27 Financial risk management (continued)
Credit risk
Credit risk is the risk of financial loss if a tenant or counterparty fails to meet an obligation under a contract. Credit risk arises primarily from trade receivables but also from other financial assets with counterparties including loans to joint ventures, cash deposits and derivative financial instruments.
– trade receivables
Credit risk associated with trade receivables is actively managed; tenants are typically invoiced quarterly in advance and are managed individually by asset managers, who continuously monitor and work with tenants, aiming wherever possible to identify and address risks prior to default.
Prospective tenants are assessed via a review process, including obtaining credit ratings and reviewing financial information, which is conducted internally. As a result deposits or guarantees may be obtained. The amount of deposits held as collateral at 31 December 2019 is £3.5 million (2018: £3.5 million).
When applying a loss allowance for expected credit losses, judgement is exercised as to the collectability of trade receivables and to determine if it is appropriate to impair these assets. When considering expected credit losses, management has taken into account days past due, credit status of the counterparty and historical evidence of collection.
The ageing analysis of trade receivables is as follows:
