Regulatory Requirements [Abstract] |
Regulatory Requirements | Note 6—Regulatory Requirements The Company has a number of consolidated subsidiaries registered as broker-dealers with regulatory agencies in their respective countries. The SEC-regulated subsidiary does not hold funds or securities for, or owe money or securities to clients or carry accounts of or for clients, and as such is exempt from the SEC Customer Protection Rule (Rule 15c3-3). As of June 30, 2026 and December 31, 2025, all regulated subsidiaries had capital in excess of their applicable minimum capital requirements. As a result of the minimum capital requirements and various regulations on these broker-dealers, a portion of the capital of each subsidiary of the Company is restricted and may be unavailable to pay its creditors.
