Vesting, Cliffs, Settlement, and Double Triggers

A single “vesting date” field cannot represent every equity award. Service vesting, exercise, settlement and sale may happen years apart.

Equity portals often present a timeline that looks simple: grant, monthly or quarterly vest, expiration. In reality, several clocks can run at once. A planning model must label each clock rather than treating every date as the day value becomes cash.

Grant date

The grant date identifies when the award was issued and can start statutory periods or service-allocation periods. It also anchors the original terms. Save the grant notice and plan document rather than relying on a portal summary.

Cliff and tranche vesting

A cliff requires a minimum service period before the first tranche vests. After the cliff, awards may vest monthly, quarterly or on another schedule. Performance awards can depend on metrics in addition to time. Unvested awards can be forfeited when employment ends, subject to the plan.

Exercise and expiration

For options, vesting normally makes the option exercisable; it does not acquire the stock. The employee must exercise before the contractual expiration and any post-employment deadline. Exercise creates a share lot and can trigger NSO wage income or ISO AMT.

Settlement

An RSU settles when the company delivers shares or cash. At a public company, vest and settlement are often close. A private double-trigger award can require both service vesting and a qualifying corporate or liquidity event. Service-vested units can therefore remain unsettled.

Sale and holding period

Sale is a separate transaction. For stock acquired from options, grant, exercise and sale dates can all matter. For public RSUs, later price movement after settlement can create capital gain or loss. For private shares, transfer restrictions can delay sale indefinitely.

Build a tranche-level timeline

1. Create every vesting tranche with date and quantity.
2. Add exercise eligibility, expiration and post-employment deadline for options.
3. Add second-trigger, settlement and outside deadline for private RSUs.
4. Attach actual exercise, settlement, sale and tax evidence when they occur.
