Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events On April 29, 2025, DHIL’s board of directors (“Board”) approved a quarterly cash dividend of $1.50 per share, payable on June 13, 2025, to shareholders of record as of the close of business on June 2, 2025. This dividend is expected to reduce shareholders’ equity by approximately $4.1 million. On April 29, 2025, at the Company's annual meeting of shareholders, shareholders approved the Diamond Hill Investment Group, Inc. 2025 Equity and Cash Incentive Plan (the "2025 Plan"). The 2025 Plan authorizes the issuance of 225,000 DHIL common shares in various forms of equity awards. Previously, the Company issued equity awards under the 2022 Plan. With the approval of the 2025 Plan, there are no longer any common shares available for issuance under the 2022 Plan, although certain grants previously made under the 2022 Plan remain issued and outstanding.
