Basis of Presentation and Accounting Policies [Abstract]
Basis Of Presentation And Accounting Policies	2 . BASIS OF PRESENTATION AND ACCOUNTING POLICIES Statement of compliance These condensed interim consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) and in compliance with International Accounting Standard (“IAS”) 34 Interim Financial Report ing as issued by the International Accounting Standards Board (“IASB”). The condensed interim consolidated financial statements of the Company for the three and six months ended February 29 , 20 20 were authorized for issue by the Board of Di rectors on April 9 , 20 20 . a) Basis of presentation These condensed interim consolidated financial statements have been prepared primarily under the historical cost convention except as detailed in the significant accounting policies disclosed in the Compa ny’s consolidated financial statements for the year ended August 31, 201 9 and are expressed in millions of Canadian dollars unless otherwise indicated. The condensed interim consolidated statements of income are presented using the nature classification fo r expenses. Certain comparative figures have been reclassified to conform to the current period’s presentation. The notes presented in these condensed interim consolidated financial statements include only significant events and transactions occurring s ince the Company’s last fiscal year end and are not fully inclusive of all matters required to be disclosed by IFRS in the Company’s annual consolidated financial statements. As a result, these condensed interim consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended August 31, 201 9 . The condensed interim consolidated financial statements follow the same accounting policies and methods of application as the most recent annual c onsolidated financial statements except as noted below. b) New accounting standards We adopted the following new accounting standards effective September 1, 2019.  IFRS 16 Leases was issued on January 2016 and replaces IAS 17 Leases . The new standard requires entities to recognize lease assets and lease obligations on the balance sheet. For lessees, IFRS 16 removes the classification of leases as either operating leases or finance leases, instead requiring that leases be capitalized by recognizing the present value of the lease payments and showing them as lease assets (right-of-use assets) and representing the right to use the underlying leased asset. If lease payments are made over time, the Company recognize s a lease liability repr esenting its obligation to make future lease payments. Certain short-term leases (less than 12 months) and leases of low value may be exempted from the requirements and may continue to be treated as operating leases if certain elections are made. Lessors w ill continue with a dual lease classification model. Classification will determine how and when a lessor will recognize lease revenue, and what assets would be recorded. As a result of adopting IFRS 16, the Company recognized a significant increase to bo th assets and liabilities on our Consolidated Statements of Financial Position as well as a decrease to operating costs, as a result of removing the lease expense, an increase to depreciation and amortization, due to the depreciation of the right-of-use as set, and an increase to finance costs, due to the accretion of the lease liability. Relative to the results of applying the previous standard, although actual cash flows are unaffected, the Company’s statement of cash flows will reflect increases in cash f lows from operating activities offset equally by decreases in cash flows from financing activities. Implementation We adopted IFRS 16 using a modified retrospective approach whereby the financial statements of prior periods presented are not restated. We recognized lease liabilities at September 1, 2019 for leases previously classified as operating leases, measured at the present-value of the lease payments using our incremental borrowing rate at that date, with the corresponding right-of-use asset generally measured at an equal amount, adjusted for any prepaid or accrued rent outstanding as at August 31, 2019. As perm itted by IFRS 16, we applied certain practical expedients to facilitate the initial adoption and ongoing application of IFRS 16 including the following:  not separate fixed non-lease components from lease components for certain classes of underlying assets. Each lease component and any associated non-lease components will be accounted for as a single lease component;  apply a single discount rate to a portfolio of leases with similar characteristics;  exclude initial direct costs from measuring the right-of-us e asset as at September 1, 2019; and  use hindsight in determining the lease term where the contract contains purchase, extension, or termination options. On transition, we have not elected the recognition exemptions on short-term leases or low-value leases; however, we may choose to elect these recognition exemptions on a class-by-class basis for new classes and on a lease-by-lease basis, respectively, in the future. In December 2019 , the IFRS Interpretations Committee issued a final agenda decision in regards to the determination of the lease term for cancellable or renewable leases under IFRS 16. The Company is currently assessing the im pact of this interpretation on its financial . There was no significant impact for contracts in which we are the lessor.  IFRIC 23 Uncertainty over Income Tax Treatments was issued in 2017 to clarify how to apply the recognition and measurement requiremen ts in IAS 12 Income Taxes when there is uncertainty over income tax treatments. It was required to be applied for annual periods commencing January 1, 2019, which for the Company was the annual period commencing September 1, 2019. The cumulative effect of the initial application of the new standard has been reflected as an adjustment to retained earnings at September 1, 2019. Refer to “Transition adjustments” below for details. c) Transition adjustments Below is the effect of transition to IFRS 16 and the adoption of IFRIC 23 on our condensed consolidated Statement of Financial Position as at September 1, 2019. (millions of Canadian dollars) As reported as at August 31, 2019 Effect of IFRS 16 transition Effect of IFRIC 23 transition Subsequent to transition as at September 1, 2019 ASSETS Current Cash 1,446 - - 1,446 Accounts receivable 287 - - 287 Inventories 86 - - 86 Other current assets 291 (16) - 275 Current portion of contract assets 106 - - 106 2,216 (16) - 2,200 Investments and other assets 37 - - 37 Property, plant and equipment 4,883 1,338 - 6,221 Other long-term assets 195 - - 195 Deferred income tax assets 4 - - 4 Intangibles 7,979 - - 7,979 Goodwill 280 - - 280 Contract assets 52 - - 52 15,646 1,322 - 16,968 LIABILITIES AND SHAREHOLDERS' EQUITY Current Short-term borrowings 40 - - 40 Accounts payable and accrued liabilities 1,015 - - 1,015 Provisions 224 - (5) 219 Income taxes payable 82 - (11) 71 Current portion of contract liabilities 223 - - 223 Current portion of long-term debt 1,251 - - 1,251 Current portion of lease liabilities - 113 - 113 2,835 113 (16) 2,932 Long-term debt 4,057 - - 4,057 Lease liabilities - 1,211 - 1,211 Other long-term liabilities 75 (2) - 73 Provisions 79 - - 79 Deferred credits 425 - - 425 Contract liabilities 15 - - 15 Deferred income tax liabilities 1,875 - 38 1,913 9,361 1,322 22 10,705 Shareholders' equity Common and preferred shareholders 6,282 - (22) 6,260 Non-controlling interests in subsidiaries 3 - - 3 6,285 - (22) 6,263 15,646 1,322 - 16,968 Prior to adopting IFRS 16, our total minimum operating lease commitments as at August 31, 2019 was $ 919 million. The weighted average discount rate applied to the total lease liabilities was 3.50 % at September 1, 2019. The difference between the total of the minimum lease payments set out in Note 27 in our 2019 Audited Financial Statements and the total lease liabil ity recognized on transition was a result of:  the inclusion of lease payments beyond minimum commitments relating to reasonably certain renewal periods or extension options that had not yet been exercised as at August 31, 2019;  the effect of discounting o n the minimum lease payments; and  certain costs to which we are contractually committed under lease contracts , but which do not qualify to be accounted for as a lease liability, such as variable lease payments not tied to an index or rate. d) Fiscal 2019 Accounting Policies Updated for IFRS 16 Leases The following accounting policy applies as of September 1, 2019 following the adoption of IFRS 16. Prior to September 1, 2019, IAS 17 was applied as disclosed in the Company’s 2019 annual consolidated financ ial statements, as permitted by transition provisions of IFRS 16. Leases are typically entered into for network infrastructure and equipment, including transponders, and land and buildings relating to the Company’s wireless and wireline networks, office s pace and retail stores. At inception of a contract, the Company assesses whether the contract contains a lease. A lease contract conveys the right to control the use of an identified asset for a period in exchange for consideration. To assess whether a con tract conveys the right to control the use of an identified asset, the Company assesses whether:  the contract involves the use of an identified asset;  the Company has the right to obtain substantially all of the economic benefits from use of the asset thro ughout the period of use; and  the Company has the right to direct the use of the identified asset. Lease liabilities are initially measured at the present value of future lease payments at the commencement date, discounted using the interest rate implicit in the lease or, if not readily determinable, the Company’s incremental borrowing rate. A single incremental borrowing rate is applied to a portfolio of leases with similar characteristics. Lease payments included in the measurement of the lease liability are comprised of:  Fixed payments, including in-substance fixed payments;  Variable lease payments that depend on an index or rate;  Amounts expected to be payable under a residual value guaran tee; and  Payments relating to purchase options and renewal option periods that are reasonably certain to be exercised, or periods subject to termination options that are not reasonably certain to be exercised. The initial lease term included in the measurement of the lease liability is comprised of:  The non-cancellable period of the lease;  Periods covered by options to extend the lease, where the Company is reasonably certain to exercise the option; and  Periods covered by options to terminate the lea se, where the Company is reasonably certain not to exercise the option. Lease liabilities are subsequently measured at amortized cost. Lease liabilities are remeasured when there is a lease modification, and a corresponding adjustment is made to the carry ing amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. The interest expense for lease liabilities is recorded in Interest expense in the Consolidated Statements of In come. Variable lease payments that do not depend on an index or rate are not included in the measurement of lease liabilities and right-of-use assets. The related payments are expensed in Operating, general and administrative expenses in the period in whi ch the event or condition that triggers those payments occurs. Right-of-use assets are initially measured at cost, which comprises the initial amount of the lease obligation adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred, plus an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received. The Company presents right-of-use assets in Pr operty, plant and equipment. If we obtain ownership of the leased asset by the end of the lease term or the costs of the right-of-use asset reflects the exercise of a purchase option, we depreciate the right-of-use asset from the lease commencement date t o the end of the useful life of the underlying asset. Otherwise, right-of-use assets are depreciated on a straight-line basis from the commencement date to the earlier of the end of the useful life or the end of the lease term. Right-of-use assets are peri odically reduced by impairment losses, if any, and adjusted for certain remeasurements on the related lease liability. The depreciation charge for right-of-use assets is recorded in Amortization – Property, plant and equipment. Significant Judgments and E stimates The application of IFRS 16 requires the Company to make judgments that affect the valuation of the lease liabilities and the valuation of right-of-use assets. These include determining whether a contract contains a lease, determining the contract term, including whether or not to exercise renewal or termination options, and determining the interest rate used for discounting future cash flows.

Business Segment Information	3. BUSINESS SEGMENT INFORMATION The Company’s chief operating decision makers are the Chief Executive Officer, the President and the Executive Vice President, Chief Financial & Corporate Development Officer and they review the operating performance of the Company by segments , which are comprised of Wireline and Wireless. The chief operating decision makers utilize adjusted earnings before interest, income taxes, depreciation and amortization (“ EBITDA”) for each segment as a key measure in making operating decisions an d assessing performance. The Wireline segment provides Cable telecommunications services including Video, Internet, Wi-Fi, Phone, Satellite Video and data networking through a national fibre-optic backbone network to Canadian consumers, North American bu sinesses and public-sector entities. The Wireless segment provides wireless services for voice and data communications serving customers in Ontario, British Columbia and Alberta. Both of the Company’s reportable segments are substantially located in Cana da.

Fair Value

Fair Value [Abstract]
Fair Value	1 5 . FAIR VALUE Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, ther efore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Financial instruments The fair value of financial instruments has been determined as follows: (i) Current assets and current liabilities The fa ir value of financial instruments included in current assets and current liabilities approximates their carrying value due to their short-term nature. (ii) Investments and other assets and other long-term assets The fair value of publicly traded investm ents is determined by quoted market prices. Investments in private entities which do not have quoted market prices in an active market and whose fair value cannot be readily measured are carried at approximate fair value . No published market exists for suc h investments. These equity investments have been made as they are considered to have the potential to provide future benefit to the Company and accordingly, the Company has no current intention to dispose of these investments in the near term. The fair va lue of long-term receivables approximates their carrying value as they are recorded at the net present values of their future cash flows, using an appropriate discount rate. (iii) Long-term debt The carrying value of long-term debt is at amortized cost b ased on the initial fair value as determined at the time of issuance or at the time of a business acquisition. The fair value of publicly traded notes is based upon current trading values. The fair value of finance lease obligations is determined by discou nting future cash flows using a rate for loans with similar terms, conditions and maturity dates. The carrying value of bank credit facilities approximates fair value as the debt bears interest at rates that fluctuate with market values. Other notes and de bentures are valued based upon current trading values for similar instruments. The carrying value and estimated fair value of long-term debt are as follows: February 29, 2020 August 31, 2019 Carrying value Estimated fair value Carrying value Estimated fair value Liabilities Long-term debt (including current portion) (1) 4,051 4,839 5,308 6,014 (1) Level 2 fair value – determined by valuation techniques using inputs based on observable market data, either directly or indirectly, other than quoted prices. (iv) Other long-term liabilities The fair value of contingent consideration arising from a business acquisition is determined by calculating the present value of the probability weighted assessment of the likelihood that revenue targets will be met and the estimated timing of such payments. (v) Derivative financial instruments The fair value of US currency forward purchase contracts is determined by an est imated credit-adjusted mark-to-market valuation using observable forward exchange rates at the end of reporting periods and contract forward rates. During the quarter, the Company entered into a cross-currency interest rate swap with a member of the Comp any’s lending syndicate with a notional amount of $ 34 USD for a term of one month . The swap requires that funds are exchanged back in one month at the same terms unless both parties agree to extend the swap for an additional month. By borrowing in US dol lars, the Company may access lower interest rates. The swap mitigates the risk of changes in the value of the US Dollar LIBOR borrowings as it will be exchanged for the same Canadian equivalent in one month. The swap is not designated as a hedge for acco unting purposes. The fair value of this cross-currency interest rate swap at February 29, 2020 is $ nil and is determined by an estimated credit-adjusted mark-to-market valuation using observable forward exchange rates at the end of reporting periods and co ntract forward rates.

Intangibles And Goodwill [Abstract]
Intangibles And Goodwill	1 6 . INTANGIBLES AND GOODWILL Impai rment testing of indefinite-life intangibles and goodwill The Company conducted its annual impairment test on goodwill and indefinite-life intangibles as at February 1, 20 20 and the recoverable amount of the cash generating units exceeded their carrying value. A hypothetical decline of 10 % in the recoverable amount of the broadcast rights and licences for the Cable cash generating unit as at February 1, 20 20 would not result in any impairment loss. A hypothetical decline of 10 % in the recoverable amount of the broadcast rights and licences for the Satellite cash generating unit as at February 1, 20 20 would not result in an impairment loss. A hypothetical decline of 10 % in the recoverable amount of the Wireless gene rating unit as at February 1, 20 20 would not result in any impairment loss. Any changes in economic conditions since the impairment testing conducted as at February 1, 20 20 do not represent events or changes in circumstance that would be indicative of impairment at February 2 9 , 20 20 . Significant estimates inherent to this analysis include discount rates and the terminal value. At February 1, 20 20 , the estimates that have been utilized in the impairment tests reflect any changes in market conditions and are as follows: Terminal value Post-tax discount rate Terminal growth rate Terminal adjusted EBITDA multiple Cable 6.0% 0.5% 8.0x Satellite 7.0% -4.0% 6.7x Wireless 7.0% 1.0% 5.3x A sensitivity analysis of significant estimates is conducted as part of every impairment test. With respect to the impairment tests performed in the second quarter, the estimated decline in recoverable amount for the sensitivity of significant estim ates is as follows: Estimated decline in recoverable amount Terminal value 1% increase in discount rate 1% decrease in terminal growth rate 0.5 times decrease in terminal adjusted EBITDA multiple Cable 15.0% 12.5% 6.2% Satellite 7.8% 5.5% 7.4% Wireless 18.2% 10.1% 9.4%

Subsequent Events [Abstract]
Subsequent Events	17. SUBSEQUENT EVENTS Subsequent to February 29, 2020, the World Health Organization (WHO) declared COVID-19 a pandemic. In response to the WHO declaration and continuing spread of COVID-19, several social distancing measures taken by the Company and third parties including governments, reg ulatory authorities, businesses and our customers that could negatively impact the Company’s operations and financial results in future periods. Given the unprecedented and pervasive impact of changing circumstances surrounding the COVID-19 pandemic , there is inherently more uncertainty associated with our future operating assumptions and expectations as compared to prior periods. As such, it is not possible to estimate the impacts COVID-19 will have on the Company’s financial position or results of operati ons in future periods. While the direct impacts of COVID-19 are not determinable at this time, the Company has available liquidity of $ 1. 5 billion and a certain degree of flexibility in its operating and investing plans to mitigate the impacts of COVID-19. Subsequent to February 29, 2020, the Company drew an additional $200 under its credit facility to add to its existing cash balance as at February 29, 2020.

Statement Of Compliance	Statement of compliance These condensed interim consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) and in compliance with International Accounting Standard (“IAS”) 34 Interim Financial Report ing as issued by the International Accounting Standards Board (“IASB”). The condensed interim consolidated financial statements of the Company for the three and six months ended February 29 , 20 20 were authorized for issue by the Board of Di rectors on April 9 , 20 20 .
Basis Of Presentation	Basis of presentation These condensed interim consolidated financial statements have been prepared primarily under the historical cost convention except as detailed in the significant accounting policies disclosed in the Compa ny’s consolidated financial statements for the year ended August 31, 201 9 and are expressed in millions of Canadian dollars unless otherwise indicated. The condensed interim consolidated statements of income are presented using the nature classification fo r expenses. Certain comparative figures have been reclassified to conform to the current period’s presentation. The notes presented in these condensed interim consolidated financial statements include only significant events and transactions occurring s ince the Company’s last fiscal year end and are not fully inclusive of all matters required to be disclosed by IFRS in the Company’s annual consolidated financial statements. As a result, these condensed interim consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended August 31, 201 9 . The condensed interim consolidated financial statements follow the same accounting policies and methods of application as the most recent annual c onsolidated financial statements except as noted below.
New Accounting Standards	New accounting standards We adopted the following new accounting standards effective September 1, 2019.  IFRS 16 Leases was issued on January 2016 and replaces IAS 17 Leases . The new standard requires entities to recognize lease assets and lease obligations on the balance sheet. For lessees, IFRS 16 removes the classification of leases as either operating leases or finance leases, instead requiring that leases be capitalized by recognizing the present value of the lease payments and showing them as lease assets (right-of-use assets) and representing the right to use the underlying leased asset. If lease payments are made over time, the Company recognize s a lease liability repr esenting its obligation to make future lease payments. Certain short-term leases (less than 12 months) and leases of low value may be exempted from the requirements and may continue to be treated as operating leases if certain elections are made. Lessors w ill continue with a dual lease classification model. Classification will determine how and when a lessor will recognize lease revenue, and what assets would be recorded. As a result of adopting IFRS 16, the Company recognized a significant increase to bo th assets and liabilities on our Consolidated Statements of Financial Position as well as a decrease to operating costs, as a result of removing the lease expense, an increase to depreciation and amortization, due to the depreciation of the right-of-use as set, and an increase to finance costs, due to the accretion of the lease liability. Relative to the results of applying the previous standard, although actual cash flows are unaffected, the Company’s statement of cash flows will reflect increases in cash f lows from operating activities offset equally by decreases in cash flows from financing activities. Implementation We adopted IFRS 16 using a modified retrospective approach whereby the financial statements of prior periods presented are not restated. We recognized lease liabilities at September 1, 2019 for leases previously classified as operating leases, measured at the present-value of the lease payments using our incremental borrowing rate at that date, with the corresponding right-of-use asset generally measured at an equal amount, adjusted for any prepaid or accrued rent outstanding as at August 31, 2019. As perm itted by IFRS 16, we applied certain practical expedients to facilitate the initial adoption and ongoing application of IFRS 16 including the following:  not separate fixed non-lease components from lease components for certain classes of underlying assets. Each lease component and any associated non-lease components will be accounted for as a single lease component;  apply a single discount rate to a portfolio of leases with similar characteristics;  exclude initial direct costs from measuring the right-of-us e asset as at September 1, 2019; and  use hindsight in determining the lease term where the contract contains purchase, extension, or termination options. On transition, we have not elected the recognition exemptions on short-term leases or low-value leases; however, we may choose to elect these recognition exemptions on a class-by-class basis for new classes and on a lease-by-lease basis, respectively, in the future. In December 2019 , the IFRS Interpretations Committee issued a final agenda decision in regards to the determination of the lease term for cancellable or renewable leases under IFRS 16. The Company is currently assessing the im pact of this interpretation on its financial . There was no significant impact for contracts in which we are the lessor.  IFRIC 23 Uncertainty over Income Tax Treatments was issued in 2017 to clarify how to apply the recognition and measurement requiremen ts in IAS 12 Income Taxes when there is uncertainty over income tax treatments. It was required to be applied for annual periods commencing January 1, 2019, which for the Company was the annual period commencing September 1, 2019. The cumulative effect of the initial application of the new standard has been reflected as an adjustment to retained earnings at September 1, 2019. Refer to “Transition adjustments” below for details.

The weighted average discount rate applied to the total lease liabilities was 3.50 % at September 1, 2019. The difference between the total of the minimum lease payments set out in Note 27 in our 2019 Audited Financial Statements and the total lease liabil ity recognized on transition was a result of:  the inclusion of lease payments beyond minimum commitments relating to reasonably certain renewal periods or extension options that had not yet been exercised as at August 31, 2019;  the effect of discounting o n the minimum lease payments; and  certain costs to which we are contractually committed under lease contracts , but which do not qualify to be accounted for as a lease liability, such as variable lease payments not tied to an index or rate.
Fiscal 2019 Accounting Policies Updated for IFRS 16	Fiscal 2019 Accounting Policies Updated for IFRS 16 Leases The following accounting policy applies as of September 1, 2019 following the adoption of IFRS 16. Prior to September 1, 2019, IAS 17 was applied as disclosed in the Company’s 2019 annual consolidated financ ial statements, as permitted by transition provisions of IFRS 16. Leases are typically entered into for network infrastructure and equipment, including transponders, and land and buildings relating to the Company’s wireless and wireline networks, office s pace and retail stores. At inception of a contract, the Company assesses whether the contract contains a lease. A lease contract conveys the right to control the use of an identified asset for a period in exchange for consideration. To assess whether a con tract conveys the right to control the use of an identified asset, the Company assesses whether:  the contract involves the use of an identified asset;  the Company has the right to obtain substantially all of the economic benefits from use of the asset thro ughout the period of use; and  the Company has the right to direct the use of the identified asset. Lease liabilities are initially measured at the present value of future lease payments at the commencement date, discounted using the interest rate implicit in the lease or, if not readily determinable, the Company’s incremental borrowing rate. A single incremental borrowing rate is applied to a portfolio of leases with similar characteristics. Lease payments included in the measurement of the lease liability are comprised of:  Fixed payments, including in-substance fixed payments;  Variable lease payments that depend on an index or rate;  Amounts expected to be payable under a residual value guaran tee; and  Payments relating to purchase options and renewal option periods that are reasonably certain to be exercised, or periods subject to termination options that are not reasonably certain to be exercised. The initial lease term included in the measurement of the lease liability is comprised of:  The non-cancellable period of the lease;  Periods covered by options to extend the lease, where the Company is reasonably certain to exercise the option; and  Periods covered by options to terminate the lea se, where the Company is reasonably certain not to exercise the option. Lease liabilities are subsequently measured at amortized cost. Lease liabilities are remeasured when there is a lease modification, and a corresponding adjustment is made to the carry ing amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. The interest expense for lease liabilities is recorded in Interest expense in the Consolidated Statements of In come. Variable lease payments that do not depend on an index or rate are not included in the measurement of lease liabilities and right-of-use assets. The related payments are expensed in Operating, general and administrative expenses in the period in whi ch the event or condition that triggers those payments occurs. Right-of-use assets are initially measured at cost, which comprises the initial amount of the lease obligation adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred, plus an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received. The Company presents right-of-use assets in Pr operty, plant and equipment. If we obtain ownership of the leased asset by the end of the lease term or the costs of the right-of-use asset reflects the exercise of a purchase option, we depreciate the right-of-use asset from the lease commencement date t o the end of the useful life of the underlying asset. Otherwise, right-of-use assets are depreciated on a straight-line basis from the commencement date to the earlier of the end of the useful life or the end of the lease term. Right-of-use assets are peri odically reduced by impairment losses, if any, and adjusted for certain remeasurements on the related lease liability. The depreciation charge for right-of-use assets is recorded in Amortization – Property, plant and equipment. Significant Judgments and E stimates The application of IFRS 16 requires the Company to make judgments that affect the valuation of the lease liabilities and the valuation of right-of-use assets. These include determining whether a contract contains a lease, determining the contract term, including whether or not to exercise renewal or termination options, and determining the interest rate used for discounting future cash flows.
