Summary of significant accounting policies
Summary of significant accounting policies	Summary of significant accounting policies (a) Basis of presentation Our consolidated financial statements are expressed in United States dollars. The generally accepted accounting principles that we use are International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS-IASB). Generally accepted accounting principles require that we disclose the accounting policies we have selected in those instances where we have been obligated to choose from among various generally accepted accounting principle-compliant accounting policies. In certain other instances, including where no selection among policies is allowed, we are also required to disclose how we have applied certain accounting policies. In our assessment, all of our required accounting policy disclosures are not equally significant for us, as set out in the accompanying table; their relative significance to us will evolve over time as we do. In the fourth quarter of 2022, the Company changed its presentation of cash interest paid on credit facilities in the consolidated statements of cash flows, which was previously included in cash flows from operating activities, and has been reclassified to cash flows from financing activities, as permitted by IAS 7, Statement of cash flows . Cash interest paid relates to interest paid on the Company’s long-term debt, which were drawn primarily to fund prior acquisitions. We believe this provides a more relevant presentation of operating cash flows, as it reflects cash flows generated by the business before deducting costs associated with servicing our long-term debt, such as interest. The table below summarizes the effect of this change in presentation, which had no impact on operating income, net income, or cash and cash equivalents. Years Ended December 31 (millions) 2021 2020 Cash provided by operating activities, as previously reported $ 282 $ 263 Add back: Interest paid 29 34 Cash provided by operating activities $ 311 $ 297 Cash (used in) provided by financing activities, as previously reported $ (206) $ 1,691 Less: Interest paid (29) (34) Cash (used in) provided by financing activities $ (235) $ 1,657 In our consolidated statements of financial position, we have also reclassified certain current and non-current liabilities and grouped these amounts in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, as they are not individually material to these consolidated financial statements. All amounts presented for the comparative period has been reclassified to conform with current period presentation. These consolidated financial statements were authorized by our Board of Directors fo r issue on February 9, 2023 .

Our principal subsidiaries are: TELUS International (U.S.) Corp.; Xavient Digital LLC; CallPoint New Europe EAD; TELUS International Services Limited; TELUS International Philippines Inc.; Voxpro Limited; TELUS International Germany GmbH; and TELUS International AI Inc. Our financing arrangements and those of our subsidiaries do not impose restrictions on inter-corporate dividends, but external dividends are restricted based upon total net debt to earnings before interest, income taxes, depreciation and amortization (EBITDA) ratios, all as defined by our financing arrangements. On a continuing basis, we review our corporate organization and effect changes as appropriate so as to enhance the value of TELUS International. This process can, and does, affect which of our subsidiaries are considered principal subsidiaries at any particular point in time. (c) Use of estimates and judgments The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates, assumptions and judgments that affect: the reported amounts of assets and liabilities at the date of the financial statements; the disclosure of contingent assets and liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates Examples of the estimates and assumptions that we make and their relative significance and degree of difficulty are as follows: Judgments Examples of our use of judgment, apart from those involving estimation, include the following: • Assessments about whether line items are sufficiently material to warrant separate presentation in the primary financial statements and, if not, whether they are sufficiently material to warrant separate presentation in the financial statement notes. In the normal course, we make changes to our assessments regarding presentation materiality so that they reflect current economic conditions. Due consideration is given to the view that it is reasonable to expect differing opinions of what is, and is not, material. • In respect of revenue-generating transactions, generally we must make judgments that affect the timing of the recognition of revenue as it relates to assessing when we have satisfied our performance obligations to our customers, either at a point in time or over a period of time. • The preparation of our financial statements in accordance with generally accepted accounting principles requires management to make judgments that affect the financial statement disclosure of information regularly reviewed by our chief operating decision maker used to make resource allocation decisions and to assess performance, as further discussed in Note 22—Segment Reporting . A significant judgment we make is that our cash flows are sufficiently indistinguishable given our global operating model, resulting in a single operating and reporting segment. • Determination of the functional currency of each subsidiary involves significant judgment. The determination of functional currency affects the carrying value of non-current assets included in the statement of financial position and, as a consequence, the amortization of those assets, as well as the exchange gains and losses recorded in the consolidated statement of comprehensive income and the consolidated statement of equity. • The decision to depreciate and amortize any property, plant, equipment and intangible assets that are subject to amortization on a straight-line basis, as we believe that this method reflects the consumption of resources related to the economic lifespan of those assets better than an accelerated method and is more representative of the economic substance of the underlying use of those assets. • In connection with the annual impairment testing of goodwill, there are instances where we must exercise judgment in the determination of our cash generating unit. A significant judgment that we make is that each geographic area in which we operate is insufficiently distinct, making it impractical to objectively distinguish the cash flows of each region. As such, each region is not an individual cash generating unit. • In respect of claims and lawsuits, as discussed further in Note 17(b)—Contingent liabilities—Claims and lawsuits , the determination of whether an item is a contingent liability or whether an outflow of resources is probable and thus needs to be accounted for as a provision. (d) Financial instruments—recognition and measurement In respect of the recognition and measurement of financial instruments, we have adopted the following policies: • Derivatives that are part of an established and documented cash flow hedging relationship are accounted for as held for hedging. We believe that classification as held for hedging results in a better matching of the change in the fair value of the derivative financial instrument with the risk exposure being hedged. • Derivatives that are not part of a documented cash flow hedging relationship are accounted for as held for trading and thus are measured at fair value through net income. • Transaction costs, other than in respect of items held for trading, are added to the initial fair value of the acquired financial asset or financial liability. We have selected this method as we believe that it results in a better matching of the transaction costs with the periods in which we benefit from the transaction costs. (e) Hedge accounting Hedge accounting The purpose of hedge accounting, in respect of our designated hedging relationships, is to ensure that counterbalancing gains and losses are recognized in the same periods. We have chosen to apply hedge accounting as we believe that it is more representative of the economic substance of the underlying transactions. In order to apply hedge accounting, a high correlation (which indicates effectiveness) is required in the offsetting changes in the risk-associated values of the financial instruments (the hedging items) used to establish the designated hedging relationships and all, or a part, of the asset, liability or transaction having an identified risk exposure that we have taken steps to modify (the hedged items). We assess the anticipated effectiveness of designated hedging relationships at inception and their actual effectiveness for each reporting period thereafter. We consider a designated hedging relationship to be effective if the following critical terms match between the hedging item and the hedged item: the notional amount of the hedging item and the principal amount of the hedged item; maturity dates; payment dates; and interest rate index (if, and as, applicable). Any ineffectiveness, such as would result from a difference between the notional amount of the hedging item and the principal amount of the hedged item, or from a previously effective designated hedging relationship becoming ineffective, is reflected in the consolidated statements of income and other comprehensive income as Interest expense if in respect of long-term debt, or as Goods and services purchased if in respect of future purchase commitments. Hedging assets and liabilities In the application of hedge accounting, an amount (the hedge value) is recorded in the consolidated statement of financial position in respect of the fair value of the hedging items. The net difference, if any, between the amounts recognized in the determination of net income and the amounts necessary to reflect the fair value of the designated cash flow hedging items recorded in the consolidated statement of financial position is recognized as a component of Other comprehensive income. In the application of hedge accounting to the finance costs arising from interest paid on our long-term debt, the amount recognized in the determination of net income is the amount that counterbalances the difference between interest calculated at a variable interest rate, and the fixed interest rate as per our credit facility. (f) Revenue recognition General Our solutions involve delivery of multiple services and products that occur at different points in time and/or over different periods of time. These arrangements may contain multiple performance obligations and the transaction price is measured and allocated among the performance obligations based upon their relative stand-alone selling price. Our relevant revenue recognition policies are then applied to the performance obligations. Multiple contracts with a single customer are normally accounted for as separate arrangements. In instances where multiple contracts are entered into with a customer in a short period of time, the contracts are reviewed as a group to ensure that, as with multiple performance obligation arrangements, their relative stand-alone selling prices are appropriate. Our revenues are recorded net of any value-added and/or sales taxes billed to the customer concurrent with a revenue-generating transaction. Discounts and rebates are recorded as a reduction to revenue rather than as an expense. We recognize revenues for each accounting period as services are provided, based on fees earned per-productive hour or per transaction. Fees are invoiced to customers on a regular basis. Advance billings are recorded when a billing occurs prior to provision of the associated services; such advance billings are recognized as revenue in the period in which the services are provided. (g) Depreciation, amortization and impairment Depreciation and amortization Property, plant, and equipment, including right-of-use lease assets, are depreciated on a straight-line basis over their estimated useful lives. Depreciation includes amortization of right-of-use lease assets and amortization of leasehold improvements. Leasehold improvements are normally amortized over the lesser of their expected average service life or the term of the lease. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives, which are reviewed at least annually and adjusted as appropriate. Estimated useful lives for our property, plant and equipment and right-of-use assets subject to depreciation are as follows: Estimated Computer hardware and network assets 2 to 10 years Buildings and leasehold improvements 5 to 20 years Furniture and equipment 3 to 7 years Right-of-use lease assets 3 to 20 years Estimated useful lives for our intangible assets subject to amortization are as follows: Estimated Customer contracts and related customer relationships 4 to 15 years Software 3 to 7 years Brand 3 years Standard operating procedures 5 years Crowdsource assets 8 years Impairment—general Impairment testing compares the carrying values of the assets or cash generating units being tested with their recoverable amounts (the recoverable amount being the greater of an asset’s value-in-use or its fair value less costs to sell). Impairment losses are immediately recognized, to the extent that the carrying value of an asset exceeds its recoverable amount. Should the recoverable amounts for impaired assets subsequently increase, the impairment losses previously recognized (other than in respect of goodwill) may be reversed to the extent that the reversal is not a result of “unwinding the discount” and that the resulting carrying values do not exceed the carrying values that would have been the result if no impairment losses had been previously recognized. Impairment—property, plant and equipment; intangible assets subject to amortization In our assessment of estimated useful lives of assets, we consider such items as the timing of technological obsolescence, competitive pressures and future infrastructure utilization plans. These considerations could indicate that the carrying value of an asset may not be recoverable. If the carrying value of an asset were not considered recoverable, an impairment loss is recorded. Impairment—goodwill We assess the carrying value of goodwill each period for indicators of impairment, and an impairment test is performed when an indicator exists. At a minimum, goodwill is tested annually for impairment on October 1. We assess our goodwill by comparing the recoverable amount of our business to its carrying value. To the extent that the carrying value exceeds its recoverable amount, the excess amount is recorded as an impairment charge in the period. (h) Translation of foreign currencies Trade transactions completed in foreign currencies are translated into United States dollars at the rates of exchange prevailing at the time of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into United States dollars at the rate of exchange in effect at the statement of financial position date, with any resulting gain or loss recorded to Foreign exchange in the consolidated statement of income and other comprehensive income. We have foreign subsidiaries that do not have the United States dollar as their functional currency. Foreign exchange gains and losses arising from the translation of these foreign subsidiaries’ accounts into United States dollars are reported as a component of other comprehensive income. (i) Income and other taxes We follow the liability method of accounting for income taxes. Under this method, current income taxes are recognized for the estimated income taxes payable for the current year. Deferred income tax assets and liabilities are recognized for temporary differences between the tax and accounting bases of assets and liabilities, and also for the benefit of losses available to be carried forward to future years for tax purposes that are more likely than not to be realized. The amounts recognized in respect of deferred income tax assets and liabilities are based upon the expected timing of the reversal of temporary differences or usage of tax losses and application of the substantively enacted tax rates at the time of reversal or usage. We account for any changes in substantively enacted income tax rates affecting deferred income tax assets and liabilities in full in the period in which the changes are substantively enacted. We account for changes in the estimates of tax balances for prior years as estimate revisions in the period in which the changes in estimates arise; we have selected this approach as its emphasis on the statement of financial position is more consistent with the liability method of accounting for income taxes. Our operations are complex and the related domestic and foreign tax interpretations, regulations, legislation and jurisprudence are continually changing. As a result, there are usually some tax matters in question that result in uncertain tax positions. We recognize the income tax benefit of an uncertain tax position when it is more likely than not that the ultimate determination of the tax treatment of the position will result in that benefit being realized; however, this does not mean that tax authorities cannot challenge these positions. We accrue an amount for interest charges on current tax liabilities that have not been funded, which would include interest and penalties arising from uncertain tax positions. We include such charges in the consolidated statement of income and other comprehensive income as a component of income tax expense. (j) Share-based compensation General Share-based compensation awards issued to certain of our employees include phantom and equity restricted share units, and phantom and equity share options. We recognize a share-based compensation expense in respect of these plans based on the fair value of the awards. Generally, the compensation expense of the award is recognized on a straight-line basis over the vesting of the award subject to continued service with us through the vesting date. A compensation expense is recognized for awards containing performance conditions only to the extent that it is probable that those performance conditions will be met and based on the expected achievement factor. Adjustments are made to reflect expected and actual forfeitures during the vesting period due to failure to satisfy service conditions or performance conditions against the original compensation expense recognized. Restricted share units Restricted share units are accounted for as equity instruments if they will be equity-settled, or liability instruments if they will be cash-settled. For equity-accounted awards, we recognize and measure compensation expense based on the grant date fair value, which is determined to be equal to the market price of one TELUS International subordinate voting share or TELUS Corporation common share. Fair value is not subsequently re-measured unless the conditions on which the award was granted are modified. For liability-accounted awards, we accrue a liability equal to the product of the number of vesting restricted share units multiplied by the market price of one TELUS International subordinate voting share at the end of the reporting period. A mark-to-market adjustment is recorded each period based on changes in the market price of shares. Share option awards Share option awards are accounted for as equity instruments if they will be equity-settled, or liability instruments if they are cash-settled. For equity-accounted awards, we recognize and measure compensation expense based on the grant date fair value, which is determined using the Black-Scholes option pricing model. Fair value is not subsequently re-measured unless the conditions on which the award was granted are modified. Proceeds arising from the exercise of equity-accounted share option awards are recognized as an increase to share capital, as are the recognized grant-date fair values of the exercised share option awards. For liability-accounted awards, we recognize and measure compensation expense based on the fair value of the award at the end of each reporting period, which is determined using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of certain assumptions, some of which are highly subjective, including the expected volatility of the price of our common shares, the expected term of the option and the expected dividend yield of our shares. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our share-based compensation expense could be materially different in future periods. (k) Employee future benefit plans The Company records annual amounts relating to its defined benefit plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, compensation increase and turnover rates. When the defined benefit plan’s key assumptions fluctuate relative to their immediately preceding year-end values, such actuarial gains or losses are recognized in other comprehensive income. We participate in defined benefit pension plans that share risks between TELUS Corporation and its subsidiaries as well as unfunded, non-contributory retirement plans of TELUS International and its subsidiaries. TELUS Corporation’s policy is to charge us our participant-based net defined benefit pension cost, as measured in accordance with IAS 19 , Employee Benefits , which are actuarially determined using the accrued benefit method pro-rated on service and management’s best estimates of salary escalation and the retirement ages of employees. In the determination of net income, net interest for each plan, which is the product of the plan’s surplus (deficit) multiplied by the discount rate, is included as a component of Interest expense. Contributions to defined contribution plans are charged to the consolidated statements of income in the period in which services are rendered by the covered employees. (l) Cash and cash equivalents Cash and cash equivalents includes short-term investments in money market funds and other highly liquid, low-risk instruments with maturities of less than three months. Cash and cash equivalents are presented net of outstanding items, including cheques written but not cleared by the related banks as at the statement of financial position date. (m) Property, plant and equipment; intangible assets Property, plant and equipment (excluding right-of-use assets) are recorded at historical cost. Self-constructed property, plant and equipment assets includes materials, direct labour and applicable overhead costs. Right-of-use assets, which are included in property, plant and equipment, are initially measured at cost, which includes the amount of lease liabilities recognized at the inception of the lease, initial direct costs incurred, and lease payments made at or before the lease commencement date less any lease incentives received. Subsequent to the initial recognition, right-of-use assets may be adjusted for any re-measurement of the corresponding lease liabilities. Intangible assets are recorded at historical cost. For internally-developed internal-use software, the historical cost recorded includes materials, direct labour and direct labour-related costs. (n) Lease liabilities Lease liabilities are initially measured at the present value of lease payments to be made over the expected lease term. Lease payments include fixed payments, less any lease incentives or discounts. The expected lease term is the non-cancellable term of the lease, together with any periods covered by an option to extend the lease if it is reasonably certain to be exercised, considering all relevant factors and terms of the lease arrangement. In calculating the present value of lease payments, we use the interest rate implicit in the lease, if that rate can be readily determined, otherwise we use our incremental borrowing rate based on a similar security, term and economic environment. Subsequent to the initial recognition, we monitor for significant events or changes in circumstances that would require a change in the expected lease term, including a modification to the lease, and adjust the lease liability accordingly based on the change in present value of lease payments. (o) Business combinations We use the acquisition method to account for business combinations, under which we allocate the excess of the purchase price of business acquisitions over the fair value of identifiable net assets acquired to goodwill. The purchase price is determined as the fair value of assets transferred, liabilities assumed, or equity instruments issued on the date of exchange, which may include contingent considerations that are initially measured at fair value at the acquisition date. Subsequent changes to the fair value of any contingent considerations are recognized through profit or loss. Acquisition-related costs are expensed as incurred. For intangible assets acquired, the fair value is generally derived from a valuation analysis prepared by management or third-party experts as needed, based on appropriate valuation techniques using a forecast of the total expected future net cash flows and closely linked to the assumptions made by management regarding the future performance of the assets concerned and the discount rate applied. Where other markets or market participants are readily observable, these are considered in the determination of fair value. If the fair values of the assets, liabilities and contingent liabilities can only be calculated on a provisional basis, the business combination is recognized initially using provisional values. Any adjustments resulting from the completion of the measurement process are recognized within twelve months of the date of acquisition. Business transfers from related parties are accounted for as common control transactions using the predecessor accounting method wherein no assets or liabilities acquired are restated to their fair values and the results of operations include the transferred businesses’ results only from the date of our acquisition of them. No goodwill, except to the extent transferred as part of the transaction, is recognized on such transactions, and any excess purchase price is recorded as an adjustment to owners’ equity.

Accounting policy developments
Accounting policy developments	Accounting policy developments Standards, interpretations and amendments to standards not yet effective and not yet applied In February 2021, the International Accounting Standards Board issued narrow-scope amendments to IAS 1, Presentation of Financial Statements , IFRS Practice Statement 2, Making Materiality Judgements and IAS 8, Accounting Polices, Changes in Accounting Estimates and Errors . The amendments are effective for annual periods beginning on or after January 1, 2023, although earlier application is permitted. The amendments will require the disclosure of material accounting policy information rather than disclosing significant accounting policies and clarify how to distinguish changes in accounting policies from changes in accounting estimates. Based on our current assessment, we do not expect that our financial disclosure will be materially affected by the application of the amendments. In May 2021, the International Accounting Standards Board issued targeted amendments to IAS 12, Income Taxes. The amendments are effective for annual periods beginning on or after January 1, 2023, although earlier application is permitted. With a view to reducing diversity in reporting, the amendments will clarify that companies are required to recognize deferred taxes on transactions where both assets and liabilities are recognized, such as with leases and asset retirement (decommissioning) obligations. Based upon our current facts and circumstances, we do not expect our financial performance or disclosure to be materially affected by the application of the amended standard.

Disclosure of objectives, policies and processes for managing capital [abstract]
Capital structure financial policies	Capital structure financial policies Our objective when managing capital is to maintain a flexible capital structure that optimizes the cost and availability of capital at acceptable risk levels. In the management of capital and in its definition, we include owners’ equity (excluding accumulated other comprehensive income), long-term debt (including long-term credit facilities and any hedging assets or liabilities associated with our long-term debt, net of amounts recognized in accumulated other comprehensive income and excluding lease liabilities) and cash and cash equivalents. We manage capital by monitoring the financial covenants in our credit facility ( Note 16—Share capital ). We manage our capital structure and make adjustments to it in light of changes in economic conditions and the risk characteristics of our business. In order to maintain or adjust our capital structure, we may issue new shares, issue new debt with different terms or characteristics, which may be used to replace existing debt, or pay down our debt balance with cash flows from operations. On February 3, 2021, we completed our IPO and issued 21.0 million subordinate voting shares at $25.00 per shar e. Net cash proceeds were used to repay a portion of outstanding borrowings under our credit agreement. On December 20, 2022, we amended and expanded our total credit facility to $2.0 billion, comprised of an $800 million revolving component, and amortizing $1.2 billion term loan component, now maturing on January 3, 2028 (see Note 15(b)—Long-term debt—Credit facility for additional details).

Share-based compensation	Share-based compensation (a) Rest ricted share unit plan Restricted share units We have various restricted share unit award types, including equity-accounted restricted share units (RSUs) and performance restricted share units (PSUs), and liability-accounted restricted share units (Phantom RSUs) and performance restricted share units (Phantom PSUs). All restricted share units are nominally equal in value to one TELUS International subordinate voting share, and liability-accounted restricted share units are settled in cash. All restricted share units granted for the years ended December 31, 2022 and 2021 were equity-accounted RSUs, whereas all restricted share units granted prior to December 31, 2020 were liability-accounted Phantom RSUs or Phantom PSUs. The following table presents a summary of the activity related to our restricted share units: US$ denominated Number of units Weighted average grant-date Non-vested Vested Outstanding, January 1, 2020 2,101,733 — $ 6.70 Granted 357,966 — 11.11 Vested (982,395) 982,395 6.51 Exercised — (982,395) 6.51 Forfeited (93,662) — 7.12 Outstanding, December 31, 2020 1,383,642 — 7.94 Granted 1,383,983 — 27.26 Vested (805,429) 805,429 7.29 Exercised (1) — (805,429) 7.29 Forfeited (111,389) — 20.16 Outstanding, December 31, 2021 1,850,807 — 21.94 Granted 821,223 59,512 26.41 Vested (798,373) 798,373 16.63 Exercised (1) — (857,885) 17.52 Forfeited (267,836) — 19.85 Outstanding, December 31, 2022 1,605,821 — $ 27.10 ______________________________________________ (1) During the year ended December 31, 2022, 360,044 RSUs and PSUs (2021 - 32,244 RSUs) were exercised and settled with subordinate voting shares issued from treasury, and 497,841 Phantom RSUs and Phantom PSUs (2021 - 773,185 Phantom RSUs and Phantom PSUs) were exercised and cash-settled for $11 million (2021 - $26 million) based on a weighted average share price on the dates of exercises of $22.01 (2021 - $33.24). During the year ended December 31, 2022, RSUs granted were equity-settled awards and generally vest in four equal annual instalments. PSUs granted vest in three years and are subject to TELUS International revenue and earnings per share performance growth targets. These RSUs and PSUs are eligible for dividend reinvestment units, if declared and paid by TELUS International, as such the fair value was determined to be equal to the market price of a subordinate voting share of TELUS International on the date of grant. As at December 31, 2022, the outstanding restric ted share units were comprised of 1,218,796 RSUs, 387,025 PSUs, and nil Phantom RSUs and PSUs (2021 - 1,083,542 RSUs, 192,064 PSUs, 285,386 Phantom RSUs and 289,815 Phantom PSUs). The share-based compensation liability as at December 31, 2022 for liability-accounted awards was $nil (2021 - $22 million). Phantom TELUS Corporation restricted share units (Phantom TELUS Corporation RSU) Each Phantom TELUS Corporation RSU is nominally equal in value to one TELUS Corporation common share and is nominally entitled to the dividends that would arise thereon if it were an issued and outstanding TELUS Corporation common share. The notional dividends are recorded as additional issuances of restricted share units during the vesting period of the restricted share unit. Due to the notional dividend mechanism, the grant-date fair value of restricted share units equals the fair market value of the corresponding TELUS Corporation common shares at the grant date. The restricted share units generally become payable when vesting is completed and typically vest over a period of 30 months (the requisite service period). These restricted share units generally have a variable payout (0%-150%) depending upon our financial performance and non-market quality-of-service performance conditions. The grant-date fair value of our restricted share units affected by the financial performance and non-market quality-of-service performance conditions equals the fair market value of the corresponding TELUS Corporation common shares at the grant date. The Phantom TELUS Corporation RSUs are historic grants made to certain employees, and no new awards are expected to be made. 2022 2021 2020 Phantom TELUS Phantom TELUS Phantom TELUS Years Ended December 31 Canadian $ denominated Non-vested Vested Weighted Non-vested Vested Weighted Non-vested Vested Weighted Outstanding, beginning of year 78,011 — $ 24.20 156,749 — $ 24.17 253,622 — $ 23.78 Granted — — — 24,757 — 27.58 13,217 — 24.97 Vested (59,549) 59,549 24.13 (85,154) 85,154 23.96 (113,737) 113,737 25.49 Exercised (1) — (59,549) 24.13 — (86,745) 25.22 — (113,737) 25.49 Dividends 1,568 — 30.85 5,023 1,591 27.43 10,156 — 15.42 Forfeited (20,030) — 24.92 (23,364) — 24.72 (6,509) — 23.59 Outstanding, end of year — — $ — 78,011 — $ 24.20 156,749 — $ 24.17 _________________________________________________ (1) During the year ended December 31, 2022, Phantom TELUS Corporation RSUs exercised were cash-settled for CAD$2 million (2021 - CAD$2 million), reflecting the share price on the date of exercise of CAD$28.67 (2021 - CAD$27.58) . (b) Share option awards We have equity-accounted share option awards (Share Options), and liability-accounted share option awards (Phantom Share Options). Share Options grant the right to the employee recipient to purchase and receive a subordinate voting share of TELUS International for a pre-determined exercise price. Phantom Share Options grant the right to the employee recipient to receive cash equal to the intrinsic value of the share option award, determined as the difference between the market price of a subordinate voting share of TELUS International and the exercise price. Share option awards are generally exercisable for a period of ten years from the time of grant. Beginning January 1, 2021, share option awards granted were equity-accounted. During the year ended December 31, 2022, Share Options granted generally vested annually over a four-year period, in four equal instalments (graded-vesting method), and expire in ten-years. Share Options granted prior to December 31, 2020 generally vested after the requisite service period of three-years was completed (cliff-vesting method), however were not exercisable prior to the completion of an initial public offering, which occurred on February 3, 2021. All Share Options are valued using the Black-Scholes valuation model on the date of grant, and is not revalued subsequently unless a modification has occurred. Phantom Share Options generally vest over 30 months and are liability-accounted, which requires a periodic mark-to-market adjustment to revalue the liability to reflect the fair value of the awards. Fair value of the awards is determined using the Black-Scholes valuation model, adjusted for the number of awards that have vested to date and the expected variable payout (0%-100%) depending upon our financial performance and non-market quality-of-service performance conditions. No Phantom Share Options were granted during the year ended December 31, 2022. In using the Black-Scholes valuation model, the following inputs are used: risk-free interest rate is based on a Government of Canada yield curve that is current at the time of grant; expected lives of the share option awards are based on management’s best estimate of the time to option expiration based on historical trends and other factors; expected volatility considers the historical volatility in the observable prices of our own and our comparable peers; dividend yield is the expected dividend yield for a subordinate voting share of TELUS International.

Our operations are complex and the related income tax interpretations, regulations, legislation and jurisprudence are continually changing. As a result, there are usually some income tax matters in question. Temporary differences comprising the net deferred income tax asset and the amounts of deferred income taxes recognized in the consolidated statement of income and other comprehensive income and the consolidated statement of changes in owners’ equity are estimated as follows: (millions) Property, plant and equipment Net pension Debt and Provisions Non-capital Leases Net deferred As at January 1, 2021 $ (356) $ 6 $ (1) $ 15 17 2 $ (317) Acquired during the year and other (3) — — — — — (3) Deferred income tax (expense) recovery recognized in: Net income 32 (3) — (9) (2) 1 19 Other comprehensive income — — — (1) — — (1) Foreign currency translation $ 11 $ — $ — $ — $ — $ — 11 Share capital $ — $ — $ 9 $ — $ — $ — 9 Other $ — $ 1 $ — $ (1) $ — $ — — As at December 31, 2021 $ (316) $ 4 $ 8 $ 4 $ 15 $ 3 $ (282) Deferred income tax (expense) recovery recognized in: Net income 32 (3) (2) 9 (5) (1) 30 Other comprehensive income 8 — — (1) — — 7 Foreign currency translation — — — (5) — — (5) As at December 31, 2022 $ (276) $ 1 $ 6 $ 7 $ 10 $ 2 $ (250) Presented on the consolidated statement of financial position as: Deferred income tax asset $ 23 Deferred income tax liability (305) As at December 31, 2021 $ (282) Deferred income tax asset $ 14 Deferred income tax liability (264) As at December 31, 2022 $ (250) Temporary differences arise from the carrying value of the investments in subsidiaries exceeding their tax base, for which no deferred income tax liabilities have been recognized because the parent is able to control the timing of the reversal of the difference and it is probable that it will not reverse in the foreseeable future. In our specific instance, this is relevant to our investments in our non-Canadian subsidiaries. We are not required to recognize such deferred income tax liabilities, as we are in a position to control the timing and manner of the reversal of the temporary differences and it is probable that such differences will not reverse in the foreseeable future. (c) Other As at December 31, 2022, the Company had cumulative tax losses of $53 million for which no deferred tax asset were recognized (2021 - $30 million). Of this amount, $8 million can be carried forward indefinitely, $37 million has a 20-year carryforward period and $8 million has a 5-year carryforward period. During the year ended December 31, 2022, we recognized the benefit of $2 million (2021 - $4 million) of non-capital losses. As at December 31, 2022, the Company had a deferred tax asset of $4 million which is dependent on future earnings of the Company as management considers it probable that taxable profits would be available against which such losses can be used.

Current economic conditions (including forward-looking macroeconomic data), historical information (including credit agency reports, if available), reasons for the accounts being past due and line of business from which the customer accounts receivable arose are all considered when determining whether to make allowances for past-due accounts. The same factors are considered when determining whether to write off amounts charged to the allowance for doubtful accounts against the customer accounts receivable. The doubtful accounts expense is calculated on a specific-identification basis for customer accounts receivable over a specific balance threshold and on a statistically derived allowance basis for the remainder. No customer accounts receivable balances are written off directly to bad debt expense.

Financial instruments and management of financial risks	Financial instruments and management of financial risks (a) Risks—overview Our financial instruments, and the nature of certain risks to which they may be subject, are as set out in the following table. Risks Market risks Financial instrument Accounting classification Credit Liquidity Currency Interest Other price Measured at amortized cost Accounts receivable AC (1) X X Due from/to affiliated companies AC (1) X X Accounts payable and accrued liabilities AC (1) X X Long-term debt AC (1) X X Measured at fair value Cash and cash equivalents FVTPL (2) X X X Foreign exchange derivatives (3) FVTPL/FVOCI (2) X X X _________________________________________________ (1) For accounting recognition and measurement purposes, classified as amortized cost (AC). (2) For accounting recognition and measurement purposes, classified as fair value through net income (FVTPL). Unrealized changes in the fair values of financial instruments are included in net income unless the instrument is part of a cash flow hedging relationship. The effective portion of unrealized changes in the fair values of financial instruments held for hedging are included in other comprehensive income (FVOCI). (3) Use of derivative financial instruments is subject to a policy which requires that no derivative transaction is to be entered into for the purpose of establishing a speculative or leveraged position (the corollary being that all derivative transactions are to be entered into for risk management purposes only) and sets criteria for the credit worthiness of the transaction counterparties. (b) Credit risk Excluding credit risk, if any, arising from interest rate swaps and currency swaps settled on a gross basis, the best representation of our maximum exposure (excluding income tax effects) to credit risk, which is a worst-case scenario and does not reflect results we expect, is as set out in the following table: As at December 31 (millions) 2022 2021 Cash and cash equivalents $ 125 $ 115 Accounts receivable 428 414 Due from affiliated companies 81 53 Derivative assets 32 3 $ 666 $ 585 Cash and cash equivalents Credit risk associated with cash and cash equivalents is managed by ensuring that these financial assets are placed with: governments; major financial institutions that have been accorded strong investment grade ratings by a primary rating agency; and/or other creditworthy counterparties. An ongoing review is performed to evaluate changes in the status of counterparties. Accounts receivable Credit risk associated with accounts receivable is managed through a program of credit evaluations of customers and limiting the amount of credit extended when deemed necessary. See Note 11—Accounts receivable for additional details of our accounts receivable balances. Derivative assets (and derivative liabilities) Counterparties to our foreign exchange derivatives are major financial institutions that have been accorded investment grade ratings by a primary credit rating agency. The total dollar amount of credit exposure under contracts with any one financial institution is limited and counterparties’ credit ratings are monitored. We do not give or receive collateral on swap agreements and hedging items due to our credit rating and those of our counterparties. While we are exposed to the risk of potential credit losses due to the possible non-performance of our counterparties, we consider this risk remote. Our derivative liabilities do not have credit risk-related contingent features. (c) Liquidity risk We manage liquidity risk by: • maintaining a syndicated bank credit facility ( Note 15(b)—Long-term debt—Credit facility ); • continuously monitoring forecast and actual cash flows; and • managing maturity profiles of financial assets and financial liabilities. Our debt maturities in future years are as disclosed in Note 15(d)—Long-term debt—Long-term debt maturities . We closely match the contractual maturities of our derivative financial liabilities with those of the risk exposures they are being used to manage. The expected maturities of our undiscounted financial liabilities do not differ significantly from the contractual maturities, other than as noted below. The contractual maturities of our undiscounted financial liabilities as at December 31, 2022, including interest thereon (where applicable), are as set out in the following tables: Non-derivative Derivative Composite long-term debt Currency swap Year (millions) Non- Due to Long-term debt, excluding leases (1) (Note 15) Leases (Receive) Pay Total 2023 $ 321 $ 111 $ 73 $ 68 $ (145) $ 126 $ 554 2024 40 — 78 58 (39) 23 160 2025 7 — 76 47 (321) 314 123 2026 7 — 74 40 — — 121 2027 6 — 72 24 — — 102 Thereafter 18 — 599 47 — — 664 Total $ 399 $ 111 $ 972 $ 284 $ (505) $ 463 $ 1,724 _________________________________________________ (1) Future cash outflows in respect of associated interest and carrying costs for amounts drawn under our credit facilities (if any) have been calculated based upon the rates in effect at December 31, 2022. (d) Currency risk Our primary operating currency is the United States dollar. The European euro, Philippine peso and the Canadian dollar are the foreign currencies to which we currently have the largest exposure. Our foreign exchange risk management includes the use of foreign currency forward contracts to fix the exchange rates on short-term Philippine peso and Indian rupee-denominated transactions and commitments, as well as swaps which are used to manage the currency risk associated with European euro denominated inflows being used against United States dollar denominated debt. (e) Interest rate risk Changes in market interest rates will cause fluctuations in the fair value or future cash flows of short-term investments, short-term obligations and long-term debt. Our cash equivalents generally have short maturities and fixed interest rates and as a result, their fair value will fluctuate with changes in market interest rates; absent monetization prior to maturity, the related future cash flows will not change due to changes in market interest rates. As short-term obligations arising from bilateral bank facilities, which typically have variable interest rates, are rarely outstanding for periods that exceed one calendar week, interest rate risk on these facilities are not significant. Amounts drawn on our long-term cr edit facility wil l be affected by changes in market interest rates in a manner similar to debts with short maturities in that the fair value is not materially affected by changes in market interest rates, but the associated cash flows representing interest payments are. We manage our exposure to changes in market interest rates with the use of interest rate swaps to fix the interest rates on the variable rate portion of our credit facility. (f) Market risk Net income and other comprehensive income for the years ended December 31, 2022, 2021 and 2020, could have varied if the United States dollar: Canadian dollar exchange rate, United States dollar: Philippine peso exchange rate, United States dollar: European euro exchange rate, market interest rates, and the TELUS Corporation and TELUS International (Cda) Inc. common share prices varied by reasonably possible amounts from their actual statement of financial position date amounts. The following sensitivity analysis of our exposure to currency, interest rate and other price risks at the reporting date has been determined based upon (i) a hypothetical change in foreign exchange rates taking place at the relevant statement of financial position date for the Canadian dollar, European euro and Philippine peso denominated balances; (ii) the hypothetical change in interest rates taking place at the beginning of the relevant fiscal year and being held constant through to the statement of financial position date; and (iii) the hypothetical change in the price of a subordinate voting share of TELUS International at the relevant statement of financial position date, and the corresponding impact to share-based compensation on that reporting date. Net income Other Comprehensive Years Ended December 31 (increase (decrease) in millions) 2022 2021 2020 2022 2021 2020 2022 2021 2020 Reasonably possible changes in market risks (1) 10% change in US$: CAD$ exchange rate US$ appreciates $ 8 $ 14 $ 9 $ — $ — $ — $ 8 $ 14 $ 9 US$ depreciates $ (8) $ (14) $ (9) $ — $ — $ — $ (8) $ (14) $ (9) 10% change in US$: Euro exchange rate US$ appreciates $ 14 $ 11 $ 4 $ (44) $ (36) $ (38) $ (30) $ (25) $ (34) US$ depreciates $ (14) $ (11) $ (4) $ 44 $ 36 $ 38 $ 30 $ 25 $ 34 10% change in US$: Peso exchange rate US$ appreciates $ (2) $ (1) $ (1) $ — $ — $ — $ (2) $ (1) $ (1) US$ depreciates $ 2 $ 1 $ 1 $ — $ — $ — $ 2 $ 1 $ 1 25 basis point change in market interest rate Rate increases $ (1) $ (2) $ (4) $ — $ — $ 1 $ (1) $ (2) $ (3) Rate decreases $ 1 $ 2 $ 4 $ — $ — $ (1) $ 1 $ 2 $ 3 25% (2) change in subordinate voting share price (3) Price increases $ — $ (5) $ (4) $ — $ — $ — $ — $ (5) $ (4) Price decreases $ — $ 5 $ 4 $ — $ — $ — $ — $ 5 $ 4 _________________________________________________ (1) These sensitivities are hypothetical and should be used with caution. Changes in net income and/or other comprehensive income generally cannot be extrapolated because the relationship of the change in assumption to the change in net income and/or other comprehensive income may not be linear. In this table, the effect of a variation in a particular assumption on the amount of net income and/or other comprehensive income is calculated without changing any other factors; in reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities. The sensitivity analysis assumes that we would realize the changes in exchange rates; in reality, the competitive marketplace in which we operate would have an effect on this assumption. No consideration has been made for a difference in the notional number of common shares associated with share-based compensation awards made during the reporting period that may have arisen due to a difference in the common share price. (2) To facilitate ongoing comparison of sensitivities, a constant variance of approximate magnitude has been used. (3) The hypothetical effects of changes in the price of our subordinate voting shares and those of TELUS Corporation are limited to those which arise from our liability-accounted share-based compensation awards. (g) Fair values General The carrying values of cash and cash equivalents, accounts receivable, and accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of these financial instruments. The fair values of the derivative financial instruments we use to manage our exposure to currency risks are estimated based upon quoted market prices in active markets for the same or similar financial instruments or on the current rates offered to us for financial instruments of the same maturity, as well as discounted future cash flows determined using current rates for similar financial instruments subject to similar risks and maturities (such fair value estimates being largely based on the European euro: US$ and Philippine peso: US$ forward exchange rates as at the statement of financial position dates). Derivative The derivative financial instruments that we measure at fair value on a recurring basis subsequent to initial recognition are as set out in the following table; all such items use significant other observable inputs (Level 2) for measuring fair value at the reporting date. 2022 2021 As at December 31 (millions) Designation Maximum Notional Fair Price or Maximum Notional Fair Price or Current assets (1) Derivatives used to manage Currency risks arising from Indian rupee denominated purchases HFT (2) — $ — $ — — 2022 $ 10 $ — USD:1.00 INR:76.21 Currency risks arising from Philippine peso denominated purchases HFT (2) 2023 $ 53 $ — USD:1.00 PHP:56.90 — $ — $ — — Currency risks arising from Euro business acquisition HFH (3) 2023 $ 21 $ 19 USD:1.00EUR:0.86 2022 $ 21 $ 3 USD:1.00EUR:0.86 Non-current assets (1) Derivatives used to manage Currency risks arising from Euro business acquisition HFH (3) 2025 $ 341 $ 13 USD:1.00EUR:0.86 — $ — $ — — Current liabilities (1) Derivatives used to manage Currency risks arising from Philippine peso denominated purchases HFH (3) 2023 $ 50 $ 1 USD:1.00PHP:53.55 2022 $ 92 $ 3 USD:1.00 PHP:50.10 Currency risks arising from Indian rupee denominated purchases HFT (2) — $ — $ — — 2022 $ 2 $ — USD:1.00 INR:74.99 Interest rate risk associated with non-fixed rate credit facility amounts drawn HFH (3) — $ — $ — — 2022 $ 95 $ 2 2.64% Non-current liabilities (1) Derivatives used to manage Currency risks arising from Euro business acquisition HFH (3) — $ — $ — — 2025 $ 362 $ 17 USD:1.00EUR:0.86 ______________________________________ (1) Notional amounts of derivative financial assets and liabilities are not set off. (2) Foreign currency hedges are designated as held for trading (HFT) upon initial recognition; hedge accounting is not applied. (3) Designated as held for hedging (HFH) upon initial recognition (cash flow hedging item); hedge accounting is applied. Unless otherwise noted, hedge ratio is 1:1 and is established by assessing the degree of matching between the notional amounts of hedging items and the notional amounts of the associated hedged items. Non-derivative The fair value amounts for cash and cash equivalents approximate carrying amounts due to the short-term maturities of these instruments. Our long-term debt, which is measured at amortized cost, approximates the fair value thereof due to the short-term nature of the applicable rates of interest charged. (h) Recognition of derivative gains and losses The following table sets out the gains and losses, excluding income tax effects, arising from derivative instruments that are classified as cash flow hedging items and their location within the Consolidated statements of income and other comprehensive income. Credit risk associated with such derivative instruments, as discussed further in (b) , would be the primary source of hedge ineffectiveness.

(b) Impairment testing of goodwill Goodwill is tested for impairment annually or more frequently if events or circumstances indicate that the asset may be impaired. We perform our goodwill impairment test annually as at October 1, in accordance with our policy in Note 1(g)—Summary of significant accounting policies—Depreciation, amortization and impairment . Goodwill impairment is tested at the lowest cash-generating unit (CGU) that goodwill is monitored. On this basis, we have determined that each geographic area in which we operate is insufficiently distinct and is not considered to be an individual cash generating unit, and our combined operations are considered to represent a single CGU. In assessing goodwill for impairment, we compare the carrying value of our CGU to its recoverable amount, determined using a value-in-use method. There is a material degree of uncertainty with respect to the estimate of the recoverable amount, given the necessity of making key economic assumptions about the future. As such, we validate our recoverable amount calculations using market-comparable measures and perform an analytical review of industry facts and facts that are specific to us. For the years ended December 31, 2022, 2021 and 2020, no goodwill impairment was recorded. Methodology and key assumptions The value-in-use calculation uses discounted cash flow projections, including the following key assumptions: future cash flows and growth projections; associated economic risk assumptions and estimates of the likelihood of achieving key operating metrics and drivers; estimates of future capital expenditures; and the future weighted average cost of capital. We considered a range of reasonably possible amounts to use for key assumptions and selected amounts that best represent management’s estimates of current and future market conditions. The key assumptions for cash flow projections were based upon our approved financial forecasts, which span a period of five years and are discounted at a po st-tax notional rate of 9.5% (2021 - 9.0%; 2020 - 9.7%). For impairment testing valuations, cash flows subsequent to the five-year projection period are extrapolated using a perpetual growth rate of 3.0% (2021 - 3.0%; 2020 - 3.5%); these growth rates do not exceed the long-term average growth rates observed in the markets in whi ch we operate. We believe that any reasonably possible change in the key assumptions on which the calculation of the recoverable amounts would not cause the CGU’s carrying value to exceed its recoverable amount. If the future were to adversely differ from management’s best estimates for the key assumptions and associated cash flows were to be materially adversely affected, we could potentially experience future material impairment charges in respect of our goodwill. (c) Business acquisition subsequent to reporting period - WillowTree On October 27, 2022, we announced a definitive agreement to acquire WillowTree, a full-service digital product provider focused on end user experiences, such as native mobile applications and unified web interfaces. On January 3, 2023, subsequent to the satisfaction of the closing conditions, we completed our acquisition of WillowTree. Under the agreement, TELUS International acquired WillowTree for total purchase consideration of approximately $1.1 billion, net of assumed debt, and comprised of cash, $125 million of our subordinate voting shares, and provisions for written put options for the portion retained by certain eligible management team members that will be settled subject to certain performance-based criteria. WillowTree management team members retained approximately 15% of total WillowTree equity, and we granted written put options to such management team members which will become exercisable in tranches over a three-year period starting in 2026. These written put options may be settled in cash or, at our discretion, in a combination of cash and up to 70% in subordinate voting shares, and this will be recorded as a provision, measured at fair value, in our condensed interim consolidated financial statements in the first quarter of 2023. Concurrent with this acquisition, WillowTree management team members provided us with purchase call options, which substantial ly mirror the written put options. The acquisition brings key talent and diversity to our segment’s portfolio of next generation solutions, and further augments its digital consulting and client-centric software development capabilities. The primary factor that gives rise to the recognition of goodwill on this acquisition was the earnings capacity of the acquired business in excess of the net tangible and intangible assets acquired (such excess arising from the low level of tangible assets relative to the earnings capacity of the business). A portion of the amounts assigned to goodwill may be deductible for income tax purposes. Given the proximity of the acquisition to the reporting date, the Company is still in the process of finalizing the determination of the fair values of the acquired assets and liabilities, and the provisions for written put options. Specifically, we are in the process of obtaining additional information in order to assess the fair values of intangible assets and deferred income taxes and the resulting impact to goodwill as at the date of the acquisition. In connection with the WillowTree acquisition, on December 20, 2022, we amended and expanded our existing credit facility to an aggregate $2 billion credit facility, consisting of an $800 million revolving credit facility and $1.2 billion in t erm loans payable in five years (see Note 15(b)—Long-term debt—Credit facility

(2) Of the amounts available at December 31, 2022, $525 million of the revolving components and $600 million of the term loan components had a condition precedent of consummating the WillowTree acquisition, which occurred on January 3, 2023 (see Note 14(c)—Intangible assets and goodwill—Business acquisition subsequent to reporting period - WillowTree). On December 20, 2022, we amended and expanded our total credit facility to $2 billion, comprised of an $800 million revolving component and an amortizing $1,200 million term loan component, maturing on January 3, 2028. Subsequent to year end, on January 3, 2023, the $600 million available balance under the term loan component was drawn, and the revolving component of our credit facility was increased to $505 million to fund our acquisition of WillowTree (see Note 14(c)—Intangible assets and goodwill—Business acquisition subsequent to reporting period - WillowTree ). The credit facility is secured by our assets with a syndicate of financial institutions, which included TELUS Corporation as a lender under the credit facility. As at December 31, 2022, the revolving and term loan components had an effective interest rate of 6.67% The amended credit facility bears interest at prime rate, U.S. dollar base rate, a bankers’ acceptance rate or Term Secured Overnight Financing Rate (SOFR) (all such terms as used or defined in the amended credit facility), plus applicable margins. The amended credit facility contains customary representations, warranties and covenants, including two financial quarter-end ratio tests. Net Debt to EBITDA ratio must not exceed 4.25:1.00 for each quarter in fiscal 2023, 3.75:1.00 for each quarter in fiscal 2024 and 3.25:1.00 subsequently. The EBITDA to Debt Service (interest and scheduled principal repayment) ratio must not be less than 1.50:1.00, all as defined in the credit facility. If an acquisition with an aggregate cash consideration in excess of $250 million occurs in any twelve-month period, the maximum permitted Net Debt to EBITDA ratio per credit agreement may be increased by 0.50:1.00 and shall return to the then applicable Net Debt to EBITDA ratio after eight fiscal quarters. The term loan component of our credit facility is subject to an amortization schedule requiring that 1.25% of the original principal advanced be repaid each quarter of the term of the agreement, with the balance due at maturity of As at December 31, 2022 and 2021, we were in compliance with all financial covenants, financial ratios and all of the terms and conditions of our long-term debt agreements.

Disclosure of classes of share capital [abstract]
Share capital	Share capital In connection with our IPO on February 3, 2021, TELUS Corporation, our controlling shareholder, exchanged its outstanding Class A, Class C and Class D shares for Class B shares. Each other holder of Class C and Class D shares exchanged their shares for Class E shares. Our Class B shares, which were then only held by TELUS Corporation and Baring Private Equity Asia, a non-controlling shareholder, were redesignated as multiple voting shares and our Class E shares were redesignated as subordinate voting shares. In 2022, BPEA EQT (BPEA) was formed as a result of the combination of Baring Private Equity Asia and EQT Asia. The rights of the holders of our multiple voting shares and subordinate voting shares are substantially identical, except subordinate voting shares have one vote per share and multiple voting shares have 10 votes per share. Concurrent with the redesignations, we eliminated all of our previously outstanding series of Class A, Class C and Class D shares and our authorized Class A and Class B preferred shares. Subsequent to the IPO, our equity shares were comprised only of subordinate voting shares and multiple voting shares. Subsequent to the share redesignations, we effected a 4.5-for-1 split of each of our outstanding multiple voting shares and subordinate voting shares. In all instances, unless otherwise indicated, the number of equity shares authorized, the number of equity shares outstanding, the number of equity shares reserved, per share amounts and share-based compensation information in these consolidated financial statements have been restated to reflect the impact of the 4.5-for-1 split. In connection with our IPO, we issued 21.0 million subordinate voting shares at $25.00 per share, for gross proceeds of $525 million and net proceeds of $500 million (net of share issuance costs of $34 million, which included underwriting fees and offering expenses, offset by deferred taxes of $9 million). TELUS Corporation and BPEA also sold 21.6 million subordinated voting shares in the IPO at the same price, which were issued following the conversion by them of an aggregate 21.6 million multiple voting shares. In the third quarter of 2021, we completed a secondary offering of 16.6 million subordinate voting shares at $34.00 per share on behalf of certain non-controlling shareholders of TELUS International, including BPEA. In connection with this secondary offering, 13.6 million multiple voting shares of BPEA were converted to subordinate voting shares and sold. Neither TELUS International nor TELUS Corporation sold any subordinate voting shares in this secondary offering and did not receive any proceeds from the sale of the subordinate voting shares by the selling shareholders.

Disclosure of contingent liabilities [abstract]
Contingent liabilities	Contingent liabilities (a) Indemnification obligations In the normal course of operations, we provide indemnification in conjunction with certain transactions. The terms of these indemnification obligations range in duration. These indemnifications would require us to compensate the indemnified parties for costs incurred as a result of failure to comply with contractual obligations or litigation claims or statutory sanctions or damages that may be suffered by an indemnified party. In some cases, there is no maximum limit on these indemnification obligations. The overall maximum amount of an indemnification obligation will depend on future events and conditions and therefore cannot be reasonably estimated. Where appropriate, an indemnification obligation is recorded as a liability. Other than obligations recorded as liabilities at the time of such transactions, historically we have not made significant payments under these indemnifications. As at December 31, 2022 and 2021, we had no liability recorded in respect of indemnification obligations. (b) Claims and lawsuits We are party to various legal proceedings and claims that arise in the ordinary course of business. The ultimate outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's estimates of loss, or if any outcome becomes more likely than not and estimable, our results of operations and financial condition could be adversely affected.

Employee future benefits
Employee future benefits	Employee future benefits Defined contribution pension plans We have a number of defined contribution retirement plans providing pension and other post-employment benefits to our employees. Employees in most of our foreign subsidiaries are covered by government mandated, defined contribution plans. Employees generally become eligible to participate in these plans after six months of employment and the Company may make discretionary contributions under the plans. We offer defined contribution pension plans in certain regions, which are contributory and generally voluntary, and these are the pension plans that we sponsor and are available to our employees. Generally, employees can make contributions up to a maximum amount, and we matched up to 100% of the contributions based on plan limits. See Note 5—Salaries and benefits for defined contribution pension expense included in Salaries & benefits in the consolidated statements of income and comprehensive income. Defined benefit pension plans We have a small number of Canadian employees who participate in a TELUS Corporation defined benefit plan, and the associated cost related to TELUS International employees is charged to us by TELUS Corporation. For the years ended December 31, 2022, 2021 and 2020, we recognized defined benefit pension expense of $2 million, $1 million and $nil included in Salaries & benefits in the consolidated statements of income and comprehensive income. In addition, we have non-contributory supplementary retirement benefit plans, which have the effect of maintaining the earned pension benefit once the allowable maximums in the registered plans are attained. As is common with non-registered plans of this nature, these plans are typically funded only as benefits are paid. For the years ended December 31, 2022, 2021 and 2020, we recognized defined benefit pension expense included in Salaries & benefits of $nil, $1 million and $1 million, respectively. As at December 31, 2022, 2021 and 2020, our recognized pension obligation was $9 million, $11 million and $15 million, respectively, included in Other long-term liabilities in the consolidated statement of financial position.

During the year ended December 31, 2022, TELUS Corporation incurred $2 million (December 31, 2021 - $nil) for these individuals, which are excluded from the table above. In the consolidated statement of financial position, amounts due from affiliates and amounts due to affiliates are generally due 30 days from billing and are cash-settled on a gross basis. In January 2021, we renewed our master service agreement with TELUS Corporation, which provides for a term of 10 years beginning in January 2021 and a minimum annual spend of $200 million, subject to adjustment in accordance with its terms. Other transactions On January 29, 2020, in connection with the acquisition of CCC, we issued 14.7 million Class A common shares and 0.2 million Class C common shares to TELUS Corporation for $126 million. The proceeds from these share issuances were used to finance the acquisition. On April 1, 2020, we issued 3.5 million Class C common shares for proceeds of $49 million to TELUS Corporation as consideration for the acquisition of MITS from TELUS Corporation, a common control transaction . We also issued 5.4 million Class A common shares to TELUS Corporation for proceeds of $75 million to finance the buy-out of the non-controlling interest in Xavient Digital in April 2020. On December 29, 2020, in connection with the acquisition of Lionbridge AI , we issued 7.6 million Class A common shares to TELUS Corporation for $150 million. The proceeds from these share issuances were used to finance the acquisition. Immediately prior to the Company’s IPO on February 3, 2021, all Class A, Class C, and Class D common shares held by TELUS Corporation were exchanged for Class B common shares, and these Class B common shares were then redesignated as multiple voting shares. Subsequent to such redesignations, we effected a 4.5-for-1 split of each of our outstanding multiple voting shares. On a post-split basis, TELUS Corporation held 153.0 million multiple voting shares of TELUS International. On February 3, 2021, and in connection with the Company’s IPO, TELUS Corporation converted 6.5 million of our multiple voting shares to subordinate voting shares that were sold to new investors in the initial public offering. In the fourth quarter of 2022, we acquired certain call centre operations of TELUS Corporation for cash consideration of $1 million (net of cash assumed), in exchange for $2 million of net identifiable assets and $9 million of goodwill. This acquisition was accounted for as a common control business acquisition using the predecessor accounting method. The amount of net assets and goodwill acquired in excess of the fair value of consideration paid was recorded to contributed surplus in the consolidated statements of changes in owners’ equity. (b) Transactions with BPEA EQT General BPEA exercises significant influence on TELUS International. Recurring transactions As at, and during the years ended December 31, 2022 and 2021, there were no balances due to or due from, or recurring transactions with, BPEA.

The proceeds from these share issuances were used to finance the acquisition. Immediately prior to the Company’s IPO on February 3, 2021, all Class B common shares held by BPEA were redesignated as multiple voting shares. Subsequent to such redesignations, we effected a 4.5-for-1 split of each of our outstanding multiple voting shares. On a post-split basis, BPEA held 82.1 million multiple voting shares of TELUS International. In connection with the Company’s IPO, BPEA converted 15.1 million of our multiple voting shares to subordinate voting shares that were sold to new investors in the initial public offering.

Disclosure of operating segments [abstract]
Segment reporting	Segment reporting Operating segments are components of an entity that engage in business activities from which they earn revenues and incur expenses (including revenues and expenses related to transactions with the other entities within the group). We assess our operating segments based on information regularly provided to and reviewed by the Chief Operating Decision Maker (CODM), which we have identified as our Chief Executive Officer. This information is used to make resource allocation decisions and to assess financial performance. Our CODM reviews financial information prepared on a consolidated basis for the purposes of making resource allocation decisions and assessing the performance of the overall organization. Based on an evaluation of all facts and circumstances, the Company has determined that it functions as a single operating and reporting segment. We attribute revenues from external customers to individual countries based on the location of our delivery centres or where the services were provided from.

Summary of significant accoun_2

Summary of significant accounting policies
Basis of presentation	Basis of presentation Our consolidated financial statements are expressed in United States dollars. The generally accepted accounting principles that we use are International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS-IASB). Generally accepted accounting principles require that we disclose the accounting policies we have selected in those instances where we have been obligated to choose from among various generally accepted accounting principle-compliant accounting policies. In certain other instances, including where no selection among policies is allowed, we are also required to disclose how we have applied certain accounting policies. In our assessment, all of our required accounting policy disclosures are not equally significant for us, as set out in the accompanying table; their relative significance to us will evolve over time as we do.
Consolidation	Consolidation As at December 31, 2022, o ur consolidated financial statements include our accounts and the accounts of all of our subsidiaries. Our principal subsidiaries are: TELUS International (U.S.) Corp.; Xavient Digital LLC; CallPoint New Europe EAD; TELUS International Services Limited; TELUS International Philippines Inc.; Voxpro Limited; TELUS International Germany GmbH; and TELUS International AI Inc. Our financing arrangements and those of our subsidiaries do not impose restrictions on inter-corporate dividends, but external dividends are restricted based upon total net debt to earnings before interest, income taxes, depreciation and amortization (EBITDA) ratios, all as defined by our financing arrangements. On a continuing basis, we review our corporate organization and effect changes as appropriate so as to enhance the value of TELUS International. This process can, and does, affect which of our subsidiaries are considered principal subsidiaries at any particular point in time.
Use of estimates and judgments	Use of estimates and judgmentsThe preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates, assumptions and judgments that affect: the reported amounts of assets and liabilities at the date of the financial statements; the disclosure of contingent assets and liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates Examples of the estimates and assumptions that we make and their relative significance and degree of difficulty are as follows: Judgments Examples of our use of judgment, apart from those involving estimation, include the following: • Assessments about whether line items are sufficiently material to warrant separate presentation in the primary financial statements and, if not, whether they are sufficiently material to warrant separate presentation in the financial statement notes. In the normal course, we make changes to our assessments regarding presentation materiality so that they reflect current economic conditions. Due consideration is given to the view that it is reasonable to expect differing opinions of what is, and is not, material. • In respect of revenue-generating transactions, generally we must make judgments that affect the timing of the recognition of revenue as it relates to assessing when we have satisfied our performance obligations to our customers, either at a point in time or over a period of time. • The preparation of our financial statements in accordance with generally accepted accounting principles requires management to make judgments that affect the financial statement disclosure of information regularly reviewed by our chief operating decision maker used to make resource allocation decisions and to assess performance, as further discussed in Note 22—Segment Reporting . A significant judgment we make is that our cash flows are sufficiently indistinguishable given our global operating model, resulting in a single operating and reporting segment. • Determination of the functional currency of each subsidiary involves significant judgment. The determination of functional currency affects the carrying value of non-current assets included in the statement of financial position and, as a consequence, the amortization of those assets, as well as the exchange gains and losses recorded in the consolidated statement of comprehensive income and the consolidated statement of equity. • The decision to depreciate and amortize any property, plant, equipment and intangible assets that are subject to amortization on a straight-line basis, as we believe that this method reflects the consumption of resources related to the economic lifespan of those assets better than an accelerated method and is more representative of the economic substance of the underlying use of those assets. • In connection with the annual impairment testing of goodwill, there are instances where we must exercise judgment in the determination of our cash generating unit. A significant judgment that we make is that each geographic area in which we operate is insufficiently distinct, making it impractical to objectively distinguish the cash flows of each region. As such, each region is not an individual cash generating unit. • In respect of claims and lawsuits, as discussed further in Note 17(b)—Contingent liabilities—Claims and lawsuits , the determination of whether an item is a contingent liability or whether an outflow of resources is probable and thus needs to be accounted for as a provision.
Financial instruments - recognition and measurement	Financial instruments—recognition and measurement In respect of the recognition and measurement of financial instruments, we have adopted the following policies: • Derivatives that are part of an established and documented cash flow hedging relationship are accounted for as held for hedging. We believe that classification as held for hedging results in a better matching of the change in the fair value of the derivative financial instrument with the risk exposure being hedged. • Derivatives that are not part of a documented cash flow hedging relationship are accounted for as held for trading and thus are measured at fair value through net income. • Transaction costs, other than in respect of items held for trading, are added to the initial fair value of the acquired financial asset or financial liability. We have selected this method as we believe that it results in a better matching of the transaction costs with the periods in which we benefit from the transaction costs.
Hedge accounting	Hedge accounting Hedge accounting The purpose of hedge accounting, in respect of our designated hedging relationships, is to ensure that counterbalancing gains and losses are recognized in the same periods. We have chosen to apply hedge accounting as we believe that it is more representative of the economic substance of the underlying transactions. In order to apply hedge accounting, a high correlation (which indicates effectiveness) is required in the offsetting changes in the risk-associated values of the financial instruments (the hedging items) used to establish the designated hedging relationships and all, or a part, of the asset, liability or transaction having an identified risk exposure that we have taken steps to modify (the hedged items). We assess the anticipated effectiveness of designated hedging relationships at inception and their actual effectiveness for each reporting period thereafter. We consider a designated hedging relationship to be effective if the following critical terms match between the hedging item and the hedged item: the notional amount of the hedging item and the principal amount of the hedged item; maturity dates; payment dates; and interest rate index (if, and as, applicable). Any ineffectiveness, such as would result from a difference between the notional amount of the hedging item and the principal amount of the hedged item, or from a previously effective designated hedging relationship becoming ineffective, is reflected in the consolidated statements of income and other comprehensive income as Interest expense if in respect of long-term debt, or as Goods and services purchased if in respect of future purchase commitments. Hedging assets and liabilities In the application of hedge accounting, an amount (the hedge value) is recorded in the consolidated statement of financial position in respect of the fair value of the hedging items. The net difference, if any, between the amounts recognized in the determination of net income and the amounts necessary to reflect the fair value of the designated cash flow hedging items recorded in the consolidated statement of financial position is recognized as a component of Other comprehensive income. In the application of hedge accounting to the finance costs arising from interest paid on our long-term debt, the amount recognized in the determination of net income is the amount that counterbalances the difference between interest calculated at a variable interest rate, and the fixed interest rate as per our credit facility.
Revenue recognition	Revenue recognition General Our solutions involve delivery of multiple services and products that occur at different points in time and/or over different periods of time. These arrangements may contain multiple performance obligations and the transaction price is measured and allocated among the performance obligations based upon their relative stand-alone selling price. Our relevant revenue recognition policies are then applied to the performance obligations. Multiple contracts with a single customer are normally accounted for as separate arrangements. In instances where multiple contracts are entered into with a customer in a short period of time, the contracts are reviewed as a group to ensure that, as with multiple performance obligation arrangements, their relative stand-alone selling prices are appropriate. Our revenues are recorded net of any value-added and/or sales taxes billed to the customer concurrent with a revenue-generating transaction. Discounts and rebates are recorded as a reduction to revenue rather than as an expense. We recognize revenues for each accounting period as services are provided, based on fees earned per-productive hour or per transaction. Fees are invoiced to customers on a regular basis. Advance billings are recorded when a billing occurs prior to provision of the associated services; such advance billings are recognized as revenue in the period in which the services are provided.
Depreciation, amortization and impairment	Depreciation, amortization and impairment Depreciation and amortization Property, plant, and equipment, including right-of-use lease assets, are depreciated on a straight-line basis over their estimated useful lives. Depreciation includes amortization of right-of-use lease assets and amortization of leasehold improvements. Leasehold improvements are normally amortized over the lesser of their expected average service life or the term of the lease. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives, which are reviewed at least annually and adjusted as appropriate. Estimated useful lives for our property, plant and equipment and right-of-use assets subject to depreciation are as follows: Estimated Computer hardware and network assets 2 to 10 years Buildings and leasehold improvements 5 to 20 years Furniture and equipment 3 to 7 years Right-of-use lease assets 3 to 20 years Estimated useful lives for our intangible assets subject to amortization are as follows: Estimated Customer contracts and related customer relationships 4 to 15 years Software 3 to 7 years Brand 3 years Standard operating procedures 5 years Crowdsource assets 8 years Impairment—general Impairment testing compares the carrying values of the assets or cash generating units being tested with their recoverable amounts (the recoverable amount being the greater of an asset’s value-in-use or its fair value less costs to sell). Impairment losses are immediately recognized, to the extent that the carrying value of an asset exceeds its recoverable amount. Should the recoverable amounts for impaired assets subsequently increase, the impairment losses previously recognized (other than in respect of goodwill) may be reversed to the extent that the reversal is not a result of “unwinding the discount” and that the resulting carrying values do not exceed the carrying values that would have been the result if no impairment losses had been previously recognized. Impairment—property, plant and equipment; intangible assets subject to amortization In our assessment of estimated useful lives of assets, we consider such items as the timing of technological obsolescence, competitive pressures and future infrastructure utilization plans. These considerations could indicate that the carrying value of an asset may not be recoverable. If the carrying value of an asset were not considered recoverable, an impairment loss is recorded. Impairment—goodwill We assess the carrying value of goodwill each period for indicators of impairment, and an impairment test is performed when an indicator exists. At a minimum, goodwill is tested annually for impairment on October 1.
Translation of foreign currencies	Translation of foreign currencies Trade transactions completed in foreign currencies are translated into United States dollars at the rates of exchange prevailing at the time of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into United States dollars at the rate of exchange in effect at the statement of financial position date, with any resulting gain or loss recorded to Foreign exchange in the consolidated statement of income and other comprehensive income. We have foreign subsidiaries that do not have the United States dollar as their functional currency. Foreign exchange gains and losses arising from the translation of these foreign subsidiaries’ accounts into United States dollars are reported as a component of other comprehensive income.
Income and other taxes	Income and other taxes We follow the liability method of accounting for income taxes. Under this method, current income taxes are recognized for the estimated income taxes payable for the current year. Deferred income tax assets and liabilities are recognized for temporary differences between the tax and accounting bases of assets and liabilities, and also for the benefit of losses available to be carried forward to future years for tax purposes that are more likely than not to be realized. The amounts recognized in respect of deferred income tax assets and liabilities are based upon the expected timing of the reversal of temporary differences or usage of tax losses and application of the substantively enacted tax rates at the time of reversal or usage. We account for any changes in substantively enacted income tax rates affecting deferred income tax assets and liabilities in full in the period in which the changes are substantively enacted. We account for changes in the estimates of tax balances for prior years as estimate revisions in the period in which the changes in estimates arise; we have selected this approach as its emphasis on the statement of financial position is more consistent with the liability method of accounting for income taxes. Our operations are complex and the related domestic and foreign tax interpretations, regulations, legislation and jurisprudence are continually changing. As a result, there are usually some tax matters in question that result in uncertain tax positions. We recognize the income tax benefit of an uncertain tax position when it is more likely than not that the ultimate determination of the tax treatment of the position will result in that benefit being realized; however, this does not mean that tax authorities cannot challenge these positions. We accrue an amount for interest charges on current tax liabilities that have not been funded, which would include interest and penalties arising from uncertain tax positions. We include such charges in the consolidated statement of income and other comprehensive income as a component of income tax expense.
Share-based compensation	Share-based compensation General Share-based compensation awards issued to certain of our employees include phantom and equity restricted share units, and phantom and equity share options. We recognize a share-based compensation expense in respect of these plans based on the fair value of the awards. Generally, the compensation expense of the award is recognized on a straight-line basis over the vesting of the award subject to continued service with us through the vesting date. A compensation expense is recognized for awards containing performance conditions only to the extent that it is probable that those performance conditions will be met and based on the expected achievement factor. Adjustments are made to reflect expected and actual forfeitures during the vesting period due to failure to satisfy service conditions or performance conditions against the original compensation expense recognized. Restricted share units Restricted share units are accounted for as equity instruments if they will be equity-settled, or liability instruments if they will be cash-settled. For equity-accounted awards, we recognize and measure compensation expense based on the grant date fair value, which is determined to be equal to the market price of one TELUS International subordinate voting share or TELUS Corporation common share. Fair value is not subsequently re-measured unless the conditions on which the award was granted are modified. For liability-accounted awards, we accrue a liability equal to the product of the number of vesting restricted share units multiplied by the market price of one TELUS International subordinate voting share at the end of the reporting period. A mark-to-market adjustment is recorded each period based on changes in the market price of shares. Share option awards Share option awards are accounted for as equity instruments if they will be equity-settled, or liability instruments if they are cash-settled. For equity-accounted awards, we recognize and measure compensation expense based on the grant date fair value, which is determined using the Black-Scholes option pricing model. Fair value is not subsequently re-measured unless the conditions on which the award was granted are modified. Proceeds arising from the exercise of equity-accounted share option awards are recognized as an increase to share capital, as are the recognized grant-date fair values of the exercised share option awards. For liability-accounted awards, we recognize and measure compensation expense based on the fair value of the award at the end of each reporting period, which is determined using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of certain assumptions, some of which are highly subjective, including the expected volatility of the price of our common shares, the expected term of the option and the expected dividend yield of our shares. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our share-based compensation expense could be materially different in future periods.
Employee future benefit plans	Employee future benefit plans The Company records annual amounts relating to its defined benefit plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, compensation increase and turnover rates. When the defined benefit plan’s key assumptions fluctuate relative to their immediately preceding year-end values, such actuarial gains or losses are recognized in other comprehensive income. We participate in defined benefit pension plans that share risks between TELUS Corporation and its subsidiaries as well as unfunded, non-contributory retirement plans of TELUS International and its subsidiaries. TELUS Corporation’s policy is to charge us our participant-based net defined benefit pension cost, as measured in accordance with IAS 19 , Employee Benefits , which are actuarially determined using the accrued benefit method pro-rated on service and management’s best estimates of salary escalation and the retirement ages of employees. In the determination of net income, net interest for each plan, which is the product of the plan’s surplus (deficit) multiplied by the discount rate, is included as a component of Interest expense.
Cash and cash equivalents	Cash and cash equivalentsCash and cash equivalents includes short-term investments in money market funds and other highly liquid, low-risk instruments with maturities of less than three months. Cash and cash equivalents are presented net of outstanding items, including cheques written but not cleared by the related banks as at the statement of financial position date.
Property, plant and equipment; intangible assets	Property, plant and equipment; intangible assetsProperty, plant and equipment (excluding right-of-use assets) are recorded at historical cost. Self-constructed property, plant and equipment assets includes materials, direct labour and applicable overhead costs. Right-of-use assets, which are included in property, plant and equipment, are initially measured at cost, which includes the amount of lease liabilities recognized at the inception of the lease, initial direct costs incurred, and lease payments made at or before the lease commencement date less any lease incentives received. Subsequent to the initial recognition, right-of-use assets may be adjusted for any re-measurement of the corresponding lease liabilities.Intangible assets are recorded at historical cost. For internally-developed internal-use software, the historical cost recorded includes materials, direct labour and direct labour-related costs.
Lease liabilities	Lease liabilitiesLease liabilities are initially measured at the present value of lease payments to be made over the expected lease term. Lease payments include fixed payments, less any lease incentives or discounts. The expected lease term is the non-cancellable term of the lease, together with any periods covered by an option to extend the lease if it is reasonably certain to be exercised, considering all relevant factors and terms of the lease arrangement. In calculating the present value of lease payments, we use the interest rate implicit in the lease, if that rate can be readily determined, otherwise we use our incremental borrowing rate based on a similar security, term and economic environment. Subsequent to the initial recognition, we monitor for significant events or changes in circumstances that would require a change in the expected lease term, including a modification to the lease, and adjust the lease liability accordingly based on the change in present value of lease payments.
Business combinations	Business combinations We use the acquisition method to account for business combinations, under which we allocate the excess of the purchase price of business acquisitions over the fair value of identifiable net assets acquired to goodwill. The purchase price is determined as the fair value of assets transferred, liabilities assumed, or equity instruments issued on the date of exchange, which may include contingent considerations that are initially measured at fair value at the acquisition date. Subsequent changes to the fair value of any contingent considerations are recognized through profit or loss. Acquisition-related costs are expensed as incurred. For intangible assets acquired, the fair value is generally derived from a valuation analysis prepared by management or third-party experts as needed, based on appropriate valuation techniques using a forecast of the total expected future net cash flows and closely linked to the assumptions made by management regarding the future performance of the assets concerned and the discount rate applied. Where other markets or market participants are readily observable, these are considered in the determination of fair value. If the fair values of the assets, liabilities and contingent liabilities can only be calculated on a provisional basis, the business combination is recognized initially using provisional values. Any adjustments resulting from the completion of the measurement process are recognized within twelve months of the date of acquisition. Business transfers from related parties are accounted for as common control transactions using the predecessor accounting method wherein no assets or liabilities acquired are restated to their fair values and the results of operations include the transferred businesses’ results only from the date of our acquisition of them. No goodwill, except to the extent transferred as part of the transaction, is recognized on such transactions, and any excess purchase price is recorded as an adjustment to owners’ equity.

Changes in net income and/or other comprehensive income generally cannot be extrapolated because the relationship of the change in assumption to the change in net income and/or other comprehensive income may not be linear. In this table, the effect of a variation in a particular assumption on the amount of net income and/or other comprehensive income is calculated without changing any other factors; in reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities. The sensitivity analysis assumes that we would realize the changes in exchange rates; in reality, the competitive marketplace in which we operate would have an effect on this assumption. No consideration has been made for a difference in the notional number of common shares associated with share-based compensation awards made during the reporting period that may have arisen due to a difference in the common share price. (2) To facilitate ongoing comparison of sensitivities, a constant variance of approximate magnitude has been used. (3) The hypothetical effects of changes in the price of our subordinate voting shares and those of TELUS Corporation are limited to those which arise from our liability-accounted share-based compensation awards.
