    End of attention

    The sort of information which you could use to make an estimate of effective life of an asset includes:

    • the physical life of the asset
    • engineering information
    • the manufacturer's specifications
    • your own past experience with similar assets
    • the past experience of other users of similar assets
    • the level of repairs and maintenance commonly adopted by users of the asset
    • retention periods, and
    • scrapping or abandonment practices.

    You work out the effective life of a depreciating asset from the asset's start time.
