Mathematicians / Statisticians have been affected by the radical transformation of the energy markets. Procurement processes and business transactions have become extremely complex and are defined increasingly by the power exchanges. A strong background in mathematics and statistics is therefore required for making the necessary optimisations to these processes. Statistics-based tasks in the energy sector include complex options pricing, demand forecasts, weather data and stock market developments. Because of this environment, energy companies have a diverse range of resources for modelling their energy purchases at their disposal. The most effective procurement mix is identified using selection processes based on individual mathematical optimisation models.

Credit risk analysts are responsible for analysing credit risk, structuring and ratings, and even for project finance when applications are received from large clients. They also study and assess financial models in existing balance sheet analyses, conduct their own risk analyses making recommendations directly to decision-makers and formulate credit conditions based on risk. They also check, record and process waiver requests and develop risk handbooks and risk management processes on a continuous basis.

Actuaries compile balance sheets for investment and risk associations and are responsible for forecasting and financial modelling, as well as calculating premiums and claims. They also offer support to specialist sectors on current issues relating to insurance.
