DIAMOND HILL INVESTMENT GROUP, INC. 2012 ANNUAL REPORT NOTICE OF 2013 ANNUAL MEETING AND PROXY STATEMENT DIAMOND HILL INVESTMENT GROUP, INC. ANNUAL LETTER TO SHAREHOLDERS March 14, 2013 Dear Fellow Shareholders: From the beginning, we have placed our fiduciary responsibility to our clients at the top of our corporate objectives. The fulfillment of this responsibility is necessary (but not sufficient) for our continued business suc- cess. Through separate accounts, mutual funds, and limited partnerships, all of our strategies have provided our clients with competitive investment returns since their respective inceptions. For the five-year period beginning in 2008 (the year of the financial crisis) through the end of 2012, our clients’ investment results were closer to average, yet improving in the last six months of 2012. My belief is that over the next five years, we will achieve better than average results for our clients, continuing to fulfill our primary corporate objective as a fiduciary to our clients with competitive long-term investment results. Financial Results Revenue was $67 million in 2012 compared with $64 million in 2011 and $41 million in 2007. Assets under management (AUM) finished the year at $9.4 billion, up from $8.7 billion in 2011 and $4.4 billion in 2007. Our operating profit margin of 36.7% was slightly ahead of 2011. We believe that our growth and profitability last year was above average for our industry and much better than average for companies similar in size. These financial results are consistent with meeting our secondary corporate goal to grow the intrinsic value per share value of Diamond Hill. With our existing strategy offerings, we estimate AUM capacity in the range of $20 to $30 billion. Five years ago, Diamond Hill paid its first cash dividend, and we have paid a cash dividend each year since. In total, we have paid $46 per share in cash dividends, about 60% of which represented a return of capital. It is important to note that during the past five years, our tangible book value per share has declined due to these divi- dends, from $17.52 at the end of 2007 to $6.86 at the end of 2012. The dividends of $46 per share and the $10.66 decline in tangible book value per share results in a net number of $35.34 per share, which represents one meas- ure of change in shareholder value during the past five years (an annualized rate of 15% percent for the five years). While tangible book value is a component of intrinsic value, the percentage of intrinsic value represented varies considerably between companies. The above discussion is comparable with another popular measure: total shareholder return (TSR), which takes into account both cash returned to shareholders and change in stock price. For us, this results in a calcu- lation of about 12% annualized over the past five years. TSR is similar to the evaluation of professional investors like us. The efficacy of our portfolio management is evaluated based on a total return which includes both divi- dends paid on our holdings and stock price changes. We purchase stocks for client portfolios that are at a dis- count to our estimate of intrinsic value, and we sell stocks when they reach our estimate of intrinsic value. Since our firm’s inception, we have done this well resulting in above average results for our clients, growth in our business, and growth in Diamond Hill’s intrinsic value per share. Much of that value has been distributed to shareholders as mentioned above. While the current stock price represents the market’s estimate of a company’s intrinsic value, a premise of our investment philosophy is that price and intrinsic value often differ, sometimes substantially. Thus, we believe the relevant measure of value creation (in addition to cash returned to share- holders) is the change in Diamond Hill’s intrinsic value. Firm Sustainability During our first five years, Diamond Hill became financially viable, and during the next five years, the firm became consistently profitable. In my 2009 shareholder letter, dated April 5, 2010, I stated that we would spend the next five years continuing to build our infrastructure and capacity to make the firm sustainable. Creating sus- tainability helps us in fulfilling our fiduciary duty to clients while also providing a key component for growth in the firm’s intrinsic value. Given the competitive nature of our industry, to achieve sustainability we must attract and retain talented investment personnel. We have continued to grow our internal research capabilities with the addition of three new research associates in 2012. Our research team now consists of 15 research analysts and 6 research associates, and importantly, we have had no turnover in our equity portfolio manager or our research analyst ranks. Our research is primarily focused on U.S. companies; however, we have been expanding our focus to include international companies with the objective of being better investors through a deeper understanding of non-U.S. based companies in this time of increasing globalization. It is possible that these additional international research capabilities may lead us to establish global and international strategies in the future; however, there are no active plans for a new global or international strategy at this time. We must also attract and retain people who contribute to the other important aspects of our business. In recent years, we have expanded our sales, marketing, and client services staff as our opportunities and revenue increased in response to our investment results. Most significantly, Lisa Wesolek joined us in 2012 as Managing Director and Head of Distribution. Prior to joining Diamond Hill, Lisa held senior roles at various institutions including JPMorgan Asset Management and Wells Fargo Funds Management Group. Succession Planning The process of succession planning is among the most important efforts underway at Diamond Hill. My own plan is to continue to serve as CEO through the end of 2015 and as an investment team member and portfolio manager for our Long-Short strategy beyond 2015. Because of this plan, it is increasingly important that my duties be shared among the many talented individuals at Diamond Hill in order to achieve organizational sustain- ability. In December 2012, we named a Senior Management Team with Co-Chief Investment Officer Chris Bingaman, Co-Director of Research Rick Snowdon, and Head of Distribution Lisa Wesolek joining Chief Finan- cial Officer Jim Laird and me. We now have deep experience in all functions of our business, which will help us continue the success of our first twelve years. Alignment of Interests Our success is dependent on a proven investment philosophy combined with high-performing people and alignment of our interests with those of our clients. Diamond Hill associates are aligned with clients as a result of their personal investments in U.S. equities through our Diamond Hill Funds, rather than funds of other invest- ment managers or individual equity securities. Collectively, Diamond Hill associates are one of the largest share- holders in our Funds. Also, every Diamond Hill associate is an owner in the firm through grants of Diamond Hill stock at the outset of their employment, 401(k) matching, and eligibility for incentive compensation paid in Diamond Hill shares, the latter of which is restricted from sale for five years reinforcing our long-term invest- ment temperament. In fact, we believe that taking a long-term view is perhaps our greatest competitive advan- tage. While the perception of near-term profit opportunities often attracts significant amounts of capital and erodes excess returns, there are far fewer investors willing to deploy capital based on an investment horizon of five years or more. At many institutions, the career risk associated with being wrong in the short term is simply too great for analysts to consider investment opportunities that may play out over years instead of quarters. At our annual meeting this April, we will honor our outgoing Audit Committee Chairman Dave Lauer. Dave was first elected to the board in 2002, and his vast knowledge and experience has been especially valuable in helping us to provide our shareholders with financial statements that are both transparent and thorough. I would like to thank my colleagues and our Board of Directors for their support. Over my remaining three years as CEO, I intend to strive for continuous improvement in all areas of our business, and as a portfolio manager (a role in which I intend to continue for many years after 2015) I intend to serve our clients with competitive investment returns. Sincerely, R. H. Dillon President and Chief Executive Officer Diamond Hill Investment Group, Inc. 325 John H. McConnell Boulevard, Suite 200 Columbus, Ohio 43215 March 14, 2013 Dear Shareholders: We cordially invite you to attend the 2013 Annual Meeting of Shareholders of Diamond Hill Investment Group, Inc. to be held at 325 John H.

A: At the Annual Meeting, you will be asked to consider and vote upon: (i) the election of seven directors to serve on the Board until the Company’s 2014 Annual Meeting of Shareholders and until their successors have been duly elected and qualified; (ii) a proposal to ratify the appointment of KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2013; and (iii) a non-binding, advisory resolution to approve the compensation of the Company’s named executive officers. Q: What do I need to do now? A: After carefully reading this Proxy Statement, indicate on the enclosed proxy card how you want your shares to be voted and sign and mail the proxy card promptly in the enclosed envelope. Alternatively, you may vote by phone by using the control number identified on your proxy card, or vote over the Internet in accordance with the instructions on your proxy card. The deadline for transmitting voting instructions over the Internet or telephonically is 11:59 p.m. Eastern Daylight Saving Time on Tuesday, April 23, 2013. If you vote by phone or over the Internet you do not need to return a proxy card. You should be aware that if you vote over the Internet or by phone, you may incur costs associated with electronic access, such as usage charges from Internet service providers and telephone companies. Q: What does it mean if I get more than one proxy card? A: If your shares are registered in more than one account, you will receive more than one proxy card. If you intend to vote by mail, sign, date and return all proxy cards to ensure that all your shares are voted. If you are a record holder and intend to vote by telephone or over the Internet, you must do so for each individual proxy card you receive. Q: What is the difference between holding shares as a shareholder of record and as a beneficial owner? A: Many shareholders are beneficial owners, meaning they hold their shares in “street name” through a broker, bank or other nominee. As summarized below, there are some distinctions between shares held of record and those owned beneficially. Shareholder of Record. For shares registered directly in your name with the Company’s transfer agent, you are considered the shareholder of record and we are sending this Proxy Statement and related materials directly to you. As a shareholder of record, you have the right to vote in person at the Annual Meeting or you may grant your proxy directly to the Board’s designees by completing, signing and returning the enclosed proxy card, or transmitting your voting instructions over the Internet or by phone. Beneficial Owner. For shares held in “street name”, you are considered the beneficial owner and this Proxy Statement and related materials are being forwarded to you by your broker, bank or other nominee, who is the shareholder of record. As the beneficial owner, you have the right to direct your broker or other nominee on how to vote your shares. Your broker or nominee will provide you with information on the procedures you must follow to instruct them how to vote your shares or how to revoke previously given voting instructions. Q: If my shares are held in “street name” by my broker, will my broker vote my shares for me? A: Your broker will vote your shares in the manner you instruct and you should follow the voting instructions provided to you by your broker. However, if you do not provide voting instructions to your broker, it may 1 vote your shares in its discretion on certain “routine” matters. The ratification of the appointment of KPMG as our independent registered public accounting firm for the 2013 fiscal year is considered routine, and if you do not submit voting instructions, your broker may choose, in its discretion, to vote or not vote your shares on the ratification. None of the other matters to be voted on at the Annual Meeting are routine, and your broker may not vote your shares on those matters without your instructions. Q: May I revoke my proxy or change my vote after I have mailed a proxy card or voted electronically over the Internet or by telephone? A: Yes. You can change your vote at any time before your proxy is voted at the Annual Meeting. If you are the record holder of the shares, you can do this in three ways: • send a written statement to James F. Laird, our Secretary, stating that you would like to revoke your proxy, which must be received prior to the Annual Meeting; • send a newly signed and later-dated proxy card, which must be received prior to the Annual Meeting, or submit later-dated electronic voting instructions over the Internet or by telephone no later than 11:59 p.m. Eastern Daylight Saving Time on April 23, 2013; or • attend the Annual Meeting and revoke your proxy in person prior to the start of voting at the Annual Meeting or vote in person at the Annual Meeting (attending the Annual Meeting will not, by itself, revoke your proxy or a prior Internet or telephone vote). If you are a beneficial owner, you may change your vote by submitting new voting instructions to your broker or nominee, and you should review the instructions provided by your broker or nominee to determine the procedures you must follow. Q: Can I vote my shares in person at the Annual Meeting? A: You may vote shares held of record in person at the Annual Meeting. If you choose to attend, please bring the enclosed proxy card and a form of identification. If you are a beneficial owner and you wish to attend the Annual Meeting and vote in person, you will need a signed proxy from your broker or other nominee giving you the right to vote your shares at the Annual Meeting and a form of identification. To obtain directions to attend the Annual Meeting and vote in person, please call James F. Laird, the Company’s Secretary, at (614) 255-3353 or visit the Company’s website, http://www.diamond-hill.com/cgi-bin/cu/office-location.pl. Q: How will my shares be voted if I submit a proxy without voting instructions? A: If you submit a proxy and do not indicate how you want your shares voted, your proxy will be voted on the matters presented as recommended by the Board. The Board’s recommendations are set forth in this Proxy Statement. Q: Who can answer my questions about how I can submit or revoke my proxy or vote by phone or via the Internet? A: If you are a record shareholder and have more questions about how to submit your proxy, please call James F. Laird, the Company’s Secretary, at (614) 255-3353. If you are a beneficial owner, you should contact your broker or other nominee to determine the procedures you must follow. THE ANNUAL MEETING The Annual Meeting will be held at 325 John H. McConnell Blvd., Columbus, Ohio 43215, on Wednesday, April 24, 2013, at 2:00 p.m. Eastern Daylight Saving Time. The purposes of the Annual Meeting are to consider and vote upon (i) the election of seven directors to serve on the Board until the Company’s 2014 Annual Meeting of Shareholders and until their successors have been duly elected and qualified; (ii) a proposal to ratify the appointment of KPMG as the Company’s independent registered public accounting firm for the fiscal year end- ing December 31, 2013; and (iii) a non-binding, advisory resolution to approve the compensation of the Compa- ny’s named executive officers. We are not currently aware of any other matters that will come before the Annual Meeting. 2 PROCEDURAL MATTERS Record Date Only our shareholders of record at the close of business on March 1, 2013, the record date, will be entitled to vote at the Annual Meeting. As of the record date, there were 3,231,318 of common shares outstanding and entitled to vote at the Annual Meeting. Proxy Your shares will be voted at the Annual Meeting as you direct on your signed proxy card or in your tele- phonic or Internet voting instructions. If you submit a proxy card without voting instructions, it will be voted as recommended by the Board. These recommendations are set forth in this Proxy Statement. The duly appointed proxy holders will vote in their discretion on any other matters that may properly come before the Annual Meet- ing. Voting Each outstanding share may cast one vote on each separate matter of business properly brought before the Annual Meeting. If you hold shares in street name, the Board encourages you to instruct your broker or other nominee as to how to vote your shares. A shareholder voting in the election of directors may cumulate such shareholder’s votes and give one candi- date a number of votes equal to (i) the number of directors to be elected (seven), multiplied by (ii) the number of shares held by the shareholder, or may distribute such shareholder’s total votes among as many candidates as the shareholder may select. However, no shareholder will be entitled to cumulate votes unless the candidate’s name has been placed in nomination prior to voting and a shareholder has given us notice at least 48 hours prior to the Annual Meeting of the intention to cumulate votes. The proxies the Board is soliciting include the discretionary authority to cumulate votes. If cumulative voting occurs at the Annual Meeting, the proxies intend to vote the shares represented by proxy in a manner to elect as many of the seven director nominees as possible. Cumulative voting only applies to the election of directors. Director elections. The affirmative vote of the holders of a plurality of the shares represented at the Annual Meeting, in person or by proxy, and entitled to vote is required for the election of directors, and the seven nominees receiving the most votes will be elected. Ratification of selection of independent registered public accounting firm. The affirmative vote of a majority of the shares represented at the Annual Meeting, in person or by proxy, and entitled to vote on the pro- posal is required to ratify the selection of KPMG as the Company’s independent registered public accounting firm for fiscal year 2013. Advisory approval of named executive officer compensation. The affirmative vote of a majority of the shares represented at the Annual Meeting, in person or by proxy, and entitled to vote on the proposal is required for shareholder advisory approval of the compensation of the Company’s named executive officers. Effect of broker non-votes and abstentions. Under the applicable regulations of the Securities and Exchange Commission (the “SEC”) and the rules of exchanges and other self-regulatory organizations of which the brokers are members, brokers who hold common shares in street name may sign and submit proxies and may vote our common shares on certain “routine” matters. The ratification of KPMG is considered routine. Brokers may not vote street name shares on the election of directors or approval of the compensation of our named execu- tive officers without specific instructions from the customer who owns the shares. Proxies that are signed and submitted by brokers that have not been voted on certain matters are referred to as “broker non-votes.” Neither broker non-votes nor abstentions will have any effect on the election of directors. Abstentions will have the same effect as a vote against the ratification of the appointment of KPMG and the advisory approval of named executive officer compensation; although, broker non-votes will have no effect on those proposals. 3 Quorum Business can be conducted at the Annual Meeting only if a quorum, consisting of at least the holders of a majority of our outstanding shares entitled to vote, is present, either in person or by proxy. Abstentions and broker non-votes will be counted toward establishing a quorum. If a quorum is not present at the time the Annual Meeting is convened, a majority of the shares represented in person or by proxy may adjourn the Annual Meeting to a later date and time, without notice other than announcement at the Annual Meeting. At any such adjourn- ment of the Annual Meeting at which a quorum is present, any business may be transacted which might have been transacted at the Annual Meeting as originally called. Solicitation; Expenses The Company will pay all expenses of the Board’s solicitation of the proxies for the Annual Meeting, includ- ing the cost of preparing, assembling and mailing the Notice, form of proxy and Proxy Statement, postage for return envelopes, the handling and expenses for tabulation of proxies received, and charges of brokerage houses and other institutions, nominees or fiduciaries for forwarding such documents to beneficial owners. The Com- pany will not pay any electronic access charges associated with Internet or telephonic voting incurred by a share- holder. The Company may solicit proxies in person or by telephone, facsimile or e-mail.

Compensation of Directors The Compensation Committee is responsible for periodically reviewing and recommending to the Board the compensation of non-employee directors. At the discretion of the Board, directors are eligible to receive stock- based awards under the Diamond Hill Investment Group, Inc. 2011 Equity and Cash Incentive Plan (the “2011 Plan”). After a thorough review of the compensation of non-employee directors, the Compensation Committee 10 recommended a change in our non-employee director compensation structure from an annual payment structure to the use of long-term cliff vesting restricted stock awards, as a way to further align the interests of the directors with the long-term interests of shareholders. The Board adopted the Compensation Committee’s recommendation and effective, January 1, 2012, independent directors will be compensated using cliff vesting restricted stock grants, which are intended to compensate the directors for a period of time, which is the shorter of five years or a director’s expected retire- ment date. The restricted stock grants are intended to fully compensate directors for their services as directors and as members of committees of the Board. After the restricted stock grants vest, our Corporate Governance Guidelines prohibit the shares from being sold while the director remains on the Board. The following table summarizes the changes: Previous Compensation Structure 2011 2012 New Compensation Structure* 2014 2013 2015 2016 Total Compensation — Company Stock . . . . . . . . . . . . . . . .

The 6,000 shares represented in the above table is compensation for a full five year period. Directors expected to retirement earlier than five years were awarded share amounts less than 6,000 to reflect the expected reduced period over which they will serve as a Director. In 2012, the non-employee directors each received a cliff vesting restricted stock grant. Non-employee direc- tors, who are eligible to serve on the board for five years or longer, received a cliff vesting restricted stock grant of 6,000 shares intended to fully compensate them for their services through 2016. These directors will not be eligible to receive another cliff vesting restricted stock grant until 2017. Non-employee directors, who are expected to retire within 5 years, received a cliff vesting restricted stock grant intended to fully compensate them for their services until they retire from the Board. The following table sets forth information regarding the compensation earned by, or paid to, directors who served on our Board in 2012. Mr. Dillon and Mr. Laird, who are executive officers of the Company, do not receive separate directors’ fees for their service and have been omitted from this table. As discussed above, direc- tors earned and received no cash compensation in 2012 and instead received a cliff vesting restricted stock grant that is intended to fully compensate them for a period of time, which is the shorter of five years or a director’s expected retirement date.

His compensation represents service in 2012 prior to the 2012 Annual Meeting. (4) Pursuant to the Company’s Corporate Governance Guidelines, Mr. Lauer and Mr. Shackelford are scheduled to retire from the Board in conjunction with the Annual Shareholder meeting in 2013 and 2015, respectively. Their compensation is intended to represent service from January 1, 2012 until their respective retirements. (5) Mr. Shoup was appointed to the Board on April 25, 2012. His compensation represents service after his appointment to the Board and is intended to represent service for the five year period ending April 30, 2017. Ownership and Retention Guidelines Our Corporate Governance Guidelines prohibit shares granted to our directors as compensation from being sold while the director remains on the Board. Therefore, we expect each non-employee director to hold for his or her entire term of service on the Board all of the shares of our common stock granted to the director as compensation. Non-employee directors may not sell any of the shares granted to them until they conclude their service as a director. CORPORATE GOVERNANCE The Nominating and Governance Committee has general oversight responsibility for assessment and recruit- ment of new director candidates, as well as evaluation of director and board performance and oversight of gover- nance matters for the Company. The Committee originally adopted Corporate Governance Guidelines on February 25, 2010 and reviews them annually. The most current version of the Guidelines is available on our website, www.diamond-hill.com, by clicking the “Investor & Media Relations” tab, then the “Investor Relations” section, and finally the “Corporate Governance” tab. Board Leadership and Composition We believe separating the roles of Chairman and CEO provides for a strong governance and oversight struc- ture. Mr. Shackelford has served as independent non-executive chairman since 2011 and Mr. Dillon has served as CEO since joining the Company in 2000. These roles have been separate since 2000. The Chairman approves Board agendas and schedules, chairs all executive sessions of the independent directors, acts as the liaison between the independent directors and management, oversees the information distributed in advance of Board meetings, is available to the Secretary to discuss and, as necessary, respond to shareholder communications to the Board, and calls meetings of the independent directors. 12 Currently, five of the seven directors are independent under NASDAQ standards. If the proposed directors are elected, five of our seven directors will still be independent. In addition, the Nominating and Governance Committee, the Audit Committee, and the Compensation Committee are all comprised entirely of independent directors. Overall, the Company believes that its Board structure is designed to foster critical oversight, good governance practices, and the interests of the Company and its shareholders. Among other things, the Corporate Governance Guidelines address term limits of each director. Although we have a 10 year service limit for directors, the Guidelines authorize the Board to make exceptions to this limi- tation and permit directors to serve for an additional year. Board’s Role in Risk Oversight The Board’s role in the Company’s risk oversight process includes receiving regular reports from members of senior management on areas of material risk to the Company, including client investment results, operational, financial, legal, regulatory, and strategic risks. The Audit Committee is responsible for overseeing risks relating to the Company’s accounting matters, financial reporting and legal and regulatory compliance. To satisfy these oversight the Audit Committee meets regularly with management and the Company’s independent registered public accounting firm. The Compensation Committee is responsible for overseeing risks relating to employment policies and the Company’s compensation and benefits programs. To satisfy these over- sight responsibilities, to understand the implications of compensation decisions, particularly the risks that the Company’s compensation policies pose to its finances and its relationship with employees. the Compensation Committee meets regularly with management responsibilities, Planning Group and Senior Management Team During 2009, the Company formed the Planning Group, which is comprised of seven associates representing all functional areas of the organization. The Planning Group was formed to address important Company issues and provide counsel to the CEO and CFO. The Planning Group collaborates and recommends action on various company initiatives and the overall direction of the firm, although ultimate decision making authority remains with our CEO and CFO. The Planning Group is comprised of the following individuals: Christopher Bingaman — portfolio management, Christopher Welch — portfolio management, William Zox — portfolio management, Richard Snowdon — investment research, Laurie Riebel — client management, Lisa Wesolek — business development, and Gary Young — business management. The Planning Group also plays a role in the Company’s overall succession planning efforts. In December 2012, the Company created a Senior Management Team, which includes the CEO, CFO, Mr. Bingaman, Mr. Snowdon, and Ms. Wesolek. Each member of the Senior Management Team will report directly to the CEO and be responsible for the following functional areas of the company: Mr. Laird — Finance, Administration, and Compliance; Mr. Bingaman — Portfolio Management; Mr. Snowdon — Research; and, Ms. Wesolek — Client Service, Marketing, and Business Development. In conjunction with the creation of the Senior Management Team, the Planning Group has been temporarily dissolved. In the future, the Company plans to reconstitute the Planning Group to continue to provide input to the Senior Management Team, provide a source of leadership development, and play a role in the Company’s overall succession planning efforts. When reconstituted, the Planning Group may or may not consist of the same mem- bers who were serving when it was dissolved. The Company believes that the Senior Management Team in con- junction with a reconstituted Planning Group is an appropriate and effective organizational structure for Diamond Hill. Director Orientation and Continuing Education and Development When a new independent director joins the Board, the Company provides a formal orientation program for the purpose of providing the new director with an understanding of the operations and the financial condition of the Company. In addition, each director is expected to maintain the necessary level of expertise to perform his or her responsibilities as a director. To assist the directors in maintaining such level of expertise, we may, from time to time, offer continuing education programs in addition to briefings during Board meetings relating to the com- petitive and industry environment and the Company’s goals and strategies. 13 Director Qualifications and the Nominations Process The Nominating and Governance Committee believes that the nominees presented in this proxy statement would constitute a Board with an appropriate level and diversity of experience, education, skills, and independence. The Nominating and Governance Committee routinely considers the current composition of the Board, and whether changes should be made or additional directors should be added to the Board. The Nominating and Governance Committee supervises the nomination process for directors. It considers the performance, independence, diversity, and other characteristics of our incumbent directors, including their willingness to serve, and any change in their employment or other circumstances in considering their nomination each year. The Nominating and Governance Committee also considers diversity of background and experience as well as gender and other forms of diversity. We do not, however, have any formal policy regarding diversity in identifying nominees for a directorship, but rather we consider it among the various factors relevant to any particular nominee and the overall needs of the Board. In the event that a vacancy exists or the Company decides to increase the size of the Board, the Nominating and Corporate Governance Committee will identify, interview, examine, and make recommendations to the Board regarding appropriate candidates. The Nominating and Governance Committee identifies potential candidates principally through suggestions from the Company’s directors and senior management. The committee may also seek candidates through informal discussions with third parties. We have not historically retained search firms to help identify director candidates and did not do so in identifying this year’s nominees. In evaluating potential candidates, the Nominating and Governance Committee considers, among other fac- tors, independence from management, experience, expertise, commitment, diversity, number of other public company board and related committee seats held, potential conflicts of interest, and the composition of the Board at the time of the assessment. All candidates for nomination must: • demonstrate strong character and integrity; • have sufficient time to carry out their duties; • have experience at senior levels in areas of expertise helpful to the Company and consistent with the objective of having a diverse and well-rounded Board; and • have the willingness and commitment to assume the responsibilities required of a director of the Company. In addition, candidates expected to serve on the Audit Committee must meet independence and financial literacy qualifications required by NASDAQ, the SEC, and other applicable laws and regulations. Candidates expected to serve on the Nominating and Governance Committee and on the Compensation Committee must meet independence qualifications set out by NASDAQ. The evaluation process of potential candidates also includes personal interviews, and discussions with appropriate references. Once the Nominating and Governance Committee has selected a candidate, it recommends the candidate to the full Board for election if a vacancy occurs or is created by an increase in the size of the Board during the course of the year, or for nomination if the director is to be first elected by shareholders. All directors serve for one-year terms and must stand for reelection annually. The Nominating and Governance Committee does not currently have any specific policies regarding the consideration of director candidates recommended by shareholders due to a historical absence of shareholder recommendations. The Nominating and Governance Committee will consider shareholder recommendations for directors using the process and criteria set forth above. In the future, the Nominating and Governance Committee may in its discretion adopt policies regarding the consideration of director candidates recommended by share- holders. Shareholder recommendations for Board candidates must be directed in writing to the Company at 325 John H. McConnell Boulevard, Suite 200, Columbus, Ohio 43215, Attention: Secretary, and must include the candidate’s name, home and business contact information, detailed biographical data and qualifications, information regarding any relationships between the candidate and us within the last three years, and evidence of the recommending person’s ownership of our common shares. 14 Certain Relationships and Related Person Transactions The Board recognizes that related person transactions present a heightened risk of conflicts of interest. We currently have no related person transactions reportable pursuant to Item 404(a) of SEC Regulation S-K and have not had any such transactions in the recent past. As such, we do not believe it is necessary to have a written policy specifically dealing with related person transactions. The Audit Committee will review any potential related person transactions as they arise and are reported to the Board or the Audit Committee, regardless of whether the transactions are reportable pursuant to Item 404. No such transactions arose or were reviewed by the Audit Committee in 2012. For any related person transaction to be consummated or to continue, the Audit Committee must approve or ratify the transaction. Compensation Committee Interlocks The members of the Compensation Committee during 2012 were Ms. Skinner, Mr. Moran and Mr. Shackelford. No director who served on the Compensation Committee during 2012 currently is, or during 2012 was an officer, employee or former officer of the Company or had any relationship during 2012 requiring disclosure by us under Item 404 of SEC Regulation S-K. During 2012, none of our executive officers served as a member of the board of directors or compensation committee of any other company that has an executive officer serving as a member of our Board or Compensation Committee. EXECUTIVE OFFICERS AND COMPENSATION INFORMATION R. H. Dillon and James F. Laird are the Company’s only named executive officers. Their experience is described above under the heading “PROPOSAL 1 — ELECTION OF DIRECTORS.” The Company has no executive officers other than our named executive officers. Each named executive officer devotes his full time and effort to the affairs of the Company. Compensation Discussion and Analysis In our Compensation Discussion and Analysis, we: • describe our compensation program objectives and how compensation for our named executive officers is determined; and • explain the tables and disclosures that follow. This Compensation Discussion and Analysis presents compensation information for the following individuals: • R. H. Dillon, who served as our Chief Executive Officer in 2012; and • James F. Laird, who served as our Chief Financial Officer in 2012. Background We are in the investment management industry. Human capital is the most important resource of companies in our industry. Attracting and retaining employees can be more difficult in our industry than in others because of how heavily our industry depends on the contributions of talented individuals. We have been able to attract and retain high-quality employees due to: • our investment-centric culture, • employee ownership in our business, • our central Ohio location, and • the nationally-competitive compensation we offer to our employees. Compensation, which is a critical element in a business dependent on talented employees, has a particularly significant impact on profitability in industries like ours that are not capital intensive. This requires a balancing 15 of the economics between increasing our operating profit margin and rewarding the employees who generate our profits and produce investment results for our clients. The balancing effort is particularly challenging for us because we were essentially a start-up in May 2000, but yet had the unusual legacy of being a publicly owned company, in contrast to the industry norm of partnership-like structures for investment management firms of similar size. As of February 28, 2013, employees and directors owned approximately 31.8% of the Company. In contrast, many competitor firms are owned entirely by their employees. Despite our unique ownership structure given our industry, we believe that industry norms are helpful benchmarks for evaluating the balancing effort. At our 2012 Annual Meeting of Shareholders, we asked our shareholders to vote upon an advisory reso- lution to approve the compensation of our executive officers. The compensation of our named executive officers was approved by 77% of the votes cast on the matter. The Compensation Committee of the Board (the “Committee”) believes that the results of the advisory vote on executive compensation are supportive of our previous compensation practices and of its overall judgment related to the compensation practices of the Com- pany and considered that endorsement in establishing the compensation awarded to our executive officers for 2012. Compensation Program Objectives We seek to attract and retain people with integrity, intelligence and energy. All employees are paid a com- petitive base salary, provided with competitive benefits and participate in an annual cash and equity incentive compensation program. The amount of individual incentive awards is based on an assessment of individual per- formance, while the amount of the overall available incentive pool is based on (i) overall firm investment and operating results, (ii) market compensation data, and (iii) the profitability of the firm compared to other invest- ment management firms. In addition to annual incentive compensation, upon commencing employment with the Company, most employ- ees are awarded equity grants as an incentive to their continued employment. Generally, these awards cliff vest after five years of employment to promote employee retention and long-term employee ownership. The Company also seeks to increase employee ownership because it believes such ownership encourages employees to act and think like owners. While compensation amounts differ depending upon position, responsibilities, performance and competitive data, the Company seeks to reward all employees with similar compensation components based on these objectives. Rewards Based on Performance Our primary business objective is to meet our fiduciary duty to clients. Specifically, our focus is on long- term, five-year investment returns, with goals defined as rolling five-year periods in which client returns are sufficiently above relevant passive benchmarks, rank in the top quartile of similar investment strategies, and exceed a sufficient absolute return for the risk associated with the asset class. As it relates to our investment pro- fessionals, their compensation program is designed to reward performance that supports these objectives. For those employees who are not a part of our investment team, the compensation program varies but is based on rewarding individual performance that helps us meet our fiduciary duty to clients. Our second objective is to ful- fill our fiduciary duty to shareholders by managing the firm and its assets to increase shareholder value over time. Over the past five years, our annualized total shareholder return was 12.2% compared to a peer group aver- age of -4.2% and a 3.6% return for the Russell 2000 Index. Further, over the past five years, $46 per share has been returned to shareholders via special dividend distributions, much of which has been deemed a return of capital and therefore, is generally not currently taxable to our shareholders. Compensation Setting Process Role of the Compensation Committee The Committee has the overall responsibility for evaluating and approving the structure, operation and effec- tiveness of the Company’s compensation plans, policies and programs for all employees. The Committee consists 16 of Mr. Moran, Mr. Shackelford, and Ms. Skinner. Ms. Skinner serves as the Chair. Each member of the Commit- tee is an “outside director” for purposes of Section 162(m) of the Internal Revenue Code, a “non-employee direc- tor” for purposes of Section 16(b) of the Securities Exchange Act of 1934, and meets NASDAQ independence requirements. The Committee is specifically charged to: • review and approve the corporate goals and objectives relevant to the compensation of the CEO, to eval- uate the CEO’s performance in light of these goals and objectives, and, based on this evaluation, make recommendations to the Board for the independent directors to approve the CEO’s compensation level (including any long-term incentive or other compensation under any incentive-based or equity-based compensation plan); • review management’s recommendations and make recommendations to the Board with respect to director and other non-CEO executive officer compensation; provided, however, that the Committee has full decision-making authority with respect to compensation intended to be performance-based compensation within the meaning of Section 162(m) of the Internal Revenue Code; • retain compensation consultants as it deems necessary to assist in its evaluation of director, CEO or other senior executive compensation programs or arrangements. The Committee also has the authority to obtain advice and assistance from internal or external legal, accounting or other advisors; • review management’s recommendations and make recommendations to the Board with respect to incentive-based compensation and equity-based compensation plans and programs that are subject to Board approval, and that may be applicable to all or any portion of the employees of the Company and/or its subsidiaries; and • exercise all power and authority of the Board in the administration of equity-based incentive compensa- tion plans. The Committee considers the sum of all pay elements when reviewing annual compensation recom- mendations for the named executive officers. Although the framework for compensation decision-making is tied to the Company’s overall financial performance and the creation of long-term shareholder value, the Committee retains discretion to make recommendations to the Board for the independent directors to approve individual compensation based on other performance factors such as demonstrated management and leadership capabilities and the achievement of certain investment results for client accounts and other strategic operating results. Role of Management The Company’s CEO evaluates the CFO as part of our annual review process and makes recommendations to the Committee regarding all elements of executive compensation paid to him. Changes in executive compensation proposed by the CEO are based on the CFO’s performance, the compensation of individuals with comparable responsibilities in competing or similar organizations, and the profitability of the Company. At the Committee’s request, the CEO and CFO attend Committee meetings to provide general employee compensation and other information to the Committee, including information regarding the design, implementation and admin- istration of the Company’s compensation plans. The Committee also meets in executive sessions without the presence of any executive officer whose compensation the Committee is scheduled to discuss. Use of Compensation Consultants and Surveys in Determining Executive Compensation The Committee’s written charter gives it the authority to retain an independent outside executive compensa- tion consulting firm to assist in evaluating policies and practices regarding executive compensation and provide objective advice regarding the competitive landscape. However, historically the Committee has not engaged compensation consultants and did not do so in 2012. Each year the Committee obtains and summarizes an asset management industry pay analysis prepared by McLagan Partners, a compensation specialist focusing on the asset management industry. The companies in the McLagan Partners’ analysis include over 150 public and private asset management companies with which the Company competes. This analysis provides the Committee with a general overview of compensation trends in the asset management industry. The Committee does not define a specific peer group, but rather takes a broad view 17 of the analysis. The Committee does not set any compensation elements or levels based on targeting a certain percentile from the survey, but rather sets compensation that it believes to be both competitive and based on the executive’s value to the Company. The survey is just one of many factors that the Committee considers when determining executive compensation. Management and the Committee believe this broad view of the analysis is appropriate because the Company competes with both public and private asset management firms regardless of their size and scope of operations. Elements of Compensation Base Salary Base salaries for the named executive officers are intended to provide a fixed level of cash compensation that is appropriate given the executive’s role in the organization. Generally, base salaries are determined by (i) scope of responsibility and complexity of position, (ii) performance history, (iii) tenure of service, (iv) internal equity within the Company’s salary structure, and (v) relative salaries of persons holding similar positions at companies within the investment management industry. Base salaries are designed to compensate knowledge and experience. In December 2012, the Committee made the determination not to increase the base salaries of the named executive officers for fiscal year 2013. Consistent with the Company’s desire to have the majority of total compensation paid to named executive officers at risk in the form of incentive compensation, only 35 and 21 percent of the total compensation of our CEO and CFO, respectively, in fiscal 2012 (as shown in the Summary Compensation table) was paid in the form of base salaries. In furtherance of this desire, the 100,000 share performance-based restricted stock award made to the CEO in May 2011 has vesting provisions based on the future operating performance of the Company, as described in the “Restricted Stock Award to Mr. Dillon” sec- tion below. Annual Cash Bonuses In March 2011, the Company entered into an amendment and restatement of its employment agreement with R. H. Dillon, the Company’s President and CEO. The Company agreed to amend and restate Mr. Dillon’s employment agreement to reflect the mutual desire of the Company and Mr. Dillon that he remain CEO for the next five years. The amended and restated agreement entitles Mr. Dillon to, among other things, an annual cash bonus equal to at least 5% of the Company’s operating income, subject to an annual cap of $640,000. Mr. Dillon earned a $640,000 cash bonus for 2012 because 5% of the Company’s operating income for fiscal year 2012 exceeded $640,000. The Committee believes this formula to determine a cash bonus is appropriate because it ties the amount of the bonus to operating income, but also caps the award at an amount that Mr. Dillon and the Committee believes is appropriate given broad market compensation data and the additional value of the separate restricted stock award to Mr. Dillon in 2011 (which is described in the following section). The Committee awarded a discretionary cash bonus to Mr. Laird, the Company’s CFO, to reward him for his strong performance and overall contributions to the Company in fiscal year 2012 The Committee believes that structuring Mr. Laird’s annual cash bonus as a discretionary cash bonus provides the Committee with the flexibility to consider all aspects of Mr. Laird’s performance and contributions to the Company and properly compensate him for the relative value he provided to the Company in fiscal year 2012. In determining the amount of Mr. Laird’s cash bonus, the Committee considered the Company’s overall operating results, contributions by Mr. Laird that may not be reflected in the operating results, and broad market compensation data. Restricted Stock Award to Mr. Dillon In May 2011, the Company awarded 100,000 shares of performance-based restricted stock to Mr. Dillon pursuant to the Company’s 2011 Plan. All of the shares will vest on January 1, 2016 if the Company’s cumu- lative operating profit (defined as the Company’s total revenue during the period beginning on January 1, 2011 and ending on December 31, 2015, excluding any investment income and gains and the revenue of the Compa- ny’s subsidiaries Beacon Hill Fund Services, Inc. and BHIL Distributors, Inc. (collectively, “Beacon Hill”), less the Company’s total operating expenses during such period, excluding Beacon Hill expenses, any investment losses and all taxes) equals or exceeds $75,000,000. The results of Beacon Hill are excluded from the cumulative operating profit because it is a separate subsidiary of the Company and is not yet material to the overall financial 18 results of the Company. If the Company’s cumulative operating profit during such period is less than $75,000,000, a number of shares of restricted stock equal to 100,000 multiplied by a fraction, the numerator of which will be the Company’s actual cumulative operating profit during such performance period and the denominator of which will be $75,000,000, will vest on January 1, 2016. Any shares of restricted stock that remain unvested will be forfeited on such date. All shares of restricted stock that vest on January 1, 2016 will remain subject to restrictions on sale or transfer following the vesting date. The restrictions on sale or transfer will lapse with respect to 20% of the vested shares of restricted stock on each anniversary of the vesting date. If Mr. Dillon dies or is disabled prior to December 31, 2015, a number of shares of restricted stock equal to 100,000 multiplied by a fraction, the numerator of which will be the number of whole months of service elapsed between January 1, 2011 and the date of death or disability and the denominator of which will be 60, will vest and become immediately transferable without restriction. If Mr. Dillon’s employment is terminated prior to January 1, 2016 without Cause or for Good Reason (each as defined in Mr. Dillon’s amended and restated employment agreement), a number of shares of restricted stock equal to 100,000 multiplied by the lesser of (i) a fraction, the numerator of which will be the Company’s actual cumulative operating profit during the period beginning on January 1, 2011 and ending on the date of termination of employment and the denominator of which will be $75,000,000, and (ii) a fraction, the numerator of which will be the number of whole months of service elapsed between January 1, 2011 and the date of termination of employment and the denominator of which will be 60, will vest and become immediately transferable without restriction. In the event of a Change in Control (as defined in Mr. Dillon’s amended and restated employment agreement), all 100,000 shares of restricted stock will immediately vest and become transferable without restriction. This restricted stock award is intended to comprise all of Mr. Dillon’s equity-based compensation for the 2011 fiscal year through the 2015 fiscal year and no additional equity awards to Mr. Dillon during that period are contemplated. The Committee believes this compensation structure will strongly align the long-term interests of Mr. Dillon with those of the Company and its shareholders and better advances the objectives of our compensa- tion program than the annual compensation structure used in prior years. In December 2012, the Company amended Mr. Dillon’s award agreement made under the 2011 Plan to clar- ify restrictions on dividends paid on the 100,000 share performance-based restricted stock grant described above. The amendment caused dividends paid in 2012 on the 100,000 share performance-based restricted stock grant to be placed in escrow and to be subject to the same vesting requirements as the stock grant. If the vesting require- ments are fulfilled, the dividend payments held in escrow will be transferred to Mr. Dillon. Discretionary Stock Award to Mr. Laird The Committee awarded a discretionary stock award to Mr. Laird to reward him for his strong performance and overall contributions to the Company in fiscal year 2012. The Committee believes that paying a discretionary stock bonus to Mr. Laird provides the Committee with the flexibility to consider all aspects of Mr. Laird’s per- formance and contributions to the Company as well as properly compensate him for the value he provided to the Company in fiscal year 2012. In addition, this stock award, while immediately vested, is restricted from sale or transfer for five years, which the Committee believes strongly aligns the long-terms interests of Mr. Laird with those of the Company and its shareholders. In determining the amount of the stock award, the Committee considered the contributions Mr. Laird made to the Company in 2012, specifically his leadership in the day to day management of the Company, oversight of financial matters, compliance, and internal controls, all of which contribute to the Company’s overall operating results, which continued to be strong in 2012. In summary, the Committee considered contributions made by Mr. Laird in 2012 along with a review of broad market compensa- tion data for executives in similar roles and determined that this discretionary award was reflective of his performance in 2012. Retirement Plan Benefits The Company provides retirement benefits through the Diamond Hill Investment Group 401k Plan and Trust. The named executive officers are entitled to participate in this plan on the same terms and conditions as all other employees. The Plan does not involve any guaranteed minimum or above-market returns, as plan returns depend on actual investment results. 19 Other Benefits and Perquisites The Company does not provide supplemental retirement plan benefits or non-qualified compensation plans to the named executive officers. As a general rule, the Company does not provide any perquisites or other personal benefits to its named executive officers that are not offered on an equal basis to all employees. The Company’s named executive officers are entitled to participate in benefit programs that entitle them to medical, dental, and short-term and long-term disability insurance coverage that are available to all employees. Post Employment Payments Only the CEO has an employment contract which provides for payments upon termination of employment. More information on the employment agreement with our CEO and termination payments thereunder is set forth under the heading “Employment Agreements and Change in Control Benefits.” Stock Ownership Guidelines In February 2010, the Board adopted stock ownership guidelines for our named executive officers to further align their interests with those of shareholders. This policy provides that our named executive officers are expected to reach levels of ownership (determined as a stated multiple of base salary) within five years after the adoption of the guidelines or, if later, within five years from the date when the executive assumed his or her posi- tion. The below table provides the target ownership level and actual shares owned as of December 31, 2012. Both of our named executive officers hold shares well in excess of the amounts required under the guidelines.

Risks Related to Compensation Policies and Practices As part of its oversight of the Company’s executive and non-executive compensation programs, the Compen- sation Committee considers how current compensation programs, including the incentives created by compensa- tion awards, affect the Company’s risk profile. In addition, the Company reviews its compensation policies, particularly the incentives that they create, to determine whether they encourage an appropriate level of risk- taking and do not present a significant risk to the Company. The Compensation Committee also considered the following risk mitigating factors: • current compensation programs reward portfolio managers and research analysts on trailing five-year investment performance in client accounts; • a majority of incentive compensation is in the form of equity-based awards; • sale restriction periods for equity-based compensation awards encourage executives and other employees to focus on the long-term performance of the Company; • the Committee’s discretionary authority to adjust annual incentive awards, which helps mitigate business risks associated with such awards; • the Company’s internal controls over financial reporting and other financial, operational and compliance policies and practices currently in place; and • base salaries consistent with executives’ responsibilities so that they are not motivated to take excessive risks to achieve a reasonable level of financial security. Based on this review, the Company has concluded that its compensation policies and procedures are not reasonably likely to have a material adverse effect on the Company. 20 Compensation Recoupment and Restitution Policy Upon the recommendation of the Compensation Committee, our Board of Directors recently adopted a compen- sation recoupment and restitution policy that applies to all incentive compensation received by all associates. Under the policy, the Company may recover all or a portion of incentive compensation (or pay out additional incentive compensation) related to awards made after the adoption of the Policy, in three general situations: (1) If due to error or malfeasance the previously determined incentive pool, or an individual award, is either too large (or too small), then any overpayment made to an associate may be returned to Company or an additional payment may be made to an associate. (2) If an associate violates an important company policy or acts in an unlawful manner, then the Company could recoup the associate’s incentive compensation. (3) If an associate, who is part of the financial statement preparation process, commits wrongdoing, then the Company could recoup the associate’s incentive compensation. The policy is intended to provide enhanced safeguards against certain types of misconduct and provide enhanced protection to and alignment with shareholders. These provisions are in addition to any policies or recovery rights that are provided under applicable laws, including the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act. Starting with those paid in 2013, awards made under the 2011 Plan are subject to this policy.

The stock awards made pursuant to the 2005 Plan were based upon the achievement of a specific performance target for the Company. The per- formance target was determined at the beginning of each performance period, taking into the consideration the performance target from the prior year, forecasted revenue, and the requirements of Section 162(m) of the Internal Revenue Code.

Employment Agreements and Change in Control Benefits The Company currently has an employment agreement with Mr. Dillon. A description of the agreement is set forth below. The Company is not a party to any employment agreement with any other employees and is not obligated to provide change in control benefits to any employee other than Mr. Dillon. Employment Agreement with Mr. Dillon. In March 2011, the Company entered into an amended and restated employment agreement with Mr. Dillon, the Company’s President and CEO. The agreement has a cur- rent expiration date of January 1, 2016. The agreement provides for an annual salary of $360,000, which may be increased (but not reduced) by the Board annually, plus an annual cash bonus of at least 5% of the Company’s operating income, with a maximum annual cash bonus of $640,000 and a minimum annual cash bonus of $0. Mr. Dillon also received a restricted stock award of 100,000 shares that vests on January 1, 2016 if performance criteria established by the Compensation Committee are satisfied and Mr. Dillon remains employed by the Company on that date. The performance criteria and vesting provisions of Mr. Dillon’s restricted stock award are discussed more thoroughly in the “Compensation Discussion and Analysis” section above. Mr. Dillon’s employment agreement also entitles him to receive health insurance and six weeks paid vacation annually and participate in other benefit programs offered to employees. The agreement also restricts Mr. Dillon from compet- ing with the Company during the term of the agreement and for one year following termination of his employ- ment and provides that he will at all times maintain the confidentiality of Company information. If the Company terminates Mr. Dillon’s employment without Cause (as defined in Mr. Dillon’s amended and restated employment agreement), he would be entitled to the following payments, which are quantified to reflect the amounts he would have received had his employment been terminated at December 31, 2012: 1. his accrued but unpaid base salary and vacation and unreimbursed business expenses as of the date of termination ($0 at December 31, 2012); 2. payments, if any, under other benefit plans and programs in effect at the time ($0 at December 31, 2012. The Company has no benefit plans that would result in payments upon termination); 3. a single lump sum payment equal to six months base salary at his annual salary rate in effect at the date of termination ($180,000 at December 31, 2012); 4. beginning in the seventh month after the date of termination, six monthly payments of his monthly base salary ($180,000 at December 31, 2012); 5. any portion of the restricted stock award of 100,000 shares as provided in the award agreement those shares were granted under (40,000 shares at December 31, 2012); 6. a lump sum payment equal to the amount, if any, he received as an annual cash bonus for the preced- ing year ($640,000 at December 31. 2012); 7. his accrued but unpaid annual cash bonus from the year prior to the date of termination ($0 at December 31, 2012); and 8. a pro rata portion of the annual cash bonus ($640,000 at December 31, 2012). Mr. Dillon may terminate his employment for “Good Reason”, (as defined in Mr. Dillon’s amended and restated employment agreement) which generally includes reduction of his annual base salary or annual cash bonus, permanent or consistent assignment to him of duties inconsistent with his position and authority, no lon- ger having him report directly to the Board, or a breach by the Company of his employment agreement. If he terminates his employment for Good Reason, Mr. Dillon is entitled to all of the payments to which he would be entitled in the event he is terminated without Cause, except for the payment set forth in number 7 above. 24 If Mr. Dillon’s employment terminates due to his death or disability, upon the expiration of the employment agreement in accordance with its terms or the Company terminates Mr. Dillon for “Cause” (as defined in Mr. Dillon’s amended and restated employment agreement), he will be entitled to receive the payments set forth in numbers 1 and 2 above. In the event of his death, he will receive the payments described in numbers 1, 2, 5, and 8 above. In the event of disability, he will receive the payments described in numbers 1, 2, 5, 7, and 8 above. Under the employment agreement, “Cause” generally includes material violations of the Company’s employment policies, conviction of crime involving moral turpitude, violations of securities or investment adviser laws, caus- ing the Company to violate a law which may result in penalties exceeding $250,000, materially breaching the employment agreement, or fraud, willful misconduct, or gross negligence in carrying out his duties. In the event of a “Change in Control” (as defined in Mr. Dillon’s amended and restated employment agreement), all 100,000 shares of restricted stock would immediately vest and become transferable without restriction in accordance with the terms of the award agreement applicable to the restricted stock award. Additionally, if within 24 months after the occurrence of a “Change in Control”, Mr. Dillon’s employment is terminated by the Company for any reason other than death, disability or for Cause, or Mr. Dillon terminates his employment for “Good Reason”, he will be entitled to the following payments from us or our successor, in addi- tion to the applicable payments set forth in numbers 1 through 8 above: • a single lump sum payment equal to his annual base salary and annual cash bonus payable to him for the most recently completed fiscal year ($1,000,000 at December 31, 2012); and • a single lump sum payment equal to 12 months of premium payments for coverage for Mr. Dillon and his family under our group health plan ($5,000 at December 31, 2012). If any payments to Mr. Dillon in connection with a “Change in Control” would constitute excess parachute payments under applicable tax laws, Mr. Dillon will receive gross-up payments in an amount that covers any taxes, interest, penalties, additional taxes or costs incurred and leaves Mr. Dillon with the amount he would have retained if the payments he received upon the “Change in Control” had not constituted excess parachute pay- ments. COMPENSATION COMMITTEE REPORT The Board’s Compensation Committee has submitted the following report for inclusion in this Proxy State- ment: We have reviewed and discussed the Compensation Discussion and Analysis contained in this Proxy State- ment with management. Based on such review and discussion, we recommended that the Compensation Dis- cussion and Analysis be included in this Proxy Statement and the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Submitted by the Compensation Committee of the Board of Directors: Frances A. Skinner, Chair Donald B. Shackelford Peter J. Moran 25 PROPOSAL 2 — RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM On October 25, 2012, the Audit Committee of the Board dismissed Plante & Moran PLLC (“Plante & Moran”) as the Company’s independent registered public accounting firm. The reports of “Plane & Moran” on the consolidated financial statements of the Company for the years ended December 31, 2011 and December 31, 2010 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles. Plante & Moran’s reports on the effectiveness of internal con- trol over financial reporting as of December 31, 2011 and 2010 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. During the fiscal years ended December 31, 2010 and December 31, 2011 and from January 1, 2012 through October 30, 2012, there were (i) no disagreements between the Company and Plante & Moran on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which if not resolved to Plante & Moran’s satisfaction, would have caused Plante & Moran to make reference to the subject matter of the disagreement in connection with its reports for such years and interim period, and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K. Based on the Audit Committee’s approval and recommendation, on October 24, 2012, the Board engaged KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm for the fiscal year end- ing December 31, 2012. During the fiscal years ended December 31, 2010 and December 31, 2011 and from January 1, 2012 through October 30, 2012, neither the Company nor anyone on its behalf has consulted with KPMG regarding (i) the application of accounting principles to a specified transaction, either completed or pro- posed, (ii) the type of audit opinion that might be rendered on the Company’s financial statements, (iii) any mat- ter that was the subject of a “disagreement” within the meaning of Item 304(a)(1)(iv) of Regulation S-K, or (iv) any “reportable event” within the meaning of Item 304(a)(1)(v) of Regulation S-K. The Audit Committee has retained KPMG as the Company’s independent registered public accounting firm for the 2013 fiscal year, and is asking that our shareholders ratify this appointment. KPMG has served as our independent registered public accounting firm since October 2012. Representatives of KPMG are expected to be present at the Annual Meeting to respond to appropriate ques- tions from shareholders and to make such statements as they may desire. THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE RAT- IFICATION OF THE APPOINTMENT OF KPMG AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2013. If Proposal 2 is not approved, the Audit Committee will reconsider the appointment of KPMG as our independent registered public accounting firm for 2013.

Preapproval by Audit Committee The Audit Committee pre-approves the audit and non-audit services provided by the independent registered public accounting firm to ensure that the provision of the services does not impair the firm’s independence. All services disclosed above were pre-approved by the Audit Committee. AUDIT COMMITTEE REPORT The Audit Committee is comprised of three independent directors operating under a written charter adopted by the Board. Annually, the Audit Committee engages the Company’s independent registered public accounting firm. KPMG served as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2012. Management is responsible for preparation of the Company’s financial statements and for designing and maintaining the Company’s systems of internal controls and financial reporting processes. The Company’s independent registered public accounting firm is responsible for performing an audit of the Company’s con- solidated financial statements in accordance with standards of the Public Company Accounting Oversight Board (“PCAOB”) and issuing reports on the Company’s financial statements and the effectiveness of the Company’s internal controls over financial reporting. The Audit Committee’s responsibility is to provide independent, objective oversight of these processes. Pursuant to this responsibility, the Audit Committee met and held discussions with management and KPMG regarding the audited consolidated financial statements of the Company for the fiscal year ended December 31, 2012. The Audit Committee reviewed the audit plan and scope with KPMG and discussed with them the matters required by Statement on Auditing Standards No. 61, as amended, and adopted by the PCAOB in Rule 3200T. The Audit Committee also met with KPMG without management present to discuss the results of their audit work, their evaluation of the Company’s system of internal controls and the quality of the Company’s financial reporting. The Committee also discussed with KPMG its independence from management and the Company, and received its written disclosures and the letter from KPMG required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the audit committee concerning independence. Management has represented to the Audit Committee that the Company’s consolidated financial statements for the year ended December 31, 2012, were prepared in accordance with United States generally accepted accounting principles, and the Audit Committee reviewed and discussed the audited consolidated financial statements with management and KPMG. Based on the Audit Committee’s discussions with management and KPMG and review of KPMG’s report to the Audit Committee, the Audit Committee recommended to the Board of Directors (and the Board has approved) that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, filed with the SEC. Submitted by the Audit Committee of the Board of Directors: David P. Lauer, Chairman Bradley C. Shoup Frances A. Skinner 27 PROPOSAL 3 — ADVISORY VOTE ON THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010, requires that we provide our shareholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our executive officers identified in the Summary Compensation Table of this Proxy Statement (the “named executive officers”) as disclosed in this Proxy Statement in accordance with the SEC’s rules. As described in detail in the section entitled, “EXECUTIVE OFFICERS AND COMPENSATION INFORMATION”, we believe that executive compensation should be linked with the Company’s performance and significantly aligned with the interests of the Company’s shareholders. In addition, our executive compensa- tion program is designed to allow us to retain, and recognize the contributions of, employees who play a sig- nificant role in our current and future success. We urge you to read the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure for a detailed description of the fiscal year 2012 compensation of our named executive officers. The vote on this resolution is not intended to address any specific element of compensation; rather, the advi- sory vote relates to the overall compensation of our named executive officers. This vote is advisory and therefore not binding on the Company. However, the Board and the Compensation Committee will review the voting results and will take into account the outcome of the vote when determining future compensation for the Compa- ny’s named executive officers. Accordingly, we ask our shareholders to vote on the following resolution: “RESOLVED, that the Company’s shareholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s Proxy Statement for the 2013 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure.” THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO THE COMPENSATION DISCLOSURE RULES OF THE SEC. ADDITIONAL INFORMATION SHAREHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS Given the Company’s relatively small size, the relatively small number of record shareholders, and the Board’s consistent practice of being open to receiving direct communications from shareholders, the Board believes that it is not necessary to implement, and we do not have, a formal process for shareholders to send communications to the Board. Our practice is to forward any communication addressed to the full Board to the Chairman, to a group of directors to a member of the group, or to an individual director, to that person. SHAREHOLDER PROPOSALS FOR 2014 ANNUAL MEETING Shareholders are entitled to submit proposals on matters appropriate for shareholder action consistent with SEC rules and our Code of Regulations. Should a shareholder wish to have a proposal appear in the Proxy Statement for next year’s annual meeting, under applicable SEC rules, the proposal must be received by the Company’s Secretary on or before November 13, 2013, and must otherwise comply with the requirements of Rule 14a-8 of the Exchange Act. If a shareholder intends to present a proposal at next year’s annual meeting but does not intend to seek the inclusion of such proposal in our Proxy Statement, such proposal must be received by the Company prior to January 27, 2014, or management proxies will be entitled to use discretionary voting authority should such proposal be raised without any discussion of the matter in the Proxy Statement. The Company’s address is 325 John H. McConnell Boulevard, Suite 200, Columbus, Ohio 43215. 28 SHAREHOLDERS SHARING THE SAME ADDRESS The SEC has implemented rules regarding the delivery of proxy materials (i.e., annual reports, proxy state- ments, proxy statements combined with a prospectus or any information statements provided to shareholders) to households. This method of delivery, often referred to as “householding”, would generally permit the Company to send a single annual report and a single proxy statement to any household at which two or more different shareholders reside if the Company believes such shareholders are members of the same family, unless the shareholder(s) have opted out of the householding process. Each shareholder would continue to receive a sepa- rate notice of any meeting of shareholders and proxy card. The householding procedure reduces the volume of duplicate information you receive and reduces expenses. The Company has instituted householding. If (i) you wish to receive separate annual reports or proxy statements, either this year or in the future, or (ii) members of your household receive multiple copies of the annual report and proxy statement and you wish to request house- holding, you may contact the Company’s transfer agent, Continental Stock Transfer & Trust Company at 17 Battery Place, New York, New York 10004, or write to Mr. James Laird at 325 John H. McConnell Boulevard, Suite 200, Columbus, Ohio 43215. In addition, many brokerage firms and other holders of record have instituted householding. If your family has one or more “street name” accounts under which our shares are beneficially owned, you may have received householding information from your broker, financial institution or other nominee in the past. Please contact the holder of record directly if you have questions, require additional copies of this Proxy Statement or Annual Report on Form 10-K or wish to revoke your decision to household and thereby receive multiple copies. You should also contact the holder of record if you wish to institute householding. These options are available to you at any time. OTHER BUSINESS The Board knows of no other business to be acted upon at the Annual Meeting. However, if any other busi- ness properly comes before the Annual Meeting, it is the intention of the persons named in the enclosed Proxy to vote on such matters in accordance with their best judgment. The prompt completion, execution, and delivery of your proxy card or your submission of voting instructions electronically over the Internet or by telephone will be appreciated. Whether or not you expect to attend the Annual Meeting, please complete and sign the Proxy and return it in the enclosed envelope, or vote your proxy electronically via the Internet or telephonically.

Business Forward-Looking Statements Throughout this Annual Report on Form 10-K, Diamond Hill Investment Group, Inc. may make forward- looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, relating to such matters as anticipated operating results, pros- pects for achieving the critical threshold of assets under management, technological developments, economic trends (including interest rates and market volatility), expected transactions and acquisitions and similar matters. The words “believe,” “expect,” “anticipate,” “estimate,” “should,” “hope,” “seek,” “plan,” “intend” and similar expressions identify forward-looking statements that speak only as of the date thereof. While the Company believes that the assumptions underlying its forward-looking statements are reasonable, investors are cautioned that any of the assumptions could prove to be inaccurate and accordingly, the actual results and experiences of the Company could differ materially from the anticipated results or other expectations expressed by the Company in its forward- looking statements. Factors that could cause such actual results or experiences to differ from results discussed in the forward-looking statements include, but are not limited to: the adverse effect from a decline in the securities mar- kets; a decline in the performance of the Company’s products; changes in interest rates; changes in national and local economic and political conditions, including the effects of implementation of the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012 and the continuing economic uncertainty in various parts of the world; changes in government policy and regulation, including monetary policy; changes in the Company’s ability to attract or retain key employees; unforeseen costs and other effects related to legal proceedings or investigations of governmental and self-regulatory organizations; and other risks identified from time-to-time in the Company’s other public documents on file with the U. S. Securities and Exchange Commission (“SEC”), including those discussed below in Item 1A. When we use the terms the “Company,” “management,” “we,” “us,” and “our,” we mean Dia- mond Hill Investment Group, Inc. and its subsidiaries. Overview The Company, an Ohio corporation organized in April 1990, derives its consolidated revenue and net income from investment advisory and fund administration services provided by its subsidiaries Diamond Hill Capital Management, Inc. (“DHCM”), Beacon Hill Fund Services, Inc. (“BHFS”), and BHIL Distributors, Inc. (“BHIL”). BHFS and BHIL collectively operate as Beacon Hill. DHCM is a registered investment adviser under the Investment Advisers Act of 1940. DHCM sponsors, distributes, and provides investment advisory and related services to various U.S. and foreign clients through Diamond Hill Funds, institutional accounts, and private investment funds (generally known as “hedge funds”). Beacon Hill provides fund administration and statutory underwriting services to various clients, including Diamond Hill Funds. The Company’s primary objective is to fulfill its fiduciary duty to clients. Its secondary objective is to grow the intrinsic value of the Company in order to achieve an adequate long-term return for shareholders. Investment Advisory Activities Clients The Company provides investment advisory services to a broad range of clients, including corporations, mutual funds, retirement plans, public pension funds, endowments, foundations, financial institutions and high net worth individuals. We strive to expand our client base by attracting new clients and earning additional busi- ness from existing clients. Investment Philosophy We believe that a company’s intrinsic value is independent of its stock price. Our investment philosophy is rooted in the teachings of Benjamin Graham and the methods of Warren Buffett. The following are the guiding principles for our philosophy: • Treat every investment as a partial ownership interest in that company. Investing is most intelligent when it is most businesslike. 3 • Always invest with a margin of safety. We want to purchase securities at a sufficient discount to our estimate of intrinsic value. We estimate the intrinsic value of the business independent of the current stock market price then compare our estimate to the price in order to determine if an opportunity exists. If we do this successfully, it will both increase the potential reward and be the most effective risk control. • Possess a long-term investment temperament. In the short term, market prices are driven as much by emotion as economic fundamentals. Over time, the economic performance of the business and the price paid will determine the investment return, not the market. • Recognize that market price and intrinsic value tend to converge over a reasonable period of time. Guided by our investment philosophy, our portfolio managers invest in companies when the current market price is at a discount to our estimate of intrinsic value, based upon a discounted cash flow methodology. The investment opportunity lies in the ability to recognize when the current market price does not reflect our estimate of a company’s intrinsic value. By not relying on the market as an indicator of value, we believe the market can be used to our advantage over time. Investment Process DHCM’s investment process begins with fundamental research focusing on estimating a company’s intrinsic value independent of its current stock price. Bottom-up analysis, which takes into consideration earn- ings, revenue growth, operating margins and other economic factors, is of primary importance in estimating the intrinsic value of an individual company. A five-year discounted cash flow analysis is the primary methodology to determine whether there is a discrepancy between the current market price and DHCM’s estimate of intrinsic value. In order to forecast the amount and timing of cash flows, the research analysts concentrate on the funda- mental economic drivers of the business, including competitive positioning, quality of management, and balance sheet strength. Research analysts also evaluate each company within the context of sector and industry secular trends. Key factors in analyzing sectors and industries include relative pricing power, ability to earn excess returns, long-term capital flow, and other fundamental factors. DHCM also applies an intrinsic value philosophy to the analysis of fixed income securities. Only securities selling at a discount (premium) to intrinsic value will be purchased (sold short). A portfolio manager assigns the highest weights to the highest conviction names. A strategy will often not have any exposure to certain industries in which we are unable to find attractive opportunities. A stock will be sold if its price reaches DHCM’s estimate of intrinsic value, if fundamentals deteriorate, if a more attractive opportunity is identified, or if the holding reaches the stated limit as a percent of the portfolio. DHCM believes that many investors’ short-term focus hinders their long-term results, which creates market inefficiencies and therefore opportunities. In addition, not all investors are valuation sensitive. We believe that we can exploit these market anomalies/inefficiencies by possessing a long-term investment temperament and practicing a consistent and repeatable business appraisal approach to investing. Furthermore, DHCM believes that investing in securities whose market prices are significantly below DHCM’s estimate of intrinsic value (or selling short securities whose market prices are above DHCM’s estimate of intrinsic value) is a reliable method to achieve above average relative returns as well as mitigate risk. Investment Advisory Fees The Company’s principal source of revenue is investment advisory fee income earned from managing client accounts under investment advisory and sub-advisory agreements. The fees earned depend on the type of invest- ment strategy, account size and servicing requirements. Revenues depend on the total value and composition of assets under management (“AUM”). Accordingly, net asset flows, market fluctuations in client portfolios, and the composition of AUM impact our revenues and results of operations. The Company also has certain agree- ments which allow us to earn variable fees in the event that investment returns exceed targeted amounts during a measurement period. 4 Investment Strategies The Company offers several traditional and alternative investment strategies. All are based on the same intrinsic value philosophy. As of December 31, 2012 we offered the following investment strategies to our cli- ents: 1. Small Cap – Pursues long-term capital appreciation by investment in a portfolio of 40-70 small- capitalization U.S. companies. 2. Small-Mid Cap – Pursues long-term capital appreciation by investing in a portfolio of 40-70 small- and mid-capitalization U.S. companies. 3. Large Cap – Pursues long-term capital appreciation by investing in a portfolio of 40-60 large- capitalization U.S. companies. 4. Select – Pursues long-term capital appreciation by investing in a portfolio of 30-40 U.S. companies across a broad range of market capitalizations. 5. Long-Short – Pursues long-term capital appreciation by investing both long and selling short U.S. companies across a broad range of market capitalizations. 6. Strategic Income – Pursues high current income, preservation of capital, and total return by investing in corporate bonds across the credit spectrum. Investment Results The Company believes that one of the most important characteristics exhibited by the best investment firms is excellent investment returns for their clients over a long period of time. The Company is pleased that, during its history as an investment advisory firm, it has delivered what it believes are strong long-term investment returns for its clients. Investment returns have been a key driver in the long-term success the Company has ach- ieved in growing AUM. Despite strong absolute equity market returns, the past three-year period has been a difficult one for many active money managers, including DHCM. Our equity strategy returns trailed benchmark returns over the same period; however, we remain focused on five-year periods to evaluate our results. Sig- nificant exposure to the energy sector across all of our equity strategies was the primary driver of under- performance relative to the benchmarks over the one- and three-year periods ended December 31, 2012. The energy sector was the worst performing sector in the market in 2012 as continued domestic oil and gas supply increases from hydraulic fracturing technology and weaker global demand for oil, driven by slowdowns in Europe and China, created headwinds for energy stocks. We believe this underperformance over the trailing one- and three-year periods contributed to the flat and negative client cash flows in 2011 and 2012, respectively. The following is a summary of the investment returns as of December 31, 2012, relative to respective passive bench- mark. 5 Inception 1 Year 3 Year 5 Year 10 Year Inception As of December 31, 2012 12/29/2000 12/30/2005 6/29/2001 12/1/2005 6/30/2000 13.17% 9.14% 4.57% 11.05% 10.41% 16.35% 12.25% 3.56% 9.72% 6.21% 5.92% 15.74%11.16% 6.40% N/A 17.88% 13.34% 4.34% N/A 5.52% 12.62% 8.23% 1.86% 9.59% 6.18% 16.42% 11.12% 1.92% 7.52% 3.73% 4.00% 11.54% 6.63% 1.70% N/A 4.34% 16.42% 11.20% 2.04% N/A 8.77% 3.97% 0.39% 8.06% 6.16% 9/30/2002 8.11% 5.78% 1.66% 4.87% 2.43% 9.83% 9.66% 8.38% 7.75% 8.02% 4.43% 6.24% 6.03% 5.26% 5.29% 11.37% 9.62% 8.14% 7.19% 7.41% Diamond Hill Small Cap Fund Russell 2000 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Once the Company determines that the size of any of its strategies hinders its ability to add value over a passive alternative, the Company will close those strategies to new clients, which may impact the Company’s ability to grow AUM. The Small Cap strategy was closed to new investors as of December 31, 2005 and re-opened on September 1, 2007. The Long-Short strategy was closed to new investors as of June 30, 2008 and re-opened on December 31, 2008. The Company estimates its AUM capacity to be approximately $20—$30 billion with AUM of $9.4 billion as of December 31, 2012. The key consideration in determining AUM capacity involves looking at each of our investment strategies and estimating its individual capacity, given market capitalization constraints. Distribution Channels The Company’s investment advisory services are distributed through multiple channels. Our institutional sales efforts include building relationships with institutional consultants and also establishing direct relationships with institutional clients. Our sales efforts for the Diamond Hill Funds (the “Funds”) include wholesaling to third-party financial intermediaries, including independent registered investment advisors, brokers, financial planners, and wealth advisers, who utilize the Funds in investment programs they construct for their clients. 7 AUM by Channel Below is a summary of the assets by distribution channel for the past five years ended December 31, 2012: (in millions) Proprietary funds: Assets by Distribution Channel As of December 31, 2012 2011 2010 2009 2008 Registered investment advisors . . . . . . . . . . . . . . . . . . . . . .

We will continue to be focused on the development of distribution channels to enable us to offer our various investment strategies to a broad array of clients. We intend to continue to grow assets under management through our proprietary funds and institutional accounts. We have a targeted strategic business plan to further penetrate our existing distribution channels. Our business develop- ment efforts are focused on expanding the institutional consultant channel and plan sponsor network on the sepa- rate account side, as well as our intermediary network on the fund side. Fund Administration Activities Fund Administration Services DHCM and Beacon Hill provide fund administration services to Diamond Hill Funds and other third party mutual fund companies and investment advisers. Fund administration services are broadly defined as portfolio and regulatory compliance, treasury and financial oversight, statutory underwriting, oversight of back-office services providers such as the custodian, fund accountant, and transfer agent, and general business management of the mutual fund complex. These services are offered on a stand-alone basis, as well as through a series trust or “umbrella trust” whereby individual investment advisers can establish a mutual fund under a fund complex spon- sored by the Company. Fund Administration Fees The Company earns revenue from performing various fund administration activities described above under individual client agreements. The fees earned depend on the type of service, fund size, and/or servicing require- ments. Certain client agreements have a fixed fee arrangement while others have a fee derived as a percentage of assets under administration. 8 Competition Competition in the area of investment management and fund administration is intense, and the Company’s competitors include investment management firms, broker-dealers, banks and insurance companies, some of whom offer various investment alternatives. Many competitors are better known than the Company, offer a broader range of investment products and have more offices, employees and business development representa- tives. The Company competes primarily on the basis of philosophy, performance and client service. Regulation The Company and its business are subject to various federal, state and foreign laws and regulations. As a matter of public policy, regulatory bodies are charged with safeguarding the integrity of the securities and other financial markets and with protecting the interests of participants in those markets, including investment advisory clients and shareholders of investment funds. Under these laws and regulations, agencies that regulate investment advisers have broad administrative powers, including the power to limit, restrict or prohibit an investment adviser from carrying on its business in the event the adviser fails to comply with such laws and regulations. Possible sanctions that may be imposed include civil and criminal liability, the suspension of individual employees, limi- tations on engaging in certain lines of business for specified periods of time, revocation of investment adviser and other registrations, censures and fines. DHCM is registered with the SEC under the Investment Advisers Act of 1940 (the “Advisers Act”) and operates in a highly regulated environment. The Advisers Act imposes numerous obligations on registered investment advisers, including fiduciary duties, recordkeeping requirements, operational requirements and dis- closure obligations. All Diamond Hill Funds are registered with the SEC under the Investment Company Act of 1940 and are required to make notice filings with all states where they are offered for sale. Virtually all aspects of the Company’s investment management business are subject to various federal and state laws and regulations. BHIL is registered with the SEC as a broker/dealer and is a member of the Financial Industry Regulatory Author- ity, Inc. (“FINRA”). To the extent that DHCM is a “fiduciary” under the Employment Retirement Act of 1974 (“ERISA”) with respect to benefit plan clients, it is subject to ERISA, and to regulations promulgated thereunder. ERISA and applicable provisions of the Internal Revenue Code impose certain duties on persons who are fiduciaries under ERISA, prohibit certain transactions involving ERISA plan clients, and provide monetary penalties for violations of these prohibitions. The Department of Labor, which administers ERISA, has been increasingly active in pro- posing and adopting regulations affecting the asset management industry. Failure to comply with these require- ments could have a material adverse effect on our business. The Company’s trading activities for client accounts are regulated under the Securities Exchange Act of 1934 (the “Exchange Act”), as well as the rules of various FINRA, including laws governing trading on inside information, market manipulation and a broad number of trading requirements (e.g., volume limitations, report- ing obligations) and market regulation policies in the United States. The financial services industry has been the subject of intense regulatory scrutiny in recent years. Our busi- ness has been subject to increasing regulation in the United States and other countries, and we expect this trend to continue in the future. In particular, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), which was enacted in July 2010, significantly altered the financial regulatory regime within which we operate. The Dodd-Frank Act is expansive in scope and the implications of the Act for our business will depend to a large extent on the rules that remain to be adopted by the SEC and other regulatory agencies implementing the legislation. Some of the aspects of the Dodd-Frank Act have already been implemented. Other aspects will be established over the next several years. It is difficult to predict the ultimate effects that the Dodd- Frank Act, or subsequent implementing regulations and decisions, will have upon our business and results of operations. The Dodd-Frank Act and its regulations, other new laws or regulations, changes in rules promulgated by either the SEC or other federal and state regulatory authorities or self-regulatory bodies, or changes in the interpretation or enforcement of existing laws and rules could materially and adversely impact the scope or profitability or our business. We will continue to assess our business, risk management, and compliance practices to conform to developments in the regulatory environment. 9 The preceding descriptions of the regulatory and statutory provisions applicable to us are not complete and are qualified in their entirety by reference to their respective statutory or regulatory provisions. Contractual Relationships with the Diamond Hill Funds The Company is very dependent on its contractual relationships with the Funds. In the event the Company’s advisory or administration agreements with the Funds are terminated, not renewed, or amended to reduce fees, the Company could be materially and adversely affected. The Company generated approximately 65%, 61% and 66% of its 2012, 2011 and 2010 revenues, respectively, from its advisory and administrative contracts with the Funds. The Company considers its relationship with the Funds and their board of trustees to be good, and it has no reason to believe that these advisory or administration contracts will not be renewed in the future; however, there is no assurance that the Funds will choose to continue their relationships with the Company. Please refer to Item 1A on page 12 of this report. Employees As of December 31, 2012, the Company and its subsidiaries employed 79 full-time equivalent employees. As of December 31, 2011, the comparable number was 73. The Company believes that its relationship with its employees is good and does not anticipate any material change in the number of employees. SEC Filings The Company maintains an Internet website at www.diamond-hill.com. Annual reports on Form 10-K, quar- terly reports on Form 10-Q, XBRL instance documents, current reports on Form 8-K and amendments to those reports, filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, are made available free of charge, on or through the Company’s website, as soon as reasonably practicable after such material is electroni- cally filed with, or furnished to, the SEC. The contents of the Company’s website are not incorporated into, or otherwise made a part of, this Annual Report on Form 10-K. 10 ITEM 1A. Risk Factors The Company’s future results of operations, financial condition, liquidity, and the market price of the Company’s common shares are subject to various risks, including those mentioned below and those that are dis- cussed from time-to-time in the Company’s other periodic filings with the SEC. Investors should carefully consider these risks, along with the other information contained in this report, before making an investment deci- sion regarding the Company’s common shares. There may be additional risks of which the Company is currently unaware, or which it currently considers immaterial. The occurrence of any of these risks could have a material adverse effect on the Company’s financial condition, results of operations, liquidity, and value of its common shares. Also see “Forward Looking Statements” within Item 1 of Part I of this Form 10-K. Poor investment results of the Company’s products could affect its ability to attract new clients or reduce the amount of assets under management, potentially negatively impacting revenue and net income. If the Company fails to deliver acceptable investment results for its clients, both in the short and long term, it will likely experience diminished investor interest and potentially a diminished level of AUM. The Company’s success depends on its key personnel, and its financial performance could be negatively affected by the loss of their services. The Company’s success depends on highly skilled personnel, including portfolio managers, research ana- lysts, and management, many of whom have specialized expertise and extensive experience in the investment management industry. Financial services professionals are in high demand, and the Company faces significant competition for qualified employees. With the exception of the Chief Executive Officer, key employees do not have employment contracts and generally can terminate their employment at any time. The Company cannot assure that it will be able to retain or replace key personnel. In order to retain or replace its key personnel, the Company may be required to increase compensation, which would decrease net income. The loss of key person- nel could damage the Company’s reputation and make it more difficult to retain and attract new employees and clients. A loss of client assets resulting from the departure of key personnel would decrease the Company’s rev- enues and net income, possibly materially. The Company’s AUM, which impacts revenue, is subject to significant fluctuations. Substantially all revenue for the Company is calculated as a percentage of AUM or is related to the general performance of the equity securities market. A decline in securities prices (such as that experienced during the last half of 2008 and first quarter of 2009) or in the sale of investment products, or an increase in fund redemptions, generally would reduce fee income. Financial market declines would generally negatively impact the level of the Company’s AUM and consequently its revenue and net income. A recession or other economic or political events, both in the United States as well as globally, could also adversely impact the Company’s rev- enue, if such events led to a decreased demand for products, a higher redemption rate, or a decline in securities prices. The investment results and/or the growth in the Company’s AUM may be constrained if appropriate investment opportunities are not available or if the Company closes certain of its portfolios. The Company’s ability to deliver strong investment results depends in large part on its ability to identify appropriate investment opportunities in which to invest client assets. If the Company is unable to identify suffi- cient investment opportunities for existing and new client assets on a timely basis, its investment results could be adversely affected. The risk that appropriate investment opportunities may be unavailable is influenced by a number of factors, including general market conditions, and is likely to increase if the Company’s AUM increases rapidly. In addition, if the Company determines that sufficient investment opportunities are not avail- able for a portfolio strategy, or the Company believes that in order to continue to produce attractive returns from a portfolio, the Company will consider closing the portfolio to new investors. If the Company misjudges the point at which it would be optimal to close a portfolio, the investment results of the portfolio could be negatively impacted. 11 The Company is subject to substantial competition in all aspects of its business. The Company’s investment products compete against a number of investment products and services from: • asset management firms; • mutual fund companies; • commercial banks and thrift institutions; • insurance companies; • exchange traded funds; • hedge funds; and • brokerage and investment banking firms. Many of these financial institutions have substantially greater resources than the Company and may operate in more markets or offer a broader range of products, including passively managed or “index” products. Some of these institutions operate in a different regulatory environment, which may give them certain competitive advan- tages in the investment products and portfolio structures that they offer. The Company competes with other pro- viders of investment services primarily based upon its philosophy, performance and client service. Some institutions have a broad array of products and distribution channels that make it more difficult for the Company to compete with them. If current or potential customers decide to use one of the Company’s competitors, the Company could face a significant decline in market share, AUM, revenues, and net income. If the Company is required to lower its fees in order to remain competitive, its net income could be significantly reduced because some of its expenses are fixed, especially over shorter periods of time, and other expenses may not decrease in proportion to the decrease in revenues. The loss of access to or increased fees required by third party distribution sources to market the Company’s port- folios and access the Company’s client base could adversely affect the Company’s results of operations. The Company’s ability to attract additional assets to manage is dependent on the Company’s access to third- party intermediaries. The Company gains access to mutual fund investors and some retail and institutional clients through third parties, including mutual fund platforms and financial intermediaries. The Company compensates intermediaries for access to investors and for various services provided. These distribution sources and client bases may not continue to be accessible to the Company for reasonable terms, or at all. Limiting or the total absence of such access could have an adverse effect on the Company’s results of operations. The recent economic downturn and consolidation in the broker-dealer industry may lead to reduced distribution access and increases in fees the Company is required to pay to intermediaries. If such increased fees should be required, refusal to pay them could restrict the Company’s access to those client bases while paying them could adversely affect the Company’s profitability. A significant portion of the Company’s revenues are based on contracts with the Diamond Hill Funds that are subject to termination without cause and on short notice. The Company is very dependent on its contractual relationships with the Funds. In the event the Company’s advisory or administration agreements with the Funds are terminated, not renewed, or amended to reduce fees, the Company would be materially and adversely affected. Generally, these agreements are terminable by either party upon 60 days written notice without penalty. The agreements are subject to annual approval by either (i) the board of trustees of the Funds or (ii) a vote of the majority of the outstanding voting securities of each Fund. The agree- ments automatically terminate in the event of their assignment by either the Company or the Fund. The Company generated approximately 65%, 61% and 66% of its 2012, 2011 and 2010 revenues, respectively, from its advisory and administrative contracts with the Funds, including 28%, 13%, and 10% from the advisory contracts with the Diamond Hill Long-Short Fund, Large Cap Fund, and Small Cap Fund, respectively, during 2012. The loss of the Long-Short Fund, Large Cap Fund, or Small Cap Fund contracts would have a material adverse effect on the Company. The Company considers its relationship with the Funds and their board of trustees to be good, and it has no reason to believe that these advisory or administration contracts will not be renewed in the future; however, there is no assurance that the Funds will choose to continue their relationships with the Company. 12 Operational risks may disrupt the Company’s business, result in losses or limit the Company’s growth. The Company is dependent on the capacity and reliability of the communications, information and technol- ogy systems supporting its operations, whether developed, owned and operated by the Company or by third par- ties. Operational risks such as trading or operational errors or interruption of our financial, accounting, trading, compliance and other data processing systems could result in a disruption of the Company’s business, liability to clients, regulatory intervention or reputational damage, and thus adversely affect the Company’s business. The Company’s business is subject to substantial governmental regulation. The Company’s business is subject to a variety of federal securities laws, including the Investment Advisers Act of 1940, the Investment Company Act of 1940, the Securities Exchange Act of 1934, the Sarbanes-Oxley Act of 2002, and the U.S. Patriot Act of 2001. In addition, the Company is subject to significant regulation and over- sight by the SEC and FINRA. Changes in legal, regulatory, accounting, tax and compliance requirements could have a significant effect on the Company’s operations and results, including but not limited to increased expenses and reduced investor interest in certain funds and other investment products offered by the Company. The Com- pany continually monitors legislative, tax, regulatory, accounting, and compliance developments that could impact its business. The Company will continue to seek to understand, evaluate and when possible, manage and control these and other business risks. ITEM 1B. Unresolved Staff Comments None. ITEM 2. Properties The Company leases approximately 25,500 square feet of office space at two locations in Columbus, Ohio. The Company does not own any real estate or interests in real estate. ITEM 3. Legal Proceedings From time to time, the Company is party to ordinary routine litigation that is incidental to its business. There are currently no material legal proceedings. ITEM 4. Mine Safety Disclosures None. 13 PART II ITEM 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities The following performance graph compares the total shareholder return of an investment in the Company’s common shares to that of the Russell Microcap® Index, and to a peer group index of publicly traded asset manage- ment firms for the five-year period ending on December 31, 2012. The graph assumes that the value of the invest- ment in the Company’s common shares and each index was $100 on December 31, 2007. Total return includes reinvestment of all dividends. The Russell Microcap® Index makes up less than 3% of the U.S. equity market and is a market-value-weighted index of the smallest 1,000 securities in the small-cap Russell 2000® Index plus the next 1,000 smallest securities. Peer Group returns are weighted by the market capitalization of each firm at the beginning of the measurement period. The historical information set forth below is not necessarily indicative of future performance.

Management’s Discussion and Analysis of Financial Condition and Results of Operations In this section, the Company discusses and analyzes the consolidated results of operations for the past three fiscal years and other factors that may affect future financial performance. This discussion should be read in conjunction with the Company’s Consolidated Financial Statements, Notes to Consolidated Financial Statements, and Selected Financial Data contained in this Form 10-K. Business Environment Despite the uncertainty leading up to the November elections and the looming “fiscal cliff”, the U.S. mar- kets were viewed as a safe haven amid global worries, and the S&P 500 Index finished 2012 with a 16.0% total return. U.S. corporate profit margins remained near record levels fueling stock price gains. Globally, Europe’s debt crisis was unresolved, China’s economy showed signs of slowing, and conflict threatened the Middle East two years after the Arab Spring uprising. However, investors continued to be reluctant to fully commit to stocks as evidenced by continued net flows from equity mutual funds and into bond mutual funds. Cumulative Net Flows into Equity vs. Bond Mutual Funds $BN, 2008 - Nov 2012 1,200 1,000 800 600 400 200 0 -200 -400 -600 '08 '09 '10 '11 '12 Source: Strategas Research Partners 16 Bond 1071.5 Equity -503.1 '13 With interest rates at near record lows, investors were almost singularly focused on yield in 2012. Many investors turned to higher-yielding and riskier securities in search of yield. CCC-rated corporate bonds generated an 18.3% total return in comparison to a 3.8% total return from the 10-year. U.S. investment-grade corporate bond funds received $131 billion in new assets in 2012 compared to $75 billion in 2011, and high-yield bond fund flows more than doubled from 2011 levels. Investors’ search for yield was also reflected in equity fund flows. Equity income funds collected $21 billion in assets, partially offsetting the net negative flows from all U.S. stock funds in 2012. The U.S. economy continues to show modest signs of recovery including a steady recovery in housing, and consumer discretionary spending continues to benefit from various government initiatives largely mitigating the effects of sluggish unemployment and continued household deleveraging. Consumer debt service levels are very low which is a positive; however, current debt service levels are largely linked to low interest/mortgage rates which may present a longer-term risk if rates rise. Household debt as a percent of disposable income has declined meaningfully but remains well above long-term averages. We continue to believe that the U.S. economy will be challenged for many years by financial deleveraging and the ultimate withdrawal of fiscal and monetary stim- ulus. While the U.S. faces fiscal and monetary headwinds, we believe the U.S. is still well positioned relative to other countries. From current levels, we believe equity market returns will be positive but modestly below historical average returns over the next five years. It is our expectation that we can achieve better than market returns over the next five years through active portfolio management and stock selection. Substantially all revenue for The Company is calculated as a percentage of AUM and is therefore impacted by the overall business and economic environment described above. Financial market declines or deterioration in the economic environment would generally negatively impact the level of the Company’s AUM and con- sequently its revenue and net income. Key Financial Performance Indicators There are a variety of key performance indicators the Company monitors in order to evaluate its business results. The following table presents the results of certain key performance indicators over the past three years: For the Years Ended December 31, 2012 2011 2010 Ending AUM (in millions) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Investment advisory and administration fees paid to the Company are generally based on the value of the investment portfo- lios managed by the Company and fluctuate with changes in the total value of the AUM. Such fees are recog- nized in the period that the Company manages these assets. The Company’s primary expense is employee compensation and benefits. 17 Revenues are highly dependent on both the value and composition of AUM. The following is a summary of the Company’s AUM by product, investment objective, and a roll-forward of the change in AUM for the years ended December 31, 2012, 2011, and 2010: (in millions) Assets Under Management by Product As of December 31, 2012 2011 2010 Proprietary funds . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

See Use of Supplemental Data as Non-GAAP Performance Measure on page 25 of this report. Year Ended December 31, 2012 compared with Year Ended December 31, 2011 The Company posted net income of $16.9 million ($5.44 per diluted share) for the year ended December 31, 2012, compared with net income of $14.4 million ($4.86 per diluted share) for the year ended December 31, 2011. Operating income increased by $1.4 million from 2011 to 2012 primarily due to an increase in AUM, resulting in a $2.8 million increase in revenue. The revenue increase was offset by an increase in operating expenses of $1.4 mil- lion, primarily related to higher compensation related to staffing increases. A positive return on the Company corporate investments and a change in the effective tax rate from 37.6% in 2011 to 35.1% in 2012 due to a reduction of certain tax accruals further contributed to the overall increase in net income. Operating profit margin increased to 36.7% for 2012 from 36.1% for 2011. The Company expects that its operating margin will fluctuate from year to year based on various factors including revenues; investment results; employee performance; staffing levels; devel- opment of investment strategies, products, or channels; and industry comparisons. Year Ended December 31, 2011 compared with Year Ended December 31, 2010 The Company posted net income of $14.4 million ($4.86 per diluted share) for the year ended December 31, 2011, compared with net income of $12.4 million ($4.48 per diluted share) for the year ended December 31, 2010. While net income increased $2.0 million, revenue for the period increased $7.1 million offset by a $2.5 million increase in operating expenses, a $1.3 million decrease in net investment income, and a $1.4 million increase in the income tax provision from 2010 to 2011. Operating profit margin increased to 36.1% for 2011 from 32.6% for 2010. Revenue (in thousands) 2012 2011 % Change 2011 2010 % Change Investment advisory . . . . . . . . . . . . . . . . . . . . . .

This compared to 88% and 12%, respectively, for 2011. Investment Advisory Fees. Investment advisory fees increased by $1.8 million, or 3%. Investment advi- sory fees are calculated as a percentage of average net AUM at various rates depending on the investment prod- uct. While the average AUM increased 5% year over year, the average advisory fee rate declined one basis point to 0.62% for the year ended December 31, 2012 compared to 0.63% for the year ended December 31, 2011. Contributing to the decrease in the average advisory fee rate is the large cap fee reduction where the Company voluntarily lowered the investment advisory fee it charges on the Diamond Hill Large Cap Fund and certain large cap separate accounts by 0.05% effective October 1, 2011. The large cap strategy fees were reduced to better align the Company’s investment advisory fees with its investment management goals. Mutual Fund Administration Fees. Mutual fund administration fees increased $1.0 million, or 13%, during 2012. Mutual fund administration fees include administration fees received from Diamond Hill Funds, which are calculated as a percentage of average mutual fund AUM, and all Beacon Hill fee revenue. The increase in the mutual fund administration fee is due to a 13% increase in average mutual fund AUM from $4.2 billion for the year ended December 31, 2011 to $4.8 billion for the year ended December 31, 2012 while the overall blended net administration fee rate remained flat at 0.15% year over year. Revenue for the Year Ended December 31, 2011 compared with Year Ended December 31, 2010 As a percent of total 2011 revenues, investment advisory fees accounted for 88% and mutual fund admin- istration fees made up the remaining 12%. This compared to 87% and 13%, respectively, for 2010. Investment Advisory Fees. Investment advisory fees increased by $6.8 million, or 14%. Investment advisory fees are calculated as a percentage of average net AUM at various levels depending on the investment product. The Company’s average advisory fee rate for 2011 was 0.63% compared to 0.70% in 2010. The decrease in the average advisory fee rate is due to a continued change in the overall composition of AUM first seen during 2008, where long- short strategies, which pay a higher advisory fee rate, made up 24% of total AUM as of fourth quarter 2011 compared to 35% of total AUM as of first quarter 2010 while long only strategies, which pay a lower advisory fee rate, made up 60% of total AUM as of fourth quarter 2011 compared to 50% of total AUM as of first quarter 2010. Further con- tributing to the decrease in the average advisory rate is the large cap fee reduction where the Company voluntarily lowered the investment advisory fee it charges on the Diamond Hill Large Cap Fund and certain large cap separate accounts by 0.05% effective October 1, 2011. Despite the 0.07% decrease in the average advisory fee rate during 2011 compared to 2010, the fee rate was being charged on a greater asset base as the average AUM increased 26% during the year compared to 2010 resulting in an increase in the overall fees earned during 2011. Mutual Fund Administration Fees. Mutual fund administration fees increased $367 thousand, or 5%, during 2011. Mutual fund administration fees include administration fees received from Diamond Hill Funds, which are calculated as a percentage of average mutual fund AUM, and all Beacon Hill fee revenue. The increase in the mutual fund administration fee is due to a 11% increase in average mutual fund AUM from $3.8 billion for the year ended December 31, 2010 to $4.2 billion for the year ended December 31, 2011 offset by a decrease in the overall blended net administration fee rate from 0.17% for the year ended December 31, 2010 to 0.15% for the year ended December 31, 2011.

Employee compensation and benefits increased by $993 thousand, or 3%, primarily due to an increase of $1.5 million in salaries and related benefits due to an increase in staffing levels, offset by a decrease of $511 thousand in incentive compensation during the year ended December 31, 2012 compared to the year ended December 31, 2011. General and Administrative. General and administrative expenses increased by $236 thousand, or 5%, from 2011 to 2012. This increase is primarily due to additional research expenses to support the Company’s investment team, an increase in general system and information technology expenses, additional rent related to the expansion of the Company’s office space during third quarter 2011, and employee professional development, offset by a reduction in corporate legal expenses and a decrease in non-income related taxes. Sales and Marketing. Sales and marketing expenses increased by $245 thousand, or 21%, from 2011 to 2012. This increase was primarily due to an overall increase in travel and other expenses related to business development and retention efforts during 2012. Third Party Distribution. Third party distribution expense represents payments made to intermediaries related to sales of the Company’s investment products. This expense is directly correlated with investments in the Company’s proprietary funds. The period-over-period change directly corresponds to the change in investment advisory fees earned by the Company related to those products. Mutual Fund Administration. Mutual fund administration expenses increased by $53 thousand, or 4%, from 2011 to 2012. The majority of mutual fund administration fees are variable based upon the amount of mutual fund AUM or the number of shareholder accounts. While average mutual fund AUM increased by 13% from 2011 to 2012, this increase in the expense was offset due to a shift in the servicing of shareholder accounts from the fund’s transfer agent to omnibus shareholder accounting at third party intermediaries. The costs asso- ciated with servicing these shareholder accounts are now reflected as Fund Related Expenses (see Footnote 2: Revenue Recongition – Fund Administration). Expenses for the Year Ended December 31, 2011 compared with Year Ended December 31, 2010 Compensation and Related Costs. Employee compensation and benefits increased by $1.9 million, or 6%, primarily due to an increase of $1.7 million in incentive compensation during 2011 consistent with fluctua- tions in AUM during the year and the associated increase in operating income. In addition, salaries and related benefits increased $180 thousand due to increases in the costs of benefits along with fluctuations in staffing lev- els during the year. General and Administrative. General and administrative expenses increased by $1.0 million, or 30%, from 2010 to 2011. This increase is primarily due to additional research expenses to support the Company’s investment team, the implementation of new systems and other information technology expenses, increased product development expenses, and expansion of the Company’s office space. Sales and Marketing. Sales and marketing expenses increased by $291 thousand, or 34%, from 2010 to 2011. This increase was primarily due to a continued increased presence at industry conferences and an overall increase in travel and other expenses related to business development and retention efforts during the year. Third Party Distribution. Third party distribution expense represents payments made to intermediaries related to sales of the Company’s investment products. This expense directly correlated with investments in the Company’s private investment funds. The period-over-period increase or decrease directly corresponds to the increase or decrease in investment advisory fees earned by the Company related to those products. Mutual Fund Administration. Mutual fund administration expenses decreased by $437 thousand, or 23%, from 2010 to 2011. The majority of mutual fund administration fees are variable based upon the amount of mutual fund AUM. Despite an overall increase in average mutual fund AUM by 11% from 2010 to 2011, the decrease in mutual fund administration expense was primarily due to third party service provider fee reduction effective during fourth quarter 2010 and a further fee reduction during fourth quarter 2011. 21 Beacon Hill Fund Services Beacon Hill is currently staffed with 10 full-time equivalent employees, and provides compliance, treasurer, and other fund administration services to mutual fund clients and their investment advisers. In addition, through its registered broker/dealer, Beacon Hill also serves as the underwriter for a number of mutual funds. The follow- ing is a summary of Beacon Hill’s performance for the year ended December 31, 2012 compared to 2011 and 2010, excluding 12b-1/service fees and commission revenue and expenses, which net to zero: (in thousands) For the Year Ended December 31, 2012 2011 2010 Revenue1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

These amounts have been eliminated from the Consolidated Statements of Income. Liquidity and Capital Resources Sources of Liquidity Our main source of liquidity is cash flow from operating activities which are generated from investment advisory and fund administration fees. The Company’s entire investment portfolio is in readily marketable secu- rities, which provide for cash liquidity, if needed. Investments in mutual funds are valued at their quoted current net asset value. Investments in private investment funds are valued independently based on readily available market quotations. Inflation is expected to have no material impact on the Company’s performance. Cash and cash equivalents, accounts receivables, and investments represent approximately 84% and 89% of total assets as of December 31, 2012 and 2011 respectively. The Company believes these sources of liquidity as well as our continuing cash flows from operating activities will be sufficient to meet our current and future operating needs for at least the next 12 months. Uses of Liquidity In line with the Company’s primary objective to fulfill its fiduciary duty to clients and secondary objective to achieve an adequate long-term return for shareholders, the Company anticipates the main uses of cash will be operating expenses. The Board of Directors and management continually review various factors to determine whether the Company has capital in excess of that required for the business and the appropriate use of any excess capital. The factors considered include the Company’s investment opportunities, the Company’s risks, and future dividend and capital gain tax rates. Evaluating management’s stewardship of capital for shareholders is a central part of our investment discipline that we practice for our clients. We hold ourselves to the same standard that we look for when evaluating investments for our clients. While this is the fifth consecutive year that the company has paid a special dividend, there can be no assurance that the company will pay a dividend in the future. The Company has paid out special dividends totaling $46.00 per share from 2008 through 2012. These special dividends reduced shareholders’ equity by $127 million over the past five years. The 2012 special dividend reduced shareholders’ equity by $25.2 million. A portion of the 2012 dividend was a return of capital for tax purposes and the Company elected to record the dividend as a reduction of retained earnings consistent with prior years, which contributed to the accumulated deficit of $28.7 million as of December 31, 2012. The Company’s accumulated deficit is not expected to impact its future ability to operate given its total shareholder equity, continuing profitability and strong cash and financial position. The 2011 special dividend reduced shareholders’ 22 equity by $14.9 million. It was a qualified dividend for tax purposes and was recorded as a reduction of retained earn- ings, which contributed to the accumulated deficit of $20.4 million as of December 31, 2011. The 2010 special divi- dend reduced shareholders’ equity by $36.3 million and was recorded through retained earnings generating an accumulated deficit of $19.8 million as of December 31, 2010. The 2009 special dividend reduced shareholders’ equity by $26.2 million and was recorded through retained earnings. A portion of the 2010 and 2009 dividend was a return of capital for tax purposes and the Company elected to record each dividend as a reduction of retained earnings. The 2008 special dividend reduced shareholders’ equity by $24.4 million and was recorded through common stock as 100% of this dividend represented a return of capital to shareholders. Working Capital As of December 31, 2012, the Company had working capital of approximately $17.6 million compared to $14.2 million at December 31, 2011. Working capital includes cash, securities owned and current receivables, net of all liabilities. On December 5, 2012, the Company’s board of directors declared an $8.00 per share dividend payable on December 21, 2012 to shareholders of record on December 17, 2012. The payment of the special cash dividend reduced the Company’s working capital balance. The Company has no debt, and believes its available working capital is sufficient to cover current expenses. The Company does not expect any material capital expenditures dur- ing 2013. Cash Flow Analysis Cash Flows from Operating Activities The Company’s cash flows from operating activities are calculated by adjusting net income to reflect other significant operating sources and uses of cash, certain significant non-cash items such as share-based compensa- tion, and timing differences in the cash settlement of operating assets and liabilities. As of December 31, 2012, 2011, and 2010, net cash provided by operating activities totaled $24.5 million, $22.7 million, and $26.0 million, respectively. The changes in net cash provided by operating activities generally reflects net income plus the effect of non-cash items and the timing differences in the cash settlement of assets and liabilities. Cash Flows from Investing Activities The Company’s cash flows from investing activities consist primarily of capital expenditures and the pur- chase and redemption of the Company’s investment portfolio. Cash flows used in investing activities totaled $7.4 million for the year ended December 31, 2012 and pri- marily related to the purchase of corporate investments. Cash flows provided by investing activities totaled $2.9 million for the year ended December 31, 2011. The Company redeemed $4.1 million from its corporate invest- ments generating cash offset by $926 thousand in corporate investments purchased during 2011. Cash flows provided by investing activities totaled $4.7 million for the year ended December 31, 2010. The Company redeemed $6.0 million from its corporate investments generating cash offset by $1.3 million in corporate invest- ments purchased during 2011. Cash Flows from Financing Activities The Company’s cash flows from financing activities consist primarily of the payment of special dividends, the repurchase of common shares, and the payment of taxes withheld on employee stock transactions offset by the proceeds from the issuance of common stock. As of December 31, 2012, 2011, and 2010, net cash used by financing activities totaled $24.5 million, $16.2 million, and $36.4 million, respectively. The primary cash flows used in financing activities for the periods were special dividends of $25.2 million, $15.0 million, and $36.3 million, respectively. During 2011, the Company repurchased $1.1 million in common shares pursuant to the share repurchase program announced on August 9, 2007. No shares were repurchased during 2012 or 2010. 23 Selected Quarterly Information Unaudited quarterly results of operations for the years ended December 31, 2012 and 2011 is summarized below: (in thousands, except per share data) 12/31 09/30 06/30 03/31 12/31 09/30 06/30 03/31 Assets under management At or For the Quarter Ended 2012 2011 (in millions) . . . . . . . . . . . . . . $ 9,429 $ 9,681 $ 9,164 $ 9,360 $ 8,671 $ 7,719 $ 9,186 $ 9,250 16,450 11,001 Total revenue . . . . . . . . . . . . . . .

The Company defines “net operating income after tax” as the Company’s net operating income less income tax provision excluding investment income and the tax impact related to the investment income. The Company believes that “net operating income after tax” provides a good representation of the Company’s operating per- formance, as it excludes the impact of investment income on financial results. The amount of the investment portfolio and market fluctuations on the investments can change significantly from one period to another, which can distort the underlying earnings potential of a company. We also believe “net operating income after tax” is an important metric in estimating the value of an asset management business. This non-GAAP measure is provided in addition to net income and net operating income and is not a substitute for net income or net operating income and may not be comparable to non-GAAP performance measures of other companies. 24 (in thousands, except per share data) Net operating income, GAAP basis . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Off-Balance Sheet Arrangements The Company has no off-balance sheet arrangements. It does not have any obligation under a guarantee contract, or a retained or contingent interest in assets or similar arrangement that serves as credit, liquidity or market risk support for such assets, or any other obligation, including a contingent obligation, under a contract that would be accounted for as a derivative instrument or arising out of a variable interest. Critical Accounting Policies and Estimates Provisions for Income Taxes. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax con- sequences of events that have been recognized in an entity’s financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Revenue Recognition on Incentive-Based Advisory Contracts. The Company has certain investment advi- sory contracts in which a portion of the fees are based on investment performance achieved in the respective client portfolio in excess of a specified hurdle rate. For management fees based on a formula, there are two methods by which incentive revenue may be recorded. Under “Method 1,” incentive fees are recorded at the end of the contract year. Under “Method 2,” incentive fees are recorded periodically and calculated as the amount that would be due under the formula at any point in time as if the contract was terminated at that date. Manage- ment has chosen the more conservative Method 1, in which performance fees are recorded at the end of the con- tract period provided for by the contract terms. Revenue Recognition when Acting as an Agent vs. Principal. The Funds have selected and contractually engaged certain vendors to fulfill various services to benefit the Funds’ shareholders or to satisfy regulatory require- ments of the Funds. These services include, among others, required fund shareholder mailings, registration fees, legal and audit fees. DHCM, in fulfilling a portion of its role under the administration agreement with the Funds, acts as agent to pay these obligations of the Funds. Each vendor is independently responsible for fulfillment of the services it has been engaged to provide and negotiates fees and terms with the management and board of trustees of the Funds. The fee that the Funds pay to DHCM is reviewed annually by the Funds’ board of trustees and specifically takes into account the contractual expenses that DHCM pays on behalf of the Funds. As a result, DHCM is not involved in the delivery or pricing of these services and bears no risk related to these services. Revenue has been recorded net of these Fund expenses, as it is the appropriate accounting treatment for this agency relationship. Beacon Hill has underwriting agreements with certain clients, including registered mutual funds. Part of Beacon Hill’s role as underwriter is to act as an agent on behalf of its mutual fund clients to receive 12b-1/service fees and commission revenue and facilitate the payment of those fees and commissions to third parties who pro- vide services to the funds and their shareholders. The amount of 12b-1/service fees and commissions are determined by each mutual fund client and Beacon Hill bears no financial risk related to these services. As a result, 12b-1/service fees and commission revenue has been recorded net of the expense payments to third par- ties, as it is the appropriate accounting treatment for this agency relationship. 25 ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk The Company’s revenues and net income are based primarily on the value of AUM. Accordingly, declines in financial market values directly and negatively impact the Company’s investment advisory revenues and net income. The Company invests in Diamond Hill Funds and its private investment funds, which are market risk sensi- tive financial instruments. These investments have inherent market risk in the form of equity price risk; that is, the potential future loss of value that would result from a decline in their fair value. The bond fund (Diamond Hill Strategic Income Fund) is also subject to market risk which may arise from changes in equity prices, credit ratings and interest rates. Market prices fluctuate and the amount realized upon subsequent sale may differ sig- nificantly from the reported market value. The table below summarizes the Company’s market risks as of December 31, 2012, and shows the effects of a hypothetical 10% increase and decrease in equity and bond investments.

Financial Statements and Supplementary Data Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders Diamond Hill Investment Group, Inc.: We have audited the accompanying consolidated balance sheet of Diamond Hill Investment Group, Inc. and subsidiaries (the Company) as of December 31, 2012, and the related consolidated statements of income, shareholders’ equity, and cash flows for the year then ended. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assess- ing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Diamond Hill Investment Group, Inc. and subsidiaries as of December 31, 2012, and the results of their operations and their cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2012, based on cri- teria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Orga- nizations of the Treadway Commission (COSO), and our report dated March 8, 2013 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. /s/ KPMG LLP Columbus, Ohio March 8, 2013 27 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders Diamond Hill Investment Group, Inc.: We have audited Diamond Hill Investment Group, Inc.’s (the Company) internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assess- ment of the effectiveness of internal control over financial reporting, included in the accompanying Manage- ment’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A of the Company’s December 31, 2012 annual report on Form 10-K. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the compa- ny’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect mis- statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that con- trols may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Diamond Hill Investment Group, Inc. and subsidiaries as of December 31, 2012, and the related consolidated statements of operations, shareholders’ equity, and cash flows for the year then ended, and our report dated March 8, 2013 expressed an unqualified opinion on those con- solidated financial statements. /s/ KPMG LLP Columbus, Ohio March 8, 2013 28 Report of Independent Registered Public Accounting Firm To Shareholders and Board of Directors of Diamond Hill Investment Group, Inc.

Notes to Consolidated Financial Statements Note 1 Business and Organization Diamond Hill Investment Group, Inc. (the “Company”) derives its consolidated revenues and net income primarily from investment advisory and fund administration services. The Company has three operating sub- sidiaries. Diamond Hill Capital Management, Inc. (“DHCM”), an Ohio corporation, is a wholly owned subsidiary of the Company and a registered investment adviser. DHCM is the investment adviser to the Diamond Hill Funds (the “Funds”), a series of open-end mutual funds and certain private investment funds (“Private Funds”), and also offers advisory services to institutional and individual investors. Diamond Hill GP (Cayman) Ltd. (“DHGP”), which was organized for the purpose of acting as the general partner of a Cayman Islands exempted limited partnership sponsored by the Company, was dissolved during the third quarter of 2012. DHGP had no operating activity. Beacon Hill Fund Services, Inc. (“BHFS”), an Ohio corporation, is a wholly owned subsidiary of the Com- pany. BHFS provides certain compliance, treasury, and fund administration services to mutual fund companies. BHIL Distributors, Inc. (“BHIL”), an Ohio corporation, is a wholly owned subsidiary of BHFS. BHIL provides underwriting and distribution services to mutual fund companies. BHFS and BHIL collectively operate as Bea- con Hill. Note 2 Significant Accounting Policies The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses for the periods. Actual results could differ from those estimates. Certain prior period amounts and disclosures have been reclassified to conform to the current period financial presentation. Book value per share is computed by dividing total shareholders’ equity by the number of shares issued and out- standing at the end of the measurement period. The following is a summary of the Company’s significant accounting policies: Principles of Consolidation The accompanying consolidated financial statements include the operations of the Company and its sub- sidiaries. All material inter-company transactions and balances have been eliminated in consolidation. Segment Information Management has determined that the Company operates in one business segment, namely providing invest- ment management and administration services to mutual funds, separate accounts, and private investment funds. Therefore, no disclosures relating to operating segments are required in annual or interim financial statements. Cash and Cash Equivalents Cash and cash equivalents include demand deposits and money market mutual funds. Accounts Receivable Accounts receivable are recorded when they are due and are presented on the balance sheet, net of any allow- ance for doubtful accounts. Accounts receivable are written off when they are determined to be uncollectible. Any allowance for doubtful accounts is estimated based on the Company’s historical losses, existing conditions in the industry, and the financial stability of those individuals or entities that owe the receivable. No allowance for doubtful accounts was deemed necessary at December 31, 2012 or December 31, 2011. 34 Valuation of Investment Portfolio Investments held by the Company are valued based upon the definition of Level 1 inputs and Level 2 inputs. Level 1 inputs are defined as fair values which use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are defined as quoted prices in markets that are not considered to be active for identical assets or liabilities, quoted prices in active markets for similar assets or liabilities, and inputs other than quoted prices that are directly observable or indirectly through corroboration with observable market data. The following table summarizes the values of the Company’s investments based upon Level 1 and Level 2 inputs as of December 31, 2012 and December 31, 2011: As of December 31, 2012 2011 Level 1 Inputs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Level 2 investments are all limited partnerships. There were no transfers in or out of the levels. The changes in market values on the investments are recorded in the Consolidated Statements of Income as investment income. Limited Partnership Interests DHCM is the managing member of Diamond Hill General Partner, LLC (the “General Partner”), the general partner of Diamond Hill Investment Partners, L.P. (“DHIP”), Diamond Hill Investment Partners II, L.P. (“DHIP II”), Diamond Hill Research Partners, L.P. (“DHRP”), Diamond Hill Research Partners – International, L.P. (“DHRPI”), and Diamond Hill Valuation-Based Index, L.P. (“DHVBI”) collectively (the “Partnerships”), each a limited partnership whose underlying assets consist of marketable securities. Effective January 3, 2012, Diamond Hill Research Partners, L.P. converted to Diamond Hill Research Opportunities Fund, a series of the Diamond Hill Funds. On July 18, 2012, DHIP II was liquidated. DHCM, in its role as managing member of the General Partner, has the power to direct the Partnerships’ economic activities and the right to receive investment advisory and performance incentive fees that may be sig- nificant to the Partnerships. The Company evaluated these Partnerships to determine whether or not to con- solidate the entities in accordance with FASB ASC 810, Consolidation. Certain of these Partnerships are considered to be variable interest entities (“VIEs”) while others are considered to be voting rights entities (“VREs”) both of which are subject to consolidation consideration. The Company would consolidate VIEs where the Company is considered the primary beneficiary or VREs where the General Partner is considered to control the Partnership. For the Partnerships that were considered VIEs, the Company was not deemed to be the primary beneficiary. For the Partnerships that were considered VREs, it was determined that the DHCM in its role of managing member of the General Partner did not control the Partnerships. Therefore, the investments are accounted for under the equity method rather than being consolidated in the accompanying financial statements. DHCM’s investments in these Partnerships are reported as a component of the Company’s investment port- folio, valued at DHCM’s proportionate interest in the net asset value of the marketable securities held by the Partnerships. Gains and losses attributable to changes in the value of DHCM’s interests in the Partnerships are included in the Company’s reported investment income. The Company’s exposure to loss as a result of its involvement with the Partnerships is limited to the amount of its investments. DHCM is not obligated to provide financial or other support to the Partnerships, other than its investments to date and its contractually provided investment advisory responsibilities, and has not provided such support. The Company has not provided liquidity arrangements, guarantees or other commitments to support the Partnerships’ operations, and the Partnerships’ creditors and interest holders have no recourse to the general credit of the Company. Certain board members, officers and employees of the Company invest in DHIP. These individuals receive no remuneration as a result of their personal investment in the Partnership. The capital of the General Partner is not subject to a management fee or an incentive fee. 35 Furniture and Equipment Furniture and equipment, consisting of computer equipment, furniture, and fixtures, are carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over estimated lives of three to seven years. Deferred Compensation Liability Deferred compensation liability represents compensation that will be paid out upon satisfactory completion of certain performance-based criteria specified in employee award agreements issued pursuant to the 2011 Equity and Cash Incentive Plan. See footnote 5. Revenue Recognition — General The Company earns substantially all of its revenue from investment advisory and fund administration serv- ices. Mutual fund investment advisory and administration fees, generally calculated as a percentage of assets under management, are recorded as revenue as services are performed. Managed account and private investment fund clients provide for monthly or quarterly management fees, in addition to periodic variable incentive fees. Revenue Recognition — Incentive Revenue The Company manages certain client accounts that provide for variable incentive fees. These fees are based on investment results over rolling five-year periods. For variable management fees based on a formula, there are two methods by which incentive revenue may be recorded. Under “Method 1”, incentive fees are recorded at the end of the contract measurement period; under “Method 2”, the incentive fees are recorded periodically and calculated as the amount that would be due under the formula at any point in time as if the contract was terminated at that date. Management has chosen Method 1, in which incentive fees are recorded at the end of the contract measurement period for the specific client in which the incentive fee applies. The table below shows assets under management (“AUM”) subject to incentive fees and the incentive fees, as calculated under each of the above methods: As of December 31, 2012 2011 2010 AUM Contractual Period Ends: Calendar Quarter-End . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

These services include mutual fund administration, transfer agency and other related functions. For performing these services, each fund compensates DHCM a fee, which is calculated using the following annual rates times the average daily net assets of each respective series and share class: Prior to February 29, 2012 After February 29, 2012 Class A and Class C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Funds have selected and contractually engaged certain vendors to fulfill various services to benefit the Funds’ shareholders or to satisfy regulatory requirements of the Funds. These services include, among others, required fund shareholder mailings, federal and state registrations, and legal and audit services. DHCM, in ful- filling a portion of its role under the administration agreement with the Funds, acts as agent to pay these obliga- tions of the Funds. Each vendor is independently responsible for fulfillment of the services it has been engaged to provide and negotiates fees and terms with the management and board of trustees of the Funds. The fee that the Funds pay to DHCM is reviewed annually by the Funds’ board of trustees and specifically takes into account the contractual expenses that DHCM pays on behalf of the Funds. As a result, DHCM is not involved in the delivery or pricing of these services and bears no risk related to these services. Revenue has been recorded net of these Fund related expenses, in accordance with FASB ASC 605-45, Revenue Recognition – Principal Agent Consid- erations. In addition, DHCM finances the upfront commissions which are paid to brokers who sell Class C shares of the Funds. As financer, DHCM advances the commission amount to be paid to the selling broker at the time of sale. These advances are capitalized and amortized over 12 months to correspond with the repayments DHCM receives from the principal underwriter to recoup this commission advancement. Beacon Hill has underwriting and administrative service agreements with certain clients, including regis- tered mutual funds. The fee arrangements vary from client to client based upon services provided and are recorded as revenue under Mutual Fund Administration on the Consolidated Statements of Income. Part of Bea- con Hill’s role as underwriter is to act as an agent on behalf of its mutual fund clients to receive 12b-1/service fees and commission revenue and facilitate the payment of those fees and commissions to third parties who pro- vide services to the funds and their shareholders. The amount of 12b-1/service fees and commissions are determined by each mutual fund client and Beacon Hill bears no financial risk related to these services. As a result, 12b-1/service fees and commission revenue has been recorded net of the expense payments to third par- ties, in accordance with the appropriate accounting treatment for this agency relationship. 37 Mutual fund administration gross and net revenue are summarized below: Year Ended December 31, 2012 2011 2010 Mutual fund administration: Administration revenue, gross . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12b-1/service fees and commission revenue received from fund $13,074,707 $11,617,140 $10,940,041 clients . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6,868,974 7,058,471 8,122,268 12b-1/service fees and commission expense payments to third parties . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Expenses recognized represent actual payments made to the third party firms and are recorded in the period earned based on the terms of the various contracts. Income Taxes The Company accounts for income taxes through an asset and liability approach. Deferred taxes are pro- vided on an asset and liability method, whereby deferred tax assets are recognized for deductible temporary dif- ferences and deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The Company is subject to examination by various federal, state and local jurisdictions for various tax peri- ods. The Company’s income tax positions are based on research and interpretations of the income tax laws and rulings in each of the jurisdictions in which the Company does business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws between those jurisdictions, as well as the inherent uncertainty in estimating the final resolution of complex tax audit matters, the Company’s estimates of income tax liabilities may differ from actual payments or assessments. The Company regularly assesses its position with regard to tax exposures and records liabilities for these uncertain tax positions and related interest and penalties, if any, according to the principles of FASB ASC 740, Income Taxes. As of December 31, 2012, the Company has not recorded any liability for uncertain tax positions. Earnings Per Share Earnings per share (“EPS”) is computed by dividing net income by the weighted average number of com- mon shares outstanding for the period. For the periods presented, the Company does not have dilutive securities outstanding. 38 Note 3 Investment Portfolio As of December 31, 2012, the Company held investments excluding money market funds, included with cash and cash equivalents, worth $16.5 million and an estimated cost basis of $12.4 million.

Authorization of Preferred Shares The Company’s Amended and Restated Articles of Incorporation authorize the issuance of 1,000,000 shares of “blank check” preferred shares with such designations, rights and preferences, as may be determined from time to time by the Company’s Board of Directors. The Board of Directors is authorized, without shareholder approval, to issue preferred stock with dividend, liquidation, conversion, voting, or other rights, which could adversely affect the voting or other rights of the holders of the Common Shares. There were no shares of pre- ferred stock issued or outstanding at December 31, 2012 or December 31, 2011. 39 Note 5 Stock-Based Compensation Equity Incentive Plans 2011 Equity and Cash Incentive Plan At the Company’s annual shareholder meeting on April 26, 2011, shareholders approved the 2011 Equity and Cash Incentive Plan (“2011 Plan”). The 2011 Plan is intended to facilitate the Company’s ability to attract and retain staff, provide additional incentives to employees, directors and consultants, and promote the success of the Company’s business. The 2011 Plan authorizes the issuance of 600,000 Common Shares of the Company in various forms of equity awards. The 2011 Plan also authorizes cash incentive awards. As of December 31, 2012, there were 313,576 Common Shares available for awards under the 2011 Plan. The 2011 Plan provides that the Board of Directors, or a committee appointed by the Board, may grant awards and otherwise administer the 2011 Plan. Restricted stock grants issued under the 2011 Plan, which vest over time, are recorded as deferred compen- sation in the equity section of the balance sheet on the grant date and then recognized as compensation expense based on the grant date price over the vesting period of the respective grant. 2005 Employee and Director Equity Incentive Plan At the Company’s annual shareholder meeting on May 12, 2005, shareholders approved the 2005 Employee and Director Equity Incentive Plan (“2005 Plan”). There are no longer any Common Shares available for future issuance under the 2005 Plan, although outstanding grants under the 2005 Plan remain issued and outstanding. Restricted stock grants issued under the 2005 Plan, which vest over time, are recorded as deferred compensation in the equity section of the balance sheet on the grant date and then recognized as compensation expense based on the grant date price over the vesting period of the respective grant.

Employees may contribute a por- tion of their compensation subject to certain limits based on federal tax laws. The Company makes matching contributions of Common Shares of the Company with a value equal to 200 percent of the first six percent of an employee’s compensation contributed to the plan. Employees become fully vested in the matching contributions after six plan years of employment. The following table summarizes the Company’s expenses attributable to the plan during the years ended December 31, 2012, 2011 and 2010: 2012 $1,044,255 2011 $960,888 40 2010 $897,843 Stock Options and Warrants The Company recognizes all share-based payments to employees and directors, including grants of stock options, as expense in the income statement based on their fair values. The amount of compensation is measured at the fair value of the options when granted, and this cost is expensed over the required service period, which is normally the vesting period of the options. There were no stock options outstanding during the periods presented in these financial statements. There were no warrants outstanding as of December 31, 2012, 2011, and 2010.

Note 7 Income Taxes The Company files a consolidated Federal income tax return. It is the policy of the Company to allocate the consolidated tax provision to subsidiaries as if each subsidiary’s tax liability or benefit were determined on a separate company basis.

Included in 2012 is $1,992,298 which relates to tax benefits not previously claimed by the Com- pany. The Company plans to claim these deductions in future tax returns.

The Company believes it is more likely than not that the results of future operations will gen- erate sufficient taxable income to realize the net deferred tax assets recorded. The Company records a valuation when it is more likely than not that some portion of all of the deferred tax assets will not be realized. As of December 31, 2012, no valuation allowance was deemed necessary. FASB ASC 740, Income Taxes, prescribes a recognition threshold and measurement attribute for the finan- cial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company did not record an accrual for tax related uncertainties or unrecognized tax positions as of December 31, 2012. The Company does not expect a change to the reserve for uncertain tax positions within the next twelve months that would have a material impact on the consolidation financial state- ments. The Company files income tax returns in the federal and all applicable state and local jurisdictions. The Company is subject to federal, state and local examinations by tax authorities for tax years ended December 31, 2009 through 2012.

Additionally, in the normal course of busi- ness, the Company enters into agreements that contain a variety of representations and warranties and which provide general indemnifications. Certain agreements do not contain any limits on the Company’s liability and would involve future claims that may be made against the Company that have not yet occurred. Therefore, it is not possible to estimate the Company’s potential liability under these indemnities. Further, the Company main- tains insurance policies that may provide coverage against certain claims under these indemnities. 43 ITEM 9. Changes In and Disagreements With Accountants on Accounting and Financial Disclosures The Company changed independent accountants in October 2012 from Plante & Moran PLLC to KPMG LLP. Information regarding the change in independent accountants was reported in the Company’s Current Report on Form 8-K filed with the SEC on October 30, 2012. There were no disagreements or any reportable events subject to Item 304 of Regulation S-K requiring disclosure. ITEM 9A. Controls and Procedures Management, including the Chief Executive Officer and the Chief Financial Officer, has conducted an evalu- ation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act of 1934) as of the end of the period covered by this report (the “Evaluation Date”). Based on such evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and to ensure that the information required to be disclosed by the Company in the reports it files or sub- mits under the Exchange Act is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. There have been no changes in the Company’s internal control over financial reporting during the year ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, the Compa- ny’s internal control over financial reporting. Management’s Annual Report on Internal Control Over Financial Reporting Management of Diamond Hill Investment Group, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act. The Company’s internal control over financial reporting is a process designed to provide reason- able assurance regarding the reliability of financial reporting and the preparation of its consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect mis- statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that con- trols may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of the Chief Executive Officer and the Chief Financial Officer, management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2012 based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2012. The Company’s independent registered public accounting firm, KPMG LLP, has audited the Company’s 2012 consolidated financial statements included in this Annual Report on Form 10-K and the Company’s internal control over financial reporting as of December 31, 2012, and has issued its Report of Independent Registered Public Accounting Firm on Consolidated Financial Statements, which is included in this Annual Report on Form 10-K.
