Meaning
Contractual adjustment provides existing equity holders with additional shares if subsequent funding occurs at a lower valuation than previous rounds. Deployment of share conversion ratchets preserves the percentage interest of early stage investors against sudden market declines. This mechanism resides within the articles of association or the shareholders agreement of a venture.
It functions by recalibrating the conversion ratio at which preferred units become common units.
Economic Dilution
Mechanism activates only upon the confirmation of a qualified downward event. With share conversion ratchets, the number of extra units issued corresponds to the gap between the initial price and the current price. This ensures the senior holders maintain the same financial position they had at the higher watermark.
Anti-Dilution Logic
Preference levels dictate whether the adjustment is based on a single price point or a weighted average. Narrow share conversion ratchets only provide protection for simple gaps, while broad average versions look at the entire capital base. Founders often negotiate for broader averages to limit the total number of new units handed out.
Exit Priority
Settlement occurs before generic distributions are shared among the wider group. Final calculations for share conversion ratchets occur at the moment of an exit if no prior conversions took place. It effectively moves value from junior classes into senior protected classes right before the cash changes hands.
