On June 13, 2023, FINRA approved the broker-dealer's continuing membership application to expand its business to routing of options orders on behalf of the Exchange. As of December 31, 2023, the broker-dealer has not begun routing options orders. The company is a registered broker-dealer regulated by the Securities and Exchange Commission ("SEC"), FINRA, other self-regulatory organizations ("SROs") of which it is a member, and other federal and state agencies. FINRA is the Company's designated examining authority. The Company is subject to the SEC's net capital rule, which specifies minimum net capital levels for registered broker-dealers and is designed to enforce minimum standards for the financial condition and liquidity of broker-dealers. The Company does not hold customer funds or safekeep customer securities and it clears all transactions on a fully-disclosed basis through its clearing firm. #### **2.
