In line with our final decision on Australian Gas Networks' gas distribution network, we have updated Australian Gas Networks' return on debt for 2017–18 under NGR r. 87(12).

As a result of this update, the return on debt for 2017–18 is 5.47 per cent. This results in an X-factor for 2017–18 of –3.59 per cent. Holding other things constant, a positive X-factor implies a real revenue decrease and a negative X-factor implies a real revenue increase.

The revised PTRM shows the updated X-factor.

On 15 December 2017 the AER wrote to AGN South Australia setting out how it proposed to correct a mathematical error in the inflation calculation in its 26 May 2016 decision.
