NOTES TO THE FINANCIAL STATEMENTS FOR THE FINANCIAL YEAR ENDED 31 DECEMBER 2017 FINANCIAL STATEMENTS WAH SEONG CORPORATION BERHAD ANNUAL REPORT 2017 93 2 SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 2.7 Property, plant and equipment (continued) (a) Measurement basis (continued) Subsequent costs are included in the asset’s carrying amount when it is probable that future economic benefits associated with the asset will flow to the Group and the Company and the cost of the asset can be measured reliably. The carrying amount of the replaced part is derecognised. All other repair and maintenance costs are charged to the profit or loss during the financial year in which they are incurred. At each reporting date, the Group and the Company assess whether there is any indication of impairment. Where an indication of impairment exists, the carrying value of the asset is assessed and written down immediately to its recoverable amount. See accounting policy 2.14 on impairment of non-financial assets. Property, plant and equipment are derecognised upon disposal or when no future economic benefits are expected from their use. Gains and losses on disposals are determined by comparing proceeds with carrying amounts and are included in the profit or loss in the financial year the asset is derecognised. (b) Depreciation Freehold land is not depreciated as it has an indefinite life. Depreciation on capital work-in-progress commences when the assets are ready for their intended use. Depreciation is calculated to write off the depreciable amount of other property, plant and equipment on a straight line basis over their estimated useful lives. The depreciable amount is determined after deducting residual value from cost. The estimated useful lives of the property, plant and equipment are as follows: Buildings 10 – 50 years Plant, machinery, tools and equipment 2 – 25 years Electrical installations, office equipment and furniture and fittings 4 – 10 years Computer equipment 3 – 10 years Motor vehicles 3 – 5 years Renovation, yard development and store extension 2 – 50 years Assets under construction included in plant and equipment are not depreciated as these assets are yet to be available for use. The residual values, useful lives and depreciation methods are reviewed, and adjusted if appropriate, at the end of each financial year.
