PPE may have parts with different useful lives. Depreciation is calculated based on each individual part’s
life. When one part is replaced, the new part is capitalised to the extent that it meets the recognition criteria
of an asset, and the carrying amount of the parts replaced is derecognised.
The cost of a major inspection or overhaul of an item, occurring at regular intervals over the useful life of
the item, is capitalised to the extent that it meets the recognition criteria of an asset. The carrying amount
of the parts replaced is derecognised.
