Trustees must ensure charged company assets together with deposit insurance adequately cover repayment of secured deposits and accrued interest; verify that solicitation materials conform to the deposit scheme, trust deed and statutory rules; prevent and remedy breaches of trust deed covenants; supervise creation and enforcement of security and insurance; call depositor meetings as required; and take necessary actions to protect depositors and resolve grievances.
