The decrease in 'Trade debtors' of US$47 million is mainly thanks to improved cash collection and an offsetting agreement between the Company and some of the joint ventures signed in 2019.

The increase in 'Prepayments' of US$28 million is a result of advance payments in relation to the construction of a new multi-purpose floater hull which has been allocated to the FPSO Sepetiba.

The increase in accrued income in respect of delivered orders of US$38 million is a result of the completion of the FPSO Liza Destiny project during the current year.

The carrying amounts of the Company’s trade debtors are distributed in the following countries:

The allowance for impairment represents the Company’s estimate of losses in respect of trade debtors. The allowance related to credit risk for significant trade debtors is built on specific expected loss components that relate to individual exposures. Furthermore, the Company uses historical credit loss experience as well as forward-looking information to determine a 1% expected credit loss rate on individually insignificant trade receivable balances. The creation and release for impaired trade debtors due to credit risk are reported in the line item ’Net impairment losses on financial and contract assets’ of the consolidated income statement. Amounts charged to the allowance account are generally written off when there is no expectation of recovery.

The ageing of the nominal amounts of the trade debtors are:

Not past due are those receivables for which either the contractual or ’normal’ payment date has not yet elapsed. Past due are those amounts for which either the contractual or the ’normal’ payment date has passed. Amounts that are past due but not impaired relate to a number of Company joint ventures and independent customers for whom there is no recent history of default, or the receivable amount can be offset by amounts included in current liabilities.

For the closing balance and movements during the year of allowances on trade receivables, please refer to note 4.3.29 Financial Instruments − Fair Values and Risk Management.
