Inventories consist of natural gas (in excess of the “Line Pack” classified as property, plant and equipment) in the Company’s pipeline system, and the liquids stored obtained from natural gas processing at the Cerri Complex.
Inventories are measured at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of inventories includes expenditure incurred in purchasing and production and other necessary costs to bring them to their existing location and condition.
The net realizable value is the estimated selling price in the ordinary course of business less the estimated cost of completion and the estimated costs to make the sale.
The assessment of the recoverable value of these assets is made at each reporting date, and the resulting loss is recognized in the statement of comprehensive income when the inventories are overstated.
