Note 14: Cash and Cash Equivalents 2021 US$m 2020 US$m Cash at bank and on hand 1,426.0 773.4 Cash deposits 382.8 421.0 Total cash and cash equivalents 1,808.8 1,194.4 Cash and cash equivalents are held for the purpose of meeting short term cash commitments rather than for investment or other purposes. They are made up of: • Cash on hand. • At call deposits with banks or financial institutions. • Investments in money market instruments with original maturities of six months or less, that are readily convertible to known amounts of cash and subject to insignificant risk of changes in value. For the purposes of the cash flow statement, cash at the end of the financial year is net of bank overdraft amounts. Cash flows are presented on a gross basis. The GST component of cash flows arising from investing and financing activities that are recoverable from or payable to a taxation authority are presented as part of operating cash flows. Note 15: Trade Receivables and Payables (a) Trade and other receivables 2021 US$m 2020 US$m Current Trade receivables 997.0 1,121.1 Contract assets 234.5 191.2 Less: Provision for expected credit loss (23.5) (25.3) 1,208.0 1,287.0 Sundry receivables 355.7 271.2 Prepayments 147.5 145.7 Carrying amount of current receivables and contract assets 15 1,711.2 1,703.9 Non Current Long term deposits/other receivables 6.6 14.3 Carrying amount of non-current trade and other receivables 15 6.6 14.3 Trade, other receivables, and contract assets are initially recorded at fair value and are generally due for settlement within 30 to 60 days from date of invoice. Collectability is regularly reviewed at an operating unit level. A provision for expected credit loss (ECL) is recognised based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Group expects to receive, discounted at an approximation of the original effective interest rate. Cash flows relating to short-term receivables are not discounted if the effect of discounting is immaterial. When a trade receivable for which a provision for expected credit loss has been recognised becomes uncollectible in a subsequent period, it is written off against the provision. ECLs are recognised in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL). For trade receivables and contract assets, the Group applies a simplified approach in calculating ECLs. Therefore, the Group does not track changes in credit risk, but instead recognises a loss allowance based on lifetime ECLs at each reporting date. CSL Limited Annual Report 2020/21 135
