Hanson is expecting trading profit to increase by around 12 per cent in 2005 in spite of higher energy costs, with the main improvements coming from the United States and Australia.  In North America, aggregates prices were raised by an average eight and 10 per cent increase was achieved in ready-mixed concrete, asphalt and cement. Cement shortages in Arizona have restricted ready-mixed concrete deliveries there.  In California, where the group has its own cement plant, one price increase has been announced for 2006, but a second price increase later in the year remains a possibility.  Australia has performed well, in particular the associate Cement Australia, which is a significant contributor there.
