| This member stands for the estimates of the present value of the insurance acquisition cash flows. Insurance acquisition cash flows are cash flows arising from the costs of selling, underwriting and starting a group of insurance contracts (issued or expected to be issued) that are directly attributable to the portfolio of insurance contracts to which the group belongs. Such cash flows include cash flows that are not directly attributable to individual contracts or groups of insurance contracts within the portfolio. | en | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |

| Seasann an ball seo do na meastacháin ar luach reatha na sreafaí airgid éadála árachais. Is éard is sreafaí airgid éadála árachais ann sreafaí airgid a eascraíonn as na costais a bhaineann le grúpa conarthaí árachais (a eisíodh nó a bhfuil coinne ann go n‑eiseofar iad) a dhíol, a fhrithghealladh agus a thosú, costais atá inchurtha go díreach i leith na punainne conarthaí árachais lena mbaineann an grúpa. Áirítear le sreafaí airgid den sórt sin sreafaí airgid nach bhfuil inchurtha go díreach i leith conarthaí aonair nó grúpaí conarthaí árachais laistigh den phunann. | ga | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
