Prudential's new chief executive, Mark Tucker, is reviewing the future of both Egg, the on-line bank, and Jackson National Life.
Both, he said yesterday are "clearly under review", while giving no hint of what his conclusions are likely to be.
These will be revealed along with Prudential's thirdquarter sales numbers in October.
"I am not charging in and making dramatic changes," Mr Tucker said. "That is neither my style or my intention.
"I am not going to rush into any quick decisions or make any immediate major announcements."
Mr Tucker's predecessor, Jonathan Bloomer, put Egg publicly on the market 18 months ago, only to withdraw it when no bidder emerged offering an acceptable price. This failure was said to be one of the factors leading to Mr Bloomer's departure under pressure from City investors.
Yesterday Mr Tucker presented results showing Prudential made a brisk start to 2005, with achieved half-time profits from continuing operations up 31 per cent at £834 million.
Insurance sale in the UK and Europe were 50 per cent up to the equivalent of annual premiums of £541 million, boosted by the acquisition of Phoenix Life & Pensions.
Without Phoenix, sales rose by ten per cent in a market rising by an estimated two to three per cent.
"We have delivered doubledigit sales growth in all our markets while maintaining margins at a group level," Mr Tucker said.
"We are taking advantage of our strong presence across the diverse markets in which we operate.
"As you would expect, I am actively reviewing long-term trends and opportunities in order to anticipate the changing needs of our customers."
The interim dividend is raised by a cautious 2.1 per cent to 5.3p. The shares closed 12p higher at 536.5p, a new 12-month high.
Prudential reported a profit margin of 37 per cent on its sales, up from 36 per cent despite a fall in Asian margins.
UK profits, though, were down 24 per cent at £ 182 million, hit by a £132 million charge for individuals surrendering some policies earlier than expected.
Mr Tucker said Prudential was on target to achieve a ten per cent sales growth in the UK this year, despite tough competition.
In the job for less than three months, he said he saw room for further profitable growth across all three of the group's geographic regions: Asia, the UK and the United States.
Dave Bradbury, a fund manager with Canada Life, said, "He is still evolving his thinking about the businesses and it looks like we will know more in October. I think that is a sensible strategy. These are complex businesses."
