An agreed value endorsement suspends the coinsurance clause in a commercial property policy — but only until its expiration date. When it lapses, coinsurance reactivates silently, and the insured discovers the problem only after a loss. For public adjusters, a $100,000 coinsurance penalty on an otherwise straightforward claim almost always traces back to one of two things: the agreed value option was never in place, or it expired without anyone noticing.
Agreed value appears as Optional Coverage G.1 in ISO Form CP 00 10 (Building and Personal Property Coverage Form). It is activated by entry on the declarations page and requires the insured to submit a Statement of Values (ISO Form CP 16 15) listing the insurable value of all covered property. The insurer reviews the SOV, and the agreed value — along with an expiration date — is entered on the declarations.
That expiration date is the single most important detail. The suspension lasts until the earlier of 12 months after the effective date or the policy expiration. There is no automatic renewal. If the insured does not submit a new SOV and the option is not re-endorsed at renewal, coinsurance reactivates.
If you need a primer on how coinsurance works before going further, see our field guide on coinsurance and insurance to value.
What Does the Agreed Value Clause Actually Say?
The agreed value clause does not change how a loss is valued — it changes whether the insurer can penalize the insured for underinsurance. This is the distinction that matters for every comparison that follows.
The standard ISO language reads:
ISO Form CP 00 10, Optional Coverage G.1 — Agreed Value: "The Additional Condition, Coinsurance, does not apply to Covered Property to which this Optional Coverage applies... We will pay no more for loss of or damage to that property than the proportion that the Limit of Insurance under this Coverage Part for the property bears to the Agreed Value shown in the Declarations."
Plain-English translation: As long as the limit of insurance equals or exceeds the agreed value on the declarations, there is no coinsurance penalty. But if the insured reduces the limit below the agreed value, the policy applies a proportional reduction — similar in effect to a coinsurance penalty, just calculated against the agreed value rather than the time-of-loss replacement cost.
Most insurers apply a modest surcharge for the option.
The rule: Before writing a single line of scope, confirm the agreed value expiration date on the declarations page. If it has passed, treat the policy as coinsurance-active.
What Happens When Agreed Value Lapses?
The most common agreed value failure is not a coverage dispute — it is a lapse. The insured forgets to submit a new SOV, the broker doesn't request the endorsement at renewal, or the carrier quietly drops the option. Some carriers remove agreed value at renewal unless the insured affirmatively requests it — the declarations page for the new term simply omits the entry, and no one notices until a claim is filed.
Worked Example — Agreed Value Active vs. Lapsed:
A PA is retained on a fire loss at a commercial warehouse. The building's replacement cost is $2,000,000. The policy carries an 80% coinsurance clause, a limit of insurance of $1,200,000, and a $5,000 deductible. The fire damage totals $400,000.
Scenario A — Agreed Value Active (agreed value = $1,200,000):
Coinsurance is suspended. The insurer pays $400,000 minus the $5,000 deductible = $395,000.
Scenario B — Agreed Value Lapsed:
The agreed value expiration date passed three months before the loss. Coinsurance reactivates. Required insurance is 80% × $2,000,000 = $1,600,000. The insured carries only $1,200,000 — 75% of what is required. Penalty: ($1,200,000 ÷ $1,600,000) × $400,000 = $300,000 minus the $5,000 deductible = $295,000.
The lapse costs the insured $100,000 on a $400,000 loss.
This is not an edge case. Industry studies cited by Verisk have found that roughly 75% of commercial buildings are underinsured — which means the coinsurance clause has teeth on most commercial property claims. Agreed value is what keeps those teeth from closing.
There is a second trigger: if the insured reduces the limit of insurance during the policy term and the new limit falls below the agreed value on the declarations, the agreed value provision applies its own proportional reduction to any loss payment. The coinsurance clause may still be technically suspended, but the result is the same.
Warning: The agreed value endorsement does not guarantee full recovery. It guarantees only that the coinsurance formula will not reduce the payout. If the limit of insurance is inadequate for the loss, the insured absorbs the shortfall regardless.
Jurisdiction note: When a carrier asserts a coinsurance penalty — whether because agreed value lapsed or was never in place — the burden of proving the property's value at time of loss typically falls on the insurer. In Country Mut. Ins. Co. v. AAA Constr. Ltd. Liab. Co. (W.D. Okla. 2019), the court held that the insurer could not rely on an arbitrary valuation to invoke the coinsurance clause. PAs should not concede a penalty based solely on the carrier's valuation without demanding supporting documentation.
Action: On every commercial property intake, check two things — the agreed value expiration date and whether the current limit of insurance still equals or exceeds the agreed value. Either failure creates a penalty.
Agreed Value vs. Replacement Cost, ACV, and Stated Value
Agreed value is a coinsurance suspension mechanism, not a valuation method. It coexists with whatever valuation method the policy uses. The three most common points of confusion all turn on the same principle: agreed value determines whether a penalty applies, while the valuation method determines how the loss is calculated.
Agreed Value vs. Replacement Cost
Replacement cost is a valuation method (Optional Coverage G.3 on CP 00 10). It pays the cost to repair or replace damaged property with no deduction for depreciation. It does not suspend coinsurance. A policy with replacement cost but no agreed value endorsement still applies coinsurance at time of loss.
A policy with both gives the insured the strongest position: full replacement cost valuation with no coinsurance penalty. Whether the question is framed as agreed value vs replacement cost or replacement cost vs agreed value, the answer is the same — they are separate provisions, not alternatives.
Worked Example:
A retail building has a replacement cost of $3,000,000. The policy has a 90% coinsurance clause, a $2,000,000 limit, and replacement cost valuation. Wind causes $500,000 in roof damage. Deductible is $10,000.
With agreed value: Coinsurance suspended. Payment = $500,000 − $10,000 = $490,000.
Without agreed value: Required insurance = 90% × $3,000,000 = $2,700,000. The insured carries about 74% of required. Payment = ($2,000,000 ÷ $2,700,000) × $500,000 = $370,370 − $10,000 = $360,370. Difference: $129,630.
Agreed Value vs. Actual Cash Value
Actual cash value pays replacement cost minus depreciation. ACV is the default valuation on CP 00 10 unless replacement cost is endorsed. The confusion around agreed value vs actual cash value — sometimes shortened to agreed value vs ACV — persists because both appear on the declarations page, but they do different things.
When agreed value and ACV coexist, the agreed value suspends coinsurance but does not override depreciation. The insured avoids the underinsurance penalty but still receives a depreciated payout. On older commercial properties, the depreciation deduction will likely dominate the loss outcome — agreed value just prevents the coinsurance penalty from making it worse.
Agreed Value vs. Stated Value
Stated value is a policyholder-declared amount that serves as a ceiling on recovery but does not bind the insurer. The insurer typically pays the lesser of the stated value or the ACV at time of loss. The agreed value vs stated value distinction matters because there is no underwriting review of values and no coinsurance suspension with stated value. It is most common in auto and inland marine policies.
The critical difference: with agreed value, the insurer pays the full limit on a total loss (assuming limits equal the agreed value). With stated value, the insurer may pay less than the stated amount. The stated value is a ceiling, not a guarantee.
Action: When a client says their property is insured at "agreed value," the next question is: agreed value and replacement cost, or agreed value and ACV? The valuation method determines the settlement. If the policy says "stated value," read the loss settlement provision — the carrier may owe less than the number on the page.
Agreed Value for Business Income
The coinsurance penalty on a business income claim can dwarf the penalty on the property claim — and agreed value for BI requires separate activation. Most PAs check for agreed value on the property coverage and never look at whether business income has its own endorsement.
Under ISO Forms CP 00 30 and CP 00 32, the insured must submit a Business Income Report/Worksheet (ISO Form CP 15 15) and have the BI agreed value entered on the declarations with its own expiration date. The property agreed value endorsement does not extend to BI.
Worked Example — BI Coinsurance Penalty:
A beachfront restaurant has net income plus operating expenses of $800,000 for the 12 months following policy inception. The policy has a 50% coinsurance clause on BI and a $300,000 limit. No BI agreed value. A fire in June causes a six-month shutdown with $350,000 in lost business income.
Required insurance = 50% × $800,000 = $400,000. The insured carries $300,000, or 75% of required. Penalty: ($300,000 ÷ $400,000) × $350,000 = $262,500. The insured absorbs $87,500 in unrecovered BI loss — on top of whatever property penalty may also apply.
With the BI agreed value option active at $300,000, the penalty disappears. The payment would be $300,000 (the full limit). The $50,000 gap is a limit adequacy issue, not a penalty.
Action: On every commercial claim with a business income component, check the declarations for a separate BI agreed value entry and expiration date.
Agreed Value Intake Checklist
Run this before the first inspection report is written.
| # | Question | Why It Matters |
|---|---|---|
| 1 | Does the declarations page show an agreed value entry with an expiration date? | If no agreed value appears, assume coinsurance applies. |
| 2 | Has the expiration date passed? | The option expires on the earlier of its stated date or the policy expiration. If it has passed, coinsurance is active — even if the policy itself is still in force. |
| 3 | Was a new Statement of Values submitted at the most recent renewal? | A lapsed SOV means the option was not renewed and coinsurance is active for the current term. |
| 4 | Is the current limit of insurance ≥ the agreed value? | If the limit was reduced below the agreed value, the provision applies its own proportional reduction to any loss payment. |
| 5 | Is the underlying valuation replacement cost or ACV? | Agreed value suspends coinsurance but does not change the valuation method. An ACV policy with agreed value still deducts depreciation. |
| 6 | Is there a separate BI agreed value entry on the declarations? | BI coinsurance operates independently. If BI coverage lacks its own agreed value endorsement, the penalty can apply even when the property agreed value is active. |
| 7 | Is the property a historic building, church, or other hard-to-value structure? | These properties are most vulnerable to coinsurance disputes. Agreed value protects against the penalty; a current appraisal protects against the valuation gap. Both are needed. |
Agreed Value and Policy Analysis
The agreed value endorsement is a declarations-page item — a date and a dollar amount — that can lapse silently when the SOV isn't renewed, when the carrier drops the option at renewal, or when the property and BI endorsements expire on different dates. Any of these gaps reactivates coinsurance, and the first sign is typically a penalty applied to a claim.
Frontera surfaces agreed value status, expiration dates, and coinsurance percentages in coverage analysis reports — for both property and business income — with citations to the exact declarations and endorsement pages where the language appears. The goal is the same as this article: identify the coinsurance exposure before the first inspection report is written, not after the carrier applies the penalty.
