Automating Rate Adequacy File Reviews for Underwriter Portfolio Audits (Property & Homeowners, General Liability & Construction, Specialty Lines & Marine) - Underwriting Manager

Underwriting Managers live with a constant tension: you need defensible rate adequacy across thousands of in‑force policies, yet your teams are buried in manual review of endorsements, rating worksheets, and schedules that never look the same twice. Portfolio audits that should take days stretch into weeks, and the risk of missing a critical rating factor or hidden endorsement grows with each page. That’s precisely the challenge Nomad Data built Doc Chat to solve.

Doc Chat for Insurance is a suite of purpose‑built, AI‑powered agents that bulk‑process entire policy files—ingesting thousands of pages at a time—then extracting, reconciling, and surfacing the exact rating factors, limits, deductibles, and endorsements you need for rate adequacy file reviews and portfolio audits. For Property & Homeowners, General Liability & Construction, and Specialty Lines & Marine, Doc Chat converts in‑force policies, endorsement schedules, and rating worksheets into a clean, auditable dataset your underwriting and actuarial teams can trust.

Why rate adequacy reviews are uniquely hard for Underwriting Managers

In theory, rate adequacy audits are straightforward: confirm that the pricing factors used at bind/renewal match filed or approved rating plans and that endorsements align with appetite and risk selection standards. In practice, Underwriting Managers face sprawling document variability, inconsistent metadata, and institutional knowledge that lives in people’s heads rather than playbooks. Policy files span versions of ISO/AAIS forms, bespoke manuscript endorsements, and carrier‑unique rating worksheets—often revised mid‑term. Across Property & Homeowners, General Liability & Construction, and Specialty Lines & Marine, these nuances multiply.

Property & Homeowners: COPE and cat nuance in every paragraph

Property rate adequacy hinges on COPE data completeness and accuracy, catastrophe posture, and form‑specific modifiers that are frequently buried in endorsements. Underwriting Managers must reconcile reported TIV against Statement of Values (SOV), confirm protection class and distance‑to‑hydrant, verify construction/roof details, and account for cat deductibles and exclusions. Key materials often include dec pages, schedule of forms and endorsements (e.g., CP 04 11 Protective Safeguards, CP 04 05 Ordinance or Law, wind/hail or named‑storm deductibles), inspection reports, and loss control recommendations. In Homeowners, HO‑3 vs. HO‑5 nuances, roof surfacing ACV endorsements, water back‑up, and ordinance or law coverage levels all impact indicated rates and adequacy.

General Liability & Construction: class codes, subcontractor costs, and AI limits

GL rating factors are notoriously scattered: class codes, territory, payroll/receipts, and subcontracted costs are documented across ACORD 125/126 applications, rating worksheets, certificates, and endorsements. For construction, endorsements such as CG 20 10 and CG 20 37 (Additional Insured—Ongoing/Completed Ops), CG 21 39 (Contractors—Subcontracted Work), primary/noncontributory wording, and waiver of subrogation can materially affect exposure and pricing. Confirming whether subcontractor warranties are in place, whether evidence of insurance exists, and whether AI coverage was effectively limited is a painstaking exercise—and a key determinant of rate adequacy on wrap‑ups, project‑specific policies, and practice programs.

Specialty Lines & Marine: warranties, trading limits, and manuscript endorsements

Marine and specialty lines files add complexity through navigational warranties, trading limits, crew numbers, cargo types and stowage, warehouse‑to‑warehouse clauses, and tailored exclusions. Underwriting Managers must map hull inspections and classification society certificates to warranties; review Institute Cargo Clauses (A/B/C); and reconcile open cargo policy schedules, bills of lading, and survey reports. Manuscript endorsements are common, and their effects on rate and exposure—especially deductibles, sublimits, and trip limitations—are easy to miss in manual review.

How the process is handled manually today

Most Underwriting Managers still rely on sampling and human review to determine rate adequacy. The current state can be summarized as slow, variable, and difficult to scale:

Export an in‑force list from the policy admin system or data warehouse, then identify target cohorts for audit (e.g., Property coastal band, Construction GL with high subcontractor spend, Marine hull under 100 GT).
Download policy files from document management: dec pages, full in‑force policies, endorsement schedules, rating worksheets, ACORD applications, SOVs, inspection reports, and loss runs.
Recreate or trace rating: reconcile rating worksheets to class codes, territory, base rates, schedule credits/debits, experience rating or loss sensitive plans, and endorsements affecting exposure or coverage.
Validate factors across documents: e.g., GL receipts/payroll vs. tax returns; Property TIV vs. SOV; Marine crew size vs. payroll declarations; HO roof age vs. inspection photos.
Capture findings in spreadsheets; follow up with underwriters or brokers for missing documents; iterate until comfortable you can defend rate adequacy for the audited slice of the book.

Two issues recur: the team never reviews every policy due to time constraints, and institutional judgment—“what to check and in what order”—is inconsistent across reviewers. That drives both audit variability and the lingering fear that the portfolio has hidden leakage from misapplied factors or endorsements.

AI review of rate adequacy files: how Nomad Data’s Doc Chat automates underwriting portfolio audits

Doc Chat replaces tedious manual review with AI agents trained on your underwriting playbooks. It ingests entire policy files—in‑force policies, endorsement schedules, rating worksheets, ACORD 125/126/140 applications, SOVs, inspection reports, survey documents, and broker correspondence—then delivers a portfolio‑wide, auditable extraction of the exact data you need for rate adequacy file reviews.

Bulk ingestion at scale: Process thousands of policy files at once; Doc Chat handles inconsistent formats, scans, and mixed file types, turning unstructured content into structured, review‑ready data.
Rating factor extraction: Pull GL class codes and descriptions; payroll/receipts/subcontractor costs; territory; base rates and modifiers; Property COPE (construction, occupancy, protection, exposure), TIV by location, ISO PPC class, distance to hydrant/station, roof age/material; Marine vessel type, tonnage, crew count, trading limits, cargo classes, and warranty terms.
Endorsement mapping: Identify and normalize ISO/AAIS and manuscript endorsements across the book—e.g., CG 20 10, CG 20 37, CG 21 39; CP 04 11, CP 04 05; HO roof surfacing ACV; named storm/wind/hail deductibles; marine navigational warranties and Institute Cargo Clauses—and tie them to pricing or exposure impacts.
Reconciliation & cross‑checking: Compare rating worksheets with dec pages and endorsement schedules; flag mismatches (e.g., TIV variance between dec and SOV; GL receipts not aligning with rating base; endorsements referenced but not attached).
Portfolio analytics out of the box: Export a clean spreadsheet with rating factors, limits, deductibles, sublimits, and key endorsements for actuarial rate indication and management reporting—no manual stitching required.
Real‑time Q&A: Ask, “List all policies with CG 20 37 attached but no subcontractor warranty,” or “Show Property accounts with PPC ≥ 8 and roof age > 15 years.” Doc Chat answers instantly, with page‑level citations.
Playbook presets: Nomad configures “Rate Adequacy Audit” presets that codify your steps: what to extract, how to calculate, and how to present. Every reviewer gets the same process, every time.

This is not generic summarization. It’s targeted, repeatable review tailored to the exact rating logic and appetite of your underwriting organization.

Deep dive: examples by line of business

Property & Homeowners

Common audit goals: validate TIV and COPE accuracy; ensure protection class and distance‑to‑hydrant are captured; verify roof age/material; confirm cat deductibles and exclusions; verify ordinance or law and water back‑up endorsements align with appetite and pricing. Doc Chat extracts and reconciles these data from dec pages, location schedules, inspection reports, and endorsements, then highlights inconsistencies such as SOV/dec mismatches or missing Protective Safeguards (CP 04 11) where credits were applied.

Impact: more accurate rate indications; quicker identification of under‑deducted coastal risks; improved defensibility for catastrophe pricing and reinsurance negotiations.

General Liability & Construction

Common audit goals: verify class codes and rating bases (payroll/receipts/subcosts); map subcontractor exposure; confirm AI/PNC/waiver endorsements presence; validate per‑project aggregate limits and completed operations posture. Doc Chat aggregates GL rating worksheets with endorsements and ACORD data to flag: class code drift, missing contractor warranties, AI endorsements without required COIs, and schedule debits/credits applied without supporting documentation.

Impact: cleaner exposure data; improved recognition of risk transfer gaps; fewer unearned credits; transparent rationale for premium adjustments or endorsements at renewal.

Specialty Lines & Marine

Common audit goals: confirm navigational warranties and trading limits; reconcile crew counts and payroll; isolate cargo classes and stowage requirements; map manuscript endorsements that alter deductibles, sublimits, or voyage terms. Doc Chat reads hull surveys, classification certificates, open cargo schedules, and bills of lading to extract and normalize terms, flagging any variance between rating worksheets and actual imposed warranties.

Impact: clearer understanding of earned exposure; better alignment between price and navigational limits; faster identification of manuscripted drift from filed intent.

Beyond extraction: reconcile, calculate, defend

Underwriting Managers need more than raw fields. Doc Chat performs cross‑checks and calculations that mirror your team’s manual process. Examples include:

Variance tests: Compare TIV on the dec page to summed SOV by location; flag deviations beyond thresholds.
Exposure coverage checks: Confirm GL endorsements (AI/PNC/waiver) match stated project/contracts; identify missing COIs referenced in files.
Deductible posture: Normalize cat deductibles (e.g., 1%, 2%, 5% named storm) for portfolio‑level analysis by peril and geography.
Schedule credit/debit traceability: Link each credit/debit on the rating worksheet to documented justification in the file.
Warranties vs. reality: For marine, tie warranties to survey findings and crew manifests; highlight misalignments that impact adequacy.

Every finding links back to source pages for quick verification, combining speed with an audit trail strong enough for internal risk, actuarial peer review, reinsurers, and regulators.
