Severability
Severability, or separation of insureds, is a policy provision that treats coverage as applying separately to each insured, so one insured's conduct or misstatement generally does not defeat coverage for the others, though the policy limits remain shared.

How severability works
IRMI describes a severability of interests clause as one providing that, except for the limits, the insurance applies to each insured as though a separate policy had been issued to each. The clause is also called a separation of insureds condition, and it appears in the standard ISO commercial general liability form.
Two effects are common. First, a claim by one insured against another insured can be covered, rather than being blocked because both are insured under the same policy. Second, an act, statement, or breach by one insured may not eliminate coverage for other insureds who were not involved.
Severability has limits. It does not create separate limits for each insured: the limit is shared by everyone insured under the policy. Its effect also depends on the exact wording and on related provisions, such as exclusions that apply to "the insured" versus "any insured," and, in management liability policies, how knowledge in the application is imputed to individuals or the company.
Example
A company and its directors are covered under one management liability policy. An investigation later shows that the CFO knew a statement in the application was inaccurate. Under a severability provision, the insurer may be limited in denying coverage to directors who did not know about the statement, though the outcome depends on the policy wording and applicable law.
What to watch for
- Imputation language. Some policies specify whose knowledge is attributed to the company or to other insureds. Broader imputation weakens protection for innocent insureds.
- Shared limits. Severability does not multiply limits. If several insureds have claims, they draw on the same limit.
- "The insured" versus "any insured." Exclusions worded as "any insured" can defeat some of the effect of severability.
- Non-rescindable protection. Some D&O forms add stronger protections for individual insureds, and wording varies significantly.
Severability vs. related terms
- Separation of insureds. In general liability policies the same idea usually appears as a separation of insureds condition. The policy applies to each insured as though a separate policy had been issued, except for the limits. The named insured is usually the company, but others, such as directors and officers, are protected by the same clause. See commercial general liability for the broader form.
- Non-rescindable coverage. Severability limits how one person's conduct or knowledge affects other insureds. Non-rescindable language goes further for certain coverage, usually Side A, by restricting the insurer's ability to cancel or void the policy based on application misstatements. Some forms offer one without the other, so check both.
- Conduct exclusions. A conduct exclusion removes coverage for certain deliberate acts. In many D&O forms it applies only after a final adjudication and is meant to apply to the person who committed the act, which is where severability comes in.
- Insured versus insured exclusions. These typically bar claims by one insured against another, often with exceptions such as derivative suits. This is a separate provision, and how it interacts with severability depends on the wording.
- Shared limits. Severability treats insureds separately for coverage purposes. It does not give each insured its own limit, and payments for one reduce what is left in the aggregate limit for the others.
Second example: a conduct exclusion
A hypothetical venture-backed company and its five directors are sued by investors who allege fraud. A court later enters a final judgment that one executive committed deliberate fraud. The policy's conduct exclusion applies to that executive, and under a severability provision it generally would not apply to the four directors who were found to be uninvolved. Their defense costs and any covered settlement may still be paid from the shared limit, subject to the policy terms. Whether the company's own coverage is affected depends on how much of the executive's knowledge the policy attributes to the company, which is why imputation language matters.
Questions to ask your broker or underwriter
- Is there a full severability clause, and does it cover both application statements and exclusions, or only one?
- Whose knowledge is attributed to the company and to other insureds, for example only the signer of the application, or a broader group of senior officers?
- Are exclusions worded as "the insured" or as "any insured"?
- Is Side A coverage non-rescindable, and are there any carve-outs? See Side A, B and C for the structure.
- Would a dedicated Side A limit or an additional layer better protect individual directors if the shared limit is used up?
- How does entity coverage interact with the individual protections, and can entity claims use up the shared limit?
- Do outside directors and investor designees have separate protection through indemnification agreements or other policies, and how does that coordinate with this one?
Why it matters for technology, AI, fintech and digital-asset companies
Venture-backed companies often have several directors, officers, and investors on the same D&O policy. Application statements are typically signed by senior executives, so severability and non-rescindable language help determine whether innocent directors, particularly outside board members, keep protection if a problem emerges with the application.
Founders, investor designees and independent directors often sit on the same policy and have very different knowledge of the company's day-to-day statements. Because the application is usually signed by one or two executives, the severability and imputation wording decides whether other directors keep protection if the application turns out to be inaccurate. Fintech and digital-asset companies may also face regulatory inquiries that name specific individuals. In those cases severability helps keep one person's alleged conduct from affecting colleagues who were not involved, though each outcome depends on the facts and the policy. The same provisions often appear in employment practices and fiduciary liability coverage sold alongside D&O. See startup insurance by stage for context. A broker can compare severability, imputation and non-rescindable terms across quotes, which can differ more than price does.

Frequently asked questions
What is a severability clause?
Severability, or separation of insureds, is a policy provision that treats coverage as applying separately to each insured, so one insured's conduct or misstatement generally does not defeat coverage for the others, though the policy limits remain shared.
What is a severability of interests clause?
It is the specific wording that says, apart from limits, the insurance applies to each insured as if a separate policy had been issued to each. In a CGL policy it is commonly titled Separation of Insureds.
Does severability give each insured its own limit?
No. Coverage is applied separately, but the limit is shared among all insureds. If multiple insureds have covered claims, they draw on the same limit, and payments for one reduce what remains for the others.
What is the difference between severability and non-rescindability?
Severability treats each insured separately, so one person's conduct or knowledge may not defeat coverage for others. Non-rescindable language limits the insurer's right to void the policy, typically for individuals under Side A, based on application misstatements. Policies may offer one, both or neither.
Does severability apply in general liability policies?
Commonly, yes, as a separation of insureds condition. Standard general liability forms state that, except for the limits, the policy applies separately to each insured. How it affects a specific claim depends on the exclusions and the wording, so read both.
Can one executive's misstatement cost the whole board its D&O coverage?
It can lead to a coverage dispute, but severability, non-rescindable language and imputation terms are designed to protect innocent insureds. The outcome depends on the exact wording, the facts and applicable law, so review these provisions before you buy.
Does severability protect the company as well as individuals?
Not always. Many policies attribute the knowledge of certain senior officers to the company, so the entity may be affected even when other directors are protected. The imputation wording decides, which is why it is worth comparing between quotes.
