(a)

Subsidiaries

Subsidiaries are all those entities on which Sociedad Química y Minera de Chile S.A. has the control to lead the financial and operating policies, which, in general, is accompanied by participation greater than half the voting rights. Subsidiaries are consolidated from the date in which control is transferred to the Company and are excluded from consolidation on the date in which this control ceases to exist. The subsidiaries apply the same policies applied by its Parent.

In order to recognize the acquisition of an investment, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, of equity instruments issued and of liabilities incurred or assumed at the exchange date plus costs directly attributable to acquisition. Identifiable assets acquired and identifiable liabilities and contingencies assumed in a business combination are initially stated at their fair value at the acquisition date. For each business combination the Company will measure non-controlling of the acquiree either at its fair value or as a proportional amount of the acquiree’s identifiable net assets.

Responsibility for the information and estimates made

The information contained in these interim consolidated financial statements is the responsibility of the Company’s management who expressly indicate that it has applied all the principles and criteria included in IFRS issued by the International Accounting Standard Board (IASB.)

In the Company’s interim consolidated financial statements judgments and estimates have been made by management to quantify certain assets, liabilities. Income, expenses and commitments recorded therein. Basically these estimates refer to the following:

The useful lives of material and intangible assets and their residual values.

Impairment losses of certain assets, including trade receivables.

Hypotheses used for the actuarial calculation of commitments related to pensions and staff severance indemnities.

Provisions for commitments acquired with third parties and contingent liabilities.

Accrued expenses based on technical studies which cover the different variables which affect products in stock (density. humidity. among others) and allowances on slow-moving spare parts in inventories.

Future costs for the closure of mining facilities.

	-	The determination of fair value of certain financial and non-financial assets and derivative instruments.
	-	The determination and allocation of fair values in business combinations.

Although these estimates have been made considering the best possible information available on the date of preparation of these interim financial statements it is possible that events which may occur in the future obligate their modification (increases or decreases) in the next few years, which would be performed prospectively, recognizing the effects of change in estimates on the respective future interim consolidated financial statements.

Financial information by operating segment

IFRS 8 requires that companies adopt “the management approach” to disclose information on the result of 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.

A business segment is a group of assets and operations responsible for providing products or services subject to risks and performance different that 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 different that those of other segments which operate in other economic environments.

For assets and liabilities the assignment to each segment is not possible given that these are associated to more than one segment.

Accordingly, the following business segments have been identified for the Company:

Specialty plant nutrients

Industrial chemicals

Iodine and derivatives

Lithium and derivatives

Potassium

Other products and services

2.7

Property, plant and equipment

Tangible fixed assets are stated at acquisition cost, net of the related accumulated amortization and impairment losses which they have experienced.

In addition to the price paid for the acquisition of tangible fixed assets, the Company has considered the following concepts as part of the acquisition cost, as applicable:

Accrued financial expenses during the construction period which 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. The amount capitalized for this concept was ThUS$5,233 as of March 31, 2011 and ThUS$25,947 as of December 31, 2010.

2	The present value of future costs to which the Company will have to experience related to the closure of its facilities, are included in the asset's value at restated cost.

Work-in-progress is transferred to property, plant and equipment in operation once they are available for use beginning the related amortization on that date.

Extension, modernization or improvement costs which 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 income as cost of the year in which 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.

Based on the impairment analysis conducted by the Company’s management has been considered that the carrying value of assets do not exceed the net recoverable value of these assets.

Property, plant and equipment, net in the case of their residual value, are amortized through the straight-line distribution of cost among the estimated technical useful lives which constitute the period in which the Company expects to use them. When portions of a property, plant and equipment item have different useful lives, these are recorded as separate items. The useful life is reviewed on a regular basis (annually).

The gains or losses which are generated in the sale or disposal of property, plant and equipment are recognized as income for the period and calculated as the difference between the asset’s sales value and its net carrying value.

The Company obtains property rights and mining concessions from the Chilean State. Property rights are obtained usually without any initial cost (other than the payment of mining licenses and minor registration expenses) and when rights are obtained on these concessions, the Company retains them while it pays the related interim licenses. Such license fees, which are paid on an annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties, which are not from the Chilean State are recorded at their acquisition cost in property, plant and equipment.

Costs arising from daily maintenance activities of property, plant and equipment are recognized in profit or loss as and when incurred.

2.8

Investment properties

The Company recognizes as investment properties the net values of land, buildings and other constructions which are held to exploit them under lease agreements or to obtain proceeds from their sale as a result of those increases which are generated in the future in the respective market prices. These assets are not used in the activities and are not destined for own use.

They are initially stated at their acquisition cost, which includes the acquisition price or production cost plus directly assignable expenses. Subsequently, investment properties are stated at their acquisition cost less accumulated depreciation and the possible accumulated provisions for value impairment.

2.9

Inventories

The Company states inventories for the lower of cost and net realizable value. The cost price of finished products and products in progress includes direct costs of materials and; as applicable, labor costs, indirect costs incurred to transform 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 weighted average cost.

The net realizable value represents the estimate of the sales price less all finishing estimated costs and costs which will be incurred in commercialization, sales and distribution processes.

Commercial discounts, rebates obtained and other similar entries are deducted in the determination of the acquisition price.

The Company conducts an evaluation of the net realizable value of inventories at the end of each year recording an estimate with a charge to income when these are overstated. When the circumstances, which previously caused the rebate ceased to exist, or when there is clear evidence of an increase in the net realizable value due to a change in the economic circumstances or prices of main raw materials, the estimate made previously is modified.

The valuation of obsolete, impaired or slow-moving products relates to their net estimated net realizable value.

Provisions on the Company's inventories have been made based on a technical study which covers the different variables which affect products in stock (density, humidity, among others.)

Raw materials, supplies and materials are recorded at the lower of acquisition cost or market value. Acquisition cost is calculated according to the annual average price method.

Trade and other receivables

Trade and other receivables relate to non-derivative financial assets with fixed payments which can be determined and are not quoted in any active market. These arise from sales operations involving the products and/or services which the Company commercializes directly to its customers with no intention of negotiating the account receivable and are not within the following categories:

• Those which the Company has the intention of selling immediately in the near future and which are held-for-sale.

• Those designated at their initial recognition as available-for-sale..

• Those which do not allow that the holder recovers substantially all its initial investment due to circumstances other than credit impairment, which will be classified as available-for-sale.

These assets are initially recognized at their fair value (which is equivalent to their face value, discounting implicit interest for installment sales) 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.

Embedded interest in installment sales is recognized as financial income when interest is accrued over the term of the operation.

Revenue recognition

Revenue includes the fair value of considerations received or receivable or the sale of goods and services during performance of the Company's activities. Revenue is presented net of value added tax, returns, rebates and discounts and after the elimination of sales among subsidiaries.

Revenue is recognized when its amount can be stated reliably, it is possible that the future economic rewards flow to the entity and the specific conditions for each type of activity -related revenue are complied with, as follows:

(a)

Sale of goods

Sales of goods are recognized when the Company has delivered products to the customer, the customer has total discretion on the distribution channel and the price at which products are sold and there is no obligation pending compliance which may 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 customers when the related risks of obsolescence and loss have been transferred to the customer and the customer has accepted products in accordance with the conditions established in the sale, the acceptance period has ended or 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 interim foreseen purchases and in accordance with the criteria defined in agreements.

(b)

Sales of services

Revenue associated with the provision of services is recognized considering the degree of completion of the service at the date of presentation of the Statement of financial position provided that the result from the transaction can be estimated reliably.

(c)

Interest income

Income is recognized as and when interest is accrued in consideration of the principal which is pending payment using the effective interest rate method.

(d)

Income from royalties

Income from royalties is recognized based on the accrual in accordance with the economic substance of the related agreements.

(e)

Income from dividends

Income from dividends is recognized when the right to receive the payment is established.

2.12

Investments recognized using the equity method

Interest in companies in which control is exercised together with another company (joint venture) or in which the Company has significant influence (associated companies) are recorded using the equity method. Significant influence is assumed to exist when the Company has interest exceeding 20% of the investee's equity.

Under this method, the investment is recognized in the statement of financial position at cost plus changes subsequent to the acquisition in an amount proportional to the net associated company’s equity using the ownership interest in the associate. The associated goodwill is included at the carrying value of the investee and it is not subject to amortization. The debit or credit to profit or loss reflects the proportional amount in the associated company's results.

Unrealized gains for transactions with affiliates or associates are eliminated considering the equity interest by the Company in them. Unrealized losses are also eliminated except if the transaction provides evidence of impairment loss of the asset transferred.

Changes in equity of the associates are recognized proportionally with a debit or credit to “Other reserves” and classified according to their origin.

The associate’s and the Company’s reporting dates and policies are similar for equivalent transactions and events under similar circumstances.

In the event that significant influence is lost or the investment is sold or is available-for-sale, the equity value method is discontinued suspending the recognition of proportional results.

If the resulting amount according to the equity method were negative, interest is reflected as zero in the interim consolidated financial statements unless the Company commits to resolve its equity position. In this case, the respective provision for risks and expenses is recorded.

Dividends received in these companies are recorded reducing the equity value and proportional profit or loss recognized in conformity with their interest, are included in the consolidated profit or loss under the caption “Equity gain (loss) in companies and joint ventures using the equity method.”

2.13

Income tax and deferred taxes

Income tax expense for the year is determined as the addition of current tax from the different companies resulting from the application of the type of local tax on the taxable income for each of them. 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 which are expected to be applicable when assets and liabilities are realized.

In conformity with current Chilean tax regulations, the provision for corporate income tax and taxes for the mining activity is recognized on an accrual basis presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and credits associated with it. The balances of these accounts are presented in Current tax assets or liabilities, as applicable.

Tax on companies and variations on deferred tax assets or liabilities which are not the result of business combinations are recorded in profit or loss statement accounts or net equity accounts in the Consolidated Statement of Financial Position considering the origin of the gains or losses which have generated them.

At the end of each reporting period, the carrying value of deferred tax assets is reviewed and reduced as long as it is possible that there is no sufficient taxable income to allow the recovery of all or a portion of the deferred tax asset. Likewise, at the date of the statement of financial position deferred tax assets not recognized are revalued and recognized as long as it has become possible that future taxable income will allow the recovery of the deferred tax asset.

With respect to temporary differences deductible associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that there is a possibility that temporary differences are 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 right legally receivable of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority.

2.14

Earnings per share

The net benefit per share is calculated as the ratio between the net benefit for the period attributable to the Parent Company and the weighted average number of common shares of the Parent Company in circulation during this period.

The Company has not conducted any type of operation of potential diluted effect which assumes a diluted benefit per share other than the basic benefit per share.

2.15

Non-financial asset value impairment

Assets subject to amortization are subject to test for impairment 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 amount in books 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 which 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 discount rate before taxes which reflects current market evaluation on the time value of money and specific asset risks.

An appropriate valuation model is used to determine the fair value less selling costs. These calculations are confirmed by valuation multiples, quoted share prices for subsidiaries quoted publicly or other available fair value indicators.

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. In this case impairment is also recognized with a debit to equity up to the amount of any previous revaluation.

Note 2 - Bases of presentation of interim consolidated financial statements and accounting criteria applied (continued)

For assets other than the goodwill acquired, an annual evaluation is conducted of whether there are impairment loss indicators recognized previously which might have already ceased to exist or decreased. The recoverable amount is estimated if such indicators exist. An impairment loss previously recognized is reversed only if there have been changes in estimates used to determine the asset’s recoverable amount from the last time in which 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 which would have been determined net of depreciation if an asset impairment loss would have not been recognized in prior years. This reversal is recognized with a credit to profit or loss unless an asset is recorded at the revaluated amount. Should this be the case, the reversal is treated as an increase in revaluation.

2.16 Financial assets

SQM S.A. and subsidiaries classify their financial statements under the following categories: at fair value through profit or loss, loans and receivables, financial assets held-to-maturity and financial assets available-for-sale. The classification depends on the purpose with which financial assets were acquired. Management determines the classification of its financial assets at the time of initial recognition.

At each reporting date, the Company assesses whether there is objective evidence that an asset or group of financial assets is impaired or has been impaired. An asset or group of financial assets is impaired if and only if, there is objective evidence of impairment as a result of one or more events occurred after the initial recognition of the asset or group of assets. The recognition of impairment necessitates that the loss event has an impact on the estimate of the future cash flows from the asset or group of financial assets.

(a)

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for trading. A financial asset is classified in this category if it is acquired mainly with the purpose of being sold in the short-term. Derivatives are also classified as acquired for trading unless they are designated as hedge accounting. Assets under this category are classified as current assets and variations generated in fair value are directly recognized in profit or loss.

(b)

Loans and receivables

Loans and accounts receivable are non-derivative financial assets with fixed payments or payments which can be determined and are not quoted in any active market. These are included in current assets, except for those with expiration dates which exceed 12 months from the closing date which are classified as non-current assets. Loans and receivables are included under the caption “Trade and other receivables” in the Statement of financial position and are stated at amortized cost. The subsequent measurement at amortized cost I used for its calculation the effective interest rate less impairment.

(c)

Financial assets held-to-maturity

Financial assets held-to-maturity are non-derivative financial assets with fixed payments or payments which can be determined and fixed expiration dates which management has the positive intention and ability of holding to maturity. If an amount which was not insignificant of financial assets held to maturity was sold, the full category would be reclassified as available for sale. Assets in this category are stated at amortized cost.

(d)

Financial assets available for sale

Financial assets available for sale are non-derivative instruments which are designated in this category or are not classified in any of the other categories. They are included in non-current assets unless the Company intends to dispose of the investment in the 12 months following the closing date. These assets are stated at fair value recognizing under other reserves those variations in fair value, if any.

2.17 Financial liabilities

The Company classifies its financial liabilities under the following categories: at fair value through profit or loss, trade payables, interest-bearing loans or derivatives designated as hedging instruments.

The Company’s management determines the classification of its financial liabilities at the time of initial recognition.

Financial debt obligations are recorded at nominal amount as non-current when its expiration term exceeds twelve months and as current when it is lower than that term. Interest expenses are computed in the year in which they are accrued following a financial criterion.

In conformity with IAS 32 and IAS 39, borrowing costs are recorded in the attached Consolidated Statement of Financial Position discounting the associated debt and are debited to profit or loss for the year in the same term that the debt using the effective interest rate method.

Financial liabilities are derecognized when the obligation is repaid, settled or it expires.

(a)

Financial liabilities at fair value through profit or loss

Financial liabilities are classified at fair value when these are held for trading or designated in their initial recognition at fair value through profit or loss. This category includes derivative instruments not designated for hedge accounting.

(b)

Trade payables

Trade payables to suppliers are subsequently stated at their amortized cost using the effective interest rate method.

(c)

Interest-bearing loans

Loans are subsequently stated 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.

2.18 The Environment

In general, the Group companies follow the criterion of considering amounts destined to environmental protection and improvement as environmental expenses. However, amounts of elements included in facilities, machinery and equipment destined to the same purpose are considered property, plant and equipment as the case may be.

2.19 Minimum Dividend

As required by the Shareholders’ Company Act unless otherwise decided by the shareholders through unanimous vote of the holders of those shares issued and subscribed, a public shareholders’ company must distribute a minimum dividend of 30% of its profit for the period, except in the event that the Company has losses not absorbed in prior years.

2.20 Consolidated statement of cash flows

Cash equivalents relate to short-term highly liquid investments which are readily convertible into known amounts of cash are subject to low risk of change in their value and expire in less than three months from the date of acquisition of the instrument.

For the purposes of the preparation of the statement of cash flows, cash has been defined as cash and cash equivalents as defined above.

The statement of cash flows includes cash movements performed during the year determined by the indirect method.

In these statements of cash flows, the following expressions are used in the sense which is shown as follows:

Cash flows: cash and financial asset equivalent inflows and outflows understanding as such those short-term highly-liquid investments with low risk of change in their value.

Obligations related to staff severance indemnities and pension commitments

Obligations with the Company’s employees are in accordance with that established in the collective bargaining agreements in force formalized through collective employment agreements and individual employment contracts, except for the United States, which is regulated by employment pensions plans.

These obligations are valued using the actuarial calculation, which considers such hypotheses 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.

Actuarial losses and gains which may be generated by variations in previously defined obligations are directly recorded in profit or loss.

Actuarial losses and gains have their origin in deviations between the estimate and the actual behavior of actuarial hypotheses or in the reformulation of those actuarial hypotheses established.

The discount rate used by the Company for the calculation of the obligation was 6% for the periods ended as of March 31, 2011 and December 31, 2010.

Our subsidiary SQM North America has established with its employees pensions plans for retired employees, which are calculated measuring the forecasted liability for expected future severance indemnities using the salary progression rate net of adjustments for inflation, mortality and turnover assumptions discounting the amount resulting at the present value using an interest rate of 6.5% for 2010 and 2009. The net balance of this liability is presented under non-current provisions for employee benefits.

2.22 Financial derivatives and hedging transactions

Derivatives are recognized initially at fair value at the date in which the derivatives contract has been signed and subsequently they are valued again at fair value. The method for recognizing the resulting loss or gain depends on whether the derivative has been designated as an accounting hedging instrument and, if so, depends on the type of hedging performed by the Company, 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 possible foreseen transaction (cash flow hedge);

At the beginning of the transaction, the Company documents the relationship existing between hedging instruments and those entries 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 the end of each period of whether derivatives which are used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged entries.

The fair value of derivative instruments used for hedging purposes is shown in Note 8.3 (Hedging assets.) Movements in the hedging operation reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged entry is higher than 12 months and as a current asset or liability if the remaining expiration period of the entry is lower than 12 months.

Investment derivatives are classified as a current asset or liability and the change in their fair value is recognized directly in profit or loss.

(a)

Fair value hedge

The change in the fair value of a derivative is recognized with a debit or credit to profit or loss, as applicable. The change in the fair value of the hedged entry attributable to hedged risk is recognized as part of the carrying value of the hedged entry and is also recognized with a debit or credit to profit or loss.

Notes to the interim consolidated financial statements as of March 31, 2011

Note 2 - Bases of presentation of interim consolidated financial statements and accounting criteria applied (continued)

For fair value hedging related to items recorded at amortized cost, the adjustment of the fair value is amortized against income on the remaining year to its expiration. Any adjustment to the carrying value of a hedged financial instrument for which effective rate is used is amortized with a debit or credit to profit or loss at its fair value attributable to the risk being covered.

If the hedged entry is derecognized, the fair value not amortized is immediately recognized with a debit or credit to profit or loss.

(b)

Cash flow hedge

The cash portion of gains or losses from the hedging instrument is initially recognized with a debit or credit to other reserves whereas any non-cash 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 for the period as when the hedged finance income or expense is recognized when a forecasted sale occurs. When the hedged entry is the cost of a non-financial asset or liability, amounts recorded in other reserves are transferred to the initial carrying value of the non-financial asset or liability.

Should the expected firm transaction or commitment not longer be expected to occur, the amounts previously recognized in equity are transferred to profit or loss. If a hedging instrument expires is sold, finished, and exercised without any replacement or a rollover is performed or if its designation as hedging is revoked. Amounts previously recognized in other reserves are maintained in equity until the expected firm transaction or commitment occurs.

2.23 Lease

(a)

Leases - Finance lease

Leases are classified as finance leases when the Company has substantially all the risks and rewards derived from the ownership. 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 financial debt to obtain ongoing interest type on the debt pending balance. The respective lease obligations, net of financial debt, are included in other non-current liabilities. The interest element of finance cost is debited in the statement of comprehensive income during the lease period so that a regular ongoing interest rate is obtained on the remaining balance of the liability for each year. The asset acquired through a finance lease is subject to depreciation over the lower of its useful life or the life of the agreement.

(b)

Lessee – Operating lease

Leases in which the lesser maintains a significant part of 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 comprehensive income or capitalized (as applicable) on a straight-line basis over the lease period.

Exploration and assessment expenses

Those exploration and assessment expenses associated with mineral reserves which are being exploited are included under Inventories and amortized according to the estimated mineral content reserves. Expenses associated with future reserves are presented under Other non-current non-financial assets as and when minerals included in the future reserve have ore-grade which makes the mining property economically exploitable.

Those expenses incurred on properties in which the product has low ore-grade which is not economically exploitable, are directly debited to profit or loss.

2.25 Other provisions

Provisions are recognized when:

The Company has a present obligation as a result of a past event.

It is possible that certain resources are used, including benefits, to settle the obligation.

A reliable estimate can be made of the obligation amount.

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 statement of comprehensive income, the expense for any provision is presented net of any reimbursement.

Should the effect of the time value of money be significant, provisions are discounted using a discount rate before taxes which 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 maintaining accruals to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from litigation in force, compensations or obligations, pending expenses the amount of which has not been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time in which the responsibility or the obligation which determines the compensation or payment is generated.

Water rights

Water rights acquired by the Company relate to the water from natural sources and are recorded at acquisition cost. Given that these assets represent rights granted on a perpetual basis to the Company, these are not amortized. However, they are subject to an impairment assessment on an annual basis.

(c)

Right 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 in third party land.

Note 3 – Financial Risk Management

3.1 Risk Management Policy

The Company’s Risk Management Strategy is focused on safeguarding the Company and its subsidiaries’ stability and sustainability with respect to those relevant financial uncertainty components.

The Company’s operations are subject to certain risk factors which may affect its financial position or results. The most significant among these are market, liquidity, exchange rate, uncollectible and interest rate risks.

There may be additional risks affecting the Company’s trading operations, its business, financial position or results, which are not significant through the present date.

The financial risk management structure includes the identification, determination, analysis, quantification, measurement and control of these events. The Company’s management and, in particular, the Finance Management is responsible for the ongoing evaluation of financial risk. The Company uses derivatives to hedge a significant portion of these risks.

Note 3 – Financial Risk Management (continued)

3.2 Risk Factors

3.2.1 Market risk

Market risks relate to those uncertainties associated with variations in market variables affecting the Company's assets and liabilities among which we may highlight the following:

Country Risk: The economic condition of countries where the Company operates may affect its financial position. For instance, sales by the Company to emerging markets expose it to risks related to economic conditions and trends in those countries. In addition, inventory levels may also be affected by the economic condition in these countries and/or the global economy, among other possible economic impacts.

Price volatility risk: The Company’s product prices are affected by variations in international prices of fertilizers and chemicals and changes in production capacities or in the demand for these might affect our business, financial condition and results from operations.

Commodity price risk: The Company is exposed to changes in prices of raw materials and energy which may have an impact on its production costs and generate unstable results.

Currently, the Company incurs annual direct expenses of approximately US$ 70 million for fuels, gas and equivalents and approximately US$50 million for direct use of electric energy. Variations of 10% in the prices of energy required for the Company’s activities may give rise to variations of US$12 million in costs.

3.2.2 Uncollectibility Risk

As evidenced by the last financial crisis, the global economic downturn and its potential negative effects on the financial position of our customers may extend the terms for the payment of accounts receivable. may increase our bad debt exposure. Although we take steps to minimize risk, this global economic situation may result in losses which might have a material adverse effect on our business, financial condition or results of operations.

In order to mitigate these risks, the Company uses such actions as the use of credit insurance, letters of credit and advance payments for a portion of trade receivables.

Note 3 – Financial Risk Management (continued)

3.2.3

Exchange rate risk

As a result of the influence in the determination of price levels, its relationship to selling costs and given that a significant portion of the Company’s business is traded in that currency, the Company has defined U.S. dollar as its functional currency. However, the global nature of the Company’s business generates exposure to exchange rates of different currencies with respect to U.S. dollars. Accordingly, the Company maintains hedging agreements to cover its main uncovered positions (net assets from liabilities) in currencies other than U.S. dollar against the variation in the exchange rate and regularly updates these agreements depending on the uncovered position to be hedged in those currencies.

A significant portion of the Company’s costs, especially payroll, relates to Chilean peso. Accordingly, an increase or decrease in the exchange rate for U.S. dollar would affect the Company’s profit o loss. Approximately between US$ 350 million and US$370 million of the Company’s costs relate to Chilean pesos which are hedged by operations in derivative instruments covering the unhedged position of balance in this currency.

As of December 31, 2010, the Company had derivative instruments classified as exchange and interest rate hedges associated with all the Company’s obligations related to bonds payable denominated in Chilean pesos and UF, for a fair value of US$97.5 million. As of March 31, 2011, this balance amounts to US$83.4 millions both in favor of SQM.

As of March 31, 2011, the exchange rate for U.S. dollar was Ch$ 479.46 per US$1.00 and Ch$ 468.01 per US$1.00 as of December 31, 2010.

Note 3 – Financial Risk Management (continued)

3.2.4 Interest rate risk

Interest rate fluctuations, mainly due to the uncertainty related to the future market behavior may have a material impact on the Company’s financial statements.

The Company has short and current and non-current financial debt valued at LIBOR + a spread. The Company is subject to fluctuations in such a rate as it does not currently have any derivative instruments to hedge variations in the LIBOR rate.

As of March 31, 2011, the Company has approximately 19% of its financial obligations valued at LIBOR rate and therefore, significant increases in this rate might have an impact on its financial condition. A 100 base point variation on this rate may result in variations in finance costs close to an annual amount of US$ 2.2 million. However, it is actually significantly offset by the returns from the Company’s investments which are also highly related to the LIBOR rate.

Additionally, as of March 31, 2011, on total financial debt principal, the Company maintains a percentage near 12% expiring in less than 12 months, decreasing its exposure to interest rate variations.

3.2.5 Liquidity risk

Liquidity risk is related to the needs for funds to deal with payment obligations. The Company’s objective is maintaining financial flexibility through a comfortable balance between fund requirements and cash flows from normal operating activities, bank loans, public bonds payable, short-term investments and marketable securities, among others.

The Company maintains a significant capital expenditure program which is subject to risks and uncertainties. Mainly the exploration and exploitation of reserves, mining and processing costs and compliance with applicable standards, require significant capital which are subject to variations throughout time.

In addition, world financial markets are subject to downturn and expansion periods, which cannot be foreseen at long-term and may affect access to financial resources by the Company.

These factors may have a material adverse impact on our business, financial condition and the Company’s results of operations.

Accordingly, conducts an ongoing follow-up of the reconciliation of its investments and as part of its risk management strategy, looks after the expiration dates of both from a conservative perspective. As of March 31, 2011, the Company had unused credit facilities available for a total of US$637 million and additional credit facilities committed of US$40 million, available should it require any additional fund.

The other cash and cash equivalents position generated by the Company is invested in highly liquid mutual fund units with AAA risk rating.

3.3 Risk Measurement

The Company has methods to measure the effectiveness and efficiency of risk strategies both in prospective and retrospective manner. These methods are consistent with the Group’s risk management profile.

Note 7 – Related Parties: Disclosures

7.1 Disclosures on related parties

Balances pending at year-end are not guaranteed, accrue no interest and are settled in cash. No guarantees have been delivered or received for trade and other receivables due from related parties or trade and other payables due to related parties. For the period ended March 31, 2011, the Group has not recorded any impairment in receivables related to amounts owed by related parties. This evaluation is conducted every year through an examination of the financial position of the related party in the market in which it operates.

7.2 Relationships between the parent company and the entity

According to that provided in the by-laws of SQM S.A., no shareholder can concentrate more than 32% of the Company’s voting right capital.

Sociedad de Inversiones Pampa Calichera S.A. and Global Mining Investments (Chile) S.A. and collectively, the Pampa Group, are the owners of a number of shares which is equivalent to 29.44% as of March 31, 2011 of the current total amount of shares issued, subscribed and paid of SQM S.A. In addition, Kowa Company Ltd., Inversiones La Esperanza (Chile) Limitada, Kochi S.A. and La Esperanza Delaware Corporation, collectively Kowa Group, are the owners of a number of shares equivalent to 2.08% of the total amount of shares issued, subscribed and paid of SQM S.A.

The Pampa Group and the Kowa Group have informed SQM S.A., the Chilean SVS and the pertinent stock exchanges in Chile and abroad that they are not and have never been related parties between them. In addition, this is regardless of the fact that both Groups on December 21, 2006 have subscribed a joint venture agreement with respect to those shares. Consequently, the Pampa Group, by itself, does not concentrate more than 32% of voting right capital of SQM S.A. and the Kowa Group does not concentrate by itself more than 32% of voting right capital of SQM S.A.

Likewise, the joint venture agreement has not transformed the Pampa Group and the Kowa Group in related companies between them. The joint venture agreement has only transformed the current controller of SQM S.A. composed of the Pampa Group and the Kowa Group into related parties of SQM S.A.

Note 8 - Financial Instruments (continued)

8.3	Hedging assets (continued)

The Company uses cross currency swap derivative instruments to hedge the possible financial risk associated with the volatility of the exchange rate associated with Chilean pesos and UF. The objective is hedging the exchange rate financial risks associated with bonds payable. Hedges are documented and tested to measure its effectiveness.

Based on a comparison of critical terms, hedging is highly effective given that the hedged amount is consistent with obligations maintained for bonds denominated in Chilean pesos and UF. Likewise, hedging contracts are denominated in the same currencies and have the same expiration dates of bond principal payments.

Hedge accounting

SQM classifies derivative instruments as hedges which may include derivatives or embedded derivatives, either as fair value hedging derivative instruments, cash flow derivative instruments or net hedging derivative instruments in business abroad.

a) Fair value hedges

The change in the derivative instruments denominated at fair values which qualify as fair value hedging instruments are recorded immediately in profit or loss together with any change in the fair value of the hedged item attributable to the hedged risk.

The Company documents the relationship between hedging instruments and the hedged item together with the objectives of its risk management and its strategy to perform different hedging transactions. In addition, at the beginning of the hedge and then quarterly the Company documents whether the hedge has been efficient in its objective of hedging market variations for which we use an effectiveness test. Cash is considered the hedging instrument in the event that the test obtains an effectiveness result between 80% and 120%.

Effectiveness tests show results which make consider hedge as effective or ineffective. To-date, effectiveness tests have defined hedges as effective. This note presents the detail of fair values of derivative instruments qualified as hedges.

b) Cash flow hedges

These hedge the variation of cash flows attributed to a risk associated, in particular, to a transaction with high probability of execution, which may have material effects on the Company’s profit or loss. To-date, the Company has not classified any such hedges.

8.9	Estimated fair value of financial instruments and derivative financial instruments

As required by IFRS, the following information is presented for the disclosure of the estimated fair value of financial assets and liabilities.

Although inputs represent Management's best estimate, they are subjective and involve significant estimates related to the current economic and market conditions, as well as risk features.

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

Cash equivalent approximates fair value due to the short-term maturities of these instruments.

Other current financial liabilities are considered at fair value equal to their carrying values.

For interest-bearing liabilities with original maturity of more than a year, fair values are calculated at discounting contractual cash flows at their original current market rates with similar terms.

For forward and swap contracts, fair value is determined using quoted market prices of financial instruments with similar characteristics.

Policies on defined benefit plan

This policy is applied to all benefits recognized received for services provided by the Company's employees.

Short-term benefits for active employees are represented by salaries, social welfare benefits, paid time-off, sickness leaves and other leaves, profit sharing and incentives and non-monetary benefits; e.g., healthcare service, housing, subsidized or free goods or services. These will be paid in a term which does not exceed twelve months.

The Company only provides compensation and benefits to active employees, except for SQM North America which is explained in 16.4.

For each incentive bonus delivered to the Company’s employees, there will be a disbursement in the first quarter of the following year and this will be calculated based on Profit for the period at the end of each period applying a factor obtained subsequent to the employee appraisal process.

The personnel benefits includes withholding bonds for the Company’s executives which relates to the Company’s share prices that is payable in cash, the short-term portion is expressed as current provision for employee benefits and the long-term as non-current provision for employee benefits.

The personnel benefits include a bonus provided to the Company’s directors is calculated based on Profit for the period at each year-end and will consider the application of a percentage factor.

The benefit relates to vacations (short-term (current) benefits to employees), which is provided in the Labor Code which indicates that employees with more than a year of service will be entitled to annual holidays for a period not lower than fifteen paid business days. The Company provides the benefit of two additional vacation days.

Staff severance indemnities are agreed and payable based on the last salary for each year of service for the Company or with certain maximum limits in respect to the number of years to be considered or in respect to monetary terms. In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and the right for its collection can be acquired because of different causes, as indicated in the respective agreements; e.g., retirement, dismissal, voluntary retirement, incapacity or disability, death, etc.

Law No. 19,728 published on May 14, 2001 which became effective on October 1, 2002 required “Compulsory Unemployment Insurance” in favor of all depending employees regulated by the Chilean Labor Code. Article 5 of this law provided the financing of this insurance through monthly contribution payments by both the employee and the employer.

Staff severance indemnities have been calculated under the actuarial assessment method of the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans which consist of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees.

The methodology followed to determine the accrual for all the employees adhered to agreements considers turnover and salary increase rates according to the valuation method referred to as Accumulated Benefit Valuation or Accrued Cost of the Benefit Method. This methodology is established in IAS 19.

Note 15 - Employee benefits (continued)

About the characteristics of the indemnity fund

Under this benefit plan, the Company retains the obligation for the payment of staff severance indemnities related to retirements without establishing a separate fund with specific assets, which is referred to as not funded. The discount interest rate of expected flows to be used was 6%.

Benefit payment conditions

The staff severance indemnity benefit relates to remuneration days for year worked for the Company with no limit of salary or years of services for the Company, when employees cease to work for the Company due to turnover or death. In this case, the maximum age for men is 65 years and 60 years old for women, which are the usual ages for retirement due to achieving the senior citizen age according to the Chilean pensions system provided in Decree Law 3,500 of 1980.

Methodology

The determination of the obligation for benefits under IAS 19, Projected Benefit Obligation (PBO) is described as follows:

To determine the Company's total liability, we used a mathematical simulation model which was programmed using a computer and which processed the situation of each employee on an individual basis.

This model considered months as discrete time; i.e., the Company determined the age of each person and his/her salary on a monthly basis according to the growth rate. Thus, information on each person was simulated from the beginning of the life of his/her employment contract or when he/she started earning benefits up to the month in which it reaches the normal retirement age, generating in each period the possible retirement according to the Company’s turnover rate and the mortality rate according to the age reached. When he/she reaches the retirement age, the employee finishes his/her service for the Company and receives indemnity related to retirement due to old age.

The methodology followed to determine the accrual for all the employees adhered to agreements has considered turnover rates and the mortality rate RV-2010 established by the Chilean Superintendence of Securities and Insurance to calculate pension-related life insurance reserves in Chile according to the Accumulated Benefit Valuation or Accrued Cost of Benefit Method. This methodology is established in IAS 19 Retirement Benefit Costs.

Note 24 – The Environment

24.1	Disclosures on disbursements related to the environment

The Company is continuously concerned with protecting the environment both in its production processes and with respect to products manufactured. This commitment is supported by the principles indicated in the Company’s Sustainable Development Policy.

SQM is currently operating under an Environmental Management System (EMS) which has allowed strengthening its environmental performance through the effective application of the Company’s Sustainable Development Policy

Operations that use caliche as a raw material are carried out in desert areas with climatic conditions that are favorable for drying solids and evaporating liquids using solar energy. Operations involving the open-pit extraction of minerals, due to their low waste-to-mineral ratio, generate remaining deposits that slightly alter the environment. During the extraction process and subsequent crushing of ore, particle emissions occur, which is normal for this type of operation. Caliche extractive operations are performed at an open-sky.

A portion of the ore extracted is crashed, a process in which particle emissions occur; currently this operation is conducted only in the worksite of Pedro de Valdivia. Nearby María Elena, crushing units used to operate which affected the air quality. The Company has implemented a series of measures that have shown notable improvement in air quality at Maria Elena and beginning on March 2010, no ore crushing process is conducted in the aforementioned location.

A large part of our products are shipped in bulk at the Tocopilla Port. In 2007, Tocopilla was declared as a Zone Saturated by Breathable Particulate Matter (MP10), mainly caused by the emissions by electric power plants operating in areas nearby. In October 2010, a plan referred to as “Decontamination Plan of Tocopilla” became effective, to which SQM has committed to apply several measures in order to mitigate this particulate matter that may generate the movement of products in bulk in our port. These measures have been successfully implemented from 2007 to the present date.

The Company carries out environmental follow-up and monitoring plans based on specialized scientific studies, and it also provides an annual training program in environmental matters to both its direct employees and its contractors’ employees. Within this context, SQM entered into a contract with the National Forestry Corporation (CONAF) aimed at researching the activities of flamingo groups that live in the Salar de Atacama (Atacama Saltpeter Deposit) lagoons. Such research includes a population count of the birds, as well as breeding research. Environmental monitoring activities carried out by the Company at the Salar de Atacama and other systems in which it operates are supported by a number of studies that have integrated diverse scientific efforts from prestigious research centers, including Dictuc from Pontificia Universidad Católica in Santiago and the School of Agricultural Science of Universidad de Chile.

Furthermore, within the framework of the environmental studies which the Company is conducting, the Company is performing significant activities in relation to the recording of Pre-Columbian and historical cultural heritage, as well as the protection of heritage sites, in accordance with current Chilean laws. These activities have been especially performed in the areas surrounding María Elena and the Nueva Victoria plants. This effort is being accompanied by cultural initiatives within the community and the organization of exhibits in local and regional museums.

In accordance with paragraph No. 81, letter c) of IAS 12, the Company has estimated that the method which discloses more significant information for the users of its financial statements is the reconciliation of tax expense (income) to the result of multiplying income for accounting purposes by the rate in force in Chile. This option is based on the fact that the Parent Company and its subsidiaries incorporated in Chile generate almost the total amount of tax expense (income) and the fact that amounts of subsidiaries incorporated in foreign countries have no relevant significance within the context of the total amount of tax expense (income.)

b. Included a new article 64 ter to the legal document referred to above related to how to determine the taxable profit for mining operations that, prior to the date of this amendment was dealt with in the article 64 bis replaced by the aforementioned law;

c. Amendment of article 11 ter of Decree Law 600, of 1974, and

d. Established temporary and optional standards, which investors may invoke provided that they are subject to articles 7, 11 bis and 11 ter of Decree Law 600, of 1974; transitional article 5 of Law 20,026, and can also be invoked by companies that do not receive contributions from foreign investors and are regulated by transitional article 4.

The subsidiaries SQM Salar S.A. and SQM Nitratos S.A. requested the approval to be entitled to invoke the transitional article 4 from the Ministry of Economy in order to opt beginning in 2013 and up to 5 years, to an non-variable rate of 5% as specific tax on mine. As of the date of these financial statements, the approval process is in process.

Consequently, for 2010, 2011 and 2012, there is a change in the method to determine the tax applicable to the mining activity, paying based on the mining operating margin obtained by these Companies. As of March 31, 2011, for this purpose, the Company made a provision with a charge to profit or loss of ThUS$13,565.

Notes to the interim consolidated financial statements as of March 31, 2011

Note 30 – Impairment of assets

Assets value impairment

The Company assesses on an annual basis any impairment on the amount of Buildings, plant and equipment, intangible assets, goodwill and investments accounted for using the equity method of accounting, in accordance with IAS 36. Assets to which this methodology applies are as follows:

Investments recognized using the equity method of accounting

Property, plant and equipment

Intangible assets

Goodwill

a)	Impairment of investments recognized using the equity method of accounting, property, plant and equipment, intangible assets and goodwill.

Assets are reviewed for impairment as to the existence of any indication that the carrying value is lower than the recoverable amount. If such an indication exists, the asset recoverable amount is calculated in order to determine the extent of this impairment, if any. In the event that asset does not generate any cash flows independent from other assets, the Company determines the recoverable amount of the cash generating unit to which this asset belongs according to the business segment (specialty plant nutrient, iodine and derivatives, lithium and derivatives, industrial chemicals, potassium and other products and services.)

The Company conducts impairment tests to intangible assets and goodwill with indefinite useful life on an annual basis and every time there is indication of impairment.

If the recoverable value of an asset is estimated in an amount lower than its carrying value, the latter decreases to its recoverable amount.

Note 30 – Impairment of assets (continued)

b)	Impairment of financial assets: For the case of financial assets with a trading origin, the Company has defined a policy for the recognition of provision for impairment in consideration of the age of the past due balance.

Notes to the interim consolidated financial statements as of March 31, 2011

An allowance is made for impairment losses related to trade receivables when there is objective evidence that the Company will be not able to collect all the amounts owed in accordance with the original terms of receivables.

In accordance with the information presented and evaluating the indication of value impairment of any asset related to the cash flow generating unit, we may conclude that there is no evidence of indication which supports any impairment in the value of assets. Depending on value impairment indication, for the entity:

There are no indications of value impairment in each of intangible assets with an indefinite useful life, as well as intangible assets which are not yet available for their use, comparing their carrying amounts to their recoverable amounts.

There are no indications of value impairment on goodwill acquired in a business combination
