Own the structure, not the trade
Sanam Holding was set up in 1986 as a holding company and has operated as one ever since. That is a deliberate architectural choice. A fund raises capital against an exit; a holding company owns operating businesses without a clock running on them.
The consequence shows across the portfolio. The Unimer position dates from 1993. The insurance position, taken through the Saham transaction, was retained rather than sold when Sanlam acquired the wider business. Positions are added to the structure; they are rarely removed from it.
