They need to form a Holding Company then put Equity Bank, Britam and HFCK under it. Give shareholders of each entity shares in the 'parent' [Holding Company] so the 3 firms are 100% subsidiaries.
Britam/Equity Holdings will now be a Financial Supermarket but its subsidiaries operate independently [though each will cross-sell products].
HFCK concentrates on mortgages & property development.
Britam provides long-term funds to HFCK and its core insurance business.
Equity does what it does best. Banking.
Equitel can be a subsidiary of Britam/Equity Holdings with very close links to all 3 finance entities.
