| Report the value, for the reporting period, of adjustments for the changes in fair value of investment properties to reconcile profit (loss) to net cash flow from (used in) operating activities. Fair value of the investment properties is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Investment properties are property (land or a building—or part of a building—or both) held (by the owner or by the lessee under a finance lease) to earn rentals or for capital appreciation or both, rather than for: (a) use in the production or supply of goods or services or for administrative purposes; or (b) sale in the ordinary course of business. | en | http://xbrl.ssm.com.my/role/ssm/fs/mfrs/lab_rol_ssmt-fs-mfrs_2017-12-31/ReportingDocumentation | http://www.xbrl.org/2003/role/link |
