This chapter examines the impact of insider regulation on the board-shareholder dialogue. It offers a comparative analysis, revealing that EU and UK laws are more restrictive than those in the US. Drawing from this analysis, the paper raises the question of whether the EU should introduce a safe harbour rule to facilitate shareholder engagement through private disclosure of inside information. While shareholder engagement is considered beneficial for corporate governance and long-term firm value, the paper questions the necessity of selectively disclosing inside information to investors. It argues that mandating greater transparency in the board-shareholder dialogue is preferable, ensuring all shareholders have equal access to information. The feasibility and practicality of a safe harbour rule are doubted due to associated costs and challenges. In conclusion, the chapter rejects proposals to enact such rules, citing limited benefits and substantial costs.
