| Seasann an ball seo d’idirbhearta nó d’imeachtaí eile ina bhfaigheann faighteoir rialú ar ghnó amháin nó níos mó. Comhcheangail ghnó freisin is ea idirbhearta, dá ngairtear ‘fíorchumaisc’ nó ‘cumaisc ghnóthaí comhionanna’ uaireanta toisc go n‑úsáidtear an téarma sin in IRFS 3. | ga | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
