The process of monitoring trading by the employees of broker-dealers has several components. Employees of broker-dealers should receive permission from their employers to open a securities account at another firm and, once an away account is opened, should notify both their employer of the account and the firm that opened the account of their employment status and employer. The firm that opened the account must make arrangements to send trade information to the individual's employer as well as the employee. The employing firm generally must obtain the trade information and review the employee's trades.
