Coinsurance Clause vs Agreed Value on a Commercial Form
This quick reference card outlines key differences between two valuation terms on commercial property insurance forms. It is designed to help you organize your commercial property claim file folder, flag fields that require cross-checking with your broker, and avoid common entry errors when submitting supporting documentation for a filed claim. Margin Desk provides this educational reference only, and it does not replace guidance from your licensed insurance agent or claims adjuster. All entries you make on official forms should be verified against your active policy declarations page before submission.
Coinsurance Clause Form Field Entry Guidelines
Coinsurance clause fields appear in the “Policy Provisions” section of most standard ISO commercial property forms, typically labeled as boxes 14a through 14c on CP 00 10 documents. When filling these fields, enter the stated coinsurance percentage exactly as printed on your declarations page, with no rounding, adjusting, or reformatting to match your current property value, as this is one of the most common errors that delay claim processing. The field labeled “Insured Value Submitted for Coinsurance Calculation” must match the total building and contents value you listed on your initial policy application, unless you have filed a formal mid-term endorsement updating that value with your carrier. If your policy covers multiple buildings under a single plan, each building may have its own coinsurance percentage, so you must fill out a separate field set for each property, do not average percentages across all locations, as this will lead to incorrect payout eligibility calculations. Illustrative example: If your policy lists an 80% coinsurance requirement, enter 80.0 in the percentage field, not 80 or 0.8, to match standard form formatting requirements.
Agreed Value Endorsement Line Item Breakdown
Agreed value endorsements are optional policy add-ons that waive coinsurance requirements, so they appear in the “Endorsements Attached” section of your form, not the core policy provisions. The standard line items for this section follow a consistent structure across most carrier forms, and entries must adhere to strict requirements to be considered valid. Line 1: Effective Date of Agreed Value, which must match either your policy effective date or the endorsement effective date if added mid-term, do not enter the date of your property appraisal, as this is a frequent submission error. Line 2: Agreed Building Value, which must be exactly the value listed on the appraisal you submitted to your carrier when you requested the endorsement, no adjustments for post-appraisal renovations are allowed unless you have a separate updated endorsement on file. Line 3: Agreed Contents Value, which follows the same rule, and must match the documented inventory value on file with your carrier, not your current inventory value at the time of loss. Line 4: Waiver of Coinsurance Confirmation Box, which you only check if the endorsement was active on the date of the claimed loss, not the date you are filling out the form. If your policy covers multiple locations, each location will have its own separate agreed value line item on the endorsement, so you must enter the value specific to the location where the loss occurred, do not enter the total agreed value across all locations, as this will overstate your eligible payout and trigger a review flag on your submission. Illustrative example: If your agreed value endorsement was effective January 1, 2023 through December 31, 2023 and your loss occurred on January 5, 2024, you cannot use the agreed value fields even if you are in the process of renewing the endorsement.
| Form Field Name | Coinsurance Clause Entry Requirement | Agreed Value Endorsement Entry Requirement | Supporting Documentation to Attach |
|---|---|---|---|
| Valuation Percentage Field | Enter exact coinsurance percentage from your declarations page (e.g., 80.0 for an 80% requirement), no rounding or decimal adjustments | Leave blank unless your endorsement explicitly lists a residual coinsurance requirement for partial losses | Copy of the declarations page policy provisions section |
| Insured Value Entry Field | Enter total insured value as listed on your declarations page, no adjustments for current market value or post-policy improvements unless a formal endorsement is on file | Enter the exact agreed value for the specific damaged property segment (building, contents, etc.) as listed on your active endorsement | Copy of original policy application (coinsurance) or signed endorsed valuation agreement (agreed value) |
| Loss Amount Calculation Field | Enter full replacement cost of damaged property with like-kind and quality, no pre-emptive depreciation deductions | Enter full replacement cost of damaged property, no additional coinsurance formula application required | Copy of licensed contractor repair estimate or itemized inventory loss list |
| Waiver of Coinsurance Checkbox | Leave unchecked, even if you believe you meet the minimum coinsurance requirement, as the adjuster will verify eligibility | Check only if your agreed value endorsement was fully active on the reported date of loss | Copy of endorsement effective and expiration date confirmation |
| Payout Request Field | Enter calculated payout amount after coinsurance adjustment and applicable deductible subtraction, capped at your policy limit | Enter loss amount minus applicable deductible, capped at the agreed value for the specific damaged property segment | Copy of your own step-by-step math worksheet showing how you arrived at the requested amount |
Claim Payout Calculation Box Input Rules
These boxes appear on the proof of loss form you submit to your carrier after a covered loss, not on your initial policy application, and entries must be aligned with either the coinsurance clause or agreed value endorsement rules, with no mixing of inputs between the two methods. If you are using the coinsurance clause method, first enter the full replacement cost of the damaged property in the first input box, with no deduction for depreciation. Next, enter the total insured value of the full property as listed on your declarations page, followed by the coinsurance percentage pulled directly from your policy provisions. Calculate the minimum required insured value as (full property value * coinsurance percentage): if your insured value meets or exceeds that minimum, you are eligible for full payout up to your policy limit, minus your deductible. If your insured value is lower than the minimum required, your payout is calculated as (actual insured value / minimum required value) * total loss amount, minus your deductible. If you are using the agreed value method, enter the agreed value of the damaged property segment pulled directly from your endorsement, followed by the documented loss amount from your repair estimate or inventory list. No coinsurance calculation is required, and your payout is capped at the agreed value for that segment, minus your deductible. Document all calculations on a separate worksheet attached to your proof of loss form, even if you are using the agreed value method, so the adjuster can quickly verify your math without requesting additional information. Illustrative example: If your agreed building value is $1,200,000 and you have a $400,000 covered loss, you enter $1,200,000 in the agreed value input and $400,000 in the loss amount field, no additional math is required beyond subtracting your deductible.
Property Valuation Schedule Attachment Notes
Regardless of which valuation method applies to your claim, you must include a full property valuation schedule in your claim file folder, tabbed for quick access by the adjuster. For coinsurance claims, your schedule must include the original policy application valuation, any mid-term updates to property value you have filed with your carrier, and a current replacement cost appraisal dated within 12 months of the loss date, to verify that you met the coinsurance requirement at the time of loss. If you have made permanent improvements to the property after your policy was issued, include receipts for those improvements in the valuation schedule attachment, as they may increase your total insured value for coinsurance purposes. For agreed value claims, your schedule must include the signed agreed value endorsement, the original appraisal submitted to the carrier when the endorsement was issued, and written confirmation that the endorsement was active on the loss date. No current appraisal is required for agreed value claims unless the carrier specifically requests it. All schedules should be sorted by property type (building, permanent fixtures, contents, business personal property) to match the line items on your policy form, and no handwritten changes to the schedule are allowed unless they are initialed by your broker and attached as a separate addendum. Keep a full copy of the valuation schedule in your own records, separate from the copy you submit to the carrier, for your reference during the claims process.
Policy Declarations Page Comparison Markers
Create tab markers on your declarations page for the following items to cross-reference with your form entries before submission, to reduce processing delays and avoid entry errors. First, highlight the coinsurance percentage in yellow, and confirm it matches the number you entered in the coinsurance clause field, if applicable. Second, highlight the agreed value endorsement indicator in blue, and confirm that the endorsement number listed on the dec page matches the number on your attached agreed value form. Third, highlight your total policy limit in green, and confirm that the payout amount you entered in the calculation boxes does not exceed this limit, as payouts are capped at the policy limit regardless of valuation method. Fourth, highlight your deductible amount in pink, and confirm that you have subtracted the correct deductible from your requested payout amount, no adjustments to the deductible are allowed without written confirmation from the carrier. You should also mark the policy period on your dec page, to confirm that the loss occurred within the active policy period, as neither valuation method applies to losses that happen before your policy starts or after it expires, even if you have submitted a renewal application. If your dec page lists any exclusions that apply to your type of loss, flag those as well, to confirm that your claim is eligible for coverage before you spend time filling out valuation fields.
Before submitting your next commercial property claim form, cross-check all valuation field entries against your highlighted declarations page and attach the required supporting documentation to your file folder to reduce processing delays.
