To Our Shareholders

CoStar Group 1987 – 2007 
Celebrating 20 Years of Success  

–  And Setting the Stage for the 

Next  20  Years  of  Earnings  and 

Revenue Growth

CoStar  Group  Inc.  celebrated 

its  20th  year  in  operation  in 

2007  by  signifi cantly  expand-

ing  our  research  platform  in  both  the  United  States 

and  United  Kingdom,  generating  strong  earnings 

and  growing  revenue  to  the  highest  level  in  our  com-

pany’s  history,  adding  yet  another  chapter  to  the 

extraordinary  growth  story  that  has  characterized 

CoStar for the past two decades. 

While it is certainly worthwhile and appropriate to refl ect 

on what our company has accomplished in 20 years, I am 

even  more  excited  about  our  future.  The  potential  size 

of the global market I see for our company’s information 

services  is  vast,  the  demand  for  our  research-verifi ed, 

comprehensive information is growing, and CoStar’s role 

in  serving  this  key  investment  asset  class  continues  to 

expand. 

During 2007, CoStar achieved an important milestone by 

fulfi lling our long-held goal of covering U.S. commercial 

property markets coast-to-coast. We also completed the 

integration  of  a  major  property  type  –  retail  –  into  our 

information  service,  enhancing  the  value  of  our  service 

for  current  customers,  and  signifi cantly  expanding  our 

potential  customer  base  to  include  retail  real  estate-

focused fi rms that are not current subscribers. 

We  began  the  year  by  making  a  key  acquisition  in  the 

United Kingdom where we are working to fully establish 

our research platform, following the model we have used 

successfully  in  the  U.S.    We  expect  our  European  busi-

ness to continue to grow and expand, creating the poten-

tial to provide more value to our customers and increase 

shareholder value for years to come.

2007 a Turning Point

In many ways, 2007 was a pivotal year for CoStar, one that marked the 

“Confi dent in our ability to con-

end of a signifi cant chapter in our development as a company, and 

the start of another. Last year, we completed our U.S. market expan-

tinue generating robust growth 

sion  following  the  culmination  of  a  long  period  of  intensive  invest-

in  our  earnings  following  the 

completion  of  this  latest  and 

most  extensive  expansion,  we 

announced  our  expectation 

of  achieving  a  30%  EBITDA 

margin  in  our  U.S.  operations 

and break-even in our interna-

tional  operations  by  the  end 

of 2008.”

ment. Now, we are transitioning into a new phase, one in which we 

are focusing intently on generating the signifi cant return we expect 

from that investment in our U.S. operations.  

As you can see by our fi nancial results presented in this annual report, 

that transition has already begun. CoStar began generating increas-

ing earnings in the second half of 2007, and we expect to continue to 

do so through 2008.  

Our fi nancial performance for the year included a 28.5% increase in 

net income to $16.0 million for 2007, or $0.82 per diluted share, com-

pared to $12.4 million, or $0.65 per diluted share for 2006.  EBITDA 

(earnings  before  interest,  taxes,  deprecation  and  amortization)  for 

the year was $34.0 million, an increase of 31.3% compared to EBITDA 

of $25.9 million in 2006. Our revenue in 2007 reached $192.8 million, 

an increase of 21.3% over revenues of $158.9 million in 2006.

I believe the overall earnings picture for us in 2008 is quite positive. 

Demand  for  our  information  products  and  services  remains  strong, 

our existing markets are showing continued consistent growth, and 

our recent investments have created additional growth drivers. 

The continued high renewal rates among existing customers and on-

going growth in our subscriber base, coupled with a stabilized cost 

basis following the completion of our recent U.S. market expansion, 

have all contributed to our earnings growth. And we are very confi -

dent in our ability to continue generating robust earnings. Following 

the completion of this latest and most extensive expansion, we an-

nounced  our  expectation  of  achieving  a  30%  EBITDA  margin  in  our 

U.S. operations and break-even in our international operations by the 

end of 2008.

“A compelling picture emerges 

made CoStar an indispensable “must have” for commercial property 

professionals, which is clearly illustrated by the high subscription re-

newal rates CoStar enjoys.

One event from 2007 that I believe truly reveals how important and 

how integrated CoStar’s information has become among today’s com-

mercial  real  estate  service  providers,  is  the  long-term,  enterprise-

wide agreement CoStar signed with CB Richard Ellis, Inc., the world’s 

largest commercial real estate services fi rm. 

The agreement, which covers a potential term of 11 years, represents 

the  largest  fi nancial  commitment  CoStar  has  ever  received  from  a 

single client, with a potential value exceeding $100 million in revenue 

over the entire term. 

The  fact  that  CB  Richard  Ellis,  along  with  the  majority  of  the  com-

mercial real estate industry’s largest and most infl uential fi rms, have 

when CoStar’s fi nancial perfor-

mance is viewed from the van-

tage  point  of  a  20-year  track 

record  showing  the  results  of 

a strong fi nancial performance 

and  steady  revenue  growth  – 

quarter  to  quarter  and  year 

over  year  –  that  conclusively 

demonstrates  the  validity  and 

remarkable consistency of our 

business  model  in  generating 

committed to CoStar as their trusted source of reliable and valuable 

a pattern of increasing rates of 

return on investment.”

data underscores our value proposition as the industry’s leading in-

formation service provider. Increasingly, these clients recognize that 

CoStar’s expanded national coverage, advanced technology platform 

and high quality information empowers commercial real estate pro-

fessionals to be more productive – and profi table – by saving them 

research time, allowing them to close more deals and generate more 

income. By making such high quality information available across all 

markets at a reasonable cost, CoStar solves a key business need, en-

abling real estate service providers to focus their resources, both hu-

man and fi nancial, on their clients.

A Growth Model To Build On

CoStar achieved many milestones and accomplishments in building 

“While  it  is  certainly  worth-

the  industry’s  largest  database  of  commercial  property  information 

over the past 20 years, including: assimilating the databases of more 

while and appropriate to refl ect 

than  two  dozen  companies;  establishing  the  industry’s  largest  re-

even  more  excited  about  our 

cycles; and expanding market coverage to include the United States, 

United Kingdom and Paris, France.

Taken individually, each accomplishment made over the years had a 

signifi cant impact on our business at the time and helped us to be-

future.  The  potential  size  of 

the global market I see for our 

company’s  information  servic-

come the fi rm we are today. However, an even more compelling pic-

es is vast, the demand for our 

ture emerges when CoStar’s fi nancial performance is viewed from the 

vantage point of a 20-year track record showing the results of a strong 

research-verifi ed,  comprehen-

fi nancial performance and steady revenue growth – quarter to quarter

and year over year – that conclusively demonstrates the validity and 

remarkable  consistency  of  our  business  model  in  generating  a  pat-

and  CoStar’s  role  in  serving 

tern of increasing rates of return on investment in the vast majority of 

this key investment asset class 

markets across the U.S. 

continues to expand.”

Revenues associated with a specifi c market generally reach profi tabil-

ity within approximately two years of initiating sales for our informa-

tion service, following the initial investment CoStar makes to catalog, 

photograph, geo-code and verify detailed information on commercial 

buildings, properties and parcels within that market. After becoming 

profi table, our markets generally continue to produce sustained rev-

enue growth for years following initial investment.

CoStar has successfully repeated this same model in many markets 

throughout the U.S. for the past 20 years. And, as our fi nancial per-

formance has clearly demonstrated, the process of growing revenue 

from  our  information  service  over  time  –  from  initial  acceptance  to 

ultimately  becoming  an  indispensable  resource  for  the  market  – 

is something we have achieved time and again.

Generally, the fi rst CoStar subscribers within a specifi c market tend 

to be the largest commercial brokerage fi rms. As they adopt and inte-

grate our service into their day-to-day operations, they realize the ad-

vantages and increased productivity achievable as a result of having 

access to a high quality information service. This typically results in 

stronger demand for our service among midsize and smaller brokers.

The  constant  recruitment  and  movement  of  personnel  from  fi rm 

“By  making 

it  possible  to

demand  for  our  service.  Brokers  who  benefi ted  from  having  access

information.

Since  CoStar  has  become  the  digital  information  clearinghouse  for 

commercial real estate, transforming a formerly ineffi cient, labor-in-

tensive, paper-based information exchange plagued by inconsistent 

quality standards and market defi nitions, the availability and overall 

quality  of  information  has  improved  enormously.  At  the  same  time, 

broker  effi ciency  has  dramatically  increased  and  transaction  costs 

have  fallen  due  to  the  effi cient  exchange  of  information  among  the 

various stakeholders involved in commercial property transactions.

Subscribers  can  use  CoStar  to  access  the  same  high  quality  infor-

mation in any or all of the other markets CoStar covers. That means  

they  can  more  readily  expand  their  scope  of  business  well  outside 

their traditional market or submarket, thereby more capably handling 

their clients’ real estate needs wherever their business takes them, a 

key driver behind the increased demand for our U.S. national service 

subscription.

formation on commercial prop-

erty assets internationally.”

We see a far more sophisticated, global industry emerging in the not-

too-distant future, one that will require access to standardized, high 

quality information on commercial property assets internationally. As 

a result, in 2007 CoStar began developing a global version of our fl ag-

ship  CoStar  Property  Professional®  product.  When  fully  developed, 

this  new  version  will  provide  the  same  advanced  software  platform 

and standardized, high quality information and make it more acces-

sible to any user around the globe, by automatically displaying the 

information using local currency, language and measurements. 

If  the  two  decades  we  have  been  in  business  are  any  indication, 

the changes we will see in the commercial real estate industry will be 

profound,  driven  by  the  ongoing  globalization  of  the  securities  and 

debt markets in the digital economy. 

We believe an exciting time is ahead for our industry, and CoStar will 

be at the center of commercial real estate information services when 

that transformation occurs.

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 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, is the leading provider of information services 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, 
provide more information services than any of our competitors and believe we generate more revenues than any of 
our  competitors.  CoStar’s  integrated  suite  of  services  offers  customers  online  access  to  the  most  comprehensive 
database of commercial real estate information, which has been researched and verified by our team of researchers, 
currently covering the U.S., as well as London and other parts of the U.K. and parts of France. Prior to 2007, CoStar 
operated within one segment. Due to the increased size, complexity and funding requirements associated with our 
international expansion in 2007, we began to manage our business geographically in two operating segments, with 
our primary areas of measurement and decision-making being the U.S. and International, which includes the U.K. 
and France. 

Since  our  founding  in  1987,  CoStar’s  strategy  has  been  to  provide  commercial  real  estate  professionals  with 
critical  knowledge  to  explore  and  complete  transactions,  by  offering  the  most  comprehensive,  timely  and 
standardized  information  on  U.S.  commercial  real  estate.  As  a  result  of  our  January  2003  acquisition  of  Focus 
Information  Limited,  June  2004  acquisition  of  Scottish  Property  Network,  December  2006  acquisition  of  Grecam 
S.A.S., and February 2007 acquisition of Property Investment Exchange Limited, we have extended our offering of 
comprehensive  commercial  real  estate  information  to  include  London  and  other  parts  of  the  U.K.  and  parts  of 
France.  Information about CoStar’s revenues from, and long-lived assets located in, foreign countries is included in 
Notes 2 and 10 to our consolidated financial statements. CoStar’s revenues, net income, assets and liabilities, broken 
out by segment are set forth in Note 10 to our consolidated financial statements.  Information about risks attendant 
to our foreign operations is included in “Item 7A. Quantitative and Qualitative Disclosures about Market Risk.”   

We deliver our content to our U.S. customers via an integrated suite of online service offerings that includes 
information  about  space  available  for  lease,  comparable  sales  information,  tenant  information,  information  about 
properties  for  sale,  property  information  for  clients’  websites,  information  about  industry  professionals  and  their 
business  relationships,  analytic  information,  data  integration,  property  marketing  and  industry  news.    We  have 
created  and  are  continually  improving  a  standardized  information  platform  where  the  commercial  real  estate 
industry  and  related  businesses  can  continuously  interact  and  easily  facilitate  transactions  due  to  the  efficient 
exchange of accurate information supplied by CoStar. 

We have a number of assets that provide a unique foundation for our standardized platform, including 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  services;  and  a  large  base  of  clients.  Our  database  has  been  developed  and 
enhanced  for  more  than  20  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 over 51 proprietary databases.   

CoStar intends to continue to grow its standardized platform of commercial real estate information.  In 2004, 
CoStar began research for a 21-market U.S. expansion effort.  In the first quarter of  2006, CoStar had successfully 
launched service in each of those 21 markets.  In addition, following our acquisition of National Research Bureau in 
January 2005, we launched various research initiatives as part of our expansion into real estate information for retail 
properties.  In July 2006, we announced our intention to commence actively researching commercial properties in 
approximately  81  new  Core  Based  Statistical  Areas  (“CBSAs”)  across  the  U.S.  in  an  effort  to  expand  the 
geographical coverage of our service offerings, including our new retail service. In the fourth quarter of 2007, we 
released our CoStar Property Professional service in the 81 new CBSAs across the U.S.   

3 

 
 
 
 
 
 
 
 
CoStar  also  intends  to  continue  to grow  and  expand  the  coverage  of  its  service offerings  within  the U.K.    In 
December  2006,  CoStar’s  U.K.  Subsidiary,  CoStar  Limited,  acquired  Grecam  S.A.S.,  a  provider  of  commercial 
property  information  and  market-level  surveys,  studies  and  consulting  services,  located  in  Paris,  France.    In 
February  2007,  CoStar  Limited  also  acquired  Property  Investment  Exchange  Limited,  a  provider  of  commercial 
property information and operator of an online investment property exchange located in London, England.  CoStar 
intends to integrate its U.K. and French operations more fully with its U.S. operations and eventually to introduce a 
consistent international platform of service offerings.        

Our  subscription-based  information  services,  consisting  primarily  of  CoStar  Property  Professional,  CoStar 
Tenant,  CoStar  COMPS  Professional  and  FOCUS  services,  currently  generate  approximately  95%  of  our  total 
revenues. Our contracts for our subscription-based information services typically have a minimum term of one year 
and renew automatically. Upon renewal, many of the subscription contract rates  may increase 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 fees based on actual system 
usage.  Contract  rates  are  based  on  the  number  of  sites,  number  of  users,  organization  size,  the  client’s  business 
focus,  geography  and  the  number  of  services  to  which  a  client  subscribes.  Our  subscription  clients  generally  pay 
contract fees on a monthly basis, but in some cases may pay us on a quarterly or annual basis.   

Industry Overview  

The market for commercial real estate information 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. 
Members of the commercial real estate and related business community require daily access to current data such as 
space  availability,  rental  rates,  vacancy  rates,  tenant  movements,  sales  comparables,  supply,  new  construction, 
absorption rates and other important market developments to carry out their businesses effectively. There is a strong 
need  for  an  efficient  marketplace,  where  commercial  real  estate  professionals  can  exchange  information,  evaluate 
opportunities using standardized data and interact with each other on a continuous basis. 

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

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

Sales and leasing brokers 
Property owners 
Property managers 

• 
• 
• 
•  Design and construction professionals 
•  Real estate developers 
•  Real estate investment trust managers 
• 
Investment bankers 
•  Commercial bankers 
•  Mortgage bankers 
•  Mortgage brokers 
•  Retailers 

Pension fund managers 

•  Government agencies’ staff members 
•  Mortgage-backed security issuers 
•  Appraisers 
• 
•  Reporters 
•  Tenant vendors 
•  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,  easy  to  use  technology  and 
intensive  participant  interaction.  By  combining  its  extensive  database,  1,041  researchers  and  outside  contractors, 
technological expertise and broad customer base, CoStar believes that it has created such a platform.

CoStar’s Comprehensive Database  

CoStar has spent more than 20 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. 

As of January 31, 2008, our database of real estate information covered the U.S., as well as London, England 

and other parts of the U.K. and parts of France, and contained: 

•  More than 67.2 billion square feet (gross building area) and more than 53.9 billion square feet (rentable 

building area) of U.S. commercial real estate; 

•  More than 940,000 sale and lease listings; 
•  Over 2.7 million total properties; 
•  Over 7.0 billion square feet of sale and lease listings; 
•  Over 5.5 million tenants; 
•  More than 1.2 million sales transactions valued in the aggregate at over $2.8 trillion; and 
•  Approximately 5.6 million digital attachments, including building photographs, aerial photographs, 

plat maps and floor plans. 

This highly complex database is comprised of hundreds of data fields, tracking such categories as: 

Site and zoning information 

•  Location 
• 
•  Building characteristics 
• 
Space availability 
•  Tax assessments 
•  Ownership 
Sales and lease comparables 
• 
• 
Space requirements 
•  Number of retail stores  

For-sale information 
Income and expense histories 

•  Mortgage and deed information 
• 
• 
•  Tenant names 
•  Lease expirations 
•  Contact information 
•  Historical trends 
•  Demographic information 
•  Retail sales per square foot 

CoStar Research 

We  have  developed  a  sophisticated  data  collection  organization  utilizing  a  multi-faceted  research  process.  In 
2007, our full time researchers and contractors drove millions of miles, conducted hundreds of thousands of on-site 
building inspections, and conducted millions interviews of brokers, owners and tenants. 

Research Department. As of January 31, 2008, we employed 869 commercial real estate research professionals 
and  172  individuals  acting  as  outside  contractors  performing  research.    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,  internet  updates  and  faxes  each  year, in  addition  to  field  inspections,  public  records  review, 
news  monitoring  and  direct  mail.  Each  researcher  is  responsible  for  maintaining  the  accuracy  and  reliability  of 
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.  In 2007, we continued 
outsourcing a limited number of research related projects to outside firms to supplement the work of our research 
employees. 

CoStar has an extensive field research effort that includes physical inspection of properties in order to research 
new  markets,  find  additional  inventory,  photograph  properties  and  verify  existing  information.  CoStar’s  research 
efforts  have  traditionally  focused  on  office  and  industrial  properties.    Following  our  acquisition  of  National 
Research  Bureau  in  January  2005,  we  launched  a  major  expansion  effort  into  real  estate  information  for  retail 
properties.  In July 2006, we announced our intention to commence actively researching commercial properties in 

5 

 
 
 
 
 
 
 
 
 
 
 
approximately  81  new  CBSAs  across  the  U.S.  in  an  effort  to  expand  the  geographical  coverage  of  our  service 
offerings,  including  our  new  retail  service.    In  the  fourth  quarter  of  2007,  we  released  the  CoStar  Property 
Professional service in the 81 new CBSAs across the U.S. 

As part of CoStar’s research efforts, CoStar utilizes 152 high-tech field research vehicles in 43 states and the 
U.K.    Of  these  vehicles,  101  are  custom-designed  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.    Some  of  our 
researchers also use custom-designed trucks with the same equipment as well as pneumatic masts that extend up to 
an  elevation  of  twenty-five  feet  to  allow  for  unobstructed  building  photographs  from  “birds-eye”  views.    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,  interviewing  tenants  suite  by  suite.  In  addition,  many  of  our 
field  researchers  are  photographers  who  take  photographs  of  commercial  real  estate  properties  to  add  to  CoStar’s 
database of digital images.   

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  and  aerial 
photographs,  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  services  and 
include  what  we  believe  are  standard  terms,  such  as  a  contract  term  ranging  from  two  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 all 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 

As of January 31, 2008, CoStar had a staff of 101 product development, database and network professionals.  
CoStar’s information technology professionals focus on developing new services for our customers and delivering 
research automation tools that improve the quality of our data and increase the efficiency of our research analysts.  

Our  information  technology  team  is  responsible  for  developing  and  maintaining  CoStar  products  including 
CoStar Property Professional, CoStar Property Express, CoStar COMPS, CoStar Tenant, CoStar CMLS and CoStar 
Connect and for our international products.  In 2006, CoStar released a major upgrade to its CoStar COMPS service 
that provides customers with over 100 improvements, including access to for sale information, aerials and enhanced 
mapping.  In 2007, to better support our retail customers, we added significant features to CoStar Property including 
tenant  proximity  and  demographic  search  capability,  mapping  layers,  detailed  retail  tenant  information  and 
demographics.   Also in 2007, CoStar began development of an international platform, which will allow CoStar to 
offer CoStar Property Professional in international countries.

Our information technology team is responsible for developing the infrastructure necessary to support CoStar’s 
business  processes,  our  comprehensive  database  of  commercial  real  estate  information  and  our  extensive  image 
library. The team implements technologies and systems that introduce efficient workflows and controls that increase 
the  production  capacity  of  our  research  teams  and  improve  the  quality  of  our  data.    Over  the  years,  the  team  has 
developed data collection and quality control mechanisms that we believe are unique to the commercial real estate 
industry. The team continues to develop and modify our enterprise information management system that integrates 
CoStar sales, research, field research, 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.   

Our  information  technology  professionals  also  maintain  the  servers  and  network  components  necessary  to 
support CoStar services and research systems.  Our encrypted virtual private network provides remote researchers 
and salespeople secure access to CoStar applications and network resources. CoStar maintains a comprehensive data 
protection policy  that  provides  for use  of  encrypted  data  fields  and  off-site  storage  of  all  system  backups,  among 
other protective measures.  CoStar’s services are continually monitored in an effort to ensure our customers fast and 
reliable access.   

Services 

Our suite of information services is branded and marketed to our customers. Our services are 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 enhance our existing information services 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 various information services are described in detail in the following paragraphs as of January 31, 2008: 

CoStar Property Professional®   CoStar Property Professional, or “CoStar Property,” is the Company’s flagship 
service. It provides subscribers a comprehensive inventory of office, industrial, retail and multifamily properties and 
land in markets throughout the U.S., including for-lease and for-sale listings, historical data, building photographs, 
maps and floor plans. Commercial real estate professionals use CoStar Property to identify available space for lease, 
evaluate leasing and sale opportunities, value assets and position properties in the marketplace. Our clients also use 
CoStar Property to analyze market conditions by calculating current vacancy rates, absorption rates or average rental 
rates,  and  forecasting  future  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 services, are delivered solely via the internet.   

CoStar COMPS Professional®   CoStar COMPS Professional provides comprehensive coverage of comparable 
sales information in the U.S. commercial real estate industry. It is the industry’s most comprehensive database of 
comparable sales transactions and is designed for professionals who need to research property comparables, identify 
market  trends,  expedite  the  appraisal  process  and  support  property  valuations.  In  November  2006,  we  launched  a 
major  upgrade  to  the  COMPS  Professional  service,  which  now  offers  subscribers  many  new  features,  including 
additional  fields  of  property  information,  access  to  support  documents  (e.g., deeds  of  trust)  for  new  comparables, 
demographics  and  the  ability  to  view  for-sale  properties  alongside  sold  properties  in  three  formats  –  plotted  on  a 
map, aerial image or in a table. 

CoStar  Tenant®      CoStar  Tenant  is  a  detailed  online  business-to-business  prospecting  and  analytical  tool 
providing  commercial  real  estate  professionals  with  the  most  comprehensive  commercial  real  estate-related  U.S. 
tenant  information  available.  CoStar  Tenant  profiles  tenants  occupying  space  in  commercial  buildings  across  the 
United States and provides updates on lease expirations -- one of the service’s key features -- as well as occupancy 
levels,  growth  rates  and  numerous  other  facts.  Delivering  this  information  via  the  internet  allows  users  to  target 
prospective clients quickly through a searchable database that identifies only those tenants meeting certain criteria.

CoStar Property Express®   CoStar Property Express provides access, via an annual subscription, to a “light” or

CoStar  Advertising®      CoStar  Advertising  offers  property  owners  a  highly  targeted  and  cost  effective  way  to 
market  a  space  for  lease  or  a  property  for  sale  directly  to  the  individuals  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.

For  the  years  ended  December  31,  2005,  2006  and  2007,  no  single  client  accounted  for  more  than  5%  of  our 

revenues.  

Sales and Marketing 

As of January 31, 2008, we had 265 sales, marketing and customer support employees, with the majority of our 
direct  sales  force  located  in  field  sales  offices.  Our  sales  teams  are  primarily  located  in  24  field  sales  offices 
throughout  the  U.S.  and  in  London,  England;  Manchester,  England;  Glasgow,  Scotland  and  Paris,  France.    Our 
inside  sales  team  is  located  in  our  Maryland  offices.  This  team  prospects  for  new  clients  and  performs  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 sales strategy is to aggressively attract new clients, while providing ongoing incentives for existing clients 
to subscribe to additional services. 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.   

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 services rather than fees based on 
actual system usage. Contract rates are based on the number of sites, number of users, organization size, the client’s 
business  focus,  geography  and  the  number  of  services  to  which  a  client  subscribes.  Our  subscription  clients 
generally  pay  contract  fees  on  a  monthly  basis,  but  in  some  cases  may  pay  us  on  a  quarterly  or  annual  basis.    In 
addition,  through  CoStar  Property  Express  and  CoStar  COMPS  Express,  clients  can  access  our  database  of 
commercial real estate information without a subscription on a pay per use basis. 

Our customer service and support staff is charged with ensuring high client satisfaction by providing ongoing 

customer support.  

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;  print  advertising  in  trade  magazines  and  local  business  journals;  client  referrals;  and 
CoStar  Advisor™,  the  Company’s  newsletter,  which  is  distributed  to  our  clients  and  prospects.  Web-based 
marketing and direct marketing are the most cost-effective means for us to find prospective clients. Our web-based 
marketing efforts include paid advertising with major search engines and commercial real estate news sites and our 
direct  marketing  efforts  include  direct  mail,  email  and  telemarketing,  and  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, and attend and/or exhibit at industry 
trade  shows  and  conferences  to  reinforce  our  relationships  with  our  core  user  groups,  including  industry-leading 
events for commercial brokers and retail and financial services institutions. 

Competition 

The  market  for  information  services  generally  is  competitive  and  rapidly  changing.  In  the  commercial  real 

estate industry, the principal competitive factors for commercial real estate information services and providers are: 

• 
• 
• 
• 
• 

quality and depth of the underlying databases;  
ease of use, flexibility, and functionality of the software;  
timeliness of the data;  
breadth of geographic coverage and services offered;  
client service and support;  

11 

 
 
 
 
 
 
 
 
 
 
 
• 
• 
• 
• 
• 
• 
• 

perception that the service offered is the industry standard;  
price;  
effectiveness of marketing and sales efforts;  
proprietary nature of methodologies, databases and technical resources; 
vendor reputation;  
brand loyalty among customers; and  
capital resources.  

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

• 

• 

• 

• 

• 

online  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  LoopNet,  Inc.,  Reed 
Business  Information  Limited,  Dorey  First  CLS,  officespace.com,  MrOfficeSpace.com  and  TenantWise, 
Inc; 

publishers  and  distributors  of  information  services,  including  regional  providers  and  national  print 
publications,  such  as  Black’s  Guide,  Property  and  Portfolio  Research,  Marshall  &  Swift,  Yale  Robbins, 
Inc., Reis, Inc., Real Capital Analytics, Dorey Publishing and Information Services and Smith Guide; 

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

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

public record providers.  

As the commercial real estate information marketplace develops, additional competitors (including companies 
which could have greater access to data, financial, product development, technical or marketing resources than we 
do) may enter the market and competition may intensify. While we believe that we have successfully differentiated 
ourselves from existing competitors, competition 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, copyright, trademark, database protection and other laws;  
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.  In 
addition, with respect to our U.K. databases, certain database protection laws provide additional protections of these 
databases. We license our services under license agreements that grant our clients non-exclusive, non-transferable 
licenses.  These  agreements  restrict  the  disclosure  and  use  of  our  information  and  prohibit  the  unauthorized 
reproduction or transfer of the information services we license. 

We  also  attempt  to  protect  the  secrecy  of  our  proprietary  database,  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 discourage and detect unauthorized copying of our intellectual 
property.

We have filed trademark applications to register trademarks for a variety of names for CoStar services and other 
marks, and have obtained registered trademarks for a variety of our marks, including “CoStar”, “COMPS”, “CoStar 
Property”, “CoStar Tenant” and “CoStar Group”. Depending upon the jurisdiction, trademarks are generally valid as 
long as they are in use and/or their registrations are properly maintained and they have not been found to become 
generic.    We  consider  our  trademarks  in  the  aggregate  to  constitute  a  valuable  asset.    In  addition,  we  have  filed 
several patent applications covering certain of our methodologies and software and currently have one patent in the 
U.K.  which  expires  in  2021  covering,  among  other  things,  certain  of  our  field  research  methodologies,  and  three 
patents in the U.S. which expire in 2020, 2021 and 2022, covering, among other things, critical elements of CoStar’s 
proprietary field research technology and mapping tools.  We regard the rights under our patents as valuable to our 
business but do not believe that our business is materially dependent on any single patent.  

Employees 

As of January 31, 2008, we employed 1,335 employees. None of our employees is represented by a labor union. 

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

contain  forward-looking  statements  include  “Business,”  “Risk  Factors,”  “Properties,”  “Legal  Proceedings,” 
“Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations,”  “Quantitative  and

Our  forward-looking  statements  are  also  identified  by  words  such  as  “believes,”  “expects,”  “thinks,” 
“anticipates,”  “intends,”  “estimates”  or  similar  expressions.  You  should  understand  that  these  forward-looking 
statements are necessary estimates reflecting our judgment, not guarantees of future performance. They are subject 
to  a  number  of  assumptions,  risks  and uncertainties  that  could  cause  actual  results  to differ  materially  from  those 
expressed  or  implied  in  the  forward-looking  statements.  The  following  important  factors,  in  addition  to  those 
discussed in “Risk Factors,” and other unforeseen events or circumstances, could affect our future results and could 
cause those results or other outcomes to differ materially from those expressed or implied in our forward-looking 
statements:  general  economic  conditions;  customer  retention;  competition;  our  ability  to  identify  and  integrate 
acquisitions;  our  ability  to  control  costs;  litigation;  our  ability  to  continue  to  expand  successfully;  our  ability  to 

13 

 
 
 
 
 
 
 
 
effectively  penetrate  the  market  for  retail  real  estate  information  and  gain  acceptance  in  that  market;  changes  or 
consolidations  within  the  commercial  real  estate  industry;  release  of  new  and  upgraded  services  by  us  or  our 
competitors; data quality; development of our sales force; employee retention; technical problems with our services; 
managerial execution; changes in relationships with real estate brokers and other strategic partners; foreign currency 
fluctuations; legal and regulatory issues; changes in accounting policies or practices; and successful adoption of and 
training on our services. 

Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the 
date of this report. All subsequent written and oral forward-looking statements attributable to us or any person acting 
on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this 
section. We do not undertake any obligation to update any such statements or release publicly any revisions to these 
forward-looking statements to reflect events or circumstances after the date of this report or to reflect the occurrence 
of unanticipated events. 

Risk Factors 

A  downturn  or  consolidation  in  the  commercial  real  estate  industry  may  decrease  customer  demand  for  our 
services. The continuing decline in the commercial real estate industry’s leasing activity, rental rates and absorption 
rates and the recent 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, both 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  services.  Also, 
companies  in  this  industry  are  consolidating,  often  in  order  to  reduce  expenses.  Consolidation  may  lead  to  more 
cancellations of our information 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 or our revenue 
growth rate to decline and reduce our profitability. 

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  services.  Our 
subscription-based information services generate the largest portion of our revenues. However, we may be unable to 
attract new clients in expansion markets, 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: 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  economic  or  competitive  pressures.  If  clients  decide  to  cancel  services  or  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, revenues and our revenue growth rate may decline. 

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,  inflation,  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.  Further, any significant terrorist attack is 
likely  to  have  a  dampening  effect  on  the  economy  in  general,  which  could  negatively  affect  our  financial 
performance  and our stock  price.  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. If clients choose 
to cancel our information services as a result of economic conditions, 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.  

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  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 

14 

 
 
 
 
 
 
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 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; 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. 

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 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, 
our  profitability  could  be  significantly  reduced  and  our  financial  position  could  be  adversely  affected. We  cannot 
assure you that we will have any or sufficient insurance to cover any litigation claims. 

If  our  operating  costs  are  higher  than  we  expect,  our  profitability  may  be  reduced.  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 revenue shortfall or increase in expenses. Additionally, 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 or cannot 
be adjusted accordingly, our profitability may be reduced and our results of operations and financial position will be 
adversely affected. 

If we are unable to enforce or defend our ownership and use of intellectual property, our business, competitive 
position and operating results could be harmed. The success of our business depends in large part on the intellectual 
property involved in our methodologies, database, services and software. We rely on a combination of 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 we cannot assure you of the future viability or value of any of our proprietary rights. Our business 
could be significantly harmed if we are not able to protect our content and our other intellectual property. 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 services and could reduce our profitability. 

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.  During  2007,  we  expanded 
geographic coverage in U.S. and U.K. and increased the depth of our coverage.  During 2008, we plan to increase 
the  depth  of  our  coverage  in  the  U.S.  and  U.K.  with  our  current  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 

Our continuing expansion into the retail real estate sector may not be completed successfully or may not result 
in  increased  revenues,  which  may  negatively  impact  our  business,  results  of  operations  and  financial  position. 
Expanding into the retail real estate sector imposes additional burdens on our research, systems development, sales, 
marketing and general managerial resources. During the next year, we expect to continue to expand the number of 

15 

 
 
 
 
 
retail  properties  contained  within  our  database.  If  we  are  unable  to  manage  this  expansion  effectively,  if  this 
expansion  effort  takes  longer  than  planned  or  if  our  costs  for  this  effort  exceed  our  expectations,  our  financial 
position could be adversely affected. In addition, if we incur significant costs to expand our retail sector services and 
we  are  not  successful  in  marketing  and  selling  these  expanded  services,  or  customers  fail  to  accept  these  new 
services,  our  expansion  may  have  a  material  adverse  effect  on  our  financial  position  by  increasing  our  expenses 
without increasing our revenues, adversely affecting our profitability. 

International expansion may result in new business risks, which may reduce our profitability. Our international 
operations  and  expansion  could  subject  us  to  new  business  risks,  including:  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.;  currency 
exchange rate fluctuations; 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 growth successfully, we may incur 
higher expenses and our profitability may be reduced. Finally, the investment required for international expansion 
could exceed the profit generated from such expansion, which would reduce our profitability and adversely affect 
our financial position.  

Competition  could  render  our  services  uncompetitive.  The  market  for  information  systems  and  services  in 
general  is  highly  competitive  and  rapidly  changing.  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, distribution partners and content providers or may be able 
to respond more quickly to new or emerging technologies or changes in user requirements. Increased competition 
could result in lower revenues and higher expenses, which would reduce our profitability. 

We may not be able to successfully introduce new or upgraded information services, which could decrease our 
revenues and our profitability. Our future business and financial success will depend on our ability to continue to 
introduce new and upgraded services into the marketplace. To be successful, we must adapt to rapid technological 
changes  by  continually  enhancing  our  information  services.  Developing  new  services  and  upgrades  to  services 
imposes  heavy  burdens  on  our  systems  department,  management  and  researchers.  This  process  is  costly,  and  we 
cannot assure you that we will be able to successfully develop and enhance our services. In addition, successfully 
launching and selling a new service puts pressure on our sales and marketing resources. If we are unable to develop 
new or upgraded services, then our customers may choose a competitive service over ours and our revenues may 
decline  and  our  profitability  may  be  reduced.  In  addition,  if  we  incur  significant  costs  in  developing  new  or 
upgraded services, are not successful in marketing and selling these new services or upgrades, or our customers fail 
to accept these new services, it could have a material adverse effect on our results of operations by decreasing our 
revenues or our revenue growth rate and reducing our profitability. 

If  we  are  not  able  to  successfully  identify  and  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. In addition, acquisitions involve numerous risks, including managing the integration 
of personnel and products; managing geographically remote operations, such as SPN in Scotland, Grecam S.A.S. in 
France, and Property Investment Exchange Limited in the U.K.; the diversion of management’s attention from other 
business concerns; 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 or clients of the acquired companies. We may not successfully 
integrate any acquired businesses or assets and may not achieve anticipated benefits of any acquisition. 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. 

Technical  problems  that  affect  either  our  customers’  ability  to  access  our  services,  or  the  software,  internal 
applications and systems underlying our services, could lead to reduced demand for our information services, lower 

16 

 
 
 
 
 
revenues and increased costs. Our business increasingly depends upon the satisfactory performance, reliability and 
availability  of  our  website,  the  internet  and  our  service  providers.  Problems  with  our  website,  the  internet  or  the 
services provided by our local exchange carriers or internet service providers could result in slower connections for 
our  customers  or  interfere  with  our  customers’  access  to  our  information  services.  If  we  experience  technical 
problems in distributing our services, we could experience reduced demand for our information services. In addition, 
the  software,  internal  applications  and  systems  underlying  our  services  are  complex  and  may  not  be  efficient  or 
error-free.  Despite  careful  development  and  testing,  we  cannot  be  certain  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 services, which could reduce the demand for our services, 
lower our revenues and increase our costs. 

Temporary or permanent outages of our computers, software or telecommunications equipment could lead to 
reduced demand for our information services, lower revenues and increased costs. Our operations depend on our 
ability to protect our database, computers and software, telecommunications equipment and facilities against damage 
from  potential  dangers  such  as  fire,  power  loss,  security  breaches,  computer  viruses  and  telecommunications 
failures. Any temporary or permanent loss of one or more of these systems or facilities from an accident, equipment 
malfunction or some other cause could harm our business. If we experience a failure that prevents us from delivering 
our  information  services  to  clients,  we  could  experience  reduced  demand  for  our  information  services,  lower 
revenues and increased costs. 

If  we  are  not  able  to  obtain  and  maintain  accurate,  comprehensive  or  reliable  data,  we  could  experience 
reduced  demand  for  our  information  services.  Our  success  depends  on  our  clients’  confidence  in  the 
comprehensiveness,  accuracy  and  reliability  of  the  data  we  provide.  The  task  of  establishing  and  maintaining 
accurate and reliable data is challenging. If our data, including the data we obtain from third parties, 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.  In  November  2006,  we  integrated  internal 
research  processes  that  our  U.S.  researchers  use  to  update  our  database.    Any  inefficiencies,  errors,  or  technical 
problems with this application could reduce the quality of our data, which could result in reduced demand for our 
services, lower revenues and higher costs.   

Our  stock  price  may  be  negatively  affected  by  fluctuations  in  our  financial  results.  Our  operating  results, 
revenues and expenses may fluctuate with general economic conditions and also for many other reasons, many of 
which are outside of our control, such as: cancellations or non-renewals of our services; competition; our ability to 
control expenses; loss of clients or revenues; technical problems with our services; changes or consolidation in the 
real estate industry; our investments in geographic expansion and to increase coverage in existing markets; interest 
rate fluctuations; the timing and success of new service introductions and enhancements; successful execution of our 
expansion plans; data quality; the development of our sales force; managerial execution; employee retention; foreign 
currency fluctuations; inflation; successful adoption of and training on our services; litigation; acquisitions of other 
companies  or  assets;  sales,  brand  enhancement  and  marketing  promotional  activities;  client  support  activities; 
changes  in  client  budgets;  or  our  investments  in  other  corporate  resources.  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. 

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:  quarter-to-quarter  variations  in  our  operating  results;  changes  in 
analysts’  estimates  of our  earnings;  announcements  by  us  or our  competitors  of  technological  innovations or new 
services; general conditions in the commercial real estate industry; developments or disputes concerning copyrights 
or proprietary rights or other legal proceedings; regulatory developments; and economic or other factors. In addition, 
in  recent  years,  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. 

17 

 
 
 
 
 
Fluctuating foreign currencies may negatively impact our business, results of operations and financial position. 
Due to our acquisitions of CoStar UK Limited (formerly FOCUS Information Limited), SPN, Grecam S.A.S. and 
Propex,  a  portion  of  our  business  is  denominated  in  the  British  Pound  and  Euro  and  as  a  result,  fluctuations  in 
foreign currencies may have an impact on our business, results of operations and financial position. Currencies may 
be  affected  by  internal  factors,  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  British  Pound  or  Euro  may  decrease  the  value  of  our  foreign  assets,  as  well  as  decrease  our  revenues  and 
earnings from our foreign subsidiaries. 

Negative  conditions  in  the  global  credit  markets  may  affect  the  liquidity  of  a  portion  of  our  short-term 
investments.  Currently our short-term investments include AAA rated auction rate securities, which are primarily 
securities  supported  by  guarantees  from  the  Federal  Family  Education  Loan  Program  (FFELP)  of  the  U.S. 
Department  of  Education.  Recent  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  February  22,  2008,  $29.1  million  of  the  $33.1 
million of our short-term investments in auction rate securities have failed to settle at auctions.  If the credit market 
does not improve, auctions for the remaining $4.0 million of our invested amounts may fail. When an auction fails 
for securities in which we have invested, we may be unable to liquidate some or all of our auction rate securities at 
par, should we need or desire to access the funds invested in those securities immediately. 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. 

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 the first quarter of 2006, we adopted the provisions 
of  SFAS  123R,  which  required  us  to  expense  the  value  of  granted  stock  options.  We  recorded  $2.9  million  in 
compensation charges for stock options in 2006. 

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

We  may  be  subject  to  legal  liability  for  displaying  or  distributing  information.  Because  the  content  in  our 
database is distributed to others, we may be subject to claims for defamation, negligence 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. 
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 services to users.

Properties 

Our corporate headquarters is located in Bethesda, Maryland, where we occupy approximately 73,500 square 
feet  of  office  space.  Our  main  lease  for  our  Bethesda,  Maryland  headquarters  expires  on  March  14,  2010.    This 
facility is used primarily by our U.S. segment. 

In addition to our Bethesda, Maryland facility, our research operations are principally run out of leased spaces 
in San Diego, California; Columbia, Maryland; White Marsh, Maryland; London, England; Glasgow, Scotland; and 
Paris, France. Additionally, we lease office space in a variety of other metropolitan areas, which generally house our 
field sales offices. These locations include, without limitation, the following: New York; Los Angeles; Chicago; San 
Francisco;  Boston;  Manchester,  England;  Orange  County,  California;  Philadelphia;  Houston;  Atlanta;  Phoenix; 
Detroit;  Pittsburgh;  Iselin,  New  Jersey;  Fort  Lauderdale;  Denver;  Dallas;  Kansas  City;  Cleveland;  Cincinnati; 
Tustin, California; Tampa; St. Louis; and Portland, Oregon.   

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

Item 3. 

Legal Proceedings 

On  May  8,  2007,  we filed  a  lawsuit  in  the  United  States  District  Court  for  the  District  of  Maryland  against 
Centers  &  Malls  LLC  and  two  individuals.   CoStar's  complaint  alleged  that  these  defendants  unlawfully  obtained 
part  of  CoStar's  proprietary  and  copyrighted  database  and  subsequently  sold  this  stolen  data  for  profit.  CoStar's 
complaint  sought  equitable  and  monetary  relief,  including  but  not  limited  to  a  permanent injunction  barring 
defendants from unlawful use of CoStar products and disgorgement to CoStar of ill-gotten gains.  Shortly after filing 
suit,  CoStar  obtained  a  temporary  restraining  order  barring  Centers  &  Malls  LLC  from  selling,  utilizing,  or 
distributing  its  products  that  were  pirated  from  CoStar's  database.    On  January  8,  2008,  the  parties  entered  into  a 
Settlement  Agreement  and  Mutual  Release,  pursuant  to  which  Centers  &  Malls  agreed,  among  other  things,  to 
permanently  shut  down  its  business  operations  and  pay  CoStar  monetary  damages,  in  full  release  of  all  claims 
against Centers & Malls and its employees.  In February 2008, a Stipulation for Entry of Judgment and Permanent 
Injunction was filed with the court and the complaint was dismissed.    

On  November  15,  2007,  LoopNet,  Inc.  (“LoopNet”)  filed  a  complaint  in  the  Superior  Court  of  the  State  of 
California  for  the  County  of  Los  Angeles  against  CoStar  and  certain  unnamed  John  Does  for  breach  of  contract, 
unfair  competition,  and  violation  of  California  Computer  Crime  Statute.    The  complaint  alleges  that  CoStar 
unlawfully copied and used LoopNet's data and seeks injunctive relief, compensatory damages, restitution and other 
costs (including attorneys’ fees) to be proven at trial.  LoopNet does not contend that anyone at CoStar has logged 
into  LoopNet’s  website  and  copied  listings,  nor  does  CoStar  believe  that  to  be  the  case.    Instead,  the  central 
contention of LoopNet’s lawsuit appears to be that it is unlawful for CoStar to use information provided to CoStar 
by  commercial  real  estate  brokers  and  property  owners  that:  (1)  type  in  their  own  listings  and  upload  their  own 
photos into either LoopNet’s listing service or LoopNet's software and web site hosting solution, LoopLink, and (2) 
use either the “email to a friend” function available within LoopNet’s service to send their listings for marketing on 
CoStar,  or  direct  CoStar  personnel  to  market  the  listings  that  appear  on  the  brokers'  or  owners'  websites.  This 
contention  is  presumably  based  on  the  assumption  that  LoopNet  controls  the  listings  created  by  commercial  real 
estate brokers and owners that use LoopNet and that LoopNet can prevent brokers and owners from marketing their 
own  listings  if  the  listings  also  appear  on  LoopNet's  listing  service  or  a  website  hosted  by  LoopLink.    CoStar 
believes that LoopNet’s claims are unfounded. 

CoStar  filed  its  Answer  and  several  claims  against  LoopNet  in  this  proceeding,  including  breach  of  contract, 
unfair competition and other claims.  We are seeking injunctive relief, restitution, pre-judgment interest, costs and 
disbursements, attorneys’ fees and direct, consequential, compensatory and punitive damages.  LoopNet has filed a 
motion to strike CoStar’s claims against LoopNet in this action.  

Were LoopNet to prevail in this lawsuit, we could be required to make payments and/or comply with injunctive 
relief,  including potentially  removal of  certain  listings, which  could  negatively  impact  our  business and  operating 
results.  Although no assurance can be given as to the outcome of this lawsuit, CoStar believes LoopNet's allegations 

19 

 
 
 
 
 
 
 
 
 
 
are without merit and intends to vigorously defend itself.   

On February 5, 2008, we filed a complaint in the United States District Court for the Southern District of New 
York against LoopNet for false advertising under Section 43(a) of the Lanham Act.  CoStar alleges that LoopNet has 
engaged in false advertising by making misleading statements to the marketplace about the number of people that 
use its website.  Specifically, CoStar believes, based on current statements made by LoopNet, that the 2.5 million 
registered users that LoopNet reports is not the number of current users, but rather the total cumulative number of 
user IDs created over the last decade or so and therefore includes user IDs that have not been used in years, and in 
some cases, multiple user IDs for the same person.  Our lawsuit alleges that LoopNet’s use of this 2.5 million figure 
to competitively market how many users it currently has is false and misleading. 

CoStar's complaint seeks injunctive relief and the maximum dollar amount permitted under the Lanham Act, as 

well as attorneys’ fees and costs.  LoopNet has not yet answered CoStar’s complaint.     

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 lawsuits or proceedings that, in the opinion of our management based on consultations with legal 
counsel, are 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. The following discussion should be read in conjunction with our Annual 
Reports on Form 10-K, 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  in  this  Annual 
Report on Form 10-K. 

Overview   

CoStar  is  the  leading  provider  of  information  services  to  the  commercial  real  estate  industry  in  the  United 
States  and  the  United  Kingdom  based  on  the  fact  that  we  offer  the  most  comprehensive  commercial  real  estate 
database available, have the largest research department in the industry, provide more information services than any 
of  our  competitors  and  believe  we  generate  more  revenues  than  any  of  our  competitors.  We  have  created  a 
standardized information platform where the members of the commercial real estate and related business community 
can continuously interact and facilitate transactions by efficiently exchanging accurate and standardized commercial 
real estate information. Our integrated suite of online service offerings includes information about space available 
for  lease,  comparable  sales  information,  tenant  information,  information  about  properties  for sale,  information  for 
clients'  websites,  information  about  industry  professionals  and  their  business  relationships,  analytic  information, 
data integration, property marketing and industry news. Our service offerings span all commercial property types - 
office, industrial, retail, land, mixed-use, hospitality and multifamily. 

Since  1994,  we  have  expanded  the  geographical  coverage  of  our  existing  information  services  and  developed 
new  information  services.  In  addition  to  internal  growth,  this  expansion  included  the  acquisitions  of  Chicago 
ReSource,  Inc.  in  Chicago  in  1996  and New  Market  Systems,  Inc.  in  San Francisco  in 1997. In August  1998, we 
expanded into the Houston region through the acquisition of Houston-based real estate information provider C Data 
Services, Inc. In January 1999, we expanded further into the Midwest and Florida by acquiring LeaseTrend, Inc. and 
into  Atlanta  and  Dallas/Fort Worth  by  acquiring  Jamison  Research,  Inc.  In  February  2000,  we  acquired 
COMPS.COM,  Inc.,  a  San Diego-based  provider  of  commercial  real  estate  information.  In  November  2000,  we 
acquired First Image Technologies, Inc. In September 2002, we expanded further into Portland, Oregon through the 
acquisition of certain assets of Napier Realty Advisors d/b/a REAL-NET. In January 2003, we established a base in 
the  U.K.  with  our  acquisition  of  London-based  FOCUS  Information  Limited.  In  May  2004,  we  expanded  into 
Tennessee through the acquisition of Peer Market Research, Inc., and in September 2004, we extended our coverage 
of the U.K. through the acquisition of Scottish Property Network. In September 2004, we strengthened our position 
in Denver, Colorado through the acquisition of substantially all of the assets of RealComp, Inc., a local comparable 
sales  information  provider.  In  January  2005,  we  acquired  National  Research  Bureau,  a  leading  provider  of 
U.S. shopping center information. Additionally, in December 2006, our U.K. subsidiary, CoStar Limited, acquired 
Grecam  S.A.S.  (“Grecam”),  a  provider of  commercial  property  information  and  market-level  surveys,  studies  and 
consulting  services  located  in  Paris,  France.  In  February  2007,  CoStar Limited  also  acquired Property  Investment 
Exchange Limited (“Propex”), a provider of commercial property information and operator of an online investment 
property exchange located in London, England. The more recent acquisitions are discussed later in this section under 
the heading “Recent Acquisitions.” 

In 2004, we began our expansion into 21 new metropolitan markets throughout the U.S., as well as expanding 
the geographical coverage of many of our existing U.S. and U.K. markets. In the first quarter of 2006, our expansion 
into the 21 new markets was complete.   

24 

 
 
 
 
 
  
 
In early 2005, we announced the launch of a major effort to expand our coverage of retail real estate information. 
The new retail component of our flagship product, CoStar Property Professional, was unveiled in May 2006 at the 
International Council of Shopping Centers’ convention in Las Vegas. 

During  the  second  half  of  2006,  we  began  actively  researching  commercial  properties  in  81  new  Core  Based 
Statistical  Areas  (“CBSAs”)  in  the  U.S.,  increased  our  U.S.  field  research  fleet  by  adding  89  vehicles  and  hired 
researchers to staff these vehicles. In March 2007, we signed a long-term lease for a new research facility in White 
Marsh, Maryland, in support of our expanded research efforts and hired and trained additional researchers and other 
personnel. We released our CoStar Property Professional service in the 81 new CBSAs across the U.S. in the fourth 
quarter of 2007 in an effort to further expand the geographical coverage of our service offerings, including our retail 
service. 

We believe that there is opportunity to capture potential revenue from prospective customers for our service in 
our current markets. We have restructured and expanded our field sales force in the U.S. to take advantage of this 
market opportunity. In the fourth quarter of 2006, we began rapidly expanding the size of our sales force and have 
since  doubled  its  size.  Sales  representatives  with  less  than  a  year  of  experience  tend  to  be  less  productive  than 
representatives with more than a year of experience. We expect that productivity per sales person will increase over 
the next year.  

In  connection  with  our  recent  acquisitions  of  Propex  and  Grecam,  we  intend  to  expand  the  coverage  of  our 
service  offerings  within  the  U.K.,  integrate  our  international  operations  more  fully  with  those  of  the  U.S., and 
eventually to introduce a consistent international platform of service offerings. We recently introduced the CoStar 
Group as the “brand” encompassing our international operations. 

To cost effectively manage the growth of our international operations, we opened a research operations center in 
Glasgow, Scotland in 2007, rather than expand our operations in London. During the third quarter of 2007, we took 
steps to consolidate and streamline our international operations. As a result of these steps, certain management and 
staff  positions  in  the  U.K.  were  made  redundant,  which  reduced  certain  costs  and  the  amount  of  office  space 
required  in  London.  On  September  14,  2007,  CoStar  UK  Limited,  a  wholly  owned  U.K.  subsidiary  of  CoStar, 
entered into an agreement to assign the leasehold for our London office in Mayfair. Effective December 19, 2007, 
CoStar UK Limited assigned its lease interest in that office space in exchange for a payment of $7.6 million, net of 
expenses. We consolidated our London offices in Mayfair and Sheen into one facility in central London. We expect 
to gain operational efficiencies as a result of consolidating a majority of our U.K. research operations in one location 
in Glasgow and combining the majority of our remaining U.K. operations in one central location in London. 

Our expansion into 81 new CBSAs, expansion of our coverage in existing markets, sales force expansion and 
expansion and integration of our international operations has caused our costs in 2007 to escalate over costs in 2006. 
However,  as  we  complete  these  initiatives  and  the  related  costs  stabilize,  we  believe  they  will  facilitate  the 
generation  of  additional  revenue  and  provide  a  platform  for  earnings  growth.  Our  2007  results  reflect  growth  in 
earnings as a result of these investments in our business, and we expect revenues to continue to grow over what is 
now a relatively fixed cost base for our U.S. research operations. 

Although we do not currently plan to initiate new significant investments through 2008, we expect to continue to 
develop  and  distribute  new  services,  expand  existing  services  within  our  current  platform,  consider  strategic 
acquisitions and expand and develop our sales and marketing organization. Any future expansion could reduce our 
profitability and increase our capital expenditures. Therefore, while we expect current service offerings in to remain 
profitable, driving overall earnings growth throughout 2008 and providing substantial cash flow for our business, it 
is possible that any new investments could cause us to generate losses and negative cash flow from operations in the 
future. 

We  expect  2008  revenue  to  grow  over  2007  revenue  as  a  result  of  further  penetration  of  our  services  in  our 
potential customer base across our platform, successful cross selling of our services to our existing customer base, 
continued  depth  of  coverage  and  acquisitions.  We  expect  that  2008  EBITDA,  which  is  our  net  income  before 
interest, income taxes, depreciation and amortization, will increase over 2007 based on the growth in EBITDA from 
U.S.  operations.  We  anticipate  that  our  EBITDA  for  our  existing  core  U.S.  platform  will  continue  to  grow 

25 

 
 
 
 
 
 
  
principally due to growth in revenue. We believe the company is well positioned to generate continued, sustained 
earnings through the end of 2008. 

We currently issue restricted stock and stock options to our officers, directors and employees, and as a result we 
record additional compensation expense in our consolidated statements of operations. We plan to continue the use of 
alternative  stock-based  compensation  for  our  officers,  directors  and  employees,  which  may  include,  among  other 
things,  restricted  stock  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.  We  incurred  approximately 
$5.4 million in total equity compensation expense in 2007. 

Our  subscription-based  information  services,  consisting  primarily  of  CoStar  Property  Professional,  CoStar 
Tenant, CoStar COMPS Professional, FOCUS services and Propex services currently generate approximately 95% 
of our total revenues. Our contracts for our subscription-based information services typically have a minimum term 
of  one  year  and  renew  automatically.  Upon  renewal,  many  of  the  subscription  contract  rates  may  increase  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 fees based on 
actual system usage. Contract rates are based on the number of sites, number of users, organization size, the client’s 
business  focus,  geography  and  the  number  of  services  to  which  a  client  subscribes.  Our  subscription  clients 
generally pay contract fees on a monthly basis, but in some cases may  pay us on a quarterly or annual basis. We 
recognize this 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 years ended December 31, 2006 and 2007, our contract renewal rate was over 90%. 

Application of Critical Accounting Policies and Estimates 

The preparation of financial statements and related disclosures in conformity with generally accepted accounting 
principles (“GAAP”) in the United States of America, 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 
estimates  reasonably  could have been used  in  the  current  period.  Changes  in  the  accounting  estimates  we  use  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. 

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 the Company relate to 
the expected useful lives of long-lived assets and its ability to realize any undiscounted cash flows of the carrying 
amounts of such assets and are affected by 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 measure any impairment based on a projected 
discounted cash flow method using a discount rate determined by our management to be commensurate with the risk 
inherent in our current business model. 

26 

 
  
 
 
 
 
 
 
 
 
Goodwill and identifiable intangible assets not subject to amortization are tested annually by operating segment 
on October 1st of each year for impairment and are tested for impairment more frequently based upon the existence 
of one or more of the above indicators. We measure any impairment loss to the extent that the carrying amount of 
the asset exceeds its fair value. 

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 actual 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  statements  of 
operations.  

At  December  31,  2007,  we  had  net  operating  loss  carryforwards  for  federal  income  tax  purposes  of 

approximately $14.9 million, which we expect to use during 2008. 

As a result, we expect cash payments for taxes during 2008 of approximately $12.0 million because our U.S. 
taxable income will no longer be absorbed by carryforward losses.  Our U.K. operations are expected to generate net 
operating losses for the full year 2008.  Losses in the U.K. will generate a lower tax benefit than if the costs were 
incurred in the U.S., thereby creating a higher effective tax rate in 2008. 

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. Currently, the non-GAAP 
financial  measure  that  we  disclose  is  EBITDA,  which  is  our  net  income  (loss)  before  interest,  income  taxes, 
depreciation and amortization. We disclose EBITDA 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  more  meaningfully  evaluate  and  compare  our  future 
results of operations to our previously reported results of operations. 

We  view  EBITDA  as  an  operating  performance  measure  and  as  such  we  believe  that  the  GAAP  financial 
measure most directly comparable to it is net income (loss). In calculating EBITDA, 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 is not a measurement 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 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 reconciliation of EBITDA to net income (loss) set forth 
below, in our earnings releases and in other filings with the Securities and Exchange Commission and to carefully 
review  the  GAAP  financial  information  included  as  part  of  our  Quarterly  Reports  on  Form 10-Q  and  our  Annual 
Reports on Form 10-K 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. 

EBITDA  is  used  by  management  to  internally  measure  our  operating  and  management  performance  and  by 
investors as a supplemental financial measure to evaluate the performance of our business that, when viewed with 
our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to 
gain an understanding of the factors and trends affecting our business. We have spent more than 20 years building 

27 

 
 
 
 
 
 
 
 
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  services,  which  included 
acquisitions, our net income (loss) has included significant charges for purchase amortization, depreciation and other 
amortization.  EBITDA  excludes  these  charges  and  provides  meaningful  information  about  the  operating 
performance of our business, apart from charges for purchase amortization, depreciation and other amortization. We 
believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our performance from quarter 
to  quarter  and  from  year  to  year.  We  also  believe  EBITDA  is  a  measure  of  our  ongoing  operating  performance 
because the isolation of non-cash charges, such as amortization and depreciation, and non-operating items, such as 
interest and income taxes, 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 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 
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  and  the  diminishing  value  of  any  acquired  trade 
names. 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 net interest income we generate may be useful for investors to consider and may result in 
current cash inflows or outflows. However, we do not consider the amount of net interest income to be a 
representative component of the day-to-day operating performance of our business. 

• 

Income  tax  expense  (benefit) 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 (benefit) to be a representative component of the day-to-day operating 
performance of our business.   

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 gain an 
understanding of the factors and trends affecting our business.

Comparison of Year Ended December 31, 2007 and Year Ended December 31, 2006 

Revenues.  Revenues  grew  21.3%  to  $192.8  million  in  2007,  from  $158.9  million  in  2006.  This  increase  in 
revenue  has  resulted  from  continued  penetration  of  our  subscription-based  information  services,  the  successful 
cross-selling  of  additional  products  and  services  to  our  existing  customer  base  combined  with  a  continued  high 
renewal rate, and additional revenues from acquired companies, including Grecam, acquired in December 2006, and 
Propex,  acquired  in  February  2007.  Our  subscription-based  information  services  consist  primarily  of  CoStar 

29 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
   
 
   
 
 
   
 
   
 
 
 
 
   
 
   
 
 
 
   
 
 
 
   
 
 
 
   
 
 
   
 
   
 
 
   
 
 
   
 
 
 
   
 
 
 
 
Property  Professional,  CoStar  Tenant,  CoStar  COMPS  Professional,  FOCUS  services  and  Propex  services.  As  of 
December  31,  2007,  our  subscription-based  information  services  represented  approximately  95%  of  our  total 
revenues.  

Gross  Margin.  Gross  margin  increased  to  $116.1  million  in  2007,  from  $102.8  million  in  2006.  The  gross 
margin  percentage  decreased  to  60.2%  in  2007,  from  64.7%  in  2006.  The  increase  in  the  gross  margin  amount 
resulted  principally  from  revenue  growth  from  our  subscription-based  information  services,  partially  offset  by  an 
increase in cost of revenues. The decrease in gross margin percentage was principally due to an increase in the cost 
of revenues to $76.7 million for 2007, from $56.1 million for 2006. The increase in cost of revenues resulted from 
increased  research  department  hiring,  training,  compensation  and  other  operating  costs,  principally  in  connection 
with our retail and 81 new CBSA expansions, and our international expansion, as well as increased cost structures 
associated with the acquisitions of Grecam and Propex. 

Selling and Marketing Expenses. Selling and marketing expenses increased to $51.8 million in 2007, from $41.8 
million in 2006, and increased as a percentage of revenues to 26.9% in 2007, from 26.3% in 2006. The increase in 
the  amount  of  selling  and  marketing  expenses  is  primarily  due  to  increased  growth  in  the  sales  force,  increased 
marketing efforts, as well as increased cost structures associated with the acquisition of Propex.  

Software Development Expenses. Software development expenses increased to $12.5 million in 2007, from $12.0 
million in 2006, and decreased as a percentage of revenues to 6.5% in 2007, from 7.6% in 2006. The increase in the 
amount  of  software  development  expenses  was  primarily  due  to  increased  costs  associated  with  the  continued 
development of an international platform. The decrease in the percentage was primarily due to our continued efforts 
to control and leverage our costs. 

General and Administrative Expenses. General and administrative expenses increased to $36.6 million in 2007, 
from  $30.7 million  in 2006,  and decreased  slightly  as  a  percentage  of  revenues  to  19.0%  in  2007,  from  19.3%  in 
2006.  The  increase  primarily  includes  increases  in  personnel  expenses,  cost  structures  associated  with  the 
acquisition of Propex and equity compensation.   

Gain  on  Lease  Settlement,  Net.  On  September  14,  2007,  CoStar  Limited,  a  wholly  owned  U.K.  subsidiary  of 
CoStar, entered into an agreement with Trafigura Limited to assign to Trafigura our leasehold interest in the office 
space located in London. The lease assignment was effective on December 19, 2007. As a result, CoStar U.K. was 
paid $7.6 million, net of expenses, for the assignment of the lease. There were no gains on lease settlements in 2006.   

Purchase Amortization. Purchase amortization increased to $5.1 million in 2007, from $4.2 million in 2006, and 
remained consistent as a percentage of revenues at 2.6% in 2007 and 2006. This increase in the amount was due to 
the acquisitions of Grecam and Propex. 

Interest  and  Other  Income,  Net.  Interest  and  other  income,  net  increased  to  $8.0  million  in  2007,  from  $6.8 
million  in  2006.  This  increase  was  primarily  due  to  higher  interest  income  as  a  result  of  higher  total  short-term 
investment balances for 2007 and increased interest rates for 2007 as compared to 2006.  

Income Tax Expense, Net. Income tax expense, net increased to $9.9 million in 2007, from $8.5 million in 2006. 
This increase was due to higher income before income taxes for 2007, partially offset by a lower effective tax rate.  
The  effective  tax  rate  was  lower  in  2007  due  to  the  gain  on  lease  settlement  in  the  U.K.  that  was  completed  in 
December 2007.  The lease settlement resulted in income in the U.K., which reduced the overall effective tax rate. 

Comparison of Business Segment Results for Year Ended December 31, 2007 and Year Ended December 31, 
2006 

Due to the increased size, complexity and funding requirements associated with our international expansion, in 
2007  we  began  to  manage  our  business  geographically  in  two  operating  segments,  with  our  primary  areas  of 
measurement  and  decision-making  being  the  U.S.  and  International,  which  includes  the  U.K.  and  France. 
Management  relies  on  an  internal  management  reporting  process  that  provides  revenue  and  segment  EBITDA, 
which  is  our  net  income  before  interest,  income  taxes,  depreciation  and  amortization.  Management  believes  that 
segment EBITDA is an appropriate measure for evaluating the operational performance of our segments. EBITDA 

30 

 
 
 
 
 
 
 
 
 
 
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.  U.S.  revenues  increased  to  $170.3  million  from  $146.1  million  for  the  years  ended 
December 31, 2007 and 2006, respectively. This increase in U.S. revenue is due to further penetration of our U.S. 
subscription-based information services and the successful cross-selling into our customer base across our service 
platform  in  existing  markets,  combined  with  a  continued  high  renewal  rate.  International  revenues  increased  to 
$22.5 million from $12.8 million for the years ended December 31, 2007 and 2006, respectively. This increase in 
international  revenue  is  principally  a  result  of  a  combination  of  further  penetration  of  our  subscription-based 
information services in the U.K. and the acquisitions of Grecam and Propex.  

Segment EBITDA. U.S. EBITDA increased to $32.9 million from $26.2 million for the years ended December 
31, 2007 and 2006, respectively. The increase in U.S. EBITDA was due to increased revenues, partially offset by 
increased research costs and growth in our sales force as a result of our expansion. International EBITDA increased 
to $1.1 million from a loss of $315,000 for the years ended December 31, 2007 and 2006, respectively. This increase 
is  primarily  due  to  the  assignment  of  our  lease  to  Trafigura,  offset  by  our  increased  investment  in  international 
expansion.  International  EBITDA  also  includes  a  corporate  allocation  of  approximately  $2.6  million  and  $1.0 
million  for  the  years  ended  December  31,  2007  and  2006,  respectively.  The  corporate  allocation  represents  costs 
incurred for U.S. employees involved in international management and expansion activities. 

Comparison of Year Ended December 31, 2006 and Year Ended December 31, 2005 

Revenues.  Revenues  grew  18.3%  to  $158.9  million  in  2006,  from  $134.3  million  in  2005.  This  increase  in 
revenue  is  principally  due  to  further  penetration  of  our  subscription-based  information  services,  as  well  as  the 
successful  cross  selling  to  our  customer  base  across  our  service  platform  in  existing  markets  combined  with 
continued  high  renewal  rates.  Our  subscription-based  information  services  consist  primarily  of  CoStar  Property 
Professional,  CoStar  Tenant,  CoStar  COMPS  Professional  and  FOCUS  services.  As  of  December  31,  2006,  our 
subscription-based information services represented 96% of our total revenues.  

Gross  Margin.  Gross  margin  increased  to $102.8  million  in  2006,  from  $90.1  million  in  2005. Gross  margin 
percentage  decreased  to  64.7%  in  2006,  from  67.0%  in  2005.  The  increase  in  the  gross  margin  amount  resulted 
principally  from  internal  revenue  growth  from  our  subscription-based  information  services,  partially  offset  by  an 
increase  in  cost  of  revenues.  Cost  of  revenues  increased  to  $56.1  million  in  2006,  from  $44.3  million  in  2005, 
principally  due  to  increased  research  department  hiring,  training,  compensation  and  other  operating  costs  and  the 
addition of offshore resources from our geographic and retail expansion, as well as research costs associated with 
further service enhancements to our existing platform.   

Selling  and  Marketing  Expenses.  Selling  and  marketing  expenses  increased  to  $41.8  million  in  2006,  from 
$38.4  million  in  2005  and  decreased  as  a  percentage  of  revenues  to  26.3%  in  2006,  from  28.6%  in  2005.  The 
increase  in  the  amount  of  selling  and  marketing  expenses  is  primarily  due  to  sales  and  marketing  efforts  for  our 
current retail and geographic expansion plan as well as costs associated with growth in the sales force.  Additionally, 
stock-based  compensation  expense,  due  to  the  implementation  of  SFAS  123R,  included  in  selling  and  marketing 
expenses for the year ended December 31, 2006, was $1.3 million compared to approximately $19,000 for the year 
ended December 31, 2005. 

Software  Development  Expenses.  Software  development  expenses  increased  to  $12.0  million  in  2006,  from 
$10.1 million in 2005 and remained relatively consistent as a percentage of revenues to 7.6% in 2006, from 7.5% in 
2005. The majority of the increase in the amount of software and development expense was due to the hiring of new 
employees to support our continued focus on enhancements to our existing services, development of new services 
and development costs for our internal information systems.  

General and Administrative Expenses. General and administrative expenses increased to $30.7 million in 2006, 
from $27.6 million in 2005 and decreased as a percentage of revenues to 19.3% in 2006, from 20.5% in 2005. The 
increase  in  the  amount  of  general  and  administrative  expenses  was  primarily  due  to  an  increase  in  stock-based 

31 

 
 
 
 
 
 
 
 
compensation, due to the implementation of SFAS 123R, to $2.4 million in 2006, from $290,000 for the year ended 
2005 and an increase in professional services. 

Restructuring  Charge.  We  did  not  incur  any  restructuring  charges  in  2006.    In  the  third  quarter  of  2005,  we 
recorded a restructuring charge of approximately $2.2 million in connection with the closing of our research center 
in Mason, Ohio.  The restructuring charge included amounts for wages, severance, occupancy and other costs. 

Purchase  Amortization.  Purchase  amortization  decreased  to  $4.2  million  in  2006,  from  $4.5  million  in  2005. 

This decrease was due to the completion of amortization for certain identifiable intangible assets during 2006. 

Interest  and  Other  Income,  Net.    Interest  and  other  income,  net  increased  to  $6.8  million  in  2006,  from  $3.5 
million in 2005. This increase was primarily a result of higher total cash, cash equivalents and short-term investment 
balances and increased interest rates during the year. 

Income  Tax  Expense,  Net.    Income  tax  expense,  net  increased  to  $8.5  million  in  2006,  from  $4.3  million  in 

2005, as a result of our increased profitability. 

Comparison of Business Segment Results for Year Ended December 31, 2006 and Year Ended December 31, 
2005 

Segment  Revenues.  U.S.  revenues  increased  to  $146.1  million  from  $123.4  million  for  the  years  ended 
December 31, 2006 and 2005, respectively. This increase in U.S. revenue is due to further penetration of our U.S. 
subscription-based information services and the successful cross-selling into our customer base across our service 
platform  in  existing  markets,  combined  with  a  continued  high  renewal  rate.  International  revenues  increased  to 
$12.8 million from $11.0 million for the years ended December 31, 2006 and 2005, respectively. This increase in 
international  revenue  is  principally  a  result  of  a  combination  of  further  penetration  of  our  subscription-based 
information services and the acquisition of Grecam.  

Segment EBITDA. U.S. EBITDA increased to $26.2 million from $19.4 million for the years ended December 
31, 2006 and 2005, respectively. The increase in U.S. EBITDA was due to increased revenues, partially offset by 
increased  research  costs  as  a  result  of  our  geographic  and  retail  expansion.  International  EBITDA  remained 
consistent  as  a  loss  of  $315,000  and  a  loss  of  $316,000  for  the  years  ended  December  31,  2006  and  2005, 
respectively.  This  loss  is  due  to  our  increased  investment  in  international  expansion.  International  EBITDA  also 
included a corporate allocation of approximately $1.0 million for each of the years ended December 31, 2006 and 
2005. The corporate allocation represents costs incurred for U.S. employees involved in international management 
and expansion activities.

Recent Acquisitions 

Grecam. S.A.S. On December 21, 2006, CoStar Limited, a wholly owned subsidiary of CoStar, acquired Grecam 
S.A.S. (“Grecam”), a provider of commercial property information and market-level surveys, studies and consulting 
services  located  in  Paris,  France.  CoStar  Limited  acquired  all  of  the  outstanding  capital  stock  of  Grecam  for 
approximately $2.0 million in cash.  

Propex. On February 16, 2007, CoStar Limited acquired Property Investment Exchange Limited (“Propex”), a 
provider  of web-based  commercial  property  information  and  operator  of  an  electronic platform  that  facilitates  the 
exchange of investment property in the U.K. Propex’s suite of electronic platforms and listing websites give users 
access  to  the  U.K.  commercial  property  investment  and  leasing  markets.  CoStar  Limited  acquired  all  outstanding 
capital stock of Propex for approximately $22.0 million, consisting of cash, deferred consideration of approximately 
$2.9 million, and 21,526 shares of CoStar common stock. 

Accounting Treatment. These acquisitions were accounted for using purchase accounting. The purchase price for 
each acquisition was primarily allocated to acquired database technology, customer base, trade names, and goodwill. 
The acquired database technology is being amortized on a straight-line basis over four years. The acquired customer 
base  for  the  acquisitions,  which  consists  of  one  distinct  intangible  asset  for  each  acquisition  and  is  composed  of 
acquired customer contracts and the related customer relationships, is being amortized on a 125% declining balance

method over ten years. The Grecam and Propex acquired trade names are being amortized on a straight-line basis 
over three years. Goodwill is not amortized, but is subject to annual impairment tests. The results of operations of 
Grecam and Propex have been consolidated with those of the Company since the respective dates of the acquisitions 
and  are  not  considered  material to  the  consolidated  financial  statements  of  the  Company.  Accordingly, pro  forma 
financial information has not been presented for either acquisition. 

Liquidity and Capital Resources 

Our  principal  sources  of  liquidity  are  cash,  cash  equivalents  and  short-term  investments.  Total  cash,  cash 
equivalents and short-term investments were $187.4 million at December 31, 2007 compared to $158.1 million at 
December 31, 2006. Cash, cash equivalents and short-term investments increased principally as a result of EBITDA, 
interest  income,  and  proceeds  from  exercise  of  stock  options,  partially  offset  by  purchases  of  property  and 
equipment  and  other  assets,  cash  used  for  the  purchase  of  Propex  for  approximately  $16.7  million,  capital 
expenditures and changes in working capital accounts.  

Net cash provided by operating activities for the year ended December 31, 2007 was $51.8 million compared to 
$32.8 million for the year ended December 31, 2006. The $19.0 million increase in net cash provided by operating 
activities  is  primarily  due  to  increased  earnings  before  non-cash  charges  for  taxes,  stock  based  compensation, 
provision for losses on accounts receivable, depreciation and amortization, and the $7.6 million net gain from lease 
settlement, partially offset by the net effect of changes in working capital. 

Net  cash  used  in  investing  activities  was  $40.4  million  for  the  year  ended  December  31,  2007  compared  to 
$28.5  million  for  the  year  ended  December  31,  2006.  This  $11.9  million  increase  in  net  cash  used  in  investing 
activities  was  due  to  the  acquisition  of  Propex  for  approximately  $16.7  million,  net  of  acquired  cash,  increased 
purchases of short-term investments and increased purchases of property and equipment. 

Net cash provided by financing activities was $8.2 million for the year ended December 31, 2007 compared to 
$5.6 million for the year ended December 31, 2006.  The higher net cash produced by financing activities in 2007 
compared to 2006 is due to an increase in proceeds from the exercise of stock options. 

Contractual Obligations. The following table summarizes our principal contractual obligations at December 31, 
2007  and  the  effect  such  obligations  are  expected  to  have  on  our  liquidity  and  cash  flows  in  future  periods  (in 
thousands):

(1)Amounts do not include current purchase obligations that may be renewed on the same or different terms or terminated by 
us or a third party. 

During 2007, we incurred capital expenditures of approximately $14.3 million, including expenditures related to 
our  expansion,  support  for  our  existing  operations  as  well  as  building  photography.  We  expect  to  make  capital 
expenditures  in  2008  of  approximately  $8.0  million  to  $9.0  million,  including  investments  in  facilities,  building 
photography, network equipment and workstations to support ongoing operations.  

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 expect to use cash, stock, debt or 
other means of funding to make these acquisitions. 

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 February 22, 2008, we had $33.1 million of short-term investments in student loan auction rate securities 
and $29.1 million of these securities failed to settle at auctions.  These investments are of high credit quality with 
AAA credit ratings and are primarily securities supported by guarantees from the Federal Family Education Loan 
Program (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, cash equivalents 
and other short-term investments 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. 

At  December  31,  2007,  we  had  net  operating  loss  carryforwards  for  federal  income  tax  purposes  of 
approximately $14.9 million, which we expect to use during 2008.  As a result, we expect our cash payments for 
taxes to be approximately $12.0 million during 2008 because our U.S. taxable income will no longer be absorbed by 
carryforward losses. 

Inflation may affect the way we operate in the U.S. and abroad. In general, we believe that over time we are 
able to increase the prices of our services to counteract the majority of the inflationary effects of increasing costs.  
We  do  not  believe  the  impact  of  inflation  has  significantly  affected  our  operations,  and  we  do  not  anticipate  that 
inflation will have a material impact on our operations in 2008. 

Recent Accounting Pronouncements 

In  June  2006,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  FASB  Interpretation  No.  48 
“Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109” (“FIN 48”), which 
became effective for our company as of January 1, 2007. FIN 48 addresses the determination of how tax benefits 
claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FIN 48, we 
must recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the tax position 
will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax 
benefits recognized in the financial statements from such a position are measured based on the largest benefit that 
has a greater than fifty percent likelihood of being realized upon ultimate resolution. Our reassessment of our tax 
positions  in  accordance  with  FIN  48  did  not  have  a  material  impact  on  our  results  of  operations  and  financial 
position. 

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”), which defines 
fair  value,  establishes  a  framework  for  measuring  fair  value  in  accordance  with  GAAP  and  expands  disclosures 
about fair value measurements. SFAS 157 does not require any new fair value measurements under GAAP and is 
effective  for  fiscal  years  beginning  after  November 15,  2007. The  effects  of  adoption  will  be  determined  by  the 
types of instruments carried at fair value in our financial statements at the time of adoption as well as the method 
utilized to determine their fair values prior to adoption. The adoption of SFAS 157 is not expected to have a material 
effect on our results of operations or financial position.   

In  February  2007,  the  FASB  issued  SFAS No. 159,  “Fair  Value  Option  for  Financial  Assets  and  Financial 
Liabilities — Including an amendment of FASB Statement No. 115” (“SFAS 159”), which permits entities to choose 
to measure many financial instruments and certain other items at fair value. SFAS 159 is effective for fiscal years 
beginning on or after December 31, 2007. We have assessed the provisions of SFAS 159 and determined that it is 
not expected to have a material effect on our results of operations or financial position. 

 In December 2007, the FASB issued SFAS No. 141 (Revised 2007), “Business Combinations” (“SFAS 141R”), 
which  will  change  the  accounting  for  any  business  combination  we  enter  into  with  an  acquisition  date  after 
December 31, 2008. Under SFAS 141R, an acquiring entity will be required to recognize all the assets acquired and 
liabilities assumed in a transaction at the acquisition date fair value with limited exceptions. SFAS 141R will change 
the accounting treatment and disclosure for certain specific items in a business combination. SFAS 141R will have 
an impact on accounting for business combinations once adopted but its effect will be dependent upon the specifics 
of any business combination with an acquisition date subsequent to the date of adoption. 

In  December 2007,  the  FASB  issued  SFAS  No. 160,  “Noncontrolling  Interests  in  Consolidated  Financial 
Statements—An  Amendment  of  ARB  No. 51”  (“SFAS  160”),  which  establishes  new  accounting  and  reporting 

35 

 
 
 
 
 
 
 
 
standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 is 
effective for fiscal years beginning on or after December 15, 2008. The adoption of SFAS 160 is not expected to 
have a material impact on our results of operations or financial position. 

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk  

We provide information services to the commercial real estate and related business community in the U.S., the 
U.K. and France. Our functional currency for our operations in the U.K. and France is the local currency. As such, 
fluctuations in the British Pound and Euro may have an impact on our business, results of operations and financial 
position.  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,  2007,  accumulated other  comprehensive  income  (loss)  included  a gain  from 
foreign currency translation adjustments of approximately $5.5 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, 2007. 

Included within our short-term investments are investments in AAA rated student loan auction rate securities.  
These securities are primarily securities supported by guarantees from the Federal Family Education Loan Program 
(FFELP)  of  the  U.S.  Department  of  Education.    As  of  February  22,  2008,  auctions  for  $29.1  million  of  our 
investments in auction rate securities failed.  As a result, we may not be able to sell these investments at par value 
until  a  future  auction  on  these  investments  is  successful.  In  the  event  we  need  to  immediately  liquidate  these 
investments,  we  may  have  to  locate  a  buyer  outside  the  auction  process,  who  may  be  unwilling  to  purchase  the 
investments at par, resulting in a loss.  If the issuers are unable to successfully close future auctions and their credit 
ratings  deteriorate,  we  may  be  required  to  adjust  the  carrying  value  of  these  investments  through  an  impairment 
charge.  Based on our ability to access our cash, cash equivalents and other short-term investments, 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 Note 2 to the consolidated financial statements for further discussion. 

We  have  a  substantial  amount  of  intangible  assets.  Although,  as  of  December  31,  2007,  we  believe  our 
intangible  assets  will  be  recoverable.    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 for the excess 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 9.

None.  

Item 9A.  Controls and Procedures 

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

36 

 
 
 
 
 
 
 
 
 
 
 
objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible 
controls and procedures. 

As of December 31, 2007, 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 the reasonable assurance level. 

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.  

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 
generally accepted accounting principles.    

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  generally  accepted  accounting  principles,  and  that 
receipts and expenditures of the Company are being made only in accordance with authorizations of the Company’s 
management  and  directors;  and  (3) provide  reasonable  assurance  regarding  prevention  or  timely  detection  of 
unauthorized  acquisition,  use  or  disposition  of  the  Company’s  assets  that  could  have  a  material  effect  on  the 
financial statements.  

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

In  connection  with  the  preparation  of  the  Company's  annual  financial  statements,  management  of  the 
Company  has  undertaken  an  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial 
reporting as of December 31, 2007 based on criteria established in Internal Control – Integrated Framework issued 
by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“the  COSO  Framework”).  
Management's  assessment  included  an  evaluation  of  the  design  of  the  Company's  internal  control  over  financial 
reporting and testing of the operational effectiveness of the Company's internal control over financial reporting. 

Based  on  this  assessment,  management  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, 2007. 

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. as of December 31, 2007 
and 2006, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the 
three  years  in  the  period  ended  December  31,  2007.  These  financial  statements  are  the  responsibility  of  the 
Company's  management.  Our  responsibility  is  to  express  an  opinion  on  these  financial  statements  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,  2007  and  2006,  and  the  consolidated  results  of  its 
operations and its cash flows for each of the three years in the period ended December 31, 2007, in conformity with 
U.S. generally accepted accounting principles.  

 As discussed in Note 2 to the consolidated financial statements, under the heading Stock-Based Compensation, 
the Company adopted Statement of Financial Accounting Standards No. 123(R), “Share-Based Payment”, effective 
January 1, 2006.   

As  also  discussed  in  Note  7  to  the  consolidated  financial  statements,  under  the  heading  Income  Taxes,  the 
Company adopted FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes- an interpretation of 
FASB Statement No. 109” effective January 1, 2007. 

We  also have audited,  in  accordance  with  the  standards of  the  Public  Company  Accounting Oversight  Board 
(United  States),  CoStar's  internal  control  over  financial  reporting  as  of  December  31,  2007,  based  on  criteria 
established in Internal Control Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission and our report dated February 22, 2008 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We have audited CoStar Group, Inc.’s (“CoStar”) internal control over financial reporting as of December 31, 
2007,  based  on  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (the COSO criteria).  CoStar’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. 

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

of December 31, 2007, 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  as  of  December  31,  2007  and  2006  and  the  related  consolidated 
statements  of  operations,  stockholders’  equity  and  cash  flows  for  each  of  the  three  years  in  the  period  ended 
December 31, 2007 of CoStar Group, Inc. and our report dated February 22, 2008 expressed an unqualified opinion 
thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

December 31, 2007 

1. ORGANIZATION 

CoStar  Group,  Inc.  (the  “Company”)  has  created  a  comprehensive,  proprietary  database  of  commercial  real 
estate  information  covering  the  United  States,  as  well  as  parts  of  the  United  Kingdom  and  France.  Based  on  its 
unique  database,  the  Company  provides  information  services  to  the  commercial  real  estate  and  related  business 
community  and  operates  within  two  segments,  U.S.  and  International.  The  Company’s  information  services  are 
typically  distributed  to  its  clients  under  subscription-based  license  agreements,  which  typically  have  a  minimum 
term of one year and renew automatically. 

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 significant 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 generally accepted accounting principles (“GAAP”) 
in the United States requires management to make estimates and assumptions that affect the amounts reported in the 
financial statements and accompanying notes. Actual results could differ from those estimates. 

Revenue Recognition 

The Company primarily derives revenues from providing access to its proprietary database of commercial real 
estate  information.  The  Company  generally  charges  a  fixed  monthly  amount  for  its  subscription-based  services. 
Subscription contract rates are based on the number of sites, number of users, organization size, the client’s business 
focus and the number of services to which a client subscribes. Subscription-based license agreements typically have 
a minimum term of one year and renew automatically. 

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 sales of subscription licenses and is recognized over the term of the license agreement.  

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 services. Additionally, 
cost  of  revenues  includes  the  cost  of  data  from  third-party  data  sources,  which  is  expensed  as  incurred,  and  the 
amortization of database technology. 

Significant Customers 

No  single  customer  accounted  for  more  than  5%  of  the  Company’s  revenues  for  each  of  the  years  ended 

December 31, 2005, 2006 and 2007.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ⎯ (Continued) 

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 as of the balance sheet date.  Revenue, 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 income. Net gains or losses resulting from foreign currency exchange transactions 
are included in the consolidated statements of operations. The Company had an increase in comprehensive income 
from the translation of its foreign subsidiary’s assets and liabilities into U.S. dollars of approximately $3.0 million 
and $873,000 for the years ended December 31, 2006 and 2007, respectively. There were no material gains or losses 
from foreign currency exchange transactions for the years ended December 31, 2006 and 2007. 

Comprehensive Income 

For the years ended December 31, 2005, 2006 and 2007, total comprehensive income was approximately $3.8 
million, $15.6 million and $17.1 million, respectively. As of December 31, 2007, accumulated other comprehensive 
income  included  foreign  currency  translation  adjustments  of  approximately  $5.5  million  and  unrealized  gains  on 
short-term investments of approximately $86,000. 

Advertising Costs 

The Company expenses advertising costs as incurred. Advertising expense were approximately $200,000, $4.0 

million and $2.3 million for the years ended December 31, 2005, 2006 and 2007, respectively. 

Income Taxes 

The Company provides for income taxes under the provisions of Statement of Financial Accounting Standards 
No.  109  “Accounting  for  Income  Taxes”  (“SFAS  No.  109”).  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 expected to be in effect during the year in 
which the differences reverse. Valuation allowances are provided against assets, including net operating losses, if it 
is anticipated that some or all of the asset may not be realized through future taxable earnings or implementation of 
tax planning strategies. 

Net Income Per Share 

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

Stock-Based Compensation 

On  January  1,  2006,  the  Company  adopted  Statement  of  Financial  Accounting  Standards  No.  123R  “Share 
Based Payment” (“SFAS 123R”), which addresses the accounting for share-based payment transactions in which the 
Company receives employee services in exchange for equity instruments. The statement eliminates the Company's 
ability to account for share-based compensation transactions as prescribed by Accounting Principles Board Opinion 
No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), and generally requires that equity instruments

Stock-Based Compensation ⎯  (Continued) 

issued  in  such  transactions  be  accounted  for  using  a  fair-value  based  method  and  the  fair  value  of  such  equity 
instruments be recognized as expense in the consolidated statements of operations. 

Under the fair-value recognition provisions of SFAS 123R, stock-based compensation cost is estimated at the 
grant date based on the fair value of the awards expected to vest and recognized as expense ratably over the requisite 
service  period  of  the  award.    The  Company  recognizes  compensation  costs  for  awards  with  graded  vesting  on  a 
straight-line basis. 

The Company adopted SFAS 123R using the modified prospective method, which requires the application of 
the  accounting  standard  as  of  January  1,  2006.  In  accordance  with  the  modified  prospective  method,  the 
consolidated financial statements for prior periods have not been restated to reflect, and do not include, the impact of 
SFAS  123R.  SFAS  123R  requires  forfeitures  to  be  estimated  at  the  time  of  grant  and  revised,  if  necessary,  in 
subsequent  periods  if  actual  forfeitures  differ  from  those  estimates.  In  the  pro  forma  information  required  under 
SFAS 123 for the periods prior to 2006, the Company accounted for forfeitures as they occurred. Upon adoption of 
SFAS  123R,  the  Company  recorded  a  charge  of  approximately  $35,000  representing  the  cumulative  effect  of  a 
change  in  accounting  principle.  This  amount  was  recorded  in  general  and  administrative  expenses  in  the 
consolidated statements of operations for the year ended December 31, 2006. 

The impact of the adoption of SFAS 123R on the Company's results of operations for the year ended December 

31, 2006, was as follows (in thousands, except per share data): 

Income from operations .............................................................................................................   $ 
Income before taxes ...................................................................................................................   $ 
Net income .................................................................................................................................   $

(2,860)

SFAS 123R requires cash flows resulting from excess tax benefits to be classified as part of cash flows from 
financing activities. Excess tax benefits represent tax benefits related to exercised options in excess of the associated 
deferred tax asset for such options. There were no excess tax benefits as a result of adopting SFAS 123R for the year 
ended December 31, 2006, and no amounts were classified as an operating cash outflow or a financing cash inflow 
in the accompanying condensed consolidated statement of cash flows.  Net cash proceeds from the exercise of stock 
options  were  approximately  $7.4  million;  $5.6  million  and  $8.1  million  for  the  years  ended  December  31,  2005, 
2006 and 2007, respectively.  There was approximately $260,000 of excess tax benefits realized from stock option 
exercises for the year ended December 31, 2007.

Prior  to  the  adoption  of  SFAS  123R,  the  Company  provided  the  disclosures  required  under  SFAS  123. 
Employee  stock-based  compensation  expense  recognized  under  SFAS  123R  was  not  reflected  in  the  Company's 
results of operations for the year ended December 31, 2005. Previously reported amounts have not been restated in 
the Company's financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ⎯ (Continued) 

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  United  States 
Government  Securities.  As  of  December  31,  2006  and  2007,  cash  of  $742,000  and  $754,000,  respectively,  was 
restricted to support letters of credit for security deposits. 

Short-Term Investments 

The  Company  accounts  for  short-term  investments  in  accordance  with  Statement  of  Financial  Accounting 
Standards  No.  115“Accounting  for  Certain  Investments  in  Debt  and  Equity  Securities”  (“SFAS  No.  115”),  The 
Company  determines  the  appropriate  classification  of  investments  at  the  time  of  purchase  and  reevaluates  such 
designation as of each balance sheet date.  The Company considers all of its investments to be available-for-sale.  
Investments  consist  of  commercial  paper,  government/federal  notes  and  bonds  and  corporate  obligations  with 
maturities greater than 90 days at the time  of purchase. Available-for-sale investments with contractual  maturities 
beyond one year are classified as current in the Company’s consolidated balance sheets because they represent the 
investment of cash that is available for current operations. Investments are carried at fair market value. 

Scheduled maturities of investments classified as available-for-sale as of December 31, 2007 are as follows (in 

thousands):

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 other comprehensive income in stockholders’ equity until 
realized.    Realized  gains  and  losses  from  the  sale  of  available-for-sale  securities  are  determined  on  a  specific-
identification  basis.  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. 

The  unrealized  losses  on  the  Company’s  investments  as  of  December  31,  2006  and  2007  were  generated 
primarily  from  increases  in  interest  rates.  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  has  the  ability  to  hold  these  investments  until  a  recovery  of  fair  value,  which  may  be 
maturity, it does not consider these investments to be other-than-temporarily impaired as of December 31, 2006 and

The  gross  unrealized  gains  as  of  December  31,  2006  and  2007  were  approximately  $50,000  and  $330,000, 

respectively.  

Auction rate securities are variable rate debt instruments whose interest rates are reset approximately every 28 
days.  The underlying securities have contractual maturities greater than twenty years.  The auction rate securities 
are  recorded  at  fair  value.    Typically,  the  carrying  value  of  auction  rate  securities  approximates  fair  value  due  to 
frequent resetting of the interest rates.  As of February 22, 2008, the Company held auction rate securities totaling 
$33.1 million of par value, of which $29.1 million failed to settle at auctions.  These investments are of high credit 
quality with AAA credit ratings and are primarily student loan securities supported by guarantees from the Federal 
Family Education Loan Program (FFELP) of the U.S. Department of Education.  The Company may not be able to 
liquidate  and  fully  recover  the  carrying  value  of  the  remaining  auction  rate  securities  in  the  near  term.    These 
developments  may  result  in  the  classification  of  some  or  all  of  these  securities  as  long-term  investments  in  the 
Company’s consolidated financial statements for the first quarter of 2008.  In addition, while all of the auction rate 
securities  are  currently  rated  AAA,  if  the  issuers  are  unable  to  successfully  close  future  auctions  and  their  credit 
ratings deteriorate, the Company may be required to record an impairment charge on these investments.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ⎯ (Continued) 

Concentration of Credit Risk and Financial Instruments 

The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not 
require  that  its  customers’  obligations  to  the  Company  be  secured.  The  Company  maintains  reserves  for  credit 
losses, and such losses have been within management’s expectations. The large size and widespread nature of the 
Company’s customer base and lack of dependence on individual customers mitigate the risk of nonpayment of the 
Company’s  accounts  receivable.  The  carrying  amount  of  the  accounts  receivable  approximates  the  net  realizable 
value. The carrying value of the Company’s financial instruments including cash and cash equivalents, short-term 
investments, accounts receivable, accounts payable, and accrued expenses approximates fair value. 

Property and Equipment 

Property  and  equipment  are  stated  at  cost.  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 seven years 
  Five years 
  Two to five years 

Internal use software costs are capitalized in accordance with Statement of Position No. 98-1, “Accounting for 
the Costs of Computer Software Developed or Obtained for Internal Use” (“SOP 98-1”). Qualifying costs incurred 
during  the  application  development  stage,  which  consist  primarily  of  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, Intangibles and Other Assets 

Goodwill  represents  the  excess  of  costs  over  the  fair  value  of  assets  of  businesses  acquired.  Goodwill  and 
intangible assets subject to amortization that arose from acquisitions prior to July 1, 2001, have been amortized on a 
straight-line basis over their estimated useful lives in accordance with Accounting Principles Board Opinion No. 17, 
“Intangible  Assets”  (“APB  17”).  The  Company  adopted  the  provisions  of  Statement  of  Financial  Accounting 
Standards  No. 142, “Goodwill  and  Other  Intangible  Assets”  (“SFAS 142”),  as of  January  1, 2002. Goodwill  and 
intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are 
not amortized, but instead tested for impairment at least  annually in accordance with the provisions of SFAS No. 
142. SFAS No. 142 also requires that intangible assets with estimable useful lives that arose from acquisitions on or 
after  July  1,  2001,  be  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, and 
reviewed for impairment in accordance with Statement of Financial Accounting Standards No. 144 (“SFAS 144”), 
“Accounting for Impairment or Disposal of Long-Lived Assets”.  

Acquired  database  technology,  customer  base  and  trade  names  and  other  are  related  to  the  Company’s 
acquisitions  (See  Notes  3  and  6).  Acquired  database  technology  and  trade  names  and  other  are  amortized  on  a 
straight-line  basis  over  periods  ranging  from  two  to  ten  years.  The  acquired  intangible  asset  characterized  as 
customer  base  consists  of  one  distinct  intangible  asset  composed  of  acquired  customer  contracts  and  the  related 
customer relationships. Acquired customer bases that arose from acquisitions prior to July 1, 2001 are amortized on 
a straight-line basis principally over a period of ten years. Acquired customer bases that arose from acquisitions on 
or  after  July  1,  2001  are  amortized  on  a  125%  declining  balance  method  over  ten  years.  The  cost  of  capitalized 
building photography is amortized on a straight-line basis over five years.

Long-Lived Assets 

In  accordance  with  SFAS  144,  long-lived  assets,  such  as  property,  plant,  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 estimate 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 by the amount for 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 
disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections 
of the balance sheet. 

Goodwill and intangible assets not subject to amortization are tested annually for impairment, and are tested for 
impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment 
loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. 

Recent Accounting Pronouncements 

In  June  2006,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  FASB  Interpretation  No.  48 
“Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109” (“FIN 48”), which 
became effective for the Company as of January 1, 2007. FIN 48 addresses the determination of how tax benefits 
claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FIN 48, the 
Company must recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the tax 
position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. 
The  tax  benefits  recognized  in  the  financial  statements  from  such  a  position  are  measured  based  on  the  largest 
benefit  that has  a greater  than fifty  percent  likelihood of being realized upon ultimate  resolution.  The  Company’s 
reassessment  of  its  tax  positions  in  accordance  with  FIN  48  did  not  have  a  material  impact  on  its  results  of 
operations and financial position. 

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”), which defines 
fair  value,  establishes  a  framework  for  measuring  fair  value  in  accordance  with  GAAP  and  expands  disclosures 
about fair value measurements. SFAS 157 does not require any new fair value measurements under GAAP and is 
effective  for  fiscal  years  beginning  after  November 15,  2007. The  effects  of  adoption  will  be  determined  by  the 
types of instruments carried at fair value in the Company’s financial statements at the time of adoption as well as the 
method utilized to determine their fair values prior to adoption. The adoption of SFAS 157 is not expected to have a 
material effect on the results of operations or financial position of the Company.  

In  February  2007,  the  FASB  issued  SFAS No. 159,  “Fair  Value  Option  for  Financial  Assets  and  Financial 
Liabilities — Including an amendment of FASB Statement No. 115” (“SFAS 159”), which permits entities to choose 
to measure many financial instruments and certain other items at fair value. SFAS 159 is effective for fiscal years 
beginning on or after December 31, 2007. The Company has assessed the provisions of SFAS 159 and determined 
that it is not expected to have a material effect on the results of operations or financial position of the Company. 

In  December 2007,  the  FASB  issued  SFAS 141  (Revised  2007),  “Business  Combinations”  (“SFAS  141R”), 
which will change the accounting for any business combination the Company  enters into with an acquisition date 
after December 31, 2008. Under SFAS 141R, an acquiring entity will be required to recognize all the assets acquired 
and liabilities assumed in a transaction at the acquisition date fair value with limited exceptions. SFAS 141R will 
change  the  accounting  treatment  and  disclosure  for  certain  specific  items  in  a  business  combination.  SFAS 141R 
will have an impact on accounting for business combinations once adopted but its effect will be dependent upon the 
specifics of any business combination with an acquisition date subsequent to the date of adoption.

In  December 2007,  the  FASB  issued  SFAS 160  “Noncontrolling  Interests  in  Consolidated  Financial 
Statements—An  Amendment  of  ARB No.  51”  (“SFAS  160”),  which  establishes  new  accounting  and  reporting 
standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 is 
effective for fiscal years beginning on or after December 15, 2008. The adoption of SFAS 160 is not expected to 
have a material impact on the results of operations or financial position of the Company.  

3. ACQUISITIONS 

On December 21, 2006, CoStar Limited, a wholly owned U.K. subsidiary of CoStar, acquired Grecam S.A.S. 
(“Grecam”),  a  provider  of  commercial  property  information  and  market-level  surveys,  studies  and  consulting 
services  located  in  Paris,  France.  The  Company  acquired  all  of  the  outstanding  capital  stock  of  Grecam  for 
approximately $2.0 million in cash.  

On  February 16,  2007,  CoStar  Limited  acquired  all  of  the  outstanding  capital  stock  of  Property  Investment 
Exchange  Limited  (“Propex”)  for  approximately  $22.0 million,  consisting  of  cash,  deferred  consideration  of 
approximately  $2.9  million,  and  21,526 shares  of  CoStar  common  stock.  Propex  provides  web-based  commercial 
property information and operates an electronic platform that facilitates the exchange of investment property in the 
U.K. Propex’s suite of electronic platforms and listing websites give users access to the U.K. commercial property 
investment and leasing markets. 

These acquisitions were accounted for using purchase accounting. The purchase price for each acquisition was 
primarily  allocated  to  acquired  database  technology,  customer  base,  trade  names,  and  goodwill.  The  acquired 
database technology is being amortized on a straight-line basis over four years. The acquired customer base for the 
acquisitions,  which  consists  of  one  distinct  intangible  asset  for  each  acquisition  and  is  composed  of  acquired 
customer contracts and the related customer relationships, is being amortized on a 125% declining balance method 
over ten years. The Grecam and Propex acquired trade names are being amortized on a straight-line basis over three 
years. Goodwill is not amortized, but is subject to annual impairment tests. The results of operations of Grecam and 
Propex have been consolidated with those of the Company since the respective dates of the acquisitions and are not 
considered  material  to  the  consolidated  financial  statements  of  the  Company.  Accordingly,  pro  forma  financial 
information has not been presented for either acquisition.

The  Company  recorded goodwill  of  approximately  $15.0  million  for  the  Propex  acquisition  in  February 2007.  

The remaining increase in goodwill in 2007 is related to foreign currency fluctuations. 

During  the fourth quarters of  2006  and 2007,  the  Company  completed  the  annual  impairment  test  of  goodwill 

and concluded that goodwill was not impaired.

For  the  years  ended  December  31,  2006  and  2007,  a  valuation  allowance  has  been  established  primarily  for 
certain  state  net  operating  loss  carryforwards  due  to  the  uncertainty  of  realization.  The  Company’s  change  in 
valuation  allowance  was  approximately  $350,000  and  $274,000  during  the  years  ended  December  31,  2006  and 
2007,  respectively.    For  the  year  ended  December  31,  2007,  the  Company  had  income  of  approximately  $30.3 
million subject to applicable U.S. federal and state income tax laws and a loss of approximately $4.4 million subject 
to applicable U.K. tax laws.     

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

The  Company  paid  approximately  $95,000,  $858,000  and  $1.1  million  in  income  taxes  for  the  years  ended 

December 31, 2005, 2006 and 2007, respectively. 

At  December 31,  2007,  the Company  has net  operating  loss  carryforwards for federal  income  tax  purposes of 
approximately $14.9 million, which expire, if unused, from the year 2013 through the year 2023. The Company has 
net operating loss carryforwards for U.K. income tax purposes of approximately $8.1 million, which do not expire. 
The Company also has alternative minimum tax credit carryforwards of approximately $1.4 million. 

The Company adopted FIN 48 on January 1, 2007. As a result of the implementation of FIN 48, the Company 
recognized  no  material  adjustment  in  the  liability  for  unrecognized  income  tax  benefits.  At  the  adoption  date  of 
January 1, 2007, the Company had $226,000 of unrecognized tax benefits, all of which would favorably affect the 
effective  tax  rate  if  recognized  in  future  periods.  The  Company’s  continuing  practice  is  to  recognize  interest  and 
penalties related to income tax matters in income tax expense.  

The following table summarizes the activity related to the Company’s unrecognized tax benefits (in thousands):

The unrecognized tax benefit of $260,000 as of December 31, 2007, would favorably affect the annual effective 
tax  rate,  if  recognized  in  future  periods.  The  unrecognized  tax  benefit  includes  approximately  $24,000  of  interest 
and  $10,000 of  penalties  accrued during 2007,  and  approximately  $49,000  of  interest and  $57,000 of  penalties  in 
total  as  of  December  31,  2007.  The  Company  does  not  anticipate  the  amount  of  the  unrecognized  tax  benefits  to 
change significantly over the next twelve months.

10.  SEGMENT REPORTING 

Due  to  the  increased  size,  complexity,  and  funding  requirements  associated  with  the  Company’s  international 
expansion in 2007, the Company began to manage the business geographically in two operating segments, with the 
primary areas of measurement and decision-making being the U.S. and International, which includes the U.K. and 
France.  The  U.S.  and  International  segment  revenue  is  comprised  of  subscription  based  information  services 
consisting  primarily  of  CoStar  Property  Professional,  CoStar  Tenant,  CoStar  COMPS  Professional  and  FOCUS 
services,  and  currently  generates  approximately  95%  of  our  total  revenues.  Management  relies  on  an  internal 
management  reporting  process  that  provides  revenue  and  segment  EBITDA,  which  is  the  Company’s  net  income 
before  interest,  income  taxes,  depreciation  and  amortization.  Management  believes  that  segment  EBITDA  is  an 
appropriate measure for evaluating the operational performance of our 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.

13. EMPLOYEE BENEFIT PLANS 

Stock Incentive Plans  

In June 1998, the Company’s Board of Directors adopted the 1998 Stock Incentive Plan (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 are available 
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 provides 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 might be incentive or 
non-qualified.  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  is 
determined  by  the  Board  of  Directors  and  is  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.  

The  2007  Plan  provides  for  the  grant  of  stock  options,  restricted  stock,  restricted  stock  units,  and  stock 
appreciation rights to officers, employees and directors of the Company and its subsidiaries. Stock options granted 
under the 2007 Plan may be non-qualified or may qualify as incentive stock options. 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 and is generally three to four years, subject to minimum vesting periods of at 
least one year. The Company has reserved the following shares of common stock for issuance under the 2007 Plan: 
(a) 1,000,000 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 are 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  1.1  million  shares  were  available  for  future  grant  under  the  2007  Plan  as  of 
December 31, 2007.

The aggregate intrinsic value is calculated as the difference between (i) the closing price of the common stock at 
December 31, 2005, 2006 and 2007 and (ii) the exercise prices of the underlying awards, multiplied by  the shares 
underlying options as of December 31, 2005, 2006 and 2007, that had an exercise price less than the closing price on 
that date. Options to purchase 292,474, 269,755, and 288,757 shares were exercised for the years ended December 
31, 2005, 2006, and 2007, respectively.  The aggregate intrinsic value of options exercised, determined as of the date 
of option exercise, was $5.9 million, $7.4 million and $7.5 million, respectively.  

At  December  31,  2007,  there  was  $11.1  million  of  unrecognized  compensation  cost  related  to  stock-based 

payments, net of forfeitures, which is expected to be recognized over a weighted-average-period of 2.1 years. 

The weighted-average grant date fair value of each option granted during the years ended December 2005, 2006 

and 2007 was $26.65, $33.45 and $32.70, 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 noted in the following table:

The  assumptions  above  and  the  estimation  of  expected  forfeitures  are  based  on  multiple  facts,  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.

COSTAR GROUP, INC. 

13. EMPLOYEE BENEFIT PLANS ⎯ (Continued) 

Employee 401(k) Plan  

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  Internal  Revenue Service. In  2005, 2006 and 2007,  the Company  matched  100% of 
employee contributions up to a maximum of 6% of total compensation. Amounts contributed to the 401(k) by the 
Company  to  match  employee  contributions  for  the  years  ended  December  31,  2005,  2006  and  2007  were 
approximately $1.6 million, $2.0 million and $2.3 million, respectively. The Company paid administrative expenses 
in connection with the 401(k) plan of approximately $18,000, $25,000 and $22,000 for the years ended December 
31, 2005, 2006 and 2007, respectively. 

Employee Pension Plan 

The Company maintains a company personal pension plan for all eligible employees in the Company’s London, 
England  office.  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  the  Inland  Revenue.  The  Company  contributes  a 
match subject to the percentage of the employees’ contribution. Amounts contributed to the plan by the Company to 
match  employee  contributions  for  the  years  ended  December  31,  2005,  2006  and  2007  were  approximately 
$175,000, $193,000 and $281,000, respectively. 

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 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 the offering period. The offering 
period  begins  the  Saturday  before  each  of  the  Company’s  regular  pay  dates  and  ends  on  each  of  the  Company’s 
regular pay dates.  There were 95,489 and 86,308 shares available for purchase under the plan as of December 31, 
2006  and  2007,  respectively  and  approximately  4,000  and  9,000  shares  of  the  Company’s  common  stock  were 
purchased during 2006 and 2007, respectively.
