Commitments and Contingencies
 
Retail customer transactions are cleared, on a fully disclosed basis, through two clearing brokers, one of which is a related party. If customers do not fulfill their contractual obligations, the clearing broker may charge MSCO for any loss incurred in connection with the purchase or sale of securities at prevailing market prices to satisfy the customers’ obligations. MSCO regularly monitors the activity in its customer accounts for compliance with its margin requirement. MSCO is exposed to the risk of loss on unsettled customer transactions if customers fail to fulfill their contractual obligations. There were no material losses for unsettled customer transactions for the nine months ended September 30, 2018 and September 30, 2017.
