TO OUR
SHAREHOLDERS

In  2008,  CoStar  Group  continued  its  track  record  of 
success with another year of strong financial and operational 
results that enabled us to achieve the earnings goals we set 
two  years  ago  and  strengthen  our  already  strong  financial 
position.  Our  financial  results  reflect  CoStar  Group’s  three 
core attributes as a company – our industry-leading research, 
the value our services provide subscribers, and the underlying 
strength of our subscription-based business model.

In  2006,  we  embarked  on  the  most  ambitious  expansion  
in CoStar’s history to-date, making a substantial investment 
to create additional value for our subscribers and investors by 
significantly expanding our commercial real estate coverage 
in both the U.S. and the U.K.  In 2007, we largely completed the 
work  of  adding  hundreds  of  thousands  of  new  properties  to 
our database, setting the stage in 2008 to focus on leveraging 
those  investments  and  generate  the  substantial  earnings 
growth we expected. 

I’m  pleased  to  report  that  we  delivered  on  that  goal  and 
exceeded  expectations  by  successfully  growing  earnings 
to  their  highest  levels  in  our  company’s  history.  Net  income 
increased  145%  to  $24.6  million  in  2008,  compared  to  $10.1 
million  for  2007.  EBITDA  (earnings  before  interest,  taxes, 
depreciation  and  amortization)  for  the  full  year  in  2008  was 
$56.6 million, a 115% increase compared to EBITDA of $26.4 
million  in  20071.  The  fact  that  we  successfully  executed  the 
plan we provided to our investors in the midst of a challenging 
economic  environment  I  believe  clearly  demonstrates  our 
company’s proven ability to create growth opportunities and 
increase shareholder value.

Also,  by  continuing  to  increase  our  business  margins  in  the 
U.S. and ensuring that our expanded International operations 
became  profitable  as  expected,  we  succeeded  in  achieving 
another  important  goal  in  2008:  raising  our  company-wide 
EBITDA earnings margin to 30%. Our focus on earnings growth 
has  had  the  added  benefit  of  significantly  strengthening  our 
balance sheet. During 2008, we added more than $37 million 
to our cash balance for a total of $225 million in cash, cash 
equivalents and investments on hand at the end of the year. 

By  focusing  on  earnings  growth,  effectively  managing  our 
costs  and  continuing  to  provide  real  value  to  our  clients, 
CoStar  Group  ended  the  year  in  a  very  favorable  position  -- 
solidly profitable, with no debt and very large cash reserves.

RESEARCH

Need for Research-Verified, 
Comprehensive Information 
Never Greater

I  believe  our  2008  results  affirm  CoStar  Group’s  unique 
qualifications to research commercial real estate markets 
and  address  our  subscribers’  most  critical  business 
information  needs.  And  given  the  current  economic 
circumstances,  I  further  believe  the  need  for  CoStar’s 
comprehensive,  research-verified  information  has  never 
been greater.  

Each  year,  hundreds  of  thousands  of  transactions  are 
completed  across  the  $5  trillion  commercial  real  estate 
industry.  These  transactions  often  have  millions  of 
dollars at stake and require the confirmation of hundreds 
of  detailed  facts  on  the  properties  involved,  as  well  as 
on  other  properties  they  directly  compete  against.  More 
information  is  needed  to  analyze  current  market  trends 
and conditions that may affect property values. Every day,  
brokers, lenders, investors, appraisers, property owners 
--  all  of  those  directly  involved  in  making  decisions  on 
where to buy, sell and lease commercial property -- turn 
to CoStar for the property-specific information they need.

Better  information  invariably  results  in  better  decisions.  
At a time when every real estate transaction is undergoing 
rigorous scrutiny, demand for trusted, verified information 
is  at  a  premium,  and  access  to  CoStar’s  information 
becomes  even  more  highly  prized.  Only  CoStar  offers 
the  detailed  building-by-building  information  in  what 
we  believe  to  be  the  most  comprehensive  and  accurate 
database  of  commercial  property  in  the  U.S.  and  U.K, 
providing unmatched insight and clarity.

Having successfully integrated the significant increase in 
listings and researched properties during our most recent 
expansion,  CoStar’s  research  operations  continued  to 
perform exceedingly well in 2008.  At the end of the year 
our massive database included detailed information on 3.2 
million properties totaling just under 65 billion square feet, 
with 8.7 billion square feet of available space and property 
listings totaling more than $1 trillion in total value. 

Our research organization continually adds to these totals, 
expanding the scope of our coverage and maintaining the 
accuracy  of  the  information  on  an  on-going  basis,  far 
eclipsing what we believe any single real estate services 
firm could cost-effectively accomplish on its own.

By  outsourcing  the  labor-intensive  and  time-consuming 
task of researching the entire commercial property market 
to CoStar, these commercial real estate service providers 
gain  access  to  higher  quality,  more  comprehensive 
information  at  a  lower  cost,  enabling  these  real  estate 
service providers to focus their resources on negotiating 
transactions and delivering services to their clients.

Because CoStar’s information services help our customers 
improve productivity, lower costs and drive new revenues, 
we  believe  there  will  be  continued  strong  demand  for 
our  services,  and  we  expect  to  continue  to  provide  the 
comprehensive,  high  quality  information  that  has  set 
CoStar apart and won us the business of essentially every 
major  firm  in  commercial  real  estate  as  their  trusted 
source of reliable and valuable data. 

CoStar’s information helps our
customers improve productivity,  
lower costs and drive new revenue.

We believe the extraordinary demonstration of acceptance of 
this new service in such a short period of time is a testament 
to CoStar Showcase’s overall utility and effectiveness. It also 
serves to further expand our company’s focus more directly 
than  ever  into  the  marketing  side  of  the  commercial  real 
estate business. 

For  more  than  two  decades,  our  clients  have  thought  of 
CoStar  primarily  as  their  research  partner.  With  CoStar 
Showcase, we have taken a major step to positioning CoStar 
as  their  marketing  partner  as  well.  And  the  timing  could 
not have been better. In helping brokers generate leads at 
a lower cost than other marketing alternatives, we believe 
CoStar Showcase offers real value to listing brokers seeking 
added  exposure  for  their  properties  online,  and  is  exactly 
the type of cost-effective lead generation solution they are 
looking for.

TECHNOLOGY + INNOVATION

Driving Growth Through 
Technology and Innovation

In addition to our dominant position as the largest research 
organization  in  commercial  real  estate,  CoStar  also  is  a 
technology  leader  that  stands  out  by  delivering  the  ability 
to  access  and  analyze  information  for  greater  insight,  and 
to  gain  a  sharper  competitive  edge  by  marketing  property 
listings  more  efficiently  and  more  effectively  across  our 
secure, high-speed network. 

information  technology  group 

is  continually 
CoStar’s 
developing  and  releasing  enhancements  to  our  powerful 
information  services.  And  last  year  we  made  a  number  of 
behind-the-scenes enhancements to make our network even 
faster  and  more  reliable,  befitting  an  advanced  business 
information platform. 

One major area of focus for our technology group planned 
for 2009 will be an expansion of analytic capabilities using 
CoStar’s information. The overwhelming response from our 
clients who participated in a series of webinars addressing 
changing market conditions clearly showed the demand for 
CoStar to expand our role as a data provider and to provide 
clients with additional market analysis and insight. In addition 
to  benefiting  from  CoStar’s  superior  research  and  market 
coverage,  we  believe  our  core  subscribers  would  greatly 
value  the  ability  to  conduct  more  in-depth  analysis  using 
the  extensive  information  we  provide.  We  intend  to  pursue 
that option in the near future  and believe it will be very well 
received.

The  year  was  also  notable  in  terms  of  new  product 
development with the May 2008 launch of CoStar Showcase®. 
This  new  service  provides  commercial  real  estate 
professionals with a highly effective channel for generating 
leads from the tens of thousands of business professionals 
who search the Internet every day for available commercial 
real estate.

In  less  than  a  year  in  service,  annualized  sales  for  CoStar 
Showcase reached nearly $3 million at the end of 2008, making 
it one of the most successful new services we ever launched 
and providing another example of how CoStar continues to 
use technology and innovation to expand our service platform 
and generate additional growth opportunities. 

A technology leader that stands out
by delivering the ability to access and 
analyze information for greater insight 
and a sharper competitive edge.

A MAJOR GROWTH OPPORTUNITY

Information Remains a  
Billion Dollar Business  

In  closing,  I  wish  to  reiterate  what  I  have  often  stated  in 
previous  discussions  with  investors:  I  firmly  believe  that 
providing  information  and  marketing  services  to  the 
commercial  real  estate  sector  remains  a  billion  dollar 
business opportunity. It was before this current recession, 
and it will be again when the inevitable upturn follows and 
business  conditions  improve.  We  intend  to  keep  CoStar 
Group at the forefront of this opportunity by continuing to 
provide  an  overwhelming  quality  advantage  and  serving 
as an indispensable resource for our customers.

Over  the  past  two  decades,  we  have  set  and  achieved 
numerous earnings goals. And we remain focused on our 
current goal of reaching $100 million in annualized EBITDA 
companywide. If, as expected, we see positive GDP growth 
return before 2010, I believe CoStar is well positioned to 
capture  that  growth,  continuing  the  track  record  we’ve 
compiled in setting and achieving earnings goals.

Going  forward,  CoStar  Group’s  focus  will  remain  on 
building  and  growing  integrated  research,  information 
and marketing services for commercial real estate clients 
throughout  the  U.S.  and  U.K.  We  see  opportunity  in  the 
current environment to capitalize on our existing research 
assets to introduce new products and services and expand 
our business in key areas, while positioning the company 
for accelerated growth in the future.

We believe, we are still in the early stages of penetrating 
the  total  potential  market  for  commercial  real  estate 
information  services  in  the  many  U.S.  and  U.K.  markets 
we  added  during  our  most  recent  expansion.  And,  as 
our  financial  performance  over  the  past  two  decades 
has  consistently  demonstrated,  once  established  as  the 
information provider in a market, we expect to continue 
to add new clients and create the opportunity to generate 
sustained revenue associated with that market for decades 
into the future.  

We believe that the opportunity to reach new customers 
with  our  core  services  in  these  recently  added  markets, 
together  with  continued  success  in  selling  additional 
services  to  existing  customers,  presents  a  compelling 
opportunity for significant, long-term revenue growth.

The  tremendous  growth  we’ve  seen  over  the  past  two 
decades  has  been  driven  by  consistent,  predictable 
subscription-based  revenues  and  high  renewal  rates 
among our core subscribers. Our proven business model 
is  based  on  the  extensive  economies  of  scale  that  exist 
in  researching  commercial  real  estate  and  providing 
information and marketing services to large numbers of 
subscribers across multiple markets. 

Having  established  our  research 
infrastructure  and 
proprietary technology to aggregate and confirm property 
information on such a large scale, we are able to allocate 
our  relatively  fixed  research  costs  across  our  extensive 
subscriber base. In doing so, CoStar solves a key business 
need, providing subscribers with access to comprehensive, 
research-verified  commercial  property  and 
tenant 
information at a fraction of the cost for an individual firm 
to produce comparable information, and enabling them to 
focus their resources on activities that generate revenue.

We believe the fact that our revenue grew by 10 percent and 
that we posted record earnings in 2008 reflects the strong 
fundamentals of our business and the value our services  
provide  to  our  customers.  Our  solid  financial  position  
is  based  on  long-term  investments  that  we  expect  will 
continue to generate additional revenue opportunities.  

I  am  confident  that  we  will  manage  our  costs  and  take 
advantage  of  our  strong  financial  position  to  invest  in 
areas that offer the greatest possibility for delivering long-
term value to our customers and shareholders, bringing 
additional  opportunity  to  our  employees,  and  additional 
growth opportunities for CoStar Group.  Thank you.

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 number one provider of information/marketing 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/marketing 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 (now, CoStar U.K. 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  12  to  our  consolidated  financial  statements.  CoStar’s  revenues,  net  income, 
assets  and  liabilities,  broken  out  by  segment  are  set  forth  in  Note  12  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,  internet  marketing  services,  property  information  for  clients’  websites,  information  about 
industry  professionals  and  their  business  relationships,  analytic  information,  data  integration,  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 we have supplied. 

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/marketing  services;  and  a  large  base  of  clients.  Our  database  has  been 
developed and enhanced for more than 21 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/marketing 
services.  In 2004, CoStar began research for a 21-market U.S. expansion effort.  By the end of 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.  We launched the new retail component of our flagship product, CoStar 
Property  Professional,  in  May  2006. 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. In 2008, we 
released  CoStar  Showcase,  an  internet  marketing  service  that  provides  commercial  real  estate  professionals  the 
opportunity to make their listings accessible to all visitors to our public website, www.CoStar.com.  

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.  Further information about CoStar’s acquisitions is included in 
Note 3 to our consolidated financial statements.      

Our  subscription-based  information/marketing  services,  consisting  primarily  of  CoStar  Property  Professional, 
CoStar Tenant, CoStar COMPS Professional and FOCUS services, currently generate more then 90% of our total 
revenues. Our contracts for our subscription-based information/marketing services typically have a minimum term 
of  one  year  and  renew  automatically.  Upon  renewal,  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, properties for sale, 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 
•  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. 

4 

 
 
 
 
 
 
 
 
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,  approximately  900  researchers  and  outside 
contractors, technological expertise and broad customer base, CoStar believes that it has created such a platform. 

The  U.S.  and global  economies  have  changed  adversely  over  the past  year  or  more,  and  the  commercial  real 
estate industry has been negatively impacted.  The commercial real estate market has seen a reduction in property 
sales  and  leasing  activity,  lower  absorption  rates,  climbing  vacancy  rates  and  decreases  in  rental  rates  and  sales 
prices.  The full extent of the impact of our current financial crisis is not yet clear.  As our customers continue to 
look for ways to reduce spending, we may continue to see reduced demand for our information/marketing services.  
However,  we  believe  that  even  in  a  weakened  economy  there  is  a  continuing  need  for  accurate,  standardized 
commercial real estate information/marketing services.  We believe that access to continuously researched verified 
commercial real estate information becomes even more valuable in a down market, as industry players assess where 
market conditions are heading, how their businesses should adapt, determine what properties are worth, and try to 
market their properties, among other things.  Moreover, outsourcing the labor-intensive task of conducting basic real 
estate research may result in cost savings for our clients. 

CoStar’s Comprehensive Database  

CoStar has spent more than 21 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 30, 2009, 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 1.1 million sale and lease listings; 
•  Over 3.2 million total properties; 
•  Over 8.9 billion square feet of sale and lease listings; 
•  Over 5.7 million tenants; 
•  More than 1.3 million sales transactions valued in the aggregate at over $3.1 trillion; and 
•  Approximately 7.6 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 
2008, our full time researchers and contractors drove millions of miles, conducted hundreds of thousands of on-site 
building inspections, and conducted millions of interviews of brokers, owners and tenants. 

Research  Department.  As  of  January  30,  2009,  we  have  approximately  900  commercial  real  estate  research 
professionals and 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, 

5 

 
 
 
 
 
 
 
 
 
 
 
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.   

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  utilizes  147  high-tech  field  research  vehicles  in  41  states  and  the  U.K.    Of  these  vehicles,  100  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/marketing 
services  and  include  what  we  believe  are  standard  terms,  such  as  a  contract  term  ranging  from  one  to  five  years, 
automatic renewal of the contract and fixed periodic license fees or a combination of fixed periodic license fees plus 
additional fees based upon our usage. 

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

• 
• 

• 
• 
• 

calling our information sources on recently updated properties to re-verify information; 
reviewing calls our researchers made to their industry contacts to ensure data reported to the researcher is  
entered correctly into the database;  
performing periodic research audits and field checks to determine if we correctly canvassed buildings; 
providing training and retraining to our research professionals to ensure accurate data compilation; and 
compiling measurable performance metrics for research teams and managers for feedback on data quality. 

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

commercial real estate professionals using our data every day. 

Proprietary Technology 

As  of  January  30,  2009,  CoStar  had  a  staff  of  90  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 Showcase, CoStar

Commercial  MLS  and  CoStar  Connect,  as  well  as  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 Professional including tenant proximity and demographic search capability, 
mapping layers, detailed retail tenant information and demographics.  In 2008, CoStar released CoStar Showcase, an 
internet marketing service that provides commercial real estate professionals the opportunity to make their listings 
accessible  to  all  visitors  to  our  public  website,  www.CoStar.com.  CoStar  has  also  begun  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/marketing services 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. In 
addition,  our  information  technology  team  has  also  developed  fraud-detection  technology  to  detect  and  prevent 
unauthorized access to our services.  

Our  information  technology  professionals  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/marketing 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/marketing  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/marketing services are described in detail in the following paragraphs as of January 30,

find  commercial  properties.   When  customers  sign  up  for  CoStar  Showcase,  their  listings  become  accessible  to 
visitors  to  Costar.com,  who  can  search  those  listings  for  free.   To  drive  traffic  to  CoStar  Showcase  subscriber 
listings,  CoStar  invests  in  GoogleTM  and  Yahoo®  keyword  based  pay-per-click  advertising  to  capture  the  high 
volume traffic of users actively searching for commercial properties on those search engines.  As part of their CoStar 
Showcase subscription, subscribers also receive customized websites for each of their brokers that displays their bio, 
photo, contact information and updated listings that they can use to promote their services.

information  to  market  their  U.S.  property  listings  on  their  corporate  websites.  Customers  enhance  the  quality  and 
depth  of  their  listing  information  through  access  to  CoStar’s  database  of  content  and  digital  images.  The  service 
automatically  updates  via  the  CoStar  Property  database  and  manages  customers’  online  property  information,

Commercial  MLS  represents  an  efficient  means  for  sellers  to  market  their  properties  to  a  large  audience  and  for 
buyers to easily identify target properties.   

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, 2006, 2007 and 2008, no single client accounted for more than 5% of our 

revenues.  

Sales and Marketing 

As of January 30, 2009, we had 220 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  22  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  actively  manage  client  accounts  in  order  to  retain  clients  by  providing 
frequent  service  demonstrations  as  well  as  company-client  contact  and  communication.    We  place  a  premium  on 
training new and existing client personnel on the use of our services so as to promote maximum client utilization and 
satisfaction with our services. Our strategy also involves entering into multi-year, multi-market license agreements 
with our larger clients.   

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 generally 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 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. 

In May 2008, we released CoStar Showcase®, an internet marketing service that provides commercial real estate 
professionals the opportunity to make their listings available to all visitors to our public website, www.CoStar.com, 
and allows each visitor to search those property listings for free. CoStar Showcase draws additional traffic to our 
website  through  searches  on  GoogleTM  and  Yahoo®.  Commercial  real  estate  listings  are  derived  from  our 
database and are researched and verified by CoStar researchers.  CoStar Showcase subscribers need only designate 
their listings for inclusion in the free property search tool. In addition, CoStar Showcase customers who have not 
subscribed for our other services, serve as leads for additional cross-selling opportunities.

Competition 

The  market  for  information/marketing  services  generally  is  competitive  and  rapidly  changing.  In  the 
commercial real estate industry, the principal competitive factors for commercial real estate information/marketing 
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;  
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, officespace.com, MrOfficeSpace.com, and TenantWise, Inc; 

publishers  and  distributors  of  information/marketing  services,  including  regional  providers  and  national 
print  publications,  such  as  Black’s  Guide,  Property  and  Portfolio  Research,  Torto  Wheaton  Research, 
Marshall & Swift, Yale Robbins, Inc., Reis, Inc., Real Capital Analytics, Inc. and The Smith Guide, Inc.; 

locally controlled real estate boards, exchanges or associations sponsoring property listing services and the 
companies with whom they partner, such as Xceligent, Catalyst, the National Association of Realtors, 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/marketing  services  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 

12 

 
 
 
 
 
 
 
  
 
 
 
 
 
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/marketing 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  established  an  internal  antipiracy  team  that  uses  fraud-detection  technology  to  continually 
monitor our services to detect and prevent unauthorized access, and we actively prosecute individuals and firms that 
engage in this unlawful activity. 

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”, “CoStar Showcase” 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 30, 2009, we employed 1,178 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.

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  on-going  downturn  in  the  commercial  real  estate  market’s  for  sale  activity  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/marketing  services.  Also,  companies  in  this  industry  are  consolidating,  often  in  order  to  reduce 
expenses.  Consolidation,  or  other  cost-cutting  measures  by  our  customers,  may  lead  to  more  cancellations  of  our 
information/marketing 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 
to decline and reduce our profitability. 

Negative general economic conditions could increase our expenses and reduce our revenues. Our business and 
the commercial real estate industry are particularly affected by negative trends in the general economy. The success 
of  our  business  depends  on  a  number  of  factors  relating  to  general  global,  national,  regional  and  local  economic 
conditions,  including  perceived  and  actual  economic  conditions,  recessions,  inflation,  deflation,  exchange  rates, 
interest  rates,  taxation  policies,  availability  of  credit,  employment  levels,  and  wage  and  salary  levels.  Negative 
general  economic  conditions  could  adversely  affect  our  business  by  reducing  our  revenues  and  profitability.  
Further,  continuing  bank  failures  and  freezing  of  the  credit  markets  generally,  other  adverse  national  and  global 
economic  events,  as  well  as  any  significant  terrorist  attack,  are  likely  to  have  a  further  dampening  effect  on  the 
economy  in  general,  which  could  negatively  affect  our  financial  performance  and  our  stock  price.  Market 

14 

 
 
 
 
 
disruptions  may  also  contribute  to  extreme  price  and  volume  fluctuations  in  the  stock  market  that  may  affect  our 
stock price for reasons unrelated to our operating performance.  In addition, a significant increase in inflation could 
increase our expenses more rapidly than expected, the effect of which may not be offset by corresponding increases 
in revenue. Conversely, deflation resulting in a decline of prices could reduce our revenues.  In the current economic 
environment, it is difficult to predict whether we will experience significant inflation or deflation in the near future.  
A  significant  increase  in  either  could  have  an  adverse  effect  on  our  results  of  operations.  As  a  result  of  current 
economic  conditions,  we  have  recently  seen  an  increase  in  customer  cancellations,  reductions  of  services  and 
failures to timely pay amounts due us.  If we experience greater cancellations and more reductions of services and 
failures to timely pay and we do not acquire new clients or sell new services to our existing clients, our revenues 
may decline and our financial position would be adversely affected.  

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/marketing services. Our 
subscription-based information/marketing services generate the largest portion of our revenues. However, we may 
be  unable  to  attract  new  clients,  and  our  existing  clients  may  decide  not  to  add,  not  to  renew  or  to  cancel 
subscription  services.  In  addition,  in  order  to  increase  our  revenue,  we  must  continue  to  attract  new  customers, 
continue to keep our cancellation rate low and continue to sell new services to our existing customers. We may not 
be able to continue to grow our customer base, keep the cancellation rate for customers and services low or sell new 
services  to  existing  customers  as  a  result  of  several  factors,  including  without  limitation:  economic  pressures,  a 
decision  that  customers  have  no  need  for  our  services;  a  decision  to  use  alternative  services;  customers’  and 
potential  customers’  pricing  and  budgetary  constraints;  consolidation  in  the  real  estate  and/or  financial  services 
industries; data quality; technical problems; or competitive pressures. 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. 

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 
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. 

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.                             
Recently, foreign currency exchange rates have fluctuated greatly and may continue to fluctuate.  Significant foreign 
currency  exchange  rate  fluctuations  may  negatively  impact  our  international  revenue,  which  in  turn  affects  our 
consolidated  revenue.    Currencies  may  be  affected  by  internal  factors,  general  economic  conditions  and  external 
developments in other countries, all of which can have an adverse impact on a country’s currency. Currently, we are 
not party to any hedging transactions intended to reduce our exposure to exchange rate fluctuations. We may seek to 
enter into hedging transactions in the future, but we may be unable to enter into these transactions successfully, on 
acceptable terms or at all. We cannot predict whether we will incur foreign exchange losses in the future. Further, 
significant foreign exchange fluctuations resulting in a decline in the British Pound or Euro may decrease the value 
of  our  foreign  assets,  as  well  as  decrease  our  revenues  and  earnings  from  our  foreign  subsidiaries,  which  would 
reduce our profitability and adversely affect our financial position. 

If  we  are  unable  to  sustain  our  revenue  growth  or  our  operating  costs  are  higher  than  expected,  our 
profitability may be reduced and our operating results may fluctuate significantly. We may not be able to accurately 
forecast  our  revenue  growth  rate.    Many  of  our  expenses,  particularly  personnel  costs  and  occupancy  costs,  are 
relatively fixed. As a result, we may not be able to adjust spending quickly enough to offset any unexpected increase 
in  expenses  or  revenue  shortfall.  We  may  experience  higher  than  expected  operating  costs,  including  increased 

15 

 
 
 
 
personnel  costs,  occupancy  costs,  selling  and  marketing  costs,  investments  in  geographic  expansion,  acquisition 
costs, communications costs, travel costs, software development costs, professional fees and other costs. If operating 
costs exceed our expectations and cannot be adjusted accordingly, our profitability may be reduced and our results 
of  operations  and  financial  position  will  be  adversely  affected.    Additionally,  we  may  not  be  able  to  sustain  our 
historic  revenue  growth  rates  and  our  percentage  revenue  growth  rates  may  decline.    Our  revenue  and  operating 
profit  growth  depend  on  continued  increased  demand  for  our  services.    Our  sales  are  affected  by,  among  other 
things,  general  economic  and  commercial  real  estate  conditions.    Reduced  demand,  whether  due  to  changes  in 
customer preference, a further weakening of the U.S. or global economies or other reasons, may result in decreased 
revenue and growth, adversely affecting our operating results. 

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

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 
make assurances that we will have any or sufficient insurance to cover any litigation claims. 

We may be subject to legal liability for collecting displaying or distributing information. Because the content in 
our database is collected from various sources and distributed to others, we may be subject to claims for breach of 
contract,  defamation,  negligence,  unfair  competition  or  copyright  or  trademark  infringement  or  claims  based  on 
other theories. We could also be subject to claims based upon the content that is accessible from our website through 
links to other websites or information on our website supplied by third parties. 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/marketing services to users. 

An impairment in carrying value of goodwill could negatively impact our consolidated results of operations and 
net  worth.  Goodwill  and  identifiable  intangible  assets  not  subject  to  amortization  are  tested  annually  by  each 
reporting unit on October 1st of each year for impairment and are tested for impairment more frequently based upon 
the  existence  of  one  or  more  indicators.    We  consider  our  operating  segments,  U.S.  and  International,  as  our 
reporting units under Statement of Financial Accounting Standards (“SFAS”) No. 142 for consideration of potential 
impairment  of  goodwill.  We  assess  the  impairment  of  long-lived  assets,  identifiable  intangibles  and  goodwill 
whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The existence 
of one or more of the following indicators could cause us to test for impairment prior to the annual assessment.   

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

These types of events or indicators and the resulting impairment analysis could result in goodwill impairment 
charges in the future, which would reduce our profitability. Impairment charges could negatively affect our financial 

16 

 
 
 
 
 
 
results in the periods of such charges, which may reduce our profitability. As of December 31, 2008, we had $54.3 
million of goodwill, $31.5 million in our U.S. segment and $22.8 million in our International segment. 

Our  stock  price  may  be  negatively  affected  by  fluctuations  in  our  financial  results.  Our  operating  results, 
revenues and expenses may fluctuate as a result of changes in 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  and  exchange  rate  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:  economic  factors;  quarter-to-quarter  variations  in  our  operating 
results;  changes  in  analysts’  estimates  of  our  earnings;  announcements  by  us  or  our  competitors  of  technological 
innovations  or  new  services;  general  conditions  in  the  commercial  real  estate  industry;  developments  or  disputes 
concerning copyrights or proprietary rights or other legal proceedings; and regulatory developments. In addition, 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. 

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

Negative  conditions  in  the  global  credit  markets  may  affect  the  liquidity  of  a  portion  of  our  long-term 
investments.  Currently our long-term investments include mostly AAA rated auction rate securities (“ARS”), which 
are  primarily  student  loan  securities  supported  by  guarantees  from  the  Federal  Family  Education  Loan  Program 
(“FFELP”)  of  the  U.S.  Department  of  Education.  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 December 31, 2008, we 
held $33.1 million par value of ARS all of which failed to settle at auctions. When an auction fails for ARS in which 
we have invested, we may be unable to liquidate some or all of these securities at par. In the event we need or desire 
to  immediately  access  these  funds,  we  will  not  be  able  to  do  so  until  a  future  auction  on  these  investments  is 
successful, a buyer is found outside the auction process or an alternative action is determined. If a buyer is found but 
is  unwilling  to  purchase  the  investments  at  par,  we  may  incur  a  loss,  which  would  reduce  our  profitability  and 
adversely affect our financial position. 

Our ARS  investments  are  not  currently  trading  and  therefore  do  not  currently  have  a  readily  determinable 
market value.  Accordingly, the estimated fair value of the ARS no longer approximates par value.  We have used a 
discounted  cash  flow  model  to  determine  the  estimated  fair  value  of  our  investment  in  ARS  as  of  December  31, 

17 

 
 
 
 
 
2008.  The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit 
spreads, timing and amount of cash flows, liquidity risk premiums, expected holding periods and default risk of the 
ARS.  Based on this assessment of fair value, as of December 31, 2008, we determined there was a decline in the 
fair  value  of  our  ARS  investments  of  approximately  $3.7  million.    The  decline  was  deemed  to  be  a  temporary 
impairment  and  recorded  as  an  unrealized  loss  in  other  comprehensive  income  in  stockholders’  equity.    If  the 
issuers of these ARS are unable to successfully close future auctions and their credit ratings deteriorate, we may be 
required  to  record  additional  unrealized  losses  in  other  comprehensive  income  or  an  other-than-temporary 
impairment charge to earnings on these investments, which would reduce our profitability and adversely affect our 
financial position. 

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/marketing 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  2009,  we  plan  to 
continue  to  increase  the  depth  of  our  coverage  in  the  U.S.  and  U.K.    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  imposed  and  continues  to  impose  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 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. 

We  may  not  be  able  to  successfully  introduce  new  or  upgraded  information/marketing  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/marketing 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 

18 

 
 
 
 
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. 

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

If  we  are  not  able  to  obtain  and  maintain  accurate,  comprehensive  or  reliable  data,  we  could  experience 
reduced  demand  for  our  information/marketing  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. Our U.S. researchers use integrated internal 
research  processes  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.   

If  we  are not able  to  successfully  identify, finance  and/or  integrate acquisitions,  our business operations and 
financial  position  could  be  adversely  affected.  We  have  expanded  our  markets  and  services  in  part  through 
acquisitions of complementary businesses, services, databases and technologies, and expect to continue to do so in 
the future. Our strategy to acquire complementary companies or assets depends on our ability to identify, and the 
availability of, suitable acquisition candidates. 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,  CoStar  U.K.  Limited  and  Propex  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.  Obtaining credit in the current economic 
environment may be difficult and cost prohibitive.  We may be unable to obtain financing on favorable terms, or at 
all,  if  necessary  to  finance  future  acquisitions  making  it  impossible  or  more  costly  to  acquire  complementary 
businesses.  If we are able to obtain financing, the terms may be onerous and more restrictive than we are willing to 
accept. 

Temporary or permanent outages of our computers, software or telecommunications equipment could lead to 
reduced demand for our information/marketing 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/marketing services to clients, we could experience reduced demand for our information/marketing 
services, lower revenues and increased costs. 

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 

19 

 
 
 
 
 
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.

Properties 

Our corporate headquarters is located in Bethesda, Maryland, where we occupy approximately 60,000 square 
feet  of  office  space.  Our  main  lease  for  our  Bethesda,  Maryland  headquarters  expires  on  March  31,  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; Indianapolis; and St. Louis.   

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

Item 3. 

Legal Proceedings 

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

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

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

All forward-looking statements are based on information available to us on the date of this filing and we assume 
no obligation to update such statements. 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 Group, Inc. (“CoStar”) is the number one provider of information/marketing services to the commercial 
real estate industry in the U.S. and the U.K. based on the fact that we offer the most comprehensive commercial real 
estate database available, have the largest research department in the industry, provide more information/marketing 
services than any of our competitors and believe we generate more revenues than any of our competitors. We have 
created a standardized information/marketing 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,  internet  marketing  services,  information  for  clients'  websites,  information  about  industry 
professionals and their business relationships, analytic information, data integration, 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/marketing services  and 
developed  new  information/marketing  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., a California-based provider of commercial real estate 
software.  In September 2002, we expanded further into Portland, Oregon through the acquisition of certain assets of 
Napier Realty Advisors (doing business as 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 (“SPN”). 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  Connecticut-based  leading  provider  of 
U.S. shopping center information. 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  electronic  platform  that 
facilitates the exchange of investment property located in London, England. In April 2008, we acquired the assets of 
First  CLS,  Inc.  (doing  business  as  the  Dorey  Companies  and  DoreyPRO),  an  Atlanta-based  provider  of  local 
commercial  real  estate  information.  The  more  recent  acquisitions  are  discussed  later  in  this  section  under  the 
heading “Recent Acquisitions.” 

24 

 
 
 
 
 
 
  
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. We completed our expansion into the 21 
new  markets  in  the  first  quarter  of  2006.  In  early  2005,  in  conjunction  with  the  acquisition  of  National  Research 
Bureau,  we  launched  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, to expand the geographical coverage of our service offerings 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  connection  with  our  acquisitions  of  Propex  and  Grecam,  we  intend  to  expand  the  coverage  of  our  service 
offerings  within  the  U.K.  and  integrate  our  international  operations  more  fully  with  those  of  the  U.S. We  have 
gained 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. 

We  intend  to  eventually  introduce  a  consistent  international  platform  of  service  offerings.  In  2007,  we 
introduced the “CoStar Group” as the brand encompassing our international operations. We believe that our recent 
U.S. and international expansion and integration efforts have created a platform for earnings. In fact, our results for 
2008 reflect growth in earnings as a result of these investments in our business.   

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

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. For instance, 
in  May  2008,  we  released  CoStar  Showcase®,  an  internet  marketing  service  that  provides  commercial  real  estate 
professionals the opportunity to make their listings accessible to all visitors to our public website, www.CoStar.com. 
In addition, in April 2008, as described above we acquired the online commercial real estate information assets of 
First CLS, Inc. (doing business as the Dorey Companies and DoreyPRO). Any future expansion could reduce our 
profitability  and  increase our  capital  expenditures.  Therefore,  while we expect  current  service  offerings  to remain 
profitable,  driving  overall  earnings  throughout  2009  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. 

  Current general economic conditions in the U.S. and the world are negatively affecting business operations for 
our clients and are resulting in more business consolidations and, in certain circumstances, failures. As a result of the 
economic conditions, we have recently seen an uptick in customer cancellations, reductions of services and failures 
to  pay  amounts  due  us.    If  cancellations,  reductions  of  services  and  failures  to  pay  continue  to  rise,  and  we  are 
unable to offset the resulting decrease in revenue by increasing sales to new or existing customers, our revenues will 
be adversely affected and our revenue may decline.  Additionally, current conditions may cause customers to reduce 
expenses, when reducing expenses, customers may be forced to purchase fewer services or cancel all services.  We 
compete  against  many  other  commercial  real  estate  information/marketing  service  providers  for  business.    If 
customers choose to cancel our services for cost-cutting or other reasons, our revenue could decline.  The extent and 
duration of any future continued weakening of the economy is unknown and there can be no assurance that any of 
the governmental or private sector initiatives designed to strengthen the economy will be successful.  Because of the 
current  uncertainties  in  the  economic  environment,  we  may  not  be  able  to  accurately  forecast  our  revenue.  

25 

 
 
 
 
 
  
However, we continue to believe that the company is positioned to generate continued, sustained earnings through 
the end of 2009. 

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 
$4.9 million in total equity compensation expense in 2008. 

Our  subscription-based  information/marketing  services,  consisting  primarily  of  CoStar  Property  Professional, 
CoStar Tenant, CoStar COMPS Professional, and FOCUS services currently generate more than 90% of our total 
revenues.  CoStar  Property  Professional,  CoStar  Tenant,  and  CoStar  COMPS  Professional  are  generally  sold  as  a 
suite of similar services and comprise our primary service offering in our U.S. operating segment.  FOCUS is our 
primary  service  offering  in  our  International  operating  segment.  Our  contracts  for  our  subscription-based 
information/marketing 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 generally 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 year ended December 31, 2007, our contract renewal rate was over 90%.  For the year ended December 
31,  2008,  our  contract  renewal  rate  was  approximately  89%.    As  discussed  above,  our  contract  renewal  rate  may 
continue to decline if continuing negative economic conditions lead to business failures and/or consolidations and 
further reductions in customer spending and decreases in the customer base. 

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 management 
relate to the expected useful lives of long-lived assets and our ability to realize any undiscounted cash flows of the 
carrying  amounts  of  such  assets.    The  accuracy  of  these  judgments  may  be  adversely  affected  by  several  factors, 
including the factors listed below: 

•  Significant underperformance relative to historical or projected future operating results;  
•  Significant changes in the manner of our use of 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.  

26 

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

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

Goodwill and identifiable intangible assets not subject to amortization are tested annually by each reporting unit 
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  consider  our  operating  segments,  U.S.  and  International,  as  our 
reporting units under Statement of Financial Accounting Standards (“SFAS”) No. 142 for consideration of potential 
impairment of goodwill.  

The  goodwill  impairment  test  is  a  two-step  process.    The  first  step  is  to  determine  the  fair  value  of  each 
reporting unit. We estimate the fair value of each reporting unit based on a projected discounted cash flow model 
that  includes  significant  assumptions  and  estimates  including  our  future  financial  performance  and  a  weighted 
average  cost of  capital.  The fair value  of  each reporting unit  is  compared  to  the  carrying  amount of  the reporting 
unit.  If  the  carrying  value  of  the  reporting  unit  exceeds  the  fair  value,  then  the  second  step  of  the  process  is 
performed to measure the impairment loss.  We measure impairment loss based on a projected discounted cash flow 
method  using  a  discount  rate  determined  by  our  management  to  be  commensurate  with  the  risk  in  our  current 
business model. 

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.  

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  on  a  consolidated  and  an  operating  segment  basis  in  our 
earnings  releases,  investor  conference  calls  and  filings  with  the  Securities  and  Exchange  Commission.  The  non-
GAAP  financial  measures  that  we  use  may  not  be  comparable  to  similarly  titled  measures  reported  by  other 
companies.  Also,  in  the  future,  we  may  disclose  different  non-GAAP  financial  measures  in  order  to  help  our 
investors 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 

27 

 
 
 
 
 
 
 
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 21 years building 
our  database  of  commercial  real  estate  information  and  expanding  our  markets  and  services  partially  through 
acquisitions  of  complementary  businesses.  Due  to  the  expansion  of  our  information/marketing  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, 2008 and Year Ended December 31, 2007 

Revenues. Revenues grew to $212.4 million in 2008, from $192.8 million in 2007. This increase in revenue was 
due to further penetration of our subscription-based information/marketing services, and successful cross-selling of 
our services to our customers 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,  FOCUS  services  and  Propex  services.  As  of  December  31,  2008,  our  subscription-based 
information/marketing services represented more than 90% of our total revenues.

Gross  Margin.  Gross  margin  increased  to  $139.0  million  in  2008,  from  $116.1  million  in  2007.  The  gross 
margin  percentage  increased  to  65.4%  in  2008,  from  60.2%  in  2007.  The  increase  in  the  gross  margin  resulted 
principally from revenue growth from our subscription-based information/marketing services and a decrease in cost 
of revenues. Cost of revenues decreased to $73.4 million for the year ended December 31, 2008, from $76.7 million 
for the year ended December 31, 2007 principally due to expansion costs that were incurred in 2007 that were not 
incurred in 2008. 

Selling  and  Marketing  Expenses.  Selling  and  marketing  expenses  decreased  to  $41.7  million  in  2008,  from 
$51.8  million  in  2007,  and  decreased  as  a  percentage  of  revenues  to  19.6%  in  2008,  from  26.9%  in  2007.  The 
decrease was principally due to a reduction in personnel costs of approximately $5.4 million primarily due to the 
fact that the sales force sold services with a smaller average price point in 2008, which resulted in lower average 
contract values compared to 2007. Additionally, there was a decrease in marketing initiatives of approximately $2.3 
million in 2008. 

Software Development Expenses. Software development expenses slightly increased to $12.8 million in 2008, 
from $12.5 million in 2007, and slightly decreased as a percentage of revenues to 6.0% in 2008, from 6.5% in 2007.  
The decrease in the percentage was primarily due to increased revenues in 2008. 

General and Administrative Expenses. General and administrative expenses increased to $39.9 million in 2008, 
from $36.6 million in 2007, and decreased slightly as a percentage of revenues to 18.8% in 2008, from 19.0% in 
2007. The increase in the amount of general and administrative expenses was principally a result of an increase of 
approximately $2.5 million in legal fees and an increase of $1.6 million in bad debt expense.   

Gain on Lease Settlement, Net. On September 14, 2007, CoStar U.K Limited, a wholly owned U.K. subsidiary 
of  CoStar,  entered  into  an  agreement  with  Trafigura  Limited  to  assign  to  Trafigura  our  leasehold  interest  in  our 
office space located in London. The lease assignment was effective on December 19, 2007. As a result, CoStar U.K. 
Limited  was  paid  $7.6  million,  net  of  expenses,  for  the  assignment  of  the  lease.  There  were  no  gains  on  lease 
settlements in 2008.   

Purchase Amortization. Purchase amortization slightly decreased to $4.9 million in 2008, from $5.1 million in 

2007, and slightly decreased as a percentage of revenues to 2.3% in 2008, from 2.6% in 2007. 

Interest  and  Other  Income,  Net.  Interest  and  other  income,  net  decreased  to  $4.9  million  in  2008,  from  $8.0 
million  in  2007.  Although,  cash  and  cash  equivalents,  short-term  and  long-term  investments  were  higher  in  2008 
than in 2007, our interest and other income decreased due to lower average interest rates in 2008 compared to 2007. 

Income  Tax  Expense,  Net.  Income  tax  expense,  net  increased  to  $20.1  million  in  2008,  from  $9.9  million  in 
2007.  This  increase  was  primarily  due  to  higher  income  before  income  taxes  for  2008  due  to  our  growth  and 
profitability, in addition to a higher effective tax rate in 2008.  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, 2008 and Year Ended December 31, 
2007 

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  segment  revenue  and  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 
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.  CoStar  Property  Professional,  CoStar  Tenant,  and  CoStar  COMPS  Professional  are 
generally sold as a suite of similar services and comprise our primary service offering in our U.S. operating segment. 
U.S. revenues increased to $190.1 million from $170.3 million for the years ended December 31, 2008 and 2007, 
respectively.  This  increase  in  U.S.  revenue  is  due  to  further  penetration  of  our  U.S.  subscription-based 
information/marketing  services  and  the  successful  cross-selling  of  our  service  to  our  customers,  combined  with  a 
continued  high  renewal  rate.  FOCUS  is  our  primary  service  offering  in  our  International  operating  segment.  
International  revenues  slightly  decreased  to  $22.4  million  from  $22.5  million  for  the  years  ended  December  31, 
2008  and  2007,  respectively.  This  decrease  is  due  to  foreign  currency  fluctuations.    In  their  functional  currency, 
International revenues increased 7.2% for the year ended December 31, 2008 compared to the year ended December 
31, 2007. 

Segment EBITDA. U.S. EBITDA increased to $58.8 million from $32.9 million for the years ended December 
31, 2008 and 2007, respectively. The increase in U.S. EBITDA was due to increased revenues, and lower sales and 
marketing personnel costs, partially offset by an increase in legal fees and bad debt expense. International EBITDA 
decreased  to  a  loss of $2.2 million  from  $1.1  million  earnings for  the  years  ended December 31,  2008  and 2007, 
respectively. This decrease is primarily due to gain on lease settlement of $7.6 million in 2007 that did not occur in 
2008. International EBITDA also includes a corporate allocation of approximately $1.1 million and $2.6 million for 
the years ended December 31, 2008 and 2007, respectively. The corporate allocation represents costs incurred for 
U.S. employees involved in international management and expansion activities. 

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 
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 U.K. Limited, a wholly owned U.K. subsidiary 
of  CoStar,  entered  into  an  agreement  with  Trafigura  Limited  to  assign  to  Trafigura  our  leasehold  interest  in  our 
office space located in London. The lease assignment was effective on December 19, 2007. As a result, CoStar U.K. 
Limited  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 
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.

Recent Acquisitions 

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  and  21,526 
shares of CoStar common stock. 

First  CLS,  Inc.  On  April  1, 2008, we  acquired  certain  assets  of  First  CLS,  Inc. (doing  business  as  the  Dorey 
Companies and DoreyPRO), an Atlanta-based provider of local commercial real estate information for $3.0 million 
in  initial  cash  consideration  and  deferred  consideration  payable  within  approximately  six  months  of  the  one-year 
anniversary of closing.  

Accounting  Treatment.  These  acquisitions  were  accounted  for  using  purchase  accounting.  The  purchase  price 
for  the  Propex  acquisition  was  primarily  allocated  to  acquired  customer  base,  trade  names,  and  goodwill.  The 
purchase price for the First CLS, Inc. acquisition was primarily allocated to acquired customer base.  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 Propex acquired trade name is being amortized on a straight-line basis

over three years.  We recorded goodwill of approximately $15.0 million for the Propex acquisition and $1.1 million 
for the First CLS, Inc. acquisition. Goodwill is not amortized, but is subject to annual impairment tests. The results 
of operations of Propex and First CLS, Inc. have been consolidated with those of the Company since the respective 
dates of the acquisitions and are not considered material to our consolidated financial statements. 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 $195.3 million at December 31, 2008 compared to $187.4 million at 
December 31, 2007. The increase in cash, cash equivalents and short-term investments for the year ended December 
31, 2008 was primarily due to net cash from operating activities of approximately $40.9 million partially offset by 
the  reclassification  of  approximately  $33.1  million  par  value  auction  rate  securities  (“ARS”)  from  short-term 
investments to long-term investments in the first quarter of 2008. 

Net cash provided by operating activities for the year ended December 31, 2008 was $40.9 million compared to 
$51.7 million for the year ended December 31, 2007. The $10.8 million decrease in net cash provided by operating 
activities  is  primarily  due  to  approximately  $3.3  million  decreased  cash  receipts  on  accounts  receivable  due  to 
increased  balances  and  declining  economic  conditions  and  increased  payments  for  accounts  payable  and  accrued 
expenses of approximately $9.8 million which included the $2.9 million payment of deferred consideration for the 
Propex  acquisition,  approximately  $400,000  in  payments  for  a  Propex  data  agreement,  and  payment  of 
approximately $1.4 million in value added taxes related to the lease settlement. 

Net cash provided by investing activities was $52.4 million for the year ended December 31, 2008, compared to 
net  cash  used  in  investing  activities  of  $40.3  million  for  the  year  ended  December  31,  2007.  This  $92.7  million 
increase  in  net  cash  provided  by  investing activities  was  primarily  due  to  the  decision  to  invest  in  money  market 
funds and U.S. treasuries instead of short-term investment instruments, which resulted in a net sale of investments of 
approximately  $59.1  million  in  the  year  ended  December 31,  2008  compared  to  a  net purchase  of  investments  of 
approximately  $9.3  million  in  the  year  ended  December  31,  2007.    In  addition,  we  used  $3.0  million  in  cash  as 
initial consideration for the purchase of First CLS, Inc. in the year ended December 31, 2008, as compared to $16.7 
million  in  cash  consideration  used  for  the  acquisition  of  Propex  in  the  year  ended  December  31,  2007.  We  also 
purchased approximately $10.6 million less in property, equipment and other assets during the year ended December 
31, 2008 compared to the year ended December 30, 2007. 

Net cash provided by financing activities was $11.5 million for the year ended December 31, 2008 compared to 
$8.2 million for the year ended December 31, 2007.  The higher net cash provided by financing activities in 2008 
compared to 2007 is due to an increase in excess tax benefits from stock options partially offset by a decrease in 
proceeds from the exercise of stock options. 

Contractual Obligations. The following table summarizes our principal contractual obligations at December 31, 
2008  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 (i) contracts with initial terms of twelve months or less, or (ii) multi-year contracts that may be 
terminated by a third party or us. 

During  2008,  we  incurred  capital  expenditures  of  approximately  $3.7  million.  We  expect  to  make  capital 

expenditures in 2009 of approximately $4.0 million to $7.0 million.

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.  In April 2008, we paid $3.0 million in initial cash consideration 
and  made  a  commitment  for  deferred  consideration  payable  within  approximately  six  months  of  the  one-year 
anniversary of closing for the online commercial real estate information assets of First CLS, Inc., an Atlanta-based 
provider of local commercial real estate information.  

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

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

As of December 31, 2008, we had $33.1 million of long-term investments in student loan ARS, which failed to 
settle  at  auctions.    The  majority  of  these  investments  are  of  high  credit  quality  with  AAA  credit  ratings  and  are 
primarily  securities  supported  by  guarantees  from  the  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. 

As of December 31, 2008, we had utilized all of our U.S. net operating loss carryforwards for federal income 
tax purposes.  As a result, we expect our cash payments for taxes to be approximately $20.0 million to $23.0 million 
in 2009.  

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 2009. 

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.   In  February  2008,  the  FASB  issued 
FASB  Staff  Position  (“FSP”)  157-2,  “Partial  Deferral  of  the  Effective  Date  of  Statement  157”,  (“FSP  157-2”), 
which  delays  the  effective  date  of  SFAS  157  to  January  1,  2009  for  all  non-financial  assets  and  non-financial 
liabilities, except those that are recognized or disclosed at fair value in the consolidated financial statements on a 
recurring  basis  (at  least  annually).  Effective  January  1,  2008,  we  adopted  the  portion  of  SFAS  157  that  was  not 
deferred under FSP 157-2.  The adoption of SFAS 157 did not have a material impact on our results of operations 
and financial position.  In October 2008, the FASB issued FSP 157-3, “Determining the Fair Value of a Financial 
Asset in a Market That Is Not Active” (“FSP 157-3”), which clarifies the application of SFAS 157 to markets that are 
not active and provides an example illustrating key considerations for determining the fair value of financial assets 
when  their  markets  are  not  active.  FSP  157-3  was  effective  upon  issuance,  including  prior  periods  for  which 
financial  statements  had  not  been  issued.  The  adoption  of  this  standard  did  not  have  an  impact  on  our  results  of 
operations or financial position. 

35 

 
 
 
 
 
 
 
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  that  are  not  currently  required  to  be 
measured at fair value. SFAS 159 is effective for fiscal years beginning on or after December 31, 2007. We adopted 
SFAS  159  on  January  1,  2008  and  have  not  elected  to  apply  the  fair  value  option  to  any  of  our  financial 
instruments.  The adoption of SFAS 159 did not have a material impact on our results of operations and 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 depend upon the specifics of any 
business combination with an acquisition date subsequent to December 31, 2008. 

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 
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. 

In April 2008, the FASB issued FSP SFAS No. 142-3, “Determination of the Useful Life of Intangible Assets” 
(“FSP 142-3”), which is effective for all fiscal years and interim periods beginning after December 15, 2008. Early 
adoption of FSP 142-3 is not permitted. FSP 142-3 requires additional footnote disclosures about the impact of our 
ability  or  intent  to  renew  or  extend  agreements  related  to  existing  intangibles  or  expected  future  cash  flows  from 
those  intangibles,  how  we  account  for  costs  incurred  to  renew or  extend  such  agreements,  the  time  until  the  next 
renewal or extension period by asset class, and the amount of renewal or extension costs capitalized, if any. For any 
intangibles  acquired  after  December  31,  2008,  FSP  142-3  requires  that  we  consider  our  experience  regarding 
renewal  and  extensions of  similar  arrangements  in  determining  the useful  life. If we do not  have  experience with 
similar arrangements, FSP 142-3 requires that we use the assumptions of a market participant putting the intangible 
to its highest and best use in determining the useful life. The adoption of FSP 142-3 will impact intangibles acquired 
after December 31, 2008, and its effect will depend on the specifics of the intangible acquired. 

In May 2008, the FASB issued SFAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles” 
(“SFAS 162”), which identifies the sources of accounting principles and the framework for selecting the principles 
to be used in the preparation of financial statements. SFAS 162 is effective as of November 17, 2008. The adoption 
of SFAS 162 did not have a material impact on our results of operations or financial position. 

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk  

We provide information/marketing services to the commercial real estate and related business community in the 
U.S., 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.  For  the  year  ended  December  31,  2008,  revenue  denominated  in  foreign  currencies  was 
approximately 11% of total revenue.  For the year ended December 31, 2008, our revenue would have decreased by 
approximately $2.2 million if the U.S. dollar exchange rate used strengthened by 10%.  In addition, we have assets 
and liabilities denominated in foreign currencies.  A 10% strengthening of the U.S. dollar exchange rate against all 
currencies with which we have exposure at December 31, 2008 would have resulted in a decrease of approximately 
$340,000  in  the  carrying  amount  of  net  assets.  For  the  year  ended  December  31,  2008,  our  revenue  would  have 
increased by approximately  $2.2 million if the U.S. dollar exchange rate used weakened by 10%. In addition, we 
have assets and liabilities denominated in foreign currencies.  A 10% weakening of the U.S. dollar exchange rate 
against  all  currencies  with  which  we  have  exposure  at  December  31,  2008  would  have  resulted  in  a  increase  of 
approximately $340,000 in the carrying amount of net assets. We currently do not use financial instruments to hedge 
our exposure to exchange rate fluctuations with respect to our foreign subsidiaries. We may seek to enter hedging 

36 

 
 
 
 
 
 
 
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,  2008,  accumulated  other 
comprehensive income (loss) included a loss from foreign currency translation adjustments of approximately $8.5 
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, 2008.  As of December 31, 2008, we had $195.3 million of cash, cash 
equivalents  and short-term  investments.    If  there  is  an  increase  or  decrease  in  interest  rates,  there  will  be  a 
corresponding  increase  or  decrease  in  the  amount  of  interest  earned  on  our  cash,  cash  equivalents  and short-term 
investments.  Based on our ability to access our cash, cash equivalents and short-term investments, and our expected 
operating cash flows, we do not believe that increases or decreases in interest rates will impact our ability to operate 
our business in the foreseeable future. 

Included  within  our  long-term  investments  are  investments  in  mostly  AAA  rated  student  loan  ARS.    These 
securities  are primarily  securities  supported  by  guarantees  from  the  FFELP  of  the  U.S.  Department  of  Education.  
As of December 31, 2008, auctions for $33.1 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.  Based on an assessment of 
fair value of these investments in ARS as of December 31, 2008, we determined that there was a decline in the fair 
value of our ARS investments of approximately $3.7 million, which was deemed to be a temporary impairment and 
recorded as an unrealized loss in other comprehensive income in stockholders’ equity.  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  as  a  temporary  impairment  and  recognize  a  greater  unrealized  loss  in  other  comprehensive 
income or as an other-than-temporary impairment charge to earnings. Based on our ability to access our cash, cash 
equivalents and 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 approximately $70.7 million in intangible assets as of December 31, 2008. As of December 31, 2008, 
we believe our intangible assets will be recoverable, however, changes in the economy, the business in which we 
operate  and  our  own  relative  performance  could  change  the  assumptions  used  to  evaluate  intangible  asset 
recoverability. In the event that we determine that an asset has been impaired, we would recognize an impairment 
charge  equal  to  the  amount  by  which  the  carrying  amount  of  the  assets  exceeds  the  fair  value  of  the  asset.  We 
continue to monitor these assumptions and their effect on the estimated recoverability of our intangible assets.

Financial Statements and Supplementary Data 

Financial  Statements  meeting  the  requirements  of  Regulation  S-X  are  set  forth  beginning  at  page  F-1. 
Supplementary data is set forth in “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations” under the caption “Consolidated Results of Operations.” 

Item 9. 

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

None.  

Item 9A.  Controls and Procedures 

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

37 

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

As of December 31, 2008, 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. 

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, 2008 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, 2008. 

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, 2008 
and 2007, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the 
three  years  in  the  period  ended  December  31,  2008.  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,  2008  and  2007,  and  the  consolidated  results  of  its 
operations and its cash flows for each of the three years in the period ended December 31, 2008, in conformity with 
U.S. generally accepted accounting principles.  

As  also  discussed  in  Note  9  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,  2008,  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 19, 2009 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, 
2008,  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, 2008, 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,  2008  and  2007  and  the  related  consolidated 
statements  of  operations,  stockholders’  equity  and  cash  flows  for  each  of  the  three  years  in  the  period  ended 
December 31, 2008 of CoStar Group, Inc. and our report dated February 19, 2009 expressed an unqualified opinion 
thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

December 31, 2008 

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/marketing  services  to  the  commercial  real  estate  and  related 
business  community  and  operates  within 
International.  The  Company’s 
information/marketing services are typically distributed to its clients under subscription-based license agreements, 
which typically have a minimum term of one year and renew automatically. 

two  segments,  U.S.  and 

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  of America  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. 

Reclassifications 

Certain previously reported amounts have been reclassified to conform to the Company’s current presentation. 

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/marketing  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, 2006, 2007 and 2008.

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. Revenues, expenses, gains and losses are translated at the 
average  exchange  rates  in  effect  during  each  period.  Gains  and  losses  resulting  from  translation  are  included  in 
accumulated other comprehensive income. Net gains or losses resulting from foreign currency exchange transactions 
are  included  in  the  consolidated  statements  of  operations.  There  were  no  material  gains  or  losses  from  foreign 
currency exchange transactions for the years ended December 31, 2008 and 2007. 

Comprehensive Income 

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

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

$2.3 million and $2.8 million for the years ended December 31, 2006, 2007 and 2008, 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  generally  requires  that 
equity instruments 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ⎯ (CONTINUED) 

Stock-Based Compensation ⎯  (Continued) 

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. 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. 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 ................................................................................................................................... $ 
Basic earnings per share............................................................................................................... $ 
Diluted earnings per share............................................................................................................ $ 

(2,860) 
(2,860) 
(1,784) 
(0.10) 
(0.09) 

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 consolidated statement of cash flows.  Net cash proceeds from the exercise of stock options 
were approximately $6.6 million; $8.1 million and $6.6 million for the years ended December 31, 2006, 2007 and 
2008,  respectively.    There  were  approximately  $5.3  million  of  excess  tax  benefits  realized  from  stock  option 
exercises for the year ended December 31, 2008. 

Stock-based  compensation  expense  for  stock  options,  restricted  stock  and  the  employee  stock  purchase  plan 

included in the Company's results of operations for the years ended December 31, was as follows (in thousands):

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  U.S.  Government 
Securities. As of December 31, 2007 and 2008, cash of $754,000 and $518,000, respectively, was held to support 
letters of credit for security deposits. 

Investments 

The Company accounts for 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.    Short-term 
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 short-term 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. Long-term investments consist of auction 
rate securities.  Investments are carried at fair market value. 

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, long-term investments, accounts receivable, accounts payable, and accrued expenses approximates fair 
value. 

Allowance for Doubtful Accounts 

The  allowance  for doubtful  accounts  is  based  on  the  Company’s  assessment  of  the  collectability  of  customer 
accounts.  The Company regularly reviews the allowance by considering factors such as historical experience, the 
aging of the balances, and current economic conditions that may affect a customer’s ability to pay.  

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 by reporting unit in accordance with the provisions 
of SFAS No. 142. The goodwill impairment test is a two-step process.  The first step is to determine the fair value of 
each reporting unit.  The estimate of the fair value of each reporting unit is based on a projected discounted cash 
flow  model  that  includes  significant  assumptions  and  estimates  including  our  future  financial  performance  and  a 
weighted  average  cost of  capital.  The  fair value  of  each reporting  unit is  compared  to  the  carrying  amount  of  the 
reporting unit. If the carrying value of the reporting unit exceeds the fair value, then the second step of the process is 
performed to measure the impairment loss.    The impairment loss is measured based on a projected discounted cash 
flow method using a discount rate determined by our management to be commensurate with the risk in our current 
business model. 

 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 by reporting unit, 
and are tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. 
The Company’s operating segments, U.S. and International, are the reporting units tested for potential impairment 
under SFAS No. 142. 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.   In  February  2008,  the  FASB  issued 
FASB Staff Position (“FSP”) 157-2, “Partial Deferral of the Effective Date of Statement 157” (“FSP 157-2”), which 
delays the effective date of SFAS 157 to January 1, 2009 for all non-financial assets and non-financial liabilities, 
except  those  that  are  recognized  or  disclosed  at  fair  value  in  the  consolidated  financial  statements  on  a  recurring 
basis (at  least annually).   Effective  January  1, 2008,  the Company  adopted  the portion of  SFAS 157  that  was not 
deferred under FSP 157-2.  The adoption of SFAS 157 did not have a material impact on the Company’s results of 
operations or financial position.  In October 2008, the FASB issued FSP 157-3, “Determining the Fair Value of a 
Financial  Asset  in  a  Market  That  Is  Not  Active”  (“FSP  157-3”),  which  clarifies  the  application  of  SFAS  157  to 
markets that are not active and provides an example illustrating key considerations for determining the fair value of 
financial assets when their markets are not active. FSP 157-3 was effective upon issuance, including prior periods 
for  which  financial  statements  had  not  been  issued.  The  adoption  of  this  standard  did  not  have  an  impact  on  the 
Company’s 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  that  are  not  currently  required  to  be 
measured  at  fair  value.  SFAS  159  is  effective  for  fiscal  years  beginning  on  or  after  December  31,  2007.  The 
Company  adopted  SFAS  159  on  January  1,  2008  and  has  elected  not  to  apply  the  fair  value  option  to  any  of  its 
financial  instruments.    The  adoption  of  SFAS  159  did  not  have  a  material  impact  on  the  Company’s  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 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  depend  upon  the 
specifics of any business combination with an acquisition date subsequent to December 31, 2008. 

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 
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 Company’s results of operations or financial position.

Recent Accounting Pronouncements ⎯  (Continued) 

In April 2008, the FASB issued FSP SFAS No. 142-3, “Determination of the Useful Life of Intangible Assets” 
(“FSP 142-3”), which is effective for all fiscal years and interim periods beginning after December 15, 2008. Early 
adoption of FSP 142-3 is not permitted. FSP 142-3 requires additional footnote disclosures about the impact of the 
Company’s  ability  or  intent  to  renew or  extend  agreements related  to  existing  intangibles  or  expected  future  cash 
flows from those intangibles, how the Company accounts for costs incurred to renew or extend such agreements, the 
time  until  the  next  renewal  or  extension  period  by  asset  class,  and  the  amount  of  renewal  or  extension  costs 
capitalized,  if  any.  For  any  intangibles  acquired  after  December  31,  2008,  FSP  142-3  requires  that  the  Company 
consider its experience regarding renewal and extensions of similar arrangements in determining the useful life of 
such intangibles. If the Company does not have experience with similar arrangements, FSP 142-3 requires that the 
Company  use  the  assumptions  of  a  market  participant  putting  the  intangible  to  its  highest  and  best  use  in 
determining the useful life. The adoption of FSP 142-3 will impact intangibles acquired after December 31, 2008, 
and its effect will depend on the specifics of the intangible acquired. 

In May 2008, the FASB issued SFAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles” 
(“SFAS 162”), which identifies the sources of accounting principles and the framework for selecting the principles 
to be used in the preparation of financial statements. SFAS 162 is effective as of November 17, 2008. The adoption 
of SFAS 162 did not have a material impact on the Company’s results of operations or financial position. 

3. ACQUISITIONS 

On  February 16,  2007,  CoStar  Limited,  a  wholly  owned  U.K.  subsidiary  of  CoStar,  acquired  all  of  the 
outstanding capital stock of Property Investment Exchange Limited (“PropexTM”) for approximately $22.0 million, 
consisting of cash, deferred consideration 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. 

On  April  1,  2008,  the  Company  acquired  certain  assets  of  First  CLS,  Inc.  (doing  business  as  the  Dorey 
Companies and DoreyPRO), an Atlanta-based provider of local commercial real estate information for $3.0 million 
in  initial  cash  consideration  and  deferred  consideration  payable  within  approximately  six  months  of  the  one-year 
anniversary of closing.  

These  acquisitions  were  accounted  for  using  the  purchase  method  of  accounting.  The  purchase  price  of  the 
Propex acquisition was primarily allocated to customer base, trade name, and goodwill. The purchase price of the 
First CLS, Inc. acquisition was primarily allocated to acquired customer base.  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 Propex acquired trade name is amortized on a straight-line basis over three years. We recorded 
goodwill  of  approximately  $15.0  million  for  the  Propex  acquisition  and  $1.1  million  for  the  First  CLS,  Inc. 
acquisition.  Goodwill is not amortized, but is subject to annual impairment tests. The results of operations of Propex 
and First CLS, Inc. have been consolidated with those of the Company since the date of the acquisition and are not 
considered material to our consolidated financial statements. Accordingly, pro forma financial information has not 
been presented for either acquisition.

4. INVESTMENTS 

The Company accounts for 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.    Short-term 
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 short-term 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. Long-term investments consist of auction 
rate securities.  Investments are carried at fair market value. 

Scheduled maturities of investments classified as available-for-sale as of December 31, 2008 are as follows (in 

thousands):

The  realized  gains  on  the  Company’s  investments  for  the  years  ended  December  31,  2007  and  2008  was 
approximately $24,000 and $329,000, respectively.  The realized losses on the Company’s investments for the years 
ended December 31, 2007 and 2008 was approximately $232,000 and $489,000, respectively. 

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,  2007  and  2008  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, 2007 and 
2008.

5. FAIR VALUE 

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. The  Company  adopted  the  provisions  of  SFAS  157  as  of  January  1,  2008  for 
financial instruments.  Although the adoption of SFAS 157 did not materially impact its financial position, results of 
operations,  or  cash  flow,  the  Company  is  now  required  to  provide  additional  disclosures  as  part  of  its  financial 
statements.

5. FAIR VALUE ⎯ (CONTINUED) 

SFAS  157  establishes  a  three-tier  fair  value  hierarchy,  which  categorizes  the  inputs  used  in  measuring  fair 
value.  These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, 
defined  as  inputs  other  than  quoted  prices  in  active  markets  that  are  either  directly  or  indirectly  observable;  and 
Level  3,  defined  as  unobservable  inputs  in  which  little  or  no  market  data  exists,  therefore  requiring  an  entity  to 
develop its own assumptions. 

In accordance with SFAS 157, the following table represents the Company's fair value hierarchy for its financial 
assets (cash, cash equivalents and investments) measured at fair value on a recurring basis as of December 31, 2008 
(in thousands):

The  Company’s  Level  2  assets  consist  of  corporate  debt  securities  and  government-sponsored  enterprise 
obligations, which do not have directly observable quoted prices in active markets.  The Company’s corporate debt 
securities are valued using matrix pricing, which is an acceptable practical expedient under SFAS 157 for inputs. 

The Company’s Level 3 assets consist of variable rate debt instruments with an auction-reset feature, Auction 
Rate Securities (“ARS”), whose underlying assets are primarily student loan securities supported by guarantees from 
the FFELP of the U.S. Department of Education.  

The  following  table  presents  the  Company’s  Level  3  assets  measured  at  fair  value  on  a  recurring basis  using 

significant unobservable inputs as defined in SFAS 157, as of December 31, 2008 (in thousands):

ARS  are  variable  rate  debt  instruments  whose  interest  rates  are  reset  approximately  every  28  days.  The 
underlying  securities  have  contractual  maturities  greater  than  twenty  years.  The  ARS  are  recorded  at  fair 
value.  Typically, the carrying value of ARS approximates fair value due to frequent resetting of the interest rates. 

As of December 31, 2008, the Company held ARS with $33.1 million par value, all of which failed to settle at 
auctions.  The  majority  of  these  investments  are  of  high  credit  quality  with  AAA  credit  ratings and  are  primarily 
student  loan  securities  supported  by  guarantees  from  the  FFELP of  the  U.S.  Department  of  Education.  The 
Company may not be able to liquidate and fully recover the carrying value of the ARS in the near term.  As a result, 
these securities are classified as long-term investments in the Company’s consolidated balance sheet as of December 
31, 2008.

5. FAIR VALUE ⎯ (CONTINUED) 

While the Company continues to earn interest on its ARS investments at the maximum contractual rate, these 
investments  are  not  currently  trading  and  therefore  do  not  currently  have  a  readily  determinable  market  value.  
Accordingly,  the  estimated  fair  value  of  the  ARS  no  longer  approximates  par  value.    The  Company  has  used  a 
discounted cash flow model to determine the estimated fair value of its investment in ARS as of December 31, 2008.  
The  assumptions  used  in  preparing  the  discounted  cash  flow  model  include  estimates  for  interest  rates,  credit 
spreads,  timing  and  amount  of  cash  flows,  liquidity  risk  premiums,  expected  holding  periods,  and  default  risk.  
Based on this assessment of fair value, as of December 31, 2008, the Company determined there was a decline in the 
fair  value  of  its  ARS  investments  of  approximately  $3.7  million.    The  decline  was  deemed  to  be  a  temporary 
impairment and recorded as an unrealized loss in other comprehensive income in stockholders’ equity.  In addition, 
while a majority of the ARS are currently rated AAA, if the issuers are unable to successfully close future auctions 
and  their  credit  ratings  deteriorate,  the  Company  may  be  required  to  record  additional  unrealized  losses  in  other 
comprehensive income or an other-than-temporary impairment charge to earnings on these investments.

The  Company  recorded goodwill  of  approximately  $15.0  million  for  the  Propex  acquisition  in  February 2007.  
The Company recorded goodwill of approximately $1.1 million in connection with the First CLS, Inc. acquisition in 
April 2008. The decrease in goodwill in 2008 is related to foreign currency fluctuations. 

During the fourth quarters of 2007 and 2008, the Company completed the annual impairment test of goodwill 

and concluded that goodwill was not impaired.

9. INCOME TAXES ⎯ (CONTINUED) 

For  the  years  ended  December  31,  2007  and  2008,  a  valuation  allowance  has  been  established  for  certain 
deferred  tax  assets  due  to  the  uncertainty  of  realization.  The  Company’s  change  in  valuation  allowance  was  a 
decrease of approximately $274,000 for the year ended December 31, 2007 and an increase of approximately $3.0 
million  for  the  year  ended  December  31,  2008.  The  increase  for  the  year  ended  December  31,  2008  is  due  to  an 
increase in the valuation allowance required for the deferred tax assets for international loss carryforwards, capital 
loss carryforwards,  and unrealized losses on securities. The increase in the valuation allowance for the deferred tax 
asset  for  unrealized  losses  has  been  recorded  as  an  adjustment  to  other  comprehensive  income.  The  valuation 
allowance  for  the  year  ended  December  31,  2007  was  primarily  attributable  to  deferred  tax  assets  for  state  net 
operating loss carryforwards. 

  For the year ended December 31, 2008, the Company had income of approximately $52.7 million subject to 
applicable  U.S.  federal  and  state  income  tax  laws  and  a  loss  of  approximately  $8.0  million  subject  to  applicable 
international tax laws. 

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

income tax rate as follows (in thousands):

The  Company  paid  approximately  $858,000,  $1.1  million,  and  $13.4  million  in  income  taxes  for  the  years 

ended December 31, 2006, 2007 and 2008, respectively. 

The  Company  has  net  operating  loss  carryforwards  for  international  income  tax  purposes  of  approximately 

$10.1 million, which do not expire. 

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 $217,000 of unrecognized tax benefits, all of which would favorably affect the 
effective tax rate if recognized in future periods, and $52,000 of accrued penalties and $47,000 of accrued interest. 
The Company’s continuing practice is to recognize interest and penalties related to income tax matters in income tax 
expense.

Approximately  $142,000  and  $233,000  of  the  unrecognized  tax  benefit  as  of  December  31,  2008,  and  2007, 
respectively, would favorably affect the annual effective tax rate, if recognized in future periods. During 2008, the 
Company  recognized  approximately  $145,000  of  interest  and  $9,000  of  penalties,  and  had  total  accruals  of 
approximately $173,000 for interest and $34,000 for penalties as of December 31, 2008. During 2007, the Company 
recognized  approximately  $36,000  of  interest  and  $11,000  of  penalties,  and  had  total  accruals  of  approximately 
$74,000  for  interest  and  $57,000  for  penalties  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. 

The  Company’s  federal  and  state  income  tax  returns  for  tax  years  2005  through  2007  remain  open  to 
examination. The Company’s U.K. income tax returns for tax years 2002 through 2007 remain open to examination. 

10. 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 the leasehold interest in the office space located in London. The lease 
assignment was completed on December 19, 2007. As a result, CoStar U.K. was paid approximately $7.6 million, 
net of expenses, for the assignment of the lease. The expenses associated with the lease settlement included legal, 
moving and the disposal of assets. 

11. COMMITMENTS AND CONTINGENCIES 

The Company leases office facilities and office equipment under various noncancelable-operating leases. The 
leases contain various renewal options. Rent expense for the years ended December 31, 2006, 2007 and 2008 was

12.  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 Company’s subscription-based information/marketing services, consisting primarily of CoStar Property 
Professional®, CoStar Tenant®, CoStar COMPS Professional®, and FOCUSTM services, currently generate more than 
90%  of  the  Company’s  total  revenues.  CoStar  Property  Professional,  CoStar  Tenant,  and  CoStar  COMPS 
Professional are generally sold as a suite of similar services and comprise the Company’s primary service offering in 
the  U.S.  operating  segment.    FOCUS  is  the  Company’s  primary  service  offering  in  the  International  operating 
segment.  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.

Stock options to purchase approximately 86,900, 80,400 and 250,200 shares were outstanding as of December 
31,  2006,  2007  and  2008,  respectively,  but  were  not  included  in  the  computation  of  diluted  earnings  per  share 
because the exercise price of the stock options was greater than the average share price of the common shares and, 
therefore, the effect would have been anti-dilutive.

15. EMPLOYEE BENEFIT PLANS 

Stock Incentive Plans  

In June 1998, the Company’s Board of Directors adopted the 1998 Stock Incentive Plan (as amended, the “1998 
Plan”)  prior  to  consummation  of  the  Company’s  initial  public  offering.    In  April  2007,  the  Company’s  Board  of 
Directors  adopted  the  CoStar  Group,  Inc.  2007  Stock  Incentive  Plan  (as  amended,  the  “2007  Plan”),  subject  to 
stockholder approval, which was obtained on June 7, 2007.  All shares of common stock that were authorized for 
issuance  under  the  1998  Plan  that,  as  of  June  7,  2007,  remained  available  for  issuance  under  the  1998  Plan 
(excluding shares subject to outstanding awards) were rolled into the 2007 Plan and, as of that date, no shares of 
common stock were available 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,  directors  and  consultants  of  the  Company  and  its  subsidiaries.  Stock 
options  granted  under  the  2007  Plan  may  be  non-qualified  or  may  qualify  as  incentive  stock  options.  Except  in 
limited circumstances related to a merger or other acquisition, the exercise price for an option may not be less than 
the fair market value of the Company’s common stock on the date of grant.  The vesting period for each grant of 
options, restricted stock, restricted stock units and stock appreciation rights under the 2007 Plan is determined by the 
Board of Directors and is generally three to four years, subject to minimum vesting periods for restricted stock and 
restricted  stock  units  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 were subject as of such date to outstanding awards under the 1998 Plan), 
and (c) any shares of common stock subject to outstanding awards under the 1998 Plan as of June 7, 2007 that on or 
after such date cease for any reason to be subject to such awards (other than by reason of exercise or settlement of 
the  awards  to  the  extent  they  are  exercised  for  or  settled  in  vested  and  nonforfeitable  shares).  Unless  terminated 
sooner, the 2007 Plan will terminate in April 2017, but will continue to govern unexercised and unexpired awards 
issued  under  the  2007  Plan  prior  to  that  date.    Approximately  1.1  million  and  880,000  shares  were  available  for 
future grant under the 2007 Plan as of December 31, 2007 and 2008, respectively.

The aggregate intrinsic value is calculated as the difference between (i) the closing price of the common stock at 
December 31, 2006, 2007 and 2008 and (ii) the exercise prices of the underlying awards, multiplied by the shares 
underlying options as of December 31, 2006, 2007 and 2008, that had an exercise price less than the closing price on 
that date. Options to purchase 269,755, 288,757, and 198,434 shares were exercised for the years ended December 
31, 2006, 2007, and 2008, respectively.  The aggregate intrinsic value of options exercised, determined as of the date 
of option exercise, was $7.4 million, $7.5 million and $3.4 million, respectively. 

At  December  31,  2008,  there  was  $10.5  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 1.9 years. 

The weighted-average grant date fair value of each option granted during the years ended December 2006, 2007 

and 2008 was $33.45, $32.70 and $27.81, 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: 

Year Ended December 31, 
2007

Expected volatility ...........................................................................

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. 

The following table summarizes information regarding options outstanding at December 31, 2008:

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  2006, 2007 and 2008,  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,  2006,  2007  and  2008  were 
approximately $2.0 million, $2.3 million and $2.6 million, respectively. The Company paid administrative expenses 
in connection with the 401(k) plan of approximately $25,000, $22,000 and $28,000 for the years ended December 
31, 2006, 2007 and 2008, 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,  2006,  2007  and  2008  were  approximately 
$193,000, $281,000 and $265,000, 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  second  Saturday  before  each  of  the  Company’s  regular  pay  dates  and  ends  on  each  of  the 
Company’s  regular  pay  dates.    There  were  86,308  and  78,840  shares  available  for  purchase  under  the  plan  as  of 
December 31, 2007 and 2008, respectively and approximately 9,000 and 7,400 shares of the Company’s common 
stock were purchased during 2007 and 2008, respectively.
