Setting up

If the claims history carries dates, the triangle is already there to build.

1. Create a study

Choose the valuation date, the classes, year or quarter, and paid or incurred.

2. Build the triangle and select factors

Build it, read the three factor methods, overrule where your judgement differs, and re-project.

3. Sign the reserves

Read ultimate and IBNR by origin year; the appointed actuary signs the study.

4. Measure under IFRS 17

Point the half-year measurement at the study, measure, check that it explains itself, and have the appointed actuary sign.
