14. RIGHT OF USE ASSETS

The Group leases several assets including building, transmission installation and equipments, power supply, vehicles, and other equipments used in its operations, which generally have lease term between 1 and 33 years.

The Group leases several pieces of land located throughout Indonesia with Building Use Rights ("Hak Guna Bangunan" or "HGB") for a period of 10-50 years which will expire between 2020 and 2070. Management believes that there will be no issue in obtaining the extension of the land rights when they expire.

The Group also has certain leases with lease terms of twelve months or less and low-value leases. The Group applies the ‘short-term lease’ and ‘lease of low-value assets’ recognition exemptions for these leases. There are no lease contracts with variable lease payments. Short-term lease expense as of 2019 and 2020 amounted to Rp5,294 billion and Rp3,612 billion, respectively. Low-value assets lease expense as of 2019 and 2020 amounted to Rp65 billion and Rp119 billion, respectively.
