Meaning
The divisor in ownership equations represents the total outstanding and reserved shares used to determine the price per share in a financing round. Negotiating the capitalization denominator defines how much of the option pool or convertible debt is included before calculating the pre money valuation share price.
Mathematical Role
This mathematical divisor directly controls the final price paid by an incoming investor. By expanding or contracting the included shares, the parties adjust how much dilution is borne by the existing founders. A larger denominator lowers the price per share, which benefits the incoming investor by maximizing their purchased equity for a fixed dollar amount.
Dilution Consequence
Founders experience varying levels of ownership loss depending on the composition of this divisor. When the capitalization denominator is structured to include unallocated option pools, the founders bear the entire dilutive weight of those future grants before the investment occurs. This outcome contrasts sharply with a post money pool construction, where the dilution is shared proportionally among all post investment shareholders.
Contractual Discrepancy
Ambiguity in the term sheet regarding this divisor often leads to last minute disputes before a deal closes. If the definitive documents do not explicitly list which option pools or convertible notes are included in the capitalization denominator, the parties may calculate different purchase prices. Resolving these differences requires a thorough review of the original term sheet and board approvals to establish the mutually agreed calculation, which saves dozens of hours of legal restructuring and prevents the breakdown of the investment transaction.
