Agenda
1. Brief overview of the new China GAAP
2. Modeling Challenges
3. Results of an informal survey
4. Looking ahead: IFRS 4 Phase 2 modeling challenges
5. Efficient modeling suggestions
Key Computational Components
Best estimate liability
Gross premium reserve
Best estimate assumptions
Risk margin
Currently handled as margins in risk factors
Residual margin
Amortized time zero profit
Modeling Challenges
How do you prove assumptions are reasonable?
Assumptions need to be audited
Can show experience study
Can the assumption reasonably reproduce cash flow?
Dynamic fit is a back casting technique
Prove that in the year past, cash flows are reasonably reproduced by
model using assumptions
Not easy to implement
Modeling Challenges
How to handle risk margin (风险边际)?
Needs two-pass projection
Run the model twice and subtract?
Fine for time zero valuation
Can be impractical for projection of balance sheet
Modeling Challenges
How to handle residual margin (剩余边际)?
Method 1: locked amortization ratio
Easy
Method 2: keep time zero balance, unlock amortization ratio
Should be no problem for most commercial software
Method 3: unlock both time zero balance and amortization ratio
Should be no problem for most commercial software
Possibly Method 4? : Same as Method 3, but keep historical actual
amortization base. A US GAAP approach to DAC
Messy, have to keep historical amortization base in a file
