Asset Management Companies (AMCs) are permitted to charge operating expenses for managing or running a mutual fund business. These expenses include sales and marketing expenses, administrative expenses, transaction costs, investment management fees, registrar fees, and custodian fees amongst others, also known as ‘Expense Ratio’. In short, the Total Expense Ratio (TER), or the fees charged by AMCs to manage a scheme, is expressed as a percentage of the assets managed by the fund manager.
