It was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index but was acquired by the Pearl Group in May 2008.

In September 2005, Resolution Life merged with the FTSE company Britannic Group, who had closed to new business in 2003.

[citation needed] In 2006, the merged group bought the life business of Abbey National, a transaction of £3.6 billion that brought entry into the FTSE 100.

On 10 October 2007, Pearl made a formal offer of 660 pence per share, worth approximately £4.5 billion, in conjunction with the Royal London Mutual Insurance Society.

In addition, Hugh Osmond, chief executive of Pearl, now controlled a stake of 24.1% of Resolution's ordinary shares, which would have effectively blocked any planned merger from Standard Life as it would have required 75% approval from shareholders.
