Sir Adrian Montague, Friends Provident chairman, said the group was on track with its new strategy but there was "still a lot to do".
"The strong headway made in implementing our new strategy, coupled with other timely initiatives taken to reduce our exposure to financial markets, has enabled the company to weather the subsequent sharp economic downturn more favourably than otherwise would have been the case," he said.
"Our business has no need to raise capital to fund growth, and our revised dividend policy remains sustainable."
The firm also warned there was a risk a prolonged economic downturn will cut the insurer's income.
