Why Acceleration Matters
In an acquisition, buyers often cancel unvested options. Without an acceleration clause, being fired post-acquisition means losing years of unvested equity. Acceleration provisions are your protection — and most employees don't know whether they have them.
Single-Trigger Acceleration
All unvested options vest immediately upon one trigger — typically a change of control (acquisition, merger). Excellent for employees. Buyers dislike it: it creates immediate dilution and eliminates retention incentive. Single-trigger is rare in India outside of very senior or co-founder-level hires.
Double-Trigger Acceleration
Requires two events: (1) a change of control AND (2) termination without cause — or constructive dismissal — within 12–18 months of the change of control. This is the market standard. It protects you if you're pushed out post-acquisition while preserving retention incentives if you choose to stay.
Partial Acceleration
A middle ground: 50% of unvested options accelerate on the double trigger, the rest continue normally. Common for Director and VP-level employees at growth-stage companies.
What to Negotiate
When joining a company, ask: Does the ESOP scheme include acceleration? What triggers it? Does "cause" follow the scheme or employment contract? Is there a "good reason" provision for constructive dismissal? These questions reveal how seriously the company treats employee equity — and they're reasonable to ask at offer stage.
Tax Note
Acceleration doesn't change the tax timing. The perquisite tax is triggered at the point of exercise, not at the point of accelerated vesting. Plan accordingly.
