Dear Stockholder:

You are cordially invited to attend the 2014 Annual Meeting of Stockholders of CoStar Group, Inc., to be held at 10:00 a.m., local time, on Monday, June 2, 2014 at 1331 L Street N.W., Washington, DC 20005.

At the Annual Meeting, you will be asked (1) to elect the eight directors named in the Proxy Statement, (2) to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for 2014, and (3) to approve, on an advisory basis, CoStar Group, Inc.’s executive compensation. The accompanying Notice of 2014 Annual Meeting of Stockholders and Proxy Statement describe these matters.

The Board of Directors recommends that stockholders vote in favor of each of the director nominees and the other proposals.

Important Notice Regarding the Availability of Proxy Materials

for the 2014 Annual Meeting of Stockholders:

We are mailing many of our stockholders a Notice of Internet Availability of Proxy Materials rather than a full set of our proxy materials. The Notice contains instructions on how to access our proxy materials on the Internet, as well as instructions on how to obtain a paper copy of the full set of proxy materials if a stockholder so desires. This process is more environmentally friendly and may reduce our costs to print and distribute these materials to stockholders. All stockholders who do not receive this Notice of Availability, including stockholders who have previously requested to receive a paper copy of the materials, will receive a full set of our proxy materials by mail.

In order to ensure your representation at the Annual Meeting, whether or not you plan to attend the meeting, please vote your shares as promptly as possible over the Internet by following the instructions on your Notice or, if you receive a complete set of proxy materials by U.S. mail, by following the instructions on your proxy card. Your participation will help to ensure the presence of a quorum at the meeting and save CoStar the extra expense associated with additional solicitation. Voting your shares over the Internet or otherwise will not prevent you from attending the meeting, revoking your proxy, or voting your stock in person.

Sincerely,

ANDREW C. FLORANCE

Chief Executive Officer and President

PROXY STATEMENT

ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON MONDAY, JUNE 2, 2014

The Board of Directors (the “Board”) of CoStar Group, Inc. (“CoStar”, “we” or the “Company”) solicits your proxy for use at the Annual Meeting of Stockholders (the “Annual Meeting”) to be held at 10:00 a.m., local time, on Monday, June 2, 2014, at the Company’s principal executive offices at 1331 L Street N.W., Washington, DC 20005, and at any adjournment or postponement of the Annual Meeting.

We are mailing the Notice Regarding the Availability of Proxy Materials to our stockholders eligible to vote at the Annual Meeting on or about April 22, 2014.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE STOCKHOLDER MEETING TO BE HELD ON JUNE 2, 2014

The Notice of Meeting and this Proxy Statement are available on our corporate website at www.CoStar.com/Investors/SECFilings.aspx and our 2013 Annual Report to stockholders is available on our corporate website at www.CoStar.com/Investors/Reports.aspx.

OUTSTANDING SECURITIES, VOTING RIGHTS AND QUORUM

At the close of business on the record date, Friday, April 4, 2014, there were 28,702,079 shares of common stock outstanding and entitled to vote at the Annual Meeting. Each outstanding share of common stock is entitled to one vote on each of the eight director nominees and on each of the other proposals.

The presence at the Annual Meeting, in person or by proxy, of a majority of the outstanding shares as of the record date constitutes a quorum (the minimum number of shares required to take action) for the Annual Meeting. Both abstentions and broker non-votes will be counted as shares present for purposes of obtaining a quorum.

The required vote and the calculation method for each of the matters scheduled for consideration at the Annual Meeting are as follows:

Election of Directors. Our Bylaws provide that, in an uncontested election, each director will be elected by a majority of votes cast. A “majority of votes cast” means the number of shares voted “FOR” a director exceeds the number of shares voted “AGAINST” that director. Our Board of Directors has adopted a director resignation policy consistent with the majority voting standard in our Bylaws. The policy provides that an incumbent director who does not receive the requisite majority of the votes cast for his or her election shall tender his or her resignation to the Board of Directors. The Nominating & Corporate Governance Committee will then recommend to the Board, and the Board will decide, whether to accept or reject the resignation offer or take other action. In making its decision, the Board may consider any factors or information that it considers relevant. The Board will act on the recommendation of the Nominating & Corporate Governance Committee within 90 days following certification of the election results.

The majority voting standard does not apply, however, in a contested election, as further described in our Bylaws. The election of directors at the 2014 annual meeting will not be contested and each of the directors will be elected by a majority of votes cast.

Each of the Other Proposals. Approval of each of the other proposals to be voted on at the Annual Meeting requires a majority of votes cast, which means that the number of shares voted “FOR” the proposal must exceed the number of shares voted “AGAINST” the proposal.

Treatment of Abstentions

With respect to the election of directors and the other proposals, stockholders may vote or abstain from voting. Abstentions will not affect the outcome of the election of directors or the other proposals because they are disregarded in calculating the total number of votes cast. Abstentions will be counted as present and entitled to vote for purposes of determining the presence of a quorum at the Annual Meeting.

Treatment of Broker Non-Votes

If your shares are held in street name through a broker, bank or other nominee, you are considered the beneficial owner of shares held in street name. As the beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote your shares. Your broker, bank or other nominee has the discretion to vote on routine corporate matters (routine matters include ratification of the appointment of the Company’s independent registered public accounting firm) presented in the proxy materials without your specific voting instructions. For non-routine matters (non-routine matters include election of directors and approval of the advisory resolution on executive compensation), your shares will not be voted without your specific voting instructions, resulting in a “broker non-vote.”

Broker non-votes will not affect the outcome of the election of directors or the other proposals because they are disregarded in calculating the total number of votes cast on the election of directors and each of the other proposals. Broker non-votes will be counted as present and entitled to vote for purposes of determining the presence of a quorum at the Annual Meeting.

PROXY VOTING AND REVOCATION

There are four ways you can vote:


1.	By Internet (www.proxyvote.com): You may vote over the Internet by following the instructions provided in the Notice or, if you receive a complete set of proxy materials by U.S. mail, by following the instructions on the proxy card.


2.	By Telephone: If you receive a complete set of proxy materials by U.S. mail, you may vote by telephone by following the instructions on your proxy card.


3.	By Mail: If you receive a complete set of proxy materials by U.S. mail, you may complete, sign and return the accompanying proxy card in the postage-paid envelope provided or return it to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.


4.	In Person: If you are a stockholder as of the Record Date, you may vote in person at the Annual Meeting. Submitting a proxy will not prevent a stockholder from attending the Annual Meeting, revoking their earlier-submitted proxy or voting in person.

If you properly complete and execute your proxy card in one of the ways set forth above:


•	Your shares will be voted in accordance with your instructions.

•

If you sign, date and return the proxy card and there are any items for which you do not provide instructions, your shares will be voted in accordance with the Board’s recommendations as follows: “FOR” election of each of the director nominees, “FOR” approval of the proposal to remove the voting standard from the Company’s Restated Certificate of Incorporation so that the Board of Directors may provide for majority voting in uncontested director elections, “FOR” ratification of the independent registered public accounting firm, and “FOR” approval of the advisory resolution on executive compensation.

You may revoke your proxy at any time before it is voted by:


•	delivering to the Corporate Secretary written notice that you are revoking your proxy;


•	submitting a properly executed proxy bearing a later date; or


•	attending the Annual Meeting and voting in person. If you are not the owner of record, but rather hold your shares through a broker or bank, you should take appropriate steps to obtain a legal proxy from the owner of record if you wish to attend and vote at the Annual Meeting.

Simply attending the Annual Meeting will not revoke your proxy. If you instructed a broker to vote your shares, you must follow your broker’s directions for changing those instructions.

ATTENDING THE ANNUAL MEETING

Only stockholders as of the record date, their proxy holders and our invited guests may attend the Annual Meeting. Beneficial owners whose ownership is registered under another party’s name and who plan to attend the Annual Meeting in person should obtain an admission ticket in advance by sending written requests, along with proof of beneficial ownership, such as a bank or brokerage firm account statement, to: Rich Simonelli, Senior Director of Investor Relations, CoStar Group, Inc., 1331 L Street N.W., Washington, DC 20005. Beneficial owners who do not present valid admission tickets at the registration counter at the Annual Meeting will be admitted at CoStar’s sole discretion and may be required to verify share ownership, which may be established by providing a bank or brokerage firm account statement and photo identification, at the registration counter at the Annual Meeting. Stockholders as of the record date or their proxy holders who plan to attend the Annual Meeting may also be asked to present photo identification at the registration counter at the Annual Meeting to gain admittance to the Annual Meeting.

ITEM 1

ELECTION OF DIRECTORS

The Board has currently fixed the number of directors constituting the Board at eight. The Nominating & Corporate Governance Committee has recommended and the Board has nominated the eight current directors for reelection, all of whom were last elected at the 2013 Annual Meeting of Stockholders. The persons named as proxy holders on the proxy card will vote your shares “FOR” each of the eight nominees unless you instruct otherwise on your proxy card.

Each of our directors elected at the Annual Meeting will serve until the next Annual Meeting of Stockholders or until his successor is elected and qualified. We know of no reason why any nominee would be unable to serve. However, if any of the nominees should become unable to serve prior to the Annual Meeting, proxies that do not withhold authority to vote for directors may be voted for any other nominee or nominees selected by the Board unless the Board votes to reduce the size of the Board to match the actual number of nominees. In no event may proxies be voted for a greater number of persons than the number of nominees named. We did not receive any stockholder nominations for director in connection with the 2014 Annual Meeting.

BOARD COMPOSITION

Our Nominating & Corporate Governance Committee is responsible for reviewing and assessing with the Board the Board’s membership criteria. The criteria include independence; judgment; integrity; ability to commit sufficient time and attention to the activities of the Board; an individual's business experience, skills and background, including an understanding of and experience with commercial real estate, information services, and technology industries; finance and marketing expertise; and absence of potential conflicts with the Company’s interests. The Nominating & Corporate Governance Committee seeks a diversity of occupational and personal backgrounds on the Board in order to obtain a range of viewpoints and perspectives. In addition, the Nominating & Corporate Governance Committee evaluates the composition of the Board to assess the skills and experience that are currently represented on the Board, as well as the skills and experience that the Board will find valuable in the future, given the Company’s current situation and strategic plans. This evaluation enables the Nominating & Corporate Governance Committee to assess its effectiveness at achieving these Board membership objectives.

We do not expect or intend that each director will have the same skills, experience and background. We expect that our Board members will have a diverse portfolio of skills, experiences and backgrounds and that each will contribute to the composition of the Board so that collectively the Board will possess the necessary skills, experience and background to oversee the business and affairs of the Company. Below is a list of key skills and experience that our directors bring to our Board that we consider important in light of our current business and structure. The directors’ individual biographies below describe each director’s most relevant experience, qualifications and skills.


•	Industry Expertise. We seek directors with experience in the commercial real estate, data provider and technology industries. Experience in those areas is valuable in understanding our growth and development efforts, as well as the market segments in which we operate.


•	Financial Expertise. We believe that an understanding of accounting and financial reporting processes is important because it assists our directors in understanding, advising and overseeing our investing activities, financial reporting and internal controls. We measure our operating performance by reference to financial targets. We expect all of our directors to be financially knowledgeable.

•

Mergers & Acquisitions Experience. We have grown over the years in part through mergers & acquisitions activity and believe directors who have a background in mergers & acquisitions transactions can provide insight into developing and implementing strategies for growing our operations through business combinations and also provide relevant input regarding our business strategy. Relevant experience in this area includes experience identifying and valuing proposed transactions, analyzing the ‘fit’ of a proposed acquisition target with the Company’s strategy, and integrating acquired companies with our existing operations.


•	Business Development. We expect to grow organically by identifying and developing new services and new markets for our services. Directors who have expertise in business development can provide insight into developing and implementing strategies for growing our business organically.

•

Public Company Board and Management Experience. Directors who have served on other public company boards and/or as executives of other public companies can offer advice and insight with regard to the dynamics and operation of a board of directors, the relationship between a board and the CEO and other management personnel, and an understanding of good corporate governance practices and risk management.


•	Leadership Experience. Directors who have served in a leadership capacity or as executives at other companies provide valuable operational insight and can help the Board operate efficiently and effectively.

ITEM 2

RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has recommended and the Board has approved the appointment of Ernst & Young LLP as the independent registered public accounting firm for the Company for 2014. As a matter of good corporate governance, the Board is asking stockholders to ratify this appointment, even though ratification is not required. If stockholders do not ratify this appointment, the Board may, but is not required to, reconsider such appointment. Even if stockholders ratify this appointment, the Board may direct the appointment of a different independent auditor at any time during 2014 if, in its discretion, it determines that such a change would be in the Company’s best interests.

Ernst & Young LLP has served as the independent registered public accounting firm for the Company, its subsidiaries, and its predecessors since 1994. A representative from Ernst & Young LLP is expected to attend the Annual Meeting, will have the opportunity to make a statement if he or she desires to do so and is expected to be available to respond to appropriate questions.

For the years ended December 31, 2012 and 2013, Ernst & Young LLP billed CoStar the fees set forth below, including expenses, in connection with services rendered to CoStar:



	Year Ended December 31, 2012		Year Ended December 31, 2013
Audit Fees	$	1,427,358	$	1,180,810
Audit Related Fees	21,883		61,681
Tax Fees	40,000		34,000
All Other Fees	—		—
Total	$	1,489,241	$	1,276,491

Audit Fees include fees for services performed for the audit of CoStar’s annual financial statements, review of financial statements included in CoStar’s periodic filings with the SEC, audit of CoStar’s internal control over financial reporting and statutory audits required internationally. Included in the services performed for the audit of CoStar’s 2012 annual financial statements is $233,000 related to the acquisition of LoopNet, Inc. This category also includes fees for consents and assistance with and review of documents filed with the SEC.

Audit Related Fees include fees associated with assurance and related services that are reasonably related to the performance of the audit or review of CoStar’s financial statements. For fiscal year 2012, the reported audit related fees represent fees for accounting services billed by Ernst & Young LLP primarily in connection with accounting consultations about the application of generally accepted accounting principles to proposed transactions. For fiscal year 2013, the reported audit related fees represent fees for accounting services billed by Ernst & Young LLP primarily in connection with accounting consultations about the application of generally accepted accounting principles to proposed transactions as well as a debt compliance letter issued by Ernst & Young LLP for the Company’s term loan facility and revolving credit facility.

Tax Fees primarily include fees associated with tax return preparation, tax compliance, tax advice and tax planning.

AUDIT COMMITTEE PRE-APPROVAL POLICY

The Audit Committee’s policy is that all audit and non-audit services provided by CoStar’s independent registered public accounting firm shall either be approved before the independent registered public accounting firm is engaged for the particular services or shall be rendered pursuant to pre-approval procedures established by the Audit Committee. These services may include audit services and permissible audit-related services, tax services and other services. Pre-approval spending limits for services to be performed by CoStar’s independent registered public accounting firm are

established on an annual (for audit services) or periodic (for permissible non-audit services) basis, detailed as to a particular service or category of services to be performed and implemented by CoStar’s financial officers. Any audit or non-audit service fees that may be incurred by CoStar that fall outside the limits pre-approved by the Audit Committee for a particular service or category of services must be reviewed and approved by the Chairperson of the Audit Committee or the Audit Committee as a whole prior to the performance of services. CoStar’s Chief Financial Officer or General Counsel reports to the Audit Committee on a quarterly basis on all services rendered by the independent registered public accounting firm for which pre-approval has been granted and all fees paid to the independent registered public accounting firm for such services since the previous quarter’s Audit Committee meeting. The Audit Committee may revise its pre-approval spending limits and policies at any time.

All fees paid to the independent registered public accounting firm in 2013 were pre-approved by the Audit Committee, and therefore no services were approved after the services were rendered pursuant to the “de minimis” exception established by the SEC for the provision of non-audit services.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” RATIFYING THE APPOINTMENT OF ERNST & YOUNG LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE COMPANY FOR 2014.

ITEM 3

ADVISORY RESOLUTION TO APPROVE

EXECUTIVE COMPENSATION

We are asking stockholders to approve, on an advisory basis, a resolution on the Company’s executive compensation as reported in this Proxy Statement. As described below in the “Compensation Discussion and Analysis” section of this Proxy Statement, the Compensation Committee has structured our executive compensation program to achieve the following key objectives:


•	link executive compensation with the achievement of overall corporate goals,


•	encourage and reward superior performance, and


•	assist the Company in attracting, motivating and retaining talented executives.

Our Compensation Committee supports a pay-for-performance approach to executive compensation, coupled with the key objectives set forth above. Our executive compensation program has a number of features designed to promote these objectives and is designed to motivate our executives to successfully manage and grow our business.

We also value stockholder feedback. In 2013, the Company proactively reached out to stockholders to discuss the Company’s executive compensation program and to address any stockholder concerns. The Company spoke with stockholders representing approximately 78% of the outstanding common stock of the Company, including the top 30 stockholders representing approximately 70% of the outstanding common stock of the Company. In conversations between the Company and these stockholders during 2013, in addition to expressing positive views regarding the Company’s management team and outstanding total shareholder return (TSR), the stockholders expressed concern regarding (1) the lack of a long-term performance component within our executive compensation program, (2) our practice of determining executives’ annual cash incentive and performance-based stock awards using the same performance metrics, (3) a desire for more robust corporate governance policies, and (4) the size of a special one-time equity grant issued in 2012. After our 2013 annual stockholders’ meeting, the Compensation Committee responded to the specific concerns raised by stockholders. The key changes to the executive compensation program following the 2013 annual stockholders’ meeting are noted below.

•

Revised Equity Incentive Plan to Increase Performance Focus and Provide for Multi-Year Performance Metric. The Compensation Committee restructured the equity incentive program to include a performance-based component. Commencing in 2014, the restructured program consists of annual grants of performance-based restricted stock and options that vest over time and a grant of restricted stock that vests based on achievement of a three-year cumulative financial goal and is subject to adjustment based on the Company’s total stockholder return over the three-year period. The third component includes:


◦	a three-year, cumulative revenue goal to align executive compensation with long-term stockholder value; and


◦	a measure of stockholder return, whereby the shares earned, if any, as a result of the Company’s three-year revenue relative to the revenue goal will be positively or negatively adjusted based on the Company’s three-year TSR relative to the three-year TSR of the companies included within the Russell 1000 index, in order to align executive compensation with long-term stockholder returns.

Because the 2013 grants awarded for 2012 performance were issued in early 2013 prior to the 2013 “say-on-pay” vote and subsequent restructuring of the equity program, the changes discussed above could not be made, and are not applicable, to those awards.

•

Adopted Distinct Performance Metrics for the Annual and Long-Term Incentive Plans. The Compensation Committee evaluated and revised the financial metrics for both the annual awards of cash incentives and performance-based stock. Previously, executive performance for both the annual performance-based restricted stock awards and a portion of the annual cash incentive awards was evaluated using the same set of financial metrics. The special one-time equity grant issued in 2012 was also based on a similar performance metric. In response to stockholders’ concerns regarding use of overlapping metrics, the Compensation Committee revised the financial metrics for the annual awards of cash incentives and

performance-based restricted stock, so that the awards are evaluated on distinct earnings metrics. Further, the financial metric on which the three-year performance-based restricted stock awards will be evaluated is a separate and distinct revenue metric.

•

Smaller Aggregate Equity Grants in 2013. With respect to the executives’ equity compensation granted in 2013, the Compensation Committee generally strove to set target equity award values within +/- 15% of the median peer values to avoid potential payouts that could be multiple times higher than the median of the executives’ respective peers. There were no additional, special equity grants issued in 2013 or 2014.

•

Executive and Director Stock Ownership Policies. The Compensation Committee adopted an Executive Stock Ownership Policy requiring the Chief Executive Officer and President to own Company common stock with a value equal to six times his annual base salary and each other executive officer to own Company common stock with a value equal to at least two times his or her annual base salary. The Compensation Committee adopted a similar policy in 2013 requiring each director to own shares of Company common stock equal to 5 times the annual, standard director cash retainer.

•

Clawback Policy. The Compensation Committee approved a clawback policy that requires the Board to review cash incentive payments to executive officers and all performance-based equity awards issued to executive officers during the three years prior to the date the Company determines a restatement is required, if any, and to seek recoupment from executive officers who engaged in willful misconduct or gross negligence in the event that payments or grants would have been lower if determined based on the restated results.


•	Corporate Governance Guidelines. The Board, on the recommendation of the Nominating & Corporate Governance Committee, adopted the Company’s Principles of Corporate Governance to assist the Board in carrying out its responsibilities and to set forth the Board’s current views with respect to selected corporate governance matters considered to be of significance to our stockholders

We believe the changes made address the specific concerns raised by our stockholders and further the objectives of the executive compensation program. We also believe that stockholders’ interests are further served by other executive compensation-related practices and policies that we have adopted. We don’t provide material perquisites to our executive officers, and we don’t have the ability to reprice options without stockholder approval. Further, our Compensation Committee regularly retains an independent compensation consultant to advise the Committee on evolving best practices on executive compensation and with respect to the Company’s compensation peer group.

We urge stockholders to read the “Compensation Discussion and Analysis” beginning on page 29 of this Proxy Statement, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and other related compensation tables and narrative, appearing on pages 56 through 62, which provide detailed information on the compensation of our named executive officers. The Compensation Committee and the Board of Directors believe that the policies and procedures articulated in the “Compensation Discussion and Analysis” are effective in achieving our goals and that the compensation of our named executive officers reported in this Proxy Statement has supported and contributed to the Company’s recent and long-term success.

In accordance with Section 14A of the Exchange Act, and as a matter of good corporate governance, we are asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the stockholders of CoStar Group, Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers disclosed in the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables, notes and narrative in the Proxy Statement for the Company’s 2014 Annual Meeting of Stockholders.

This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board. Although non-binding, the Board and the Compensation Committee will review and consider the voting results when making future decisions regarding our executive compensation program. The Company provided its stockholders a “say-on-pay” advisory vote to approve its executive compensation in 2013. At the 2013 Annual Meeting, approximately 64% of the votes cast were for approval of the “say-on-pay” advisory vote. The Committee evaluated the results of the 2013 advisory vote in connection with its evaluation of the Company’s executive compensation programs generally and, as

noted above, the Committee elected to make changes to the Company’s executive compensation program to address concerns raised in conversations with representative stockholders, while retaining the Committee’s emphasis on linking executive incentives with long-term stockholder value.

At our annual meeting of stockholders held on June 2, 2011, our stockholders voted to adopt the recommendation of our Board to vote on the say-on-pay proposal every year at our annual meeting. As a result, we expect to continue to submit our say-on-pay proposal to our stockholders at each annual meeting. We expect to ask our stockholders to vote on a proposal regarding the frequency of the vote on the say-on-pay proposal at our 2017 Annual Meeting, as required by the Dodd-Frank Act.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE ADVISORY RESOLUTION ON EXECUTIVE COMPENSATION.

OTHER MATTERS

We do not know of any other matter that will be presented for consideration at the Annual Meeting. If any other matter does properly come before the Annual Meeting, the proxy holders will, unless otherwise specified in the proxy, vote on it as they think best in their discretion.

STOCKHOLDER PROPOSALS AND NOMINATIONS FOR DIRECTORS FOR THE 2015 ANNUAL MEETING

A stockholder who intends to introduce a proposal for consideration at our 2015 Annual Meeting of Stockholders may seek to have that proposal and a statement in support of the proposal included in our Proxy Statement if the proposal relates to a subject that is permitted under Rule 14a-8 under the Exchange Act. Additionally, in order to be eligible for inclusion in our Proxy Statement, the stockholder must submit the proposal and supporting statement to our Corporate Secretary in writing not later than December 23, 2014, and must satisfy the other requirements of Rule 14a-8. Stockholders interested in submitting such a proposal are advised to contact knowledgeable counsel with regard to the detailed requirements of applicable securities laws. The submission of a stockholder proposal does not guarantee that it will be included in our Proxy Statement.

A stockholder may otherwise propose business for consideration or nominate persons for election to the Board, in compliance with federal proxy rules, applicable state law and other legal requirements and without seeking to have the proposal included in our Proxy Statement pursuant to Rule 14a-8. Our Amended and Restated Bylaws provide that any such proposals or nominations must be submitted to us not later than the close of business on the 75^th day and not earlier than the close of business on the 105^th day before the first anniversary date of the preceding year’s annual meeting. In the event that the date of the Company’s annual meeting is more than 30 days before or more than 70 days after the first anniversary of the preceding year’s annual meeting (other than as a result of adjournment or postponement), then, to be timely, such stockholder’s notice must be submitted in writing not earlier than the close of business on the 105^th day prior to such annual meeting and not later than the close of business on the later of the 75^th day prior to such annual meeting or the 10^th day following the date on which the public announcement of the date of such meeting is first made by the Company. Accordingly, stockholders who wish to nominate persons for election as directors or bring forth other proposals outside of Rule 14a-8 at the 2015 Annual Meeting must give notice of their intention to do so in writing to our Corporate Secretary on or before March 19, 2015, but no sooner than February 17, 2015. The stockholder’s submission must include certain specified information concerning the proposal or nominee, as the case may be, and information as to the stockholder’s ownership of common stock as required by the Company’s Amended and Restated Bylaws. Stockholder proposals or nominations not meeting these requirements will not be entertained at the 2015 Annual Meeting.

ADDITIONAL INFORMATION

Corporate Governance Matters

Corporate Governance Guidelines

The Board, on the recommendation of the Nominating & Corporate Governance Committee, has adopted the Company’s Principles of Corporate Governance to assist the Board in carrying out its responsibilities and to set forth the Board’s current views with respect to selected corporate governance matters considered to be of significance to our stockholders. The Company’s Principles of Corporate Governance direct our Board’s actions with respect to, among other things, Board composition, director membership criteria, composition of the Board’s standing committees, and the Board’s performance evaluations. The Company’s Principles of Corporate Governance can be found on the Investors section of the Company’s website at www.CoStar.com/Investors/CorpGovernance.aspx.

Identifying and Evaluating Nominees

The Nominating & Corporate Governance Committee identifies nominees for director on its own as well as by considering recommendations from other members of the Board, officers and employees of CoStar, and other sources that the Nominating & Corporate Governance Committee deems appropriate. The Nominating & Corporate Governance Committee will also consider Board nominees suggested by stockholders, subject to such recommendations being submitted during the period and including the required information specified in CoStar’s Amended and Restated Bylaws for stockholders to nominate directors, as described under “Stockholder Proposals and Nominations for Directors for the 2015 Annual Meeting” above. The Company may require any proposed nominee to furnish other information as reasonably required to determine eligibility to serve as a director of the Company, including information regarding the proposed nominee’s independence.

When evaluating nominees for director, the Nominating & Corporate Governance Committee considers, among other things, an individual’s business experience and skills, background, independence, judgment, integrity and ability to commit sufficient time and attention to the activities of the Board, as well as the absence of any potential conflicts with the Company’s interests. When considering a director standing for reelection as a nominee, in addition to the attributes described above, the Nominating & Corporate Governance Committee also considers that individual’s past contribution and future commitment to CoStar. The Nominating & Corporate Governance Committee evaluates the totality of the merits of each prospective nominee that it considers and does not restrict itself by establishing minimum qualifications or attributes. The Nominating & Corporate Governance Committee evaluates candidates within the context of the perceived needs of the Board as a whole, so that the members of the Board collectively will possess the necessary skills, experience and background. While the Nominating & Corporate Governance Committee does not have a formal policy with respect to diversity, the committee believes that it is important that Board members represent diverse viewpoints. There is no difference in the manner by which the Nominating & Corporate Governance Committee evaluates prospective nominees for director based on the source from which the individual was first identified.

Board Leadership Structure

Currently, an independent director, Mr. Klein, serves as Chairman of the Board and a separate director, Mr. Florance, serves as Chief Executive Officer. Mr. Klein has served on the Company’s Board of Directors since inception and is well positioned to serve as Chairman of the Board. The Board does not have a policy regarding the separation of the roles of Chief Executive Officer and Chairman of the Board as the Board believes it is in the best interests of the Company to make that determination based on the position and direction of the Company and the membership of the Board at the particular time. The Board has determined that this leadership structure, under which the roles of Chairman and CEO are separate and an independent director serves as Chairman, currently is in the best interest of the Company’s stockholders. This structure provides a greater role for the independent directors in the oversight of the Company and in setting agendas and establishing Board priorities and procedures. In addition, this structure permits the Chief Executive Officer to focus on the management of the Company’s day-to-day operations.

Independent Directors and Executive Sessions

CoStar’s Board has determined that Messrs. Klein, Bonderman, Glosserman, Haber, Hill, Nassetta, and Steinberg are each independent as defined under Rule 5605(a)(2) of the Nasdaq listing rules. As part of the Board’s determination of each member’s independence, the Board was presented with information regarding Mr. Klein’s position as Chairman of the Shakespeare Theatre Company, a non-profit organization, Mr. Florance’s and Mr. Hill’s positions on the board of the Shakespeare Theatre Company, and Mr. Glosserman’s position as Honorary Trustee of the National Building Museum, an independent non-profit organization. The Company expensed contributions to The Shakespeare Theatre Company of $55,000 in each of the last three fiscal years. The Company expensed contributions and other payments to the National Building Museum of less than $90,000 in each of the last three fiscal years. In addition, the Board considered that Messrs. Bonderman, Glosserman and Nassetta each serve as executive officers of companies that subscribe to the Company’s services and that in each case the payments to the Company were less than one percent of the consolidated gross annual revenues of the Company in each of the last three fiscal years. Further, the Board

considered that the services provided to those companies by the Company are on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances.

The independent directors of the Board of Directors meet in regularly scheduled executive sessions, which are typically run by the Chairman of the Board, Mr. Klein. In 2013, the independent directors met in executive session at one quarter of the regularly scheduled meetings of the Board of Directors (one time).

The Board’s Role in Risk Oversight

One of the Board’s functions is oversight of risk management at CoStar. This risk oversight function is administered both through the full Board and through individual Board Committees that are tasked by the Board with oversight of specific risks, as described below.

Companies face a variety of risks, including macro-economic risks, such as inflation, economic downturns, or recession; business-specific risks related to strategic position, operations, financial structure, legal and regulatory compliance and corporate governance; and event-specific risks, such as natural disasters or wars. The Company believes that an effective risk management system will:


•	timely identify the material risks that the Company faces,


•	communicate necessary information with respect to material risks to senior executives and, as appropriate, to the Board or relevant Board Committee,


•	implement appropriate and responsive risk management strategies consistent with the Company’s risk profile, and


•	integrate risk management into Company decision-making.

The Board believes that our leadership structure, discussed under “Board Leadership Structure” above, supports the risk oversight function of the Board. We have an independent director serving as Chairman of the Board and a separate director serving as Chief Executive Officer. In addition, independent directors chair and serve on the various committees involved with risk oversight.

The Board encourages management to promote a corporate culture that incorporates risk management into the Company’s corporate strategy and day-to-day business operations. Management is responsible for identifying risk and risk controls related to significant business activities and developing programs and recommendations to determine the sufficiency of risk identification, the balance of potential risk to potential reward, and the appropriate manner in which to control risk.

The Board implements its risk oversight responsibilities by having management, typically the Chief Financial Officer or General Counsel, provide periodic briefing and informational sessions on the significant voluntary and involuntary risks that the Company faces and how the Company is seeking to control risk if and when appropriate. When appropriate, other members of management will provide information to the Board or one of its committees with respect to a specific area of potential risk and how the Company manages or seeks to control the identified risk. In some cases, as with risks related to product or service acceptance, risk oversight is addressed as part of the full Board’s engagement with the Chief Executive Officer and management. In other cases, a Board Committee is responsible for oversight of specific risk topics, in which case management meets directly with the Board Committee. For example, the Audit Committee oversees issues related to internal control over financial reporting and issues related to the Company’s risk tolerance in cash-management investments, and the Compensation Committee oversees risks related to compensation plans and programs, as discussed in greater detail below. The Company’s Audit Committee meets regularly and the Compensation and Nominating & Corporate Governance Committees meet at least annually, and each Committee reports back to the full Board. The Board also works with the Company’s management to assess, analyze and address the most likely areas of future risk for the Company.

Risk Assessment in Compensation Programs

We have assessed the Company’s compensation programs. Management assessed the Company’s executive and broad-based compensation and benefits programs to determine if the programs’ provisions and operations encourage or create undesired or unintentional risk of a material nature. This risk assessment process included:


•	a review of CoStar’s compensation programs’ policies and practices;


•	program analysis to identify risk and risk control related to the programs; and


•	determinations as to the sufficiency of risk identification, the balance of potential risk to potential reward and risk control.

Although we reviewed all compensation programs, we focused on the programs with variability of payout, with the ability of a participant to directly affect payout and the controls on participant action and payout. The Company supports the use of base salary, performance-based compensation, and retirement plans that are generally uniform in design and operation throughout the Company. In most cases, the compensation policies and practices are centrally designed and administered, and are substantially identical at each business unit, except that sales personnel are also eligible to receive sales commissions depending upon performance. Programs may differ by country due to variations in local laws and customs.

Based on the foregoing, we believe that our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company. We also believe that our incentive compensation arrangements provide incentives that do not encourage risk-taking beyond the organization’s ability to effectively identify and manage significant risks; are compatible with effective internal controls and the risk management practices of the Company; and are supported by the oversight and administration of the Compensation Committee with regard to executive compensation programs.

Stockholder Communications with the Board

Stockholders may communicate with our Board by sending written correspondence to CoStar Group, Inc., Attention: Corporate Secretary, 1331 L Street N.W., Washington, DC 20005. Such communications will be opened by the Corporate Secretary. A copy of the contents will be made and retained by the Corporate Secretary and the contents will be promptly forwarded to the Chairman of the Nominating & Corporate Governance Committee and, if addressed to a particular committee or Board member, to that committee’s Chairman or the particular Board member. The Corporate Secretary together with the Chairman of the Nominating & Corporate Governance Committee and his duly authorized agents are responsible for collecting and organizing stockholder communications. Absent a conflict of interest, the Chairman of the Nominating & Corporate Governance Committee is responsible for evaluating the materiality of each stockholder communication and determining which stockholder communications are to be presented to the full Board, individual directors or other appropriate body.

Policy Regarding Attendance at Annual Meetings

CoStar encourages, but does not require, directors to attend the Annual Meetings of Stockholders. In 2013, three directors attended the Annual Meeting of Stockholders.

Board Meetings and Committees

In accordance with applicable Delaware law and the Company’s Amended and Restated Bylaws, the business and affairs of the Company are managed under the direction of its Board. The Board, which is elected by the Company’s stockholders, is the ultimate decision-making body of the Company except with respect to those matters reserved to the stockholders. The Board selects, advises and monitors the performance of the Company’s senior management team, which is charged with the conduct of the Company’s business. The Board has established certain standing committees to assist it in fulfilling its responsibilities as described below.

During 2013, the Board of Directors held four meetings. The Board has Audit, Compensation and Nominating & Corporate Governance committees. During 2013, each director attended at least 75 percent of the aggregate of the total number of meetings of the Board held during the period in which he was a director and the total number of meetings held by all of the committees of the Board on which he served during the period of his service on the committee.

The Audit Committee is also responsible for producing the report of the Audit Committee for inclusion in the Company’s Proxy Statement. The Audit Committee operates under a written charter adopted by the Board and reviewed annually by the Audit Committee.

Compensation Committee. The Board has determined that each of the current members of our Compensation Committee is independent as defined under Rule 5605(a)(2) of the Nasdaq listing rules. The Compensation Committee operates under a written charter adopted by the Board and reviewed annually by the Compensation Committee.

The purpose of the Compensation Committee is to discharge the responsibilities of the Board relating to compensation of the Company’s executive officers and directors, as well as to oversee production of the Compensation Committee report on executive compensation for inclusion in the Company’s Proxy Statement. The Compensation Committee’s authority and responsibilities include:

reviewing and discussing with management the Company’s compensation discussion and analysis and related disclosures required to be included in the Company’s annual report and proxy statement, recommending to the Board whether the compensation discussion and analysis should be included in the annual report and proxy statement, and overseeing publication of an annual executive compensation report in the Company’s annual report and proxy statement.

In addition, the Board has designated the Compensation Committee as the Administrator of the Company’s 1998 Stock Incentive Plan, as amended (the “1998 Plan”), the Company’s 2007 Stock Incentive Plan, as amended (the “2007 Plan”), and the Company’s 2011 Cash Incentive Plan (the “2011 Incentive Plan”). The Compensation Committee may delegate its duties or responsibilities to a subcommittee of the Compensation Committee, and it has authority to retain and to direct management to retain outside advisors and experts that it determines appropriate to assist with performance of its functions.

Our Chief Executive Officer and Chief Financial Officer make recommendations to the Compensation Committee for each element of compensation awarded to executives, but the Compensation Committee must approve each element of (and any changes to) executive compensation. Periodically, the Compensation Committee also retains independent compensation consulting firms to assist it in gathering market data and to provide it with information about trends in compensation among comparable companies, determined based on factors such as market capitalization, annual revenues, service offerings, and potential competition for talent or business. The Compensation Committee retained Towers Watson in 2013, and utilized the findings from its study in connection with the Company’s executive compensation decisions for 2013 and 2014, as discussed below in the section titled “Compensation Discussion and Analysis” beginning on page 29 of this Proxy Statement. Towers Watson reported directly to the Compensation Committee through its chair and, at the direction of the Compensation Committee chair, also worked directly with the Company’s management to develop materials and proposals with respect to executive officer compensation. In future years, the Compensation Committee may at its discretion retain Towers Watson (or another consulting firm) to update or perform new studies to be used in connection with its executive compensation decisions.

Our Compensation Committee has reviewed an assessment of the independence of, and any potential conflicts of interest raised by, Towers Watson’s work for the Compensation Committee by considering the following six factors (i) the provision of other services to us by Towers Watson; (ii) the amount of fees received from us by Towers Watson, as a percentage of the total revenue of Towers Watson; (iii) the policies and procedures of Towers Watson that are designed to prevent conflicts of interest; (iv) any business or personal relationship of the Towers Watson consultant with a member of the Compensation Committee; (v) any Company stock owned by the Towers Watson consultant; and (vi) any business or personal relationship of the Towers Watson consultant or Towers Watson with any of our executive officers, and concluded that Towers Watson is independent and there are no such conflicts of interest.

Nominating & Corporate Governance Committee. The Board has determined that each of the current members of our Nominating & Corporate Governance Committee is independent as defined under Rule 5605(a)(2) of the Nasdaq listing rules. The purpose of the Nominating & Corporate Governance Committee is to identify individuals qualified to become Board members, recommend to the Board director candidates to be nominated at the Annual Meeting of Stockholders and perform a leadership role in shaping the Company’s corporate governance. The Nominating & Corporate Governance Committee operates under a written charter adopted by the Board and reviewed annually by the Nominating & Corporate Governance Committee.

All of the charters for the Company’s Board committees are available in the “Investors” section of the Company’s website at www.CoStar.com/Investors/Corpgovernance.aspx.

Report of the Audit Committee

The Audit Committee reviews the Company’s financial reporting process on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process. The Company’s independent registered public accounting firm is responsible for expressing an opinion on the conformity of the Company’s audited consolidated financial statements to generally accepted accounting principles.

In this context, the Audit Committee has reviewed and discussed with management and the independent registered public accounting firm the Company’s audited consolidated financial statements for 2013. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board (the “PCAOB”). In addition, the Audit Committee has received from the independent registered public accounting firm the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with the independent registered public accounting firm its independence from the Company and management. The Audit Committee has also considered whether the independent registered public accounting firm’s provision of non-audit services to the Company is compatible with the auditors’ independence.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the Company’s annual report on Form 10-K for the year ended December 31, 2013, for filing with the SEC.

Director Compensation

The Compensation Committee of the Board annually reviews director compensation for service on the Board and for service on any Board committees and recommends director compensation and any changes to such compensation to the Board for approval. The Board annually reviews and approves director compensation for Board and committee service based on the recommendations of the Compensation Committee. The Compensation Committee engaged Towers Watson, an independent compensation consultant, in 2013 to assess the competitiveness of the non-employee directors’ compensation program. In connection with its review, Towers Watson updated the Company’s peer group, which was approved by the Compensation Committee and then utilized to analyze both director and executive compensation. The review demonstrated that the Company’s non-employee directors’ total compensation ranked lowest in the Company’s peer group, but that the Chairman’s chair compensation fell at the median of the peer group. As a result, the Compensation Committee recommended to the Board to increase director compensation to bring the annual, standard retainer and annual equity grants to non-employee directors in line with median levels of peer company data provided by the compensation consultant, to provide compensation to committee members in line with median levels of peer company data and to make non-employee director compensation more competitive in the marketplace.

On September 19, 2013, the Compensation Committee and the Board approved changes to the non-employee director compensation effective as of that date. Non-employee director compensation for 2013 is set out below, including compensation prior to and as of the changes on September 19, 2013. Directors who are also employees of the Company do not receive any compensation for service on the Board in addition to their regular employee compensation.

(1) The Company reimburses all directors for reasonable travel and out-of-pocket expenses incurred in connection with their duties as directors, including attendance at meetings.
(2) Annual equity awards are granted on the date of the first regular Board meeting following the date of the annual meeting of stockholders, are payable in the form of restricted stock, are valued at the grant date, and vest in equal, annual installments over a 4-year period from the date of grant as long as the director is still serving on our Board on the respective vesting date. The number of shares of restricted stock granted pursuant to each such restricted stock grant to the directors is determined by dividing the total dollar amount awarded by the closing price of the Company’s common stock on the date of grant.

Pursuant to the Company’s 1998 and 2007 Plans and related award agreements, upon a change of control, all restrictions on stock grants will lapse. For more detailed information, see “Change of Control Provisions under the Company’s 1998 and 2007 Plans” beginning on page 64. In addition, under the 1998 and 2007 Plans, recipients of restricted stock are entitled to receive dividends and other distributions, if any, paid with respect to the common stock. The Compensation Committee will determine if any such dividends or distributions will be automatically reinvested in additional shares of restricted stock and subject to the same restrictions as the restricted stock or whether the dividend or distribution will be paid in cash.

Director Stock Ownership Policy

The Compensation Committee adopted stock ownership requirements for the Company’s non-employee directors as set forth in the Company’s Director Stock Ownership Policy. Each non-employee director is required to own shares of the Company’s common stock with a value equal to five times the annual, standard director cash retainer. The current directors have until December 31, 2018 to meet the ownership requirement.

Consists of the following plans: the 1998 Plan, the 2007 Plan and the Company’s Employee Stock Purchase Plan. The Company’s 1998 Plan and the Company’s 2007 Plan provide for various types of awards, including options and restricted stock grants. In April 2007, the Company’s Board of Directors adopted the 2007 Plan, subject to stockholder approval, which was obtained on June 7, 2007. The 2007 Plan was amended in June 2010, June 2011 and June 2012. Stockholders approved these amendments on June 2, 2010, June 2, 2011, and June 5, 2012, respectively. 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 remained available for issuance pursuant to new awards under the 1998 Plan. The 1998 Plan continues to govern unexercised and unexpired awards issued under the 1998 Plan prior to June 7, 2007. The Employee Stock Purchase Plan was adopted by the Board of Directors on April 17, 2006, and approved by the Company’s stockholders on June 8, 2006. The Employee Stock Purchase Plan was later amended by the Board of Directors on July 1, 2006 and January 1, 2010. Those amendments to the Employee Stock Purchase Plan were ministerial in nature and were not subject to stockholder approval.


(2)	Includes 34,895 shares of common stock available for future issuance under the Company’s stockholder-approved Employee Stock Purchase Plan, which amount includes 257 shares subject to purchase during the then-current purchase period.

EXECUTIVE SUMMARY

BUSINESS OVERVIEW

CoStar Group is the leading provider of commercial real estate information, analytics and marketplaces. Founded in 1987, CoStar conducts expansive, ongoing research to produce and maintain the largest and most comprehensive database of commercial real estate information. Headquartered in Washington, DC, CoStar maintains offices throughout the U.S. and in Europe with a staff of over 2,300 worldwide, including the industry's largest professional research organization

EXECUTIVE COMPENSATION PLAN AND PERFORMANCE HIGHLIGHTS

CoStar Group’s executive compensation program is designed to hold our executives accountable for corporate results over the short and long term, and to reward them for successful execution. As a result, a substantial portion of our executives’ overall compensation is tied to performance. The charts below illustrate the percentage of 2013 compensation (based on target award opportunities) that was performance based, including cash incentives, restricted stock and options, and the percentage that is fixed, consisting of base salary.

The Compensation Committee links executive compensation to the attainment of challenging goals. Cash compensation includes payments under our annual cash incentive plan that are based on company performance relative to operational goals as well as individual performance. Equity-based compensation is used to align executive compensation with the long-term interests of our stockholders, including a focus on increasing the Company’s total shareholder return (TSR). Over the past three calendar years, the Company’s TSR was 47%. In comparison, the TSR for the S&P 500 Internet Software & Services Index to which we are currently compared was 23% over the same time period. In 2013, CoStar’s TSR was 107%, while the TSR for the S&P 500 Internet Software & Services Index was 49% over the same time period.

The Company’s executive compensation for 2013 reflects our financial and operational results. The Company’s achievement of outstanding earnings results in 2013 resulted in the executive officers’ achieving 200% credit for their adjusted EBITDA and non-GAAP net income goals tied to their annual cash and stock incentive awards.

Performance for the Year 2013

2013 STOCKHOLDER OUTREACH AND SAY ON PAY RESPONSE

CoStar annually offers stockholders the opportunity to cast an advisory vote on our executive compensation program. This annual vote is known as the “say-on-pay” proposal. At our annual meeting in June 2013, approximately 64% voted in favor of the say-on-pay proposal covering our executive compensation program for 2012. Although a majority of stockholders expressed support for the compensation of the Company’s named executive officers, the Compensation Committee values any additional stockholder feedback and endeavors to respond to stockholders’ concerns. We regularly communicate with our stockholders to better understand their opinions on our business strategy and objectives and to obtain feedback regarding other matters of investor interest, such as executive compensation. Throughout 2013, in addition to our regular communications with stockholders during which the Company receives feedback in the normal course, we engaged in a focused outreach effort to many of our institutional stockholders to solicit their feedback on our executive pay program as well as potential changes for fiscal year 2014.

In 2013, the Company proactively reached out to stockholders to discuss the Company’s executive compensation philosophy, goals and plans and to obtain an understanding of our stockholders’ concerns. The Company spoke with stockholders representing approximately 78% of the Company’s outstanding common stock, including the top 30 stockholders who represent approximately 70% of the Company’s outstanding common stock to better understand their votes on the 2013 “say-on-pay” proposal and obtain feedback on executive compensation. Many of those stockholders expressed very positive views regarding the Company’s strong and stable management team and the outstanding TSR enjoyed by stockholders. They also expressed a desire for changes in the compensation plans, including 1) addition of a multi-year performance component, 2) elimination, or limitation on use, of overlapping metrics as goals for different executive compensation plan components, 3) implementation of more robust governance policies, and 4) limitation on the overall size of equity awards, relating to a concern focused on a special performance-based equity grant awarded in 2012.

The Compensation Committee carefully considered this feedback as part of its annual review of our executive compensation program and has responded to the stockholder concerns communicated to it. The Compensation Committee approved several changes to the Company’s executive compensation program and corporate governance practices after the 2013 annual meeting.



Stockholder Concern/Reason for Change	Compensation Program Change
Stockholders’ concern that executives’ annual restricted stock grants vest ratably over time following achievement of the annual performance goal, rather than vesting based on achievement of a performance goal.	Revised equity incentive plan to increase performance focus. The plan was restructured by adjusting the mix of equity grants to 40% annual performance-based restricted stock, 40% stock options, and 20% long-term performance shares.
Stockholder feedback that the performance period for the long-term incentive performance metric should be longer than one year.	Revised equity incentive plan to provide for a three-year performance metric for the long-term performance shares.
Improved stockholder alignment	In order to even more closely align long-term incentives with stockholder results, the restructured equity incentive plan provides for adjustment of the long-term performance shares issued to executives based on the Company’s total shareholder return relative to the Russell 1000 index.
Stockholder feedback that performance metrics should differ in annual and long-term incentive plans.	Adopted distinct performance metrics as follows: • Annual incentive plan – adjusted EBITDA and individual objectives • Performance-based restricted stock – non-GAAP net income • Performance shares – 3-year cumulative revenue goal, adjusted by relative total shareholder return (measured against the Russell 1000 index)
Stockholders’ concern regarding size of the special one-time equity grants issued in 2012.	Aggregate equity compensation granted to executives in 2013 generally targeted within +/15% of the median peer values.
Stockholder feedback that there is a desire for more robust executive compensation corporate governance policies.	Adopted executive and Director stock ownership policies as follows: • CEO and President – 6X base salary • Other executive officers - 2X base salary • Non-employee Directors – 5X annual, standard Director cash retainer
Stockholder feedback that there is a desire for more robust executive compensation corporate governance policies	Adopted a clawback policy
Improved corporate governance	Adopted the Company’s Principles of Corporate Governance

Revised Equity Incentive Plan to Increase Performance Focus and Provide for Multi-Year Performance Metric: The Compensation Committee acknowledged stockholders’ concern that the executives’ annual restricted stock grants vest ratably over three years following achievement of the annual performance goal and subsequent grant. In response to stockholders’ preference that some component of the executive compensation program be based on the accomplishment of pre-determined, objective goals over a multi-year period, in early 2014, the Compensation Committee restructured the executive equity compensation program to include a multi-year performance component. As restructured, the equity program consists of 40% annual grants of performance-based restricted stock and 40% options, each of which vest over time after grant, and 20% restricted stock that vests based on achievement of a three-year cumulative revenue goal and is subject to adjustment based on the Company’s total stockholder return over the three-year period. The three-year performance component includes:


•	a three-year, cumulative revenue goal to incentivize executives to focus on the goals established for the three-year performance period and align executive compensation with long-term stockholder value and provide a direct link in the long-term incentive plan to long-term revenue growth; and

•

a measure of stockholder return, whereby the shares earned, if any, as a result of the Company’s three-year revenue relative to the revenue goal will be positively or negatively adjusted based on the Company’s three-year TSR relative to the three-year TSR of the companies included within the Russell 1000 index, in order to tie the value of the equity awards to the Company’s performance and appreciation of the Company’s stock price relative to the performance of other companies within the index. The Committee chose the Russell 1000 index in order to closely align the three-year performance goal with that of the U.S. equity market. The Russell 1000 measures the performance of the large cap segment of the U.S. equity markets and represents approximately 92% of the U.S. market as measured by capitalization. The Committee determined that the Russell 1000 index would provide a comprehensive and unbiased barometer against which to compare the Company’s TSR.

Adopted Distinct Performance Metrics for the Annual and Long-Term Incentive Plans: The Compensation Committee removed overlapping metrics from the Company’s incentive compensation awards to avoid any potential for duplicative payouts for the same areas of performance. Previously, executive performance for both the annual performance-based restricted stock awards and a portion of the annual cash incentive awards was evaluated using the same set of financial metrics, revenue and EBITDA. The special one-time equity grant issued in 2012 was also subject to vesting based on achievement of an EBITDA goal. In response to stockholders’ concerns regarding use of overlapping metrics, as heard by the Company through its stockholder outreach program, the Compensation Committee revised the financial metrics for the annual awards of cash incentives and performance-based restricted stock. The annual cash incentive awards for 2013 were determined, and the annual cash incentive awards for 2014 will be determined, based on achievement of adjusted EBITDA and individual, subjective goals for the respective year, while the 2013 annual performance-based stock awards were determined, and the 2014 annual performance-based stock awards will be determined, based on achievement of non-GAAP net income for the respective year. As mentioned above, the three-year performance based restricted stock award will vest based on achievement of a three-year aggregate revenue performance goal.

Smaller Aggregate Equity Grants in 2013: In 2012, the Compensation Committee approved a special performance-based restricted common stock grant, subject to vesting upon the Company’s achievement of $90 million of cumulative EBITDA over a period of four consecutive calendar quarters, provided that the performance criteria is met by March 31, 2017. The Compensation Committee set what it believed to be a highly rigorous goal. The special performance-based grant was awarded in order to increase executives’ focus on longer-term financial goals, enhance parity between the Company’s executives and those who joined the Company from acquired entities, and to continue to increase equity ownership levels to more competitive levels. To achieve those goals, the award value granted to the named executive officers was larger than the annual target award values set by the Committee for the annual equity awards. With respect to the executives’ equity compensation granted in 2013, the Compensation Committee generally strove to set target equity award values within +/- 15% of the median peer values to avoid potential payouts that could be multiple times higher than the median of the executives’ respective peers. There were no additional, special equity grants issued in 2013 or 2014.

Executive and Director Stock Ownership Policies: The Compensation Committee recently approved an Executive Stock Ownership Policy requiring (1) the Company’s Chief Executive Officer and President to own shares of Company common stock with a value equal to six times the executive’s annual base salary, and (2) each other executive officer to own shares of Company common stock with a value equal to at least two times the respective executive’s annual base salary. The current executive officers have until December 31, 2019 to meet the ownership requirements. The Compensation Committee adopted a similar policy in 2013 requiring each director to own shares of Company common stock equal to 5 times the annual, standard director cash retainer. The current directors must meet the ownership threshold no later than December 31, 2018. The Compensation Committee believes that these policies further increase executives’ alignment with stockholder interests and incentivize executive officers and directors to maximize stockholder value.

Clawback Policy: The Compensation Committee approved a clawback policy that requires the Board to review cash incentive payments to executive officers and all performance-based equity awards issued to executive officers during the three years prior to the date the Company determines a restatement is required, if any. If the Board determines that the payments or grants would have been lower had they been determined or calculated based on the restated results, the Board will, to the extent permitted by governing law, seek to recoup for the benefit of the Company the value of such payments made to executive officers whom the Board determines engaged in willful misconduct or gross negligence. The Compensation Committee believes that this policy will lessen any potential for excessive risk-taking.

Corporate Governance Guidelines: The Board, on the recommendation of the Nominating & Corporate Governance Committee, adopted the Company’s Principles of Corporate Governance to assist the Board in carrying out its responsibilities and to set forth the Board’s current views with respect to selected corporate governance matters considered to be of significance to our stockholders.

The Compensation Committee believes that the compensation program and corporate governance policies, as improved by the changes described above, establish a foundation for long-term success and increased stockholder value. When making future compensation decisions for named executive officers, the Compensation Committee will continue to consider the opinions that stockholders express through say-on-pay votes and through conversations held throughout the year via stockholder outreach programs.

EXECUTIVE COMPENSATION PRACTICES

Below we highlight certain executive compensation practices we employ to align executive compensation with stockholder interests. Also listed below are certain compensation practices we do not employ because we do not believe they would serve our stockholders’ long-term interests.

What We Do

Pay for Performance. We tie annual pay to objective performance metrics, including our fiscal year 2013 adjusted EBITDA and non-GAAP net income. We tie long-term pay to three-year aggregate revenue and total stockholder return. We ask our independent compensation consultant to evaluate the alignment of pay and performance relative to our peer group.

Total Stockholder Return Metric. Linking executive compensation to stockholder performance is important, therefore the Compensation Committee made relative stockholder return a factor in determining performance share payouts. Further, stock options and performance-based restricted stock are awarded annually, and the value of those awards to the executives is ultimately based on stock price performance.

Executive Stock Ownership Guidelines. Executives are expected to own shares of CoStar common stock with a value equal to at least 2 to 6 times base salary, depending on position.

Vesting Period on Equity Awards. Options and annual performance-based restricted stock vest ratably over three years.

Clawback Policy. If a restatement is required and the Board determines that incentive payments or grants would have been lower had they been determined or calculated based on restated results, we can seek to recover the value of such payments made to executive officers whom the Board determines engaged in willful misconduct or gross negligence.

Target Pay. We generally target each component of pay at +/- 15% of the median of the peer group, except as may otherwise be appropriate to reflect promotions, tenure, new-hire needs, internal pay equity, etc. The Compensation Committee periodically reviews the compensation peer group and makes adjustments, when appropriate, to keep pay practices competitive and in line with investor expectations

What We Don’t Do

Limited Employment Agreements. We do not provide our named executive officers, with the exception of the chief executive officer, with employment agreements that provide severance payments, medical or insurance benefits or any other perquisites in the event the executive is terminated or resigns. A Company-wide severance policy provides minimal severance pay tied to tenure to executives when employment ends and is available generally to all salaried employees.

No Repricings. Our stock incentive plans and NASDAQ listing standards prohibit us from repricing options without stockholder approval.

EXECUTIVE COMPENSATION PROGRAM OBJECTIVES

The Company’s Compensation Committee (the “Committee”) is responsible for designing and maintaining the Company’s executive compensation program consistent with the objectives below. The Company’s executive compensation program seeks to:


•	link executive compensation with the achievement of overall corporate goals


•	encourage and reward superior performance


•	maintain competitive compensation levels in order to attract, motivate and retain talented executives


•	align executives’ interests with those of the Company’s stockholders

Accordingly, executive compensation is structured so that a significant portion of compensation paid to named executive officers is directly related to the Company’s short-term and long-term performance, thereby aligning the interests of named executive officers with those of the Company’s stockholders. For example, as discussed below, a significant portion of the named executive officers’ opportunities under the Company’s cash incentive and equity compensation programs is tied to the Company’s achievement of earnings and revenue growth objectives. The annual incentives paid to each of our named executive officers vary with individual performance and annual corporate financial results. The Committee also recognizes that the market for executives in the commercial real estate information services industry is highly competitive, and therefore seeks to provide a competitive total compensation package so that the Company may maintain its leadership position in this industry by attracting, retaining, and motivating executives capable of enhancing stockholder value.

The Committee uses its independent compensation consultant, Towers Watson, to evaluate the relationship and alignment between executive compensation for our named executive officers and our corporate performance. Towers Watson considered the alignment between the realizable compensation of our named executive officers over the last three fiscal years relative to that of the fifteen company peer group, and our performance over that period relative to those peer companies, and concluded that our pay and performance were aligned.

DETERMINING EXECUTIVE COMPENSATION

The Committee annually establishes and reviews all forms of direct compensation, including base salaries, annual incentive bonuses, and both the terms and types of equity awards, for the Company’s named executive officers as well as other officers of the Company. As part of the compensation review process, the Committee annually reviews and approves each element and the mix of compensation that comprises each named executive officer’s total compensation package. Our Chief Executive Officer and independent compensation consulting firm make recommendations to the Committee for each element of compensation awarded to named executive officers (including establishment of individual and corporate financial goals), but the Committee must approve each element of (and any changes to) a named executive officer’s compensation. The Committee may consider a number of factors in establishing or revising each named executive officer’s total compensation, including individual performance, the Company’s financial performance, external market and peer group practices, current compensation arrangements, internal pay equity considerations and long-term potential to enhance stockholder value. Particular factors considered by the Committee with respect to each element of executive compensation are discussed below.

Periodically the Committee retains independent compensation consulting firms (historically Towers Watson) to assist it in gathering comparison data and to provide it with information about trends in compensation among comparable companies based on factors such as market capitalization, annual revenues, earnings, service offerings, number of employees, and potential competition for talent or business. The Committee believes that comparing the compensation of each of the Company’s named executive officers with executives in comparable positions at these peer companies supports the Committee’s goal that the total compensation provided to the Company’s named executive officers is set at an appropriate level to attract, reward and retain top performers over the long term. In general, the Committee currently believes that compensation is competitive if it falls within +/- 15% of the median levels of peer company data provided by its compensation consultant, as discussed below. Where peer company data is not available, the Committee reviews individual responsibility and performance, prior compensation, external market and competitive practices (including available general industry executive compensation data), and internal pay equity considerations when setting an executive officer’s compensation.

The Committee assesses each element of the compensation program within the whole, however, and may target certain elements of executive compensation at different levels (i.e. higher or lower than +/- 15% of the median levels of peer companies) depending on the Company’s current goals, individual achievement and internal pay equity considerations, as discussed in more detail below. Changes to different elements may result in total target compensation being higher or lower than +/- 15% of the median levels of the peer company data.

The Committee engaged Towers Watson in 2011 to review and revise the Company’s competitive peer group and generally to update its review and competitive assessment of the Company’s executive compensation program based on the updated peer group and in light of the proposed merger with LoopNet, Inc. (“LoopNet”), which was completed in April 2012. The Committee engaged Towers Watson again in 2013 to review and revise the Company’s competitive peer group, to update its review and competitive assessment of the Company’s executive compensation program based on the updated peer group, and to identify potential modifications to the executive compensation program based on market practices and trends and in response to stockholder concerns raised in connection with the 2013 annual stockholders' meeting, the Company’s business priorities, structure and growth expectations, and to address stockholder concerns. The Committee’s decisions regarding executive compensation for 2013, including executives’ long-term incentive or equity compensation for 2013, and certain program changes were based on Towers Watson’s recommendations resulting from both its 2011 and 2013 engagements.

Towers Watson reported directly to the Committee through its chair when performing the executive compensation studies and, at the direction of the Committee chair, also worked directly with the Company’s management to develop materials and proposals with respect to named executive officer compensation. In the future, the Committee plans at

its discretion to retain Towers Watson or another consulting firm from time to time to update or perform new studies to be used in connection with its executive compensation decisions.

The following is the list of peer companies selected and approved by the Committee in 2012, based upon the recommendation of Towers Watson from its 2011 study, as comparable to the Company in terms of size (including revenues, earnings and market capitalization), business model and financial performance. Within the selected peer group, based on the 2011 study, the Company fell near the 40^th percentile in terms of revenues, 50^th percentile in terms of earnings and 70^th percentile in terms of market capitalization. The peer group from the 2011 Towers Watson study included a smaller number of companies than in the past (reduced from 29 in the previous study to 15) as is more customary and which is believed to better reflect a set of more comparable peers taking into account the proposed merger with LoopNet, which was completed in April 2012.

The 2011 Towers Watson study also considered general industry executive compensation data from Towers Watson’s 2011 Executive Compensation Database, size-adjusted based on CoStar’s estimated annual revenues. The Committee was not made aware of the names of the companies included in Towers Watson’s general industry executive compensation data. Where available, the Committee utilized peer company data as the primary competitive benchmark when evaluating the executives’ compensation, including base salaries, cash incentives, and long-term equity incentive awards, as the peer company data reflects companies that are believed to be more similar to CoStar in terms of size, business model and financial performance. In those cases where peer data was unavailable, the Committee took into account individual responsibility and performance, previous cash compensation and equity awards to the respective named executive officers, external market and competitive practices (including available general industry executive compensation data), as well as internal pay equity considerations.

In connection with its engagement in 2013, Towers Watson recommended a revised list of peer companies to be used when evaluating executives’ 2013 equity grants and the performance measures used in connection with, executives’ 2013 equity grants, as well as potential changes to the 2014 executive compensation program. The following is the list of peer companies selected and approved, based upon the recommendation of Towers Watson. Towers Watson’s recommended peer companies culminated from review of peer companies included in the Internet Software & Services GICS code (including peer companies used previously and peers selected by proxy advisors), to which size screening criteria were applied. Towers Watson screened these peers by considering companies with revenue, net income, EBITDA, market cap and/or number of employees between .5x and 3x of CoStar’s. The potential peer list was further refined based on the number of criteria met through the size screening and the business model or focus (business analytics software products and services). After its review, Towers Watson recommended removing five companies, four due to relatively low market cap and one because it was larger than the Company and does not fall within the same GICS code. Towers Watson recommended adding six companies which are in the same GICS code and satisfied at least three of the five size screening criteria. Within the selected peer group, the Company fell near the 35^th percentile in terms of revenues, 60^th percentile in terms of earnings and 90^th percentile in terms of market capitalization.

The 2013 Towers Watson study also considered general industry executive compensation data and high technology long-term incentives data from Towers Watson’s 2013 executive compensation database, aged to January 1, 2014 using a 3% update factor and size-adjusted based on CoStar’s estimated annual revenues. The Company was not made aware of the names of the companies included in Towers Watson’s general industry executive compensation data or in the high technology long-term incentive data.

ELEMENTS OF COMPENSATION

Each year, the Committee approves a compensation arrangement for each of its named executive officers that specifies a named executive officer’s (i) base salary, (ii) annual cash bonus potential based on a percentage of base compensation subject to achievement of individual and corporate goals (or commissions in the case of Mr. Stanfill), and (iii) equity awards, including restricted stock that is granted based on achievement of corporate goals and stock options, both of which vest over time and/or in full after a specified period of time. Commencing 2014, the equity awards include a third component consisting of a restricted stock grant that vests based on achievement of pre-determined, objective goals over a multi-year period. Additionally, our U.S. named executive officers are eligible to receive Company-paid matching contributions to their 401(k) plan accounts, as well as health insurance and other welfare benefits that are generally available to the Company’s U.S. employees.



	Component	Role	How It’s Set/Links to Performance
FIXED	Base Salary	• To provide a stable, reliable monthly income • Set at levels that should comprise a low percentage of total compensation	• Reviewed annually in light of responsibilities, performance, internal pay equity, total compensation, market practices and advice of the Committee’s independent consultant
VARIABLE	Annual Cash Incentive Compensation	• To reward the achievement of annual financial goals and personal performance • Links compensation to performance since award amounts are determined after fiscal year end based on actual results	• Variable based on the Company’s corporate performance and achievement of individual goals for the fiscal year • Key metric for fiscal 2013: adjusted EBITDA
	Stock Options and Annual Performance-Based Restricted Stock	• To increase alignment with stockholders • Retains executive officers through multi-year vesting	• For the performance-based restricted stock awards: variable and based on our corporate performance; key metric for fiscal 2013 is non-GAAP net income; and payout range is 0-200% of target award based on achievement. • Aligns executive interests with those of stockholders as potential value of awards increases or decreases with stock price • Paid in stock options and restricted stock • Options and annual performance-based restricted stock vest over three-year period
	Performance Share Awards (new in 2014)	• To reward achievement of longer-term financial goals • To retain executives through three-year vesting period • Realized value attributable to three-year revenue growth performance achievement and relative total stockholder return	• Payout range is 0-200% of target award • Payout based on financial metric (aggregate three-year revenue) • Relative total stockholder return can modify the ultimate payout +/-20% • Vests based on achievement of a three-year aggregate revenue performance goal, subject to adjustment based on TSR
	Other Compensation	• To allow executive officers to participate in other employee benefit plans	• Executives may participate in all other CoStar compensation and benefit programs on the same terms as other employees, such as health and welfare benefit plans and 401(k) Plan

PERFORMANCE MEASURES AND TIME HORIZONS

We use a combination of metrics and time horizons to foster and reward performance. The following chart summarizes the relevant performance measures and time frames used for our variable pay elements.

2013 Base Salaries

Base salaries provide a minimum, fixed level of cash compensation for the named executive officers. Salary levels of the executive officers are reviewed annually by the Committee. In establishing salary levels, the Committee considers each executive’s individual responsibilities and performance, prior base salary and total compensation, the pay levels of similarly situated executives within the Company, market data on base salary and total compensation levels (including Towers Watson peer group and survey data) and current market conditions. In March 2013, the Committee reviewed the named executive officers base salaries and determined to increase salaries for 2013 for the named executive officers (other than Mr. Carchedi who was not included in the study) by 2.5% over their salaries for 2012, primarily to account for cost of living adjustments and to keep them competitive in the marketplace. The named executive officers (other than Mr. Carchedi) increased base salaries are all within +/- 15% of the median levels of the peer group as reflected in the 2011 Towers Watson study and/or survey data provided by the Towers Watson study (where available). Mr. Carchedi was not an executive officer when the 2011 Towers Watson study was prepared, and therefore was not included in that study. Mr. Carchedi was named an executive officer in September 2012 and was appointed Executive Vice President of Operations in early 2013. Mr. Carchedi received a 25% increase in his base salary in recognition of his new responsibilities as a result of his promotion and of his past performance and to account for internal pay equity considerations. The annual base salaries of our named executive officers effective as of March 11, 2013 were as follows:

DECISION SUPPORT

As the Committee made its fiscal 2013 compensation decisions, it was aware that 65% of the CoStar stockholders who voted on the advisory vote on NEO compensation at the 2013 Annual Meeting of stockholders had voted in favor of approving the Company’s executive compensation, and concluded that this level of approving votes suggested that the stockholders generally supported the Committee’s approach but that some stockholders desired changes in the executive compensation program and corporate governance processes.

Andrew C. Florance	CEO & President	$	563,750
Brian J. Radecki	CFO	$	358,750
Francis A. Carchedi	Executive Vice President, Operations	$	300,000

2013 Annual Cash Incentive Program

The Committee administers an annual cash incentive program under which the Company’s named executive officers may earn a cash incentive bonus based on a fixed target percentage of base salary during the fiscal year, if individual and corporate performance objectives for the fiscal year are achieved. At the beginning of each year, the Committee establishes individual goals for each named executive officer, other than the Chief Executive Officer, based upon recommendations from our Chief Executive Officer, as well as Company financial goals that apply to all named executive officers that are based upon recommendations from our Chief Executive Officer and our Chief Financial Officer. The Committee determines the target percentages of base pay for each named executive officer based on market and competitive conditions, peer company practices, and internal pay equity considerations. The Committee also determines the weighting of the various individual and Company financial goals, based upon position and functional accountability and responsibility, as well as recommendations from our Chief Executive Officer. The target percentages and weighting of the various individual and Company financial goals may vary among the named executive officers and are subject to change from year to year. The Committee seeks to establish performance goals that are challenging but realistic given the expected operating environment at the time they are established. These performance goals are intended to focus named executive officers on achieving the Company’s financial and operating goals. After the completion of each year, the Committee reviews individual and Company performance to determine the extent to which the goals were achieved and the actual cash bonuses to be paid to the named executive officers.

In the Committee’s view, the use of annual performance-based cash incentive bonuses creates a direct link between executive compensation and individual and corporate performance. Therefore, the annual performance-based cash incentive bonus is generally divided into two components, one tied to corporate performance and one tied to individual performance. As discussed in greater detail below, the Committee sets a threshold, target and maximum award for the corporate performance objectives. Accordingly, the annual cash incentive plan provides each named executive officer with the potential to earn awards up to two times the amount of their target award value for exceptional performance as measured against metrics and goals, each of which is discussed below. If the maximum is achieved, the named executive officers receive 200% credit for the corporate performance portion of the award. If the target is achieved, the named executive officers receive 100% credit for the corporate performance portion of the award. If the threshold level of corporate performance is not reached, the executive officer does not receive any amount in respect of that portion of the award. Achievement of the individual performance goals are subjective and executives can receive between 0 and 200% credit for that portion of the award.

The Committee reviewed 2013 target and maximum award values in early 2013 and determined to increase the 2013 target and maximum award values for Mr. Carchedi in light of his promotion, increased responsibility and after taking into account internal pay equity considerations. The Committee reviewed and left unchanged Mr. Florance’s and Mr. Radecki’s target and maximum award values for 2013 based upon their individual responsibilities, competitive practices and internal pay equity considerations. Mr. Florance’s and Mr. Radecki’s 2013 target award values remained generally aligned with market common practice (within +/- 15% of the median level of the peer company data in the 2011 Towers Watson study). Mr. Carchedi was not an executive officer when the 2011 Towers Watson study was prepared, and therefore was not included in that study. The Committee determined to have Mr. Stanfill’s cash incentive for 2013 be based solely on his commission plan, which emphasizes, and centers the potential payouts on, the Company’s cross selling efforts, including sales of CoStar services to LoopNet customers and LoopNet services to CoStar customers. The Committee determined that Mr. Stanfill’s potential commission payments balance out his overall compensation package, and therefore, Mr. Stanfill is not eligible for a cash incentive award in 2013 apart from the commission plan.

Pursuant to her separation and release agreement dated October 2013, Ms. Kitchen is no longer eligible to receive any cash incentive or bonus payments for fiscal year 2013 or 2014. The following table shows each named executive officer’s fiscal 2013 potential award values at threshold, target and maximum, expressed as a percentage of his or her base salary.



Name	Title	Threshold		Target		Maximum
Andrew C. Florance	CEO & President	50.0	%	100.0	%	200.0	%
Brian J. Radecki	CFO	32.5	%	65.0	%	130.0	%
Francis A. Carchedi	Executive Vice President, Operations	32.5	%	65.0	%	130.0	%
John L. Stanfill⁽¹⁾	Sr. Vice President, Sales & Customer Service	—		—		—
Jennifer L. Kitchen⁽²⁾	Director, Research Integration	—		—		—


(1)	Mr. Stanfill’s incentive cash compensation for 2013 consists entirely of potential commission payments based on achievement of Company-based performance objectives described below.


(2)	Pursuant to her separation and release agreement dated October 2013, Ms. Kitchen is not eligible to receive any cash incentive or bonus payments for fiscal year 2013 or 2014 performance. The Committee had previously set Ms. Kitchen’s 2013 threshold award value at 20% of base salary, 2013 target award value at 40% of base salary and 2013 maximum award value at 80% of base salary.

Each named executive officer may earn an incentive bonus equal to, greater than or less than the target percentage of his or her base salary depending on whether the individual and the Company achieve the specified performance objectives. These objectives include individual qualitative performance goals (except for our Chief Executive Officer), as well as Company-wide financial goals. For 2013, the Committee initially selected Company-wide financial goals based on the Company’s achievement of: (1) an annual revenue target included in the Company’s 2013 operating plan approved by the Company’s Board at the beginning of 2013 (the “2013 Operating Plan”); and (2) an EBITDA target included in the 2013 Operating Plan. EBITDA is our GAAP-basis net income (loss) before interest, income taxes, depreciation and amortization. These financial goals were selected by the Committee because it believes that revenue and EBITDA are good measures of stockholder value.

After the 2013 annual meeting and conversations between the Company and representative stockholders, the Compensation Committee approved changes to the Company-wide financial goals in order to be responsive to stockholder concerns about use of the same performance metrics in the annual cash incentive and performance-based stock awards. The Committee replaced the revenue and EBITDA goals for the cash incentive plan with a single Company-wide financial goal based on the achievement of adjusted EBITDA included in the 2013 Operating Plan. Adjusted EBITDA is our GAAP-basis net income (loss) before interest, income taxes, depreciation and amortization, stock-based compensation expense, acquisition-related and integration-related costs, restructuring costs and settlements and impairments incurred outside our ordinary course of business. Adjustments made in 2013 are identified in the reconciliation of adjusted EBITDA to its GAAP-basis result, in Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the Commission on February 19, 2014. The Committee determined that adjusted EBITDA is also a good measure of stockholder value and use of this metric (which differs from the metrics used for the performance-based stock grants) avoids any potential for duplicative payouts to the named executive officers for the same areas of performance. In making the determination to move forward with a change to the financial goals, the Committee considered the fact that if it had retained the initial Company-wide revenue and EBITDA goals, the named executive officers would have received the same amount of compensation for their 2013 cash incentive (or credit for 200% achievement of the 2013 financial goals in either case) as shown in the table below.

2013 Annual Cash Incentive Awards – Financial Goal⁽¹⁾
(dollar amounts in millions)



Performance Metric (Revised)	Threshold Goal	Target Goal	Maximum Goal	2013 Actual
Adjusted EBITDA	$86.4	$108.0	$118.8	$136.8
Payout Percentage	50%	100%	200%	200%



Performance Metric (Original)	Threshold Goal	Target Goal	Maximum Goal	2013 Actual
Revenue	$399.8	$420.9	$429.3	$440.9
Payout Percentage	50%	100%	200%	200%
EBITDA	$46.7	$58.4	$64.2	$94.2
Payout Percentage	50%	100%	200%	200%

(1)

Named executive officers could receive between 0% and 200% credit for the Adjusted EBITDA component of their annual cash incentive award, depending upon actual Adjusted EBITDA achieved in 2013. Credit for performance between threshold and target and between target and maximum are determined by linear interpolation. No credit is given for performance below threshold and credit is capped at 200% of target. The percent credited for the Adjusted EBITDA component of the award (as shown in the table) is then multiplied by the weighting applicable to the respective component of the cash incentive award. Similar methodology applied to the metrics originally selected.

The individual performance goals established for the named executive officers, other than the Chief Executive Officer, at the beginning of 2013 are strategic and leadership goals tailored to the individual’s position and focused on the Company’s strategic initiatives. The individual goals assist the Committee in assessing the named executive officer’s individual performance in key areas that help drive the Company’s operating and financial results. The use of both individual and corporate goals advances the Company’s executive compensation philosophy that individual executives be held accountable for both their own individual performance as well as the Company’s performance. Based on peer data from past compensation consultant studies, which indicate that more commonly the chief executive officer’s annual incentive is tied solely to corporate results, the Committee determined that it is in the best interests of the Company to have our Chief Executive Officer’s annual incentive award based exclusively on the financial performance of the Company.

Performance goals and the weighting given to each may change in the Committee’s discretion from year to year. The measures and the relative weighting of individual and corporate financial performance goals for each of the named executive officers is reviewed by the Committee annually at the beginning of the respective year. The Chief Executive Officer proposes to the Committee for its consideration changes to the measures and the weighting of the performance goals based on the Company’s current strategic initiatives and goals. The weighting of the individual and corporate objectives for the named executive officers for 2013 is shown in the table below.

Individual Performance Goals for 2013 Annual Cash Incentive Awards

The 2013 individual performance goals and percentage of such goals achieved for Mr. Radecki and Mr. Carchedi are summarized in the table below. The Committee sets aggressive individual performance criteria for annual cash incentive awards that are challenging but realistic to achieve in order to motivate named executive officers to excel and perform at a high level and to focus on overall corporate objectives. The Committee intends to set the individual performance criteria for the annual cash incentive awards such that the relative difficulty of achieving the target level is consistent from year to year.



Name	Title	2013 Individual Goals	% of Goals Achieved
Brian J. Radecki	CFO	• Recruit, hire and retain key personnel • Manage the Company’s costs • Manage the Company’s indebtedness and related covenants • Facilitate the Company’s mergers and acquisitions activity • Facilitate and manage integration of acquired entities • Effectively communicate with the Company’s investor base and analysts • Manage the Company’s Securities and Exchange Commission filings and the annual audit	175%
Francis A. Carchedi	Exec. Vice President, Operations	• Support Chief Executive Officer and operations of the Company and its subsidiaries • Facilitate and manage integration of acquired entities and create efficiencies in operations • Project management for verticals	200%

2013 Performance Against Corporate and Individual Objectives

In February 2014, the Committee assessed the Company’s and each named executive officer’s achievement of the goals and targets for 2013. Information regarding the target percentages of base salary for each named executive officer’s 2013 cash incentive award, percentage of target achieved and actual 2013 cash incentive awards paid to each named executive officer, as well as the weighting of individual and financial performance goals for 2013, are shown in the table below. A description of 2013 performance compared to the corporate and individual goals follows the table.

2013 Annual Cash Incentive Awards



Name	Title	Weighting for Individual Goals	Weighting for Adjusted EBITDA Target	Target as a % of Salary	Percentage of Target Achieved	Actual Award as a % of Salary	Actual Cash Award ($)
Andrew C. Florance⁽¹⁾	CEO & President	—	100%	100%	200.0%	200.0%	$	1,127,500
Brian J. Radecki⁽²⁾	CFO	20%	80%	65%	195.0%	126.8%	$	454,716

John L. Stanfill⁽⁴⁾	Sr. Vice President, Sales & Customer Service	Not a participant in the annual incentive plan in 2013
Jennifer L. Kitchen⁽⁵⁾	Director, Research Integration	Not a participant in the annual incentive plan in 2013


(1)	As discussed above, Mr. Florance’s 2013 annual cash incentive award is based solely on corporate performance goals.


(2)	The weighting of the goals for Mr. Radecki was revised in 2013 to give more weight to the Company’s financial goals, which reflects the Company’s emphasis on overall earnings and Mr. Radecki’s role with respect to the operations of the Company as a whole.

(3)

The weighting of the goals for Mr. Carchedi was revised in 2013 to give substantial weight to the Company’s financial goals and to shift focus from individual goals which consisted of strategic and operational goals targeted to the Company’s growth and development in light of the merger and integration with LoopNet. The revised weighting reflects the Company’s emphasis on overall earnings and Mr. Carchedi’s increased role with respect to the operations of the Company as a whole.


(4)	As indicated above, the Committee determined that Mr. Stanfill’s potential commission payments, based on a percentage of the Company’s U.S. monthly net new subscription contracts, balance out his overall compensation package, therefore he is not eligible for a cash incentive award in 2013 apart from the commission plan.


(5)	Pursuant to her separation and release agreement dated October 2013, Ms. Kitchen is not eligible to receive a cash incentive or bonus payment for fiscal year 2013.

Commission Payments

Mr. Stanfill is entitled to receive monthly commissions based on a percentage of the Company’s U.S. monthly new subscription contract amounts net of cancellations. In early 2013, the Committee determined to restructure Mr. Stanfill’s commission plan to place greater focus on the Company’s cross selling efforts, including sales of CoStar services to LoopNet customers and LoopNet services to CoStar customers. As a result, the Committee determined to have Mr. Stanfill’s cash incentive for 2013 be based solely on his commission plan. Mr. Stanfill is not eligible for a cash incentive award in 2013 apart from the commission plan. The Committee determined that Mr. Stanfill’s potential commission payments balance out his overall compensation package. The commission payments provide incentive for Mr. Stanfill to continue to grow the Company’s business and generate revenues, and the rates of payment are set to provide challenging but achievable goals to motivate Mr. Stanfill to maintain his focus on sales of the Company’s subscription-based services, the Company’s primary source of revenue, as well as cross selling the Company’s services. The Company is not disclosing the specific commission rates because they are based on key operational objectives that would signal the Company’s strategic direction and also could be used by competitors to target recruitment of Mr. Stanfill. The total commission payments paid to Mr. Stanfill for 2011, 2012 and 2013 are shown in the Summary Compensation Table on page 56 of this Proxy Statement.

Equity Incentive Plan

The Committee has designed the executive equity incentive compensation program with the intent of aligning executive incentives with long-term stockholder value and with a view toward executive retention. The Committee believes that equity-based compensation and executive ownership of the Company’s stock help support the Committee’s goal that the Company’s named executive officers have a continuing stake in the long-term success of the Company.

Each named executive officer is eligible to receive equity awards under the Company’s 2007 Stock Incentive Plan, as amended (the “2007 Plan”). The Committee generally grants time-based restricted stock and/or stock options to each executive when he or she joins the Company or upon promotion to an executive position as an incentive to accept employment and become a member of the Company’s executive team. As set forth in more detail below, the Committee currently also makes annual grants of equity awards as part of the executive compensation program. Over the past few years, those grants have consisted of restricted stock and stock options. In response to, and in support of, stockholders’ belief that a greater portion of the equity awards should be long-term performance awards, commencing in 2014, the Committee enhanced the program so that the restricted stock portion of the annual grants consist of restricted stock subject to time-based vesting and a performance-based grant of restricted stock which vests based on achievement of a three-year cumulative revenue goal and is subject to adjustment based on the Company’s total stockholder return over the three-year performance period. The three-year performance shares provide a long-term or multi-year performance measurement encouraging executives to achieve sustained growth. Under the program, target award values are determined at the time of grant, and the amount of time-based restricted stock actually granted each year is determined based on the Company’s performance during the prior year.

The Committee decided to grant a mix of equity awards because each type of award helps achieve some of the objectives of the executive compensation program.


•	The Committee believes that options have a performance-based element because the option holder realizes value only if the stockholders also realize value – if the price of the Company’s common stock has increased from the grant date at the time the option is exercised.


•	In contrast, restricted stock awards have value when they vest regardless of the stock price, so they have retention value even if the Company’s common stock price declines or stays flat.


•	Grants of performance shares that vest based on achievement of a long-term performance goal also provide a long-term or multi-year performance measurement encouraging executives to achieve sustained growth, increasing executives’ focus on longer-term financial goals and further linking executives’ interests with those of our stockholders.

Stock options motivate executive officers by providing greater potential upside while restricted stock awards promote executive retention, focus executives’ attention on total stockholder return and balance the Company’s compensation program. The Committee believes that the use of multi-year vesting periods for equity awards (for both stock options and restricted stock) emphasizes a longer-term perspective and therefore encourages executive retention. Under the current program, all stock option and restricted stock awards issued to the named executive officers that vest over time are subject to a three-year vesting period from the date of grant.

The value of the annual equity compensation awards granted to our named executive officers is based on a target award dollar amount and varies among named executive officers by position depending upon individual responsibility and performance, external market and peer group practices, internal pay equity considerations, and, with respect to the time-based restricted stock awards, achievement of the performance criteria as described below. Consistent with its determinations for executive compensation generally, the Committee has generally set the aggregate target equity compensation within +/- 15% of the median levels of the peer company data provided by its compensation consultant, where available, but retains discretion to set target award levels based on the considerations set forth above.

Overview of Long-Term Incentive Components



	Stock Options	Performance-Based Restricted Stock	Performance Share Plan
New Component of Plan?	No	No	Yes - Annual grant (commencing 2014)
% of Target Value (commencing 2014)	40%	40%	20%
Grant Determination Process	Target value ranges by position	Grant pools set by previous year’s performance (same as current program)	Target value ranges by position
Vesting / Performance Period	3-year vesting (same as current program)		3-year performance cycle with vesting upon achievement and Compensation Committee certification
Performance Goals	N/A	Change from revenue and EBITDA in 2012 to non-GAAP net income in 2013; performance scale maximum of 200%	Multi-year goals - 3-year aggregate revenue, plus relative total stockholder return kicker (+/- 20% payout modifier)

To illustrate performance periods and grant timing, we have provided an overview:

Target Equity Incentive Awards Granted in 2013

After review of the executive compensation program in early 2013, the Company’s goals (including linking executive incentives with long-term stockholder value), peer data (where available), previous equity awards to the respective named executive officers, the total mix of compensation for each individual, individual performance and internal pay equity and competitive considerations, the Committee determined to increase the annual, long-term equity incentive target award values for Messrs. Florance and Radecki and to leave the annual, target award values constant for Mr. Stanfill and Ms. Kitchen. Mr. Florance’s and Mr. Radecki’s target award values for the equity compensation component of their compensation for 2013 were set within +/-15% of the median peer company data. Where available, the Committee utilized peer company data from the Towers Watson study as the primary competitive benchmark when evaluating the executives’ target award values, as the peer company data reflects higher growth companies believed to be more similar to CoStar.

In those cases where peer data was unavailable, the Committee took into account previous equity awards to the respective named executive officers as well as internal pay equity considerations. No peer company data was available with respect to long term equity incentive compensation for Mr. Carchedi, our Executive Vice President of Operations who was not an executive officer when the 2011 Towers Watson study was prepared, or Ms. Kitchen, our Director, Research Integration. The Committee set Mr. Carchedi’s target award value in recognition of his new responsibilities as a result of his promotion to Executive Vice President of Operations and to account for internal pay equity considerations. When determining Mr. Stanfill’s and Ms. Kitchen’s target award values for the equity compensation component for 2012 performance (granted in 2013), the Committee took into account previous equity awards, internal pay equity considerations and their overall compensation packages. As a result of the Committee’s freezing of target award values in early 2012 and the fact that Mr. Stanfill’s target award value for 2012 performance (granted in 2013) remained constant while peer company target award values increased for equivalent positions as indicated by the 2011 Towers Watson study, Mr. Stanfill’s target award value for the equity compensation component for 2012 performance falls significantly below the median level of the peer company data from the 2011 Towers Watson study.

The performance measures selected by the Committee for determination of the restricted stock award portion of the named executives’ equity compensation for 2012 performance were revenue and EBITDA and each is weighted equally. The Committee chose these metrics for the plan because of its belief that they were the most relevant measures of the Company’s financial performance at the time and are a good measure of stockholder value. Once the achievement level of each performance target and the total amount of the award for each named executive officer has been determined by the Committee, the number of shares of restricted stock actually granted to a named executive officer is determined using the fourth quarter average daily closing price of the Company’s common stock and approved by the Committee. The grant date of the annual performance-based restricted stock awards is the date that the Committee approves the grants. These awards are granted under our 2007 Plan and they vest in equal installments on the first three anniversaries of the date of grant. Grants of performance-based restricted stock are accounted for using the fair market value of such stock on the date of grant.

The Committee supplements the named executive officers’ annual performance-based restricted stock award with an annual award of stock options. Annual option grants are also based on the target award values determined as of the date of grant and vest pro rata over three years. The value actually awarded to each named executive officer is converted to the number of options based on Towers Watson’s recommended value per option calculated using the Black-Scholes model, and may be updated from time to time. The exercise price for each option is equal to the closing price of the Company’s common stock on the date of grant, which is the date of approval by the Committee.

The Committee approved the following target award values for the annual equity compensation awards, including the performance-based restricted stock awards granted in 2013 for 2012 performance and the annual stock option awards granted in 2013.



Name	Title	Performance-Based Restricted Stock Target Award Values	Annual Option Award Values	Aggregate Annual Target Award Values
Andrew C. Florance	CEO & President	$1,400,000	$1,400,000	$2,800,000
Brian J. Radecki	CFO	$335,000	$335,000	$670,000
Francis A. Carchedi	Exec. Vice President, Operations	$300,000	$300,000	$600,000
John L. Stanfill	Sr. Vice President, Sales & Customer Service	$250,000	$250,000	$500,000
Jennifer L. Kitchen	Director, Research Integration	$125,000	$125,000	$250,000

2012 Performance-Based Restricted Stock Awards Granted in 2013

On March 11, 2013, the Committee approved and awarded each named executive officer a grant of restricted stock, the size of which was based on the target award values set forth above and achievement of specified Company financial goals for 2012 performance (the “2012 Performance-Based Stock Awards”). The revenue and EBITDA goals established by the Committee are equally-weighted and the actual value of the 2012 performance-based stock awards granted to named executive officers was based on the Company’s achievement of these goals. Each named executive officer had the potential to earn up to two times his or her annual performance-based restricted stock target award value for exceptional performance as measured against the pre-established metrics and goals.

Named executive officers could receive between 0% and 200% credit for the revenue and EBITDA components of their annual performance-based stock award, depending upon actual revenue and EBITDA achieved in 2012. Credit for performance between threshold and target and between target and maximum are determined by linear interpolation. No credit is given for performance below threshold and credit is capped at 200% of target. The percent credited for the revenue and EBITDA components of the award (as shown in the table) is then multiplied by the weighting (50%) applicable to the respective component of the performance-based restricted stock award.

For 2012 performance, each named executive officer received 200.0% of his or her target award value. The 2012 Performance-Based Stock Awards were granted on March 11, 2013, and the stock award value earned by each named executive officer is shown in the table below. For additional information, see the “Grants of Plan-Based Awards” table on page 58 of this Proxy Statement.

2013 Stock Option Awards

On March 11, 2013, the Committee awarded the named executive officers stock options. The number of shares of common stock underlying the option awards granted to named executive officers was based on the award values described above. The table below sets forth the option award values and the number of shares of common stock underlying each option award for the option grants to the named executive officers granted in March 2013.

The number of shares granted is determined by dividing the option award value by Towers Watson’s recommended value per option calculated using the Black-Scholes model, rounded up to the nearest 100 shares. The amounts reported in this table under “Option Award Values” differ from the grant date fair values for these awards reported in the “Summary Compensation Table” and the “Grants of Plan-Based Awards” table on pages 56 and 58, respectively, of this Proxy Statement.

Target Equity Incentive Awards Granted in 2014

The Committee elected to review the target award values in early 2014 in advance of awarding the annual performance-based restricted stock awards in 2014 for 2013 performance and the annual stock option awards in 2014. After this additional review of the Company’s goals (including linking executive incentives with long-term stockholder value), previous equity awards to the respective named executive officers, the total mix of compensation for each individual, internal pay equity and competitive considerations, and the 2013 Towers Watson study, the Committee determined to increase the target award values for all named executive officers in recognition of their responsibilities and performance. In addition, in response to conversations between the Company and representative stockholders during 2013 and specific issues discussed concerning the lack of a multi-year performance measurement within the equity program, based on recommendations received from Towers Watson, the Committee revised the equity program, so that the target value of the awards are made up of 40% options, 40% restricted stock granted based on achievement of annual financial performance objectives and subject to a three-year vesting term, and 20% restricted stock subject to vesting based on a three-year pre-determined performance objective and adjustment based on achievement of total stockholder return relative to TSR of companies within the Russell 1000.

•	40% options;


•	40% performance-based restricted stock granted based on achievement of non-GAAP net income performance objectives and subject to a three-year vesting term; and


•	20% performance shares earned based on a three-year aggregate revenue performance objective and adjustment based on achievement of total stockholder return relative to TSR of companies within the Russell 1000.

In addition, after the 2013 annual meeting and conversations between the Company and representative stockholders, the Compensation Committee approved changes to the Company-wide financial goals in order to be responsive to stockholder concerns about use of the same performance metrics in the annual cash incentive and performance-based stock awards. The Committee replaced the revenue and EBITDA goals for the restricted stock awards based on 2013 performance with a single Company-wide financial goal based on the achievement of non-GAAP net income included in the 2013 Operating Plan. Non-GAAP net income is our GAAP-basis net income (loss) before stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, settlement and impairment costs incurred outside our ordinary course of business as well as purchase amortization and other related costs and an assumed provision for income taxes. Adjustments made in 2013 are identified in the reconciliation of non-GAAP net income to its GAAP-basis result in Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the Commission on February 19, 2014. The Committee determined that non-GAAP net income avoids any potential for duplicative payouts to the named executive officers for the same areas of performance. In making the determination to move forward with a change to the financial goals, the Committee considered the fact that if it had retained the initial Company-wide revenue and EBITDA goals for 2013 performance, the named executive officers would have received the same aggregate equity award value (or credit for 200% achievement of the financial goals in either case), as shown in the table below.

2013 Performance-Based Stock Awards – Financial Goal⁽¹⁾
(dollar amounts in millions)



Performance Metric (Revised)	Threshold Goal	Target Goal	Maximum Goal	2013 Actual
Non-GAAP Net Income	$44.4	$55.5	$61.1	$72.6
Payout Percentage	50%	100%	200%	200%
Performance Metric (Original)	Threshold Goal	Target Goal	Maximum Goal	2013 Actual
Revenue	$399.8	$420.9	$429.3	$440.9
Payout Percentage	50%	100%	200%	200%
EBITDA	$46.7	$58.4	$64.2	$94.2
Payout Percentage	50%	100%	200%	200%

(1)

Named executive officers could receive between 0% and 200% credit for the non-GAAP net income goal, depending upon actual non-GAAP net income achieved in 2013. Credit for performance between threshold and target and between target and maximum are determined by linear interpolation. No credit is given for performance below threshold and credit is capped at 200% of target. Similar methodology applied to the metrics originally selected.

The chart below sets forth the target award values for the annual equity compensation awards, including the annual stock option awards granted in 2014, the performance-based restricted stock awards granted in 2014 for achievement of 2013 non-GAAP net income that vested ratably over three years, and the performance-based grant of restricted stock, which vests based on achievement of a three-year cumulative revenue goal and is subject to adjustment based on the company’s total stockholder return over the same three-year period. The value of performance-based restricted stock ultimately awarded to our named executive officers in early 2014 for 2013 performance was determined based upon achievement of non-GAAP net income as described below. Each named executive officer had the potential to earn up to two times his or her annual performance-based restricted stock target award value for exceptional performance as measured against the goal.



Name	Title	Annual Option Target Award Values	Annual Performance-Based Restricted Stock Award Values	3-year Performance Stock Award Values	Aggregate Annual Target Award Values
Andrew C. Florance	CEO & President	$1,360,000	$1,360,000	$680,000	$3,400,000

2013 Performance-Based Restricted Stock Awards Granted in 2014

On February 28, 2014, the Committee approved and awarded each named executive officer a grant of restricted stock, the size of which was based on the target award values set forth above and achievement of non-GAAP net income for 2013 (the “2013 Performance-Based Stock Awards”).

For 2013 performance, each named executive officer received 200.0% of his or her target award value. The 2013 Performance-Based Stock Awards were granted on February 28, 2014, and the stock award value earned by each named executive officer is shown in the table below. As these awards were granted in early 2014, the grant date fair values of these awards are not included in the Summary Compensation Table or Grants of Plan-Based Awards Table below, but will be reflected in next year’s proxy statement.

OTHER COMPENSATION POLICIES AND PRACTICES

EXECUTIVE STOCK OWNERSHIP POLICY

The Company believes that its executive officers should have a significant financial stake in the Company. To better align the interests of our executive officers with those of our stockholders, in early 2014, the Compensation Committee adopted an Executive Stock Ownership Policy. Executive officers are expected to own shares of the Company’s common stock as follows:



Name	Shares
CEO & President	Required to own shares with a value equal to 6x annual base salary
Other Executive Officers	Required to own shares with a value equal to 2x annual base salary

Shares subject to unvested or unexercised equity awards are not considered owned by the executive for purposes of the policy. The current executive officers have until December 31, 2019 to meet the ownership requirements.

EQUITY GRANT PRACTICES

The Company does not have any program, plan or practice to time equity awards in coordination with the release of material non-public information, nor does the Company time the release of material nonpublic information for the purpose of affecting the value of executive compensation.

RECOUPMENT (OR “CLAWBACK”) POLICY

In early 2014, the Compensation Committee approved a recoupment (“clawback”) policy. In the event of a restatement due to material non-compliance with financial reporting requirements, the Board is required to review cash incentive payments to executive officers and all performance-based equity awards issued to executive officers during the three years prior to the date the Company determines the restatement is required. If the Board determines that the payments or grants would have been lower had they been determined or calculated based on the restated results, the Board will, to the extent permitted by governing law, seek to recoup for the benefit of the Company the value of such payments made to executive officers whom the Board determines engaged in willful misconduct or gross negligence.

ANTI-HEDGING POLICIES

Pursuant to the Company’s insider trading policy, the Company does not permit directors, officers or other employees to engage in speculative or short-term financial activities involving the Company’s stock or derivatives based on the Company’s securities without the consent of the Company’s compliance officer. In addition, the Company does not generally allow any such activities or other hedging activities by its executive officers or directors absent an extraordinary circumstance.

TERMINATION AND CHANGE OF CONTROL PAYMENTS

Except for Mr. Florance, who has termination provisions in his employment agreement, the Company is not obligated to provide significant severance or termination payments to named executive officers. In 2008, the Company adopted a company-wide severance plan that provides payments that do not discriminate in scope, terms or operation in favor of executive officers of the Company and that are available generally to all salaried employees, including the named

executive officers. Pursuant to the Company’s severance policy, in recognition of their service to the Company, full-time staff who are part of a position reduction may receive severance pay equal to two weeks current base pay for the first year or less of employment, plus one week current base pay for each completed additional year of continuous service (up to a 16-week maximum payout) in exchange for a full release of claims. All Company employees are employed at will and, unless specified otherwise by an employment agreement, CoStar is not liable to pay severance but has chosen to adopt this severance policy to apply only in limited circumstances. The Company may choose to pay severance outside of the severance policy in its sole discretion and may amend, alter or discontinue the severance policy at any time.

Similarly, except for Mr. Florance, who negotiated change of control provisions in his employment agreement, the Company does not provide significant cash payments to named executive officers upon a change of control or other similar significant corporate event. However, in order to protect the rights granted under the Company’s 1998 and 2007 stock incentive plans, the form of grant agreement provides for acceleration of vesting of stock and option grants and rights to exercise stock options upon certain significant events, including a change of control, liquidation or dissolution of the Company or the sale or disposition of all or substantially all of the Company’s assets (except in the event that the awards are assumed or substitute grants are awarded pursuant to the terms of the grant). Those rights do not discriminate in scope, terms or operation in favor of named executive officers of the Company and are available generally to all employees who participate in those plans, including the named executive officers.

Details of the potential termination payments for Mr. Florance, of the rights triggered under the 1998 and 2007 stock incentive plans in the case of a significant corporate event and potential payments under the Company-wide severance policy are set out below in the section entitled “Potential Payments Upon Termination or Change of Control” beginning on page 62 of this Proxy Statement.

POLICY ON DEDUCTIBILITY OF COMPENSATION

Section 162(m) of the Internal Revenue Code disallows the deduction of compensation paid by a public company to its Chief Executive Officer and each of the other three most highly compensated executive officers (not including the Company’s Chief Financial Officer) that exceeds $1 million. Compensation that is considered “performance-based” is excluded from the $1 million limit if, among other requirements, the compensation is payable only upon attainment of pre-established, objective performance goals under a plan approved by the stockholders. The CoStar Group, Inc. 2007 Stock Incentive Plan, as amended, has been structured so that stock options, stock appreciation rights and certain restricted stock and restricted stock unit awards may qualify as “performance-based” compensation under Section 162(m). In addition, bonuses payable under the CoStar Group, Inc. 2011 Incentive Bonus Plan are intended to qualify as “performance-based” compensation under Section 162(m). The rules and regulations promulgated under Section 162(m) are complicated, however, and subject to change from time to time, sometimes with retroactive effect. In addition, a number of requirements must be met in order for particular compensation to so qualify. As such, there can be no assurance that any compensation awarded or paid by the Company will be fully deductible under all circumstances. Furthermore, while the Committee may consider tax deductibility as one of the factors in determining executive compensation, to retain maximum flexibility in designing compensation programs that meet the Committee’s stated objectives, the Committee may not necessarily limit or structure compensation so that it is deductible under Section 162(m).

NARRATIVES TO SUMMARY COMPENSATION TABLE AND GRANTS OF PLAN-BASED AWARDS TABLE

EMPLOYMENT AGREEMENTS AND ARRANGEMENTS

We have an employment agreement with Mr. Florance, and we have at will employment terms with Mr. Radecki, Mr. Carchedi, Mr. Stanfill and Ms. Kitchen. Our employment agreement with Mr. Florance became effective as of January 1, 1998. All employees, including our named executive officers, are required to execute terms and conditions of employment, which state that employment is at will and set forth restrictive covenants, including duties of confidentiality, non-solicitation of customers and employees and non-competition. Mr. Radecki’s current employment terms became effective December 1, 1997. Mr. Carchedi’s current employment terms became effective June 4, 2009. Mr. Stanfill’s current employment terms became effective April 28, 2001. Ms. Kitchen’s current employment terms became effective March 6, 2001.

CHIEF EXECUTIVE OFFICER EMPLOYMENT AGREEMENT

Pursuant to his employment agreement, Mr. Florance is entitled to receive base salary, an annual cash bonus, six weeks of paid vacation per year, the same health insurance, accident and disability insurance, life insurance, and other fringe benefits provided to most senior executives of the Company, and additional term life insurance coverage not to exceed $1 million (at a cost to the Company not to exceed $2,000 per year), payable as designated by Mr. Florance. Mr. Florance’s employment agreement automatically renews for successive one-year terms unless either the Company or Mr. Florance provides the other with written notice of termination at least three months prior to the end of the then-current term.

Pursuant to his employment agreement, Mr. Florance is subject to confidentiality and non-compete restrictive covenants. The non-compete restrictions apply during the term of the agreement, any period of time during which he remains employed with the Company “at will” and through the second anniversary of the date of his termination.

EQUITY AWARDS

All grants of equity awards made in 2013 were made under the Company’s 2007 Plan. In April 2007, the Company’s Board adopted the 2007 Plan, subject to stockholder approval. Stockholders approved the 2007 Plan in June 2007, an amendment to the 2007 Plan in June 2010, which increased the number of authorized shares that can be issued under the 2007 Plan by 1,300,000 shares; an amendment to the 2007 Plan in June 2011, which increased the Tax Code limit on the number of shares of common stock that may be granted under the 2007 Plan to any one participant during a calendar year; and an amendment to the 2007 Plan in June 2012, which increased the number of authorized shares that can be issued under the 2007 Plan by 900,000 shares. 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 remained available for issuance pursuant to new awards under the 1998 Plan.

Stock options and restricted stock granted to named executive officers in 2013 and restricted stock granted in 2014 for performance in 2013, in each case pursuant to the named executive officers’ annual equity incentive grants, vest in equal installments over the first three anniversaries following the date of grant, except for grants of restricted stock subject to vesting based on pre-determined performance objectives which vest upon achievement of those objectives. For a description of the criteria applied in determining the number of shares of restricted stock awarded in 2013 and 2014 for performance in 2012 and 2013, respectively, see “Compensation Discussion and Analysis–Equity Incentive Plan” above. For a discussion of the effect of a change of control on outstanding restricted stock and option awards, see “Potential Payments Upon Termination or Change of Control–Change of Control Provisions under the Company’s 1998 and 2007 Plans” below. For a discussion of the effect of Mr. Florance’s termination on his outstanding equity awards, see “Potential Payments Upon Termination or Change of Control–Termination and Change of Control

Provisions pursuant to Employment Agreements” below. Under the 2007 Plan, recipients of restricted stock are entitled to receive all dividends and other distributions, if any, paid with respect to the common stock. The Compensation Committee will determine if any such dividends or distributions will be automatically reinvested in additional shares of restricted stock and subject to the same restrictions as the restricted stock or whether the dividend or distribution will be paid in cash.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

This section discusses the incremental compensation that would be payable by the Company to each named executive officer in the event of a change of control of the Company or a termination of the named executive officer’s employment with the Company for various reasons described below, sometimes referred to herein as a “triggering event.” In accordance with applicable SEC rules, the following discussion assumes that the triggering event in question — the change of control, termination of employment, death or disability — occurred on December 31, 2013, the last business day of 2013.

Pursuant to applicable SEC rules, the analysis contained in this section does not consider or include payments made to a named executive officer with respect to contracts, agreements, plans or arrangements to the extent they do not discriminate in scope, terms or operation, in favor of executive officers of the Company and that are available generally to all salaried employees.

The actual amounts that would be paid upon a named executive officer’s termination of employment or change of control can only be determined at the time of the applicable event. Due to the number of factors that affect the nature and amount of any benefits provided upon the events discussed below, any actual amounts paid or distributed may be higher or lower than reported below. Factors that could affect these amounts include the timing during the year of any such event and the Company’s stock price.

Termination and Change of Control Provisions pursuant to Employment Agreements

Mr. Florance

The Company is permitted to terminate Mr. Florance’s employment at any time, without “cause”, upon 60 days written notice, and Mr. Florance may voluntarily terminate his employment for “good reason” upon at least 60 days written notice. “Cause” is defined as (a) a material failure by Mr. Florance to perform his duties, which remains uncured for 60 days after written notice of the failure is provided by the Company, (b) Mr. Florance being convicted of a felony or pleading nolo contendre to a felony, or (c) any other willful act or omission by Mr. Florance which materially harms the financial condition or business reputation of the Company. “Good reason” is defined as (a) requiring Mr. Florance to relocate more than 45 miles from his current principal office, (b) Mr. Florance ceasing involuntarily to be Chief Executive Officer of the Company or being required to perform duties that are materially inconsistent with those normally performed by a chief executive officer, (c) the Company materially reducing the nature of his authority and duties, (d) requiring Mr. Florance to report to someone other than the Board, (e) the Company materially breaching its obligations under his employment agreement, which remain uncured for 90 days after written notice is provided by Mr. Florance to the Company, or (f) an acquisition or change of control of the Company occurring and Mr. Florance terminating his employment within one year after such event. For these purposes, an acquisition or change of control means (i) the acquisition of beneficial ownership of more than 50% of the outstanding common stock of the Company, (ii) election or appointment as directors comprising one-half or more of the Board of persons who were not nominated, recommended or appointed by the Company’s incumbent Board, (iii) the Company entering into a merger pursuant to which it is not the surviving entity, or (iv) sale by the Company of all or substantially all of its assets.

In the event that the Company terminates Mr. Florance’s employment without cause or if he terminates his employment for good reason, Mr. Florance is entitled to receive his base salary for one year payable in installments in accordance with the Company’s payroll practices, his bonus for the year in which the termination occurred, the immediate vesting of all of his unvested stock options and a gross-up payment, if any, to cover any taxes assessed under Section 4999 of the Tax Code. Upon termination by the Company without cause or by Mr. Florance for good reason, all of his unvested stock options will become immediately exercisable and he will have 180 days to exercise all vested options. If all or any portion of Mr. Florance’s stock options cannot be accelerated under the terms of the applicable stock incentive plan, Mr. Florance is entitled to receive cash consideration in lieu of acceleration for each share underlying that portion of his stock options that cannot be so accelerated equal to the excess (if any) of the highest closing price of the Company’s common stock during the 180 days following the executive's date of termination (or, if the Company is no longer publicly traded as of the date of termination, the per-share price in connection with the transaction(s) that resulted in the Company no longer being publicly traded) over the exercise price of such option.

Mr. Florance’s employment agreement also provides that in the event of his termination due to his disability or death, he (or his estate) would be entitled to receive (i) a prorated portion of his unvested stock options due to vest during the calendar year of his disability or death, and (ii) a prorated share of his bonus for the year of his disability or death. In the event of termination due to disability or his death, Mr. Florance (or his estate) would have one year to exercise all vested options. For the purposes of this analysis, which assumes a triggering event on December 31, 2013, he (or his estate) would be entitled to the full amount of his bonus for 2013.

Mr. Florance also has the right at any time to terminate his employment without good reason upon 180 days written notice to the Company, and the Company has the right at any time to terminate Mr. Florance for cause. In either such event, Mr. Florance would not be entitled to any base salary or fringe benefits for any period after termination, and he would forfeit any unvested stock options and his right to participate in the Company’s cash incentive program.

Others

Except as may be provided to all employees of the Company generally and as provided pursuant to the Company’s stock incentive plans (as described below), Mr. Radecki, Mr. Carchedi, Mr. Stanfill and Ms. Kitchen are not entitled to any post-employment compensation if their employment is terminated without cause.

Change of Control Provisions under the Company’s 1998 and 2007 Plans

Pursuant to the Company’s 1998 Plan and 2007 Plan and related award agreements, upon a change of control, all options will immediately vest and all restrictions on stock grants will lapse. For purposes of the stock incentive plans, a “change of control” means: (a) acquisition by a third party of more than 80% of the undiluted total voting power of the Company's then outstanding securities eligible to vote to elect members of the Board, (b) consummation of a merger or consolidation of the Company into any other entity, unless the holders of the Company’s voting securities outstanding immediately before such transaction hold securities that represent immediately after such merger or consolidation at least 20% of the combined voting power of the then outstanding voting securities of either the Company or the other surviving entity or its parent, or (c) the stockholders of the Company approve (i) a plan of complete liquidation or dissolution of the Company or (ii) an agreement for the Company's sale or disposition of all or substantially all the Company's assets, and such liquidation, dissolution, sale, or disposition is consummated. Further, upon a substantial corporate change, if awards are not assumed, substituted or continued, the awards shall immediately vest and become exercisable before the consummation of the transaction. For purpose of the stock incentive plans, a “substantial corporate change” means: (w) dissolution or liquidation of the Company, (x) merger, consolidation, or reorganization of the Company with one or more corporations in which the Company is not the surviving corporation, (y) the sale of substantially all of the assets of the Company to another corporation, or (z) with respect to the 1998 Plan, any transaction (including a merger or reorganization in which the Company survives) approved by the Board that results in any person or entity (other than any affiliate of the Company as defined in Rule 144(a)(1) under the Securities Act) owning 100% of the combined voting power of all classes of stock of the Company, and, with respect to the 2007 Plan, a person acquires ownership of 100% of the combined voting power of all classes of stock of the Company.

The table below summarizes the potential termination and change of control payments described above for each of the named executive officers, excluding any payments that may be available under the Company’s company-wide severance plan, which provides payments that do not discriminate in scope, terms or operation, in favor of executive officers of the Company and that are available generally to all salaried employees, including the named executive officers. The terms defined above apply to those used in this table. Unless otherwise specifically noted below, all amounts assume that the triggering event in question — the termination upon a change of control, termination without cause or for good reason, death or disability — occurred on December 31, 2013, the last business day of 2013.

____________


(1)	Consists of the values realizable by the named executive officers with respect to unvested stock options (that are in-the-money) and restricted stock under the Company’s 1998 and 2007 Plans in the event of a change of control or substantial corporate change, as defined in the plans and described above, as of December 31, 2013, which values are summarized in the table below.

The intrinsic value of the stock options was calculated by multiplying the number of shares underlying the unvested options by the difference between the exercise price of each unvested option and the closing price of the Company’s common stock ($184.58) on December 31, 2013, excluding options with an exercise price greater than the closing price on December 31, 2013. The intrinsic value of the restricted stock was calculated using the closing price of the Company’s common stock on December 31, 2013 ($184.58).



Name	Unvested (in-the-money) Options (# shares)	Intrinsic Value		Unvested Restricted Stock (# shares)	Intrinsic Value		Total
Andrew C. Florance	98,034	$	9,908,230	201,634	$	37,217,604	$	47,125,834
Brian J. Radecki	27,434	$	2,871,552	50,767	$	9,370,573	$	12,242,125

Jennifer L. Kitchen	10,934	$	1,156,788	19,368	$	3,574,945	$	4,731,734

(2)

Includes base salary for one year ($563,750), bonus for 2013 ($1,127,500), and the immediate vesting of all unvested stock options ($9,908,230). The value of stock option vesting included in this amount was calculated by multiplying the number of unvested options by the difference between the exercise price of each unvested option and the closing price of the Company’s common stock ($184.58) on December 31, 2013, excluding options with an exercise price greater than the closing price on December 31, 2013.


(3)	Consists of the cash incentive bonus for 2013.

(4)

Mr. Florance’s employment agreement provides for a termination payment if there is an acquisition or change of control of the Company and Mr. Florance terminates his employment within one year after that event. Assuming, for these purposes, that those conditions are met as of December 31, 2013, Mr. Florance would be entitled to the amount set forth, which includes base salary for one year ($563,750), his cash incentive bonus for 2013 ($1,127,500), the immediate vesting of all unvested stock options ($9,908,230) and all unvested restricted stock ($37,217,604) under the respective stock incentive plans, and an estimated gross-up payment to cover taxes assessed under Section 4999 of the Tax Code ($25,149,121). The value of stock option vesting included in this amount was calculated by multiplying the number of unvested options by the difference between the exercise price of each unvested option and the closing price of the Company’s common stock ($184.58) on December 31, 2013, excluding options with an exercise price greater than the closing price on December 31, 2013. The value of the restricted stock was calculated by multiplying the number of outstanding restricted shares by the closing price of the Company’s common stock on December 31, 2013 ($184.58).

Company-Wide Severance Policy

As described above under “Termination and Change of Control Payments,” in 2008, the Company adopted a company-wide severance plan that provides payments that do not discriminate in scope, terms or operation in favor of executive officers of the Company and that are available generally to all salaried employees, including the named executive officers. Pursuant to the company-wide severance policy, full-time staff who are part of a position reduction may receive severance pay equal to two weeks current base pay for the first year or less of employment, plus one week current base pay for each completed additional year of continuous service (up to a 16-week maximum payout) in exchange for a full release of claims. In the event of termination of employment as a result of a position reduction, under the Company-wide severance policy as of December 31, 2013, Mr. Radecki would be entitled to $110,385, Mr. Carchedi would be entitled to $28,846, Mr. Stanfill would be entitled to $102,500 and Ms. Kitchen would be entitled to $69,385. Mr. Florance would be entitled to the payments set forth in his employment agreement, which are described above.

Ms. Kitchen’s Separation and Release Agreement

On October 6, 2013, the Company entered into a separation and release agreement with Ms. Kitchen. Pursuant to that agreement, Ms. Kitchen agreed that her last day of employment with the Company will be the earlier of the date she begins employment with another employer or August 31, 2014 (the “Termination Date”). Ms. Kitchen remains an employee of the Company, continues to receive her base salary, and is eligible to participate in the Company’s health and benefit plans until the Termination Date. As such, Ms. Kitchen’s restricted stock and option grants will continue to vest through that date. Ms. Kitchen is not entitled to any additional options or stock grants nor is she eligible for any bonus or cash incentive payments after the date of the agreement. The Company will provide payments on Ms.

Kitchen’s behalf for family health care coverage under the consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) if Ms. Kitchen elects such coverage under the Company’s group health plan for up to four months post-Termination Date.

Pursuant to the separation and release agreement, Ms. Kitchen is subject to confidentiality and non-solicitation restrictive covenants and she has agreed to a general release of claims. The non-solicitation restrictions apply through the second anniversary of the Termination Date.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

None of our executive officers or directors engaged in or had a direct or indirect interest in any transactions with us during fiscal year 2013 that are required by SEC rules to be disclosed in this Proxy Statement.

The Board recognizes that Interested Transactions (as defined below) can present potential or actual conflicts of interest and create the appearance that Company decisions are based on considerations other than the best interests of the Company and its stockholders. In April 2006, the Board delegated authority to the Audit Committee to review and approve Interested Transactions, and the Audit Committee has adopted written procedures as detailed below for the review, approval, or ratification of Interested Transactions.

Pursuant to the Audit Committee’s procedures, an “Interested Transaction” is any transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness), or any series of similar transactions, arrangements or relationships, in which (a) the aggregate amount involved will or may be expected to exceed $100,000 in any calendar year, (b) the Company is a participant, and (c) any Related Party (as defined below) has or will have a direct or indirect interest (other than solely as a result of being a director or trustee (or any similar position) or a less than 10 percent beneficial owner of another entity). A “Related Party” is any (a) person who is or was (since the beginning of the last year for which the Company has filed an annual report on Form 10-K and proxy statement, even if they do not presently serve in that role) an executive officer, director or nominee for election as a director of the Company, (b) greater than 5% beneficial owner of the Company’s outstanding common stock, or (c) Immediate Family Member of any of the foregoing. An “Immediate Family Member” is any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law and any person (other than a tenant or employee) sharing the household of a person.

The Audit Committee will review all of the relevant facts and circumstances of all Interested Transactions and either approve or disapprove of the entry into the Interested Transaction, subject to a limited list of enumerated transactions which are deemed to be pre-approved as described in the Interested Transactions policy. In determining whether to approve an Interested Transaction, the Audit Committee will take into account, among other factors it deems appropriate, whether the Interested Transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the Related Party’s interest in the transaction.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires that our directors and executive officers, and anyone who beneficially owns more than 10% of our common stock, file with the SEC reports of initial ownership and reports of changes in ownership of our common stock, and to furnish us with copies of those reports. Based solely on a review of the reports furnished to us and on written representations from reporting persons, we believe that during 2013, our directors, executive officers and 10% stockholders filed the required reports under Section 16(a) on a timely basis.

OTHER INFORMATION

We have made available a copy of our Annual Report for the year ended December 31, 2013 and our annual report on Form 10-K for the year ended December 31, 2013 with this Proxy Statement. In addition, you may obtain a copy of our annual report on Form 10-K, including the financial statements and financial statement schedules, without charge by sending a written request to Rich Simonelli, Director of Investor Relations, CoStar Group, Inc., 1331 L Street N.W., Washington, DC 20005.

If you and others who share your mailing address own common stock in street name, meaning through bank or brokerage accounts, you may have received a notice that your household will receive only one set of proxy materials from each company whose stock is held in such accounts. This practice, known as “householding,” is designed to reduce the volume of duplicate information and reduce printing and postage costs. Unless you responded that you did not want to participate in householding, you were deemed to have consented to it and a single copy of the Notice of Availability of Proxy Materials has been sent to your address. Each stockholder will continue to receive a separate voting instruction form. If you would like to revoke your consent to householding and in the future receive your own Notice of Availability of Proxy Materials or your own set of proxy materials, as applicable, or if your household is currently receiving multiple copies of the same items and you would like in the future to receive only a single copy at your address, please contact Broadridge Financial Services, Inc. either by calling 1-800-542-1061 or by writing to Broadridge Householding Department, 51 Mercedes Way, Edgewood NY 11717. A revocation of consent to householding will be effective 30 days following its receipt. We will deliver promptly, upon written or oral request, a separate copy of the proxy materials for the Annual Meeting to a stockholder at a shared address to which a single copy of the materials was delivered. This request should be made by sending a written request to Rich Simonelli, Senior Director of Investor Relations, CoStar Group, Inc., 1331 L Street N.W., Washington, DC 20005 or by calling Mr. Simonelli at (202) 346-6500.

This Proxy is solicited on behalf of the Board of Directors. The Company will bear all expenses in connection with the Annual Meeting and this proxy solicitation. We have also retained Innisfree M&A Incorporated to assist in distribution of these proxy materials and soliciting proxy voting instructions, at an estimated cost not to exceed $10,000, plus reasonable expenses. Proxies may be solicited by certain of our directors, officers and employees, without additional compensation, in person, by telephone, by mail, telegram, facsimile, or other electronic or other means. Innisfree M&A Incorporated will request that brokerage houses, banks and other custodians forward proxy material to beneficial owners of our common stock. We will reimburse brokerage houses, banks, and other custodians for their reasonable expenses for forwarding these materials to beneficial owners. Broadridge Financial Services, Inc. will act as proxy tabulator.
