"Mandatory time-based sunset provisions are considered by CFA Institute and other
corporate governance advocates as the most effective safeguard. Under such provisions, super
voting rights would lapse upon an agreed anniversary of the IPO, and the company would
revert to a one-share, one-vote structure. Time-based sunset provisions limit preferential
voting rights to a defined period, and, in turn, relieve minority stakeholders of permanent
exposure to moral hazard."
