South African shipowner Grindrod has braced investors for a loss of up to $30m in the first half.

In a profit warning issued today Grindrod said it would carry a ZAR 675m ($50m) impairment on its rail activity.

It comes following a strategic decision to sell the locomotive assembly business, investors were told in a trading update.

Grindrod said its first half headline loss would ring in at between ZAR 340m and ZAR 400m, which will reverse a headline profit of ZAR 303m in the same period of 2015.
