TSO Update: Net cost calculation & TSO instrument
The annual process of determining the net cost to Telecom New Zealand Limited of providing local residential telephone
services under the telecommunications service obligations (TSO) deed has commenced, with Telecom providing its own net
cost calculation for the 2002/2003 financial year.
Telecom is required to provide the Commission with its own net cost calculation not later than 60 working days after the
end of its financial year. Telecom's calculation for the period from 1 July 2002 to 30 June 2003 is $215.5 million.
Telecom's calculation is based on the methodology used by the Commission in its 2001/2002 draft determination, with the
exception of the weighted average cost of capital (WACC). Telecom used a WACC of 13.1 percent, in contrast to the 6
percent WACC used by the Commission in that determination. The Commission will consider Telecom's calculation in its
determination of the 2002/2003 TSO costs.
The Telecommunications Act requires the Commission to determine the net cost of TSO to Telecom, and to apportion that
cost across both Telecom and other network operators providing retail services.
The Commission is currently finalising its cost calculation for the 2001/2002 financial year, and expects to complete
its final determination in October 2003.
In addition to the net cost of TSO, Telecom is required to provide an annual assessment of compliance with the service
quality measures defined in the TSO instrument. The Commission in turn is required to review Telecom's compliance with
the TSO instrument, and notify Telecom and the Minister of Communications in writing of any non-compliance by Telecom
with the TSO instrument.
Manager of the Commission's Network Access Group, Osmond Borthwick, said the Commission has received Telecom's
assessment for 2002/2003 and has concluded that the TSO service quality measures have been met for the period.
"The basic measurement methodology is the same as that for the previous period, involving a number of complex sampling
processes and approximations. Accuracy has been enhanced through increasing the number of network devices sampled," said
He added that the Commission reserves its position on appropriate measurement methodology for future periods and will
require progressive expansion of sampling to improve robustness and adequate levels of reporting on internet "line
