Governance Complexities in Firms with Dual Class Shares examines five governance characteristics of DCS firms and does so in the Canadian context where DCS have historically been more prevalent. It examines governance characteristics that are salient in debates about DCS and governance generally. This monograph also takes a broader look at the policy implications of continuing to respect private ordering as a means for regulating public corporations. This full-fledged examination of DCS firms comes at an opportune moment; with controversy and potential regulatory reform on the agenda, the question persists as to how and whether regulators will respond. But before reform occurs, we should know more about DCS, including DCS governance. Section 2 provides background in terms of the DCS structures and the diametrically opposed views about DCS. Section 3 examines theoretical approaches that can be used when analyzing DCS firms including agency theory and principal cost analysis. Section 4 reviews divergences of findings in the empirical literature while Section 5 takes up two case studies of transactions in which DCS firms transformed their respective governance structures. Section 6 examines five governance characteristics against which DCS firms can be examined. Section 7 outlines the methodology and context while Section 8 sets forth data regarding DCS firm governance. The empirical analysis reveals that DCS firms generally do not voluntarily adopt governance provisions over and above existing law. Section 9 focuses on policy alternatives for regulatory reform prior to the conclusion in Section 10.
