The following disclosure is from Note 5 of the 2013 financial statements for BMW Group, the German automaker:
Revenues from the sale of products are recognized when the risks and rewards of ownership of the goods are transferred to the dealer or customer, provided that the amount of revenue can be measured reliably, it is probable that the economic benefits associated with the transaction will flow to the entity and costs incurred or to be incurred in respect of the sale can be measured reliably. Revenues are stated net of settlement discount, bonuses, and rebates. Revenues also include lease rentals and interest income earned in conjunction with financial services. Revenues from leasing installments relate to operating leases and are recognized in the income statement on a straight-line basis over the relevant term of the lease. Interest income from finance leases and from customer and dealer financing are recognized using the effective interest method and reported as revenues within the line item “Interest income on loan financing”. If the sale of products includes a determinable amount for subsequent services (multiple-component contracts), the related revenues are deferred and recognized as income over the relevant service period. Amounts are normally recognized as income by reference to the pattern of related expenditure.
Profits arising on the sale of vehicles for which a Group company retains a repurchase commitment (buy-back contracts) are not recognized until such profits have been realized. The vehicles are included in inventories and stated at cost.
