Design Dual-Class Share Governance

Design a dual-class share structure's governance safeguards — including a time- or event-based sunset provision converting to a single class — rather than adopting a perpetual dual-class structure with no mechanism for eventual alignment between voting control and economic ownership.

Why This Is Best Practice

Adopted by: The Council of Institutional Investors has published a specific model policy recommending dual-class structures include a sunset provision (commonly 7 years post-IPO, or tied to a founder's departure or a specified ownership decline), and both NYSE and Nasdaq permit dual-class listings while an increasing number of newly public companies with dual-class structures have voluntarily incorporated sunset provisions in response to sustained institutional investor pressure. Impact: Dual-class companies without a sunset provision are documented to face measurably lower institutional investor participation, exclusion from certain major stock indices (which have adopted policies limiting or excluding perpetual dual-class companies), and sustained shareholder proposal pressure to add a sunset — while companies with a disclosed, reasonable sunset timeline face substantially less of this friction. Why best: A dual-class structure serves a genuine purpose immediately post-IPO — protecting a founder's long-term strategic vision from short-term market pressure during a critical early period — but that justification weakens over time as the founder's ownership stake typically declines through equity sales, dilution, and succession, while their voting control (under a perpetual structure) does not; a sunset provision is what actually ties the structure's duration to its original justification rather than allowing control to persist indefinitely regardless of whether the original rationale still holds.

Steps

Step 1: Define the structure's specific governance rationale at adoption

Document the specific governance rationale for adopting a dual-class structure at IPO — protecting long-term strategic execution from short-term market pressure during a defined critical period — as the basis against which a sunset timeline should be calibrated.

Step 2: Set a time-based sunset provision tied to a defensible horizon

Set a specific time-based sunset provision (commonly 5-10 years post-IPO) after which the dual-class structure automatically converts to a single class with equal voting rights, providing a clear, disclosed timeline institutional investors and proxy advisory firms can evaluate in advance.

Step 3: Consider event-based triggers alongside or instead of a pure time-based sunset

Consider supplementing or replacing a purely time-based sunset with event-based triggers — the founder's death, incapacity, departure from an active operating role, or their ownership stake declining below a specified threshold — since these events can more directly track whether the structure's original justification (founder-specific strategic vision) still applies.

Step 4: Disclose the sunset provision clearly in governance documents

Disclose the sunset provision's specific terms clearly in the company's governing documents and public disclosures, since an undisclosed or ambiguous sunset provides little of the institutional investor confidence a clear, binding, disclosed provision is specifically designed to provide.

Step 5: Avoid provisions allowing the sunset to be extended unilaterally

Avoid structuring the sunset provision so that it can be extended or waived unilaterally by the controlling shareholder or board without a genuine independent or shareholder check — a sunset that can simply be extended at the controller's discretion provides materially weaker protection than a binding, hard-to-modify provision.

Rules

• Document the specific governance rationale for the dual-class structure at adoption, as the basis for calibrating an appropriate sunset timeline.
• Include a specific, disclosed time-based sunset provision, commonly in the 5-10 year range post-IPO.
• Consider event-based triggers (founder departure, ownership decline) alongside or instead of a purely time-based sunset.
• Avoid structuring the sunset so it can be unilaterally extended or waived by the controlling shareholder without an independent check.

Examples

Sunset provision aligning control with its original justification: A founder-controlled company adopts a dual-class structure at IPO with a disclosed 7-year sunset, converting automatically to a single class regardless of the founder's continued involvement. This clear, binding timeline provides institutional investors confidence the structure won't persist indefinitely beyond its original founder-protection rationale.

Perpetual structure facing sustained pressure (illustrative caution): A different company adopts a dual-class structure with no sunset provision. Several years later, after the founder's ownership stake has declined substantially through sales and dilution while voting control remains unchanged, the company faces a shareholder proposal and exclusion from a major stock index specifically due to the absence of any sunset mechanism.

Common Mistakes

• Adopting a perpetual dual-class structure with no sunset provision at all — this is documented to draw sustained institutional investor pressure and potential index exclusion.
• Setting a sunset timeline disconnected from the structure's original stated rationale — a sunset should genuinely track the period during which the original justification (founder-specific strategic protection) plausibly applies.
• Structuring the sunset so the controlling shareholder can unilaterally extend or waive it — this undermines the credibility of the commitment the sunset is meant to represent.
• Failing to disclose the sunset provision's specific terms clearly — an ambiguous or buried disclosure provides little of the investor confidence a clear, prominent disclosure is designed to provide.

When NOT to Use

• For a company not considering or currently using a dual-class structure — this practice specifically addresses governance design for companies with or considering unequal voting rights between share classes.
• For a jurisdiction or exchange that doesn't permit dual-class listings, or for a company whose specific circumstances (e.g., certain regulated industries) impose different applicable requirements.
• As a substitute for the company's broader corporate governance framework — dual-class structure design addresses this specific voting-rights question; see design-corporate-governance-structure for the broader governance framework.
