AER - APA VTS - Post tax revenue model - 2021 Return on debt update - October 2020

In line with our final decision on APA VTS's gas transmission network, we have updated APA VTS's return on debt for 2021. As a result of this update, the return on debt for 2021 is 4.31 per cent. This results in an X-factor for 2021 of 1.56 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.
