Revenue from contracts with customers – according to IFRS 15 – is recognized when control of the goods or services is transferred to the customer at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services.

The Group generates revenues from sale of logs and sawn timber products and recognizes the revenue at a point in time when the goods are at the point the customer purchases them. Payment of the transaction price is due immediately at the point the customer purchases the goods, or within 30 days for account holding customers. For international sales the Group recognizes the revenue for goods at a point in time, according to the agreed Incoterms (International Commercial Terms).

MIL Energia Renovável (former BK Energia Itacoatiara) – a subsidiary of Precious Woods – generates electricity and CERs (Certified Emission Reductions) with its biomass power plant in the Amazon region of Brazil. The electricity produced is fed into the regional state electricity grid and measured on a monthly basis. The revenue is recognized at that point in time. Payment of the transaction is due within 30 days by the grid owner. The CERs are purchased by Precious Woods Holding. The produced CERs are recognized as inventory and valued at the lower of cost or net realizable value as long as the certification is not yet achieved, and sold afterwards.
