Trade receivables
Trade receivables are amounts due from customers for the sale of services in the normal course of business. Receivables slated for collection in twelve months or less are classified as current assets; otherwise, the balances are considered noncurrent assets.
Trade receivables are recognized at the original invoice amount. An impairment provision is recorded when there is objective evidence of collection risk. The amount of the impairment provision is calculated as the difference between the carrying amount of the doubtful trade receivables and their recoverable amount. In general, cash flow relating to short-term receivables is not discounted.
