| This member stands for hedged items. A hedged item can be a recognised asset or liability, an unrecognised firm commitment, a forecast transaction or a net investment in a foreign operation. The hedged item can be: (a) a single item; or (b) a group of items (subject to paragraphs 6.6.1–6.6.6 and B6.6.1–B6.6.16 of IFRS 9). A hedged item can also be a component of such an item or group of items (see paragraphs 6.3.7 and B6.3.7–B6.3.25 of IFRS 9). This member also represents the standard value for the 'Hedged items' axis if no other member is used. | en | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |

| Seasann an ball seo do mhíreanna fálaithe. Is féidir le mír fhálaithe a bheith ina sócmhainn nó dliteanas aitheanta, ina ceangaltas daingean neamhaitheanta, ina hidirbheart réamhaisnéise nó ina glaninfheistíocht in oibríocht eachtrach. Féadfaidh an mhír fhálaithe a bheith ina: (a) mír aonair; nó (b) grúpa míreanna (faoi réir mhíreanna 6.6.1–6.6.6 agus B6.6.1–B6.6.16 de IFRS 9). Féadfaidh mír fhálaithe a bheith ina comhpháirt de mhír den sórt sin nó de ghrúpa den sórt sin freisin (féach míreanna 6.3.7 agus B6.3.7–B6.3.25 de IFRS 9). Léirítear leis an mball seo freisin an luach caighdeánach le haghaidh na haise ‘Míreanna fálaithe’ mura n‑úsáidtear aon bhall eile. | ga | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
