Coinsurance, ACV, and a Tenant's Subrogation Waiver
Ridgeline Storage LLC insures a 12,000-square-foot warehouse under a commercial property policy with a $600,000 building limit, 80% coinsurance, $5,000 deductible, and ACV valuation. The building's replacement cost is $800,000. A tenant's employee leaves a space heater on, causing a fire that damages the roof and inventory. The loss runs $200,000 replacement cost; depreciation is $30,000. The lease says the landlord and tenant each waive all rights of subrogation against the other for fire loss, but the tenant's renters policy has $300,000 property coverage. The landlord's policy has a mortgage clause naming Delta Bank. The insurer pays the landlord, then considers subrogation against the tenant. The adjuster must also decide whether to apply ACV before or after coinsurance and whether the mortgagee gets a separate payment.
1. Calculate the building payment. Show the coinsurance calculation, the ACV step, and the deductible. Explain the order of operations.

Start with the coinsurance requirement: 80% x $800,000 replacement cost = $640,000. The limit carried is $600,000, so the coinsurance ratio is $600,000 divided by $640,000 = 0.9375. The covered loss at replacement cost is $200,000, but the policy is ACV, so subtract depreciation: $200,000 - $30,000 = $170,000 ACV. Apply the coinsurance ratio to the ACV loss: $170,000 x 0.9375 = $159,375. Then subtract the $5,000 deductible: $159,375 - $5,000 = $154,375. The order matters: coinsurance is applied to the covered loss before the deductible. If the policy's coinsurance clause says to apply the ratio to the loss before depreciation, the result could differ; read the clause. The payment is not $200,000 and not $170,000. Also confirm whether inventory is covered under a separate limit and whether the tenant's policy responds.
2. Does the lease's mutual subrogation waiver bar the insurer from pursuing the tenant? What should the adjuster do before paying?
Read the worked answer
The insurer's subrogation rights are derivative of the landlord's rights. If the landlord validly waived subrogation against the tenant before the loss, the insurer generally takes subject to that waiver and cannot pursue the tenant, even if the tenant's employee was negligent. The adjuster should obtain the full lease, confirm the waiver covers fire loss and the tenant and its insurer, and check whether the waiver is enforceable under Mississippi law. The adjuster should also determine whether the loss was caused by something outside the waiver, such as willful misconduct, and whether the tenant's renters policy has a waiver of subrogation in favor of the landlord. Do not pay first and then discover the waiver; document the analysis. If subrogation is barred, the insurer still owes the covered loss. If not barred, preserve evidence and put the tenant and its carrier on notice.
3. How should the mortgagee's interest be protected, and does the coinsurance penalty reduce the mortgagee's recovery?
Read the worked answer
Delta Bank's mortgage clause is a separate contract between the insurer and the mortgagee. The adjuster should identify the clause, confirm the mortgagee's interest, and include Delta Bank on the payment as its interest appears. Under a standard mortgage clause, the mortgagee is protected against acts of the borrower and usually receives loss payment to the extent of its interest, even if the insured's conduct would reduce the insured's recovery. The coinsurance penalty is generally charged against the insured's interest, not the mortgagee's protected interest, but the exact result depends on the clause language. The adjuster should not issue a check only to the landlord if the mortgagee is named. Obtain a mortgagee clause copy, confirm the unpaid principal balance, and coordinate any joint check or loss draft. Also preserve the insurer's right to subrogate against the tenant only if the waiver does not bar it; the mortgagee's rights should not be compromised by a quick settlement.
