Mandatory Disclosure of Blockholders and Related Party Transactions: Stringent Versus Flexible Rules

Investor confidence in financial markets depends in large part on the existence of an accurate disclosure and reporting regime that provides transparency in the beneficial ownership and control structures of publicly listed companies. Today, a common post-financial crisis regulatory reform theme is to tighten the disclosure and reporting rules that apply to large blockholders. We examine the implications of this trend, analyzing whether detailed, stringent and mandatory reporting rules could have a counterproductive effect on the financial markets. A central idea of this paper is the evolution of a well-balanced regime that is flexible and proportional and allows for a case-by-case determination of a beneficial owner. In the current era of information-based technology, the most obvious challenge for regulators is to design a legal framework that is adaptable to technological change and its impact on financial instruments.
