f. Receivables

Trade receivables are amounts due from customers for coal and electricity sold or services performed in the ordinary course of business. Non-trade receivables are amount arising from transactions outside of the ordinary course of business. If collection of the receivables is expected in one year or less, they are classified as current assets. If not, they are presented as non-current assets. Receivables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method, if the impact of discounting is significant, less provision for impairment. Non-trade receivables to related parties are initially presented as non-current asset unless there are specific reasons for them to be presented as current assets in the consolidated statements of financial position. 163 AdARo ENERgy 2014 ANNuAl REPoRT PT ADARO ENERGY Tbk AND SUBSIDIARIES Schedule 512 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 31 DECEMBER 2014 AND 2013 Expressed in thousands of US Dollars, unless otherwise stated

g. Inventories Coal inventories are stated at the lower of cost or net realisable value. Cost is determined based on the weighted average method which includes mining costs, direct labor costs, other direct costs and an appropriate portion of fixed and variable overheads related to mining operations. It excludes borrowing costs. The net realisable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale. Spare parts, fuel, lubricants, tools and supplies are valued at cost less a provision for obsolete and slow moving inventory. Cost is determined based on the weighted average method. A provision for obsolete and slow moving inventory is determined on the basis of estimated future usage or sale of individual inventory items. Supplies of maintenance materials are charged to production costs in the period in which they are used.
