Strategy

Since our founding, in 1987, CoStar’sour 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., February 2007 acquisition of Property Investment Exchange Limited, and July 2009 acquisition of Property and Portfolio Research, Inc. (“PPR”) and its wholly owned U.K. subsidiary, Property and Portfolio Research Ltd. (“PPR UK”), weWe have extended our offering of comprehensive commercial real estate information to include London and other parts of the U.K. and parts of France.France, through acquisitions and internal growth and development. Information about CoStar’s revenues from, and long-lived assets and total assets located in, foreign countries is included in Notes 2 and 1112 of the Notes to our consolidated financial statements.

Risk Factors" and “Item 7A. Quantitative and Qualitative Disclosures about Market Risk.”

We deliver our content to our U.S. customers primarily via an integrated suite of online service offerings that includes information about space available for lease, tenant information, comparable sales information, tenant information, information about properties for sale, internet marketing services, propertyanalytical capabilities, information for clients’ websites, information about industry professionals and their business relationships, analytic information, data integration and industry news. LoopNet, our subsidiary, operates an online marketplace that enables property owners, landlords, and commercial real estate agents working on their behalf to list properties for sale or for lease and to submit detailed information about property listings. Commercial real estate agents, buyers and tenants also use LoopNet's online marketplace to search for available property listings that meet their criteria. We also provide market research and analysis for commercial real estate investors and lenders via our PPRProperty and Portfolio Research (“PPR”) service offerings, and portfolio and debt management and reporting capabilities through our Resolve Technology Inc. (“Resolve Technology”)service offerings; and real estate and lease management solutions, including lease administration and abstraction services, through our Virtual Premise service offerings. We have created and are continually improving aour standardized information, analytics and marketing platform where th emembers of the commercial real estate industry and related businessesbusiness community can continuously interact and easily facilitate transactions due to the efficient exchange ofby efficiently exchanging accurate information we supply.and standardized commercial real estate information.

We have a number of assets that provide a unique foundation for ourOur standardized platform includingincludes 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, marketinganalytics and analyticmarketing services; a large team of analysts and economistseconomists; and a large base of clients. Our database has been developed and enhanced for more than 2326 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 52approximately 80 proprietary databases.

We intend to continue to grow our standardized platform of commercial real estate information, marketing and analytic services.  In 2004, we began research for a 21-market U.S. expansion effort.  By the end of the first quarter of 2006, we 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 e ffort 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 websites, www.CoStar.com and www.showcase.com.

During the second half of 2009, as part of our strategy for providing subscribers with tools for conducting primary research and analysis on commercial real estate, we expanded subscribers’ capabilities to use our database of research-verified commercial property information to conduct in-depth analysis and generate online reports of trends in sales and leasing activity.  Furthermore, in July 2009, we added analytic and market forecasting services to our platform of research and marketing services with our acquisition of PPR, and in October 2009 we acquired Resolve Technology’s business intelligence and portfolio management software used by institutional real estate investment companies.

We also intend to continue to expand the coverage of our service offerings within our International segment.  In December 2006, our 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.  Our July 2009 acquisition of PPR and PPR UK also expanded the market research capabilities of our U.K. operations.  Further information about CoStar’s acquisitions is included in Note 3 to our consolidated financial statements.

  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.  In 2007, we introduced the “CoStar Group” as the brand encompassing our worldwide operations.

Following our acquisitions of PPR and Resolve Technology in 2009, we began integrating their respective product and service offerings with our own, including the services we have successfully integrated following prior acquisitions.  We believe that our recent U.S. and International expansion and integration efforts have created a platform for long-term growth.

Our subscription-based information services consistingconsist primarily of CoStar Property Professional,SuiteTM and FOCUSTM services. CoStar Tenant, CoStar COMPS Professional and FOCUS services, currently generate more than 94% of our total revenues.

Our subscription-based services consist primarily of similar services offered over the Internet to commercial real estate industry and related professionals. Our services are typically distributed to our clients under subscription-based license agreements that renew automatically, a majority of our contracts for our subscription-based information services typicallywhich have a minimum term of one year and renew automatically.year. Upon renewal, many of the subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations. To encourage clients to use our services regularly, we generally charge a fixed monthly amount for our subscription-based information services rather than charging fees based on actual system usage. Contract rates are generally based on the number of sites, number of users, organization size, the client’sclient'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.

Expansion and Growth

Acquisitions

We have continually expanded the geographical coverage of our existing information services and developed new information, analytics and marketing services. In addition to internal growth, we have grown our business through strategic acquisitions.

Historically, our expansion includes the acquisitions of Chicago ReSource in Chicago in 1996 and New Market Systems 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 In January 1999, we expanded further into the Midwest and Florida by acquiring LeaseTrend and into Atlanta and Dallas/Fort Worth by acquiring Jamison Research. In February 2000, we acquired COMPS.COM, a San Diego-based provider of commercial real estate information. In November 2000, we acquired First Image Technologies, 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, and in June 2004, we extended our coverage of the U.K. through the acquisition of Scottish Property Network. In September 2004, we strengthened our position in Denver, Colorado through the acquisition of substantially all of the assets of RealComp, a local comparable sales information provider.

In January 2005, we acquired National Research Bureau, a Connecticut-based 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 (doing business as the Dorey Companies and DoreyPRO), an Atlanta-based provider of local commercial real estate information. In July 2009, we acquired Massachusetts-based PPR, a provider of real estate analysis, market forecasts and credit risk analytics to the commercial real estate industry, and its wholly owned U.K. subsidiary Property and Portfolio Research Ltd., and in October 2009, we acquired Massachusetts-based Resolve Technology, a provider of business intelligence and portfolio management software serving the institutional real estate investment industry. In October 2011, we acquired Virtual Premise, a Software as a Service, or on-demand software provider of real estate and lease management solutions located in Atlanta, Georgia. More recently, on April 30, 2012, we completed the acquisition of LoopNet, an online marketplace that enables property owners, landlords, and commercial real estate agents working on their behalf to list properties for sale or for lease and to submit detailed information about property listings.

Development

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

In October 2013, we introduced technology enhancements to CoStar Suite, our platform of service offerings consisting of CoStar Property Professional, CoStar COMPS Professionaland CoStar Tenant. The enhancements improve Costar Suite's user interface, search functionality and analytic capabilities. The newly introduced CoStar MultifamilyTM information search allows access to our extensive multifamily property database. In addition, we introduced CoStar Lease AnalysisTM, an integrated workflow tool that provides users a simple way to produce understandable cash flows for any proposed or existing lease. We expect to continue software development on our new Lease Analysis workflow tool throughout 2014.

Further, in October 2013, we released CoStarGo® 2.0, the next generation of our mobile application, which was launched in the U.S. on August 15, 2011 and introduced in the U.K. on November 5, 2012. CoStarGo is our iPad application that integrates and provides CoStar Suite subscribers mobile access to our comprehensive property, tenant and comparable sales information. CoStarGo 2.0 adds powerful analytic capabilities to our comprehensive mobile solution.

We have introduced enhancements to our flagship marketing platform, LoopNet.com. For example, we added a broker advertising service that allows brokers to purchase advertisements based on geographic and property type criteria. Additionally, we introduced ProVideo, a service that enables owners and brokers to enhance their listings with high quality videos of interior spaces, amenities and exterior features. We expect to continue software development to improve the LoopNet marketing platform in 2014.

We continue to integrate, develop and cross-sell the services offered by the companies we acquired most recently, including LoopNet, Virtual Premise, Resolve Technology and PPR. In some cases, when integrating and coordinating our services and assessing industry needs, we may decide, or may have previously decided, to combine, shift focus from, de-emphasize, phase out, or eliminate a service that overlaps or is redundant with other services we offer.

International Expansion and Development

We continue to integrate our international operations more fully with those in the U.S. As part of our integration efforts, in 2007 we introduced “CoStar Group” as the brand encompassing our international operations, and in early 2010 we launched Showcase, our internet marketing service that provides commercial real estate professionals high quality internet lead generation, in the U.K. In addition, we intend to continue to upgrade the platform of services and expand the coverage of our service offerings within our International segment. To further develop those initiatives, we introduced CoStar Suite in the U.K. during the fourth quarter of 2012 and no longer offered FOCUS to new clients beginning in 2013. CoStar Suite is sold as a consistent international platform of service offerings consisting of CoStar Property Professional, CoStar COMPS Professionaland CoStar Tenant and through the Company's mobile application, CoStarGo. CoStarGo 2.0 was released in the U.K. in October 2013 simultaneous with the release in the U.S. Additionally, we have upgraded our back-end research operations, fulfillment and Customer Relationship Management (“CRM”) systems to support these new U.K. services. In order to implement these services in the U.K., we incurred increased development costs through 2012; however, development costs incurred by the International segment decreased in 2013. The International operating segment continues to experience improved financial performance and most recently, during the three months ended December 31, 2013, International EBITDA increased to a positive amount as a result of increased revenue and decreased operating expenses.

In 2014, we expect to expand further internationally by offering our services in Toronto, Canada. We believe that our integration efforts and continued investments in our services, including expansion of our existing service offerings internationally, have created a platform for long-term revenue growth. We expect these investments to result in further penetration of our international subscription-based information services and the successful cross-selling of our services to customers in existing markets.

Industry Overview

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

A large number of parties involved in the commercial real estate and related business community make use of the services we provide in order to obtain information they need to conduct their businesses, including:

Sales and leasing brokersGovernment agencies
Property ownersMortgage-backed security issuers
Property managersAppraisers
Design and construction professionalsPension fund managers
Real estate developersReporters
Real estate investment trust managersTenant vendors
Investment bankersBuilding services vendors
Commercial bankersCommunications providers
Mortgage bankersInsurance companies’ managers
Mortgage brokersInstitutional advisors
RetailersInvestors and asset managers

The commercial real estate and related business community generally has operated in an inefficient marketplace because of the fragmented approach to gathering and exchanging information within the marketplace. Various organizations, including hundreds of brokerage firms, directory publishers and local research companies, collect data on specific markets and develop software to analyze the information they have independently gathered. This highly fragmented methodology has resulted in duplication of effort in the collection and analysis of information, excessive internal cost and the creation of non-standardized data containing varying degrees of accuracy and comprehensiveness, resulting in a formidable information gap.

The creation of a standardized information platform for commercial real estate requires an infrastructure including a standardized database, accurate and comprehensive research capabilities, experienced analysts, easy to use technology and intensive participant interaction. By combining our extensive database, approximately 9571,123 researchers and outside contractors, our experienced team of analysts and economists, technological expertise and broad customer base, we believe that we have created such a platform.

CoStar’s Comprehensive Database

CoStar has spent more than 2326 years building and acquiring a database of commercial real estate information, which includes information on leasing, sales, comparable sales, tenants, and demand statistics, as well as digital images.

As of January 31, 2011,2014, our database of real estate information covered the U.S., London, England and other parts of the U.K., and parts of France, and contained:

contained information about:

Approximately 1.5 million sale and lease listings;
Approximately 4.04.3 million total properties;
Approximately 11.18.6 billion square feet of sale and lease listings;
Approximately 8.95.7 million tenants;
Approximately 1.82.1 million sales transactions valued in the aggregate at approximately $3.7 trillion;$5.0 trillion; and
Approximately 11.215.3 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:

LocationMortgage and deed information
Site and zoning informationFor-sale information
Building characteristicsIncome and expense histories
Space availabilityTenant names
Tax assessmentsLease expirations
OwnershipContact information
Sales and lease comparablesHistorical trends
Space requirementsDemographic information

CoStar Research

We have developed a sophisticated data collection organization utilizing a multi-faceted research process. In 2010,2013, 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 31, 2011,2014, we had approximately 9571,123 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 and 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 t hatthat allow them to gather useful information. Because of the importance commercial real estate professionals place on our data and our prominent position in the industry, many of these professionals routinely take the initiative and proactively report available space and transactions to our researchers.

CoStar has an extensive field research effort that includes physical inspection of properties in order to research new markets, find additional property inventory, photograph properties and verify existing information.

CoStar's field research effort also includes creating high quality videos of interior spaces, amenities and exterior features of properties. CoStar utilizes 144115 high-tech, field research vehicles in 41 statesacross the U.S., Canada and the U.K. OfA significant majority of these vehicles 98 are custom-designedcustomized 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, marketinganalytics and analyticmarketing 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 lic enselicense fees plus additional fees based upon our usage.


8



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

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

Finally, one of the most important and effective quality control measures we rely on is feedback provided by the commercial real estate professionals using our data every day.

Sales and Marketing

As of January 31, 2011,2014, we had 262559 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 2330 field sales offices throughout the U.S. and in offices located in London, England; Manchester, England; Glasgow, ScotlandScotland; Paris, France and Paris, France.Toronto, Canada. Our inside sales team isteams are located in our downtown Washington, DC. office. This team prospectsDC; San Francisco, California; and Glendora, California offices. These teams prospect for new clients and performsperform service demonstrations exclusively by telephone and over the internetInternet to support the direct sales force. A portion of the inside sales teams are also responsible for selling some of our services.

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 information services rather than fees based on actual system usage. Contract rates for subscription-based services are generally based on the number of sites, number of users, organization size, the client’s business focus, geography and the 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.

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; Company-sponsored events; print advertising in trade magazines and other business publications; client referrals; CoStar AdvisorTM, LoopNewsTMand CoStar Advisor™, the Company’s newsletter, which isother company newsletters distributed via email to our clients and prospects. We currently offer dozens of webinars each year aimed at helping customers learn more about the commercial real estate industry and how to use our services. The webinars are available both as live presentations and as on-demand programs hosted on our website. On a monthly basis, we issue the CoStar Commercial Repeat Sales Index (CCRSI)("CCRSI"), a comprehensive set of benchmarks that investors and other market participants can use to better understand commercial real estate price movements. The Index is produced using our underlying data and is publicly distributed by CoStar through the news media and made available online at www.costar.com/ccrsi.

Web-based marketing and direct marketing are the most cost-effective means for us to find prospective clients. Our web-based marketing efforts include search engine optimization, paid advertising with major search engines and display advertising on commercial real estate news sitesand business websites and mobile applications, 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, including industry-leading events for commercial real estate brokers, owner/investors and retail and financial services institutions, and attend and/or exhibit at industry trade shows and conferences to reinforce our relationships with our core user groups.

Our sales and marketing efforts have focused and will continue to focus on cross-selling and marketing our services. For example, after the acquisition of LoopNet, we launched a sales and marketing campaign to cross-sell CoStar's information services to LoopNet customers and cross-sell LoopNet's marketing services to CoStar customers. We recently implemented an automatic cross-selling initiative within the LoopNet marketplace. As searchers view properties within the LoopNet marketplace, a message may appear indicating that there are additional listings available within CoStar Suite with the same search criteria that they are not able to access under their current subscription. The message provides contact information, so that the customer can reach their customer service or sales representative and review the most appropriate service for their needs. Our goal is to upsell clients to the services that best meet their needs and to create further cross-selling revenue synergies. In addition, we have added a comparison feature to CoStarGo, which allows our sales force to demonstrate how many more properties a prospect could see with respect to a particular search area if that prospect were using CoStar rather than the prospect’s current subscription with LoopNet.

Competition

The market for information, marketinganalytics and analyticmarketing services generally is competitive and rapidly changing. In the commercial real estate industry, the principal competitive factors for commercial real estate information, marketinganalytics and analyticmarketing services and providers are:

13

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

publishers and distributors of information, marketinganalytics and analyticmarketing services, including regional providers and national print publications, such as Black’s Guide,Xceligent, eProperty Data, CBRE Economic Advisors, Marshall & Swift, Yale Robbins, Inc., Reis, Inc., Real Capital Analytics Inc. and The Smith Guide, Inc.;
Guide;

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

real estate portfolio management software solutions, such as Cougar Software, Yardi Systems, MRI Software, Argus SoftwareAltus and Intuit Inc.;
Intuit;

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

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

public record providers.

As the commercial real estate information, marketinganalytics and analyticmarketing services marketplace develops, additional competitors (including companies which could have greater access to data, financial, product development, technical, analytic or marketing resources than we do) may enter the market and competition may intensify. A company like Bloomberg L.P. has the resources and has previously announced an intention to move into the commercial real estate information business. Further, a company like Google, which has a far-reaching web presence and substantial data aggregation capabilities, could easily enter the commercial real estate marketing arena. While we believe that we have successfully differentiated ourselves from existing competitors, current or future competitors could materially harm our business.

Risk Factors

Risks Related to our Business

Our revenues and financial position will be adversely affected if we are not able to attract and retain clients. Our success and revenues depend on attracting and retaining subscribers to our information, analytics and marketing services. Our subscription-based information, analytics and 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; the business failure of a current client or clients; a decision that customers have no need for our services; a decision to use alternative services; customers’ and potential customers’ pricing and budgetary constraints; consolidation in the real estate and/or financial services industries; data quality; technical problems; or competitive pressures. If clients cancel services or decide not to renew their subscription agreements, and we do not sell new services to our existing clients or attract new clients, then our renewal rate and revenues may decline.
A downturn or consolidation in the commercial real estate industry may decrease customer demand for our services. A reversal of recent improvements in the commercial real estate industry’s leasing activity and absorption rates or a renewed downturn in the commercial real estate market may affect our ability to generate revenues and may lead to more cancellations by our current or future customers, either of which could cause our revenues or our revenue growth rate to decline and reduce our profitability. A depressed commercial real estate market has a negative impact on our core customer base, which could decrease demand for our information, marketinganalytics and analyticmarketing 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, marketinganalytics and analyticmarketing services by our customers, reduce the number of our existing clients, reduce the size of our target market or increase our clients’ bargaining power, all of which could cause our revenues to decline and reduce our profitability.

Negative general economic conditions could increase our expenses and reduce our revenues. Our business and the commercial real estate industry are particularly affected by negative trends in the general economy. The success of our business depends on a number of factors relating to general global, national, regional and local economic conditions, including perceived and actual economic conditions, recessions, inflation, deflation, exchange rates, interest rates, taxation policies, availability of credit, employment levels, and wage and salary levels. Negative general economic conditions could adversely affect our business by reducing our revenues and profitability. If we experience greater cancellations or reductions of services and failures to timely pay, and we do n otnot acquire new clients or sell new services to our existing clients, our revenues may decline and our financial position would be adversely affected.  Adverse national and global economic events, as well as any significant terrorist attack, are likely to have a dampening effect on the economy in general, which could negatively affect our financial performance and our stock price. Market disruptions may also contribute to extreme price and volume fluctuations in the stock market that may affect our stock price for reasons unrelated to our operating performance.  In addition, a significant
16

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.

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


18



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 2014, we plan to continue to increase the depth of our coverage in the U.S. and U.K., and we expect to expand into additional geographies including Toronto, Canada.  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.

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. We may incur costs in the preliminary stages of an acquisition, but may ultimately be unable or unwilling to consummate the proposed transaction for various reasons. In addition, acquisitions involve numerous risks, including the ability to realize or capitalize on synergy created through combinations; managing the integration of personnel and products; potential increases in operating costs; managing geographically remote operations, such as SPN in Scotland, Grecam S.A.S. in France, CoStar U.K. Limited, Propex and Property and Portfolio Research Ltd. in the U.K.;operations; the diversion of management’s attention from other business concerns;concerns and potential disruptions in ongoing operations during integration; the inherent risks in entering markets and sectors in which we have either limited or no direct experience; and the potential loss of key employees, clients or clientsvendors and other business partners of the acquired companies. We may not successfully integrate acquired businesses or assets and may not achieve anticipated benefits of an acquisition, including expected synergy.synergies. Acquisitions could result in dilutive issuances of equity securities, the incurrence of debt, one-time write-offs of goodwill and substantial amortization expenses of other intangible assets. We may be unable to obtain financing on favorable terms, or at all, if necessary to finance future acquisitions making it impossible or more costly to acqui reacquire complementary businesses. If we are able to obtain financing, the terms may be onerous and restrict our operations. Further, certain acquisitions may be subject to regulatory approval, which can be time consuming and costly to obtain, and the terms of such regulatory approvals may impose limitations on our ongoing operations or require us to divest assets or lines of business.

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

We may not be able to successfully introduce new or upgraded information, analytics and marketing services or combine or shift focus from services with less demand, which could decrease our revenues and our profitability. Our future business and financial success will depend on our ability to continue to anticipate the needs of, and to introduce new and upgraded services into the marketplace. To be successful, we must adapt to changes in the industry, as well as rapid technological changes by continually enhancing our information, analytics and marketing services. Developing new services and upgrades to services, as well as integrating and coordinating current services, imposes heavy burdens on our systems department, management and researchers. The processes are costly, and our efforts to develop, integrate and enhance our services may not be successful. As we continue to combine our operations with those that we have acquired, we must continue to assess the purposes for which various services may be used alone or together, and how we can best address those uses through stand-alone services or combinations or coordinating applications thereof. In addition, successfully launching and selling a new or upgraded service puts pressure on our sales and marketing resources. If we are unable to hire qualified persons for,develop new or retainupgraded services or decide to combine, shift focus from, or phase out a service that overlaps or is redundant with other services we offer, then our customers may choose a competitive service over ours and continue to develop, our sales force, or if our sales force is unproductive, our revenues could be adversely affected. In order to support revenues and future revenue growth, we need to continue to develop, train and retain our sales force. Our ability to build and develop a strong sales force may be affected by a number of factors, including: our ability to attract, integrate and motivate sales personnel; our ability to effectively train our sales force; the ability of our sales force to sell an increased number 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 ret aining 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 expensesprofitability may be reduced. In addition, if we incur significant costs in developing new or upgraded services or combining and coordinating existing services, are not successful in marketing and selling these new services or upgrades, or our customers fail to accept these new or combined and coordinating services, it could increase.have a material adverse effect on our results of operations by decreasing our revenues and reducing our profitability.


19



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 have decreased 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 could decline. Increased competition could result in lower revenues and higher expenses, which would reduce our profitability.

Our focus on internal and external investments may place downward pressure on our operating margins. Over the past few years, we have increased the rate of investments in our business, including internal investments in product development and sales and marketing, to expand the breadth and depth of services we provide to our customers. Our investment strategy is intended to increase our revenue growth in the future as activity in the commercial real estate industry shows signs of economic recovery. Our operating margins may experience downward pressure in the short term as a result of investments. Furthermore, if the industry fails to stabilize or deteriorates further in 2014 and beyond, our investments may not have their intended effect. For instance, our external investments may lose value and we may incur impairment charges with respect to such investments. Such impairment charges may negatively impact our profitability. If we are unable to successfully execute our investment strategy or if we fail to adequately anticipate and address potential problems, we may experience decreases in our revenues and operating margins.
17


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 changes in these standards may adversely impact the viability or value 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, analytics and marketing services and could reduce our profitability.

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

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


20



If we fail to protect confidential information against security breaches, or if customers or potential customers are reluctant to use our services because of privacy concerns, we might face additional costs and could lose customers or potential customers. We collect, use and disclose personally identifiable information, including among other things names, addresses, phone numbers, and email addresses. In certain circumstances, we also collect and use credit card information. Our policies concerning the collection, use and disclosure of personally identifiable information are described on our websites. While we believe that our policies are appropriate and that we are in compliance with our policies, we could be subject to legal claims, government action or harm to our reputation if our practices fail, or are seen as failing, to comply with our policies or with applicable laws concerning personally identifiable information.

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

Concern of prospective customers regarding our use of the personal information collected on our websites could keep prospective customers from subscribing to our services. Industry-wide incidents or incidents with respect to our websites, including misappropriation of third-party information, security breaches, or changes in industry standards, regulations or laws, could deter people from using the Internet or our websites to conduct transactions that involve the transmission of confidential information, which could harm our business. Under various state laws, if there is a breach of our computer systems and we know or suspect that unencrypted personal customer data has been stolen, we are required to inform any customers whose data was stolen, which could result in significant costs and harm our reputation and business.

In addition, certain state laws require businesses that maintain personal information in electronic databases to implement reasonable measures to keep that information secure. Various states have enacted different and sometimes contradictory requirements for protecting personal information collected and maintained electronically. Compliance with numerous and contradictory requirements of the different states is particularly difficult for an online business such as ours which collects personal information from customers in multiple jurisdictions.

We may face adverse publicity and loss of consumer confidence if we are not able to comply with laws requiring us to take adequate measures to assure the confidentiality of the personally identifiable information that our customers had given to us. This could result in a loss of customers and revenue that could jeopardize our success. Even if we are in full compliance with all relevant laws and regulations, we may face liability or disruption of business if we do not comply in every instance or if the security of the customer data that we collect is compromised, regardless of whether our practices comply or not. If we were required to pay any significant amount of money in satisfaction of claims under these laws, or if we were forced to suspend operations for any length of time due to our inability to comply fully with any such laws, our business, operating results and financial condition could be adversely affected.

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. 


21



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

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

These types of events or indicators and the resulting impairment analysis could result in goodwill impairment charges in the future, which would reduce our profitability. Impairment charges could negatively affect our financial results in the periods of such charges, which may reduce our profitability. As of December 31, 2013, we had $718.6 million of goodwill, $692.6 million in our U.S. segment and $26.0 million in our International segment.  

As a result of the consolidation of certain of our facilities, we may incur additional costs.  We have taken, and may continue to take, actions that may increase our cost structure in the short-term but are intended to reduce certain portions of our long-term cost structure, such as consolidation of office space. As a result of consolidation of office space, we may reduce our long-term occupancy costs, but incur restructuring charges. If our long-term cost reduction efforts are ineffective or our estimates of cost savings are inaccurate, our profitability could be negatively impacted. Expected savings from relocating facilities can be highly variable and uncertain. Further, we may not be successful in achieving the operating efficiencies or operating cost reductions expected from these efforts in the amounts or at the times we anticipate.

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

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

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

22



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

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

Fluctuating foreign currencies may negatively impact our business, results of operations and financial positionposition. . Due to our acquisitions of CoStar U.K. Limited (formerly FOCUS Information Limited), SPN, Grecam S.A.S., Propex, and Property and Portfolio Research Ltd., a portion of our business is denominated in the British Pound and Euro andEuro. If we expand into Canada as expected, a portion of our business will be denominated in Canadian dollars. As a result, fluctuations in foreign currencies may have an impact on our business, results of operations and financial position. Foreign currency exchange rates have fluctuated and may continue to fluctuate. Significant foreign currency exchange rate fluctuations may negatively impact our international revenue, which in turn affects our consolidated revenue. Currencies may be affected by internal factors, gen eralgeneral 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 Eurorespective, local currency may decrease the value of our foreign assets, as well as decrease our revenues and earnings from our foreign subsidiaries, which would reduce our profitability and adversely affect our financial position.

Our expansion into the commercial real estate analytics sector may not be successful or may not result in increased revenues, which may negatively impact our business, results of operations and financial position. Expanding into the commercial real estate market research and forecasting sector has imposed and may continue to impose additional burdens on our research, systems development, sales, marketing and general management resources. During 2014, we expect to continue to expand our presence in the commercial real estate analytics sector. If we are unable to manage this expansion effectively or if our costs for this effort exceed our expectations, our financial position could be adversely affected.  In addition, if we incur additional costs to expand our analytics services and we are not successful in marketing or selling these expanded 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.

Our indebtedness could adversely affect us, including by decreasing our business flexibility and increasing our costs.On February 16, 2012, we entered into a Credit Agreement by and among CoStar, as borrower, CoStar Realty Information, Inc., as co-borrower, the lenders from time to time party thereto and J.P. Morgan Bank, as administrative agent. The Credit Agreement provides for a $175.0 million term loan facility and a $50.0 million revolving credit facility, each with a term of five years. On April 30, 2012, we used the proceeds of the $175.0 million term loan facility to fund a portion of the merger consideration and transaction costs for the LoopNet acquisition. The Credit Agreement contains customary restrictive covenants imposing operating and financial restrictions on us, including restrictions that may limit our ability to engage in acts that we believe may be in our long-term best interests. These covenants restrict our ability and the ability of our subsidiaries (i) to incur additional indebtedness, (ii) to create, incur, assume or permit to exist any liens, (iii) to enter into mergers, consolidations or similar transactions, (iv) to make investments and acquisitions, (v) to make certain dispositions of assets, (vi) to make dividends, distributions and prepayments of certain indebtedness, and (vii) to enter into certain transactions with affiliates.
The operating restrictions and financial covenants in the Credit Agreement and any future financing agreements may limit our ability to finance future operations or capital needs, to engage in other business activities or to respond to changes in market conditions. Our ability to comply with any financial covenants could be materially affected by events beyond our control. If we fail to comply with these covenants, we may need to seek waivers or amendments of such covenants, seek alternative or additional sources of financing or reduce our expenditures. We may be unable to obtain such waivers, amendments or alternative or additional financing on a timely basis or at all, or on favorable terms.

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

Negative conditions in the global credit markets may affect the liquidity of a portion of our long-term investments.  Currently, our long-term investments include mostly AAA ratedAAA-rated auction rate securities (“ARS”), which are primarily student loan securities supported by guarantees from the Federal Family Education Loan Program (“FFELP”) of the U.S. Department of Education. Continuing negative conditions in the global credit markets have prevented some investors from liquidating their holdings of auction rate securities because the amount of securities submitted for sale has exceeded the amount of purchase orders for such securities. As of December 31, 2010,2013, we held $32.2$24.3 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.

18

Our ARS investments are not currently actively trading and therefore do not currently have a readily determinable market value. Accordingly, theThe 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, 2010.2013. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of cash flows, liquidity risk premiums, expected holding periods and default risk of the ARS. We update the discounted cash flow model on a quarterly basis to reflect any changes in the assumptions used in the model and settlements of ARS investments that occurred during the period. Based on this assessment of fair value, as of December 31, 2010,2013, we determined there was a decline in the fair value of our ARS investments of approximately $3.0 million.$1.5 million. The decline was deemed to be a temporary impair mentimpairment and was recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. If the issuers of these ARS are unable to successfully close future auctions and/or their credit ratings deteriorate, we may be required to record additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments, which would reduce our profitability and adversely affect our financial position.

We have not made any material changes in the accounting methodology used to determine the fair value of the ARS. We do not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used to calculate the fair value of the ARS as of December 31, 2010.2013. However, if changes in these assumptions occur, and, should those changes be significant, we may be required to record additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments.

U.S. political, credit and financial market conditions may negatively impact or impair the value of our current portfolio of cash, cash equivalents and investments, including U.S. Treasury securities and U.S.-backed investments, as well as our access to credit.Our cash, cash equivalents and investments are held in a variety of common financial instruments, including U.S. treasury securities. Deterioration in the U.S. credit and financial markets may result in losses or deterioration in the fair value of our cash, cash equivalents, or investments.  On August 5, 2011, Standard & Poor’s lowered its long term sovereign credit rating on the U.S. from AAA to AA+. This downgrade, and any future downgrades of the U.S. credit rating, could impact the stability of future U.S. treasury auctions, affect the trading market for U.S. government securities, result in increased interest rates and impair access to credit. These factors could negatively impact the liquidity or valuation of our current portfolio of cash, cash equivalents, and investments, which may affect our ability to fund future obligations. Further, these factors may result in an increase in interest rates and borrowing costs and make it more difficult to obtain credit on acceptable terms, which may affect our ability to fund future obligations and increase the costs of obtaining financing for future obligations.

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, analytics and marketing services, lower revenues and increased costs. Our currentbusiness 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 future geographic expansion plansthe 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, analytics and marketing services. If we experience technical problems in distributing our services, we could experience reduced demand for our information, analytics and marketing services. In addition, the software, internal applications and systems underlying our services are complex and may not resultbe 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, analytics and marketing services, which could reduce the demand for our services, lower our revenues and increase our costs.

Temporary or permanent outages of our computers, software or telecommunications equipment could lead to reduced demand for our information, analytics and marketing services, lower revenues and increased costs. Our operations depend on our ability to protect our databases, 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, analytics and marketing services to clients, we could experience reduced demand for our information, analytics and marketing services, lower revenues and increased costs.

Our operating results and revenues are subject to fluctuations and our quarterly financial results may be subject to seasonality and market cyclicality, each of which could cause our stock price to be negatively affected. The commercial real estate market may be influenced by general economic conditions, economic cycles, annual seasonality factors and many other factors, which in increased revenues, whichturn may negatively impact our business, resultsfinancial results. The market is large and fragmented. The different sectors of operationsthe industry, such as office, industrial, retail, multi-family, and financial position. Expanding into new marketsothers, are influenced differently by different factors, and investing resources towards increasinghave historically moved through economic cycles with different timing. As such, it is difficult to estimate the depthpotential impact of our coverage within existing markets imposes additional burdenseconomic cycles and conditions or seasonality from year-to-year on our research, systems development, sales, marketingoverall operating results. In addition, our results may be impacted by seasonality. The timing of widely observed holidays and general managerial resources.  During 2011, we plan to continue to increasevacation periods, particularly slow downs during the depthend-of-year holiday period, and availability of real estate agents and related service providers during these periods, could significantly affect our coverage in the U.S., U.K and France, and we may expand into additional geographies.quarterly operating results during that period. If we are unable to manage our expansion efforts effectively, if our expansion efforts take longer than plannedadequately respond to economic, seasonal or if our costs for these efforts exceed our expectations, our financial position could be advers ely 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 increasingcyclical conditions, our revenues, adversely affecting our profitability.

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 t o reduce our exposure to such liability, which may require us to expend substantial resources and limit the attractiveness of our information, marketing and analytic services to users.

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

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
19

units under Financial Accounting Standards Board (“FASB”) authoritative guidance for consideration of potential impairment of goodwill. We assess the impairment of long-lived assets, identifiable intangibles and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. 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 results in the periods of such charges, which may reduce our profitability. As of December 31, 2010, we had $79.6 million of goodwill, $55.3 million in our U.S. segment and $24.3 million in our International segment.

In addition, changes in accounting policies or practices may affect our level of net income. Fluctuations in our financial results, revenues and expenses may cause the market price of our common stock to decline.

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

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


26



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

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

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, the stock market in general, and the shares of internet-related and other technology companies in particu lar,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.

We may not be able to successfully introduce new or upgraded information, marketing and analytic 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 and analytic 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 market ing resources. If we are unable to develop new or upgraded services, then our customers may choose a competitive service over ours and our revenues may decline and our profitability may be reduced. In addition, if we incur significant costs in developing new or upgraded services, are not successful in marketing and selling these new services or upgrades, or our customers fail to accept these new services, it could have a material adverse effect on our results of operations by decreasing our revenues and reducing our profitability.

Our expansion into the commercial real estate analytics sector may not be successful or may not result in increased revenues, which may negatively impact our business, results of operations and financial position.  Expanding into the commercial real estate market research and forecasting arena imposes additional burdens on our research, systems development, sales, marketing and general management resources.  During 2011, we expect to continue to expand our presence in the commercial real estate analytics sector.  If we are unable to manage this expansion effectively or if our costs for this effort exceed our expectations, our financial position could be
20

adversely affected.  In addition, if we incur additional costs to expand our analytics services and we are not successful in marketing or selling these expanded 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.

As a result of consolidation of facilities, we may incur additional costs.  We have taken, and may continue to take, actions that may increase our cost structure in the short-term but are intended to reduce certain portions of our long-term cost structure, such as consolidation of office space. As a result of consolidation of office space, we may reduce our long-term occupancy costs, but incur restructuring charges.  If our long-term cost reduction efforts are ineffective or our estimates of cost savings are inaccurate, our profitability could be negatively impacted.  Expected savings from relocating facilities can be highly variable and uncertain.  For instance, we may not meet the requirements necessary to receive the full property tax a batement provided by the District of Columbia as incentive for us to relocate our headquarters to downtown Washington, DC and may incur greater property taxes than anticipated in connection with the move to our new headquarters.    Further, we may not be successful in achieving the operating efficiencies or operating cost reductions expected from these efforts in the amounts or at the times we anticipate.

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 and analytic services and could reduce 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 and analytic 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 and analytic services. If we experience technical problems in distributing our services, we co uld experience reduced demand for our information, marketing and analytic 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 and analytic 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 and analytic services. Our success depends on our clients’ confidence in the comprehensiveness, accuracy and reliability of the data and analysis we provide. The task of establishing and maintaining accurate and reliable data and analysis is challenging. If our data, including the data we obtain from third parties, or analysis is not current, accurate, comprehensive or reliable, we could experience reduced demand for our services or legal claims by our customers, which could result in lower revenues and higher expenses. Our U.S. researchers use integrated internal research processes to update our database.  Any inef ficiencies, 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.

21

Temporary or permanent outages of our computers, software or telecommunications equipment could lead to reduced demand for our information, marketing and analytic 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 and analytic services to clients, we could experience reduced deman d for our information, marketing and analytic 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 net income, which reductions may be independent of changes in our operations. These reductions in reported net income could cause our stock price to decline.  For example, in 2006, we adopted authoritative guidance for stock compensation, which required us to expense the value of granted stock options.

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 o ur business of the loss of the services of Mr. Florance or other key officers or employees.

Item 7.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 ¾- Cautionary Statement Concerning Forward-Looking Statements” and ¾“- 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.statements, whether as a result of new information, future events or otherwise. The following discussion should be read in conjunction with our Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the Securities and Exchange Commission and the consolidated financial statements and related notes included in this Annual Report on Form 10-K.

Overview

CoStar Group, Inc. (“CoStar”(the “Company” or “CoStar”) is the number one provider of information, marketinganalytics and analyticmarketing services to the commercial real estate industry in the United States ("U.S.") and the United Kingdom ("U.K.") based on the fact that we offer the most comprehensive commercial real estate database available,available; have the largest research department in the industry,industry; own and operate the leading online marketplace for commercial real estate in the U.S. based on the number of unique visitors per month; provide more information, marketinganalytics and analyticmarketing services than any of our competitors and believe that we generate more revenues than any of our competitors. We have created aand compiled our standardized information, marketinganalytics and analyticmarketing platform where 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 informati oninformation about space available for lease, comparable sales information, tenant information, information about properties for sale, tenant information, internet marketing services, analytical capabilities, information for clients' websites, information about industry professionals and their business relationships, data integration and industry news.

LoopNet, our subsidiary, operates an online marketplace that enables property owners, landlords, and commercial real estate agents working on their behalf to list properties for sale or for lease and to submit detailed information about property listings. Commercial real estate agents, buyers and tenants also use LoopNet's online marketplace to search for available property listings that meet their criteria.

We also provide market research and analysis for commercial real estate investors and lenders via our PPRProperty and Portfolio Research (“PPR”) service offerings, and portfolio and debt management and reporting capabilities through our Resolve Technology service offerings, and real estate and lease management solutions, including lease administration and abstraction services, through our Virtual Premise service offerings.

Our service offerings span all commercial property types, including office, industrial, retail, land, mixed-use, hospitality and multifamily.

Since 1994,Subscription-Based Services

Our subscription-based information services consist primarily of CoStar SuiteTM and FOCUSTM services. CoStar Suite is sold as a platform of service offerings consisting of CoStar Property Professional®, CoStar COMPS Professional®and CoStar Tenant® and through our mobile application, CoStarGo®. CoStar Suite is our primary service offering in our U.S. operating segment. FOCUS is our primary service offering in our International operating segment. Additionally, we have expanded the geographical coverage of our existing information and marketing services and developed new information, marketing and analytic 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 baseintroduced CoStar Suite in the U.K. with our acquisitionin the fourth quarter of London-based2012 and no longer offered FOCUS Information Limited. In May 2004, we expanded into Tennessee through the acquisition of Peer Market Research, Inc., andto new clients beginning in September 2004, we extended our coverage of the U.K. through the acquisition of Scottish Property Network. In September 2004, we strengthened our position in Denver, Colorado through the acquisition of substantially all of the assets of RealComp, Inc., a local comparable sales information provider.2013.

In January 2005, we acquired National Research Bureau, a Connecticut-based providerOur subscription-based services consist primarily 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 consultingsimilar 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 facilitatesoffered over 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. Most recently, in July 2009, we acquired Massachusetts-based Property and Portfolio Research, Inc. (“PPR”), a provider of real estate analysis, market forecasts and credit risk analyticsInternet to the commercial real estate industry and its wholly ownedrelated professionals. Our services are typically distributed to our clients under subscription-based license agreements that renew automatically, a majority of which have a term of one year. Upon renewal, many of the subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations. To encourage clients to use our services regularly, we generally charge a fixed monthly amount for our subscription-based information services rather than charging 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.


31



As of December 31, 2012 and 2013, our annualized net new sales of subscription-based services on annual contracts were approximately $10.9 million and $15.8 million, respectively, calculated based on the annualized amount of change in our sales resulting from new annual subscription-based contracts or upsales on existing annual subscription-based contracts, less write downs and cancellations, for the period reported. We recognize subscription revenue on a straight-line basis over the life of the contract. Annual and quarterly advance payments result in deferred revenue, substantially reducing the working capital requirements generated by accounts receivable.

For the twelve months ended December 31, 2012 and 2013, our contract renewal rate for existing CoStar subscription-based services was approximately 94% and 93%, respectively, and therefore our cancellation rate for those services was approximately 6% and 7%, respectively, for the same time periods. Our contract renewal rate is a quantitative measurement that is typically closely correlated with our revenue results. As a result, management also believes that the rate may be a reliable indicator of short-term and long-term performance. Our trailing twelve-month contract renewal rate may decline if, among other reasons, negative economic conditions lead to greater business failures and/or consolidations among our clients, reductions in customer spending, or decreases in our customer base.

Expansion and Development

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

In October 2013, we introduced technology enhancements to CoStar Suite, our platform of service offerings consisting of CoStar Property Professional, CoStar COMPS Professionaland CoStar Tenant. The enhancements improve CoStar Suite's user interface, search functionality and analytic capabilities. The newly introduced CoStar MultifamilyTM information search allows access to our extensive multifamily property database. In addition, we introduced CoStar Lease AnalysisTM, an integrated workflow tool that provides users a simple way to produce understandable cash flows for any proposed or existing lease. We will continue software development on our new Lease Analysis workflow tool throughout 2014. We believe this greater functionality will make our services valuable to an even broader audience and help us increase sales of our services to brokers, banks, owners and institutional investors. Further, these technology enhancements are expected to drive continued revenue growth in 2014 and for the foreseeable future. We expect additional selling and marketing activities to promote our new service enhancements will result in increased expenses in 2014.

In October 2013, we also released CoStarGo® 2.0, the next generation of our mobile application, which was launched in the U.S. on August 15, 2011 and introduced in the U.K. subsidiary Propertyon November 5, 2012. CoStarGo is our iPad application that integrates and Portfolio Research Ltd.,provides CoStar Suite subscribers mobile access to our comprehensive property, tenant and in October 2009, we acquired Massachusetts-based Resolve Technology, a provider of business intelligence and portfolio management software serving the institutional real estate investment industry. The PPR and Resolve Technology acquisitions are discussed later in this section under the heading “Recent Acquisitions.”comparable sales information. CoStarGo 2.0 adds powerful analytic capabilities to our comprehensive mobile solution.
27


We have consistently workedintroduced enhancements to expand our flagship marketing platform, LoopNet.com. For example, we added a broker advertising service offerings, boththat allows brokers to purchase advertisements based on geographic and property type criteria. Additionally, we introduced ProVideo, a service that enables owners and brokers to enhance their listings with high quality videos of interior spaces, amenities and exterior features. We expect to continue software development to improve the LoopNet marketing platform in terms2014.

We continue to integrate, develop and cross-sell the services offered by the companies we acquired, including LoopNet, Virtual Premise, Resolve Technology and PPR. In some cases, when integrating and coordinating our services and assessing industry needs, we may decide, or may have previously decided, to combine, shift focus from, de-emphasize, phase out, or eliminate a service that overlaps or is redundant with other services we offer.

Our sales and marketing efforts have focused and will continue to focus on cross-selling and marketing our services. We recently implemented an automatic cross-selling initiative within the LoopNet marketplace. As searchers view properties within the LoopNet marketplace, a message may appear indicating that there are additional listings available within CoStar Suite with the same search criteria that they are not able to access under their current subscription. The message provides contact information, so that the customer can reach their customer service or sales representative and review the most appropriate service for their needs. Our goal is to upsell clients to the services that best meet their needs and to create further cross-selling revenue synergies. In addition, we have added a comparison feature to CoStarGo, which allows our sales force to demonstrate how many more properties a prospect could see with respect to a particular search area if that prospect were using CoStar Suite rather than the prospect’s current subscription with LoopNet.

Our revenues have increased as a result of geographical coveragethe LoopNet merger and prior acquisitions, due to revenue from the acquired businesses and from cross-selling opportunities among the customers of CoStar and the scopeacquired companies. As a result of cross selling CoStar's and LoopNet's complementary services, offered,we began to achieve increased revenue synergies in order2013. We also incurred increased expenses associated with the related marketing and sales campaign in 2012 and during the first half of 2013. These initiatives resulted in revenue growth, and we expect they will continue to position the company for future revenue growth.  In 2004, we began our expansion into 21 new metropolitan markets throughoutgrowth during 2014 and for the U.S. and began 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 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.foreseeable future.

During the second half of 2006, in order 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., we increased our U.S. field research fleet by adding 89 vehicles and we hired researchers to staff these vehicles. We released our CoStar Property Professional service in the 81 new CBSAs across the U.S. in the fourth quarter of 2007. Throughout our recent expansion efforts, we have remained focused on ensuring that CoStar continues to provide the quality of information our customers expect. As such, in 2010 we expanded our research operations, and we plan to continue to grow our research operations slightly in 2011 in order to continue to meet customer expectations.

During the second half of 2009, as a part of our strategy to provide subscribers with tools for conducting primary research and analysis on commercial real estate, we expanded subscribers’ capabilities to use CoStar’s database of research-verified commercial property information to conduct in-depth analysis and generate reports on trends in sales and leasing activity online. Further, in July 2009, we acquired PPR and its wholly owned subsidiary, providers of real estate investment analysis and market forecasting services.

In connection with our acquisitions of Propex, Grecam and PPR’s wholly owned subsidiary Property and Portfolio Research Ltd., we intend to expand the coverage of our service offerings within the U.K. and to integrate our international operations more fully with those in the U.S. We have gained operational efficiencies as a resultintend to continue to upgrade the platform of consolidating a majorityservices and expand the coverage of our service offerings within our International segment. To further develop those initiatives, we introduced CoStar Suite in the U.K. research operationsduring the fourth quarter of 2012 and no longer offered FOCUS to new clients beginning 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 introduce2013. CoStar Suite is sold as a consistent international platform of service offerings. In 2007, we introducedofferings consisting of CoStar Property Professional, CoStar COMPS Professionaland CoStar Tenant and through the “CoStar Group” as the brand encompassing our international operations, and in early 2010 we launched Showcase, our Internet marketing service that provides commercial real estate professionals the opportunity to make their listings accessible to all visitors to our public websites,Company's mobile application, CoStarGo. CoStarGo 2.0 was released in the U.K. in October 2013 simultaneous with the release in the U.S. Additionally, we have upgraded our back-end research operations, fulfillment and Customer Relationship Management (“CRM”) systems to support these new U.K. services. In order to implement these services in the U.K., we incurred increased development costs through 2012; however, development costs incurred by the International segment decreased in 2013. The International operating segment continues to experience improved financial performance and most recently, during the three months ended December 31, 2013, International EBITDA increased to a positive amount as a result of increased revenue and decreased operating expenses.

In 2014, we expect to expand further internationally by offering our services in Toronto, Canada. We believe that our recent U.S.integration efforts and internationalcontinued investments in our services, including expansion and integration effortsof our existing service offerings internationally, have created a platform for long-term growth, which werevenue growth. We expect these investments to result in further penetration of our international subscription-based information services and the successful cross-selling of our services to customers in existing markets.

We intend to continue to develop, investassess the need for additional investments in and expand.

We expectour business, in addition to continuethe investments discussed above in order to develop and distribute new services expand existing services within our current platform, and expand and develop our sales and marketing organization. For instance, in July 2009, we expanded subscribers’ analytic capabilities to use our online database to conduct in-depth analysis and generate reports on sales and leasing activity through our acquisition of PPR and in October 2009, we acquired Resolve Technology, which enabled us to provide our customers with additional tools for analyzing commercial real estate markets.platform. Any future product development or expansion including expansion through acquisitionsof services, combination and expansion internationally,coordination of services or elimination of services could reduce our profitability and increase our capital expenditures. Therefore, while we expect current service offerings to remain profitable, driving overall earnings throughout 2011in 2014 and pro vidingproviding substantial cash flow for our business, it is possible that any new investments, changes to our service offerings or other unforeseen events could cause us to generate losses and negative cash flow from operations in the future. Further, our credit facilities contain restrictive covenants that restrict our operations and use of our cash flow, which may prevent us from taking certain actions that we believe could increase our profitability or otherwise enhance our business.

Our goal is to provide additional tools that make our researchMarket Conditions

In general, the current economic recovery has been slower than past economic recoveries. Job growth, in particular, has recovered more slowly than in past economic recoveries, and analytics even more valuable to subscribers.  For example, we are currently focusing on integration and further development of the PPR and Resolve Technology service offerings.  We have launched an initiative to develop a discounted cash flow (DCF) forecasting and valuation solution that effectively integrates the combined capabilities of CoStar’s market and property information and PPR’s analytics and forecasting expertise with Resolve Technology’s real estate investment software expertise.  In order to implement this initiative, we have incurred, and expect to continue to incur additional costs, including costs of hiring additional personnel.  While our investments in PPR and Resolve Technology have resulted a nd may continue to result in an increase in expenses, our revenues have also increased as a result, the improvement in the commercial real estate industry has been slower, especially with respect to the rental rate growth.  Continuing near-term risks related to lower-than-expected job growth, government fiscal challenges, and uncertainty over U.S. and global economic issues may impede the ability and willingness of these acquisitions, and we have experienced increased cross-selling opportunities among CoStar and the acquired companies.

In some cases, the business operationsclients to purchase services from us or result in reductions of someservices purchased. Additionally, since many of our clients continueuse debt to be negatively affected by challenging economic conditionsfinance a portion of their real estate purchases, material changes in interest rates and risk premiums could harm their ability to complete transactions, especially if the change was relatively rapid and unexpected.
As is typical of this point in the U.S. and the world, resulting at times ineconomic cycle, business consolidations, and in some circumstances, business failure.failures, continue to occur. If cancellations, reductions of services, and failures to pay continue at the current rate or increase, and we are unable to offset the resulting decrease in revenue by increasing sales to new or existing customers, our revenues may decline or grow at reducedlower rates.  Additionally, current economic conditions may cause customers to reduce expenses, and customers may be forced to purchase fewer services from us or cancel all services. We compete against many other commercial real estate information, marketinganalytics, and analyticmarketing service providers for busine ss.business, including competitors that offer rapidly changing methods of delivering real estate information. If customers choose to cancel our services for cost-cuttingbecause of cost cutting, desire to access real estate information through other delivery methods, or other reasons, our revenue could decline.


There are clear signs of improving conditions in the commercial real estate industry, including heightened leasing activity and positive net absorption of office space, resulting from modest office-related job growth and recent business expansions in the U.S.  The extent and duration of continued improvement of the economy and the commercial real estate industry is unknown, as is the extent and duration of any benefits resulting from any of the governmental or private sector initiatives designed to strengthen the economy.  Because of these uncertainties and any resulting impact on our business, we may not be able to accurately forecast our revenue or earnings.  Based on current economic conditions, we believe that the Company is positioned to generate continued, sustained earnings from current operations in 2011 and for the foreseeable future.

Financial Matters

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

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

We recently decided to take advantage of favorable market conditions to lower our long-term occupancy costs as a tenant.  As part of our overall strategy to consolidate our London office locations and reduce occupancy costs, we relocated our London offices and in July 2010 entered into a settlement pursuant to which we terminated our lease for our former London offices.  In addition, in September 2010, we consolidated our three facilities located inFebruary 2012, the Boston, Massachusetts area, including the facilities used by CoStar, PPR and Resolve Technology, into one facility. We recorded a lease restructuring charge of approximately $1.3 million in general and administrative expense in the third quarter of 2010 as a resultCompensation Committee (the “Committee”) of the Boston office consolidation.  In December 2010, we consolidated our New York and Isel in, New Jersey offices into one facility.  The consolidationBoard of these facilities did not result in a lease restructuring charge.

On February 5, 2010, we took advantageDirectors approved grants of favorable market conditions and purchased an office building in downtown Washington, DC for $41.25 million for use as our new headquarters and have since relocated to this location.  The lease for our previous headquarters in Bethesda, MD expired on October 15, 2010; therefore, we incurred overlapping occupancy costs through the end of the Bethesda lease term as we transitionedrestricted common stock to our new headquarters.  We were able to create value through our occupancy of the building in Washington, DC and on February 18, 2011 sold the building for aggregate consideration of $101.0 million, $15.0 million of which is being held in escrow to fund additional build-out and planned improvements at the building.  As part of the sale, we entered into a long-term lease with the buye r to lease back approximately 88% of the office space, where our corporate headquarters will remain.  We expectexecutive officers that the lease-back arrangement will result in additional expense of approximately $4.5 million to $5.0 million in 2011.

 Our subscription-based information services, consisting primarily of CoStar Property Professional, CoStar Tenant, CoStar COMPS Professional, and FOCUS services currently generate more than 94% 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. The majority of our contracts for our subscription-based information services typically have a minimum term of one year and renew automatically. Upon renewal, many of the subscription contract rates may change in accordance with contract provisions or as a result of contract renegotiations. To encourage clients to use our services regu larly, we generally charge a fixed monthly amount for our subscription-based information services rather than fees based on actual system usage. Contract rates are generallyvest based on the numberachievement of sites, numberCoStar performance conditions. Specifically, these shares of users, organization size,performance-based restricted common stock vest upon our achievement of $90.0 million of cumulative net income before interest, income taxes, depreciation and amortization ("EBITDA") over a period of four consecutive calendar quarters, and are subject to forfeiture in the client’s business focus, geographyevent the foregoing performance condition is not met by March 31, 2017. These awards support the Committee’s goals of aligning executive incentives with long-term stockholder value and ensuring that executive officers have a continuing stake in the numberlong-term success of services to which a client subscribes. Our subscription clients generally pay contract feesCoStar. In May and December of 2012, we granted additional shares of restricted common stock that vest based 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 lifeachievement of the contract. Annual and quarterly advance payments result in deferred revenue, substantially reducingsame performance conditions to other key employees. We granted a total of 399,413 shares of performance-based restricted common stock during the working capital requirements generated by accounts receivable.

Foryear ended December 31, 2012. There was no performance-based restricted common stock granted during the twelve monthsyear ended December 31, 20102013. All of the awards were made under the CoStar Group, Inc. 2007 Stock Incentive Plan and 2009,pursuant to our contract renewal ratestandard form of restricted stock grant agreement. The number of shares granted was based on the fair market value of CoStar’s common stock on the grant date. As of March 31, 2013, we initially determined that it was probable that the performance condition for subscription-based servicesthese performance-based restricted common stock awards would be met by the March 31, 2017 forfeiture date. As of December 31, 2013, we reassessed the probability of achieving this performance condition and determined that it was still probable that the performance condition for these awards would be met by the March 31, 2017 forfeiture date, subject to certain approvals under the CoStar Group, Inc. 2007 Stock Incentive Plan. As a result,we recorded a total of approximately 90% and 85%, respectively, and therefore our cancellation rate was approximately 10% and 15%, respectively,$21.8 million of stock-based compensation expense related to performance-based restricted common stock for the same periodsyear ended December 31, 2013. There was no stock-based compensation expense related to performance-based restricted common stock recorded for the years ended December 31, 2011 and 2012.

Property Developments

As in the past, we expect to continue to identify new facilities and consolidate existing facilities to better accommodate the changing demands of time.  Our contract renewal rate is a quantitative measurement that is typically closely correlated with our revenue results.business and employees. As a result, management also believes thatwe may incur additional lease restructuring charges for the rate may be a reliable indicatorabandonment of short-termcertain lease space and long-term performance.  Our trailing twelve-month contract renewal rate may decline if negative economic conditions lead to greater business failures and/or consolidations among our clients, further reductions in customer spending, or decreases in our customer base.the impairment of leasehold improvements.

Application of Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. The following accounting policies involve a “critical accounting estimate” because they are particularly dependent on estimates and assumptions made by management about matters that are highly uncertain at the time the accounting estimates are made. In addition, while we have used our best estimates based on facts and circumstances available to us at the time, different acceptable assumptions would yield different result s.results. 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.

Fair Value of Auction Rate Securities

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

Our ARS investments are not currently actively trading and therefore do not currently have a readily determinable market value. Accordingly, theThe 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, 2010.2013. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of contractual cash flows, liquidity risk premiums, expected holding periods and default risk of the ARS. We update the discounted cash flow model on a quarterly basis to reflect any changes in the assumptions used in the model and settlements of ARS investments that occurred during the period.

The only significant unobservable input in the discounted cash flow model is the discount rate. The discount rate used represents our estimate of the yield expected by a market participant from the ARS investments. The weighted average discount rate used in the discounted cash flow model as of December 31, 2012 and 2013 was approximately 5.1% and 4.9%, respectively. Selecting another discount rate within the range used in the discounted cash flow model would not result in a significant change to the fair value of the ARS.

Based on this assessment of fair value, as of December 31, 2010,2013, we determined there was a decline in the fair value of our ARS investments of approximately $3.0 million.$1.5 million. The decline was deemed to be a temporary impair mentimpairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. If the issuers of these ARS are unable to successfully close future auctions and/or their credit ratings deteriorate, we may be required to record additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments, which would reduce our profitability and adversely affect our financial position.

30

We have not made any material changes in the accounting methodology used to determine the fair value of the ARS. We do not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used to calculate the fair value of the ARS as of December 31, 2010.2013. However, if changes in these assumptions occur, and, should those changes be significant, we may be exposed to additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments.

Fair Value of Deferred Consideration

Our Level 3 liabilities consist of a $3.2 million liability as of December 31, 2010 for deferred consideration related to the October 19, 2009 acquisition of Resolve Technology. The deferred consideration is for (i) a potential deferred cash payment two years after closing based on the incremental growth of Resolve Technology’s revenue, and (ii) other potential deferred cash payments for successful completion of operational and sales milestones during the period from closing through October 31, 2013, which period may be extended by the parties to a date no later than December 31, 2014.

We used a discounted cash flow model to determine the estimated fair value of our Level 3 liabilities as of December 31, 2010.  The significant assumptions used in preparing the discounted cash flow model include the discount rate, estimates for future incremental revenue growth and probabilities for completion of operational and sales milestones.

We have not made any material changes in the accounting methodology used to determine the fair value of the deferred consideration.  We do not expect any material changes in the near term to the underlying assumptions used to determine the unobservable inputs used to calculate the fair value of the deferred consideration as of December 31, 2010.  However, if changes in these assumptions occur, and, should those changes be significant, we may be required to recognize additional liabilities related to this deferred consideration.

Stock-Based Compensation

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

We do not expect any material changes in the near term to the underlying assumptions used to calculate stock-based compensation expense for the twelve monthsyear ended December 31, 2010.2013. However, if changes in these assumptions occur, and, should those changes be significant, they could have a material impact on our stock-based compensation expense.

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.

31

When we determine that the carrying value of long-lived and identifiable intangible assets may not be recovered based upon the existence of one or more of the above indicators, we test for impairment.

Goodwill and identifiable intangible assets that are not subject to amortization are tested annually for impairment by each reporting unit on October 1 of each year and are also tested for impairment more frequently based upon the existence of one or more of the above indicators. We consider our operating segments, U.S. and International, as our reporting units under FASBFinancial Accounting Standards Board ("FASB") authoritative guidance for consideration of potential impairment of goodwill.

TheTo determine whether it is necessary to perform the two-step goodwill impairment test, we may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if we elect not to assess qualitative factors, then we perform the two-step process. The first step is to determine the fair value of each reporting unit. We estimate the fair value of each reporting unit based on a projected discounted cash flow model that includes significant assumptions and estimates including our discount rate, growth rate and future financial performance andperformance. Assumptions about the discount rate are based on a weighted average cost of capital. capital for comparable companies. Assumptions about the growth rate and future financial performance of a reporting unit are based on our forecasts, business plans, economic projections and anticipated future cash flows. Our assumptions regarding the future financial performance of the International reporting unit reflect our expectation as of October 1, 2013, that revenues will increase as a result of further penetration of our international subscription-based information services and the successful cross-selling of our services to our customers in existing markets due to the release of our upgraded international platform and expansion of coverage of our international service offerings. These assumptions are subject to change from period to period and could be adversely impacted by the uncertainty surrounding global market conditions, commercial real estate conditions, and the competitive environment in which we operate. Changes in these or other factors could negatively affect our reporting units' fair value and potentially result in impairment charges. Such impairment charges could have an adverse effect on our results of operations.

The fair value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then the second step of the process is performed to measure the impairment loss. We 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. As of October 1, 2010,2013, the date of our most recent impairment analysis, the estimated fair value of each of our reporting units substantially exceeded the carrying value of our reporting units. There have been no events or changes in circumstances since the date of our impairment analysis on October 1, 20102013 that would indicate that the carrying value of each reporting unit may not be recoverable.

To determine whether it is necessary to perform the quantitative impairment test for indefinite-lived intangible assets, we may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of the indefinite-lived intangible assets is less than the carrying amount. If we conclude that it is more likely than not that the fair value of the indefinite-lived intangible assets is less than the carrying amount or if we elect not to assess qualitative factors, then we perform the quantitative impairment test similar to the test performed on goodwill discussed above.

As of October 1, 2013, the date of our most recent impairment analysis, the estimated fair value of our indefinite-lived intangible assets substantially exceeded the carrying value. There have been no events or changes in circumstances since the date of our impairment analysis on October 1, 2013 that would indicate that the carrying value of the indefinite-lived intangible asset may not be recoverable.

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 consolidated statements of operations.

Non-GAAP Financial Measures

We prepare and publicly release quarterly unaudited financial statements prepared in accordance with GAAP. We also disclose and discuss certain non-GAAP financial measures in our public releases, investor conference calls and filings with the Securities and Exchange Commission. The non-GAAP financial measures that we may disclose include EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share.share (also referred to as "non-GAAP EPS"). EBITDA is our net income (loss) before interest, income taxes, depreciation and amortization. We typically disclose EBITDA on a consolidated and an operating segment basis in our earnings releases, investor conference calls and filings with the Securities and Exchange Commission. Adjusted EBITDA is different from EBITDA because we further adjust EBITDA for stock-based compensation expense, acquisition re latedacquisition- and integration-related costs, restructuring costs, headquarters acquisition and transition related costs and settlements and impairments incurred outside our ordinary course of business. Non-GAAP net income and non-GAAP net income per diluted share are similarly adjusted for stock-based compensation expense, acquisition relatedacquisition- and integration-related costs, restructuring costs, headquarters acquisition and transition related costs and settlement and impairment costs incurred outside our ordinary course of business as well as purchase amortization and other related costs. We may disclose adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share on a consolidated basis in our earnings releases, investor conference calls and filings with the Securities and Exchange Commission. The non-GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help our investors more meaningfully evaluate and compare our results of operations to our previously reported results of operations or to those of other companies in our industry.
32


We view EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share as operating performance measures and as such we believe that the most directly comparable GAAP financial measure is net income (loss).income. In calculating EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share, we exclude from net income (loss) the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share are not measurements of financial performance u nderunder GAAP and should not be considered as a measure of liquidity, as an alternative to net income (loss) or as an indicator of any other measure of performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share as a substitute for any GAAP financial measure, including net income (loss).income. In addition, we urge investors and potential investors in our securities to carefully review the GAAP financial information included as part of our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q that are filed with the Securities and Exchange Commission, as well as our quarterly earnings releases, and compare the GAAP financial information with our EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share.


37



EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share may be used by management to internally measure our operating and management performance and may be used by investors as supplemental financial measures to evaluate the performance of our business.  We believe that these non-GAAP measures, when viewed with our GAAP results and the accompanying reconciliation, provide additional information that is useful to understand the factors and trends affecting our business. We have spent more than 2326 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, marketinganalytics and analyticmarketing services, which has included acquisitions, our net income (loss) has inclu dedincluded significant charges for purchase amortization, depreciation and other amortization, acquisitionacquisition- and integration-related costs and restructuring costs. EBITDA, adjustedAdjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share exclude these charges and provide meaningful information about the operating performance of our business, apart from charges for purchase amortization, depreciation and other amortization, acquisitionacquisition- and integration-related costs, restructuring costs and settlement and impairment costs incurred outside our ordinary course of business. We believe the disclosure of these non-GAAP measures can help investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe thesethe non-GAAP measures we disclose are measures of our ongoing operating performance because the isolation of non-cash charges, such as amortization and depreciation, and other items, such as interest, income taxes, stock-based compensation expenses, acquisition costs, headquarters acquisitionacquisition- and transition relatedintegration-related costs, restructuring costs and settlement and impairment costs incurred outside our ordinary course of business, provides additional information about our cost structure, and, over time, helps track our operating progress. In addition, investors, securities analysts and others have regularly relied on EBITDA and may rely on adjusted EBITDA, non-GAAP net income or non-GAAP net income per diluted share to provide a financial measure by which to compare our operating performance against that of other companies in our industry.

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

·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.The amount of interest income we generate may be useful for investors to consider and may result in current cash inflows. However, we do not consider the amount of net interest income to be a representative component of the day-to-day operating performance of our business.
33

·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.

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

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


38



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

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

·Stock-based compensation expense may be useful for investors to consider because it represents a portion of the compensation of our employees and executives. Determining the fair value of the stock-based instruments involves a high degree of judgment and estimation and the expenses recorded may bear little resemblance to the actual value realized upon the future exercise or termination of the related stock-based awards. Therefore, we believe it is useful to exclude stock-based compensation in order to better understand the long-term performance of our core business.

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

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

·The amount of headquarters acquisition and transition related costs incurred may be useful for investors to consider because they generally represent the overlapping rent and building carrying costs, legal costs and other related costs incurred to relocate our headquarters.The amount of material settlement and impairment costs incurred outside of our ordinary course of business may be useful for investors to consider because they generally represent gains or losses from the settlement of litigation matters. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.

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

The financial items that have been excluded from our net income (loss) to calculate non-GAAP net income and non-GAAP net income per diluted share are purchase amortization and other related costs, stock-based compensation, acquisition relatedacquisition- and integration-related costs, restructuring costs, headquarter acquisition and transition related costs and settlement and impairment costs incurred outside our ordinary course of business. These items are discussed above with respect to the calculation of adjusted EBITDA alongtogether with the material limitations associated with using this non-GAAP financial measure as compared to net income (loss).income. We subtract an assumed provision for income taxes to calculate non-GAAP net income. We assumeIn 2011, we assumed a 40% tax rate, and in 2012 and 2013, we assumed a 38% tax rate in order to approximate our long-term effective corporate tax rate.

Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share.

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

Recent Acquisitions

LoopNetPPR. On July 17, 2009,April 30, 2012, we acquired all100% of the issuedoutstanding stock of LoopNet pursuant to an Agreement and outstandingPlan of Merger dated April 27, 2011, as amended May 20, 2011 (the “Merger Agreement”). We paid approximately $746.4 million in cash and approximately $137.1 million in equity, securitiesfor a total consideration of PPR,$883.4 million.

Accounting Treatment. We have applied the acquisition method to account for the LoopNet transaction which requires that, among other things, assets acquired and its wholly owned subsidiary Property and Portfolio Research Ltd., providers of real estate analysis, market forecasts and credit risk analytics to the commercial real estate industry. We acquired PPR from DMG Information, Inc. (“DMGI”) in exchange for 572,999 shares of CoStar common stock, which had an aggregate value of approximately $20.9 millionliabilities assumed be recorded at their fair values as of the closingacquisition date. On July 17, 2009, we issued 433,667 shares of our common stock to DMGI, and we issued the remaining 139,332 shares to DMGI on September 28, 2009 after taking into account post-closing purchase price adjustments.

Resolve Technology. On October 19, 2009, we acquired all of the outstanding capital stock of Resolve Technology, a Delaware corporation, for approximately $4.5 million, consisting of approximately $3.4 million in cash and 25,886 shares of CoStar common stock, which had an aggregate value of approximately $1.1 million as of the closing date.  The shares are subject to a three-year lockup, pursuant to which one-third were released in October 2010.  The purchase price is subject to certain post-closing adjustments.  Additionally, the seller may be entitled to receive (i) a potential deferred cash payment due approximately two years after closing based on the incremental growth of Resolve Technology’s revenue as of September 2011 over its revenue as of September 2009, and (ii) other potential deferred cash payments for successful completion of operational and sales milestones during the period from closing through no later than October 31, 2013, which period may be extended by the parties to a date no later than December 31, 2014.

Accounting Treatment. These acquisitions were accounted for as purchase business combinations.  For each of the PPR and Resolve Technology acquisitions, the purchase price was allocated to various working capital accounts, developed technology,trade names, customer base, trademarks, non-competition agreementsdatabase technology, goodwill and goodwill.various other asset and liability accounts. The acquired trade names recorded in connection with the LoopNet acquisition have an indefinite estimated useful life and are not amortized, but are subject to annual impairment tests. The acquired customer base for the acquisitions,acquisition, 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 methodan accelerated basis related to the expected economic benefit of the intangible asset over ten years. The identified intangibles are amortized over theirthe estimated useful lives.life. The acquired database technology for the acquisition is amortized on a straight-line basis over the estimated useful life. Goodwill for these acquisitionsthe acquisition is not amortized, but is subject to annual impairment tests. The results of operations of PPR and Resolve TechnologyLoopNet have been consolidated with those of the Company since the respective datesdate of the acquisitions and are not considered material to our consolidated financial statements. Accordingly, pro forma financial information has not been presented for anyacquisition. See Note 3 of the acquisitions.Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for further details on the LoopNet acquisition.

Liquidity and Capital Resources

Our principal sources of liquidity are cash, cash equivalents and short-term investments.debt from our term loan and revolving credit facility. Total cash and cash equivalents were $256.0 million at December 31, 2013 compared to cash, cash equivalents and short-term investments were $210.1of $156.1 million at December 31, 2010 compared to $226.0 million at December 31, 2009.2012. The decreaseincrease in cash, cash equivalents and short-term investments for the year ended December 31, 20102013 was primarily due to the purchase of a 169,429 square-foot office building located at 1331 L Street, NW in downtown Washington, DC for a purchase price of $41.25 million in cash, and approximately $1.7 million in acquisition costs, as well as other purchases of property and equipment of approximately $14.4 million, partially offset by net cash flows fromprovided by operating and financing activities of $41.3 million.$108.3 million.

39

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

Net cash provided by operating activities for the year ended December 31, 20102013 was $39.3$108.3 million compared to $38.5$86.1 million for the year ended December 31, 2009.2012. The $800,000 $22.2 millionincrease in net cash provided by operating activities is primarily due to an increase of approximately $12.5 million from net income plus non-cash items as well as a $4.4 million net increase of approximately $9.7 million in changes in operating assets and liabilities due to differences in timing of collection of receipts and payments of disbursements partially offset by a decrease of approximately $3.6 million from net income plus non-cash items.   The $4.4 million net increasedisbursements.

Net cash used in changes in operating assets and liabilities was primarily related to an increase in changes in accounts payable and other liabilities of approximately $5.2 million and approximately $3.0 million in increased change in deferred revenue primarily associated with cash received for annual bill ings.  The increase in the change in accounts payable and other liabilities of approximately $5.2 million includes increased changes in accruals of deferred rent of approximately $2.6 million, $800,000 accrued in June 2010 in anticipation of the settlement of a litigation matter, $900,000 remaining in the lease restructuring charge associated with our Boston lease consolidation in September 2010 and increased accruals associated with the operations of our recent acquisitions and new headquarters.  These increases in changes in operating assets and liabilities were partially offset by a decrease in the changes in income tax receivable of approximately $4.9 million, as the tax legislation enacted during the fourth quarter of 2010 allowed us to deduct 100% of qualifying assets purchased after September 8, 2010, resulting in an income tax receivable recorded investing activities for the year ended December 31, 2010.

Net cash used in investing activities2013 was $40.5$19.0 million compared to $640.4 million for the year ended December 31, 2010, compared to2012. This $621.4 milliondecrease in net cash provided byused in investing activities in 2013 was primarily due to $640.9 millionof $4.5cash used for the acquisition of LoopNet on April 30, 2012, partially offset by a decrease in the proceeds from the sale and settlements of investments of approximately $15.3 million.

Net cash provided by financing activities was $10.4 million for the year ended December 31, 2009.2013, compared to $164.9 million for the year ended December 31, 2012.  This $45.0$154.5 million increased changedecrease in net cash used in investingprovided by financing activities was primarily due to the February 2010 purchaseproceeds of our new headquarters$175.0 million received from the term loan facility on April 30, 2012 less payments of debt issuance costs of $11.5 million associated with the debt which did not occur in downtown Washington, DC, as well as capital improvements for our facilities in 2010, partially offset by the $3.2 million in net cash payments for acquisitions.2013.

Net cash provided by financing activities was relatively consistent at $2.0 million for the year ended December 31, 2010 compared to $2.2 million for the year ended December 31, 2009.

The lease is effective as of June 1, 2010 and will expire May 31, 2025. The initial base rent is $38.50 per square foot of occupied space, escalating 2.5% per year commencing June 1, 2011. Our obligation to pay rent increases proportionately over the course of the first year of the lease as certain scheduled completion dates for our build out, on a floor-by-floor basis, are reached.  Our occupied space under the lease will consist of the entire rented premises as of June 1, 2011, from and after which we will owe rent on the entire leased premises.  Annual lease payments for 2011 will be approximately $5.0 million.  This obligation is not included in the above December 31, 2010 contractual obligation table.


Our future capital requirements will depend on many factors, including, among others, our operating results, expansion and integration efforts, and our level of acquisition activity or other strategic transactions.

During 2013, we incurred capital expenditures of approximately $19.0 million. We expect to make aggregate capital expenditures in 2014 of approximately $18.0 million to $23.0 million, primarily related to the build out of leased office space.

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

On April 30, 2012, we acquired LoopNet pursuant to the Merger Agreement. Prior to completion of the LoopNet acquisition on April 26, 2012 the FTC accepted a consent order in connection with the LoopNet merger that was previously agreed to by CoStar and LoopNet. The consent order, which is publicly available on the FTC's website at www.ftc.gov, required, among other things, that CoStar and LoopNet divest LoopNet's minority interest in Xceligent. On March 28, 2012, CoStar and LoopNet entered into a Purchase Agreement to sell LoopNet's interest in Xceligent to DMGI. The parties closed the sale of LoopNet's interest in Xceligent to DMGI on May 3, 2012. We received $4.2 million in proceeds from the sale, which reflected the fair value of the investment at the time of sale and did not result in any gain on the sale of the investment.

We funded the cash portion of the consideration payable to LoopNet stockholders in the merger through a combination of cash on hand, including the net proceeds of approximately $247.9 million from an equity offering we completed in June 2011, and $175.0 million in proceeds from a term loan facility pursuant to the Credit Agreement, dated February 16, 2012, by and among CoStar, as borrower, CoStar Realty, as co-borrower, J.P. Morgan Bank, as administrative agent, and the other lenders thereto. In addition to the third quarter$175.0 million term loan facility, the Credit Agreement provides for a $50.0 million revolving credit facility, each with a term of 2009,five years. We made principal payments of approximately $4.4 million and $17.5 million for the years ended December 31, 2012 and 2013, respectively. As of December 31, 2013, maturities of our borrowings under the Credit Agreement for each of the next four years ended December 31, 2014 to 2017, are expected to be $24.1 million, $32.8 million, $61.3 million and $35.0 million, respectively.

The Credit Agreement requires us to maintain a Debt Service Coverage Ratio (as defined in the Credit Agreement) of at least 1.5 to 1.0 and a Total Leverage Ratio (as defined in the Credit Agreement) that does not exceed 2.75 to 1.00 during each of the three months ending December 31, 2013, March 31, 2014 and June 30, 2014; and 2.50 to 1.00 thereafter. The Credit Agreement also includes other covenants that were effective as of April 30, 2012, including covenants that, subject to certain exceptions, restrict our ability and the ability of our subsidiaries (i) to incur additional indebtedness, (ii) to create, incur, assume or permit to exist any liens, (iii) to enter into mergers, consolidations or similar transactions, (iv) to make investments and acquisitions, (v) to make certain dispositions of assets, (vi) to make dividends, distributions and prepayments of certain indebtedness, and (vii) to enter into certain transactions with affiliates. We were in compliance with the covenants in the Credit Agreement as of December 31, 2013.

Commencing with the fiscal year ending December 31, 2012, the Credit Agreement requires us to make an annual prepayment of the term loan facility equal to a percentage of Excess Cash Flow (as defined in the Credit Agreement) to reduce the principal amount outstanding under the term loan facility. The prepayment percentage is 50% when the Total Leverage Ratio exceeds 3.00 to 1.00; 25% when the Total Leverage Ratio is greater than 2.50 to 1.00 but equal to or less than 3.00 to 1.00; and 0% when the Total Leverage Ratio is equal to or less than 2.50 to 1.00. This prepayment requirement is reduced by the amount of prior voluntary prepayments during the respective fiscal year, subject to certain exceptions set forth in the Credit Agreement. The Excess Cash Flow payment, if required, is due within ten business days of the date on which the annual financial statements are delivered or required to be delivered to the lenders pursuant to the Credit Agreement. For the fiscal year ended December 31, 2013, we issued 572,999were not required to make an Excess Cash Flow payment.

In connection with obtaining the term loan facility, we incurred approximately $11.5 million in debt issuance costs, which were capitalized and are being amortized as interest expense over the term of the Credit Agreement using the effective interest method. The debt issuance costs are comprised of approximately $9.2 million in underwriting fees and approximately $2.3 million primarily related to legal fees associated with the debt issuance. 


46



As of December 31, 2012 and 2013, no amounts were outstanding under the revolving credit facility. Total interest expense for the term loan facility was approximately $0, $4.8 million and $6.9 million for the years ended December 31, 2011, 2012 and 2013, respectively. Interest expense included amortized debt issuance costs of approximately $0, $2.0 million and $3.0 million for the years ended December 31, 2011, 2012 and 2013, respectively. Pursuant to the terms of the Credit Agreement, we are required to make interest payments on the term loan facility at a variable rate of interest and during interest periods selected by us as described in Note 9 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Total interest paid for the term loan facility was approximately $0, $2.5 million and $4.3 million for the years ended December 31, 2011, 2012 and 2013, respectively.

In 2012, we granted a total of 399,413 shares ofpursuant to performance-based restricted common stock to DMGI, Inc. for allawards with a forfeiture date of March 31, 2017. Upon vesting of these awards, consistent with tax minimum withholding requirements, a portion of the issued and outstanding capital stockshares subject to the awards will be remitted by the employees for payment of PPR and its wholly owned subsidiary.  In October 2009, we acquired Resolve Technology for approximately $3.4 million ($2.9 million was paid upon acquisition and $450,000 was deferred until February 2010) in cash and 25,886 shares of CoStar common stock, which had an aggregate value of approximately $1.1 million as of the closing date.their individual income tax obligations. The shares are subjectremitted will be canceled and we will make a cash tax payment equivalent to a three-year lockup, pursuant t o which one-third were released in October 2010.  Additionally, the seller maycanceled shares, currently estimated to be entitled to receive (i) a potential deferredapproximately $30.0 million. This amount is based on several assumptions, including the estimated stock price at the time of vesting as well as the individual minimum withholding rates for the employees. If the actual stock price and individual tax rates differ from these estimates, the cash payment due approximately two years after closing based on the incremental growth of Resolve Technology’s revenue as of September 2011 over its revenue as of September 2009, and (ii) other potential deferred cash payments for successful completion of additional operational and sales milestones during the period from closing through October 31, 2013, which period may be extended by the parties to a date no later than December 31, 2014.change.

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, 2010,2013, we had $32.2$24.3 million par value of long-term investments in student loan ARS, which failed to settle at auctions. The majority of these investments are of high credit quality with AAA credit ratings and are primarily securities supported by guarantees from the Federal Family Education Loan Program (“FFELP”)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.short-term. In the event we need to immediately access these funds, we may have to sell these securities at an amount below par value. Based on our ability to access our cash and cash equivalents and other short-term investments and our expected operating cash flows, we do not anticipate having to sell these inv estmentsinvestments below par value in order to operate our business in the foreseeable future.
As more fully described in Note 11 of the Notes to Condensed Consolidated Financial Statements included in this Annual Report on Form 10-K, on January 3, 2012, LoopNet, our wholly owned subsidiary, was sued by CIVIX-DDI, LLC (“Civix”) for alleged patent infringement, and on or about May 14, 2012, Civix filed a motion for leave to amend its complaint against LoopNet seeking to add CoStar as a defendant, alleging that our products also infringe Civix's patents. The complaint seeks unspecified damages, attorneys' fees and costs. On June 21, 2012, we filed an action seeking a declaratory judgment of non-infringement and invalidity against Civix; we amended this complaint on August 14, 2012 to assert an affirmative claim against Civix for breach of contract, alleging Civix violated its license agreement and covenant not to sue with one of our technology licensors. On November 25, 2013, Civix submitted its expert’s report of damages, which estimated the payment it deemed appropriate in the event that we are found liable of infringement. We believe that Civix’s calculation of damages is based on improper assumptions and miscalculations, and is otherwise unsupported. We submitted our own expert’s report of damages, which concluded that the appropriate payment to be made in the event that we are found liable of infringement is significantly less than Civix’s estimate of appropriate damages. Moreover, our expert's report of damages concluded that while Civix’s calculation of damages was fundamentally flawed and should not be used to determine damages, simply applying certain necessary adjustments to Civix's calculation as outlined in our expert's report resulted in a significant reduction in Civix’s calculation of damages to approximately $3.7 million. On November 5, 2013 we offered to settle all outstanding litigation with Civix for $600,000. At this time we cannot predict the outcome of the litigation with Civix, but we intend to vigorously defend against Civix’s claims. While we believe we have meritorious defenses against Civix’s claims, we estimate that, based on our adjusted calculation of Civix’s alleged damages, the matter could result in a loss of up to $3.1 million in excess of the amount accrued.

On December 8, 2009, a former employee filed a lawsuit against us in the United States District Court for the Southern District of California alleging violations of the Fair Labor Standards Act and California state wage-and-hour laws and is seeking unspecified damages under those laws.  The complaint also seeks to declare a class of all similarly situated employees to pursue similar claims.  In May 2010, the parties reached a preliminary agreement to settle this lawsuit, and in June 2010, we accrued approximately $800,000 in anticipation of making a settlement payment that will formally resolve this litigation.  We anticipate the payment will be due during the second quarter of 2011.

Recent Accounting Pronouncements

In April 2008,July 2012, the FASB issued authoritative guidance on existing intangibles or expected future cash flows from those intangibles, whichto simplify how companies test indefinite-lived intangible assets for impairment. The guidance permits a company to first assess qualitative factors to determine whether it is effectivemore likely than not that an indefinite-lived intangible asset is impaired as a basis for all fiscal years and interim periods beginning after December 15, 2008. Early adoption of this guidance is not permitted. This guidance 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, this guidance requires that we consider our experience regarding renewal and extensions of similar arrangements in determining the useful life of such intangibles. If we do not have experience with similar arrangements, this guidance requires that we use the assumptions of a market participant putting the intangible to its highest and best use in determining the useful life. We adopted this guidance on January 1, 2009. The adoption of this guidance did not have a material impact on our results of operations or financial position.

In June 2008, the FASB issued authoritative guidance related to determining whether instruments granted in share-based payment transactions are participating securities.  This guidance clarifies that unvested share-based payment awards with a rightit is necessary to receive non-forfeitable dividends are participating securities.perform the quantitative impairment test. This guidance is effective for all annual and interim periodsimpairment tests performed for fiscal years beginning after DecemberSeptember 15, 2008. Adoption of this standard will require the two-class method of calculating basic earnings per share to the extent that unvested share-based payments have the right to receive non-forfeitable dividends.

In April 2009,February 2013, the FASB issued authoritative guidance related to improve the initial recognition, measurement and subsequent accounting for assets and liabilities arising from pre-acquisition contingencies in a business combination. It requires that such assets acquired or liabilities assumed be initially recognized at fair value at the acquisition date if fair value can be determined during the measurement period. When fair value cannot be determined, companies should typically account for the acquired contingencies using existing guidance.reporting of reclassifications out of accumulated other comprehensive income. This guidance requires that companies expense acquisition and deal-related costs that were previously alloweda company to present, either on the consolidated statements of operations or in the notes to the consolidated financial statements, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required under GAAP to be capitalized.  This guidance also requiresreclassified in its entirety to net income. For other amounts that a systematic and rational basis for subsequently measuring and accounting forare not required under GAAP to be reclassified in their entirety to net income in the assets or liabilities be developed depending on the ir nature. This guidance was effective for contingent assets or liabilities arising from business combinations withsame reporting period, an acquisition date on or after January 1, 2009.   The adoption of this guidance changes the accounting treatment and disclosure for certain specific items in a business combination with an acquisition date subsequententity is required to December 31, 2008.  We adopted this guidance on January 1, 2009, and expensed acquisition and deal-related costs associated primarily with the acquisitions of PPR and Resolve Technology.

In April 2009, the FASB issued authoritative guidance for determining whether a market is active or inactive, and whether a transaction is distressed.cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This guidance is applicable to all assetseffective prospectively for financial statements issued for interim and liabilities (financial and non-financial) and will require enhanced disclosures. We adopted this guidance for our interim period ending June 30, 2009. The adoption of thisannual periods beginning after December 15, 2012. This guidance did not have a material impact on our results of operations or financial position, but did requirewe provided additional disclosures in our financial statements.

In April 2009, the FASB issued authoritative guidance requiring disclosures in interim reporting periods concerning the fair value of financial instruments that were previously only required in the annual financial statements. We adopted the provisions of this guidance for our interim period ending June 30, 2009. The adoption of this guidance did not have a material impact on our results of operations or financial position, but did require additional disclosures in our financial statements.

In April 2009, the FASB issued authoritative guidance that redefines what constitutes an other-than-temporary impairment, defines credit and non-credit components of an other-than-temporary impairment, prescribes their financial statement treatment, and requires enhanced disclosures relating to such impairments. We adopted this guidance for our interim period ending June 30, 2009. The adoption of this guidance did not have a material impact on our results of operations or financial position, but did require additional disclosures in our financial statements.

In May 2009, the FASB issued authoritative guidance which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. This guidance was effective for all interim and annual reporting periods ending after June 15, 2009. This guidance has not and is not expected to result in significant changes in the subsequent events that we report, either through recognition or disclosure, in our financial statements.

In June 2009,July 2013, the FASB issued authoritative guidance to amendimprove the mannerreporting of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance requires a company to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in which entities evaluate whether consolidationthe financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. If a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is required for variable interest entities (VIE).  Previously, variable interest holders were required to determine whether they had a controlling financial interest in a VIE based on a quantitative analysisnot available at the reporting date or the tax law of the expected gains and/or losses ofapplicable jurisdiction does not require a company to use, and a company does not intend to use, the entity.  The new guidance requires an enterprise with a variable interest in a VIE to qualitatively assess whether it has a controlling financial interestdeferred tax asset for such purpose, the unrecognized tax benefit should be presented in the entity,financial statements as a liability and if so, whether it is the primary beneficiary.  This guidance also requires that companies continually evaluate VIEs for consolidation, rather than assessing whether consolidation is required based upon the occurrence of triggering events.  This guidance enhan ces disclosures to provide financial statement usersshould not be combined with greater transparency about transfers of financial assets and a transferor’s continuing involvement with transferred financialdeferred tax assets. This guidance will beis effective for the first annual reporting period beginning after November 15, 2009. This guidance did not materially impact our results of operations, financial position or related disclosures.

In June 2009, the FASB issued authoritative guidance which replaced the previous hierarchy of U.S. GAAP and establishes the FASB Codification as the single source of authoritative U.S. GAAP recognized by the FASB to be applied by nongovernmental entities. This guidance is effectiveprospectively for financial statements issued for interim and annual periods endingbeginning after SeptemberDecember 15, 2009. This guidance did not materially impact our results of operations or financial position, but did require changes to our disclosures in our financial statements.

In July 2009, the FASB issued authoritative guidance to improve the consistency2013 with which companies apply fair value measurements guidance to liabilities.early adoption and retrospective application permitted. This guidance is effective for interim and annual periods beginning after September 30, 2009.  This guidance did not materiallyexpected to have a material impact on our results of operations, financial position or related disclosures.

In October 2009, the FASB issued authoritative guidance that amends existing guidance for identifying separate deliverables in a revenue-generating transaction where multiple deliverables exist, and provides guidance for measuring and allocating revenue to one or more units of accounting.  In addition, the FASB issued authoritative guidance on arrangements that include software elements.  Under this guidance, tangible products containing software components and non-software components that are essential to the functionality of the tangible product will no longer be within the scope of the software revenue recognition guidance. This guidance is effective using the prospective application or the retrospective application for revenue arrangements entered into or materially modified in fiscal years beginning on or afte r June 15, 2010 with earlier application permitted. This guidance did not materially impact our results of operations or financial position.

In January 2010, the FASB issued authoritative guidance that amends the disclosure requirements related to recurring and nonrecurring fair value measurements. This guidance requires new disclosures on the transfers of assets and liabilities between Level 1 (assets and liabilities measured using observable inputs such as quoted prices in active markets) and Level 2 (assets and liabilities measured using inputs other than quoted prices in active markets that are either directly or indirectly observable) of the fair value measurement hierarchy, including the amount and reason of the transfers. Additionally, this guidance requires a roll forward of activities on purchases, sales, issuance, and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). This guidance is effect ive for interim and annual reporting periods beginning after December 15, 2009, with the exception of the additional disclosure for Level 3 assets and liabilities, which is effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. This guidance did not materially impact our results of operations or financial position, but did require changes to our disclosures in our interim and annual financial statements.

In February 2010, the FASB issued authoritative guidance that amends the disclosure requirements related to subsequent events. This guidance includes the definition of a Securities and Exchange Commission filer, removes the definition of a public entity, redefines the reissuance disclosure requirements and allows public companies to omit the disclosure of the date through which subsequent events have been evaluated.  This guidance is effective for financial statements issued for interim and annual periods ending after February 2010. This guidance did not materially impact our results of operations or financial position, but did require changes to our disclosures in our financial statements.

In April 2010, the FASB issued authoritative guidance related to the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate.  A vendor can recognize consideration that is contingent upon achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved if the milestone is: (a) commensurate with either the vendor’s performance to achieve the milestone or the enhancement of the value of the item delivered; (b) relates solely to past performance; and (c) is reasonable relative to all deliverables and payment terms in the arrangement.  This guidance is effective on a prospective basis for financial statements issued for interim and annual periods ending after June 15, 2010 with early adoption permitted.  The ado ption of this guidance 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, marketinganalytics and analyticmarketing 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, 2010,2013, revenue denominated in foreign currencies was approximately 8.4%4.6% of total revenue. For the year ended December 31, 2010,2013, our revenue would have decreased by approximately $1.9$2.0 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 currenc iescurrencies with which we have exposure at December 31, 20102013 would have resulted in an increase of approximately $900,000$3.6 million in the carrying amount of net assets. For the year ended December 31, 2010,2013, our revenue would have increased by approximately $1.9$2.0 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, 20102013 would have resulted in a decrease of approximately $900,000$3.6 million in the carrying amount of net assets. We currently do not use financial instruments to hedge our exposure to exchange rate fluctuations with respect to our foreign subsidiaries. We may seek to enter hedging transactions in the future to reduce our exposure to exchange rate fluctuations, but we may be unable to enter into hedging transactions successfully, on acceptable terms or at all. As of December 31, 2010,2013, accumulated other c omprehensivecomprehensive loss included a loss from foreign currency translation adjustments of approximately $5.9 million.$4.0 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, 2010.2013. As of December 31, 2010,2013, we had $210.1$256.0 million of cash and cash equivalents and short-term investments.equivalents. If there is an increase or decrease in interest rates, there will be a corresponding increase or decrease in the amount of interest earned on our cash and cash equivalents and short-term investments.equivalents. 

As of December 31, 2013, we had $153.1 million of long-term debt bearing interest at a variable rate of LIBOR plus 2.00%. If there is an increase or decrease in interest rates, there will be a corresponding increase or decrease in the amount of interest expense on our long-term debt. Based on our outstanding borrowings as of December 31, 2013, an increase in the interest rate by 25 basis points would result in an increase of approximately $400,000 in interest expense annually. Based on our outstanding borrowings as of December 31, 2013, a decrease in the interest rate by 25 basis points would result in a decrease of approximately $400,000 in interest expense annually. Based on our ability to access our cash and 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 ratedAAA-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, 2010,2013, auctions for $32.2$24.3 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, 2010,2013, we determined that there was a decline in the fair value of our ARS investments of approximately $3.0$1.5 million, which was deemed to be a temporary impairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. If the issuers are unable to successfully close future auctions andand/or their credit ratings deteriorate, we may be required to adjust the carrying value of these investments as a temporary impairment and recognize a greater unrealized loss in accumulated other comprehensive loss or as an other-than-temporary impairment charge to earnings. Based on our ability to access our cash and cash equivalents, and 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 2Notes 4 and 5 to the consolidated financial statementsNotes to Consolidated Financial Statements included in this Annual Report on Form 10-K for further discussion.

We have approximately $98.4$863.1 million in intangible assets as of December 31, 2010.2013. As of December 31, 2010,2013, we believe our intangible assets will be recoverable, however, changes in the economy, the business in which we operate and our own relative performance could change the assumptions used to evaluate intangible asset recoverability. In the event that we determine that an asset has been impaired, we would recognize an impairment charge equal to the amount by which the carrying amount of the assets exceeds the fair value of the asset. We continue to monitor these assumptions and their effect on the estimated recoverability of our intangible assets.

Item 9A.
Controls and Procedures

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

As of December 31, 2010,2013, 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.GAAP.


49



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

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

In connection with the preparation of the Company's annual financial statements, management of the Company has undertaken an assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 20102013 based on criteria established in Internal Control – Integrated Framework (1992 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, 2010.2013.

Ernst & Young LLP, the independent registered public accounting firm that audited the Company's financial statements included in this report, has issued an attestation report on the effectiveness of internal control over financial reporting, a copy of which is included in this Annual Report on Form 10-K.

There have been no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. as of December 31, 20102013 and 2009,2012, and the related consolidated statements of operations, stockholders’comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2010.2013. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These.These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CoStar Group, Inc. at December 31, 20102013 and 2009,2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2010,2013, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

Report of Independent Registered Public Accounting Firm

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

We have audited CoStar Group, Inc.’s internal control over financial reporting as of December 31, 2010,2013, based on criteria established in Internal Control—IntegratedControl-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). CoStar Group, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

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

In our opinion, CoStar Group, Inc.maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010,2013, based on the COSO criteria.criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CoStar Group, Inc. as of December 31, 20102013 and 2009,2012, and the related consolidated statements of operations, stockholders’comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2010 of CoStar Group, Inc.2013 and our report dated February 24, 201120, 2014 expressed an unqualified opinion thereon.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Reclassifications

Certain previously reported amounts in Note 9 and the Consolidated Statementsconsolidated statements of Cash Flowscash flows have been reclassified to conform to the Company’s current presentation.

Revenue Recognition

The Company primarily derives revenues by providing access to its proprietary database of commercial real estate information.

Subscription 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. Subscription-basedA majority of the subscription-based license agreements typically have a minimum term of one year and renew automatically.

Revenue is recognized when (1) there is persuasive evidence of an arrangement, (2) the fee is fixed and determinable, (3) services have been rendered and payment has been contractually earned and (4) collectability is reasonably assured.

Revenues, 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 (loss).

There were no material gains or losses from foreign currency exchange transactions for the years ended December 31, 2008, 20092011, 2012 and 2010.2013.

Income Taxes

Deferred income taxes result from temporary differences between the tax basis of assets and liabilities and the basis reported in the Company’s consolidated financial statements. Deferred tax liabilities and assets are determined based on the difference between the financial statement and the tax basis of assets and liabilities using enacted rates 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 an asset may not be realized through future taxable earnings or implementation of tax planning strategies. Interest and penalties related to income tax matters are recognized in income tax expense.

Net Income 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 potentially dilutive common shares would have an anti-dilutive effect.

Stock-Based Compensation (Continued)

Stock-based compensation costexpense is measured at the grant date of the share-basedstock-based awards that vest over set time periods based on their fair values, and is recognized on a straight line basis as expense over the vesting periods of the awards, net of an estimated forfeiture rate. For equity instruments that vest based on performance, the Company assesses the probability of the achievement of the performance conditions at the end of each reporting period, or more frequently based upon the occurrence of events that may change the probability of whether the performance conditions would be met. If the Company's initial estimates of the achievement of the performance conditions change, the related stock-based compensation expense and timing of recognition may fluctuate from period to period based on those estimates. If the performance conditions are not met, no stock-based compensation expense will be recognized and any previously recognized stock-based compensation expense will be reversed.

In 2012, the Company granted performance-based restricted common stock awards that vest upon the Company's achievement of $90.0 million of cumulative net income before interest, income taxes, depreciation and amortization ("EBITDA") over a period of four consecutive calendar quarters if such performance is achieved by March 31, 2017, subject to certain approvals under the CoStar Group, Inc. 2007 Stock Incentive Plan. As of March 31, 2013, the Company initially determined that it was probable that the performance condition for these performance-based restricted common stock awards would be met by the March 31, 2017 forfeiture date. As of December 31, 2013, the Company reassessed the probability of achieving this performance condition and determined that it was still probable that the performance condition for these awards would be met by the March 31, 2017 forfeiture date. As a result, the Company recorded a total of approximately $21.8 million of stock-based compensation expense related to performance-based restricted common stock for the year ended December 31, 2013. There was no stock-based compensation expense related to performance-based restricted common stock recorded for the years ended December 31, 2011 and December 31, 2012. The Company expects to record additional estimated unrecognized stock-based compensation expense related to performance-based restricted common stock of approximately $2.1 million in 2014.

Cash flows resulting from excess tax benefits are classified as part of net cash flows from operating and financing activities. Excess tax benefits represent tax benefits related to stock-based compensation in excess of the associated deferred tax asset for such equity compensation. Net cash proceeds from the exercise of stock options and ESPPthe purchase of shares under the Employee Stock Purchase Plan (“ESPP”) were approximately $6.9 million; $2.4$6.6 million, $9.9 million and $4.0$18.1 million for the years ended December 31, 2008, 20092011, 2012 and 2010,2013, respectively. There were approximately $5.3$2.5 million $403,000, $198,000 and $902,000$19.6 million of excess tax benefits realized from stock option exercisesoptions exercised and restricted stock awards vested for the years ended December 31, 2008, 20092011, 2012 and 2010.2013, respectively.

The large size and widespread nature of the Company’s customer base and the Company’s lack of dependence on any individual customers mitigatecustomer mitigates the risk of nonpayment of the Company’s accounts receivable.No single customer accounted for more than 5% of the Company’s revenues for each of the years ended December 31, 2011, 2012 and 2013. 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 and long-term debt approximates fair value.

Accounts Receivable, Net of Allowance for Doubtful Accounts

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

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:

Building
Thirty-nine years
Leasehold improvements Shorter of lease term or useful life
Furniture and office equipment Five to ten years
Research vehicles Five years
Computer hardware and software Two to five years

Qualifying internal-use software costs incurred during the application development stage, which consistconsists primarily of outside services, and purchased software license costs and internal product development 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.acquired businesses. 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. The Company’s operating segments, U.S. and International, are the reporting units tested for potential impairment. TheTo determine whether it is necessary to perform the two-step goodwill impairment test, the Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to assess qualitative factors, then the Company performs the two-step process. The first step is to determine the fair value of each reporting unit. The estimate of the fair value of each reporting unit is based on a projected discounted cash flow model that includes significant assumptions and estimates including the Company’sCompany's discount rate, growth rate and future financial performance andperformance. Assumptions about the discount rate are based on a weighted average cost of capital.capital for comparable companies. Assumptions about the growth rate and future financial performance of a reporting unit are based on the Company's forecasts, business plans, economic projections and anticipated future cash flows. The fa irfair 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 the Company’s management to be commensurate with the risk in its current business model.

To determine whether it is necessary to perform the quantitative impairment test for indefinite-lived intangible assets, the Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of the indefinite-lived intangible assets is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of the indefinite-lived intangible assets is less than the carrying amount or if the Company elects not to assess qualitative factors, then the Company performs the quantitative impairment test similar to the test performed on goodwill discussed above.

Intangible assets with estimable useful lives that arose from acquisitions on or after July 1, 2001 are amortized over their respective estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise used up, and are reviewed at least annually for impairment.

Long-Lived Assets

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 estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized byin the amount forby 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 disposeddisposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet.

Capitalized Product Development Costs

Product development costs are expensed as incurred until technological feasibility has been established, at which time such costs are capitalized. Costs are capitalized, to the extent that the capitalizable costs do not exceed the realizable value of such costs, until the product is available for general release to customers. The Company defines the establishment of technological feasibility as the completion of all planning, designing, coding and testing activities that are necessary to establish products that meet design specifications including functions, features and technical performance requirements. The Company’s capitalized product development costs had a total net book value of approximately $302,000 and $111,000 as of December 31, 2012 and 2013, respectively. These capitalized product development costs are included in intangible and other assets in the Company’s consolidated balance sheets. Amortization is computed using a straight-line method over the remaining estimated economic life of the product, typically three to five years after the software is ready for its intended use. The Company amortized capitalized product development costs of approximately $80,000, $191,000 and $191,000 for the years ended December 31, 2011, 2012 and 2013, respectively.

Debt Issuance Costs

Costs incurred in connection with the issuance of long-term debt are capitalized and amortized as interest expense over the term of the related debt using the effective interest method. The Company had capitalized debt issuance costs of approximately $9.6 million and $6.5 million as of December 31, 2012 and 2013, respectively. The debt issuance costs are associated with the financing commitment received from JPMorgan Chase Bank, N.A. (“J.P. Morgan Bank”) on April 27, 2011 and the subsequent term loan facility and revolving credit facility established under a credit agreement dated February 16, 2012 (the “Credit Agreement”). See Note 9 for additional information regarding the financing commitment with J.P. Morgan Bank and the Credit Agreement. No amortization expense for debt issuance costs was recognized by the Company for the year ended December 31, 2011. The Company amortized debt issuance costs of approximately $2.0 million and $3.0 million for the years ended December 31, 2012 and 2013, respectively.

Recent Accounting Pronouncements

In April 2008,July 2012, the Financial Accounting Standards Board (“FASB”("FASB") issued authoritative guidance on existing intangibles or expected future cash flows from those intangibles, whichto simplify how companies test indefinite-lived intangible assets for impairment. The guidance permits a company to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. This guidance is effective for allannual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. This guidance did not have a material impact on the Company's results of operations or financial position.

In February 2013, the FASB issued authoritative guidance to improve the reporting of reclassifications out of accumulated other comprehensive income. This guidance requires a company to present, either on the consolidated statements of operations or in the notes to the consolidated financial statements, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This guidance is effective prospectively for financial statements issued for interim and interimannual periods beginning after December 15, 2008. Early adoption of this guidance is not permitted.2012.

There are no accounting pronouncements that have been recently issued but not yet adopted by asset class, and the amount of renewal or extension costs capitalized, if any. For any intangibles acquired after December 31, 2008, this gui dance 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, this guidance 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 Company adopted this guidance on January 1, 2009. The adoption of this guidance did notwould have a material impact on the Company’s results of operations or financial position.

In June 2008, the FASB issued authoritative guidance related to determining whether instruments granted in share-based payment transactions are participating securities.  This guidance clarifies that unvested share-based payment awards with a right to receive non-forfeitable dividends are participating securities. This guidance is effective for all annual and interim periods beginning after December 15, 2008. Adoption of this standard will require the two-class method of calculating basic earnings per share to the extent that unvested share-based payments have the right to receive non-forfeitable dividends. The Company adopted this guidance on January 1, 2009.  The adoption of this guidance did not have a material impact on the Company’s results of operations or financial position.

In April 2009, the FASB issued authoritative guidance related to the initial recognition, measurement and subsequent accounting for assets and liabilities arising from pre-acquisition contingencies in a business combination. It requires that such assets acquired or liabilities assumed be initially recognized at fair value at the acquisition date if fair value can be determined during the measurement period. When fair value cannot be determined, companies should typically account for the acquired contingencies using existing guidance. This guidance requires that companies expense acquisition and deal-related costs that were previously allowed to be capitalized.  This guidance also requires that a systematic and rational basis for subsequently measuring and accounting for the assets or liabilities be developed depending on the ir nature. This guidance was effective for contingent assets or liabilities arising from business combinations with an acquisition date on or after January 1, 2009.   The adoption of this guidance changes the accounting treatment and disclosure for certain specific items in a business combination with an acquisition date subsequent to December 31, 2008.  The Company adopted this guidance on January 1, 2009, and expensed acquisition and deal-related costs of approximately $700,000 associated primarily with the acquisitions of Property and Portfolio Research, Inc. (“PPR”) and Resolve Technology, Inc. (“Resolve Technology”).

In April 2009, the FASB issued authoritative guidance for determining whether a market is active or inactive, and whether a transaction is distressed. This guidance is applicable to all assets and liabilities (financial and non-financial) and will require enhanced disclosures. The Company adopted this guidance for its interim period ending June 30, 2009. The adoption of this guidance did not have a material impact on the Company’s results of operations or financial position, but did require additional disclosures in the Company’s financial statements.

In April 2009, the FASB issued authoritative guidance requiring disclosures in interim reporting periods concerning the fair value of financial instruments that were previously only required in the annual financial statements. The Company adopted the provisions of this guidance for the interim period ending June 30, 2009. The adoption of this guidance did not have a material impact on the Company’s results of operations or financial position, but did require additional disclosures in the Company’s financial statements.

In April 2009, the FASB issued authoritative guidance that redefines what constitutes an other-than-temporary impairment, defines credit and non-credit components of an other-than-temporary impairment, prescribes their financial statement treatment, and requires enhanced disclosures relating to such impairments. The Company adopted this guidance for the interim period ending June 30, 2009. The adoption of this guidance did not have a material impact on the Company’s results of operations or financial position, but did require additional disclosures in the Company’s financial statements.

In May 2009, the FASB issued authoritative guidance which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. This guidance was effective for all interim and annual reporting periods ending after June 15, 2009. This guidance has not and is not expected to result in significant changes in the subsequent events that the Company reports, either through recognition or disclosure, in its financial statements.

In June 2009, the FASB issued authoritative guidance to amend the manner in which entities evaluate whether consolidation is required for variable interest entities (VIE).  Previously, variable interest holders were required to determine whether they had a controlling financial interest in a VIE based on a quantitative analysis of the expected gains and/or losses of the entity.  The new guidance requires an enterprise with a variable interest in a VIE to qualitatively assess whether it has a controlling financial interest in the entity, and if so, whether it is the primary beneficiary.  This guidance also requires that companies continually evaluate VIEs for consolidation, rather than assessing whether consolidation is required based upon the occurrence of triggering events.  This guidance enhan ces disclosures to provide financial statement users with greater transparency about transfers of financial assets and a transferor’s continuing involvement with transferred financial assets. This guidance will be effective for the first annual reporting period beginning after November 15, 2009. This guidance did not materially impact the Company’s results of operations, financial position or related disclosures.

In June 2009, the FASB issued authoritative guidance which replaced the previous hierarchy of U.S. GAAP and establishes the FASB Codification as the single source of authoritative U.S. GAAP recognized by the FASB to be applied by nongovernmental entities. This guidance is effective for financial statements issued for interim and annual periods ending after September 15, 2009. This guidance did not materially impact the Company’s results of operations or financial position, but did require changes to the disclosures in the Company’s financial statements.

In July 2009, the FASB issued authoritative guidance to improve the consistency with which companies apply fair value measurements guidance to liabilities.  This guidance is effective for interim and annual periods beginning after September 30, 2009.  This guidance did not materially impact the Company’s results of operations, financial position or related disclosures.

In October 2009, the FASB issued authoritative guidance that amends existing guidance for identifying separate deliverables in a revenue-generating transaction where multiple deliverables exist, and provides guidance for measuring and allocating revenue to one or more units of accounting.  In addition, the FASB issued authoritative guidance on arrangements that include software elements.  Under this guidance, tangible products containing software components and non-software components that are essential to the functionality of the tangible product will no longer be within the scope of the software revenue recognition guidance. This guidance is effective using the prospective application or the retrospective application for revenue arrangements entered into or materially modified in fiscal years beginning on or afte r June 15, 2010 with earlier application permitted. This guidance did not materially impact the Company’s results of operations or financial position.

In January 2010, the FASB issued authoritative guidance that amends the disclosure requirements related to recurring and nonrecurring fair value measurements. This guidance requires new disclosures on the transfers of assets and liabilities between Level 1 (assets and liabilities measured using observable inputs such as quoted prices in active markets) and Level 2 (assets and liabilities measured using inputs other than quoted prices in active markets that are either directly or indirectly observable) of the fair value measurement hierarchy, including the amount and reason of the transfers. Additionally, this guidance requires a roll forward of activities on purchases, sales, issuance, and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). This guidance is effect ive for interim and annual reporting periods beginning after December 15, 2009, with the exception of the additional disclosure for Level 3 assets and liabilities, which is effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. This guidance did not materially impact the Company’s results of operations or financial position, but did require changes to the disclosures in its interim and annual financial statements.

In February 2010, the FASB issued authoritative guidance that amends the disclosure requirements related to subsequent events. This guidance includes the definition of a Securities and Exchange Commission filer, removes the definition of a public entity, redefines the reissuance disclosure requirements and allows public companies to omit the disclosure of the date through which subsequent events have been evaluated.  This guidance is effective for financial statements issued for interim and annual periods ending after February 2010. This guidance did not materially impact the Company’s results of operations or financial position, but did require changes to the Company’s disclosures in its financial statements.

In April 2010, the FASB issued authoritative guidance related to the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate.  A vendor can recognize consideration that is contingent upon achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved if the milestone is: (a) commensurate with either the vendor’s performance to achieve the milestone or the enhancement of the value of the item delivered; (b) relates solely to past performance; and (c) is reasonable relative to all deliverables and payment terms in the arrangement.  This guidance is effective on a prospective basis for financial statements issued for interim and annual periods ending after June 15, 2010 with early adoption permitted.  The ado ption of this guidance did not have a material impact on the Company’s results of operations or financial position.

UnrealizedChanges in unrealized holding gains and losses, net of the related tax effect, on available-for-sale securities are excluded from earnings and are reported as a separate component of accumulated other comprehensive income (loss) 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, 20092012 and 20102013 were generated primarily from changes 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 does not intend to sell these instruments and it is more likely than not that the Company will not be required to sell these instruments prior to anticipated recovery, which may be at maturity, itthe Company does not consider these investments to be other-than-temporarily impaired as of December 31, 20092012 and 2010.2013. See Note 5 to the consolidated financial statements for further discussion onof the fair value of the Company’s financial assets.

5.FAIR VALUE

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

ARS are variable rate debt instruments whose interest rates are reset approximately every 28 days.days. The majority of the underlying securities have contractual maturities greater than twenty years.years. The ARS are recorded at fair value.

As of December 31, 2010,2013, the Company held ARS with $32.2$24.3 million par value, all of which failed to settle at auction. The majority of these investments are of high credit quality with AAA credit ratings and are primarily student loan securities supported by guarantees from the FFELP of the U.S. Department of Education. The Company may not be able to liquidate and fully recover the carrying value of the ARS in the near term. As a result, these securities are classified as long-term investments in the Company’s consolidated balance sheet as of December 31, 2010. 2013

While the Company continues to earn interest on its ARS investments at the contractual rate, these investments are not currently actively trading and therefore do not currently have a readily determinable market value. Accordingly, theThe 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, 2010.2013. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, credit spreads, timing and amount of contractual cash flows, liquidity risk premiums, expected holding periods and default risk. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the assumptions used in the model and settlements of ARS investments that occurred during the period.
The only significant unobservable input in the discounted cash flow model is the discount rate. The discount rate used represents the Company's estimate of the yield expected by a market participant from the ARS investments. The weighted average discount rate used in the discounted cash flow model as of December 31, 2012 and 2013 was approximately 5.1% and 4.9%, respectively. Selecting another discount rate within the range used in the discounted cash flow model would not result in a significant change to the fair value of the ARS.

FAIR VALUE (CONTINUED)

Based on this assessment of fair value, as of December 31, 2010,2013, the Company determined there was a decline in the fair value of its ARS investments of approximately $3.0 million.$1.5 million. The decline was deemed to be a temporary impairment and recorded as an unrealized loss in accumulated other comprehensive loss in stockholders’ equity. In addition, while a majority of the ARS are currently rated AAA, if the issuers are unable to successfully close future auctions and/or their credit ratings deteriorate, the Company may be required to record additional unrealized losses in accumulated other comprehensive loss or an other-than-temporary impairment charge to earnings on these investments.

("Reaction Web") on March 31, 2014 based on Reaction Web's achievement of revenue milestones, resulting in undiscounted deferred consideration as of December 31, 2013 of approximately $344,000. On March 28, 2013, the Company made a payment of $1.0 million to the sellers of LandsofAmerica based on the achievement of financial and operational milestones in 2012 and a payment of approximately $344,000 to the sellers of Reaction Web based on the achievement of revenue milestones in 2012.

As of December 31, 2010, the Company’s Level 3 liabilities consist of a $3.2 million liability for deferred consideration related to the October 19, 2009 acquisition of Resolve Technology. The deferred consideration includes (i) a potential deferred cash payment due approximately two years after closing based on the incremental growth of Resolve Technology’s revenue as of September 2011 over its revenue as of September 2009, and (ii) other potential deferred cash payments for successful completion of operational and sales milestones during the period from closing through no later than October 31, 2013, which period may be extended by the parties to a date no later than December 31, 2014.

6. PROPERTY AND EQUIPMENTThe only significant unobservable input in the discounted cash flow model used to determine the estimated fair value of the Company's Level 3 liabilities is the discount rate. The discount rate used represents LoopNet's cost of equity at the time of each acquisition plus a margin for counterparty risk. The weighted average discount rate used as of December 31, 2012 was approximately 23.5%. As of December 31, 2013, the Company recorded a liability for the entire amount of undiscounted deferred consideration to be paid on March 31, 2014. Selecting another discount rate within the range used in the discounted cash flow model in 2012 would not result in a significant change to the fair value of the deferred consideration.

9.LONG-TERM DEBT 

On February 16, 2012, the Company entered into a term loan facility and revolving credit facility pursuant to the Credit Agreement dated February 16, 2012, by and among the Company, as borrower, CoStar Realty Information, Inc. ("CoStar Realty"), as co-borrower, J.P. Morgan Bank, as administrative agent, and the other lenders thereto. The Credit Agreement provides for a $175.0 million term loan facility and a $50.0 million revolving credit facility, each with a term of five years. On April 30, 2012, the Company borrowed $175.0 million under the term loan facility and used those proceeds, together with net proceeds from the Company's equity offering conducted in June 2011, to pay a portion of the merger consideration and transaction costs related to the LoopNet merger. The carrying value of the term loan facility approximates fair value and can be estimated through Level 3 unobservable inputs using an expected present value technique based on expected cash flows discounted using the current credit-adjusted risk-free rate, which approximates the rate of interest on the term loan facility at the origination.

The revolving credit facility includes a subfacility for swingline loans of up to $5.0 million and up to $10.0 million of the revolving credit facility is available for the issuances of letters of credit. The term loan facility amortizes in quarterly installments in amounts resulting in an annual amortization of 5% during the first year, 10% during the second year, 15% during the third year, 20% during the fourth year and 50% during the fifth year after the closing date. The loans under the Credit Agreement bear interest, at the Company's option, either (i) during any interest period selected by the Company, at the London interbank offered rate for deposits in U.S. dollars with a maturity comparable to such interest period, adjusted for statutory reserves (“LIBOR”), plus a spread of 2.00% per annum, or (ii) at the greatest of (x) the prime rate from time to time announced by J.P. Morgan Bank, (y) the federal funds effective rate plus ½ of 1.00% and (z) LIBOR for a one-month interest period plus 1.00%, plus a spread of 1.00% per annum. If an event of default occurs under the Credit Agreement, the interest rate on overdue amounts will increase by 2.00% per annum. The obligations under the Credit Agreement are guaranteed by all material subsidiaries of the Company and secured by a lien on substantially all of the assets of the Company and its material subsidiaries, in each case subject to certain exceptions.

The Credit Agreement requires the Company to maintain a Debt Service Coverage Ratio (as defined in the Credit Agreement) of at least 1.5 to 1.0 and a Total Leverage Ratio (as defined in the Credit Agreement) that does not exceed 2.75 to 1.00 during each of the three months ending December 31, 2013, March 31, 2014 and June 30, 2014; and 2.50 to 1.00 thereafter. The Credit Agreement also includes other covenants that were effective as of April 30, 2012, including covenants that, subject to certain exceptions, restrict the ability of the Company and its subsidiaries (i) to incur additional indebtedness, (ii) to create, incur, assume or permit to exist any liens, (iii) to enter into mergers, consolidations or similar transactions, (iv) to make investments and acquisitions, (v) to make certain dispositions of assets, (vi) to make dividends, distributions and prepayments of certain indebtedness, and (vii) to enter into certain transactions with affiliates. The Company was in compliance with the covenants in the Credit Agreement as of December 31, 2013.
  
Commencing with the fiscal year ended December 31, 2012, the Credit Agreement requires the Company to make an annual prepayment of the term loan facility equal to a percentage of Excess Cash Flow (as defined in the Credit Agreement) to reduce the principal amount outstanding under the term loan facility. The prepayment percentage is 50% when the Total Leverage Ratio exceeds 3.00 to 1.00; 25% when the Total Leverage Ratio is greater than 2.50 to 1.00 but equal to or less than 3.00 to 1.00; and 0% when the Total Leverage Ratio is equal to or less than 2.50 to 1.00. This prepayment requirement is reduced by the amount of prior voluntary prepayments during the respective fiscal year, subject to certain exceptions set forth in the Credit Agreement. The Excess Cash Flow payment, if required, is due within ten business days of the date on which the annual financial statements are delivered or required to be delivered to the lenders pursuant to the Credit Agreement. For the fiscal year ended December 31, 2013, the Company was not required to make an Excess Cash Flow payment.
9. INCOME TAXES
In connection with obtaining the term loan facility and revolving credit facility, the Company incurred approximately $11.5 million in debt issuance costs, which were capitalized and are being amortized as interest expense over the term of the Credit Agreement using the effective interest method. The debt issuance costs are comprised of approximately $9.2 million in underwriting fees and approximately $2.3 million primarily related to legal fees associated with the debt issuance. 

As of December 31, 2012 and 2013, no amounts were outstanding under the revolving credit facility.

For the years ended December 31, 20092012 and 2010,2013, a valuation allowance has been established for certain deferred tax assets due to the uncertainty of realization. The valuation allowance for the years ended as of December 31, 20092012 and 20102013 includes an allowance for unrealized losses capital loss carryforwards,on ARS investments, foreign deferred tax assets and certain state net operating loss carryforwards. The valuation allowance for the deferred tax asset for unrealized losses on ARS has been recorded as an adjustment to accumulated other comprehensive loss.

The Company established the valuation allowance because it is more likely than not that a portion of the deferred tax asset for certain items will not be realized based on the weight of available evidence. A valuation allowance was established for the unrealized losses on securities and the capital loss carryovers as the Company has not historically generated capital gains, and it is uncertain whether the Company will generate sufficient capital gains in the future to absorb the capital losses. In 2011, the Company sold the office building located at 1331 L Street, NW, in downtown Washington, DC (the “DC Office Building") and the sale generated capital gains, but the Company does not expect to engage in similar transactions on a regular basis. The Company continues to maintain a valuation allowance as of December 31, 2013, for the unrealized losses on securities because it is uncertain as to whether the losses will be realized in a year such that the losses could be carried back to offset the gain from the Company’s sale of the DC Office Building. A valuation allowance was established for the foreign deferred tax assets due to the uncertainty of future foreign taxable income.cumulative loss in recent years in those jurisdictions. The Company has not had sufficient taxable income historically to utilize the foreign deferred tax assets, and it is uncertain whether the Company will generate sufficient taxable income in the future.  Si milarly,future to utilize the deferred tax assets. Similarly, the Company has established a valuation allowance for net operating losses in certain states where it is uncertain whether the Company will generate sufficient taxable income to utilize the net operating losses before the lossesthey expire.

The Company’s change in valuation allowance was a decreasean increase of approximately $62,000$5.2 million for the year ended December 31, 20092012 and an increase of approximately $1.7 million$446,000 for the year ended December 31, 2010.2013. The increase for the year ended December 31, 20102013 is primarily due to the increase in the valuation allowance for foreign deferred tax assets.assets of approximately $765,000 partially offset by a decrease in the valuation allowance for deferred tax assets of approximately $319,000 primarily related to state net operating loss carryforwards.

In May 2011, LoopNet, the Board of Directors of LoopNet (“the LoopNet Board”) and/or the Company were named as defendants in three purported class action lawsuits brought by alleged LoopNet stockholders challenging LoopNet's proposed merger with the Company. The stockholder actions alleged, among other things, that (i) each member of the LoopNet Board breached his fiduciary duties to LoopNet and its stockholders in authorizing the sale of LoopNet to the Company, (ii) the merger did not maximize value to LoopNet stockholders, (iii) LoopNet and the Company made incomplete or materially misleading disclosures about the transaction and (iv) LoopNet and the Company aided and abetted the breaches of fiduciary duty allegedly committed by the members of the LoopNet Board. The stockholder actions sought class action certification and equitable relief, including an injunction against consummation of the merger. The parties stipulated to the consolidation of the actions, and to permit the filing of a consolidated complaint. In June 2011, counsel for the parties entered into a memorandum of understanding in which they agreed on the terms of a settlement of this litigation, which could result in a loss to the Company of approximately $200,000. On March 20, 2013, the California Superior Court declined to grant preliminary approval to the proposed settlement and issued an order scheduling a hearing on June 11, 2013 to show good cause why the case should not be dismissed. Shortly before the hearing plaintiffs filed a third supplemental submission in support of their motion for preliminary approval of the proposed settlement, and the Court rescheduled the show cause hearing for February 11, 2014, and then rescheduled it again for May 13, 2014.

On December 8, 2009, a former employee filed a lawsuit againstJanuary 3, 2012, LoopNet, the CompanyCompany’s wholly owned subsidiary, was sued by CIVIX-DDI, LLC (“Civix”) in the United StatesU.S. District Court for the SouthernEastern District of California alleging violationsVirginia for alleged infringement of U.S. Patent Nos. 6,385,622 and 6,415,291. The complaint seeks unspecified damages, attorneys' fees and costs. On February 16, 2012, LoopNet filed an answer to Civix’s complaint and filed counterclaims against Civix seeking, among other things, declaratory relief that the asserted patents are invalid, not infringed, and that Civix committed inequitable conduct during the prosecution and re-examination of the Fair Labor Standards Actasserted patents. On or about May 14, 2012, Civix filed a motion for leave to amend its complaint against LoopNet in the U.S. District Court for the Eastern District of Virginia seeking to add the Company as a defendant, alleging that the Company's products also infringe Civix's patents. The Company filed a motion opposing Civix's motion, and California state wage-and-hour lawson June 21, 2012, the district court denied Civix's motion to amend its complaint. On June 21, 2012, the Company filed an action in the U.S. District Court for the Northern District of Illinois seeking a declaratory judgment of non-infringement and invalidity against Civix. On August 14, 2012, the Company amended its complaint against Civix to assert an affirmative claim against Civix for breach of contract, alleging Civix viloated its license agreement and covenant not to sue with one of the Company's technology licensors. On August 30, 2012, the Eastern District of Virginia transferred Civix's case against LoopNet to the Northern District of Illinois, where both cases are now pending. On October 29, 2012, Civix filed a separate action against LoopNet in the Northern District of Illinois alleging infringement of U.S. Patent No. 8,296,335. That case was later consolidated with Civix's original lawsuit against LoopNet. Civix amended its complaint against the Company on November 8, 2012 to add claims under Patent No. 8,296,335 as well. On November 15, 2012, LoopNet filed an amended answer and counterclaim against Civix, asserting an affirmative claim against Civix for breach of contract, alleging Civix violated its license agreement and covenant not to sue with one of LoopNet's technology licensors. The U.S. District Court for the Northern District of Illinois construed the language of the patent on September 23, 2013, and has issued a schedule providing for expert discovery and dispositive motions in this case through April 2014, but no trial date has been set.

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 for new awards under the 1998 Plan. The 1998 Plan continues to govern unexercised and unexpired awar dsawards issued under the 1998 Plan prior to June 7, 2007. The 1998 Plan provided for the grant of stock and stock options to officers, directors and employees of the Company and its subsidiaries. Stock options granted under the 1998 Plan could be incentive or non-qualified. Thenon-qualified, and the exercise price for an incentive stock option may not be less than the fair market value of the Company’s common stock on the date of grant. The vesting period of the options and restricted stock grants under the 1998 Plan was determined by the Board of Directors or a committee thereof and was generally three to four years.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 or a committee thereof and is generally three to four years, subject to minimum vesting periods for restricted stock and restricted stock units of at lea st least one year.year. In some cases, vesting of awards under the 2007 Plan may be based on performance conditions. The Company has issued and/or reserved the following shares of common stock for issuance under the 2007 Plan (including an increase of 1,300,000 shares of common stock pursuant to an amendment to the 2007 Plan approved by the StockholdersCompany’s stockholders on June 2, 2010)2010 and an increase of 900,000 shares of common stock pursuant to an amendment to the 2007 Plan approved by the Company’s stockholders on June 5, 2012): (a) 2,300,0003,200,000 shares of common stock, plus (b) 121,875 shares of common stock that were authorized for issuance under the 1998 Plan that, as of June 7, 2007, remained available for issuance under the 1998 Plan (not including any Shares that were subject as of such date to outstanding awards under the 1998 Plan), and (c) any shares of common stock subject to outstanding awards under the 1998 Plan as of June 7, 2007, that on or after such date cease for any reason to be subject to such awards (other than by reason of exercise or settlement of the awards to the extent they are exercised for or settled in vested and nonforfeitable shares). Unless terminated sooner, the 2007 Plan will terminate in April 2017, but will continue to govern unexercised and unexpired awards issued under the 2007 Plan prior to that date. Approximately 430,0001.4 million and 1.91.2 million shares were available for future grant under the 2007 Plan as of December 31, 20092012 and 2010,2013, respectively.

In February 2012, the Compensation Committee (the “Committee”) of the Board of Directors of the Company approved grants of restricted common stock to the executive officers that vest based on the achievement of Company performance conditions. These awards support the Committee’s goals of aligning executive incentives with long-term stockholder value and ensuring that executive officers have a continuing stake in the long-term success of the Company. In May and December of 2012, the Company granted additional shares of restricted common stock that vest based on the achievement of the Company's performance conditions to other employees. These shares of performance-based restricted common stock vest upon the Company’s achievement of $90.0 million of cumulative EBITDA over a period of four consecutive calendar quarters, and are subject to forfeiture in the event the foregoing performance condition is not met by March 31, 2017. The Company granted a total of 399,413 shares of performance-based restricted common stock during the year ended December 31, 2012. There were no shares of performance-based restricted common stock granted by the Company during the year ended December 31, 2013. All of the awards were made under the 2007 Plan and pursuant to the Company’s standard form of restricted stock grant agreement. The number of shares granted was based on the fair market value of the Company’s common stock on the grant date. As of March 31, 2013, the Company initially determined that it was probable that the performance condition for these performance-based restricted common stock awards would be met by the March 31, 2017 forfeiture date. As of December 31, 2013, the Company reassessed the probability of achieving this performance condition and determined that it was still probable that the performance condition for these awards would be met by the March 31, 2017 forfeiture date, subject to certain approvals under the 2007 Plan. As a result, the Company recorded a total of approximately $21.8 million of stock-based compensation expense related to performance-based restricted common stock for the year ended December 31, 2013. There was no stock-based compensation expense related to performance-based restricted common stock recorded for the years ended December 31, 2011 and 2012.
