Books, Records, and Customer Statements

Learn how Series 4 tests confirmations, statements, complaint records, options communications retention, and other required records.

The options principal also has to know what the firm must preserve. Series 4 tests options-specific recordkeeping, customer confirmations and statements, customer-mail handling, complaint records, options-communications retention, SIPC information, and daily margin records. The underlying theme is simple: if the firm cannot evidence the account’s activity and the firm’s supervision, then the controls are not reliable.
