A participating liquidation preference is an investor protection whereby preferred shareholders receive their liquidation preference amount first, and then also participate pro rata in remaining proceeds alongside ordinary shareholders — effectively double-dipping. Unlike the non-participating variant, investors receive both components without having to choose. This structure is more favourable to investors but more dilutive for founders in higher-value exit scenarios. In fundraising negotiations, participating preferences are increasingly resisted by founders in competitive term sheet environments.

‍

Example: an investor holds 25% with a CHF 4.0 million participating preference. At a CHF 20.0 million exit: preference = CHF 4.0 million + participation = 25% × (20.0 - 4.0) = CHF 4.0 + 4.0 = CHF 8.0 million — 40% of total proceeds for 25% of capital. Founders receive CHF 12.0 million (60%) versus CHF 15.0 million they would receive under a non-participating preference converted at the same exit — a CHF 3.0 million difference highlighting the economic cost of the participating structure.
