Property Insurance Valuation — ACV, RCV, and Replacement Cost Methods

An insurance binder is a temporary contract of insurance that provides coverage immediately, before the formal policy is issued and delivered. Binders are common in property and casualty insurance when coverage must take effect right away — for example, at closing on a home purchase, the lender requires proof of insurance before the loan funds. Binders are typically valid for a limited period (often 30-90 days) and contain the essential terms: parties, coverage amounts, premium, policy type. They can be oral or written, though written is universal in modern practice. Once the formal policy is issued, it replaces the binder. Binders can be revoked by the insurer with notice if underwriting concerns arise. Producers should not issue binders for risks they are not authorized to bind or for amounts above their binding authority.

Commercial property insurance uses 'Cause of Loss' forms attached to the basic property policy to specify what causes of loss are covered. Three standard ISO forms: (1) Basic Form (CP 10 10) — limited named perils including fire, lightning, explosion, windstorm, hail, smoke, aircraft/vehicles, riot, vandalism, sprinkler leakage, sinkhole collapse, volcanic action; (2) Broad Form (CP 10 20) — Basic perils plus falling objects, weight of ice/snow/sleet, water damage from plumbing, certain collapse situations; (3) Special Form (CP 10 30) — open perils (all causes of loss except those specifically excluded). The Special Form provides the broadest coverage at the highest premium. Choice of form depends on the business's exposure to losses, budget, and the underwriter's willingness. The cause of loss form is one of several form 'modules' that make up a commercial property policy.

Guaranteed Replacement Cost (GRC) — increasingly rare — pays whatever it costs to rebuild the home even if the cost exceeds the Coverage A limit, with no ceiling. Extended Replacement Cost (ERC) — more common today — pays beyond the Coverage A limit up to a specified percentage (typically 125% or 150% of Coverage A). Both provide protection against the common situation where rebuilding costs more than the policy limit due to inflation, code upgrades, or unexpected complications during construction. Without one of these features, a home insured for $400,000 that costs $480,000 to rebuild would leave the homeowner $80,000 short. ERC is often a standard feature on premium policies and an endorsement on basic policies; insurers often require periodic re-evaluation of the dwelling value to maintain the protection.

The Proof of Loss is a sworn (notarized) statement from the insured detailing the loss: date and circumstances, list of damaged or destroyed property with values, the insured's interest in the property, other insurance covering the loss, and the amount being claimed. Most property policies require submission of a Proof of Loss within a specified time, typically 60 days from the date of loss, though insurers often grant extensions. Failure to submit a timely Proof of Loss can compromise the claim, though state laws and the courts often require the insurer to show prejudice from late filing before denying the claim on that basis alone. The Proof of Loss formalizes the claim and starts the insurer's clock for paying. Photographs, receipts, repair estimates, and other documentation often accompany the Proof of Loss.

Binding authority is delegated authority from the insurer to the producer to commit the insurer to coverage on its behalf, without needing approval for each transaction. Property and casualty producers commonly have binding authority for standard residential and small commercial risks — they can issue binders or bind coverage at the point of sale, with the formal policy issued later. Binding authority has limits: maximum coverage amount, types of property eligible, geographic restrictions, exclusion of certain risks (high-value, complex, or unusual). Producers binding outside their authority expose themselves to errors and omissions liability. Life insurance producers typically have no binding authority — applications must be underwritten and approved before coverage begins, with optional conditional receipts providing limited interim protection.
