Meaning
Equity adjustment occurring during new share issuance. Owners experience common equity dilution when a company issues additional shares to investors or employees. This event reduces the proportional ownership and voting weight of the existing ordinary shareholders.
The calculation compares the pre-issuance share count against the post-issuance total to determine the new percentage held by each party. It is a standard feature of growth where multiple rounds of funding are required to scale the business.
Allocation Effect
Issuing new shares creates a larger denominator in the ownership equation. While common equity dilution reduces the percentage owned, it often occurs alongside an increase in the total value of the company. Founders accept this trade to gain the resources needed to build a larger enterprise.
The process is managed through legal documents that specify the number of shares authorized for issuance.
Percentage Decay
Tracking the reduction in ownership requires a detailed understanding of the fully diluted record. Each round of financing introduces common equity dilution that can be calculated using the price per share and the investment amount. This impact is felt most by early holders who do not purchase more shares in subsequent rounds.
A clear record of these changes is necessary for accurate corporate governance.
Issuance Constraint
Shareholder agreements often include protections to limit the severity of these events. Antidilution clauses provide a way for existing owners to mitigate common equity dilution by purchasing more shares.
