Note 9 on page 45 also has this description:
The accrued revenue balance of $71.6 million (2013: $88.3 million) represents revenue which has yet to be invoiced to customers at year-end, due to either the invoicing process not being finalised or work not yet reaching a stage where it can be invoiced. Many of the Group’s customers require payment claims to be submitted and approved prior to invoices being issued. Although this extends the time revenue is held as accrued, historically it does result in high level of recoverability of trade debtors. Where work has not yet reached a stage where it can be invoiced, revenue is accrued in line with the Group’s accounting policies as outlined at notes 33.7 revenue recognition and 33.8 construction contracts.
