1
Problem with early/traditional pricing procedures
(Feldblum)
used fixed UW profit provisions that became less credible & useful with time
2
Reasons to seek more accurate pricing models (3)
(Feldblum)
1. TVoM - pricing model should reflect timing & magnitude of CFs
2. competition and expected returns - price depends on degree of competition in the market
3. rate base - traditional profit margins are ROS, but ROE is more appropriate
3
Different POV for insurance transactions (2)
(Feldblum)
1. insurer and policyholder (focus in traditional ratemaking)
2. equity provider and insurer (focus in IRR model)
4
Insurer and policyholder view of insurance transactions (market, transaction, prices, and profits)
(Feldblum)
transactions occur in the product market
PH pays premiums and insurer is obligated to indemnify losses
prices are influenced by supply & demand of insurance
profits are only related to premiums & losses
5
Equity provider and insurer view of insurance transactions (market, transaction, return, and profits)
(Feldblum)
transactions occur in the financial market
shareholders invest in insurer & receive a return on their investment
returns are driven by insurance risk
profits are related to assets/equity only and only consider premiums/losses/expenses to the extent they impact shareholder transactions
6
Relationship between different POV for insurance transactions (2)
(Feldblum)
1. supply of insurance depends on cost insurers pay to obtain capital & returns achievable by investors
2. expected returns in the financial market depend on insurance risk & consumer demand for insurance
7
Decision rule for the IRR model
(Feldblum)
accept opportunities where IRR > cost of capital
8
Internal rate of return (IRR)
(Feldblum)
IRR = rate of return needed to set PV(CFs) = 0
(alternatively to set PV(cash inflows) = PV(cash outflows))
9
Initial cash outflows at policy inception from equity-holder's viewpoint (2)
(Feldblum)
1. portion of premium is used to pay expenses (not invested)
2. surplus is committed
10
Surplus impacts on equity flows & IRR (2)
(Feldblum)
1. base/amount of surplus
2. timing of commitment
11
Timing of surplus commitment and tail length comparisons (2)
(Feldblum)
if surplus base is premium, no distinction b/w required surplus for long vs. short-tailed LOB
if surplus base is reserves, long-tailed LOB require more surplus compared to short-tailed LOB (b/c surplus is committed for a longer amount of time)
12
General relationship between surplus and IRR
(Feldblum)
increase in required surplus reduces IRR
13
Equity CFs at time 0 (5)
(Feldblum)
1. PH pays premium to insurer
2. insurer pays expenses
3. insurer posts reserves
4. insurer commits surplus
5. equity holders pay insurer to cover shortfall
14
Equity CFs after time 0 (5)
(Feldblum)
1. insurer collects investment income
2. insurer pays losses
3. insurer reduces reserves
4. insurer releases surplus
5. excess returns are returned to equity holders
15
Initial loss reserves
(Feldblum)
initial loss reserves = expected losses
16
Required surplus at time t
(Feldblum)
required surplus(t) = loss reserve(t) / (reserve / surplus)
17
Required assets at time t
(Feldblum)
required assets(t) = required surplus(t) + loss reserve(t)
18
Ending assets at time t
(Feldblum)
ending assets(t) = required assets(t)
19
Equity flow (EF) at time t from insurer's and equity holder's POV
(Feldblum)
EF(t) = required assets(t) + payments(t) - beginning assets(t)
from shareholder's POV = - EF(t) from insurer's POV
20
Base options for surplus allocations for IRR model (2)
(Feldblum)
1. premiums
2. reserves
21
Timing of surplus commitment and surplus allocation base (2)
(Feldblum)
1. premiums - surplus is committed at policy inception and released at expiration
2. reserves - surplus is committed when losses occur or when UPR established and released as losses are paid
22
Steady state reserves
(Feldblum)
reserves at any point in time in a steady state environment
SS reserves = WP * LR * average time from loss to payment
23
Risks surplus protects the insurer against (7)
(Feldblum)
1. asset risk
2. pricing risk
3. reserving risk
4. asset-liability mismatch risk
5. catastrophe risk
6. reinsurance risk
7. credit risk
24
Asset risk
(Feldblum)
risk that financial assets depreciate
25
Pricing risk
(Feldblum)
risk that losses and expenses > expected
26
Reserving risk
(Feldblum)
risk that reserves may not be enough to cover ultimate loss payments
27
Asset-liability mismatch risk
(Feldblum)
risk that changes in interest rates impact assets and liabilities differently
28
Catastrophe risk
(Feldblum)
risk that unforeseen losses depress insurer returns
29
Reinsurance risk
(Feldblum)
risk that reinsurance recoverables will not be collected
