The Group’s lease liabilities were mainly from land and buildings and improvements. The range of discount rates for lease liabilities was as follows:
|  | December 31 |

Land (%) |  |  | 0.54-8.00 |  |  |  | 0.54-8.00 |

| c. | Material lease-in activities and terms
The Group leases land and buildings for the use of plants and offices with remaining lease terms of 1-52 years and 1-28 years, respectively. For the leasehold land located in the R.O.C., the Group has extension options at the expiry of the lease periods. However, the government has the right to adjust the lease payments on the basis of changes in announced land value prices and also has the right to terminate the lease contract under certain circumstances. The Group does not have bargain purchase options to acquire the leasehold land and buildings at the expiry of the lease periods. In addition, the Group is prohibited from subleasing or transferring all or any portion of the underlying assets without the lessor’s consent.
| d. | Subleases
In addition to the sublease transactions described in Note 17, the Group did not have other sublease transactions.
