Purchases of securities are typically effected through margin accounts maintained with brokers, which may extend margin credit as and when required to open or carry positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules and the brokers’ credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts.
