Water supplier United Utilities says it is on track to deliver results in line with expectations, with the recent regulatory price review for the 2010 to 2015 period now water under the bridge.The company, which operates the water and wastewater network in the Northwest of England, has been selling non-regulated businesses as it concentrates on its core activities, earning about £600m.'We believe that, with the group's consistent focus on its core activities and the low cost of its debt portfolio, we are well positioned to deliver outperformance over the 2010-15 regulatory period,' the company said.UU expects profits to be lower this year due to the impact of the price review, which took effect on April 1 and provides for lower prices and higher capital investment.
