| Note: | The Company shall apply these amendments to plan amendments, curtailments or settlements occurring on or after January 1, 2019.
Except for the following, the Company believes that the adoption of aforementioned standards or interpretations did not have a significant effect on the Company’s accounting policies:
| 1) | IFRS 16 “Leases”
IFRS 16 sets out the accounting standards for leases that supersedes IAS 17 “Leases”, IFRIC 4 “Determining whether an Arrangement contains a Lease”, and a number of related interpretations. Refer to Note 5 for information relating to the relevant accounting policies. Definition of a lease The Company applies the guidance of IFRS 16 in determining whether contracts are, or contain, a lease only to contracts entered into (or changed) on or after January 1, 2019. Contracts identified as containing a lease under IAS 17 and IFRIC 4 are not reassessed and are accounted for in accordance with the transitional provisions under IFRS 16. The Company as lessee Except for payments for short-term leases which are recognized as expenses on a straight-line basis, the Company recognizes right-of-use assets and lease liabilities for all leases on the consolidated statements of financial position. On the consolidated statements of profit or loss and other comprehensive income, the Company presents the depreciation expense charged on right-of-use assets separately from the interest expense accrued on lease liabilities, which is computed using the effective interest method. On the consolidated statements of cash flows, cash payments for both the principal portion and the interest portion of lease liabilities are classified within financing activities. The Company applies IFRS 16 retrospectively with the cumulative effect of the initial application recognized at the date of initial application but does not restate comparative information. Leases agreements classified as operating leases under IAS 17, except for short-term leases, are measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate on January 1, 2019. Right-of-use assets are measured at an amount equal to the lease liabilities, adjusted by the amount of any prepaid or accrued lease payments. Right-of-use assets are subject to impairment testing under IAS 36. The Company applied the following practical expedients to measure right-of-use assets and lease liabilities on January 1, 2019 :
| a) | The Company applied a single discount rate to a portfolio of leases with reasonably similar characteristics to measure lease liabilities.
| b) | The Company accounted for those leases for which the lease term ends on or before December 31, 2019 as short-term leases.
| c) | Except for lease payments, the Company excluded incremental costs of obtaining the lease from right-of-use assets on January 1, 2019.
| d) | The Company determined lease terms (e.g. lease periods) based on the projected status on January 1, 2019, to measure lease liabilities.
The weighted average lessee’s incremental borrowing rate used by the Company to calculate lease liabilities recognized on January 1, 2019 is 1.46%. The reconciliation between the lease liabilities recognized and the future minimum lease payments of non-cancellable operating lease on December 31, 2018 is presented as follows:
|  | NT$ |
|  | (In Millions) |
The future minimum lease payments of non-cancellable operating lease on December 31, 201 8 |  | $ | 20,849.6 |
Less: Recognition exemption for short-term leases |  |  | (3,189.8 | )
Undiscounted gross amounts on January 1, 2019 |  | $ | 17,659.8 |
Discounted using the incremental borrowing rate on January 1, 2019 |  | $ | 16,465.6 |
Add: Adjustments as a result of a different treatment of extension and purchase options |  |  | 3,438.0 |
Lease liabilities recognized on January 1, 2019 |  | $ | 19,903.6 |
The Company as lessor Except for sublease transactions, the Company does not make any adjustments for leases in which it is a lessor, and accounts for those leases under IFRS 16 starting from January 1, 2019. On the basis of the remaining contractual terms and conditions on January 1, 2019, all of the Company’s subleases are classified as operating leases.
