Assessment and review

Margin assessment

To achieve the desired margin coverage, the risk interval is set to minimum the higher of one-day or two-day price movements based on historical data. Price movements from the last 500 business days are included in the analysis, but price movements further back in time than the last 60 business days carry lower weight.

The risk interval is reviewed at least every second month. Ad hoc reviews occur when a risk interval is challenged or exceeded or when an unexpected event is announced (or become apparent) between reviews (for example, weather conditions affecting certain freight routes).

The reviews are published in the Margin Notices section.
