Paragraphs:
15 Financial risk management (continued)
(b) Credit risk
Credit risk arises from cash and cash equivalents, and trade and other receivables.
(ii) Trade and other receivables
Customer credit risk is managed subject to the Group’s established policy, procedures and control relating to customer credit risk management. Credit evaluations are performed on all customers. Outstanding customer receivables are monitored regularly.
The Group aims to minimise concentration of credit risk by undertaking transactions with a large number of customers. In addition, receivable balances are monitored on an ongoing basis with the intention that the Group’s exposure to bad debts is minimised.
Revenues from data centre services of $61.2 million were derived from two customers (2018: $44.4 million from one customer) whose revenue comprised more than 37% (2018: 29%) of total data centre services revenue.
The maximum exposure to credit risk at the end of the reporting period is the carrying value of each class of the financial assets mentioned above and each class of receivable disclosed in Note 5. The Group does not require collateral in respect of financial assets.
The Group applies the simplified approach to providing for expected credit losses prescribed by AASB 9, which permits the use of the lifetime expected loss provision for all trade receivables. The loss allowance provision as at 30 June 2019 is determined as follows; the expected credit losses below also incorporate forward looking information.
