Accounting Policies [Abstract] |
Summary of significant accounting policies and estimates | Summary of significant accounting policies and estimates Basis of Presentation The accompanying condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC") regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America ("U.S. GAAP") and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 (the "Form 10-K"). The accompanying condensed consolidated balance sheet data was derived from the same sources as the audited consolidated financial statements but does not include all disclosures required by U.S. GAAP for annual financial statement purposes. The accompanying condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. Certain reclassifications have been made to prior periods to place them on a basis comparable with current period presentation. Preparing financial statements requires management to make estimates and assumptions that affect the amounts that are reported in the financial statements and the accompanying disclosures. Although these estimates are based on management's knowledge of current events and actions that the Company may undertake in the future, actual results may differ materially from the estimates. The condensed consolidated results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for any future interim or annual period. Oppenheimer Acquisition Corp. I On October 26, 2021, OPY Acquisition Corp. I (“OHAA”), a special purpose acquisition company, consummated its $126.5 million initial public offering (the “OHAA IPO”). OPY Acquisition LLC I (the “Sponsor”), a Delaware series limited liability company and the Company’s subsidiary was the sponsor of and consolidated OHAA. Upon IPO completion, funds totaling $127.8 million, including proceeds from the OHAA IPO of $126.5 million and $1.3 million investment from the Sponsor, were held in a trust account until the earlier of (i) the completion of a Business Combination or (ii) ten business days after April 29, 2023, 18 months from the closing of the OHAA IPO (“Combination Period”), pursuant to OHAA's certificate of incorporation. On October 26, 2023, OHAA’s stockholders approved an amendment to its certificate of incorporation to extend the deadline by which it must complete its initial business combination from October 30, 2023 to June 30, 2024 on a month-to-month basis. In the fourth quarter of 2023, a fter careful consideration of the special purpose acquisition company market and after having completed an extensive search, OHAA determined it would be unable to deliver and fund a high quality value enhancing transaction to stockholders despite the extension. Therefore, on December 18, 2023, OHAA determined not to further extend the term it has to complete an initial business combination and instead announced its intention to dissolve and liquidate. On December 28, 2023, all OHAA Class A ordinary shares were cancelled with shareholders receiving their respective share redemption amounts. Accordingly, there were no “Redeemable non-controlling interests” or restricted cash balances associated with the publicly held OHAA Class A ordinary shares recorded on the Company’s consolidated balance sheet as of December 31, 2023. OHAA was dissolved in March 2024. Oppenheimer Principal Investments LLC Oppenheimer Principal Investments LLC ("OPI") is a Delaware special purpose "Series" limited liability company formed in December 2020 and designed to retain and reward talented employees of the Company, primarily in connection with the deployment of Company capital into successful private market investments, and also in connection with the Company's receipt of non-cash compensation from investment banking assignments. OPI is designed to promote alignment of Company, client and employee interests as they relate to profitable investment opportunities. This program acts as an incentive for senior employees to identify attractive private investments for the Company and its clients, and as a retention tool for key employees of the Company. OPI treats its members as partners for tax purposes generally and with respect to the separate Series formed to participate in (i) the incentive fees generated by successful client investments in the Company's Private Market Opportunities program, or (ii) principal investments made by the Company or a portion of the gains thereon, either through the outright purchase of an investment or consideration earned in lieu of an investment banking fee or other transaction fee. Employees who become members of a Series receive a "profit interest", as that term is used in Internal Revenue Service (“IRS”) regulations, and receive an allocation of capital appreciation of the investment held by the particular Series that exceeds a threshold amount established for each Series. Participating employees are also subject to vesting and forfeiture requirements for each Series investment. Vested profit interests are accounted for as compensation expense under FASB Topic ASC 710. Additionally, the Company’s policy is to consolidate those entities where it owns the majority voting interests. The Company owns the majority voting interest of OPI through Oppenheimer Alternative Investment Management (“OAIM”), the managing member of OPI and a subsidiary of OAM. Pursuant to the Company’s policy for consolidation, the Company consolidates OPI. Non-controlling Interests Non-controlling interests represent ownership interests in the Sponsor of OHAA. For the six months ended June 30, 2024 and June 30, 2023, the net loss (net of taxes) attributed to noncontrolling interests was $310,000 and $321,000, respectively.
