1.4 Policy Structure: Declarations, Insuring Agreement, Conditions, Exclusions

Reading a Policy Like an Underwriter

Nearly every standard ISO P&C policy is assembled from the same building blocks. The memory device is DICE: Declarations, Insuring agreement, Conditions, Exclusions. Modern ISO policies often add Definitions as a fifth, formal part. Knowing which part answers a given question is worth several easy points.

Declarations (the "Dec Page")

The front page, customized to the insured. It states the who, what, where, when, and how much:

• Named insured and mailing address
• Policy period (inception and expiration dates, 12:01 a.m. standard time)
• Description/location of the covered property or auto (VIN)
• Coverage parts in force and their limits of liability
• Premium and applicable deductibles
• Forms and endorsements attached by edition date (e.g., HO 00 03 ed. 2011, CA 00 01, CG 00 01)

Insuring Agreement and Definitions

The Insuring Agreement is the insurer's core promise — the broad statement of what is covered and the perils or basis of coverage. Two coverage triggers appear here:

Burden of proof rule (a classic trap): Under named perils, the insured must prove the loss came from a covered peril. Under open perils, the burden flips — the insurer must prove an exclusion applies.

Definitions assign precise meaning to bolded or quoted terms such as “insured,” “occurrence,” “bodily injury,” and “property damage.” A favorable definition can expand or restrict coverage as much as any clause.

Coverage-trigger nuance on liability forms: The ISO Commercial General Liability CG 00 01 is written on an occurrence basis — it responds to bodily injury or property damage that occurs during the policy period, no matter when the claim is reported. The alternative CG 00 02 is claims-made, triggered when the claim is first made, and adds retroactive dates and extended reporting ("tail") provisions. Distinguishing occurrence from claims-made is a frequent commercial-liability exam item.

Conditions

Conditions are the rules of the relationship — the duties each party must perform. Breaching a condition can suspend or defeat a claim. Common P&C conditions:

• Notice of loss — prompt notification to the insurer
• Duties after loss — protect property from further damage, submit a proof of loss, cooperate, allow inspection
• Appraisal — a dispute-resolution mechanism when the parties disagree on the amount (not coverage); each side picks an appraiser, who select an umpire
• Subrogation / Transfer of rights — the insured must preserve the insurer's recovery rights
• Cancellation and nonrenewal — procedures and notice periods
• Other insurance — how this policy coordinates with overlapping coverage
• Assignment — the insured generally cannot transfer the policy to another party without the insurer's written consent (the personal nature of the contract)
• Mortgagee/loss-payable — protects a lender's interest separately from the insured's, so a mortgagee may still collect even if the insured's own acts (e.g., arson) void the named insured's coverage

Appraisal vs. arbitration trap: Appraisal resolves disputes over the amount of a loss when coverage itself is not in question; it does not decide whether a loss is covered. If the dispute is about coverage, the appraisal clause does not apply.

Exclusions and a Coinsurance Worked Example

Exclusions carve coverage back out. They control catastrophic/uninsurable exposures (flood, earth movement, war, nuclear), losses better covered elsewhere (autos under a homeowners policy), and non-fortuitous losses (wear and tear, intentional acts). Always read exclusions with the insuring agreement — coverage is the agreement minus the exclusions, plus any endorsements that buy coverage back.

Many commercial property forms attach a coinsurance condition requiring the insured to carry a limit equal to a stated percentage (often 80%) of value, or share in the loss.

Coinsurance formula: (Did Carry ÷ Should Carry) × Loss − Deductible = Payment

Worked example: A building worth $500,000 with an 80% coinsurance clause should carry $400,000. The insured carries only $300,000 and has a $50,000 loss with a $1,000 deductible.

• Coinsurance factor: 300,000 ÷ 400,000 = 0.75
• 0.75 × $50,000 = $37,500
• − $1,000 deductible = $36,500 paid

The $13,500 shortfall is the penalty for underinsuring.

Key coinsurance traps: (1) The penalty applies only to partial losses — if the loss equals or exceeds the policy limit, the insured simply collects the limit. (2) Coinsurance compares the limit carried to the limit required (percentage × value), never to the loss itself. (3) If the insured carries the required amount or more, the factor is 1.0 (capped at 100%) and there is no penalty. Endorsements like agreed value suspend coinsurance entirely when the insurer accepts a stated value at inception.

Other-Insurance Provisions in the Conditions

When overlapping coverage exists, the other-insurance condition decides how policies coordinate: pro rata by limits (each pays its share, shown in 1.2), excess (one policy pays only after another is exhausted), or primary/escape clauses. Personal auto and homeowners forms specify their own other-insurance rules, so a claim involving two policies turns on reading both forms' conditions together.
