Consumption of some base metals and their dlr prices are showing signs of improvement, although iron ore markets have weakened. The oil price in U.S. Dlrs is above the 1986 average, and if sustained, should improve energy earnings.

Pretax profits also dipped to 601.7 mln stg after 614.4 mln. RTZ said the excellent performance of its expanding range of industrial businesses in 1986 was offset by the collapse in oil prices.

Trading performance improved at wholly-owned subsidiaries RTZ Borax Ltd, RTZ Cement Ltd, RTZ Chemicals Ltd and RTZ Pillar Ltd.
