Chorus has reported an increase in its regulated asset base (RAB) for the 2023 disclosure year, which rose from $5.7 billion to $5.9b.

The telecommunications company said the RAB closing value would serve as the opening RAB for the next regulatory period starting in January 2025.

Additionally, Chorus revealed it had under-earned its total allowable revenue for 2023, resulting in a wash-up balance of $54m.

This balance, combined with the 2022 balance, will be carried forward to 2025, amounting to a total of $105m.

All the calculations are now subject to review by the Commerce Commission.
