Notes to Consolidated Financial Statements (unaudited)

Note 1 Business and Organization

Diamond Hill Investment Group, Inc. (the “Company”), an Ohio corporation, derives its consolidated revenues and net income from investment advisory and fund administration services provided by its wholly-owned subsidiary, Diamond Hill Capital Management, Inc., an Ohio corporation (“DHCM”).

DHCM is a registered investment adviser, and is the investment adviser and administrator for the Diamond Hill Funds (the "Funds"), a series of open-end mutual funds. DHCM also provides investment advisory services to Diamond Hill Micro Cap Fund, LP (“DHMF”), a private fund, as well as separately managed accounts, other pooled investment vehicles, and model delivery programs.

Note 2 Significant Accounting Policies

Basis of Presentation

The accompanying unaudited, condensed, and consolidated financial statements for Diamond Hill Investment Group, Inc. and its subsidiaries (referred to in these notes to the condensed consolidated financial statements as "the Company," "management," "we," "us," and "our") as of March 31, 2022 and December 31, 2021, and for the three-month periods ended March 31, 2022 and 2021, have been prepared in accordance with United States generally accepted accounting principles ("GAAP"), the instructions to Form 10-Q, and Article 10 of Securities and Exchange Commission (the "SEC") Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of the financial condition and results of operations as of the dates, and for the interim periods, presented, have been included. These unaudited, condensed, and consolidated financial statements and footnotes should be read in conjunction with the audited consolidated financial statements of the Company included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the "2021 Form 10-K"), as filed with the SEC.

Operating results for the three-month period ended March 31, 2022, are not necessarily indicative of the results the Company may expect for the full fiscal year ending December 31, 2022.

For further information regarding the risks to the Company's business, refer to the consolidated financial statements and notes thereto included in the 2021 Form 10-K and in “Part II – Item 1A. – Risk Factors” of this Quarterly Report on Form 10-Q.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions related to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenue and expense during the period. Actual results could differ from those estimates.

Reclassification

Certain amounts and disclosures for prior periods may have been reclassified to conform to the current period's financial presentation.

Principles of Consolidation

The accompanying consolidated financial statements include the operations of the Company and its controlled subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

The Company holds certain investments in the Funds and DHMF, for general corporate investment purposes, to provide seed capital for newly formed strategies or to add capital to existing strategies. The Funds are organized in a series fund structure in which there are multiple mutual funds within one Trust. The Trust is an open-end investment company registered under the Investment Advisers Act of 1940, as amended (the "1940 Act"). Each individual Fund represents a separate share class of a legal entity organized under the Trust. DHMF is organized as a Delaware limited partnership and is exempt from registration under the 1940 Act.

7

The Company performs its consolidation analysis at the individual Fund level and has concluded that the Funds are voting rights entities (“VREs”) because the structure of the Funds is such that the shareholders are deemed to have the power through voting rights to direct the activities that most significantly impact each Fund’s economic performance. To the extent material, these Funds are consolidated if Company ownership, directly or indirectly, represents a majority interest (greater than 50%). The Company records redeemable noncontrolling interests in consolidated investments for which the Company's ownership is less than 100%. As of March 31, 2022, the Company has consolidated the Diamond Hill International Fund and the Diamond Hill Large Cap Concentrated Fund (together, the "Consolidated Funds").

DHCM is the investment manager of DHMF and is the managing member of Diamond Hill Fund GP, LLC (the “General Partner”), which is the general partner of DHMF. DHCM is wholly owned by, and consolidated with, the Company. Further, DHCM, through its control of the General Partner, has the power to direct DHMF’s economic activities and the right to receive investment advisory fees that may be significant from DHMF. DHMF commenced operations on June 1, 2021, and its underlying assets consist primarily of marketable securities.

The Company concluded DHMF was a variable interest entity (“VIE”) given that: (i) DHCM has disproportionately less voting interest than economic interest, and (ii) DHMF's limited partners have full power to remove the General Partner (which is controlled by the Company) due to the existence of substantive kick-out rights. In addition, substantially all of DHMF's activities are conducted on behalf of the General Partner, which has disproportionately few voting rights. The Company concluded it is not the primary beneficiary of DHMF as it lacks the power to control DHMF, since DHMF's limited partners have single-party kick-out rights and can unilaterally remove the General Partner without cause. DHCM’s investments in DHMF are reported as a component of the Company’s investment portfolio and valued at DHCM’s respective share of DHMF's net income or loss.

Gains and losses attributable to changes in the value of DHCM’s interests in DHMF are included in the Company’s reported investment income. The Company’s exposure to loss as a result of its involvement with DHMF is limited to the amount of its investment. DHCM is not obligated to provide, and has not provided, financial or other support to DHMF, except for its investments to date and its contractually provided investment advisory responsibilities. The Company has not provided liquidity arrangements, guarantees, or other commitments to support DHMF’s operations, and DHMF’s creditors and interest holders have no recourse to the general credit of the Company.

Redeemable Noncontrolling Interest

Redeemable noncontrolling interest represents third-party interests in the Consolidated Funds. This interest is redeemable at the option of the investors, and therefore, is not treated as permanent equity. Redeemable noncontrolling interest is recorded at redemption value, which approximates the fair value each reporting period.

Segment Information

Management has determined that the Company operates in a single business segment, which is providing investment advisory and related services to clients through pooled investment vehicles, including the Funds, DHMF, separately managed accounts, and model delivery programs. Therefore, the Company does not present disclosures relating to operating segments in annual or interim financial statements.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and money market mutual funds held by DHCM.

Accounts Receivable

The Company records accounts receivable when they are due and presents them on 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 the individual or entity that owes the receivable. No allowance for doubtful accounts was deemed necessary at either March 31, 2022, or December 31, 2021. Accounts receivable from the Funds were $11.6 million as of March 31, 2022, and $11.8 million as of December 31, 2021.

Investments

Management determines the appropriate classification of its investments at the time of purchase and re-evaluates its determination for each reporting period.

8

Company sponsored investments, where the Company has neither control nor the ability to exercise significant influence, as well as securities held in the Consolidated Funds are measured at fair value based on quoted market prices. Unrealized gains and losses are recorded as investment income (loss) in the Company's consolidated statements of income.

Investments classified as equity method investments represent investments in which the Company owns between 20-50% of the outstanding voting interests in the entity or where it is determined that the Company is able to exercise significant influence but not control over the investments. When using the equity method, the Company recognizes its respective share of the investee's net income or loss for the period, which is recorded as investment income in the Company's consolidated statements of income.

Property and Equipment

Property and equipment, consisting of leasehold improvements, right-of-use lease assets, computer equipment, capitalized software, furniture, and fixtures are carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated lives of the assets.

Implementation costs incurred to develop or obtain internal-use software, including hosting arrangements, are capitalized and expensed on a straight-line basis over either the estimated useful life of the respective software or the term of the hosting arrangement.

Property and equipment is tested for impairment when there is an indication that the carrying amount of an asset may not be recoverable. When an asset is determined to not be recoverable, the impairment loss is measured based on the excess, if any, of the carrying value of the asset over its fair value.

Revenue Recognition – General

The Company recognizes revenue when it satisfies performance obligations under the terms of a contract with a client. The Company earns substantially all of its revenue from DHCM investment advisory and fund administration contracts. Investment advisory and administration fees, generally calculated as a percentage of assets under management ("AUM"), are recorded as revenue as services are performed. In addition to fixed fees based on a percentage of AUM, certain client accounts also provide periodic performance-based fees.

Revenue earned during the three months ended March 31, 2022 and 2021 under contracts with clients include:

	Three Months Ended March 31, 2022
	Investment advisory		Mutual fund administration, net		Total revenue
Proprietary funds	$	27,254,928	$	2,977,500	$	30,232,428

Revenue Recognition – Investment Advisory Fees

DHCM's investment advisory contracts with clients have a single performance obligation because the contracted services are not separately identifiable from other obligations in the contracts, and therefore, are not distinct. All obligations to provide investment advisory services are satisfied over time by DHCM, and the Company recognizes revenue through DHCM as time passes.

The fees DHCM receives for its services under its investment advisory contracts are based on AUM, which changes based on the value of securities held under each investment advisory contract. These fees are thereby constrained and represent variable consideration, and they are excluded from revenue until the AUM on which DHCM's client is billed is no longer subject to market fluctuations.

DHCM also provides its strategy model portfolios and related services to sponsors of model delivery programs. For its services, DHCM is paid a model delivery fee by the program sponsor at a pre-determined rate based on the amount of assets in the program. Model delivery program revenues were $1.7 million and $0.9 million for the three months ended March 31, 2022 and 2021, respectively.

Revenue Recognition – Performance-Based Fees

DHCM manages certain client accounts that pay performance-based fees. These fees are calculated based on client investment results over rolling five-year periods. The Company records performance-based fees when it is probable that a significant reversal of the revenue will not occur. The Company did not record any performance-based fees during the three-month periods ended March 31, 2022 or March 31, 2021. The table below shows AUM subject to performance-based fees and the amount of performance-based fees that would be recognized based upon investment results as of March 31, 2022:

	As of March 31, 2022
	AUM subject to performance-based fees		Unearned performance-based fees
Contractual Measurement Period Ending:
Quarter Ending September 30, 2022	$	505,870,628	$	1,091,899
Total	$	505,870,628	$	1,091,899

The contractual end dates highlight the time remaining until the performance-based fees are scheduled to be earned. The amount of performance-based fees that would be recognized based upon investments results as of March 31, 2022 will increase or decrease based on future client investment results through the end of the contractual period.

Revenue Recognition – Mutual Fund Administration

DHCM has an administrative and transfer agency services agreement with the Funds under which DHCM performs certain services for each Fund. These services include performance obligations, such as mutual fund administration, fund accounting, transfer agency, and other related functions. These services are performed concurrently under DHCM's agreement with the Funds, all performance obligations to provide these administrative services are satisfied over time, and the Company recognizes the related revenue as time progresses. Each Fund pays DHCM a fee for performing these services, which is calculated using an annual rate multiplied by the average daily net assets of each respective Fund share class. These fees are thereby constrained and represent variable consideration, and they are excluded from revenue until the AUM on which DHCM bills the Funds is no longer subject to market fluctuations.

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 shareholder mailings, federal and state registrations, and legal and audit services. In fulfilling a portion of its role under the administrative and transfer agency services agreement with the Funds, DHCM acts as agent and pays for these services on behalf of the Funds. Each vendor is independently responsible for fulfillment of the services it has been engaged to provide and negotiates its fees and terms directly with the management and board of trustees of the Funds. Each year, the Funds' board of trustees reviews the fee that each Fund pays to DHCM, and specifically considers 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.

Mutual fund administration gross and net revenue are summarized below:

	Three Months Ended   March 31,
	2022		2021
Mutual fund administration:
Administration revenue, gross	$	6,940,172	$	6,960,008
Fund related expense	(3,962,672)		(4,514,678)
Mutual fund administration revenue, net	$	2,977,500	$	2,445,330

Income Taxes

The Company accounts for current and deferred income taxes through an asset and liability approach. Deferred tax assets are recognized for deductible temporary differences, 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 federal and applicable state and local jurisdictions for various tax periods. 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 it does business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws among those jurisdictions, and 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 positions 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 Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 740, Income Taxes. The Company records interest and penalties within income tax expense on the income statement. See Note 8.

Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period, which includes unvested restricted shares. See Note 9.

Recently Adopted Accounting Guidance

The Company did not adopt any new accounting guidance during the three months ended March 31, 2022, that had a material effect on its financial position or results of operations.

Newly Issued But Not Yet Adopted Accounting Guidance

The Company has considered all newly issued accounting guidance that is applicable to its operations and the preparation of its

consolidated statements, including guidance it has not yet adopted. The Company does not believe that any such guidance had, or will have, a material effect on its financial position or results of operations.

Note 4 Fair Value Measurements

The Company determines the fair value of its cash equivalents and certain investments using the following broad levels listed below:

Level 1 - Unadjusted quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-driven valuations in which all significant inputs are observable.

Level 3 - Valuations derived from techniques in which significant inputs are unobservable. The Company does not value any investments using Level 3 inputs.

These levels are not necessarily indicative of the risk or liquidity associated with investments.

The following table summarizes investments that are recognized in the Company's consolidated balance sheet using fair value measurements (excluding investments classified as equity method investments) determined based upon the differing levels as of March 31, 2022:

	Level 1		Level 2		Level 3	Total
Cash equivalents	$	55,274,878	—		—	$	55,274,878
Fair value investments:
Securities held in Consolidated Funds(a)	42,429,301		$	33,191,829	—	75,621,130
Company-sponsored investments	$	73,186,055	—		—	$	73,186,055

(a) Of the securities held in the Consolidated Funds as of March 31, 2022, the Company directly held $53.2 million and noncontrolling shareholders held $22.4 million.

Changes to fair values of the investments are recorded in the Company’s consolidated statements of income as investment income (loss) net.

Note 5 Line of Credit

The Company has a committed Line of Credit Agreement (the "Credit Agreement") with a commercial bank that matures on December 23, 2022, which permits the Company to borrow up to $25.0 million. Borrowings under the Credit Agreement bear interest at a rate equal to the Secured Overnight Financing Rate plus 1.10%. The Company pays a commitment fee on the unused portion of the facility, accruing at a rate per annum of 0.10%.

The proceeds of the Credit Agreement may be used by the Company and its subsidiaries for ongoing working capital needs, to seed new and existing investment strategies, and for other general corporate purposes. The Credit Agreement contains customary representations, warranties, and covenants.

The Company did not borrow under the Credit Agreement for the period ended March 31, 2022, and no borrowings were outstanding as of March 31, 2022.

Note 6 Compensation Plans

Share-Based Payment Transactions

The Company issues restricted stock grants under the 2014 Equity and Cash Incentive Plan (the "2014 Plan"). Restricted stock grants represent common shares issued and outstanding upon grant subject to vesting restrictions. The Company has historically issued stock grants that cliff vest after five years to all new employees upon hire and as additional grants to key employees on a periodic basis. While the Company currently plans to continue to issue five-year cliff vest grants to new employees, beginning in 2021, the Company also began making new long-term incentive awards to existing employees in the form of three-year graded vesting stock grants.

Restricted stock grants issued under the 2014 Plan are valued based upon the fair market value of the common shares on the applicable grant date. The restricted stock grants are recorded as deferred compensation in the equity section of the balance sheet on the grant date and then recognized as compensation expense on a straight-line basis over the vesting period of the respective grant. The Company's policy is to adjust compensation expense for forfeitures as they occur.

13

The following table represents a roll-forward of outstanding restricted stock and related activity for the three months ended March 31, 2022:

	Shares	Weighted-Average Grant Date Price per Share
Outstanding restricted stock as of December 31, 2021	201,170	$	165.61
Grants issued	66,190	176.78
Grants vested	(2,337)	147.66
Grants forfeited	(1,321)	185.09
Total outstanding restricted stock as of March 31, 2022	263,702	$	168.47

As of March 31, 2022, 111,389 common shares remained available for grants under the 2014 Plan.

Total deferred equity compensation related to unvested restricted stock was $24.5 million as of March 31, 2022. The recognition of compensation expense related to deferred compensation over the remaining vesting periods is as follows:

Nine Months   Remaining In
2022		2023		2024		2025		2026		Thereafter		Total
$	8,154,950	$	9,186,423	$	5,734,659	$	1,311,147	$	87,481	$	1,638	$	24,476,298

Employee Stock Purchase Plan

Under the Diamond Hill Investment Group, Inc. Employee Stock Purchase Plan (the "ESPP"), eligible employees may purchase shares of the Company's common stock at 85% of the fair market value on the last day of each offering period. Each offering period is approximately three months, which coincides with the Company's fiscal quarters. During the three-month period ended March 31, 2022, ESPP participants purchased 2,335 shares of common stock for $0.4 million, and the Company recorded $0.1 million of share-based payment expense related to these purchases. During the three-month period ended March 31, 2021, ESPP participants purchased 2,583 shares of common stock for $0.3 million, and the Company recorded $0.1 million of share based payment expense related to these purchases.

Stock Grant Transactions

The following table represents common shares issued as part of the Company's incentive compensation program during the three-month periods ended March 31, 2022, and 2021:

	Shares Issued	Grant Date Value
March 31, 2022	2,743	$	487,870
March 31, 2021	3,681	$	529,806

401(k) Plan

The Company sponsors a 401(k) plan in which all employees are eligible to participate. Employees may contribute a portion of their compensation subject to certain limits based on federal tax laws. The Company matches employee contributions equal to 250.0% of the first 6.0% of an employee’s compensation contributed to the plan. The Company settles the 401(k) plan matching contributions in cash or common shares of the Company based on the election of the employees.

Deferred Compensation Plans

The Company offers two deferred compensation plans: the Diamond Hill Fixed Term Deferred Compensation Plan and the Diamond Hill Variable Term Deferred Compensation Plan (together, the “Plans”). Under the Plans, participants may elect to voluntarily defer, for a minimum of five years, certain incentive compensation that the Company then contributes into the Plans. Participants are responsible for designating investment options for the assets they contribute, and the distribution paid to each participant reflects any gains or losses on the assets realized in connection with the Plans. Assets held in the Plans are included in the Company’s investment portfolio, and the associated obligation to participants is included in deferred compensation liability. Deferred compensation liability was $34.0 million and $37.3 million as of March 31, 2022 and December 31, 2021, respectively.

14

Note 7 Operating Lease

The Company currently leases office space of approximately 37,829 square feet at a single location.

As of March 31, 2022, the carrying value of this right-of-use asset, which is included in property and equipment, was approximately $1.5 million net of deferred rent on the consolidated balance sheets. As of March 31, 2022, the carrying value of the lease liability was approximately $1.8 million, which is included in accounts payable and accrued expenses on the consolidated balance sheets.

The following table summarizes the total lease and operating expenses for the three-month periods ended March 31, 2022 and 2021:

	March 31, 2022		March 31, 2021
Three Months Ended	$	204,953	$	209,042

The approximate future minimum lease payments under the operating lease are as follows:

Future Minimum Lease Payments
Nine Months   Remaining In
2022		2023		2024		2025		2026		Total
$	468,134	$	624,179	$	624,179	$	156,045	$	—	$	1,872,537

Note 8 Income Taxes

The Company has determined its interim tax provision projecting an estimated annual effective tax rate.

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

	Three Months Ended   March 31,
	2022		2021
Statutory U.S. federal income tax rate	21.0	%	21.0	%
State and local income taxes, net of federal benefit	4.6	%	4.4	%
Internal revenue code section 162 limitations	1.3	%	1.1	%
Other	(0.9)	%	—	%
Unconsolidated effective income tax rate	26.0	%	26.5	%
Impact attributable to redeemable noncontrolling interest(a)	1.9	%	(0.8)	%
Effective income tax rate	27.9	%	25.7	%

(a) The provision for income taxes includes the impact of the operations of the Consolidated Funds, which are not subject to federal income taxes. Accordingly, a portion of the Company’s earnings are not subject to corporate tax levels.

Absent the impact attributable to redeemable noncontrolling interest, the estimated unconsolidated effective income tax rate would have been 26.0%. The Company's actual effective tax rate for fiscal year ending December 31, 2022 could be materially different from the projected rate as of March 31, 2022.

The net temporary differences incurred to date will reverse in future periods as the Company generates taxable earnings. The Company believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax assets recorded. The Company records a valuation allowance when it is more likely than not that some or all of the deferred tax assets will not be realized. As of March 31, 2022 and December 31, 2021, no valuation allowance was deemed necessary.

15

FASB ASC 740, Income Taxes, prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return, and also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.  The Company recognizes tax benefits related to positions taken, or expected to be taken, on its tax returns, only if the positions are more likely than not sustainable. Once this threshold has been met, the Company’s measurement of its expected tax benefits is recognized in its financial statements. The Company did not record an accrual for tax-related uncertainties or unrecognized tax positions as of March 31, 2022 or December 31, 2021.

The Company did not recognize any interest and penalties during the three months ended March 31, 2022.

Note 9 Earnings Per Share

The Company’s common shares outstanding consist of all shares issued and outstanding, including unvested restricted shares. Basic and diluted EPS are calculated under the two-class method. The following table sets forth the computation for basic and diluted EPS:

	Three Months Ended   March 31,
	2022		2021
Net Income	$	8,275,016	$	14,262,613
Less: Net loss (income) attributable to redeemable noncontrolling interest	854,936		(554,102)
Net income attributable to common shareholders	$	9,129,952	$	13,708,511
Weighted average number of outstanding shares - Basic	3,185,930		3,156,768
Weighted average number of outstanding shares - Diluted	3,185,930		3,156,768
Earnings per share attributable to common shareholders
Basic	$	2.87	$	4.34
Diluted	$	2.87	$	4.34

Note 10 Commitments and Contingencies

The Company indemnifies its directors, officers, and certain employees for certain liabilities that may arise from the performance of their duties to the Company. From time to time, the Company may be involved in legal matters relating to claims arising in the ordinary course of business. There are currently no such matters pending that the Company believes could have a material adverse effect on its consolidated financial statements.

Additionally, in the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and that provide general indemnification obligations. Certain agreements do not contain any limits on the Company’s liability and could 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 of these liabilities.

Note 11 Sale of Diamond Hill's High Yield-Focused Investment Advisory Contracts

DHCM entered into an asset purchase agreement dated February 2, 2021 (the “Purchase Agreement”) with Brandywine Global Investment Management, LLC (“Brandywine Global”), a specialist investment manager of Franklin Resources, Inc. The transaction closed on July 30, 2021 ("Closing Date"), at which time Brandywine Global acquired the investment advisory contracts of DHCM’s two high yield-focused mutual funds - the Corporate Credit Fund and the High Yield Fund (the “High Yield-Focused Advisory Contracts”).

DHCM determined the gain on this transaction in accordance with ASC 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets. DHCM received an initial cash payment at closing of $9.0 million, which was included in gain on sale of high yield-focused advisory contracts in the Consolidated Statements of Income during the third quarter of 2021.

DHCM may receive two additional payments of up to $13.0 million in the aggregate based on the net revenue of the Corporate Credit Fund and the High Yield Fund on July 30, 2022. The Company has not recorded any additional gain for the two potential

16

additional payments because this variable consideration is constrained based on movements in the financial markets and the net shareholder flows of the Corporate Credit Fund and the High Yield Fund. Therefore, there can be no reasonable assurance that all or any of these additional payments will be received by DHCM.

17

Note 12 Subsequent Events

On April 26, 2022, the Company's board of directors ("Board") approved a quarterly cash dividend of $1.50 per share, payable on June 17, 2022, to shareholders of record as of June 2, 2022. This dividend is expected to reduce shareholders' equity by approximately $4.8 million.

General

The Company derives consolidated revenue and net income from investment advisory and fund administration services provided by DHCM. DHCM is a registered investment adviser under the Investment Advisers Act of 1940, as amended. DHCM sponsors, distributes, and provides investment advisory and related services to clients through pooled investment vehicles, including the Funds, DHMF, separately managed accounts, and model delivery programs.

DHCM is committed to generating excellent, long-term investment outcomes and building enduring client partnerships. By committing to shared investment principles, including valuation-disciplined active portfolio management, fundamental bottom-up research, and a long-term business owner mindset, DHCM has created a suite of investment strategies designed for long-term strategic allocations from institutionally-oriented investors. DHCM’s core values of curiosity, ownership, trust, and respect create an environment where investment professionals focus on results and all teammates focus on the overall client experience. The combination of these investment principles and core values creates an aligned boutique model ensuring our associates have a vested interest in our clients’ success. This alignment with clients is emphasized through: (i) personal investment by Diamond Hill employees in the strategies managed, (ii) a fee philosophy focused on a fair sharing of the economics among clients, employees, and shareholders, (iii) a strict adherence to capacity discipline ensuring the ability to add value for existing clients, and (iv) compensation driven by the value created for clients.

The Company's primary objective is to fulfill its fiduciary duty to its clients. The Company believes this focus on generating excellent, long-term investment outcomes and building enduring client partnerships will enable it to grow its intrinsic value to achieve a compelling, long-term return for its shareholders.

Assets Under Management

The Company derives revenue primarily from DHCM's investment advisory and administration fees. Investment advisory and administration fees paid to DHCM are generally based on the value of the investment portfolios it manages and fluctuate with changes in the total value of its AUM. The Company, through DHCM, recognizes revenue when it satisfies its performance obligations under the terms of a contract with a client.

19

The Company's revenues are highly dependent on both the value and composition of AUM. The following is a summary of the Company's AUM by product and investment objective, as well as a roll-forward of the change in AUM, for the three months ended March 31, 2022 and 2021:

Fixed Income	44		488
	$	237	$	1,744

AUM decreased $0.7 billion during the three months ended March 31, 2022, due primarily to depreciation in the financial markets, which was partially offset by net inflows into our strategies during the period. With the exception of Small Cap and Mid Cap, all of our other equity strategies had positive flows during the three months ended March 31, 2022. Fixed income net inflows during the three months ended March 31, 2022, were primarily into our Core Bond strategy.

Model Delivery Programs - Assets Under Advisement

DHCM provides strategy-specific model portfolios to sponsors of model delivery programs. DHCM does not have discretionary investment authority over individual client accounts in model delivery programs, and therefore these assets are not included in the Company's AUM. Rather, we refer to these model delivery assets as assets under advisement ("AUA"). DHCM is paid for its services by the program sponsor at a pre-determined rate based on the amount of AUA in the program. Model delivery AUA was $2.1 billion as of March 31, 2022,  $2.1 billion as of December 31, 2021, and $1.4 billion as of March 31, 2021.

Summary Discussion of Consolidated Results of Operations - Three Months Ended March 31, 2022, compared with Three Months Ended March 31, 2021

Revenue for the three months ended March 31, 2022, increased $3.2 million compared to the three months ended March 31, 2021, primarily due to a 8% increase in average AUM. This increase was partially offset by a decrease in the average advisory fee rate from 0.53% to 0.52% quarter-over-quarter.

Operating profit margin was 45% for the three months ended March 31, 2022, and 35% for the three months ended March 31, 2021. Operating profit margin, as adjusted, was 42% for the three months ended March 31, 2022, and 43% for the same period in 2021. Operating profit margin, as adjusted, excludes deferred compensation expense (benefit) from operating income because it is offset by an equal amount in investment income below net operating income on the income statement and thus has no effect on net income attributable to the Company. The Company believes this non-GAAP measure helps the reader to understand its core operating results and increases comparability period-to-period. See "Use of Supplemental Data as Non-GAAP Performance Measure" section within this Quarterly Report on Form 10-Q.

The Company expects that its operating margin will fluctuate from period to period based on various factors, including revenues, investment results in the strategies we manage, employee performance, staffing levels, and gains and losses on investments held in deferred compensation plans.

The Company had $7.6 million in investment losses due to market depreciation for the three months ended March 31, 2022, compared to $5.7 million in investment income due to market appreciation for the three months ended March 31, 2021.

Income tax expense decreased $1.7 million for the three months ended March 31, 2022, compared to the same period in 2021. The decrease in income tax expense was primarily due to the decrease in the Company's income before taxes as a result of the investment losses incurred during the period.

The increase in the effective tax rate from 25.7% to 27.9% period-over-period, is primarily due to the impact attributable to redeemable noncontrolling interest. The provision for income taxes includes the impact of the operations of the Consolidated Funds, which are not subject to federal income taxes. Accordingly, a portion of the Company’s earnings are not subject to corporate tax levels. Absent the impact attributable to redeemable noncontrolling interest, the estimated unconsolidated effective income tax rate would have been 26.0%

The Company generated net income attributable to common shareholders of $9.1 million ($2.87 per diluted share) for the three months ended March 31, 2022, compared with net income attributable to common shareholders of $13.7 million ($4.34 per diluted share) for the three months ended March 31, 2021. The decrease in net income period-over-period was primarily due to the impact of investment losses in the current period versus investment income in the prior period.

Revenue

	Three Months Ended   March 31,
(in thousands, except percentages)	2022		2021		% Change
Investment advisory	$	39,279	$	36,569	7	%
Mutual fund administration, net	2,977		2,445		22	%
Total	$	42,256	$	39,014	8	%

Investment Advisory Fees. Investment advisory fees for the three months ended March 31, 2022, increased $2.7 million, or 7%, compared to the three months ended March 31, 2021. Investment advisory fees are calculated as a percentage of the market value of client accounts at contractual fee rates, which vary by investment product. The increase in investment advisory fees was primarily due to an increase in average AUM of 8%. The increase was partially offset by a decrease in the average advisory fee rate from 0.53% to 0.52% period-over-period. The decrease in average advisory fee rate was driven by an increase in the mix of assets held in lower fee rate strategies during the three months ended March 31, 2022, compared to the same period in 2021.

Mutual Fund Administration Fees. Mutual fund administration fees for the three months ended March 31, 2022, increased $0.5 million, or 22%, compared to the three months ended March 31, 2021. Mutual fund administration fees include administration fees received from the Funds, which are calculated as a percentage of the Funds' average AUM. The Fund's average AUM increased approximately 2% from the three months ended March 31, 2021, to the three months ended March 31, 2022. The increase in net revenue was due to a reduction in administration fees paid on behalf of the Funds, which was primarily due to the sale of the High Yield-Focused Advisory Contracts and closure of the related funds in the third quarter of 2021.

Expenses

	Three Months Ended   March 31,
(in thousands, except percentages)	2022		2021		% Change
Compensation and related costs, excluding deferred compensation expense (benefit)	$	18,647	$	16,815	11	%

Total	$	23,183	$	25,482	(9)	%

Compensation and Related Costs, Excluding Deferred Compensation Expense (Benefit). Employee compensation and benefits for the three months ended March 31, 2022, increased by $1.8 million compared to the three months ended March 31, 2021. This increase was due to increases in accrued incentive compensation of $1.0 million and in restricted stock expense of $1.0 million, which were partially offset by a decrease in salary and related benefits of $0.2 million. Incentive compensation expense can fluctuate significantly period-over-period as the Company evaluates investment performance, individual performance, Company performance, and other factors.

Deferred Compensation Expense (Benefit). Deferred compensation benefit was $1.2 million for the three months ended March 31, 2022, compared to an expense of $3.1 million for the three months ended March 31, 2021, primarily due to market depreciation on our deferred compensation plan investments period over period.

The gain (loss) on deferred compensation plan investments increases (decreases) deferred compensation expense (benefit) and is included in operating income. Deferred compensation expense (benefit) is offset by an equal amount in investment income below net operating income on the consolidated statements of income, and thus, has no impact on net income attributable to the Company.

General and Administrative. General and administrative expense for the three months ended March 31, 2022, increased by $0.4 million, or 13%, compared to the three months ended March 31, 2021. This increase was primarily due to a increases of $0.2 million in depreciation expense related to our customer relationship management software, $0.1 million in other software expense, and $0.1 million in corporate insurance.

23

Sales and Marketing. Sales and marketing expense for the three months ended March 31, 2022, decreased by $0.2 million, or 8%, compared to the three months ended March 31, 2021. The decrease was primarily due to decreased payments made to third-party intermediaries related to the sale of our Funds on their platforms.

Mutual Fund Administration. Mutual fund administration expenses for the three months ended March 31, 2022, decreased by $0.1 million, or 7%, compared to the three months ended March 31, 2021. Mutual fund administration expenses consist of both variable and fixed expenses. The decrease was primarily due to a decrease in various administrative expenses from the sale of the High Yield-Focused Advisory Contracts and closure of the related funds in the third quarter of 2021.

Liquidity and Capital Resources

Sources of Liquidity

The Company's current financial condition is liquid, with a significant amount of its assets comprised of cash and cash equivalents, investments, accounts receivable, and other current assets. The Company's main source of liquidity is cash flows from operating activities, which are generated from investment advisory and mutual fund administration fees. Cash and cash equivalents, investments held directly by DHCM, accounts receivable, and other current assets represented $188.3 million and $214.7 million of total assets as of March 31, 2022, and December 31, 2021, respectively. The Company believes that these sources of liquidity, as well as its continuing cash flows from operating activities, will be sufficient to meet its current and future operating needs.

Uses of Liquidity

The Company anticipates that its main uses of cash will be for operating expenses and seed capital to fund new and existing investment strategies. The Board and management regularly review various factors to determine whether the Company has capital in excess of that required for its business, and the appropriate uses of any such excess capital including share repurchases and dividends.

Share Repurchases

The Company repurchased 50,104 of its common shares during the three months ended March 31, 2022, for a total of $9.3 million. As of March 31, 2022, $44.8 million remains available for repurchases under the Company's current share repurchase program.

Dividends

Subject to Board approval and compliance with applicable law, the Company expects to pay a regular quarterly dividend of $1.50 per share. In addition to the regular quarterly dividends, the Board will decide whether to approve and pay a special dividend in the fourth quarter of each fiscal year. Although the Company currently expects to pay regular quarterly dividends, depending on various circumstances and the Board's judgment, the Company may not pay such dividends as described. A summary of cash dividends paid during the three months ended March 31, 2022 is presented below:

Dividend	Declaration Date	Date Paid	Dividend Amount (in millions)
First quarter - $1.50 per share	February 25, 2022	March 18, 2022	$	4.8

On April 26, 2022, the Board approved a regular quarterly dividend for the second quarter of 2022 of $1.50 per share. The regular dividend will be paid on June 17, 2022, to shareholders of record as of June 2, 2022. This dividend is expected to reduce shareholders' equity by approximately $4.8 million.

24

Working Capital

As of March 31, 2022, the Company had working capital of approximately $166.2 million, compared to $168.5 million as of December 31, 2021. Working capital includes cash and cash equivalents, accounts receivable, investments, and other current assets of DHCM, net of accounts payable and accrued expenses, accrued incentive compensation, deferred compensation and other current liabilities of DHCM.

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 compensation), and timing differences in the cash settlement of operating assets and liabilities. The Company expects that cash flows provided by operating activities will continue to serve as its primary source of working capital in the near future.

For the three months ended March 31, 2022, net cash used in operating activities totaled $13.7 million. Cash outflows from operating activities were primarily driven by a $27.3 million decrease in the incentive compensation accrual due to the annual incentive compensation payment made in the first quarter of 2022, net change in securities held by the Consolidated Funds of $5.1 million, and the cash impact of timing differences in the settlement of other assets and liabilities of $0.3 million. These outflows were partially offset by net income of $8.3 million, and the add backs of net investment losses of $8.0 million, share-based compensation of $2.3 million, and depreciation of $0.4 million. Absent the cash used in operations by the Consolidated Funds, cash flows used for operations were $9.9 million.

For the three months ended March 31, 2021, net cash used in operating activities totaled $15.7 million. Cash outflows from operating activities were primarily driven by a $19.6 million decrease in the incentive compensation accrual due to the annual incentive compensation payment made in the first quarter of 2021, net change in securities held by the Consolidated Funds of $11.5 million, and the cash impact of timing differences in the settlement of assets and liabilities of $0.6 million. These outflows were partially offset by net income of $14.3 million, and the add backs of share-based compensation of $1.5 million and depreciation of $0.2 million. Absent the cash used in operations by the Consolidated Funds, cash flows used for operations were $5.5 million.

Cash Flows from Investing Activities

The Company’s cash flows from investing activities consist primarily of capital expenditures and purchases and redemptions in our investment portfolio.

Cash flows provided by investing activities totaled $1.8 million for the three months ended March 31, 2022. Cash flows provided by investing activities were primarily driven by proceeds from the sale of Company sponsored investments totaling $3.5 million, which were partially offset by purchases of Company sponsored investments of $1.7 million.

25

Cash flows provided by investing activities totaled $1.6 million for the three months ended March 31, 2021. Cash flows provided by investing activities were primarily driven by proceeds from the sale of Company sponsored investments totaling $3.9 million, which were partially offset by purchases of Company sponsored investments of $1.9 million and property and equipment purchases (primarily capitalized software) of $0.4 million.

Cash Flows from Financing Activities

The Company’s cash flows from financing activities consist primarily of the repurchase of its common stock, shares withheld related to employee tax withholding, dividends paid on its common stock, proceeds received under the ESPP, and distributions to, or contributions from, redeemable noncontrolling interest holders.

For the three months ended March 31, 2022, net cash used in financing activities totaled $9.9 million, consisting of cash outlfows for repurchases of the Company’s common stock of $9.3 million and the payment of quarterly dividends totaling $4.8 million. These cash outflows were partially offset by net subscriptions received in the Consolidated Funds from redeemable noncontrolling interest holders of $3.8 million and proceeds received under the ESPP of $0.4 million.

For the three months ended March 31, 2021, net cash used in financing activities totaled $4.2 million, consisting of cash outflows for the payment of quarterly dividends totaling $3.1 million, repurchases of the Company’s common stock of $1.9 million, and the value of shares withheld related to employee tax withholding of $0.3 million. These cash outflows were partially offset by net subscriptions received in the Consolidated Funds from redeemable noncontrolling interest holders of $0.7 million, and proceeds received under our ESPP of $0.3 million.

Supplemental Consolidated Cash Flow Statement

The Company's consolidated balance sheets reflect the investments and other assets and liabilities of the Consolidated Funds, as well as redeemable noncontrolling interest for the portion of the Consolidated Funds that are held by third-party investors. Although the Company can redeem its net interest in the Consolidated Funds at any time, the Company cannot directly access or sell the assets held by the Consolidated Funds to obtain cash for general operations. Additionally, the assets of the Consolidated Funds are not available to our general creditors.

The following table summarizes the condensed cash flows for the three months ended March 31, 2022, that are attributable to the Company and to the Consolidated Funds, and the related eliminations required in preparing the consolidated statements.

Use of Supplemental Data as Non-GAAP Performance Measure

As supplemental information, the Company is providing performance measures that are based on methodologies other than GAAP (“non-GAAP”). The Company believes that the non-GAAP measures below are useful measures of its core business activities, are important metrics in estimating the value of an asset management business, and may enable more appropriate comparisons to its peers. These non-GAAP measures should not be used as a substitute for financial measures calculated in accordance with GAAP and may be calculated differently by other companies. The following schedule reconciles GAAP measures to non-GAAP measures for the three months ended March 31, 2022 and 2021, respectively.

	Three Months Ended   March 31,
(in thousands, except percentages and per share data)	2022			2021
Total revenue	$	42,256		$	39,014
Net operating income, GAAP basis	$	19,073		$	13,532
Non-GAAP adjustment:
Gains (losses) on deferred compensation plan investments, net(1)	(1,179)			3,103
Net operating income, as adjusted, non-GAAP basis(2)	17,894			16,635
Non-GAAP adjustment:

Net operating income, as adjusted, after tax, non-GAAP basis(4)	$	13,244		$	12,233
Net operating income, as adjusted after tax per diluted share, non-GAAP basis(5)	$	4.16		$	3.87

Operating profit margin, GAAP basis	45		%	35		%
Operating profit margin, as adjusted, non-GAAP basis(6)	42		%	43		%

(1) Gains (losses) on deferred compensation plan investments, net: The gain (loss) on deferred compensation plan investments, which increases (decreases) deferred compensation expense included in operating income, is removed from operating income in the calculation because it is offset by an equal amount in investment income (loss) below net operating income on the income statement, and thus has no impact on net income attributable to the Company.

(2) Net operating income, as adjusted: This non-GAAP measure represents the Company’s net operating income adjusted to exclude the impact on compensation expense of gains and losses on investments in the deferred compensation plan.

(3) Tax provision on net operating income, as adjusted: This non-GAAP measure represents the tax provision, excluding the impact of investment related activity, and is calculated by applying the unconsolidated effective tax rate to net operating income, as adjusted.

(4) Net operating income, as adjusted, after tax: This non-GAAP measure deducts from the net operating income, as adjusted, the tax provision on net operating income, as adjusted.

(5) Net operating income, as adjusted after tax per diluted share: This non-GAAP measure was calculated by dividing the net operating income, as adjusted after tax, by diluted weighted average shares outstanding.

(6) Operating profit margin, as adjusted: This non-GAAP measure was calculated by dividing the net operating income, as adjusted, by total revenue.

27

Off-Balance Sheet Arrangements

The Company has no off-balance sheet arrangements. The Company does not have any obligation under a guarantee contract, a retained or contingent interest in assets, or any 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.

There were no changes in the Company’s internal controls over financial reporting during the quarter ended March 31, 2022, that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting. The Company continues to monitor and assess the impact, if any, that the COVID-19 pandemic and the related economic impacts could have on the design and operating effectiveness of our internal controls.

(a)On February 27, 2020, the Board approved the 2020 Repurchase Program, authorizing management to repurchase up to $50.0 million of our common shares in the open market and in private transactions in accordance with applicable securities laws. The 2020 Repurchase Program expired in February 2022. On February 25, 2022, the Board approved the 2022 Repurchase Program, authorizing management to repurchase up to $50.0 million of Company common shares in the open market and in private transactions in accordance with applicable securities laws. The 2022 Repurchase Program will expire in February 2024, or upon the earlier completion of all authorized purchases under such program.

The Company has entered into a Rule 10b5-1 repurchase plan. This plan is intended to qualify for the safe harbor under Rule 10b5-1 of the Exchange Act.  A Rule 10b5-1 plan allows a company to purchase its stock at times when it would not ordinarily be in the market because of its trading policies or the possession of material nonpublic information. Because repurchases under the 10b5-1 plan are subject to specified parameters and certain price, timing, and volume restraints specified in the plan, there is no guarantee as to the exact number of shares that will be repurchased or that there will be any repurchases at all pursuant to the plan. Purchases may be made in the open market or through privately negotiated transactions. Purchases in the open market will be made in compliance with Rule 10b-18 under the Exchange Act.

Through March 31, 2022, the Company has repurchased 27,307 shares of the Company's common stock under the 2022 Repurchase Program at a total cost of $5.2 million.

Commitments and Contingencies

Commitments and Contingencies

The Company indemnifies its directors, officers, and certain employees for certain liabilities that may arise from the performance of their duties to the Company. From time to time, the Company may be involved in legal matters relating to claims arising in the ordinary course of business. There are currently no such matters pending that the Company believes could have a material adverse effect on its consolidated financial statements.

Additionally, in the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and that provide general indemnification obligations. Certain agreements do not contain any limits on the Company’s liability and could 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 of these liabilities.

Basis of Presentation

The accompanying unaudited, condensed, and consolidated financial statements for Diamond Hill Investment Group, Inc. and its subsidiaries (referred to in these notes to the condensed consolidated financial statements as "the Company," "management," "we," "us," and "our") as of March 31, 2022 and December 31, 2021, and for the three-month periods ended March 31, 2022 and 2021, have been prepared in accordance with United States generally accepted accounting principles ("GAAP"), the instructions to Form 10-Q, and Article 10 of Securities and Exchange Commission (the "SEC") Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of the financial condition and results of operations as of the dates, and for the interim periods, presented, have been included. These unaudited, condensed, and consolidated financial statements and footnotes should be read in conjunction with the audited consolidated financial statements of the Company included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the "2021 Form 10-K"), as filed with the SEC.

Operating results for the three-month period ended March 31, 2022, are not necessarily indicative of the results the Company may expect for the full fiscal year ending December 31, 2022.

For further information regarding the risks to the Company's business, refer to the consolidated financial statements and notes thereto included in the 2021 Form 10-K and in “Part II – Item 1A. – Risk Factors” of this Quarterly Report on Form 10-Q.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions related to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenue and expense during the period. Actual results could differ from those estimates.

Reclassification

Certain amounts and disclosures for prior periods may have been reclassified to conform to the current period's financial presentation.

Principles of Consolidation

The accompanying consolidated financial statements include the operations of the Company and its controlled subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

The Company holds certain investments in the Funds and DHMF, for general corporate investment purposes, to provide seed capital for newly formed strategies or to add capital to existing strategies. The Funds are organized in a series fund structure in which there are multiple mutual funds within one Trust. The Trust is an open-end investment company registered under the Investment Advisers Act of 1940, as amended (the "1940 Act"). Each individual Fund represents a separate share class of a legal entity organized under the Trust. DHMF is organized as a Delaware limited partnership and is exempt from registration under the 1940 Act.

The Company performs its consolidation analysis at the individual Fund level and has concluded that the Funds are voting rights entities (“VREs”) because the structure of the Funds is such that the shareholders are deemed to have the power through voting rights to direct the activities that most significantly impact each Fund’s economic performance. To the extent material, these Funds are consolidated if Company ownership, directly or indirectly, represents a majority interest (greater than 50%). The Company records redeemable noncontrolling interests in consolidated investments for which the Company's ownership is less than 100%. As of March 31, 2022, the Company has consolidated the Diamond Hill International Fund and the Diamond Hill Large Cap Concentrated Fund (together, the "Consolidated Funds").

DHCM is the investment manager of DHMF and is the managing member of Diamond Hill Fund GP, LLC (the “General Partner”), which is the general partner of DHMF. DHCM is wholly owned by, and consolidated with, the Company. Further, DHCM, through its control of the General Partner, has the power to direct DHMF’s economic activities and the right to receive investment advisory fees that may be significant from DHMF. DHMF commenced operations on June 1, 2021, and its underlying assets consist primarily of marketable securities.

The Company concluded DHMF was a variable interest entity (“VIE”) given that: (i) DHCM has disproportionately less voting interest than economic interest, and (ii) DHMF's limited partners have full power to remove the General Partner (which is controlled by the Company) due to the existence of substantive kick-out rights. In addition, substantially all of DHMF's activities are conducted on behalf of the General Partner, which has disproportionately few voting rights. The Company concluded it is not the primary beneficiary of DHMF as it lacks the power to control DHMF, since DHMF's limited partners have single-party kick-out rights and can unilaterally remove the General Partner without cause. DHCM’s investments in DHMF are reported as a component of the Company’s investment portfolio and valued at DHCM’s respective share of DHMF's net income or loss.

Gains and losses attributable to changes in the value of DHCM’s interests in DHMF are included in the Company’s reported investment income. The Company’s exposure to loss as a result of its involvement with DHMF is limited to the amount of its investment. DHCM is not obligated to provide, and has not provided, financial or other support to DHMF, except for its investments to date and its contractually provided investment advisory responsibilities. The Company has not provided liquidity arrangements, guarantees, or other commitments to support DHMF’s operations, and DHMF’s creditors and interest holders have no recourse to the general credit of the Company.

Redeemable Noncontrolling Interest

Redeemable noncontrolling interest represents third-party interests in the Consolidated Funds. This interest is redeemable at the option of the investors, and therefore, is not treated as permanent equity. Redeemable noncontrolling interest is recorded at redemption value, which approximates the fair value each reporting period.

Segment Information

Management has determined that the Company operates in a single business segment, which is providing investment advisory and related services to clients through pooled investment vehicles, including the Funds, DHMF, separately managed accounts, and model delivery programs. Therefore, the Company does not present disclosures relating to operating segments in annual or interim financial statements.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and money market mutual funds held by DHCM.

Accounts Receivable

The Company records accounts receivable when they are due and presents them on 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 the individual or entity that owes the receivable. No allowance for doubtful accounts was deemed necessary at either March 31, 2022, or December 31, 2021. Accounts receivable from the Funds were $11.6 million as of March 31, 2022, and $11.8 million as of December 31, 2021.

Investments

Management determines the appropriate classification of its investments at the time of purchase and re-evaluates its determination for each reporting period.

Company sponsored investments, where the Company has neither control nor the ability to exercise significant influence, as well as securities held in the Consolidated Funds are measured at fair value based on quoted market prices. Unrealized gains and losses are recorded as investment income (loss) in the Company's consolidated statements of income.

Investments classified as equity method investments represent investments in which the Company owns between 20-50% of the outstanding voting interests in the entity or where it is determined that the Company is able to exercise significant influence but not control over the investments. When using the equity method, the Company recognizes its respective share of the investee's net income or loss for the period, which is recorded as investment income in the Company's consolidated statements of income.

Property and Equipment

Property and equipment, consisting of leasehold improvements, right-of-use lease assets, computer equipment, capitalized software, furniture, and fixtures are carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated lives of the assets.

Implementation costs incurred to develop or obtain internal-use software, including hosting arrangements, are capitalized and expensed on a straight-line basis over either the estimated useful life of the respective software or the term of the hosting arrangement.

Property and equipment is tested for impairment when there is an indication that the carrying amount of an asset may not be recoverable. When an asset is determined to not be recoverable, the impairment loss is measured based on the excess, if any, of the carrying value of the asset over its fair value.

Revenue Recognition – General

The Company recognizes revenue when it satisfies performance obligations under the terms of a contract with a client. The Company earns substantially all of its revenue from DHCM investment advisory and fund administration contracts. Investment advisory and administration fees, generally calculated as a percentage of assets under management ("AUM"), are recorded as revenue as services are performed. In addition to fixed fees based on a percentage of AUM, certain client accounts also provide periodic performance-based fees.

Revenue earned during the three months ended March 31, 2022 and 2021 under contracts with clients include:

	Three Months Ended March 31, 2022
	Investment advisory		Mutual fund administration, net		Total revenue
Proprietary funds	$	27,254,928	$	2,977,500	$	30,232,428

Model delivery	906,723		—		906,723
	$	36,569,103	$	2,445,330	$	39,014,433

Revenue Recognition – Investment Advisory Fees

DHCM's investment advisory contracts with clients have a single performance obligation because the contracted services are not separately identifiable from other obligations in the contracts, and therefore, are not distinct. All obligations to provide investment advisory services are satisfied over time by DHCM, and the Company recognizes revenue through DHCM as time passes.

The fees DHCM receives for its services under its investment advisory contracts are based on AUM, which changes based on the value of securities held under each investment advisory contract. These fees are thereby constrained and represent variable consideration, and they are excluded from revenue until the AUM on which DHCM's client is billed is no longer subject to market fluctuations.

DHCM also provides its strategy model portfolios and related services to sponsors of model delivery programs. For its services, DHCM is paid a model delivery fee by the program sponsor at a pre-determined rate based on the amount of assets in the program. Model delivery program revenues were $1.7 million and $0.9 million for the three months ended March 31, 2022 and 2021, respectively.

Revenue Recognition – Performance-Based Fees

DHCM manages certain client accounts that pay performance-based fees. These fees are calculated based on client investment results over rolling five-year periods. The Company records performance-based fees when it is probable that a significant reversal of the revenue will not occur. The Company did not record any performance-based fees during the three-month periods ended March 31, 2022 or March 31, 2021. The table below shows AUM subject to performance-based fees and the amount of performance-based fees that would be recognized based upon investment results as of March 31, 2022:

	As of March 31, 2022
	AUM subject to performance-based fees		Unearned performance-based fees
Contractual Measurement Period Ending:
Quarter Ending September 30, 2022	$	505,870,628	$	1,091,899
Total	$	505,870,628	$	1,091,899

The contractual end dates highlight the time remaining until the performance-based fees are scheduled to be earned. The amount of performance-based fees that would be recognized based upon investments results as of March 31, 2022 will increase or decrease based on future client investment results through the end of the contractual period.

Revenue Recognition – Mutual Fund Administration

DHCM has an administrative and transfer agency services agreement with the Funds under which DHCM performs certain services for each Fund. These services include performance obligations, such as mutual fund administration, fund accounting, transfer agency, and other related functions. These services are performed concurrently under DHCM's agreement with the Funds, all performance obligations to provide these administrative services are satisfied over time, and the Company recognizes the related revenue as time progresses. Each Fund pays DHCM a fee for performing these services, which is calculated using an annual rate multiplied by the average daily net assets of each respective Fund share class. These fees are thereby constrained and represent variable consideration, and they are excluded from revenue until the AUM on which DHCM bills the Funds is no longer subject to market fluctuations.

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 shareholder mailings, federal and state registrations, and legal and audit services. In fulfilling a portion of its role under the administrative and transfer agency services agreement with the Funds, DHCM acts as agent and pays for these services on behalf of the Funds. Each vendor is independently responsible for fulfillment of the services it has been engaged to provide and negotiates its fees and terms directly with the management and board of trustees of the Funds. Each year, the Funds' board of trustees reviews the fee that each Fund pays to DHCM, and specifically considers 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.

Mutual fund administration gross and net revenue are summarized below:

	Three Months Ended   March 31,
	2022		2021
Mutual fund administration:
Administration revenue, gross	$	6,940,172	$	6,960,008
Fund related expense	(3,962,672)		(4,514,678)
Mutual fund administration revenue, net	$	2,977,500	$	2,445,330

Income Taxes

The Company accounts for current and deferred income taxes through an asset and liability approach. Deferred tax assets are recognized for deductible temporary differences, 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 federal and applicable state and local jurisdictions for various tax periods. 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 it does business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws among those jurisdictions, and 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 positions 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 Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 740, Income Taxes. The Company records interest and penalties within income tax expense on the income statement. See Note 8.

Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period, which includes unvested restricted shares. See Note 9.

Recently Adopted Accounting Guidance

The Company did not adopt any new accounting guidance during the three months ended March 31, 2022, that had a material effect on its financial position or results of operations.

Newly Issued But Not Yet Adopted Accounting Guidance

The Company has considered all newly issued accounting guidance that is applicable to its operations and the preparation of its

consolidated statements, including guidance it has not yet adopted. The Company does not believe that any such guidance had, or will have, a material effect on its financial position or results of operations.

Fair Value Measurements

Fair Value Measurements

The Company determines the fair value of its cash equivalents and certain investments using the following broad levels listed below:

Level 1 - Unadjusted quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-driven valuations in which all significant inputs are observable.

Level 3 - Valuations derived from techniques in which significant inputs are unobservable. The Company does not value any investments using Level 3 inputs.

These levels are not necessarily indicative of the risk or liquidity associated with investments.

The following table summarizes investments that are recognized in the Company's consolidated balance sheet using fair value measurements (excluding investments classified as equity method investments) determined based upon the differing levels as of March 31, 2022:

Compensation Plans

Compensation Plans

Share-Based Payment Transactions

The Company issues restricted stock grants under the 2014 Equity and Cash Incentive Plan (the "2014 Plan"). Restricted stock grants represent common shares issued and outstanding upon grant subject to vesting restrictions. The Company has historically issued stock grants that cliff vest after five years to all new employees upon hire and as additional grants to key employees on a periodic basis. While the Company currently plans to continue to issue five-year cliff vest grants to new employees, beginning in 2021, the Company also began making new long-term incentive awards to existing employees in the form of three-year graded vesting stock grants.

Restricted stock grants issued under the 2014 Plan are valued based upon the fair market value of the common shares on the applicable grant date. The restricted stock grants are recorded as deferred compensation in the equity section of the balance sheet on the grant date and then recognized as compensation expense on a straight-line basis over the vesting period of the respective grant. The Company's policy is to adjust compensation expense for forfeitures as they occur.

The following table represents a roll-forward of outstanding restricted stock and related activity for the three months ended March 31, 2022:

	Shares	Weighted-Average Grant Date Price per Share
Outstanding restricted stock as of December 31, 2021	201,170	$	165.61
Grants issued	66,190	176.78
Grants vested	(2,337)	147.66
Grants forfeited	(1,321)	185.09
Total outstanding restricted stock as of March 31, 2022	263,702	$	168.47

As of March 31, 2022, 111,389 common shares remained available for grants under the 2014 Plan.

Total deferred equity compensation related to unvested restricted stock was $24.5 million as of March 31, 2022. The recognition of compensation expense related to deferred compensation over the remaining vesting periods is as follows:

Nine Months   Remaining In
2022		2023		2024		2025		2026		Thereafter		Total

Employee Stock Purchase Plan

Under the Diamond Hill Investment Group, Inc. Employee Stock Purchase Plan (the "ESPP"), eligible employees may purchase shares of the Company's common stock at 85% of the fair market value on the last day of each offering period. Each offering period is approximately three months, which coincides with the Company's fiscal quarters. During the three-month period ended March 31, 2022, ESPP participants purchased 2,335 shares of common stock for $0.4 million, and the Company recorded $0.1 million of share-based payment expense related to these purchases. During the three-month period ended March 31, 2021, ESPP participants purchased 2,583 shares of common stock for $0.3 million, and the Company recorded $0.1 million of share based payment expense related to these purchases.

Stock Grant Transactions

The following table represents common shares issued as part of the Company's incentive compensation program during the three-month periods ended March 31, 2022, and 2021:

March 31, 2021	3,681	$	529,806

401(k) Plan

The Company sponsors a 401(k) plan in which all employees are eligible to participate. Employees may contribute a portion of their compensation subject to certain limits based on federal tax laws. The Company matches employee contributions equal to 250.0% of the first 6.0% of an employee’s compensation contributed to the plan. The Company settles the 401(k) plan matching contributions in cash or common shares of the Company based on the election of the employees.

Deferred Compensation Plans

The Company offers two deferred compensation plans: the Diamond Hill Fixed Term Deferred Compensation Plan and the Diamond Hill Variable Term Deferred Compensation Plan (together, the “Plans”). Under the Plans, participants may elect to voluntarily defer, for a minimum of five years, certain incentive compensation that the Company then contributes into the Plans. Participants are responsible for designating investment options for the assets they contribute, and the distribution paid to each participant reflects any gains or losses on the assets realized in connection with the Plans. Assets held in the Plans are included in the Company’s investment portfolio, and the associated obligation to participants is included in deferred compensation liability. Deferred compensation liability was $34.0 million and $37.3 million as of March 31, 2022 and December 31, 2021, respectively.

Income Taxes

Income Taxes

The Company has determined its interim tax provision projecting an estimated annual effective tax rate.

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

	Three Months Ended   March 31,
	2022		2021
Statutory U.S. federal income tax rate	21.0	%	21.0	%
State and local income taxes, net of federal benefit	4.6	%	4.4	%
Internal revenue code section 162 limitations	1.3	%	1.1	%
Other	(0.9)	%	—	%
Unconsolidated effective income tax rate	26.0	%	26.5	%
Impact attributable to redeemable noncontrolling interest(a)	1.9	%	(0.8)	%
Effective income tax rate	27.9	%	25.7	%

(a) The provision for income taxes includes the impact of the operations of the Consolidated Funds, which are not subject to federal income taxes. Accordingly, a portion of the Company’s earnings are not subject to corporate tax levels.

Absent the impact attributable to redeemable noncontrolling interest, the estimated unconsolidated effective income tax rate would have been 26.0%. The Company's actual effective tax rate for fiscal year ending December 31, 2022 could be materially different from the projected rate as of March 31, 2022.

The net temporary differences incurred to date will reverse in future periods as the Company generates taxable earnings. The Company believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax assets recorded. The Company records a valuation allowance when it is more likely than not that some or all of the deferred tax assets will not be realized. As of March 31, 2022 and December 31, 2021, no valuation allowance was deemed necessary.

FASB ASC 740, Income Taxes, prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return, and also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.  The Company recognizes tax benefits related to positions taken, or expected to be taken, on its tax returns, only if the positions are more likely than not sustainable. Once this threshold has been met, the Company’s measurement of its expected tax benefits is recognized in its financial statements. The Company did not record an accrual for tax-related uncertainties or unrecognized tax positions as of March 31, 2022 or December 31, 2021. The Company did not recognize any interest and penalties during the three months ended March 31, 2022

Sale of Diamond Hill's High Yield-Focused Investment Advisory Contracts

DHCM entered into an asset purchase agreement dated February 2, 2021 (the “Purchase Agreement”) with Brandywine Global Investment Management, LLC (“Brandywine Global”), a specialist investment manager of Franklin Resources, Inc. The transaction closed on July 30, 2021 ("Closing Date"), at which time Brandywine Global acquired the investment advisory contracts of DHCM’s two high yield-focused mutual funds - the Corporate Credit Fund and the High Yield Fund (the “High Yield-Focused Advisory Contracts”).

DHCM determined the gain on this transaction in accordance with ASC 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets. DHCM received an initial cash payment at closing of $9.0 million, which was included in gain on sale of high yield-focused advisory contracts in the Consolidated Statements of Income during the third quarter of 2021.

DHCM may receive two additional payments of up to $13.0 million in the aggregate based on the net revenue of the Corporate Credit Fund and the High Yield Fund on July 30, 2022. The Company has not recorded any additional gain for the two potential

additional payments because this variable consideration is constrained based on movements in the financial markets and the net shareholder flows of the Corporate Credit Fund and the High Yield Fund. Therefore, there can be no reasonable assurance that all or any of these additional payments will be received by DHCM.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited, condensed, and consolidated financial statements for Diamond Hill Investment Group, Inc. and its subsidiaries (referred to in these notes to the condensed consolidated financial statements as "the Company," "management," "we," "us," and "our") as of March 31, 2022 and December 31, 2021, and for the three-month periods ended March 31, 2022 and 2021, have been prepared in accordance with United States generally accepted accounting principles ("GAAP"), the instructions to Form 10-Q, and Article 10 of Securities and Exchange Commission (the "SEC") Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of the financial condition and results of operations as of the dates, and for the interim periods, presented, have been included. These unaudited, condensed, and consolidated financial statements and footnotes should be read in conjunction with the audited consolidated financial statements of the Company included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the "2021 Form 10-K"), as filed with the SEC.

Use of Estimates

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions related to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenue and expense during the period. Actual results could differ from those estimates.

Reclassification

Reclassification

Certain amounts and disclosures for prior periods may have been reclassified to conform to the current period's financial presentation.

Principles of Consolidation

Principles of Consolidation

The accompanying consolidated financial statements include the operations of the Company and its controlled subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

The Company holds certain investments in the Funds and DHMF, for general corporate investment purposes, to provide seed capital for newly formed strategies or to add capital to existing strategies. The Funds are organized in a series fund structure in which there are multiple mutual funds within one Trust. The Trust is an open-end investment company registered under the Investment Advisers Act of 1940, as amended (the "1940 Act"). Each individual Fund represents a separate share class of a legal entity organized under the Trust. DHMF is organized as a Delaware limited partnership and is exempt from registration under the 1940 Act.

The Company performs its consolidation analysis at the individual Fund level and has concluded that the Funds are voting rights entities (“VREs”) because the structure of the Funds is such that the shareholders are deemed to have the power through voting rights to direct the activities that most significantly impact each Fund’s economic performance. To the extent material, these Funds are consolidated if Company ownership, directly or indirectly, represents a majority interest (greater than 50%). The Company records redeemable noncontrolling interests in consolidated investments for which the Company's ownership is less than 100%. As of March 31, 2022, the Company has consolidated the Diamond Hill International Fund and the Diamond Hill Large Cap Concentrated Fund (together, the "Consolidated Funds").

DHCM is the investment manager of DHMF and is the managing member of Diamond Hill Fund GP, LLC (the “General Partner”), which is the general partner of DHMF. DHCM is wholly owned by, and consolidated with, the Company. Further, DHCM, through its control of the General Partner, has the power to direct DHMF’s economic activities and the right to receive investment advisory fees that may be significant from DHMF. DHMF commenced operations on June 1, 2021, and its underlying assets consist primarily of marketable securities.

The Company concluded DHMF was a variable interest entity (“VIE”) given that: (i) DHCM has disproportionately less voting interest than economic interest, and (ii) DHMF's limited partners have full power to remove the General Partner (which is controlled by the Company) due to the existence of substantive kick-out rights. In addition, substantially all of DHMF's activities are conducted on behalf of the General Partner, which has disproportionately few voting rights. The Company concluded it is not the primary beneficiary of DHMF as it lacks the power to control DHMF, since DHMF's limited partners have single-party kick-out rights and can unilaterally remove the General Partner without cause. DHCM’s investments in DHMF are reported as a component of the Company’s investment portfolio and valued at DHCM’s respective share of DHMF's net income or loss.

Gains and losses attributable to changes in the value of DHCM’s interests in DHMF are included in the Company’s reported investment income. The Company’s exposure to loss as a result of its involvement with DHMF is limited to the amount of its investment. DHCM is not obligated to provide, and has not provided, financial or other support to DHMF, except for its investments to date and its contractually provided investment advisory responsibilities. The Company has not provided liquidity arrangements, guarantees, or other commitments to support DHMF’s operations, and DHMF’s creditors and interest holders have no recourse to the general credit of the Company.

Redeemable Noncontrolling Interest

Redeemable Noncontrolling Interest

Redeemable noncontrolling interest represents third-party interests in the Consolidated Funds. This interest is redeemable at the option of the investors, and therefore, is not treated as permanent equity. Redeemable noncontrolling interest is recorded at redemption value, which approximates the fair value each reporting period.

Segment Information

Segment Information

Management has determined that the Company operates in a single business segment, which is providing investment advisory and related services to clients through pooled investment vehicles, including the Funds, DHMF, separately managed accounts, and model delivery programs. Therefore, the Company does not present disclosures relating to operating segments in annual or interim financial statements.

Cash and Cash Equivalents

Cash and Cash EquivalentsCash and cash equivalents include demand deposits and money market mutual funds held by DHCM.

Accounts Receivable

Accounts ReceivableThe Company records accounts receivable when they are due and presents them on 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 the individual or entity that owes the receivable.

Investments

Investments

Management determines the appropriate classification of its investments at the time of purchase and re-evaluates its determination for each reporting period.

Company sponsored investments, where the Company has neither control nor the ability to exercise significant influence, as well as securities held in the Consolidated Funds are measured at fair value based on quoted market prices. Unrealized gains and losses are recorded as investment income (loss) in the Company's consolidated statements of income.

Investments classified as equity method investments represent investments in which the Company owns between 20-50% of the outstanding voting interests in the entity or where it is determined that the Company is able to exercise significant influence but not control over the investments. When using the equity method, the Company recognizes its respective share of the investee's net income or loss for the period, which is recorded as investment income in the Company's consolidated statements of income.

Property and Equipment

Property and Equipment

Property and equipment, consisting of leasehold improvements, right-of-use lease assets, computer equipment, capitalized software, furniture, and fixtures are carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated lives of the assets.

Implementation costs incurred to develop or obtain internal-use software, including hosting arrangements, are capitalized and expensed on a straight-line basis over either the estimated useful life of the respective software or the term of the hosting arrangement.

Property and equipment is tested for impairment when there is an indication that the carrying amount of an asset may not be recoverable. When an asset is determined to not be recoverable, the impairment loss is measured based on the excess, if any, of the carrying value of the asset over its fair value.

Revenue Recognition

Revenue Recognition – GeneralThe Company recognizes revenue when it satisfies performance obligations under the terms of a contract with a client. The Company earns substantially all of its revenue from DHCM investment advisory and fund administration contracts. Investment advisory and administration fees, generally calculated as a percentage of assets under management ("AUM"), are recorded as revenue as services are performed. In addition to fixed fees based on a percentage of AUM, certain client accounts also provide periodic performance-based fees.

Revenue Recognition – Investment Advisory Fees

DHCM's investment advisory contracts with clients have a single performance obligation because the contracted services are not separately identifiable from other obligations in the contracts, and therefore, are not distinct. All obligations to provide investment advisory services are satisfied over time by DHCM, and the Company recognizes revenue through DHCM as time passes.

The fees DHCM receives for its services under its investment advisory contracts are based on AUM, which changes based on the value of securities held under each investment advisory contract. These fees are thereby constrained and represent variable consideration, and they are excluded from revenue until the AUM on which DHCM's client is billed is no longer subject to market fluctuations.

DHCM also provides its strategy model portfolios and related services to sponsors of model delivery programs. For its services, DHCM is paid a model delivery fee by the program sponsor at a pre-determined rate based on the amount of assets in the program. Model delivery program revenues were $1.7 million and $0.9 million for the three months ended March 31, 2022 and 2021, respectively.

Revenue Recognition – Performance-Based Fees

DHCM manages certain client accounts that pay performance-based fees. These fees are calculated based on client investment results over rolling five-year periods. The Company records performance-based fees when it is probable that a significant reversal of the revenue will not occur.

Revenue Recognition – Mutual Fund Administration

DHCM has an administrative and transfer agency services agreement with the Funds under which DHCM performs certain services for each Fund. These services include performance obligations, such as mutual fund administration, fund accounting, transfer agency, and other related functions. These services are performed concurrently under DHCM's agreement with the Funds, all performance obligations to provide these administrative services are satisfied over time, and the Company recognizes the related revenue as time progresses. Each Fund pays DHCM a fee for performing these services, which is calculated using an annual rate multiplied by the average daily net assets of each respective Fund share class. These fees are thereby constrained and represent variable consideration, and they are excluded from revenue until the AUM on which DHCM bills the Funds is no longer subject to market fluctuations.

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 shareholder mailings, federal and state registrations, and legal and audit services. In fulfilling a portion of its role under the administrative and transfer agency services agreement with the Funds, DHCM acts as agent and pays for these services on behalf of the Funds. Each vendor is independently responsible for fulfillment of the services it has been engaged to provide and negotiates its fees and terms directly with the management and board of trustees of the Funds. Each year, the Funds' board of trustees reviews the fee that each Fund pays to DHCM, and specifically considers 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.

Income Taxes

Income Taxes

The Company accounts for current and deferred income taxes through an asset and liability approach. Deferred tax assets are recognized for deductible temporary differences, 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 federal and applicable state and local jurisdictions for various tax periods. 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 it does business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws among those jurisdictions, and 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 positions 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 Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 740, Income Taxes. The Company records interest and penalties within income tax expense on the income statement.

Earnings Per Share

Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period, which includes unvested restricted shares. See Note 9.
