13. 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 2 and 15 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 2069. 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 of Rp5,294 billion and low-value assets lease expense of Rp65 billion were incurred for the year ended December 31, 2019.
