Property Valuation & Loss Settlement

ACV vs. Replacement Cost vs. Functional Replacement

How an insurer values a loss is as important as whether the loss is covered. Three valuation methods dominate the exam.

• Actual Cash Value (ACV) = Replacement Cost − Depreciation. ACV reflects the property's depreciated, used value at the time of loss. A 10-year-old roof with a 20-year life is paid roughly half its replacement cost. ACV upholds indemnity — it puts the insured back in the same financial position, no better.
• Replacement Cost Value (RCV) pays to repair or replace with new materials of like kind and quality, with no deduction for depreciation, subject to policy limits and (usually) a requirement that the insured actually repair or replace. Many RCV provisions pay ACV first and the recoverable depreciation after the work is done.
• Functional Replacement Cost pays to replace damaged property with modern, functionally equivalent materials rather than identical ones. It is common on older or historic homes (and the HO-8) where rebuilding with original plaster, lath, or hand-carved details would be impractical or grossly over-value the loss.

A classic exam trap: ACV is not market value and not what the insured originally paid. It is replacement cost today minus accumulated depreciation.

The Coinsurance Clause — with a Worked Example

A coinsurance clause requires the insured to carry insurance equal to a stated percentage of the property's value (commonly 80%) at the time of loss. Carry less, and the insured becomes a co-insurer and shares in partial losses. The formula is:

Payment = (Did carry ÷ Should carry) × Loss − Deductible

Where "Should carry" = required percentage × property value.

Worked example. A building is worth $500,000. The policy has an 80% coinsurance clause, so the insured should carry 0.80 × $500,000 = $400,000. Suppose the insured actually carries only $300,000 and suffers a $100,000 loss with a $1,000 deductible.

1. Should carry: 0.80 × $500,000 = $400,000
2. Did carry: $300,000
3. Ratio: $300,000 ÷ $400,000 = 0.75 (75%)
4. Apply to loss: 0.75 × $100,000 = $75,000
5. Subtract deductible: $75,000 − $1,000 = $74,000 payable

The insured eats the remaining $26,000 as the coinsurance penalty for under-insuring. Two more rules: the payment can never exceed the policy limit, and a total loss is generally paid up to the full limit regardless of the coinsurance ratio (the penalty bites on partial losses). If the insured had carried the full $400,000, the formula ratio would be 1.0 and the loss would be paid in full less the deductible.

Deductibles, Valued Policies, and Stated Amount

A deductible is the portion of each loss the insured agrees to retain; it lowers premium and discourages small claims. Property deductibles are usually flat dollar amounts, though catastrophe deductibles (wind/hurricane) are often a percentage of the dwelling limit.

A valued policy pays a pre-agreed, fixed sum on a total loss without requiring proof of actual cash value — used where value is hard to establish at the time of loss, such as fine art or antiques, and mandated by some states' valued-policy laws for total fire losses to real property. A stated amount approach instead caps recovery at the lesser of the figure on the declarations or the property's value at loss — common on commercial equipment and specialty autos. An agreed value option, by contrast, waives the coinsurance clause when the insurer accepts the insured's statement of value.

Other Insurance, Subrogation, and Salvage

Three conditions prevent an insured from profiting from a loss and let the insurer recover.

Other insurance / pro rata. When two or more policies cover the same property and loss, a pro rata clause divides the loss in proportion to each policy's share of the total insurance, so the insured is indemnified once, never twice. Example: a $100,000 loss covered by a $150,000 policy and a $50,000 policy (total $200,000) is shared 75% / 25% — $75,000 from the first and $25,000 from the second.

Subrogation. After paying a covered loss caused by a negligent third party, the insurer succeeds to the insured's right to recover from that party. Subrogation prevents double recovery (the insured cannot collect from both the insurer and the wrongdoer) and shifts the ultimate cost to the at-fault party. The insured must not impair this right — for example, by signing a release before the loss.

Salvage. When the insurer pays for damaged or destroyed property, it gains the right to take possession of and sell the salvage, recouping part of the payout. A totaled vehicle the insurer pays off becomes the insurer's property to sell. Together, subrogation and salvage reinforce the principle of indemnity: the insured is made whole — and only whole.
