Layering Reinsurance Example
The Safe Insurance Company (SIC) writes
homeowners insurance in Florida. It specializes
in large expensive homes. Assume that the amount
of insurance on each home is 1000000.
Summary of SICs Exposures

• SIC has the following reinsurance program in
  place for its homeowners business in Florida
• A surplus share reinsurance treaty with Reinsurer
  A in which SIC retains the first 250000 of
  losses on each home and Reinsurer A assumes any
  losses exceeding 250000 up to a limit of
  1000000 on each home.
• A per occurrence excess-of-loss reinsurance
  treaty with Reinsurer B with a 100 million
  retention by SIC and a limit of 400 million.

15
Layering Reinsurance Example cont.
A severe hurricane strikes Broward Dade County
and Palm Beach counties causing insured losses
equal to 40 of total insured exposures in each
county. Assume that 40 of the homes insured by
SIC are totally destroyed but there are no losses
on the other homes insured by SIC. The table
below indicates the amount of losses suffered by
SIC on a direct (before reinsurance) basis.
16
Layering Reinsurance Example cont.

• How much will Reinsurer A pay to SIC according to
  its reinsurance contract
• How much will Reinsurer B pay to SIC according to
  its reinsurance contract
• What will be the amount of losses that SIC will
  retain after it is paid by its reinsurers

Factors Determining Reinsurance Needs
20
Setting Retentions

• Depends on purpose and type of reinsurance.
• Pro rata treaties for surplus relief will depend
  on premiums ceded ceding commission.
• Retention in excess of loss treaties for
  stabilizing experience depends on the size of
  loss insurer can absorb without undue effects on
  surplus or loss ratio.
• Most states limit maximum possible loss on any
  one exposure to 10 of surplus.
• Retain that which is stable and predictable and
  cede that which is not stable and predictable.
• Treaties should be integrated.

21
Setting Reinsurance Limits

• Ideally should cover most of the loss
  exposures of the primary insurer.
• Insurer may have target Prob. Max Loss (PML)
• Balancing protection against its cost.
• Higher layers require higher risk premiums.

  to share profits and risk.

• Modeled expected loss p

23
