Regulatory fee definitions establish who pays and how terms like financial year, quarter, and recognised stock exchange apply. Regulation 2 defines key terms for levy and administration of the regulatory fee: Act as the enabling securities statute, Board as the securities regulator, and company by Companies Act meaning. It fixes temporal markers-financial year commencing 1 April and quarter as three month periods beginning 1 April, 1 July, 1 October and 1 January. It defines recognised stock exchange as an exchange recognised under the securities contracts statute and states that undefined terms carry meanings from the enabling Acts, related statutes, rules, regulations or schemes and their statutory modifications.
