﻿ Market data fees are charged to customers for market data services they subscribe to and are largely offset by the related cost s paid to obtain market data from third party vendors. Account activity fees are charged to customers that do not generate the minimum monthly commission. The fee is the difference between the minimum required commission and the actual commissions generated. Risk exposure fees are earned from a small minority of customer accounts carrying positions with market risk that exceeds defined thresholds. Payments for order flow are earned from various options exchanges based upon options trading volume originated by the Operating Companies. Gains on financial instruments, at fair value and other investments, net include (1) realized and unrealized gains and losses on financial instruments that (a) are held for purposes other than the Company’s market making operations, (b) are subject to restrictions, or (c) are accounted for under the equity method and (2) dividends on investments accounted for under cost method.
