IFRS 17 in year three: what insurance audit committees still get wrong.
Three reporting cycles in, IFRS 17 has stopped being a project and started being routine. Which is exactly when the disclosure errors and measurement-model misses become the audit-committee’s problem, not the project team’s.
By year three, IFRS 17 has stopped being a programme of work and started being how insurers report. That is the moment when the project team has been disbanded, the model has been validated once, and the audit committee assumes the work is done.
It rarely is.
Measurement-model drift
The Premium Allocation Approach (PAA) was selected by most Tanzanian short-tail non-life insurers at transition, on the grounds of eligibility and operational simplicity. Three years on, several portfolios have grown long-tail tails, particularly motor-bodily-injury and medical malpractice, and the PAA eligibility test has not been re-run.
"Year-one disclosure was conservative because the project team didn't yet trust the model. Year-three disclosure tends to be conservative for a different reason, nobody is checking."
Transition disclosure stickiness
Transition disclosures designed for the year-of-transition narrative are still being produced. Audit committees should ask whether the disclosure inventory has been re-scoped to year-three relevance, or whether the report is still describing the journey rather than the position.
Regulator expectations have moved
TIRA’s thematic reviews are now audit-committee-level. Where year-one focused on transition mechanics, year-three reviews are on disclosure adequacy, profitability-by-cohort visibility, and the consistency between IFRS 17 results and the prudential-return numbers.
- Re-confirm PAA eligibility annually, not just at transition.
- Ask for an explicit reconciliation between IFRS 17 reported results and TIRA prudential returns.
- Check that disclosure inventory matches year-three relevance, not transition narrative.
- Make sure profitability-by-cohort is presented to the committee, not just to the board.
