Managerial Income Statement

In this report, besides the adjustment of non-recurring events, we apply managerial criteria to present our income statement. In relation to the accounting statement, these criteria affect the breakdown of our income statement but not the net income. Among the managerial adjustments, we highlight the tax effects of the hedge of investments abroad - originally included in tax expenses (PIS and COFINS) and income tax and social contribution on net income, which are reclassified to the financial margin. These reclassifications enable us to carry out business analyses from the management viewpoint and are shown in the table on the following page (Accounting and Managerial Statements Reconciliation) of this report.

In relation to the hedge of investments abroad, our strategy for foreign exchange risk management is aimed at mitigating, through financial instruments, the effects of foreign exchange variations and includes the impact of all tax effects. We present below the foreign exchange variation of the Brazilian real:

Results

| Recurring Net Income

| Income Before Tax and Minority Interests

Performance:

Recurring net income for the third quarter of 2018 amounted to R$6.5 billion, a 1.1% increase from the previous quarter, with return on average equity of 21.3%.

The highlights of the quarter were the lower cost of credit and the increase in the financial margin with clients. These positive effects were partially offset by the increase in non-interest expenses. However, it is worth mentioning that the growth in non-interest expenses was driven by the growth of commercial teams, particularly for the branch network, insurance and acquiring operations. There was also the seasonal impact of the collective labor agreement and the effect of the foreign exchange variation in the period in our expenses on Latin America.

In relation to the result of the first nine months of 2018, we highlight the 10.1% increase in income before taxes and minority interests, compared to the same period of the previous year. The lower cost of credit and higher commissions and fees were the main drivers for this performance. This performance was partially offset by the recognition of deferred tax assets at a rate of 40%, in line with current legislation, which temporarily increased our effective tax rate in 2018. The combination of these factors resulted in a 3.5% increase in our year-to-date recurring net income compared to the same period of the previous year.

Loan portfolio grew 2.1% in the quarter and 10.6% year-on-year, and our delinquency ratios continue to improve both for individuals and very small, small and middle-market companies in Brazil.

Events in the quarter

Changes in the Executive Committee

We announced changes in the executive committee that will come into effect as from January 2019. Eduardo Vassimon, Wholesale General Director, reached the age limit for exercising the duties of this position and will be replaced by the current Vice President of Risk and Finance Control Area, Caio Ibrahim David. Milton Maluhy Filho will take up the position of Vice President of Risk and Finance Control Area.

Acquisition of minority interest in XP Investimentos

On August 10, 2018, we obtained the authorization from the Central Bank of Brazil to invest in XP Investimentos. In the first phase, we acquired 49.9% of XP Holding’s total capital by means of a capital increase in the amount R$600 million and the acquisition of shares in the amount of R$5.7 billion. The first acquisition was completed on August 31, 2018. This operation should not have any significant impacts on this year’s financial results and the impact of the first acquisition on our Basel ratio was 90 basis points.

Itaú CorpBanca

In accordance with the Announcement to the Market of October 12, 2018, we announced the indirect acquisition of Itaú CorpBanca shares for the approximate amount of R$365 million, as a result of Corp Group exercising a put option set forth in the stockholders’ agreement of April 1, 2016. Therefore, our interest ownership in Itaú CorpBanca increased to 38.14%, from 36.06%, without changing the governance of Itaú CorpBanca.

Highlights in 3Q18

Financial Margin with Clients

In this quarter, the 1.2% increase in our financial margin with clients was due to the positive impacts of the better mix of products and of the higher number of calendar days compared to the previous quarter. These positive effects were partially offset by the reduction in spreads (mainly in overdraft).

In the first nine months of 2018, the better mix of products and the increase in the volume of loans more than offset the negative effects of the interbank deposit rate decrease on our liabilities financial margin and working capital and the reduction in spreads.

Further details on page 16

Cost of Credit

The decrease of 9.4% in our cost of credit in the quarter was driven by lower provisions for loan losses. In the Wholesale Banking in Brazil, we had reversal of provisions mainly due to risk rating improvement of a specific client. This positive variation was partially offset by the natural increase in Retail Banking expenses in Brazil, related to the segment loan portfolio growth.

In the first nine months of 2018, the reduction in cost of credit is related to the improvement of the credit quality of the portfolio in Brazil, both in the Retail and in Wholesale Banking segments.

Further details on pages 18-19

Commissions, Fees and Result from Insurance 1

In the quarter there was a decrease of 2.1% in commissions, fees and result from insurance. The decrease in commissions and fees is related to lower income from advisory services and brokerage that was partially offset by the increase in credit card revenues. The lower result in our insurance operations is related to the liability adequacy test revenue recognized in the second quarter.

In the first nine months of 2018 commissions, fees and result from insurance operations increased 6.5%. We highlight the increases in fund management fees, driven by higher volume of assets managed, and in current account services, due to the higher number of current account holders in the period.

Further details on pages 23-28

Non-Interest Expenses

The increase of 3.1% in non-interest expenses in the quarter was driven by higher personnel expenses, impacted by the collective labor agreement and the increase in the number of employees. There was also an increase in our expenses in Latin America (ex-Brazil) impacted by the foreign exchange variation in the period.

In the first nine months of 2018, non-interest expenses increased 6.4%, whereas expenses in Brazil (ex-Citibank) increased 0.9% from the same period of the previous year, below inflation for the period.

Highlights in 3Q18

Credit Portfolio with Financial Guarantees Provided and Corporate Securities

The increase in the loan portfolios for very small, small and middle-market companies and for individuals, both in the third quarter and in the year, was driven by higher credit demand from our clients.

The 1.6% decrease in the corporate loan portfolio in the quarter was due to the low demand for long-term credit, which migrated to the capital markets.

NPL Ratio (%) | over 90 days

The NPL ratio increase is associated with the delinquency of large companies in Brazil. This increase in the delinquency ratio of large companies was driven by the rollover of loans that were overdue between 15 and 90 days in the previous quarter that migrated to loans 90 days overdue and were already adequately provisioned. There was no concentration in a specific client or sector. However, it is worth mentioning the 30 basis point decrease in this ratio for very small, small and middle-market companies portfolio in Brazil.

In Latin America, the reduction was mainly driven by Chilean operations for both individuals and companies.

Further details on pages 20-22

Coverage Ratio | 90 days

The decrease in the coverage ratio in the quarter was related to the corporate segment in Brazil. This decrease in the corporate segment was due to the improvement of risk rating of an specific client that allowed the reversal of provisions for loan losses. In addition, certain clients became overdue and were already adequately provisioned.

Further details on pages 20-22

NPL Creation

The increase from the previous quarter was driven by the higher portfolio of loans more than 90 days overdue in the Wholesale Banking segment in Brazil with no concentration in a specific client or sector, that were already adequately provisioned.

Sustainability

Integration of environmental, social and governance aspects into business

Financial institutions act as intermediaries of the global economy and, therefore, we play a significant role in the transformation of society. We understand that integrating ESG aspects into our business, in addition to mitigating risks, is vital to foster social and economic development in locations where our services are offered.

Analysis methodology for ESG evaluation in investments

Credit

The management of environmental and social risks in credit aims at identifying, measuring, mitigating and monitoring risks associated to social and environmental aspects in our business.

In 2017, we assigned approximately R$2.9 billion for loan operations that promote social and environmental benefits through our corporate segment.

Investments

Using our ESG integration methodology, we analyzed 99% of the companies listed on B3, and the ones that make up the IBrX-100 index and the Corporate Sustainability Index (ISE) of B3. 90% out of the corporate fixed-rate securities are also covered by the methodology.

TCFD: Task Force on Climate-Related Financial Disclosures

Climate risk and its variables are also covered by Itaú Unibanco’s risk analysis. This approach enables us to be in a strategic position to ensure the continuity of business and operations in view of climate change and the resulting impacts on the economy expected for the coming years.

In the beginning of 2018, a multidisciplinary working group was created to implement the recommendations of the document disclosed by the Financial Stability Board, “Task Force on Climate Finance Disclosure” (TCFD), and, in line with this topic, we created a Climate Finance agenda. This initiative encourages organizations from different sectors to get to know the physical climate risks, the ones created by them and the transition ones to which they are exposed, and proposes voluntary and consistent financial reporting related to climate, to ensure higher transparency to enable lenders, insurance companies and investors to make better business decisions.

Ecoefficiency

We are constantly focused on the management and rational use of natural resources, a strategy that allows the reduction of the environmental impact of our operations and the increase of our operational efficiency.

Transparency of social, environmental and governance data is a fundamental assumption for a sustainable performance. Our Integrated Report and Annual Report bring about information on our operations and may be accessed on www.itau.com.br/annual-report.

Managerial Financial Margin

Highlights

| · | Financial margin with clients increased in the quarter driven by the positive impact of the mix of products and higher number of calendar days in the quarter.

| · | The risk-adjusted financial margin with clientes rate increased by 10 basis points due to the reduction of the cost of credit.

Financial Margin with Clients

Financial margin with clients comprises our spread-sensitive operations, working capital and others. Spread-sensitive operations are: (i) the assets margin, that is the difference between the amount received in loan operations and corporate securities and the cost of money charged by treasury banking and (ii) the liabilities margin, which is the difference between the cost of funding and the amount received from treasury banking. Working capital margin is the interest on working capital at the Selic interest rate.

Change in the Financial Margin with Clients Breakdown

(1) Change in the composition of assets with credit risk between periods. (2) Considers credit and private securities portfolio net of more than 60 days overdue balance and balances do not include the effects of foreign exchange rate variations and spreads variation of assets with credit risk between periods.

| 1 | Mix of products (+ R$187 million): the increase in portfolios for individuals and very small, small and middle-market companies contributed to a higher share of products of these segments, such as personal loans, in the total financial margin with clients. The higher share of these products with higher spread gave rise to an increase in the margin with clients.

| 2 | Average asset portfolio, assets spreads and liabilities margin (- R$144 million): spread reduction in products, such as overdraft and working capital, was partially offset by the 0.3% growth in the average portfolio and the positive effect on liabilities margin from one additional business day in the quarter.

| 3 | Higher number of calendar days (+ R$122 million): in the third quarter of 2018, we had one additional calendar day compared to the previous quarter. Calendar days are used because most of our portfolio considers fixed rates.

| 4 | Working capital and other (+ R$17 million): associated with the increased average working capital balance.

| 5 | Financial margin with clients in Latin America (+ R$59 million): gains from foreign exchange variation and increase in the liabilities margin in this quarter.

Cost of Credit

Highlights

| · | The cost of credit decrease of 9.4% in the quarter was concentrated in the Wholesale Banking in Brazil. In this segment there was a reversal of provision for loan losses, due to the improved risk rating of a specific client.

| · | Compared to the first nine months of 2017, the cost of credit decreased R$3,094 million, mainly driven by a lower provision for loan losses and a decreased impairment of corporate securities of the Wholesale Banking in Brazil.

Compared to the previous quarter, cost of credit reduced mainly due to a lower provision for loan losses in the amount of R$367 million, mainly driven by the improved risk rating of a specific Wholesale Banking client in Brazil. Income from recovery of loans written off as losses increased by R$70 million, concentrated in Latin America.

Comparing the first nine months of 2018 with the same period of the previous year, the lower cost of credit was mainly driven by the reduction of R$2,480 million in provision for loan losses in Brazil, both in the Retail (R$182 million) and in the Wholesale Banking (R$2,298 million), in line with the improved credit quality of the portfolio. Additionally, impairment charges on corporate securities in the Wholesale Banking in Brazil decreased by R$535 million and income from recovery of loans written off as losses increased by R$296 million, mainly in the Wholesale Banking in Brazil.

The ratio of cost of credit over total risk reached 2.1%. This is the lowest level since 2014.

· Retail Banking - Brazil: the growth of the loan portfolio led to the natural increase of R$206 million in provision for loan losses in the quarter.

Recovery of Loan Written off as Losses

The increase of R$70 million was driven by Latin America operations. In the third quarter of 2018, we recorded sales of R$2.8 billion of credits that had already been written off as losses. This operation had a positive impact of R$47 million on recovery of loans written off as losses and of R$26 million on recurring net income.

Loan Portfolio by Risk Level

Allowance for Loan Losses and for Financial Guarantees Provided

There was a reduction of 1.7% in the allowance for loan losses and for financial guarantees provided compared to the end of June 2018. This reduction was in the Wholesale Banking in Brazil, driven by the improved risk rating of a specific segment client, which affected the provision for financial guarantees provided. Also worth mentioning is the migration of the balance of the additional allowance to the specific provision in the Wholesale Banking in Brazil.

We present below the total allowance(*) allocation by type of risk:

Overdue Risk: Allowances for overdue loans, as required by the Brazilian Central Bank, related to the minimum provision required for overdue operations according to CMN Resolution No. 2,682/1999. We also present the amount for loans 100% provisioned and for loans that do not require 100% of provision.

Aggravated Risk: Allowances for overdue loans with aggravated risk ratings above the minimum required by the Brazilian Central Bank, and allowances for renegotiated loans. Regarding renegotiated loans, we segregate allowances over the minimum required by the Brazilian Central Bank for overdue operations and allowances for non-overdue operations.

Potential Risk: Allowances for expected losses related to Retail Banking operations and allowances for potential losses related to Wholesale Banking operations, which includes allowance for financial guarantees provided.

¹ Includes units abroad ex-Latin America. ² Excludes Brazil. ³ Allowance for potential losses includes the allowance for financial guarantees provided. (*) Total allowance includes the allowance for loan losses and the allowance for financial guarantees provided, which totaled R$1,269 million in September 2018 and is recorded in liabilities in accordance with CMN Resolution No. 4,512/16.

Credit Quality

Highlights

| · | Nonperforming loans 90 days overdue ratio (NPL 90) increased 10 basis points. This was related to the 50 basis points increase in the corporate segment that was partially offset by a new reduction in very small, small and middle-market companies. The individuals segment NPL 90 ratio remained stable.

| · | Nonperforming loans between 15 to 90 days overdue ratio (NPL 15 - 90) decreased in all segments in Brazil. The ratio increase in Latin America operations was mainly in the companies portfolios in Chile and Colombia.

Nonperforming Loans

· Nonperforming loans - 90 days - Total: the 1.7% increase from the same period of the previous year was mainly driven by the rollover of loans of the corporate segment that were overdue between 15 and 90 days in the previous quarter, which were adequately provisioned.

NPL Ratio (%) | over 90 days

Analysis of the quarterly change in NPL 90 (%) | Credit Quality x Volume

· Consolidated: increased from the previous quarter, driven by the corporate segment in Brazil.

· Brazil1: the ratio increased from the previous quarter, driven by higher delinquency rate in the Corporate segment, due to the rollover of loans overdue between 15 and 90 days in the previous quarter.

· Latin America2: decreased in the quarter, mainly driven by the Chilean operations both for individuals and companies.

NPL Ratio - Brazil1 (%) | over 90 days

Analysis of the quarterly change in NPL 90 (%) | Credit Quality x Volume

· Individuals: the increase in nonperforming loans balance remains in line with the portfolio increase, with the ratio close to the lowest level since the merger between Itaú and Unibanco.

· Very small, small and middle-market companies: decreased for the 8th consecutive quarter, reaching the lowest level since the merger between Itaú and Unibanco, due to the quality of recent vintages.

· Corporate: increased from the previous quarter, driven by the rollover of loans overdue between 15 and 90 days that were adequately provisioned. There was no concentration in a specific client or sector.

NPL Ratio (%) | 15 to 90 days

* Note: Total and Latin America NPL Ratio (15-90 days) prior to June 2016 do not include CorpBanca.

Analysis of the quarterly change in NPL 15-90 (%) | Credit Quality x Volume

· Consolidated: the ratio decreased from the previous quarter, since the increase in Latin America was more than offset by the reduction in Brazil.

· Brazil1: decreased from the previous quarter, with lower delinquency rates in all segments.

· Latin America2: increased in the quarter, mainly in companies in Chile and Colombia.

NPL Ratio - Brazil1 (%) | 15 to 90 days

Analysis of the quarterly change in NPL 15-90 (%) | Credit Quality x Volume

· Individuals: delinquency rates decreased in the quarter, with highlights going to the credit card, personal loans and vehicles portfolios that experienced increase in credit and decrease in nonperforming loans.

· Very small, small and middle-market companies: decreased for the 4th consecutive quarter, reaching the lowest level since the merger between Itaú and Unibanco, due to the better quality of recent vintages.

· Corporate: decreased from the previous quarter, driven by the rollover of clients in that segment to the portfolio of loans more than 90 days overdue.

Coverage Ratio | 90 days

(i) Excluding the exposure of a corporate client, the Total coverage ratio would have been 244% and the Wholesale Banking in Brazil coverage ratio would have been 845%.

· Consolidated: coverage ratio decreased in the quarter, driven by the Wholesale Banking in Brazil, with improved risk rating of a specific segment client, in addition to the rollover of loans overdue between 15 and 90 days in the previous quarter that were adequately provisioned.

¹ Includes units abroad ex-Latin America.

Loan Portfolio Write-Off

(*) Loan portfolio average balance for the previous two quarters.

Loan portfolio write-offs decreased 7.4% from the previous quarter, mainly in the Retail Banking in Brazil. The ratio of written-off operations to the average balance of the loan portfolio remains consistent with the last quarters.

NPL Creation

(i) Excluding the exposure of a corporate cliente, the Total NPL Creation would have been R$4,471 million and the Wholesale Banking in Brazil NPL Creation would have been R$578 million.

Note: The NPL Creation is the balance of loans that became overdue for more than 90 days in the quarter.

· Consolidated: increased compared to the previous period, driven by the increase in the portfolio of loans more than 90 days overdue in the Wholesale Banking in Brazil, in operations that were adequately provisioned, with no concentration in a specific client or sector.

NPL Creation Coverage

Note: NPL Creation coverage ratio is calculated from the division of provision for loan losses by NPL Creation in the quarter.

In the third quarter of 2018, total NPL Creation coverage reached 79%, driven by the increase in NPL Creation and the decrease in provision for loan losses in the quarter. It is worth mentioning that the expected loss model includes provisions not only for operations with incurred losses, but also for operations that have not incurred losses yet.

· Retail Banking - Brazil: the NPL Creation coverage level reached 104%, in line with the historical levels.

· Wholesale Banking - Brazil: the NPL Creation coverage ratio was impacted by the increase in NPL Creation of the segment, in operations that were adequately provisioned, in addition to the improvement of the risk rating of a specific client that affected the provision for financial guarantees provided.

Renegotiated Loans Operations

Renegotiated loans are all types of renegotiation, either overdue, non-overdue or from loans written off as losses.

| · | The increase in renegotiated loans operations from the previous quarter is associated with some corporate operations, which were already adequately provisioned.

| · | The increase in total renegotiated loans portfolio 90-day NPL is also related to corporate segment, with no significant changes in coverage level, since the credits already had an adequate level of provisioning.

Commissions and Fees and Result from Insurance Operations1

Highlights

| · | A 2.1% decrease in the quarter, driven by the decrease in income from advisory services and brokerage, related to the lower market capital activity, and decrease in income from insurance operations. The decrease in income from insurance operations was due to the positive effect in the second quarter of 2018 related to the Liability Adequacy Test, which did not happen again in this quarter.

| · | Compared to the first nine months of 2017, the R$1,869 million increase was mainly driven by: (i) fund management fees, driven by the increase in the balance of investment funds and managed portfolios; (ii) current account services, due to the increase in the number of current account holders, in addition to the incorporation of Citibank´s retail operations; and (iii) credit card fees, due to the increased number of clients and transaction volume.

Credit Cards

Credit card revenues increased R$119 million from the previous quarter, driven by increased interchange revenues and lower expenses on rewards programs. These effects were partially offset by lower revenues from rental of machines.

Compared to the first nine months of 2017, card revenues increased 3.2% driven by higher revenues from interchange, annuity fees and the integration of Citibank’s retail operations in Brazil. These effects were partially offset by lower revenues from rental of machines and MDR (Merchant Discount Rate).

Revenues | Acquiring and Issuance Services

· Card Issuance Activities

We are the leading player in the Brazilian credit card market, totaling approximately 31.6 million (in number of accounts) credit cards and 27.5 million (in number of accounts) debit cards.

We operate through Itaucard, Hipercard, Hiper, Credicard, joint ventures and commercial agreements with leading companies in sectors such as telecom, vehicles, retail and aviation operating in the Brazilian market.

Note: Debit cards include account holders only.

· Acquiring Activities

Our merchant acquiring business comprises the process of capturing transactions through affliation, management and relationship with merchants.

In the third quarter of 2018, the volume of credit and debit card transactions increased 7.4% from the previous quarter. Compared to the same period of the previous year, the 14.0% increase was driven by the market expansion at the end of the previous year.

Equipment Base

The increase in the equipment base due to the launch of the Pop Credicard was partially offset by the migration to non-POS solutions and the competition increase in the segment, influenced by the market opening.

Current Account Services

In the third quarter of 2018, revenues from current account services remained stable from the previous quarter.

Compared to the first nine months of 2017, these revenues increased 8.7% driven by higher number of current-account holders, in addition to the incorporation of Citibank´s retail operations.

Asset Management

· Fund Management

Fund management fees were lower by R$52 million in the quarter, driven by lower revenues from performance fees, partially offset by the 4.2% increase in assets under administration and higher number of business days.

Compared to the first nine months of 2017, fund management fees grew R$543 million, mainly driven by a 15.9% increase in AuM and by higher revenues with performance fees.

According to ANBIMA, in September 2018 we ranked second in fund management and managed portfolio*, with a 22.6% market share.

* Includes Itaú Unibanco and Intrag.

Portfolio Managed and Investment Fund

Note: It includes the open platform balance and does not include Latin America (ex-Brazil). As from the third quarter of 2017, we deconsolidated managed portfolios from the Itaú group, and, for comparison purposes, the previous quarters were reprocessed.

In September 2018, we reached approximately 393 thousand active contracts, down 1.5% from the previous quarter. Installments receivable totaled R$11.6 billion at the end of the period, with increases of 1.8% from June 2018 and of 5.8% from September 2017.

Loan Operations and Financial Guarantees Provided

A 3.5% decrease from the previous quarter, driven by the lower use of advances to deposit account holders. Compared to the first nine months of 2017, there was a 0.7% increase driven by a larger volume of credit origination in 2018.

In the chart below, we show the annualized ratio of revenues from loan operations to the loan portfolio and of revenues from guarantees provided to the financial guarantees provided portfolio.

¹ Includes units abroad ex-Latin America. (*) Loan portfolio and financial guarantees provided average balances for the previous two quarters.

Collection Services

Revenues from collection services decreased 2.3% compared to the previous quarter.

Compared to the first nine months of 2017, these revenues grew 11.4%, mainly driven by higher volume, pricing, increased offer and expansion of collection services due to the issuance and management of receivables in the mobile channel.

Advisory Services and Brokerage

Compared to the previous quarter, revenues from economic and financial advisory and brokerage services decreased R$139 million due to lower capital market activity.

Compared to the first nine months of 2017, these revenues increased 2.0%.

Fixed Income: we took part in local operations with debentures, promissory notes and securitization, which totaled R$25.1 billion up to September 2018, reaching the leadership position in the ANBIMA ranking.

Itaú Insurance, Pension Plan and Premium Bonds

Highlights

| · | Decrease in net income of Itaú Insurance, Pension Plan and Premium Bonds in this quarter was mainly driven by the gains from the liability adequacy test in pension plans in the second quarter of 2018, which did not repeat this quarter. Excluding this effect, the result from recurring activities would have been consistent with the previous quarter.

| · | Additionally, net contributions to pension plans decreased, and were offset by increase in earned premiums, especially the credit-related insurance portfolio.

As from the first quarter of 2018, we have disclosed the breakdown of Recurring Activities and Other Activities in Results from Itaú Insurance, Pension Plan and Premium Bonds. Major changes were the inclusion of IRB earnings in Recurring Activities and the reclassification of group life and credit life insurance portfolios distributed by brokers to Other Activities, since these portfolios are in run off.

(1) Includes variable compensation and stock option plans. (2) Does not include ISS, PIS and Cofins. (3) Does not consider overhead allocation.

The increase in non-interest expenses in the quarter is mainly driven by (i) higher personnel expenses associated to compensation, charges and benefits and to profit sharing, impacted by the effects of the collective bargaining labor agreement, and to the increase in the number of employees, and (ii) higher expenses in Latin America (ex-Brazil) impacted by the foreign exchange variation in the period.

Compared to the first nine months of 2017, the 6.4% increase was mostly driven by the integration of the retail operations acquired from Citibank. Additionally, personnel expenses were impacted by the increase in the number of employees and the collective labor agreement, partially offset by lower provisions for labor claims.

Administrative expenses increased 4.2% driven by higher marketing expenses for the World Soccer Cup and the launch of Pop Credicard. Compared to the same period of the previous year, expenses from Latin America (ex-Brazil) also increased, driven by the impact of the foreign exchange variation in the period and, in the second quarter of 2017, we had the refund of the fine paid to SBIF (Superintendencia de Bancos e Instituciones Financieras de Chile).

Expenses incurred in Brazil (ex-Citibank) increased 0.9% in the first nine months of 2018, below inflation for the period (4.5% - IPCA).

Efficiency Ratio

We present the efficiency ratio and the risk-adjusted efficiency ratio, which includes the cost of credit (result from loan losses, impairment and discounts granted).

Risk-Adjusted | = | Non-Interest Expenses (Personnel Expenses + Administrative Expenses + Operating Expenses + Other Expenses) + Cost of Credit
Efficiency Ratio | (Managerial Financial Margin + Commissions and Fees + Result of Insurance, Pension Plan and Premium Bonds + Tax Expenses for ISS, PIS, Cofins and Other Taxes)

Efficiency Ratio:

· 12-month period: increase of 240 basis points from the same period of the previous year. Non-interest expenses increased 6.4%, mainly driven by the integration of the retail operations acquired from Citibank. On the other hand, revenues increased only 0.7%, mainly as a result of the impact from the lower interbank deposit rate on our financial margin.

Risk-Adjusted Efficiency Ratio:

· 12-month period: decrease of 280 basis points from the same period of the previous year, driven by the 25.8% decrease in cost of credit as a result of lower provisions for loan losses and lower impairment charges on corporate securities.

Management Discussion & Analysis | Balance Sheet |

Balance Sheet by Currency

We have a foreign exchange risk management policy associated with our asset and liability positions, primarily intended to mitigate impacts from fluctuations in foreign exchange rates on consolidated results.

Brazilian tax legislation determines that gains and losses from exchange rate variation on permanent foreign investments must not be included in the tax basis. On the other hand, gains and losses arising from financial instruments used to hedge such asset positions are affected by tax effects. Therefore, in order not to expose net income to exchange rate variations, a liability position must be built at a higher volume than the hedged assets.

Management Discussion & Analysis | Risk and Capital Management |

Risk and Capital Management

We believe risk management is an essential tool to optimize the use of resources and select the best business opportunities to maximize value creation for shareholders. In this context, the risk appetite defines the nature and the level of risks acceptable and the risk culture guides the attitudes required to manage them.

With the aim of strengthening our values and aligning our employees' behavior with the guidelines established in risk management, we have adopted a number of initiatives to disseminate the risk culture. It strengthens the individual and collective responsibility of all employees in the management of the risks inherent to the performed activities, respecting our ethical way of doing business.

We take a prospective stance in relation to capital management and, through our Internal Capital Adequacy Assessment Process (ICAAP), we assess the adequacy of our capital to face the incurred risks, composed by credit, market, operational and other material risks. The result of the last ICAAP – dated as of December 2017 – showed that, in addition to having enough capital to face all material risks, we have a significant cushion, thus ensuring the soundness of our equity position.

Our risk management process includes:

| · | Identification and measurement of existing and potential risks in our operations.

| · | Alignment of institutional policies for risk management control, procedures and methodologies according to the guidelines of the Board of Directors and our corporate strategies.

| · | Management of our portfolio seeking optimal risk-return ratios.

Global Footprint

Latin America

Latin America is a priority for our international expansion due to geographic and cultural proximity to Brazil. Our purpose is to be recognized as the “Latin American Bank”, becoming a reference in the region for all financial services provided to individuals or companies.

Over the past years, we consolidated our presence in Argentina, Chile, Paraguay and Uruguay. In these countries, we operate in retail, companies, corporate and treasury segments, with commercial banking as our main focus. With the recent merger between Banco Itaú Chile and CorpBanca, which assured our presence in Colombia and Panama, we expanded even more our operations in the region. In Mexico, we are present through an office dedicated to equity research activities.

Itaú CorpBanca

In Chile, Colombia and Panama we operate through Itaú CorpBanca, from which results have been consolidated since the second quarter of 2016.

This operation represents an important step in our strategy to expand our presence in Latin America, diversifying our operations in the region.

Management Discussion & Analysis | Disclosure Criteria |

Disclosure Criteria

General

Managerial financial statements relating to prior periods may have been reclassified for comparison purposes.

The tables in this report show the figures in millions or billions. Variations and totals, however, are calculated in units. Therefore, there may be differences due to rounding.

Future expectations arising from the reading of this analysis should take into consideration the risks and uncertainties that involve any activities and that are outside the control of the companies of the conglomerate (political and economic changes, volatility in interest and foreign exchange rates, technological changes, inflation, financial disintermediation, competitive pressures on products, prices and changes in tax legislation, among others).

Managerial Financial Margin

Spread-Sensitive Operations: consists of the results from credit assets, non-credit interest-bearing assets and liabilities.

Financial Margin with the market: consists basically of treasury transactions that include Asset and Liability Management (ALM) and proprietary trading operations.

Coverage and Extended Coverage Ratio

Coverage ratio is calculated by dividing the total allowance balance by the balance of operations more than 90 days overdue. The extended coverage ratio is calculated by dividing the total allowance balance by the balance of operations more than 90 days overdue and renegotiated operations, excluding double counting of renegotiated operations more than 90 days overdue. Total allowance includes the allowance for financial guarantees provided, which totaled R$1,269 million in September 2018 and is recorded in liabilities in accordance with CMN Resolution No. 4,512/16.

Itaú Insurance, Pension Plan and Premium Bonds

The combined ratio is the sum of retained claims, selling expenses, administrative expenses, other operating income and expenses, tax expenses for ISS, PIS and Cofins and other taxes divided by earned premiums.

The extended combined ratio is the sum of these same expenses divided by the sum of earned premiums, managerial financial margin and commissions and fees.

VaR (Value at Risk)

The Consolidated VaR of Itaú Unibanco is calculated based on the Historical Simulation methodology, which fully reprices all its positions based on historical series of asset prices. In the third quarter of 2016, we started to calculate VaR of the regulatory portfolio based on internal models approved by the Brazilian Central Bank. Therefore, the breakdown of risk factors was standardized to comply with Circular No. 3,646 of the Brazilian Central Bank.

Business Analysis

Pro Forma Adjustments - Adjustments made to the balance sheet and income statement for the year are based on managerial information from the business units.

The financial statements were adjusted in order to replace the accounting stockholders’ equity with funding at market prices. Subsequently, the financial statements were adjusted to include revenues linked to allocated capital at each segment. The cost of subordinated debt and the respective remuneration at market prices were allocated to segments on a pro rata basis, in accordance with the economic allocated capital.

Impacts related to capital allocation are included in the Pro Forma financial statements. To this end, adjustments were made to the financial statements, using a proprietary model.

Allocated Capital - The economic allocated capital model (EAC) was adopted for the Pro Forma financial statements by segment and, as of 2015, we changed our calculation methodology. In addition to the Tier I allocated capital, the EAC model includes the effects of the calculated expected loan losses, complementary to that required by the Brazilian Central Bank through CMN Circular No. 2,682/99.

Accordingly, the allocated capital includes the following components: credit risk (including expected losses), operational risk, market risk, and insurance underwriting risk.

Based on Tier I capital measure we determined the Return on Allocated Capital, which corresponds to an operational performance ratio consistently adjusted to the required capital needed to support the risks of the financial positions assumed in accordance with our risk appetite.

As of the first quarter of 2016, we have adopted the Basel III rules in our managerial capital allocation model.

Income Tax Rate - We adopt the full income tax rate, net of the tax effect of payment of interest on capital, for the Retail Banking, Wholesale Banking and Activities with the Market + Corporation segments. The difference between the income tax amount determined for each segment and the effective income tax amount, as stated in the consolidated financial statements, is allocated in the column Activities with the Market + Corporation.

| 1 | Itaú Unibanco Highlights

1.1) Corporate Governance

Changes in the Executive Committee

As from January 2019 Caio Ibrahim David becomes the Wholesale General Director and Milton Maluhy Filho takes the position of Vice President of Risks and Finance, joining the Executive Committee

In September 2018 we announced some changes in our Executive Committee, as our Wholesale General Director Eduardo Vassimon has reached the limit age for exercising the duties of this position. Mr. Vassimon will be succeeded by Caio Ibrahim David, currently the Executive Vice President of the Risks and Finance Area, CFO and CRO, who is already a member of the Committee. Milton Maluhy Filho, who will end his term of office as CEO of Itaú Corpbanca in January, will take up the position from Mr. David. These changes were approved by the Nomination and Corporate Governance Committee and the Board of Directors.

1.2 Partnerships and Business

Minority interest in XP approved

Itaú Unibanco acquired 49.9% interest in capital, including 30.1% of total common shares

As disclosed in May 2017, Itaú Unibanco entered into an agreement to hold a minority interest in XP Investimentos, a company with a proven business model driven towards client experience. In accordance with this agreement, Itaú Unibanco will exert no influence in the commercial and operational policies of any company belonging to the group, nor will it have preference or exclusivity rights in the sale of its products. Accordingly, the management and running of XP business will remain fully independent, separated and self-ruling.

After approval from the Central Bank of Brazil, the financial settlement of this operation was carried out on August 31, 2018 by means of a capital contribution of R$600 million and the purchase of shares in the amount of R$5.7 billion1.

This agreement also provides for a single additional operation in 2022, subject to future approval from the Central Bank of Brazil. If approved, it will enable us to hold up to 62.4% of XP’s total capital stock (equivalent to 40.0% of common shares) based on a multiple (19 times) applied to XP’s earnings, and it is certain that the control of the XP group will remain unchanged, held by the shareholders of XP Controle Participações S.A.

¹ Amounts were adjusted from May 11, 2017 up to the financial settlement.

Employee Benefits Market - Programa de Alimentação ao Trabalhador (PAT)

This partnership will enable us to increase the offer of products to corporate clients

In September 2018, we entered into a partnership with Edenred Participações S.A., the parent company of Ticket Serviços S.A. in Brazil, to operate in the employee benefits market, which is mainly regulated by the Programa de Alimentação do Trabalhador - PAT. This partnership will enable us to extend the benefits provided by Ticket to clients in the wholesale, middlemarket, very small and small companies segments, the workers of which may take advantage of Ticket’s experience in the management and development of employee benefit solutions, besides having access to one of the broadest benefits acceptance networks.

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 50

Under this agreement, we will make a minority investment of 11% in Ticket, by means of a capital increase to be paid (i) in cash, equivalent to the book value of such equity interest, and (ii) with the contribution of distribution exclusivity rights regarding Ticket Restaurante, Ticket Alimentação, Ticket Cultura and Ticket Transporte to Itaú Unibanco’s corporate client base during the term of this partnership. Ticket will continue to distribute its products by means of other trade agreements and remain under Edenred’s control and management.

The completion of this transaction is conditioned on approvals from the Central Bank of Brazil and CADE, the Brazilian antitrust agency. We do not expect this agreement to have any material impact on our 2018 results.

POP Credicard

POS machines for self-employed individuals, micro entrepreneurs and small companies with short payment terms and lower fees

In July 2018, we announced the entry of the Credicard brand into the merchant acquiring segment, with a POS machine family used for payment with cards that will be offered for sale especially to self-employed individuals, micro entrepreneurs and small companies. The first machines launched are POP Credicard, a model with no printing coil, with chip and Wi-Fi capabilities, debit, credit, food and meal functions, and that is accepted by major brands, and Mega POP Credicard, which is similar to a traditional POS machine and features a printing coil to print proofs of payment, in addition to all the benefits above. With this initiative, we place ourselves among the best players of the sector, providing retailers with shorter payment terms and competitive fees.

Our choice of the Credicard brand was driven by its repositioning in the electronic payment means segment to keep up with technology and behavior changes in the world and meet the clients’ needs.

Interest held in Itaú CorpBanca

Under the Shareholders’ Agreement, we have increased our interest in the Chilean bank

In October 2018, we indirectly acquired 10.7 billion shares of Itaú CorpBanca for CLP65.7 billion, equivalent to approximately R$362.9¹ million, as a result of the Corp Group exercising a put option set forth in the shareholders’ agreement of Itaú CorpBanca. Accordingly, our interest in Itaú CorpBanca increased to 38.14%, from 36.06%, with no change in the governance of Itaú CorpBanca.

¹Based on the price of the financial settlement on October 17, 2018

No fees charged for Treasury Direct bonds, Pension funds and Fixed Income products

A novelty for all bank clients

In September 2018, we were able to show in practice what we have come here for: putting the client at the center of everything. Accordingly, we announced that we have straight away zeroed out our custody fees for Treasury Direct bonds offered by Itaú Corretora and for Fixed Income products (bank deposit certificates (CDB) from other managers, bills, debentures, real estate receivables certificates (CRI) and agribusiness receivables certificates (CRA)). Additionally, we also zeroed out the initial and final contribution fees for Private Pension plans¹ for all bank clients.

To access these no-fee products, Itaú Unibanco clients may access their account on the Internet or, if not an account holder, open an account via the Itaú Abreconta app. By following the route “Investimentos > Minha conta na Itaú Corretora”, clients will be able to register at our broker, a step required to trade treasury direct bonds. It is also important to complete the information requested so that clients get to know their investment profile and the options most fitting to meet their expectations.

This initiative provides our clients with more investment options in a scenario of low interest rates.

PayPal

A digital payment platform

In August 2018, we announced a partnership in the digital segment between Itaú Unibanco, Rede and PayPal, as an alternative to ensure that our clients have more convenience when shopping online and to increase sales for retailers, providing more agility and security. The purpose is to create exclusive value proposals by combining expertise to speed up digital inclusion, boost the volume of global digital trade and further cooperate to mitigate risks for clients.

PayPal offers an open digital payment platform to its users, with 244 million active accounts, available in over 200 markets throughout the world.

1.4 Sustainability

Dow Jones Sustainability Index (DJSI)

We are the only Latin-American bank to make up the index since it was created in 1999

We were selected for the 19th consecutive year to make up the Dow Jones Sustainability Index (DJSI), the main sustainability index in the world, in its 2018/2019 edition. In this new edition, we achieved the best rate in the banking sector according to the “Environment Reporting”, “Fiscal Strategy”, “Financial Stability and Systemic Risk”, “Financial Inclusion”, “Corporate Citizenship and Philanthropy”, and “Social Reporting” criteria. Additionally, we were also selected to make up the Dow Jones Sustainability Emerging Markets Index.

Since its creation in January 1999, the DJSI has become an important benchmark for asset management institutions that make investments based on ESG (Environment, Social, and Governance) metrics, which, as a result, include shares of DJSI companies in its portfolio.

Diversity Week

Commitments and initiatives to promote LGBT+ Rights are an important step to protect people’s rights

In the first week of August, we held the LGBT+ Itaú Unibanco Diversity Week, when topics such as sexual orientation, gender identity, and the significance of diversity in the workplace were addressed. This event was attended by a number of outstanding guests championing the LGBT cause, inside and outside the bank, and was concluded with the signing of the letter of commitment to the Forum on Companies and LGBT Rights. Therefore, we took another major step to reinforce the commitment to respecting and valuing the rights of lesbian, gay, bisexual, transvestite, and transgender persons, by engaging their value chain and raising awareness in society.

1.5) Regulatory Environment

Banking regulation is essential for the soundness and efficiency of the financial system. When amended, it may have direct impact on the bank’s results. We highlight below the main change in this quarter:

General Personal Data Protection Act

In August 2018, Law No. 13,709 was enacted, providing for personal data protection and aimed at protecting the fundamental rights to freedom, privacy and personality. A regulatory framework of paramount importance to society, this law will come into force in February 2020. This topic has always been a priority for Itaú Unibanco, as shown in our Corporate Policy on Information Security and Cyber Security, available on our IR website www.itau.com.br/investor-relations > Itaú Unibanco > Corporate Governance > Rules and Policies.

(3) We monitor the Liquidity Coverage Ratio (LCR), as it refers to free and highly liquid assets and net cash outflows over a 30-day period and is calculated based on the methodology defined by Circular No. 3,749, of the Central Bank of Brazil, in line with international guidelines.

From January to September 2018, net income was R$18.8 billion, up 3.5% from the same period of the previous year. Gross income related to financial operations was adversely impacted by the tax effect of our foreign investments hedge, which was offset in the tax lines of our statement of income. This income was also negatively impacted by the cycle of reductions in the Selic rate started in October 2016, which was offset by lower provisions for loan losses.

Our personnel, administrative and operating expenses increased 9.4% between the first nine months of 2017 and 2018, mainly driven by an increase in compensation and benefits and in credit card selling expenses. Our risk-adjusted efficiency ratio was 61.0%, down 270 basis points from the same period of 2017.

Itaú Unibanco is present in 19 countries with a team totaling 100.8 thousand employees on September 30, 2018, whose work is customer-satisfaction oriented accordingly. Employees’ fixed compensation plus charges and benefits totaled R$12.6 billion in the first nine months of 2018.

In this nine-month period, we highlight the 7.7% increase in commissions and fees from the same period of 2017, mainly those related to fund management, service packages, and credit cards.

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 55

Loan portfolio reached R$600.1 billion at the end of September 2018, up 11.3% from the same period in 2017. From January to September of 2018, we recorded an increase in the portfolios for individuals and very small, small and middle-market companies.

We highlight below our loan portfolio with financial guarantees provided at the end of September 2018:

The strategic credit risk management supports the quality of our loan portfolio, and nonperforming loans over 90 days overdue closed the third quarter of 2018 at 2.9%, down 30 basis points from the same period of the previous year.

3.1) Capital Management

Aimed at ensuring soundness and capital availability to support our business growth, regulatory capital levels were kept above those required by the Central Bank of Brazil, as evidenced by the Common Equity Tier I, Tier I, and BIS ratios, which reached, in the third quarter of 2018, 13.9%, 14.9% and 16.9%, respectively. These indicators provide evidence of our capacity of absorbing unexpected losses.

Furthermore, we intend to maintain the minimum level, established by the Board of Directors, of 13.5% for Tier 1¹ Capital fully loaded, which must be composed of at least 12% Common Equity Tier I. The percentage of dividends and interest on capital to be distributed to stockholders is directly related to the full Tier 1 Capital fully loaded established by the Board of Directors. This amount is determined based on profitability in the year, the prospective use of capital based on the expected business growth, share buyback programs, mergers and acquisitions and regulatory changes that may modify capital requirements, and changes in tax legislation. Therefore, the percentage to be distributed may change every year based on the company’s profitability and capital demands, and always takes into account the minimum distribution set forth in the Bylaws.

¹ Considers the Basel III requirements, and the ratio of September 2018 was 14.8%.

Note 2 – Presentation and consolidation of the financial statements

| a) | Presentation

The financial statements of ITAÚ UNIBANCO HOLDING and of its subsidiaries (ITAÚ UNIBANCO HOLDING CONSOLIDATED) have been prepared in accordance with the accounting principles established by the Brazilian Corporate Law, including the amendments introduced by Laws nº. 11,638, of December 28, 2007, and nº. 11,941, of May 27, 2009 and in conformity, when applicable, with instructions issued by the National Monetary Council (CMN), Central Bank of Brazil (BACEN), the Brazilian Securities and Exchange Commission (CVM), the National Council of Private Insurance (CNSP), the Superintendence of Private Insurance (SUSEP) and the National Superintendence of Supplementary Pension – (PREVIC),which include the use of estimates deemed necessary to calculate the accounting provisions and the valuation of financial assets. Information in the financial statements and respective notes evidence all relevant information inherent in the financial statements, and only them, which are consistent with information used by management in its administration.

As set forth in the sole paragraph of article 7 of BACEN Circular nº. 3,068, of November 8, 2001, securities classified as trading securities (Note 4c) are presented in the Consolidated Balance Sheet under Current Assets, regardless of their maturity dates.

Lease Operations are presented at present value in the Consolidated Balance Sheet, being that the related income and expenses, which represent the financial results of these operations, are presented, grouped together, under Loan, Lease and Other Credit Operations in the Statement of Income. Advances on exchange contracts are reclassified from Other Liabilities – Foreign exchange portfolio to Loan operations. The foreign exchange result is presented on an adjusted basis, with reclassification of expenses and income, in order exclusively to represent the impact of variations and differences in rates on the balance sheet accounts denominated in foreign currencies.

| b) | Consolidation

As set forth in paragraph 1, article 2, of BACEN Circular nº. 2,804, of February 11, 1998, the financial statements of ITAÚ UNIBANCO HOLDING CONSOLIDATED include the consolidation of its foreign branches and subsidiaries.

Intercompany transactions, intercompany balances and intercompany results have been eliminated on consolidation. The investment funds of which ITAÚ UNIBANCO HOLDING CONSOLIDATED companies are the main beneficiaries or holders of principal obligations are consolidated. The investments in these fund portfolios are classified by type of transaction and were distributed by type of security, based on the same categories to which these securities were originally allocated. The effects of foreign exchange variations on investments abroad are classified under the heading Securities and derivative financial instruments in the Statement of Income for subsidiaries with the same functional currency as the parent company, and in Asset valuation adjustment for subsidiaries with a functional currency different from that of the parent company (Note 4t).

The difference in Net Income and Stockholders’ Equity between ITAÚ UNIBANCO HOLDING and ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 15d) results from the adoption of different criteria for the amortization of goodwill originating from purchases of investments, from the recording of transactions with minority stockholders where there is no change of control (Note 4r), and in the record of exchange variations on investments abroad, and hedges of these investments where the functional currency is different from that of the parent company, net of the respective deferred tax assets.

In ITAÚ UNIBANCO HOLDING, the goodwill recorded in subsidiaries, mainly acquisition by minority stockholders of REDE, is amortized based on the expected future profitability and appraisal reports, or upon realization of the investment, according to the rules and guidance of CMN and BACEN.

In ITAÚ UNIBANCO HOLDING CONSOLIDATED, from January 1st, 2010, the goodwill originating from the purchase of investments is no longer fully amortized as part of the consolidated financial statements (Note 4j). By December 31, 2009, the goodwill generated had been fully amortized in the periods in which investments were made.

Note 3 – Requirements regarding capital and fixed asset limits

ITAÚ UNIBANCO HOLDING CONSOLIDATED is subject to the requirements of the Central Bank of Brazil (BACEN), which determines minimum capital requirements, procedures to assess information on globally systemic important banks (G-SIB), fixed asset limits, loan limits, accounting practices and compulsory deposit requirements, thereby requiring banks to conform to the regulation based on the Basel Accord for capital adequacy purposes. Additionally, both the National Council of Private Insurance (CNSP) and the Superintendence of Private Insurance (SUSEP) issue regulations on capital requirements that impact our insurance operations, and private pension and capitalization plans.

Further details on the Capital Management of ITAÚ UNIBANCO HOLDING CONSOLIDATED, which are not an integral part of the financial statements, can be found on the website www.itau.com.br/investor-relations section “Reports” / Pillar 3 and Global Systemically Important Banks.

| a) | Capital Requirements in Place and in Progress

ITAÚ UNIBANCO HOLDING CONSOLIDATED’s minimum capital requirements comply with the set of BACEN resolutions and circulars, which established in Brazil the global capital requirement standards known as Basel III. They are expressed as ratios obtained from the ratio between available capital - represented by Referential Equity (PR), or Total Capital, composed of Tier I Capital (which comprises Common Equity and Additional Tier I Capital) and Tier II Capital, and the Risk-Weighted Assets (RWA).

For purposes of calculating these minimum capital requirements, the total RWA is determined as the sum of the risk weighted asset amounts for credit, market, and operational risks. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses the standardized approaches to calculate credit and operational risk-weighted asset amounts.

As from September 1, 2016, BACEN authorized ITAÚ UNIBANCO HOLDING CONSOLIDATED to use market risk internal models to determine the total amount of regulatory capital (RWAMINT), replacing the RWAMPAD portion, as set forth in BACEN Circular nº 3,646.

From January 1, 2018 to December 31, 2018, the minimum capital ratio required is 8.625%, and, following the gradual decrease schedule, it will be 8% on January 1, 2019.

The table below shows Basel III implementation calendar for Brazil, as defined by BACEN, in which the figures refer to the percentage of ITAÚ UNIBANCO HOLDING CONSOLIDATED risk-weighted assets.

According to CMN Resolution nº. 4,193, as amended, minimum capital requirements are calculated by the RWA amount, which is obtained by adding the terms listed below:

RWA = RWACPAD + RWAMINT + RWAOPAD

RWACPAD = portion related to exposures to credit risk, calculated using the standardized approach;

RWAMINT = portion related to capital required for market risk, composed of the maximum between the internal model and 80% of the standardized model, regulated by BACEN Circulars 3,646 and 3,674;

RWAOPAD = portion related to capital required for operational risk, calculated based on the standardized approach.

Operations subject to foreign exchange variation are accounted for at the corresponding amount in local currency. Liabilities are presented net of the transaction costs incurred, when relevant, calculated pro rate die.

| c) | Securities - Recorded at the cost of acquisition restated by the index and/or effective interest rate and presented in the Balance Sheet, according to BACEN Circular nº. 3,068, of November 8, 2001. Securities are classified into the following categories:

| · | Trading securities – Securities acquired to be actively and frequently traded, and adjusted to market value, with a counter-entry to the results for the period;

| · | Available-for-sale securities – Securities that can be negotiated but are not acquired for the purposes of active and frequent trading. They are adjusted to their market value, with a counter-entry to an account disclosed in stockholders’ equity;

| · | Held-to-maturity securities – Securities, except for non-redeemable shares, which the bank has the financial condition and intend, or is required to hold in the portfolio to maturity, are recorded at the cost of acquisition, or market value, whenever these are transferred from another category. The securities are adjusted using the accrual method through maturity, and are not adjusted to market value.

Gains and losses on available-for-sale securities, when realized, are recognized on the trade date in the statement of income, with a counter-entry to a specific stockholders’ equity account.

Decreases in the market value of available-for-sale and held-to-maturity securities below their related costs, resulting from non-temporary causes, are recorded in the results as realized losses.

| d) | Derivative financial instruments - These are classified on the date of their acquisition, according to whether or not management intends to use them either as a hedge, according to BACEN Circular nº. 3,082, of January 30, 2002.

The derivatives that are used for protection against risk exposure or to modify the characteristics of financial assets and liabilities, which have changes in market value closely related with those of the items being protected at the beginning and throughout the duration of the contract, and which are found to be effective reducing the risk related to the exposure being protected against, are classified as hedges, in accordance with their nature:

| · | Market Risk Hedge – Financial assets and liabilities, as well as their related financial instruments, are accounted for at their market value, plus realized and unrealized gains and losses, which are recorded directly in the statement of income;

| · | Cash Flow Hedge - The effective amounts of the hedge of financial assets and liabilities, as well as their related financial instruments, are accounted for at their market value plus realized and unrealized gains and losses, net of tax effects, when applicable, and recorded in a specific account in stockholders’ equity. The ineffective portion is recorded directly in the statement of income;

The ineffective portion is recognized in income for the period.

| e) | Loan, lease and other credit operations (operations with credit granting characteristics) – These transactions are recorded at present value and calculated pro rata die based on the variation of the contracted index and interest rate, and are recorded on basis until the 60th day overdue in financial companies, according to the estimates of receipt. After the 60th day, income is recognized upon the effective receipt of installments. Credit card operations include receivables arising from the purchases made by cardholders. Funds corresponding to these amounts to be paid to the accrediting organization are in liabilities, in the heading Interbank Accounts – Receipts and Payments Pending Settlement.

| f) | Allowance for loan losses - The balance of the allowance for loan losses was recorded based on a credit risk analysis, at an amount considered sufficient to cover loan losses in accordance with the rules determined by CMN Resolution nº. 2,682 of December 21, 1999, which are as follows are:

| · | Provisions are recorded from the date on which loans are granted, based on the client’s risk rating and on the periodic quality evaluation of clients and industries, and not only in the event of default;

| I - | Contingent assets and liabilities

Refer to potential rights and obligations arising from past events for which materialization depends on uncertain future events:

| · | Contingent assets - Not recognized, except where there is evidence of a high likelihood level of realization, usually represented by claims awarded a final and unappealable judgment and confirmation of the recoverability of the claim through receipt of amounts or through offsetting against another liability;

| · | Contingent liabilities - Basically arise from administrative proceedings and lawsuits inherent in the normal course of business filed by third parties, former employees and governmental bodies, in connection with civil, labor, tax and social security lawsuits and other risks. These contingencies are calculated on a conservative basis, usually recorded based on the opinion of legal advisors and considering the probability that financial resources shall be required to settle the obligation, the amount of which may be estimated with sufficient certainty. Contingencies are classified either as probable, for which provisions are recognized; possible, which are disclosed but not recognized; and remote, for which recognition or disclosure are not required. Any contingent amounts are measured through the use of models and criteria which allow adequate measurement, in spite of the uncertainty of their terms and amounts.

Pension plans - defined benefit plans

The liability (or asset, as the case may be) recognized in the consolidated balance sheet with respect to the defined benefit plan corresponds to the present value of the defined benefit obligations on the balance sheet date less the fair value of the plan assets. The defined benefit obligation is annually calculated by an independent actuarial consulting company using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated amount of future cash flows of benefit payments based on the Brazilian treasury long term securities denominated in Reais and with maturity periods similar to the term of the pension plan liabilities.

The following amounts are recognized in the Consolidated statement of income:

| · | current service cost is defined as the increase in the present value of obligations resulting from employee service in the current period;

| · | interest on the net amount of assets (liabilities) of defined benefit plans is the change, during the period, in the net amount recognized in assets and liabilities, due to the time elapsed, which comprises the interest income on plan assets, interest expense on the obligations of the defined benefit plan and interest on the asset ceiling effects.

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 85

Actuarial gains and losses arise from the non-realization of the actuarial assumptions established in the latest actuarial evaluation as compared to those effectively carried out, as well as the effects of changes in these assumptions. Gains and losses are fully recognized in Equity Valuation adjustments.

Pension plans - defined contribution

For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING CONSOLIDATED, through pension plan funds, are recognized as expenses when due.

Other post-employment benefit obligations

Certain companies that merged into ITAÚ UNIBANCO HOLDING CONSOLIDATED over the past few years were sponsors of post-employment healthcare benefit plans. ITAÚ UNIBANCO HOLDING CONSOLIDATED is contractually committed to maintaining these benefits over specific periods, as well as the benefits granted based on judicial rulings.

Similarly to the defined benefit pension plans, these obligations are assessed annually by independent and qualified actuaries, and the costs expected from these benefits are accrued during the length of service. Gains and losses arising from adjustments and changes in actuarial assumptions are debited from or credited to stockholders’ equity in Equity asset valuation adjustment in the period in which they occur.

| t) | Foreign currency translation

| I- | Functional and presentation currency

The Consolidated financial statements of ITAÚ UNIBANCO HOLDING CONSOLIDATED are presented in Reais, which is its functional and presentation currency. For each subsidiary and investment in associates and joint ventures, ITAÚ UNIBANCO HOLDING CONSOLIDATED defined the functional currency, as provided for in CMN Resolution Nº 4,524, of September 29, 2016.

The assets and liabilities of subsidiaries are translated as follows:

| · | Assets and liabilities are translated at the closing rate at the balance sheet date;

| · | Income and expenses are translated at monthly average exchange rates.

Equity in the earnings of subsidiaries abroad is recognized as follows:

| · | For those with functional currency equal to Real: Income for the period;

| · | For those with functional currency different to Real:

| a) | Income for the period; Portion related to the subsidiary’s effective income; and

| b) | Stockholders’ equity: Portion related to foreign exchange adjustments arising from the translation process, net of tax effects.

| II - | Foreign Currency Transactions

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the consolidated statement of income as part of securities and derivative financial instruments.

For subsidiaries abroad, any operations carried out in a currency other than their respective functional currencies will be translated at the foreign currency rates of the respective trial balance or balance sheet of ITAÚ UNIBANCO HOLDING CONSOLIDATED for monetary items, assets and liabilities recognized at fair or market value and for items not classified as monetary, provided that the subsidiary’s functional currency is equal to the Real. For other cases, operations are translated at the foreign exchange rate at the transaction date.

| f) | Derivative financial instruments

The globalization of the markets in recent years has resulted in a high level of sophistication of financial products used. As a result of this process, there has been increasing demand for derivative financial instruments to manage market risks, mainly arising from fluctuations in interest and exchange rates, commodities and other asset prices. Accordingly, ITAÚ UNIBANCO HOLDING CONSOLIDATED operate in the derivatives markets for meeting the growing needs of their clients, as well as enacting their risk management policy. This policy is based on the use of derivative instruments to minimize the risks resulting from commercial and financial operations.

The derivative financial instrument business with clients is carried out after the approval of credit limits. The process of limit approval takes into consideration potential stress scenarios.

Knowing the client, the sector in which it operates and its risk appetite profile, in addition to providing information on the risks involved in the transaction and the negotiated conditions, ensures transparency in the relationship between the parties and the supply of a product that better meets the needs of the client.

The derivative transactions carried out by ITAÚ UNIBANCO HOLDING CONSOLIDATED with clients are neutralized in order to eliminate market risks.

The derivative contracts traded by the institution with clients in Brazil include swaps, forwards, options and futures contracts, which are registered at the B3. Overseas transactions are carried out with futures, forwards (onshore), options and swaps mostly listed on the Chicago, New York and London Exchanges. It should be emphasized that there are over-the-counter operations, but their risks are low compared to the institutions’ total. Noteworthy is also the fact that there are no structured operations based on subprime assets and all operations are based on risk factors traded on stock exchanges.

The main risk factors of the derivatives, assumed at 09/30/2018, were related to the foreign exchange rate, interest rate, commodities, US Dollar coupon, Reference Rate coupon, LIBOR and variable income. The management of these and other market risk factors is supported by sophisticated statistical and deterministic models. Based on this management model, the institution, through the use of transactions involving derivatives, has been able to optimize the risk-return ratios, even in highly volatile situations.

Most derivatives included in the institution’s portfolio are traded on stock exchanges. The prices disclosed by stock exchanges are used for these derivatives, except in cases in which the low representativeness of price due to the liquidity of a specific contract is identified. Derivatives typically valued in this way are futures contracts. Likewise, there are other instruments whose quotations (fair prices) are directly disclosed by independent institutions and which are valued based on this direct information. A substantial portion of the Brazilian government securities, highly-liquid international (public and private) securities and shares are in this situation.

For derivatives the prices of which are not directly disclosed by stock exchanges, fair prices are obtained based on pricing models which use market information, deducted based on the prices disclosed for higher liquidity assets. Interest and market volatility curves which provide input for the models are extracted from those prices. Over- the-counter derivatives, forward contracts and securities with limited liquidity are in this situation.

The total value of margins pledged in guarantee was R$ 7,846,393 (R$ 9,013,115 at 09/30/2017) and was basically composed of government securities.

| g) | Sensitivity analysis (trading and banking portfolios)

In compliance with CVM Instruction nº. 475, ITAÚ UNIBANCO HOLDING CONSOLIDATED carried out a sensitivity analysis by market risk factors considered relevant. The biggest losses arising, by risk factor, in each scenario, were stated together with their impact on the results, net of tax effects, by providing an overview of ITAÚ UNIBANCO HOLDING CONSOLIDATED’s exposure under exceptional scenarios.

The sensitivity analyses of the banking and the trading portfolio shown in this report are an evaluation of a static position of the portfolio exposure and, therefore, do not consider management’s quick response capacity (treasury and control areas), which triggers risk mitigating measures, whenever a situation of high loss or risk is identified by minimizing the sensitivity to significant losses. In addition, the study's sole purpose is to disclose the exposure to risk and the respective protective actions, taking into account the fair value of financial instruments, irrespective of the accounting practices adopted by ITAÚ UNIBANCO HOLDING CONSOLIDATED.

Note 11 – Contingent assets and liabilities and legal liabilities – tax and social security

ITAÚ UNIBANCO HOLDING, as a result of the ordinary course of its business, may be a party to legal lawsuits of labor, civil and tax nature. The contingencies related to these lawsuits are classified as follows:

a) Contingent Assets: There are no contingent assets recorded.

b) Provisions and contingencies: The criteria to quantify contingencies are adequate in relation to the specific characteristics of civil, labor and tax lawsuits portfolios, as well as other risks, taking into consideration the opinion of its legal advisors, the nature of the lawsuits, the similarity with previous lawsuits and the prevailing previous court decisions.

| - | Civil lawsuits:

In general, contingencies arise from claims related to the revision of contracts and compensation for damages and pain and suffering and the lawsuits are classified as follows:

Collective lawsuits: Related to claims of a similar nature and with individual amounts that are not considered significant. Contingencies are determined on a monthly basis and the expected amount of losses is accrued according to statistical references that take into account the nature of the lawsuit and the characteristics of the court (Small Claims Court or Regular Court). Contingencies and provisions are adjusted to reflect the amounts deposited as guarantee for their execution when realized.

Individual lawsuits: Related to claims with unusual characteristics or involving significant amounts. These are periodically calculated based on the calculation of the amount claimed. Probability of loss, which is estimated based on the characteristics of the lawsuit. The amounts considered as probable losses are recorded as provisions.

It should be mentioned that ITAÚ UNIBANCO HOLDING is a party to specific lawsuits related to the collection of understated inflation adjustments to savings accounts resulting from economic plans implemented in the 80’s and 90’sn. as a measure to combat inflation.

Although ITAÚ UNIBANCO HOLDING complied with the rules in effect at the time, the company is a defendant in lawsuits filed by individuals that address this topic, as well as in class actions filed by: (i) consumer protection associations; and (ii) the Public Prosecution Office on behalf of savings account holders. With respect to these lawsuits, ITAÚ UNIBANCO HOLDING records provisions when it is served and when the individuals apply to enforce the decision rendered by the Judicial Branch, using the same criteria adopted to determine provisions for individual lawsuits.

The Federal Supreme Court (STF) has issued some decisions favorable to savings account holders, but it has not established its understanding with respect to the constitutionality of the economic plans and their applicability to savings accounts. Currently, the appeals involving these matters are suspended, as determined by the STF, until it pronounces a final decision.

In December 2017, through mediation of the Federal Attorney’s Office (AGU) and of supervision of the Central Bank of Brazil (BCB), savers (represented by two civil associations, FEBRAPO and IDEC) and FEBRABAN entered into an instrument of agreement aiming at resolving lawsuits related to economic plans, and ITAÚ UNIBANCO HOLDING has already adhered to its terms. Said agreement was approved on March 1, 2018, by the Plenary Session of the Federal Supreme Court (STF) and, savers may adhere to their terms for a 24-month period, counted as from May 22, 2018 with the subsequent conclusion of lawsuits.

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 118

No amount is recorded as a provision in relation to Civil lawsuits which likelihood of loss is considered possible, which total estimated risk is R$ 3,818,028 (R$ 3,615,964 at 09/30/2017), in this amount there are no values resulting from interests in joint ventures.

| - | Labor claims

Contingencies arise from lawsuits in which labor rights provided for in labor legislation specific to the related profession are discussed, such as: overtime, salary equalization, reinstatement, transfer allowance, pension plan supplement, among others, are discussed. These lawsuits are classified as follows:

Collective lawsuits: related to claims considered similar and with individual amounts that are not considered relevant. The expected amount of loss is determined and accrued on a monthly basis in accordance with a statistical share pricing model and is reassessed taking into account the court rulings. These contingencies are adjusted to the amounts deposited as guarantee for their execution when realized.

Individual lawsuits: related to claims with unusual characteristics or involving significant amounts. These are periodically calculated based on the calculation of the amount claimed. Probability of loss which, in turn, is estimated in accordance with the actual and legal characteristics related to that lawsuit.

No amount is recorded as a provision for labor claims for which the likelihood of loss is considered possible, and for which the total estimated risk is R$ 155,934 (R$ 56,808 at 09/30/2017).

| - | Other Risks

These are quantified and accrued mainly based on the evaluation of rural credit transactions with joint liability and FCVS (salary variations compensation fund) credits assigned to Banco Nacional.

| d) | Assets pledged as contingencies

Assets pledged as collateral for contingencies refer to lawsuits involving contingent liabilities and are restricted or in escrow deposits, as shown in the table below:

Securities (basically financial treasury bills – Note 6b) |  |  | 748,481 |  |  |  | 951,620 |
Deposits in guarantee |  |  | 4,581,009 |  |  |  | 4,623,428 |

ITAÚ UNIBANCO HOLDING’s litigation provisions are long-term, considering the time required to conclude legal cases through the court system in Brazil, which prevents the disclosure of a deadline for their conclusion.

The legal advisors believe that ITAÚ UNIBANCO HOLDING is not a party to this or any other administrative proceedings or lawsuits that could significantly affect the results of its operations.

(*) The average funding rate, net of tax effects, was used to determine the present value.

The projections of future taxable income include estimates related to macroeconomic variables, exchange rates, interest rates, volume of financial operations and service fees and others, which can vary in relation to actual data and amounts.

Net income in the financial statements is not directly related to the taxable income for income tax and social contribution, due to differences between the accounting criteria and tax legislation, in addition to corporate aspects. Accordingly, we recommend that the trends for the realization of deferred tax assets arising from temporary differences, income tax and social contribution loss carry forwards are not used as an indication of future net income.

| IV- | Considering the temporary effects introduced by Law nº. 13,169/15, which increased the social contribution rate to 20% through December 31, 2018, tax credits were recognized based on their likelihood of realization. As at 09/30/2018 and 09/30/2017, there are no unrecognized tax credits.

| g) | Share-based payment

ITAÚ UNIBANCO HOLDING and its subsidiaries have share-based payment programs aimed at involving its management members and employees in the medium and long term corporate development process.

These payments are only made in years where there are sufficient profits to enable the distribution of mandatory dividends, in order to limit the maximum dilutive effect to which stockholders are subject, and at a quantity that does not exceed the limit of 0.5% of the total shares held by the controlling and minority stockholders at the balance sheet date.

These programs are settled through the delivery of ITUB4 treasury shares to stockholders.

From 01/01 to 09/30/2018, the accounting effect of the Share-based payment in income was R$ (460,366) (R$ (381,343) from 01/01 to 09/30/2017).

| I – | Stock Option Plan (Simple Options)

ITAÚ UNIBANCO HOLDING has a Stock Option Plan (“Simple Options”) aimed at involving management members and employees in the medium and long term corporate development program of ITAÚ UNIBANCO HOLDING and its subsidiaries, offering them the opportunity to benefit from the appreciation that their work and dedication bring to the shares.

In addition to the awards provided under the Plan, ITAÚ UNIBANCO HOLDING also maintains control over the rights and obligations in connection with the options granted under the plans approved at the Extraordinary Stockholders’ Meetings held on April 24, 2009 and April 19, 2013 related to the Unibanco – União de Bancos Brasileiros S.A., Unibanco Holdings S.A. and Redecard S.A. stock option plans, respectively. Accordingly, the exchange of shares for ITUB4 did not have a relevant financial impact.

Simple options have the following characteristics:

| a) | Exercise price: calculated based on the average prices of shares in the three months of the year prior to the grant date. The prices determined will be inflation-adjusted to the last business day of the month prior to the option exercise date based on IGP-M or, in its absence, on an index to be determined internally, and should be paid within the period in force for the settlement of operations on B3.

| b) | Vesting period: determined upon issue, from one to seven years, counted from the grant date. The vesting period is normally determined at five years.

| c) | Fair value and economic assumptions for cost recognition: the fair value of Simple Options is calculated on the grant date based on the Binominal model. Economic assumptions used are as follows:

| (i) | Exercise price: exercise price previously agreed upon the option issue, adjusted by the IGP-M variation;

| (ii) | Price of the underlying asset (ITUB4 shares): closing price on B3 on the calculation base date;

| (iii) | Expected dividends: the average annual return rate for the last three years of dividends paid plus interest on capital of the ITUB4 share;

| (iv) | Risk-free interest rate: IGP-M coupon rate at the expiration date of the Simple Option;

| (v) | Expected volatility: calculated based on the standard deviation from the history of the last 84 monthly returns of the ITUB4 share closing prices, disclosed by B3, adjusted by the IGP-M variation.

| ll – | Partner Plan

The employees and management members of ITAÚ UNIBANCO HOLDING and its subsidiaries may be selected to participate in the program investing a percentage of their bonus to acquire ITUB4 shares and share-based instruments. Accordingly, the ownership of these shares should be held by the beneficiaries for a period from three to five years, counted from the initial investment, and are thus subject to market price variation. After complying with the suspensive conditions set forth in the program, beneficiaries will be entitled to receive ITUB4 as consideration, in accordance with the numbers of shares provided for in the program regulation.

The acquisition prices of own shares and Share-Based Instruments are established every six months and are equivalent to the average of the ITUB4 quotation in the 30 days prior to the determination of the acquisition price.

The fair value of the ITUB4 as consideration is the market price at the grant date, less expected dividends.

The weighted average of the fair value of the ITUB4 shares as consideration was estimated at R$ 39.33 per share at 09/30/2018 (R$ 32.33 per share at 09/30/2017).

Law nº. 12,973/14, which adjusted the tax legislation to the international accounting standards and terminated the Transitional Tax Regime (RTT), set up a new legal framework for payments made in shares. We made changes to the Partner Plan, and adjusted its tax effects, with conform with this new legislation.

| III- | Variable Compensation

The policy established in compliance with CMN Resolution nº. 3,921/10 sets forth that fifty percent (50%) of the management’s variable compensation should be paid in cash and fifty percent (50%) should be paid in shares for a period of three years. Shares are delivered on a deferred basis, of which one-third (1/3) per year, will be contingent upon the executive’s remaining with the institution. The deferred unpaid portions may be reversed proportionally to the significant reduction of the recurring income realized or the negative income for the period.

The fair value of the ITUB4 share is the market price at its grant date.

The weighted average of the fair value of ITUB4 shares was estimated at R$ 51.07 per share at 09/30/2018 (R$ 38.23 per share at 09/30/2017).

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 152

To obtain the market values for these financial instruments, the following criteria were adopted:

| · | Interbank investments were determined based on their nominal amounts, monetarily restated as at their maturity dates and discounted to present value using future market interest rates and swap market rates for fixed-rate securities and using market interest rates for fixed-rate securities, achieved up to the closing of B3 at the balance sheet date, for floating-rate securities;

| · | Securities and derivative financial instruments, according to the rules established by Circulars nº. 3,068 and 3,082 of November 8, 2001 and January 30, 2002, respectively, issued by BACEN, are recorded at their market values, except for those classified as Held to Maturity. Government securities allocated in this category have their market value calculated based on the rates obtained in the market, and validated through the comparison with information provided by the National Association of Financial Market Institutions (ANBIMA). Private securities included in this category have their market value calculated using a criterion similar to the one adopted for Investments in Interbank Deposits, as described above;

| · | Loans with maturities over 90 days, when available, were calculated based on the net present value of future cash flows discounted at market interest rates effective on the balance sheet date;

| · | Investments - in companies B3 and Porto Seguro at the share value quoted on stock exchanges.

| · | Time and interbank deposits and funds from the acceptance and issuance of securities and foreign borrowing through securities, when available, were calculated based on their present value determined by future cash flows discounted at market rates obtained at the closing of B3 on the balance sheet date;

| · | Subordinated debt, based on the net present value of future fixed or floating cash flows in foreign currency, net of the market interest rates effective on the balance sheet date and considering the credit risk of the issuer. The floating cash flows are estimated from the interest curves of the indexation market places;

| · | Treasury shares are valued according to the average quotation available on the last trading day of the month or, if this is not available, according to the most recent quotation on prior trading days, published in the daily bulletin of each Stock Exchange.

| a) | Retirement plans

ITAÚ UNIBANCO HOLDING CONSOLIDATED and certain subsidiaries sponsor defined benefit and variable contribution plans, whose basic purpose is to grant benefits that, in general, provide a life annuity benefit, and may be converted into survivorship annuities, according to the plan's regulations. They also sponsor defined contribution plans, the benefit of which is calculated based on the accumulated balance at the eligibility date, according to the plan's regulations, which does not require actuarial calculation, except as described in Note 18c.

Employees hired prior to July 31, 2002, for those who came from Itaú, and prior to February 27, 2009 for those who came from Unibanco, are beneficiaries of the above-mentioned plans. As regards the employees hired after these dates, they have the option to voluntarily participate in a variable contribution plan (PGBL), managed by Itaú Vida e Previdência S.A.

Supplementary plans are managed by closed-end private pension entities with independent legal structures, as detailed below:

| b) | Governance

The closed-end private pension entities (EFPC) and benefit plans they manage are regulated in conformity with the related specific legislation. The EFPC are managed by the Executive Board, Advisory Council and Fiscal Council, with some members appointed by the sponsors and others appointed as representatives of active and other participants, pursuant to the respective Entity’s bylaws. The main purpose of the EFPC is to pay benefits to eligible participants, pursuant to the Plan Regulations, maintaining the plans assets invested separately and independently from ITAÚ UNIBANCO HOLDING CONSOLIDATED.

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 155

| c) | Defined benefit plan

| I - | Main assumptions used in actuarial valuation of Retirement Plans

|  | 09/30/2018 |  | 09/30/2017
Discount rate (1) |  | 9.98% p.a. |  | 10.24% p.a.
Mortality table (2) |  | AT-2000 |  | AT-2000
|  | Itaú Experience |  | Itaú Experience
Turnover (3) |  | 2008/2010 |  | 2008/2010
Future salary growth |  | 5.04% to 7.12 % p.a. |  | 5.04% to 7.12 % p.a.
Growth of the pension fund and social security benefits |  | 4.00 % p.a. |  | 4.00 % p.a.
Inflation |  | 4.00 % p.a. |  | 4.00 % p.a.
Actuarial method (4) |  | Projected Unit Credit |  | Projected Unit Credit

(1) The adoption of this assumption is based on interest rates obtained from the actual interest curve in IPCA, for medium term liabilities of retirement plans sponsored by ITAÚ UNIBANCO HOLDING CONSOLIDATED. At 12/31/2017 assumption were adopted consistently with the economic scenario at the balance sheet date rate, considering the volatility of the interest markets and the models adopted;

(2) The mortality tables adopted correspond to those disclosed by Society of Actuaries (SOA), the North-American Entity which corresponds to Brazilian Institute of Actuarial Science (IBA), which reflects a 10% increase in the probabilities of survival compared to the respective basic tables. The life expectancy in years per the AT-2000 mortality table for participants aged 55 years is 27 and 31 years for men and women, respectively;

(3) The turnover assumption is based on the effective experience of ITAÚ UNIBANCO HOLDING CONSOLIDATED, resulting in the average of 2.4% p.a. based on the 2008/2010 experience;

(4) Using the Projected Unit Credit, the mathematical reserve is determined based on the current projected benefit amount multiplied by the ratio between the length of service in the company at the assessment date and the length of service that will be reached at the date when the benefit is granted. The cost is determined taking into account the current projected benefit amount distributed over the years that each participant is employed.

In case of benefits sponsored by foreign subsidiaries, actuarial assumptions adequate to the group of participants and the country's economic scenario are adopted.

Biometric/demographic assumptions adopted are consistent with the group of participants of each benefit plan, pursuant to the studies carried out by an independent external actuarial consulting company.

The main differences between the assumptions above and those adopted upon determination of the actuarial liability of defined benefit plans, for the purposes of recording in the balance sheet of the closed-end private pension entities (EFPCs) that manage them, are the discount rate and the actuarial method. Regarding the discount rate assumption, EFPCs adopt a rate consistent with the flow of receipts/payments, in accordance with the study conducted by an independent external consulting company. Regarding the actuarial method, the aggregate method is adopted, by which the mathematical reserve is defined based on the difference between the present value of the projected benefit and the present value of future contributions, subject to the methodology defined in the respective actuarial technical note.

II - Risk Exposure

Due to its defined benefit plans, ITAÚ UNIBANCO HOLDING CONSOLIDATED is exposed to a number of risks, the most significant ones are:

- Volatility of assets

The actuarial liability is calculated by adopting a discount rate defined based on the income related to securities issued by the Brazilian treasury (government securities). If the actual income related to plan investments is lower than expected, this may give rise to a deficit. The plans have a significant percentage of fixed-income securities pegged to the plan commitments, aimed at minimizing volatility and short and medium term risk.

- Changes in investment income

A decrease in income related to public securities will imply a decrease in the discount rate and, therefore, will increase the plan’s actuarial liability. The effect will be partially offset by the recognition of these securities at market value.

- Inflation risk

Most of the plan benefits are pegged to the inflation rates, and a higher inflation will lead to higher obligations. The effect will also be partially offset because a significant portion of the plan assets is pegged to government securities restated at the inflation rate.

Itaú Unibanco Holding S.A. – Complete Financial Statements – September 30, 2018 | 156

- Life expectancy

Most of the plan obligations are to provide life benefits, and therefore an increase in life expectancy will result in increased plan liabilities.

III –Management of defined benefit plan assets

The general purpose of managing EFPC funds is to search for a long term balance between assets and obligations to pay of retirement benefits, by exceeding the actuarial targets (discount rate plus benefit adjustment index, established in the plan regulations).

Regarding the assets guaranteeing the actuarial liability reserves, management should ensure the payment capacity of retirement benefits in the long term by avoiding the risk of mismatching assets and liabilities in each pension plan.

At 09/30/2018 and 09/30/2017 the allocation of plan assets and the allocation target for 2018, by type of asset, are as follows:

|  | Fair value |  |  | % Allocation
Types |  | 09/30/2018 |  |  | 09/30/2017 |  |  | 09/30/2018 |  |  | 09/30/2017 |  |  | 2018 Target
Fixed income securities |  |  | 17,382,507 |  |  |  | 16,072,635 |  |  |  | 96.01 | % |  |  | 94.44 | % |  | 53% to 100%

Control and capital management units, in turn, support the ITAÚ UNIBANCO HOLDING CONSOLIDATED’s management by monitoring and analyzing risk and capital.

The principles providing the foundations for management of risk, risk appetite and guidelines on how ITAÚ UNIBANCO HOLDING CONSOLIDATED’s employees should behave on the day-to-day for decision-making purposes are as follows:

| · | Sustainability and Client Satisfaction: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s vision is to be the leading bank in sustainable performance and client satisfaction and, therefore, it is committed to creating shared value to employees, clients, stockholders, and society, ensuring the continuity of business.

The Risk Culture is described below.

| · | Risk Pricing: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s acts and assumes risks in business it knows and understands, avoiding risks that are unknown to the institution or that do not have a competitive edge, therefore carefully assessing the risk-return ratio.

These principles lay down the basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED’s guidelines by helping employees to consciously understand, identify, measure, manage and mitigate risks.

In addition to policies, procedures and processes, the risk culture strengthens the individual and collective responsibility of employees in the management of risks inherent in the activities performed individually, respecting the ethical way of managing business.

ITAÚ UNIBANCO HOLDING CONSOLIDATED promotes the risk culture, emphasizing the behavior that will help people in any level of the institution to assume and manage risk on a responsible way. With these principles disseminated by the institution, there is an incentive for the risk to be understood and discussed frankly, maintained within the limits established for risk appetite, and so that each employee, regardless of their position, area or function, also assumes responsibility for managing risks of their business.

ITAÚ UNIBANCO HOLDING CONSOLIDATED also provides channels for reporting operational failures, internal or external frauds, and conflicts in the work environment or situations that might cause disruptions and/or losses to the institution or adversely affect clients. Every employee and third party is responsible for reporting any issues on a promptly basis, as soon as they become aware of the fact.

The Board of Directors is the primary body in the establishment of guidelines, policies, and approval level for risk and capital management. The Capital and Risk Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in the performance of its roles related to capital and risk management. In the executive level, panels, presided over by the Chief Executive Officer (CEO) of Itaú Unibanco, are responsible for capital and risk management and which decisions are monitored in the scope of CGRC.

Additionally, the institution has panels, which exercise the responsibilities delegated in capital and risk management, presided over by the Executive Vice-President of the Risk and Finance Department (ARF).

Additionally, to support this structure, ARF is structured by specialized officers. The purpose is to ensure, on an independent and centralized basis, that risks and capital of the institution are management in compliance with established the policies and procedures.

A detailed description of this structure may be found in the Consolidated Annual Report, in the section our Risk Management. The Consolidated Annual Report is available on the website www.itau.com.br/investor-relations, the section Itaú Unibanco.

The risk management organizational structure of Itaú Unibanco is in compliance with the regulations in force in Brazil and abroad, and in line with the best practices of the market. The responsibilities for risk management at Itaú Unibanco are structured in accordance with three defense lines, to wit:

| · | in the first defense line, business areas and back-office corporate areas manage risks originated by them, through their identification, assessment, control and report thereof;

| · | in the second defense line, an independent unit controls risks on a centralized basis, aiming at assuring that the risks of ITAÚ UNIBANCO HOLDING CONSOLIDATED are managed in accordance with the appetite for risk, and the policies and procedures established. Thus, the centralized control provides the Board of Directors and the executives with a global vision of exposures of ITAÚ UNIBANCO HOLDING CONSOLIDATED so as to optimize and expedite corporate decisions;

| · | in the third defense line, internal audit performs the independent assessment of the activities carried out in the institution, enabling top management to measure the adequacy of controls, effectiveness of risk management and compliance with internal rules and regulatory requirements.

Market Risk Management Policy is in line with the principles of Resolution nº. 3,464, issued by the National Monetary Council (CMN) and posterior amendments, being a set of principles that drive strategy towards control and management of market risk of all institution.

ITAÚ UNIBANCO HOLDING CONSOLIDATED’s market risk management strategy is aimed at balancing corporate business goals, taking into account, among other things:

| · | Political, economic and market conditions;

| · | Portfolio profile of ITAÚ UNIBANCO HOLDING CONSOLIDATED;

| · | Expertise within the group to support operations in specific markets.

The purpose of market risk control of ITAÚ UNIBANCO HOLDING CONSOLIDATED structure is:

| · | Providing visibility and assurance to all executive levels that the assumption of market risks is in line with ITAÚ UNIBANCO HOLDING CONSOLIDATED risk-return objective;

| · | Promoting a disciplined and informed discussion on the global risk profile and its evolution over time;

| · | Increasing transparency on the way the business seeks to optimize results;

| · | Providing early warning mechanisms in order to make the effective risk management easier, without jeopardizing the business purposes; and

| · | Monitoring and avoiding risk concentration.

The market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of: (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and warnings, (iii) application, analysis and tests of stress scenarios, (iv) risk reporting for individuals responsible within the business areas, in compliance with governance of ITAÚ UNIBANCO HOLDING CONSOLIDATED, (v) monitoring of actions required for adjustment of positions and/or risk levels to make them feasible, and (vi) support to the launch of new financial products with security.

The National Monetary Council (CMN) has regulations that establish the segregation of exposure to market risk at least in the following categories: interest rate, exchange rate, shares and commodities. Brazilian inflation indexes are treated as a group of risk indicators and receive the same treatment given to other risk indicators.

The structure of limits and warnings is in line with the Board of Directors’ guidelines, and it is reviewed and approved on an annual basis. This structure has specific limits aiming at improving the risk monitoring and understanding process, and at avoiding concentration. These limits are quantified by assessing the forecasted results of the balance sheet, size of stockholders’ equity, liquidity, market complexity and volatility, as well as the institution’s appetite for risk.

II – Credit risk

ITAÚ UNIBANCO HOLDING CONSOLIDATED understands credit risk as the possibility of losses arising from the breach by the borrower, issuer or counterparty of the respective agreed-upon financial obligations, the devaluation of loan agreement due to downgrading of the borrower’s, the issuer’s, the counterparty’s risk rating, the reduction in gains or compensation, the advantages given upon posterior renegotiation and the recovery costs.

There is a credit risk control and management structure, centralized and independent from the business units, that provides for operational limits and risk mitigating mechanisms, in addition for establishing processes and tools to measure, monitor and control the credit risk inherent in all products, portfolio concentrations and the impacts from potential changes in the economic environment.

ITAÚ UNIBANCO HOLDING CONSOLIDATED establishes its credit policy based on internal factors, such as client rating criteria, performance of and changes in portfolio, default levels, return rates, and allocated economic capital, among others, also considering external factors, such as interest rates, market default indicators, inflation, changes in consumption, among others.

To protect the institution against losses arising from loan operations, ITAÚ UNIBANCO HOLDING CONSOLIDATED considers all aspects that determine the client’s credit risk to define a provision level that is adequate with the risk incurred in each operation. For each operation, the assessment and rating of the client or economic group, the operation rating, and the possible existence of past-due amounts are taken into account and the volume of the regulatory provision is determined.

In compliance with CMN Resolution 3,721, the document “Public Access Report – Credit Risk“, which includes the guidelines established by the institutional credit risk control policy can be viewed at www.itau.com.br/investor-relations, under Itaú Unibanco, Corporate Governance, Regulations and Policies.

IV – Liquidity risk

Liquidity risk is defined as the institution’s possibility of not being able to efficiently meet its expected and unexpected obligations, both current and future, including those arising from the pledged guarantees, without affecting its daily operations and without incurring significant losses.

The control over liquidity risk is carried out by an area independent from the business area and responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different horizons of time, and monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING CONSOLIDATED operates. All activities are subject to verification by the independent validation, internal control and audit areas.

In compliance with Circular Letter n° 3,775 of BACEN, bank holding total assets over R$ 100 billion are required to report a standardized Liquidity Coverage Ratio (LCR) to the Central Bank of Brazil on a monthly basis as of October 2015. This ratio is calculated based on a methodology defined by the Central Bank of Brazil itself, and is in line with international guidelines of Basel.

The summarized index calculation is presented in the table below. In 2018, the index minimum requirement is 90%. Further details on the LCR for the period may be accessed at www.itau.com.br/investor-relations, section Reports, Pillar 3 and Global Systemically Important Banks, Risk and Capital Management Report.

Information on the Liquidity Coverage Ratio (LCR) |  | Third quarter of 2018 |
|  | Total Adjusted Amount(1) |
Total high-quality liquid assets (2) |  |  | 179,507,182 |
Total potential cash outflows (3) |  |  | 105,057,841 |
Liquidity Coverage Ratio (%) |  |  | 170.9 | %

(1) Corresponds to the amount calculated after the application of weighting factors and limits established by BACEN Circular nº. 3,749.

(2) HQLA - High quality liquid assets: balance in the stock, which in certain cases weighted by a discount factor, of assets that remain liquid in the markets during a stress period, which can be easily converted into cash and that pose low risk.

(3) Potential cash outflows calculated in standardized stress, determined by Circular nº. 3,749 (outflows), subtracted from (i) potential cash inflows calculated under standardized stress, set forth by Circular nº. 3,749 and (ii) 75% x Outflows, whichever is lower.

Mitigation actions concerning the social and environmental risk are carried out by mapping processes, risks and controls, monitoring new regulations on the subject, and recording any occurrences in internal databases. In addition to identification, the phases of prioritization, response, monitoring and reporting of assessed risks supplement this risk monitoring at ITAÚ UNIBANCO HOLDING CONSOLIDATED.

The Social and environmental risk management is carried out by the first line of defense in its daily operations, with the technical assessment of the legal and risk areas, which have a technical dedicated team. Business units also have governance for approval of new products, which includes the assessment of the social and environmental risk, therefore ensuring compliance with this requirement for all new products approved by the institution. Governance still has the Social and Environmental Risk Committee, which main duty is to guide the institutional understanding related to exposure to social and environmental risk for the institution’s activities.

Report on review of interim financial statements

To the Board of Directors and Stockholders

Itaú Unibanco Holding S.A.

Introduction

We have reviewed the accompanying interim financial statements of Itaú Unibanco Holding S.A. (parent Company), which comprise the balance sheet as at September 30, 2018 and the related statements of income, changes in stockholders' equity and cash flows for the nine-month period then ended, as well as the accompanying consolidated interim financial statements of Itaú Unibanco Holding S.A. and its subsidiaries (“Consolidated”), which comprise the consolidated balance sheet as at September 30, 2018 and the related consolidated statements of income and cash flows for the nine-month period then ended, and a summary of significant accounting policies and other explanatory information.

Management is responsible for the preparation and fair presentation of the parent company and consolidated interim financial statements in accordance with accounting practices adopted in Brazil, applicable to institutions authorized to operate by the Brazilian Central Bank (BACEN). Our responsibility is to express a conclusion on these interim financial statements based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Review Engagements (ISRE 2410- Review of Interim Financial Information Performed by the Independent Auditor of the Entity). A review of interim financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Brazilian and International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the parent company and

consolidated interim financial statements

Based on our review, nothing has come to our attention that causes us to believe that the parent company and the consolidated interim financial statements referred to above do not present fairly, in all material respects, the financial position of Itaú Unibanco Holding S.A. and Itaú Unibanco Holding S.A and its subsidiaries as at September 30, 2018 and the parent company financial performance and cash flows, as well as the consolidated financial performance and the consolidated cash flows, for the nine-month period then ended, in accordance with accounting practices adopted in Brazil, applicable to institutions authorized to operate by the Brazilian Central Bank.
