Regulatory fee rates require tiered annual payments by stock exchanges and quarterly remittances tied to listing fees within prescribed timelines. Regulation 4 establishes a tiered regulatory fee payable by recognised stock exchanges based on annual turnover, with specified fees due within thirty days of the financial year end and a marginal charge for turnover above the highest band; it defines annual turnover as the aggregate value of transactions on the exchange and includes a transitional reduced annual fee for regional commodity derivatives exchanges.
