database technology, which it did in 
February of 2015. The acquired trade names and other intangible assets have a weighted average estimated useful life of thirteen 
years. The acquired building photography has an estimated useful life of three years. Amortization of the acquired customer base 
is recognized on an accelerated basis related to the expected economic benefit of the intangible asset, while amortization of the 
acquired database technology, acquired building photography and acquired trade names and other intangible assets is recognized 
on a straight-line basis over their respective estimated useful lives. Goodwill recorded in connection with this acquisition is not 
amortized, but is subject to annual impairment tests. The $421.7 million of goodwill recorded as part of the acquisition is associated 
with the Company's North America operating segment and the Company expects the entire amount of goodwill to be deductible 
for income tax purposes in future periods. 

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future 
economic  benefits  arising  from  other  assets  acquired  that  could  not  be  individually  identified  and  separately  recognized. 
Specifically,  the  goodwill  recorded  as  part  of  the Apartments.com  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 Apartments.com's operations; 
and (ii) any intangible assets that do not qualify for separate recognition, such as the assembled workforce.

As a result of the acquisition of Apartments.com, the Company recorded approximately $1.4 million in acquisition-related 
costs for the year ended December 31, 2014. These costs include expenses directly related to acquiring Apartments.com, are 
expensed as incurred and are recorded in general and administrative expense. The Company did not record any acquisition-related 
costs as a result of the acquisition of Apartments.com for the years ended December 31, 2013 and 2015.

Apartment Finder

Pursuant to the definitive agreement and plan of merger with Network Communications, Inc. (“NCI”) dated April 27, 2015 
(the “Merger Agreement”), on June 1, 2015, the Company acquired 100% of the outstanding stock of NCI and the related Apartment 
Finder business (collectively referred to as “Apartment Finder”) from the former stockholders of NCI. Apartment Finder provides 
lead  generation,  advertising  and  Internet  marketing  solutions  to  property  managers  and  owners  through  its  main  service, 
ApartmentFinder.comTM. The acquisition furthered the Company's expansion into the multifamily vertical.

In consideration for the purchase of Apartment Finder, on June 1, 2015, the Company paid $172.7 million in cash, including 
an estimated $2.7 million in connection with a preliminary adjustment for net working capital as of the closing date. Pursuant to 
the terms of the Merger Agreement, the purchase price was increased by approximately $21,000 following the final determination 
of the net working capital of NCI as of the closing date, and this amount was paid to NCI in the third quarter of 2015. 

The Company applied the acquisition method to account for the Apartment Finder transaction, which requires that, among 
other things, assets acquired and liabilities assumed be recorded at their fair values as of the acquisition date. The following table

INVESTMENTS

The Company determines the appropriate classification of debt and equity investments at the time of purchase and re-evaluates 
such designation as of each balance sheet date. The Company considers all of its investments to be available-for-sale. The Company's 
investments consist of long-term variable rate debt instruments with an auction reset feature, referred to as ARS. Investments are 
carried at fair value.

The Company had no realized gains on its investments for the years ended December 31, 2013, 2014 and 2015, respectively. The 
Company had no realized losses on its investments for the years ended December 31, 2013, 2014 and 2015, respectively. Realized 
gains and losses from the sale of available-for-sale securities are determined on a specific-identification basis.

Changes in unrealized holding gains and losses, net of the related tax effect, on available-for-sale securities are excluded from 
earnings and are reported as a separate component of accumulated other comprehensive loss in stockholders’ equity until realized. 
A decline in market value of any available-for-sale security 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.

INVESTMENTS — (CONTINUED)

The  unrealized  losses  on  the  Company’s  investments  as  of  December 31,  2014  and  2015  were  generated primarily  from 
changes in interest rates and ARS that failed to settle at auction, due to adverse conditions in the global credit markets. The losses 
are considered temporary, as the contractual terms of these investments do not permit the issuer to settle the security at a price less 
than the amortized cost of the investment. Because the Company does not intend to sell these instruments and it is not more likely 
than not that the Company will be required to sell these instruments prior to anticipated recovery, which may be at maturity, the 
Company does not consider these investments to be other-than-temporarily impaired as of December 31, 2014 and 2015. See Note 
5 for further discussion of the fair value of the Company’s financial assets.

FAIR VALUE

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

The  following  table  represents  the  Company's  fair  value  hierarchy  for  its  financial  assets  (cash,  cash  equivalents  and 

investments) measured at fair value on a recurring basis as of December 31, 2015 (in thousands):

The Company’s Level 3 assets consist of ARS, whose underlying assets are primarily student loan securities supported by

ARS  are  variable  rate  debt  instruments  whose  interest  rates  are  reset  approximately  every  28  days. The  majority  of  the 

underlying securities have contractual maturities greater than twenty years. The ARS are recorded at fair value.

As of December 31, 2015, the Company held ARS with $16.8 million par value, all of which failed to settle at auction. The 
majority of these investments are of high credit quality with AAA credit ratings and are primarily student loan securities supported 
by guarantees from the FFELP of the U.S. Department of Education. The Company may not be able to liquidate and fully recover 
the carrying value of the ARS in the near term. As a result, these securities are classified as long-term investments in the Company’s 
consolidated balance sheet as of December 31, 2015. 

While the Company continues to earn interest on its ARS investments at the contractual rate, these investments are not currently 
actively trading and therefore do not currently have a readily determinable market value. The estimated fair value of the ARS no 
longer approximates par value. The Company used a discounted cash flow model to determine the estimated fair value of its 
investment in ARS as of December 31, 2015. The assumptions used in preparing the discounted cash flow model include estimates 
for interest rates, credit spreads, timing and amount of contractual cash flows, liquidity risk premiums, expected holding periods 
and default risk. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the assumptions 
used in the model and settlements of ARS investments that occurred during the period. 

The only significant unobservable input in the discounted cash flow model is the discount rate. The discount rate used represents 
the Company's estimate of the yield expected by a market participant from the ARS investments. The weighted average discount 
rate used in the discounted cash flow model as of December 31, 2014 and 2015 was approximately 4.1% and 4.7%, respectively. 
Selecting another discount rate within the range used in the discounted cash flow model would not result in a significant change 
to the fair value of the ARS.

FAIR VALUE — (CONTINUED)

Based on this assessment of fair value, as of December 31, 2015, the Company determined there was a net decline in the fair 
value of its ARS investments of approximately $435,000. The decline was deemed to be a temporary impairment and recorded as 
an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. In addition, while a majority of the ARS are 
currently  rated AAA,  if  the  issuers  are  unable  to  successfully  close  future  auctions  and/or  their  credit  ratings  deteriorate,  the 
Company  may  be  required  to  record  additional  unrealized  losses  in  accumulated  other  comprehensive  loss  or  an  other-than-
temporary impairment charge to earnings on these investments.

(1) The  weighted-average  amortization  period  for  acquired  trade  names  excludes  $48.7  million  for  acquired  trade  names 
recorded in connection with the LoopNet acquisition on April 30, 2012, which amount is not amortized, but is subject to 
annual impairment tests. 

Amortization expense for intangible assets was approximately $27.6 million, $55.3 million and $58.6 million for the years 

ended December 31, 2013, 2014 and 2015, respectively.

In the aggregate, the Company expects amortization for intangible assets existing as of December 31, 2015 for future periods 
to be approximately $43.0 million, $28.5 million, $20.3 million, $17.4 million and $15.8 million for the years ending December 
31, 2016, 2017, 2018, 2019 and 2020, respectively.

During the fourth quarter of 2015, the Company completed the annual impairment test of the acquired trade name recorded 

in connection with the LoopNet acquisition and concluded that this indefinite-lived intangible asset was not impaired.

During the first quarter of 2014, the Company finalized a branding initiative plan that included, among other things, re-
branding some of the services provided by its wholly owned subsidiaries, in order to better organize, update, streamline and 
optimize the Company’s branding strategy. The Company launched the branding initiative externally in the second quarter of 2014. 
Following the external launch of the branding initiative, the Company ceased using certain of its trade names. The Company 
evaluated these assets for impairment during the first quarter of 2014 and determined that the carrying value of trade names that 
the Company ceased using exceeded the fair value. The adjusted carrying value of the Company's trade name intangible assets 
associated with the branding initiative was amortized through the date of the external launch of the branding initiative and the 
fully amortized gross carrying amount was written off during the three months ended June 30, 2014.

INTANGIBLE ASSETS — (CONTINUED)

During the third quarter of 2014, the Company finalized and launched a separate marketing plan that included the re-branding 
of a service provided by another one of its wholly owned subsidiaries, in order to provide its customers with a more enhanced 
experience. Following the external launch of the marketing plan, the Company ceased using one of its trade names.  The Company 
evaluated the asset for impairment during the third quarter of 2014 and determined that the carrying value of the trade name that 
the Company ceased using exceeded the fair value. 

As a result of these branding and marketing plans, during 2014, the Company recorded impairment charges of approximately 
$1.8 million in cost of revenues in the consolidated statements of operations within its North America operating segment for the 
year ended December 31, 2014.

In February 2015, as a result of the Company's product development efforts, it launched an improved  Apartments.com website 
with a cleaner look, information about actual rental availabilities, rents and other fees, and better search functionality. In conjunction 
with the launch, the Company ceased using the database technology acquired in the acquisition of Apartments.com. The Company 
evaluated the acquired database technology for impairment during the first quarter of 2015 and determined that the carrying value 
of the acquired database technology was impaired as the Company had ceased using the asset. The Company recorded an impairment 
charge of approximately $1.4 million in cost of revenues in the consolidated statements of operations within the Company's North 
America operating segment for the year ended December 31, 2015. 

In June 2015, following the June 1, 2015 acquisition of Apartment Finder, the Company decided to cease providing certain 
Apartment Finder services. Additionally, in June 2015, the Company decided to cease development work related to a development 
project  within Apartment  Finder. The  Company  evaluated  the  acquired  customer  base  and  acquired  database  technology  for 
impairment during the second quarter of 2015 and, based on that evaluation, determined that the customer base and database 
technology assets associated with the ceased services and development work were impaired as they were not expected to provide 
any economic benefit to the Company. The Company recorded an impairment charge of approximately $1.4 million, most of which 
was recorded in general and administrative expenses in the consolidated statements of operations within the Company's North 
America operating segment for the year ended December 31, 2015.

LONG-TERM DEBT 

On April 1, 2014, the Company entered into the 2014 Credit Agreement by and among the Company, as Borrower, CoStar 
Realty  Information,  Inc.,  as  Co-Borrower,  the  Lenders  from  time  to  time  party  thereto  and  JPMorgan  Chase  Bank,  N.A.,  as 
Administrative Agent. The 2014 Credit Agreement provides for a $400.0 million term loan facility and a $225.0 million revolving 
credit facility, each with a term of five years. The proceeds of the term loan facility and the initial borrowing of $150.0 million 
under the revolving credit facility on the Closing Date were used to refinance the 2012 Credit Agreement, including related fees 
and expenses, and to pay a portion of the consideration and transaction costs related to the acquisition of Apartments.com. The 
undrawn proceeds of the revolving credit facility are available for the Company's working capital needs and other general corporate 
purposes. During June 2014, the Company repaid the $150.0 million initial borrowing under the revolving credit facility. The 
carrying value of the term loan facility approximates fair value and can be estimated through Level 3 unobservable inputs using 
a valuation technique based on expected cash flows discounted using the current credit-adjusted risk-free rate, which approximates 
the rate of interest on the term loan facility at origination.

Effective April 1, 2014, the Company terminated the 2012 Credit Agreement and repaid all amounts outstanding thereunder, 
which amounts totaled $148.8 million. The Company evaluated the execution of the 2014 Credit Agreement and termination of 
the 2012 Credit Agreement and determined that the transactions did not qualify as an extinguishment of debt because the change 
in the present value of future cash flows between the initial term loan facility under the 2012 Credit Agreement and the new term 
loan facility under the 2014 Credit Agreement was not considered a substantial modification.

The revolving credit facility includes a subfacility for swingline loans of up to $10.0 million, and up to $10.0 million of the 
revolving credit facility is available for the issuance of letters of credit. The term loan facility will amortize in quarterly installments 
in amounts resulting in an annual amortization of 5% during each of the first, second and third years, 10% during the fourth year 
and 15% during the fifth year after the Closing Date, with the remainder payable at final maturity. The loans under the 2014 Credit 
Agreement bear interest, at the Company's option, either (i) during any interest period selected by the Company, at the London 
interbank offered rate for deposits in U.S. dollars with a maturity comparable to such interest period, adjusted for statutory reserves 
(“LIBOR”), plus an initial spread of 2.00% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio (as 
defined in the 2014 Credit Agreement) of the Company, or (ii) at the greatest of (x) the prime rate from time to time announced 
by JPMorgan Chase Bank, N.A., (y) the federal funds effective rate plus 0.5% and (z) LIBOR for a one-month interest period plus 
1.00%, plus an initial spread of 1.00% per annum, subject to adjustment based on the First Lien Secured Leverage Ratio of the 
Company. If an event of default occurs under the 2014 Credit Agreement, the interest rate on overdue amounts will increase by 
2.00% per annum. The obligations under the 2014 Credit Agreement are guaranteed by all material subsidiaries of the Company 
and are secured by a lien on substantially all of the assets of the Company and those of its material subsidiaries, in each case subject 
to certain exceptions, pursuant to security and guarantee documents entered into on the Closing Date.  

The 2014 Credit Agreement requires the Company to maintain (i) a First Lien Secured Leverage Ratio (as defined in the 2014 
Credit Agreement) not exceeding 4.00 to 1.00 during each full fiscal quarter after the Closing Date through the three months ended 
March 31, 2016, and 3.50 to 1.00 thereafter and (ii) after the incurrence of additional indebtedness under certain specified exceptions 
in the 2014 Credit Agreement, a Total Leverage Ratio (as defined in the 2014 Credit Agreement) not exceeding 5.00 to 1.00 during 
each full fiscal quarter after the Closing Date through the three months ended March 31, 2016, and 4.50 to 1.00 thereafter. The 
2014 Credit Agreement also includes other covenants, including covenants that, subject to certain exceptions, restrict the ability 
of the Company and its subsidiaries to (i) incur additional indebtedness, (ii) create, incur, assume or permit to exist any liens, (iii) 
enter into mergers, consolidations or similar transactions, (iv) make investments and acquisitions, (v) make certain dispositions 
of assets, (vi) make dividends, distributions and prepayments of certain indebtedness, and (vii) enter into certain transactions with 
affiliates. The Company was in compliance with the covenants in the 2014 Credit Agreement as of December 31, 2015.

In connection with obtaining the term loan facility and revolving credit facility pursuant to the 2014 Credit Agreement, the 
Company incurred approximately $10.1 million in debt issuance costs as of April 1, 2014. The debt issuance costs were comprised 
of approximately $9.7 million in underwriting fees and approximately $400,000 primarily related to legal fees associated with the 
debt issuance. Approximately $10.0 million of the fees associated with the refinancing, along with the unamortized debt issuance 
cost from the 2012 Credit Agreement were capitalized and are amortized as interest expense over the term of the 2014 Credit 
Agreement using the effective interest method. 

As of December 31, 2014 and 2015, no amounts were outstanding under the revolving credit facilities. Total interest expense 
for the term loan facilities and revolving credit facilities was approximately $6.9 million, $10.5 million and $9.4 million for the 
years  ended  December 31,  2013,  2014  and  2015,  respectively.  Interest  expense  included  amortized  debt  issuance  costs  of 
approximately $3.0 million, $3.3 million and $3.3 million for the years ended December 31, 2013, 2014 and 2015, respectively. 
Total interest paid for the term loan facilities was approximately $4.3 million, $7.0 million and $6.1 million for the years ended 
December 31, 2013, 2014 and 2015, respectively.

As of December 31, 2014 and 2015, a valuation allowance has been established for certain deferred tax assets due to the 
uncertainty of realization. The valuation allowance as of December 31, 2014 includes an allowance for unrealized losses on ARS 
investments and foreign deferred tax assets. The valuation allowance as of December 31, 2015 includes an allowance for unrealized 
losses on ARS investments, foreign deferred tax assets and state net operating losses and tax credits. The valuation allowance for 
the deferred tax asset for unrealized losses on ARS has been recorded as an adjustment to accumulated other comprehensive loss. 

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

The Company’s change in valuation allowance was a decrease of approximately $3.2 million for the year ended December 31, 
2014  and  an  increase  of  approximately  $1.6  million  for  the  year  ended  December 31,  2015. The  increase  for  the  year  ended 
December 31, 2015 is due to an increase in the valuation allowance for U.S. deferred tax assets of approximately $2.2 million 
primarily related to the change in local tax law that occurred during the first quarter of 2015, partially offset by the decrease in 
the valuation allowance for foreign deferred tax assets of approximately $551,000.

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. At the present time, 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, management has concluded that it is not probable that a loss 
has been incurred in connection with the Company’s current litigation. In addition, the Company is unable to estimate the possible 
loss  or  range  of  loss  that  could  result  from  an  unfavorable  outcome  in  the  Company’s  current  litigation  and  accordingly,  the 
Company has not recognized any liability in the consolidated financial statements for unfavorable results, if any. Legal defense 
costs are expensed as incurred.

SEGMENT REPORTING

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 parts of Canada, and International, which includes parts of 
the  U.K.,  Spain  and  France. The  Company  and  its  subsidiaries'  subscription-based  services  consist  primarily  of  information, 
analytics and online marketplace services offered over the Internet to commercial real estate industry and related professionals. 
The Company’s subscription-based information services consist primarily of CoStar SuiteTM services. CoStar Suite is sold as a 
platform of service offerings consisting of CoStar Property Professional®, CoStar COMPS Professional® and CoStar Tenant® 
and through the Company's mobile application, CoStarGo®.  CoStar Suite is the Company’s primary service offering in the North 
America and International operating segments. Management relies on an internal management reporting process that provides 
revenue and operating segment EBITDA, which is the Company’s net income (loss) before interest, income taxes, depreciation 
and amortization. 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.

STOCKHOLDERS’ EQUITY

Preferred Stock

The Company has 2,000,000 shares of preferred stock, $0.01 par value, authorized for issuance as of December 31, 2015. The 

Board of Directors may issue the preferred stock from time to time as shares of one or more classes or series.

Common Stock

The Company has 60,000,000 shares of common stock, $0.01 par value, authorized for issuance. Dividends may be declared 
and paid on the common stock, subject in all cases to the rights and preferences of the holders of preferred stock and authorization 
by the Board of Directors. In the event of liquidation or winding up of the Company and after the payment of all preferential 
amounts required to be paid to the holders of any series of preferred stock, any remaining funds shall be distributed among the 
holders of the issued and outstanding common stock.  

Equity Offering

During June 2014, the Company completed a public equity offering of 3,450,000 shares of common stock for $160.00 per 
share. Net proceeds from the public equity offering were approximately $529.4 million, after deducting approximately $22.1 
million of underwriting discounts and commissions and offering expenses of approximately $500,000. The Company has used 
and intends to continue to use the net proceeds from the sale of the securities to fund all or a portion of the costs of any strategic 
acquisitions it determines to pursue, to finance the growth of its business and for general corporate purposes. General corporate 
purposes  may  include  additions  to  working  capital,  capital  expenditures,  repayment  of  debt,  investments  in  the  Company’s 
subsidiaries, possible acquisitions and the repurchase, redemption or retirement of securities, including the Company’s common 
stock.

Employee stock options with exercise prices greater than the average market price of the Company’s common stock for the 
period are excluded from the calculation of diluted net income per share as their inclusion would be anti-dilutive. Additionally, 
shares of restricted common stock that vest based on Company performance and service 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. Finally, shares of restricted 
common stock units that vest based on Company service 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.

NET INCOME (LOSS) PER SHARE — (CONTINUED)

Other than the shares of restricted common stock that vest based on Company performance conditions, no other potential 
common shares were excluded from the calculation of diluted net income for the year ended December 31, 2013. Stock options 
to purchase approximately 80,000 shares that were outstanding for the year ended December 31, 2014 were not included in the 
computation of diluted net income per share because the exercise price of the stock options was greater than the average market 
share price of the common stock during the period. The Company did not consider the impact of potentially dilutive securities for 
the year ended December 31, 2015 when calculating the diluted net loss per share because the inclusion of the potentially dilutive 
common shares would have an anti-dilutive effect.  Shares underlying restricted common stock awards and restricted stock units 
that vest based on Company performance and/or service 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. The following table summarizes the shares underlying the

In June 1998, the Company’s Board of Directors adopted the 1998 Stock Incentive Plan (as amended, the “1998 Plan”) prior 
to consummation of the Company’s initial public offering. 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. All shares of common stock that were authorized for issuance under the 1998 Plan that, as of June 7, 2007, remained 
available for issuance under the 1998 Plan (excluding shares subject to outstanding awards) were rolled into the 2007 Plan and, 
as of that date, no shares of common stock were available for new awards under the 1998 Plan. The 1998 Plan continues to govern 
unexercised and unexpired awards issued under the 1998 Plan prior to June 7, 2007. The 1998 Plan provided for the grant of stock 
and stock options to officers, directors and employees of the Company and its subsidiaries. Stock options granted under the 1998 
Plan could be incentive or non-qualified, and the exercise price for an incentive 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 and restricted stock grants under 
the 1998 Plan was determined by the Board of Directors or a committee thereof and was generally three to four years. Upon the 
occurrence of a Change of Control, as defined in the 1998 Plan, all outstanding unexercisable options and restricted stock grants 
under the 1998 Plan immediately become exercisable.

Stock Incentive Plans — (Continued)

The 2007 Plan provides for the grant of stock options, restricted stock, restricted stock units, and stock appreciation rights to 
officers, employees, directors and consultants of the Company and its subsidiaries. Stock options granted under the 2007 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 2007 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 2007 Plan 
may be based on performance conditions. The Company has issued and/or reserved the following shares of common stock for 
issuance under the 2007 Plan (including an increase of 1,300,000 shares of common stock pursuant to an amendment to the 2007 
Plan approved by the Company’s stockholders on June 2, 2010 and an increase of 900,000 shares of common stock pursuant to 
an amendment to the 2007 Plan approved by the Company’s stockholders on June 5, 2012): (a) 3,200,000 shares of common stock, 
plus (b) 121,875 shares of common stock that were authorized for issuance under the 1998 Plan that, as of June 7, 2007, remained 
available for issuance under the 1998 Plan (not including any Shares that were subject as of such date to outstanding awards under 
the 1998 Plan), and (c) any shares of common stock subject to outstanding awards under the 1998 Plan as of June 7, 2007, 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 2007 Plan will 
terminate in April 2017, but will continue to govern unexercised and unexpired awards issued under the 2007 Plan prior to that 
date. Approximately 1.2 million and 1.0 million shares were available for future grant under the 2007 Plan as of December 31, 
2014 and 2015, respectively.

At December 31, 2015, there was $61.7 million of unrecognized compensation cost related to stock incentive plans, net of 

forfeitures, which the Company expects to recognize over a weighted-average-period of 2.4 years.

The aggregate intrinsic value is calculated as the difference between (i) the closing price of the common stock at the end of 
the period and (ii) the exercise prices of the underlying awards, multiplied by the shares underlying options as of the end of the 
period that had an exercise price less than the closing price on that date. Options to purchase 409,799, 68,126 and 59,602 shares 
were exercised during the years ended December 31, 2013, 2014, and 2015, respectively. The aggregate intrinsic value of options 
exercised, determined as of the date of option exercise, was $39.0 million, $8.9 million and $6.8 million for the years ended 
December 31, 2013, 2014, and 2015, respectively.

The weighted-average grant date fair value of each option granted during the years ended December 31, 2013, 2014 and 2015 

using the Black-Scholes option-pricing model was $34.10, $58.12 and $56.53, 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:

Dividend yield
Expected volatility

The assumptions above and the estimation of expected forfeitures are based on multiple factors, including historical employee 
behavior patterns of exercising options and post-employment termination behavior, expected future employee option exercise 
patterns, and the historical volatility of the Company’s stock price.

Restricted Stock Awards

In February 2012, the Compensation Committee of the Board of Directors of the Company approved grants of restricted 
common stock to the executive officers that vest based on the achievement of certain performance conditions. 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. In May and December of 2012, the Company granted additional 
shares of restricted common stock that vest based on the achievement of certain performance conditions to other employees. These 
shares  of  performance-based  restricted  common  stock  vest  upon  the  Company’s  achievement  of  $90.0  million  of  cumulative 
EBITDA over a period of four consecutive calendar quarters, and are subject to forfeiture in the event the foregoing performance 
condition is not met by March 31, 2017. The Company granted a total of 399,413 shares of performance-based restricted common 
stock during the year ended December 31, 2012. All of the awards were made under the 2007 Plan and pursuant to the Company’s 
standard form of restricted stock grant agreement. The number of shares granted was based on the fair market value of the Company’s 
common stock on the grant date. As of March 31, 2014, the Company had satisfied all performance conditions and the award 
recipients had satisfied all service conditions, and as a result, the restricted common stock granted under these awards vested. The 
Company recorded approximately $21.8 million, $2.2 million and $0 of stock-based compensation expense related to the 2012 
performance-based restricted common stock for the years ended December 31, 2013, 2014 and 2015, respectively.

In February 2014, the Compensation Committee of the Board of Directors of the Company approved grants of restricted 
common stock to the executive officers that vest based on the Company’s achievement of a three-year cumulative revenue goal 
established at the grant date, and are subject to forfeiture in the event the foregoing performance condition is not met by December 
31, 2016. In March 2015, the Compensation Committee of the Board of Directors of the Company approved grants of restricted 
common stock to the executive officers that vest based on the Company’s achievement of a three-year cumulative revenue goal 
established at the grant date, and are subject to forfeiture in the event the foregoing performance condition is not met by December 
31, 2017. The number of shares that may be earned ranges between 0% (if the specified threshold performance level is not attained) 
and 200% (if performance meets or exceeds the maximum achievement level) of the target award. If actual performance exceeds 
the pre-established threshold, the number of shares earned is calculated based on the relative performance between specified levels 
of achievement. These awards support the Company’s goals of aligning executive incentives with long-term stockholder value 
and ensuring that executive officers have a continuing stake in the long-term success of the Company. 

 The 2014 and 2015 performance-based restricted common stock awards are subject to continuing employment requirements 
and to a market condition. The actual number of shares that vest at the end of the respective three-year period is determined based 
on the Company’s achievement of the three-year performance goals described above, as well as its TSR 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 80.0% and 120.0%, based on the Company’s TSR performance relative to that of the Russell 
1000 Index over the respective three-year period. The Company granted a total of 24,720 shares of 2014 performance-based 
restricted  common  stock  during  the  year  ended  December 31,  2014  and  a  total  of  32,400  shares  of  2015  performance-based 
restricted common stock during the year ended December 31, 2015.

The Company estimates the fair value of its performance-based restricted common stock awards with a 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 the Company achieving various stock price levels to determine the expected TSR performance ranking. Expense is 
only recorded for awards that are expected to vest, net of estimated forfeitures. The assumptions used to estimate the fair value of 
performance-based restricted common stock awards with a market condition granted were as follows:

As of December 31, 2015, the Company reassessed the probability of achieving the performance and market conditions and 
determined that it was probable that the performance and market conditions for the 2014 and 2015 performance-based restricted 
common stock awards would be met by their forfeiture dates. As a result, the Company recorded a total of approximately $1.1 
million and $2.8 million of stock-based compensation expense related to the performance-based restricted common stock awards 
with a market condition for the years ended December 31, 2014 and 2015, respectively. The Company expects to record an estimated 
stock-based compensation expense related to the performance-based restricted common stock awards of approximately $5.3 million 
over the periods 2016, 2017 and 2018.

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 2013, 2014 and 2015, 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, 2013, 2014 and 2015 were approximately $5.1 million, $6.1 million and $7.5

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 2013, 2014 and 2015, 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,  2013,  2014  and  2015  were 
approximately $280,000, $390,000 and $420,000, 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 2015, 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  for  the  year  ended 
December 31, 2015 were approximately $40,000.

 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 21,774 and 108,547 shares available for purchase 
under the ESPP as of December 31, 2014 and 2015, respectively, and approximately 13,121 and 13,227 shares of the Company’s 
common stock were purchased under the ESPP during 2014 and 2015, respectively.
