Trade receivables have been aged according to their original due date in the above ageing analysis, including where certain long outstanding trade
receivables have been renegotiated as a result of the extended nature of some of the Group’s service provision. No collateral has been obtained for any
amounts that have been identified as impaired or overdue but not impaired.
The majority of the Group’s receivables are in the form of contracted agreements with customers. Most significant customers are government bodies,
multinational corporations and large domestic businesses who are perceived as low risk. In general, the terms and conditions of these contracts require
settlement of invoices between 14 and 60 days from invoice date. On occasion, the terms and conditions may differ as a result of the varied nature and
timing of some of our operations and maintenance services. Impairment losses are mainly attributed to dispute resolutions as opposed to default of
payments.
(c) L iquidity risk
Liquidity risk is the risk of not being able to meet current or future financial obligations. Prudent liquidity risk management implies maintaining sufficient
cash and marketable securities and the availability of funding through an adequate amount of committed credit facilities. Group Treasury aims at
maintaining flexibility in funding by keeping committed credit lines available for the business. At statement of financial position date the Group had
sufficient headroom from its banking facility to meet its obligations.
