Underwriting practice, risk assessment and pricing fundamentals

Underwriting practice, risk assessment and pricing fundamentals

This domain tests how underwriters gather information, measure exposure, set terms and price risk, and how authority and governance constrain those decisions.

Information and assessment

Underwriters rely on proposal information, surveys, loss histories, financial data and, for catastrophe-exposed business, modelling. Key measures include sum insured, estimated maximum loss (EML), probable maximum loss (PML) and maximum foreseeable loss (MFL), plus accumulation control across the portfolio.

Pricing

  • Rate is a percentage of the sum insured or limit; premium = rate × exposure base.
  • Technical (or risk) rate reflects expected loss, expenses and profit; the market rate reflects supply and demand and may sit below technical rate.
  • Rate on line applies to reinsurance-style layers; burning cost derives from historical loss experience.
  • Terms shape price: deductibles, warranties, exclusions, limits and aggregate structures.

Authority, governance and contract certainty

Underwriters work within written authority limits (class, line size, territory). Files must evidence the reasoning - "file underwriting" - with peer review for larger or complex risks. Contract certainty requires complete, agreed wording at or before binding.

Worked example. A warehouse is offered at £50m sum insured, rate 0.25%, giving £125,000 premium. The underwriter's PML modelling suggests a 1-in-200 loss of £30m, against a £20m net capacity appetite. Options: increase the deductible, restrict cat cover, co-insure, or reduce the line to 40% at £20m. Pricing alone does not solve an exposure problem - capacity discipline does.

Traps. Using sum insured as a proxy for PML. Confusing EML with MFL (MFL assumes worst-case failure of protections). Confusing rate with premium. Ignoring the effect of deductibles and aggregates on the effective price. Binding before wording is agreed, undermining contract certainty.

Key points

  • Rate × exposure base = premium; rate is not premium.
  • Technical rate reflects loss cost, expenses and profit; market rate reflects competition.
  • PML, EML and MFL measure different loss scenarios and drive capacity decisions.
  • Underwriters work within written authorities with file evidence and peer review.
  • Contract certainty means agreed wording at or before binding.
