ALTAM: Show the model, not only the final spreadsheet number
For a long-term calculation, a reviewable answer identifies time, state, probability, discounting and cash flow. A correct total with unexplained formulas is hard to check. Practise organising a small model before relying on a large spreadsheet.
Worked example or practice scenario
Use one row per year with opening lives, survival or decrement assumptions, premium, expense, benefit, discount factor and present value. Run a simple boundary test: no mortality, no lapse and zero interest. The output should reduce to the explicitly scheduled cash flows.
Try this next
Then introduce one assumption at a time and explain the direction of change. When preparing for a sitting, use the current official tools and instructions; do not infer spreadsheet permissions from an old forum post.
