| Report the value, for the reporting period, of the retirement benefits paid during the reporting period as part of directors remuneration in relation to defined contribution plans. Defined contribution plans are post-employment benefit plans under which an entity pays fixed contributions into a separate entity (a fund) and will have no legal or constructive obligation to pay further contributions if the fund does not hold sufficient assets to pay all employee benefits relating to employee service in the current and prior periods. | en | http://xbrl.ssm.com.my/role/ssm/fs/clbg/lab_rol_ssmt-fs-clbg_2017-12-31/ReportingDocumentation | http://www.xbrl.org/2003/role/link |
