Broker-Dealer [Abstract] |
Regulatory Capital Requirements | 3. Regulatory Capital Requirements Certain of the Company’s U.S. subsidiaries are registered as broker-dealers and are subject to the applicable rules and regulations of the SEC, the Financial Industry Regulatory Authority (“FINRA”) and the Commodity Futures Trading Commission (“CFTC”). These rules contain minimum net capital requirements, as defined in the applicable regulations. Certain of the Company’s foreign subsidiaries are regulated by the Financial Conduct Authority (“FCA”) in the United Kingdom (“U.K.”) or other foreign regulators and must maintain financial resources, as defined in the applicable regulations, in excess of the applicable financial resources requirement. As of September 30, 2025, each of the Company’s subsidiaries that are subject to these regulations had net capital or financial resources in excess of their minimum requirements. As of September 30, 2025, the Company’s subsidiaries maintained aggregate net capital and financial resources that were $603.4 million in excess of the required levels of $43.3 million. One of the Company’s U.S. broker-dealer subsidiaries is required to segregate funds in a special reserve bank account for the benefit of customers pursuant to Rule 15c3-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As of September 30, 2025, this U.S. broker-dealer subsidiary had a balance of $48.4 million in its special reserve bank account. This U.S. broker-dealer subsidiary also maintained net capital that was $327.8 million in excess of the required level of $3.8 million. Each of the Company’s U.S. and foreign regulated subsidiaries are subject to local regulations which generally limit, or require the prior notification to or approval from such regulated entity’s principal regulator before, the repayment of borrowings from the Company or affiliates, paying cash dividends, making loans to the Company or affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources.
