Remaining asset lives at 1 July 2013 For this final decision, we have updated the revised remaining asset lives to reflect our adjustments to Murraylink's actual capex inputs for the RFM, as discussed in section 6. This is because the actual capex values are inputs for calculating the weighted average remaining asset lives in the RFM. In the draft decision, we adjusted Murraylink's proposed inputs to the RFM and accordingly, updated the remaining asset lives at 1 July 2013. Murraylink's revised proposal continued to apply the weighted average method to calculate the remaining economic lives as accepted by us in the draft decision. Table 7.3 sets out our final decision on Murraylink's remaining asset lives at 1 July 2013 for the 2013–18 regulatory control period.
