standstill provisions in respect of asset classification”. At year-end fiscal 2017, we also initiated the process of change in ownership outside the strategic debt restructuring scheme of a borrower with gross debt outstanding of approximately Rs. 51.1 billion. A failure to arrive at a satisfactory resolution of this account would adversely impact our performance.

Further, the quality of our long-term project finance loan portfolio could be adversely impacted by several factors. Our loan portfolio includes project finance, corporate finance, and working capital loans to the infrastructure and related sectors, including power and construction, and commodity-based sectors such as coal and iron and steel, which are subject to global commodity price cycles. See also “—Our loan portfolio includes long-term project finance loans, which are particularly vulnerable to completion and other risks”. In certain cases, we have extended loan facilities to clients based on collateral consisting of equity shares and any volatility in the capital markets may impact the value of such collateral. Economic and project implementation challenges, in India and overseas, and declines or volatility in commodity prices, could result in some of our borrowers not being able to meet their debt obligations, including debt obligations that have already been restructured, resulting in an increase in non-performing loans. The inability of any of our borrowers to meet their debt obligations and the resultant increase in our non-performing loans may materially and adversely impact our financial performance.

There are uncertainties in respect of certain sectors due to challenging global and domestic economic conditions and high corporate leverage. The key sectors that have been impacted include power, mining, iron and steel, cement and rigs. At year-end fiscal 2016, the Bank’s fund based exposure and outstanding non-fund based facilities to companies internally rated below investment grade (excluding borrowers classified as non-performing or restructured) was Rs. 119.6 billion (1.3% of the Bank’s total exposure) to power (excluding exposure to a central public sector owned undertaking), Rs. 90.1 billion (1.0%) to mining, Rs. 77.8 billion (0.8%) to iron & steel, Rs. 66.4 billion (0.7%) to cement and Rs. 25.1 billion (0.3%) to rigs. Further, the Bank’s fund based exposure and outstanding non-fund based facilities to promoter entities internally rated below investment grade where the underlying is partly linked to these sectors was Rs. 61.6 billion (0.7%). At year-end fiscal 2017, ICICI Bank’s fund based exposure and outstanding non-fund based facilities to companies internally rated below investment grade (excluding accounts classified as non-performing or restructured) was Rs. 62.3 billion (0.7% of the Bank’s total exposure) to power (excluding exposure to a central public sector owned undertaking), Rs. 52.3 billion (0.6%) to mining, Rs. 39.7 billion (0.4%) to iron & steel, Rs. 2.9 billion to cement and Rs. 0.4 billion to rigs. Further, the Bank’s fund based exposure and outstanding non-fund based facilities to promoter entities internally rated below investment grade where the underlying is partly linked to these sectors was Rs. 32.6 billion (0.3%). The decrease of Rs. 250.2 billion in the aggregate fund based exposure and non-fund based outstanding to companies internally rated below investment grade in the above sectors and promoter entities was due to classification of Rs. 200.5 billion as non-performing and reduction in exposure and net rating upgrades of Rs. 49.7 billion. The exposure to companies internally rated below investment grade in the above sectors and promoter entities includes the non-fund based facilities outstanding in respect of accounts included in this portfolio where the fund based facilities outstanding have been classified as non-performing. Apart from this, the non-fund based facilities outstanding to borrowers classified as non-performing was Rs. 19.3 billion. Any additional classification of such fund based exposures and outstanding non-fund based facilities as non-performing may materially and adversely impact our business.

During fiscal 2016 and fiscal 2017, the increase in additions to non-performing loans resulted in a significant increase in our provisions. It also impacted net interest margin, as we do not accrue interest on non-performing loans. In July 2017, while rating agency, Moody’s, reaffirmed the Bank’s senior unsecured debt rating at baa3, the baseline credit assessment of the Bank was lowered from baa3 to ba1 and the rating outlook on the Bank’s senior unsecured debt was changed from positive to stable. The high level of, and increase in, non-performing loans is expected to result in high provisions and to continue to adversely impact our net interest margin in fiscal 2018 as well. The non-accrual of income on loans subjected to restructuring or special structuring involving a standstill period under applicable regulatory guidelines also negatively impacts our net interest income and net interest margin.

Provisions are created by a charge to expense, reflecting our estimates of loan losses and the credit risks in our portfolio, which may not be adequate to cover further increases in the amount of non-performing loans or further deterioration in our non-performing loan portfolio. In addition, for the year ended March 31, 2016, the Reserve Bank of India’s annual supervisory process assessed higher provision than we had reported. While we have given effect to the impact of the changes in provisioning arising out of the Reserve Bank of India’s supervisory process in the financial statements for the year ended March 31, 2017, the Reserve Bank of India’s supervisory process for the year ended fiscal 2017 may result in further divergences between the Reserve Bank of India’s assessed provisions and our reported provisions. Such divergence would require us to further change our provisioning processes, potentially resulting in higher provisioning expenses. See also “—If regulators continue to impose increasingly stringent requirements regarding non-performing loans and provisioning for such loans, or if the provisions for such loans otherwise increase, our business will suffer.”

Our ability to adequately control our non-performing loans in our portfolio will depend on several factors, including a pick-up in economic growth, a favorable inflation and interest rate environment, increase in credit growth and resolution of stressed assets. In addition, the requirement to complete the resolution process within the stipulated timeline to avoid liquidation of the borrower may impact recoveries from these stressed accounts. In the event borrowers go into liquidation, the additional credit losses may be significant.

See also “ —The enhanced supervisory and compliance environment in the financial sector increases the risk of regulatory action, whether formal or informal. Following the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past”, “Business—Classification of Loans”, “Operating and Financial Review and Prospects” and “ Supervision and Regulation—Loan Loss Provisions and Non-performing Assets—Asset Classification ”.

If regulators continue to impose increasingly stringent requirements regarding non-performing loans and provisioning for such loans, or if the provisions for such loans otherwise increase, our business will suffer.

If regulator including the Reserve Bank of India continues to impose increasingly stringent requirements regarding non-performing loans and provisioning for such loans, or if the provisions for such loans otherwise increase, the level of non-performing loans could increase, the overall quality of our loan portfolio could deteriorate, our credit ratings and liquidity may be adversely impacted, our reputation may be adversely impacted and our business, our future financial performance and the price of our equity shares and ADSs could be adversely impacted. See also “—If we are unable to adequately control the level of non-performing loans in our portfolio, our business will suffer” .

Banks in India are required to make provisions for all their loans in accordance with guidelines issued by the Reserve Bank of India, which prescribes the accounting for loss provisioning, unlike in the United States and European Union where a separate body sets accounting standards, including for provisioning. Under the Reserve Bank of India guidelines, Indian banks are required to make provisions on standard, sub-standard and doubtful assets at rates prescribed by the Reserve Bank of India. We make provisions on retail non-performing loans at the borrower level in accordance with the retail assets provisioning policy of the Bank, subject to the minimum provisioning levels prescribed by the Reserve Bank of India. We hold higher specific provisions on retail loans and advances than the minimum regulatory requirement and make provisions on restructured/rescheduled loans and advances in accordance with the applicable Reserve Bank of India guidelines on restructuring of loans and advances by banks. In addition to the specific provision on non-performing assets, we maintain a general provision on standard loans and advances and restructured loans and advances at rates prescribed by the Reserve Bank of India.

The Reserve Bank of India has substantially expanded its guidance relating to the identification and classification of non-performing assets over the last three years, which has resulted in an increase in our loans classified as non-performing and an increase in provisions.

Effective April 1, 2014, the Reserve Bank of India issued guidelines which included a framework for early identification and resolution of stressed assets. The guidelines introduced an asset classification category of “special mention accounts”, which comprises cases that are not yet restructured or classified as non-performing but which exhibit early signs of stress, as determined by various parameters. Banks are also required to share data with each other on a category of special mention accounts, form joint lenders’ forums and devise action plans for the joint resolution of these accounts. Any failure to do so within stipulated timeframes results in accelerated provisioning for such cases and may materially and adversely impact our business and future financial performance.

During the three months ended December 31, 2015, against the backdrop of continuing challenges in the corporate sector, the Reserve Bank of India articulated an objective of early and conservative recognition of stress and provisioning and held discussions with and asked a number of Indian banks, including us, to review certain loan accounts and their classification over the six months ended March 31, 2016. As a result of the challenges faced by the corporate sector and the discussions with and review by the Reserve Bank of India, non-performing loans increased significantly in the banking system during the second half of fiscal 2016.

During fiscal 2017, the additions to non-performing loans, including slippages from restructured loans, continued to remain elevated as the corporate sector challenges continued due to the slowdown in economic growth, low corporate profitability and subdued investment activity. The slowdown in economic growth was primarily in the industrial and services sectors, with growth in the industrial sector moderating to 5.6% during fiscal 2017 compared to 8.8% during fiscal 2016, and in the services sector to 7.7% in fiscal 2017 compared to 9.7% in fiscal 2016. Further, during the second half of fiscal 2017, there was a reduction in the availability of cash caused by the withdrawal of high denomination currency notes by the government of India, which also impacted businesses. While several companies are working with banks to restructure and reorganize their businesses and reduce their leverage through sales of businesses and assets, the process of resolving stressed

assets remained slower than expected due to delays in decision making at the Joint Lenders’ Forum that was set up to explore options for early resolution of stress in loan accounts. Several measures were announced by the Reserve Bank of India during the year to enable early resolution of assets. However, the continued challenges in the operating and recovery environment adversely impacted the pace of resolution leading to a significant increase in non-performing loans, including slippages from restructured loans, and provisions during fiscal 2017. Any further increases in non-performing loans and provisions may materially and adversely impact our business and future financial performance.

Our gross non-performing loans increased significantly from Rs. 173.9 billion at year-end fiscal 2015 to Rs. 293.2 billion at year-end fiscal 2016 and to Rs. 458.9 billion at year-end fiscal 2017 . Our provisions for non-performing assets including restructuring related provisions increased from Rs. 77.2 billion in fiscal 2016 to Rs. 157.5 billion in fiscal 2017, primarily due to an increase in additions to non-performing assets in the corporate and small and medium enterprises loan portfolio, including reclassifications of restructured loans as non-performing loans due to the failure of the borrowers to perform as per the debt restructuring terms and specific provisions on cases where strategic debt restructuring was initiated. Our provisions on standard assets decreased from Rs. 3.2 billion in fiscal 2016 to a write-back of Rs. 3.7 billion in fiscal 2017, primarily due to higher slippages to the non-performing category. Further, in view of the uncertainties relating to certain sectors and the time that it may take to resolve the Bank’s exposures to these sectors, the Bank made a collective contingency and related reserve of Rs. 36.0 billion at year-end fiscal 2016 towards the Bank’s exposure to these sectors. During fiscal 2017, ICICI Bank allocated the full amount of the collective contingency and related reserve towards the provisions for loans and fixed assets acquired in partial satisfaction of loans.

In April 2017, the Reserve Bank of India directed banks to put in place board-approved policies for making provisions for standard assets at rates higher than those prescribed by the Reserve Bank of India, based on industry sectors and an assessment of sectoral risks and trends. In particular, the Reserve Bank of India highlighted risks in the telecom sector and directed banks to complete the assessment with respect to this sector by June 30, 2017. Furthermore, in April 2017, the Reserve Bank of India required banks to disclose the divergence in asset classification and provisioning between what banks report and what the Reserve Bank of India assess through the Reserve Bank of India’s annual supervisory process. For the year ended March 31, 2016, as compared to our assessment, the Reserve Bank of India’s assessment of gross non-performing assets was Rs. 51.0 billion higher, net non-performing assets was Rs. 40.3 billion higher and provisions for non-performing assets was Rs. 10.7 billion higher. After adjusting for these divergences, our net profit after tax for the year ended March 31, 2016 would be Rs. 90.3 billion rather than Rs. 97.3 billion. For further information, see also Note 15 to Schedule 18 “Notes Forming part of the Accounts” to the consolidated financial statements. While the impact of changes in classification and provisioning arising out of the Reserve Bank of India’s supervisory process for the year ended March 31, 2016 has been fully given effect to in the audited financial statements for the year ended March 31, 2017, additional divergences may arise from the Reserve Bank of India’s supervisory process for the year ended March 31, 2017. Such divergences would require us to further change our classification and provisioning processes and would also result in gross non-performing assets, net non-performing assets, provisions for non-performing assets and net profit after tax being different from what we report herein should divergences be adjusted for. There can be no assurance that such disclosures will not impact us, our reputation, our business and future financial performance. Further, apart from the Reserve Bank of India that regulates us, there could be a possibility of other regulatory bodies also taking enforcement action based on such disclosures. Our subsidiaries are also regulated by their respective regulatory bodies. Similar to us, there may arise a requirement for additional disclosures from our subsidiaries in future, which may have an adverse impact on us.

In June 2017, the Reserve Bank of India directed banks to commence proceedings under the Insolvency and Bankruptcy Code, enacted in 2016, in respect of certain corporate borrowers. Under this Code, a resolution plan for these borrowers would be required to be finalized within specified timeframes, failing which the borrowers would go into liquidation. The Reserve Bank of India has also specified higher provisions in respect of loans to these borrowers. Further, with respect to other identified stressed accounts, the banks are required to finalize a resolution plan within six months, failing which banks shall be required to file for insolvency proceedings under the Code. Given the limited experience of this framework, there can be no assurance that successful resolution of these borrowers’ liabilities would be achieved, and should one or more of these borrowers go into liquidation, the provisioning requirement and credit loss on these loans could result in significantly higher provisions and recovery from these borrowers could be significantly lower. The Reserve Bank of India may identify other corporate borrowers for action under the Insolvency and Bankruptcy Code and may require banks to commence similar proceedings, which may further impact our provisioning and credit loss. In addition, the requirement to complete the resolution process within the stipulated timeline to avoid liquidation of the borrower may impact recoveries from these stressed accounts. In the event borrowers go into liquidation, the additional credit losses may be significant.

From fiscal 2019, banks in India will migrate to the new accounting standards, Ind AS, which largely converges the Indian accounting standards with International Financial Reporting Standards. Further, banks migrating to the advanced measurement approach for operational risk and internal ratings-based approaches for credit risk under Basel II are required to follow the prescribed minimum loss given default levels for capital adequacy computation and treat restructured assets as non-performing assets for capital adequacy purposes. Compliance with these new standards may result in an increase in loans classified as non-performing and provisioning costs for banks, including us.

Our strategy going forward with respect to our loan portfolio comprises proactive monitoring of loan portfolios across businesses; improvement in the portfolio mix by focusing on retail lending and lending to higher-rated companies; reduction of concentration risk; and resolution of exposures through asset sales by borrowers, changes in management and working with stakeholders to ensure that companies are able to operate at an optimal level and generate cash flows. Our strategy will also depend on the resolution of stressed assets within the specified timeframe. There can be no assurance that we will be able to successfully implement our strategy and control or reduce the level of non-performing assets, or that our future recoveries on non-performing assets will be similar to our past experience of recoveries on non-performing assets. If we cannot successfully control our non-performing assets, our business, future financial performance and the price of our equity shares and ADSs could be materially and adversely impacted.

Our standard loan portfolio includes loans subject to standstill provisions in respect of asset classification.

Our standard loan portfolio includes loans to borrowers where we, alone or with other lenders, have invoked schemes permitted by the Reserve Bank of India, including strategic debt restructuring and change in management, which provide for a standstill period during which the loan continues to be classified as standard even if the default in payment of interest or principal would otherwise have required the loan to be classified as non-performing. Interest on the loan do not accrue during such standstill period, and is recognized by us only if received in cash. This standstill period is intended to allow time for the change in management and resolution of the borrowers’ liabilities. A failure to arrive at a resolution by the end of the standstill period would result in such loans being classified as non-performing.

At year-end fiscal 2017, our standard loan portfolio included loans aggregating Rs. 64.5 billion to borrowers within the standstill period, of which Rs. 26.4 billion was part of our exposure internally rated below investment grade to the power, mining, iron & steel, cement and rigs sectors and promoter entities. If there is a substantial increase in such loans, or if such loans are classified as non-performing, it could have a material adverse effect on our business, our future financial performance and the price of our equity shares and ADSs. In addition, during the standstill period, we are not allowed foreclose on such loans or otherwise liquidate any collateral that we may have. Our inability to do so may result in a failure to recover the expected value from such loan or collateral, and could have a material adverse effect on our business and future financial performance.

If our restructured borrowers fail to perform as expected and the loans to them are recategorized to the non-performing category, our business will suffer.

Our standard assets also include restructured standard loans. See also “ Business—Classification of Loans—Restructured Loans ”. At year-end fiscal 2017, our restructured standard loans were Rs. 47.8 billion . In recent years, we have experienced a significant increase in the amount of standard restructured loans that were re-categorized to the non-performing category. The principal amount of such re-categorized loans increased from Rs. 7.3 billion in fiscal 2014 to Rs. 45.3 billion in fiscal 2015 and further to Rs. 53.0 billion in fiscal 2016. The restructured loans re-categorized to the non-performing category declined to Rs. 48.4 billion in fiscal 2017. The failure of some of our restructured borrowers to perform as expected and the Reserve Bank of India’s review of the loan portfolios of Indian banks results in an increase in non-performing loans. The performance of our restructured borrowers is dependent on various factors, including economic conditions, in India and globally, movements in global commodity markets and exchange rates, rise in interest rates, inflation and distress in certain sectors, in addition to regulatory change.

See also and “— If regulators continue to impose increasingly stringent requirements regarding non-performing loans and provisioning for such loans, or if the provisions for such loans otherwise increase, our business will suffer ” and “ Supervision and Regulation—Loan Loss Provisions and Non-Performing Assets—Restructured loans ”.

The exposures of our international branches and subsidiaries or our exposure to the securities of reconstruction companies could generally affect our business, financial condition and results of operations.

The loan portfolio of our international branches and subsidiaries includes foreign currency loans to Indian companies for their Indian operations (where permitted by regulation) as well as for their overseas ventures, including cross-border acquisitions. This exposes us to specific additional risks including the failure of the acquired entities to perform as expected, and our inexperience in various aspects of the economic and legal framework in overseas markets. See also “—Our international operations increase the complexity of the risks that we face” .

Further, the classification of the loan portfolio of our overseas branches and subsidiaries is also subject to the regulations of respective local regulators. Such loans that are identified as impaired as per host country regulations for reasons other than record of recovery, but which are standard as per the extant Reserve Bank of India guidelines, are classified as non-performing to the extent of the amount of outstanding loan in the host country. Such classification of loans as non-performing based on host country regulations may lead to an adverse impact on our business, our future financial performance and the price of our equity shares and ADSs .

We also have investments in security receipts arising from the sale of non-performing assets by us to reconstruction companies registered with the Reserve Bank of India. See also “Business—Classification of Loans” . There can be no assurance that reconstruction companies will be able to recover these assets and redeem our investments in security receipts and that there will be no reduction in the value of these investments. Any such inability to recover assets or redeem our investments without a diminution in value could generally affect our business, financial condition and results of operations. In September 2016, the Reserve Bank of India issued a framework for sale of stressed assets. As per this framework, with effect from April 1, 2017, provisions held for investment in security receipts will be subject to a floor of provisioning rate applicable to the underlying loans (the provisions the bank would have had to make if the loans had continued to be held in its books), if more than 50% of the security receipts are held by the bank that sold the loans. The threshold of 50% will be reduced to 10% from April 1, 2018 as per the framework. Further, the framework requires banks to maintain an internal list of stressed assets identified for sale and review assets classified as ‘doubtful’ above a threshold amount on a periodic basis with a view to consider a sale or other disposition.

Our loan portfolio includes long-term project finance loans, which are particularly vulnerable to completion and other risks.

We expect long-term project finance to be an area of growth in our business over the medium to long-term, and the quality of this portfolio could be adversely impacted by several factors. The viability of these projects depends upon a number of factors, including market demand, government policies, the processes for awarding government licenses and access to natural resources and their subsequent judicial or other review, the financial condition of the government or other entities that are the primary customers for the output of such projects and the overall economic environment in India and the international markets. These projects are particularly vulnerable to a variety of risks, including risks of delays in regulatory approvals, environmental and social issues, completion risk and counterparty risk, which could adversely impact their ability to generate revenues. In the past, we have experienced a high level of default and restructuring in our industrial and manufacturing project finance loan portfolio as a result of the downturn in certain global commodity markets and increased competition in India. Our loans to the power sector were 5.8% of our total loans at year-end fiscal 2015, 5.6% at year-end fiscal 2016 and 5.8% at year-end fiscal 2017. Our non-performing loans in the power sector increased from Rs. 0.7 billion in fiscal 2015 to Rs. 17.5 billion in fiscal 2016 and to Rs. 64.0 billion in fiscal 2017. Power projects face a variety of risks, including access to fuel such as coal and gas, and off-take of the power produced. For example, we are lenders to a large gas-based power plant in the state of Maharashtra which has been impacted by the non-availability of gas. Coal based power projects in India have experienced delays primarily due to environmental concerns around coal mining and the de-allocation of coal blocks allocated to companies. While the Indian government has commenced the auction of these de-allocated coal blocks, the commencement of operations and financial performance of projects linked to these coal blocks continues to be uncertain. In addition, power projects inherently have high leverage levels and volatility in capital markets and concerns about the implementation of these projects and their future cash flows may constrain the availability of equity funding for such projects. Any reduction in the output of operational power plants or the projected output of newly-commissioned or under-implementation power projects due to lower availability of fuel, higher fuel costs that cannot be passed through to purchasers and inability of state-owned power distribution utilities to purchase or pay for power due to their financial condition, or a decline in the price of power, may have an adverse impact on the financial condition of power producers and their ability to service their debt obligations, including to us. We cannot be sure that these projects will begin operations as scheduled or perform as anticipated. A change in the ownership and management of these projects could further delay the commencement of operations. We may see an increase in our non-performing assets or restructured assets in case of delays from the scheduled commercial date of operations of such projects, which are longer than that permitted by the Reserve Bank of India guidelines.

Our loan portfolio also includes project finance, corporate finance, and working capital loans to commodity-based sectors such as iron and steel and mining, which are subject to similar and additional risks, as well as global commodity price cycles. During fiscal 2016, due to a slowdown in global demand for steel, there was a sharp decline in global steel prices, which in turn impacted Indian steel companies. Capacity utilization of steel companies declined and profitability came under pressure. The Indian government announced certain policy measures, including a minimum price for procuring steel from overseas markets, which have benefited the Indian steel sector. However, we cannot be certain that these measures will continue to remain in place in the future or that there will be a significant improvement in the profitability of steel companies if global steel prices continue to remain weak. We may see an increase in non-performing assets in the event the profitability of steel companies continues to remain under pressure. A slowdown in the Indian and global economy may exacerbate the risks for the projects that we have financed. Future project finance losses or high levels of loan restructuring

could have a materially adverse effect on our profitability and the quality of our loan portfolio and the price of our equity shares and ADSs .

We have a high concentration of loans to certain customers, borrower groups and sectors and if a substantial portion of these loans become non-performing, the overall quality of our loan portfolio, our business and the price of our equity shares and ADSs could be adversely affected.

Our loan portfolio and non-performing asset portfolio have a high concentration in certain types of customers. ICICI Bank’s policy is to limit its exposure to any particular industry (other than retail loans) to 15.0% of its total exposure. Our loans and advances to the retail finance segment constituted 50.2% of our gross loans and advances at year-end fiscal 2017. Our loans and advances to the power sector was 5.8%, to the iron and steel sector was 4.7%, to the infrastructure sector (excluding power) was 4.5% and to the non-finance services sector was 4.4% of our gross loans and advances at year-end fiscal 2017.

There are uncertainties in respect of certain sectors due to global and domestic economic conditions and high corporate leverage. The key sectors that have been impacted include power, mining, iron and steel, cement and rigs. At year-end fiscal 2016, the Bank’s fund based exposure and outstanding non-fund based facilities to companies internally rated below investment grade (excluding borrowers classified as non-performing or restructured) was Rs. 119.6 billion (1.3% of the Bank’s total exposure) to power (excluding central public sector owned undertaking), Rs. 90.1 billion (1.0%) to mining, Rs. 77.8 billion (0.8%) to iron & steel, Rs. 66.4 billion (0.7%) to cement and Rs. 25.1 billion (0.3%) to rigs. Further, the Bank’s fund based exposure and outstanding non-fund based facilities to promoter entities internally rated below investment grade where the underlying is partly linked to these sectors was Rs. 61.6 billion (0.7%). At year-end fiscal 2017, ICICI Bank’s fund based exposure and outstanding non-fund based facilities to companies internally rated below investment grade (excluding accounts classified as non-performing or restructured) was Rs. 62.3 billion (0.7% of the Bank’s total exposure) to power (excluding central public sector owned undertaking), Rs. 52.3 billion (0.6%) to mining, Rs. 39.7 billion (0.4%) to iron & steel, Rs. 2.9 billion to cement and Rs. 0.4 billion to rigs. Further, the Bank’s fund based exposure and outstanding non-fund based facilities to promoter entities internally rated below investment grade where the underlying is partly linked to these sectors was Rs. 32.6 billion (0.3%). The decrease of Rs. 250.2 billion in the aggregate fund based exposure and non-fund based outstanding to companies internally rated below investment grade in the above sectors and promoter entities was due to classification of Rs. 200.5 billion as non-performing and reduction in exposure and net rating upgrades of Rs. 49.7 billion. The exposure to companies internally rated below investment grade in the above sectors and promoter entities includes the non-fund based facilities outstanding in respect of accounts included in this portfolio where the fund based facilities outstanding have been classified as non-performing. In view of the uncertainties relating to the above sectors and the time that it may take to resolve the Bank’s exposures to these sectors, the Bank made a collective contingency and related reserve of Rs. 36.0 billion at year-end fiscal 2016 towards the Bank’s exposure to these sectors. This reserve was over and above the provisions required for non-performing and restructured loans as per Reserve Bank of India guidelines but, as a prudent matter, was permitted under Reserve Bank of India guidelines and Indian GAAP. During fiscal 2017, ICICI Bank re-allocated the full amount of the collective contingency and related reserve towards the provisions for loans and fixed assets acquired in partial satisfaction of loans. See also “ Business—Classification of Loans ”.

Pursuant to the guidelines of the Reserve Bank of India, the Bank’s credit exposure to an individual borrower must not exceed 15.0% of its capital funds, unless the exposure is with regards to an infrastructure project. Capital funds refer to Tier 1 and Tier 2 capital after regulatory adjustments as per the Reserve Bank of India guideline ‘Master Circular - Basel III Capital Regulations’. ICICI Bank’s exposure to a group of companies under the same management control generally must not exceed 40.0% of its capital funds unless the exposure is towards an infrastructure project, as per the Reserve Bank of India guidelines. Banks may, in exceptional circumstances, with the approval of their boards, enhance the exposure by 5.0% of capital funds (i.e., aggregate exposure can be 20.0% of capital funds for an individual borrower and aggregate exposure can be 45.0% of capital funds for a group of companies under the same management). At year-end fiscal 2017, our largest non-bank borrower accounted for approximately 12.1% of our capital funds. The largest group of companies under the same management control accounted for approximately 23.4% of our capital funds. The Bank’s exposure to its 20 largest borrowers (including banks) was approximately 12.9% of our total exposure, and our credit exposure to our 20 largest borrowers (including banks) was approximately 13.2% of the Bank’s total credit exposure at year-end fiscal 2017.

In December 2016, the Reserve Bank of India released a framework for large exposures with limits on exposure of banks to single counterparty and a group of connected counterparties. As per this framework, the sum of all the exposure values of a bank to a single counterparty must not be higher than 20% of the bank’s

available eligible capital base at all times and the sum of all the exposure values of a bank to a group of connected counterparties must not be higher than 25% of the bank’s available eligible capital base at all times. This framework is expected to be implemented in full by April 1, 2019 and the extant exposure norms applicable for credit exposure to individual borrower or to group of companies /group of companies under same management control will no longer be applicable from that date. Banks are required to gradually adjust their exposures so as to comply with the limits given in the framework for large exposures. In August 2016, the Reserve Bank of India issued guidelines proposing limits on the aggregate exposure of the banking system to large borrowers, with lending beyond the specified limits attracting higher risk weights and provisioning. These guidelines, and our focus on controlling and reducing concentration risk, may restrict our ability to grow our business with some customers, and require us to reduce our exposure to some groups.

Our strategy with respect to our loan portfolio comprises proactive monitoring of loan portfolios across businesses; improvement in the portfolio mix by focusing on retail lending and lending to higher-rated companies; reduction of concentration risk; and resolution of exposures through asset sales by borrowers, changes in management and working with stakeholders to ensure that companies are able to operate at an optimal level and generate cash flows. We have created a framework for managing concentration risk which specifies various single borrower and group exposure thresholds and the authorization matrix that must be followed in case exposures exceed the stipulated thresholds. There can be no assurance that we will be able to successfully implement our strategy and control or reduce the level of concentration. See also “Business—Loan Portfolio—Loan Concentration”.

Our banking and trading activities are particularly vulnerable to interest rate risk and volatility in interest rates could adversely affect our net interest margin, the value of our fixed income portfolio, our income from treasury operations, the quality of our loan portfolio and our financial performance.

Interest rates in India are impacted by a range of factors including inflation, fiscal deficit and government borrowing, monetary policy and market liquidity. For instance, in July 2013, with a view to manage the volatility in the exchange rate, the Reserve Bank of India introduced measures to reduce liquidity in the Indian banking system and increase the cost of borrowing from the Reserve Bank of India.

As a result of certain reserve requirements of the Reserve Bank of India, we are more structurally exposed to interest rate risk than banks in many other countries. See also “ Supervision and Regulation—Legal Reserve Requirements ”. These requirements result in our maintaining a large portfolio of fixed income government of India securities, and we could be materially adversely impacted by a rise in interest rates, especially if the rise were sudden or sharp. Realized and marked-to-market gains or losses on investments in fixed income securities, including government of India securities, are an important element of our profitability and are impacted by movements in market yields. A rise in yields on government securities reduces our profits from this activity and the value of our fixed income portfolio. These requirements also have a negative impact on our net interest income and net interest margin because we earn interest on a portion of our assets at rates that are generally less favorable than those typically received on our other interest-earning assets. We are also exposed to interest rate risk through our treasury operations as well as the operations of certain of our subsidiaries, including ICICI Lombard General Insurance Company, which has a portfolio of fixed income securities, and ICICI Securities Primary Dealership, which is a primary dealer in government of India securities. In our asset management business, we manage money market mutual funds whose performance is impacted by a rise in interest rates, which adversely impacts our revenues and profits from this business. See also “— Risks Relating to India and Other Economic and Market Risks—A prolonged slowdown in economic growth or rise in interest rates in India could cause our business to suffer ” and “— Risks Relating to India and Other Economic and Market Risks—Current account deficits, including trade deficits, and capital flow and exchange rate volatility could adversely affect our business and the price of our equity shares and ADSs ”.

If the yield on our interest-earning assets does not increase at the same time or to the same extent as our cost of funds, or if our cost of funds does not decline at the same time or to the same extent as the decrease in yield on our interest-earning assets, our net interest income and net interest margin would be adversely impacted. Any systemic decline in low cost funding available to banks in the form of current and savings account deposits would adversely impact our net interest margin. The Reserve Bank of India has deregulated the interest rate on savings deposits, following which some of the smaller banks in India are offering higher interest rates on their savings deposit accounts. If other banks with whom we compete similarly raise their savings account deposit rates, we may also have to do so to remain competitive and this would adversely impact our cost of funds. In December 2015, the Reserve Bank of India released guidelines on computation of lending rates based on the marginal cost of funds methodology which is applicable on incremental lending from April 1, 2016. This change in the methodology for calculating cost of funds led to lower lending rates, and may lead to more frequent revisions in lending rates due to the prescribed monthly review of cost of funds. See also

“ Business—Loan Portfolio—Loan Pricing” and “Supervision and Regulation—Regulations Relating to Advancing Loans ”. This may impact the yield on our interest-earning assets, our net interest income and net interest margin. During November 2016-March 2017, there was a significant increase in savings and current account deposits in the banking system following the government of India’s decision to withdraw high denomination currency notes. The surge in low cost funds resulted in an increase in liquidity in the banking system and a reduction in the cost of funds for banks, including for us. The subsequent reduction in lending rates were however higher compared to the decline in cost of funds, as banks were seeking to deploy the excess liquidity. Further, customers with floating rate loans also repriced their existing loans at the lower rate. Earlier, banks were not permitted to extend fixed rate loans at a rate of interest lower than the base rate. This restriction no longer applies to fixed rate loans of tenor above three years under the new guideline, and competition among lenders may lead to lower lending rates and result in reduced net interest income. If there are increases in our cost of funds and if we are unable to pass on the increases fully into our lending rates, our net interest margins and profitability would be adversely impacted. In January 2017, we reduced our marginal cost of funds based lending rate, which is the benchmark rate for floating rate loans offered by us, by 70 basis points across tenures. Some of the other large banks in India also announced a downward revision in their marginal cost of funds based lending rates. Such revisions in benchmark lending rates may impact the yield on our interest-earning assets, our net interest income and net interest margin.

Further, any tightening of liquidity and volatility in international markets may limit our access to international bond markets and result in an increase in our cost of funding for our international business. Continued volatility in international markets could constrain and increase the cost of our international market borrowings and our ability to replace maturing borrowings and fund new assets. Our overseas banking subsidiaries are also exposed to similar risks.

High and increasing interest rates or greater interest rate volatility would adversely affect our ability to grow, our net interest margins, our net interest income, our income from treasury operations and the value of our fixed income securities portfolio.

We are subject to the directed lending requirements of the Reserve Bank of India, and any shortfall in meeting these requirements may be required to be invested in Government schemes that yield low returns, thereby impacting our profitability. We may also experience a higher level of non-performing assets in our directed lending portfolio, which could adversely impact the quality of our loan portfolio, our business and the price of our equity shares and ADSs.

Under the directed lending norms of the Reserve Bank of India, banks in India are required to lend 40.0% of their adjusted net bank credit to certain eligible sectors, categorized as priority sectors. Of this, banks have sub-targets for lending to key sectors. A proportion of 18.0% of adjusted net bank credit is required to be lent to the agricultural sector. The norms applicable up to and including fiscal 2015 required 18.0% of adjusted net bank credit lent to the agriculture sector to include direct agricultural advances of at least 13.5% and indirect agricultural advances of not more than 4.5%. Direct agricultural advances include loans made directly to individual farmers or groups of individual farmers for agriculture and related activities. Indirect agricultural advances include loans for purposes linked to agriculture, such as loans to food and agri-processing units, finance for hire-purchase schemes for distribution of agricultural machinery and implements, financing farmers indirectly through the co-operative system and loans for the construction and operation of storage facilities. Loans to identified weaker sections of society must comprise 10.0% of adjusted net bank credit. These requirements were to be met as of the last reporting Friday of the fiscal year with reference to the adjusted net bank credit of the previous fiscal year till fiscal 2016. From fiscal 2017, the requirement is assessed on a quarterly basis. These requirements apply to ICICI Bank on a standalone basis.

The Reserve Bank of India issued revised directed lending norms applicable from fiscal 2016 onwards. The sub-targets for direct and indirect lending to agriculture have been combined. Two new sub-targets, a target of 8.0% of adjusted net bank credit to small and marginal farmers and a 7.5% lending target to micro-enterprises, have been introduced and apply in a phased manner over fiscal 2016 and fiscal 2017. The balance of the priority sector lending requirement can be met by lending to a range of sectors, including small businesses, medium enterprises, renewable energy, social infrastructure and residential mortgages satisfying certain criteria. The target for lending to weaker sections continues to be at 10% of adjusted net bank credit. At year-end fiscal 2017, ICICI Bank’s priority sector lending was Rs. 1,490.8 billion. As prescribed in the Reserve Bank of India guidelines, the Bank’s priority sector lending compliance was computed on quarterly average basis for fiscal 2017. Total average priority sector lending was Rs. 1,399.4 billion constituting 39.9% of adjusted net bank credit against the requirement of 40.0% of adjusted net bank credit. The average lending to the agriculture sector was Rs. 547.4 billion constituting 15.6% of adjusted net bank credit against the requirement of 18.0% of adjusted net bank credit. The average advances to weaker sections were Rs. 220.9 billion constituting 6.3% of

adjusted net bank credit against the requirement of 10.0% of adjusted net bank credit. Average lending to small and marginal farmers was Rs. 142.2 billion constituting 4.1% of adjusted net bank credit against the requirement of 8.0% of adjusted net bank credit. The average lending to micro enterprises was Rs. 241.2 billion constituting 6.9% of adjusted net bank credit against the requirement of 7.5% of adjusted net bank credit. The average lending to non-corporate farmers was Rs. 300.9 billion constituting 8.6% of adjusted net bank credit against the requirement of 11.7% of adjusted net bank credit.

The Reserve Bank of India has from time to time issued guidelines on priority sector lending requirements that restrict the ability of banks to meet the directed lending obligations through lending to specialized financial intermediaries, specified criteria to be fulfilled for investments by banks in securitized assets and outright purchases of loans and assignments to be eligible for classification as priority sector lending and regulate the interest rates charged to ultimate borrowers by the originating entities in such transactions. In September 2013, the Reserve Bank of India set up a committee on comprehensive financial services for small businesses and low income households which, among other recommendations, proposed a new methodology for computation of priority sector targets based on district-level credit penetration and other criteria. This recommendation has not been implemented thus far.

Any shortfall in meeting the priority sector lending requirements may be required to be invested at any time, at the Reserve Bank of India’s request, in Government schemes that yield low returns, determined depending on the prevailing bank rate and on the level of shortfall, thereby impacting our profitability. The aggregate amount of funding required by such schemes is drawn from banks that have shortfalls in achievement of their priority sector lending targets, with the amounts drawn from each bank determined by the Reserve Bank of India. At year-end fiscal 2017 our total investments in such schemes on account of past shortfalls in achieving the required level of priority sector lending were Rs. 241.1 billion. In May 2014, the Reserve Bank of India issued guidelines allowing banks to include the outstanding mandated investments in Government schemes at March 31 of the fiscal year to be treated as part of indirect agriculture and count towards overall priority sector target achievement. Investments at March 31 of the preceding year would be included in the adjusted net bank credit which forms the base for computation of the priority sector and sub-segment lending requirements. These changes were made effective fiscal 2014. The Reserve Bank of India has proposed a scheme to sell and purchase priority sector lending certificates among banks in the event of excess/shortfall in meeting priority sector targets, which may help in reducing the shortfall in priority sector lending. However, this would depend on the availability of such certificates for trading. Our investments in Government schemes are expected to increase in view of the continuing shortfall in agriculture lending sub-targets and weaker section loans. See also “ Supervision and Regulation—Directed lending ”.

As a result of priority sector lending requirements, we may experience a higher level of non-performing assets in our directed lending portfolio, particularly due to loans to the agricultural sector and small enterprises, where we are less able to control the portfolio quality and where economic difficulties are likely to affect our borrowers more severely. The Bank’s gross non-performing assets in the priority sector loan portfolio were 2.3% in fiscal 2014, 2.1% in fiscal 2015 and 2.2% in fiscal 2016 and fiscal 2017. Recently, some states in India have announced schemes for waiver of loans taken by farmers. While the cost of such schemes is borne by the state governments, such schemes or borrower expectations of such schemes may result in higher delinquencies in our agricultural lending portfolio. Any future changes by the Reserve Bank of India to the directed lending norms may result in our continued inability to meet the priority sector lending requirements as well as require us to increase our lending to relatively more risky segments and may result in an increase in non-performing loans.

In addition to the directed lending requirements, the Reserve Bank of India has mandated banks in India to have a financial inclusion plan for expanding banking services to rural and unbanked centers and to customers who currently do not have access to banking services. Further, since August 2014, the Indian government has launched a financial inclusion mission which involves opening a bank account for every household along with credit and insurance facilities. The expansion into these markets involves significant investments and recurring costs. The profitability of these operations depends on our ability to generate business volumes in these centers and from these customers, and the level of non-performing loans in the portfolio of loans to such customers.

We have seen a significant increase in our branch network over the last few years and any inability to use these branches productively or substantial delays in achieving desired levels of productivity may have an adverse impact on our growth and profitability.

The branch network of ICICI Bank in India has increased from 3,100 branches at year-end fiscal 2013 to 4,850 branches at year-end fiscal 2017. See also “— We may seek opportunities for growth through acquisitions, divest our existing businesses, or be required to undertake mergers by the Reserve Bank of India and could face integration and other acquisitions risks ”. We have also substantially scaled up our branch network in rural and

semi-urban areas and have also established low-cost branches in centers in the country having no bank presence. Our new branches typically operate at lower productivity levels, as compared to our existing branches. Our operating performance depends also on the productivity of our employees. Any inability to achieve or substantial delays in achieving desired levels of productivity would have an adverse impact on our growth and profitability and the price of our equity shares and ADSs .

We are subject to capital adequacy and liquidity requirements stipulated by the Reserve Bank of India, including Basel III, and any inability to maintain adequate capital or liquidity due to changes in regulations, a lack of access to capital markets, or otherwise may impact our ability to grow and support our businesses.

With effect from April 1, 2013, banks in India commenced implementation of the Basel III capital adequacy framework as stipulated by the Reserve Bank of India. The Basel III guidelines, among other things, establish common equity Tier 1 as a new tier of capital; impose a minimum common equity Tier 1 risk-based capital ratio of 5.5% and a minimum Tier 1 risk-based capital ratio of 7.0% while retaining the minimum total risk-based capital ratio of 9.0%; require banks to maintain a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets above the minimum requirements to avoid restrictions on capital distributions and discretionary bonus payments; establish new eligibility criteria for capital instruments in each tier of regulatory capital; require more stringent adjustments to and deductions from regulatory capital; provide for more limited recognition of minority interests in the regulatory capital of a consolidated banking group; impose a 4.5% Basel III leverage ratio of Tier 1 capital to exposure during a parallel run period from 2013 to 2017; and modify the Reserve Bank of India’s Basel II guidelines with respect to credit risk, including counterparty credit risk and credit risk mitigation, and market risk. The guidelines are to be fully implemented by year-end fiscal 2019. Applying the Basel III guidelines, our capital ratios on a consolidated basis at year-end fiscal 2017 were: common equity Tier 1 risk-based capital ratio of 13.8%; Tier 1 risk-based capital ratio of 14.4%; and total risk-based capital ratio of 17.3%.

The capital regulations continue to evolve, both globally and in India. The Reserve Bank of India requires additional capital to be held by banks as a systemic buffer. For instance, in July 2014, the Reserve Bank of India issued guidelines requiring additional common equity Tier 1 capital requirements ranging from 0.2% to 0.8% of risk-weighted assets for domestic banks that are identified as systemically important. The systemic importance of a bank would be determined based on the size, inter-connectedness, substitutability and complexity of the bank, with a larger weightage given to size. We were declared a systemically important bank in India by the Reserve Bank of India in August 2015 and placed in the first bucket which requires us to maintain additional common equity Tier 1 capital of 0.2% in a phased manner from April 1, 2016. Further, the Reserve Bank of India also released guidelines on implementation of counter-cyclical capital buffers which propose higher capital requirements for banks, ranging from 0% to 2.5% of risk-weighted assets, during periods of high economic growth. The capital requirement would be determined based on certain triggers such as deviation of long-term average credit-to-GDP ratio and other indicators. While these guidelines are already effective, the Reserve Bank of India has stated that current economic conditions do not warrant activation of the counter-cyclical capital buffer. In addition, with the approval of the Reserve Bank of India, banks in India may migrate to advanced approaches for calculating risk-based capital requirements in the medium term. The Reserve Bank of India has increased the risk weight on unrated exposures to corporates and infrastructure financing non-banking finance companies from 100.0% to 150.0% if the aggregate exposure of the banking system exceeds Rs. 2.0 billion. This is effective from June 30, 2017. Such regulatory changes and evolving regulations may impact the amount of capital that we are required to hold. Our ability to grow our business and execute our strategy is dependent on our level of capitalization and we typically raise resources from the capital markets to meet our capital requirements.

In December 2013, the Reserve Bank of India issued guidelines on stress testing according to which banks have to carry out stress tests for credit risk and market risk to assess their ability to withstand shocks. Banks are classified into three categories based on size of risk-weighted assets and banks with risk-weighted assets of more than Rs. 2,000.0 billion are required to carry out complex and severe stress testing.

In June 2014, the Reserve Bank of India released guidelines on liquidity coverage ratio requirements under the Basel III liquidity framework. These guidelines require banks to maintain and report the Basel III liquidity coverage ratio, which is a ratio of the stock of high quality liquid assets and total net cash outflows over the next 30 calendar days. The Reserve Bank of India has also defined categories of assets qualifying as high quality liquid assets and mandated a minimum liquidity coverage ratio of 60.0% from January 1, 2015, which would be increased in a phased manner to a minimum of 100.0% from January 1, 2019. The Reserve Bank of India has also issued a leverage ratio framework which is effective from April 1, 2015 and is measured as the ratio of a bank’s Tier 1 capital and total exposure. Further, the Reserve Bank of India has issued draft guidelines on the net stable funding ratio for banks which is expected to be applicable from January 1, 2018 and would require

banks to maintain sufficient funds that are considered as reliable to cover the liquidity requirements and asset maturities coming up over the next one year on an ongoing basis. These requirements together with the existing liquidity and cash reserve requirements may result in Indian banks, including us, holding higher amounts of liquidity, thereby impacting profitability.

Any reduction in our regulatory capital ratios, increase in liquidity requirements applicable to us on account of regulatory changes or otherwise, changes in the composition of liquidity and any inability to access capital markets may limit our ability to grow our business, impact our profitability and our future performance and strategy.

Our risk profile is linked to the Indian economy and the banking and financial markets in India which are still evolving.

Our credit risk may be higher than the credit risk of banks in some developed economies. Unlike several developed economies, a nation-wide credit bureau only became operational in India in 2000. This may limit the information available to us about the credit history of our borrowers, especially individuals and small businesses. In addition, the credit risk of our borrowers is often higher than borrowers in more developed economies due to the evolving Indian regulatory, political, economic and industrial environment. The directed lending norms of the Reserve Bank of India require us to lend a certain proportion of our loans to “priority sectors”, including agriculture and small enterprises, where we are less able to control the portfolio quality and where economic difficulties are likely to affect our borrowers more severely. Any shortfall may be required to be allocated to investments yielding sub-market returns. See also “— We are subject to the directed lending requirements of the Reserve Bank of India, and any shortfall in meeting these requirements may be required to be invested in Government schemes that yield low returns, thereby impacting our profitability. We may also experience a higher level of non-performing assets in our directed lending portfolio, which could adversely impact the quality of our loan portfolio, our business and the price of our equity shares and ADSs ” and “ Business—Loan Portfolio—Directed Lending ”. Several of our corporate borrowers have suffered from low profitability because of increased competition from economic liberalization, a sharp decline in commodity prices, high debt burden and high interest rates in the Indian economy, and other factors. An economic slowdown and a general decline in business activity in India could impose further stress on these borrowers’ financial soundness and profitability and thus expose us to increased credit risk. For instance, developments in the Indian economy have led to a rise in non-performing and restructured assets of Indian banks, including us, since fiscal 2014. Such conditions may lead to an increase in the level of our non-performing assets and there could be an adverse impact on our business, our future financial performance, our stockholders’ equity and the price of our equity shares and ADSs.

In addition to credit risks, we also face additional risks as compared with banks in developed economies. We pursue our banking, insurance and other activities in India in a developing economy with all of the risks that come with such an economy. Our activities in India are widespread and diverse and involve employees, contractors, counterparties and customers with widely varying levels of education, financial sophistication and wealth. Although we seek to implement policies and procedures to reduce and manage marketplace risks as well as risks within our own organization, some risks remain inherent in doing business in a large, developing country. We cannot eliminate these marketplace and operational risks, which may lead to legal or regulatory actions, negative publicity or other developments that could reduce our profitability. In the aftermath of the financial crisis, regulatory scrutiny of these risks is increasing. See also “— The value of our collateral may decrease or we may experience delays in enforcing our collateral when borrowers default on their obligations to us which may result in failure to recover the expected value of collateral security exposing us to a potential loss ”.

The enhanced supervisory and compliance environment in the financial sector increases the risk of regulatory action, whether formal or informal. Following the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past.

We are subject to a wide variety of banking, insurance and financial services laws, regulations and regulatory policies and a large number of regulatory and enforcement authorities in each of the jurisdictions in which we operate. Since the global financial crisis, regulators in India and in the other jurisdictions in which we operate have intensified their review, supervision and scrutiny of many financial institutions, including us. In the aftermath of the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past, in a range of areas. This increased review and scrutiny or any changes in the existing regulatory supervision framework, increases the possibility that we will face adverse legal or regulatory actions. The Reserve Bank of India and other regulators regularly review our operations, and there can be no guarantee that all regulators will agree with our internal assessments of asset quality, provisions,

risk management, capital adequacy and management functioning, other measures of the safety and soundness of our operations or compliance with applicable laws, regulations, accounting and taxation norms or regulatory policies. See also “ —If regulators continue to impose increasingly stringent requirements regarding non-performing loans and provisioning for such loans, or if the provisions for such loans otherwise increase, our business will suffer ”. Regulators may find that we are not in compliance with applicable laws, regulations, accounting and taxation norms or regulatory policies, or with the regulators’ revised interpretations of such laws, regulations or regulatory policies, and may take formal or informal actions against us. Such formal or informal actions might force us to make additional provisions for our non-performing assets or otherwise, divest our assets, adopt new compliance programs or policies, remove personnel, reduce dividend or executive compensation or undertake other changes to our business operations. Any of these changes, if required, could reduce our profitability by restricting our operations, imposing new costs or harming our reputation. In April 2017, the Reserve Bank of India directed banks to make disclosures in the notes to accounts to the financial statements where divergences in asset classification and provisioning consequent to Reserve Bank of India’s annual supervisory assessment process have exceeded a specified threshold. See also “— The regulatory environment for financial institutions is facing unprecedented change in the post-financial crisis environment ” and “ Supervision and Regulation” .

Our banking subsidiaries in the United Kingdom and Canada have in the past focused primarily on leveraging their deposit franchises in these markets to extend financing to Indian companies for their operations in India and globally, including the financing of overseas acquisitions by Indian companies through structured transactions. In view of regulatory limitations on cross-border financing of this nature, these subsidiaries have experienced a reduction in their business, impacting their profitability and resulting in a sharp reduction in the return on the capital invested in these businesses. While both these subsidiaries are focused on growing their business within the current regulatory framework, the opportunities to do so may be limited. Further, while both these subsidiaries are focused on optimizing their capital base and have repatriated capital and made dividend payments to ICICI Bank in the recent past, such initiatives are subject to regulatory approvals. There can be no assurance regarding the timing or grant of such approvals in the future. Our overseas branches are also subject to respective local regulatory requirements, including any requirements related to liquidity, capital and asset classification and provisioning.

In addition to oversight by the Reserve Bank of India, our insurance subsidiaries are also subject to extensive regulation and supervision by India’s insurance regulators. The Insurance Regulatory and Development Authority of India has the authority to modify and interpret regulations regarding the insurance industry, including regulations governing products, selling commissions, solvency margins and reserving, which can lead to additional costs or restrictions on our insurance subsidiaries’ activities. Similarly, our asset management subsidiary is subject to supervision and regulation by the Securities and Exchange Board of India. There can be no assurance that increase in regulatory scrutiny of our subsidiaries and stringent requirements, including additional disclosures, will not have a material adverse impact on the Bank.

Failure to comply with applicable regulations in various jurisdictions, including unauthorized actions by employees, representatives, agents and third parties, suspected or perceived failures and media reports, and ensuing inquiries or investigations by regulatory and enforcement authorities, has resulted, and may result in the future, in regulatory actions, including financial penalties and restrictions on or suspension of the related business operations. Following the release on the Internet in March 2013 of videos forming part of a sting operation on banks and insurance companies in India that purported to show the Bank’s frontline branch employees engaging in conversations that would violate our Group’s Code of Business Conduct and Ethics and could have, if any transactions had been consummated, led to violations of anti-money laundering and ‘know-your-customer’ norms, the Reserve Bank of India undertook investigations at ICICI Bank and over 30 other banks in India. While the Reserve Bank of India’s investigations did not reveal any prima facie evidence of money laundering, the Reserve Bank of India imposed an aggregate penalty of Rs. 665 million on 31 Indian banks, including Rs. 10 million on ICICI Bank, for instances of violation of applicable regulations, which we have paid. A penalty of Rs. 1.4 million was also imposed on the Bank in February 2015 by the Financial Intelligence Unit, India, for failure in reporting the attempted suspicious transactions to which the above sting operations pertained. The Bank had filed an appeal against the penalty with the Appellate Tribunal. In June 2017, the Appellate Tribunal ruled that the penalty was not sustainable. The Tribunal asked the appellant banks to be careful and report such matters in future.

In addition, a failure to comply with the applicable regulations in various jurisdictions by our employees, representatives, agents and third-party service providers either in or outside the course of their services, or suspected or perceived failures by them, may result in inquiries or investigations by regulatory and enforcement authorities and in regulatory or enforcement action against either us, or such employees, representatives, agents and third-party service providers. Such actions may impact our reputation, result in adverse media reports, lead to increased or enhanced regulatory or supervisory concerns, cause us to incur additional costs, penalties, claims and expenses or impact adversely our ability to conduct business.

If we fail to manage our legal and regulatory risk in the many jurisdictions in which we operate, our business could suffer, our reputation could be harmed and we would be subject to additional legal and regulatory risks. This could, in turn, increase the size and number of claims and damages asserted against us and/or subject us to regulatory investigations, enforcement actions or other proceedings, or lead to increased supervisory concerns. We may also be required to spend additional time and resources on remedial measures, which could have an adverse effect on our business.

Despite our best efforts to comply with all applicable regulations, there are a number of risks that cannot be completely controlled. Our international expansion has led to increased legal and regulatory risks. Regulators in every jurisdiction in which we operate or have listed our securities have the power to restrict our operations, stipulate higher capital and liquidity requirements or bring administrative or judicial proceedings against us (or our employees, representatives, agents and third-party service providers), which could result, among other things, in suspension or revocation of one or more of our licenses, cease and desist orders, fines, civil penalties, criminal penalties or other disciplinary action which could materially harm our reputation, results of operations and financial condition.

We cannot predict the timing or form of any current or future regulatory or law enforcement initiatives, which are increasingly common for international banks and financial institutions, but we would expect to cooperate with any such regulatory investigation or proceeding.

The value of our collateral may decrease or we may experience delays in enforcing our collateral when borrowers default on their obligations to us which may result in failure to recover the expected value of collateral security exposing us to a potential loss.

A substantial portion of our loans to corporate and retail customers is secured by collateral. See also “ Business—Classification of Loans—Non-Performing Asset Strategy ”. Changes in asset prices may cause the value of our collateral to decline, and we may not be able to realize the full value of our collateral as a result of delays in bankruptcy and foreclosure proceedings, delays in the creation of security interests, defects or deficiencies in the perfection of collateral (including due to inability to obtain approvals that may be required from various persons, agencies or authorities), fraudulent transfers by borrowers and other factors, including depreciation in the value of the collateral and illiquid market for disposal of and volatility in the market prices for the collateral, current legislative provisions or changes thereto and past or future judicial pronouncements.

In India, foreclosure on collateral consisting of property can be undertaken directly by lenders by fulfilling certain procedures and requirements (unless challenged in courts of law) or otherwise by a written petition to an Indian court or tribunal. An application, when made (or a legal challenge to the foreclosure undertaken directly), may be subject to delays or administrative requirements that may result in, or be accompanied by, a decrease in the value of collateral. These delays can last for several years and might lead to deterioration in the physical condition or market value of the collateral. In the event a corporate borrower is in financial difficulty and unable to sustain itself, it may opt for the process of voluntary winding up. If a company becomes a “sick unit” (as defined under Indian law, which provides for a unit to be so categorized based on the extent of its accumulated losses relative to its stockholders’ equity), foreclosure and enforceability of collateral is stayed. In some cases, we may repossess collateral in lieu of principal and interest dues but may experience delays in liquidating the collateral. While the Indian parliament has approved legislation introducing a new Insolvency and Bankruptcy Code, there are uncertainties in respect of its impact on recovery of dues by lenders. Any delays caused by the lack of infrastructure, including information utilities, in reaching a resolution within the assigned timelines may increase the risk of failure and the company going into liquidation under the legislation.

In addition, for collateral we hold in jurisdictions outside India, the applicable laws and regulations in such jurisdictions may impact our ability to foreclose on collateral and realize its value. Failure to recover the expected value of collateral could expose us to potential losses, which could adversely affect our future financial performance, our stockholders’ equity and the price of our equity shares and ADSs.

We depend on the accuracy and completeness of information about customers and counterparties.

In deciding whether to extend credit or enter into other transactions with customers and counterparties, we may rely on information furnished to us by or on behalf of customers and counterparties, including financial statements and other financial information. We may also rely on certain representations as to the accuracy and completeness of that information and, with respect to financial statements, on reports of their independent auditors. For example, in deciding whether to extend credit, we may assume that a customer’s audited financial statements conform to generally accepted accounting principles and present fairly, in all material respects, the

financial condition, results of operations and cash flows of the customer. Our financial condition and results of operations could be negatively affected by relying on financial statements that do not comply with generally accepted accounting principles or other information that is materially misleading. In addition, unlike several developed economies, a nationwide credit bureau has only recently built up its database in India. This may affect the quality of information available to us about the credit history of our borrowers, especially individuals and small businesses. As a result, our ability to effectively manage our credit risk may be adversely affected.

Commission, exchange and brokerage income and profit on foreign exchange transactions are important elements of our profitability, and regulatory changes and market conditions could cause these income streams to decline and adversely impact our financial performance.

We earn commission, exchange and brokerage income from a variety of activities, including loan processing, syndication and advisory services for corporate clients with respect to their acquisition and project financing, distribution of retail investment and insurance products, transaction banking and retail credit products. Our commission, exchange and brokerage income is therefore impacted by the level of corporate activity including new financing proposals, the demand for retail financial products and the overall level of economic and trade activity. Our commission, exchange and brokerage income is also impacted by applicable regulations governing various products and segments of financial services and changes in these regulations may adversely impact our ability to grow in this area. For example, in May 2014, the Reserve Bank of India directed banks to remove foreclosure charges on floating rate term loans given to individual borrowers and were prohibited from levying a penalty for non-maintenance of minimum balance in inoperative accounts. The securities regulator has issued regulations restricting charges that may be levied on depositary accounts. The profit on foreign exchange transactions is dependent on foreign exchange market conditions and the risk management strategies of corporate clients. Volatile market conditions may also have an adverse impact on mergers and acquisitions activity by Indian companies, affecting our fee and other incomes related to such activity. Since fiscal 2012, we have witnessed a moderation in growth in our commission, exchange and brokerage income, primarily due to the decline in corporate investment activity and new financing proposals. Further, in February 2017, the Reserve Bank of India released a draft circular on rationalization of Merchant Discount Rate for debit card transactions. The draft circular seeks a shift from the present slab-rate based Merchant Discount Rate on transaction value to merchant turnover based Merchant Discount Rate structure, for which merchants have been suitably categorized. These and various factors could adversely impact our fee income streams in the future and adversely affect our financial performance.

Our international operations increase the complexity of the risks that we face.

Our international profile in multiple jurisdictions exposes us to a variety of regulatory and business challenges and risks, including cross-cultural risk and has increased the complexity of our risks in a number of areas including price risks, currency risks, interest rate risks, compliance risk, regulatory and reputational risk and operational risk. In the aftermath of the financial crisis and in light of enhanced regulations in many countries, we expect to face additional scrutiny in all of these areas and in the management of our international operations. There could be risks arising from political changes in the jurisdictions in which we operate, such as the election by a majority of voters in the United Kingdom to withdraw from the European Union in a national referendum in June 2016. We also face risks arising from our ability to manage inconsistent legal and regulatory requirements in the multiple jurisdictions in which we operate. Our businesses are subject to changes in legal and regulatory requirements and it may not be possible to predict the timing or nature of such changes. Business opportunities in these jurisdictions will also determine the growth in our operations.

The loan portfolio of our international branches and subsidiaries includes foreign currency loans to Indian companies for their Indian operations (as permitted by regulation) as well as for their overseas ventures, including cross-border acquisitions. This exposes us to specific additional risks including the failure of the acquired entities to perform as expected, and our inexperience in various aspects of the economic and legal framework in overseas markets. Regulatory changes globally and in specific markets, including increased regulatory oversight following the global financial crisis, may impact our ability to execute our strategy and deliver returns on capital invested in our international subsidiaries. Our banking subsidiaries in the United Kingdom and Canada have in the past focused primarily on leveraging their deposit franchises in these markets to extend financing to Indian companies for their operations in India and globally, including the financing of overseas acquisitions by Indian companies through structured transactions. In view of the position taken by these subsidiaries’ respective regulators in connection with cross-border risk and exposure concentration, these subsidiaries have reduced their business volumes, resulting in a high level of capital relative to assets in ICICI Bank Canada and impacting the return on the capital invested by ICICI Bank in these subsidiaries. While these subsidiaries are focused on growing their business within the current regulatory framework, the opportunities to do so may be limited. Further, while we are seeking to rationalize the capital invested in our overseas banking

subsidiaries and these subsidiaries have repatriated a part of their excess capital to ICICI Bank, there can be no assurance that we will be able to achieve further capital rationalization through repatriation or otherwise. Further, recent global developments including decline in crude oil prices and the United Kingdom’s decision to exit from the European Union are expected to slow down economic growth in Canada and the United Kingdom, which in turn could impact the business of our banking subsidiaries in these countries. See also “— The enhanced supervisory and compliance environment in the financial sector increases the risk of regulatory action, whether formal or informal. Following the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past ” and “— The regulatory environment for financial institutions is facing unprecedented change in the post-financial crisis environment ”. Our overseas branches and banking subsidiaries undertake select local banking businesses, including lending to multinational and local corporations, small businesses, property backed lending and insured mortgages, and in the event of these corporations being impacted by global and local economic conditions it could have an adverse impact on our business. They have also made investments in bonds, certificates of deposits, mortgage backed securities, treasury bills, credit derivatives and asset-backed commercial paper. The global financial and economic crisis resulted in mark-to-market and realized losses on our overseas and other subsidiaries’ investment and derivative portfolios, increased the regulatory scrutiny of our international operations, constrained our international debt capital market borrowings and increased our cost of funding. If we are unable to manage these risks, our business would be adversely affected.

Our funding is primarily short-term and if depositors do not roll over deposited funds upon maturity, our business could be adversely affected.

Most of our incremental funding requirements are met through short-term funding sources, primarily in the form of deposits including deposits from corporate customers and interbank deposits. Our customer deposits generally have a maturity of less than one year. However, a large portion of our assets have medium-or long-term maturities, creating the potential for funding mismatches. For example, our project finance loans typically have longer-term maturities compared to our funding profile. Our ability to raise fresh deposits and grow our deposit base depends in part on our ability to expand our network of branches, which in the past required the prior approval of the Reserve Bank of India. We have recently significantly expanded our branch network pursuant to the Reserve Bank of India’s authorizations for establishing new branches, and the Reserve Bank of India has also permitted banks to freely open new branches subject to certain conditions since September 2013. “ Supervision and Regulation— Regulations Relating to the Opening of Branches ”. Our new branches typically operate at lower efficiency levels, as compared to our existing branches, and although we intend to increase their efficiency over time, any inability to use these branches productively, or substantial delays in achieving desired levels of productivity, may have an impact on our ability to grow our deposit base to the desired extent.

Negative rumors have been previously circulated about our financial position which resulted in concerns being expressed by depositors and higher than normal withdrawal levels for a few days. Furthermore, a part of our loan and investment portfolio, consisting primarily of the loan and investment portfolios of our international branches and subsidiaries is denominated in foreign currencies, including the U.S. dollar. Our international branches are primarily funded by debt capital market issuances and syndicated/bilateral loans, while our international subsidiaries generally raise deposits in their local markets. We have certain borrowings that would be affected by a one or two notch downgrade of the Bank’s current credit rating. These borrowings amount to approximately 3.0% of our total borrowings at year-end fiscal 2017. If an international credit rating agency downgrades the Bank’s credit rating by one or two notches, we would be required to pay an increased interest rate on certain borrowings, and for certain borrowings, we would be required to re-negotiate a new interest rate with our lenders. If we are not able to reach an agreement for an interest rate with a lender, the lender could require us to prepay the outstanding principal amount of the loan. Volatility in the international debt markets may constrain our international capital market borrowings. There can be no assurance that our international branches and subsidiaries will be able to obtain funding from the international debt markets or other sources in a timely manner on terms acceptable to them or at all. This may adversely impact our ability to replace maturing borrowings and fund new assets. In addition, borrowers who have taken foreign currency loans from us may face challenges in meeting their repayment obligations on account of market conditions and currency movements. See also “— Risks Relating to India and Other Economic and Market Risks—Financial instability in other countries, particularly emerging market countries and countries where we have established operations, could adversely affect our business and the price of our equity shares and ADSs ”, “— Risks Relating to India and Other Economic and Market Risks—Financial difficulty and other problems in the Indian financial system in India could adversely affect our business and the price of our equity shares and ADSs ” and “ —Our international operations increase the complexity of the risks that we face ”.

The regulatory environment for financial institutions is facing unprecedented change in the post-financial crisis environment.

The global financial crisis has led to significant and unprecedented changes in the laws, regulations and regulatory policies of India and the other jurisdictions in which we operate. Changes in laws, regulations or regulatory policies, including changes in the interpretation or application of such laws, regulations and regulatory policies, may adversely affect the products and services we offer, the value of our assets or the collateral available for our loans or our business in general. Recent regulatory changes as well as changes currently under discussion, such as changes with respect to Basel III risk-based and leverage capital requirements, Basel III liquidity requirements; restrictions on cross-border capital flows; enhanced emphasis on local lending obligations in overseas jurisdictions; changes in directed lending regulations in India; using national benchmark indices for pricing bank products; concentration of large exposures in banks and collateral management; continuous licensing of universal banks; and discussions on management compensation, board governance, consumer protection and risk management, among other areas, are expected to have an impact on our business and our future strategy. These changes could require us to reduce or increase our business in specific segments, impact our overall growth and impact our return on capital. For instance, our wholly owned banking subsidiaries in the United Kingdom and Canada reduced their business volumes after fiscal 2009 in response to the changes in the regulatory environment, which has impacted their growth and profitability. While both these subsidiaries are focused on growing their business within the current regulatory framework, the opportunities to do so may be limited. Further, while both these subsidiaries are focused on optimizing their capital base and have repatriated capital and made dividend payments to ICICI Bank in the recent past, such measures are subject to regulatory approvals. There can be no assurance regarding the timing or grant of such approvals in the future. The Reserve Bank of India has moved to a risk-based supervision approach for Indian banks, including us, and may require banks to hold additional capital over and above the minimum regulatory requirements based on its assessment of risks for individual banks.

Changes in laws, regulations and regulatory policies, or the interpretation or application thereof, have and we expect will continue to lead to enhanced regulatory oversight and scrutiny and increased compliance costs. In the aftermath of the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past. This increased scrutiny increases the possibility that we will face adverse legal or regulatory actions. The Reserve Bank of India and other regulators regularly review our operations, and there can be no guarantee that any regulator will agree with our internal assessments of asset quality, provisions, risk management, capital adequacy, management functioning or other measures of the safety and soundness of our operations. See also “If regulators continue to impose increasingly stringent requirements regarding non-performing loans and provisioning for such loans, or if the provisions for such loans otherwise increase, our business will suffer”. In addition, regulators may find that we are not in compliance with applicable laws, regulations or regulatory policies, or with the regulators’ revised interpretations of such laws, regulations or regulatory policies, and may take formal or informal actions against us. Our ability to predict future legal or regulatory changes is limited and we may face enhanced legal or regulatory burdens without advance notice. For example, the Reserve Bank of India, in its guidelines for new private sector banking licenses issued in February 2013, has mandated new banks pursuant to the issuance of such licenses, to be set up under a financial holding company structure. In future, such requirements may be extended to existing banks in India, including us. Also, the Reserve Bank of India has released a discussion paper on a new banking structure in India. See also “ Overview of the Indian Financial Sector—Structural Reforms ”. Any such regulatory or structural changes may result in increased expenses, operational restrictions, increased competition or revisions to our business operations, which may reduce our profitability or force us to forego potentially profitable business opportunities. The Reserve Bank of India’s scheme for Prompt Corrective Action on banks with high level of non-performing loans has been effective since December 2002. In April 2017, the Reserve Bank of India revised the framework and included indicators to be tracked like capital adequacy, asset quality, profitability and leverage with specified risk thresholds that would result in invocation of prompt corrective action. The revised framework stipulates actions like restriction on dividend distribution/remittance of profits, restriction on branch expansion; domestic and/or overseas, higher provisions as part of the coverage regime, and restriction on management compensation and directors’ fees. At year-end fiscal 2017, the Bank’s financial indicators did not breach the risk thresholds prescribed by the Reserve Bank of India. There can be no assurance that we will always remain within the thresholds prescribed by the Reserve Bank of India in the future. See also “— The enhanced supervisory and compliance environment in the financial sector increases the risk of regulatory action, whether formal or informal. Following the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past ”.

Our inability to effectively manage credit, market and liquidity risk and inaccuracy of our valuation models and accounting estimates may have an adverse effect on our earnings, capitalization, credit ratings and cost of funds.

Our risk management strategies may not be effective because in a difficult or less liquid market environment other market participants may be attempting to use the same or similar strategies to deal with difficult market conditions. In such circumstances, it may be difficult for us to reduce our risk positions due to the activity of such other market participants. Our derivatives businesses may expose us to unexpected market, credit and operational risks that could cause us to suffer unexpected losses or enhanced regulatory scrutiny. Severe declines in asset values, unanticipated credit events, or unforeseen circumstances that may cause previously uncorrelated factors to become correlated may create losses resulting from risks not appropriately taken into account in the development, structuring or pricing of a derivative instrument. In addition, many derivative transactions are not cleared and settled through a central clearing house or exchange, and they may not always be confirmed or settled by counterparties on a timely basis. In these situations, we are subject to heightened credit and operational risk, and in the event of a default, we may find the contract more difficult to enforce. Further, as new and more complex derivative products are created, disputes regarding the terms or the settlement procedures of the contracts could arise, which could force us to incur unexpected costs, including transaction and legal costs, and impair our ability to manage effectively our risk exposure to these products. Many of our hedging strategies and other risk management techniques have a basis in historic market behavior, and all such strategies and techniques are based to some degree on management’s subjective judgment. To the extent any of the instruments and strategies we use to hedge or otherwise manage our exposure to market or credit risk are not effective, we may not be able to mitigate effectively our risk exposures in particular market environments or against particular types of risk. Our balance sheet growth is dependent upon economic conditions, as well as upon our ability to securitize, sell, purchase or syndicate particular loans or loan portfolios. Our trading revenues and interest rate risk are dependent upon our ability to properly identify, and mark-to-market, changes in the value of financial instruments caused by changes in market prices or rates. Our earnings are dependent upon the effectiveness of our management of migrations in credit quality and risk concentrations, the accuracy of our valuation models and our critical accounting estimates and the adequacy of our allowances for loan losses.

To the extent our assessments, assumptions or estimates prove inaccurate or not predictive of actual results, we could suffer higher than anticipated losses and enhanced regulatory scrutiny. The successful management of credit, market and operational risk is an important consideration in managing our liquidity risk because it affects the evaluation of our credit ratings by domestic and international rating agencies. Rating agencies may reduce or indicate their intention to reduce the ratings at any time. See also “— Risks Relating to India and Other Economic and Market Risks—Any downgrade of India’s debt rating by an international rating agency could adversely affect our business, our liquidity and the price of our equity shares and ADSs ”. The rating agencies can also decide to withdraw their ratings altogether, which may have the same effect as a reduction in our ratings. Any reduction in our ratings (or withdrawal of ratings) may increase our borrowing costs, limit our access to capital markets and adversely affect our ability to sell or market our products, engage in business transactions particularly longer-term, and derivatives transactions, or retain our customers. Conditions in the international and Indian debt markets may adversely impact our access to financing and liquidity. This, in turn, could reduce our liquidity and negatively impact our operating results and financial condition. For more information relating to our ratings, see also “ Business—Risk Management—Quantitative and Qualitative Disclosures about Market Risk—Liquidity Risk ”.

Negative publicity could damage our reputation and adversely impact our business and financial results and the price of our equity shares and ADSs.

Reputation risk, or the risk to our business, earnings and capital from negative publicity, is inherent in our business. The reputation of the financial services industry in general has been closely monitored as a result of the financial crisis and other matters affecting the financial services industry. Negative public opinion about the financial services industry generally or us specifically could adversely affect our ability to keep and attract customers, and expose us to litigation and regulatory action. Negative publicity can result from our actual or alleged conduct in any number of activities, including lending practices and specific credit exposures, the level of non-performing loans, corporate governance, regulatory compliance, mergers and acquisitions, and related disclosure, sharing or inadequate protection of customer information, and actions taken by government, regulators and community organizations in response to that conduct. Although we take steps to minimize reputation risk in dealing with customers and other constituencies, we, as a large financial services organization are inherently exposed to this risk. Our subsidiaries’ businesses include mutual fund, portfolio and private equity fund management, which are exposed to various risks including diminution in value of investments and inadequate liquidity of the investments. We also distribute products of our insurance, asset management and private equity subsidiaries. Investors in these funds and schemes may allege mismanagement or weak fund management as well as mis-selling and conflicts of interest which may impact our overall reputation as a financial services group and may require us to support these businesses with liquidity and may result in a

reduction in business volumes and revenues from these businesses. We are also exposed to the risk of litigation by customers across our businesses.

We may seek opportunities for growth through acquisitions, divest our existing businesses, or be required to undertake mergers by the Reserve Bank of India and could face integration and other acquisitions risks.

We may seek opportunities for growth through acquisitions or be required to undertake mergers mandated by the Reserve Bank of India under its statutory powers. We have undertaken mergers and acquisitions in the past. Most recently, the Bank of Rajasthan, a private sector bank, merged with us effective August 12, 2010. In the past, the Reserve Bank of India has ordered mergers of weak banks with other banks primarily in the interest of depositors of the weak banks. More recently, the Indian government has indicated that public sector banks should pursue consolidation to create a smaller number of banks that are individually large in scale. We may in the future examine and seek opportunities for acquisitions in countries where we currently operate. Our non-banking subsidiaries in India may also undertake mergers, acquisitions and takeovers. Any future acquisitions or mergers or takeovers, both Indian or international, may involve a number of risks, including the possibility of a deterioration of asset quality, financial impact of employee related liabilities, diversion of our management’s attention required to integrate the acquired business and the failure to retain key acquired personnel and clients, leverage synergies or rationalize operations, or develop the skills required for new businesses and markets, or unknown and known liabilities including any ongoing litigation, claims or disputes concerning such acquisition, merger, its shareholders, share capital or its legal and regulatory compliance obligations or practices, some or all of which could have an adverse effect on our business.

We may also sell all or part of one or more of our businesses, including our subsidiaries, for a variety of reasons including changes in strategic focus, redeployment of capital, contractual obligations and regulatory requirements. See also “Business— Overview of Our Products and Services — Insurance”.

We and our customers are exposed to fluctuations in foreign exchange rates.

Several of our borrowers enter into derivative contracts to manage their foreign exchange risk exposures. Volatility in exchange rates may result in increased mark-to-market losses in derivative transactions for our clients. Upon the maturity or premature termination of the derivative contracts, these mark-to-market losses become receivables owed to us. Consequently, we become exposed to various kinds of risks including but not limited to credit risk, market risk and exchange risk.

As discussed above, in the past, concerns over India’s current account deficit and changes in capital flows due to changes in U.S. monetary policy have caused the rupee to depreciate against the dollar. See “—Risks relating to India and Other Economic and Market Risks—Current account deficits, including trade deficits, and capital flow and exchange rate volatility could adversely affect our business and the price of our equity shares and ADSs” . Some of our borrowers with foreign exchange and derivative exposures may be adversely impacted by the depreciation of the rupee. These include borrowers impacted by higher rupee denominated interest or principal repayment on unhedged foreign currency borrowings; increases in the cost of raw material imports where there is limited ability to pass through such escalations to customers; and the escalation of project costs due to higher imported equipment costs; and borrowers that may have taken adverse positions in the foreign exchange markets. The failure of our borrowers to manage their exposures to foreign exchange and derivative risk, particularly adverse movements and volatility in foreign exchange rates, may adversely affect our borrowers and consequently the quality of our exposure to our borrowers and our business volumes and profitability.

In January 2014, the Reserve Bank of India issued guidelines requiring higher capital and provisioning requirements for banks on their exposures to companies having unhedged foreign currency exposure, based on an assessment of likely loss on such exposures compared to the earnings of the corporate. An increase in non-performing or restructured assets on account of our borrowers’ inability to manage exchange rate risk and any increased capital or provisioning requirement against such exposures may have an adverse impact on our profitability, our business and the price of our equity shares and ADSs. We have adopted certain risk management policies to mitigate such risk. However, there is no assurance that such measures will be fully effective in mitigating such risks.

Entry into new businesses or rapid growth in existing loan portfolios may expose us to increased risks that may adversely affect our business.

The rapid growth of our retail loan business and our rural initiative exposes us to increased risks within India including higher levels of non-performing loans in our unsecured retail credit portfolio, increased

operational risk, increased fraud risk and increased regulatory and legal risk. Since fiscal 2012 we have focused on scaling up our retail lending volumes and since fiscal 2015, we have also seen an increase in our retail unsecured portfolio. Our net domestic retail loan portfolio grew by 18.5% in fiscal 2017 compared to an increase of 5.0% in our overall gross loan portfolio. Further, we are also focusing on scaling up our business and distribution network in rural areas. While we have taken measures to address the risks in these businesses, there can be no assurance that the businesses would perform according to our expectations or that there would not be any adverse developments in these businesses in the future. Our inability to manage such risks may have an adverse impact on our future business and strategy, our asset quality and profitability and the price of our equity shares and ADSs.

Our industry is very competitive and our strategy depends on our ability to compete effectively.

Within the Indian market, we face intense competition from other commercial banks, investment banks, insurance companies, non-bank finance companies, new private sector banks like payments banks and small finance banks and non-bank entities offering retail payments services. Some Indian public and private sector banks have experienced higher growth and increase in market shares relative to us. The Reserve Bank of India has issued licenses to two new private sector banks, and in-principle licenses to 10 small finance banks and 11 payments banks. Of these, six small finance banks and four payments banks have begun operations and three payments banks have surrendered, or announced their intention to surrender, their licences. The Reserve Bank of India has also issued guidelines with respect to a continuous licensing policy for universal banks in the private sector. The expansion of existing competitors or the entry of new competitors could increase competition. Further, technology innovations in mobility and digitization of financial services require banks to continuously develop new and simplified models for offering banking products and services. Innovations in the payments system and increasing use of mobile banking are leading to emergence of new platforms for cashless payments. This can also lead to new types of banks expanding their presence in other financial products like insurance and mutual funds. These trends in technology could increase competitive pressures on banks, including us, to adapt to new operating models and upgrade back-end infrastructure on an ongoing basis. There is no assurance that we will be able to continue to respond promptly to new technology developments, and be in a position to dedicate resources to upgrade our systems and compete with new players entering the market. In addition, the moderation of growth in the Indian banking sector may lead to greater competition for business opportunities.

We face competition from non-banking finance companies that are lending in segments in which banks also have a presence, including home loans and vehicle loans. Their presence in the market may grow during periods when banks are unable to grow their advances due to challenges and stress in other businesses. There is no assurance that we will be able to effectively compete with these non-banking finance companies at all times. Further, changes in the banking sector structure due to consolidation as well as entry of new competitors may lead to volatility and new challenges and may increase pressure on banks to remain competitive.

In October 2013, the Reserve Bank of India completely deregulated branch licensing requirements and banks are permitted to open branches across Tier 1 to Tier 6 centers without the prior approval of the Reserve Bank of India, subject to them maintaining a prescribed proportion of 25% of their incremental branches in rural and semi-urban areas. Banks are also allowed to merge, close or shift a branch in metropolitan and urban centers without prior approval. See also “ Supervision and Regulation—Regulations Relating to the Opening of Branches ”. In March 2017, the Reserve Bank of India issued revised guidelines on the rationalization of branch authorisation. As per the revised guidelines, banks are permitted to open, unless otherwise specifically restricted, banking outlets in Tier 1 to Tier 6 centers without having the need to take permission from the Reserve Bank of India in each case. The opening of banking outlets during a financial year will be subject to condition that at least 25% of the total number of banking outlets opened during a financial year should be opened in unbanked rural centers.

The Reserve Bank of India has also released the framework for the presence of foreign banks in India, and has proposed according treatment substantively similar to domestic banks for foreign banks, based on the principles of reciprocity and subsidiary mode of presence. In May 2014, the Reserve Bank of India released the report of the committee constituted to review the governance of boards of banks in India which, among others, has proposed several measures aimed at improving the governance, ownership and board oversight of public sector banks. Following these recommendations, the Government split the position of chairman and managing director in public sector banks such that one person is no longer permitted to hold both positions. Any changes in the banking structure in India, including the entry of new banks, greater competition between existing players and improvement in the efficiency and competitiveness of existing banks, may have an adverse impact on our business. Due to competitive pressures, we may be unable to successfully execute our growth strategy or offer

products and services at reasonable returns and this may adversely impact our business. See also “Business—Competition” and “Overview of the Indian Financial Sector—Commercial Banks—Foreign Banks ”.

In our international operations we also face intense competition from the full range of competitors in the financial services industry, both banks and non-banks and both Indian and foreign banks. We remain a small to mid-size player in the international markets and many of our competitors have resources much greater than our own.

Changes in the regulation and structure of the financial markets in India may adversely impact our business.

The Indian financial markets have in recent years experienced, and continue to experience, changes and developments aimed at reducing the cost and improving the quality of service delivery to users of financial services. We may experience an adverse impact on the cash float and fees from our cash management business resulting from the development and increased usage of payment systems, as well as other similar structural changes. Some structural changes in banking transactions in India include free access for a customer of any bank to ATMs of all other banks with restrictions on the amount and number of transactions. Furthermore, the Reserve Bank of India, from time to time, also imposes limits on transaction charges levied by banks on customers, including those on cash and card transactions. Banks were directed to remove foreclosure charges on home loans and floating rate term loans given to individual borrowers. Banks were prohibited from levying penalty on non-operative accounts for non-maintenance of minimum balance. Such developments may adversely impact the profitability of banks, including us, by reducing float balances and fee incomes, and increasing costs. See also “— The regulatory environment for financial institutions is facing unprecedented change in the post-financial crisis environment ”. Our subsidiaries are also subject to similar risks. For example, in the Union Budget for fiscal 2015, the Finance Minister announced an increase in the long-term capital gains tax rate on investments in debt mutual funds from 10% to 20% and also increased the minimum holding period for qualification as a long-term investment from 12 months to 36 months. Further, starting from April 2015, the Association of Mutual Funds of India has introduced a cap of 100 basis points on upfront commission for all mutual fund schemes. These changes may have an impact on the inflows and earnings of asset management companies, including our asset management subsidiary and also affect our fee and other incomes related to such activity. See also “— While our insurance businesses are an important part of our business, there can be no assurance of their future rates of growth or levels of profitability ”.

Additional capital requirements of our insurance subsidiaries or our inability to monetize a part of our shareholding in these subsidiaries may adversely impact our business and the price of our equity shares and ADSs.

Although, our insurance businesses are profitable and we currently do not anticipate they would require capital, additional capital may be required to support the business which may, among other reasons, arise due to regulatory requirements. For instance, in the past, in accordance with an order of the Insurance Regulatory and Development Authority of India, all general insurance companies in India, including our general insurance subsidiary, ICICI Lombard General Insurance Company Limited, were required to provide for losses on the third-party motor pool (a multilateral arrangement for insurance in respect of third-party claims against commercial vehicles, the results of which were shared by all general insurance companies in proportion to their overall market share). Since the losses were allocated to general insurance companies based on their overall market shares, the profitability and solvency ratio of our general insurance subsidiary were adversely impacted. Accordingly, we invested Rs. 740.0 million of capital into our general insurance subsidiary in fiscal 2013. Our ability to invest additional capital in these businesses is subject to the Reserve Bank of India’s regulations on capital adequacy and its para-banking guidelines that prescribe limits for our aggregate investment in financial sector enterprises. All such investments require prior approval of the Reserve Bank of India. See also “— Loss reserves for our general insurance business are based on estimates as to future claims liabilities and adverse developments relating to claims could lead to further reserve additions and materially adversely affect the operation of our general insurance subsidiary ”.

Any additional capital requirements of our insurance subsidiaries and restrictions on our ability to capitalize them could adversely impact their growth, our future capital adequacy, our financial performance and the price of our equity shares and ADSs.

The Insurance Laws (Amendment) Act, 2015, increased the foreign shareholding limit in insurance companies from 26.0% to 49.0%, subject to the companies being Indian-owned and controlled, and to regulatory approval. During fiscal 2016, we sold a 6.0% stake in our life insurance subsidiary, ICICI Prudential Life Insurance Company, to financial investors, thereby reducing our share ownership in ICICI Prudential Life Insurance Company from approximately 74% to 68%. In fiscal 2017, we sold a further 12.63% out of our

shareholding in ICICI Prudential Life Insurance Company through an offer for sale in an initial public offering of its shares. ICICI Prudential Life Insurance Company was listed on the National Stock Exchange of India Limited and the BSE Limited on September 29, 2016. During fiscal 2016, Fairfax Financial Holdings and ICICI Bank agreed that Fairfax Financial Holdings (through its affiliate) would increase its shareholding in ICICI Lombard General Insurance Company by 9.0%. The transaction was completed in March 2016, resulting in our share ownership in ICICI Lombard General Insurance Company reducing to 63%. In June 2017, our Board of Directors of the Bank approved the sale of a part of our shareholding in ICICI Lombard General Insurance Company Limited in an initial public offering by the Company, subject to requisite approvals and market conditions. There is no assurance that we will be able to complete the above sale as planned or that we will undertake further monetization of our investments in our subsidiaries, through public offering or otherwise, or of the level of valuation of the subsidiaries at which such monetization may take place. See also “ Business—Overview of Our Products and Services—Insurance” and “—While our insurance businesses are an important part of our business, there can be no assurance of their future rates of growth or levels of profitability ”.

While our insurance businesses are an important part of our business, there can be no assurance of their future rates of growth or levels of profitability.

Our life insurance and general insurance businesses are an important part of our business. See also “ Business—Overview of Our Products and Services—Insurance ”. These businesses have experienced volatility in growth rates in the past and there can be no assurance of their future rates of growth or profitability.

The Indian life insurance sector has experienced significant regulatory changes in recent years. In fiscal 2011, the Insurance Regulatory and Development Authority of India changed the regulations relating to unit-linked life insurance products. Subsequently, the Insurance Regulatory and Development Authority of India also issued revised regulations relating to non-linked life insurance products, which became effective during fiscal 2014. The key changes related to commissions payable to agents and distributors, lapse of policies, surrender values and minimum death benefits. As a result of these changes, the life insurance sector experienced low growth and changes in the product mix in recent years, as life insurance companies were required to modify their products and distribution strategies. While there was initially a shift in the product mix towards non-unit linked products, more recently the share of unit-linked products has increased driven by favorable cost structures of these products from a customer perspective, as well as by improved capital market conditions. Linked products contributed to 85.9% of the retail weighted received premium of ICICI Prudential Life Insurance Company in fiscal 2017, compared to 83.3% of the retail weighted received premium in fiscal 2016, 84.8% in fiscal 2015 and 66.5% in fiscal 2014. The demand for these products may be influenced by any volatility or downturn in capital markets. The regulatory changes have also resulted in reduced profit margins on life insurance products. In fiscal 2015, the Insurance Laws (Amendment) Act, 2015, amended the existing statute to provide that no policy of life insurance shall be called in question on any grounds, including misstatement of facts or fraud, at any time after three years from the date of the policy, i.e., from the date of issuance of the policy, commencement of risk, revival of the policy or the rider to the policy, whichever is later.

ICICI Lombard General Insurance Company’s gross direct premium income (GDPI) was Rs. 107.3 billion in fiscal 2017, a growth of 32.6% over fiscal 2016. ICICI Lombard General Insurance Company’s growth and profitability depend on various factors, including the proportion of certain profitable products in its portfolio, the maintenance on its relationship with key distribution partners and reinsurers, continuation of support by the government of India of certain insurance schemes, regulatory changes, and market movements. There can be no assurance of the future rates of growth in the insurance business. While this subsidiary has been making profits since fiscal 2013, there can be no assurance of the future profitability or rates of growth in the insurance business.

The Insurance Regulatory Development Authority of India has from time to time proposed changes to the regulations governing distribution of insurance products by corporate agents, including banks. ICICI Bank is a corporate agent of its insurance subsidiaries and accounts for a significant portion of the business volumes of its life insurance subsidiary. While the latest regulatory proposals are not expected to impact this activity significantly, any future regulatory restrictions may require our insurance subsidiaries to change their distribution strategies, which may result in increased costs and lower business volumes, as well as impacting ICICI Bank’s distribution of their products and the associated fee income. A slowdown in growth in the Indian economy, further regulatory changes or customer dissatisfaction with our insurance products could adversely impact the future growth of these businesses. See also “— The regulatory environment for financial institutions is facing unprecedented change in the post-financial crisis environment ”. Any slowdown in these businesses

and in particular in the life insurance business could have an adverse impact on our business and the price of our equity shares and ADSs.

The proposed initial public offerings of our general insurance subsidiary may not be completed, and if completed, will increase the complexity of our business.

Our Board of Directors has approved the further sale of up to approximately 7.0% out of our shareholding in ICICI Lombard General Insurance Company through an offer for sale in an initial public offering of the company’s shares, subject to necessary approvals and market conditions, and ICICI Lombard General Insurance Company has filed a draft red herring prospectus with the Securities and Exchange Board of India for the proposed public offering.

However, adverse developments in the financial markets, the Indian general insurance industry, or in the business of our general insurance subsidiary, in addition to various other factors, may result in our failure to complete the proposed initial public offering on the terms currently contemplated, or at all. Our inability to complete the initial public offering on the terms currently contemplated, or at all, may adversely affect our results of operation and financial condition.

If completed, the proposed initial public offering will lead to increased complexity in our business. Upon becoming a publicly traded company, our general insurance subsidiary will have to begin interacting with public company investors and complying with the increasingly complex laws pertaining to public companies. If our and our subsidiary’s management teams are not able to successfully or efficiently manage our subsidiary’s transition to being a public company, increased oversight and continuous scrutiny of securities analysts and investors, it could adversely affect our business, results of operations and financial condition.

Actuarial experience and other factors could differ from assumptions made in the calculation of life actuarial reserves and other actuarial information.

The assumptions our life insurance subsidiary makes in assessing its life insurance reserves and computing other actuarial information may differ from what it experiences in the future. These assumptions include the assessment of the long-term development of interest rates, investment returns, the allocation of investments between equity, fixed income and other categories, persistency, mortality and morbidity rates, policyholder lapses, policy discontinuation and future expense levels. In addition, there is risk that the model used to estimate life and health insurance reserves based on such assumptions is itself incorrect.

Our life insurance subsidiary monitors its actual experience of these assumptions and to the extent that it considers any deviation from assumption to continue in the longer term, it refines its long-term assumptions. Changes in any such assumptions may lead to changes in the estimates of life and health insurance reserves and other actuarial information. Such changes may also impact the valuation of our life insurance subsidiary by existing or potential investors, and the valuation at which any future monetization of our shareholding in the life insurance subsidiary takes place, if at all.

Loss reserves for our general insurance business are based on estimates as to future claims liabilities and adverse developments relating to claims could lead to further reserve additions and materially adversely affect the operation of our general insurance subsidiary.

In accordance with the general insurance industry practice and accounting and regulatory requirements, our general insurance subsidiary establishes reserves for loss and loss adjustment expenses related to its general insurance business. Reserves are based on estimates of future payments that will be made in respect of claims, including expenses relating to such claims. Such estimates are made on both a case-by-case basis of claims that have been reported but not settled, based on the facts and circumstances available at the time the reserves are established, as well as in respect of losses that have been incurred but not reported. These reserves represent the estimated ultimate cost necessary to bring all pending claims to final settlement.

Reserves are subject to change due to a number of variables which affect the ultimate cost of claims, such as changes in claims handling procedures, legal environment, social attitudes, results of litigation, costs of repairs, changing trends in medical costs, minimum wages and other factors such as inflation and exchange rates. Our general insurance subsidiary’s reserves for environmental and other latent claims are particularly subject to such variables. The results of operations of our general insurance subsidiary depend significantly upon the extent to which its actual claims experience is consistent with the assumptions it uses in setting the prices for products and establishing the liabilities for obligations for technical provisions and claims. To the

extent that its actual claims experience is less favorable than the underlying assumptions used in establishing such liabilities, it may be required to increase its reserves, which may materially adversely affect its results of operations.

Established loss reserves estimates are periodically adjusted in the ordinary course of settlement, using the most current information available to management, and any adjustments resulting from changes in reserve estimates are reflected in current results of operations. Our general insurance subsidiary also conducts reviews of various lines of business to consider the adequacy of reserve levels. Based on current information available and on the basis of internal procedures, the management of our general insurance subsidiary considers that these reserves are adequate. However, because the establishment of reserves for loss and loss adjustment expenses is an inherently uncertain process, there can be no assurance that ultimate losses will not materially exceed the established reserves for loss and loss adjustment expenses and have a material adverse effect on the results of operations of our general insurance subsidiary. See also “— Additional capital requirements of our insurance subsidiaries or our inability to monetize a part of our shareholding in these subsidiaries may adversely impact our business and the price of our equity shares and ADSs ”.

The financial results of our insurance subsidiaries could be materially adversely affected by the occurrence of catastrophe.

Portions of our general insurance subsidiary’s business may cover losses from unpredictable events such as hurricanes, windstorms, monsoons, earthquakes, fires, industrial explosions, floods, riots and other man-made or natural disasters, including acts of terrorism. The incidence and severity of these catastrophes in any given period are inherently unpredictable.

In addition, our life insurance subsidiary’s operations are also exposed to claims arising out of catastrophes due to increased mortality and morbidity claims of affected customers. In addition, catastrophes could result in losses in the investment portfolios of our life insurance subsidiary due to, among other reasons, the failure of its counterparties to perform their obligations or significant volatility or disruption in the financial markets.

Although our subsidiaries monitor their overall exposure to catastrophes and other unpredictable events in each geographic region and determine their underwriting limits related to insurance coverage for losses from catastrophic events, the subsidiaries generally seek to reduce their exposure through the purchase of reinsurance, selective underwriting practices and by monitoring risk accumulation. Claims relating to catastrophes may result in unusually high levels of losses and may require additional capital to maintain solvency margins and could have a material adverse effect on our financial position or results of operations.

There is operational risk associated with the financial industry which, when realized, may have an adverse impact on our business.

We, like all financial institutions, are exposed to many types of operational risk, including the risk of fraud or other misconduct by employees or outsiders, unauthorized transactions by employees and third parties (including violation of regulations for prevention of corrupt practices, and other regulations governing our business activities), misreporting or non-reporting with respect to statutory, legal or regulatory reporting and disclosure obligations, or operational errors, including non-compliance with internal processes, clerical or recordkeeping and reconciliation errors or errors resulting from faulty computer or telecommunications systems. We have experienced significant growth in a fast changing environment, and management as well as our regulators, are aware that this may pose significant challenges to our control framework. As a result of our internal evaluations, we and our regulators have noted certain areas where our processes and controls could be improved. Our growth, particularly in retail lending, our rural initiative, our international business and our insurance businesses, exposes us to additional operational and control risks. Regulatory scrutiny of areas related to operational risk, including internal audit information, systems and data processing is increasing. The large size of our treasury and retail operations, which use automated control and recording systems as well as manual checks and recordkeeping, exposes us to the risk of errors in control, recordkeeping and reconciliation. The increasing size of our insurance business and the complexities of the products expose us to the risk that the models set up on actuarial software to compute the actuarial liabilities and deferred acquisition cost may contain errors or may require continuous improvement over a period of time. We also outsource some functions, like collections, to other agencies. Given our high volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully rectified. In addition, our dependence upon automated systems to record and process transactions may further increase the risk that technical system flaws, employee tampering, manipulation of those systems and deficiency in access control management will result in losses that are difficult to detect. We may also be subject to disruptions of our operating systems, arising from events that are wholly or partially beyond our control (including, for example, computer viruses or electrical or telecommunication outages), which may give rise to deterioration in customer service

and to loss or liability to us. Unexpected events, such as the withdrawal of high denomination currency notes, could result in a sharp increase in our transaction volumes and increase the pressure on our systems to keep pace with regulatory changes in a short period of time, which may result in inadvertent operational errors in our branch operations and resultant regulatory action. We are further exposed to the risk that external vendors may be unable to fulfil their contractual obligations to us (or will be subject to the same risk of fraud or operational errors by their respective employees as we are), and to the risk that our (or our vendors’) business continuity and data security systems prove not to be sufficiently adequate. We also face the risk that the design of our controls and procedures prove inadequate, or are circumvented, thereby causing delays in detection or errors in information. Although we maintain a system of controls designed to keep operational risk at appropriate levels, like all banks and insurance companies we have suffered losses from operational risk and there can be no assurance that we will not suffer losses from operational risks in the future that may be material in amount, and our reputation could be adversely affected by the occurrence of any such events involving our employees, customers or third parties. In addition, regulators or legal authorities may also hold banks, including us, liable for losses on account of customer errors such as inadvertent sharing of confidential account related information. There are inherent limitations to the effectiveness of any system especially of controls and procedures, including the possibility of human error, circumvention or over-riding of the controls and procedures, in a fast changing environment or when entering new areas of business or expanding geographic reach. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. We are committed to continuing to implement and improve internal controls and our risk management processes, and this remains a key priority for us. If, however, we are unable to manage operational risk in India and in the other jurisdictions in which we operate, or if we are perceived as being unable to manage such risk, we may be subject to enhanced regulatory oversight and scrutiny. For a discussion of how operational risk is managed, see also “Business—Risk Management—Operational Risk ”.

Fraud and significant security breaches in our computer system and network infrastructure could adversely impact our business.

Our business operations are based on a high volume of transactions. Although we take adequate measures to safeguard against system-related and other fraud, there can be no assurance that we would be able to prevent fraud. Our reputation could be adversely affected by fraud committed by employees, customers or outsiders, or by our perceived inability to properly manage fraud-related risks. Our inability or perceived inability to manage these risks could lead to enhanced regulatory oversight and scrutiny. Our branch network expansion, our rural initiative, our international growth and our expansion to product lines such as insurance may create additional challenges with respect to managing the risk of fraud due to increased geographical dispersion and use of intermediaries. See also “ Operating and Financial Review and Prospects—Provisions for Non-performing Assets and Restructured Loans ” and “Business—Risk Management—Operational Risk ”. Physical or electronic break-ins, security breaches or other disruptions caused by power disruptions or the increased use of technology could also affect the security of information stored in and transmitted through our computer systems and network infrastructure. Technology has been undergoing a rapid evolution driven by mobility, cloud computing and social networks and this has led to increased cyber threats such as distributed denial of service attacks, spear phishing attacks and proliferation of malware and trojans. Given our focus on technology and presence in diverse geographies, we are exposed to such attacks which may impact the confidentiality, integrity or availability of data pertaining to us or our customers, which in turn may cause damage to our reputation and adversely impact our business and financial results. While we maintain insurance coverage that may, in accordance with the policy terms and conditions, cover certain aspects of cyber risks, such insurance coverage may be insufficient to cover all losses. We have a governance framework in place for security and has implemented information security policies, procedures and technologies. However, considering that technology is currently in a phase of rapid evolution and considering that the methods used for cyber-attacks are also changing frequently or, in some cases, are not recognized until an actual attack, we may not be able to anticipate or to implement effective preventive measures against all security breaches. Like many other large global financial institutions, we have also experienced a distributed denial of services attack which was intended to disrupt customer access to our main portal. While our monitoring and mitigating controls were able to detect and effectively respond to this incident, there can be no assurance that these security measures will be successful in the future. A significant failure in security measures could have a material adverse effect on our business, our future financial performance, our stockholders’ equity and the price of our equity shares and ADSs.

System failures could adversely impact our business.

Given the large share of retail products and services and transaction banking services in our total business, the importance of systems technology to our business has increased significantly. We have also launched delivery of banking services through mobile phones, apart from ATMs, call centers and the Internet. While we have procedures to monitor for and prevent system failures, and to recover from system failures in the event they occur, there is no guarantee that these procedures will successfully prevent a system failure or allow us to recover quickly from a system failure. In the event that our data center is severely impacted due to a major

power outage, floods, earthquakes, internet link failures or other events, while we have a secondary disaster recovery data center, recovery of some of our systems and services may be delayed, thereby adversely impacting our operations and customer service levels. Any failure in our systems, particularly for retail products and services and transaction banking, could significantly affect our operations and the quality of our customer service and could result in enhanced regulatory scrutiny and business and financial losses that would adversely affect the price of our equity shares and ADSs. Regulatory scrutiny in this area is increasing. See also “— The enhanced supervisory and compliance environment in the financial sector increases the risk of regulatory action, whether formal or informal. Following the financial crisis, regulators are increasingly viewing us, as well as other financial institutions, as presenting a higher risk profile than in the past ”.

A determination against us in respect of disputed tax assessments may adversely impact our financial performance.

We are regularly assessed by the government of India’s tax authorities, and on account of outstanding tax demands we have included in contingent liabilities Rs. 51.0 billion in additional taxes in excess of our provisions at year-end fiscal 2017. These additional tax demands mainly relate to issues disputed by us and the tax authorities, such as the disallowance of depreciation on leased assets, disallowance of expenditure incurred towards exempt income, withdrawal of a special reserve, marked-to-market losses and indirect tax matters. As explained under “ Business—Legal and Regulatory Proceedings ”, no provision has been made in the accounts for these contingent liabilities. The Rs. 51.0 billion included in our contingent liabilities does not include further disputed tax assessments amounting to Rs. 53.1 billion mainly relating to bad debts written off and penalties levied, where the possibility of liability arising has been considered remote based on favorable Supreme Court decisions in other similar cases, and Rs. 2.3 billion relating to disallowance of taxes paid. See also “ Business—Legal and Regulatory Proceedings ”.

We have appealed all of these demands. While we expect that no additional liability will arise out of these disputed demands based on our consultations with tax counsel and favorable decisions in our own and other cases, there can be no assurance that these matters will be settled in our favor or that no further liability will arise out of these demands. Any additional tax liability may adversely impact our financial performance and the price of our equity shares and ADSs.

We are involved in various litigations. Any final judgment awarding material damages against us could have a material adverse impact on our future financial performance and our stockholders’ equity.

We and our group companies, or our or their directors or officers, are often involved in litigations (civil and criminal) in India and in the other jurisdictions in which we operate for a variety of reasons, which generally arise because we seek to recover our dues from borrowers or because customers seek claims against us. The majority of these cases arise in the normal course of business and we believe, based on the facts of the cases and consultation with counsel, that these cases generally do not involve the risk of a material adverse impact on our financial performance or stockholders’ equity. We estimate the probability of losses that may be incurred in connection with legal and regulatory proceedings as of the date on which our unconsolidated and consolidated financial statements are prepared. We recognize a provision when we have a present obligation as a result of a past event, it is probable that an outflow of resources will be required to settle the obligation and a reliable estimate of the amount of the obligation can be made. We determine the amount of provision based on our estimate of the amount required to settle the obligation at the balance sheet date, supplemented by our experience in similar situations. We review provisions at each balance sheet date and adjust them to reflect current estimates. In cases where the available information indicates that a loss is reasonably possible but the amount of such loss cannot be reasonably estimated, we make a disclosure to this effect in the unconsolidated and consolidated financial statements. In certain instances, present and former employees have instituted legal and other proceedings against us alleging irregularities. When there is only a remote risk of loss, we do not recognize a provision nor do we include a disclosure in the unconsolidated and consolidated financial statements. See also “ Business—Legal and Regulatory Proceedings ”. We cannot guarantee that the judgments in any of the litigation in which we are involved would be favorable to us and if our assessment of the risk changes, our view on provisions will also change.

Any inability to attract and retain talented professionals may adversely impact our business.

Our business has become more complex with both product line expansion including the insurance area and geographic expansion internationally and through the rural initiatives. Our continued success depends in part on the continued service of key members of our management team and our ability to continue to attract, train,

motivate and retain highly qualified professionals. This is a key element of our strategy and we believe it to be a significant source of competitive advantage. The successful implementation of our strategy depends on the availability of skilled management, both at our head office and at each of our business units and international locations and on our ability to attract and train young professionals. A substantial portion of our compensation structure for middle and senior management is in the form of employee stock options, and dependent on the market price of our equity shares. Depending on market and business conditions, we may decide to reduce our employee strength in certain of our businesses. Increased competition, including the entry of new banks into an already competitive sector, may affect our ability to hire and retain qualified employees. Further, any stringent requirements by our regulator for appointing key members in the management may require us to reorganize our management structure and may affect our ability to identify suitable professionals for various roles. If we or one of our business units or other functions fail to staff operations appropriately, or lose one or more key senior executives or qualified young professionals and fail to replace them in a satisfactory and timely manner, our business, financial condition and results of operations, including our control and operational risks, may be adversely affected. Likewise, if we fail to attract and appropriately train, motivate and retain young professionals or other talent, our business may likewise be affected. See also “ Business—Employees ”.

Adoption of a different basis of accounting or new accounting standards may result in changes in our reported financial position and results of operations for future and prior periods.

The financial statements and other financial information included or incorporated by reference in this annual report are based on our unconsolidated and consolidated financial statements under Indian GAAP. The Institute of Chartered Accountants of India has issued Ind AS (a revised set of accounting standards) which largely converges the Indian accounting standards with International Financial Reporting Standards. The Ministry of Corporate Affairs, which is the law making authority for adoption of accounting standards in India, has notified these Ind AS for adoption. Further, the ministry has also issued a roadmap for transition to Ind AS by Indian companies in a phased manner starting from April 1, 2016. For banking companies and non-banking finance companies, the implementation of Ind AS will begin from April 1, 2018 and for insurance companies it will begin from April 1, 2020. Accordingly, ICICI Bank and our group companies, would report its financials as per Ind AS from April 1, 2018 onwards. Financial statements prepared under standards different from existing GAAP may diverge significantly from the financial statements and other financial information included or incorporated by reference in this annual report. The major areas of differences include classification and mark-to-market accounting of financial assets, impairment of financial assets, accounting of loan processing fees and costs, amortization of premium/discount on purchase of financial assets, employee stock option, deferred tax and consolidation accounting.

Ind AS 109 - Financial Instruments (Standard equivalent to International Financial Reporting Standard 9) would have a significant impact on the way financial assets and liabilities are classified and measured, resulting in volatility in profit or loss and equity. See also “Operating and Financial review Prospects – Convergence of Indian accounting standards with International Financial Reporting Standards”

Risks Relating to ADSs and Equity Shares

You will not be able to vote your ADSs and your ability to withdraw equity shares from the depositary facility is subject to delays and legal restrictions.

Our ADS holders have no voting rights unlike holders of our equity shares who have voting rights. For certain information regarding the voting rights of the equity shares underlying our ADSs, see also “ Business—Shareholding Structure and Relationship with the Government of India ”. If you wish, you may withdraw the equity shares underlying your ADSs and seek to exercise your voting rights under the equity shares you obtain from the withdrawal. However, for foreign investors, this withdrawal process may be subject to delays. For a discussion of the legal restrictions triggered by a withdrawal of the equity shares from the depositary facility upon surrender of ADSs, see also “ Restriction on Foreign Ownership of Indian Securities ”.

Your holdings may be diluted by additional issuances of equity and any dilution may adversely affect the market price of our equity shares and ADSs.

In fiscal 2008, we concluded a capital raising exercise comprising a public offering in India and an ADS offering aggregating Rs. 199.7 billion. We may conduct additional equity offerings to fund the growth of our business, including our international operations, our insurance business or our other subsidiaries. In addition, up to 10.0% of our issued equity shares from time to time, may be granted in accordance with our Employee Stock Option Scheme. Any future issuance of equity shares or ADSs or exercise of employee stock options would dilute the positions of investors in equity shares and ADSs and could adversely affect the market price of our equity shares and ADSs.

You may be unable to exercise preemptive rights available to other shareholders.

A company incorporated in India must offer its holders of equity shares preemptive rights to subscribe and pay for a proportionate number of shares to maintain their existing ownership percentages prior to the issuance of any new equity shares, unless these rights have been waived by at least 75.0% of the company’s shareholders present and voting at a shareholders’ general meeting. United States investors in ADSs may be unable to exercise these preemptive rights for equity shares underlying ADSs unless a registration statement under the Securities Act of 1933, as amended (the “ Securities Act ”) is effective with respect to such rights or an exemption from the registration requirements of the Securities Act is available. Our decision to file a registration statement will depend on the costs and potential liabilities associated with any such registration as well as the perceived benefits of enabling investors in ADSs to exercise their preemptive rights and any other factors we consider appropriate at such time. To the extent that investors in ADSs are unable to exercise preemptive rights, their proportional ownership interests in us would be reduced.

Your ability to sell in India any equity shares withdrawn from the depositary facility, the conversion of rupee proceeds from such sale into a foreign currency and the repatriation of such foreign currency may be subject to delays if specific approval of the Reserve Bank of India is required.

ADS holders seeking to sell in India any equity shares withdrawn upon surrender of ADSs, convert the rupee proceeds from such sale into a foreign currency or repatriate such foreign currency may need the Reserve Bank of India’s approval for each such transaction. See also “ Restriction on Foreign Ownership of Indian Securities ”. We cannot guarantee that any such approval will be obtained in a timely manner or at terms favorable to the investor. Because of possible delays in obtaining the requisite approvals, investors in equity shares may be prevented from realizing gains during periods of price increases or limiting losses during periods of price declines.

Restrictions on deposit of equity shares in the depositary facility could adversely affect the price of our ADSs.

Under current Indian regulations, an ADS holder who surrenders ADSs and withdraws equity shares may deposit those equity shares again in the depositary facility in exchange for ADSs. An investor who has purchased equity shares in the Indian market may also deposit those equity shares in the ADS program. However, the deposit of equity shares may be subject to securities law restrictions and the restriction that the cumulative aggregate number of equity shares that can be deposited as of any time cannot exceed the cumulative aggregate number represented by ADSs converted into underlying equity shares as of such time. These restrictions increase the risk that the market price of our ADSs will be below that of the equity shares.

Certain shareholders own a large percentage of our equity shares and their actions could adversely affect the price of our equity shares and ADSs.

The Life Insurance Corporation of India, the General Insurance Corporation of India and other government-owned general insurance companies, all of which are directly controlled by the Indian government, are among our principal shareholders. At June 30, 2017, the Life Insurance Corporation of India held 10.4% and the General Insurance Corporation of India and other government-owned general insurance companies held 1.7%   of our outstanding equity shares. See also “ Business—Shareholding Structure and Relationship with the Government of India ”. Any substantial sale of our equity shares by these or other large shareholders could adversely affect the price of our equity shares and ADSs. The Reserve Bank of India, in exercise of powers conferred by the Banking Regulation Act has notified a ceiling on voting rights in a banking company for single shareholder of 15.0%. Deutsche Bank Trust Company Americas held approximately 25.1% of our equity shares at June 30, 2017 as depositary for ADS holders and currently votes on only 15.0% of these shares as per the ceiling notified by the Reserve Bank of India. In addition, under the terms of our deposit agreement, Deutsche Bank Trust Company Americas must vote these shares as directed by our Board of Directors. See also “ Overview of the Indian Financial Sector—Structural Reforms—Amendments to the Banking Regulation Act ”.

Conditions in the Indian securities market may adversely affect the price or liquidity of our equity shares and ADSs.

The Indian securities markets are smaller and more volatile than securities markets in developed economies. In the past, the Indian stock exchanges have experienced high volatility and other problems that have affected the market price and liquidity of the listed securities, including temporary exchange closures, broker defaults, settlement delays and strikes by brokers. In April 2003, the decline in the price of the equity shares of a leading Indian software company created volatility in the Indian stock markets and created temporary concerns regarding our exposure to the equity markets. On May 17, 2004, the S&P BSE Sensex fell by 565 points from

5,070 to 4,505, creating temporary concerns regarding our exposure to the equity markets. Both the BSE Limited and the National Stock Exchange of India Limited halted trading on the exchanges on May 17, 2004 in view of the sharp fall in prices of securities. The Indian securities markets experienced rapid appreciation during fiscal 2006 but underwent a sharp correction in May 2006. The markets experienced a recovery thereafter and the S&P BSE Sensex reached an all-time high of 20,873 on January 8, 2008 but subsequently experienced a sharp correction, with the S&P BSE Sensex declining to 8,160 on March 9, 2009. In the 24 months since then, the equity markets had recovered with the S&P BSE Sensex at 19,445 at year-end fiscal 2011. However, the European debt crisis, volatile crude oil prices and concerns on growth in India caused a decline in the domestic equity markets with the S&P BSE Sensex at 17,404 at March 30, 2012. The markets have recovered subsequently and at year-end fiscal 2017 the S&P BSE Sensex was at 29,621. In recent years, there have been changes in laws and regulations regulating the taxation of dividend income, which have impacted the Indian equity capital markets. See also “ Dividends ”. Similar problems or changes in the future could adversely affect the market price and liquidity of our equity shares and ADSs.

We are subject to regulatory restrictions on the payment of dividend to shareholders. Any change in such restrictions or increase in capital requirements may have an impact on our dividend payout to our equity share and ADS holders.

The Reserve Bank of India has prescribed limits on the dividend payout ratio of banks in India linked to certain parameters such as the risk-based capital ratio and net non-performing assets ratio. Under the Reserve Bank of India’s Basel III guidelines, banks are subject to higher minimum capital requirements and must maintain a capital conservation buffer above the minimum requirements to avoid restrictions on capital distributions and discretionary bonus payments. Any change in restrictions on payment of dividend or capital requirements may limit our ability to pay dividends to our equity share and ADS holders.

Settlement of trades of equity shares on Indian stock exchanges may be subject to delays.

The equity shares represented by ADSs are currently listed on the BSE Limited and the National Stock Exchange of India Limited. Settlement on those stock exchanges may be subject to delays and an investor in equity shares withdrawn from the depositary facility upon surrender of ADSs may not be able to settle trades on such stock exchanges in a timely manner. See also “ —Conditions in the Indian securities market may adversely affect the price or liquidity of our equity shares and ADSs ”.

Changes in Indian regulations on foreign ownership, a change in investor preferences or an increase in the number of ADSs outstanding could adversely affect the price of our equity shares and ADSs.

ADSs issued by companies in certain emerging markets, including India, may trade at a discount or a premium to the underlying equity shares, in part because of the restrictions on foreign ownership of the underlying equity shares. See also “ Restriction on Foreign Ownership of Indian Securities ”. Historically, our ADSs have generally traded at a small premium to the trading price of our underlying equity shares on the Indian stock exchanges. See also “ Market Price Information ”. We believe that this price premium resulted from the limited portion of our market capitalization represented by ADSs, restrictions imposed by Indian law on the conversion of equity shares into ADSs and an apparent preference among some investors to trade dollar-denominated securities. In fiscal 2006 and fiscal 2008, we conducted offerings of ADSs which increased the number of outstanding ADSs and we may conduct similar offerings in the future. Also, over time, some of the restrictions on the issuance of ADSs imposed by Indian law have been relaxed. As a result, any premium enjoyed by ADSs as compared to the equity shares may be reduced or eliminated as a result of offerings made or sponsored by us, changes in Indian law permitting further conversion of equity shares into ADSs or a change in investor preferences.

Because the equity shares underlying ADSs are quoted in rupees in India, you may be subject to potential losses arising out of exchange rate risk on the Indian rupee.

Investors who purchase ADSs are required to pay for ADSs in U.S. dollars and are subject to currency fluctuation risk and convertibility risks since the equity shares underlying ADSs are quoted in rupees on the Indian stock exchanges on which they are listed. Dividends on the equity shares will also be paid in rupees and then converted into U.S. dollars for distribution to ADS investors. Investors who seek to convert the rupee proceeds of a sale of equity shares withdrawn upon surrender of ADSs into foreign currency and repatriate the foreign currency may need to obtain the approval of the Reserve Bank of India for each such transaction. See also “ —Your ability to sell in India any equity shares withdrawn from the depositary facility, the conversion of rupee proceeds from such sale into a foreign currency and the repatriation of such foreign currency may be subject to delays if specific approval of the Reserve Bank of India is required ” and “ Exchange Rates ”.

You may be subject to Indian taxes arising out of capital gains.

In certain circumstances, capital gains arising on the sale of the underlying equity shares are subject to Indian capital gains tax. Investors are advised to consult their own tax advisors and to carefully consider the potential tax consequences of owning ADSs or underlying equity shares. See also “ Taxation—Indian Tax ”.

There may be less company information available in Indian securities markets than in securities markets in the United States.

There is a difference between India and the United States in the level of regulation and monitoring of the securities markets and the activities of investors, brokers and other market participants. The Securities and Exchange Board of India is responsible for improving disclosure and regulating insider trading and other matters for the Indian securities markets. There may, however, be less publicly available information about Indian companies than is regularly made available by public companies in the United States.

Business

Overview

We are a diversified financial services group offering a wide range of banking and financial services to corporate and retail customers through a variety of delivery channels. We are the largest private sector bank in India in terms of total assets on a consolidated basis. Apart from banking products and services, we offer life and general insurance, asset management, securities brokering and private equity products and services through our specialized subsidiaries. Our total assets at year-end fiscal 2017 were Rs. 9,860.4 billion. Our consolidated capital and reserves at year-end fiscal 2017 were Rs. 1,046.3 billion and our consolidated net profit for fiscal 2017 was Rs. 101.9 billion.

Our primary business consists of commercial banking operations for Indian corporate and retail customers. We provide a range of commercial banking and project finance products and services, including loan products, fee and commission-based products and services, deposit products and foreign exchange and derivatives products to India’s leading corporations, middle market companies and small and medium enterprises. Our commercial banking operations for retail customers consist of retail lending and deposit taking and distribution of third party insurance and investment products. We also offer agricultural and rural banking products. We deliver our products and services through a variety of channels, including bank branches, ATMs, call centers, the internet, social media and mobile phones.

History

ICICI was formed in 1955 at the initiative of the World Bank, the government of India and Indian industry representatives. The principal objective was to create a development financial institution for providing medium-term and long-term project financing to Indian businesses. Until the late 1980s, ICICI primarily focused its activities on project finance, providing long-term funds to a variety of industrial projects. With the liberalization of the financial sector in India in the 1990s, ICICI transformed its business from a development financial institution offering only project finance to a diversified financial services provider that, along with its subsidiaries and other group companies, offered a wide variety of products and services. As India’s economy became more market-oriented and integrated with the world economy, ICICI capitalized on the new opportunities to provide a wider range of financial products and services to a broader spectrum of clients. ICICI Bank was incorporated in 1994 as a part of the ICICI group.

The issue of universal banking, which in the Indian context means conversion of long-term lending institutions such as ICICI into commercial banks, had been discussed at length in the late 1990s. Conversion into a bank offered ICICI the ability to accept low-cost demand deposits and offer a wider range of products and services, and greater opportunities for earning non-fund based income in the form of banking fees and commissions. ICICI Bank also considered various strategic alternatives in the context of the emerging competitive scenario in the Indian banking industry. ICICI Bank identified a large capital base and size and scale of operations as key success factors in the Indian banking industry. In view of the benefits of transformation into a bank and the Reserve Bank of India’s pronouncements on universal banking, ICICI and ICICI Bank merged in 2002.

The holding of government-controlled shareholders was 13.3% at June 30, 2017 against 13.1% at June 30, 2016 and 11.2% at June 30, 2015. The holding of Life Insurance Corporation of India was 10.4% at June 30, 2017 against 10.4% at June 30, 2016 and 8.5% at June 30, 2015.

We operate as an autonomous commercial enterprise and the Indian government has never directly held any of our shares. We are not aware of or a party to any shareholders’ agreement or voting trust relating to the ownership of the shares held by the government-controlled shareholders. We do not have any agreement with our government-controlled shareholders regarding management control, voting rights, anti-dilution or any other matter. Our Articles of Association provide for the government of India to appoint, pursuant to the provisions of guarantee agreements between the government of India and ICICI, a representative to our Board. The government of India has appointed one representative to our Board. We have traditionally invited a representative of each of the government-controlled insurance companies that are among our principal institutional shareholders, Life Insurance Corporation of India and General Insurance Corporation of India to join our Board. There is currently a representative of Life Insurance Corporation of India but no representative of General Insurance Corporation of India on our Board. See also “Management—Directors and Executive Officers ” for a discussion of the composition of our Board of Directors.

The holding of other Indian investors was 26.3% at June 30, 2017 against 21.8% at June 30, 2016 and 19.2% at June 30, 2015. The total holding of Indian investors was 39.6% at June 30, 2017 against 34.9% at June 30, 2016 and 30.4% at June 30, 2015. The holding of foreign investors was 60.4% at June 30, 2017 against 65.1% at June 30, 2016 and 69.6% at June 30, 2015. See also “ Supervision and Regulation—Reserve Bank of India Regulations—Ownership Restrictions ”. Deutsche Bank Trust Company Americas holds the equity shares represented by 805 million American Depositary Receipts outstanding as depositary on behalf of the holders of the American Depositary Shares. The American Depositary Shares are listed on the New York Stock Exchange. The Reserve Bank of India, exercising its powers under the Banking Regulation Act has notified a ceiling of 15.0% on the voting rights of a single shareholder in a banking company. Therefore, Deutsche Bank Trust Company Americas (as depositary), which held approximately 25.1% of our equity shares at June 30, 2017 can only vote 15.0% of our equity shares. In addition, under the terms of our deposit agreement, Deutsche Bank Trust Company Americas must vote these shares as directed by our Board of Directors. Our ADS holders themselves have no voting rights unlike holders of our equity shares who have voting rights. Except as stated above, no shareholder has differential voting rights.

Strategy

In fiscal 2017, we continued to focus on opportunities for sustainable profitable growth by enhancing our retail franchise, including growing our retail loan portfolio and maintaining the proportion of current and savings accounts and retail term deposits in our domestic deposit base. We continued to build our rural and inclusive banking franchise, focused on strengthening our insurance, asset management and securities businesses, and unlocking value from our investments in our insurance subsidiaries. We continued to leverage technology to improve the customer experience as well as our operating efficiency. During the withdrawal of high denomination currency notes and the introduction of new currency notes by the government of India in the second half of fiscal 2017, we ensured minimal disruptions in our banking operations, took steps to manage availability of cash, recalibration of our ATMs to accept new notes, announced waivers on specific banking transactions and enhanced our services to customers. During fiscal 2017, we continued to adopt a cautious approach to lending to the corporate sector, and refined and strengthened the framework for managing concentration risks, including thresholds and limits with respect to single borrower and group exposure. We focused on asset resolution and exposure reduction in identified areas though the progress was slower than expected. We maintained a strong capital position with capital adequacy ratios significantly above the regulatory requirements.

The success of our strategy depends on several factors, including our ability to grow our low cost deposit base, grow our loan book profitably, contain non-performing and restructured loans, resolve stressed assets promptly, manage our treasury business, maintain regulatory compliance in an evolving regulatory environment, address regulators’ assessments of and observations on our operations, and compete effectively in the Indian corporate and retail financial services market. Regulations governing the financial sector in India, including banking, insurance and asset management, continue to evolve, with a potential impact on the growth and profitability of financial services groups such as us. Our overseas branches are primarily funded from wholesale sources and global financial market conditions may impact our ability to raise funds and grow the business of our overseas branches.

Going forward, our objective will be to sustain our robust funding profile and leverage our capital base for profitable growth with diversification of risk. Our strategic priorities are summarized below:

Improving portfolio quality

Continuing to enhance our franchise

Meeting customer expectations on service quality and attracting and retaining talented professionals will be important elements of our strategy.

Overview of Our Products and Services

We offer products and services in the commercial banking area to corporate and retail customers, both domestic and international. We also undertake treasury operations and offer treasury-related products and services to our customers. We are also engaged in insurance, asset management, securities business, venture capital and private equity fund management through specialized subsidiaries.

Commercial Banking for Retail Customers

Our commercial banking operations for retail customers consist of retail lending and deposits, credit, debit and prepaid cards, depositary share accounts, distribution of third party investment and insurance products, other fee-based products and services, and the issuance of unsecured redeemable bonds.

Retail Lending Activities

Our retail lending activities include home loans, automobile loans, commercial business loans (including primarily commercial vehicle loans), business banking loans (including dealer funding and small ticket loans to small businesses), personal loans, credit cards, loans against time deposits, loans against securities, loans against jewelry and retail lending in rural markets. We also fund dealers who sell automobiles and commercial vehicles. The retail portfolio increased from Rs. 2,385.7 billion constituting 46.8% of gross loans at year-end fiscal 2016 to Rs. 2,689.6 billion constituting 50.2% of gross loans at year-end fiscal 2017. This was driven primarily by growth in secured retail lending categories like mortgages and automobile loans. We also selectively offer unsecured products such as personal loans and credit cards to our customers. We believe that retail credit has a robust long-term growth potential due to India’s favorable demographics and under-penetration of retail products in the Indian market.

Our retail asset products are generally fixed rate products repayable in equated monthly installments other than our floating rate home loan portfolio, where any change in the benchmark rate to which the rate of interest on the loan is referenced is passed on to the borrower on the first day of the succeeding quarter or succeeding month, as applicable. Any decrease in the rate of interest payable on floating rate home loans is generally implemented by an acceleration of the repayment schedule, keeping the monthly installment amount unchanged. Any increase in the rate of interest payable on floating rate home loans is generally effected in the first instance by an extension of the repayment schedule, keeping the monthly installment amount unchanged, and based on certain criteria, by changing the monthly installment amount. See also “ Risk Factors—Risks Relating to Our Business—Our banking and trading activities are particularly vulnerable to interest rate risk and volatility in interest rates could adversely affect our net interest margin, the value of our fixed income portfolio, our income from treasury operations, the quality of our loan portfolio and our financial performance ”.

Commercial Banking for Rural and Agricultural Customers

Our rural banking operation caters to the financial requirements of customers in rural and semi-urban locations, primarily engaged in agriculture and allied activities. We offer a comprehensive product suite covering the entire agricultural value chain including farmers, commodity traders, seed and farm input dealers and processors. Our products include working capital loans for growing crops and financing post harvest activities, including farm equipment loans and financing against warehouse receipts and gold jewelry. We also provide consumption loans for low-income customers. The Reserve Bank of India’s directed lending norms also require us to lend a portion of advances to the agricultural sector and micro enterprises. See also “—Loan Portfolio—Directed Lending” .

We offer financial solutions to micro-finance institutions, self-help groups, co-operatives constituted by farmers, corporations and medium enterprises engaged in agriculture-linked businesses. Rural banking services are offered through multiple channels including branches, micro ATMs, point of sale terminals and mobile branches. We have tied up with telecom companies to offer mobile based banking services. Our rural customers can also avail themselves of basic banking facilities at retail outlets like grocery shops and customer service points through business correspondents. As per the requirement of the Reserve Bank of India, we have formulated a board-approved financial inclusion plan to provide financial services to customers residing in rural and unbanked areas. From fiscal 2015, we have supported the government’s financial inclusion initiative to provide a bank account to every household in unbanked areas of the country. We have enabled remittances and account based transfers, based on Aadhaar, India’s unique identification number, for our customers who are beneficiaries of direct benefit transfers under the social security schemes of the government of India. During

fiscal 2016, we began offering insurance and pension products to our customers. The Bank has also tied up with National Commodity and Derivatives Exchange Limited to offer loans against electronic warehouse receipts. In fiscal 2017, the Bank launched a unique mobile application, Mera iMobile, which allows users, including non-ICICI Bank customers, in rural areas to access banking services as well as information on agricultural services. This application provides around 135 services and is available in English and several Indian regional languages. Rural banking presents significant challenges in terms of geographical coverage and high unit transaction costs. We continuously explore various models for operating through cost effective structures in rural locations, including technology-based channels and have opened 571 low cost branches in rural locations, which offer basic banking services to rural customers. We have also pursued initiatives in empowering villages and in creating a digital ecosystem in line with the government’s focus to shift towards a less-cash economy. The village promotion programme encompasses digitization of transactions and commercial activities and provides credit facilities and a market linkage to help villagers earn a sustainable livelihood. During fiscal 2017, we converted 100 villages into digital villages. See also “ Risk Factors—Risks Relating to Our Business— Entry into new businesses or rapid growth in existing loan portfolios may expose us to increased risks that may adversely affect our business ”.

The following table sets forth, at the dates indicated, the break-down of our gross retail finance portfolio.

Our unsecured retail portfolio primarily includes personal loans and loans against credit card receivables. Following the global financial crisis leading to increase in interest rates, tightening liquidity and challenging macro-economic environment and changes in regulations pertaining to the use of recovery agents by banks, we witnessed higher than anticipated losses in the unsecured retail portfolio. We reduced incremental lending in personal loans and credit card issuances, resulting in a decline in the overall unsecured retail lending portfolio. Since fiscal 2013, we have been growing our personal loans and credit card lending portfolio, primarily by offering these products to our existing customers. During fiscal 2017, ICICI Bank’s personal loan disbursements, at Rs.103.4 billion, were about 10.1% of total retail loan disbursements and the number of outstanding credit cards increased from around 3.7 million at year-end fiscal 2016 to about 4.3 million at year-end fiscal 2017. ICICI Bank’s personal loans typically range from Rs. 50,000 to Rs. 4,000,000 in size with tenors of one to five years and yields ranging from 11-20%. Our personal loans portfolio increased from Rs. 102.2 billion at year-end fiscal 2016 to Rs. 143.7 billion at year-end fiscal 2017. The credit card receivables portfolio increased from Rs. 55.2 billion at year-end fiscal 2016 to Rs. 75.5 billion at year-end fiscal 2017. The proportion of unsecured retail loans in the total retail portfolio was 11.1% at year-end fiscal 2017 compared to 9.1% at year-end fiscal 2016.

We offer retail lending products primarily in India through ICICI Bank and our wholly owned subsidiary, ICICI Home Finance Company Limited. Our home loan portfolio includes both loans for the purchase and construction of homes as well as loans against property. Our policies for such loans are based on certain stipulated ratios such as the loan-to-value ratio and the ratio of fixed debt obligations to a borrower’s income. In

October 2015, the Reserve Bank of India revised the loan-to-value ratios for small size loans and capped the loan-to-value ratio at 90% for home loans up to Rs. 3.0 million, and at 80% for home loans between Rs. 3.0 million and Rs. 7.5 million. Loans above Rs. 7.5 million have a maximum loan-to-value ratio of 75.0%. The initial repayment term of such loans is 15 to 20 years with payments in the form of equated monthly installments. We conduct a part of our housing loan business through ICICI Home Finance Company.

Our banking subsidiary in Canada offers residential mortgages in the local market. The mortgages are insured and primarily have federal-backed insurance. At year-end fiscal 2017, ICICI Bank Canada held total residential mortgages amounting to CAD 3,458 million (Rs. 168.0 billion) as compared to CAD 3,240 million (Rs. 166.0 billion) at year-end fiscal 2016. This includes mortgages of CAD 3,145 million (Rs. 161.0 billion) at year-end fiscal 2017 as compared to CAD 2,968 million (Rs. 152.0 billion) at year-end fiscal 2016 securitized under the Canadian National Housing Act – Mortgage Backed Securities program or through participation in the Canada Mortgage Bonds program.

Retail Deposits

Our retail deposit products include time deposits and savings account deposits. We also offer targeted products to specific customer segments such as high net worth individuals, defense personnel, trusts and businessmen. We also offer corporate salary account products and current account (i.e., checking accounts for businesses) products to our small enterprise customers, who maintain balances with us. Further, we offer an international debit card in association with VISA International. At year-end fiscal 2017, we had a debit card base in excess of 36 million cards.

We continuously focus on increasing our current and savings account deposit base and maintaining the proportion of current and savings accounts in our total deposits. Leveraging our branch network in India and on technology platforms to improve the customer experience are critical elements of our strategy. We have been expanding our offerings through mobile phones, including mobile banking applications for account access and various transactions, and a mobile wallet. We open new customer accounts by using tablets to capture customer information digitally. By offering our products and services through technology-enabled channels, we aim to improve the customer experience as well as the efficiency of our operations.

We have strengthened our capabilities in assessing credit risks across various sectors that enables us to provide customized solutions based on requirements of small and medium enterprises.

We also have specialized teams for current accounts (i.e. checking accounts), trade finance, cash management services and door-step banking. We are also proactively reaching out to small and medium enterprises through various initiatives such as the “SME toolkit” —an online business and advisory resource for

small and medium enterprises; and the “Emerging India Awards” —a small and medium enterprises recognition platform.

Commercial Banking for Corporate Customers

We provide a range of commercial and investment banking products and services to India’s leading corporations and middle market companies. Our product suite includes working capital and term loan products, fee and commission-based products and services, deposits and foreign exchange and derivatives products.

Corporate Loan Portfolio

Our corporate loan portfolio consists of project and corporate finance (including structured finance and cross-border acquisition financing) and working capital financing. For further details on our loan portfolio, see “ —Loan Portfolio—Loan Concentration ”. For a description of our credit rating and approval system, see “ —Risk Management—Credit Risk ”.

Project financing constitutes a significant portion of our loan portfolio. Our project finance business consists principally of extending medium-term and long-term rupee and foreign currency loans to the manufacturing and infrastructure sectors. We also provide financing by way of investment in marketable instruments such as fixed rate and floating rate debentures. We generally have a security interest and first charge on the fixed assets of the borrower. Our working capital financing consists mainly of cash credit facilities, overdraft, demand loans and non-fund based facilities including bill discounting, letters of credit and guarantees. For more details on our credit risk procedures, see “— Risk Management—Credit Risk ”.

From fiscal 2010, the Indian corporate sector undertook significant investments, including in the infrastructure and commodity sectors. This led to high loan growth in the banking sector, including for us. Subsequently, the Indian economy experienced challenges in terms of high inflation and consequently higher interest rates, currency depreciation and a sharp slowdown in economic growth. The corporate sector experienced a decline in sales and profit growth, an elongation of working capital cycles and a high level of receivables, including from the government, and significant challenges in project completion and cash flow generation, due to policy changes, delays in approvals like clearances on environment and land permits, and judicial decisions like the deallocation of coal mines. Indian corporations, especially in the infrastructure and industrial sectors, had limited ability to access capital in view of the economic scenario and volatility in global and domestic financial markets, corporate investment activity declined. From fiscal 2014 onwards, these developments led to an increase in non-performing and restructured corporate loans in the Indian banking sector, including for us, and a substantial moderation in overall loan growth, driven primarily by lower growth in credit to the corporate sector. The corporate sector continued to be impacted due to lower than anticipated cash flow generation and high leverage. The significant decline in global commodity prices in fiscal 2015 and fiscal 2016, including metals, coal and crude oil, negatively impacted borrowers in commodity-linked sectors. Capital investments in the economy remained subdued, impacting corporations in investment-linked sectors like construction. Due to the lower than projected cash flows, the progress in reducing leverage in the corporate sector was slow.

During fiscal 2017, the additions to non-performing loans, including slippages from restructured loans, continued to remain elevated as the corporate sector challenges continued due to the slowdown in economic growth, low corporate profitability and subdued investment activity. The slowdown in economic growth was primarily in the industrial and services sectors, with growth in the industrial sector moderating to 5.6% during fiscal 2017 compared to 8.8% during fiscal 2016, and in the services sector to 7.7% in fiscal 2017 compared to 9.7% in fiscal 2016. Further, during the second half of fiscal 2017, there was a reduction in the availability of cash caused by the withdrawal of high denomination currency notes by the government of India, which also impacted businesses. While several companies are working with banks to restructure and reorganize their businesses and reduce their leverage through sales of businesses and assets, the process of resolution of stressed assets remained slower than expected due to delays in decision making at the Joint Lenders’ Forum that were set up to explore options for early resolution of stress in loan accounts. Several measures were announced by the Reserve Bank of India and the government, including the introduction of the Insolvency and Bankruptcy Code, during the year to enable early resolution of assets. However, the continued challenges in the operating and recovery environment adversely impacted the pace of resolution leading to a significant increase in non-

performing loans, including slippages from restructured loans, during fiscal 2017. Further, in June 2017, the Reserve Bank of India directed banks to commence proceedings under the Insolvency and Bankruptcy Code, enacted in 2016, in respect of certain corporate borrowers. Under this Code, a resolution plan for these borrowers would be required to be finalized within specified timeframes, failing which the borrowers would go into liquidation. The Reserve Bank of India has also specified higher provisions in respect of loans to these borrowers, which may impact our future provisions. With respect to other identified stressed accounts, the banks are required to finalise a resolution plan within six months, failing which banks shall be required to file for insolvency proceedings under the Insolvency and Bankruptcy Code.

We have adopted a cautious approach in incremental lending by focusing on lending to higher rated corporations and adopting a revised framework for management of concentration risk. See also “ Risk Factors—Risks Relating to Our Business— If we are unable to adequately control the level of non-performing loans in our portfolio, our business will suffer” and “ Business—Strategy ” and “ Operating and Financial Review and Prospects— Executive Summary—Business environment —Trends in fiscal 2017 ”.

Fee and Commission-Based Activities

We generate fee income from our syndication, structured financing and project financing activities. We seek to leverage our project financing and structuring skills and our relationships with companies and financial institutions and banks to earn fee incomes from structuring and syndication.

We offer our corporate customers a wide variety of fee and commission-based products and services including documentary credits and standby letters of credit (called guarantees in India).

We also offer commercial banking services such as cash management services (such as collection, payment and remittance services), escrow, trust and retention account facilities, online payment facilities, custodial services and tax filing and collection services on behalf of the government of India and the governments of Indian states. At year-end fiscal 2017, total assets held in custody on behalf of our clients (mainly foreign institutional investors, offshore funds, overseas corporate bodies and depositary banks for GDR investors) were Rs. 2,262.9 billion. As a registered depositary participant of National Securities Depository Limited and Central Depository Services (India) Limited, the two securities depositaries operating in India, we also provide electronic depositary facilities to investors.

Corporate Deposits

We offer a variety of deposit products to our corporate customers including current accounts, time deposits and certificates of deposits. For more information on the type, cost and maturity profile of our deposits, see “— Business—Funding ”.

Foreign Exchange and Derivatives

We provide customer specific products and services, which cater to risk hedging needs of corporations at domestic and international locations, arising out of currency and interest rate fluctuations. The products and services include:

Products include cash, spot and forwards transactions. We offer customized hedging and trading solutions to clients, on the basis of their business needs. These products are offered in India and across our international locations.

We offer derivative products including interest rate swaps, currency swaps and options in all major currencies.

Commercial Banking for International Customers

Our strategy for growth in international markets is based on leveraging home country links and technology for international expansion in selected international markets. Our international strategy is focused on building a retail deposit franchise in geographies where we have such licenses, making loans to global multi-national corporations, meeting the foreign currency needs of our Indian corporate clients, taking select non-India trade finance exposures, and lending to corporations in the local jurisdiction. We also seek to build stable wholesale

funding sources and strong syndication capabilities to support our corporate and investment banking business, and to expand private banking operations for India-centric asset classes.

At March 31, 2017, we had subsidiaries in the United Kingdom and Canada, branches in Bahrain, Dubai International Finance Center, Hong Kong, China, Singapore, Sri Lanka, Qatar Financial Centre, South Africa and the United States and representative offices in Bangladesh, Indonesia, Malaysia and the United Arab Emirates. Our subsidiary in the United Kingdom has established a branch in Antwerp, Belgium and a branch in Frankfurt, Germany.

Many of the commercial banking products that we offer through our overseas branches and subsidiaries, as well as to international customers from our domestic network, such as debt financing, trade finance and letters of credit, are similar to the products offered to our customers in India. Some of the products and services that are unique to international customers are:

Total assets (net of inter-office balances) of ICICI Bank’s overseas branches at year-end fiscal 2017 were Rs. 946.3 billion and total advances were Rs. 749.9 billion compared to total assets of Rs. 1,188.4 billion and total advances of Rs. 938.1 billion at year-end fiscal 2016. Our overseas branches are primarily funded by debt capital market borrowings, syndicated/bilateral loans and borrowings from external commercial agencies. See also “ Risk Factors—Risks Relating to Our Business—Our funding is primarily short-term and if depositors do not roll over deposited funds upon maturity, our business could be adversely affected ”.

Our subsidiaries in the United Kingdom and Canada are full service banks offering retail and corporate banking services. These subsidiaries offer direct banking using the internet as the access channel.

Delivery Channels

We deliver our products and services through a variety of channels, ranging from traditional bank branches to ATMs, call centers, the Internet and mobiles. At year-end fiscal 2017, we had a network of 4,850 branches across several Indian states.

The following table sets forth the number of branches broken down by area at year-end fiscal 2017.

As a part of its branch licensing conditions, the Reserve Bank of India has stipulated that at least 25.0% of our banking outlets must be located in tier 5 and tier 6 centers defined on the basis of the population size according to the 2011 census. See also “ Supervision and Regulation—Regulations Relating to the Opening of Branches ”. At year-end fiscal 2017, we were in compliance with this condition. At year-end fiscal 2017, we had 13,882 ATMs, of which 4,988 were located at our branches. We view our branch as key points of customer acquisition and service. The branch network serves as an integrated channel for deposit mobilization and selected retail asset origination.

We believe that developments in technology are changing the way customers engage with banks and meet their banking needs. We offer our products and services through a number of technology-enabled channels. Our customers can perform a wide range of transactions at our ATMs. We are also deploying automated devices, such as cash acceptance machines, at our branches to improve customer experience as well as efficiency of our operations. Our employees open new customer accounts by using tablets to capture customer information digitally. Through our website, www.icicibank.com, we offer our customers, both retail and corporate, online access to account information, payment and fund transfer facilities and various other services including purchase of investment and insurance products. We provide telephone banking facilities through our call centers. We are expanding our suite of services through mobile telephones, including mobile banking applications for account access and various transactions, and a mobile wallet. Our customers can also access their accounts and perform transactions via social media platforms. During fiscal 2017, we introduced Chatbots, an artificial intelligence enabled chat feature to perform various banking transactions. We worked closely with the National Payments Corporation of India for the development of the Unified Payment Interface, a payment platform which allows instant fund transfer to any bank account using a virtual payment address, without requiring bank account details. The Unified Payment Interface has been promoted by us through various platforms, such as our mobile application and our digital wallet. We also enabled payment through the Bharat Interface for Money, a mobile application promoted by the government of India and built using the Unified Payment Interface. We further enabled payments using the Unified Payment Interface for users of the Truecaller app in India. We developed a mobile application for merchants in India, ‘Eazypay’, which allows merchants to accept payments on mobile phones through multiple modes including credit/debit cards of any bank, internet banking and our digital wallet.

Investment Banking

Our investment banking operations principally consist of ICICI Bank’s treasury operations and the operations of ICICI Securities Primary Dealership Limited and ICICI Securities Limited.

Treasury

Through our treasury operations, we seek to manage our balance sheet, including the maintenance of required regulatory reserves, and to optimize profits from our trading portfolio by taking advantage of market opportunities. Our domestic trading and securities portfolio includes our regulatory reserve portfolio, as there is no restriction on active management of our regulatory reserve portfolio. Our treasury operations include a range of products and services for corporate and small enterprise customers, such as forward contracts and interest rate and currency swaps, and foreign exchange products and services. See also “— Commercial Banking for Corporate Customers—Foreign Exchange and Derivatives ”.

Our treasury undertakes liquidity management by seeking to maintain an optimum level of liquidity and complying with the cash reserve ratio requirement and ensuring the smooth functioning of all our branches. We maintain a balance between interest-earning liquid assets and cash to optimize earnings and undertake reserve management by maintaining statutory reserves, including the cash reserve ratio and the statutory liquidity ratio. At year-end fiscal 2017, ICICI Bank was required to maintain the statutory liquidity ratio requirement percentage at 20.5% of its domestic net demand and time liabilities by way of approved securities such as government of India securities and state government securities. We maintain the statutory liquidity ratio through a portfolio of government of India securities that it actively manages to optimize the yield and benefit from price movements. Further, as a prudent liquidity management strategy, we generally maintain excess investments in securities eligible for classification under the statutory liquidity ratio requirement. See also “ Supervision and Regulation—Legal Reserve Requirements ”.

ICICI Bank engages in domestic investments and foreign exchange operations from a centralized trading floor in Mumbai. As a part of our treasury activities, we also maintain proprietary trading portfolios in domestic debt and equity securities and in foreign currency assets. Our treasury manages our foreign currency exposures and the foreign exchange and risk hedging derivative products offered to our customers and engages in proprietary trading in currencies. Our investment and market risk policies are approved by the Board of Directors.

ICICI Bank’s domestic investment portfolio is classified into three categories —held-to-maturity, available-for-sale and held-for-trading. Investments are classified as held-to-maturity subject to the current regulation issued by the Reserve Bank of India. Investments acquired by us with the intention to trade by taking advantage of the short-term price/interest rate movements are classified as held-for-trading. The investments which do not fall in the above two categories are classified as available-for-sale. Investments under the held-for-trading category should be sold within 90 days. Under each category the investments are classified under (a) government securities (b) other approved securities (c) shares (d) bonds and debentures (e) subsidiaries and joint ventures and (f) others. Investments classified under the held-to-maturity category are not marked to market and are carried at acquisition cost, unless the acquisition cost is more than the face value, in which case the premium is amortized over the period until maturity of such securities. At year-end fiscal 2017, 74.2% of ICICI Bank’s government securities portfolio was in the held-to-maturity category. Any premium over the face value of investments in government securities, classified as available-for-sale, is amortized over the period until maturity of such securities. The individual securities in the available-for-sale category are marked to market. Investments under this category are valued security-wise and depreciation/appreciation is aggregated for each classification. Net depreciation, if any, is provided for. Net appreciation, if any, is ignored. The individual securities in the held-for-trading category are accounted for in a similar manner as those in the available-for-sale category.

The following tables set forth, at the dates indicated, certain information related to our available-for-sale investments portfolio.

The investments in corporate debt securities decreased from Rs. 118.8 billion at year-end fiscal 2016 to Rs. 73.8 billion at year-end fiscal 2017, primarily due to a decrease in investment in corporate bonds and debentures. The investment in government securities increased from Rs. 246.8 billion at year-end fiscal 2016 to Rs. 287.7 billion at year-end fiscal 2017 primarily due to an increase in investment in government securities by ICICI Bank. Investments in other debt securities increased from Rs. 110.4 billion at year-end fiscal 2016 to Rs. 166.7 billion at year-end fiscal 2017, primarily due to an increase in investment in pass through certificate securities with underlying Indian receivables by ICICI Bank. Investments in equity shares increased from Rs. 63.8 billion at year-end fiscal 2016 to Rs. 86.1 billion at year-end fiscal 2017 primarily due to an increase in the equity portfolio of ICICI Bank, ICICI Prudential Life Insurance Company and ICICI Lombard General Insurance Company. Other investments increased from Rs. 23.7 billion at year-end fiscal 2016 to Rs. 68.6 billion at year-end fiscal 2017 primarily due to an increase in investment in security receipts issued by asset reconstruction companies and investments in liquid mutual funds by ICICI Prudential Life Insurance Company.

Net unrealized gain on debt investments increased from Rs. 2.5 billion at year-end fiscal 2016 to Rs. 3.6 billion at year-end fiscal 2017 primarily due to an increase in net unrealized gain on corporate debt securities and government securities.

Interest and dividend income from our available-for-sale securities portfolio increased from Rs. 31.9 billion in fiscal 2016 to Rs. 36.2 billion in fiscal 2017. The net realized gain from our available-for-sale securities increased from Rs. 4.4 billion in fiscal 2016 to Rs. 11.8 billion in fiscal 2017 primarily due to higher net realized gains from the equity and fixed income portfolios. In fiscal 2017, equity market improved and yield on securities declined resulting in better opportunities to realize gains on these securities.

The following table sets forth, at the date indicated, an analysis of the maturity profile of our investments in debt securities classified as available-for-sale investments, and yields thereon. This maturity profile is based on repayment dates and does not reflect re-pricing dates of floating rate investments.

The amortized cost of our held-to-maturity portfolio decreased marginally from Rs. 1,226.0 billion at year-end fiscal 2016 to Rs. 1,223.0 billion at year-end fiscal 2017 primarily due to a decrease in investment in government securities, commercial papers and certificate of deposits, offset, in part, by an increase in corporate debt securities. Net unrealized gain on held-to-maturity portfolio increased from Rs. 14.5 billion at year-end fiscal 2016 to Rs. 34.9 billion at year-end fiscal 2017 primarily due to an increase in unrealized gain on government securities. Unrealized gains on government securities increased primarily due to a decline in yield on government securities. The yield on the benchmark 10-year Government securities decreased from 7.4% at March 31, 2016 to 6.7% at March 31, 2017. Interest income on held-to-maturity debt portfolio increased from Rs. 93.5 billion in fiscal 2016 to Rs. 97.1 billion in fiscal 2017 due to an increase in average investment portfolio in held-to-maturity category in fiscal 2017 as compared to fiscal 2016.

Investments in held-for-trading securities decreased from Rs. 308.4 billion at year-end fiscal 2016 to Rs. 239.2 billion at year-end fiscal 2017 primarily due to a decrease in investment in government securities and certificate of deposit, offset, in part, by an increase in investment in corporate bonds and debentures. Interest and dividend income on held-for-trading securities increased from Rs. 17.8 billion in fiscal 2016 to Rs. 21.3 billion

in fiscal 2017. Net realized and unrealized gains on the held-for-trading portfolio increased from Rs. 1.8 billion in fiscal 2016 to Rs. 9.1 billion in fiscal 2017 primarily due to higher realized/unrealized gains on government and other domestic fixed income securities reflecting higher trading opportunities in fiscal 2017.

At year-end fiscal 2017, we have investments in equity shares amounting to Rs. 108.2 billion. The Reserve Bank of India restricts investments in equity securities by banks by prescribing limits linked to capital funds. See also “ Supervision and Regulation—Reserve Bank of India Regulations—Regulations Relating to Investments and Capital Market Exposure Limits ”.

In general, we pursue a strategy of active management of our long-term equity portfolio to maximize our return on investment. To ensure compliance with the Securities and Exchange Board of India’s insider trading regulations, all dealings in our equity and debt investments in listed companies are undertaken by our treasury’s equity and corporate bonds dealing desks, which are segregated from both the other groups and desks in the treasury and from our other business groups, and which do not have access to unpublished price sensitive information about these companies that may be available to us as a lender.

We deal in several major foreign currencies and take deposits from non-resident Indians in major foreign currencies. We also manage onshore accounts in foreign currencies. The foreign exchange treasury manages our portfolio through money market and foreign exchange instruments to optimize yield and liquidity.

We provide a variety of risk management products to our corporate and small and medium enterprise clients, including foreign currency forward contracts and currency and interest rate swaps. We control market risk and credit risk on our foreign exchange trading portfolio through an internal model which sets counterparty limits, stop-loss limits and limits on the loss of the entire foreign exchange trading operations and exception reporting.

Through our branches and subsidiaries outside India and our offshore banking unit in Mumbai, we have made investments in corporate and financial sector bonds and debt securities and mortgage and asset backed securities outside India.

The following table sets forth, at the date indicated, investments in corporate and financial sector debt securities and mortgage and asset backed securities by our overseas branches and banking subsidiaries by region and the mark-to-market and realized losses thereon.

Investments in corporate and financial sector debt securities and mortgage and asset backed securities by our overseas branches and banking subsidiaries decreased from Rs. 102.7 billion at year-end fiscal 2016 to Rs. 79.1 billion at year-end fiscal 2017 primarily due to a decrease in investments in bonds held by our Canadian subsidiary due to call back/maturity of bonds. At year-end fiscal 2017, our investments in Europe were Rs. 4.2 billion as compared to Rs. 8.3 billion at year-end fiscal 2016. The majority of our investments in Europe are in the United Kingdom.

The following table sets forth a summary of the investment portfolio of our overseas branches and banking subsidiaries based on the category of investments.

Our investments in securities of banks and financial institutions are spread over a number of banks and of this the investment in the top 10 banks accounted for approximately 94.6% of the total investments in banks and financial institutions at year-end fiscal 2017 as compared to approximately 89.2% at year-end fiscal 2016.

The bond portfolio decreased from Rs. 96.4 billion at year-end fiscal 2016 to Rs. 73.0 billion at year-end fiscal 2017 primarily due to call-back/maturity of bonds held by our Canadian subsidiary. Our total investment in asset backed securities represents less than 0.5% of our total assets at year-end fiscal 2017. The portfolio size of such securities was Rs. 2.8 billion and primarily comprised retail mortgage backed securities.

The investments in these securities are governed by the respective investment policies of ICICI Bank and its banking subsidiaries. To mitigate significant concentrations in credit risk, the investment policy lays down a number of limits that need to be adhered to before investments can be made. The investment policy lays down rating and issuer wise investment limits at each of these units. Further, there are counterparty limits for individual banks and financial institutions. Country exposure limits have also been established for various countries. In addition, ICICI Bank monitors the credit spread risk arising out of such investments while ICICI Bank UK has instituted credit spread sensitivity limits on its portfolio. Any exceptions to the above limits are made with due approvals from the appropriate forums. ICICI Bank has not bought credit protection against any of its international investments.

ICICI Lombard General Insurance Company was formed as a joint venture with Fairfax Financial Holdings of Canada. The joint venture was terminated on July 3, 2017.

In fiscal 2015, the Indian parliament approved legislation increasing the foreign shareholding limit in the insurance sector from 26.0% to 49.0%, and removing the requirement that promoters of insurance companies eventually reduce their shareholding to 26.0% following the completion of 10 years of commencement of business by the insurance company. Final regulations were issued by the government of India in fiscal 2016. Subsequently, we sold approximately 6.0% stake in our life insurance subsidiary, ICICI Prudential Life Insurance Company, during fiscal 2016. In September 2016, we sold a further 12.63% out of our shareholding in ICICI Prudential Life Insurance Company through an offer for sale in an initial public offering of the company’s shares. ICICI Prudential Life Insurance Company was listed on the National Stock Exchange of India Limited and BSE Limited on September 29, 2016. After this sale, our share ownership in ICICI Prudential Life Insurance Company came down from approximately 74% to approximately 55%.

The Insurance Regulatory and Development Authority of India had invited six life insurance companies, including our life insurance subsidiary, to assess their interest in taking over the liabilities of policyholders’ along with the corresponding assets of Sahara India Life Insurance Company Limited. Our life insurance subsidiary had accordingly made a proposal and subsequently received the order from the Insurance Regulatory and Development Authority of India to takeover the life insurance portfolio of Sahara India Life Insurance Company Limited on July 28, 2017. This transaction will be considered as a transfer, not a merger, of the life insurance portfolio and is less than 1.0% of our life insurance subsidiary’s balance sheet. Sahara India Life Insurance Company has appealed against the order.

We also sold a 9.0% stake in our general insurance company, ICICI Lombard General Insurance Company, to our then joint venture partner, Fairfax Financial Holdings (through its affiliate), during fiscal 2016. Following the transaction, the share ownership in ICICI Lombard General Insurance Company of ICICI Bank and Fairfax Financial Holdings Limited were approximately 64% and 35%, respectively.

In pursuance of the proposed initial public offering, on July 3, 2017 our joint venture agreement with Fairfax Financial Holdings was terminated with provisions for protection of the parties in the event of non-completion of the proposed initial public offering within the timelines specified in the termination agreement. ICICI Lombard General Insurance Company has filed a draft red herring prospectus with the Securities and Exchange Board of India for the proposed public offering. The Bank will continue to hold more than 50.0% shareholding in the general insurance subsidiary post the proposed initial public offer.

In fiscal 2010, the Insurance Regulatory and Development Authority of India changed the regulations relating to unit-linked life insurance products. Subsequently, the Insurance Regulatory and Development Authority of India also issued revised regulations relating to non-linked life insurance products, which became effective during fiscal 2014. The key changes related to commissions payable to agents and distributors, lapse of policies, surrender values and minimum death benefits. As a result of these changes, the life insurance sector experienced low growth and changes in the product mix in recent years, as life insurance companies were required to modify their products and distribution strategies. While there was initially a shift in the product mix towards non-unit linked products, more recently the share of unit-linked products has increased primarily due to favorable cost structures of these products from a customer perspective, as well as improved capital market conditions. Linked products contributed to 84.1% of the annualized premium equivalent of ICICI Prudential Life Insurance Company in fiscal 2017 compared to 80.8% in fiscal 2016 and 83.1% in fiscal 2015. See also “ Risk Factors – Risks Relating to Our Business – While our insurance businesses are an important part of our business, there can be no assurance of their future rates of growth or levels of profitability ” and “ Operating and Financial Review and Prospects – Segment Revenues and Assets – Life Insurance ”. Further, the Insurance

Regulatory and Development Authority of India has issued guidelines on bancassurance (i.e., the practice of banks selling insurance products in a marketing arrangement with insurance companies). As per the guidelines, banks can align with three insurance companies each in life, non-life and health insurance sectors.

ICICI Bank earns commissions and fees from these subsidiaries as a distributor for sales of life and general insurance products.

Funding

Our funding operations are designed to ensure stability of funding, minimize funding costs and effectively manage liquidity. Our primary source of domestic funding is deposits raised from both retail and corporate customers. We also raise funds through short-term rupee borrowings and domestic or overseas bond offerings. Our domestic bond borrowings include long-term bond borrowings for financing infrastructure projects and low-cost housing in accordance with the Reserve Bank of India guidelines.

Our overseas branches are primarily funded by bond issuances, syndicated loans from banks, money market borrowings, inter-bank bilateral loans and borrowings from external commercial agencies. See also “ Risk Factors—Risks Relating to Our Business—Our funding is primarily short-term and if depositors do not roll over deposited funds upon maturity, our business could be adversely affected ”. Our subsidiaries in the United Kingdom and Canada fund themselves primarily through retail deposits. Our Canadian subsidiary also funds itself through securitization of insured mortgages.

Our deposits were 52.0% of our total liabilities at year-end fiscal 2017 compared to 49.1% of our total liabilities at year-end fiscal 2016. Our borrowings were 19.1% of our total liabilities at year-end fiscal 2017 compared to 24.0% of our total liabilities at year-end fiscal 2016. Our deposits increased by 13.6% from Rs. 4,510.8 billion at year-end fiscal 2016 to Rs. 5,125.9 billion at year-end fiscal 2017. Our borrowings decreased by 14.6% from Rs. 2,203.8 billion at year-end fiscal 2016 to Rs. 1,882.9 billion at year-end fiscal 2017 primarily due to a decrease in call and term money borrowings, refinance borrowings, borrowings with the Reserve Bank of India under liquidity adjustment facility and subordinated bond borrowings, offset, in part, by an increase in bond borrowings.

The following table sets forth, at the dates indicated, the composition of deposits by type of deposit.

The following table sets forth, for the periods indicated, the average volume and average cost of deposits by type of deposit.

Our average deposits increased from Rs. 3,940.5 billion at an average cost of 5.6% in fiscal 2016 to Rs. 4,498.2 billion at an average cost of 5.2% in fiscal 2017 primarily due to significantly higher current account and savings account deposit inflows in the second half of fiscal 2017 following the withdrawal of legal tender status of high denomination currency notes by the government of India. Our average time deposits increased from Rs. 2,348.3 billion at an average cost of 7.4% in fiscal 2016 to Rs. 2,546.9 billion at an average cost of 6.9% in fiscal 2017. The cost of time deposits decreased from 7.4% in fiscal 2016 to 6.9% in fiscal 2017 primarily due to a reduction of term deposit rates by ICICI Bank on select maturities reflecting the softening of interest rates in India. Our savings deposits include retail savings deposits accepted by ICICI Bank UK PLC. See also “ Operating and Financial Review and Prospects—Financial Condition—Deposits ”.
