Step 1: Split the product in two
InsuranceFund
Policyholderfund
Premiums
Return of fund ondeath or surrender
Risk chargesExpense charges
MER/spreadSurrender charges
Net death benefit(face value)
ReinsurancePremiums Benefits
Expenses
Taxes
Step 2: Match the policyholder fund
• For index linked accounts, buy the underlying index• Track liability balances on at least a weekly basis• Compare asset returns with index returns and
identify sources of tracking error– asset/liability mismatch– transaction costs– backdating– tracking of assets to index (i.e. exchange traded funds,
index futures)– tax effects
Step 3: Match the insurance fund (the hard part)
Reserve components of a typical UL policy:
Present value Duration
Risk charges 6,488,404 10
Net benefits (4,881,908) 21
Ceded premiums (2,157,152) 20
Ceded benefits 2,435,406 19
Expense charges 693,615 10
Expenses (566,236) ??
Surrender charges 248,522 ??
Commissions (1,641,296) 2
Investment income tax (455,153) ??
Crediting rate margin 304,609 ??
Net total 468,811
Note: figures vary (a lot) depending on age of policyholder, age of policy, policy features, fund types, MER levels, modeling assumptions.
If interest rates fall 1%
Present value
Risk charges 6,488,404 7,163,944
Net benefits (4,881,908) (6,475,137)
Net 1,606,496 688,807
A 1% rate decline removes $917,689 worth of profitability from the line of business. Reserves will increase by roughly this amount.
The largest risk is in the risk (COI) charge vs. net benefit cash flows

1. “Sell” this cash flow to annuities.
2. Sell the asset that the inter-segment note replaces and transfer the cash from Annuities to Universal Life
$
3. Use the cash to buy long-dated assets that better match the liability profile.
Other cash flow components• Ceded cash flows
– premiums and benefits usually have similar durations– small positive cash flow (pricing vs. reserving assumptions)– long duration – offsets some death benefit cash flows
• Expense charges– generally fixed – same duration as premiums
• Expenses– interest rate theoretically = inflation + real interest rate– higher interest rates => higher inflation– theoretical duration is zero– how does valuation model treat inflation?
• Surrender charges– short term (generally 5 years or less)– surrenders (fund depletion) fall when interest rates rise
“Problem” cash flow components• Crediting rate margin
– depends on fund size => higher fund returns mean larger
fund and more crediting rate cash flows– when equity markets fall, future MER cash flows decline too– movement from equity linked to GICs reduces MERs– in high-return scenarios, fewer policies lapse– effective duration very sensitive to model assumptions and can
only be determined through scenario testing– do you believe the current 2-3% MERs will hold up for 40 years?
• Investment income tax– based on a 5-year moving average of 10-year Cda bond yields– you have to pay IIT even if equity returns are negative
• Expenses– interest rate theoretically = inflation + real interest rate
Summary• UL is far more complicated than most other insurance products – interest rate risk is potentially huge.• Cash flow dynamics are complex, and don’t depend only on interest rates. Duration (including key rate duration) is not sufficient.• Assumptions (including policyholder behavior) have a large impact on cash flow dynamics (and reserves).• You need a well thought out model.• You need to understand the valuation software well enough to be sure it is implementing the model correctly.• You need to sensitivity test the key assumptions.
