How Sunset Clauses Can Soften the Negative Effects of Tenure-Based Shareholder Voting

By Maria Lucia Passador August 1, 2025 by renholding

In a new paper, I examine the potential of sunset clauses – legal provisions that automatically phase out enhanced voting rights over time or upon certain events – to mitigate the imbalances and entrenchment risks associated with tenure-based voting structures, …

Do Dual-Class Structures Help Stock Markets Attract Listings?

By Fa Chen October 30, 2023 by renholding

Financial globalization has allowed issuers more freedom to shop among jurisdictions and thus intensified stock market competition. Against this backdrop, the Hong Kong, Singapore, China, and UK stock markets have accepted the dual-class share structure (DCSS). While empirical legal studies …

Does “Wedge” Size in Dual-Class Firms Matter?

By Rimona Palas, Dov Solomon, Dalit Gafni and Ido Baum October 19, 2023 by renholding

The structure of dual-class stock, where one class of shares confers more votes per share than the other, creates a gap (“wedge”) between voting rights and cash flow rights that allows insiders to raise capital without relinquishing effective control of …

Why Do Companies Going Public Choose Controversial Governance Structures, and Why Do Investors Let Them?

By Laura Field and Michelle Lowry June 21, 2022 by renholding

Over the past three decades, there has been increasing concern about how corporate governance structures such as classified boards and dual class stock entrench managers, reduce director effectiveness, and reduce firm value. Likely as a result, mature firms have increasingly …

A Lawyer’s Guide to Empirical Corporate Governance

By Ofer Eldar May 27, 2022 by renholding

Debates about corporate governance ultimately rest on empirical studies that evaluate whether a particular type of governance enhances shareholder value. In recent years, lawyers have increasingly engaged with these studies, by either criticizing or praising them, and given them greater …

Public Corporations’ Bylaws as Standard Form Contracts

By Eli Bukspan May 13, 2022 by renholding

Vast corporate growth over more than a century has weakened shareholder voting rights, as highlighted by, among other things, the rise of dual-voting stock IPOs. The extent of that growth, and the lack of people’s power to negotiate with …

Initial Public Offerings and Optimal Corporate Governance

By Albert H. Choi March 9, 2022 by renholding

Do companies adopt optimal governance arrangements when they go public?  This question has been a hotly debated topic in corporate law and governance and one that I examine in a recent paper.

At the time of an initial public offering …

Private Ordering in Social Enterprise: New Corporate Structures for Mission Commitment

By Naveen Thomas May 10, 2021 by renholding

Just over 10 years ago, benefit corporations emerged as legal entities intended to permit for-profit social enterprises to pursue public-interest missions. While increasingly popular among states and businesses, these new entities have received unending criticism from commentators on all sides. …

By Dhruv Aggarwal, Ofer Eldar, Yael V. Hochberg and Lubomir P. Litov April 21, 2021 by renholding

Discretionary Decision-Making and the S&P 500 Index

By Bernard S. Sharfman and Vincent Deluard March 30, 2021 by renholding

Discretion is an integral part of how indices, including stock market indices, are constituted, according to professors Rauterberg and Verstein and Robertson (here and here), and the S&P 500 index is no exception.

The S&P 500 is a …

The Myth of Dual Class Shares: Lessons from Asia

By Min Yan February 16, 2021 by renholding

Companies with dual class shares have, as the term suggests, two (or more) classes of common stock. One class gives its holders voting power proportionate to their equity shareholdings. The other offers a group of shareholders, normally corporate insiders, weighted …

What to Do About Poor Corporate Governance at Unicorns

By Amy Deen Westbrook January 18, 2021 by renholding

Why are large private companies often characterized by poor corporate governance?  WeWork provides a recent high-profile example.  For reasons that now seem implausible, WeWork attracted billions of investment dollars.  Perhaps it was the company’s “vision” or the sheer personality of …

By Anat Alon-Beck, Robert Rapp and John Livingstone December 24, 2020 by renholding

More Than Meets the Eye: Reassessing the Empirical Evidence on U.S. Dual-Class Stock

By Bobby V. Reddy May 12, 2020 by renholding

Since Google (now Alphabet) issued dual-class stock at its IPO in 2004, the subject has been vigorously debated throughout the world.  Unlike firms whose shares all have equal voting rights (“one-share, one-vote firms”), companies with dual-class stock allow a founder …

Designing Dual Class Sunsets: The Case for a Transfer-Centered Approach

By Marc Moore December 19, 2019 by renholding

By David J. Berger March 29, 2019 by renholding

Dual Class Companies Should Adopt a Coattail Provision

By Yvan Allaire January 18, 2019 by renholding

I would like to make two points in response to Professor Coffee’s piece on dual class common stock.

First, American dual class companies should be obliged to include a “coattail” provision, as is the case in Canada. This provision, imposed …

Against Mandatory Sunset for Dual Class Firms

By Zohar Goshen January 2, 2019 by renholding
