In line with our final decision on APTPPL's gas transmission network, we have updated RBP's return on debt for 2023–24. As a result of this update, the return on debt for 2023–24 is 4.34 per cent. This results in an X-factor for 2023–24 of -0.41 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.
