Note 1.

Identification and business of Sociedad Química y Minera de Chile S.A. and Subsidiaries

Historic Background

Sociedad Química y Minera de Chile S.A. (the “Company”) is an open stock corporation organized under the laws in the Republic of Chile. The Company was constituted by public deed issued on June 17, 1968 by the Notary Public of Santiago Mr. Sergio Rodríguez Garcés. Its existence was approved by Decree No. 1.164 of June 22, 1968 of the Ministry of Finance, and it was registered on June 29, 1968 in the Business Registry of Santiago, on page 4.537 Nº 1.992. The Parent Company is located at El Trovador 4285, Floor 6, Las Condes, Santiago, Chile. Its phone No. is (56-2) 425-2000.

The Company is registered with the Securities Registry of the Chilean Superintendence of Securities and Insurance (SVS) under No. 0184 dated March 18, 1983 and is subject to the inspection of the SVS.

Our products are divided into five main categories, as follows:

Specialty Plant Nutrition: Products in this business line are niche fertilizers, used in specialty crops. This business is characterized by being closely related to its customers to which it has specialized staff who provide expert advice in best practices for fertilization according to each type of crop, soil and climate. Potassium derived fertilizers, and in particular potassium nitrate, play an important role in crop development, and they also improve post-harvest shelf life, quality, flavor and fruit color. Products in this business line include potassium nitrate, which is sold in multiple grades and as a part of other specialty mixtures, sodium nitrate and potassium sodium nitrate, and more than 200 specialty blends.

Iodine: SQM is the largest global producer of iodine, a product widely used in a variety of industries such as pharmaceutical, technological and health/nutrition. During the 8 years prior to the economic crisis, demand for iodine grew between 6% and 7% per year mainly due to its use in x ray contrast media and polarizing film for LCD displays. This growth trend should return to the industry in the short-term.

Lithium: Lithium is widely used in rechargeable batteries for cell phones, cameras and laptops. The sale of lithium grew at an average annual rate of 7% to 8% in the 10 years leading up to the financial crisis. During the financial crisis, overall consumption fell significantly. SQM is the worldwide leader in the production and sale of lithium. Demand growth should return to pre-crisis rates in the short term. Through the development of lithium-based products, SQM provides important resources to face modern challenges, such as the efficient use of energy and raw material. Lithium is not only used in rechargeable batteries and in technologies for electric cars, but also used in industrial applications to lower melting temperature, helping to save energy and reduce costs.

Industrial Chemicals: Industrial chemicals include various products that are used inputs in a number of production processes. SQM has participated in this business line for more than 30 years producing sodium nitrate, potassium nitrate, boric acid and potassium chloride. In recent years a new, important application has developed in the field of renewable energy; sodium nitrate and potassium nitrate are being used in new solar energy plants to store thermal energy. There are currently projects being developed in countries such as Spain and the United States, as these countries aim to reduce their CO2 emissions

Potassium: Potassium is a essential primary macro-nutrient that, although not part of a plant’s structure, has a significant role in the development of its basic functions. Potassium increases post-harvest shelf life, improves flavor, vitamin content and physical appearance. In this business line, SQM produces and sells potassium chloride and potassium sulfate, both produced from brines extracted from the Salar de Atacama salt flat in the north of Chile. In this business line SQM has focused a significant part of it investments plan, allowing a significantly increase in the Company’s production levels in the last2 years.

2.3

Transactions in foreign currency

(a)	Functional currency and presentation

The Company’s interim consolidated financial statements are presented in United States dollars, which is the Company’s functional and presentation currency and is the currency of the primary economic environment in which it operates.

Consequently, the term foreign currency is defined as any currency other than U.S. dollar.

The interim consolidated financial statements are presented in thousands of U.S. dollars with no decimals.

(b)	Transactions and balances

Transaction balances denominated in a currency other than the functional currency (U.S. dollar) are converted using the exchange rate in force of the functional currency at the transaction date. Monetary assets and liabilities denominated in a foreign currency are converted at the exchange rate of the functional currency prevailing at the closing date of the consolidated statement of financial position. All differences are recorded with a charge or credit to income for the period, except if they are deferred in net equity.

Changes in the fair value of monetary titles denominated in foreign currency classified as available-for-sale are analyzed between translation differences resulting from changes in the amortized cost of the title and other changes in the amount of the title in the accounting records. Translation differences are recognized in net income for the year or period, as applicable and other changes in the amount in the accounting records are recognized in net equity.

Translation differences on non-monetary entries such as equity instruments held at fair value with changes in income are presented as part of the gain or loss in fair value. Translation differences on non-monetary entries are included in net equity in the restatement reserve.

(c)	Group entities

The results, assets and liabilities of all those entities with a currency other than the presentation currency are converted to the presentation currency as follows:

Assets and liabilities are converted at the closing date exchange rate on the balance date.

Income and expenses in each income statement account are converted at average exchange rates.

All resulting exchange differences are recognized as a component separate from net equity.

In consolidation, exchange differences which arise from the conversion of a net investment in foreign entities and of loans and other instruments denominated in foreign currency designated as hedging for those investments are taken to net shareholders’ equity. At the disposal date, these exchange differences are recognized in the statement of income as part of the loss or gain from the sale.

2.4

Basis of Consolidation

(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.

In order to account for 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 regardless of the scope of minority interest. The excess in acquisition cost over the fair value of the participation in identifiable net assets acquired is recognized as goodwill.

The conversion of the financial statements of foreign companies with functional currency other than U.S. dollars is performed as follows:

Assets and liabilities using the exchange rate prevailing on the closing date of the interim consolidated financial statements.

Income statement account entries using the average exchange rate for the year.

Net shareholders’ equity is stated at the historic exchange rate prevailing at the date of acquisition (or at the average exchange rate for the year in which it was generated both for the case of retained earnings and for contributions made), as applicable.

Foreign currency translation differences which arise from the conversion of financial statements are recorded in the account “Foreign currency translation differences" within net shareholders' equity.

Foreign currency translation differences generated prior to January 1, 2009 have been transferred to the account “Reserves” in shareholders’ equity when the Company at the date of the first application of IFRS has invoked the exception included in IFRS 1 for the conversion of the financial statements prepared in accordance with generally accepted accounting principles in Chile to IFRS.

All balances and transactions between companies consolidated through global integration have been eliminated in consolidation.

(b)

Affiliated or associated companies

The affiliated or associated companies are all those entities on which significant influence is exercised but which are not controlled by the Company, which is, in general, accompanied by participation between 20% and 50% of voting rights. Investments in affiliated or associated companies are recognized in accounting using the equity method and are initially recognized at cost. The Group’s investment in affiliated or associated companies includes goodwill (net of any loss from accumulated impairment) identified in acquisition.

The participation in losses or gains subsequent to the acquisition of its affiliated or associated companies is recognized in income on an accrual basis and its participation in movements subsequent to the acquisition in reserves is recognized under Other reserves within Shareholders’ equity. When the participation in losses of an affiliated or associated company is equal to or greater than its participation in this affiliated or associated company no additional losses are recognized unless the company has incurred obligations or made payments in the name of the affiliated or associated company.

Unrealized gains from transactions with affiliated or associated companies are eliminated in consideration of the ownership percentage which the Company has on these. Unrealized losses are also eliminated except if the transaction provides evidence of loss from the impairment of the asset which is transferred.

(c)

Joint ventures

Joint ventures are contractual agreements by virtue of which the Company has agreed with other companies, outside the SQM Group, the performance of economic activities which are subject to joint control. As established in IAS 31 paragraph 38 the Company has adopted the equity method to recognize the participation in those entities jointly controlled.

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 of the 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 accounts receivable.

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 assignation of fair values in business combinations.

Although these estimates have been made in consideration of 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 (upwards or downwards) in the next few years, which would be prospective, recognizing the effects of change in estimates on the respective future 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 assign 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 geographic 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.

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

2.8

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 assets which qualify for these purposes, which are those which 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$5.756 as of March 31, 2010 and ThUS$3.132 as of March 31, 2009

2.	The present value of future costs, which the Company would have to be confronted with respect to the close of its facilities, are included in the asset's value at present value.

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 accounting withdrawal of substituted 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.

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

Classes of property, plant and equipment	Life or minimum rate		Life or maximum rate

Life or rate for buildings		3		80
Life or rate for plant and equipment		3		35

Life or rate for fixed facilities and accessories		3		35
Life or rate for motor vehicles		5		10
Life or rate for other property, plant and equipment		2		30

The gains or losses which are generated in the sale or withdrawal 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 annual licenses. Such license fees, 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 which are not from the Chilean State are recorded at their acquisition cost in property, plant and equipment.

2.9

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 assigned expenses. Subsequently, investment properties are stated at their acquisition cost less accumulated depreciation and the possible accumulated provisions for value impairment.

2.10

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 have 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 realizable value.

Accruals 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.

2.11

Trade accounts receivable and other accounts receivable

Trade accounts receivable and other accounts receivable 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 in their initial recognition as available-for-sale.

• Those through which the holder does not intend to partially recover substantially its entire investment for reasons other than credit impairment and, therefore, must be classified as available-for-sale.

These assets are initially recognized at their fair value (which is equivalent to their par 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. When the par value of the account receivable does not significantly differ from its fair value, it is recognized at par value. A provision for impairment loss is established for trade accounts receivable 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 accounts receivable.

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

Revenue recognition

Ordinary income includes the fair value of considerations received or considerations which will be received for the sale of goods and services during the course of the Company's activities. Ordinary income is presented netted against value added tax, returns, rebates and discounts and after the elimination of sales among subsidiaries.

Revenue is recognized when its amount can be stated in a reliable manner, it is possible that the future economic benefits 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 annual foreseen purchases and in accordance with the criteria defined in agreements.

(b)

Sales of services

Ordinary income associated with the provision of services is recognized considering the degree of completion of the service at the balance date provided that the result from the transaction can be estimated in a reliable manner.

(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.

2.13

Investments registered using the equity method

Participations in companies on 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. It is presumed that there is significant influence when the Company has participation which exceeds 20% of the investee's capital.

Under this method, the investment is recorded 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 percentage in the associated company. The associated goodwill acquired is included at the carrying value of the investment and it is not subject to amortization. The charge or credit to income reflects the proportional amount in the associated company's results.

Changes in shareholders’ equity of the associated companies are recognized proportionally with a charge or credit to “Other reserves” and classified according to their origin and, if applicable, these are disclosed in the Statement of changes in shareholders' equity.

The associated company’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 in accordance with the equity method was negative, participation is reflected as zero in the 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 participation value and proportional results recognized in conformity with their participation are included in the consolidated income statement accounts under “Participation income (loss) in companies using the equity method.”

2.14

Corporate tax

Corporate income tax for the year is determined as the addition of current tax from the different companies which is the result of the application of the type of tax on the taxable income for the year upon application of deductions which can be admitted for tax purposes plus the variation in deferred tax assets and liabilities and fiscal credits both for negative tax bases and deductions. 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 income taxes recoverable or Current income taxes payable, as applicable.

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

At the date of these statements of financial position, 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 participations 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 income.

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.

2.15

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.

2.16

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 decreased 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 costs of sales. 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 charge to income in the categories of expenses associated with the impaired asset function, except for properties reevaluated previously where the reevaluation was taken to equity. In this case impairment is also recognized with a charge to equity up to the amount of any previous reevaluation.

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 that is the case, the carrying value of the asset is increased at 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 income unless an asset is recorded at the reevaluated amount. Should this be the case, the reversal is treated as an increase in reevaluation.

The following criterion is also applied for an impairment assessment on specific assets:

2.17

Financial assets

SQM S.A. and subsidiaries classify their financial statements in the following categories: at fair value with changes in income, loans and accounts receivable, 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.

(a)

Financial assets at fair value with changes in income

Financial assets at fair value with changes in income are financial assets held for negotiation. 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 their negotiation unless they are designated as hedge accounting. Assets in this category are classified as current assets and variations generated in fair value are directly recognized in income.

(b)

Loans and accounts receivable

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 accounts receivable are included in “Trade accounts receivable and other accounts receivable” in the Statement of financial position and are stated at amortized cost.

(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 in equity those variations in fair value.

At each balance sheet date, the Company evaluates if there is objective evidence that a financial asset or a group of assets may have suffer impairment losses.

2.18

Financial liabilities

The Company classifies its financial liabilities in the following categories: at fair value with changes in income, trade accounts payable, loans that accrue interest or derivatives designated as hedging instruments.

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

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

(b)

Trade accounts payable

Balances payable to suppliers are subsequently stated in their amortized cost using the effective interest rate method.

(c)

Loans that accrue interest

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.

However, amounts of elements included in facilities, machinery and equipment destined to the same purpose are considered property, plant and equipment.

2.20

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 net income, except in the event that the Company has losses not absorbed in previous years.

2.21

Financial debt obligations

Financial debt obligations are recorded at their par value as non-current when their expiration date exceeds twelve months and as current when the expiration occurs in a period lower than that indicated above. Interest expenses are calculated in the year in which they are accrued following a financial criterion.

2.23

Consolidated statement of cash flows

Cash equivalents relate to short-term highly liquid investments which are easily converted into known amount of cash, are subject to low risk of change in their value and expire in less than three months.

For the purposes of preparing the statement of cash flows, cash and cash equivalents have been defined as cash and cash equivalents netted against pending bank overdrafts.

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 or outflows understanding as such those short-term highly-liquid investments with low risk of change in their value.

Operating activities: common activities related to the operation of the Group’s business as well as other activities which cannot be classified as investing or financing activities.

Investing activities: investing activities relate to the acquisition, disposition or disposal related to other long-term assets and other investments not included in cash and cash equivalents.

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. For the case of the United States, this is performed in accordance with the related pensions plan.

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 established obligations defined are directly recorded in net income.

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, 2010 and as of December 31, 2009.

2.25

Financial derivatives and hedging operations

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, it depends on the type of hedging, which may be as follows:

(a)

Fair value hedging of assets and liabilities recognized (fair value hedging);

(b)

Hedging of a single risk associated with an asset or liability recognized or a highly possible foreseen transaction (cash flow hedging);

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 9.3 (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 income.

(a)

Fair value hedging

The change in the fair value of a derivative is recognized with a charge or credit to income, 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 charge or credit to income.

Notes to the Interim Consolidated Financial Statements as of March 31, 2010

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 charge or credit to income at its fair value attributable to the risk that is being covered.

If the hedged entry is disposed of, the fair value not amortized is immediately recognized with a charge or credit to income.

(b)

Cash flow hedging

The cash portion of gains or losses from the hedging instrument is initially recognized with a charge or credit to shareholders’ equity whereas any non-cash portion is immediately recognized with a charge or credit to income, as applicable.

Amounts taken to equity are transferred to income when the hedged transaction affects income the same as when the hedged financial 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 taken to equity 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 shareholders' equity are transferred to income. If a hedging instrument expires, is sold, finished, exercised without any replacement or a rollover is performed or if its designation as hedging is revoked, amounts previously recognized in shareholders’ equity are maintained in shareholders' equity until the expected firm transaction or commitment occurs.

Lease

(a)

Leases - Financial lease

Leases are classified as financial leases when the Company has substantially all the risks and benefits derived from the property. Financial 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 payments made related to the lease.

Each lease payment is distributed between the liability and the debt obligations to obtain ongoing interest type on the debt pending balance. The respective lease obligations, netted against financial debt obligations, are included in other non-current liabilities. The interest element of financial cost is charged 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 financial 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 benefits derived from the ownership are classified as operating leases. Operating lease payments (netted against any incentive received from the lesser) are charged to the statement of comprehensive income or capitalized (as applicable) on a straight-line basis over the lease period.

The Company does not maintain any significant agreement which meets the conditions established in IAS 17 to be considered as financial leases and therefore, all the current agreements are considered operating leases.

Prospecting expenses

Those prospecting 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 Intangible 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 charged to income.

2.28

Other accruals

Accruals 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 accrual 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 income, the expense for any accrual is presented netted against any reimbursement.

Should the effect of the time value of money be significant, accruals 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 accrual over time is recognized as a financial 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 litigations in force, compensations or obligations, pending expenses the amount of which has not been determined , collaterals and other similar guarantees which are the responsibility of the Company. These are recorded at the time in which the responsibility or the obligation which determines the compensation or payment is generated.

Good and service insurance expenses

Payments for the different insurance policies which the Company contracts are recognized in expenses considering the proportional amount related to the time that they cover, regardless of payment terms. Amounts paid and not consumed are recognized as prepaid expenses within Current assets.

Costs of claims are recognized in income immediately after being known, netted against the recoverable amounts from insurance companies. Recoverable amounts are recorded as an asset reimbursable from the insurance company under “Trade accounts receivable and other accounts receivable", calculated as established in the respective insurance policies.

2.31

Intangible Assets

Intangible assets mainly relate to goodwill acquired, water rights, broadcasting rights, trademarks, rights of way related to electric lines and development expenses, and computer software licenses.

(a)

Goodwill acquired

Goodwill acquired represents the excess in acquisition cost on the fair value of them Company's ownership on the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to acquisitions of subsidiaries is included in intangible assets, which is subject to value impairment tests every time that the Company issues consolidated financial statements and is stated at cost plus 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. The assignation is performed based on cash generating units which are expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose.

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. These rights are presented under Intangible assets. Amounts paid are capitalized at the date of the agreement and charged to income according to the life of the right of way.

(d)

Computer software

Licenses for IT programs acquired are capitalized based on costs which have been incurred to acquire them and prepare them to use the specific program. 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 probably will generate economic benefits which are higher than costs during more than a year, are recognized as intangible assets. Direct costs include expenses incurred for employees who develop IT programs and an adequate percentage of general expenses.

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

2.32

Note 3 – First-time application of International Financial Reporting Standards (IFRS)

Application IFRS 1.

The annual consolidated financial statements for the Group as of December 31, 2010 will be the first consolidated financial statements prepared according to IFRS. The Company has applied IFRS 1 when preparing its interim consolidated financial statements.

The transition date is January 1, 2009, to which management has prepared its opening balance under IFRS to that date. The IFRS effective date is January 1, 2010, as indicated by the Chilean Superintendence of Securities and Insurance (SVS)

According to IFRS 1, in order to prepare the aforementioned consolidated financial statements, all mandatory exemptions have been applied by the Company, and some of the non-mandatory exemptions to the retroactive application of IFRS.

Exceptions established on IFRS 1 that the Company has decided to apply on its IFRS first time adoption process, are as follows:

i)	Business combinations

The Company has applied the exemption included in IFRS 1 for business combinations conducted from 2004 and thereafter. For these purposes, the Company reversed the amortization of goodwill recognized in accordance with the previous accounting standards.

ii)	Fair value or revaluation as attributable cost

The Company has chosen to measure certain property, plant and equipment items at their fair value at the transition date of January 1, 2009. The fair value of property, plant and equipment was measured through a business appraisal conducted by independent external experts, who determined the new historic initial values, useful lives and residual values of these assets.

iv)	Financial Instruments

The Company has defined the application of hedge accounting for financial derivative instruments associated with obligations with the public (bonds payable) denominated in UF and Chilean pesos as issued by the Company.

v)	Cumulative translation differences and technical revaluation

If the adopter uses this exemption: i) cumulative translation differences of all businesses abroad will be considered to be voided on the date of transition to IFRS; and ii) the gain or loss for the subsequent sale or disposal using another method of a business abroad will exclude translation differences which have arisen prior to the date of transition to IFRS and will include translation differences which have arisen subsequent to it.

The Company has opted to transfer cumulative translation differences and technical revaluation from other reserves to retained earnings. This exemption has been applied to all dependent companies in accordance with IFRS 1.

IFRS first-time adoption effects are recognized in retained earnings or other reserve accounts in the Company’s shareholders’ equity, depending on whether these adjustments represent realized or unrealized gains or losses at the transition date.

The following is a detailed description of the main differences between Generally Accepted Accounting Principles in Chile (Chilean GAAP) and International Financial Reporting Standards (IFRS) applied by the Company and the impact on shareholders’ equity as of March 31, 2009, and January 1, 2009 and on net income as of March 31,2010.

Note 3 – First-time application of International Financial Reporting Standards (IFRS), continued

Explanation of adjustments for the effects of transition to IFRS

The detail of the explanation of the different concepts enumerated in the reconciliation included in the preceding point is detailed as follows:

(a)	Deferred income taxes

As described in Note 2.15, under IFRS the Company has to recognize the effects of deferred income taxes for all temporary differences existing between the tax and book balance based on the liability method.

Although the method established in IAS 12 is similar to Chilean GAAP, the Company made the following adjustments in accordance with IFRS requirements:

The elimination of "deferred tax complementary accounts” in which the Company deferred the effects on shareholders’ equity of the first-time application of Technical Bulletin No. 60 issued by the Chilean Association of Accountants amortized with a charge / credit to income in the foreseen term for the reversal of the difference (or consumption of the related tax loss, if this is the case.)

ii)

The determination of deferred taxes on entries not subject to the calculation under Chilean GAAP but which qualify as temporary differences under IFRS and the calculation of the tax effect of transition adjustments to IFRS.

(b)	Revaluation of property, plant and equipment at fair value as attributed cost

Chilean GAAP establish the valuation of property, plant and equipment at acquisition cost restated for inflation less accumulated depreciation and accumulated impairment losses and do not allow property, plant and equipment revaluation (revaluations were only and extraordinarily authorized by the Chilean SVS in accordance with Circulars Nos. 550 and 566 of 1985 issued by the Chilean Superintendence of Securities and Insurance.) Except for that indicated in the next paragraph, the Company has considered the values of assets determined in accordance with the aforementioned accounting standards, as attributed cost of its property, plant and equipment.

Notes to the Interim Consolidated Financial Statements as of March 31, 2010

Note 3 – First-time application of International Financial Reporting Standards (IFRS), continued

For the adoption of IFRS, the Company valued certain property, plant and equipment items (mainly machinery and equipment) at their fair value in conformity with the exemption contained in IFRS 1. The revaluation was performed only once in accordance with IFRS 1. The new value determined relates to the initial cost of the asset beginning on the transition date. This fair value of assets amounted to ThUS$60,458 as of January 1, 2009 and represented an adjustment to shareholders’ equity (decrease) of ThUS$54,366 at that date.

(c)	Minimum Dividend

In accordance with Chilean GAAP, dividends for distribution are recorded in the Company’s financial statements at the time of the agreement at the Shareholders’ or Board of Directors’ Meeting. Law No. 18,046 on Shareholders' Companies establishes in its article No. 79 that public shareholders' companies will have to distribute as dividends to its shareholders, at least, 30% of net income for the year, unless the shareholders of shares issued with voting right at the Shareholders' Meeting unanimously agree otherwise. Under IFRS, the Company has recorded the obligation on an accrual basis, net of provisional dividends which would have been agreed at the closing date for 30% of net income for the year, which is the legal minimum percentage. As of December 31, 2009, the provisional dividend distributed during November covers this minimum dividend and therefore, no accrual was required.

(d)	Minority interest

Chilean GAAP, applied for the preparation of the consolidated financial statements recognized the participation of minority shareholders in the shareholders’ equity of subsidiaries as a separate account between liabilities and net shareholders’ equity of the Company’s consolidated financial statements. Likewise, the consolidated financial statements for the year under Chilean GAAP excluded through a specific line the participation of minority interest in net income of subsidiaries. Under IFRS, minority shareholders are a part of the economic conglomerate or Group and; therefore, their participations are considered part of the statement of changes in net shareholders’ equity and the statement of comprehensive income.

(e)	Hedging through derivatives

The Company maintains as hedging instruments those financial derivatives associated with obligations with the public (bonds payable) issued in UF and in Chilean pesos. Under IFRS, changes generated in the fair value of derivatives which are designated and qualified as hedging, for their cash component, are recognized in net shareholders’ equity. The gain or loss relative to the non-cash part of the hedging is immediately recognized in the statement of comprehensive income under "Other gains / losses." This represents a change with respect to Chilean GAAP where realized gains or losses for this concept were recognized in non-operating income whereas unrealized gains or losses related to changes in fair values of derivative instruments in cash flow hedging were deferred in asset and liability accounts without affecting income up to the settlement of hedged and hedging entries.

(f)	Actuarial staff severance indemnities

IFRS require that the benefits of services defined delivered to employees at long-term are determined in consideration of the application of an actuarial calculation model generating differences with respect to the methodology applied previously which considered present values.

(g)	Negative goodwill

IFRS do not contemplate the recording in the balance sheet of negative goodwill at the date of a business combination recognizing this difference directly on income (under Chilean GAAP this was presented deducting assets.) Accordingly, the existing balance for this concept was transferred to the Reserve for Retained Earnings account within Shareholders' Equity.

(h)

Goodwill

Under IFRS, the Company has considered goodwill as an intangible asset of indefinite useful life. At least, once a year, the cash generating unit which gave rise to goodwill is assessed for possible impairment. If there is any evidence of impairment, goodwill is initially adjusted with a charge to income. For first-time adoption purposes, the Company opted to reverse the amortization of goodwill which was generated by acquisitions of companies recorded using the business combination method conducted beginning in 2004. No other effects were generated for these restatements.

(i)	Reconciliation of the cash flows for the year ended December 31, 2009

The main differences between Chilean GAAP and IFRS in the preparation of the statement of cash flows relate to the classification of financial lease installments, which are included as investing activities in accordance with Chilean GAAP and as financing activities under IFRS.

Note 4 – Financial Risk Management

4.1 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 objective of financial risk management activities is safeguarding the Company and its subsidiaries’ financial stability and sustainability at all times both under usual and exceptional conditions.

Our operations are subject to certain risk factors that may affect SQM’s financial condition or results of operations.

These risks are not the only ones we face. Additional risks of which we are not currently aware but which we believe are not significant may also affect our commercial operations, our business, the financial position or the results of operations may be materially affected by any of these risks.

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

4.2 Risk Factors

4.2.1. Market risk

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

Our sales to emerging markets expose us to risks related to economic conditions and trends in those countries

The volatility of world prices of fertilizers and chemical products and changes in production capacities might affect our business, financial position and results of operations.

Our inventory levels may increase due to the global economic situation.

Quality standards in markets in which we sell our products may be more strict throughout time

High prices of raw materials and energy may increase our production costs and the costs of goods sold

4.2.2 Bad debt risk

Our risk level and exposure to uncollectible accounts receivable (bad debt) may increase significantly depending on the present economic situation. Although we take actions to minimize the risk of losses due to uncollectible accounts, such as the use of credit insurance, letters of credit and prepayments for a portion of our accounts receivable, a substantial increase in these losses may have a material adverse effect on our business, financial position and results of operations.

The current economic contraction and its potentially 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.

4.2.3

Exchange rate risk

Exchange rate fluctuations may have a material impact on our financial results.

The Chilean peso has been subject to large devaluations and revaluations in the past and may be subject to significant fluctuations in the future. We trade a significant part of our business in U.S. dollars and U.S. dollar is the currency of the main economic environment where we operate and is our functional currency for financial statement reporting purposes. However, a significant part of our costs relates to Chilean peso. Therefore, an increase or a decrease in the exchange rate between Chilean peso and U.S. dollar would affect our production costs. As of March 31, 2010, the exchange rate was Ch$524.46 per US$1.00 and as of December 31, 2009, the exchange rate was Ch$507.10 per US$1.00.

In addition, given that we are an international company which operates in Chile and in several other countries, we trade a part of our business and have assets and liabilities in Chilean pesos and other currencies which are different from U.S. dollars. Therefore, fluctuations in the exchange rate of such foreign currencies may affect our business, financial position and results of operations.

With respect to debt denominated in a currency other than U.S. dollar, the Company has taken hedging in the form of currency swaps to eliminate the exchange rate risk.

4.2.4

Interest rate risk

Interest rate fluctuations may have a material impact on our financial results.

We maintain short and long-term debt stated at Libor plus a spread. As we do not have derivative instruments to hedge the Libor, we are subject to fluctuations in this rate. As of March 31, 2010, we had approximately 45% of long-term financial debt valued at LIBOR and; therefore, significant increases in the rate may have an impact on our financial position.

4.2.5

Liquidity risk

The liquidity risk is related to fund needs to deal with payment obligations. The Company’s objective is maintaining a balance between fund continuity and financial flexibility through normal operating flows, bank loans, public bonds, short-term investments, marketable securities.

We have an ambitious capital expenditure program, which is subject to significant risks and uncertainties. Specifically, reserve exploration and exploitation, mining costs and processing costs, the maintenance of machinery and equipment and compliance with laws and standards applicable require substantial capital expenditures. We must continue investing capital to maintain or increase our exploitation levels and the amount of finished products which we produce. We require environmental licenses for our new projects. Obtaining licenses, in certain cases, may generate significant delays in the execution and implementation of these new projects and; consequently, may require that we reassess the respective risks and economic incentives. We cannot ensure that we could maintain our production levels or generate sufficient cash flows or that we will have access to investments, loan or other financing alternatives which are sufficient to continue our exploration, exploitation and refining activities in or over the present levels or that we will be able to implement our projects or receive the licenses required for them on a timely basis. Any or all these factors may have a material adverse impact on our business, financial position and results of operations.

4.3	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 8 - Information to be disclosed on related companies

8.1	Information to be disclosed on related companies

Balances pending at year-end are not guaranteed, accrue no interest and are settled in cash. No guarantees have been delivered or received for accounts receivable from or payable to related parties. For the period ended March 31, 2010, the Group has not recorded any impairment in accounts receivable 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.

8.2	Relationships between the controlling interest 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 32% 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 2.07% 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 SQMS.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 9 - Financial Instruments, 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. Hedging is 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.

16.2	Defined benefit plan policy

This policy is applied to all benefits 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.

Staff severance indemnities

The Company only provides compensation and benefits to active employees.

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 net income at the end of each period applying a factor obtained subsequent to the employee appraisal process.

The bonus provided to the Company’s directors is calculated based on net income at each year-end and will consider the application of a percentage factor.

The benefit relates to vacations (short-term 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.

Note 16 Accrued Liabilities and Employee Benefits, continued

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 14, 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.

All benefits provided by the company are current. Certain benefits such as vacation and severance indemnities are long-term benefits which are accumulative. These relate to services provided in which there are future disbursements which will be subsequent to twelve months

16.3	Other Long-term Benefits

The other long-term benefits relate to staff severance indemnities and are recorded at their actuarial value.

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.

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-2004 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.

SQM S.A. and its subsidiaries have been participating and probably will continue to participate habitually as plaintiffs or defendants in various judicial proceedings that have been and will be filed and are subject to the decisions of the Ordinary Courts of Justice. Those proceedings, which are regulated by the applicable legal provision, mainly seek to exercise or oppose certain actions or exceptions related to certain mining concessions constituted or in the process of being constituted and do not and will not essentially affect the development of SQM S.A. and its subsidiaries.

Soquimich Comercial S.A. has been participating and probably will continue to participate habitually as a plaintiff in various judicial proceedings through which it seeks mainly to collect and receive the amounts owed to it. As of December 31, 2009 in the total amount claimed in such proceedings is approximately ThUS $900.

SQM S.A. and its subsidiaries have tried and currently continue to try to obtain payment of certain amounts still owed to them for their normal business activities. Those amounts will continue to be judicially and non-judicially demanded by the plaintiffs and the actions exercised in relation to them are currently in full force.

SQM S.A. and its subsidiaries have not been legally notified of other complaints other than those listed above and which pursue the voidance of certain mining properties purchased by SQM S.A. and its subsidiaries and whose proportional purchase price, in respect to the part affected by the respective overlap, exceeds the nominal and approximate amount of ThUS$150 or which seek to obtain payment of certain amounts allegedly owed from exercising their own activities and which exceed the nominal individual amount of approximately ThUS$1 50.

Note 24 – The Environment

24.1	Information to be disclosed 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.

In the Maria Elena location, this particle material affects air quality exceeding the allowed standard for PM 10. Within the framework of a decontamination plan for this city and in accordance with its Sustainable Development Policy, the Company has implemented a series of measures that have shown notable improvement in air quality at Maria Elena. This project is operating from January 2009 having achieved the final closure of the old crushing plant located in Maria Elena beginning on July 5, 2008 with the related improvement in air quality.

In addition, for all its operations, 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.

28.4	Current and deferred income taxes

Assets and liabilities recognized in the Statement of Financial Position are offset when and only if:

1. the Company has legally recognized before the tax authority the right to offset the amounts recognized in these entries; and

deferred income tax assets and liabilities are derived from income tax related to the same tax authority on:

(i)

the same entity of tax subject; or

(ii)

different entities or subjects to tax effects who intend either to settle current fiscal assets and liabilities for their net amount, either realize assets and pay liabilities simultaneously in each of the future periods in which the Company expects to settle or recover significant amounts of deferred tax assets or liabilities.

Deferred income tax assets recognized are those income taxes to be recovered in future periods, related to:

(a) deductible temporary differences;

(b) the compensation of losses obtained in prior periods, which have not yet been subject to tax deduction; and

The Company recognizes a deferred tax asset when there is certainty that these can be offset with fiscal income from subsequent periods, losses or credits.

Fiscal amounts not yet used but solely as long as it is possible that there will be tax earnings in the future to charge to these losses or unused fiscal credits against them.

Deferred tax liabilities recognized are the amounts of income taxes payable in future periods related to taxable temporary differences.

d.10	Explanation of the relationship between expense (income) for taxes and accounting income

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.)

d.11	Tax periods potentially subject to verification:

The Group companies are potentially subject to tax audits for income taxes by tax authorities in each country. These audits are limited to a number of annual tax periods, which, in general, when they elapse, give rise to the expiration of these inspections.

Tax audits, due to their nature, are often complex and may require several years. Below, we provide a summary of tax periods which are potentially subject to verification, in accordance with tax regulations in force in the country of origin:

Chile

In Chile, the tax authority may review tax returns of up to 3 years old from the expiration date of the legal term in which the payment should have been made. In the event that there is an administrative or legal notice, the review can be extended to a period of 6 years.

United States

In the United States the tax authority may review tax returns of up to 3 years old from the expiration date of the tax return. In the event of detecting an omission or error in the tax return of revenue or cost of sales, the review can be extended up to a period of 6 years.

Mexico:

In Mexico, the tax authority can review tax returns up to 5 years old from the expiration date of the tax return.

Spain:

In Spain, the tax authority can review tax returns up to 4 years old from the expiration date of the tax return.

Belgium:

In Belgium, the tax authority may review tax returns of up to 3 years old, from the expiration date of the tax return if no tax losses exist. In the event of detecting an omission or error in the tax return, the review can be extended up to a period of 5 years.

South Africa:

In South Africa, the tax authority may review tax returns of up to 3 years old, from the expiration date of the tax return. In the event of detecting an omission or error in the tax return, the review can be extended up to a period of 5 years.
