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 income taxes, stock-based compensation, employee benefits, loan origination fees, derivative financial instruments, business combination and the presentation format and disclosures of the financial statements and related notes. The condensed consolidated balance sheet at March 31, 2014 has been derived from the Bank’s audited consolidated financial statement at that date. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included.

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 periods presented. Actual results could differ from these estimates. Material estimates included in these financial statements that are susceptible to change include the allowance for credit losses, the valuation of unquoted investments, other than temporary impairment, valuation of derivatives, stock-based compensation and impairment assessment of goodwill.

d. 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.

Retail

The Bank’s retail loan loss allowance consists of specific and unallocated allowances.

The Bank establishes 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 monitors loan to value ratios for loan against securities. The 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 past due 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 are not feasible.

The Bank also records 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 establishes 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 estimates its unallocated allowance for retail loans based on an internal credit slippage matrix, which measures the Bank’s historic losses for its standard loan portfolio. Subsequent recoveries, if any, against write-off cases, are adjusted to provision for credit losses in the consolidated statement of income.

Wholesale

The allowance for wholesale loans consists of specific and unallocated components. The allowance for such credit losses is evaluated on a regular basis by management and is 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 is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Loans are charged off against the allowance when management believes that the loan balance cannot be recovered. Subsequent recoveries, if any, against write-off cases, are 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 establishes 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.

Wholesale loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired 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.

In light of the significant growth in the size and diversity of its wholesale loan portfolio, the Bank has also established an unallocated allowance for wholesale standard loans based on the overall portfolio quality, asset growth, economic conditions and other risk factors. The Bank estimates its wholesale unallocated allowance based on an internal credit slippage matrix, which measures the Bank’s historic losses for its standard loan portfolio.

e. 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.

f. Revenue recognition

Interest income from loans and from investments is recognized on an accrual basis using effective interest method when earned except in respect of loans or investments placed on non-accrual status, where it is recognized when received. Nominal loan application fees are charged which offset the related costs incurred.

Fees and commissions from guarantees issued are amortized over the contractual period of the commitment, provided the amounts are collectible.

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.

g. Recently adopted accounting standards

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). As per the amendment, an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss (NOL) or other tax credit carry forward when settlement in this manner is available under the tax law. The assessment of whether settlement is available under the tax law would not consider future events (e.g., upcoming expiration of related NOL carry forwards). This classification should not affect an entity’s analysis of the realization of its deferred tax assets. Gross presentation in the rollforward of unrecognized tax positions in the notes to the financial statements would still be required. ASU 2013-11 is effective for interim and annual periods beginning on or after December 15, 2013. The adoption of this guidance effective April 1, 2014 did not have a material impact on the Bank’s consolidated financial position or results of operations.

h. Recently issued accounting pronouncements not yet effective

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This update clarifies the principles for revenue recognition in transactions involving contracts with customers. The guidance will be effective for the interim and annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Bank has not yet evaluated what impact, if any, the adoption of this guidance may have on the Bank’s financial condition, results of operations, or disclosures.

In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860)”. The amendments in this update change the current accounting outcome by requiring repurchase-to-maturity transactions to be accounted for as secured borrowings and for repurchase financing arrangement the amendments require separate accounting for a transfer of the financial asset executed contemporaneously with a repurchase agreement with same counterparty. The amendments also require new disclosures. The guidance will be effective for the interim and annual reporting periods beginning after December 15, 2014 and early adoption is not permitted. The Bank has not yet evaluated what impact, if any, the adoption of this guidance may have on the Bank’s financial condition, results of operations, or disclosures.

In August 2014, the FASB also issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU requires management to perform an assessment of going concern and provides specific guidance on when and how to assess or disclose going concern uncertainties. The new standard also defines terms used in the evaluation of going concern, such as “substantial doubt.” Following application, the Bank will be required to perform assessments at each annual and interim period, provide an assessment period of one year from the issuance date, and make disclosures in certain circumstances in which substantial doubt is identified. The amendment will be effective for the Bank for the first reporting period ending after December 15, 2016. Earlier application is permitted. The Bank does not expect this ASU to have an impact on its financial position, result of operations, or disclosures.

AFS investments of Rs. 820,565.8 million and Rs. 996,147.8 million (US$ 16,087.7 million) as of March 31, 2014 and September 30, 2014, respectively, are eligible for placement towards the Bank’s statutory liquidity ratio requirements. These balances are subject to withdrawal and usage restrictions, but may be freely traded by the Bank within those restrictions. Of these investments, Rs. 670,603.5 million as of March 31, 2014 and Rs. 730,463.5 million (US$ 11,796.9 million) as of September 30, 2014, respectively, were kept as margins for clearing, collateral borrowing and lending obligation (CBLO), real time gross settlement (RTGS), with the Reserve Bank of India and other financial institutions.

The Bank conducts a review each reporting period to identify and evaluate investments that have indications of possible impairment. An investment in an equity or debt security is impaired if its fair value falls below its cost and the decline is considered other than temporary. Factors considered in determining whether a loss is temporary include length of time and extent to which fair value has been below cost, the financial condition and near-term prospects of the issuer and whether the Bank intends to sell or will be required to sell the security until the forecasted recovery. The Bank evaluated the impaired investments and has fully recognized an expense of Nil and Rs.1.8 million as other than temporary impairment for six months periods ended September 30, 2013 and September 30, 2014, respectively, because the Bank intends to sell the securities before recovery of their amortized cost. The Bank is of the opinion that the other unrealized losses on its investments in equity and debt securities as of September 30, 2014 are temporary in nature. The Bank’s review of impairment generally entails:

• identification and evaluation of investments that have indications of possible impairment;

• analysis of individual investments that have fair values of less than 95% of amortized cost, including consideration of the length of time the investment has been in an unrealized loss position;

• 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 analysis, as required under business policies.

As of March 31, 2014 and September 30, 2014, the Bank did not hold any debt securities with credit losses for which a portion of other-than-temporary impairment was recognized in other comprehensive income.

The Bank has a credit risk mitigating/monitoring mechanism which is comprised of target market definitions, credit approval process, post-disbursement monitoring and remedial management procedures.

For wholesale credit risk in addition to the credit approval process the Bank has an approved framework for the review and approval of credit ratings. Credit Policies and Procedures articulate credit risk strategy and thereby the approach for credit origination, approval and maintenance. The Credit Policies generally address such areas as target markets, portfolio mix, prudential exposure ceilings, concentration limits, price and non-price terms, structure of limits, approval authorities, exception reporting system, prudential accounting and provisioning norms. These are reviewed in detail at annual or more frequent intervals. To ensure adequate diversification of risk, concentration limits have been set up in terms of borrower/business group, industry and risk grading.

For retail credit 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, 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 our own experience and industry data, in combination with the judgment of our senior officers. The Bank mines data on our borrower account behavior as well as static data regularly to monitor the portfolio performance of each product segment and use these as inputs in revising our product programs, target market definitions and credit assessment criteria to meet our twin objectives of combining volume growth and maintenance of asset quality.

As an integral part of the credit process, the Bank has a credit rating model appropriate to its wholesale and retail credit segments (see note 1d). The Bank monitors credit quality within its segments based on primary credit quality indicators. This internal grading is updated atleast annually.

Wholesale Loans

We have 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/impaired. Our 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.

Troubled debt restructuring (TDR)

When the Bank grants 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. 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, the loans are re-measured to reflect the impact, if any, on projected cash flows resulting from the modified terms. 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 uncollectible.

The following table summarizes our TDR modifications during the year ended March 31, 2014 and six months period ended September 30, 2014 presented by primary modification type and includes the financial effects of these modifications.

Branch network intangible represents the benefit that the Bank received through the acquisition of a ready branch network from Centurion Bank of Punjab Limited (“CBoP”) as opposed to having to build a new one. The fair value attributable to the branch network intangible is the difference in the present values of the earnings (net of costs) that the Bank would have generated if the Bank had set up its own branches/ATMs (the “Hypothetical New Branch Network Earnings”) and the earnings (net of costs) that were generated because of the acquisition of CBoP (the “CBoP Branch Network Earnings”). Similar streams of revenues and operating costs (and therefore profits) from CBoP’s existing customer base and loan portfolio (includes net interest income, fees and commission) have been considered in determining the values of the Hypothetical New Branch Network Earnings and the CBoP Branch Network Earnings. Other assets including intangibles such as customer list, core deposits, loans, premises and equipment have been considered as assets of Hypothetical New Branch Network Earnings and the CBoP Branch Network Earnings and the value of these assets have been included in both of the networks. The aforesaid present values to compute the said intangible assets was intended to capture the advantages that the Bank received through the acquisition of a ready branch network from CBoP (as opposed to having to build a new one) in terms of time and of avoiding the administrative process required to obtaining branch licenses from the RBI. The Bank calculated the value of the customer list intangible through the cost approach by considering the estimated direct unit costs to source these customers multiplied by the number of customers. The Bank used the cost savings approach, i.e. the difference between the estimated cost of funds on deposit (interest cost and net maintenance costs) and the estimated cost of an equal amount of funds from an alternative source to calculate the core deposit intangible. The valuation of favorable leases intangibles was based on the cost saving to the Bank and future economic benefit until the lease expiry.

11. 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. Rupee interest rate swaps are commitments to exchange fixed and floating rate cash flows in rupees. 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 risk 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, 2014 and September 30, 2014, 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 we have 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 comprise 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 his 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 case by case basis as may be assessed by the Bank. The remaining tenure of guarantees presently issued by the Bank and outstanding range from 1 day to 18.4 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.

Total	Rs.	(1,480.7	)	Rs.	(1,605.4	)	US$	(25.9	)

As part of its risk management activities, the Bank continuously monitors the credit-worthiness 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.

Loan sanction letters

The Bank issues sanction letters indicating its intent to provide new loans to certain customers. The aggregate of loans contemplated in these letters that had not yet been disbursed was Rs. 616,957.6 million as of September 30, 2014. 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. The Bank has no commitment to lend under these letters. Among other things, the making of a loan is subject to a review of the credit-worthiness 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.

12. 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, 2014 and September 30, 2014. The estimated fair value amounts as of March 31, 2014 and September 30, 2014 have been measured as of the respective period end, 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 period end.

Financial instruments valued at carrying value

        The respective carrying values of certain on-balance-sheet financial instruments approximated their fair value. These financial instruments include cash and amounts due from banks, interest-bearing deposits in banks, securities purchased and sold under resale and repurchase agreements, accrued interest receivable, acceptances, accrued interest payable, and certain other assets and liabilities that are considered financial instruments. Carrying values were assumed to approximate fair values for these financial instruments as they are short-term in nature and their recorded amounts approximate fair values or are receivable or payable on demand.

Trading securities

Trading securities are carried at fair value based on quoted market prices. If quoted market prices did not exist, fair values were estimated using market yield on balance period to maturity on similar instruments and similar credit risk. For more information on the fair value of these securities, refer to Note 2.

Available for sale securities

Available for sale investments principally comprise of debt securities and 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 a market yield on the balance period to maturity on similar instruments and similar credit risks. The fair values of asset-backed and mortgage-backed securities are estimated based on revised estimated cash flows at each balance sheet date, discounted at current market pricing for transactions with similar risk. For more information on the fair value of these securities, refer to Note 3.

Loans

The fair values of consumer installment loans and other consumer loans that do not reprice frequently were estimated using discounted cash flow models. The discount rates were based on current market pricing for loans with similar characteristics and risk factors. Since, substantially all individual lines of credit and other variable rate consumer loans reprice frequently, with interest rates reflecting current market pricing, the carrying values of these loans approximate their fair values.

The fair values of commercial loans that do not reprice or mature within relatively short time frames were estimated using discounted cash flow models. The discount rates were based on current market interest rates for loans with similar remaining maturities and credit ratings. For commercial loans that reprice within relatively short time frames, the carrying values approximate their fair values.

For purposes of these fair value estimates, the fair values of impaired loans were computed by deducting an estimated market discount from their carrying values to reflect the uncertainty of future cash flows.

Deposits

The fair value of demand deposits, savings deposits, and money market deposits without defined maturities are the amounts payable on demand. For deposits with defined maturities, the fair values were estimated using discounted cash flow models that apply market interest rates corresponding to similar deposits and timing of maturities.

Short-term borrowings

The fair values of the Bank’s short-term debt were calculated based on a discounted cash flow model. The discount rates were based on yield curves appropriate for the remaining maturities of the instruments.

Long-term debt

The fair values of the Bank’s unquoted long-term debt instruments were calculated based on a discounted cash flow model. The discount rates were based on yield curves appropriate for the remaining maturities of the instruments.

13. 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 makes loans, provides credit cards and debit cards, distributes third-party financial products, such as mutual funds and insurance, and provides advisory services to such customers. Revenues of the retail banking segment are derived from interest earned on retail loans, fees for banking and advisory 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 made 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 the proprietary account (including investments in government securities), foreign exchange operations and derivatives trading both on the 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. Wholesale banking segment includes unallocated tax balances and other items.

14. Commitments and contingencies

Commitments and contingent liabilities other than for off balance sheet financial instruments (see note 11) 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, 2014 and September 30, 2014 aggregated Rs. 2,492.2 million and Rs. 2,719.5 million, respectively.

Contingencies

The Bank is party to various legal proceedings in the normal course of business. The Bank estimates the provision for 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 of March 31, 2014 and September 30, 2014 aggregated to Rs. 4,090.9 million and Rs.4,215.6 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 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, employee residences and ATMs, with a renewal at the option of the Bank. The Bank has sub-leased certain of its properties taken on lease. The rental expenses and sub-lease income is as follows:

	Six months period ended September 30,

16. 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	Definition
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 position 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 securities: Available for sale investments are principally comprised of debt securities and 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 values 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.

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, 2014 and September 30, 2014.

There have been no transfers between level 1 and 2 for the year ended March 31, 2014 and six months period ended September 30, 2014.

Derivatives: 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. Rupee interest rate swaps are commitments to exchange fixed and floating rate cash flows in rupees.

The Bank uses its pricing models to determine the fair value of its derivative instruments. These models use market inputs that are observable directly or indirectly.

Financing Receivable Credit Quality Indicators

Wholesale Loans

We have 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/impaired. Our 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.

Summary of significant accounting policies

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 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 under Financial Accounting Standard Board Accounting Standard Codification “FASB ASC” Topic 810 “Consolidations”. All significant inter-company accounts 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 income taxes, stock-based compensation, employee benefits, loan origination fees, derivative financial instruments, business combination and the presentation format and disclosures of the financial statements and related notes. The condensed consolidated balance sheet at March 31, 2014 has been derived from the Bank’s audited consolidated financial statement at that date. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included.

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 periods presented. Actual results could differ from these estimates. Material estimates included in these financial statements that are susceptible to change include the allowance for credit losses, the valuation of unquoted investments, other than temporary impairment, valuation of derivatives, stock-based compensation and impairment assessment of goodwill.

d. 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.

Retail

The Bank’s retail loan loss allowance consists of specific and unallocated allowances.

The Bank establishes 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 monitors loan to value ratios for loan against securities. The 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 past due 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 are not feasible.

The Bank also records 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 establishes 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 estimates its unallocated allowance for retail loans based on an internal credit slippage matrix, which measures the Bank’s historic losses for its standard loan portfolio. Subsequent recoveries, if any, against write-off cases, are adjusted to provision for credit losses in the consolidated statement of income.

Wholesale

The allowance for wholesale loans consists of specific and unallocated components. The allowance for such credit losses is evaluated on a regular basis by management and is 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 is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Loans are charged off against the allowance when management believes that the loan balance cannot be recovered. Subsequent recoveries, if any, against write-off cases, are 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 establishes 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.

Wholesale loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired 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.

In light of the significant growth in the size and diversity of its wholesale loan portfolio, the Bank has also established an unallocated allowance for wholesale standard loans based on the overall portfolio quality, asset growth, economic conditions and other risk factors. The Bank estimates its wholesale unallocated allowance based on an internal credit slippage matrix, which measures the Bank’s historic losses for its standard loan portfolio.

e. 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.

f. Revenue recognition

Interest income from loans and from investments is recognized on an accrual basis using effective interest method when earned except in respect of loans or investments placed on non-accrual status, where it is recognized when received. Nominal loan application fees are charged which offset the related costs incurred.

Fees and commissions from guarantees issued are amortized over the contractual period of the commitment, provided the amounts are collectible.

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.

g. Recently adopted accounting standards

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). As per the amendment, an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss (NOL) or other tax credit carry forward when settlement in this manner is available under the tax law. The assessment of whether settlement is available under the tax law would not consider future events (e.g., upcoming expiration of related NOL carry forwards). This classification should not affect an entity’s analysis of the realization of its deferred tax assets. Gross presentation in the rollforward of unrecognized tax positions in the notes to the financial statements would still be required. ASU 2013-11 is effective for interim and annual periods beginning on or after December 15, 2013. The adoption of this guidance effective April 1, 2014 did not have a material impact on the Bank’s consolidated financial position or results of operations.

h. Recently issued accounting pronouncements not yet effective

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This update clarifies the principles for revenue recognition in transactions involving contracts with customers. The guidance will be effective for the interim and annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Bank has not yet evaluated what impact, if any, the adoption of this guidance may have on the Bank’s financial condition, results of operations, or disclosures.

In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860)”. The amendments in this update change the current accounting outcome by requiring repurchase-to-maturity transactions to be accounted for as secured borrowings and for repurchase financing arrangement the amendments require separate accounting for a transfer of the financial asset executed contemporaneously with a repurchase agreement with same counterparty. The amendments also require new disclosures. The guidance will be effective for the interim and annual reporting periods beginning after December 15, 2014 and early adoption is not permitted. The Bank has not yet evaluated what impact, if any, the adoption of this guidance may have on the Bank’s financial condition, results of operations, or disclosures.

In August 2014, the FASB also issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU requires management to perform an assessment of going concern and provides specific guidance on when and how to assess or disclose going concern uncertainties. The new standard also defines terms used in the evaluation of going concern, such as “substantial doubt.” Following application, the Bank will be required to perform assessments at each annual and interim period, provide an assessment period of one year from the issuance date, and make disclosures in certain circumstances in which substantial doubt is identified. The amendment will be effective for the Bank for the first reporting period ending after December 15, 2016. Earlier application is permitted. The Bank does not expect this ASU to have an impact on its financial position, result of operations, or disclosures.

Fair value measurement

16. 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	Definition
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 position 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 securities: Available for sale investments are principally comprised of debt securities and 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 values 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.

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, 2014 and September 30, 2014.

The following table summarizes investments measured at fair value excluding investments carried at cost of Rs. 695.4 million on a recurring basis as of March 31, 2014, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

There have been no transfers between level 1 and 2 for the year ended March 31, 2014 and six months period ended September 30, 2014.

Derivatives: 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. Rupee interest rate swaps are commitments to exchange fixed and floating rate cash flows in rupees.

The Bank uses its pricing models to determine the fair value of its derivative instruments. These models use market inputs that are observable directly or indirectly.

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. Rupee interest rate swaps are commitments to exchange fixed and floating rate cash flows in rupees. 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 risk 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, 2014 and September 30, 2014, together with the fair values on each reporting date.

The Bank has not designated the above contracts as accounting hedges and accordingly the contracts are recorded at fair value on the balance sheet with changes in fair value recorded in earnings. The gross assets and the gross liabilities are recorded in ‘other assets’ and ‘accrued expenses and other liabilities’, respectively.

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 we have 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 comprise 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 his 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 case by case basis as may be assessed by the Bank. The remaining tenure of guarantees presently issued by the Bank and outstanding range from 1 day to 18.4 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 terms of FASB ASC 460-10 the Bank has recognized a liability of Rs. 1,301.7 million and Rs. 1,357.7 million as of March 31, 2014 and September 30, 2014 respectively, in respect of guarantees issued or modified. Based on historical trends, in terms of FASB ASC 450, the Bank has recognized a liability of Rs. 846.0 million and Rs. 895.8 million as of March 31, 2014 and September 30, 2014, respectively.

Total	Rs.	(1,480.7	)	Rs.	(1,605.4	)	US$	(25.9	)

As part of its risk management activities, the Bank continuously monitors the credit-worthiness 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.

Loan sanction letters

The Bank issues sanction letters indicating its intent to provide new loans to certain customers. The aggregate of loans contemplated in these letters that had not yet been disbursed was Rs. 616,957.6 million as of September 30, 2014. 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. The Bank has no commitment to lend under these letters. Among other things, the making of a loan is subject to a review of the credit-worthiness 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.

Estimated fair value of financial instruments

Estimated fair value of financial instruments

12. 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, 2014 and September 30, 2014. The estimated fair value amounts as of March 31, 2014 and September 30, 2014 have been measured as of the respective period end, 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 period end.

Financial instruments valued at carrying value

        The respective carrying values of certain on-balance-sheet financial instruments approximated their fair value. These financial instruments include cash and amounts due from banks, interest-bearing deposits in banks, securities purchased and sold under resale and repurchase agreements, accrued interest receivable, acceptances, accrued interest payable, and certain other assets and liabilities that are considered financial instruments. Carrying values were assumed to approximate fair values for these financial instruments as they are short-term in nature and their recorded amounts approximate fair values or are receivable or payable on demand.

Trading securities

Trading securities are carried at fair value based on quoted market prices. If quoted market prices did not exist, fair values were estimated using market yield on balance period to maturity on similar instruments and similar credit risk. For more information on the fair value of these securities, refer to Note 2.

Available for sale securities

Available for sale investments principally comprise of debt securities and 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 a market yield on the balance period to maturity on similar instruments and similar credit risks. The fair values of asset-backed and mortgage-backed securities are estimated based on revised estimated cash flows at each balance sheet date, discounted at current market pricing for transactions with similar risk. For more information on the fair value of these securities, refer to Note 3.

Loans

The fair values of consumer installment loans and other consumer loans that do not reprice frequently were estimated using discounted cash flow models. The discount rates were based on current market pricing for loans with similar characteristics and risk factors. Since, substantially all individual lines of credit and other variable rate consumer loans reprice frequently, with interest rates reflecting current market pricing, the carrying values of these loans approximate their fair values.

The fair values of commercial loans that do not reprice or mature within relatively short time frames were estimated using discounted cash flow models. The discount rates were based on current market interest rates for loans with similar remaining maturities and credit ratings. For commercial loans that reprice within relatively short time frames, the carrying values approximate their fair values.

For purposes of these fair value estimates, the fair values of impaired loans were computed by deducting an estimated market discount from their carrying values to reflect the uncertainty of future cash flows.

Deposits

The fair value of demand deposits, savings deposits, and money market deposits without defined maturities are the amounts payable on demand. For deposits with defined maturities, the fair values were estimated using discounted cash flow models that apply market interest rates corresponding to similar deposits and timing of maturities.

Short-term borrowings

The fair values of the Bank’s short-term debt were calculated based on a discounted cash flow model. The discount rates were based on yield curves appropriate for the remaining maturities of the instruments.

Long-term debt

The fair values of the Bank’s unquoted long-term debt instruments were calculated based on a discounted cash flow model. The discount rates were based on yield curves appropriate for the remaining maturities of the instruments.

Term placements

The fair values of term placements were estimated using discounted cash flow models. The discount rates were based on current market pricing for placements with similar characteristics and risk factors.

Goodwill and other intangible assets

6. Goodwill and other intangible assets

Goodwill arising from a business combination is tested at least on an annual basis for impairment. There were no changes in the carrying amount of goodwill of Rs. 74,937.9 million for the year ended March 31, 2014 and six months period ended September 30, 2014. The entire amount of goodwill was allocated to the retail business. The table below presents the gross carrying amount, accumulated amortization and net carrying amount, in total and by class of intangible assets as of March 31, 2014 and September 30, 2014:

Branch network intangible represents the benefit that the Bank received through the acquisition of a ready branch network from Centurion Bank of Punjab Limited (“CBoP”) as opposed to having to build a new one. The fair value attributable to the branch network intangible is the difference in the present values of the earnings (net of costs) that the Bank would have generated if the Bank had set up its own branches/ATMs (the “Hypothetical New Branch Network Earnings”) and the earnings (net of costs) that were generated because of the acquisition of CBoP (the “CBoP Branch Network Earnings”). Similar streams of revenues and operating costs (and therefore profits) from CBoP’s existing customer base and loan portfolio (includes net interest income, fees and commission) have been considered in determining the values of the Hypothetical New Branch Network Earnings and the CBoP Branch Network Earnings. Other assets including intangibles such as customer list, core deposits, loans, premises and equipment have been considered as assets of Hypothetical New Branch Network Earnings and the CBoP Branch Network Earnings and the value of these assets have been included in both of the networks. The aforesaid present values to compute the said intangible assets was intended to capture the advantages that the Bank received through the acquisition of a ready branch network from CBoP (as opposed to having to build a new one) in terms of time and of avoiding the administrative process required to obtaining branch licenses from the RBI. The Bank calculated the value of the customer list intangible through the cost approach by considering the estimated direct unit costs to source these customers multiplied by the number of customers. The Bank used the cost savings approach, i.e. the difference between the estimated cost of funds on deposit (interest cost and net maintenance costs) and the estimated cost of an equal amount of funds from an alternative source to calculate the core deposit intangible. The valuation of favorable leases intangibles was based on the cost saving to the Bank and future economic benefit until the lease expiry.

The aggregate amortization charged for the six months period ended September 30, 2013 and September 30, 2014 was Rs. 834.2 million and Rs. 210.5 million (US$ 3.4 million), respectively.

The estimated amortization expense for intangible assets for each of the five succeeding twelve months period is given in the table below:

The Bank has a credit risk mitigating/monitoring mechanism which is comprised of target market definitions, credit approval process, post-disbursement monitoring and remedial management procedures.

For wholesale credit risk in addition to the credit approval process the Bank has an approved framework for the review and approval of credit ratings. Credit Policies and Procedures articulate credit risk strategy and thereby the approach for credit origination, approval and maintenance. The Credit Policies generally address such areas as target markets, portfolio mix, prudential exposure ceilings, concentration limits, price and non-price terms, structure of limits, approval authorities, exception reporting system, prudential accounting and provisioning norms. These are reviewed in detail at annual or more frequent intervals. To ensure adequate diversification of risk, concentration limits have been set up in terms of borrower/business group, industry and risk grading.

For retail credit 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, 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 our own experience and industry data, in combination with the judgment of our senior officers. The Bank mines data on our borrower account behavior as well as static data regularly to monitor the portfolio performance of each product segment and use these as inputs in revising our product programs, target market definitions and credit assessment criteria to meet our twin objectives of combining volume growth and maintenance of asset quality.

As an integral part of the credit process, the Bank has a credit rating model appropriate to its wholesale and retail credit segments (see note 1d). The Bank monitors credit quality within its segments based on primary credit quality indicators. This internal grading is updated atleast annually.

Wholesale Loans

We have 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/impaired. Our 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.

Troubled debt restructuring (TDR)

When the Bank grants 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. 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, the loans are re-measured to reflect the impact, if any, on projected cash flows resulting from the modified terms. 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 uncollectible.

The following table summarizes our TDR modifications during the year ended March 31, 2014 and six months period ended September 30, 2014 presented by primary modification type and includes the financial effects of these modifications.

Summary of significant accounting policies (Policies)

6 Months Ended

Sep. 30, 2014

Principles of consolidation

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 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 under Financial Accounting Standard Board Accounting Standard Codification “FASB ASC” Topic 810 “Consolidations”. All significant inter-company accounts and transactions are eliminated on consolidation.

Basis of presentation

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 income taxes, stock-based compensation, employee benefits, loan origination fees, derivative financial instruments, business combination and the presentation format and disclosures of the financial statements and related notes. The condensed consolidated balance sheet at March 31, 2014 has been derived from the Bank’s audited consolidated financial statement at that date. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included.

Use of estimates

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 periods presented. Actual results could differ from these estimates. Material estimates included in these financial statements that are susceptible to change include the allowance for credit losses, the valuation of unquoted investments, other than temporary impairment, valuation of derivatives, stock-based compensation and impairment assessment of goodwill.

Allowance for credit losses

d. 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.

Retail

The Bank’s retail loan loss allowance consists of specific and unallocated allowances.

The Bank establishes 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 monitors loan to value ratios for loan against securities. The 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 past due 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 are not feasible.

The Bank also records 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 establishes 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 estimates its unallocated allowance for retail loans based on an internal credit slippage matrix, which measures the Bank’s historic losses for its standard loan portfolio. Subsequent recoveries, if any, against write-off cases, are adjusted to provision for credit losses in the consolidated statement of income.

Wholesale

The allowance for wholesale loans consists of specific and unallocated components. The allowance for such credit losses is evaluated on a regular basis by management and is 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 is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Loans are charged off against the allowance when management believes that the loan balance cannot be recovered. Subsequent recoveries, if any, against write-off cases, are 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 establishes 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.

Wholesale loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired 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.

In light of the significant growth in the size and diversity of its wholesale loan portfolio, the Bank has also established an unallocated allowance for wholesale standard loans based on the overall portfolio quality, asset growth, economic conditions and other risk factors. The Bank estimates its wholesale unallocated allowance based on an internal credit slippage matrix, which measures the Bank’s historic losses for its standard loan portfolio.

Income tax

e. 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.

Revenue recognition

f. Revenue recognition

Interest income from loans and from investments is recognized on an accrual basis using effective interest method when earned except in respect of loans or investments placed on non-accrual status, where it is recognized when received. Nominal loan application fees are charged which offset the related costs incurred.

Fees and commissions from guarantees issued are amortized over the contractual period of the commitment, provided the amounts are collectible.

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.

Recently adopted accounting standards

g. Recently adopted accounting standards

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). As per the amendment, an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss (NOL) or other tax credit carry forward when settlement in this manner is available under the tax law. The assessment of whether settlement is available under the tax law would not consider future events (e.g., upcoming expiration of related NOL carry forwards). This classification should not affect an entity’s analysis of the realization of its deferred tax assets. Gross presentation in the rollforward of unrecognized tax positions in the notes to the financial statements would still be required. ASU 2013-11 is effective for interim and annual periods beginning on or after December 15, 2013. The adoption of this guidance effective April 1, 2014 did not have a material impact on the Bank’s consolidated financial position or results of operations.

Recently issued accounting pronouncements not yet effective

h. Recently issued accounting pronouncements not yet effective

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This update clarifies the principles for revenue recognition in transactions involving contracts with customers. The guidance will be effective for the interim and annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Bank has not yet evaluated what impact, if any, the adoption of this guidance may have on the Bank’s financial condition, results of operations, or disclosures.

In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860)”. The amendments in this update change the current accounting outcome by requiring repurchase-to-maturity transactions to be accounted for as secured borrowings and for repurchase financing arrangement the amendments require separate accounting for a transfer of the financial asset executed contemporaneously with a repurchase agreement with same counterparty. The amendments also require new disclosures. The guidance will be effective for the interim and annual reporting periods beginning after December 15, 2014 and early adoption is not permitted. The Bank has not yet evaluated what impact, if any, the adoption of this guidance may have on the Bank’s financial condition, results of operations, or disclosures.

In August 2014, the FASB also issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU requires management to perform an assessment of going concern and provides specific guidance on when and how to assess or disclose going concern uncertainties. The new standard also defines terms used in the evaluation of going concern, such as “substantial doubt.” Following application, the Bank will be required to perform assessments at each annual and interim period, provide an assessment period of one year from the issuance date, and make disclosures in certain circumstances in which substantial doubt is identified. The amendment will be effective for the Bank for the first reporting period ending after December 15, 2016. Earlier application is permitted. The Bank does not expect this ASU to have an impact on its financial position, result of operations, or disclosures.

Segment information

Segment information

13. 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 makes loans, provides credit cards and debit cards, distributes third-party financial products, such as mutual funds and insurance, and provides advisory services to such customers. Revenues of the retail banking segment are derived from interest earned on retail loans, fees for banking and advisory 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 made 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 the proprietary account (including investments in government securities), foreign exchange operations and derivatives trading both on the 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. Wholesale banking segment includes unallocated tax balances and other items.

Summarized segment information for the six months periods ended September 30, 2013 and September 30, 2014:

AFS investments of Rs. 820,565.8 million and Rs. 996,147.8 million (US$ 16,087.7 million) as of March 31, 2014 and September 30, 2014, respectively, are eligible for placement towards the Bank’s statutory liquidity ratio requirements. These balances are subject to withdrawal and usage restrictions, but may be freely traded by the Bank within those restrictions. Of these investments, Rs. 670,603.5 million as of March 31, 2014 and Rs. 730,463.5 million (US$ 11,796.9 million) as of September 30, 2014, respectively, were kept as margins for clearing, collateral borrowing and lending obligation (CBLO), real time gross settlement (RTGS), with the Reserve Bank of India and other financial institutions.

The Bank conducts a review each reporting period to identify and evaluate investments that have indications of possible impairment. An investment in an equity or debt security is impaired if its fair value falls below its cost and the decline is considered other than temporary. Factors considered in determining whether a loss is temporary include length of time and extent to which fair value has been below cost, the financial condition and near-term prospects of the issuer and whether the Bank intends to sell or will be required to sell the security until the forecasted recovery. The Bank evaluated the impaired investments and has fully recognized an expense of Nil and Rs.1.8 million as other than temporary impairment for six months periods ended September 30, 2013 and September 30, 2014, respectively, because the Bank intends to sell the securities before recovery of their amortized cost. The Bank is of the opinion that the other unrealized losses on its investments in equity and debt securities as of September 30, 2014 are temporary in nature. The Bank’s review of impairment generally entails:

• identification and evaluation of investments that have indications of possible impairment;

• analysis of individual investments that have fair values of less than 95% of amortized cost, including consideration of the length of time the investment has been in an unrealized loss position;

• 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 analysis, as required under business policies.

As of March 31, 2014 and September 30, 2014, the Bank did not hold any debt securities with credit losses for which a portion of other-than-temporary impairment was recognized in other comprehensive income.

Held-to-maturity Securities

Investments

4. Investments, held to maturity

There were no HTM securities as of March 31, 2014 and September 30, 2014.

Under Indian GAAP, transfer from an HTM portfolio to an AFS portfolio are permitted by RBI regulations once every year and the Bank has made transfers in accordance with these regulations. However, the Bank has not established an HTM portfolio under US GAAP and therefore the investment classification made under US GAAP and Indian GAAP varies materially.

Commitments and contingencies

14. Commitments and contingencies

Commitments and contingent liabilities other than for off balance sheet financial instruments (see note 11) 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, 2014 and September 30, 2014 aggregated Rs. 2,492.2 million and Rs. 2,719.5 million, respectively.

Contingencies

The Bank is party to various legal proceedings in the normal course of business. The Bank estimates the provision for 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 of March 31, 2014 and September 30, 2014 aggregated to Rs. 4,090.9 million and Rs.4,215.6 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 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, employee residences and ATMs, with a renewal at the option of the Bank. The Bank has sub-leased certain of its properties taken on lease. The rental expenses and sub-lease income is as follows:

	Six months period ended September 30,
