fully disclosed clearing agreement, the majority of its securities inventories and all of its customer activities are held by or cleared through Pershing LLC ("Pershing"). The Company has also established an arrangement to obtain financing from Pershing related to the majority of its trading activities, as well as an overnight financing arrangement with a broker dealer related to its convertible securities inventories. Financing under these arrangements is secured primarily by securities, and collateral limitations could reduce the amount of funding available under these arrangements. The funding is at their discretion and could be denied. The Company's clearing arrangement activities are recorded net from trading activity. The Company's fully disclosed clearing agreement includes a covenant requiring Piper Sandler to maintain excess net capital of $120 million.
