Revenue recognition
The company enters into contracts for the sale of gold. Revenue arising from gold sales under these contracts is recognized when the price is determinable, the product has been delivered in accordance with the terms of the contract, the significant risks and rewards of ownership have been transferred to the customer and collection of the sales price is reasonably assured. These criteria are met when the gold leaves the mines’ smelt houses. As sales from gold contracts are subject to customer survey adjustment, sales are initially recorded on a provisional basis using the group’s best estimate of the contained metal. Subsequent adjustments are recorded in revenue to take into account final assay and weight certificates from the refinery, if different from the initial certificates. The differences between the estimated and actual contained gold have historically not been significant.
