5 SEPTEMBER NEW ZEALAND GAZETTE 3083

K. PERFORMANCE MEASURES

	Dunedin Area Only
	2000	1999	1998	1997
Disclosures of financial performance measures and efficiency performance measures under Regulation 15 of the Electricity (Information Disclosure) Regulations 1999
1. Financial performance measures
(a) Return on funds	13.2%	15.2%	13.1%	14.0%
(b) Return on equity	29.9%	9.1%	7.7%	8.2%
(c) Return on investment	10.7%	9.1%	8.9%	14.1%
Return on investment as restated – see below	8.6%	9.1%	8.9%	8.6%
Notes
(i) The ODV increased in the 1997 year due to the lives of certain assets being extended. This movement in reported ODV does not reflect an increase in economic value, rather than a change in the basis of calculation. If the ARP had been restated to exclude this portion of the revaluation, it would have been 8.6%.
(ii) The ODV increased in the 2000 year due to the December 1999 revaluation. The ROI has been restated to exclude the effect of the revaluation.
2. Efficiency performance measures
(a) Direct line costs per kilometre	$2,325	$3,314	$3,083	$2,996
(b) Indirect line costs per electricity consumer	$15.66	$21.08	$23.76	$19.31

Disclosures of delivery efficiency performance measures and statistics under Regulation 21 of the Electricity (Information Disclosure) Regulations 1999

Energy Delivery efficiency performance measures

	2000	1999	1998	1997
(a) Load factor	56%	56%	57%	53%
(b) Loss ratio	6.0%	5.8%	5.9%	5.6%
Note – the loss ratio is deduced from reports of energy injected by others and reports of retail sales by others. Dunedin Electricity is unable to audit these reports and has little confidence in their accuracy. Accordingly the ratio should be treated with great caution.
(c) Capacity utilisation	35.0%	36.5%	36.6%	40.0%
