What is a parametric solution?

  • Parametric insurance programmes respond to movements in an index or the occurrence of a pre-agreed event, such as extreme weather
  • Claims are triggered if:
    • The actual measurement of the index during the contract period moves above (or below) an agreed index point, or
    • The physical characteristics of the event meet pre-agreed criteria (e.g. intensity and location)
  • The claim amount is calculated according to a pre-agreed scale of payment, not by reference to actual loss, damage or concept of indemnity
  • Claims are paid quickly after the occurrence of the policy trigger
  • There is no restriction on the use of claims payments

Weather exposure by industry

In recent years the global climate has become increasingly volatile and unpredictable, as evidenced by unusual and unseasonable weather.

For many organisations, weather affects the volume of sales and/or costs and expenses, creating volatility of profits and financial results.

In some sectors, such as energy, there is a very clear relationship between the volume of sales and the weather. In fact, statistically, the correlation between the sales of gas and aggregate measures of temperature may exceed 90%.

But this clear correlation between weather and revenues is not just limited to energy companies. The table below shows some of the better-known effects of adverse weather within certain industry sectors. There are many others.

Industry Weather exposure
Real Estate Severe winters increase energy bills, maintenance and snow removal costs
Construction Excessive rain, wind or snow delays projects resulting in liquidated damages
Food and Agriculture Drought, frost or extreme heat damages crops or reduces yields
Leisure and Hospitality Excessive rain, cold, or snow forces cancellation or reduces attendance
Natural Resources Excessive rain causes shut down of mines
Power Utilities Warm winters reduce energy demand
Public Authorities Severe winters increase snow removal and road gritting costs
Renewable Energy Lack of consistent wind, water or solar energy reduces power generation and thus revenue
Retail Excessive rain or snow reduces footfall and unseasonal weather reduces demand for seasonally sensitive ranges
Transport and Logistics Excess snow or extreme cold causes flight delays and cancellations
Water Utilities Low rainfall results in water shortages 'Freeze-thaw' events can lead to massive disruption and costs
