✨ Electricity Performance Measures

NEW ZEALAND GAZETTE

No. 149

Counties Power Limited – Line Business

1 April 1998 to 31 March 1999

1. Financial Performance Measures

	1999	1998	1997	1996
(a) Return on funds, being earnings before interest and tax (as adjusted), divided by average total funds employed (as adjusted).	7.3%	4.1%	2.2%	3.1%
(b) Return on equity, being net profit after tax (as adjusted), divided by average total equity (as adjusted).	6.1%	3.0%	1.8%	2.1%
(c) Return on investment	5.9%	18.5%	1.2%	2.3%

2. Efficiency Performance Measures

	1999	1998	1997	1996
(a) Direct line costs per kilometre	$934	$1,218	$1,176	$1,091
(b) Indirect line cost per consumer	$83	$84	$79	$96

Indirect line cost per consumer has been calculated using estimated average consumer numbers. The methodology used to calculate this estimate is publicly available.

Note: 31 March 1999 financial and efficiency performance measures have been prepared in accordance with the requirements of the Electricity (Information Disclosure) Regulations 1999. Figures for previous years were prepared in accordance with the requirements of the Electricity (Information Disclosure) Regulations 1994. The method of calculation specified in the two sets of regulations is not identical, and consequently figures for 31 March 1999 are not directly comparable to the previous years.

As the Gazette has been published for more than 185 years, copyright status depends on the publication date of each issue:

1840–1925 (Public Domain): Issues of the New Zealand Gazette and Provincial Gazettes from this period are in the public domain, as the term of Crown copyright (100 years) has expired. Mechanical reproductions (e.g., scanned PDFs) of these public domain documents do not attract new copyright.
1926–1999 (Crown Copyright): Issues from this period remain subject to Crown copyright. Usage of these issues in this project is "Fair Dealing" for research purposes and consistent with the spirit of the open-access principles championed by NZGOAL, ie, "The default licensing position under ...
