PART I

Item 1. Business

Throughout this Form 10-K, the Company may make forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 relating to such matters as anticipated operating results, prospects 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” 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 markets; a decline in the performance of the Company’s products; changes in interest rates; a general downturn in the economy; 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 SEC.

General

Diamond Hill Investment Group, Inc. (the “Company”), an Ohio corporation organized in 1990, derives its consolidated revenue and net income from investment advisory services provided by its subsidiary Diamond Hill Capital Management, Inc. (“DHCM”). DHCM is a registered investment adviser under the Investment Advisers Act of 1940 providing investment advisory services to individuals and institutional investors through the Diamond Hill sponsored mutual funds, separate accounts, and private investment funds (generally known as “hedge funds”). The Company was first incorporated in April 1990.

During 2004, the Company transitioned the operations and services of its broker-dealer subsidiary, Diamond Hill Securities, Inc. (“DHS”) to third party broker-dealers and to DHCM in an effort to solely focus on investment management activities. During the fourth quarter of 2004, DHS de-registered with the NASD and SEC as a broker-dealer and investment adviser. This transition had no material impact on the Company’s financial statements.

Assets Under Management

As of December 31, 2006, assets under management totaled $3.7 billion, a 142% increase from December 31, 2005. The following tables show assets under management by product and investment objective for the dates indicated:


	Assets Under Management by Product
	As of December 31,
(in millions)	2006		2005		2004

Mutual funds	$	2,518	$	907	$	238

Total	$	3,708	$	1,531	$	524

Investment Advisory Activities

DHCM executes its investment strategies through fundamental research and valuation disciplines. Analysts evaluate a company’s prospects based upon its current business and financial position, future growth opportunities, and management capability and strategy. The intended result is a good estimate of “intrinsic value”. Intrinsic value is the present value of all future cash flows, which we estimate the investment will generate, discounted at a rate that reflects the required return for the investment given the estimated level of risk. In other words, it is the estimated price a minority shareholder should pay in order to achieve a satisfactory or “fair” return on the investment. The estimate of intrinsic value is then compared to the current market price to evaluate whether, in the opinion of DHCM, an attractive investment opportunity exists. A proprietary valuation model, which takes into account projected cash flows for five years including a “terminal value” (the expected stock price in five years), assists in many of these intrinsic value estimations. DHCM applies an intrinsic value philosophy to the analysis of fixed income securities.

DHCM believes that although securities markets are competitive, pricing inefficiencies often exist allowing for attractive investment opportunities. 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 intrinsic value) is a reliable method to achieve above average returns as well as mitigate risk.

Current portfolio strategies managed include Small Cap, Small-Mid Cap, Large Cap, Select, Long-Short, Financial Long-Short, and Strategic Income. These strategies are available on a separately managed basis and/or through a mutual fund. The Small Cap strategy was closed to new investors as of December 31, 2005.

The Company also manages three private investment funds that utilize the Long-Short strategy. These funds are offered on a private placement basis to accredited and qualified investors in the United States and around the world.

Marketing

The Company primarily generates business for all three of its product lines (mutual funds, managed accounts, and private investment funds) through financial intermediaries including independent registered investment advisors, brokers, financial planners, investment consultants and third party marketing firms.

Diamond Hill Funds

The Company’s mutual fund portfolios have, we believe, strong investment performance track records and are highly rated by third party services like Morningstar, Inc. (“Morningstar”) and Lipper Analytical, Inc. (“Lipper”). As of December 31, 2006, 100% of the Diamond Hill Funds (the “Funds”), that are eligible for a rating were rated four or five stars by Morningstar. In addition, all of the Funds with a five year track record were ranked in the top quartile of their respective Lipper categories. As a result, the Company has had success in raising assets by focusing on independent registered investment advisors and independent broker/dealers who conduct their own investment research. During 2006, the Company added resources to mutual fund distribution through wirehouse broker/dealers and 401k platforms. Below is a summary of the assets in the Funds by distribution channel as of December 31, 2006 and 2005:


	Diamond Hill Funds
	Assets by Distribution Channel
	as of December 31,
(in millions)	2006		2005

Independent registered Investment advisors and broker/dealers	$	1,161	$	421
Wirehouse and regional broker/dealers		917		392
Defined contribution (401k)		157		33
Institutions		132		41
Other		40		20

Total	$	2,407	$	907

Separate Accounts and Private Investment Funds

The Company continues to develop institutional relationships for separate account management primarily through consultant relationships, database research screens, and direct marketing. In June 2006, the Company launched two private investment funds. Both are managed in a similar fashion to the Company’s existing private investment partnership. Diamond Hill Offshore Ltd. is domiciled in the Cayman Islands for use by foreign entities and qualified U.S. entities. Diamond Hill Investment Partners II, L.P. is an Ohio limited partnership, similar to the Company’s existing partnership; however, it is designed for institutions and “super-accredited” investors. The Company has also engaged a third party placement firm to assist in raising assets in the private investment funds. To date, efforts by the third party placement firm have been successful. The third party firm earns 20% of all revenue earned from clients it introduced to the Company.

Growth Prospects

As mentioned the Company’s mutual funds, separately managed accounts, and private investment funds, have strong five year investment returns that we believe compare very favorably to competitors. Investment returns have been a key driver in the success the Company has achieved in growing assets under management at a rate in excess of 100% annually in 2006, 2005, 2004 and 2003.

As a result, the Company expects to continue to invest in marketing throughout 2007 in an effort to expand distribution. Such expenditures are expected to include:

•		establishing new selling relationships,

•		adding additional marketing and support staff,

•		attending and sponsoring booths at key industry conferences, and

•		creating additional marketing material for the funds and separately managed accounts.

The cost of these efforts could be significant but, we believe, will be proportional to the increase in revenue during 2007 and future years. There can be no assurance that these efforts will prove successful; however, given the investment results of the Funds and separately managed accounts, we believe the additional resources devoted to marketing are warranted.

Also recognizing that the Company’s primary responsibility is to investors in our Funds and our separate account clients, we will continue to invest in our investment team and close investment strategies to new investors when appropriate. For example, our Small Cap strategy was closed to new investors effective December 31, 2005. In 2006, the company substantially increased its equity investment team adding two portfolio managers, four equity research analysts and trading and technology support. A full year cost for those additions will be reflected in 2007.

We believe 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. We are pleased that in our history as an investment advisory firm we have delivered what we believe are excellent investment returns for our clients. However, we are mindful that if we fail to do so in the future, our business growth will be negatively impacted. There are certain additional business risks that may prevent the Company from achieving the above growth prospects. These risks are detailed in Item 1A.

Competition

Competition in the area of investment management services and mutual funds 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, are better capitalized, offer a broader range of investment products and have more offices, employees and sales representatives. The Company competes primarily on the basis of investment philosophy, performance and customer service.

Corporate Investment Portfolio

The Company holds investment positions in Diamond Hill Funds and its private investment funds.

Regulation

DHCM is registered with the Securities and Exchange Commission (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 disclosure obligations. All Diamond Hill Funds are registered with the SEC under the Investment Company Act of 1940. Each fund is also required to make notice filings with all states where it is offered for sale. Virtually all aspects of the Company’s investment management business are subject to various federal and state laws and regulations. Generally, these laws and regulations are primarily intended to benefit shareholders of the funds and separate account investment clients and generally grant supervisory agencies and bodies broad administrative powers, including the power to limit or restrict the Company from carrying on its investment management business in the event that it fails to comply with such laws and regulations. In such event, possible sanctions which may be imposed include the suspension of individual employees, business limitations on DHCM engaging in the investment management business for specified periods of time, the revocation of DHCM’s registration as an investment adviser, and other censures or fines.

Contractual Relationships with the Diamond Hill Funds

The Company is very dependent on its contractual relationships with the Funds. In the event the advisory or administration agreements with Funds are canceled or not renewed pursuant to the terms thereof, the Company would be materially and adversely affected. 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 Funds will choose to continue their relationships with the Company. The Company generated approximately 54% of its 2006 revenues from its advisory and administrative contracts with Diamond Hill Funds.

Employees

As of December 31, 2006 the Company employed 32 full-time employees and one part-time employee. The Company generally believes that its relationship with its employees is good and does not anticipate any material change in the number of employees.

SEC Filings

This Form 10-K includes financial statements for the years ended December 31, 2006, 2005, and 2004. The Company files Forms 10-K annually with the SEC and files Forms 10-Q after each of the first three fiscal quarters. Prior to this year, the Company was a small business issuer making its annual 10-K filing on Form 10-KSB and its quarterly filings on Form 10-QSB. A copy of the Form 10-K, as filed with the SEC, will be furnished without charge to any shareholder who contacts the Company’s Secretary at 325 John H. McConnell Blvd., Suite 200, Columbus, OH 43215 or 614.255.3333. The Company also makes its SEC filings available, free of charge, on its web site at www.diamond-hill.com.

ITEM 1A: Risk Factors

An investment in the Company’s common shares involves various risks, including those mentioned below and those that are discussed from time-to-time in our 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 decision regarding the Company’s common shares. There may be additional risks of which we are currently unaware, or which we currently consider immaterial. All of these risks could have a material adverse effect on our financial condition, results of operations, and value of our common stock.

Investment Performance.
If we fail to deliver excellent performance for our clients, both in the short and long term, we will likely experience diminished investor interest and potentially a diminished level of AUM.

The Company’s assets under management, which impact revenue, are subject to significant fluctuations.
Substantially all revenue for the Company is calculated as percentages of assets under management or is based on the general performance of the equity securities market. A decline in securities prices or in the sale of investment products or an increase in fund redemptions generally would reduce fee income. Financial market declines or adverse changes in interest rates would generally negatively impact the level of the Company’s assets under management and consequently its revenue and net income. A recession or other economic or political events could also adversely impact the Company’s revenue if it led to a decreased demand for products, a higher redemption rate, or a decline in securities prices.

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 analysts, and management, many of whom have specialized expertise and extensive experience in the 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 and Chief Financial Officer, key employees do not have employment contracts, and generally can terminate their employment at any time. We cannot assure that we will be able to retain or replace key personnel. In order to retain or replace our key personnel, we may be required to increase compensation, which would decrease net income. The loss of key personnel could damage our reputation and make it more difficult to retain and attract new employees and investors. Losses of assets from our client investors would decrease our revenues and net income, possibly materially.

The Company is subject to substantial competition in all aspects of its business.
The Company’s investment products compete against an ever-increasing number of investment products
and services from:

•		asset management firms,

•		mutual fund companies,

•		commercial banks and thrift institutions,

•		insurance companies,

•		hedge funds, and

•		brokerage and investment banking firms.

Many of these financial institutions have substantially greater resources than the Company and may offer a broader range of products or operate in more markets. Some operate in a different regulatory environment which may give them certain competitive advantages in the investment products and portfolio structures that they offer. The Company competes with other providers of investment advisory services primarily based our investment performance. Some institutions have proprietary products and distribution channels that make it more difficult for us to compete with them. If current or potential customers decide to use one of our competitors, we could face a significant decline in market share, assets under management, revenues, and net income. If we are required to lower our fees in order to remain competitive, our net income could be significantly reduced because some of our expenses are fixed, especially over shorter periods of time, and others may not decrease in proportion to the decrease in revenues.

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.
We provide investment advisory and administrative services to the Diamond Hill Funds under various agreements. The board of each Diamond Hill Fund must annually approve the terms of the investment management and administration agreements and can terminate the agreement upon 60-day notice. If a Diamond Hill Fund seeks to lower the fees that we receive or terminate its contract with us, we would experience a decline in fees earned from the Diamond Hill Funds, which could have a material adverse effect on our revenues and net income. The Company derived 54% of its 2006 revenue from investment advisory and administration agreements with Diamond Hill Funds.

The Company’s business is subject to substantial governmental regulation.
The Company’s business is subject to variety of federal securities laws including the Investment Advisors Act of 1940, the Investment Company Act of 1940, the Securities Exchange Act of 1934, Sarbanes-Oxley Act of 2002, and the U.S. Patriot Act of 2001. In addition, the Company is subject to significant regulation and oversight by the SEC and NASD. 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 Company continually monitors legislative, tax, regulatory, accounting, and compliance developments that could impact its business.

We 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: Description of Property

The Company’s current policy is not to invest in real estate or interests in real estate primarily for possible capital gain or primarily for income. We do not invest in real estate mortgages or securities of entities primarily engaged in real estate activities.

ITEM 3: Legal Proceedings

The Company is currently not engaged in any litigation or other legal proceedings.

ITEM 4: Submission of Matters to a Vote of Security Holders

There were no matters submitted during the most recent quarter to a vote of security holders.

PART II

ITEM 5: Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The Company’s common shares trade on the NASDAQ Capital Market under the symbol DHIL. The following table sets forth the high and low sale and closing prices each quarter since during 2006 and 2005:

The following performance graph compares the total shareholder return of an investment in Diamond Hill’s Common Stock to that of the Russell Microcap^TM Index, and to two separate peer group indexes of publicly traded asset management firms for the five-year period ending on December 31, 2006. The graph assumes that the value of the investment in Diamond Hill’s Common Stock and each index was $100 on December 31, 2001. Total return includes reinvestment of all dividends. According to Russell, the Microcap^TM 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 securities. Peer Group returns are weighted by the market capitalization of each firm at the beginning of each measurement period. The historical information set forth below is not necessarily indicative of future performance. Diamond Hill does not make or endorse any predictions as to future stock performance.

Due to the relatively low volume of traded shares, quoted prices cannot be considered indicative of any viable market for such shares. During the years ended December 31, 2006, and 2005, approximately 1,079,800 and 653,700, respectively, of the Company’s Common Shares were traded.

The approximate number of registered holders of record of the Company’s common shares at December 31, 2006 was 250. Many of the shares are held in street nominee name and management believes the number of beneficial holders of the Company’s common shares as of December 31, 2006 were approximately 2,100. The Company has not paid any dividends during the last two fiscal years and has no present intention of paying dividends.

The Company did not repurchase any of its common shares during 2006 or 2005.

ITEM 7: Management’s Discussion and Analysis of Financial Condition and Results of Operation

In this section we discuss and analyze 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 consolidated Financial Statements, Notes to the Consolidated Financial Statements, and Selected Financial Data.

The Company’s revenue is derived primarily from investment advisory and administration fees received from Diamond Hill Funds and investment advisory and performance incentive fees received from separate accounts and private investment funds. Investment advisory and administration fees paid to the Company are based primarily on the value of the investment portfolios managed by the Company and fluctuate with changes in the total value of the assets under management. Such fees are recognized in the period that the Company manages these assets. Performance incentive fees are earned in the amount 20% annually on the amount of client investment performance in excess of a 5% annual return hurdle. Because performance incentive fees are based primarily on the performance of client accounts, they can be volatile from period to period. The Company’s major expense is employee compensation and benefits.

The following is a summary of the firm’s assets under management (“AUM”) for each of the prior three years:


	Assets Under Management by Product
	As of December 31,
(in millions)	2006		2005		2004

Pro-forma net income illustrates the Company’s 2005 earnings adjusted for the impact of federal income taxes. Under GAAP, the Company recorded an income tax benefit of $1.66 million reflecting the likelihood that tax loss carryforwards would be utilized in future years. Therefore, under GAAP, the Company did not incur income tax expense in 2005 despite $1.989 million in net income before tax and, instead, recorded an income tax benefit for the year. Pro forma earnings, which the Company believes are useful for readers of the financial statements to ascertain the underlying profitability of the Company, do not include the tax benefit of $1.66 million but instead reflect income tax expense of $781 thousand assuming the Company paid federal and city income tax on taxable income. The Company does not use the pro-forma net income or pro-forma earnings amounts for any other purpose.

Year ended December 31, 2006 compared with Year Ended December 31, 2005
The Company posted net income of $8,065,133 ($3.63 per diluted share) for the year ended December 31, 2006, compared with pro-forma net income of $1,208,206 ($0.61 per diluted share) for the year ended December 31, 2005. The increase in profitability is primarily attributable to the following factors:

	•		The Company’s investment advisory fee and mutual fund administration fee increase is substantially due an increase in AUM of $2.2 billion during 2006.

	•		Performance incentive fees increased by 172% due to increase AUM and strong investment performance.

	•		Investment income grew by $1.9 million due to a larger investment in the private investment funds and strong investment performance.

Operating expenses increased by 150% in 2006 primarily driven by the following:

	•		Employee compensation expense increased by 163%, or $11.3 million primarily due to higher incentive compensation and an overall staff increase of 52%, primarily on the investment team.

	•		Consistent with continued growth in mutual fund assets under management, mutual fund administration expense increased by 104%, or $860,496.

	•		Consistent with higher investment advisory and performance incentive fees, third party distribution expenses increased by 252%, or $559,385. A large portion of this increase was related to the new third party placement firm hired during 2006 to focus on distribution of the private investment funds.

Year ended December 31, 2005 compared with Year Ended December 31, 2004
The Company posted pro-forma net income of $1,208,206 ($0.61 per diluted share) for the year ended December 31, 2005, compared with a net loss of $176,500 (($0.11) per diluted share) for the year ended December 31, 2004. The increase in profitability is primarily attributable to increased investment advisory and performance incentive fees due to $1 billion in additional AUM. The profitability increase was offset by an increase in incentive compensation.

Revenue

Investment advisory		20,247		6,489		212	%		6,489		2,290		183	%

Total		31,904		10,246		211	%		10,246		2,774		269	%

As a percent of total 2006 revenues, investment advisory fees account for 63%, performance incentive fees account for 25%, and mutual fund administration makes up the remaining 12%.

Investment Advisory Fees. Investment advisory fees are calculated as a percent of average net assets under management at various levels depending on the investment product. The Company’s average advisory fee rate for the year ended December 31, 2006 was 0.76% compared to 0.72% for the year ended December 31, 2005. This increase was mainly due to the increase in assets under management in the long-short products, which have a higher advisory fee. The overall increase in investment advisory fees was primarily due to an increase in AUM of $2.2 billion in 2006 and $1 billion in 2005. The largest increase in 2006 came from the Diamond Hill Long-Short fund which increased $924 million, or 300% over 2005. The largest increase in 2005 came from the Diamond Hill Small Cap fund which increased $315 million, or 445% over 2004.

Performance Incentive Fees. Performance incentive fees are equal to 20% of the performance increase in client accounts after a 5% annual hurdle is achieved. The fees are dependent on both assets under management and absolute investment performance in client accounts and can be volatile from period to period. Incentive fee AUM totaled $374 million at December 31, 2006 compared to $117 million at the end of 2005. Strong investment performance coupled with a 220% increase in incentive fee AUM contributed to the $5 million increase in fees for 2006 compared to 2005. In June 2006, the Company launched two private investment funds, which provide for an incentive fee. In conjunction with the launch of these two funds, a third party placement firm was hired to market the new funds as well as the Company’s existing private investment fund. To date efforts by the third party placement firm have been successful.

Mutual Fund Administration Fees. Mutual fund administration fees are calculated as a percent of average net assets under administration in the Diamond Hill Funds. The Company earns 0.36% on Class A and Class C shares and 0.18% on Class I shares. As assets in the Funds have grown the Company has realized certain economies of scale; and as a result, the Company has lowered its administration fees by approximately 10% in each of the last two years to pass on those economies of scale to fund shareholders. The Company expects to lower its administration fees again effective April 30, 2007. Despite lowering fees by 10% during 2006, fund administration revenues increased by $2.9 million over 2005.

Expenses


(in Thousands)	2006		2005		% Change			2005		2004		% Change

Compensation and related costs		18,148		6,878		164	%		6,878		2,277		202	%

Total		22,136		8,852		150	%		8,852		3,438		157	%

Compensation and Related Costs. Employee compensation and benefits increased by $11.3 million, or 164%, in 2006 and $4.6 million, or 202% in 2005, primarily due to incentive bonuses associated with strong long-term investment performance and a 52% increase in staff, primarily on the investment team.

General and Administrative. The increase in general and administrative expenses of $458 thousand, or 67%, resulted from increased legal and audit fees related to Sarbanes-Oxley, additional investment research costs, and additional rent expense associated with the larger office space the Company moved into during 2006.

Sales and Marketing. Sales and marketing expenses increased by $136 thousand, or 55% during 2006. This increase was primarily due to increased expense related to marketing materials and additional travel expense incurred related to new business attained during the year. Meals and entertainment were flat year over year.

Third Party Distribution. Third party distribution expense represents payments made to third party intermediaries directly related to sales made by those parties of the Company’s investment products. Substantially all of this expense in 2006, 2005, and 2004 is related to new client investments in the Company’s private investment funds. The year over year increases directly correspond to the increase in investment advisory and performance incentive fees earned by the Company.

Mutual Fund Administration. Mutual fund administration expense increased by $860 thousand and $372 thousand in 2006 and 2005, respectively. A large portion of mutual fund administration expense is calculated based on a percent of assets under administration in the Diamond Hill Funds. The year over year increases are consistent with the continued growth in assets under administration.

Liquidity and Capital Resources

The Company’s entire investment portfolio is in readily marketable securities, which provide for cash liquidity, if needed, within three business days. Investments in mutual funds are valued at their current net asset value. Investments in private investment funds are valued based on readily available market quotations. Inflation is expected to have no material impact on the Company’s performance.

As of December 31, 2006, the Company had working capital of approximately $19.1 million compared to $8.4 million at December 31, 2005. Working capital includes cash, securities owned and accounts and notes receivable, net of all liabilities. The Company has no debt and its available working capital is expected to be sufficient to cover current expenses. The Company does not expect any material capital expenditures during 2007; however, capital levels are expected to be impacted by future stock-based option and warrant exercises.

ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk

Our revenues and net income are based primarily on the value of assets under our management. Accordingly, declines in financial market values directly and negatively impact our investment advisory revenues and net income.

The Company invests in Diamond Hill Funds and its private investment funds, which are market risk sensitive 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 the fair value. Each equity fund and its underlying net assets are also subject to market risk, which may arise from changes in equity prices. The bond 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 significantly from the reported market value.

The table below summarizes the Company’s market risks as of December 31, 2006, and shows the effects of a hypothetical 10% increase and decrease in equity and bond fund investments.

Notes to Consolidated Financial Statements

Note 1 Organization

Diamond Hill Investment Group, Inc. (the “Company”) was incorporated as a Florida corporation in April 1990 and in May 2002 merged into an Ohio corporation formed for the purpose of reincorporating in Ohio, where the Company’s principal place of business is located. The Company has two operating subsidiaries.

Diamond Hill Capital Management, Inc. (“DHCM”), an Ohio corporation, is a wholly owned subsidiary of the Company and a registered investment advisor. DHCM is the investment adviser to the Diamond Hill Funds (the “Funds”), a series of open-end mutual funds, private investment funds (the “Private Funds”), and also offers advisory services to institutional and individual investors.

Diamond Hill GP (Cayman) Ltd. (“DHGP”) was incorporated in the Cayman Islands as an exempted company on May 18, 2006 for the purpose of acting as the general partner of a Cayman Islands exempted limited partnership, which partnership will act as a master fund for Diamond Hill Offshore Ltd., a Cayman Islands exempted company; and Diamond Hill Investment Partners II, L.P., an Ohio limited partnership. Diamond Hill GP (Cayman) Ltd. has no operating activity.

Note 2 Significant Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses for the periods. Actual results could differ from those estimates. The following is a summary of the Company’s significant accounting policies:

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year financial presentation.

Principles of Consolidation

The accompanying consolidated financial statements include the operations of the Company, DHCM, and DHGP. All material inter-company transactions and balances have been eliminated in consolidation.

Segment Information

SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information,” establishes disclosure requirements relating to operating segments in annual and interim financial statements. Management has determined that the Company operates in one business segment, namely as an investment adviser managing mutual funds, separate accounts, and private investment funds.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and money market funds.

Accounts Receivable

Accounts receivable are recorded when they are due and are presented in the balance sheet, net of any allowance 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, 2006 and 2005.

Investments in mutual funds are valued at their current net asset value. Investments in Private Funds are valued based on readily available market quotations. The market value adjustments on the investments are recorded in the Consolidated Statement of Income as investment returns.

Limited Partnership Interests

DHCM is the managing member of Diamond Hill General Partner, LLC, the General Partner of Diamond Hill Investment Partners, LP (“DHIP”) and Diamond Hill Investment Partners II, LP (“DHIP II”), each a limited partnership whose underlying assets consist of marketable securities. DHCM’s investment in DHIP and DHIP II is accounted for using the equity method, under which DHCM’s share of the net earnings or losses from the partnership is reflected in income as earned and distributions received are reflected as reductions from the investment. Several board members, officers and employees of the Company invest in DHIP and DHIP II through Diamond Hill General Partner, LLC. These individuals receive no remuneration as a result of their personal investment in DHIP or DHIP II. The capital of Diamond Hill General Partner, LLC is not subject to a management fee or an incentive fee.

Property and Equipment

Property and equipment, consisting of computer equipment, furniture, and fixtures, is carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over estimated lives of three to seven years.

Treasury Stock

Treasury stock purchases are accounted for under the cost method. The subsequent issuances of these shares are accounted for based on their weighted-average cost basis.

Revenue Recognition

The Company earns substantially all of its revenue from investment advisory and fund administration services. Mutual fund investment advisory and administration fees, 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 quarterly or annual performance fees.

EITF Abstract Topic No. D-96, “Accounting for Management Fees Based on a Formula,” identifies two methods by which incentive revenue may be recorded. Under “Method 1,” incentive fees are recorded at the end of the contract 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 the more conservative method (“Method 1”), in which incentive fees are recorded at the end of the contract period for the specific client in which the incentive fee applies. All clients have a contractual period that ends on December 31. Some clients also have a contractual period that ends on each calendar quarter end.

Note 2 Significant Accounting Policies (Continued)

Revenue Recognition – Mutual Fund Administration

DHCM has an administrative, fund accounting and transfer agency services agreement with Diamond Hill Funds, an Ohio business trust, under which DHCM performs certain services for each series of the trust. These services include mutual fund administration, accounting, transfer agency and other related functions. For performing these services, each series of the trust compensates DHCM a fee at an annual rate of 0.36% for Class A and Class C shares and 0.18% for Class I shares times each series’ average daily net assets. In fulfilling its role under this agreement, DHCM has engaged several third-party providers, and the cost for their services is paid by DHCM. A portion of these expenses could, and are typically, paid for directly by the Funds and are classified below as “fund related.” These expenses include, among others, fund custody, registration fees, legal and audit fees. DHCM’s agreement, however, requires that DHCM pay for all fund administration expenses, including those that could be paid directly by the Funds. In addition, DHCM finances the up-front commissions paid to brokers who sell C shares of the Diamond Hill Funds. As financer, DHCM advances the commission to the selling broker at the time of sale. This commission advance is capitalized and amortized off over 12 months to correspond with the payments DHCM receives from the principal underwriter to recoup this commission payment. Mutual fund administration (“admin”) gross and net revenue are summarized below:


	Year Ended December 31,
	2006		2005		2004
Mutual fund admin revenue, gross	$	5,795,110	$	1,736,346	$	619,835

Mutual fund administration revenue, net	$	3,710,141	$	841,527	$	288,960

Income Taxes

Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the various temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.

In June 2006, the FASB issued interpretation No. 48, “Accounting for the Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (FIN 48). FIN 48 clarifies certain aspects of accounting for uncertain tax positions, including issues related to the recognition and measurement of those tax positions. The provisions of FIN 48 are effective for fiscal years beginning after December 15, 2006. Management is currently evaluating the potential impact of the adoption of this interpretation.

Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution of EPS that could occur if options, warrants, and restricted stock units to issue common stock were exercised.

Note 3 Investment Portfolio

As of December 31, 2006, the Company held investments worth $19.1 million and a cost basis of $16.0 million. The following table summarizes the market value of these investments over the last two fiscal years:

Note 4 Capital Stock

Common Shares

The Company has only one class of securities, Common Shares.

Authorization of Preferred Shares

The Company’s 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 empowered, 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 preferred stock issued or outstanding at December 31, 2006.

Note 5 Stock-Based Compensation

Equity Incentive Plans

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”). The 2005 Plan is intended to facilitate the Company’s ability to attract and retain staff, provide additional incentive to employees, directors and consultants, and to promote the success of the Company’s business. The Plan authorizes the issuance of Common Shares of the Company in various forms of stock or option grants. As of December 31, 2006 shares available for issuance under the Plan are 412,197. The Plan provides that the Board of Directors, or a committee appointed by the Board, may grant awards and otherwise administer the Plan.

1993 Non-qualified and Incentive Stock Option Plan

The Company adopted a Non-Qualified and Incentive Stock Option Plan in 1993 that authorized the grant of options to purchase an aggregate of 500,000 shares of the Company’s Common Stock. The Plan provides that the Board of Directors, or a committee appointed by the Board, may grant options and otherwise administer the Option Plan. This Plan expired by its terms in November 2003. Options outstanding under this Plan are not affected by the Plan’s expiration.

Equity Compensation Grants

On May 13, 2004 the Company’s shareholders approved terms and conditions of certain equity compensation grants to three key employees. Under the approved terms a total of 75,000 shares of restricted stock and restricted stock units were issued to the key employees on May 31, 2004. The restricted stock and restricted stock units are restricted from sale and do not vest until May 31, 2009.

401(k) Plan

The Company sponsors a 401(k) plan whereby all employees participate in the plan. Employees may contribute a portion 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. For the years ended December 31, 2006, 2005, and 2004, expense attributable to the plan were $327,090, $238,073 and $134,478, respectively.

Note 5 Stock-Based Compensation (Continued)

Effective October 1, 2005, the Company adopted SFAS No. 123(R), Accounting for Stock-Based Compensation (“SFAS 123R”). SFAS 123R requires all share-based payments to employees and directors, including grants of stock options, to be recognized 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. SFAS 123R applies to the Company for options granted or modified after October 1, 2005. SFAS 123R also requires compensation cost to be recorded for prior option grants that vest after the date of adoption.

Prior to the adoption of SFAS 123R, the Company applied Accounting Principles Board Opinion No. 25 (“APB 25”) and related Interpretations in accounting for stock options and warrants issued to employees and directors. Under APB 25, only certain pro forma disclosures of fair value were required. Had compensation cost for all of the Company’s stock-based awards been determined in accordance with FAS 123R, the Company’s net income and earnings per share would have been reduced to the pro forma amounts indicated below:


	Year Ended December 31,
	2006			2005			2004
Net income (loss), as reported	$	8,065,133		$	3,650,766		$	(176,500	)

Stock-based employee compensation expense included in reported net income, net of related tax effects		27,597			523,505			—
Deduct:
Total stock-based employee compensation expense determined under fair value based methods for all awards net of related tax effects		(27,597	)		(559,139	)		(103,091	)


Pro forma net income (loss)	$	8,065,133		$	3,615,132		$	(279,591	)

Earnings (loss) per share:
Basic — as reported	$	4.51		$	2.21		$	(0.11	)
Basic — pro forma	$	4.51		$	2.18		$	(0.18	)
Diluted — as reported	$	3.63		$	1.83		$	(0.11	)
Diluted — pro forma	$	3.63		$	1.81		$	(0.18	)

The fair value of options granted in 2005 was $8.84. No options were granted in 2006 or 2004. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with following weighted-average assumptions:


Dividend yield:		0.0	%
Expected volatility:		28	%
Expected life:	5 years
Risk-free interest rate:		3.50	%

Note 6 Operating Leases

The Company leases approximately 14,187 square feet of office space at 325 John H. McConnell Blvd, Suite 200, Columbus, Ohio 43215 under an operating lease agreement which terminates on July 31, 2013. Total lease and operating expenses for year ended December 31, 2006, 2005, and 2004 were $206,917, $139,250, and $120,000, respectively. The future minimum lease payments under the operating lease are as follows:


2007	2008		2009		2010		2011		2012		2013
$216,777	$	223,870	$	230,964	$	238,057	$	245,151	$	254,018	$	129,669

In addition to the above rent, the Company will also be responsible for normal operating expenses of the property. Such operating expenses were approximately $8.75 per square foot in 2006, are expected to be $9.04 in 2007 and may increase by no more than 5% annually thereafter.

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. As part of the consolidated group, subsidiaries transfer to the Company their current Federal tax liability or assets.


	2006		2005			2004
Current city income tax provision (benefit)	$	158,090	$	—		$	—
Deferred federal income tax provision (benefit)		4,071,965		(1,661,675	)		—

Provision (benefit) for income taxes	$	4,230,055	$	(1,661,675	)	$	—

A reconciliation of income tax expense at the statutory federal rate to the Company’s income tax expense is as follows:


	2006			2005			2004
Income tax computed at statutory rate	$	4,180,364		$	676,291		$	(60,010	)

Income tax expense (benefit)	$	4,230,055		$	(1,661,675	)	$	—

Deferred tax assets and liabilities consist of the following at December 31, 2006 and 2005:


	2006			2005
Deferred tax benefit of NOL Carryforward	$	248,686		$	2,627,282
Stock-based compensation	$	111,207		$	111,207
Unrealized (gains) losses		(2,264,114	)		(964,277	)
Other assets and liabilities		5,115			(4,080	)

Net deferred tax assets (liabilities)	$	(1,899,106	)	$	1,770,132

For the years ended December 31, 2006 and 2005, the Company received federal tax benefits from the exercise of stock-based compensation of $402,727 and $108,457 respectively, which resulted in an increase to equity.

As of December 31, 2006, the Company and its subsidiaries had net operating loss (NOL) carry forwards for tax purposes of approximately $731,000. These NOL’s will expire from 2016 to 2024. Any future changes in control may limit the availability of NOL carryforwards.

Note 8 Earnings Per Share

The following table sets for the computation for basic and diluted earnings (loss) per share (EPS):


	Year ended December 31,
	2006		2005		2004
Basic and Diluted net income (loss)	$	8,065,133	$	3,650,766	$	(176,500	)
Weighted average number of outstanding shares
Basic		1,787,390		1,654,935		1,566,385
Diluted		2,219,580		1,996,176		1,566,385
Earnings (loss) per share
Basic	$	4.51	$	2.21	$	(0.11	)

Diluted	$	3.63	$	1.83	$	(0.11	)

The diluted EPS calculation excludes the effect of stock options when their exercise prices exceed the average market price for the period. For the years ended December 31, 2006 and 2005, stock options and warrants for 30,202 were excluded from diluted EPS. Due to the net loss in 2004, diluted shares in 2004 exclude the effect of un-exercised options and warrants because the effect of their inclusion would be anti-dilutive.

Note 9 Commitments and Contingencies

The Company indemnifies its directors and certain of its officers and employees for certain liabilities that might arise from their performance of their duties to the Company. Additionally, in the normal course of business, 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 maintains insurance policies that may provide coverage against certain claims under these indemnities.

Note 10 Subsequent Event – 2007 Tax Deduction

On January 3, 2007, February 16, 2007, and February 20, 2007 Roderick H. Dillon, Jr., the Company’s Chief Executive Officer, exercised Options and Warrants to purchase 216,500 shares of the Company’s common stock. As a result of the exercises, the Company will receive a 2007 tax deduction in the amount of $18,273,950.

ITEM 9: Changes In and Disagreements With Accountants or Accounting and Financial Disclosures - None

ITEM 9A: Controls and Procedures

Management, including the Chief Executive Officer and the Chief Financial Officer, has conducted an evaluation of the effectiveness of disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(e) as of the end of the period covered by this annual report. Based on the evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that as of the end of the period covered by this annual report, the disclosure controls and procedures are effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Securities and Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time period specified by the Securities and Exchange Commission’s rules and forms. There were no significant changes in the Company’s internal controls which materially affect, or are reasonable likely to materially affect, the Company’s internal controls over financial reporting.

Management’s report on our internal control over financial reporting and the related attestation report of Plante & Moran PLLC follow.

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 Securities Exchange Act of 1934, as amended. The 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 its consolidated financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

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

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, 2006 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, 2006.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006 has been audited by Plante & Moran, PLLC, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting
Firm on Internal Control Over Financial Reporting

The Shareholders and Board of Directors of
Diamond Hill Investment Group, Inc:

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control over Financial Reporting, that Diamond Hill Investment Group, Inc. maintained effective internal control over financial reporting as of December 31, 2006, 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 assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of 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, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control — Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company as of December 31, 2006 and 2005, and the related consolidated statements of income, changes in shareholders’ equity, and cash flows for the years then ended, of the Company and our report dated March 6, 2007 expressed an unqualified opinion thereon.
