Hands-on drills for Lesson 1 — From gross to net. Each runs on the canonical 2025 loss book of Alpina Versicherung AG and turns the lesson's one rule — net = gross + ceded, with ceded stored negative — into something you can drive to all-✓ yourself. Start easy by predicting nets; end by specifying a treaty whose rules interact. Every workbench ships red; your job is to make it green.
- 🟢 Easy · Predict the net — seven claims, seven nets. The naïve guess adds the cession; the sign rule subtracts it. Predict each net, run, and pin every surprise.
- 🟡 Medium · Build the cession — three facultative certificates, an empty
Cedefunction, and a check battery on every claim and both totals. Fill the stub until it all goes green. - 🔴 Hard · Spec the treaty — a per-risk treaty specified only in prose, with two nasty interactions: a flat cession that can't exceed the claim, and an attritional bulk it can't touch. Write the battery first, then the treaty.
