Decommissioning liability results primarily from the partnership’s ownership interest in oil and natural gas wells and facilities, retail gas stations, a services provider to the offshore oil production industry and power generation services. The liability represents the estimated cost to reclaim and abandon the asset and takes into account the estimated timing of the cost to be incurred in future periods. The liability was determined using a risk rate between 1.6% and 8.5% (2018: 1.9% and 8.5%) and an inflation rate between 2.0% and 3.0% (2018: 1.9% and 3.0%), determined as appropriate for the underlying subsidiaries.
