Royal & Sun Alliance Insurance Group (R&SA) is set to regain blue-chip status after a brief three-month absence from the FTSE 100 index.
R&SA was ejected from the index of leading shares in the last quarterly review in March, but based on Tuesday's closing share prices, the insurer ought to qualify for the index.
A FTSE International source told AFX News that insurance outsourcing specialist Capita was among several firms likely to lose its blue chip status.
FTSE will confirm the changes later today and changes to the actual indices will take effect after the close of the UK market on June 20.
Under FTSE rules, companies outside the FTSE 100 will gain automatic promotion to the blue-chip index if their share prices have risen enough to place them among the 90 biggest listed companies.
Similarly, any FTSE 100 member, which falls to 111th spot or below, will be automatically demoted to the FTSE 250.
The rejig happens four times a year to ensure the FTSE 100 represents Britain's biggest publicly listed companies.
