(Unaudited)

These condensed consolidated financial statements should be read in conjunction with the financial statements of the Bank included in its Form 20-F filed with the Securities and Exchange Commission on July 28, 2021.

1. Summary of significant accounting policies

a. Principles of consolidation

The consolidated financial statements include the accounts of HDFC Bank Limited and its subsidiaries. The Bank consolidates subsidiaries in which, directly or indirectly, it holds more than 50% of the voting rights and/or has control. Entities where the Bank holds 20% to 50% of the voting rights and/or has the ability to exercise significant influence are accounted for under the equity method. These investments are included in other assets and the Bank’s proportionate share of income or loss is included in Non-interest revenue, other. The Bank consolidates Variable Interest Entities (“VIEs”) where the Bank is determined to be the primary beneficiary. All significant inter-company balances and transactions are eliminated on consolidation.

b. Basis of presentation

These financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“US GAAP”). US GAAP differs in certain material respects from accounting principles generally accepted in India, the requirements of India’s Banking Regulation Act, 1949 and related regulations issued by the Reserve Bank of India (“RBI”) (collectively “Indian GAAP”), which form the basis of the statutory general purpose financial statements of the Bank in India. Principal differences, insofar as they relate to the Bank, include: determination of the allowance for credit losses, classification and valuation of investments, accounting for deferred taxes, stock-based compensation, loan origination fees, derivative financial instruments, business combination, lease accounting and the presentation format and disclosures of the financial statements and related notes.

c. Use of estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of these financial statements and the reported amounts of revenues and expenses for the years presented. Actual results could differ from these estimates. Material estimates in these financial statements that are susceptible to change include the allowance for credit losses, the valuation of unquoted investments, impairment in securities, valuation of derivatives, stock-based compensation, unrecognized tax benefits, valuation of lease liabilities and impairment assessment of goodwill.

d. Investments in securities

Investments consist of securities purchased as part of the Bank’s treasury operations, such as government securities and other debt securities, and investments purchased as part of the Bank’s wholesale banking operations, such as credit substitute securities issued by the Bank’s wholesale banking customers.

Credit substitute securities typically consist of commercial paper and debentures issued by the same customers with whom the Bank has a lending relationship in its wholesale banking business. Investment decisions for credit substitute securities are subject to the same credit approval processes as for loans, and the Bank bears the same customer credit risk as it does for loans extended to those customers. Additionally, the yield and maturity terms are generally directly negotiated by the Bank with the issuer. All other securities including mortgage- and asset-backed securities are actively managed as part of the Bank’s treasury operations. The issuers of such securities are either government, public financial institutions or private issuers. These investments are typically purchased from the market, and debt securities are generally publicly rated.

Securities that are held principally for resale in the near term are classified as held for trading (“HFT”) and are carried at fair value, with changes in fair value recorded in net income.

Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity (“HTM”) and are carried at amortized cost.

(Unaudited)

All debt securities that are not classified as HTM or HFT are classified as available for sale debt securities (“AFS”) and are carried at fair value. Unrealized gains and losses on such securities, net of applicable taxes, are reported in accumulated other comprehensive income (loss), a separate component of shareholders’ equity.

Equity securities are classified under other assets. Marketable securities are measured at fair value, change in fair value recorded in earnings. Non-marketable equity securities under the measurement alternative are carried at cost plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer and impairment, if any. The Bank’s review for impairment for equity method, cost method and measurement alternative securities typically includes an analysis of the facts and circumstances of each security, the intent or requirement to sell the security, and the expectations of cash flows.

Fair values are based on market quotations where a market quotation is available or otherwise based on present values at current interest rates for such investments.

Transfers between categories are recorded at fair value on the date of the transfer.

e. Impairment of debt securities

Up to March 31, 2020, declines in the fair values of held to maturity and available for sale debt securities below their carrying value that were other than temporary were reflected in net income as other than temporary impairment losses, based on management’s best estimate of the fair value of the investment. The Bank conducted a review each year to identify other than temporary declines based on an evaluation of all significant factors. The Bank’s review of impairment generally entailed identification and evaluation of investments that had indications of possible impairment, analysis of evidential matter, including an evaluation of factors or triggers that would or could cause individual investments to have other than temporary impairment and documentation of the results of these analyses, as required under business policies. Estimates of any declines in the fair values of credit substitute securities that were other than temporary were measured on a case-by-case basis together with loans to those customers. The Bank did not recognize an impairment for debt securities if the cause of the decline was related solely to interest rate increase and the Bank did not intend to sell the security and it was not more likely than not that the Bank would be required to sell the security before recovery of its amortized cost basis.

The Bank adopted ASU 2016-13 “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”)” with effect from April 1, 2020. The Bank conducts a review of all available for sale debt securities with fair value below their carrying value or with zero loss expectation. The Bank evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If the assessment indicates that a credit loss exists, the present value of cash flows to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded through a provision for credit loss expense, limited by the amount that fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. The allowance is increased or decreased if credit conditions subsequently worsen or improve. A reversal of credit losses is recognized in earnings. The Bank recognizes the entire difference between amortized cost basis and fair value in earnings for impaired AFS debt securities that the Bank has an intent to sell or for which the Bank believes it will more likely than not be required to sell prior to recovery of the amortized cost basis. The Bank applied ASC 326 to AFS debt securities when Other Than Temporary Impairment has been recognized before the adoption. Amortized cost of a security, including the security’s effective interest rate where an other-than-temporary impairment had been recognized up to March 31, 2020 has remained unchanged. Amounts previously recognized in accumulated other comprehensive income as of the adoption date that relate to improvements in cash flows continue to be accreted to interest income over the remaining life of the security on a level-yield basis. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption are recorded to income in the period received. The Bank does not record an allowance on accrued interest receivables on the balance sheet due to its policy to reverse interest income on debt securities in a timely manner in line with the Bank’s non-accrual and past due policies and also on any debt security classified as non-performing. The Bank does not purchase debt securities with credit deterioration.

f. Loans

The Bank grants retail and wholesale loans to customers.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for an allowance for credit losses. Loan origination fees and certain direct origination costs are deferred and recognized as adjustments to net income over the lives of the related loans.

Interest is accrued on the unpaid principal balance and is included in interest income. Loans are generally placed on “non-accrual” status when interest or principal payments are three months past due or if they are considered non-performing, at which time no further interest is accrued and any unrealized interest recognized in the income statement is reversed. Interest income and principal payments on loans placed on non-accrual status is recognized when received. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current, and future payments are reasonably assured.

g. Allowance for credit losses

The Bank provides an allowance for credit losses based on management’s best estimate of losses inherent in the loan portfolio which includes troubled debt restructuring. The allowance for credit losses consists of allowances for retail loans and wholesale loans. Upon adoption of ASC 326, the Bank revised its accounting policy for Allowance for credit losses as detailed below:

Retail

Up to March 31, 2020 the Bank’s retail loan loss allowance consisted of specific allowance and allowance for loans collectively evaluated for impairment (termed as “unallocated allowance”). The Bank established a specific allowance on the retail loan portfolio based on factors such as the nature of the product, delinquency levels or the number of days the loan is past due and the nature of the security available. Additionally, the Bank monitored loan to value ratios for loans against securities. The loans were charged off against allowances typically when the account became 150 to 1,083 days past due depending on the type of loan. The defined delinquency levels at which major loan types are charged off were 150 days past due for personal loans, credit card receivables, auto loans, commercial vehicle and construction equipment finance, 720 days past due for housing loans and on a customer by customer basis in respect of retail business banking when management believed that any future cash flows from these loans were remote including realization of collateral, if applicable, and where any restructuring or any other settlement arrangements were not feasible. Subsequent recoveries, if any, against write-off cases, were adjusted to provision for credit losses in the consolidated statement of income. The Bank also recorded unallocated allowances for its retail loans by product type. The Bank’s retail loan portfolio is comprised of groups of large numbers of small value homogeneous loans. The Bank established an unallocated allowance for loans in each product group based on its estimate of the overall portfolio quality, asset growth, economic conditions and other risk factors. The Bank estimated its unallocated allowance for retail loans based on its probability of default and loss given default, determined for the respective risk pools.

Wholesale

Up to March 31, 2020, the allowance for wholesale loans consisted of specific and unallocated components. The allowance for such credit losses was evaluated on a regular basis by management and was based upon management’s view of the probability of recovery of loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, factors affecting the industry which the loan exposure relates to and prevailing economic conditions. This evaluation was inherently subjective as it required estimates that are susceptible to significant revision as more information became available.

Loans were charged off against the allowance when management believes that the loan balance may not be recovered. Subsequent recoveries, if any, against write-off cases were adjusted to provision for credit losses in the consolidated statement of income. The Bank grades its wholesale loan accounts considering both qualitative and quantitative criteria. Wholesale loans are considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, the financial condition of the borrower, the value of collateral held, and the probability of collecting scheduled principal and interest payments when due.

The Bank established specific allowances for each impaired wholesale loan customer, in the aggregate, for all facilities, including term loans, cash credits, bills discounted and lease finance, based on either the present value of expected future cash flows discounted at the loan’s effective interest rate or the net realizable value of the collateral if the loan is collateral dependent. Collateral values are generally based on appraisals from internal and external valuation sources. Wholesale loans that experienced insignificant payment delays and payment shortfalls were generally not classified as impaired but were placed on a surveillance watch list and closely monitored for deterioration. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, market information, and the amount of the shortfall in relation to the principal and interest owed. These factors were considered by the Bank for selection of loans for credit reviews and assessment of impairment.

The Bank also established an unallocated allowance for wholesale standard loans based on the internal rating grades assigned, and the probability of default associated with internal rating grade pools and the loss given default.

Effective April 1, 2020, the Bank adopted the CECL accounting guidance. The adoption of this guidance established a single allowance framework for all financial assets measured at amortized cost and certain off-balance sheet credit exposures including undrawn commitments not cancellable, Investments including AFS Securities and other financial assets measured at amortized cost. This framework requires that management’s estimate reflects credit losses over the instrument’s remaining expected life and considers expected future changes in macro-economic conditions.

The Bank’s allowance for credit losses comprises:

• the allowance for loan losses, which covers the Bank’s loan portfolios and is presented separately on the balance sheet in Loans,

• the allowance for lending-related commitments, which is recognized on the balance sheet in Accrued expenses and other liabilities,

• the allowance for credit losses on investment securities, which covers the Bank’s AFS debt securities and is recognized on the balance sheet in Investments available for sale debt securities on the balance sheet, and

• the allowance for credit losses on other financial assets measured at amortized cost, and other off-balance sheet credit exposures, which is recognized on the balance sheet in Accrued expenses and other liabilities.

All changes in the allowance for credit losses are recognized in the income statement.

Determining the appropriateness of the allowance for credit losses is complex and requires significant judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of credit exposures, considering the macro-economic conditions, forecasts and other factors then prevailing, may result in significant changes in the allowance for credit losses in future periods.

The Bank’s policies used to determine its allowance for credit losses and its allowance for lending-related commitments are described in the following paragraphs.

The Bank’s portfolio is bifurcated into Retail and Wholesale portfolios, wherein the Retail portfolio is segmented into homogenous pools using various factors such as nature of product, delinquencies, and other demographic and behavioral variables of the borrowers. The wholesale portfolio is segmented into various risk grades on the basis of a host of quantitative and qualitative factors including financial performance, industry risk, business risk and management quality. The allowance for loan-related losses and allowance for lending-related commitments represents expected credit losses over the remaining expected life of outstanding loans and lending-related commitments that are not unconditionally cancellable. The Bank does not record an allowance for future draws on unconditionally cancellable lending-related commitments (e.g., credit cards). The Bank does not record an allowance on accrued interest receivables on the balance sheet due to its policy to reverse interest income on loans more than 90 days past due and in the case of agricultural loans more than 365 days past due, and also on any loans classified as non-performing. The expected life for retail loans and wholesale loans is determined based on their contractual terms and expected prepayments. The expected life of funded credit card loans is generally estimated by considering expected future payments on the credit card account. The Bank has Unconditionally Cancellable Clauses (“UCC”) for credit card lines and as allowed by CECL accounting guidance, the Bank makes an allowance only for debt drawn at the time of expected loss measurement. The Bank applies expected principal payments to the credit card receivable balances existing at the reporting date until the balance is exhausted.

The estimate of expected credit losses includes expected recoveries of amounts previously charged off or expected to be charged off, even if such recoveries result in a negative allowance. The Retail loans are charged off against allowances typically when the account becomes 150 to 1,083 days past due depending on the type of loan. The defined delinquency levels at which major loan types are charged off are 150 days past due for personal loans and credit card receivables, 180 days for auto loans, commercial vehicle and construction equipment finance, 720 days past due for housing loans and on a customer by customer basis in respect of retail business banking when management believes that any future cash flows from these loans are remote including realization of collateral, if applicable, and where any restructuring or any other settlement arrangements were not feasible. The wholesale Loans are charged off against the allowance when management believes that the loan balance may not be recovered including realization of collateral, if applicable, and where any restructuring or any other settlement arrangements were not feasible. Subsequent recoveries, if any, against write-off cases are adjusted to provision for credit losses in the consolidated statement of income.

Wholesale loans are considered non-performing when, based on current information and events, it is probable that the Bank will be unable to collect scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining non-performance include payment status, the financial condition of the borrower, the value of collateral held, and the probability of collecting scheduled principal and interest payments when due. Wholesale loans that experienced insignificant payment delays and payment shortfalls are generally not classified as non-performing but are placed on a surveillance watch list and closely monitored for deterioration. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, market information, and the amount of the shortfall in relation to the principal and interest owed. These factors are considered by the Bank for selection of loans for credit reviews and assessment of allowance.

In order to estimate the allowance, the Bank primarily relies on its risk-segmentation models, which are also an integral part of the Bank’s risk management framework. Risk segmentation aims to group homogenous exposures together to allow for collective assessment of expected losses. Expected Loss estimation under collective assessment is primarily based on Probability of Default (“PD”), Loss given Default (“LGD”), and Exposure at Default (EAD) estimates. The Bank has modeled its PD estimates at the aforementioned granularity for its retail and wholesale portfolios and has also created the tenor structure of the same for computation of credit losses.

The Bank’s off-balance sheet credit exposures include unfunded loan commitments, financial guarantees, including standby letters of credit, and other similar instruments. For off-balance sheet credit exposures, the Bank recognizes an Allowance for credit loss (“ACL”) associated with the unfunded amounts. The Bank does not recognize an ACL for commitments that are unconditionally cancellable at the Bank’s discretion. ACL for off-balance sheet credit exposures are reported as a liability in accrued expenses and other liabilities on the consolidated balance sheet. ACL in such cases is measured for the remaining contractual term, adjusted for prepayments, of the financial asset (including off-balance sheet credit exposures) using historical experience, current conditions, and reasonable and supportable forecasts.

Collective and Individual Assessments

Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical loan default and loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information incorporate management’s view of current conditions and forecasts.

The methodology for estimating the amount of credit losses reported in the allowance for credit losses has two basic components: first, a pooled component for expected credit losses for pools of loans that share similar risk characteristics and second, an asset-specific component involving loans that do not share risk characteristics and the measurement of expected credit losses for such individual loans.

As an integral part of the credit process, the Bank has a credit rating model appropriate to its retail and wholesale credit segments. The Bank monitors credit quality within its segments based on primary credit quality indicators. This internal grading is updated at least annually. The majority of the Bank’s credit exposures share risk characteristics with other similar exposures, and as a result are collectively assessed for allowance (“portfolio-based component”). If an exposure does not share risk characteristics with other exposures, the Bank generally estimates expected credit losses on an individual basis, considering expected repayment and conditions impacting that individual exposure (“asset-specific component”). The asset-specific component covers loans modified or reasonably expected to be modified in a troubled debt restructuring (“TDR”), collateral-dependent loans, and borrowers with financial difficulties.

Portfolio-based component (Pooled Loans)

The portfolio-based component begins with a quantitative calculation that considers the likelihood of the borrower changing delinquency status or moving from one risk rating to another. The quantitative calculation covers expected credit losses over an instrument’s expected life and is estimated by applying credit loss factors to the Bank’s exposure at default.

Apart from its historical experience, the Bank seeks to incorporate any reasonable and supportable information regarding the prevalent and future economic and operating conditions, and their impact on credit losses for the Bank into its allowance. The Bank therefore includes in its estimation the use of quantitative statistical models to predict impact of macro-economic variables on defaults. The Bank relies on a single economic variable to develop reasonable and supportable forecasts. In deploying these models the Bank has assessed the impact of an exhaustive set of macro-economic variables such as GDP, inflation, Gross Capital Formation and Index of Industrial Production (“IIP”) on its expected losses, and uses consensus macro-economic forecasts surveyed and published by the Reserve Bank of India. As the consensus macro-economic forecasts are published for a year the Bank reverts to the historical average default rate beyond this period. Any adjustments needed to the modeled expected losses in the quantitative calculations are addressed through a qualitative adjustment. Such qualitative adjustment includes, among other things: the uncertainty of forward-looking scenarios based on the likelihood and severity of a possible recession; the uncertainty of economic conditions related to an alternative downside scenario; certain portfolio characteristics and concentrations; collateral coverage; model limitations; idiosyncratic events; and other relevant criteria. The qualitative adjustment also reflects the estimated impact of the COVID-19 pandemic on economic forecasts and credit loss estimates. The total ACL is comprised of the quantitative and qualitative components.

The Bank estimates its allowance for credit losses for pooled loans based on its probability of default and loss given default, determined for the respective risk pools.

Asset-specific component

To determine the asset-specific component of the allowance, collateral-dependent loans (including those loans for which foreclosure is probable) and larger and non-accrual risk-rated loans in the wholesale portfolio segment are generally evaluated individually, while smaller loans (both scored and risk-rated) are aggregated for evaluation based on factors relevant for the respective class of assets.

The Bank generally measures the asset-specific allowance as the difference between the amortized cost of the loan and the present value of the cash flows expected to be collected, discounted at the loan’s original effective interest rate. Subsequent changes in impairment, including those related to the passage of time, are generally recognized as an adjustment to the allowance for credit losses. For collateral-dependent loans, the fair value of collateral less estimated costs to sell is used to determine the charge-off amount for declines in value (to reduce the amortized cost of the loan to the fair value of collateral) or the amount of the negative allowance that should be recognized (for recoveries of prior charge-offs associated with improvements in the fair value of collateral).

The asset-specific component of the allowance for credit losses that have been or are expected to be modified in TDRs incorporates the effect of the modification on the loan’s expected cash flows (including forgone interest, principal forgiveness, and other concessions), and also the potential for redefault. For wholesale loans modified or expected to be modified in TDRs, expected losses incorporate management’s expectation of the borrower’s ability to repay under the modified terms.

Estimating the timing and amounts of future cash flows is highly subject to judgment as these cash flow projections rely upon estimates such as loss severities, asset valuations, default rates (including redefault rates on modified loans), the amounts and timing of interest or principal payments (including any expected prepayments) or other factors that are reflective of current and expected market conditions. All of these estimates and assumptions require significant management judgment and certain assumptions are highly subjective.

h. Income tax

The Bank estimates its income tax expense for the interim periods based on its best estimate of the expected effective income tax rate for a full year.

i. Revenue recognition

Interest income from loans and from investments is recognized on an accrual basis using the effective interest method when earned except in respect of loans or investments placed on non-accrual status, where it is recognized when received.

Fees and commissions from guarantees issued are amortized over the contractual period of the commitment.

Dividends from investments are recognized when declared.

Realized gains and losses on sale of securities are recorded on the trade date and are determined using the weighted average cost method.

Other fees and income are recognized when earned, which is when the service that results in the income has been provided. The Bank amortizes annual fees on credit cards over the contractual period of the fees.

j. Goodwill and other intangibles

Under applicable accounting guidance, goodwill is reviewed at the reporting unit level for potential impairment at least on an annual basis at the end of the reporting period, or more frequently if events or circumstances indicate a potential impairment. Up to March 31, 2020 this analysis was a two-step process. The first step of the goodwill impairment test compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, then the goodwill of the reporting unit was considered not impaired; however, if the carrying amount of the reporting unit exceeds its fair value, the second step is to be performed. The second step involved calculating an implied fair value of goodwill for each reporting unit for which the first step indicated possible impairment. On April 1, 2020, the Bank adopted ASU 2017-04 which eliminated the requirement to calculate the implied fair value of Goodwill (the second step). Accordingly, if the fair value of goodwill exceeds the goodwill assigned to the reporting unit, there is no impairment. If the goodwill assigned to a reporting unit exceeds the fair value of goodwill, an impairment charge is recorded for the excess. An impairment loss recognized cannot exceed the amount of goodwill assigned to a reporting unit, and the loss establishes a new basis for the goodwill. Consequently, a subsequent reversal of goodwill impairment losses is not permitted.

k. Recently adopted accounting standards

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes”. This ASU is part of the FASB’s initiative to make narrow-scope simplifications and improvements to accounting standards through a series of short-term projects. The ASU removes specific exceptions to general principles in Topic 740 (eliminating the need for an organization to analyze whether certain exceptions apply in a given period) and improving financial statement preparers’ application of certain income tax-related guidance. The amendments in the ASU are effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Bank adopted the ASU effective April 1, 2021. The adoption of this guidance did not have a material impact on the Bank’s consolidated financial position or results of operations.

In January 2020, the FASB issued ASU 2020-01, “Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815”. ASU 2016-01 made targeted improvements to accounting for financial instruments, including providing an entity with the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. The amendments in the ASU are effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Bank adopted the ASU effective April 1, 2021. The adoption of this guidance did not have a material impact on the Bank’s consolidated financial position or results of operations.

In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”. The ASU provides for optional expedients and other guidance related to modification of contracts, hedging relationships, and other transactions affected by reference rate reform. The ASU also provides an election to account for certain contract amendments related to reference rate reform as modifications rather than extinguishments without the requirement to assess the significance of the amendments. The various practical expedients and elections allow hedge accounting to continue uninterrupted during the transition period. The amendments in the update are elective and applicable on issue. The guidance terminates in December 2022. In January 2021, the FASB issued ASU No. 2021-01, Reference RateReform (Topic 848): Scope, which clarifies that the scope of the initial accounting relief issued by the FASB in March 2020 includes derivative instruments that do not reference a rate that is expected to be discontinued but that use an interest rate for margining, discounting or contract price alignment that is modified as a result of reference rate reform (commonly referred to as the “discounting transition”). The Bank adopted the ASU’s effective April 1, 2021. The adoption of this guidance did not have a material impact on the Bank’s consolidated financial position or results of operations.

l. Recently issued accounting pronouncements not yet effective

In August 2020, the FASB issued ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40)”. The ASU simplifies the accounting for convertible debt and convertible preferred stock by reducing the number of accounting models for these instruments, resulting in fewer embedded conversion features being separately recognized from the host contract. Additionally, this ASU revises the criteria for determining whether contracts in an entity’s own equity meet the scope exception from derivative accounting, which will change the population of contracts that are recognized as assets or liabilities. The amendments in this ASU also revise certain aspects of the guidance on calculating earnings per share with respect to convertible instruments and instruments that may be settled in the entity’s own shares. This ASU is effective for the Bank for interim and annual periods in fiscal years beginning after December 15, 2021. The Bank does not expect the adoption of ASU 2020-06 to have a material impact on its consolidated financial statements.

m. Convenience translation

The accompanying financial statements have been expressed in Indian Rupees (“Rs.”), the Bank’s functional currency. For the convenience of the reader, the financial statements as of and for the six-month period ended September 30, 2021 have been translated into U.S. dollars at US$1.00 = Rs. 74.16 as published by the Federal Reserve Board of New York on September 30, 2021. Such translation should not be construed as a representation that the rupee amounts have been or could be converted into U.S. dollars at that or any other rate, or at all.

2. Cash and due from banks, and restricted cash

The Bank is required to maintain a specific percentage of its demand and time liabilities by way of a balance in a current account with the RBI. This is to maintain the solvency of the banking system. As prescribed by the RBI, the cash reserve ratio has to be maintained on an average basis for a two-week period. The average balance maintained for such two-week period should not fall below the prescribed threshold limit. Non-maintenance of the requisite balance is subject to levy of penalty. The Bank has classified the cash reserve maintained with the RBI as restricted cash or restricted cash equivalents (restricted cash).

The cash and due from banks and restricted cash consist of restricted cash of Rs. 552,005.5 million and Rs. 542,004.8 million (US$ 7,308.6 million) as of March 31, 2021 and September 30, 2021, respectively.

3. Investments, held for trading

The portfolio of trading securities as of March 31, 2021 and September 30, 2021 was as follows:

	As of March 31, 2021
	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value
	(In millions)

As of September 30, 2021 there were 50 AFS investments in Government of India securities, State government securities and Government securities outside India with unrealized losses totaling Rs. 13,836.4 million. Upon analyzing the debt security portfolios, the Bank determined that no allowance was required as at September 30, 2021 in government issued or backed securities as for these debt securities the risk of loss was deemed minimal. Additionally, none of the remaining AFS investments in debt securities held by the Bank were past due or in non-accrual status as of September 30, 2021. The declines in the market value of these securities were attributable to changes in interest rates and not credit quality, and because the Bank had the ability and intent to hold these investments until there is a recovery in fair value, which may be at maturity, the Bank did not record any allowance for credit losses on any of these securities at September 30, 2021.

Credit Quality Indicators

The Bank monitors the credit quality of its investment securities through various risk management procedures, including the monitoring of credit ratings. A majority of the debt securities in the Bank’s investment portfolio were issued by the Government of India or State governments or entities or agencies that are either explicitly or implicitly guaranteed by such governments. The Bank believes the long history of no credit losses on these securities indicates that the expectation of non-payment of the amortized cost basis is zero, even if such governments were to technically default. Therefore, for the aforementioned securities, the Bank does not assess or record expected credit losses due to the zero loss assumption. The Bank monitors the credit quality of its remaining AFS investment portfolio which is updated periodically. Such of the remaining AFS investment portfolio in an unrealized loss position are evaluated to determine if the loss is attributable to credit-related factors and if an allowance for credit loss is needed. The average credit rating of the securities comprising the mortgage-backed securities and asset-backed securities was AAA (based upon external ratings where available) as at September 30, 2021.

The contractual residual maturity of available for sale debt securities other than asset and mortgage-backed securities as of September 30, 2021 is set out below:

For retail loans the policy and approval processes are designed for the fact that the Bank has high volumes of relatively homogeneous, small-value transactions in retail loans. There are product programs for each of these products, which define the target markets, credit philosophy and process, detailed underwriting criteria for evaluating individual credits, exception reporting systems and individual loan exposure caps. The quantitative parameters considered include income, residence stability and the nature of the employment/business, while the qualitative parameters include accessibility, contractibility and profile. The credit policies/product programs are based on a statistical analysis of the Bank’s experience and industry data, in combination with the judgment of the Bank’s senior officers. The Bank regularly mines data on its borrower account behavior as well as static data to monitor the portfolio performance of each product segment and uses these as inputs for revising the Bank’s product programs, target market definitions and credit assessment criteria to meet the Bank’s twin objectives of combining volume growth and maintenance of asset quality.

The Bank has in place a process of grading each borrower according to its financial health and the performance of its business and each borrower is graded as pass/labeled/non-performing. Wholesale loans that are not non-performing are disclosed as pass or labeled and considered to be performing. Labeled loans are those with evidence of weakness where such exposures indicate deteriorating trends which if not corrected could adversely impact repayment of the obligations. The Bank’s model assesses the overall risk over four major categories—industry risk, business risk, management risk and financial risk. The inputs in each of the categories are combined to provide an aggregate numerical rating, which is a function of the aggregate weighted scores based on the assessment under each of these four risk categories.

A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is dependent on the sale or operation of the underlying collateral. Such loans are carried at fair value based on current values determined by either independent appraisals or internal evaluations, adjusted for selling costs or other amounts to be deducted when estimating expected net sales proceeds. For the six-month period ended September 30, 2021, the Bank did not have collateral-dependent loans wherein the borrower is experiencing financial difficulty and the repayment of the loan is dependent on the sale of the underlying collateral.

Troubled debt restructuring (TDR)

When the Bank grants a concession for economic or legal reasons related to a borrower’s financial difficulties for other than an insignificant period of time, the related loan is classified as a TDR. Such concessions could include a reduction in the interest rate below current market rates, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. Loans, for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered TDRs. On restructuring, those loans are re-measured to reflect the impact, if any, on projected cash flows resulting from the modified terms. The impact of the TDR modifications and defaults are factored into the allowance for credit losses on a loan-by-loan basis. Modification may have little or no impact on the allowance established for the loan if there was no forgiveness of the principal and the interest was not decreased. A charge-off may be recorded at the time of restructuring if a portion of the loan is deemed to be uncollectable. A TDR classification can be removed if the borrower’s financial condition improves such that the borrower is no longer in financial difficulty, the loan has not had any forgiveness of principal or interest, and the loan is subsequently refinanced or restructured at market terms and qualifies as a new loan. There was no TDR modification during the fiscal year ended March 31, 2021 and the six-month period ended September 30, 2021.

Revenue Recognition

Deposit-related fees

Deposit-related fees consist of fees earned on consumer deposit activities and are generally recognized when the transaction occurs or as the service is performed. Consumer fees are earned on consumer deposit accounts for account maintenance and various transaction-based services, such as ATM transactions, wire transfer activities, check and money order processing, standing instruction processing, cash management services, etc.

Lending-related fees

Lending-related fees generally represent transactional fees earned from certain loan-related services, guarantees and letters of credit (“LCs”).

Third-party products-related fees

Third-party products-related fees consist of fees earned from distribution of third party products such as insurance and mutual funds.

Payments and cards business fees

Payments and cards business fees include fees earned from merchant acquiring business and on Credit, Debit, Prepaid or Forex cards, among others. Cards business income includes annual and renewal fees, late and over-limit fees, currency conversion fees, as well as fees earned from interchange, cash advances and other miscellaneous transactions fees. Interchange fees are recognized upon settlement of the credit and debit card payment transactions and are generally determined on a percentage basis for credit and debit cards based on the corresponding payment network’s rates. Substantially all cards business-related fees are recognized at the transaction date, except for certain time-based fees such as annual fees, which are recognized over 12 months.

13. Stock-based compensation

Assumptions used

The fair value of options has been estimated on the dates of each grant using a binomial option pricing model with the following assumptions:

	Six-month period ended September 30,
	2020		2021
Dividend yield		—	0.46%
Expected volatility		—	21.71%-31.79%
Risk-free interest rate		—	4.99%-6.43%
Expected term (in years)		—	2.59-5.36

The Bank recognizes compensation expense related to stock and option awards over the requisite service period, generally based on the instruments’ grant-date fair value, reduced by expected forfeitures. Ultimately, the compensation cost for all awards that vest is recognized.

14. Financial instruments

Foreign exchange and derivative contracts

The Bank enters into forward exchange contracts, currency options, forward rate agreements, currency swaps and rupee interest rate swaps with inter-bank participants on its own account and for customers. These transactions enable customers to transfer, modify or reduce their foreign exchange and interest rate risks.

Forward exchange contracts are commitments to buy or sell foreign currency at a future date at the contracted rate. Currency swaps are commitments to exchange cash flows by way of interest in one currency against another currency and exchange of principal amount at maturity based on predetermined rates. Interest rate swaps are commitments to exchange fixed and floating rate interest cash flows. A forward rate agreement gives the buyer the ability to determine the underlying rate of interest for a specified period commencing on a specified future date (the settlement date) when the settlement amount is determined being the difference between the contracted rate and the market rate on the settlement date. Currency options give the buyer the right, but not an obligation, to buy or sell specified amounts of currency at agreed rates of exchange on or before a specified future date.

The market and credit risks associated with these products, as well as the operating risks, are similar to those relating to other types of financial instruments. Market risk is the exposure created by movements in interest rates and exchange rates during the tenure of the transaction. The extent of market risk affecting such transactions depends on the type and nature of the transaction, the value of the transaction and the extent to which the transaction is uncovered. Credit risk is the exposure to loss in the event of default by counterparties. The extent of loss on account of a counterparty default will depend on the replacement value of the contract at the ongoing market rates.

The Bank uses its pricing models to determine fair values of its derivative financial instruments. The Bank records credit risk valuation adjustments on derivative financial instruments in order to reflect the credit quality of the counterparties and its own credit quality. The Bank calculates valuation adjustments on derivatives based on observable market credit risk spreads.

The following table presents the aggregate notional principal amounts of the Bank’s outstanding forward exchange and other derivative contracts as of March 31, 2021 and September 30, 2021, together with the fair values on each reporting date.

Offsetting

The following table shows the impact of netting arrangements on derivative financial instruments, repurchase and reverse repurchase agreements that are subject to enforceable master netting arrangements or similar agreements, but are not offset in accordance with ASC 210-20-45 and ASC 815-10-45.

The Bank enters into International Swaps and Derivatives Association, Inc. (“ISDA”) master netting agreements or similar agreements with substantially all of the Bank’s foreign exchange and derivative contract counterparties. These master netting agreements give the Bank, in the event of default by the counterparty, the right to liquidate collaterals held or placed and to offset receivables and payables with the same counterparty. In the table below the Bank has presented the gross derivative assets and liabilities adjusted for the effects of master netting agreements and collaterals received or pledged.

Transactions with counterparties for Securities sold under agreements to repurchase (“repos”) and Securities purchased under agreements to resell (“reverse repos”) are settled through the Clearing Corporation of India Limited (“CCIL”), a centralized clearing house. Collaterals received or pledged are comprised of highly liquid investments. For undertaking the above transactions, power of attorney is executed by the Bank and the counterparties in favor of CCIL to liquidate the securities pledged in the event of default.

Guarantees

As a part of its commercial banking activities, the Bank has issued guarantees and documentary credits, such as letters of credit, to enhance the credit standing of its customers. These generally represent irrevocable assurances that the Bank will make payments in the event that the customer fails to fulfill its financial or performance obligations. Financial guarantees are obligations to pay a third-party beneficiary where a customer fails to make payment towards a specified financial obligation. Performance guarantees are obligations to pay a third-party beneficiary where a customer fails to perform a non-financial contractual obligation. The tenure of the guarantees issued or renewed by the Bank is normally in line with requirements on a case-by-case basis as may be assessed by the Bank. The remaining tenure of guarantees currently issued by the Bank and outstanding ranges from 1 day to 24.1 years.

The credit risk associated with these products, as well as the operating risks, is similar to those relating to other types of financial instruments.

In accordance with FASB ASC 460-10 the Bank has recognized a liability of Rs. 5,500.7 million as of March 31, 2021 and of Rs. 5,165.5 million as at September 30, 2021, in respect of guarantees issued or modified.

As part of its risk management activities, the Bank continuously monitors the creditworthiness of customers as well as guarantee exposures. If a customer fails to perform a specified obligation, a beneficiary may draw upon the guarantee by presenting documents in compliance with the guarantee. In that event, the Bank makes payment on account of the defaulting customer to the beneficiary up to the full notional amount of the guarantee. The customer is obligated to reimburse the Bank for any such payment. If the customer fails to pay, the Bank liquidates any collateral held and sets off accounts; if insufficient collateral is held, the Bank recognizes a loss. Margins in the form of cash and fixed deposit available to the Bank to reimburse losses realized under guarantees amounted to Rs. 121.2 billion and Rs. 153.1 billion as of March 31, 2021 and September 30, 2021, respectively. Other property or security may also be available to the Bank to cover losses under these guarantees.

Undrawn commitments

The Bank has outstanding undrawn commitments to provide loans and financing to customers. These commitments aggregated to Rs. 628.3 billion and Rs. 623.1 billion (US$ 8.4 billion) as of March 31, 2021 and September 30, 2021, respectively. Among other things, the making of a loan is subject to a review of the creditworthiness of the customer at the time the customer seeks to borrow, at which time the Bank has the unilateral right to decline to make the loan. If the Bank were to make such loans, the interest rates would be dependent on the lending rates in effect when the loans were disbursed. Further, the Bank has unconditional cancellable commitments aggregating to Rs. 4,826.7 billion and Rs. 5,043.1 billion (US$ 68.0 billion) as of March 31, 2021 and September 30, 2021, respectively.

The allowance for credit losses included in accrued expenses and other liabilities on off-balance sheet credit exposures and undrawn commitments is as follows:

	March 31, 2021		September 30, 2021		September 30, 2021

15. Estimated fair value of financial instruments

The Bank’s financial instruments include financial assets and liabilities recorded on the balance sheet, including instruments such as foreign exchange and derivative contracts. Management uses its best judgment in estimating the fair value of the Bank’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of all the amounts the Bank could have realized in a sales transaction as of March 31, 2021 and September 30, 2021, respectively. The estimated fair value amounts as of March 31, 2021 and September 30, 2021 have been measured as of the respective year ends, and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each year end.

16. Segment information

The Bank operates in three reportable segments: wholesale banking, retail banking and treasury services. The revenue and related expense recognition policies are set out in note 1. Substantially all operations and assets are based in India.

The retail banking segment serves retail customers through a branch network and other delivery channels. This segment raises deposits from customers and grant loans, provides credit cards and debit cards, and distributes third-party financial products, such as mutual funds and insurance to such customers. Revenues of the retail banking segment are derived from interest earned on retail loans, fees for banking services, profit from foreign exchange and derivative transactions and interest earned from other segments for surplus funds placed with those segments. Expenses of this segment are primarily comprised of interest expense on deposits, infrastructure and premises expenses for operating the branch network and other delivery channels, personnel costs, other direct overheads and allocated expenses. The Bank’s retail banking loan products also include loans to small and medium enterprises for commercial vehicles, construction equipment and other business purposes. Such grouping ensures optimum utilization and deployment of specialized resources in the retail banking business.

The wholesale banking segment provides loans and transaction services to corporate customers. As discussed above, loans to small and medium enterprises for commercial vehicles, construction equipment and other business purposes are included in the retail banking segment. Revenues of the wholesale banking segment consist of interest earned on loans given to corporate customers, investment income from credit substitutes, interest earned on the cash float arising from transaction services, fees from such transaction services and profits from foreign exchange and derivative transactions with wholesale banking customers. The principal expenses of the segment consist of interest expense on funds borrowed from other segments, premises expenses, personnel costs, other direct overheads and allocated expenses.

The treasury services segment undertakes trading operations on proprietary account (including investments in government securities), foreign exchange operations and derivatives trading both on proprietary account and customer flows and borrowings. Revenues of the treasury services segment primarily consist of fees and gains and losses from trading operations and of net interest revenue/expense from investments in government securities and borrowings. Revenues from foreign exchange and derivative operations and customer flows are classified under the retail or wholesale segments depending on the profile of the customer.

Segment income and expenses include certain allocations. Interest income is charged by a segment that provides funding to another segment, based on yields benchmarked to an internally developed composite yield curve which broadly tracks market-discovered interest rates.

Directly identifiable overheads are attributed to a segment at actual amounts incurred. Indirect shared costs, principally corporate office expenses, are generally allocated to each segment on the basis of area occupied, number of staff, volume and nature of transactions. The wholesale banking segment includes unallocated tax balances and other items.

17. Commitments and contingencies

Commitments and contingent liabilities other than for off-balance sheet financial instruments (see note 14) are as follows:

Capital commitments

The Bank has entered into committed capital contracts, principally for branch expansion and technology upgrades. The estimated amounts of contracts remaining to be executed on the capital account as of March 31, 2021 and September 30, 2021 aggregated Rs. 12,895.7 million and Rs. 20,354.9 million, respectively.

Contingencies

The Bank is party to various legal proceedings in the normal course of business. The Bank estimates the provision for contingencies which primarily include indirect taxes since no precedents exist which could be used as points of reference. The amount of claims against the Bank towards indirect taxes and other claims which are not acknowledged as debts as at March 31, 2021 and September 30, 2021 amounted to Rs. 10,203.1 million and Rs. 10,191.5 million, respectively. The Bank does not expect the outcome of these proceedings to have a material adverse effect on the Bank’s results of operations, financial condition or cash flows. The Bank intends to vigorously defend these claims. Although the results of other legal actions cannot be predicted with certainty, it is the opinion of management, after taking appropriate legal advice, that the likelihood of these claims becoming obligations of the Bank is remote and hence the resolution of these actions will not have a material adverse effect, if any, on the Bank’s business, financial condition or results of operations.

Lease commitments

The Bank is party to operating leases for certain of its office premises and employee residences, with a renewal at the option of the Bank. Operating lease right-of-use assets and lease liabilities were as follows:

	As of
	March 31, 2021		September 30, 2021		September 30, 2021
	(In millions)
Right-of-use assets	Rs.	64,548.8		Rs.68,208.8	US$	919.8
Lease liabilities		70,422.0		74,347.2		1,002.5

The total lease expenses were as follows:

	Six-month period ended September 30,
	2020		2021		2021
	(In millions)
The total minimum lease expense during the period recognized in the consolidated statement of income	Rs.	6,774.4		Rs.7,357.2	US$	99.2

The total operating cash flow for operating lease expenses for the six-month period ended September 30, 2020 and September 30, 2021 was Rs. 6,394.5 million and Rs. 6,666.2 million (US$ 89.9 million), respectively.

Weighted average discount rate		7.0	%		7.0	%

The Bank adopted ASU 2016-02 “Leases (Topic 842)” and subsequent related updates on April 1, 2019. The Bank enters into lease agreements to obtain the right-of-use assets for its business operations, substantially all of which are premises. Lease liabilities and right-of-use assets are recognized when the Bank enters into operating leases and represent obligations and rights to use these assets over the period of the leases and are re-measured for modifications. Operating lease liabilities include fixed payments for the contractual duration of the lease, adjusted for renewals or terminations. The lease agreements entered into by the Bank do not include any material residual value guarantees and material restrictive covenants. The lease payments are discounted using a rate determined when the lease is recognized. In general, the Bank does not know the discount rate implicit in the lease, and so the Bank estimates a discount rate that the Bank believes approximates a collateralized borrowing rate for the estimated duration of the lease term. The rate is determined at the date of commencement of the lease and for leases existing as at April 1, 2019; the incremental borrowing rate is determined as at that date. At lease commencement, lease liabilities are recognized based on the present value of the remaining lease payments and discounted using the incremental borrowing rate. Right-of-use assets are reported in other assets on the consolidated balance sheet and related lease liabilities are reported in accrued expenses and other liabilities. The amortization of operating lease right-of-use assets and the accretion of operating lease liabilities are reported together as fixed lease expenses and are included in non-interest expense premises and equipment. The lease expense is recognized on a straight-line basis over the life of the lease. The lease agreements entered into by the Bank generally have renewal and escalation clauses. These agreements also in general permit the Bank to terminate the lease arrangement within a certain period of notice of termination. The Bank does not include renewal or termination options in the establishment of the lease term when it is not reasonably certain that it will exercise them. The Bank has elected to exclude leases with terms of less than one year from the operating lease right-of-use assets and lease liabilities. The related short-term lease expense is included in non-interest expense premises and equipment. The Bank accounted for lease-related concessions obtained as a result of the COVID-19 pandemic in accordance with guidance in Topic 842. As of September 30, 2021, the Bank had additional undiscounted operating lease commitments of Rs. 107.3 million, predominantly for premises with leases which have not yet commenced. These leases will commence by October 2021 and have lease terms of 9 years.

18. Earnings per equity share

By way of an ordinary resolution passed on July 12, 2019, the shareholders of the Bank approved a subdivision (stock split) of equity shares to reduce the face value of each equity share from Rs. 2.0 to Rs. 1.0 per equity share effective as of September 20, 2019. The number of issued and subscribed equity shares increased to 5,470,763,894 shares of par value Rs. 1.0 each. All share/ADS and per share/ADS data reflect the effect of the stock split retroactively. One ADS continues to represent three equity shares.

A reconciliation of the equity shares used in the computation of basic and diluted earnings per equity share has been provided below. Potential equity shares in the nature of Employees Stock Option Scheme (“ESOP”) with average outstanding balance of 81,084,827 million and 12,764,673 million were excluded from the calculation of diluted earnings per share for the six-month periods ended September 30, 2020 and September 30, 2021, respectively, as these were anti-dilutive.

19. Fair value measurement

FASB Accounting Standards Codification (“ASC”) 820 (Topic 820) Fair Value Measures and Disclosures defines fair value, establishes a framework for measuring fair value in US GAAP, and expands disclosures about fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

Level of input
Level 1	Unadjusted quoted market prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities.
Level 2	Quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3	Inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).

The following is a description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. These valuation methodologies were applied to all of the Bank’s financial assets and financial liabilities carried at fair value. For Level 1 instruments the valuation is based upon the unadjusted quoted prices of identical instruments traded in active markets. For Level 2 instruments, where such quoted market prices are not available, the valuation is based upon the quoted prices for similar instruments in active markets, the quoted prices for identical or similar instruments in markets that are not active, prices quoted by market participants and prices derived from standard valuation methodologies or internally developed models that primarily use, as inputs, such as interest rates, yield curves, volatilities and credit spreads, which are available from public sources such as Reuters, Bloomberg and the Fixed Income Money Markets and Derivatives Association of India. The valuation methodology primarily includes discounted cash flow techniques. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Bank’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The valuation of Level 3 instruments is based on valuation techniques or models which use significant market unobservable inputs or assumptions.

The Bank uses its quantitative pricing models to determine the fair value of its derivative instruments. These models use multiple market inputs including interest rates, prices and indices to generate continuous yield or pricing curves and volatility factors to value the positions that are observable directly or indirectly. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Bank’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time.

Financial assets and financial liabilities measured at fair value on a recurring basis:

Available for sale debt securities: Available for sale debt securities are carried at fair value. Such fair values were based on quoted market prices, if available. If quoted market prices did not exist, fair values were estimated using the market yield on the balance period to maturity on similar instruments and similar credit risks. The fair value of asset-backed and mortgage-backed securities is estimated based on revised estimated cash flows at each balance sheet date, discounted at current market pricing for transactions with similar risk. A reduction in the estimated cash flows of these instruments will adversely impact the value of these securities. A change in the timing of these estimated cash flows will also impact the value of these securities.

Trading securities: Trading securities are carried at fair value based on quoted market prices or market observable inputs.

Held to maturity securities: There were no HTM securities as of March 31, 2021 and September 30, 2021.

20. Risk and uncertainties

a) The outbreak of the COVID-19 pandemic had led to a nation-wide lockdown in April-May 2020. This was followed by local lockdowns in areas with a significant number of COVID-19 cases. Following the easing of lockdown measures, there was an improvement in economic activity in the second half of fiscal year 2021. India experienced a “second wave” of the COVID-19 pandemic in April-May 2021 following the discovery of mutant coronavirus variants, leading to the re-imposition of regional lockdowns. These were gradually lifted as the second wave subsided. By December 2021, another variant “Omicron” started spreading in India. However, with improved vaccination rates, the impact of the variant was lower than that of previous waves. Moving forward, there continues to be significant uncertainty relating to the further progression of other waves. The impact of COVID-19, including changes in customer behavior and pandemic fears, as well as restrictions on business and individual activities, has led to significant volatility in global and Indian financial markets and a significant decrease in global and local economic activities. The disruptions following the outbreak have impacted loan originations, the sale of third-party products, the use of credit and debit cards by customers and the efficiency in collection efforts resulting in an increase in customer defaults and consequently an increase in provisions there against. India is emerging from the COVID-19 pandemic. The extent to which the COVID-19 pandemic will continue to impact the Bank’s results will depend on ongoing as well as future developments, which are uncertain, including, among other things, any new information concerning the severity of the COVID-19 pandemic, and any action to contain its spread or mitigate its impact whether government-mandated or elected by us.

b) On September 3, 2020, a securities class action lawsuit was filed against the Bank and certain of its current and former directors in the United States District Court for the Eastern District of New York (the “Court”) . The complaint was amended on February 8, 2021. The amended complaint alleges that the Bank, its former managing director, Mr. Aditya Puri, and the present managing director and CEO, Mr. Sashidhar Jagdishan made materially false and misleading statements regarding certain aspects of the Bank’s business and compliance policies, which the complaint alleges resulted in the Bank’s ADS price declining on July 13, 2020, thereby allegedly causing damage to the Bank’s investors. The Bank’s motion to dismiss the suit was filed on April 9, 2021, to which the lead plaintiff served its brief in opposition on June 8, 2021. The Bank, on July 23, 2021, through its legal counsel, has filed the reply memorandum of law in further support of the motion to dismiss the securities class action suit. The Bank’s motion to dismiss remains pending before the Court. Given the uncertainty inherent in these matters, and based on an assessment made after taking appropriate legal advice, at this point in time, the Bank does not believe that the ultimate outcome of this matter will be materially unfavorable to the Bank. Accordingly, no liability has been recorded in the Bank’s consolidated financial statements. The Bank intends to continue to vigorously defend against the allegations.

c) The ongoing war between Russia and Ukraine complicates the geopolitical landscape. The United States, the United Kingdom and the European Union have expanded sanctions significantly against Russia which could impact global markets and thus the Bank and its customers. The Bank continues to monitor developments and seeks to manage the associated impacts on its customers and business.

21. Subsequent events

a) In its meeting held on April 4, 2022, the of the Board of Directors of the Bank approved a composite scheme of amalgamation (the “Scheme”) for the amalgamation of: (i) HDFC Investments Limited and HDFC Holdings Limited, each a subsidiary of HDFC Limited, with and into HDFC Limited, and (ii) HDFC Limited with and into HDFC Bank (the “Proposed Transaction”). The share exchange ratio shall be 42 equity shares of HDFC Bank (each having a face value of Rs. 1) for every 25 equity shares of HDFC Limited (each having a face value of Rs. 2).

The completion of the Scheme and the Proposed Transaction is subject to customary closing conditions, including the receipt of requisite approvals from the RBI, the Competition Commission of India, the National Housing Bank, the Insurance Regulatory and Development Authority of India, the Pension Fund Regulatory and Development Authority, the National Company Law Tribunal, the Securities Exchange Board of India, BSE Limited, the National Stock Exchange of India Limited and other statutory and regulatory authorities, and the respective shareholders and creditors, under applicable Indian law. It is currently anticipated that the Proposed Transaction will be completed during fiscal year 2024. While HDFC Bank has received certain approvals and no objection letters in regard to the Proposed Transaction subject to certain conditions, further approvals and letters will be required in due course. There can be no assurance that the remaining closing conditions will be satisfied in a timely manner or at all, or that an effect, event, development or change will not transpire that could delay or prevent these conditions from being satisfied.

Upon the Scheme becoming effective and following RBI’s permission if received for relaxation of certain regulatory requirements for subsidiaries of HDFC Bank (for which forbearance application was filed on March 28, 2022), the subsidiaries of HDFC Limited will become subsidiaries of HDFC Bank leading to a simplified corporate structure. In addition, upon the Scheme becoming effective, the Bank will issue equity shares to the shareholders of HDFC Limited as on the record date, which is to be determined by the Boards of Directors of HDFC Limited and HDFC Bank, and the equity shares held by HDFC Limited in the Bank will be extinguished. The shares proposed to be issued pursuant to the Proposed Transaction will not be registered with the SEC under the Securities Act of 1933 or the securities law of any state or other jurisdiction of the United States, and are being offered and sold in reliance on certain exemptions from registration under the Securities Act.

b) In its meeting held on April 23, 2022, the Board of Directors of the Bank recommended a dividend of Rs. 15.50 per share, which has been subsequently approved by the shareholders for payment in their Annual General Meeting, held on July 16, 2022. The amount of such dividend aggregated to Rs. 86,045.2 million.
