## Facts

- Great Northern Oil Company operated an oil refinery in Pine Bend, Minnesota.
- Great Northern purchased a three-year “all-risk” policy from multiple insurers covering, among other items, business-interruption losses, with aggregate limits of $3,000,000.
- The policy’s subrogation clause provided that upon payment the insurers would be subrogated to the insured’s recovery rights and that the insured would do nothing “after loss” to prejudice those rights.
- During the policy term, Great Northern contracted with Litwin Corporation for expansion construction work.
- The construction contract contained an exculpatory clause stating the contractor would not be liable for loss of use, loss of profits, or business interruption, however caused.
- A crane accident damaged partially completed work, and Great Northern claimed a substantial business-interruption loss.
- Great Northern sued the insurers for coverage; the insurers asserted that the exculpatory clause impaired subrogation and barred recovery.
- The trial court struck the insurers’ subrogation-impairment defense; the insurers appealed.

## Issues

1. Whether an insured’s pre-loss contractual release of a contractor from liability for business-interruption damages bars recovery under an “all-risk” policy by defeating the insurers’ subrogation rights.
2. Whether a subrogation clause prohibiting prejudice to subrogation rights “after loss” imposes any duty on the insured to preserve subrogation rights before a loss occurs.

## Decision

- The court affirmed the order striking the insurers’ defense.
- The insured’s pre-loss exculpatory agreement with the contractor did not preclude recovery for business-interruption loss under the policy.
- The policy language limited the insured’s duty not to impair subrogation to conduct occurring “after loss,” and the challenged release occurred before the loss.
- No equitable or public-policy basis justified denying coverage based on the pre-loss allocation of risk between commercially sophisticated parties.

## Legal Principles

- Subrogation rights are derivative; an insurer obtains no greater rights than the insured has and no broader protection than the policy’s terms provide.
- When a policy restricts impairment of subrogation rights only “after loss,” the insured does not breach the policy by entering pre-loss agreements that allocate or limit third-party liability.
- Courts will not rewrite an insurance contract to add pre-loss preservation requirements that the policy does not contain, particularly where the insurer could have drafted such protections.
- Pre-loss contractual allocation of consequential-loss risk in a commercial construction setting is generally enforceable absent a specific policy prohibition or a controlling public-policy concern.

## Conclusion

A pre-loss exculpatory clause releasing a contractor from business-interruption liability did not bar the insured’s recovery under an “all-risk” policy where the subrogation clause only prohibited prejudicing subrogation rights after a loss, and no equitable or public-policy reason warranted forfeiture of coverage.
