On infrastructure assets, the municipality ddetermined the cost of each component (BoQs/obtain invoices from suppliers), capitalised all assets at component level, useful lives also changed and the effect of the changes in useful lives was restated retrospectively and all unbundled infrastructure assets were valued at depreciated replacement cost upon initial take-on. On land and buildings and investment properties, the municipality utilised the valuation roll to determine the value of properties to be recognised on 1 July 2007, and no depreciation was calculated on land as these assets were deemed to have an indefinite useful life. Buildings were depreciated over their expected useful life.
