Notes to the Consolidated Interim Financial Statements June 30, 2023

These consolidated financial statements cover the following periods:

The consolidated interim financial statements of Sociedad Química y Minera de Chile S.A. and its subsidiaries were prepared in accordance with la IAS 34 “Interim Financial Reporting”.

The consolidated interim financial statements should be read in conjunction with the annual financial statements as of December 31, 2022.

The accounting principles and criteria used in these interim financial statements were consistently applied throughout both periods and to the annual financial statements as of December 31, 2022. There have been no changes in the methods used to calculate accounting estimates during the periods reported.

IFRS establish certain alternatives for their application, those applied by the Company are detailed in this Note and Note 3.

Notes to the Consolidated Interim Financial Statements June 30, 2023

The consolidated financial statements have been prepared on the historical cost basis except for the following:

New accounting pronouncements

Management determined that the adoption of the aforementioned standards, amendments and interpretations did not significantly impact the company’s consolidated financial statements.

Notes to the Consolidated Interim Financial Statements June 30, 2023

Management believes that the adoption of the above standards, amendments and interpretations will not have a significant impact on the Company’s financial statements.

Notes to the Consolidated Interim Financial Statements June 30, 2023

The Company established control as the basis of consolidation of its financial statements. The Company controls a subsidiary when it is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary.

The consolidation of a subsidiary starts when the Group controls it and it is no longer included in the consolidation when control is lost.

Subsidiaries are consolidated through the line by line method, adding items that represent assets, liabilities, income and expenses with a similar content, and eliminating operations between companies within the SQM Group.

Results for dependent companies acquired or disposed of during the period are included in the consolidated accounts from the date on which control is transferred to the SQM Group or until the date when this control ends, as relevant.

To account for an acquisition of a business, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, equity securities issued, and incurred or assumed liabilities at the date of exchange. Assets, liabilities and contingencies identifiable assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure the non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquire.

The details of the consolidated companies can be found in Note 7.

Investments in joint arrangements are classified as joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement.

The Company recognizes its direct right to the assets, liabilities, income and expenses of the joint arrangement.

Interests in companies over which joint control is exercised (joint ventures) or where an entity has significant influence (associates) are recognized using the equity accounting method. Significant influence is presumed when the investor owns over 20% of the investee’s share capital. The investment is recognized using this method in the statement of financial position at cost plus changes subsequent to acquisition and includes the proportional share of the associate’s equity. For these purposes, the percentage interest in the associate is used. The associated acquired goodwill is included in the investee’s book value and is not amortized. The debit or credit to the income statement reflects the proportional share of the profit or loss of the associate.

Unrealized gains from transactions with joint ventures or associates are eliminated in accordance with the Company’s percentage interest in such entities. Any unrealized losses are also eliminated, unless that transaction provides evidence that the transferred asset is impaired.

Changes in associate’s or joint ventures equity are recognized proportionally with a charge or credit to “Other Reserves” and are classified according to their origin. The reporting dates of the associate or joint ventures, the Company and related policies are similar for equivalent transactions and events in similar circumstances. In the event that significant influence is lost, or the investment is sold, or held for sale, the equity method is suspended, not recognizing the proportional share of the gain or loss. If the resulting value under the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless there is a commitment by the Company to restore the capital position of the Company, in which case the related risk provision and expense are recorded.

Notes to the Consolidated Interim Financial Statements June 30, 2023

Dividends received by these companies are recorded by reducing the value of the investment and are shown in cash flows from operating activities, and the proportional share of the gain or loss recognized in accordance with the equity method is included in the consolidated income statement under “Share of Gains (Losses) of Associates and Joint Ventures Accounted for Using the Equity Method’’.

Notes to the Consolidated Interim Financial Statements June 30, 2023

In the consolidated statement of financial position, balances are classified in consideration of their maturity dates; i.e., those maturing within a period equal to or less than 12 months are classified as current counted from the closing date of the consolidated financial statements and those with maturity dates exceeding the aforementioned period are classified as non-current.

The exception to the foregoing relates to deferred taxes, which are classified as non-current, regardless of the maturity they have.

The Company’s consolidated financial statements are presented in United States dollars, without decimal places, which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates. Consequently, the term foreign currency is defined as any currency other than the U.S. dollar.

The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows:

In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in shareholder’s equity (“foreign currency translation reserve”). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale.

Notes to the Consolidated Interim Financial Statements June 30, 2023

The main exchange rates and UF used to translate monetary assets and liabilities, expressed in foreign currency at the end and average of each period in respect to U.S. dollars, are as follows:

(*) US$ per UF

(b)         Transactions and balances

The Company’s non-monetary transactions in currencies other than the functional currency (Dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income until disposal of the investment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income.

Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined.

Notes to the Consolidated Interim Financial Statements June 30, 2023

Cash equivalents correspond to highly liquid short-term investments that are easily convertible into known amounts of cash and subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument.

For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above.

The statement of cash flows present cash transactions performed during the period, determined using the direct method.

Management determines the classification of its financial assets at fair value (either through other comprehensive income, or through profit or loss), and at amortized cost. The classification depends on the business model of the entity to manage the financial assets and the contractual terms of the cash flows.

The initial value of the Company’s financial assets valued at fair value through comprehensive income includes the transaction costs that are directly attributable to acquiring that financial asset on the date the Company commits to acquiring it, whereas the transaction costs for financial assets valued at fair value through profit or loss are expensed. The initial value of trade and other receivables that do not include a significant financial component is their transaction price.

After initial recognition, the Company measures its financial assets according to the Company’s business model for managing its financial assets and the contractual terms of its cash flows:

Notes to the Consolidated Interim Financial Statements June 30, 2023

The Company evaluates expected credit losses associated with its debt instruments carried at amortized cost. The impairment method used depends on whether there has been a significant increase in credit risk.

The Company assumes that the credit risk of a financial asset has increased significantly when it is more than 30 days past due. It is in default when the financial asset is more than 90 days past due and an individual analysis has concluded that it has a negative credit impairment.

The Company assesses the credit impairment of its receivables as of each reporting date. A financial asset has credit impairment when one or more events have a negative impact on the expected cash flows from it. Evidence of credit impairment for a debtor is as follows:

The Company applies the simplified approach to measure expected credit losses using the lifetime expected loss on all trade receivables. Expected credit losses are measured by grouping receivables by their shared credit risk characteristics and days overdue.

The Company has concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for these assets. Expected loss rates are based on sales payment profiles and historical credit losses within this period. Historical loss rates are adjusted to reflect current expectations and information regarding macroeconomic factors that affect the ability of customers to meet their commitments. Impairment losses from receivables and contract assets are shown as net impairment losses in the line “Impairment of financial assets and reversal of impairment losses,” see Note 22.7. Any subsequent recoveries of financial assets previously charged off are credited to the same line.

The gross value of a financial asset is charged off to the income statement when the Company has no reasonable expectation of recovering all or a portion of it, following an individual analysis prepared by management.

Management accounts for its financial liabilities at amortized cost.

Upon initial recognition, the Company measures its financial liabilities by their fair value less the transaction costs that are directly attributable to the acquisition of the financial liability. The Company subsequently measures its financial liabilities at amortized cost.

Financial liabilities measured at amortized cost are commercial accounts payable and other accounts payable and other financial liabilities.

Amortized cost is based using the effective interest rate method. Amortized cost is calculated by considering any premium or discount on the acquisition and includes transaction costs that are an integral part of the effective interest rate.

Notes to the Consolidated Interim Financial Statements June 30, 2023

The fair value of financial assets and liabilities is estimated using the following information. Although the data represent Management’s best estimates, it is subjective and involves significant estimates regarding current economic conditions, market conditions and risk characteristics.

Methodologies and assumptions used depend on the risk terms and characteristics of instruments and include the following as a summary:

Fair value estimation

Financial assets and liabilities measured at fair value consist of forwards hedging the mismatch in the balance sheet and cash flows, options hedging the mismatch in the balance sheet and cross currency swaps to hedge bonds issued in local currency (Peso/UF).

The fair value of the Company’s assets and liabilities recognized by cross currency swaps contracts is calculated as the difference between the present value of discounted cash flows of the asset (Peso/UF) and liability (Dollar) parts of the derivative. In the case of the IRSW, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Financial options: the value recognized is calculated using the Black-Scholes method.

In the case of CCS, the entry data used for the valuation models are UF, Peso, Dollar and basis swap rates. In the case of fair value calculations for interest rate swaps, the Forward Rate Agreement rate and ICVS 23 Curve (Bloomberg: cash/deposits rates, futures, swaps). In the case of forwards, the forwards curve for the currency in question is used. Finally, for options, the spot price, risk-free rate and volatility of exchange rate are used, all in accordance with the currencies used in each valuation. The financial information used as entry data for the Company’s valuation models is obtained from Bloomberg, the well-known financial software company. Conversely, the fair value provided by the counterparties of derivatives contracts is used only as a control and not for valuation.

The effects on profit or loss of movements in these amounts is recognized in the caption finance costs, foreign currency translation gain (loss) or cash flow hedge reserve in the statement of comprehensive income, depending on each particular case.

Estimate of fair value for disclosure purposes

Notes to the Consolidated Interim Financial Statements June 30, 2023

When the Company changes its business model for managing financial assets, it will reclassify all its financial assets affected by the new business model. Financial liabilities cannot be reclassified.

The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained.

The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished from the principle responsibility contained in the liability.

The financial instruments derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows:

At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations.

The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items.

The fair value of derivative instruments used for hedging purposes is shown in Note 13.3.

Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss.

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate.

Notes to the Consolidated Interim Financial Statements June 30, 2023

b)     Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is initially recognized with a debit or credit to other comprehensive income, while any ineffective portion is immediately recognized to income, as appropriate, depending on the nature of the hedged risk. The amounts accumulated in other comprehensive income are carried over to results when the hedged items are settled or when these have an impact on income.

When a hedging instrument no longer meets the criteria for hedge accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs.

When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in other comprehensive income are immediately reclassified to profit or loss.

Derivative financial instruments not considered as hedges are recognized at fair value with the effect in the profit of the year. The Company has derivative financial instruments to hedge foreign currency risk exposure.

The Company continually evaluates the existence of embedded derivatives in both its contracts and in its financial instruments. As of June 30, 2023, and December 31, 2022, the Company does not have any embedded derivatives.

Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis independent of payment date. These are recognized under other non-financial assets current.

The Company recognizes right-of-use assets on the initial lease date (i.e., the date on which the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, adjusted by any new measurement of the lease liability. The cost of right-of-use assets includes the amount of recognized lease liabilities, direct initial costs incurred and lease payments made on the start date or sooner, less the lease incentives received. Unless the Company is reasonably sure it will take ownership of the leased asset at the end of the lease period, the assets recognized through right-of-use are depreciated in a straight line during the shortest period of their estimated useful life and lease period. Right-of-use assets are subject to impairment.

On the lease start date, the Company recognizes lease liabilities measured at present value of lease payments that will be made during the lease period. Lease payments include fixed payments (including payments that are essentially fixed), less incentives for lease receivables, variable lease payments that are dependent on an index or rate and amounts that are expected to be paid as guaranteed residual value. Lease payments also include the exercise price of a purchase option if the Company is reasonably sure it will exercise this and penalty payments for terminating a lease, if the lease period reflects that the Company will exercise the option to terminate. Variable lease payments that are not dependent on an index or rate are recognized as expenses in the period that produces the event or condition that triggers payment.

When calculating the present value of lease payments, the Company uses the incremental borrowing rate on the initial lease date if the interest rate implicit in the lease cannot be determined easily. After the start date, the lease liability balance will increase to reflect the accumulation of interest and will diminish as lease payments are made. Furthermore, the book value of lease liabilities is remeasured in the event of an amendment, a change in the lease period, a change in the fixed lease payments in substance or a change in the assessment to buy the underlying asset.

Notes to the Consolidated Interim Financial Statements June 30, 2023

Payments made that affect lease liabilities are presented as part of the financing activities in the cash flow statement.

The Company applies the short-term lease recognition exemption to leases with a lease term of 12 months or less starting on the start date and that don’t have a purchase option. It also applies the low-value asset lease recognition exemptions to leases less than the limit specified in the respective accounting standard. Lease payments in short-term leases and low-value asset leases are recognized as lineal expenses during the lease term.

The Company determines the lease term as the non-cancellable period of the lease, together with periods covered by an option to extend the lease if it is reasonably certain that this will be exercised, or any period covered by an option to terminate the lease, if it is reasonably certain that this will not be exercised.

The Company has the option, under some of its leases, to lease assets for additional terms. The Company applies its judgment when assessing whether it is reasonably certain that it will exercise the option to renovate. In other words, it considers all the relevant factors that create an economic incentive for it to exercise the option to renovate. After the start date, the Company reevaluates the lease term if there is a significant event or change in the circumstances that are under its control and affect its capacity to exercise (or not exercise) the option to renovate.

The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage. In determining production costs for own products, the company includes the costs of labor, raw materials, materials and supplies used in production, depreciation and maintenance of the goods that participate in the production process, the costs of product movement necessary to maintain stock on location and in the condition in which they are found, and also includes the indirect costs of each task such as laboratories, process and planning areas, and personnel expenses related to production, among others.

For finished and in-process products, the company has four types of provisions, which are reviewed quarterly:

Notes to the Consolidated Interim Financial Statements June 30, 2023

Inventories of raw materials, materials and supplies for production are recorded at acquisition cost. Cyclical inventories are performed in warehouses, as well as general inventories every three years. Differences are recognized at the moment they are detected. The company has a provision based on quarterly calculations from percentages associated with each type of material (classification by warehouse and rotation), these percentages use the lower value resulting from deterioration or obsolescence as well as potential losses. This provision is reviewed at least annually, and considers the historical profit and loss obtained in the inventory processes.

Non-controlling interests are recorded in the consolidated statement of financial position within equity but separate from equity attributable to the owners of the Parent.

Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. The maturity conditions vary according to the originating transaction.

Property, plant and equipment are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced.

In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable:

Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets.

Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date.

Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred.

The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements.

Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income or (loss) in the period and calculated as the difference between the asset’s sales value and its net carrying value.

Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred.

The cost of interest is recognized by applying an average or average weighted interest rate for all financing costs incurred by the Company to the final monthly balances for works underway and complies with the requirements of the required standard.

Financing costs are not activated for periods that exceed the normal term for acquisition, construction or installation of the property; such is the case for delays, interruptions or temporary suspension of the project due to technical, financial or other problems that make it impossible to leave the property in usable conditions.

Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets and depreciated over their expected useful lives. Useful lives are reviewed on an annual basis.

Fixed assets located in the Salar de Atacama consider useful life to be the lesser value between the technical useful life and the years remaining until 2030.

In the case of certain mobile equipment, depreciation is performed depending on the hours of operation.

The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below:

Goodwill acquired represents the excess in acquisition cost on the fair value of the Company’s ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in the line item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold.

This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose.

Intangible assets other than goodwill mainly relate to water rights, costs for rights of way for electricity lines, software and licensing costs, the development of computer software and mining property and concession rights.

Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into:

i) Finite rights with amortization using the straight-line method, and

ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company, which are subject to an annual impairment assessment.

As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. Amounts paid are capitalized at the date of the agreement and amortized in the statement of income, according to the life of the right of way.

Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives. The useful lives of IT programs are defined by their contracts or rights.

Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received.

The costs of development for IT programs are recognized as assets are amortized over their estimated useful lives.

The Company holds mining property and concession rights from the Chilean and Western Australian Governments. Property rights from the State of Chile are usually obtained at no initial cost (other than the payment of mining patents and minor recording expenses) and once the rights on these concessions have been obtained, they are retained by the Company while annual patents are paid. Such patents, which are paid annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties that are not from the Chilean Government are recorded at acquisition cost within intangible assets.

The finite useful life of mining properties is calculated using the productive unit method, except for the mining properties owned by Corfo, which have been leased to the Company and grant it the right to exclusively exploit them until December 31, 2030.

Minimum and maximum amortization lives or rates of intangible assets:

Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred.

The Company holds mining concessions for exploration and exploitation of ore, the Company gives the following treatment to expenses associated:

Once the rights have been obtained, the Company records the disbursements directly associated with the exploration and evaluation of the deposit in execution as property, plant and equipment (construction in progress) at its cost. These disbursements include the following items: geological surveys, drilling, borehole extraction and sampling, activities related to the technical assessment and commercial viability of the extraction, and in general, any disbursement directly related to specific projects where the objective is to find ore resources. If the technical studies determine that the ore grade is not economically viable, the asset is directly charged to profit and loss. If determined otherwise, the asset described above is associated with the extractable ore tonnage which is amortized as it is used.

(a) Limestone and metallic exploration

These assets are included in Other Non-Current Non-Financial Assets, and the portion related to the area to be exploited in the year is reclassified to Inventories, if applicable. Costs related to metal exploration are charged to profit or loss in the period in which they are recognized if the project assessed doesn’t qualify as advanced exploration otherwise, these are amortized during the development stage.

(b) Exploration and evaluation at the Mt. Holland Project

Mount Holland exploration and evaluation expenditure is included in Property, plant and equipment, specifically in Construction in Progress.

Assets subject to depreciation and amortization are also subject to impairment testing, provided that an event or change in the circumstances indicates that the amounts in the accounting records may not be recoverable, an impairment loss is recognized for the excess of the book value of the asset over its recoverable amount.

For assets other than goodwill, the Group annually assesses whether there is any indication that a previously recognized impairment loss may no longer exist or may have decreased. Should such indications exist, the recoverable amount is estimated.

The recoverable amount of an asset is the higher between the fair value of an asset or cash generating unit less costs of sales and its value in use, and is determined for an individual asset unless the asset does not generate any cash inflows that are clearly independent from other assets or groups of assets.

In evaluating value in use, estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessment, the value of money over time and the specific asset risks.

Impairment losses from continuing operations are recognized with a debit to profit or loss in the categories of expenses associated with the impaired asset function.

For assets other than goodwill, a previously recognized impairment loss is only reversed if there have been changes in the estimates used to determine the asset’s recoverable amount since the last time an impairment loss was recognized. If this is the case, the carrying value of the asset is increased to its recoverable amount. This increased amount cannot exceed the carrying value that would have been determined, net of depreciation, if an asset impairment loss had not been recognized in prior years. This reversal is recognized with a credit to profit or loss.

Assets with indefinite lives are assessed for impairment annually.

As required by Chilean law and regulations, the dividend policy is decided upon from time to time by the Board of Directors and is announced at the Annual Ordinary Shareholders’ Meeting, which is generally held in April of each year. Shareholder’s approval of the dividend policy is not required. However, each year the Board must submit the declaration of the final dividend or dividends in respect of the preceding year, consistent with the then-established dividend policy, to the Annual Ordinary Shareholders’ Meeting for approval. As required by the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued shares, the Company must distribute a cash dividend in an amount equal to at least 30% of our consolidated net income for that year (determined in accordance with CMF regulations), unless and to the extent there is a deficit in retained earnings. (See Note 20.5).

The basic earnings per share amounts are calculated by dividing the profit for the year attributable to the ordinary owners of the parent by the weighted average number of ordinary shares outstanding during the year.
