Inspection obligations require brokers to produce records, grant access, and assist inspecting authorities promptly. Regulation 21 requires stock-brokers and their directors, proprietors, partners, officers and employees to produce books, accounts and other documents and furnish statements and information relating to securities transactions to the inspecting authority within required timeframes; to grant reasonable access to premises and facilities for examination of books, records, documents and computer data; to provide copies of relevant materials; and to permit examination or recording of statements, giving all reasonable assistance in connection with the inspection.
