Equity exercise windows

By Offer Unpacked · Updated

An exercise window is the time available to buy shares under an option after a triggering event. Record the deadline and cash required separately from vesting and any headline equity value.

Vesting and exercise answer different questions

Vesting tells you how much of an award has been earned under its schedule. Exercise is the step of purchasing shares under an option. A vested option is not the same as cash in your account, and this checklist should not be applied unchanged to restricted stock units or other awards.

Request the plan, grant agreement, exercise price, vested option count and the rule for each departure scenario. Resignation, dismissal, disability and death may have different deadlines. Ask whether the clock starts on your last working day, the legal termination date or another defined event.

Separate the purchase cost from the tax question

Calculate option count multiplied by exercise price to identify the purchase price before fees or tax. Ask whether a cashless exercise is available and whether shares can actually be sold. A company valuation does not guarantee an available buyer.

U.S. tax treatment differs between option types and can depend on timing. IRS Topic 427 describes those categories. Have an adviser check the particular award and relevant countries before treating an extended exercise window as an unqualified improvement.

Ask for the operational details before accepting

Find out who sends the departure notice, how you submit exercise instructions and how payment is accepted. A promise to discuss an extension later is not a confirmed change to the grant. Ask which document would record the extension and who must approve it.

Illustrative example

A fictional grant has 4,000 vested options at an exercise price of $3 and a 30-day departure window. Buying all 4,000 would require $12,000 before any tax or fees.

The useful question is whether you can make an informed $12,000 decision in that window. Neither the option count nor a company valuation tells you what you can sell the shares for.

What to look for

  • A short post-termination exercise deadline
  • No current exercise-price or tax information
  • Plan documents that override the offer letter

Questions to ask

  1. What is the exact post-termination window?
  2. May I review the plan and grant documents before accepting?
