Change-in-Control Trigger (Single vs. Double)

A change-in-control trigger is the provision in an executive’s employment agreement or award agreement that defines when severance pay and accelerated vesting become payable around a merger, acquisition, or similar transaction. The trigger is not the benefit itself; it is the condition that turns a contingent promise into an obligation. Two designs dominate practice: a single trigger, satisfied by the transaction closing, and a double trigger, which requires the transaction plus a qualifying termination of the executive’s employment.

Under a single trigger, the change in control alone activates the benefit. The executive can be offered a comparable role in the combined company and keep working, and the severance or vesting still occurs because the deal itself satisfied the condition. That is why single-trigger designs draw more scrutiny from proxy advisers and investors: the payment is not tied to any loss of employment, and the executive may collect it while continuing to hold the same job.

Under a double trigger, the deal closing is only the first condition. The second is a qualifying termination, most often an involuntary termination without cause or a resignation for good reason, occurring within a defined window after the transaction. Good reason typically covers a material reduction in duties, pay, or location, which lets an executive whose role has effectively been dismantled by the integration treat the departure as qualifying.

The definitions behind the labels do more work than the labels themselves. What counts as a change in control — a merger, a sale of substantially all assets, or a change in a majority of the board — can be drafted broadly or narrowly, and a transaction a reader would casually call a takeover may fail to meet a narrowly written definition. The same is true of cause and good reason: a narrowly drawn definition of cause makes it more likely that a termination falls outside it and therefore counts as without cause.

Cash severance and equity acceleration carry their own triggers in most agreements, and the two do not have to match. A company can require a double trigger for cash severance while allowing unvested equity to accelerate on the single trigger of the closing, or the reverse. Reading a proxy’s potential-payments disclosure therefore means reading each benefit line on its own terms rather than assuming one trigger governs the whole package.

The termination window that completes a double trigger is itself a negotiated term. It may run from the signing of the deal, from the closing, or for a stated period after closing, and a departure outside it leaves the executive with only whatever ordinary severance terms the agreement provides, if any. The window’s length and its starting point are as consequential as the presence of a double trigger at all.

Double-trigger structures became the governance norm because they align payment with an actual separation rather than with a corporate event the executive did not experience as a job loss. Where a single trigger remains, it is most often attached to awards granted years earlier or to arrangements negotiated at a company’s initial public offering, and it is a frequent subject of shareholder proposals and of proxy adviser recommendations against a company’s say-on-pay vote.

Trigger design also decides whether a payment becomes a parachute payment under Internal Revenue Code Section 280G. Only payments contingent on a change in control are counted toward the threshold that applies, so a benefit that a double trigger leaves unvested, because no qualifying termination occurred, never enters the calculation at all.

Leidos structures its change-in-control severance as a double trigger: a 1.5x payout to its CFO requires both a change in control and a qualifying termination, not the change in control alone.
