Financial Instruments With Off-balance-sheet Risk And Concentrations Of Credit Risk |
Financial Instruments with Off-Balance Sheet Risk | 16. Financial Instruments with Off-Balance Sheet Risk The Company enters into various transactions to meet the needs of customers, conduct trading activities, and manage market risks and is, therefore, subject to varying degrees of market and credit risk. In the normal course of business, the Company's customer activities involve the execution, settlement, and financing of various customer securities transactions. These activities may expose the Company to off-balance sheet risk in the event the customer or other broker is unable to fulfill its contracted obligations and the Company has to purchase or sell the financial instrument underlying the contract at a loss. The Company's customer securities activities are transacted on either a cash or margin basis. In margin transactions, the Company extends credit to its customers, subject to various regulatory and internal margin requirements, collateralized by cash and securities in the customers' accounts. In connection with these activities, the Company executes and clears customer transactions involving the sale of securities not yet purchased, substantially all of which are transacted on a margin basis subject to individual exchange regulations. Such transactions may expose the Company to off-balance sheet risk in the event margin requirements are not sufficient to fully cover losses that customers may incur. In the event the customer fails to satisfy obligations, the Company may be required to purchase or sell financial instruments at prevailing market prices to fulfill the customer's obligations. The Company seeks to control the risks associated with its customer activities by requiring customers to maintain margin collateral in compliance with various regulatory and internal guidelines. The Company monitors required margin levels daily and pursuant to such guidelines, requires customers to deposit additional collateral or to reduce positions when necessary. The Company's customer financing and securities settlement activities may require the Company to pledge customer securities as collateral in support of various secured financing sources such as bank loans and securities loaned. In the event the counterparty is unable to meet its contractual obligation to return customer securities pledged as collateral, the Company may be exposed to the risk of acquiring the securities at prevailing market prices in order to satisfy its customer obligations. The Company controls this risk by monitoring the market value of securities pledged on a daily basis and by requiring adjustments of collateral levels in the event of excess market exposure. In addition, the Company establishes credit limits for such activities and monitors compliance on a daily basis.
