9. OPERATING COSTS & TAX Operating costs: CPS forecasts increases in expenditure of 8% Pension costs account for about a third of this Other concerns include bad debt Inland Revenue changing the way it treats certain types of expenditure

10. FUTURE EFFICIENCY Scope for future efficiency is less than at previous reviews Companies’ estimates deliver a reduction of £10 (4% over 5 years) on the average bill We continue to refine our view on efficiency. Latest analysis suggests the efficiency savings will be less than the 3% pa assumed for draft business plans

11. ECONOMIES OF SCALE Perennial issue - Water Act completes new merger provisions Commissioned consultants to look at evidence for scale economies Technical report - not about Ofwat merger policy Any change would require new legislation

12. FINANCEABILITY A company’s cash flow, revenues and profits must allow it to raise finance on reasonable terms For some companies a significant element of price limits is to achieve their view of an acceptable financial profile Large capital programmes mean companies will not generate positive cash flows

13. COST OF CAPITAL WaSCs draft business plan estimates for WACC ranged from 5.2% to 5.8% All argued that the WACC used at PR99 was too low - too early to draw firm conclusions but no good case for setting below PR99 level To clarify - by this we mean 5.0%

14. NEXT STEPS Ofwat:company meetings to discuss draft plans Secretary of State principal guidance (roughly end January) Final business plans (7 April ’04 submission to Ofwat) Draft determinations (28 July ’04) (for consultation with WaterVoice and others) Final determinations (25 November ’04)

18. A SUSTAINABLE FUTURE? Continuing essential improvements to environment and drinking water. Infrastructure that continues to support high quality water and sewerage services. Stable companies which have the confidence of investors and the incentive to generate further efficiency. Customers who can see that increases in bills are justified by value.
