Notes to Consolidated Financial Statements (unaudited)

Note 1 Business and Organization

Diamond Hill Investment Group, Inc., an Ohio corporation (“DHIL” and, collectively with its subsidiaries, the “Company”), 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. DHCM 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, separately managed accounts, collective investment trusts, other pooled vehicles including sub-advised funds, and model delivery programs.

Note 2 Significant Accounting Policies

Basis of Presentation

The accompanying unaudited, condensed, and consolidated financial statements of the Company as of March 31, 2023 and December 31, 2022, and for the three-month periods ended March 31, 2023 and 2022, 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 Company management (“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, 2022 (the “2022 Form 10-K”), as filed with the SEC.

Operating results for the three-month period ended March 31, 2023, are not necessarily indicative of the results the Company may expect for the full fiscal year ending December 31, 2023, or any subsequent period.

For further information regarding the risks to the Company’s business, refer to the consolidated financial statements and notes thereto in the 2022 Form 10-K, including “Part I – Item 1A. – Risk Factors” of the 2022 Form 10-K, the “Cautionary Note Regarding Forward-Looking Statements” in “Part I – Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023 (this “Form 10-Q”), and “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 requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements as well as the reported amounts of revenue and expense during the reporting period. Estimates have been prepared based on the most current and best available information, but actual results could differ materially from those estimates.

Reclassification

Certain prior period amounts and disclosures 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 DHIL and its controlled subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

DHCM 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”). The Trust is an open-end investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). Each individual Fund represents a separate share class of

7

a legal entity organized under the Trust. DHMF is organized as a Delaware limited partnership and is exempt from registration under the 1940 Act.

DHIL consolidates all subsidiaries and certain investments in which it has a controlling interest. The Company is generally deemed to have a controlling interest when it owns the majority of the voting interest of a voting rights entity (“VRE”) or are deemed to be the primary beneficiary of a variable interest entity (“VIE”). A VIE is an entity that lacks sufficient equity to finance its activities, or any entity whose equity holders do not have defined power to direct the activities of the entity normally associated with an equity investment. The Company’s analysis to determine whether an entity is a VIE or a VRE involves judgment and considers several factors, including an entity’s legal organization, equity structure, the rights of the investment holders, the Company’s ownership interest in the entity, and the Company’s contractual involvement with the entity. The Company continually reviews and reconsiders its VIE or VRE conclusions upon the occurrence of certain events, such as changes to its ownership interest, or amendments to contract documents.

The Company performs its consolidation analysis at the individual Fund level and has concluded that the Funds are 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, the 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%. The Company de-consolidated the Diamond Hill Large Cap Concentrated Fund during the year ended December 31, 2022, as the Company’s ownership declined to less than 50% during 2022. As of December 31, 2022 and March 31, 2023, the Company has consolidated the Diamond Hill International Fund. During the three months ended March 31, 2022, the Company consolidated the Diamond Hill International Fund as well as the Diamond Hill Large Cap Concentrated Fund (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 from DHMF that may be significant. DHMF commenced operations on June 1, 2021, and its underlying assets consist primarily of marketable securities.

The Company concluded DHMF was a 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 vehicles, including the Funds and DHMF, collective investment trusts, separately managed accounts, model delivery programs, and other pooled vehicles including sub-advised funds. Therefore, the Company does not present disclosures relating to operating segments in annual or interim financial statements.

8

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and money market mutual funds held by DHCM. The Company considers all highly liquid temporary cash instruments with an original maturity of three months or less to be cash equivalents. The Company places its cash on deposit with financial institutions in the United States, which are insured by the Federal Deposit Insurance Corporation ("FDIC") up to $250,000. The Company's credit risk in the event of failure of these financial institutions is represented by the difference between the FDIC limit and the total amounts on deposit. Management monitors the financial institutions’ creditworthiness in conjunction with balances on deposit to minimize risk. The Company from time to time may have amounts on deposit in excess of the insured limits. As of March 31, 2023, the Company had $1.7 million and $38.6 million in demand deposits and money market mutual funds, respectively. As of December 31, 2022, the Company had $2.8 million and $60.4 million in demand deposits and money market mutual funds, respectively.

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, 2023, or December 31, 2022. Accounts receivable from the Funds were $8.9 million as of March 31, 2023, and $9.3 million as of December 31, 2022.

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 the control nor the ability to exercise significant influence, as well as securities held in the Consolidated Fund, 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 20% to 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 (loss) 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 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.

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 under advisement (“AUA”) in the program.

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 period ended March 31, 2023 or the three-month period ended March 31, 2022. After the initial five-year contract measurement term, the performance-based fee is calculated annually based on the client investment results over the recently completed five-year period. 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, 2023:

	As of March 31, 2023
	AUM subject to performance-based fees		Unearned performance-based fees
Contractual Measurement Period Ending:
Quarter Ending September 30, 2023	$	451,836,353	$	547,410
Total	$	451,836,353	$	547,410

The contractual end date highlights 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, 2023 will increase or decrease based on future client investment results through the contractual period end.

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 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 Funds’ management and board of trustees. 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,
	2023		2022
Mutual fund administration:
Administration revenue, gross	$	5,416,875	$	6,940,172
Fund related expense	(3,468,831)		(3,962,672)
Mutual fund administration revenue, net	$	1,948,044	$	2,977,500

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 materially 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 and diluted earnings per share are computed by dividing net income attributable to common shareholders 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, 2023, 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 financial statements, including those 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, 2023:

	Level 1		Level 2		Level 3	Total
Cash equivalents	$	38,627,607	—		—	$	38,627,607
Fair value investments:
Securities held in Consolidated Funds(a)	$	24,564,417	$	36,408,760	—	$	60,973,177
Company-sponsored investments	$	68,301,102	—		—	$	68,301,102

(a) Of the securities held in the Consolidated Funds as of March 31, 2023, the Company directly held $40.4 million and noncontrolling shareholders held $20.6 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 14, 2023, 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 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 during the three months ended March 31, 2023, and no borrowings were outstanding as of March 31, 2023.

Note 6 Compensation Plans

Share-Based Payment Transactions

The Company maintains the shareholder-approved Diamond Hill Investment Group, Inc. 2022 Equity and Cash Incentive Plan (the “2022 Plan”), which authorizes the issuance of 300,000 common shares of DHIL stock in various forms of equity awards. As of March 31, 2023, there were 243,580 common shares available for grants under the 2022 Plan. Previously, the Company issued equity awards under the Diamond Hill Investment Group, Inc. 2014 Equity and Cash Incentive Plan (the “2014 Plan”). There are no longer any common shares available for issuance under the 2014 Plan, although grants previously made under the 2014 Plan remain issued and outstanding.

15

Restricted stock grants represent common shares issued and outstanding upon grant subject to vesting restrictions. The Company issues restricted stock grants that cliff vest after five years to all new employees upon hire and additional awards annually to key employees in the form of three-year graded vesting stock grants.

Restricted stock grants 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, 2023:

	Shares	Weighted-Average Grant Date Price per Share
Outstanding restricted stock as of December 31, 2022	219,459	$	165.62
Grants issued	49,099	191.47
Grants vested	(14,000)	211.83
Grants forfeited	—	—
Total outstanding restricted stock as of March 31, 2023	254,558	$	168.06

Total deferred equity compensation related to unvested restricted stock was $23.6 million as of March 31, 2023. The recognition of compensation expense related to deferred compensation over the remaining vesting periods is as follows:

Nine Months   Remaining In
2023		2024		2025		2026		2027		Thereafter	Total
$	9,035,909	$	8,786,455	$	4,524,579	$	1,085,868	$	135,745	—	$	23,568,556

Employee Stock Purchase Plan

Under the Diamond Hill Investment Group, Inc. Employee Stock Purchase Plan (the “ESPP”), eligible employees may purchase shares of DHIL 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, 2023, ESPP participants purchased 1,963 shares of common stock for $0.3 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, 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.

March 31, 2022	2,743	$	487,870

16

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 “DC Plans”). Under the DC Plans, participants may elect to voluntarily defer, for a minimum of five years, certain incentive compensation that the Company then contributes into the DC 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 DC Plans. Assets held in the DC 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 $31.2 million and $30.7 million as of March 31, 2023 and December 31, 2022, respectively.

Note 7 Operating Lease

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

As of March 31, 2023, the carrying value of this right-of-use asset, which is included in property and equipment, was approximately $1.0 million net of deferred rent on the consolidated balance sheets. As of March 31, 2023, the carrying value of the lease liability was approximately $1.2 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, 2023 and 2022:

	March 31, 2023		March 31, 2022

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,
	2023		2022
Statutory U.S. federal income tax rate	21.0	%	21.0	%
State and local income taxes, net of federal benefit	4.8	%	4.6	%
Internal revenue code section 162 limitations	1.5	%	1.3	%
Other	0.6	%	(0.9)	%
Unconsolidated effective income tax rate	27.9	%	26.0	%
Impact attributable to redeemable noncontrolling interest(a)	(2.0)	%	1.9	%
Effective income tax rate	25.9	%	27.9	%

(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.

The Company’s actual effective tax rate for the fiscal year ending December 31, 2023 could be materially different from the projected rate as of March 31, 2023.

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, 2023 and December 31, 2022, 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, 2023 or December 31, 2022.

The Company did not recognize any interest and penalties during the three months ended March 31, 2023.

18

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 earnings per share (“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,
	2023		2022
Net Income	$	14,103,047	$	8,275,016
Less: Net (income) loss attributable to redeemable noncontrolling interest	(1,395,495)		854,936
Net income attributable to common shareholders	$	12,707,552	$	9,129,952
Weighted average number of outstanding shares - Basic	3,025,094		3,185,930
Weighted average number of outstanding shares - Diluted	3,025,094		3,185,930
Earnings per share attributable to common shareholders
Basic	$	4.20	$	2.87
Diluted	$	4.20	$	2.87

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 incidental to its business. There are currently no such legal matters pending that the Company believes will have a material adverse effect on its consolidated financial statements. However, litigation involves an element of uncertainty, and future developments could cause legal actions or claims to have a material adverse effect on the Company’s financial condition, results of operations, and liquidity.

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 full or partial coverage against certain of these liabilities.

19

Note 11 Subsequent Events

On May 10, 2023, DHIL’s board of directors (“Board”) approved a quarterly cash dividend of $1.50 per share, payable on June 16, 2023, to shareholders of record as of June 1, 2023. This dividend is expected to reduce shareholders’ equity by approximately $4.5 million.

General

The Company derives its consolidated revenue and net income from investment advisory and fund administration services provided by DHCM. DHCM is a registered investment adviser under the 1940 Act, and is the investment adviser and administrator for the Diamond Hill Funds. DHCM also provides investment advisory and related services to DHMF, a private fund, as well as separately managed accounts, collective investment trusts, model delivery programs and other pooled vehicles, including sub-advised funds.

The Company believes focusing 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.

The Company accomplishes this through its shared investment principles, including: (i) valuation-disciplined active portfolio management, (ii) fundamental bottom-up research, (iii) a long-term, business owner mindset, and (iv) a client alignment philosophy that ensures clients’ interests come first. Client alignment is emphasized through: (i) a strategic capacity discipline that protects portfolio managers’ abilities to generate excess returns, (ii) personal investment by the Company’s portfolio

21

managers in the strategies they manage, (iii) portfolio manager compensation being driven by long-term investment results in client portfolios, and (iv) a fee philosophy focused on a fair sharing of the economics among clients, employees, and shareholders. The Company’s core cultural values of curiosity, ownership, trust, and respect create an environment where investment professionals focus on investment results and all teammates focus on the overall client experience.

The Company offers a variety of investment strategies designed for long-term strategic allocations from institutionally-oriented investors in key asset classes, aligning its investment team’s competitive advantages with its clients’ needs.

Assets Under Management

DHCM’s principal source of revenue is investment advisory fee income earned from managing client accounts under investment advisory and sub-advisory agreements. The fees earned depend on the type of investment strategy, account size, and servicing requirements. DHCM’s revenues depend largely on the total value and composition of its AUM. Accordingly, net cash flows from clients, market fluctuations, and the composition of AUM impact the Company’s revenues and results of operations. The Company also has certain agreements that allow it to earn performance-based fees if investment returns exceed targeted amounts over a specified measurement period.

Model Delivery Programs - Assets Under Advisement

DHCM provides strategy-specific model portfolios to sponsors of model delivery programs. DHCM is paid for its services by the program sponsors at a pre-determined rate based on AUA in the model delivery programs. DHCM does not have discretionary investment authority over individual client accounts in the model delivery programs, and therefore, the AUA are not included in the Company’s AUM.

The Company’s revenues are highly dependent on both the value and composition of AUM and AUA. The following is a summary of the Company’s AUM by product and investment objective, a roll-forward of the change in AUM, and a summary of AUA for the three-month periods ended March 31, 2023 and 2022:

Summary Discussion of Consolidated Results of Operations - Three Months Ended March 31, 2023, compared with Three Months Ended March 31, 2022

Revenue for the three months ended March 31, 2023 decreased $8.3 million or 20%, compared to revenue for the same period in 2022, primarily due to a 16% decrease in average AUM and AUA. The average advisory fee rate also decreased from 0.49% for the three months ended March 31, 2022 to 0.48% for the three months ended March 31, 2023.

Operating profit margin was 32% for the three months ended March 31, 2023, and 45% for the three months ended March 31, 2022. Adjusted operating profit margin was 35% for the three months ended March 31, 2023, and 43% for the three months ended March 31, 2022. Adjusted operating profit margin excludes the impact of market movements on the deferred compensation liability and related economic hedges, and the impact of the Consolidated Funds. See the “Non-GAAP Financial Measures and Reconciliation” section within this Form 10-Q.

The Company expects that its operating margin will fluctuate period over period based on various factors, including revenues, investment results in the strategies the Company manages, employee performance, staffing levels, and gains and losses on investments held in the DC Plans.

The Company had $8.1 million in investment income due to market appreciation for the three months ended March 31, 2023, compared to investment losses of $7.6 million due to market depreciation for the three months ended March 31, 2022.

Income tax expense increased $1.7 million for the three months ended March 31, 2023, compared to the three months ended March 31, 2022. The increase in income tax expense was primarily due to the increase in the Company’s income before taxes.

The Company generated net income attributable to common shareholders of $12.7 million ($4.20 per diluted share) for the three months ended March 31, 2023, compared with net income attributable to common shareholders of $9.1 million ($2.87 per diluted share) for the same period in 2022. The increase in net income attributable to common shareholders period-over-period was primarily due to investment income for the three months ended March 31, 2023, compared to investment losses for the three months ended March 31, 2022.

Revenue

	Three Months Ended   March 31,
(in thousands, except percentages)	2023		2022		% Change
Investment advisory	$	32,042	$	39,279	(18)	%
Mutual fund administration, net	1,949		2,977		(35)	%
Total	$	33,991	$	42,256	(20)	%

Investment Advisory Fees. Investment advisory fees for the three months ended March 31, 2023, decreased $7.2 million, or 18%, compared to the three months ended March 31, 2022. 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 decrease in investment advisory fees was primarily due to a decrease in average AUM of 16% and a decrease in the average advisory fee rate from 0.49% to 0.48% period-over-period. The average advisory fee rate is calculated by dividing investment advisory revenues by total average AUM and AUA during the period (annualized for all periods less than one year).

Mutual Fund Administration Fees. Mutual fund administration fees for the three months ended March 31, 2023, decreased $1.0 million, or 35%, compared to the three months ended March 31, 2022. Mutual fund administration fees include administration fees received from the Funds, which are calculated as a percentage of the Funds’ average AUM. This decrease was primarily due to a 22% decrease in the Funds' average AUM from the three months ended March 31, 2022, to the three months ended March 31, 2023, and an increase in administration fees paid on behalf of the Funds as a percentage of average Fund AUM

Expenses

	Three Months Ended   March 31,
(in thousands, except percentages)	2023		2022		% Change
Compensation and related costs, excluding deferred compensation expense (benefit)	$	16,363	$	18,647	(12)	%
Deferred compensation expense (benefit)	745		(1,179)		NM

Mutual fund administration	782		818		(4)	%
Total	$	23,049	$	23,183	(1)	%

Compensation and Related Costs, Excluding Deferred Compensation Expense (Benefit). Employee compensation and benefits for the three months ended March 31, 2023 decreased by $2.3 million compared to the three months ended March 31, 2022. This decrease was due to a decrease in accrued incentive compensation of $3.1 million partially offset by an increase in salary and related benefits of $0.3 million and an increase in restricted stock expense of $0.5 million related to the Company’s annual long-term incentive awards. 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 expense was $0.7 million for the three months ended March 31, 2023, compared to a benefit of $1.2 million for the three months ended March 31, 2022, primarily due to market appreciation / depreciation on the DC Plan’s investments period-over-period.

The gain (loss) on DC Plan’s 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 (loss) 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, 2023, increased by $0.3 million, or 10%, compared to the three months ended March 31, 2022. The increase was primarily due to a $0.3 million increase in investment research expenses.

Sales and Marketing. Sales and marketing expense for the three months ended March 31, 2023, decreased by $0.1 million, or 3%, compared to the three months ended March 31, 2022. The decrease was primarily due to decreased payments made to third-party intermediaries related to the sale of the Funds on their platforms.

26

Mutual Fund Administration. Mutual fund administration expenses for the three months ended March 31, 2023, decreased by less than $0.1 million, or 4%, compared to the three months ended March 31, 2022. Mutual fund administration expenses consist of both variable and fixed expenses. The decrease was primarily due to a reduction in the Funds’ average AUM period-over-period.

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 $165.1 million and $182.9 million of total assets as of March 31, 2023, and December 31, 2022, 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 27,706 of its common shares during the three months ended March 31, 2023, for a total of $4.6 million. As of March 31, 2023, $10.8 million remains available for repurchases under the Company’s current repurchase program. See “Part II - Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds” for a description of the current 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 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, 2023 is presented below:

Dividend	Declaration Date	Date Paid	Dividend Amount (in millions)
First quarter - $1.50 per share	February 24, 2023	March 17, 2023	$	4.6

On May 10, 2023, the Board approved a regular quarterly dividend for the second quarter of 2023 of $1.50 per share. The regular dividend will be paid on June 16, 2023, to shareholders of record as of June 1, 2023. This regular dividend is expected to reduce shareholders’ equity by approximately $4.5 million.

Working Capital

As of March 31, 2023, the Company had working capital of approximately $152.1 million, compared to $144.9 million as of December 31, 2022. 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.

Below is a summary of investments as of March 31, 2023 and December 31, 2022.

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, 2023, net cash used in operating activities totaled $13.8 million. Cash used in operating activities were primarily driven by a $26.0 million decrease in the incentive compensation accrual due to the annual incentive compensation payment made in the first quarter of 2023, the net change in securities held by the Consolidated Funds of $1.3 million, and the cash impact of timing differences in the settlement of other assets and liabilities of $3.8 million. These outflows were partially offset by net income of $14.1 million, and non-cash adjustments added back to net income consisting of share-based compensation of $2.9 million, and depreciation of $0.3 million. Net cash used in operating activities of $13.8 million is inclusive of $1.2 million of cash used in operations by the Consolidated Funds.

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, the 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. Net cash used in operating activities of $13.7 million is inclusive of $3.8 million of cash used in operations by the Consolidated Funds.

Cash Flows from Investing Activities

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

Cash flows used in investing activities totaled $0.9 million for the three months ended March 31, 2023. Cash flows used in investing activities were driven by purchases of Company-sponsored investments of $5.3 million which were partially offset by proceeds from the sale of Company-sponsored investments totaling $4.4 million. During the three months ended March 31, 2023, all purchases and sales of investments were in the Company's DC Plans.

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.

Cash Flows from Financing Activities

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

28

For the three months ended March 31, 2023, net cash used in financing activities totaled $8.2 million, consisting of cash outflows for repurchases of the Company’s common stock of $4.6 million, the payment of quarterly dividends totaling $4.6 million, and the value of shares withheld to cover employee tax withholding obligations of $1.1 million. These cash outflows were partially offset by net subscriptions received in the Consolidated Funds from redeemable noncontrolling interest holders of $1.8 million and proceeds received under the ESPP of $0.3 million.

For the three months ended March 31, 2022, net cash used in financing activities totaled $9.9 million, consisting of cash outflows for repurchases of the DHIL 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.

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 the Company’s general creditors.

The following table summarizes the condensed cash flows for the three months ended March 31, 2023, that are attributable to the Company and to the Consolidated Funds, and the related eliminations required in preparing the consolidated statements.

Non-GAAP Financial Measures and Reconciliation

As supplemental information, the Company is providing certain financial measures that are based on methodologies other than GAAP (“non-GAAP”). Management believes the non-GAAP financial measures below are useful measures of the Company’s core business activities, are important metrics in estimating the value of an asset management business, and help facilitate comparisons to Company operating performance across periods. These non-GAAP financial 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 schedules reconcile financial measures calculated in accordance with GAAP to non-GAAP financial measures for the three-month periods ended March 31, 2023 and 2022, respectively.

	Three Months Ended March 31, 2023

Non-GAAP Adjustments:
Deferred compensation liability(1)	1,179		(1,179)		1,179		—		—		—		(2)	%
Consolidated Funds(2)	—		123		3,241		652		1,857		0.58		—

Adjusted Non-GAAP basis	$	24,362	$	18,017	$	—	$	4,683	$	13,334	$	4.19	43	%

(1) This non-GAAP adjustment removes the compensation expense resulting from market valuation changes in the deferred compensation plan liability and the related net gains/losses on investments designated as an economic hedge against the related liability. Amounts deferred under the deferred compensation plans are adjusted for appreciation/depreciation of investments chosen by participants. The Company believes it is useful to offset the non-operating investment income or loss realized on the hedges against the related compensation expense and remove the net impact to help readers understand the Company’s core operating results and to improve comparability from period to period.

(2) This non-GAAP adjustment removes the impact that the Consolidated Funds have on the Company’s GAAP consolidated statements of income. Specifically, the Company adds back the operating expenses and subtracts the investment income of the Consolidated Funds. The adjustment to net operating income represents the operating expenses of the Consolidated Funds, net of the elimination of related management and administrative fees. The adjustment to net income attributable to common shareholders represents the net income of the Consolidated Funds, net of redeemable non-controlling interests. The Company believes removing the impact of the Consolidated Funds helps readers understand its core operating results and improves comparability from period to period .

30

(3) This non-GAAP adjustment represents the net gains/losses earned on the Company’s non-consolidated investment portfolio that are not designated as economic hedges of the deferred compensation plan liability, non-consolidated seed investments, and other investments. The Company believes adjusting for these non-operating income or loss items helps readers understand the Company’s core operating results and improves comparability from period to period.

(4) The income tax expense impacts were calculated and resulted in an overall non-GAAP effective tax rate of 27.9% for the three months ended March 31, 2023 and 26.0% for the three months ended March 31, 2022.

Critical Accounting Policies and Estimates

The preparation of financial statements requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures of contingent assets and liabilities. The Company evaluates such estimates, judgments, and assumptions on an ongoing basis, and bases its estimates, judgements, and assumptions on historical experiences, current trends, and various other factors that it believes to be reasonable under the circumstances. By their nature, these estimates, judgments, and assumptions are subject to uncertainty, and actual results may differ materially from these estimates.

For a summary of the critical accounting policies important to understanding the condensed consolidated financial statements, please see Note 2, Significant Accounting Policies, in “Part I - Item 1 - Financial Statements” of this Form 10-Q, and Critical Accounting Policies and Estimates in “Part I - Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q, as well as Note 2, Significant Accounting Policies, in “Part II - Item 8 - Financial Statements and Supplementary Data” in the 2022 Form 10-K.

There have been no material changes to the Company’s critical accounting estimates during the quarter ended March 31, 2023, as compared to those disclosed in Critical Accounting Policies and Estimates in “Part II - Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the 2022 Form 10-K.

ITEM 4: Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Management, including the Chief Executive Officer and the Chief Financial Officer, has conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act) as of the end of the period covered by this Form 10-Q (the “Evaluation Date”).  Based on such evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures were effective to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and to ensure that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the Company’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, the Company’s management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal controls over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2023, that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

There have been no material changes to the Company’s risk factors from the information disclosed in Item 1A of the 2022 Form 10-K.

ITEM 2: Unregistered Sales of Equity Securities and Use of Proceeds

During the quarter ended March 31, 2023, DHIL did not sell any shares of its common stock that were not registered under the Securities Act. The following table sets forth information regarding repurchases of DHIL common stock during the quarter ended March 31, 2023:

Period	Total Number of Shares Purchased (a)	Average Price Paid Per Share		Total Number of Shares  Purchased as part of Publicly Announced Programs(b)	Approximate Dollar Value of Shares that May Yet Be Purchased Under the Programs(b)
January 1, 2023 through January 31, 2023	6,121	$	185.02	—	$	15,375,875
February 1, 2023 through February 28, 2023	—	—		—	15,375,875
March 1, 2023 through March 31, 2023	27,706	$	164.95	27,706	10,805,749
Total	33,827			27,706	$	10,805,749

(a)The Company regularly withholds shares for tax payments due upon the vesting of employee restricted stock. During the quarter ended March 31, 2023, the Company withheld 6,121 shares of DHIL common stock for employee tax withholding obligations at an average price paid per share of $185.02.

(b)On February 25, 2022, the Board authorized management to repurchase up to $50.0 million of DHIL common shares (the “2022 Repurchase Program”).

On May 10, 2023, the Board terminated the 2022 Repurchase Program and approved a new repurchase plan, authorizing management to repurchase up to $50 million of DHIL common shares in the open market and in private transactions in accordance with applicable securities laws (the “2023 Repurchase Program”). The 2023 Repurchase Program will expire on May 10, 2025, or upon the earlier completion of all authorized purchases under the program.

In connection with the 2022 Repurchase Program, the Company had entered into a Rule 10b5-1 trading plan. This plan was intended to qualify for the safe harbor under Rule 10b5-1 of the Exchange Act.  A Rule 10b5-1 trading 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 trading 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 under the 2022 Repurchase Program were, and purchases under the 2023 Repurchase Program may be, made in the open market or through privately negotiated transactions. Purchases in the open market are intended to comply with Rule 10b-18 under the Exchange Act.

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 incidental to its business. There are currently no such legal matters pending that the Company believes will have a material adverse effect on its consolidated financial statements. However, litigation involves an element of uncertainty, and future developments could cause legal actions or claims to have a material adverse effect on the Company’s financial condition, results of operations, and liquidity.

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 full or partial coverage against certain of these liabilities.

Basis of Presentation

The accompanying unaudited, condensed, and consolidated financial statements of the Company as of March 31, 2023 and December 31, 2022, and for the three-month periods ended March 31, 2023 and 2022, 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 Company management (“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, 2022 (the “2022 Form 10-K”), as filed with the SEC.

Operating results for the three-month period ended March 31, 2023, are not necessarily indicative of the results the Company may expect for the full fiscal year ending December 31, 2023, or any subsequent period.

For further information regarding the risks to the Company’s business, refer to the consolidated financial statements and notes thereto in the 2022 Form 10-K, including “Part I – Item 1A. – Risk Factors” of the 2022 Form 10-K, the “Cautionary Note Regarding Forward-Looking Statements” in “Part I – Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023 (this “Form 10-Q”), and “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 requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements as well as the reported amounts of revenue and expense during the reporting period. Estimates have been prepared based on the most current and best available information, but actual results could differ materially from those estimates.

Reclassification

Certain prior period amounts and disclosures 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 DHIL and its controlled subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

DHCM 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”). The Trust is an open-end investment company registered under the Investment Company 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.

DHIL consolidates all subsidiaries and certain investments in which it has a controlling interest. The Company is generally deemed to have a controlling interest when it owns the majority of the voting interest of a voting rights entity (“VRE”) or are deemed to be the primary beneficiary of a variable interest entity (“VIE”). A VIE is an entity that lacks sufficient equity to finance its activities, or any entity whose equity holders do not have defined power to direct the activities of the entity normally associated with an equity investment. The Company’s analysis to determine whether an entity is a VIE or a VRE involves judgment and considers several factors, including an entity’s legal organization, equity structure, the rights of the investment holders, the Company’s ownership interest in the entity, and the Company’s contractual involvement with the entity. The Company continually reviews and reconsiders its VIE or VRE conclusions upon the occurrence of certain events, such as changes to its ownership interest, or amendments to contract documents.

The Company performs its consolidation analysis at the individual Fund level and has concluded that the Funds are 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, the 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%. The Company de-consolidated the Diamond Hill Large Cap Concentrated Fund during the year ended December 31, 2022, as the Company’s ownership declined to less than 50% during 2022. As of December 31, 2022 and March 31, 2023, the Company has consolidated the Diamond Hill International Fund. During the three months ended March 31, 2022, the Company consolidated the Diamond Hill International Fund as well as the Diamond Hill Large Cap Concentrated Fund (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 from DHMF that may be significant. DHMF commenced operations on June 1, 2021, and its underlying assets consist primarily of marketable securities.

The Company concluded DHMF was a 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 vehicles, including the Funds and DHMF, collective investment trusts, separately managed accounts, model delivery programs, and other pooled vehicles including sub-advised funds. 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. The Company considers all highly liquid temporary cash instruments with an original maturity of three months or less to be cash equivalents. The Company places its cash on deposit with financial institutions in the United States, which are insured by the Federal Deposit Insurance Corporation ("FDIC") up to $250,000. The Company's credit risk in the event of failure of these financial institutions is represented by the difference between the FDIC limit and the total amounts on deposit. Management monitors the financial institutions’ creditworthiness in conjunction with balances on deposit to minimize risk. The Company from time to time may have amounts on deposit in excess of the insured limits. As of March 31, 2023, the Company had $1.7 million and $38.6 million in demand deposits and money market mutual funds, respectively. As of December 31, 2022, the Company had $2.8 million and $60.4 million in demand deposits and money market mutual funds, respectively.

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, 2023, or December 31, 2022. Accounts receivable from the Funds were $8.9 million as of March 31, 2023, and $9.3 million as of December 31, 2022.

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 the control nor the ability to exercise significant influence, as well as securities held in the Consolidated Fund, 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 20% to 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 (loss) 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, 2023 and 2022 under contracts with clients include:

	Three Months Ended March 31, 2023
	Investment advisory		Mutual fund administration, net		Total revenue
Diamond Hill Funds	$	21,383,543	$	1,948,044	$	23,331,587

Collective investment trusts	545,495		—		545,495
	$	39,278,886	$	2,977,500	$	42,256,386

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.

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 under advisement (“AUA”) in the program.

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 period ended March 31, 2023 or the three-month period ended March 31, 2022. After the initial five-year contract measurement term, the performance-based fee is calculated annually based on the client investment results over the recently completed five-year period. 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, 2023:

	As of March 31, 2023
	AUM subject to performance-based fees		Unearned performance-based fees
Contractual Measurement Period Ending:
Quarter Ending September 30, 2023	$	451,836,353	$	547,410
Total	$	451,836,353	$	547,410

The contractual end date highlights 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, 2023 will increase or decrease based on future client investment results through the contractual period end.

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 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 Funds’ management and board of trustees. 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,
	2023		2022
Mutual fund administration:
Administration revenue, gross	$	5,416,875	$	6,940,172
Fund related expense	(3,468,831)		(3,962,672)
Mutual fund administration revenue, net	$	1,948,044	$	2,977,500

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 materially 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 and diluted earnings per share are computed by dividing net income attributable to common shareholders 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, 2023, 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 financial statements, including those 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, 2023:

Share-Based Payment Transactions

The Company maintains the shareholder-approved Diamond Hill Investment Group, Inc. 2022 Equity and Cash Incentive Plan (the “2022 Plan”), which authorizes the issuance of 300,000 common shares of DHIL stock in various forms of equity awards. As of March 31, 2023, there were 243,580 common shares available for grants under the 2022 Plan. Previously, the Company issued equity awards under the Diamond Hill Investment Group, Inc. 2014 Equity and Cash Incentive Plan (the “2014 Plan”). There are no longer any common shares available for issuance under the 2014 Plan, although grants previously made under the 2014 Plan remain issued and outstanding.

Restricted stock grants represent common shares issued and outstanding upon grant subject to vesting restrictions. The Company issues restricted stock grants that cliff vest after five years to all new employees upon hire and additional awards annually to key employees in the form of three-year graded vesting stock grants.

Restricted stock grants 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, 2023:

	Shares	Weighted-Average Grant Date Price per Share
Outstanding restricted stock as of December 31, 2022	219,459	$	165.62
Grants issued	49,099	191.47
Grants vested	(14,000)	211.83
Grants forfeited	—	—
Total outstanding restricted stock as of March 31, 2023	254,558	$	168.06

Total deferred equity compensation related to unvested restricted stock was $23.6 million as of March 31, 2023. The recognition of compensation expense related to deferred compensation over the remaining vesting periods is as follows:

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 “DC Plans”). Under the DC Plans, participants may elect to voluntarily defer, for a minimum of five years, certain incentive compensation that the Company then contributes into the DC 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 DC Plans. Assets held in the DC 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 $31.2 million and $30.7 million as of March 31, 2023 and December 31, 2022, respectively.

Income Tax Disclosure [Abstract]

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,
	2023		2022
Statutory U.S. federal income tax rate	21.0	%	21.0	%
State and local income taxes, net of federal benefit	4.8	%	4.6	%
Internal revenue code section 162 limitations	1.5	%	1.3	%
Other	0.6	%	(0.9)	%
Unconsolidated effective income tax rate	27.9	%	26.0	%
Impact attributable to redeemable noncontrolling interest(a)	(2.0)	%	1.9	%
Effective income tax rate	25.9	%	27.9	%

(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.

The Company’s actual effective tax rate for the fiscal year ending December 31, 2023 could be materially different from the projected rate as of March 31, 2023.

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, 2023 and December 31, 2022, 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, 2023 or December 31, 2022.

The Company did not recognize any interest and penalties during the three months ended March 31, 2023

Basis of Presentation

Basis of Presentation

The accompanying unaudited, condensed, and consolidated financial statements of the Company as of March 31, 2023 and December 31, 2022, and for the three-month periods ended March 31, 2023 and 2022, 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 Company management (“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, 2022 (the “2022 Form 10-K”), as filed with the SEC.

Use of Estimates

Use of Estimates

The preparation of the condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements as well as the reported amounts of revenue and expense during the reporting period. Estimates have been prepared based on the most current and best available information, but actual results could differ materially from those estimates.

Reclassification

Reclassification

Certain prior period amounts and disclosures 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 DHIL and its controlled subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

DHCM 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”). The Trust is an open-end investment company registered under the Investment Company 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.

DHIL consolidates all subsidiaries and certain investments in which it has a controlling interest. The Company is generally deemed to have a controlling interest when it owns the majority of the voting interest of a voting rights entity (“VRE”) or are deemed to be the primary beneficiary of a variable interest entity (“VIE”). A VIE is an entity that lacks sufficient equity to finance its activities, or any entity whose equity holders do not have defined power to direct the activities of the entity normally associated with an equity investment. The Company’s analysis to determine whether an entity is a VIE or a VRE involves judgment and considers several factors, including an entity’s legal organization, equity structure, the rights of the investment holders, the Company’s ownership interest in the entity, and the Company’s contractual involvement with the entity. The Company continually reviews and reconsiders its VIE or VRE conclusions upon the occurrence of certain events, such as changes to its ownership interest, or amendments to contract documents.

The Company performs its consolidation analysis at the individual Fund level and has concluded that the Funds are 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, the 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%. The Company de-consolidated the Diamond Hill Large Cap Concentrated Fund during the year ended December 31, 2022, as the Company’s ownership declined to less than 50% during 2022. As of December 31, 2022 and March 31, 2023, the Company has consolidated the Diamond Hill International Fund. During the three months ended March 31, 2022, the Company consolidated the Diamond Hill International Fund as well as the Diamond Hill Large Cap Concentrated Fund (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 from DHMF that may be significant. DHMF commenced operations on June 1, 2021, and its underlying assets consist primarily of marketable securities.

The Company concluded DHMF was a 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 vehicles, including the Funds and DHMF, collective investment trusts, separately managed accounts, model delivery programs, and other pooled vehicles including sub-advised funds. 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. The Company considers all highly liquid temporary cash instruments with an original maturity of three months or less to be cash equivalents. The Company places its cash on deposit with financial institutions in the United States, which are insured by the Federal Deposit Insurance Corporation ("FDIC") up to $250,000. The Company's credit risk in the event of failure of these financial institutions is represented by the difference between the FDIC limit and the total amounts on deposit. Management monitors the financial institutions’ creditworthiness in conjunction with balances on deposit to minimize risk. The Company from time to time may have amounts on deposit in excess of the insured limits.

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 the control nor the ability to exercise significant influence, as well as securities held in the Consolidated Fund, 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 20% to 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 (loss) 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.

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 under advisement (“AUA”) in the program.

Revenue Recognition – Performance-Based FeesDHCM 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

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 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 Funds’ management and board of trustees. 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 materially 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 and diluted earnings per share are computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding for the period, which includes unvested restricted shares. See Note 9.
