A box of auto parts can be finished and ready to ship without being “finished stock” under an insurance policy. A recent Michigan decision illustrates why definitions matter and why a policyholder can demand appraisal without winning every coverage argument. 1
In Aicheh, LLC v. Verlan Fire Insurance Company, a federal court considered Detroit Axle’s claim following two storms that sent rainwater through its warehouse roof. The water damaged conveyors, storage racks, and inventory. Verlan paid more than $1.1 million for personal property damage and extra expenses but disputed the business income claim and refused the requested appraisal.
The policy language and definitions were extremely important. A special provision excluded “inventory/stock,” defined as raw materials, finished stock, and work in progress. The business income endorsement described finished stock as “stock you have manufactured.” Detroit Axle bought the parts for resale; it did not manufacture them. The court rejected the insurer’s attempt to stretch that definition to encompass the retailer’s merchandise. An insurer cannot replace its chosen definition with a broader industry understanding simply because the broader meaning helps defeat a claim.
However, Lloyd’s separately insured the inventory. The court applied Verlan’s provisions elsewhere in the policy addressing property insured, which included an excess exception. Under the ruling governing this appraisal, the inventory was not Covered Property. Winning the finished-stock argument therefore did not establish inventory coverage. This is why reading one exclusion is never enough.
Detroit Axle nevertheless won its demand for appraisal. The conveyors and racks were covered property, and the remaining dispute concerned how much business income loss resulted from that covered damage. The court resolved the policy interpretation questions and directed the appraisers to decide the factual causation and amount issues within those boundaries. It expressly prohibited an award that treated the inventory as Covered Property. The order sent the claim to appraisal, but the policyholder lost part of the coverage battle.
For business owners and agents, the practical lesson begins before the loss to make sure separately purchased inventory insurance fits with the business income coverage. The practical lesson for claims practitioners is that after a loss, document when sales declined, how damaged equipment impaired operations, and why relocation becomes necessary. Separate losses attributable to covered equipment from those attributable to inventory or other causes. A convincing business income claim needs a documented explanation of how the covered damage cost the business money.
