London - British insurer Aviva on Thursday said it had swung back into profit during 2013 as it underwent major restructuring and after it avoided a huge write-down suffered the previous year.
Net profit stood at $3.34bn last year, the company announced in a results statement.
Aviva had tumbled into a huge loss during 2012 owing mainly to a massive write-down following the sale of its US business.
"The turnaround at Aviva is intensifying," chief executive Mark Wilson said in the statement.
"Following our exit from a number of low margin, underperforming or non-strategic businesses, Aviva is simpler, more focused and better managed. We have significantly improved our capital surplus, increased our liquidity and have a stronger leadership team.
"Although we have made progress in 2013, I want to guard against complacency."
Aviva on Thursday added that operating profit - an indicator of its day-to-day business - rose 6.0% in 2013 compared with the previous year thanks to a jump in sales of new insurance policies.
