Option Pool

How to Create an Option Pool

Creating an option pool means reserving a block of unissued shares, adopting a written plan, and getting board and often shareholder approval before any grants are made.

Core steps
Reserve shares, adopt plan, get approvals
Common plan types (UK)
EMI, CSOP, unapproved options
Common plan types (EU)
Local qualifying plans or unapproved options
Approvals to adopt a plan
Board resolution, often shareholder resolution too

Legal process for share reservation

  • Decide the pool size as a percentage of fully diluted shares, based on a hiring plan.
  • Choose or draft an option plan document that sets out eligibility, vesting defaults, exercise mechanics and leaver provisions.
  • Pass a board resolution to adopt the plan and reserve the agreed number of shares for it.
  • Where required, pass a shareholder resolution authorising the directors to issue shares on exercise, since new shares dilute existing holders.
  • Update the cap table to show the pool as reserved but unallocated, separate from shares actually granted.

Selection of tax efficient equity schemes

In the UK, many startups use an EMI scheme because it offers favourable tax treatment for employees and is well understood by investors, subject to company and employee eligibility limits. Where EMI is not available, companies use unapproved options or a CSOP. In continental Europe, plan structures vary by country: some jurisdictions have qualifying regimes with tax advantages, while others rely on standard option agreements without a special tax status, a decision usually made alongside increasing a pool planning for future rounds.

This is general information, not legal or tax advice. Get local advice before choosing a plan structure, since eligibility rules and tax treatment differ by country and change over time, particularly for stock options granted to employees in multiple countries.

Setting up a pool for the first time

Do I need a lawyer to create an option pool?
It is strongly recommended. Plan rules and grant documents have legal and tax consequences, and mistakes are expensive to unwind.
Can the pool sit unused for a while?
Yes. Reserving shares does not require you to grant them immediately. Many companies reserve a pool at a fundraising round and grant options gradually as they hire.
Does creating a pool dilute existing shareholders immediately?
Reserving shares for the pool dilutes fully diluted ownership on paper, but actual issued share dilution only happens when options are granted and exercised.
