One option involves hiving off Old Mutual Wealth and either listing it in London or selling it.
Private equity firms are reportedly interested in buying the division, which is valued at about £4 billion by analysts and has prospered in the wake of UK pension reforms.
Old Mutual, which was founded in 1845, would subsequently de-list from the FTSE 100 but keep a Johannesburg listing for the remaining bits of the firm. Sources said keeping with the status quo is still an option.
