INFORMATION ASYMMETRY AND SHAREHOLDER REMEDIES IN CONTEMPORARY COMPANY LAW

Abstract

The modern corporation is based on a key division between the owners of capital and those who control it. Shareholders provide capital and take on the residual risk; Directors and managers have better knowledge of the activities, finances and prospects of the company. ‘Information asymmetry’ is a structural imbalance in economics that allows for opportunities to exploit others, engage in self-dealing and diminish shareholder value. The article looks at the nature of information asymmetry in corporate governance and challenges its effectiveness in mitigating its effects through shareholder remedies under modern company law. The article builds on the foundational economic concepts of adverse selection and signaling, the agency-cost theory, and comparative statutory and case law from Nigeria, the United Kingdom, and the United States as it chronicles the development of disclosure requirements, insider-dealing bans and corporate governance codes to reduce the information gap between controllers and outsiders. It then examines the detailed doctrines of the key remedies available for oppression, mismanagement or fraud where the relationship becomes unfairly prejudicial: the derivative action, the statutory remedy for unfairly prejudicial and oppressive conduct, the statutory right of access or inspection of company information, appraisal and buy-out rights, and the equitable remedy of winding up on the just and equitable ground. The rule in Foss v. Harbottle and its exceptions are reviewed, as well as the landmark decisions of the courts on oppression and unfair prejudice, and the reforms in the Companies and Allied Matters Act 2020, Investments and Securities Act 2025 and Companies Act 2006. The article suggests that although current statutory reform has made minority shareholder remedies more liberal, structural, procedural and institutional barriers remain that have a dampening effect on their actual power, especially when minority ownership is concentrated and institutional enforcement is weak, such as in the United States. It also argues that remedies are not sufficient to eliminate information asymmetry; they need to be backed up by a strong ex ante disclosure framework and empowered regulatory oversight, alongside transparency that is enabled through technology. The article concludes by suggesting a multi-layered agenda for reform, which includes mandatory disclosure, cost-shifting litigation funding provisions, qualified judicial capacity and regulation-led enforcement, to make shareholder remedies more than just theoretical in modern corporate law.
