Bulk Loss Run Extraction for Reinsurance Due Diligence: AI-Driven Risk Assessment at Portfolio Scale

Reinsurance due diligence has a bottleneck that every Chief Underwriting Officer knows too well: loss information arrives in dozens of formats across hundreds of cedents, from PDFs and spreadsheets to scanned images and ad-hoc exports. The clock is ticking toward renewal or acquisition close, yet your team must reconcile paid, case, and incurred across cedent-specific definitions, stitch together accident and report years, and determine whether development and tail risk align with your appetite. In short, the data you need is buried inside unstructured documents and inconsistent bordereaux.

Nomad Data’s Doc Chat was built to fix this. It automates the extraction and normalization of loss run data from massive reinsurance submissions—Loss Run Reports, Cedent Loss Bordereaux, Schedule F (NAIC) filings, and Claim Register Exports—at portfolio scale. Where traditional approaches stall on volume and variability, Doc Chat turns days of manual review into minutes of machine-driven analysis and real-time Q&A. For reinsurers searching for “AI to extract claims from loss runs for reinsurance,” “bulk loss run data digitization for portfolio review,” “normalize ceded loss data with AI,” and “automated loss bordereaux analysis reinsurance,” this is the shortcut to clean, comparable data and confident underwriting decisions.

The Reinsurance Due Diligence Challenge for a Chief Underwriting Officer

As a CUO, you are responsible for portfolio-level performance as much as individual treaty outcomes. That means validating cedent quality, reserve adequacy, reporting discipline, data completeness, and overall loss emergence patterns—not just the current loss pick. But the documents you receive rarely line up neatly. Consider the variety your team sees across a typical renewal season:

Document and form types: Loss Run Reports and Cedent Loss Bordereaux with custom column headers and footnotes; Claim Register Exports from claims systems with shifting field names; Schedule F (NAIC) detail to corroborate ceded/assumed, recoverables aging, and counterparty concentrations; and accompanying treaty slips, endorsements, and exposure schedules. One cedent’s “ALAE” includes defense costs; another excludes it. Some report salvage/subrogation net, others gross. Currency conversions, occurrence vs. claims-made triggers, retro dates, sublimits, reinstatement charges—nuance lives in the fine print and footnotes.

On long-tail casualty, you need to understand triangle shape, IBNR assumptions, and whether case reserving is conservative or optimistic. On property cat, you must reconcile event coding, aggregation logic, and how the cedent treats hours clauses. Across lines, you care about clustering of large losses, latency in reporting, frequency/severity trends, and emergence relative to prior actuarial indications. All of this starts with accurately digitizing and normalizing loss runs—fast enough to impact pricing, terms, and participation decisions.

How the Process Is Handled Manually Today

Most reinsurance underwriting teams still rely on manual lift. Analysts request a “standard template,” but the reality is submissions arrive in whatever the cedent can produce. Your team downloads zip files, opens 50+ spreadsheets and PDFs, and begins the grind: copying columns, mapping values, writing macros, stitching together accident and report years, reconciling totals to the cedent’s cover memo, and building pivot tables and triangles. For scanned PDFs, they hand-key critical fields or attempt brittle OCR. When fields like paid ALAE vs. paid loss are co-mingled, a separate reconciliation is required. When a cedent provides only incurred totals, your actuaries must approximate development using external benchmarks rather than cedent-specific history. All of this occurs while the calendar compresses around treaty negotiations.

The cost of this manual approach is significant:

• Cycle-time drag: Weeks lost to formatting, cleaning, and rework before modeling can even begin.
• Inconsistency risk: Different analysts make different mapping choices, leading to uneven comparability across cedents.
• Human error: VLOOKUPs break, columns shift, and hidden filters skew results—exactly when precision matters most.
• Limited coverage: With finite analyst hours, you review deeply on a subset of cedents and skim the rest, inviting blind spots in tail risk and development behavior.
• Negotiation disadvantage: Without timely, portfolio-wide insights, you negotiate from assumptions rather than data-backed evidence.

What “Good” Looks Like for Portfolio-Scale Reinsurance Due Diligence

In an ideal world, every cedent’s Loss Run Reports, Cedent Loss Bordereaux, Schedule F exhibits, and Claim Register Exports flow into a normalized schema with transparent lineage back to source pages. Your team can filter and compare apples-to-apples across cedents and years, produce triangulations, and stress test tail assumptions—on demand. You can ask: Show all casualty claims with incurred > $1M where report lag > 24 months; reconcile paid loss plus paid ALAE vs. reported recoveries; list events mapped to an industry catalog for the last five wind seasons; and highlight any cedent whose development diverges by more than 10% from prior three-year indications.

What you need is not just OCR and a CSV. You need a purpose-built reinsurance document intelligence layer that performs inference—understanding what a field means in context, not just what a header says. As Nomad argues in “Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs,” the value comes from encoding the unwritten rules your top analysts use to interpret inconsistent documents, then applying them consistently at scale.

How Doc Chat Automates Bulk Loss Run Extraction and Normalization

Doc Chat is a suite of AI-powered agents trained on insurance documents and reinsurance workflows. For CUOs and portfolio leaders, it delivers end-to-end automation: ingest, classify, extract, normalize, cross-check, summarize, and analyze—then answer questions in natural language with page-level citations. It was designed specifically for the kind of multi-cedent, multi-format ingestion that overwhelms manual teams.

1) High-volume ingestion and smart classification

Drag-and-drop entire submission folders—spreadsheets, PDFs (native or scanned), emails, and zipped packages. Doc Chat detects document types such as Loss Run Reports, Cedent Loss Bordereaux, Schedule F (NAIC), and Claim Register Exports, routes them to the correct pipelines, and associates them to the proper cedent and treaty year. As documented in our medical review benchmark, Doc Chat can process extremely large volumes rapidly, transforming workflows that once took weeks into minutes (“The End of Medical File Review Bottlenecks”).

2) Field-level extraction tuned for reinsurance

Doc Chat pulls the facts reinsurers need, even when names differ across cedents. It handles both structured files and irregular layouts, extracting and tagging fields into a standard schema. Example fields include:

• Cedent identifiers: company, group, line of business, treaty/year, program type (quota, surplus, XOL), occurrence vs. claims-made
• Claim-level: claim number, policy number, insured name, peril/code, cause of loss, accident date, report date, state/territory, NAIC code/classification
• Financials: paid loss, paid ALAE, case loss, case ALAE, total incurred, recoveries (salvage/subro), deductibles, attachment/limit, reinstatement premiums
• Time features: report lag, settlement date, reopen indicator, litigation flag
• Structure cues: sublimits, aggregates, hours clauses, retro dates, exclusions referencing endorsements

This is far more than basic extraction. Where a cedent’s export uses “LAE” without clarity, Doc Chat inspects footnotes and companion documents to infer whether defense costs are included in loss or allocated separately. It does not guess; it cites the exact page(s) where the inference comes from so your team can verify instantly.

3) Normalization and comparability across cedents

Once extracted, Doc Chat maps every field to a shared taxonomy so your portfolio views are comparable. Encounter a new cedent? Nomad’s white-glove team trains the system on your playbooks, cedent-specific quirks, and preferred output formats. That is how we deliver what many CUOs search for as “normalize ceded loss data with AI”—not a generic template, but a living schema tuned to your underwriters and actuaries. Our perspective on building these custom, inference-capable agents is detailed in “AI’s Untapped Goldmine: Automating Data Entry.”

4) Quality checks and exception handling

Doc Chat applies automated QC so your team reviews exceptions rather than rework the entire pipeline. Typical checks include:

• Balance tests: paid + case = incurred; paid ALAE + paid loss = total paid
• Date consistency: report date not before accident date; reopen date after close date
• Currency harmonization and rounding tolerance
• Coverage logic: occurrence vs. claims-made trigger alignment; retro dates respected
• Triangle readiness: accident/report year completeness for each cedent
• Footnote and assumption capture: flags where cedent definitions differ from your standard

Exceptions are summarized with suggested fixes and links to source pages. If human confirmation is required, Doc Chat routes the item for review and learns from your disposition to reduce future exceptions.

5) Real-time Q&A across the entire submission

Ask natural-language questions across thousands of pages and rows and get answers with citations: “List all claims with incurred > $500K where report lag > 12 months,” “Which losses exceed attachment but fall under sublimits?” or “Show property cat events mapped to our event catalog and reconcile to cedent totals.” As our clients saw in claims workflows, this question-driven approach changes how teams work (“Great American Insurance Group Accelerates Complex Claims with AI”).

6) Delivery in your systems and formats

Doc Chat exports clean, normalized datasets to the tools your underwriters and actuaries use—CSV, Excel, data warehouses, or directly into pricing and reserving models. It also generates portfolio-ready visuals and triangulations so you can move from ingestion to insight without waiting on manual data wrangling.

Automated Analytics That Matter to Reinsurers

Clean, comparable data enables portfolio-level analytics that a CUO can rely on. With Doc Chat’s end-to-end pipeline in place, your team gets out-of-the-box answers to questions that used to require weeks of aggregation. Examples include:

Tail risk and development shape: Build accident-year and report-year triangles by cedent, class, and layer. Compare development against prior picks and peer patterns. Spotlight cedents where incurred development materially diverges from history, and where case reserving appears volatile or systematically optimistic.

Large loss clustering and volatility: Identify heavy-tailed cedents, outlier severity, litigation flags, and reopen patterns. Measure concentration risk by peril, geography, insured, and industry. Align excess attachment points to actual emergence behavior rather than generic benchmarks.

Property cat event normalization: Map cedent-reported events to your standard catalog and reconcile totals to loss runs, handling hours clauses and multiple occurrences per policy period.

Counterparty and collectibility checks: Cross-reference cedent recoverables against Schedule F aging and counterparty exposure, confirming alignment with reported ceded/assumed balances and highlighting potential collectibility risk.

Exposure alignment and terms impact: Tie loss experience to treaty structures—quota share vs. surplus vs. XOL—and quantify the impact of sublimits, aggregates, reinstatement provisions, and exclusions on net results. “Automated loss bordereaux analysis reinsurance” moves from aspiration to daily reality when the underlying data is clean and comparable.

Business Impact: Speed, Cost, Accuracy, and Negotiation Leverage

When Doc Chat automates the front-end document grind, your underwriting and actuarial teams redirect their time to analysis and strategy. The benefits show up immediately:

Cycle-time compression: Reviews that once took weeks compress to hours or minutes. Nomad’s AI routinely ingests and analyzes massive document sets in real time, as described in our client stories and in “Reimagining Claims Processing Through AI Transformation.” Faster readiness means you price more opportunities, negotiate from facts, and avoid extension risk.

Lower expense and less rework: Manual data wrangling and re-keying disappear. Analysts focus on exceptions and insight generation. As highlighted in “AI’s Untapped Goldmine,” the ROI compounding from automating data entry and normalizing documents is consistently large.

Accuracy and defensibility: Machines never tire on page 1,500. Doc Chat maintains consistent accuracy, surfaces every reference to coverage and dollars, and provides page-level citations so you can defend your conclusions to brokers, cedents, reinsurers, auditors, or regulators.

Portfolio clarity and pricing confidence: With normalized data, your portfolio views are reliable. You adjust terms and capacity based on each cedent’s true emergence behavior. Renewal conversations shift from opinions to facts, improving margins and lowering loss ratios over time.

Security, Governance, and Auditability by Design

Reinsurance involves sensitive policyholder and financial data. Nomad Data operates with rigorous security standards, including SOC 2 Type 2 controls referenced in our data entry overview. Every answer from Doc Chat links back to its source page, creating a clear, document-level audit trail that supports internal model governance, SOX-aligned controls, and regulatory inquiries. This explainability is exactly why claims organizations embraced Nomad for complex files—cited in our GAIG case study—and it translates directly to reinsurance due diligence.

Why Nomad Data Is the Best Choice for Reinsurance Underwriting Teams

Nomad Data’s Doc Chat is not generic OCR or a one-size-fits-all dashboard. It is a suite of purpose-built, AI-powered agents customized to your reinsurance workflows, documents, and standards. Core differentiators include:

• Volume at portfolio scale: Ingest entire submission folders—thousands of pages and rows—so reviews move from days to minutes.
• Complexity mastery: Doc Chat pulls exclusions, endorsements, and trigger language from dense, inconsistent documents and footnotes, enabling more accurate inferences about loss definitions and coverage impact.
• The Nomad Process: We train on your playbooks, cedent nuances, and preferred schemas, delivering a solution that mirrors how your team decides.
• Real-time Q&A: Ask “List all paid loss above attachment with sublimits triggered” and get instant answers with citations, even across massive document sets.
• Thorough and complete: Doc Chat surfaces every reference to coverage, liability, or damages equivalents in cedent documentation, minimizing leakage and misinterpretation.
• Your partner in AI: You gain a strategic partner who co-creates solutions with underwriting, actuarial, claims, and portfolio management, evolving with your needs.

Implementation is fast. Most reinsurers are live in one to two weeks, beginning with drag-and-drop pilots and progressing to workflow integrations—no heavy internal engineering required. As we describe in our implementation experiences, this low-friction path builds trust quickly and drives adoption across underwriting and risk teams.

Comparing Doc Chat to the Manual Status Quo

It is instructive to contrast Doc Chat with the old way. Manual teams spend their best weeks copying columns, reconciling footnotes, and debugging formulas. Doc Chat converts that same time into underwriting cycles: more submissions reviewed, deeper analytics per cedent, faster iteration on pricing and terms, and a tighter feedback loop with actuarial picks. The difference is not incremental speed; it is a step change in how your organization allocates scarce expertise toward value creation. That is the core thesis behind our claim processing transformation work and applies just as powerfully to reinsurance.

Key Use Cases Mapped to CUO Priorities

Renewal due diligence: Normalize all renewal loss runs and bordereaux for apples-to-apples comparisons, with automated red flags for data gaps or definition conflicts. Answer negotiation-grade questions instantly with citations.

Acquisitions and portfolio M&A: When assessing a book of business, automate the reading of every policy schedule and loss run, producing structured outputs that actuaries can triangulate immediately. See “AI for Insurance: Real-World AI Use Cases” for broader portfolio assessment patterns (“AI for Insurance: Real-World AI Use Cases Driving Transformation”).

Reserve and development monitoring: Build consistent triangles by cedent and line, track divergence to picks, and alert on late-reporting behavior or reopen spikes.

Counterparty risk and collectibility: Leverage Schedule F to validate cedent reporting and recoverables, highlighting aging concerns and helping prioritize credit risk actions.

Addressing Common Concerns About AI for Reinsurance Data

“Will the AI hallucinate fields?” In document-bounded extraction and normalization, large language models perform extremely well at identifying and aligning what is present. Doc Chat also provides page-level citations and confidence signals so every critical number is verifiable.

“Our cedents are all different.” Exactly why a custom agent matters. Doc Chat is trained on your playbooks and continuously learns from each new cedent and exception, so standardization improves over time.

“IT backlog will delay us.” Start with drag-and-drop pilots. Many reinsurers begin using Doc Chat in days, then integrate once value is proven. Typical integrations take one to two weeks thanks to modern APIs.

“We worry about data security.” Nomad adheres to enterprise-grade security and governance, with documented controls and transparent data lineage. Sensitive documents remain traceable end-to-end.

How to Get Started: A 2-Week Path to Value

Most CUOs want quick proof, not endless projects. Here is a standard onboarding motion that respects the urgency of renewal season:

1. Target a representative set: Select 5–10 cedents across lines with varied formats (PDF + Excel, different bordereaux layouts, and complex footnotes).
2. Define your schema: Provide your preferred output fields and any cedent-specific rules. We align Doc Chat to your taxonomy.
3. Run bulk ingestion: Drag-and-drop the submission packages. Within minutes, Doc Chat extracts, normalizes, and flags exceptions with citations.
4. Review and refine: Your team reviews exceptions while Doc Chat learns from corrections to reduce future flags.
5. Deliver insights: Export normalized data to pricing/reserving models and generate portfolio-ready analytics. Ask real-time questions to test negotiations.

By the end of week two, most teams have a fully operational pipeline for “bulk loss run data digitization for portfolio review,” with measurable cycle-time savings and higher underwriting confidence.

Where Doc Chat Fits in Your Reinsurance Stack

Doc Chat complements pricing models, actuarial tools, and exposure/cat platforms by solving the upstream document problem. It is the ingestion, understanding, and normalization layer that ensures downstream models run on consistent inputs. Whether you are pricing casualty XOL or evaluating a quota share roll, Doc Chat feeds clean data into your existing decisions. And because it retains document context and citations, it also strengthens audit and model governance processes.

Real-World Proof Points from Adjacent Insurance Workflows

Across claims, underwriting, and legal document review, insurers have proven that purpose-built AI is the only scalable answer to document chaos. Our “GAIG webinar replay” highlights how adjusters moved from days of scrolling to instant answers with page-cited outputs—a paradigm equally relevant to reinsurance submissions. In “Reimagining Claims Processing,” we document how cycle time can shrink by orders of magnitude when document review turns into question-driven discovery. And in “Beyond Extraction,” we explain why true value requires inference—exactly what reinsurers need to reconcile cedent definition drift and footnote-driven nuances.

Tie It Together: A CUO’s Checklist for Portfolio-Ready Loss Data

Before the next renewal cycle, align your team on a simple standard:

• Every cedent’s Loss Run Reports, Cedent Loss Bordereaux, Schedule F (NAIC), and Claim Register Exports are ingested and normalized automatically.
• All differences in definitions (ALAE vs. loss, gross vs. net, currency, claim reopen handling) are captured and cited.
• Triangle-ready outputs exist for accident and report year, by cedent and line, with development checks.
• Event mapping aligns to your standard catalog and reconciles to totals.
• Counterparty exposures and collectibility align to Schedule F evidence.
• Natural language Q&A delivers negotiation-grade answers instantly, with citations.

If any of these items still require days of manual effort, your team is running at a disadvantage when the market rewards speed and precision.
