| Seasann an ball seo do gach toimhde achtúireach. Is éard is toimhdí achtúireacha ann na meastacháin neamhchlaonta is fearr, atá comhoiriúnach go frithpháirteach, ón eintiteas faoi na hathróga déimeagrafacha agus airgeadais lena gcinnfear an costas a bheidh i gceist le sochair iarfhostaíochta a sholáthar ar deireadh.
