Stock brokers must maintain specified books of account, notify their location, submit audited accounts, and keep extra underwriting records. Every stock broker must maintain, physically or electronically, specified books of account and records (including transaction register, client and general ledgers, cash and bank books, securities registers, contract notes, margin ledgers and client account opening forms). Brokers in the Execution Only Platform must maintain the same records. Brokers must inform the recognised stock exchange of the location of records and provide audited balance sheet and profit and loss account within six months or as specified. Brokers acting as underwriters must keep additional underwriting records such as agreements, subscription totals, corporate financial statements and auditors' reports or detailed receipts, expenditures and asset-liability statements.
