Spotting Coverage Triggers in Complex Multi-Layer Reinsurance Towers (Reinsurance, General Liability & Construction) - Treaty Structurer

Spotting Coverage Triggers in Complex Multi-Layer Reinsurance Towers (Reinsurance, General Liability & Construction) - Treaty Structurer
Multi‑layer reinsurance towers for General Liability and Construction risks are designed to distribute severe loss volatility across layers, participants, and years. But when a claim hits, the speed and accuracy with which you find the precise trigger language and attachment points can make or break outcomes. For a Treaty Structurer, the core challenge is locating and reconciling the exact words—across binders, slip policies, endorsements, and negotiation redlines—that determine when, how, and where each layer attaches and responds. Ambiguity, non‑concurrency, and sheer document volume slow settlements and elevate leakage risk.
Doc Chat by Nomad Data removes that bottleneck. Purpose‑built for insurance document intelligence, Doc Chat for Insurance ingests entire tower files—Layered Treaty Diagrams, Trigger Schedules, Attachment Point Tables, endorsements, bordereaux, FNOLs, and claim correspondence—and instantly answers questions like: “Where is the per‑occurrence trigger defined for the excess of $25M xs $25M layer?” or “List all attachment points and aggregates by policy year and layer.” The result: faster, defensible coverage decisions and cleaner claim paths through complex towers.
The Treaty Structurer’s Reality in Reinsurance and GL & Construction Towers
In casualty and construction lines, towers often span multiple layers with different reinsurers, percentages, and sometimes subtly different terms. A single tower might include primary, buffer excess, lead excess, and multiple following layers, with potential side‑by‑side aggregates, annual aggregates, or clash or catastrophe‑type features layered in. For Treaty Structurers, the job is to build and maintain towers with maximum concurrency and minimum ambiguity—then prove intent and application when claims arrive months or years later.
Complicating matters further:
- Trigger heterogeneity: “Losses Occurring During” (LOD/LOD), claims‑made, manifestation, continuous trigger (for construction defect), or “as per original” provisions that follow underlying CGL/OCIP/CCIP wording—each with bespoke endorsements that can diverge layer by layer.
- Definitions that drive outcomes: What is “Ultimate Net Loss”? What constitutes “any one Occurrence”? How do batch/related‑acts or “interrelated wrongful acts” analogs apply to GL & construction claims (e.g., product defect or project‑wide water intrusion)?
- Drop‑down and exhaustion mechanics: Does an underlying aggregate exhaustion trigger a drop‑down? Does the excess layer require underlying insurer payment or simply underlying limit exhaustion? Are there cut‑through or follow‑form nuances?
- Construction program overlays: Additional insured endorsements, completed operations periods, wrap‑ups (OCIP/CCIP), joint venture agreements, indemnity agreements, and subcontractor exclusions must align with tower triggers—yet are often documented outside the treaty folder.
- Endorsement drift and non‑concurrency: The lead’s intent may not match following market endorsements. Mid‑term endorsements (MTEs) can change trigger language, reinstatements, or aggregates for only part of the tower.
When a claim advices, Treaty Structurers and their claims partners must quickly determine whether tower triggers are met and which layer attaches, taking into account policy years, aggregates, SIR/deductibles, completed ops, additional insured status, and any relevant subjectivities. Doing that work correctly—and with page‑level evidence—requires comprehensive, precise document analysis.
How the Process Is Handled Manually Today
Most Treaty Structurers still rely on a patchwork of manual tools and institutional knowledge:
- Scrolling through PDFs of Layered Treaty Diagrams, Trigger Schedules, Attachment Point Tables, slip policies, binders, and the final treaty wordings.
- Cross‑referencing expired and current endorsements, side letters, broker cover notes, and subjectivities.
- Mapping definitions and triggers into Excel trackers to build a single source of truth for attachment points, aggregates, reinstatements, and hours/batch clauses.
- Comparing treaties against underlying CGL or project policies, wrap manuals, additional insured endorsements, and indemnity contracts to ensure “as per original” truly follows form.
- For claims, reconciling FNOL forms, bordereaux, loss advices, ISO claim reports, legal correspondence, demand letters, and internal claim summaries to determine whether and when the tower was triggered and what layer should respond.
These steps can take days for straightforward files and weeks for complex ones. Each reread risks introducing inconsistency; each handoff risks context loss. Even the best teams encounter version sprawl, ambiguous redlines, and missing context hidden in email threads or broker binders. The result is latency, leakage, and disputes that erode margins and relationships.
AI to Identify Trigger Language in Reinsurance Tower Docs
Doc Chat is designed to zero in on trigger mechanics across layered agreements at scale. It reads every page, every endorsement, and every appendix—then lets you ask precise, plain‑language questions with citations back to the source pages. For Treaty Structurers, that means you can instantly locate and compare how each layer defines:
- Occurrence, claims‑made, manifestation, continuous triggers, and “losses occurring during” constructs.
- Batch/related events clauses and any “any one loss” vs. “each and every loss” nuances.
- Exhaustion requirements: underlying payment vs. limit exhaustion, collateral use, or interim payments.
- Drop‑down conditions, cut‑through provisions, hours clause analogs (where present), and clash features.
- Follow‑form language, “follow the settlements,” ex gratia restrictions, and “as per original” scope.
Because Doc Chat is built for insurance inference—not just keyword spotting—it understands when a trigger is defined indirectly through cross‑references to definitions, endorsements, or underlying policies. This is the difference between merely “extracting” and truly “interpreting” documents, a distinction we explore in Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs. For Treaty Structurers, that means fewer blind spots and rapid alignment on what the contract actually says.
Extract Attachment Points from Multi‑Layer Treaties—Instantly and Defensibly
Attachment point accuracy underpins every settlement and recovery strategy. Doc Chat pulls attachment points and limits directly from Attachment Point Tables, slip lines, and treaty schedules, then reconciles them against the narrative wording and endorsements. It can generate a structured summary—by layer and policy year—of:
- Attachment and exhaustion points (per occurrence and/or aggregate).
- Sublimits and aggregates, including completed ops and products aggregates for GL & construction exposures.
- Reinstatement rights and premium calculations, including pro‑rata or fixed pricing methods.
- Currency and indexing references, with conversions where relevant.
- Follows‑form dependencies on underlying policy triggers and definitions of Ultimate Net Loss.
The output isn’t just a table—it’s a living, traceable map with page‑level citations. If a downstream dispute arises, you can click through from the extracted field to the exact page and clause used, providing the auditability your claims, legal, and reinsurance accounting teams require.
Analyze Layered Reinsurance Agreements with AI—Across Every Version
Layer concurrence is fragile. A small wording shift in a following layer endorsement can ripple into material non‑concurrency at the worst possible moment. Doc Chat compares versions and highlights divergences in trigger language, sublimits, aggregates, reporting requirements, and subjectivities across the entire tower. Treaty Structurers can then normalize language or document intentional differences and their implications before bind, or surface them instantly when a claim is notified.
For example, if the lead follows “losses occurring during the policy period” but a following layer tweaks the manifestation language tied to completed operations, Doc Chat will surface the difference and show you the relevant endorsements. If a mid‑term endorsement introduces a “batch event” treatment for a product recall, Doc Chat will flag the change and illustrate its interplay with “any one occurrence” limits and aggregates—before it becomes a live claim pain point.
Crosscheck Triggers in Reinsurance Claims—From FNOL to Settlement
Trigger disputes often arise when real‑world events cut across policy years, projects, and defendants. Construction defect is a classic example: water intrusion discovered post‑completion may implicate continuous injury triggers across multiple years and entities. For GL & construction towers, Doc Chat cross‑checks FNOL forms, claim notices, demand letters, defense counsel reports, and bordereaux against the tower’s Trigger Schedules and Attachment Point Tables, then answers:
- Which trigger applies based on the facts alleged and dates of loss/occurrence?
- Is the loss an occurrence or a batch/related series event, and which aggregate (if any) is impacted?
- Has the underlying aggregate or occurrence limit been exhausted, and does the excess require actual payment or merely limit exhaustion?
- Do completed operations, additional insured endorsements, or wrap‑up manuals alter how the tower follows original?
- Does an hours‑like or clash feature apply for multi‑claimant events?
These questions are no longer answered via best‑effort manual reading. They’re answered with precision and citations. That is how you “crosscheck triggers in reinsurance claims” at enterprise speed.
Document Types and Data Points Doc Chat Handles for Treaty Structurers
To deliver this level of accuracy and speed, Doc Chat reads and normalizes an expansive set of reinsurance and claims artifacts, including:
- Layered Treaty Diagrams, Trigger Schedules, and Attachment Point Tables
- Slip policies, binders, treaty wordings, lead and following market endorsements
- LMA/NMA clause schedules, subjectivities, lead follow‑form exhibits, cut‑throughs, and side letters
- Underlying policies and endorsements for CGL/OCIP/CCIP, additional insured endorsements, completed operations terms, indemnity agreements, and wrap manuals
- Loss run reports, bordereaux, FNOL forms, ISO claim reports, defense counsel summaries, medical reports, demand letters, and settlement agreements
- Reinstatement provisions and pricing mechanics (fixed, pro‑rata), annual aggregates and occurrence aggregates
- Retrocession summaries where relevant (to understand back‑to‑back trigger alignment)

Real‑World Scenarios Across GL & Construction Reinsurance
Scenario 1: Construction Defect—Continuous Injury and Completed Ops
A large project experiences water intrusion discovered two years post‑completion. The cedent reports multiple property damage allegations spanning construction and occupancy. The tower includes an OCIP with completed operations coverage and a multi‑layer reinsurance program. Doc Chat:
- Extracts and compares the tower’s triggers (LOD vs. manifestation vs. continuous) and the underlying policy’s completed operations language.
- Flags a discrepancy in a following market endorsement that narrows the manifestation clause versus the lead wording.
- Surfaces the drop‑down requirements and whether underlying payment is required for exhaustion.
- Outputs a coverage pathway with page citations to support the trigger selection and the layer attachment determination.
Scenario 2: Product Liability—Batch/Related Events and Aggregates
Multiple claimants allege bodily injury from a defective product. The cedent’s GL program rolls up numerous incidents potentially tied to a single defect across two policy periods. The tower includes an annual aggregate on the third excess layer. Doc Chat:
- Locates all batch/related events clause language across layers and highlights one follower’s more restrictive aggregation provision.
- Maps how aggregated occurrences impact annual aggregates and reinstatements on upper layers.
- Confirms whether the lead’s “follow the settlements” applies to aggregation decisions and whether ex gratia restrictions affect recoveries.
Scenario 3: Wrap‑Up Program—Additional Insured and Indemnity Interplay
A general contractor and multiple subs are named in a claim from a construction incident. The cedent relies on an OCIP and subcontract indemnity agreements. The reinsurance tower follows original per the lead. Doc Chat:
- Cross‑references OCIP manuals, additional insured endorsements, and indemnity language with the tower’s follow‑form provisions.
- Shows how the underlying’s additional insured status impacts insured vs. insured or cross‑liability clauses at the treaty level.
- Summarizes the attachment points and aggregates impacted if the loss triggers completed ops coverage.
Outputs You Can Use: Schedules, Spreadsheets, and System Feeds
Treaty Structurers need deliverables that plug directly into workflows:
- Trigger comparison matrix: Layer‑by‑layer side‑by‑side of occurrence/claims‑made/manifestation language with citations.
- Attachment & limit table: By policy year and layer, showing attachment, per‑occurrence and aggregate limits, reinstatements, and sublimits.
- Concurrency heatmap: Highlights where follower wordings diverge from lead terms on triggers, exhaustion, drop‑down, and follow‑form.
- Claim coverage pathway: Aligns FNOL facts to triggers and attachment, indicating which layer(s) respond and why.
- Export formats: Spreadsheets for underwriting and reinsurance accounting; JSON for claims systems and data lakes.
This is document intelligence coupled with operational practicality. For how this approach turns even “data entry” into strategic leverage, see AI’s Untapped Goldmine.
Security, Auditability, and Model Governance
