Why tail needs to be part of the deal, not an afterthought
Most agency E&O is written on a claims-made basis, which means the policy responds to claims first reported during the policy period, not to the date the work was performed or services were provided. When ownership changes and the policy ends, the work you did last year (and a decade before that) is still out there. The coverage that was sitting on top of it may not carry forward.
Tail coverage, formerly known as an extended reporting period, extends the window during which a claim about prior work can be reported to the carrier. A few reasons it earns a place within the deal terms: it keeps your prior acts covered under the policy that was actually in force when the work was done; it removes the assumption that the buyer's policy will pick up your old work (it generally will not, because their policy is written for their entity); and it puts a known cost on a known risk, instead of leaving you exposed to a claim that surfaces two years after you have moved on.
A claim scenario worth sitting with
Consider an agent who sells her agency effective January 1, but her E&O policy's expiration date is the day before. No tail is purchased because the buyer assured her his policy would handle anything that came up. In March, a former client files a claim alleging she failed to recommend flood coverage on a property bound two years earlier. The buyer's carrier denies the claim because the work predates the buyer's policy and the seller is not a named insured. Her own carrier denies it because the policy expired and no ERP was elected. The exposure sits on her personally. This happens more often than you'd think. It is the predictable result of treating tail as something to figure out after closing rather than before.
Questions worth raising with whoever placed your policy
- What does my policy say about ERP, what length options exist, and how long after termination do I have to elect it?
- If the deal is a stock sale, will the carrier consent to continuation? If it is an asset sale, what does the wind-down look like?
- How should the tail be referenced in the purchase agreement so the document and the policy say the same thing?
Tail coverage is one of those conversations that costs almost nothing to have early and a lot to have late.
Where this fits in the timeline
The cleanest version of this conversation happens well before the purchase agreement is drafted. By the time the deal is in lawyer redlines, folding the tail in cleanly gets harder. The tax and legal sides of the deal structure belong with your attorney and your CPA. The coverage side belongs between you and whoever placed your E&O. More importantly, it belongs in the conversation before the letter of intent gets signed. It sits next to what the buyer is looking at on their side of the deal. The deals that close with the fewest surprises are the ones where both sides did their coverage homework.
If you are thinking about selling and you have not had a coverage conversation yet, this is the kind of question Canary's pre-sale coverage reviews start with. Pricing, scope, and what the deliverable looks like are on the M&A reviews page.
