The renewal of an apartment owner’s property programme looks routine. The building limit is the same, the carrier is the same, the premium is up about fourteen percent and the client has agreed to it. And yet three things about the renewal would surprise the client after a storm, and one of them is not a proofing failure at all.

This post follows one illustrative property check in InsightProofing from the moment the issued policy arrives to the moment the client delivery summary is ready to sign. The insured, the carrier, the brokerage and every figure are invented Illustrative; the screens are the running product on that invented book.

OutcomeFour tracked corrections with the carrier, one overdue; a delivery held until they are settled; a summary that names the flood change in plain words

Two different questions: did they issue what we bound, and is it what the client had?

Policy checking asks two questions that are easy to blur. Proofing asks whether the carrier issued what was bound: the policy against the binder, the binder against the quote. Comparison asks what changed against the expiring policy: what the client is losing or gaining by renewing. A change can be perfectly proofed — quoted, bound and issued exactly as agreed — and still be the thing the client most needs to hear about.

On Bellwether Ridge, the flood sublimit is the example of the second kind. It was $10,000,000 on the expiring and $5,000,000 on the renewal quote, the binder and the policy. Nothing failed proofing, because the carrier issued exactly what was bound. But the renewal comparison reads it as narrower, and a proofing control says a narrowing must be named in the delivery summary.

Step by step

Bellwether Ridge, from the issued policy to the summary Day numbers are from the policy's arrival. Amounts are illustrative.
1
Issued policy uploadedDocumentsDay 0

The account manager adds the issued policy to the check. The expiring, the quote and the binder are already in the file; each is read page by page.

2
Documents sortedintake_agentDay 0

Four of four documents in the file. Nothing to ask the carrier or the client for.

3
Read into the coverage modelextraction_agentDay 0

Every document read into the property taxonomy: building and contents limits, business income, the all-other-perils and wind deductibles, flood and earthquake sublimits, valuation, coinsurance, premium, taxes, fees, commission. Each value keeps its page and the carrier’s own label.

4
Proofedproofing_agentDay 0

51 of 56 checks match. Four fail: the wind and hail deductible (2% bound, 5% issued), valuation (replacement cost bound, actual cash value issued), total cost and the premium arithmetic. One needs review: the wind mitigation subjectivity is still outstanding. It prepares raising the four failures with the carrier.

5
Compared with the expiringcomparison_agentDay 0

Six changes: premium, taxes and total cost up about 14%; wind and hail deductible, flood sublimit and valuation narrower.

6
Controls runsupervisor_agentDay 0

A high-severity failure is unresolved: delivery is blocked. Cover narrowed at renewal: the summary must say so. Total cost above $250,000? No — $196,220 — so no large-account referral.

7
Failures raisedAccount managerDay 0

Accepts the proofing checker’s prepared decision. Four correction requests are created, each citing the binder and the policy page.

8
Requests drafteddiscrepancy_agentDay 0

Drafts the request to the carrier’s underwriter: one line of context, then each correction exactly as the engine found it.

9
Requests sentAccount managerDay 1

Sends them, with a due date. Sending is capped at ask first, and in this build mail runs as a dry run until a brokerage connects its own.

10
One overdueSignalsDay 10

The total-cost request passes its due date; it shows on the practice leader’s home as an overdue correction and the carrier-slow control warns.

11
Summary drafteddelivery_agentLater

Only once every failure is corrected or waived. Until then the Delivery zone says exactly what is in the way.

What the screens show

Comparison · property
The Comparison zone on an illustrative property renewal
Comparison on a property renewal: premium and taxes up about 14%, the wind and hail deductible from 2% to 5%, the flood sublimit from $10M to $5M, valuation from replacement cost to actual cash value.

The comparison reads each change in the direction of the cover, not just the number. A higher deductible is narrower; a lower sublimit is narrower; actual cash value in place of replacement cost is narrower. The taxonomy records, field by field, which way is broader.

Proofing · property
The Proofing zone on an illustrative property renewal
Proofing on a property renewal: the wind deductible, valuation, total cost and the premium arithmetic fail, each already with the carrier.

The proofing zone shows the binder’s value and the policy’s value side by side, with a chip for each page. Each failure here already says With the carrier, because the requests have been raised.

Corrections
The Corrections zone with four illustrative requests to the carrier
Corrections: four requests to the carrier, one overdue and one acknowledged, each with its due date, the request and Follow up, Acknowledged, Corrected or Waive. Sending is a dry run in this build.

What the client has to hear

When the corrections are settled, the delivery writer drafts a paragraph for the client and a list of what changed. The control that fired guarantees the flood change is in it. The writer is held to the facts it was given: it may not add a number, a date or a form that is not among them, and an answer that does is thrown away in favour of the engine’s own wording.

Why this matters for E&O

A halved flood sublimit that the client agreed to is a business decision. A halved flood sublimit that the client was never told about is a broker’s problem. The difference is a sentence in the delivery summary — and a record that it was sent.

For the account team

One page shows what failed, what changed and what is with the carrier. The flood change cannot be forgotten: the summary will not be ready without it.

For broker IT

All six checks and six changes come from the engines over canonical fields; the model only drafts and explains. Every value has a page and a label.

For practice leadership

An overdue carrier request and a narrowing at renewal are both visible on the practice leader’s home, not in someone’s inbox.

Questions we get asked

Why isn’t the flood sublimit a proofing failure?

Because the carrier issued what was quoted and bound. Proofing is about whether the policy matches the deal; comparison is about what the deal changed. InsightProofing reports both, separately.

Who decides whether to accept actual cash value?

Not the agents. The account manager raises it with the carrier or, with a reason, waives it; waiving a high-severity failure refers the check to a practice leader.
