    Note 3    Significant accounting policies
     
    3.1
    Classification of balances as current and non-current
     
    In the attached consolidated statement of financial position, balances are classified in consideration of their recovery (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.
     
    3.2
    Functional and presentation currency
     
    The Company’s consolidated financial statements are presented in United States dollars (“U.S. dollars” or “US$”), 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 consolidated financial statements are presented in thousands of United States dollars without decimals.
     
    3.3
    Foreign currency translation
     
    (a)       Group entities:
     
    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:
     
    -
    Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date.
     
    -
    Revenues and expenses of each profit or loss account are converted at monthly average exchange rates.
     
    -
    All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves.
       
    In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in equity (other reserves). 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.
     
    The main exchange rates and the adjustment unit used to translate monetary assets and liabilities, expressed in foreign currency at the end of each period in respect to U.S. dollars, are as follows:

    (b)       Transactions and balances
     
    Non-monetary transactions in currencies other than the functional currency (U.S. 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 on the divestment, 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 that are 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.
     
    3.4
    Subsidiaries
     
    SQM S.A. uses the level of control it has in subsidiaries as a basis to determine their share in the consolidated financial statements. This control consists of the Company’s ability to exercise power in the subsidiary, exposure, or right, to variable performance from its share in the investee and the ability to use its power on the investee to have an influence on the amount of the investor’s performance.
     
    The Company prepares the consolidated financial statements using consistent accounting policies for the entire Group. The consolidation of a subsidiary commences when the Company has control over the subsidiary and stops when control ceases.
     
    3.5
    Consolidated statement of cash flows
     
    Cash equivalents correspond to highly-liquid short-term investments that are easily convertible into known amounts of cash. They are 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 includes movements in cash performed during the year, determined using the direct method.
     
    3.6
    Financial assets
     
    Management determines the classification of its financial assets at the time of initial recognition, on the basis of the business model for the management of financial assets and the characteristics of contractual cash flows from the financial assets. In accordance with IAS 39, financial assets are measured initially at fair value plus transaction costs that may have been incurred and are directly attributable to the acquisition of the financial asset. Subsequently, financial assets are measured at amortized cost or fair value.
     
    The Company assesses, at each reporting date, whether there is objective evidence that an asset or group of assets is impaired. An asset or group of financial assets is impaired if and only if there is evidence of impairment as a result of one or more events occurring after the initial recognition of the asset or group of assets. For the recognition of impairment, the loss event has to have an impact on the estimate of future cash flows from the asset or groups of financial assets.
     
    3.7
    Financial liabilities
     
    Management determines the classification of its financial liabilities at the time of initial recognition. As established in IAS 39, financial liabilities at the time of initial recognition are measured at fair value, less transaction costs that may have been incurred and are directly attributable to the issue of the financial liability. Subsequently, these are measured at amortized cost using the effective interest method. Financial liabilities that have been initially recognized at fair value through profit or loss will be measured subsequently at fair value.
     
    3.8
    Financial instruments at fair value through profit or loss
     
    Management will irrevocably determine, at the time of initial recognition, the designation of a financial instrument at fair value through profit or loss. By doing so, this eliminates and/or significantly reduces the measurement or recognition inconsistency that would otherwise have arisen from the measurement of assets or liabilities or from the recognition of gains and losses from them on different bases.
     
    3.9
    Financial instrument offsetting
     
    The Company offsets an asset and liability if and only if it presently has a legally enforceable right of setting off the amounts recognized and has the intent of settling for the net amount of realizing the asset and settling the liability simultaneously.
     
    3.10
    Reclassification of financial instruments
     
    At such time when the Company changes its business model for managing financial assets, it will reclassify those financial assets affected by the new business model.
     
    Financial liabilities could not be reclassified.
     
    3.11
    Derivative and hedging 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:
     
    a)
    Fair value hedge of assets and liabilities recognized (fair value hedges);
     
    b)
    Hedging of a single risk associated with an asset or liability recognized or a highly probable forecast transaction (cash flow hedge).
     
    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 10.3 (hedging assets and liabilities). Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the entry is less than 12 months.
     
    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.
     
    a)
    Fair value hedge
     
    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.
     
    b)
    Cash flow hedges
     
    The effective portion of gains or losses from the hedge instrument is initially recognized with a debit or credit to other comprehensive income, whereas any ineffective portion is immediately recognized with a debit or credit to profit or loss, as applicable.
     
    Amounts taken to equity are transferred to profit or loss when the hedged transaction affects profit or loss, as when the hedged interest income or expense is recognized when a projected sale occurs. When the hedged entry is the cost of a non-financial asset or liability, amounts taken to other reserves are transferred to the initial carrying value of the non-financial asset or liability.
     
    If the expected firm transaction or commitment is no longer expected to occur, the amounts previously recognized in equity are transferred to profit or loss. If a hedge instrument expires, is sold, finished, or exercised without any replacement, or if a rollover is performed or if its designation as hedging is revoked, the amounts previously recognized in other reserves are maintained in equity until the expected firm transaction or commitment occurs.
     
    3.12
    Available for sale financial assets
     
    Available for sale financial assets are non-derivative financial assets, which have been designated as available for sale and are not classified in any of the previous categories of financial instruments. Available for sale financial instruments are initially recognized at fair value plus any directly attributable transaction costs.
     
    Subsequent to initial recognition, they are recognized at fair value and changes other than impairment losses are recognized in other comprehensive income and presented in equity in the fair value reserve. If an investment is derecognized, the accumulated gain or loss is reclassified to profit or loss.
     
    3.13
    Derecognition of financial instruments
     
    In accordance with IAS 39, 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.
     
    3.14
    Derivative financial instruments
     
    The Company maintains derivative financial instruments to hedge its exposure to foreign currencies. Derivative financial instruments are recognized initially at fair value; attributable transact ion costs are recognized when incurred. Subsequent to initial recognition, any changes in the fair value of such derivatives are recognized in profit or loss as part of gains and losses.
     
    The Company permanently assesses the existence of embedded derivatives, both in its contracts and financial instruments. As of December 31, 2017, and December 31, 2016, there were no embedded derivatives.
     
    3.15
    Fair value initial measurements
     
    From the initial recognition, the Company measures its assets and liabilities at fair value plus or minus transaction costs incurred that are directly attributable to the acquisition of a financial asset or issuance of a financial liability.
     
    3.16       Deferred acquisition costs from insurance contracts
     
    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, and are recognized under other non-financial assets.
     
    (a)     Lease  - Finance lease
     
    Leases are classified as finance leases when the Company holds substantially all the risks and rewards derived from the ownership of the asset. Finance leases are capitalized at the beginning of the lease, at the lower of the fair value of the leased asset or the present value of minimum lease payments.
     
    Each lease payment is distributed between the liability and the interest expenses to obtain ongoing interest on the pending balance of debt. The respective lease obligations, net of interest expense, are included in other non-current liabilities. The interest element of finance cost is debited in the consolidated statement of income during the lease period so that a regular ongoing interest rate is obtained on the remaining balance of the liability for each year.
     
    (b)      Lease  – Operating lease
     
    Leases in which the lesser maintains a significant part of the risks and rewards derived from the ownership are classified as operating leases. Operating lease payments (net of any incentive received from the lesser) are debited to the statement of income or capitalized (as applicable) on a straight-line basis over the lease period.
     
    3.17
    Trade and other receivables
     
    Trade and other receivables relate to non-derivative financial assets with fixed and determinable payments and are not quoted in any active market. These arise from sales operations involving the products and/or services, of which the Company commercializes directly to its customers.
     
    These assets are initially recognized at their fair value and subsequently at amortized cost according to the effective interest rate method, less a provision for impairment loss. An allowance for impairment loss is established for trade receivables when there is objective evidence that the Company will not be able to collect all the amounts which are owed to it, according to the original terms of receivables.
     
    Implicit interest in installment sales is recognized as interest income when interest is accrued over the term of the operation.
     
    3.18
    Inventory measurement
     
    The Company measures inventories at the lower of production cost and net realizable value. The cost price of finished products and work in progress includes the direct cost of materials and, when applicable, labor costs, the depreciation of goods that are involved in the production process, the indirect costs incurred in transforming raw materials into finished products, and general expenses incurred in carrying inventories to their current location and conditions. The method used to determine the cost of inventories is the weighted average monthly cost and the average cost of warehouse storage.
     
    Commercial discounts, rebates obtained, and other similar entries are deducted when determining the acquisition price.
     
    The net realizable value represents the estimated selling price, less all the estimated costs of completion and the estimated costs necessary to make the sale.
     
    The Company conducts an evaluation of the net realizable value of inventories at the end of each year, recording a debit to profit or loss when the inventory costs exceed the realizable value.   This estimate is made for all the finished and intermediate products in the Company’s inventory. The valuation of obsolete, impaired or slow-moving products relates to their estimated net realizable value.
     
    The provisions for uncertainties in the technical specifications for the Company’s stocks of finished goods and work in progress have been made based on a technical study which covers the different variables that affect products in stock (such as density and humidity). This study is updated periodically to include new measurement technologies  and the results from previous financial periods.
     
    Inventories of raw materials, supplies, materials and parts are recorded at the lower of acquisition cost or market value.  The acquisition cost is calculated according to the average acquisition price method. Nonetheless, an estimate is made for each financial period of the potential lower value relating to the proportion of inventory that consists of obsolete, defective or slow-moving materials. This provision reduces the value of the Company’s raw materials, supplies, materials and parts.
     
    3.19       Investments in associates and joint ventures
     
    Interests in companies over which joint control is exercised (joint venture) or where an entity has a significant influence (associates) are recognized using the equity method of accounting. Significant influence is presumed to exist when interest greater than 20% is held in the capital of an investee.
     
    Under this method, the investment is recognized in the statement of financial position at cost plus changes, subsequent to the acquisition, and considering the proportional share in the equity of the associate. For such purposes, the interest percentage in the ownership of the associate is used. The associated goodwill acquired is included in the carrying amount of the investee and is not amortized. The debit or credit to profit or loss reflects the proportional share in the profit or loss of the associate.
     
    Unrealized gains for transactions with affiliates or associates are eliminated according to the Company’s interest percentage in such entities. Unrealized losses are also eliminated, except if the transaction provides evidence of impairment loss of the transferred asset.
     
    Changes in the equity of associates are recognized on a proportional basis with a charge or credit to “Other reserves” and classified according to their origin.
     
    Reporting dates of the associate, the Company and related policies are similar for equivalent transactions and events under similar circumstances.
     
    In the event that the significant influence is lost or the investment is sold or is held as available for sale, the equity method is discontinued, suspending the recognition of the proportional share of profit or loss.
     
    If the resulting amount according to the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless a commitment exists by the Company to reinstate the Company’s equity position, in which case the related provision for risks and expenses is recorded.
     
    Dividends received by these companies are recorded by reducing the equity value, and the proportional share of profit or loss recognized according to the equity share are included in the consolidated profit or loss accounts in the caption “Equity share of profit (loss) of associates and joint ventures that are accounted for using the equity method of accounting”.
     
    3.20
    Transactions with non-controlling interests
     
    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.
     
    3.21
    Related party transactions
     
    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. These transactions have been eliminated in consolidation. The expiration conditions vary according to the originating transaction.
     
    3.22
    Property, plant and equipment
     
    The assets tangible property, plant and equipment assets 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:
     
    1.       Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company.
     
    2.       The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the obligation.
     
    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 full 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.

    3.23    Depreciation of property, plant and equipment
     
    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. Useful lives are reviewed on an annual basis.
     
    In the case of mobile equipment, depreciation is performed depending on the hours of operation

    Goodwill
     
    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 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.
     
    3.25
    Intangible assets other than goodwill
     
    Intangible assets mainly relate to water rights, rights issues, electric line easement expenses and software license and development expenses.
     
    (a)       Water rights
     
    Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. Given that these assets represent legal rights granted in perpetuity to the Company, they are not amortized, but are subject to annual impairment tests.
     
    (b)
    Rights of way for electric lines
     
    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. These rights are presented under intangible assets. Amounts paid are capitalized at the date of the agreement and charged to the statement of income, according to the life of the right of way.
     
    (c)
    Computer software
     
    Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives.
     
    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 recognized as assets are amortized over their estimated useful lives.
     
    (d)
    Mining property and concession rights
     
    The Company holds mining property and concession rights from the Chilean Government. Property rights 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.
     
    No impairment of intangible assets exists as of December 31, 2017 and December 31, 2016.
     
    3.26
    Research and development expenses
     
    Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred.
     
    3.27
    Prospecting expenses
     
    The Company has mining property and concession rights from the Chilean Government and others that it has acquired from third parties other than the Chilean Government, destined to the exploitation of caliche ore and saltpeter deposits and also the exploration of these types of deposits.
     
    Upon obtaining these rights, the Company initially records disbursements directly associated with the exploration and evaluation of deposits (associated with small deposits with trading feasibility) as asset at cost. Such disbursements include the following concepts:
     
    -
    Disbursements for geological reconnaissance evaluation
     
    -
    Disbursements for drilling
     
    -
    Disbursements for drilling work and sampling
     
    -
    Disbursements for activities related to technical assessment and trading feasibility of drilling work
     
    -
    And any disbursement directly related to specific projects where its objective is finding mining resources.
     
    Subsequently, the Company distinguishes exploration and evaluation projects according to the economic feasibility of the mineral extracted in the area or exploration, among those that finally will deliver future benefits to the Company (profitable projects) and those projects that are unlikely to bring profit to the Company in the future (i.e., when the ore grade at the site is low and its exploitation is not economically profitable).
     
    If technical studies determine that the ore grade is not economically suitable for exploitation, the asset is directly expensed. Otherwise, it is held in the caption “other non-current assets”, reclassifying the portion related to the area to be exploited in the year in the caption inventories and such amount is amortized as production cost on the basis of estimated tons to be extracted.
     
    The technical reasons for this classification correspond to the fact that this is an identifiable non-monetary asset that is owned to be used in the production of our processes as a main raw material.
     
    For this reason and because our disbursements correspond to reserves that have proved to be financially feasible and used as a principal raw material in our production processes, these are presented as inventories that will be exploited within the commercial year and the remainder as development expenses for small deposits and prospecting expenses in the caption “other non-current assets”.
     
    3.28       Impairment of non-financial assets
     
    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.
     
    The recoverable amount of an asset is the higher between the fair value of an asset or cash generating unit (“CGU”) 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.
     
    When the carrying value of an asset exceeds its recoverable amount, the asset is considered an impaired asset and is reduced to its net recoverable amount.
     
    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.
     
    To determine the fair value less costs to sell, an appropriate valuation model is used.
     
    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, except for properties reevaluated previously where the revaluation was taken to equity.
     
    For assets other than acquired goodwill, an annual evaluation is carried out to determine whether any previously recognized impairment losses have already decreased or ceased to exist. If this should be the case, the recoverable amount is estimated. 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.
     
    3.29       Minimum dividend
     
    As required by the Shareholders’ Corporations Act, unless decided otherwise by a unanimous vote by the shareholders of subscribed and paid shares, a public company must distribute dividends as agreed by the shareholders at the General Shareholders’ Meeting held each year. This must entail a minimum of 30% of its profits, except when the Company records unabsorbed losses from prior years. However, the Company has set a policy to distribute 50% of its profits for the year, unless decided otherwise by a unanimous vote by the shareholders at the General Shareholders´ meeting held each year.
     
    At an extraordinary meeting held on April 11, 2017, the Company’s Board of Directors made a recommendation for discussion at the Ordinary Shareholders’ Meeting (the Meeting), which was held on April 28, 2017, that the Company should distribute and pay dividends based on 100% of the Company’s net profit for distribution for the financial year 2016. This recommendation was accepted by the Meeting.
     
    For 2017, the Company has defined the following dividend policy: (a) To distribute and pay a dividend to the respective shareholders, a percentage of the profits to be determined as follows:
     
    (i) 100% of the profit for 2017 if all the following financial parameters are met: (a) that the total of cash and cash equivalents and other current financial assets (“Cash”) divided by the addition of other current financial liabilities (the “Short-term Financial Liabilities”) is equal to or more than 2.5 times, and (b) the total of current liabilities and non-current liabilities (“Total Liabilities”) divided by total equity (“Equity”) is equal to or less than 1.1 times.
     
    (ii) 80% of profit for 2017 if all the following financial parameters are met: (a) that Cash divided by Short-term Financial Liabilities is equal to or more than 2.0 times, and (b) Total Liabilities divided by Total Equity is equal to or less than 1.2 times.
     
    (iii) 60% of profit for 2017 if all the following financial parameters are met: (a) that Cash divided by Short-term Financial Liabilities is equal to or more than 1.5 times, and (b) Total Liabilities divided by Total Equity is equal to or less than 1.3 times. Should none of these parameters be met, the Company will distribute and pay as dividend 50% of the profit for 2017 to the respective shareholders.
     
    3.30
    Earnings per share
     
    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.
     
    The Company has not conducted any type of operation of potential dilutive effect that would entail the disclosure of diluted earnings per share.
     
    3.31
    Trade and other payables
     
    Trade and other payables are measured at fair value plus all costs associated with the transaction. Subsequently, these are carried out at amortized cost using the effective interest rate method.
     
    3.32
    Interest-bearing borrowings
     
    At initial recognition, interest-bearing borrowings are measured at fair value net of transaction costs incurred. Subsequently, they are measured at amortized cost using the effective interest rate method. Amortized cost is calculated considering any premium or discount from the acquisition and includes costs of transactions which are an integral part of the effective interest rate.
     
    These are recorded as non-current when their expiration period exceeds twelve months and as current when the term is lower than such term. Interest expense is calculated in the year in which it is accrued following a financial criterion.
     
    3.33
    Other provisions
     
    Provisions are recognized when:
     
     
    -
    The Company has a present obligation or constructive obligation as the result of a past event.
     
     
    -
    It is more likely than not that certain resources must be used, including benefits, to settle the obligation.
     
     
    -
    A reliable estimate can be made of the amount of the obligation.
     
    In the event that the provision or a portion of it is reimbursed, the reimbursement is recognized as a separate asset solely if there is certainty of income.
     
    In the consolidated statement of income, the expense for any provision is presented net of any reimbursement.
     
    Should the effect of the value of money over time be significant, provisions are discounted using a discount rate before tax that reflects the liability’s specific risks. When a discount rate is used, the increase in the provision over time is recognized as a finance cost.
     
    The Company’s policy is to maintain provisions to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from current litigation, compensations or obligations, pending expenses for which the amount has not yet been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time the responsibility or the obligation that determines the compensation or payment is generated.
     
    3.34
    Obligations related to employee termination benefits and pension commitments
     
    Obligations towards the Company’s employees comply with the provisions of the collective bargaining agreements in force, which are formalized through collective employment agreements and individual employment contracts, except for the United States, which is regulated in accordance with employment plans in force up to 2002. (See more details in Note 15.4)
     
    These obligations are valued using actuarial calculations, according to the projected unit credit method which considers such assumptions as the mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees’ salaries, as well as the effects on variations in services derived from variations in the inflation rate. The criteria in force contained in the revised IAS 19 are also taken into account.
     
    Actuarial gains and losses that may be generated by variations in defined, pre-established obligations are directly recorded in other comprehensive income.
     
    Actuarial losses and gains have their origin in departures between the estimate and the actual behavior of actuarial assumptions or in the reformulation of established actuarial assumptions.
     
    The discount rate used by the Company for calculating the obligation was 5.111% and 4.522% for the periods ended December 31, 2017 and December 31, 2016, respectively.
     
    The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value using a 3.75% interest rate for 2017 and 4.5% for 2016. The net balance of this obligation is presented under the non-current provisions for employee benefits (refer to Note 15.4).
     
    3.35
    Compensation plans
     
    Compensation plans implemented through benefits provided in share-based payments settled in cash are recognized in the financial statements at their fair value, in accordance with International Financial Reporting Standards No. 2 "Share-based Payments.” Changes in the fair value of options granted are recognized with a charge to payroll on a straight-line basis during the period between the date on which these options are granted and the payment date (see Note 16).
     
    3.36
    Revenue recognition
     
    Revenue includes the fair value of considerations received or receivable for the sale of goods and services during the performance of the Company's activities. Revenue is presented net of value added tax, estimated returns, rebates and discounts and after the elimination of sales among subsidiaries.
     
    Revenue is recognized when its amount can be stated reliably, it is probable that the future economic rewards will flow to the entity and it meets the specific conditions for each type of activity-related revenue, as follows:
     
    (a)       Sale of goods
     
    The sale of goods is recognized when the Company has delivered products to the customer, and there is no obligation pending compliance that could affect the acceptance of products by the customer. The delivery does not occur until products have been shipped to the customer or confirmed as received by the customer, and the related risks of obsolescence and loss have been transferred to the customer and the customer has accepted the products in accordance with the conditions established in the sale, when the acceptance period has ended, or when there is objective evidence that those criteria required for acceptance have been met.
     
    Sales are recognized in consideration of the price set in the sales agreement, net of volume discounts and estimated returns at the date of the sale. Volume discounts are evaluated in consideration of annual foreseen purchases and in accordance with the criteria defined in agreements.
     
    (b)       Sale of services
     
    Revenue associated with the rendering of services is recognized considering the degree of completion of the service as of the date of presentation of the consolidated classified statement of financial position, provided that the result from the transaction can be estimated reliably.
     
    (c)       Interest income
     
    Interest income is recognized when interest is accrued in consideration of the principal pending payment using the effective interest rate method.
     
    (d)       Income from dividends
     
    Income from dividends is recognized when the right to receive the payment is established.
     
    3.37
    Finance income and finance costs
     
    Finance income is mainly composed of interest income in financial instruments such as term deposits and mutual fund deposits. Interest income is recognized in profit or loss at amortized cost, using the effective interest rate method.
     
    Finance costs are mainly composed of interest on bank borrowing expenses, interest on bonds issued and interest capitalized for borrowing costs for the acquisition, construction or production or qualifying assets.
     
    Borrowing costs and bonds issued are recognized in profit or loss using the effective interest rate method.
     
    For finance costs accrued during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, the effective interest rate related to the project’s specific financing is used. If none exists, the average financing rate of the subsidiary making the investment is utilized. Borrowing and financing costs that are directly attributable to the acquisition, construction or production of an asset are capitalized as part of that asset’s cost.
     
    3.38       Income tax and deferred taxes
     
    Corporate income tax for the year is determined as the sum of current taxes from the different consolidated companies.
     
    Current taxes are based on the application of the various types of taxes attributable to taxable income for the year.
     
    Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized.
     
    In conformity with current Chilean tax regulations, the provision for corporate income tax and taxes on mining activity is recognized on an accrual basis, presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and associated credits. The balances of these accounts are presented in current income taxes recoverable or current taxes payable, as applicable.
     
    Tax on companies and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in the statement of income accounts or equity accounts in the consolidated statement of financial position, considering the origin of the gains or losses which have generated them.
     
    At each reporting period, the carrying amount of deferred tax assets has been reviewed and reduced to the extent where there will not be sufficient taxable income to allow the recovery of all or a portion of the deferred tax assets. Likewise, as of the date of the consolidated financial statements, deferred tax assets that are not recognized were evaluated and not recognized as it was more likely than not that future taxable income will allow for recovery of the deferred tax asset.
     
    With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used.
     
    The deferred income tax related to entries directly recognized in equity is recognized with an effect on equity and not with an effect on profit or loss.
     
    Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority.
     
    3.39
    Segment reporting
     
    IFRS 8 requires that companies adopt a “management approach” to disclose information on the operations generated by its operating segments. In general, this is the information that management uses internally for the evaluation of segment performance and making the decision on how to allocate resources for this purpose. 
     
    An operating segment is a group of assets and operations responsible for providing products or services subject to risks and performance that are different from those of other business segments. A geographical segment is responsible for providing products or services in a given economic environment subject to risks and performance that are different from those of other segments operating in other economic environments.
     
    For assets and liabilities, the allocation to each segment is not possible given that these are associated with more than one segment, except for depreciation, amortization and impairment of assets, which are directly allocated to the applicable segments, in accordance with the criteria established in the costing process for product inventories.
     
    The following operating segments have been identified by the Company:
     
    -
    Specialty plant nutrients
    -
    Industrial chemicals
    -
    Iodine and derivatives
    -
    Lithium and derivatives
    -
    Potassium
    -
    Other products and services
     
    3.40   Responsibility for Information and Estimates Made
     
    The Management of Sociedad Química y Minera de Chile S.A. and its subsidiaries is responsible for the information contained in these consolidated financial statements, which expressly indicate that all the principles and criteria included in IFRS, as issued by the International Accounting Standards Board (IASB), have been applied in full. 
     
    In preparing the consolidated financial statements of Sociedad Química y Minera de Chile S.A. and its subsidiaries, Management has made judgments and estimates to quantify certain assets, liabilities, revenues, expenses and commitments included therein. Basically, these estimates refer to:
     
     
    -
    The useful lives of property, plant and equipment, and intangible assets and their residual value Estimated useful lives are determined based on current facts and past experience, and take into consideration the anticipated physical life of the asset, the potential for technological obsolescence, and regulations. See notes 3.22, 13 and 14.
     
     
     
     
    -
    Impairment losses of certain assets - Assets, including property, plant and equipment, exploration assets, goodwill and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their recoverable amounts. If an impairment assessment is required, the assessment of fair value often requires estimates and assumptions such as discount rates, exchange rates, commodity prices, future capital requirements and future operating performance. Changes in such estimates could impact the recoverable values of these assets. Estimates are reviewed regularly by management. See notes 13 and 14.
     
     
     
     
    -
    Assumptions used in calculating the actuarial amount of pension-related and severance indemnity payment benefit commitments. See Note 15.
     
     
     
     
    -
    Contingencies – The amount recognized as a provision, including legal, contractual, constructive and other exposures or obligations, is the best estimate of the consideration required to settle the related liability, including any related interest charges, taking into account the risks and uncertainties surrounding the obligation. In addition, contingencies will only be resolved when one or more future events occur or fail to occur. Therefore, the assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. The Company assesses its liabilities and contingencies based upon the best information available, relevant tax laws and other appropriate requirements. See notes 18 and 19.
     
     
     
     
    -
    Provisions on the basis of technical studies that cover the different variables affecting products in stock (density and moisture, among others), and related allowance.
     
     
    -
    Obsolescence to ensure that the carrying value of inventory is not in excess of the net realizable Inventory valuation requires judgment to determine obsolescence and estimates of provisions for value. See note 8.
     
    Despite the fact that these estimates have been made on the basis of the best information available on the date of preparation of these consolidated financial statements, certain events may occur in the future and oblige their amendment (upwards or downwards) over the next few years, which would be made prospectively, recognizing the effects of the change in estimates in the related future consolidated financial statements.
     
    3.41       Environment
     
    In general, the Company follows the criteria of considering amounts used in environmental protection and improvement as environmental expenses. However, the cost of facilities, machinery and equipment used for the same purpose are considered property, plant and equipment, as the case may be.
