pre_text: 9.2. Trade and other receivables Classification as trade and other receivables Trade receivables are amounts due from customers for rental income, goods sold or services performed in the ordinary course of business. Loans and other receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. If collection is expected in one year or less, they are classified as current assets. If not, they are presented as non-current assets. The allowance for expected credit losses represents an estimate of receivables that are not considered to be recoverable. For the year ended 30 June 2019 the Group has recognised an expected loss provision following the adoption of AASB 9 Financial Instruments. The Group recognises a loss allowance based on lifetime expected credit losses at each reporting date. The Group assesses this allowance based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors. At 30 June 2018, the Group recognised a provision for trade receivables relating to receivables acquired on the purchase of investment properties where there are specific risks around recoverability.
