Company B is a major European gas distributor with a large weather exposure in France. Its revenues are badly affected by warm winters, which result in lower demand from its customers. It is looking to hedge against a lack of Heating Degree Days during the winter months in Paris.
A Heating Degree Day (HDD) is a measure widely used by energy companies and is equal, for any given day, to the difference between 18°C and the average temperature for that day (only if the temperature is below 18°C). The total number of HDDs over the winter is therefore a good measure of heating requirements for its customers.

This Weather Derivative covers Company B against warm winters (i.e less than 1,700 HDDs) in Paris.
If there are a total of 1,649 HDDs in the Risk Period Company B would receive: (1,700 – 1,649) x 5,000 = EUR 255,000.
The payment, if there is any, normally occurs 5 business days after the end of the Risk Period (subject to data availability).
