This is not a course about reinsurance in general — it is training for the MeshWeaver reinsurance suite as deployed. Every lesson opens in the product's own screens, on the installed demo book, and every exercise changes one real thing and watches the system react.
The operating goal you are training toward
The suite is built for straight-through processing: about 80% of items should pass without manual modification — renewal submissions auto-decided within delegated authority, bordereau lines auto-reconciling ✅, agent drafts accepted as-is.
And you get there by iterating the texts — the guideline rules, the reconciliation tolerances, the briefs and enquiry templates — not by adding manual steps. Three lessons each run one full turn of that loop (measure the pass rate, adjust the text, measure again):
Who this is for
Underwriters, claims analysts and underwriting assistants joining a desk that runs on the MeshWeaver reinsurance suite — and the engineers and consultants who configure it for them.
- You should know what an excess-of-loss layer is and how a cession splits a loss. The arithmetic itself is the prerequisite course, Basic Risk Transfer.
- No programming background is required — the live code cells are there to be read and run.
- Every product change is shown click by click (or prompt by prompt, in the chat).
What you'll be able to do at the end
- Read a renewal submission critically in the product — tower, economics, bordereau, stored status
- Trace any compliance verdict to the rulebook data node that produced it, and change that node deliberately
- Say who may sign a given placement, and why — and flip a referral by moving one authority rung
- Watch a capacity-cap breach appear and clear as the offered line moves
- Read and write a decision record whose governance rules actually gate the bind
- Work a claim's append-only development history — and never overwrite it
- Run the bordereau reconciliation, read all four verdicts, and flip one with a single product edit
- Compute the recovery a treaty owes on a gross loss, reinstatement premium included
- Drive the product's chat: ask it to show any area, and to adjust parameters conversationally
Before you start
- Basic Risk Transfer — the cession arithmetic this course leans on (one formula is restated in Lesson 11, the rest is assumed).
- Setup — which modules must be installed on your mesh and how to import the demo book. The walkthroughs work read-only on any mesh that serves the demo; the change-one-thing exercises need an installation you may write to.
How each lesson works
| Band | What it is |
|---|---|
| 🧭 In the product | The concrete click path from the dashboard to the screen this lesson lives on — plus the guided tour stop where one exists. |
| 📖 Theory | What the product computes and why, kept short, with the real rulebook clauses and record shapes. |
| ⚡ Experience it | A live code cell reproducing the product's calculation on the same numbers — read it, run it, change it. |
| ✍️ Your turn | Three graded exercises. The 🟡 one usually changes one item in the installed product and watches the system react. |
The syllabus
Part 1 — Underwriting the treaty year (the underwriting desk)
- The submission — what arrives at renewal, read critically
- The rulebook as data — guidelines as typed rules, and the STP loop
- Authority and referral — who may sign what
- Capacity and aggregation — caps, the book, correlated exposure
- The decision — verdict, share action, governance
- The renewal book — the register, hit ratios, walking away
Part 2 — Claims and recoveries (the claims desk)
- The claim record — append-only development history
- Development — how claims move between evaluations
- The bordereau — the cedent's loss statement
- Reconciliation — four verdicts, and what each triggers
- Cession and recovery — gross claim to treaty recovery
- Closing the year — enquiries, audit trail, the year-end position
The worked book
Everything runs on the suite's installed demo book — and every number in the lessons, exercises and quizzes reconciles to that one book.
- The programme — Meridian Re's MTPL cover for cedent Alpina Versicherung AG (St. Gallen; its German motor branch writes MTPL in EUR), placed by Cartwright Re.
- The year under way — the bound 2026 treaty and the 2027 renewal under assessment, with five claims carrying real development histories.
- The renewal bordereau — whose reconciliation tells all four verdict stories.
- Alpina's wider book — Marine XL, Casualty XL, per-Risk, a declined run-off.
- Two comparison placements, in the course's own cells — Mistral Assurances Mutuelles (FR) and Léman Assurances SA (Lausanne).
