As a listed company with shares traded on the above mentioned stock exchanges in Brazil and the United States, it is subject to the rules and oversight of the local authorities that regulate the respective capital markets: the Brazilian Securities and Exchange Commission (Comissão de ValoresMobiliários—CVM) and Securities and Exchange Commission (SEC) respectively, including the rules relative to Corporate Governance.

In addition, as a holding company, controlling a range of companies acting in various segments of the market, it includes under its conglomerato subsidiaries which are subject to the rules of the respective regulatory and self-regulatory authorities (if signatories) for these sectors, such as, among others, the Brazilian Federation of Banks (FEBRABAN), the National Council of Private Insurance (CNSP), Superintendency of Private Insurance (SUSEP), the Complementary Pension Superintendence (PREVIC), the Brazilian Financial and Capital Markets Entities Association (ANBIMA) and the Brazilian Association of Listed Companies (ABRASCA). In addition, the subsidiaries that engage in activities subject to inspection in other countries are supervised by the respective local regulatory bodies.

In Brazil, one of the principal regulations applicable to Itaú Unibanco reflects the adherence to B3’s Corporate Governance Level 1 listing, to which the Company signed up on a voluntary basis in 2001. Pursuant to Level 1 listing rules, Itaú Unibanco must adopt differentiated practices of Corporate Governance, such as greater transparency in disclosure to the market, maintenance of a minimum free float and share dispersion via public offerings of shares, respecting the interests of the minority stockholders. In addition, Itaú Unibanco is a signatory to the ABRASCA’s Code of Self-Regulation and Good Practices for Publicly-Held Companies and is constantly evolving its Corporate Governance practices, acting beyond the contents of regulatory and self-regulatory standards.

In the United States, Itaú Unibanco is subject to the Sarbanes-Oxley Act of 2002, and also the NYSE and SEC requirements applicable to foreign issuers, among them the necessity of establishing an Audit Committee and validation of the Company’s internal controls and financial statements.

Itaú Unibanco’s vision is to be the leading bank in sustainable performance and customer satisfaction.

For Itaú Unibanco, sustainable performance is to create shared value for employees, clients, stockholders and society, ensuring the longevity of the business.

One of the ways of creating value to stockholders is the adoption of best practices of Corporate Governance, a continuous and long-term process focused on the Company’s sustainable performance.

The above mentioned committees maintain a relationship with the Board of Directors, being their members elected or nominated by this body, with the purpose of creating the conditions for the uniform handling and systemization of matters of strategic relevance and control of Itaú Unibanco. The Board of Directors and the Committees operate as joint bodies, seeking to arrive at a consensus through dialogue and the systemic view which characterize Itaú Unibanco’s management.

The process for appointing those who will make up the Board of Directors and the Executive Board of the companies of the Itaú Unibanco Conglomerate in Brazil and overseas should be based on the appointment, in each company, of management members that directly or indirectly perform the activities related to their corporate purpose or supporting activities.

6.1. General Stockholders’ Meetings

The supreme body of the Company is the General Meeting, which brings stockholders together, either on an ordinary or extraordinary basis, through a convening notice as called for under law.

The Annual General Stockholders’ Meeting is held in the first four months of every year, for examination, discussion and voting of the financial statements reported by management, decision on the allocation of the net income for the fiscal year, payout of dividends and election of members to the Board of Directors and the Fiscal Council.

In order to promote the renovation of members on the Board of Directors, the Corporate Bylaws of Itaú Unibanco provides for the ineligibility to the Board of Directors of people more than 70 years of age.

6.2.1. Independent Member of the Board of Directors

The independence of the Board Members is designed to safeguard the Company’s interests and those of its minority stockholders, to foster the debate of ideas eventually different to those of the Directors related to the controlling group. In this context, the Internal Charter of the Board of Directors rules that the independent members may meet to examine specific themes relevant to the Company, reporting to the Chairman or Co-chairmen of the Board on the matters discussed and any suggestions on measures to be adopted.

7. STOCKHOLDERS’ RIGHTS

7.1. Dividends Policy

Since 1980, Itaú Unibanco has maintained as its dividend distribution policy the monthly payout of dividends and complementary semi-annual and annual payments.

Every fiscal year, stockholders are entitled to receive as a mandatory dividend, an amount of not less than twenty-five percent (25%) of net income determined in the same fiscal year, adjusted by the reduction or addition of the amounts specified in items “a” and “b” of subsection I of Article 202 of Corporate Law and pursuant to subsections II and III of the same legal provision.

In addition to the mandatory dividend, the Board of Directors may (i) propose to the Annual General Stockholders’ Meeting the payout of dividends calculated on the basis of retained earnings, revenue reserves and, in some cases, capital reserves and (ii) establish the payment of interest on capital. Payment of interim dividends or interest on capital is an integral part of the mandatory dividend for the fiscal year. The amounts paid per share as dividends and/or interest on capital are the same for common and preferred shares.

In this context, the Board of Directors approved the payout of a minimum of 35% of the annual recurring net income, and the percentage to be distributed may change every year based on the Company’s profitability and capital demands, always considering the minimum distribution set forth in the Bylaws.

The Stockholder Remuneration Policy may be found on the Investor Relations website (www.itau-unibanco.com.br/ri > Itaú Unibanco > Corporate Governance > Rules and Policies).

7.1.1. Dividend Reinvestment Program

The Dividend Reinvestment Program (PRD) was launched in 2004, permitting the automatic investment of the dividends in the purchase of preferred or common shares. Any stockholder may participate in the PRD as an Itaú Unibanco S.A. current account holder, whether they are an individual or corporate entity.

Itaú Unibanco’s PRD was the first CVM registered and approved dividend reinvestment program of a Brazilian company, presenting the following advantages for Itaú Unibanco’s stockholders: (i) it offers a safe, efficient, systematic and organized share purchase alternative; (ii) allows the combination of individual share purchase offers with the offers of all the other stockholders of the same company which have adhered to the PRD, enabling an increase in investment volume and consequently a reduction in brokerage fees, if compared to a regular acquisition of shares; and (iii) it promotes a gradual increase in the interest in the capital stock of the Company and in distributed dividends.

7.2. Tag Along

The Tag Along is a minority stockholder defense mechanism (those stockholders not part of the controlling group) which assures them a minimum price to be paid for their shares in an eventual sale of control of the Company.

Brazilian corporate legislation requires that, in the event of the sale of a listed company, the acquiring party must make a public offering for the acquisition of the common shares of the non-controlling stockholders at a minimum price equal to eighty percent (80%) of the amount paid per share to the controlling group. A General Meeting of Itaú Unibanco, held in 2002, extended to the holders of preferred shares the same tag along right. Thus, at Itaú Unibanco, the tag along is a right granted not only to the holders of common shares (as prescribed in law), but also to the holders of the preferred shares.

8. TRANSPARENCY

8.1. Investor Relations

The prime objective of the Investor Relations department (IR) is to transparently and accessibly disseminate information on Itaú Unibanco on which an investment in shares and securities of its own issue can be based. Its role is to establish a communication channel between the company’s management and the members of the domestic and international financial community, always seeking to create long-term value to stockholders. The Investor Relations department (IR) carried out a combination of activities that should contribute to the fair evaluation of the company, enabling the investing public to take proper investment decisions.

In addition to the adoption of the Disclosure and Trading Policies, Itaú Unibanco has once again gone beyond the scope of the CVM requirements to establish, with best Corporate Governance practices in mind, a specific committee for policies management: the Disclosure and Trading Committee, made up of members of the Board of Directors and Executive Board. Its duties covers a range of internal initiatives for improving information flow and safeguarding the ethical conduct of its management and staff members, signatories to the policies.

8.4. Operating Rules for Treasury

In 2004, following a broad-based national and international survey of best Corporate Governance practices, Itaú Unibanco became the first Brazilian company to adopt, on a voluntary basis, Operating Rules for the Trading of Shares for Treasury (“Rules”). These Rules now govern trading in shares issued by Itaú Unibanco on stock exchanges where its shares are eligible for trading.

Among the benefits of adopting these Rules, the highlights are the reduction in operational, financial and strategic risk, the creation of an internal culture for these operations in the capital markets, the reduction in the possibility of market concentration or improper price fixing, the underscoring of the strategy for the repurchase of securities focused on the preservation of liquidity and value for stockholders.

9. COMPENSATION OF MANAGEMENT MEMBERS

9.1 INFORMATION ABOUT COMPENSATION OF MANAGEMENT MEMBERS

The Company`s compensation strategy adopts clear and transparent processes, aimed at complying with applicable regulation and the best national and international practices, as well as ensuring consistency with Itaú Unibanco’s risk management policy.

The Company discloses in its Reports, available on the Investor Relations website (www.itau-unibanco.com.br/ri), information about the compensation of management members, describing its compensation policy and practice, compensation plans, investments in shares, quotas and other securities, in addition to compensation mechanisms and other relevant information.

9.2 . STOCK OPTION PLAN

Itaú Unibanco was one of the first Brazilian companies to grant stock options to its management members (since 1995) so as to allow the alignment of the interests of its executives with those of Itaú Unibanco in so far as they share the same risks and gains provided by the appreciation of the Company’s shares.

The purpose of the Stock Option Plan is to make the executives parties to the medium and long-term development of the Company, thus allowing them to participate in the enhancement in value that their work and dedication has brought to the shares of the Company.

Since 2012, no option has been granted within the scope of the Stock Option Plan. For further information on Changes in the plan, see Note 22 to the financial statements under IFRS.

9.3. STOCK GRANT PLAN

At the Extraordinary Stockholders’ General Meeting held on April 19, 2017, Itaú Unibanco approved the Stock Grant Plan for the purpose of consolidating the rules related to long-term incentive programs that involve the granting of shares to management members and employees of the Company and its direct and indirect subsidiaries in accordance with CVM Instruction No. 567/15.

By means of the Stock Grant Plan, Itaú Unibanco intends to keep the interests of the Company’s management members and employees and of its direct and indirect subsidiaries in line with the interests of stockholders and the Company itself. To this end, the Stock Grant Plan gives these stakeholders the opportunity of becoming stockholders of Itaú Unibanco, enabling them to share short, medium and long-term risks.

The Stock Grant Plan also allows for the attraction and retention of talented professionals since it also provides for performance-based stock granting programs. Accordingly, it is possible to encourage a sustainable running of the business, always in line with the interests of stockholders.

The transactions between Itaú Unibanco and related parties are carried out according to the legal and ethical rules.

Itaú Unibanco assures the equality and transparency of the transactions through the medium of the Policy for Transactions with Related Parties wherein rules are established and procedures consolidated for these transactions.
