Mergers, Acquisitions, and D&O: What Happens to Your Policy When the Company Is Sold

A merger or acquisition is one of the biggest events in a company's life, and it's also one of the biggest events in the life of its D&O policy — for reasons that have nothing to do with who's running the company tomorrow and everything to do with who might sue over decisions made yesterday. Because D&O is written on a claims-made basis, a sale can quietly end the window during which old decisions can still be covered, unless specific steps are taken before the deal closes.

Why a Sale Changes the Claims-Made Math

D&O coverage typically responds to claims made during the policy period for conduct on or after the policy's retroactive date, regardless of when that conduct actually occurred. When a company is acquired, the acquiring company often replaces the target's insurance program with its own, which means the target's original D&O policy may simply end. Claims about the pre-acquisition directors' and officers' decisions that surface after that point generally have nowhere to go unless something was done at closing to keep that door open.

Run-Off Coverage: Insuring the Decisions Already Made

The standard fix is typically called run-off or tail coverage — an extended reporting period purchased specifically to let claims about pre-closing conduct still be reported after the original policy ends, often for a period of several years. Run-off coverage doesn't insure anything new; it simply keeps the door open for claims tied to decisions the prior leadership team already made, which is exactly the exposure a claims-made policy would otherwise cut off the moment it's replaced or cancelled.

Why Buyers Often Insist on It

In many transactions, the buyer specifically requires the seller to purchase run-off coverage as a condition of closing, precisely because the buyer doesn't want to inherit uncertain legacy liability for decisions made by a management team it didn't employ. Sellers and the departing directors and officers generally want the same protection for the opposite reason — once the deal closes, they may have little ongoing visibility or control over how claims from their tenure get handled, and a properly funded run-off policy is often their only remaining protection.

How Long a Run-Off Policy Typically Lasts

Run-off periods are commonly negotiated for anywhere from a few years up to six years or more, depending on the deal, the industry, and the statute of limitations considerations that apply to the kinds of claims most likely to arise. Because this is typically a one-time purchase rather than an ongoing renewal, it's worth getting the term and the limit right at the time of the transaction — there's generally no opportunity to extend it later if the original purchase turns out to be too short or too thin.

What Directors and Officers Should Confirm Before Closing

Anyone serving as a director or officer through a sale is generally well served by confirming, in writing, that run-off coverage is being purchased, what retroactive date and limit it carries, and who's paying for it. These terms are typically negotiated as part of the broader transaction documents, and it's considerably harder to add this protection after the deal has already closed and the original policy has lapsed.

Mergers Without a Full Sale

Not every transaction is a clean sale to an outside buyer. Mergers, partial acquisitions, and recapitalizations can all raise similar questions about continuity of D&O coverage, even when the original company technically continues to exist in some form. Any transaction that changes control, combines entities, or restructures ownership is worth treating as a trigger to review the D&O program specifically, rather than assuming the existing policy carries forward unchanged.

A transaction is a busy, deadline-driven process, and D&O continuity is an easy detail to let slide past in the rush to close. An independent agent can help make sure run-off coverage is addressed in the deal terms rather than discovered as a gap after the fact.
