Insider trading prevention: mandatory internal controls for asset managers, including designation, confidentiality, inquiries and whistle blower policy. The Chief Executive Officer or Managing Director of an asset management company must, with trustee approval, implement adequate and effective internal controls to prevent insider trading, including identifying all employees with access to unpublished price sensitive information as Designated Persons, maintaining confidentiality and restrictions on communication, keeping lists of recipients with confidentiality obligations, conducting periodic reviews, and ensuring compliance. Boards and audit committees must oversee and review compliance, and asset management companies must adopt inquiry procedures for leaks, inform the regulator of leaks and inquiry outcomes, maintain a whistle blower policy, and secure cooperation from intermediaries and fiduciaries during inquiries.
