1. Introduction

An insider list is a register of individuals with access to inside information about a company, primarily to prevent market abuse under:

UK Market Abuse Regulation (UK MAR)

Financial Services and Markets Act 2000 (FSMA)

Companies Act 2006 (for directors’ duties regarding confidential information)

Insider lists are used to control sensitive information, ensuring that directors, employees, and advisors do not engage in insider trading. Proper governance of these lists is critical for legal compliance, shareholder trust, and market integrity.

2. Corporate Governance Issues in Managing Insider Lists

A. Board Oversight

Boards must ensure the establishment, maintenance, and regular update of insider lists.

Oversight responsibilities include:

Assigning accountability for list maintenance

Approving policies on access to inside information

Monitoring compliance and reporting breaches

B. Fiduciary Duties

s.172 Companies Act 2006: Directors must act in the best interest of the company and shareholders, including preventing market abuse.

s.174 Companies Act 2006: Duty of care, skill, and diligence applies to handling confidential or price-sensitive information.

s.175 Companies Act 2006: Directors must avoid conflicts of interest when handling insider information.

C. Risk Management

Insider information mismanagement can lead to:

Regulatory fines from the Financial Conduct Authority (FCA)

Criminal liability for insider dealing

Reputational damage and shareholder litigation

Governance frameworks should include risk assessments, monitoring access, and controls to prevent leakage of sensitive information.

Insider lists must be accurate, complete, and updated.

Reports to regulators may be required if unauthorized disclosures or breaches occur.

E. Conflict-of-Interest Management

Directors, executives, and employees must not trade on inside information.

Governance policies should include mandatory disclosure of trades by insiders and pre-clearance processes.

F. Record Keeping

Insider lists must be retained for at least 5 years under UK MAR.

Lists should include:

Name of the insider

Date access granted and removed

Reason for inclusion

Nature of inside information
