Note 2 – Significant accounting policies
 
2.1.
Basis of preparation
The Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING were prepared in accordance with the requirements and guidelines of the National Monetary Council (CMN), which require that as from December 31, 2010 annual Consolidated Financial Statements are prepared in accordance with the International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB).
In the preparation of these Consolidated Financial Statements, ITAÚ UNIBANCO HOLDING adopted the criteria for recognition, measurement and disclosure established in the IFRS and in the interpretations of the International Financial Reporting Interpretation Committee (IFRIC).
The information in the financial statements and accompanying notes evidence all relevant information inherent in the financial statements, and only them, which are consistent with information used by management in its administration.
 
2.2.
New accounting standards changes and interpretations of existing standards
 
 
a)
Accounting standards applicable for period ended December 31, 2021
 
   
Interest Rate Benchmark Reform (IBOR Reform) Phase II - Amendments to IFRS 4 – Insurance Contracts, IFRS7 – Financial Instruments: Disclosures, IFRS 9 – Financial Instruments, IFRS 16 – Leases and IAS 39 – Financial Instruments: Recognition and Measurement: Phase II of the inter-bank offered rates reform used as market benchmarks (IBOR). The amendments are summarized as:
 
   
Changes in financial assets and liabilities: Practical expedient that allows to replace, as a consequence of the reform, the effective interest rate of a financial asset or financial liability with a new economically equivalent rate, without derecognition of the contract;
 
   
Hedge accounting: End of exemptions for evaluating the effectiveness of hedge relationships (Phase I) with recognition in Profit or Loss of the ineffective portion, creation of
sub-portfolios
to segregate contracts with the amended rates for hedges of group items,
24-month
term for identification and segregation of new risk based on changes in interest rates, and updates of hedge documentation;
 
   
Disclosure: Requirements about the disclosure of risks to which the entity is exposed by the reform, risk management and evolution of the IBORs transition.
These amendments are effective for years beginning on January 1st, 2021. ITAÚ UNIBANCO HOLDING is exposed mainly to Libor and Euribor rates in hedge accounting structures and financial assets and liabilities, including derivatives. Agreements linked to Libor, due to its extinction will be (i) updated to an alternative rate plus spread; or (ii) settled in advance should there be no agreement between the parties. The main risks identified by IBOR Reform are:
 
   
Change in the hierarchy level for measuring the fair value of contracts that remain referenced in IBORs under extinction due to the expectation of reduction in the liquidity of these contracts;
 
   
Effect as a result of the change of financial instruments in which the renegotiated cash flows are not economically equivalent to the original cash flows; and
 
   
Early settlement of contracts where there is no agreement between the parties.
 
To mitigate the risks associated with IBOR Reform in standardized agreements, ITAÚ UNIBANCO HOLDING will assume the update of rates made by the respective clearing houses with the accretion of a spread so that the restated cash flows are economically equivalent to the original cash flows. The fallback clauses protocols suggested by international self-regulatory entities (International Swaps and Derivatives Association - ISDA) will be adopted. The other agreements will be negotiated between the parties seeking approach to the model adopted for standardized agreements and they will be gradually adjusted until the date expected for the end of disclosure of Libor. Accordingly, ITAÚ UNIBANCO HOLDING does not expect significant impacts resulting from the IBOR Reform.
 
 
b)
Accounting standards recently issued and applicable in future periods
 
   
IFRS 17 – Insurance Contracts: The pronouncement replaces IFRS 4 – Insurance Contracts and presents three approaches for valuation:
 
   
General Model: applicable to all contracts without direct participation features;
 
   
Premium Allocation Approach (PAA): applicable to contracts with term is up to 12 months or when it produces results similar to those that would be obtained if the general model was used. It is more simplified than the general model;
 
   
Variable Fee Approach: applicable to insurance contracts with direct participation features, the insurance contracts which are substantially investment related service contracts under which an entity promises an investment return based on underlying items.
Insurance contracts must be recognized based on an analysis of four components:
 
   
Expected Future Cash Flows: estimate of all components of cash flow of the contract, considering inflows and outflows;
 
   
Risk Adjustment: estimate of offset required for differences that may occur between cash flows;
 
   
Contractual Margin: difference between any amounts received before the beginning of the contract coverage and present value of cash flows estimated at the beginning of the contract;
 
   
Discount: projected cash flows must be discounted to present value, to reflect the time value of money, at rates that reflect the characteristics of the respective flows.
This standard is effective for annual periods beginning January 1
st
, 2023. Possible impacts are being assessed and the assessment will be completed by the date this standard comes into force.
 
   
Amendments to IAS 1 – Presentation of Financial Statements – Requires that only information about material accounting policies are disclosed, eliminating disclosures of information that duplicate or summarize IFRS requirements. These amendments are effective for the years beginning January 1
st
, 2023 and they have no financial impacts. Analyzes regarding changes in disclosure will be completed by the date the standard becomes effective.
 
   
Amendments to IAS 8 - Accounting Policies, Changes in Accounting Estimates and Errors – Includes the definition of accounting estimates: monetary amounts subject to uncertainties in their measurement. Expected credit loss and the fair value of an asset or liability are examples of accounting estimates. This change is effective for the years beginning January 1
st
, 2023 and there are no impacts for the Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING.
 
   
Amendments to IAS 12 – Income Taxes – Clarifies that the exemption for accounting for deferred taxes arising from temporary differences generated in the initial recognition of assets or liabilities is no applicable to lease operations. These amendments are effective for years beginning January 1
st
, 2023. Possible impacts are being evaluated and will be completed by the date the standard becomes effective.
 
2.3.
Critical accounting estimates and judgments
The preparation of Consolidated Financial Statements in accordance with the IFRS requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent assets and liabilities at the date of the Financial Statements, due to uncertainties and the high level of subjectivity involved in the recognition and measurement of certain items. Estimates and judgments that present a significant risk and may have a material impact on the values of assets and liabilities are disclosed below. Actual results may differ from those established by these estimates and judgments.

a)
Consolidation
Subsidiaries are all those in which ITAÚ UNIBANCO HOLDING, either directly or through other subsidiaries, is the holder of partner rights that permanently ensure preponderance in corporate resolutions and the power to elect the majority of managers. The existence of control is assessed continuously. Subsidiaries are consolidated from the date control is established to the date on which it ceases to exist.
The consolidated financial statements are prepared using consistent accounting policies. Intercompany asset and liability account balances, income accounts and transaction values have been eliminated.
 
 
b)
Fair value of financial instruments not traded in active markets, including derivatives
The fair value of financial instruments, including derivatives that are not traded in active markets, is calculated by using valuation techniques based on assumptions that consider market information and conditions. The main assumptions are: historical data, information on similar transactions and pricing techniques. For more complex or illiquid instruments, significant judgment is necessary to determine the model used with the selection of specific inputs and, in certain cases, evaluation adjustments are applied to the model amount our price quoted for financial instruments that are not actively traded.
The methodologies used to estimate the fair value of certain financial instruments are described in Note 28.
 
 
c)
Effective interest rate
For the calculation of the effective interest rate, ITAÚ UNIBANCO HOLDING estimates cash flows considering all contractual terms of the financial instrument, but without consider future credit losses. The calculation includes all commissions paid or received between parties to the contract, transaction costs, and all other premiums or discounts.
Interest revenue is calculated by applying the effective interest rate to the gross carrying amount of a financial asset. In the case of purchased or originated credit impaired financial assets, the adjusted effective interest rate is applied, taking into account the expected credit loss, to the amortized cost of the financial asset.
 
 
d)
Modification of financial assets
The factors used to determine whether there has been substantial modification of a contract are: evaluation if there is a renegotiation that is not part of the original contractual terms, significant change to contractual cash flows and significant extensions of the term of the transaction due to the debtor’s financial constraints, significant change to the interest rate and change to the currency in which the transaction is denominated.
 
 
e)
Transfer and
write-off
of financial assets
When there are no reasonable expectations of recovery of a financial asset, considering historical curves, its total or partial
write-off
is carried out concurrently with the use of the related allowance for expected credit loss, with no effect on the Consolidated Statement of Income of ITAÚ UNIBANCO HOLDING. Subsequent recoveries of amounts previously written off are accounted for as income in the Consolidated Statement of Income.
Thus, financial assets are written off, either totally or partially, when there is no reasonable expectation of recovering a financial asset or when ITAÚ UNIBANCO HOLDING substantially transfers all risks and benefits of ownership and said transfer is qualified to be written off.
 
 
f)
Expected credit loss
The measurement of expected credit loss requires the application of significant assumptions and use of quantitative models. Management exercises its judgment in the assessment of the adequacy of the expected loss amounts resulting from models and, according to its experience, makes adjustments that may result from certain client’s credit condition or temporary adjustments resulting from situations or new circumstances that have not been reflected in the modeling yet.
The main assumptions are:
 
   
Term to maturity:
ITAÚ UNIBANCO HOLDING considers the maximum contractual period on which it will be exposed to financial instrument’s credit risk. However, the estimated useful life of assets that do not have fixed maturity date is based on the period of exposure to credit risk. Additionally, all contractual terms are taken into account when determining the expected life, including prepayment and rollover options.
 
   
Prospective information:
IFRS 9 requires a balanced and impartial estimate of credit loss that includes forecasts of future economic conditions. ITAÚ UNIBANCO HOLDING uses macroeconomic forecasts and public information with projections prepared internally to determine the impact of these estimates on the calculation of expected credit loss. Main prospective information used to determine the expected loss is related to Selic Rate, Credit Default Swap (CDS), unemployment rate, Gross Domestic Product (GDP), wages, industrial production and retail sales.
 
   
Macroeconomic scenarios:
This information involves inherent risks, market uncertainties and other factors that may give rise to results different from expected.
 
   
Probability-weighted loss scenarios:
ITAÚ UNIBANCO HOLDING uses weighted scenarios to determine credit loss expected over a suitable observation horizon adequate to classification in stages, considering the projection based on economic variables.
 
   
Determining criteria for significant increase or decrease in credit risk:
in each period of the consolidated financial statements, ITAÚ UNIBANCO HOLDING assesses whether the credit risk of a financial asset has increased significantly since the initial recognition using absolute and relative triggers (indicators). The migration of the financial asset to an earlier stage occurs with a significant reduction in credit risk, mainly characterized by the
non-activation
of credit deterioration triggers for at least 6 months.
ITAÚ UNIBANCO HOLDING assesses whether the credit risk has significantly increased on an individual or collective basis. For collective assessment purposes, financial assets are grouped based on characteristics of shared credit risk, considering the type of instrument, credit risk classifications, initial recognition date, remaining term, industry, geographical location of the counterparty, among other significant factors.
Details on the expected credit loss and criteria for a significant increase or decrease in credit risk are in Note 32.
 
 
g)
Goodwill impairment
The review of goodwill due to impairment reflects the Management’s best estimate for future cash flows of Cash Generating Units (CGU), with the identification of the CGU and estimate of their fair value less costs to sell and/or value in use.
To determine this estimate, ITAÚ UNIBANCO HOLDING adopts the discounted cash flow methodology for a period of 5 years, macroeconomic assumptions, growth rate and discount rate.
The discount rate generally reflects financial and economic variables, such as the risk-free interest rate and a risk premium.
Cash-Generating Units or CGU groups are identified at the lowest level at which goodwill is monitored for internal management purposes.
 
 
h)
Deferred income tax and social contribution
Deferred tax assets are recognized only in relation to deductible temporary differences, tax losses and social contribution loss carryforwards for offset only to the extent that it is probable that ITAÚ UNIBANCO HOLDING will generate future taxable profit for its use. The expected realization of deferred tax assets is based on the projection of future taxable profits and technical studies, as disclosed in Note 24.
 
 
i)
Defined benefit pension plan
The current amount of pension plans is obtained from actuarial calculations, which use assumptions such as discount rate, which is appropriated at the end of each year and used to determine the present value of estimated future cash outflows. To determine the appropriate discount rate, ITAÚ UNIBANCO HOLDING considers the interest rates of National Treasury Notes that have maturity terms similar to the terms of the respective liabilities.
The main assumptions for Pension plan obligations are partly based on current market conditions. Additional information is disclosed in Note 26.
 
 
j)
Provisions, contingencies and legal obligations
ITAÚ UNIBANCO HOLDING periodically reviews its contingencies. These contingencies are evaluated based on management´s best estimates, taking into account the opinion of legal counsel when there is a likelihood that financial resources will be required to settle the obligations and the amounts may be reasonably estimated.
Contingencies classified as probable losses are recognized in the Balance Sheet under Provisions.
Contingent amounts are measured using appropriate models and criteria, despite the uncertainty surrounding the ultimate timing and amounts. Additional information is described in Note 29.
 
 
k)
Technical provisions for insurance and private pension
Technical provisions are liabilities arising from obligations of ITAÚ UNIBANCO HOLDING to its policyholders and participants. These obligations may be short term liabilities (property and casualty insurance) or medium and long term liabilities (life insurance and pension plans).
The determination of the actuarial liability is subject to several uncertainties inherent in the coverage of insurance and pension contracts, such as assumptions of persistence, mortality, disability, life expectancy, morbidity, expenses, frequency and severity of claims, conversion of benefits into annuities, redemptions and return on assets.
The estimates for these assumptions are based on the historical experience of ITAÚ UNIBANCO HOLDING, benchmarks and the experience of the actuary, in order to comply with best market practices and constantly review of the actuarial liability. The adjustments resulting from these continuous improvements, when necessary, are recognized in the statement of income for the corresponding period. Additional information is described in Note 27.

II.
Business combinations
In general, a business consists of an integrated set of activities and assets that may be conducted and managed so as to provide a return, in the form of dividends, lower costs or other economic benefits, to investors or other stockholders, members or participants. If there is goodwill in a set of activities and assets transferred, it is presumed to be a business.
The acquisition method is used to account for business combinations, except for those classified as under common control.
Acquisition cost is measured at the fair value of the assets transferred, equity instruments issued and liabilities incurred or assumed at the acquisition date. Acquired assets and assumed liabilities and contingent liabilities identifiable in a business combination are initially measured at fair value at the date of acquisition, regardless of the existence of non-controlling interests. When the amount paid, plus non-controlling interests, is higher than the fair value of identifiable net assets acquired, the difference will be accounted for as goodwill. On the other hand, if the difference is negative, it will be treated as negative goodwill and the amount will be recognized directly in income.
 
 
III.
Goodwill
Goodwill is not amortized, but its recoverable value is assessed semi-annually or when there is an indication of impairment loss using an approach that involves the identification of Cash Generating Units (CGU) and the estimate of its fair value less the cost to sell and/or its value in use.
The breakdown of intangible assets is described in Note 14.
 
 
IV.
Capital Transactions with
non-controlling
stockholders
Changes in an ownership interest in a subsidiary, which do not result in a loss of control, are accounted for as capital transactions and any difference between the amount paid and the carrying amount of non-controlling stockholders is recognized directly in consolidated stockholders’ equity.
 
 
b)
Foreign currency translation
 
 
I.
Functional and presentation currency
The Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING are presented in Brazilian Reais, its functional and presentation currency. For each subsidiary, joint venture or investment in associates, ITAÚ UNIBANCO HOLDING defines the functional currency as the currency of the primary economic environment in which the entity operates.
 
 
II.
Foreign currency operations
Foreign currency operations are translated into the functional currency using the exchange rates prevailing on the dates of the transactions. Foreign exchange gains and losses are recognized in the consolidated statement of income, unless they are related to cash flow hedges and hedge of net investment in foreign operations, which are recognized in stockholders’ equity.
 
 
c)
Cash and cash equivalents
Defined as cash and current accounts with banks, shown in the Consolidated Balance Sheet under the heading Cash, Interbank Deposits, Securities purchased under agreements to resell (Collateral Held) and Voluntary investments with the Central Bank of Brazil with original maturities not exceeding 90 days.
 
 
d)
Financial assets and liabilities
Financial assets and liabilities are offset against each other and the net amount is reported in the Balance Sheet only solely when there is a legally enforceable right to offset them and the intention to settle them on a net basis, or to simultaneously realize the asset and settle the liability.
 
I - Initial recognition and derecognition
Financial assets and liabilities are initially recognized at fair value and subsequently measured at amortized cost or fair value.
Regular purchases and sales of financial assets are recognized and derecognized, respectively, on the trading date.
Financial assets are partially or fully derecognised when:
 
   
the contractual rights to the cash flows of the financial asset expire, or
 
   
ITAÚ UNIBANCO HOLDING transfers the financial asset and this transfer qualifies for derecognition.
The financial liabilities are derecognized when they are extinguished, i.e., when the obligation specified in the contract is discharged, cancelled or expires.
Derecognition of financial assets
Financial assets are derecognized when ITAÚ UNIBANCO HOLDING substantially transfers all risks and benefits of its property. In the event it is not possible to identify the transfer of all risks and benefits, the control should be assessed to determine the continuous involvement related to the transaction.
If there is a retention of risks and benefits, the financial asset continues to be recorded and a liability is recognized for the consideration received.
II - Classification and subsequent measurement of financial assets
Financial assets are classified in the following categories:
 
   
Amortized cost: used when financial assets are managed to obtain contractual cash flows, consisting solely of payments of principal and interest;
 
   
Fair value through other comprehensive income: used when financial assets are held both for obtaining contractual cash flows, consisting solely of payments of principal and interest, and for sale;
 
   
Fair value through profit or loss: used for financial assets that do not meet the aforementioned criteria.
The classification and subsequent measurement of financial assets depend on:
 
   
The business model under which they are managed;
 
   
The characteristics of their cash flows (Solely Payment of Principal and Interest Test – SPPI Test).
Business model:
represents how financial assets are managed to generate cash flows and does not depend on the Management’s intention regarding an individual instrument. Financial assets may be managed with the purpose of: i) obtaining contractual cash flows; ii) obtaining contractual cash flows and sale; or iii) others. To assess business models, ITAÚ UNIBANCO HOLDING considers risks that affect the performance of the business model; how the managers of the business are compensated; and how the performance of the business model is assessed and reported to Management.
When a financial asset is subject to business models i) or ii) the application of the SPPI Test is required.
SPPI Test:
assessment of cash flows generated by a financial instrument for the purpose of checking whether they represent solely payments of principal and interest. To fit into this concept, cash flows should include only consideration for the time value of money and credit risk. If contractual terms introduce risk exposure or cash flow volatilities, such as exposure to changes in prices of equity instruments or prices of commodities, the financial asset is classified at fair value
through profit or loss. Hybrid contracts must be assessed as a whole, including all embedded characteristics. The accounting of a hybrid contract that contains an embedded derivative is performed on a joint basis, i.e. the whole instrument is measured at fair value through profit or loss.
Amortized cost
Amortized cost is the amount for which a financial asset or liability is measured at its initial recognition, plus adjustments made under the effective interest method, less amortization of principal and interest, and any provision for expected credit loss.
Fair value
Fair value is the price that would be received for the sale of an asset or that would be paid for the transfer of a liability in an orderly transaction between market players on the measurement date.
ITAÚ UNIBANCO HOLDING classifies the fair value hierarchy according to the relevance of data observed in the measurement process.
Details of the fair value of financial instruments, including Derivatives, and of the hierarchy of fair value are given in Note 28.
The adjustment to fair value of financial assets and liabilities is recognized:
 
   
In stockholders’ equity for financial assets and liabilities measured at fair value through other comprehensive income; and
 
   
In the Consolidated Statement of Income, under the heading Income of Financial Assets and Liabilities at Fair Value through Profit or Loss, for the other financial assets and liabilities.
Average cost is used to determine the gains and losses realized on disposal of financial assets at fair value, which are recorded in the Consolidated Statement of Income as Interest and similar income and Income of Financial Assets and Liabilities at Fair Value through Profit or Loss. Dividends on assets at fair value through other comprehensive income are recognized in the Consolidated Statement of Income as Interest and similar income when it is probable that ITAÚ UNIBANCO HOLDING’s right to receive such dividends is assured.
Equity instruments
An equity instrument is any contract that evidences a residual interest in an entity’s assets, after the deduction of all its liabilities, such as Shares and Units.
ITAÚ UNIBANCO HOLDING subsequently measures all its equity instruments at fair value through profit or loss, except when Management opts, on initial recognition, to irrevocably designate an equity instrument at fair value through other comprehensive income when it is held for a purpose other than only generating returns. When this option is selected, gains and losses on the fair value of the instrument are recognized in the Consolidated Statement of Comprehensive Income and are not subsequently reclassified to the Consolidated Statement of Income, even on sale. Dividends continue to be recognized in the Consolidated Statement of Income as Interest and similar income, when ITAÚ UNIBANCO HOLDING’s right to receive them is assured.
Gains and losses on equity instruments measured at fair value through profit or loss are accounted in the Consolidated Statement of Income.
Expected credit loss
ITAÚ UNIBANCO HOLDING makes a forward-looking assessment of the expected credit loss on financial assets measured at amortized cost or through other comprehensive income, loan commitments and financial guarantee contracts:
 
   
Financial assets:
loss is measured at present value of the difference between contractual cash flows and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive;
   
Loan commitments:
expected loss is measured at present value of the difference between contractual cash flows that would be due if the commitment was drawn down and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive;
 
   
Financial guarantees:
the loss is measured at the difference between the payments expected for refunding the counterparty and the amounts that ITAÚ UNIBANCO HOLDING expects to recover.
ITAÚ UNIBANCO HOLDING applies a three-stage approach to measuring the expected credit loss, in which financial assets migrate from one stage to the other in accordance with changes in credit risk.
 
   
Stage 1 – 12-month expected credit loss: represents default events possible within 12 months. Applicable to financial assets which are not credit impaired when purchased or originated;
 
   
Stage 2 – Lifetime expected credit loss of financial instrument: considers all possible default events. Applicable to financial assets originated which are not credit impaired when originated or purchased but for which credit risk has increased significantly; and
 
   
Stage 3 – Credit loss expected for
credit-impaired
assets: considers all possible default events. Applicable to financial assets which are credit impaired when purchased or originated. The measurement of assets classified in this stage is different from Stage 2 due to the recognition of interest income by applying the effective interest rate to amortized cost (net of provision) rather than to the gross carrying amount.
An asset will migrate between stages as its credit risk increases or decreases. Therefore, a financial asset that migrated to stages 2 and 3 may return to stage 1, unless it was purchased or originated credit impaired financial asset.
Macroeconomic scenarios
Forward-looking information is based on macroeconomic scenarios that are reassessed annually or when market conditions so require.
Additional information is described in Note 32.
Modification of contractual cash flows
When contractual cash flows of a financial asset are renegotiated or otherwise modified and this does not substantially change its terms and conditions, ITAÚ UNIBANCO HOLDING does not derecognize it. However, the gross carrying amount of this financial asset is recalculated as the present value of the renegotiated or changed contractual cash flows, discounted at the original effective interest rate and a modification gain or loss is recognized in profit or loss. Any costs or fees incurred adjust the modified carrying amount and are amortized over the remaining term of the financial asset.
If, on the other hand, the renegotiation or change substantially modifies the terms and conditions of the financial asset, ITAÚ UNIBANCO HOLDING derecognises the original asset and recognizes a new one. Accordingly, the renegotiation date is taken as the initial recognition date of the new asset for expected credit loss calculation purposes, and to determine significant increases in credit risk.
ITAÚ UNIBANCO HOLDING also assesses if the new financial asset may be considered as purchased or originated credit impaired financial asset, particularly when the renegotiation was motivated by the debtor’s financial constraints. Differences between the carrying amount of the original asset and fair value of the new asset are immediately recognized in the Consolidated Statement of Income.
The effects of changes in cash flows of financial assets and other details about methodologies and assumptions adopted by Management to measure the allowance for expected credit loss, including the use of prospective information, are detailed in Note 32.
III - Classification and subsequent measurement of financial liabilities
Financial liabilities are subsequently measured at amortized cost, except for:
 
   
Financial liabilities at fair value through profit
or loss:
this classification applied to derivatives and other financial liabilities designated at fair value through profit or loss to reduce “accounting mismatches”. ITAÚ UNIBANCO HOLDING irrevocably designates financial liabilities at fair value through profit or loss in the initial recognition (fair value option), when the option eliminates or significantly reduces measurement or recognition inconsistencies.
 
   
Loan commitments and financial guarantees:
see details in Note 2.4d VIll.
Modification of financial liabilities
A debt instrument change or substantial terms modification of a financial liability is accounted as a derecognition of the original financial liability and a new one is recognized.
A substantial change to contractual terms occurs when the discounted present value of cash flows under the new terms, including any fees paid/received and discounted using the original effective interest rate, is at least 10% different from discounted present value of the remaining cash flow of the original financial liabilities.
IV – Securities purchased under agreements to resell
ITAÚ UNIBANCO HOLDING purchases financial assets with a resale commitment (resale agreements) and sells securities with a repurchase commitment (repurchase agreement) of financial assets. Resale and repurchase agreements are accounted for under Securities purchased under agreements to resell and Securities sold under repurchase agreements, respectively.
The difference between the sale and repurchase prices is treated as interest and recognized over the life of the agreements using the effective interest rate method.
The financial assets taken as collateral in resale agreements can be used as collateral for repurchase agreements it provided for in the agreements or can be sold.
V - Derivatives
All derivatives are accounted for as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.
The valuation of active hybrid contracts that are subject to IFRS 9 is carried out as a whole, including all embedded characteristics, whereas the accounting is carried out on a joint basis, i.e. each instrument is measured at fair value through profit or loss.
When a contract has a main component outside the scope of IFRS 9, such as a lease agreement receivable or an insurance contract, or even a financial liability, embedded derivatives are treated as separate financial instruments if:
(i) their characteristics and economic risks are not closely related to those of the main component;
(ii) the separate instrument meets the definition of a derivative; and
(iii) the underlying instrument is not booked at fair value through profit or loss.
These embedded derivatives are accounted for separately at fair value, with variations recognized in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities.
ITAÚ UNIBANCO HOLDING will continue applying all the hedge accounting requirements of IAS 39; however, it may adopt the provisions of IFRS 9, if Management so decides.
According to this standard, derivatives may be designated and qualified as hedging instruments for accounting purposes and, the method for recognizing gains or losses of fair value will depending on the nature of the hedged item.
At the beginning of a hedging transaction, ITAÚ UNIBANCO HOLDING documents the relationship between the hedging instrument and the hedged items, as well as its risk management objective and
 
strategy. The hedge is assessed on an ongoing basis to determine if it has been highly effective throughout all periods of the Financial Statements for which it was designated.
IAS 39 describes three hedging strategies: fair value hedge, cash flow hedge, and hedge of net investments in a foreign operation. ITAÚ UNIBANCO HOLDING uses derivatives as hedging instruments under all three hedge strategies, as detailed in Note 7.
Fair value hedge
The following practices are adopted for these operations:
 
  a)
The gain or loss arising from the remeasurement of the hedging instrument at fair value is recognized in income; and
 
  b)
The gain or loss arising from the hedged item, attributable to the effective portion of the hedged risk, is applied to the book value of the hedged item and is also recognized in income.
When a derivative expires or is sold or a hedge no longer meets the hedge accounting criteria or in the event the designation is revoked, the hedge accounting must be prospectively discontinued. In addition, any adjustment to the book value of the hedged item must be amortized in income.
Cash flow hedge
For derivatives that are designated and qualify as hedging instruments in a cash flow hedge, the practices are:
 
  a)
The effective portion of gains or losses on derivatives is recognized directly in Other comprehensive income – Cash flow hedge;
 
  b)
The portion of gain or loss on derivatives that represents the ineffective portion or on hedge components excluded from the assessment of effectiveness is recognized in income.
Amounts originally recorded in Other comprehensive income and subsequently reclassified to Income are recognized in the caption Income of financial assets and Liabilities at fair value through profit or loss at the same time that the corresponding income or expense item of the financial hedge item affects income. For
non-financial
hedge items, the amounts originally recognized in Other comprehensive income are included in the initial cost of the corresponding asset or liability.
When a derivative expires or is sold, when hedge accounting criteria are no longer met or when the entity revokes the hedge accounting designation, any cumulative gain or loss existing in Other comprehensive income will be reclassified to income at the time the expected transaction occurs or is no longer expected to occur.
Hedge of net investments in foreign operations
The hedge of a net investment in a foreign operation, including the hedge of a monetary item that is booked as part of the net investment, is accounted for in a manner similar to a cash flow hedge:
 
  a)
The portion of gain or loss on the hedging instrument determined as effective is recognized in Other comprehensive income;
 
  b)
The ineffective portion is recognized in income.
Gains or losses on the hedging instrument related to the effective portion of the hedge which are recognized in Other comprehensive income are reclassified to income for the period when the foreign operation is partially or totally sold.
VI - Loan operations
ITAÚ UNIBANCO HOLDING classifies a loan as
non-performing
if the payment of the principal or interest has been overdue for 60 days or more. In this case, accrual of interest is no longer recognized.
VII – Premium bonds plans
In Brazil they are regulated by the insurance regulator. These plans do not meet the definition of an insurance contract under IFRS 4, and therefore they are classified as a financial liability at amortized cost under IFRS 9.
Revenue from premium bonds plans is recognized during the period of the contract and measured as the difference between the amount deposited by the customer and the amount that ITAÚ UNIBANCO HOLDING has to reimburse.
VIII – Loan commitments and financial guarantees
ITAÚ UNIBANCO HOLDING recognizes as an obligation in the Consolidated Balance Sheet, on the issue date, the fair value of commitments for loans and financial guarantees. The fair value is generally represented by the fee charged to the customer. This amount is amortized over the term of the instrument and is recognized in the Consolidated Statement of Income under the heading Commissions and Banking Fees.
After issue, if ITAÚ UNIBANCO HOLDING concludes based on the best estimate, that the expected credit loss in relation to the guarantee issued is higher that the fair value less accumulated amortization, this amount is replaced by a provision for loss.
 
 
e)
Investments in associates and joint ventures
I – Associates
Associates are companies in which the investor has a significant influence but does not hold control. Investments in these companies are initially recognized at cost of acquisition and subsequently accounted for using the equity method. Investments in associates and joint ventures include the goodwill identified upon acquisition, net of any cumulative impairment loss.
II – Joint ventures
ITAÚ UNIBANCO HOLDING has joint venture whereby the parties that have joint control of the arrangement have rights to the net assets.
ITAÚ UNIBANCO HOLDING’s share in profits or losses of its associates and joint ventures after acquisition is recognized in the Consolidated statement of income. Its share of the changes in the share in other comprehensive income of corresponding stockholders’ equity of its associates and joint ventures is recognized in its own capital reserves. The cumulative changes after acquisition are adjusted against the carrying amount of the investment. When the ITAÚ UNIBANCO HOLDING’s share of losses in an associates and joint ventures is equal to or more than the value of its interest, including any other receivables, ITAÚ UNIBANCO HOLDING does not recognize additional losses, unless it has incurred any obligations or made payments on behalf of the associates and joint ventures.
Unrealized profits on transactions between ITAÚ UNIBANCO HOLDING and its associates and joint ventures are eliminated to the extent of the interest of ITAÚ UNIBANCO HOLDING. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment of the transferred asset. The accounting policies on associates and joint ventures entities are changed, as necessary, to ensure consistency with the policies adopted by ITAÚ UNIBANCO HOLDING.
If its interest in the associates and joint ventures decreases, but ITAÚ UNIBANCO HOLDING retains significant influence or joint control, only the proportional amount of the previously recognized amounts in Other comprehensive income is reclassified in Income, when appropriate.
 
 
f)
Lease operations (Lessee)
ITAÚ UNIBANCO HOLDING leases mainly real estate properties (underlying assets) to carry out its business activities. The initial recognition occurs when the agreement is signed, in the heading Other Liabilities, which corresponds to the total future payments at present value as a contra entry to the
Right-of-Use
Assets, depreciated under the straight-line method for the lease term and tested semiannually to identify possible impairment losses.
The financial expense corresponding to interest on lease liabilities is recognized in the heading Interest and similar expenses in the Consolidated Statement of Income.
 
g)
Fixed assets
Fixed assets are booked at their acquisition cost less accumulated depreciation, and adjusted for impairment, if applicable. Depreciation is calculated on the straight-line method using rates based on the estimated useful lives of these assets. Such rates and other details are presented in Note 13.
The residual values and useful lives of assets are reviewed and adjusted, if appropriate, at the end of each period.
ITAÚ UNIBANCO HOLDING reviews its assets in order to identify indications of impairment in their recoverable amounts. The recoverable amount of an asset is defined as the higher of its fair value less the cost to sell and its value in use. For the purposes of assessing impairment, assets are grouped at the lowest level for which independent cash flows can be identified (cash-generating units). The assessment may be made at an individual asset level when the fair value less the cost to sell can be reliably determined.
Gains and losses on disposals of fixed assets are recognized in the Consolidated statement of income under Other income or General and administrative expenses.
 
 
h)
Intangible assets
Intangible assets are
non-physical
assets, including software and other assets, and are initially recognized at cost. Intangible assets are recognized when they arise from legal or contractual rights, their costs can be reliably measured, and in the case of intangible assets not arising from separate acquisitions or business combinations, it is probable that future economic benefits may arise from their use. The balance of intangible assets refers to acquired assets or those internally generated.
Intangible assets may have definite or indefinite useful lives. Intangible assets with definite useful lives are amortized using the straight-line method over their estimated useful lives. Intangible assets with indefinite useful lives are not amortized, but periodically tested in order to identify any impairment.
ITAÚ UNIBANCO HOLDING semi-annually assesses its intangible assets in order to identify whether any indications of impairment exist, as well as possible reversal of previous impairment losses. If such indications are found, intangible assets are tested for impairment. The recoverable amount of an asset is defined as the higher of its fair value less the cost to sell and its value in use. For the purposes of assessing impairment, assets are grouped at the lowest level for which independent cash flows can be identified (cash-generating units). The assessment may be made at an individual asset level when the fair value less the cost to sell can be reliably determined.
ITAÚ UNIBANCO HOLDING uses the cost model to measure its intangible assets after its initial recognition.
A breakdown of intangible assets is given in Note 14.
 
 
i)
Assets held for sale
Assets held for sale are recognized in the consolidated balance sheet under the line Other assets when they are actually repossessed or there is intention to sell. These assets are initially recorded at the lower of: (i) the fair value of the asset less the estimated selling expenses, or (ii) the carrying amount of the related asset held for sale.
 
 
j)
Income tax and social contribution
There are two components of the provision for income tax and social contribution: current and deferred.
The current component is approximately the total of taxes to be paid or recovered during the reporting period.
Deferred income tax and social contribution, represented by deferred tax assets and liabilities, is obtained based on the differences between the tax bases of assets and liabilities and the amounts reported in the financial statements at each period.
The income tax and social contribution expense is recognized in the Consolidated statement of income under Income tax and social contribution, except when it refers to items directly recognized in Other
 
comprehensive income, such as: tax on fair value of financial assets measured at fair value through Other comprehensive income, post-employment benefits and tax on cash flow hedges and hedge of net investment in foreign operations. Subsequently, these items are recognized in income upon realization of the gain/loss on the instruments.
Changes in tax legislation and rates are recognized in the Consolidated statement of income in the period in which they are enacted or substantially enacted. Interest and fines are recognized in the Consolidated statement of income under General and administrative expenses.
To determine the proper level of provisions for taxes to be maintained for uncertain tax positions, the approach applied, is that a tax benefit is recognized if it is more likely than not that a position can be sustained, under the assumptions for recognition, detailed in item 2.4 n.
 
 
k)
Insurance contracts and private pensions
Insurance contracts are contracts under which ITAÚ UNIBANCO HOLDING accepts a significant insurance risk of the counterparty, by agreeing to compensate it if a specified uncertain future event adversely affects it. An insurance risk is significant only if the insurance event could cause ITAÚ UNIBANCO HOLDING to pay significant additional benefits in any scenario, other than those that do not have commercial substance. Additional benefits refer to amounts that exceed those that would be payable if no insured event occurred.
Upon its first-time adoption of the IFRS, ITAÚ UNIBANCO HOLDING decided not to change its accounting policies for insurance contracts, which follow the accounting practices generally accepted in Brazil (“BRGAAP”).
Although investment agreements with discretionary participation characteristics are financial instruments, they are treated as insurance contracts, as established by IFRS 4, as well as those transferring a significant financial risk.
Once a contract is classified as an insurance contract, it remains as such until the end of its life, even if the insurance risk is significantly reduced during the period, unless all rights and obligations are extinguished or expire.
Note 27 provides a detailed description of all products classified as insurance contracts.
Private pension plans
Contracts that provide for retirement benefits after an accumulation period (known as PGBL, VGBL and FGB) provide a guarantee, at the commencement date of the contract, of the basis for calculating the retirement benefit (mortality table and minimum interest rates). The contracts specify the annuity rates and, therefore, the insurance risk is transferred to the issuer from the start. These contracts are classified as insurance contracts.
Insurance premiums
Insurance premiums are recognized upon issue of an insurance policy or over the period of the contracts in proportion to the amount of the insurance coverage.
If there is evidence of impairment losses with respect to receivables for insurance premiums, ITAÚ UNIBANCO HOLDING recognizes a provision, sufficient to cover this loss, based on a risk analysis of realization of insurance premiums receivable with installments overdue for over 60 days.
Reinsurance
In the ordinary course of business, ITAÚ UNIBANCO HOLDING reinsures a portion of the risks underwritten, particularly property and casualty risks that exceed the maximum limits of responsibility that determine to be appropriate for each segment and product (after a study which considers size, experience, special features, and the capital necessary to support these limits). These reinsurance agreements allow the recovery of a portion of the losses from the reinsurer, although they do not release the insurer from the main obligation as direct insurer of the risks covered by the reinsurance.
ITAÚ UNIBANCO HOLDING mainly holds
non-proportional
contracts, which transfer part of responsibility to the reinsurance company for losses that will materialize after a certain level of claims in the portfolio.
 
Reinsurance premiums of these contracts are accounted for under Other Assets, over the life of each contract.
If there is any evidence of impairment loss, ITAÚ UNIBANCO HOLDING recognizes a provision when the default period exceeds 180 days from the registration of the request for fund of claims paid.
Acquisition costs
Acquisition costs include direct and indirect costs related to the origination of insurance. These costs are recorded directly in result as incurred, except for deferred acquisition costs (commissions paid for brokerage services, agency and prospecting efforts), which are recorded proportionally to the recognition of premium revenues, i.e. over the term corresponding to the insurance contract.
Insurance Contract Liabilities
Reserves for claims are established based on past experience, claims in process of payment, estimated amounts of claims incurred but not yet reported, and other factors relevant to the required reserve levels.
Liability Adequacy Test
ITAÚ UNIBANCO HOLDING tests liability adequacy by adopting current actuarial assumptions for future cash flows of all insurance contracts in force at the balance sheet date.
Should the analysis show insufficiency, any shortfall identified will immediately be accounted for in income for the period.
The assumptions used to conduct the liability adequacy test are detailed in Note 27.
 
 
l)
Post-employments benefits
ITAÚ UNIBANCO HOLDING sponsors Defined Benefit Plans and Defined Contribution Plans, which are accounted for in accordance with IAS 19 – Benefits to Employees.
ITAÚ UNIBANCO HOLDING is required to make contributions to government social security and labor indemnity plans, in Brazil and in other countries where it operates.
Pension plans - Defined benefit plans
The liability or asset, as the case may be, is recognized in the Consolidated Balance Sheet with respect to a defined benefit plan corresponds to the present value of defined benefit obligations at the balance sheet date less the fair value of plan assets. The defined benefit obligations are calculated annually using the projected unit credit method.
Pension plans - Defined contribution
For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING, through pension plan funds, are recognized as liabilities, with a counter-entry to expenses, when due. If contributions made exceed the liability for a service provided, it will be accounted for as an asset recognized at fair value, and any adjustments are recognized in Stockholders’ equity, under Other comprehensive income, in the period when they occur.
Other post-employment benefit obligations
Like defined benefit pension plans, these obligations are assessed annually by independent, qualified actuaries, and costs expected from these benefits are accrued over the period of employment. Gains and losses arising from changes in practices and variations in actuarial assumptions are recognized in Stockholders’ equity, under Other comprehensive income, in the period in which they occur.
 
 
m)
Share-based payments
Share-based payments are booked for the value of equity instruments granted based on their fair value at the grant date. This cost is recognized during the vesting period of the instruments right.
The total amount to be expensed is determined by reference to the fair value of the equity instruments excluding the impact of any service commissions and fees and
non-market
performance vesting conditions (in particular when an employee remains with the company for specific period of time).
 
 
n)
Provisions, contingent assets and contingent liabilities
Contingent assets and liabilities are possible rights and potential obligations arising from past events for which realization depends on uncertain future events.
Contingent assets are not recognized in the Consolidated Financial Statements, except when the Management of ITAÚ UNIBANCO HOLDING considers that realization is practically certain. In general they correspond to lawsuits with favorable outcomes in final and unappealable judgments and to the withdrawal of lawsuits as a result of a settlement payment received or an agreement for
set-off
against an existing liability.
These contingencies are evaluated based on Management’s best estimates, and are classified as:
 
   
Probable:
in which liabilities are recognized in the consolidated balance sheet under Provisions;
 
   
Possible:
which are disclosed in the Consolidated Financial Statements, but no provision is recorded;
 
   
Remote:
which require neither a provision nor disclosure.
The amount of deposits in guarantee is adjusted in accordance with current legislation.
 
 
o)
Capital
Common and preferred shares, which for accounting purposes are equivalent to common shares but without voting rights are classified in Stockholders’ equity. The additional costs directly attributable to the issue of new shares are included in Stockholders’ equity as a deduction from the proceeds, net of taxes.
 
 
p)
Treasury shares
Common and preferred shares repurchased are recorded in Stockholders’ equity under Treasury shares at their average purchase price.
Shares that are subsequently sold, such as those sold to grantees under our share-based payment scheme, are recorded as a reduction in treasury shares, measured at the average price of treasury stock held at that date.
The difference between the sale price and the average price of the treasury shares is recorded as a reduction or increase in Capital Reserves. The cancellation of treasury shares is recorded as a reduction in Treasury shares against Capital Reserves, at the average price of treasury shares at the cancellation date.
 
 
q)
Dividends and interest on capital
Minimum dividend amounts established in the bylaws are recorded as liabilities at the end of each year. Any other amount above the mandatory minimum dividend is accounted for as a liability when approved by of the Board of Directors.
Interest on capital is treated for accounting purposes as a dividend, and it is presented as a reduction of stockholders’ equity in the consolidated financial statements.
 
Dividends have been and continue to be calculated and paid on the basis of the financial statements prepared under Brazilian accounting standards and regulations for financial institutions, not these Consolidated financial statements prepared according to the IFRS.
Dividends and interest on capital are presented in Note 19.
 
 
r)
Earnings per share
ITAÚ UNIBANCO HOLDING grants stock options whose dilutive effect is reflected in diluted earnings per share, with the application of the “treasury stock method“. Whereby earnings per share are calculated as if all the stock options had been exercised and the proceeds used to purchase shares of ITAÚ UNIBANCO HOLDING.
Earnings per share are presented in Note 25.
 
 
s)
Segment information
Segment information disclosed is consistent with the internal reports prepared for the Executive Committee which makes the operational decisions ITAÚ UNIBANCO HOLDING.
ITAÚ UNIBANCO HOLDING has three reportable segments: (i) Retail Banking (ii) Wholesale Banking and (iii) Market + Corporation.
Segment information is presented in Note 30.
 
 
t)
Commissions and Banking Fees
Commissions and Banking Fees is recognized when ITAÚ UNIBANCO HOLDING provides or offers services to customers, in an amount that reflects the consideration ITAÚ UNIBANCO HOLDING expects to collect in exchange for those services. A five-step model is applied to account for revenues: i) identification of the contract with a customer; ii) identification of the performance obligations in the contract; iii) determination of the transaction price; iv) allocation of the transaction price to the performance obligations in the contract; and v) revenue recognition, when performance obligations agreed upon in agreements with clients are met. Incremental costs and costs to fulfill agreements with clients are recognized as an expense as incurred.
The main services provided by ITAÚ UNIBANCO HOLDING are:
