Fair value hierarchy

The following is the hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 — other techniques for which all inputs have a significant effect on the recorded fair value are observable, either directly or indirectly.

Level 3 — techniques which use inputs that have a significant effect on the recorded fair value that are not based on observable market data.

The fair value is estimated using the discounted cash flow approach and market rates of interest. The valuation technique involves assumptions and judgments regarding risk characteristics of the instruments, discount rates and future cash flows.

The Company uses valuation techniques in measuring the fair value of financial instruments, where active market quotes are not available. In applying the valuation techniques, the Company makes maximum use of market inputs, and uses estimates and assumptions that are, as far as possible, consistent with observable data that market participants would use in pricing the instrument. Where applicable data is not observable, the Company uses its best estimate about the assumptions that market participants would make. These estimates may vary from the actual prices that would be achieved in an arm’s length transaction at the reporting date.

The assets and liabilities measured at fair value on a recurring basis as at March 31, 2023 are as follows:

Description of significant unobservable inputs to Level 3 valuation

The fair value of the contingent consideration liability for The Smart Cube, OptiBuy and Vuram was estimated using a probability weighted method and achievement of target revenues and adjusted EBITDA (with certain adjustments) with a discount rate of 2.75%, 4.93% and 2.90%, respectively. One percentage point change in the unobservable inputs used in fair valuation of the contingent consideration does not have a significant impact on its value.

The fair value is estimated using the discounted cash flow approach which involves assumptions and judgments regarding risk characteristics of the instruments, discount rates, future cash flows, foreign exchange spot, forward premium rates and market rates of interest.

The movement in contingent consideration categorised under Level 3 fair value measurement is given below:


	For the year ended
	March 31, 2023			March 31, 2022
Balance at the beginning of the year	$	—		$	—

Translation		184			—

Balance at the end of the year	$	42,256		$	—

During the years ended March 31, 2023 and 2022, there were no transfers between Level 1 and Level 2 fair value measurements, and no transfers into and out of Level 3 fair value measurements.

Derivative financial instruments

The primary risks managed by using derivative instruments are foreign currency exchange risk and interest rate risk. Forward and option contracts up to 24 months on various foreign currencies are entered into to manage the foreign currency exchange rate risk on forecasted revenue denominated in foreign currencies and monetary assets and liabilities held in

non-functional

currencies. Interest rate swaps are entered to manage interest rate risk associated with the Company’s floating rate borrowings. The Company’s primary exchange rate exposure is with the US dollar and pound sterling against the Indian rupee. For derivative instruments which qualify for cash flow hedge accounting, the Company records the effective portion of gain or loss from changes in the fair value of the derivative instruments in other comprehensive income/(loss), which is reclassified into earnings in the same period during which the hedged item affects earnings. Derivative instruments qualify for hedge accounting when the instrument is designated as a hedge; the hedged item is specifically identifiable and exposes the Company to risk; and it is expected that a change in fair value of the derivative instrument and an opposite change in the fair value of the hedged item will have a high degree of correlation. Determining the high degree of correlation between the change in fair value of the hedged item and the derivative instruments involves significant judgment including the probability of the occurrence of the forecasted transaction. When it is highly probable that a forecasted transaction will not occur, the Company discontinues the hedge accounting and recognizes immediately in the consolidated statement of income, the gains and losses attributable to such derivative instrument that were accumulated in other comprehensive income/(loss).

The following table presents the notional values of outstanding foreign exchange forward contracts and foreign exchange option contracts:


	As at
	March 31, 2023		March 31, 2022

The amount of gain/ (loss) reclassified from other comprehensive income into consolidated statement of income in respective line items for the years ended March 31, 2023, 2022 and 2021 are as follows:


	Year ended March 31,
	2023			2022			2021
Revenue	$	(2,185	)	$	3,451		$	4,237

Total	$	(3,617	)	$	2,177		$	3,980

As at March 31, 2023, a gain amounting to $3,721 on account of cash flow hedges in relation to forward and option contracts entered is expected to be reclassified from other comprehensive income into the consolidated statement of income over a period of 24 months.

Due to the discontinuation of cash flow hedge accounting on account of

non-occurrence

of original forecasted transactions by the end of the originally specified time period, the Company recognized in the consolidated statement of income a gain of Nil, a gain of $93 and a loss of $222 for the years ended March 31, 2023, 2022 and 2021, respectively. The loss of Nil each for the year

ended March 31, 2023 and March 31, 2022, respectively, and a loss of $222 for the year ended March 31, 2021 is due to the impact on account of

COVID-19.

Financial risk management

Financial risk factors

The Company’s activities expose it to a variety of financial risks: market risk, interest rate risk, credit risk and liquidity risk. The Company’s primary focus is to foresee the unpredictability of financial markets and seek to minimize potential adverse effects on its financial performance. The primary market risk to the Company is foreign exchange risk. The Company uses derivative financial instruments to mitigate foreign exchange related risk exposures. The Company’s exposure to credit risk is influenced mainly by the individual characteristic of each customer and the concentration of risk from the top few customers. The demographics of the customer including the default risk of the industry and country in which the customer operates also has an influence on credit risk assessment. The Company does not enter into or trade financial instruments, including derivative financial instruments, for speculative purposes.

Risk management procedures

The Company manages market risk through treasury operations. Senior management and the Board of Directors approve the Company’s treasury operations’ objectives and policies. The activities of treasury operations include management of cash resources, implementation of hedging strategies for foreign currency exposures, implementation of borrowing strategies and monitoring compliance with market risk limits and policies. The Company’s foreign exchange committee, comprising the Director nominated by the Board, Group Chief Executive Officer and Group Chief Financial Officer, is the approving authority for all hedging transactions.

Components of market risk

Exchange rate or currency risk

The Company’s exposure to market risk arises principally from exchange rate risk. Although substantially all of the Company’s revenue is denominated in pound sterling and US dollars, a significant portion of expenses for the year ended March 31, 2023 (net of payments to repair centers made as part of the Company’s WNS Auto Claims BPM segment) were incurred and paid in Indian rupees. The exchange rates among the Indian rupee, the pound sterling and the US dollar have changed substantially in recent years and may fluctuate substantially in the future. The Company hedges a portion of forecasted external and inter-company revenue denominated in foreign currencies with forward contracts and options.

Based upon the Company’s level of operations for the year ended March 31, 2023, a sensitivity analysis shows that a 10% appreciation or depreciation in the pound sterling against the US dollar would have increased or decreased, respectively, the Company’s revenue for the year ended March 31, 2023 by approximately $30,523. Similarly, a 10% appreciation or depreciation in the Indian rupee against the US dollar would have increased or decreased, respectively, the Company’s expenses incurred and paid in Indian rupee for the year ended March 31, 2023 by approximately $47,914.

As at March 31, 2023, every 10% appreciation or depreciation of the respective foreign currencies compared to the functional currency of the Company would impact the Company’s profit before tax from operating activities by approximately $2,130.

Interest rate risk

The Company’s exposure to interest rate risk arises from borrowings which have a floating rate of interest, which is linked to SOFR and SONIA. The risk is managed by the Company by maintaining an appropriate mix of fixed and floating rate borrowings and by the use of interest rate swap contracts. The costs of floating rate borrowings may be affected by the fluctuations in the interest rates. As at March 31, 2023, there was no amount outstanding under these swap agreements.

The Company monitors its positions and does not anticipate

non-performance

by the counterparties. The Company intends to selectively use interest rate swaps, options and other derivative instruments to manage exposure to interest rate movements. These exposures are reviewed by appropriate levels of management on a periodic basis. The Company does not enter into hedging agreements for speculative purposes.

Credit risk

Credit risk arises from the possibility that customers may not be able to settle their obligations as agreed. Trade receivables are typically unsecured and are derived from revenue earned from customers primarily located in the UK and the US. Credit risk is managed through periodic assessment of the financial reliability of customers, taking into account the financial condition, current economic trends, analysis of historical bad debts and ageing of trade receivables. The credit risk on marketable securities, FMPs, mutual funds, bank deposits and derivative financial instruments is limited because the counterparties are banks and mutual funds with high credit ratings assigned by international credit-rating agencies. The maximum exposure to credit risk at the reporting date is primarily from trade receivables and unbilled revenue which amounted to $113,107 and $99,785, respectively as at March 31, 2023 and $100,522 and $87,032, respectively, as at March 31, 2022.

The Company provides loss allowance using the ECL model on trade receivables and unbilled revenue with no significant financing component at an amount equal to lifetime ECL (Refer Note 7).

The following table gives details in respect of the percentage of revenue generated from the Company’s top customer and top five customers:


	Year ended March 31,
	2023			2022			2021
Revenue from top customer		6.5	%		7.3	%		8.1	%
Revenue from top five customers		23.8	%		27.1	%		26.8	%

Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company’s approach to managing liquidity risk is to ensure, as far as possible, that it will always have sufficient liquidity to meet its liabilities when due, under normal and stressed conditions, without incurring unacceptable losses or risking damage to its reputation. Typically, the Company ensures that it has sufficient cash on demand to meet expected operational expenses and service financial obligations. In addition, the Company has concluded arrangements with reputable banks and has unused lines of credit of $139,551

as at March 31, 2023 that could be drawn upon, should there be a need.

The assumptions used in accounting for the gratuity plans are as follows:


	Year ended March 31,
	2023		2022		2021
Discount rate:
India		7.4%		6.2% to 6.6%		6.4%
Philippines		5.9%		1.7%		3.1%
Sri Lanka		32.4%		16.4%		8.1%
Rate of increase in compensation level		7.0% to 14.0%		8.0% to 10.0%		7.0% to 8.0%
Expected rate of return on plan assets		7.4%		6.5% to 6.6%		6.4%

The Company evaluates these assumptions annually based on its long-term plans of growth and industry standards. The discount rates are based on current market yields on government securities adjusted for a suitable risk premium to reflect the additional risk for high quality corporate bonds.

As at March 31, 2023, for each of the Company’s defined benefit plans, the sensitivity of the defined benefit obligation to a change in each significant actuarial assumption is as follows:


	India			Philippines			Sri Lanka
Discount rate:
Increase in discount rate by 1%		(4.4	)%		(0.9	)%		(1.6	)%
Decrease in discount rate by 1%		4.8	%		1.0	%		1.7	%
Rate of increase in compensation level:
Increase in salary escalation rate by 1%		3.4	%		0.5	%		1.5	%
Decrease in salary escalation rate by 1%		(3.3	)%		(0.5	)%		(1.4	)%

Each sensitivity amount is calculated assuming that all other assumptions are held constant. The Company is not able to predict the extent of likely future changes in these assumptions, but based on past experience, the discount rate for each plan could change by up to 1% within a

12-month

period.

Plan assets are generally exposed to risk including market, interest and operating risk. Since the Company’s plan assets are managed by third party fund administrators, the contributions made by the Company are pooled with the corpus of the funds managed by such fund administrators and invested in accordance with regulatory guidelines. The Company’s funding policy is to contribute to the plan amounts necessary on an actuarial basis to, at a minimum, satisfy the minimum funding requirements. Additional discretionary contributions above the minimum funding requirement can be made and are generally based on adjustment for any over or under funding.

As at March 31, 2023, $1,442 and $1,285 ($1,162 and $1,583 as at March 31, 2022) of the plan assets are invested with LIC and ALICPL, respectively. Of the funds invested with LIC, approximately 40% and 60% of the funds are invested in unquoted government securities and money market instruments, respectively. Of the funds invested with ALICPL, approximately 76% and 24% are invested in unquoted government securities and money market instruments, respectively.

The expected benefits are based on the same assumptions used to measure the Company’s defined benefit obligations as at March 31, 2023. The Company expects to contribute $3,800 to defined benefit plan for the year ending March 31, 2024. The maturity analysis of the Company’s defined benefit payments is as follows:


	Amount
2024	$	3,800
2025		3,579
2026		3,454
2027		3,587
2028		3,892
Thereafter		18,640

Summary of significant accounting policies

2. Summary of significant accounting policies

a.	Basis of preparation

These consolidated financial statements have been prepared on a going concern basis, in compliance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standard Board (“IASB”).

These consolidated financial statements correspond to the classification provisions contained in IAS 1

(revised), “Presentation of Financial Statements.”

Accounting policies applied are consistent with the policies that were applied for the preparation of the consolidated financial statements for the year ended March 31, 2022.

b.	Basis of measurement

These consolidated financial statements have been prepared on a historical cost convention and on an accrual basis, except for the following material items that have been measured at fair value as required by relevant IFRS:

a.	Derivative financial instruments;

b.	Share-based payment transactions;

c.	Marketable securities and investments in mutual funds;

d.	Investments in fixed maturity plans (“FMPs”); and

e.	Contingent consideration.

c.	Use of estimates and judgments

The preparation of consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amount of assets, liabilities, income and expenses. Actual results may differ from those estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future period affected. In particular, information about significant areas of estimation, uncertainty and critical judgments in applying accounting policies that have the most significant effect on the amount recognized in the consolidated financial statements is included in the following notes:

Revenue recognition

The Company’s determination of whether BPM services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment.

The Company provides automobile claims handling services, wherein the Company enters into contracts with its clients to process all their claims over the contract period and the fees are determined either on a per claim basis or as a fixed payment for the contract period. Where the contracts are on a per claim basis, the Company invoices the client at the inception of the claim process. The Company estimates the processing period for the claims and recognizes revenue over the estimated processing period. This processing period generally ranges between one to two months. The processing time may be greater for new clients and the estimated service period is adjusted accordingly. The processing period is estimated based on historical experience and other relevant factors, if any.

ii.

Current income taxes

The major tax jurisdictions for the Company are India, the Philippines, South Africa, UK, and US, though the Company also files tax returns in other foreign jurisdictions. Significant judgments are involved in determining the provision for income taxes including judgment on whether tax positions are probable of being sustained in tax assessments. A tax assessment can involve complex issues, which can only be resolved over extended time periods. The recognition of taxes that are subject to certain legal or economic limits or uncertainties is assessed individually by management based on the specific facts and circumstances.

iii.

Deferred income taxes

The assessment of the probability of future taxable profit in which deferred tax assets can be utilized is based on the Company’s latest approved budget forecast, which is adjusted for significant

non-taxable

profit and expenses and specific limits to the use of any unused tax loss or credit. The tax rules in the numerous jurisdictions in which the Company operates are also carefully taken into consideration. If a positive forecast of taxable profit indicates the probable use of a deferred tax asset, especially when it can be utilized without a time limit, that deferred tax asset is usually recognized in full. The recognition of deferred tax assets that are subject to certain legal or economic limits or uncertainties is assessed individually by management based on the specific facts and circumstances.

iv.

Impairment

An impairment loss is recognized for the amount by which an asset’s or cash-generating unit’s carrying amount exceeds its recoverable amount. To determine the recoverable amount, management estimates expected future cash flows from each asset or cash-generating unit and determines a suitable interest rate in order to calculate the present value of those cash flows. In the process of measuring expected future cash flows management makes assumptions about future operating results. These assumptions relate to future events and circumstances. The actual results may vary, and may cause significant adjustments to the Company’s assets within the next financial year. The calculation of impairment loss involves significant estimates and assumptions which include revenue and earnings multiples, growth rates and net margins used to calculate projected future cash flows, risk-adjusted discount rate and future economic and market conditions.

In most cases, determining the applicable discount rate involves estimating the appropriate adjustment to market risk and the appropriate adjustment to asset-specific risk factors.

Valuation of derivative financial instruments

Management uses appropriate valuation techniques, such as binomial lattice model, in measuring the fair value of derivative financial instruments, where active market quotes are not available. In applying the valuation techniques, management makes maximum use of market inputs, and uses estimates and assumptions that are, as far as possible, consistent with observable data that market participants would use in pricing the instrument. Where applicable data is not observable, management uses its best estimate about the assumptions that market participants would make. These estimates may vary from the actual prices that would be achieved in an arm’s length transaction at the reporting date.

vi.

Accounting for defined benefit plans

In accounting for pension and post-retirement benefits, several statistical and other factors that attempt to anticipate future events are used to calculate plan expenses and liabilities. These factors include expected return on plan assets, discount rate assumptions and rate of future compensation increases. To estimate these factors, actuarial consultants also use estimates such as withdrawal, turnover, and mortality rates which require significant judgment. The actuarial assumptions used by the Company may differ materially from actual results in future periods due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates, or longer or shorter participant life spans.

vii.

Share-based compensation expense

The share-based compensation expense is determined based on the Company’s estimate of equity instruments that will eventually vest and valuation using the Monte-Carlo simulation and the binomial lattice model.

viii.

Business combinations

Business combinations are accounted for using the acquisition method under the provisions of IFRS 3 (Revised)

, “Business Combinations.”

The cost of an acquisition is measured at the fair value of the assets transferred, equity instruments issued, and liabilities incurred at the date of acquisition. The cost of the acquisition also includes the fair value of any contingent consideration. Identifiable tangible and intangible assets acquired, and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair value on the date of acquisition. Significant estimates are required to be made in determining the value of contingent consideration and intangible assets.

xi.

Impairment of

non-derivative

financial assets

The Company applies the forward-looking ECL model for recognizing impairment loss on financial assets that are measured at amortized cost or at fair value through other comprehensive income (“FVOCI”). Loss allowance for trade receivables and unbilled revenue with no significant financing component are measured at an amount equal to lifetime ECL. The Company applies the simplified approach for determining the lifetime ECL allowance using the Company’s historical credit loss experience adjusted for factors that are specific to the debtor.

For all other financial assets, the Company recognizes lifetime ECL when there has been a significant increase in credit risk since initial recognition. However, if the credit risk on the financial instruments has not increased significantly since the initial recognition, the Company measures the loss allowance for that financial instrument equal to

12-month

ECL. The impairment assessment is performed annually and the amount of ECL (or reversal) that is required to adjust the loss allowance at the reporting date is recognized as an impairment gain/loss under “General and administrative expenses” in the consolidated statement of income.

xii.

Leases

The Company determines the lease term as the

non-cancellable

period of a lease including any option to extend or terminate the lease, if the use of such option is reasonably certain. The Company makes an assessment on the expected lease term on a

lease-by-lease

basis and thereby assesses whether it is reasonably certain that any options to extend or terminate the contract will be exercised. In evaluating the lease term, the Company considers factors such as any significant leasehold improvements undertaken over the lease term, costs relating to the termination of the lease and the importance of the underlying asset to operations, taking into account the location of the underlying asset and the availability of suitable alternatives. The lease term in future periods is reassessed to ensure that the lease term reflects the current economic circumstances.

The Company has applied an incremental borrowing rate for the purpose of computing lease liabilities based on the rate prevailing in respective geographies.

d.	Basis of consolidation

The Company consolidates entities over which it has control. Control exists when the Company has existing rights that give the Company the current ability to direct the activities which affect the entity’s returns; the Company is exposed to or has rights to returns which may vary depending on the entity’s performance; and the Company has the ability to use its power to affect its own returns from its involvement with the entity. Subsidiaries are consolidated from the date control commences until the date control ceases.

Business combinations

Business combinations are accounted for using the acquisition method under the provisions of IFRS 3 (Revised)

, “Business Combinations.”

The cost of an acquisition is measured at the fair value of the assets transferred, equity instruments issued and liabilities incurred at the date of acquisition. The consideration of the acquisition also includes the fair value of any contingent consideration. Identifiable tangible and intangible assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair value on the date of acquisition. Significant estimates are required to be made in determining the value of contingent consideration and intangible assets.

Transaction costs that the Company incurs in connection with a business combination such as finders’ fees, legal fees, due diligence fees, and other professional and consulting fees are expensed as incurred.

ii.

Transactions eliminated on consolidation

All inter-company and intra-company balances, transactions, income and expenses including unrealized income or expenses are eliminated on consolidation.

e.	Functional and presentation currency

The financial statements of each of the Company’s subsidiaries are presented using the currency of the primary economic environment in which these entities operate (i.e. the functional currency). The consolidated financial statements are presented in US dollars (“USD”) which is the presentation currency of the Company and has been rounded off to the nearest thousands.

f.	Foreign currency transactions and translation

Transactions in foreign currency

Transactions in foreign currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at the exchange rates prevailing at the reporting date of monetary assets and liabilities denominated in foreign currencies are recognized in the consolidated statement of income. Gains/losses relating to translation or settlement of trading activities are disclosed under foreign exchange gains/losses and translation or settlements of financing activities are disclosed under finance expenses. In the case of foreign exchange gains/losses on borrowings that are considered as a natural economic hedge for the foreign currency monetary assets, such foreign exchange gains/losses, net are presented within results from operating activities.

ii.

Foreign operations

For the purpose of presenting consolidated financial statements, the assets and liabilities of the Company’s foreign operations that have local functional currency are translated into US dollars using exchange rates prevailing at the reporting date. Income and expense are translated at the monthly average exchange rate for the respective period. Exchange differences arising, if any, are recorded in equity as part of the Company’s other comprehensive income. Such exchange differences are recognized in the consolidated statement of income in the period in which such foreign operations are disposed. Goodwill and fair value adjustments arising on the acquisition of foreign operation are treated as assets and liabilities of the foreign operation and translated at the exchange rate prevailing at the reporting date.

Foreign currency exchange differences arising from intercompany receivables or payables relating to foreign operations, the settlement of which is neither planned nor likely to occur in the foreseeable future, are considered to form part of net investment in foreign operation and are recognized in foreign currency translation reserve.

g.	Financial instruments — initial recognition and subsequent measurement

Initial recognition

Trade receivables and unbilled revenue are initially recognized when they are originated. All other financial assets and financial liabilities are initially recognised when the Company becomes a party to the contractual provisions of the instrument.

Financial instruments are classified in the following categories:

•

Non-derivative

financial assets at amortized cost or at fair value through profit or loss (“FVTPL”).

•

Non-derivative

financial liabilities at FVTPL or at amortized cost.

•

Derivative financial instruments under the category of financial assets or financial liabilities at FVTPL or at FVOCI.

The classification of financial instruments depends on the purpose for which those were acquired. Management determines the classification of the Company’s financial instruments at initial recognition.

Non-derivative

financial instruments are recognized initially at fair value. Financial assets are derecognized when the contractual rights to the cash flows from the financial assets expire or when substantial risks and rewards of ownership of the financial asset have been transferred. In cases where substantial risks and rewards of ownership of the financial assets are neither transferred nor retained, financial assets are derecognized only when the Company has not retained control over the financial asset.

Financial liabilities are derecognized when the contractual obligations are discharged, cancelled or expired. The Company also derecognizes financial liabilities when their terms are modified and the cash flows of the modified liabilities are substantially different, in which case new financial liabilities based on the modified terms are recognized at fair value.

Subsequent to initial recognition,

non-derivative

financial instruments are measured as described below:

Non-derivative

financial assets

Financial assets at amortized cost

Financial assets that meet the following criteria are measured at amortized cost (except for investments that are designated at FVTPL on initial recognition):

the asset is held within a business model whose objective is to hold assets in order to collect contractual cash flows; and

ii)

the contractual terms of the instrument give rise on specified dates to cash flows that are solely payment of principal and interest on the principal amount outstanding.

Financial assets at amortized cost are presented as current assets, except for those maturing later than 12 months after the balance sheet date which are presented as

non-current

assets. They are measured initially at fair value plus transaction costs and subsequently carried at amortized cost using the effective interest rate method, less any impairment losses.

Financial assets at FVTPL

Financial assets that do not meet the amortized cost or FVOCI criteria are measured at FVTPL. Financial assets at FVTPL are measured at fair value at the end of each reporting period, with any gains or losses arising on

re-measurement

recognized in the consolidated statement of income. The gains or losses on disposal of financial assets at FVTPL are recognized in the consolidated statement of income.

Interest income on financial assets at FVTPL is recognized in the consolidated statement of income. Dividend on financial assets at FVTPL is recognized when the Company’s right to receive the dividend is established.

ii.

Non-derivative

financial liabilities

All financial liabilities are recognized initially at fair value, except in the case of loans and borrowings which are recognized at fair value, net of directly attributable transaction costs. The Company’s financial liabilities include trade and other payables, bank overdrafts, contingent consideration and loans and borrowings.

Trade and other payables maturing later than 12 months after the reporting date are presented as

non-current

liabilities.

After initial recognition, interest bearing loans and borrowings are subsequently measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the consolidated statement of income when the liabilities are derecognized as well as through the effective interest rate method amortization process.

After initial recognition, contingent consideration is subsequently measured at fair value and the changes to the fair value are recognized in the consolidated statement of income.

iii.

Derivative financial instruments and hedge accounting

The Company is exposed to foreign currency fluctuations on foreign currency assets, liabilities, net investment in foreign operations and forecasted cash flows denominated in foreign currency. The Company limits the effect of foreign exchange rate fluctuation by following established risk management policies including the use of derivatives. The Company enters into derivative financial instruments where the counterparty is primarily a bank. The Company holds derivative financial instruments such as foreign exchange forward and option contracts and interest rate swaps to hedge certain foreign currency and interest rate exposures.

Cash flow hedges

The Company recognizes derivative instruments as either assets or liabilities in the statement of financial position at fair value. Derivative instruments qualify for hedge accounting when the instrument is designated as a hedge; the hedged item is specifically identifiable and exposes the Company to risk; and it is expected that a change in fair value of the derivative instrument and an opposite change in the fair value of the hedged item will have a high degree of correlation.

For derivative instruments where hedge accounting is applied, the Company records the effective portion of derivative instruments that are designated as cash flow hedges in other comprehensive income/(loss) in the statement of comprehensive income, which is reclassified into earnings in the same period during which the hedged item affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion) or hedge components excluded from the assessment of effectiveness, and changes in fair value of other derivative instruments not designated as qualifying hedges is recorded as gains/losses, net in the consolidated statement of income. If the hedging instrument expires or is sold, terminated or exercised, the cumulative gain or loss on the hedging instrument recognized in the cash flow hedging reserve (in other comprehensive income/(loss)) until the period the hedge was effective remains in the cash flow hedging reserve until the forecasted transaction occurs. Cash flow hedge on interest rate swaps are recorded under finance expense, net. Cash flows from the derivative instruments are classified within cash flows from operating activities in the statement of cash flows.

When it is highly probable that a forecasted transaction will not occur, the Company discontinues the hedge accounting and recognizes immediately, in the consolidated statement of income, the gains and losses attributable to such derivative instrument that were accumulated in other comprehensive income/(loss).

Gains/(losses) on cash flow hedges on forecasted revenue transactions are recorded in foreign exchange gains/(losses) forming part of revenue. Changes in fair value of foreign currency derivative instruments not designated as cash flow hedges are recognized in the consolidated statement of income and reported within foreign exchange gains, net within results from operating activities.

iv.

Offsetting of financial instruments

Financial assets and financial liabilities are offset against each other and the net amount reported in the consolidated statement of financial position if, and only if, there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, or to realize the assets and settle the liabilities simultaneously.

Fair value of financial instruments

The fair value of financial instruments that are traded in active markets at each reporting date is determined by reference to quoted market prices or dealer price quotations, without any deduction for transaction costs. For financial instruments not traded in an active market, the fair value is determined using appropriate valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, credit risk, foreign exchange rates, and forward and spot prices for currencies.

vi.

Impairment of

non-derivative

financial assets

The Company applies the forward-looking ECL model for recognizing impairment loss on financial assets that are measured at amortized cost or at FVOCI. Loss allowance for trade receivables and unbilled revenue with no significant financing component are measured at an amount equal to lifetime ECL. The Company applies the simplified approach for determining the lifetime ECL allowance using the Company’s historical credit loss experience adjusted for factors that are specific to the debtor.

12-month

ECL. The impairment assessment is performed annually and the amount of ECL (or reversal) that is required to adjust the loss allowance at the reporting date is recognized as an impairment gain/loss under “ General and administrative expenses” in the consolidated statement of income.

h.	Equity and share capital

Share capital, share premium and treasury shares

The Company has only one class of equity shares. Par value of the equity share is recorded as the share capital and the amount received in excess of par value is classified as share premium. The credit corresponding to the share-based compensation expense and excess tax benefit related to the exercise of share options and restricted share units is recorded in share premium.

Treasury shares represent the consideration paid by the Company, including any directly attributable costs, to repurchase its own ordinary shares. Treasury shares are presented as a deduction from total equity. On cancellation of treasury shares, the amount paid is adjusted against share capital, to the extent of the par value of ordinary shares repurchased, and the balance is adjusted against share premium.

ii.

Retained earnings

Retained earnings comprise the Company’s undistributed earnings after taxes.

iii.

Other components of equity

Other components of equity consist of the following:

Cash flow hedging reserve

Changes in fair value of derivative hedging instruments designated and effective as a cash flow hedge are recognized net of taxes.

Foreign currency translation reserve

Foreign currency translation reserve consists of (i) the exchange difference arising from the translation of the financial statements of foreign subsidiaries and (ii) foreign currency differences arising from intercompany receivables or payables relating to foreign operations, the settlement of which is neither planned nor likely to occur in the foreseeable future, which are considered to form part of net investment in foreign operation.

Other Reserves

Other reserves include the Special Economic Zone

Re-Investment

Reserve created out of the profits of eligible Special Economic Zones (“SEZ”) units in terms of the provisions of the Indian

Income-tax

Act, 1961. Further, these provisions require the reserve to be utilized by the Company for acquiring new plant and machinery for the purpose of its business

Pension adjustments

This reserve represents cumulative actuarial gain and losses recognized, net of taxes on defined benefits plans.

i.	Cash and cash equivalents

The Company considers all highly liquid investments with an initial maturity of up to three months to be cash equivalents. Cash equivalents are readily convertible into known amounts of cash and subject to an insignificant risk of changes in value.

j.	Investments

Marketable securities and mutual funds

The Company’s marketable securities represent liquid investments and are acquired principally for the purpose of earning daily income. Investments in mutual funds represent investments in mutual fund schemes wherein the mutual fund issuer has invested these funds in enterprise development funds. Investments which are expected to be redeemed after 12 months from the reporting date are classified as

non-current

investments, otherwise they are classified as current investments.

These investments are designated at fair value through profit or loss and changes in fair value recognized in the consolidated statement of income. The fair value represents the original cost of the investment and the investment’s fair value at each reporting period.

ii.

Investments in fixed maturity plans

The Company’s investments in FMPs represent investments in mutual fund schemes wherein the mutual fund issuer has invested these funds in certificates of deposits with banks in India. The investments in FMPs are designated as fair value through profit or loss and change in fair value is recognized in the consolidated statement of income. The fair value represents original cost of an investment and the investment’s fair value at each reporting period or net asset value as quoted.

The Company manages FMPs on a fair value basis in accordance with the entity’s documented risk management, investment strategy and information provided to the key managerial personnel. The returns on the investment are measured based on the fair value movement rather than looking at the overall returns on the maturity. The Company’s investment purchase and sale decisions are also based on the fair value fluctuations rather than a predetermined policy to hold the investment until maturity. Key management personnel believe that recording these investments through the consolidated statement of income would provide more relevant information to measure the performance of the investment.

iii.

Investments in fixed deposits

Investments in fixed deposits consist of term deposits with original maturities of more than three months with banks. These are designated as financial assets at amortized cost.

k.	Funds held for clients

Some of the Company’s agreements in the auto claims handling services allow the Company to temporarily hold funds on behalf of the client. The funds are segregated from the Company’s funds and there is usually a short period of time between when the Company receives these funds from the client and when the payments are made on their behalf.

l.	Property and equipment

Property and equipment are stated at historical cost. Cost includes expenditures directly attributable to the acquisition of the asset. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets, which are as follows:


Asset description	Asset life (in years)
Buildings		20
Computers and software		3-4
Furniture, fixtures and office equipment		2-5
Vehicles		3
Leasehold improvements		Lesser of estimated useful life or lease term

Assets acquired under finance leases are capitalized as assets by the Company at an amount equal to the fair value of the leased asset or, if lower, the present value of the minimum lease payments, each determined at the inception of the lease. Assets under finance leases and leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the assets.

Advances paid towards the acquisition of property and equipment and the cost of property and equipment not ready for use before the reporting date are disclosed as capital

work-in-progress

in Note 11.

The Company assesses property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. If any such indication exists, the Company estimates the recoverable amount of the asset. The recoverable amount of an asset or cash generating unit is the higher of its fair value less cost of disposal (“FVLCOD”) and its

value-in-use

(“VIU”). If the recoverable amount of the asset or the recoverable amount of the cash generating unit to which the asset belongs is less than its carrying amount, the carrying amount is reduced to its recoverable amount. The reduction is treated as an impairment loss and is recognized in the consolidated statement of income. If at the reporting date there is an indication that a previously assessed impairment loss no longer exists, the recoverable amount is reassessed and the impairment losses previously recognized are reversed such that the asset is recognized at its recoverable amount but not exceeding the written down value which would have been reported if the impairment losses had not been recognized initially.

Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the Company’s share of the net identifiable assets of the acquired subsidiary at the date of acquisition. Goodwill is allocated to the cash-generating units expected to benefit from the synergies of the combination for the purpose of impairment testing. Goodwill is tested, at the cash-generating unit (or group of cash generating units) level, for impairment annually or if events or changes in circumstances indicate that the carrying amount may not be recoverable. Goodwill is carried at cost less accumulated impairment losses. Impairment loss on goodwill is not reversed. See further discussion on impairment testing under “impairment of intangible assets and goodwill” below.

n.	Intangible assets

Intangible assets are recognized only when it is probable that the expected future economic benefits attributable to the assets will accrue to the Company and the cost can be reliably measured. Intangible assets acquired in a business combination are recorded at fair value using generally accepted valuation methods appropriate for the type of intangible asset. Intangible assets with definite lives are amortized over the estimated useful lives and are reviewed for impairment, if indicators of impairment arise. Intangible assets with indefinite lives are not amortized but instead are tested for impairment at least annually and written down to the fair value. See further discussion on impairment testing under “impairment of intangible assets and goodwill” below.

Software development costs

Costs incurred for developing software or enhancements to the existing software products to be sold and/or used for internal use are capitalized once the research phase is complete, technological feasibility and commercial feasibility has been established, future economic benefits are probable, the Company has an intention and ability to complete and use or sell the software and the costs can be measured reliably. Technological feasibility is established upon completion of a detailed design program or, in its absence, completion of a working model. Significant management judgments and estimates are required in the assessment of when technological feasibility is established, as well as in the ongoing assessment of the recoverability of capitalized costs. Costs that qualify as software development costs include external direct costs of materials and services utilized in developing or obtaining software and compensation and related benefits for employees who are directly associated with the software project. The capitalized costs are amortized on a straight-line basis over the estimated useful life. Costs associated with research phase activities, training, maintenance and all post-implementation stage activities are expensed as incurred.

The Company’s definite lived intangible assets are amortized over the estimated useful life of the assets on a straight-line basis, as given below.


Asset description	Weighted average amortization period (in months)
Customer contracts		60
Customer relationships		162
Covenant not-to-compete		33
Trade names		36
Technology		94
Software		47
Service mark		Indefinite useful life

o.	Impairment of intangible assets and goodwill

Goodwill is not subject to amortization and tested at least annually for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Intangible assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s FVLCOD and VIU. For the purposes of assessing impairment, assets are grouped at the cash generating unit level which is the lowest level for which there are separately identifiable cash flows. Impairment losses recognized in respect of cash generating units are allocated first to reduce the carrying amount of any goodwill allocated to the cash generating units (or group of cash generating units) and then, to reduce the carrying amount of the other assets in the cash generating unit (or group of cash generating units) on a pro rata basis based on the carrying amount of each asset in the cash generating unit. Intangible assets except goodwill that suffered impairment are reviewed for possible reversal of the impairment at each reporting date.

p.	Employee benefits

Defined contribution plans

US savings plan

Eligible employees of the Company in the US participate in a savings plan (“the Plan”) under Section 401(k) of the United States Internal Revenue Code (“the Code”). The Plan allows for employees to defer a portion of their annual earnings on a

pre-tax

basis through voluntary contributions to the Plan. The Plan provides that the Company can make optional contributions up to the maximum allowable limit under the Code.

UK pension scheme

Eligible employees in the UK contribute to a defined contribution pension scheme operated in the UK. The assets of the scheme are held separately in an independently administered fund. The pension expense represents contributions payable to the fund maintained by the Company.

Provident fund

Eligible employees of the Company in India, the Philippines, South Africa, Sri Lanka and the UK participate in a defined contribution fund in accordance with the regulatory requirements in the respective jurisdictions. Both the employee and the Company contribute an equal amount to the fund which is equal to a specified percentage of the employee’s salary.

The Company has no further obligation under defined contribution plans beyond the contributions made under these plans. Contributions are charged to profit or loss and are included in the consolidated statement of income in the year in which they accrue.

ii.

Defined benefit plan

Employees in India, the Philippines and Sri Lanka are entitled to a defined benefit retirement plan covering eligible employees of the Company. The plan provides for a

lump-sum

payment to eligible employees, at retirement, death, and incapacitation or on termination of employment, of an amount based on the respective employees’ salary and tenure of employment (subject to a maximum of approximately $24 per employee in India). In India contributions are made to funds administered and managed by the Life Insurance Corporation of India (“LIC”) and Aviva Life Insurance Company Private Limited (“ALICPL”) (together, the “Fund Administrators”) to fund the gratuity liability of an Indian subsidiary. Under this scheme, the obligation to pay gratuity remains with the Company, although the Fund Administrators administer the scheme. The Company’s Sri Lanka subsidiary, Philippines subsidiary and two Indian subsidiaries have unfunded gratuity obligations.

Gratuity liabilities are determined by actuarial valuation, performed by an independent actuary, at each reporting date using the projected unit credit method. The Company recognizes the net obligation of a defined benefit plan in its balance sheet as an asset or liability, as the case may be, in accordance with IAS 19

–

“Employee Benefits.”

The discount rate is based on the government securities yield. Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are recorded in other comprehensive income in the statement of comprehensive income in the period in which they arise.

iii.

Compensated absences

The Company’s liability for compensated absences is determined on the basis of an actuarial valuation using the projected unit credit method and is charged to consolidated statement of income in the year in which they accrue.

q.	Share-based payments

The grant date fair value of share-based payment grants given to employees is recognized as employee cost with a corresponding increase in equity. The Company accounts for share-based compensation expense relating to share-based payments using a fair value method in accordance with IFRS 2

“Share-based Payments.”

Grants issued by the Company vest in a graded manner. Under the fair value method, the estimated fair value of awards is charged to income over the requisite service period, which is generally the vesting period of the award, for each separately vesting portion of the award as if the award was, in substance, multiple awards.

The Company is required to estimate share-based compensation expense, net of estimated forfeiture and expectation of market and non-market conditions to be met. In determining the estimated forfeiture rate, the Company annually conducts an assessment of actual number of share-based payment grants that have been forfeited as well as those expected to be forfeited in the future. The Company considers factors such as the employee grade and historical experience while estimating expected forfeitures.

r.	Provisions and accrued expenses

A provision is recognized in the statement of financial position when the Company has a present legal or constructive obligation as a result of a past event, and it is probable that an outflow of economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. If the effect is material, provisions are recognized at present value by discounting the expected future cash flows at a

pre-tax

rate that reflects current market assessments of the time value of money.

Provisions for onerous contracts are recognized when the expected benefits to be derived by the Company from a contract are lower than the unavoidable costs of meeting the future obligations under the contract. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract. Before a provision is established, the Company recognizes any impairment loss on the assets associated with that contract.

s.	Revenue recognition

The Company derives revenue from BPM services, comprising back-office administration, data management, customer experience services management, and auto claims handling services.

Revenue from rendering services is recognized on an accrual basis when the promised services are performed for an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. Revenue from the end of last billing to the reporting date is recognized as unbilled revenue. Unbilled revenue for certain contracts is classified as contract assets, as the right to consideration is conditional on factors other than the passage of time. Revenue is net of value-added taxes and includes reimbursements of

out-of-pocket

expenses.

Revenue earned by back-office administration, data management and customer experience services management services

Back-office administration, data management and customer experience services contracts are based on the following pricing models:

per full-time-equivalent arrangements, which typically involve billings based on the number of full-time employees (or equivalent) deployed on the execution of the business process outsourced;

per transaction arrangements, which typically involve billings based on the number of transactions processed (such as the number of

e-mail

responses, or airline coupons or insurance claims processed);

subscription arrangements, which typically involve billings based on per member per month, based on contractually agreed rates;

fixed-price arrangements, which typically involve billings based on achievements of

pre-defined

deliverables or milestones;

outcome-based arrangements, which typically involve billings based on the business result achieved by our clients through our service efforts (such as measured based on a reduction in days sales outstanding, improvement in working capital, increase in collections or a reduction in operating expenses); or

other pricing arrangements, including cost-plus arrangements, which typically involve billing the contractually agreed direct and indirect costs and a fee based on the number of employees deployed under the arrangement.

Revenues under

time-and-material

contracts and subscription arrangements are recognized as the related services are provided in accordance with the client contract. Revenues are recognized on cost-plus contracts on the basis of contractually agreed direct and indirect costs incurred on a client contract plus an agreed upon profit

mark-up.

Revenues are recognized on unit-price based contracts based on the number of specified units of work delivered to a client.

Revenue for performance obligations that are satisfied over time is recognized in accordance with the methods prescribed for measuring the progress. The input method (cost or efforts expended) has been used to measure progress towards completion as there is a direct relationship between inputs and productivity.

In respect of arrangements involving

sub-contracting,

in part or whole of the assigned work, the Company evaluates revenues to be recognized under criteria established by IFRS 15

“Revenue from Contract with Customers (“IFRS 15”)

, application guidance in paragraphs B34 to B38

“Principal versus agent considerations.”

Contracts with customers include variability in transaction price primarily due to service level agreements, gain share, minimum commitment and volume discounts. Revenues relating to such arrangements are accounted for as variable consideration when the amount of revenue to be recognized can be estimated to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

Amounts billed or payments received, where revenue recognition criteria have not been met, are recorded as deferred revenue and classified as contract liabilities. These are recognized as revenue when all the recognition criteria have been met. The costs related to the performance of BPM services unrelated to transition services (discussed below) are fulfilment costs classified as contract assets and recognized in the consolidated statement of income when the conditions for revenue recognition have been met. Any upfront payment received towards future services is classified as a contract liability and is recognized in the consolidated statement of income over the period when such services are provided.

All incremental and direct costs incurred for acquiring contracts, such as certain sales commission, are classified as contract assets. Such costs are amortized over the expected life of the contract.

Other upfront fees paid to customers are classified as contract assets. Such costs are amortized over the life of the contract and recorded as an adjustment to the transaction price and reduced from revenue.

For certain BPM customers, the Company performs transition activities at the outset of entering into a new contract. The Company has determined these transition activities do not meet the criteria of IFRS 15 to be accounted for as a separate performance obligation and has deferred revenue attributable to these activities. Accordingly, transition revenues are classified as contract liabilities and are subsequently recognized ratably over the period in which the BPM services are performed. Costs related to such transition services are fulfillment costs which are directly related to the contract and result in generation or enhancement of resources and are expected to be recoverable under the contract and thereby classified as contract assets and are recognized ratably over the estimated life of the contract.

All contracts entered into by the Company specify the payment terms. Usual payment terms range between 30 to 60 days.

Revenue earned by auto claims handling services

Auto claims handling services include claims handling and administration (“Claims Handling”), car hire and arranging for repairs with repair centers across the UK and the related payment processing for such repairs (“Accident Management”). With respect to Claims Handling, the Company receives either a

per-claim

fee or a fixed fee. Revenue for per claim fee is recognized over the estimated processing period of the claim, which currently ranges from one to two months and revenue for fixed fee is recognized on a straight-line basis over the period of the contract. In certain cases, the fee is contingent upon the successful recovery of a claim on behalf of the customer. In these circumstances, the revenue is deferred until the contingency is resolved. Revenue in respect of car hire is recognized over the car hire term.

In order to provide Accident Management services, the Company arranges for the repair through a network of repair centers. The repair costs are invoiced to customers. In determining whether the receipt from the customers related to payments to repair centers should be recognized as revenue, the Company considers the criteria established by IFRS 15 under the application guidance in paragraphs B34 to B38

“Principal versus agent considerations.”

When the Company determines that it is the principal in providing Accident Management services, amounts received from customers are recognized and presented as third-party revenue and the payments to repair centers are recognized as cost of revenue in the consolidated statement of income. Factors considered in determining whether the Company is the principal in the transaction include whether:

the Company has the primary responsibility for providing the services,

the Company negotiates labor rates with repair centers, and

the Company is responsible for timely and satisfactory completion of repairs.

If there are circumstances where the above criteria are not met and therefore the Company is not the principal in providing Accident Management services, amounts received from customers are recognized and presented net of payments to repair centers in the consolidated statement of income. Revenue from Accident Management services is recorded net of the repairer referral fees passed on to customers.

Revenue from legal services in the Auto Claims BPM segment is recognized on the admission of liability by the third party to the extent of fixed fees earned at each stage and any further income on the successful settlement of the claim.

Incremental and direct costs incurred to contract with a claimant are classified as contract assets and amortized over the expected period of benefit, not exceeding 15 months. All other costs to the Company are expensed as incurred.

Leases

The Company leases most of its delivery centers and office facilities under operating lease agreements that are renewable on a periodic basis at the option of the lessor and the lessee. The lease agreements contain rent free periods and rent escalation clauses.

The Company assesses whether a contract contains a lease at the inception of the contract. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the company assesses whether: (i) the contract involves the use of an identified asset, (ii) the company has the right to obtain substantially all of the economic benefits from the use of the asset through the period of the lease, and (iii) the company has the right to direct the use of the asset.

At the date of commencement of the lease, the Company recognizes a ROU asset and a corresponding lease liability for all lease arrangements under which it is a lessee, except for short-term leases and low value leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. For short-term leases and low value leases, the Company recognizes the lease payments as an expense on a straight-line basis over the term of the lease.

The lease arrangements include options to extend or terminate the lease before the end of the lease term. ROU assets and lease liabilities include these options when it is reasonably certain that they will be exercised.

The ROU assets are initially recognized at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or prior to the commencement date of the lease plus any initial direct costs less any lease incentives. They are subsequently measured at cost less accumulated depreciation and impairment losses.

ROU assets are depreciated from the date of commencement of the lease on a straight-line basis over the shorter of the lease term and the useful life of the underlying asset.

The lease liability is initially measured at amortized cost at the present value of the future lease payments. For leases under which the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate based on the information available at the date of commencement of the lease in determining the present value of lease payments. Lease liabilities are remeasured with a corresponding adjustment to the related ROU asset if the Company changes its assessment as to whether it will exercise an extension or a termination option.

The Company accounts for a modification of a lease contract as a separate contract for an additional right of use not included in the original lease and the increase in lease payment is commensurate with the standalone price for the additional right of use, adjusted for the circumstances of the particular contract. Modifications which are not accounted for as a separate contract are reassessed as at the effective date of the modifications based on the modified terms and conditions and the facts and circumstances as at that date. Upon modification, the Company remeasures the lease liability to reflect changes to the remaining lease payments and discount rates and recognizes the amount of the remeasurement of the lease liability as an adjustment to the ROU assets. However, if the carrying amount of the ROU assets is reduced to zero as a result of modification, any remaining amount of the remeasurement is recognized as an expense in consolidated statement of income.

The Company has applied practical expedient under an amendment to IFRS 16 for

COVID-19

related rent concessions to determine whether the concession provided by lessor occurring as a direct consequence of the

covid-19

pandemic meets the conditions mentioned in paragraph 46B of the amendment and accounted the eligible concessions in the consolidated statement of income.

In the case of

sub-leases,

where the Company is an intermediate lessor, the lease is classified as a finance lease or operating lease. A

sub-lease

is classified as a finance or operating lease by reference to the

right-of-use

asset arising from the head lease. In the case of a finance lease, the Company has accounted for its interest in the head-lease and the

sub-lease

separately and recognized a net investment in the

sub-lease

accordingly. Rental income received from the

sub-lease

is treated as finance income in the consolidated statement of income. In case of an operating lease, rental income is recognized in the consolidated statement of income over the term of the

sub-lease.

u.	Finance expense

Finance expense comprises interest cost on borrowings, transaction costs, interest expense on lease liabilities and the gains/losses on settlement of related derivative instruments. The foreign exchange gains/losses on borrowings are considered as a natural economic hedge for the foreign currency monetary assets which are classified as foreign exchange gains/losses, net within results from operating activities. Borrowing costs are recognized in the consolidated statement of income using the effective interest method.

v.	Income taxes

Income tax comprises current and deferred tax. Income tax expense is recognized in the consolidated statement of income except to the extent it relates to items directly recognized in equity, in which case it is recognized in equity.

Current income tax

Current income tax for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities based on the taxable profit for the period. The tax rates and tax laws used to compute the amount are those that are enacted by the reporting date and applicable for the period. The Company offsets current tax assets and current tax liabilities where it has a legally enforceable right to set off the recognized amounts and where it intends either to settle on a net basis, or to realize the asset and liability simultaneously.

Significant judgments are involved in determining the provision for income taxes including judgment on whether tax positions are probable of being sustained in tax assessments. A tax assessment can involve complex issues, which can only be resolved over extended time periods. The recognition of taxes that are subject to certain legal or economic limits or uncertainties is assessed individually by management based on the specific facts and circumstances. Though the Company has considered all these issues in estimating its income taxes, there could be an unfavorable resolution of such issues that may affect results of the Company’s operations.

ii.

Deferred income tax

Deferred income tax is recognized using the balance sheet approach. Deferred income tax assets and liabilities are recognized for all deductible and taxable temporary differences arising between the tax bases of assets and liabilities and their carrying amount in financial statements, except when the deferred income tax arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and affects neither accounting nor taxable profits or loss at the time of transaction.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred income tax asset in respect of carry forward of unused tax credits and unused tax losses are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized.

The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilized.

The Company recognizes deferred tax liabilities for all taxable temporary differences except those associated with the investments in subsidiaries where the timing of the reversal of the temporary difference can be controlled and it is probable that the temporary difference will not reverse in the foreseeable future.

w.	Earnings per share

Basic earnings per share are computed using the weighted-average number of ordinary shares outstanding during the period. Diluted earnings per share is computed by considering the impact of the potential issuance of ordinary shares, using the treasury stock method, on the weighted average number of shares outstanding during the period, except where the results would be anti-dilutive.

x.	Government grants

The Company recognizes government grants only when there is reasonable assurance that the conditions attached to them shall be complied with, and the grants will be received. Government grants related to depreciable assets are treated as deferred income and are recognized in the consolidated statement of income on a systematic and rational basis over the useful life of the asset. Government grants related to revenue are recognized on a systematic basis in the consolidated statement of income, generally over the periods necessary to match them with the related costs that they are intended to compensate.

sub-leases,

where the Company is an intermediate lessor, the lease is classified as a finance lease or operating lease. A

*	Excludes South Africa, Research and Analytics, Technology services, Denali, HealthHelp, Vuram, The Smart Cube, OptiBuy and Insurance goodwill.

Key assumptions on which the Company has based its determination of VIUs include:

a)	Estimated cash flows for five years based on management approved internal budgets with extrapolation for the remaining period, wherever such budgets were shorter than five years period.

Terminal value arrived by extrapolating last forecasted year cash flows to perpetuity using long-term growth rates. These long-term growth rates take into consideration external macro-economic sources of data. Such long-term growth rate considered does not exceed that of the relevant business and industry sector.

c)	The discount rates used are based on weighted average cost of capital of a comparable market participant, which are adjusted for specific country risks.

The key assumptions used in performing the impairment test during the year ended March 31, 2023, by each CGU, were as follows:


	CGU’s
	WNS Global BPM*			South Africa			Denali			Research and Analytics			HealthHelp			Technology services			Vuram			Insurance			Smart Cube			Optibuy
Discount rate		14.3	%		17	%		11.5	%		14.3	%		11.5	%		11.6	%		13.5	%		14.3	%		12.0	%		11.6	%
Perpetual growth rate		4.0	%		3.0	%		2.5	%		4.0	%		2.5	%		2.0	%		3.0	%		4.0	%		3.0	%		2.5	%


	CGU’s
	WNS Global BPM*			South Africa			Denali			Research and Analytics			HealthHelp			Technology services
Discount rate		14.9	%		15.5	%		11.7	%		14.9	%		11.7	%		13.0	%
Perpetual growth rate		3.0	%		3.0	%		2.5	%		3.0	%		2.5	%		2.0	%

*	Excludes South Africa, Research and Analytics, Technology services, Denali, HealthHelp, Vuram, The Smart Cube, OptiBuy and Insurance CGUs.

The assumptions used were based on the Company’s management approved internal budgets. The Company projected revenue, operating margins and cash flows for a period of five years and applied a perpetual long-term growth rate thereafter.

In arriving at its forecasts, the Company considered past experience, economic trends and inflation as well as industry and market trends including the impact of

COVID-19.

The projections also took into account factors such as the expected impact from new client wins and expansion from existing client’s businesses and efficiency initiatives, and the maturity of the markets in which each business operates.

Based on the above, no impairment was identified during the year ended March 31, 2023, as the recoverable amount of the CGUs exceeded the carrying value.

An analysis of the calculation’s sensitivity to a change in the key parameters (revenue growth, operating margin, discount rate and perpetual growth rate) did not identify any probable scenarios where the other CGU’s recoverable amount would fall below its carrying amount.

4. Business Combinations

a)	The Smart Cube Limited

On December 16, 2022 (“Acquisition date”), the Company acquired all ownership interests of The Smart Cube Limited and its subsidiaries (“The Smart Cube”), which provide digitally led market intelligence and analytics solutions in four key areas including procurement and supply chain, commercial sales and marketing, digital and analytics, and strategy and investment research. The Smart Cube is expected to complement the Company’s existing offerings and strengthen the Company’s capabilities in high-end procurement and advanced analytics.

The acquisition was for a total consideration of $122,150, subject to adjustments for cash and working capital, including a contingent consideration of $15,761, payable over a period of 2 years and 5 months linked to The Smart Cube’s target revenues and adjusted EBITDA (with certain adjustments) as specified in the acquisition agreement. The fair value of the contingent consideration liability was estimated using Level 3 inputs which included an assumption for discount rate of 4.93%. The potential undiscounted amount for all future payments that the Company could be required to make under the contingent consideration arrangement is between $0 and $17,286. Further, deferred earn out of $4,913 is payable over a period of 2 years and 5 months commencing from the acquisition date, subject to continued employment. The Company has funded the acquisition primarily with a five year secured term loan.

The Company incurred acquisition related costs of $2,130, which have been included in “

general

and administrative expenses” in the consolidated statement of income.

The provisional accounting pending allocation under IFRS 3, “Business Combinations” is as follows:

Deferred tax liabilities		(7,414	)

Net assets acquired		35,331
Less: Purchase consideration		(122,150	)

Goodwill on acquisition	$	86,819

Goodwill is attributable mainly to expected synergies and assembled workforce arising from the acquisition. Goodwill arising from this acquisition is not expected to be deductible for tax purposes.

The purchase consideration has been allocated on a provisional basis based on management’s estimates. The Company is in the process of making a final determination of the fair value of assets and liabilities. Finalization of the purchase price allocation may result in certain adjustments to the above allocation and revision of amounts recorded as of March 31, 2023 to reflect the final valuation of assets acquired or liabilities assumed.

Impact of acquisition on the results of the Company:

The acquisition of The Smart Cube contributed $10,146 to the Company’s revenue for the year ended March 31, 2023, and $971 to the Company’s profit after tax for the year ended March 31, 2023.

b)	OptiBuy sp. z.o.o.

OptiBuy is expected to complement the Company’s existing offerings and strengthen the Company’s capabilities in high-end procurement services.

cquisition date linked to target adjusted EBITDA (with certain adjustments) as specified in the acquisition agreement. The fair value of the contingent consideration liability was estimated using Level 3 inputs which included an assumption for discount rate of 2.90%. The potential undiscounted amount for all future payments that the Company could be required to make under the contingent consideration arrangement and deferred consideration is between Euro 0 and Euro 6,000 ($0 and $6,313, based on the exchange rate on December 14, 2022).

New accounting pronouncements not yet adopted by the Company

12 Months Ended

Mar. 31, 2023

New accounting pronouncements not yet adopted by the Company

3. New accounting pronouncements not yet adopted by the Company

Certain new standards, interpretations and amendments to existing standards have been published that are mandatory for the Company’s accounting periods beginning on or after April 1, 2023 or later periods. Those which are considered to be relevant to the Company’s operations are set out below.

In January 2020, the IASB issued amendments to IAS 1 “

Presentation of Financial Statements

” regarding the ‘Classification of Liabilities as Current or

Non-current’.

The amendments in Classification of Liabilities as Current or

Non-current

(Amendments to IAS 1) affect only the presentation of liabilities in the statement of financial position, and not the amount or timing of recognition of any asset, liability, income or expenses, or the information that entities disclose about those items. The amendments:

•

clarify that the classification of liabilities as current or

non-current

should be based on rights that are in existence at the end of the reporting period and align the wording in all affected paragraphs to refer to the “right” to defer settlement by at least 12 months and make explicit that only rights in place “at the end of the reporting period” should affect the classification of a liability;

•

clarify that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability; and

•

make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services.

The above amendments are effective for annual reporting periods beginning on or after January 1, 2024 and are to be applied retrospectively. Early application is permitted.

The Company is currently evaluating the impact of these amendments on its consolidated financial statements.

ii.	In February 2021, the IASB issued “Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2)” in relation to determining which accounting policies are to be disclosed in the financial statements. These amendments:

•

require an entity to disclose its material accounting policy information instead of its significant accounting policies.

•

clarify that accounting policy information may be material because of its nature, even if the related amounts are immaterial; and also clarifies if users of an entity’s financial statements would need it to understand other material information in the financial statements;

•

clarify that accounting policy information is material; and

•

clarify that if an entity discloses immaterial accounting policy information, such information shall not obscure material accounting policy information.

The amendments are effective for annual periods beginning on or after January 1, 2023 and are to be applied prospectively. Early application is permitted.

These amendments will not have a material impact on the Company’s consolidated financial statements.

iii.	In February 2021, the IASB issued “Disclosure of Accounting Estimates (Amendments to IAS 8)” in relation to distinction between accounting policies and accounting estimates. These amendments:

•

replace the definition of change in accounting estimates with a definition of accounting estimate as “monetary amounts in financial statements that are subject to measurement uncertainty”;

•

clarify that a change in accounting estimate that results from new information or new developments is not the correction of an error. In addition, the effects of a change in an input or a measurement technique used to develop an accounting estimate are changes in accounting estimates if they do not result from the correction of prior period errors; and

•

state that a change in an accounting estimate may affect only the current period’s profit or loss, or the profit or loss of both the current period and future periods. It also requires that the effect of the change relating to the current period is recognized as income or expense in the current period and the effect, if any, on future periods is recognized as income or expense in those future periods.

The amendments are effective for annual periods beginning on or after January 1, 2023 and are to be applied prospectively. Early application is permitted.

These amendments will not have a material impact on the Company’s consolidated financial statements.

iv.

In May 2021, the IASB issued “Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendments to IAS 12)” to clarify the accounting for deferred tax on transactions such as leases and decommissioning obligations. These amendments clarify that the initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition.

The Company is required to apply the amendments to transactions that occur on or after the beginning of the earliest comparative period presented. The Company is required, at the beginning of the earliest comparative period presented, to recognize deferred tax for all temporary differences related to leases and decommissioning obligations and recognize the cumulative effect of initially applying the amendments as an adjustment to the opening balance of retained earnings at that date.

The amendments are effective for annual reporting periods beginning on or after January 1, 2023. Early adoption is permitted.

These amendments will not have a material impact on the Company’s consolidated financial statements.

v.	In September 2022, the IASB issued ‘Lease Liability in a Sale and Leaseback (Amendments to IFRS 16)’ with amendments to clarify:

•

the requirements that a seller-lessee uses in subsequently measuring sale and leaseback transactions that satisfy the requirements in IFRS 15 to be accounted for as a sale.

The amendments are effective for annual periods beginning on or after January 1, 2024. The Company is currently evaluating the impact of these amendments on its consolidated financial statements.

vi.	In October 2022, the IASB issued “Non-current Liabilities with Covenants (Amendments to IAS 1)” to clarify the conditions with which an entity must comply within twelve months after the reporting period affect the classification of a liability.

The amendments are effective for annual periods beginning on or after January 1, 2024.

The Company is currently evaluating the impact of these amendments on its consolidated financial statements.

Domestic taxes are Nil as the corporate rate of tax applicable to companies in Jersey, Channel Islands is 0%. Foreign taxes are based on applicable tax rates in each subsidiary’s jurisdiction.

From fiscal 2012 until the year ended March 31, 2023, the Company started operations in various delivery centers in Mumbai, Pune, Chennai, Gurgaon, Noida, India registered under the Special Economic Zone scheme. Some of these operations are eligible for a 100% income tax exemption for a period of five years from the date of commencement of operations expiring between fiscal 2022 and fiscal 2024. Following the expiry of the 100% income tax exemption, these operations are eligible for a 50% income tax exemption expiring between fiscal 2026 and fiscal 2034. The Company’s operations in Costa Rica are eligible for a 50% income tax exemption from fiscal 2018 to fiscal 2021. Between fiscal 2016 and fiscal 2022, the Company commenced operations in delivery centers in the Philippines that are eligible for various tax exemption benefits expiring between fiscal 2020 and fiscal 2026. Following the expiry of the tax benefits, income generated by our Philippines subsidiary, WNS Global Services Philippines Inc., will be taxed at the prevailing special tax rate, which is currently 5.0% on gross profit. As per The Corporate Recovery and Tax Incentives for Enterprises Act (“CREATE”) which is effective from April, 2021, enterprises will be taxed at 5% on gross profit for a fixed period of 10 years. Our operations in Sri Lanka were eligible to claim income tax exemption with respect to the profits earned from export revenue until fiscal 2018 and have been taxed at 14% on a net basis with effect from April 1, 2018 until December 31, 2019. From January 1, 2020, our operations in Sri Lanka are eligible to claim income tax exemption with respect to the profits earned from export revenue.

If the income tax exemptions described above were not available, the additional income tax expense at the respective statutory rates in India, Sri Lanka and Philippines would have been approximately $20,735, $20,885 and $11,102 for the years ended March 31, 2023, 2022 and 2021, respectively.

Net deferred tax assets	$	9,349		$	25,475

There are unused tax losses amounting to $11,657

as at March 31, 2023 (March 31, 2022: $18,709) for which no deferred tax asset has been recognized as these losses relate to a tax jurisdiction where the group entity has had past losses and there is no conclusive evidence to support the view that sufficient taxable profit will be generated by such group entity in the future to offset such losses. The expiry dates of the tax benefit for these losses depend on the local tax laws of the jurisdiction and, if not utilized, would expire on various dates starting from financial year 2024 to 2033. However, in the US, Germany, New Zealand, the Netherlands, Portugal and UK there is no expiry period for the unused tax losses.

Deferred income tax liabilities on earnings of the Company’s subsidiaries have not been provided as such earnings are deemed to be permanently reinvested in the business and the Company is able to control the timing of the reversals of temporary differences associated with these investments. Accordingly, temporary difference on which deferred tax liability has not been recognized amounts to $1,148,274, $984,475 and $840,607 as at March 31, 2023, 2022 and 2021, respectively.

From time to time, the Company receives orders of assessment from the Indian tax authorities assessing additional taxable income on the Company and/or its subsidiaries in connection with their review of their tax returns. The Company currently has orders of assessment outstanding for various years through fiscal 2018, which assess additional taxable income that could in the aggregate give rise to an estimated $6,902 (March 31, 2022: $24,718) in additional taxes, including interest of $1,863 (March 31, 2022: $6,214). These orders of assessment allege that the transfer prices the Company applied to certain of the international transactions between WNS Global and its other wholly-owned subsidiaries were not on arm’s length terms, disallow a tax holiday benefit claimed by the Company, deny the set off of brought forward business losses and unabsorbed depreciation and disallow certain expenses claimed as tax deductible by WNS Global. The Company has appealed against these orders of assessment before higher appellate authorities.

In addition, the Company has orders of assessment pertaining to similar issues that have been decided in favor of the Company by appellate authorities, vacating the tax demands of $79,797 (March 31, 2022: $71,712) in additional taxes, including interest of $28,638 (March 31, 2022: $25,481). The income tax authorities have filed or may file appeals against these orders at higher appellate authorities.

Uncertain tax positions are reflected at the amount likely to be paid to the taxation authorities. A liability is recognized in connection with each item that is not probable of being sustained on examination by taxing authority. The liability is measured using single best estimate of the most likely outcome for each position taken in the tax return. Thus, the provision would be the aggregate liability in connection with all uncertain tax positions. As at March 31, 2023, the Company had provided a tax reserve of $

9,942 (March 31, 2022: $10,216) primarily on account of the Indian tax authorities’ denying the set off of brought forward business losses and unabsorbed depreciation.

As at March 31, 2023, corporate tax returns for years ended March 31, 2020 and onward remain subject to examination by tax authorities in India.

Based on the facts of these cases, the nature of the tax authorities’ disallowances and the orders from appellate authorities deciding similar issues in favor of the Company in respect of assessment orders for earlier fiscal years and after consultation with the Company’s external tax advisors, the Company believes these orders are unlikely to be sustained at the higher appellate authorities. The Company has deposited $11,022 (March 31, 2022: $11,849) of the disputed amounts with the tax authorities and may be required to deposit the remaining portion of the disputed amounts with the tax authorities pending final resolution of the respective matters.

In addition, the Company currently has orders of assessment outstanding for various years from newly acquired entities pertaining to the pre-acquisition period, which assess additional taxable income that could in the aggregate give rise to an estimated $

769 in additional taxes, including interest of $379.

These orders of assessment allege that the tax holiday benefit claimed by the newly acquired entities should be disallowed. The newly acquired entities have appealed against these orders of assessment before higher appellate authorities.

Others

From time to time, the Company receives orders of assessment from the VAT, service tax and GST authorities, demanding payment of $1,942

towards VAT, service tax and GST for the period April 1, 2014 to March 31, 2019. The tax authorities have rejected input tax credit on certain types of input services. Based on consultations with the Company’s tax advisors, the Company believes these orders of assessments will more likely than not be vacated by the higher appellate authorities and the Company intends to dispute the orders of assessment.

Share-based payments

24. Share-based payments

The Company has two share-based incentive plans: the 2006 Incentive Award Plan adopted on June 1, 2006, as amended and restated in February 2009, September 2011 and September 2013 (which has expired) the “2006 Incentive Award Plan”, and the 2016 Incentive Award Plan effective from September 27, 2016, as amended and restated in September 2018 (the “2016 Incentive Award Plan”) (collectively referred to as the “Plans”). All the Plans are equity settled. Under the Plans, share-based options and RSUs may be granted to eligible participants. Options are generally granted for a term of ten years. Options and RSUs have a graded vesting period of up to four years. The Company settles employee share-based options and RSU exercises with newly issued ordinary shares. As at March 31, 2023, the Company had 1,881,518 ordinary shares available for future grants.

Share-based compensation expense during the years ended March 31, 2023, 2022 and 2021 is as follows:


	Year ended March 31,
	2023		2022		2021
Share-based compensation expense recorded in:	$		$		$
Cost of revenue		8,057		5,155		4,890
Selling and marketing expenses		6,411		4,948		4,327
General and administrative expenses		35,265		34,062		29,013

Total share-based compensation expense	$	49,733	$	44,165	$	38,230

Upon exercise of RSUs, the Company issued 610,910, 547,704 and 768,563 shares during the years ended March 31, 2023, 2022 and 2021, respectively.

Restricted share units

The 2006 Incentive Award Plan and the 2016 Incentive Award Plan also allow for the grant of RSUs. Each RSU represents the right to receive one ordinary share and vests over a period of up to three years.

(i)	Movements in the number of RSUs dependent on non-market performance condition outstanding under the 2006 Incentive Award Plan and the 2016 Incentive Award Plan and their related weighted average fair values are as follow:


	Shares			Weighted average fair value		Aggregate intrinsic value
Outstanding as at March 31, 2021		924,049		$	44.25	$	66,938
Granted		295,441			74.14
Exercised		(293,769	)		47.24
Forfeited		(40,264	)		56.52

Outstanding as at March 31, 2022		885,457		$	52.67	$	75,698
Granted		428,238			83.70
Exercised		(255,200	)		59.34
Forfeited		(25,777	)		73.02

Outstanding as at March 31, 2023		1,032,718		$	63.38	$	96,218
RSUs exercisable		575,146		$	50.70	$	53,586

The fair value of RSUs is generally the market price of the Company’s shares on the date of grant. As at March 31, 2023, there was $15,322 of unrecognized compensation cost related to unvested RSUs. This amount is expected to be recognized over a weighted average period of 2.8 years. To the extent the actual forfeiture rate is different than what the Company has anticipated, share-based compensation expense related to these RSUs will be different from the Company’s expectations.

The weighted average grant date fair value of RSUs granted during the year ended March 31, 2023, 2022 and 2021 was $83.70, $74.14 and $43.26, per ADS, respectively. The aggregate intrinsic value of RSUs exercised during the year ended March 31, 2023, 2022 and 2021 was $21,438, $23,194 and $20,354, respectively. The total grant date fair value of RSUs vested during the year ended March 31, 2023, 2022 and 2021 was $21,484, $18,240 and $15,912, respectively.

The weighted average share price of RSUs exercised during the year ended March 31, 2023, 2022 and 2021 was $84.01, $78.95 and $66.77, respectively.

(ii)	The 2006 Incentive Award Plan and the 2016 Incentive Award Plan also allow for the grant of RSUs based on the market price of the Company’s shares achieving a specified target over a period of time. The fair value of market-based share awards is determined using Monte-Carlo simulation.


	Shares			Weighted average fair value		Aggregate intrinsic value
Outstanding as at March 31, 2021		75,645		$	14.10	$	5,480
Exercised		(16,245	)		13.39

Outstanding as at March 31, 2022		59,400		$	14.30	$	5,078
Exercised		(761	)		14.30

Outstanding as at March 31, 2023		58,639			14.30	$	5,463
RSUs exercisable		58,639		$	14.30	$	5,463

On March 15, 2017, the Company modified the vesting period in respect of the RSUs as follows:

a.	for RSUs granted in April 2014, the vesting date has been extended to the fifth anniversary of the grant date (i.e. April 2019).

b.	for RSUs granted in April 2015, the vesting date has been extended to the fourth anniversary of the grant date (i.e. April 2019).

c.	for RSUs granted in April 2016, the vesting date has been extended to the fourth anniversary of the grant date (i.e. April 2020).

Subsequent vesting of RSUs for each of the remaining years would be subject to continued employment.

The incremental fair value was determined using Monte-Carlo simulation by reference to the difference between fair value of original RSUs as at modification date and the fair value of modified RSUs as at modification date. The additional cost as a result of such modification in respect of modified share awards amounted to $1,185. The additional cost is spread over the period from the modification date until the vesting date of the modified award, which differs from the vesting date of the original award. The incremental cost recognized in the current year (March 31, 2022: $Nil) in respect of such modified share awards amounted to $Nil.

The aggregate intrinsic value of RSUs exercised during the year ended March 31, 2023, 2022 and 2021 was $69, $1,205 and $8,973, respectively. The weighted average share price of RSU exercised during the year ended March 31, 2023, 2022 and 2021 was $90.98, $74.18 and $72.75, respectively.

As at March 31, 2023, there was $Nil of unrecognized compensation cost related to unvested market based RSUs. The weighted average grant date fair value of the RSUs granted during the years ended March 31, 2023, 2022 and 2021 was $Nil.

(iii)

RSUs related to total shareholder’s return (“TSR”)

Movements in the number of RSUs linked to the TSR condition outstanding under the 2016 Incentive Award Plan and their related weighted average fair values are as follows:


	Shares			Weighted Average fair value		Aggregate Intrinsic value
Outstanding as at March 31, 2021		826,210		$	45.45	$	59,851
Granted		154,110			78.80
Exercised		(15,209	)		50.22

Granted		104,975			79.00
Exercised		(165,201	)		37.87
Forfeited		(22,480	)		58.28
Lapsed		(26,236	)		63.10

Outstanding as at March 31, 2023		790,508			56.32		73,652
RSUs exercisable		256,135		$	58.05	$	23,864

During the year ended March 31, 2023, the Company issued 104,975 RSUs (March 31, 2022: 154,110 RSUs) to certain employees. The conditions for the vesting of these RSUs are linked to the TSR of the Company in addition to the condition of continued employment with the Company through the applicable vesting period.

The performance of these RSUs shall be assessed based on the TSR of the custom peer group (based on percentile rank) and the industry index (based on outperformance rank). The RSUs granted with the TSR condition shall vest on the third anniversary of the grant date, subject to the participant’s continued employment with the Company through the applicable vesting date and achievement of the specified conditions of stock performance and TSR parameters.

The fair value of these RSUs is determined using Monte-Carlo simulation. The weighted average grant date fair value of RSUs granted during the year ended March 31, 2023, 2022 and 2021 was $79.00, $78.80 and $35.22, per ADS, respectively. The stock compensation expense charged during the year ended March 31, 2023 was $5,123 (March 31, 2022: $5,892). As at March 31, 2023, there was $5,062 of unrecognized compensation cost related to these RSUs. This amount is expected to be recognized over a weighted average period of 1.8 years. The total grant date fair value of these RSUs vested during the year ended March 31, 2023, 2022 and 2021 was $9,395, $5,338 and $7,651, respectively.

The aggregate intrinsic value of RSUs exercised during the year ended March 31, 2023, 2022 and 2021 was $14,448, $1,201, and $1,413, respectively. The weighted average share price of RSU exercised during the year ended March 31, 2023, 2022 and 2021 was $87.45, $78.97 and $74.20, respectively.

Performance share units

The 2006 Incentive Award Plan and 2016 Incentive Award Plan also allow for grant of performance share units (“PSUs”). Each PSU represents the right to receive one ordinary share based on the Company’s performance against specified

non-market

performance conditions and vests over a period of three years.

Movements in the number of PSUs outstanding under the 2006 Incentive Award Plan and the 2016 Incentive Award Plan and their related weighted average fair values are as follow:


	Shares			Weighted average fair value		Aggregate intrinsic value
Outstanding as at March 31, 2021		771,289		$	43.21	$	55,870
Granted		275,245			73.46
Exercised		(192,053	)		35.65
Forfeited		(16,173	)		60.58

Outstanding as at March 31, 2022		838,308		$	49.19	$	71,667
Granted		202,005			84.00
Exercised		(189,226	)		44.59
Forfeited		(13,996	)		72.81

Outstanding as at March 31, 2023		837,091			55.30		77,992
PSUs exercisable		428,090		$	47.13	$	39,885

The fair value of PSUs is generally the market price of the Company’s shares on the date of grant, and assumes that performance targets will be achieved. As at March 31, 2023, there was $11,500 of unrecognized compensation costs related to unvested PSUs, net of forfeitures. This amount is expected to be recognized over a weighted average period of 1.7 years. Over the performance period, the number of shares that will be issued will be adjusted upward or downward based upon the probability of achievement of the performance targets. The ultimate number of shares issued and the related compensation cost recognized as expense will be based on a comparison of the final performance metrics to the specified targets.

The weighted average grant date fair value of PSUs granted during the years ended March 31, 2023, 2022 and 2021 was $84.00, $73.46 and $68.05, per ADS, respectively. The aggregate intrinsic value of PSUs exercised during the year ended March 31, 2023, 2022 and 2021 was $15,970, $14,958 and $22,207, respectively. The total grant date fair value of PSUs vested during the year ended March 31, 2023, 2022 and 2021 was $17,686, $13,599 and $13,049 respectively.

The weighted average share price of PSU exercised during the year ended March 31, 2023, 2022 and 2021 was $84.40, $77.89 and $69.10, respectively.

BBBEE program in South Africa

The Company’s South African subsidiary has issued share appreciation rights to certain employees to be settled with the Company’s shares. As part of the settlement, the Company granted 1,135 RSUs during the year ended March 31, 2022 and 11,400 and 1,850 RSUs during the year ended March 31, 2021 which shall vest on the second anniversary, nine months and third anniversary, respectively, from the grant date. During the years ended March 31, 2020, 2019 and 2018, the Company granted 3,365, 14,250 and 32,050 RSUs, which shall vest on the fourth, third and fourth anniversaries, respectively, from the grant date, subject to such grantee’s continued employment with the Company through the applicable vesting date. The grant date fair value was estimated using a binomial lattice model.

The total stock compensation expense in relation to these RSUs was $3,483 to be amortized over the vesting period of four years.

The stock compensation expense charged during the years ended March 31, 2023, 2022 and 2021 was $111, $

324 and $871, respectively.

RSUs to drive higher growth

During the year ended March 31, 2023, the Company granted 705,090 RSUs to drive higher growth, based on performance and market conditions along with service conditions. The RSUs under this grant will vest upon the Company achieving the market capitalization target along with net revenue targets (together referred as the “vesting conditions”). The vesting period ranges from 2 years and 9 months to 4 years and 9 months from the grant date dependent on achievement of respective vesting conditions at each evaluation period. The vesting of RSUs will happen only on achievement of both the vesting conditions. Any unvested RSUs due to non-achievement of vesting conditions at the end of vesting period will lapse.

The fair value of these RSUs is determined using the Monte-Carlo simulation. The grant date fair value of RSUs granted was $28.00 per RSU.

During the year ended March 31, 2023, the Company modified the terms of the original grant to increase the vesting period.

Operating segments

28. Operating segments

The Company has several operating segments based on a mix of industry and the types of services. The composition and organization of these operating segments currently is designed in such a way that the back office shared processes, i.e. the horizontal structure, delivers service to industry specific back office and front office processes i.e. the vertical structure. These structures represent a matrix form of organization structure, accordingly operating segments have been determined based on the core principle of segment reporting in accordance with IFRS 8

“Operating segments”

(“IFRS 8”). Segment managers are responsible for the performance of the operating segments on a combined vertical structure which includes travel and leisure, shipping and logistics services; utilities, retail and consumer products group; banking and financial, healthcare and insurance services including auto claims;

hi-tech

and professional services; and others. Effective February 1, 2019, the Company realigned its segment managers responsible for the performance of operating segments on a combined vertical structure with the appointment of a segment manager as Chief Operating Officer. The revised structure includes travel and leisure, shipping and logistics services; utilities; retail and consumer products group; banking and financial services;

hi-tech

and professional services; insurance services; healthcare; auto claims and others. The segment managers’ performance is reviewed by the Group Chief Executive Officer, who has been identified as the Chief Operating Decision Maker (“CODM”). The CODM evaluates the Company’s performance and allocates resources based on revenue growth of combined vertical structure.

The Company believes that the business process management services that it provides to customers in industries other than auto claims such as travel and leisure, shipping and logistics services; utilities, retail and consumer products group; banking and financial, healthcare and insurance;

hi-tech

and professional services; and others are similar in terms of services, service delivery methods, use of technology, and average long-term gross profit and hence meet the aggregation criteria in accordance with IFRS 8. WNS Assistance Limited and Accidents Happen Assistance Limited (which provide automobile repair through a network of third party repair centers), and WNS Assistance (Legal) Limited and WNS Legal Assistance LLP (which provide legal services in relation to personal injury claims), constitute WNS Auto Claims BPM, the performance of which is evaluated by the CODM separately. The WNS Auto Claims BPM segment does not meet the aggregation criteria. Accordingly, the Company has determined that it has two reportable segments, “WNS Global BPM” and “WNS Auto Claims BPM.”

In order to provide accident management services, the Company arranges for the repair through a network of repair centers. Repair costs paid to automobile repair centers are invoiced to customers and recognized as revenue except in cases where the Company has concluded that it is not the principal in providing claims handling services and hence it would be appropriate to record revenue from repair services on a net basis, i.e. net of repair cost. The Company uses revenue less repair payments

(non-GAAP)

for “Fault” repairs as a primary measure to allocate resources and measure segment performance. Revenue less repair payments is a

non-GAAP

measure which is calculated as (a) revenue less (b) in the Company’s auto claims business, payments to repair centers for “Fault” repair cases where the Company acts as the principal in its dealings with the third party repair centers and its clients. For

“Non-fault

repairs,” revenue including repair payments is used as a primary measure. As the Company provides a consolidated suite of accident management services including credit hire and credit repair for its

“Non-fault”

repairs business, the Company believes that measurement of that line of business has to be on a basis that includes repair payments in revenue.
