Grindrod Limited – Annual report – 31 December 2017
Accounting policies (extract)
Ships, property, terminals, vehicles and equipment (extract)
Ships are measured at cost less accumulated depreciation and any impairment losses. Cost comprising acquisition costs and costs directly related to the acquisition up until the time when the asset is ready for use, include interest expense incurred during the period. The market average useful life of a ship is estimated to range from 25 to 30 years at which point it would usually be scrapped. The group maintains a young fleet compared to the market average and estimates useful life as 15 years from date of delivery for new ships. Ships are depreciated on the straight line basis to an estimated residual value over their useful lives to the group. Borrowing costs incurred in the financing of the acquisition of ships prior to their delivery are capitalised to the cost of the ships.
From time to time the group’s vessels are required to be dry-docked for inspection and re-licensing at which time major repairs and maintenance that cannot be performed while the vessels are in operation are generally performed. The group capitalises the costs associated with dry-docking as they occur by adding them to the cost of the vessel and amortises these costs on the straight-line basis over 3-5 years, which is generally the period until the next scheduled dry-docking.
In cases where dry-docking takes place earlier than 5 years since the previous one, the carrying amount of the previous dry-docking is derecognised. In the event of a vessel sale, the respective carrying values of dry-docking costs are derecognised together with the vessel’s carrying amount at the time of sale. At the date of acquisition of a vessel, management estimates the component of the cost that corresponds to the economic benefit to be derived until the next scheduled dry-docking of the vessel under the ownership of the group, and this component is depreciated on the straight-line basis over the remaining period to the estimated dry-docking date.
