We were speakers at Annual Meeting of the Institue of Actuaries of Japan. We presented challenges, insights and solutions.

1. The design of the IFRS 17 actuarial process.

2. Goal of presentation
Present insights and useful ideas
Share my experience in designing
IFRS 17actuarial processes
Indicate challenges and possible
solutions

The focus will be on what actuarial model must
produce to deliver data required by subledger.

3. AoC required
4actuaries.com, presentation for the Institute of Actuaries of Japan
Aoc Step Description
1 Beginning of Period/Expected
2 Change in non-financial risks
3 Change in financial risks
4 Change in discretion
5 New Business
6 End of period (change in FX)
We assume there are 6 steps of minimum AoC:
Expected step is the same step as Beginning of
Period but values are read from time step 1 not 0.

4. Data requirements
We divide it into the following groups:
a) Expected cashflows from previous period
b) Coverage Units (“CU”) at Beginning of the Period (“BoP”) and at the End of the Period (“EoP”)
c) Best Estimate of Liabilities (“BEL”) for different steps of Analysis of Change (“AoC”) at locked rates (“@LR”) & at
current rates (“@CR”)
d) Risk Adjustment (“RA”) for different steps of AoC
e) Liability of Incurred Claims (“LFIC”) for different steps of AoC split between Best Estimate (“BE”) and RA
component
f) Time Value of Option and Guarantees at Beginning of the Period (“BoP”) and at the End of the Period (“EoP”)
g) Actual Cashflows in the period
h) Book Values (“BV”) and Market Values (“MV”) of assets and investment income in the period
i) Equity positions: Share Premium, Share Capital etc.
The position g), h) and i) are delivered by accounting department so here we will just explain at which stage this data
shall be provided in the process.

7. IFRS 17 profitability bucketing requirement
NSPO*
Other
Onerous
NSPO* - No Significant Probability of becoming Onerous
It should be reliable but at the
same time as easy as possible to
implement
There is no specific requirement
on the algorithm

10. IFRS 17 profitability bucketing in practice
This is the algorithm of the method we implemented to our clients:
The functionality works as follows:
Step 1. Calculate BEL(𝐵𝐸𝐿), PV of Benefits (PVBen), and PV of Expenses (PVExp )
Step 2. PV of Cashflows after sensitivity 1 as follows:
𝐵𝐸𝐿𝑠𝑒𝑛𝑠𝑖1 = 𝐵𝐸𝐿 − PVBen + PVBen ∗ 𝐵𝑒𝑛𝑆𝑒𝑛𝑠𝑖1 − PVExp + PVExp ∗ 𝐸𝑥𝑝𝑆𝑒𝑛𝑠𝑖1
Step 3. PV of Cashflows after sensitivity 2 as follows:
𝐵𝐸𝐿𝑠𝑒𝑛𝑠𝑖2 = 𝐵𝐸𝐿 − PVBen + PVBen ∗ 𝐵𝑒𝑛𝑆𝑒𝑛𝑠𝑖2 − PVExp + PVExp ∗ 𝐸𝑥𝑝𝑆𝑒𝑛𝑠𝑖2
Condition Profitability bucket
𝐵𝐸𝐿 ≥ 0 𝑜𝑟 𝐵𝐸𝐿𝑠𝑒𝑛𝑠𝑖1 ≥ 0 Onerous
𝐵𝐸𝐿𝑠𝑒𝑛𝑠𝑖1 < 0 𝑎𝑛𝑑 𝐵𝐸𝐿𝑠𝑒𝑛𝑠𝑖2 ≥ 0 Other
𝐵𝐸𝐿𝑠𝑒𝑛𝑠𝑖2 < 0 NSPO
Step 4. Allocate to profitability buckets as follows:

15. Risk Adjustment disclose confidence level
This is the algorithm of the method we implemented to our clients:
The confidence level must
be a multi-year confidence
level, not a yearly one as for
SII
SII 99.5%
yearly
Not satisfying IFRS
17 requirement!
Formula: 𝐶𝐿𝑛−𝑦𝑒𝑎𝑟𝑙𝑦 = 1 − (𝑛 ∗ 1 − 𝐶𝐿𝑦𝑒𝑎𝑟𝑙𝑦 )
for n = 40 & 𝐶𝐿𝑦𝑒𝑎𝑟𝑙𝑦 = 99.5%→𝐶𝐿𝑛−𝑦𝑒𝑎𝑟𝑙𝑦 = 1 − (40 ∗ 1 − 0.995) = 80%
