At present SL. is both a life insurer and a fund manager. Aberdeen is exclusively a fund manager. Consequently after the merger, if it goes ahead, the combined business will be both a life insurer and fund manager. That is the same as SL. is now but with a greatly enlarged fund management arm.
Note that I don’t follow any official sector classifications for HYP selections but make my own decisions on the nature of a business and the degree to which it is diversified from other holdings in a portfolio.
