Meaning
Reserved shares within a company capitalization table provide the mechanism for granting ownership interests to workers without requiring immediate cash outlays. These employee stock pools allow a person who has founded a business to align the interests of the team with the long term value of the firm. The size of the reserve usually ranges from ten to twenty percent of the total equity.
It acts to formalize the transition from a founder led project to an institutionally owned entity.
Dilution Management
Creating the reserve often happens during a funding round to ensure that new shares come from the existing ownership rather than the investors. This move reduces the percentage held by the founder. It is a cost in ownership that the person pays to facilitate future growth.
Recruitment Power
Attracting high level talent requires the ability to offer a stake in the success of the venture. Without a dedicated reserve, a founder would have to seek board approval for every individual hire. The stock repurchase option and other vesting terms often govern how these shares return to the pool if a worker leaves.
Allocation Constraint
The depletion of the reserve requires a person in the manager seat to be selective about who receives equity. Every grant reduces the remaining capacity to hire or promote. Once the pool is empty, the company must undergo a new authorization process to increase it.
