Insurance group FBD has reported pre-tax profits of €185m for 2005.
The previous year's figure stood at €115m.
Strong new business volumes boosted the figures despite reductions in premiums during the year, according to the firm.
The group's total income climbed to €404.5m last year, up from €355m in 2004.
FBD's total written premiums rose to €389.5m last year, up from €351.5m.
The company's Chief Executive Philip Fitzsimons said he anticipates further premium reductions in certain areas if claims and pricing trends continue.
