## 3) DESCRIPTION OF BUSINESS ENVIRONMENT

## 3) A) DESCRIPTION OF BUSINESS ENVIRONMENT: HISTORICAL INFORMATION

Commercial exploitation of the caliche ore deposits in northern Chile began in the 1830s, when sodium nitrate was extracted from the ore for use in the manufacturing of explosives and fertilizers. By the end of the nineteenth century, nitrate production had become the leading industry in Chile, and the country was the world’s leading supplier of nitrates. The accelerated commercial development of synthetic nitrates in the 1920s and the global economic depression in the 1930s caused a serious contraction of the Chilean nitrate business, which did not recover significantly until shortly before the Second World War. After the war, the widespread commercial production of synthetic nitrates resulted in a further contraction of the natural nitrate industry in Chile, which continued to operate at depressed levels into the 1960s.

We were formed in 1968 through a joint venture between Compañía Salitrera Anglo Lautaro S.A. (“Anglo Lautaro”) and the Production Development Corporation (Corporación de Fomento de la Producción or “Corfo”), a Chilean government entity. Three years after our formation, in 1971, Anglo Lautaro sold all of its shares to Corfo, and we were wholly owned by the Chilean Government until 1983. In 1983, Corfo began a process of privatization by selling our shares to the public and subsequently listing such shares on the Santiago Stock Exchange. By 1988, all of our shares were publicly owned. Our Series B ADSs have traded on the NYSE under the ticker symbol “SQM” since 1993. We accessed international capital markets again for the issuance of additional ADSs in 1995 and 1999. On December 21, 2006, two groups of shareholders, the “Pampa Group” (which includes the company Sociedad de Inversiones Pampa Calichera S.A. and its related companies, Inversiones Global Mining Chile Limitada and Potasios de Chile S.A.) and Kowa Group (which includes the companies Kowa Company Ltd., Inversiones La Esperanza (Chile) Limitada, Kochi S.A and La Esperanza Delaware Corporation) signed a joint agreement and became the controlling group of SQM.

Since our inception, we have produced nitrates and iodine, which are obtained from the caliche ore deposits in northern Chile. In 1985, we began to use heap leaching processes to extract nitrates and iodine, and in 1986 we started to produce potassium nitrate at our Coya Sur facility. Between 1994 and 1999, we invested approximately US$300 million in the development of the Salar de Atacama project in northern Chile, which enabled us to produce potassium chloride, lithium carbonate, potassium sulfate and boric acid.

From 2000 through 2004, we principally consolidated the investments carried out in the preceding five years. We focused on reducing costs and improving efficiencies throughout the organization. In addition, in 2001, we signed a commercial distribution agreement with the Norwegian company Yara International ASA, in order to take advantage of cost synergies in the Specialty Plant Nutrition business line.

Starting in 2005, we began strengthening our leadership position in our core businesses through a combination of capital expenditures and advantageous acquisitions and divestitures. Our acquisitions have included the Kemira Emirates Fertiliser Company (“Kefco”) in Dubai in 2005 and the iodine business of Royal DSM N.V. (“DSM”) in 2006. We also entered into a number of joint ventures, including a joint venture with Miga Corporation (“Miga”), signed in 2008, for the production of potassium nitrate, and SQM VITAS, our joint venture with the French Roullier Group. Pursuant to the latter joint venture, in 2010, we launched a new line of soluble phosphate products, and in 2012 we built new plants for the production of water-soluble fertilizers in Brazil (Candeias), Peru and South Africa (Durban). We have also sold: (i) Fertilizantes Olmeca, our former Mexican subsidiary, in 2006, (ii) our stake in Impronta S.R.L., our former Italian subsidiary, in 2007 and (iii) our former butyllithium plant located in Houston, Texas, in 2008. These sales allowed us to concentrate our efforts on our core products.

The capital expenditure program has allowed us to add new products to our product lines and increase the production capacity of our existing products. In 2005, we started production of lithium hydroxide at a



plant in the Salar del Carmen, near the city of Antofagasta in the north of Chile. In 2007, we completed the construction of a new prilling and granulating plant. In 2011, we completed expansions of our lithium carbonate capacity, achieving 48,000 metric tons of capacity per year. Since 2010, we have continued to expand our production capacity of potassium products in our operations in the Salar de Atacama. In 2011, we completed the construction of a new potassium nitrate facility in Coya Sur, increasing our overall production capacity of potassium nitrate by 300,000 metric tons per year. In 2013, we completed expansions in the production capacity of our iodine plants in Nueva Victoria. Our capital expenditure program also includes exploration for metallic minerals. Our exploration efforts have led to discoveries that in some cases may result in sales of the discovery and the generation of royalty income in the future. Within this context, in 2013 we sold our royalty rights to the Antucoya mining project to Antofagasta Minerals. In 2013 we also opened a trading office in Thailand.

In 2014, we invested in the development of new extraction sectors and production increases in both nitrates and iodine at Nueva Victoria, reaching an approximate production capacity (including the Iris facility) of 8,500 metric tons per year of iodine at the facility. We also issued a bond in the international capital markets for US$250 million, primarily to refinance existing indebtedness.

In 2015, we focused on increasing the efficiency of our operations. Within this context, we announced a plan to restructure our iodine and nitrate operations. In an effort to take advantage of our highly efficient production facilities at our Nueva Victoria site, we decided to suspend the mining and nitrate operations and reduce iodine production at our Pedro de Valdivia site. During the year, we increased our iodine production capacity at Nueva Victoria to approximately 9,000 metric tons per year.

In 2015, we focused on increasing the efficiency of our operations. Within this context, we announced a plan to restructure our iodine and nitrate operations. In an effort to take advantage of our highly efficient production facilities at our Nueva Victoria site, we decided to suspend the mining and nitrate operations and reduce iodine production at our Pedro de Valdivia site. During 2017, we increased our iodine production capacity at Nueva Victoria to approximately 10,000 metric tons per year. We continued expanding in 2018, and today, including Pedro de Valdivia and Nueva Victoria, our current effective iodine capacity is approximately 14,000 metric tons per year.

In 2016, we entered into a 50/50 joint venture with Lithium Americas to develop the Minera Exar lithium project in Caucharí-Olaroz in the Jujuy province of Argentina. We also made a capital contribution of US$20 million to Elemental Minerals Limited (“Elemental Minerals”), an Australian based company whose main assets are various potassium deposits in the Republic of Congo. We invested approximately US$20 million in exchange for 18% of the company, and a right of first refusal for approximately 20% of the total potash production of Elemental Minerals. Following this transaction at the end of 2016, Elemental Minerals changed its name to Kore Potash Limited. The State General Reserve Fund of Oman contributed US$20 million. These investments are not included in the capital expenditure program amounts discussed in the section below. These investments were carried out with internal financing. In 2018, SQM Potasio sold to Ganfeng Lithium Netherlands Co., BV (Ganfeng) its entire shareholding and irrevocable contributions in the Minera Exar project joint venture (“Exar”). Exar has paid SQM Potasio all outstanding loans it received from the company; and Exar has paid SQM for the services rendered to Exar during the project’s development stage. SQM received cash of US$87.5 million for its joint venture interest in Exar, and Gangfeng is responsible for a US$50 million deferred payment to SQM if certain sales goals are met by the project.

In 2017, we continued to expand our operations outside Chile and, together with our subsidiary SQM Australia Pty, acquired 50% of the assets of the Mount Holland lithium project in Western Australia, Australia. We entered into a 50/50 joint venture with Kidman Resources Limited (“Kidman”) to develop mining operations and construct concentration and refining plants to produce 45,000 metric tons per year of lithium, starting in 2021. Kidman will retain the exclusive right to exploit gold within the project area. According to the agreement, SQM Australia Pty committed to pay a price of US$35 million, subject to



compliance with conditions established in the agreement. SQM Australia is also obligated to make capital contributions to the project of (i) US37.5 million on behalf of Kidman of which US7.5 million has already been paid, leaving the balance subject to the satisfaction of certain conditions, and (ii) US37.5 million on its behalf, of which it has already contributed US7.5 million, leaving the balance subject to the satisfaction of certain conditions. In 2018, we paid Kidman the remaining balance, as a result of the conditions being satisfied, and as outlined in the 2017 agreement.

On December 13, 2018, the Minister for Mines and Petroleum in Western Australia granted Kidman the exemption from relevant expenditure requirements in relation to mining tenements of the Mount Holland project that were subject to exemption objections.

## ii) COMPETITION AND MARKET SHARE

See section 3) C) Description of Business Environment: Activities and Businesses.

## iii) LEGAL FRAMEWORK

## Government Regulations

## Regulations in Chile Generally

We are subject to the full range of government regulations and supervision generally applicable to companies engaged in business in Chile, including labor laws, social security laws, public health laws, consumer protection laws, tax laws, environmental laws, free competition laws, securities laws and anti-trust laws. These include regulations to ensure sanitary and safety conditions in manufacturing plants.

We conduct our mining operations pursuant to judicial exploration concessions and exploitation concessions granted pursuant to applicable Chilean law. Exploitation concessions essentially grant a perpetual right (with the exception of the Salar de Atacama rights, which have been leased to us until 2030) to conduct mining operations in the areas covered by such concessions, provided that annual concession fees are paid. Exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time, and to subsequently request a corresponding exploitation concession.

Under Law No. 16,319 that created the Chilean Nuclear Energy Commission (Comisión Chilena de Energía Nuclear or “CCHEN”), we have an obligation to the CCHEN regarding the exploitation and sale of lithium from the Salar de Atacama, which prohibits the use of lithium for nuclear fusion. In addition, CCHEN has imposed annual quotas that limit the total tonnage of lithium authorized to be sold.

We also hold water use rights granted by the respective administrative authorities and which enable us to have a supply of water from rivers or wells near our production facilities sufficient to meet our current



operating requirements. See section 3) E) Description of Business Environment: Risk Factors. The Water Code and related regulations are subject to changes, which could have a material adverse impact on our business, financial condition and results of operations.

We operate port facilities at Tocopilla, Chile for the shipment of products and the delivery of raw materials in conformity with maritime concessions, which have been granted by the respective administrative authority. These concessions are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

In 2005, Law No. 20,026, known as the Law to Establish a Specific Tax on Mining Activity” (Ley que Establece un Impuesto Específico a la Actividad Minera or the “Royalty Law”), established a royalty tax to be applied to mining activities developed in Chile. In 2010, modifications were made to the law and taxes were increased.

In 2012, new modifications to the tax laws were enacted to set the corporate tax rate at 20% for companies like SQM.

On September 29, 2014, Law No. 20,780 was published (the “Tax Reform”), introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. As a result of these reforms, open stock corporations, like SQM, are subject to the partially integrated shareholder tax regime (sistema parcialmente integrado). The corporate tax rate applicable to us increased gradually from 20% to 25.5% in 2017, and to the maximum rate of 27% in 2018.

The Tax Reform tax increase prompted a US$52.3 million increase in our deferred tax liabilities as of December 31, 2014. In accordance with IAS 12, the effects generated by the change in the income tax rate approved by the Tax Reform on income and deferred taxes were applied to the income statement. For purposes of the Company’s statutory consolidated financial statements filed with the CMF, in accordance with the instructions issued by the CMF in its circular 856 of October 17, 2014, the effects generated by the change in the income tax rate were accounted for as retained earnings. The amount charged to equity as of December 31, 2014 was US$52.3 million, thereby giving rise to a difference of US$52.3 million in profit for the year and income tax expense as presented in the Company’s 2014 audited consolidated financial statements in its annual report on Form 20-F compared with profit and income tax expense as presented in the Company’s 2014 statutory consolidated financial statements filed with the CMF.

The Chilean government may again decide to levy additional taxes on mining companies or other corporations in Chile, and such taxes could have a material adverse impact on our business, financial condition and results of operations.

We are also subject to the Chilean Labor Code and the Subcontracting Law, which are overseen by the Labor Authority (Dirección del Trabajo), the National Geology and Mining Service (Servicio Nacional de Geología y Minería or “Sernageomin”), and the National Health Service. Recent changes to these laws and their application may have a material adverse effect on our business, financial condition and results of operations. See “Section 3E. Description of Business Environment: Risk Factors – We are exposed to labor strikes and labor liabilities that could impact our production levels and costs”.

In addition, we are subject to Law No. 20,393, which establishes criminal liability for legal entities, for the crimes of (a) asset laundering, (b) financing terrorism and (c) bribery. Potential sanctions for violations under this law could include (i) fines, (ii) loss of certain governmental benefits during a given period, (iii) a temporary or permanent bar against the corporation executing contracts with governmental entities, and (iv) dissolution of corporation.



Finally, we are governed by the Securities Law and Law No. 18,046 on Corporations (Ley de Sociedades Anónimas or the “Chilean Corporations Act”), which regulates corporate governance. Specifically, the Chilean Corporations Act regulates, among other things, independent director requirements, disclosure obligations to the general public and to the CMF, as well as regulations relating to the use of inside information, the independence of external auditors, and procedures for the analysis of transactions with related parties.

There are currently no material legal or administrative proceedings pending against us except as discussed in Note 22.1 to our Consolidated Financial Statements and below under “Safety, Health and Environmental Regulations in Chile,” and we believe we are in compliance in all material respects with all applicable statutory and administrative regulations with respect to our business.

## Safety, Health and Environmental Regulations in Chile

Our operations in Chile are subject to both national and local regulations related to safety, health and environmental protection. In Chile, the main regulations on these matters that are applicable to us are the Mine Health and Safety Act of 1989 (Reglamento de Seguridad Minera or the “Mine Health and Safety Act”), the Health Code (Código Sanitario), the Health and Basic Conditions Act of 1999 (Reglamento sobre Condiciones Sanitarias y Ambientales Básicas en los Lugares de Trabajo or the “Health and Basic Conditions Act”), the Subcontracting Law and the Environmental Law of 1994, amended in 2010 (Ley sobre Bases Generales del Medio Ambiente or the “Environmental Law”).

Health and safety at work are fundamental aspects in the management of mining operations, which is why we have made constant efforts to maintain good health and safety conditions for the people working at our mining sites and facilities. In addition to the role played by us in this important matter, the Chilean government has a regulatory role, enacting and enforcing regulations in order to protect and ensure the health and safety of workers. The Chilean government, acting through the Ministry of Health and the Sernageomin, performs health and safety inspections at the mining sites and oversees mining projects, among other tasks, and it has exclusive powers to enforce standards related to environmental conditions and the health and safety of the people performing activities related to mining.

The Mine Health and Safety Act protects workers and nearby communities against health and safety hazards, and it provides for enforcement of the law where compliance has not been achieved. Our Internal Mining Standards (Reglamentos Internos Mineros) establish our obligation to maintain a workplace where safety and health risks are managed appropriately. We are subject to the general provisions of the Health and Basic Conditions Act, our own internal standards and the provisions of the Mine Health and Safety Act. In the event of non-compliance, the Ministry of Health and particularly the Sernageomin are entitled to use their enforcement powers to ensure compliance with the law.

In November 2011, the Ministry of Mining enacted Law No. 20,551 that Regulates the Closure of Mining Sites and Facilities (Ley que Regula el Cierre de Faenas e Instalaciones Mineras). This statute entered in force in November 2012 and required all mining sites to present or update their closure plans as of November 2014. SQM has fulfilled this requirement for all of its mining sites and facilities. The main requirements of the law are related to disclosures to the Sernageomin regarding decommissioning plans for each mining site and its facilities, along with the estimated cost to implement such plans. The mining site closure plans are approved by Sernageomin and the corresponding financial assurances are subject to approval by the CMF. In both cases, SQM has received the requisite approvals.

The new and modified Chilean Environmental Law defines the Ministry of the Environment as the governmental agency responsible for coordinating and supervising environmental issues. The Environmental Assessment Service is responsible for reviewing environmental assessments of new projects or significant modifications of existing ones, and the decision to grant or reject environmental permits rests with the Environmental Assessment Commission. On the other hand, the Superintendence



for the Environment is responsible for supervising environmental performance during the construction, operation and closure of the projects that have been evaluated for environmental permits, and it is also responsible for enforcing compliance with prevention and atmospheric decontamination plans. The Environmental Law also promotes citizen participation in project evaluation and implementation, providing more opportunities for observations or objections to be made during the environmental evaluation process. Annually, the Superintendence for the Environment audits a sample of approved projects to verify compliance with the environmental permits, and it may pursue fines or sanctions if applicable, which can be challenged in the Environmental Court.

We continuously monitor the impact of our operations on the environment and on the health of our employees and other persons who may be affected by such operations. We have made modifications to our facilities in an effort to eliminate any adverse impacts. Also, over time, new environmental standards and regulations have been enacted, which have required minor adjustments or modifications of our operations. We anticipate that additional laws and regulations will be enacted over time with respect to environmental matters. There can be no assurance that future legislative or regulatory developments will not impose new restrictions on our operations. We are committed to continuously improving our environmental performance through our Environmental Management System (“EMS”), voluntary evaluations, such as Ecovadis, and international certifications, such as the Responsible Conduct certification from the Chilean Industrial Chemicals Association, which applies to our operations at Nueva Victoria, and the Protect&Sustain certification from the International Fertilizer Association, which applies to our operations at Coya Sur, the Salar de Atacama, Tocopilla, Antofagasta and Santiago.

We have submitted and will continue to submit several environmental impact assessment studies related to our projects to the governmental authorities. We require the authorization of these submissions in order to maintain and to increase our production capacity.

## International Regulations

We are subject to complex regulatory requirements in the various jurisdictions in which we operate, including the following:

At the end of 2018, the European Parliament, the Council of Member States of the European Union and the European Commission agreed to a new regulation for fertilizers. The new European regulation reduces the maximum content limit of perchlorates in inorganic fertilizer with macronutrients, such as the potassium nitrate sold by us, to 0.005%. In addition to this limit, the regulation incorporates maximum levels of other pollutants, such as heavy metals, and establishes a new procedure – called a conformity assessment – to be undertaken prior to the commercialization of fertilizers in Europe. The fertilizers that we sell contain less than 0.005% of perchlorate; however, the Food Chain Security unit of the General Health and Consumer Affairs Council initiated a revision of the perchlorate limits in food that have been in force and effect since June 2015, following the European Food Safety Authority’s (“EFSA”) evaluation of human exposure to perchlorate in food and in drinkable water. We expect a new definition of the new limits of perchlorates in food in the near term.

Under the requirements of Regulation (EC) No. 1907/2006, the records of potassium nitrate and sodium nitrate were updated according to the latest format IUCLID. In turn, during the year 2018, ten new registrations were made corresponding to the substances sold by our new subsidiary SQM International. The strategy for the implementation of the requirements of the Article 45 of Regulation (EC) No. 1272/2008 was defined, under which the Toxicological Information Centers must be informed about the composition of hazardous mixtures prior to their commercialization. For this implementation, an internal numerical code was developed for the identification of all the fertilizer mixtures sold by SQM Europe and SQM Iberian.



In August 2017, United States Environmental Protection Agency (“US-EPA”) published the Inventory Notification (Active-Inactive) Requirements regulation under the Toxic Substances Control Act which established that as of February 7, 2018, SQM North America Corp. must provide information with respect to all chemical substances imported into the United States during 2006-2016. In January 2018, this notification was made, and all substances sold are listed as active, which has been reported to customers who have requested it. In the United States, SQM North America re-certified before the Organic Materials Review Institute all products sold by it in this market.

In South Korea, SQM registered sodium nitrate under the K-REACH standard, using an Exclusive Representative to facilitate the regulatory compliance of our customers in this market. At the end of December 2018, an amendment to the K-REACH regulation was passed, pursuant to which all chemical substances are subject to registration. SQM is evaluating the regulatory change, which applies to four SQM products currently sold in South Korea, establishing the necessary alliances to facilitate compliance with this new requirement, which considers as a first stage a pre-notification in June 2019.

On August 8, 2018, Normative Instruction No. 39 became effective in Brazil, establishing definitions, requirements, specifications, guarantees, product registrations, authorizations, packaging, fertilizer product labels, mineral fertilizer tolerances, among others, repealing Normative Instruction No. 46 of 2016 and defining new requirements for exports to Brazil.

During 2018, the Ecuadorian Agricultural Quality Assurance Agency (AGROCALIDAD) made two modifications (resolutions 031 of March 2018 and 0218 of December 2018) to the general regulations for the registration and control of fertilizers. As a result of both modifications, SQM Ecuador had to adapt its fertilizer registration and labeling processes.

The opening of SQM Colombia during 2018 opened a new challenge for the processing of new fertilizer registrations. Currently, eight products are registered and work is being done on the definition of all the new products to be registered.

On October 9, 2018, NOM-018-STPS-2015 on the Harmonized System for the identification and communication of hazards and risks by hazardous chemical substances in the workplace came into effect in Mexico. SQM Mexico has implemented this regulation in all its productive tasks, in the Safety Data Sheets and in the labeling of applicable products.

## 3) C) DESCRIPTION OF BUSINESS ENVIRONMENT: ACTIVITIES AND BUSINESSES

## The Company

We believe that we are the world’s largest producer of potassium nitrate and iodine. We also produce specialty plant nutrients, iodine derivatives, lithium and its derivatives, potassium chloride, potassium sulfate and certain industrial chemicals (including industrial nitrates and solar salts). Our products are sold in over 110 countries through our worldwide distribution network, with 92% of our sales in 2018 derived from countries outside Chile.

Our products are mainly derived from mineral deposits found in northern Chile. We mine and process caliche ore and brine deposits. The caliche ore in northern Chile contains the only known nitrate and iodine deposits in the world and is the world’s largest commercially exploited source of natural nitrates. The brine deposits of the Salar de Atacama, a salt-encrusted depression in the Atacama Desert in northern Chile, contain high concentrations of lithium and potassium as well as significant concentrations of sulfate and boron.

From our caliche ore deposits, we produce a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, we



extract brines rich in potassium, lithium, sulfate and boron in order to produce potassium chloride, potassium sulfate, lithium solutions and bischofite (magnesium chloride). We produce lithium carbonate and lithium hydroxide at our plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama.

Our products are divided into six categories: specialty plant nutrients; iodine and its derivatives; lithium and its derivatives; potassium chloride and potassium sulfate; industrial chemicals and other commodity fertilizers. Specialty plant nutrients are premium fertilizers that enable farmers to improve yields and the quality of certain crops. Iodine and its derivatives are mainly used in the X-ray contrast media and biocides industries and in the production of polarizing film, which is an important component in LCD screens. Lithium and its derivatives are mainly used in batteries, greases and frits for production of ceramics. Potassium chloride is a commodity fertilizer that is produced and sold by us worldwide. Potassium sulfate is a specialty fertilizer used primarily in crops such as vegetables, fruits and industrial crops. Industrial chemicals have a wide range of applications in certain chemical processes such as the manufacturing of glass, explosives and ceramics, and, more recently, industrial nitrates are being used in concentrated solar power plants as a means for energy storage. In addition, we complement our portfolio of plant nutrients through the buying and selling of other commodity fertilizers for use mainly in Chile.

For the year ended December 31, 2018, we had revenues of US$2,265.8 million, gross profit of US$782.3 million and profit attributable to controlling interests of US$439.8 million. Our worldwide market capitalization as of December 31, 2018 was approximately US$10.1 billion.

Specialty Plant Nutrition: We produce four main types of specialty plant nutrients: potassium nitrate, sodium nitrate, sodium potassium nitrate and specialty blends. We also sell other specialty fertilizers including third party products. All of these specialty plant nutrients are used in either solid or liquid form mainly on high value crops such as vegetables, fruits and flowers. Our nutrients are widely used in crops that employ modern agricultural techniques such as hydroponics, green housing, fertigation (where fertilizer is dissolved in water prior to irrigation) and foliar application. According to the type of use or application, our products are primarily marketed under the following brands: UltrasolR (fertigation), QropR (open field application), SpeedfolR (foliar application) and AllganicR (organic farming). Specialty plant nutrients have certain advantages over commodity fertilizers, such as rapid and effective absorption (without requiring nitrification), superior water solubility, increased soil pH (which reduces soil acidity) and low chloride content. One of the most important products in this business line is potassium nitrate, which is sold in crystalline or prill form, allowing for multiple application methods. Crystalline potassium nitrate products are ideal for application by fertigation and foliar sprays, and potassium nitrate prills are suitable for soil applications.

The new needs of more sophisticated customers demand that the industry provide integrated solutions rather than individual products. Our products, including customized specialty blends that meet specific needs along with the agronomic service provided, allow to create plant nutrition solutions that add value to crops through higher yields and better quality production. Because our products are derived from natural nitrate compounds or natural potassium brines, they have certain advantages over synthetically produced fertilizers, including the presence of certain beneficial trace elements, which makes them more attractive to customers who prefer products of natural origin. As a result, specialty plant nutrients are sold at a premium price compared to commodity fertilizers.

Iodine and its Derivatives: We believe that we are the world’s leading producer of iodine and iodine derivatives, which are used in a wide range of medical, pharmaceutical, agricultural and industrial applications, including x-ray contrast media, polarizing films for LCD/LED, antiseptics, biocides and disinfectants, in the synthesis of pharmaceuticals, electronics, pigments and dye components.

Lithium and its Derivatives: We are a leading producer of lithium carbonate, which is used in a variety of applications, including electrochemical materials for batteries, frits for the ceramic and enamel industries,



heat-resistant glass (ceramic glass), air conditioning chemicals, continuous casting powder for steel extrusion, primary aluminum smelting process, pharmaceuticals and lithium derivatives. We are also a leading supplier of lithium hydroxide, which is primarily used as an input for the lubricating greases industry and for certain cathodes for batteries.

Potassium: We produce potassium chloride and potassium sulfate from brines extracted from the Salar de Atacama. Potassium chloride is a commodity fertilizer used to fertilize a variety of crops including corn, rice, sugar, soybean and wheat. Potassium sulfate is a specialty fertilizer used mainly in crops such as vegetables, fruits and industrial crops.

Industrial Chemicals: We produce three industrial chemicals: sodium nitrate, potassium nitrate and potassium chloride. Sodium nitrate is used primarily in the production of glass, explosives, and metal treatment. Potassium nitrate is used in the manufacturing of specialty glass, and it is also an important raw material for the production of frits for the ceramics and enamel industries. Solar salts, a combination of potassium nitrate and sodium nitrate, are used as a thermal storage medium in concentrated solar power plants. Potassium chloride is a basic chemical used to produce potassium hydroxide, and it is also used as an additive in oil drilling as well as in food processing, among other uses. We market our industrial chemicals using the following brands: QSodiumNitrate™, QPotassiumNitrate™, and QPotassiumChloride™.

Other Products and Services: We also sell other fertilizers and blends, some of which we do not produce. We are the only company that produces and distributes the three main potassium sources: potassium nitrate, potassium sulfate and potassium chloride.

## New Business Ventures

We constantly evaluate opportunities that are consistent with our existing and new businesses. We seek to acquire interests in projects both inside and outside of Chile where we believe we have sustainable competitive advantages, and we hope to continue doing so in the future.

In addition, we are actively conducting exploration for metallic minerals in the mining properties we own. If such minerals are found, we may decide to exploit, sell or enter into an association to extract these resources. Our exploration efforts are currently focused on the layer of bedrock that lies beneath the caliche ore that we use as the primary raw material in the production of iodine and nitrates. This bedrock has significant potential for metallic mineralization, particularly copper and gold. A significant portion of our mining properties are located in the Antofagasta region of Chile, where many large copper producers operate.

We have an in-house geological exploration team that explores the area directly, identifying drilling targets and assessing new prospects. In 2018, the team identified eight new targets and confirmed mineralization in four of the targets, using its own truck-mounted drill rigs. The number of perforated meters reached 32,862 meters, and were made with four machines of which three were internal and the other external. We also have a metal business development team that works to engage partners interested in investing in metal exploration within our mining properties. As of December 31, 2018, we had six option agreements in place with five companies, including small junior mining companies, private equity firms and large mining companies. We have entered into an exploration and purchase option agreement with a private Chilean company for an area of interest. We are participating in the formation of two joint ventures as a result of exercising an option agreement a junior company.

## Main Business Lines

## Specialty Plant Nutrition

In 2018, specialty plant nutrients revenues increased to US$781.8 million, representing 34.5% of our total revenues for that year. We believe that we are the world’s largest producer of potassium nitrate. We estimate that our sales accounted for approximately 56% of global potassium nitrate sales for all applications by volume in 2018, an increase from 53% in 2017. During 2018, the potassium nitrate market increased by approximately 7%. These estimates do not include potassium nitrate produced and sold locally in China, only Chinese net imports and exports.

In addition to potassium nitrate, we produce the following specialty plant nutrients: sodium nitrate, sodium potassium nitrate and specialty blends (containing various combinations of nitrogen, phosphate and potassium and generally known as “NPK blends”).

Our specialty plant nutrients have specific characteristics that increase productivity and enhance quality when used on certain crops and soils. Our specialty plant nutrients have significant advantages for certain applications over commodity fertilizers based on nitrogen and potassium, such as urea and potassium chloride.

Our specialty plant nutrients advantages are:



- fully water soluble, allowing their more efficient use in hydroponics, fertigation, foliar applications and other advanced agricultural techniques thus improving the water use efficiency of crops to help conserve water;

- chloride-free, which prevents chloride toxicity in certain crops associated with high levels of chlorine in plant nutrients;

- provide nitrogen in nitric form, thereby allowing crops to absorb nutrients faster than they absorb urea or ammonium-based fertilizers;

- do not release hydrogen after application, thereby avoiding increased soil acidity;

• possess trace elements, which promote disease resistance in plants; and

• more attractive to customers who prefer products of natural origin.

## Specialty Plant Nutrition: Market

The target market for our specialty plant nutrients includes producers of high-value crops such as vegetables, fruits, industrial crops, flowers, cotton and others. Furthermore, we sell specialty plant nutrients to producers of chloride-sensitive crops. Since 1990, the international market for specialty plant nutrients has grown at a faster rate than the international market for commodity-type fertilizers. This is mostly due to: (i) the application of new agricultural technologies such as fertigation and hydroponics, and the increasing use of greenhouses; (ii) the increase in the cost of land and the scarcity of water, which has forced farmers to improve their yields and reduce water use; and (iii) the increase in demand for higher quality crops, such as fruits and vegetables.

Over the last ten years, the compound annual growth rate for vegetable production per capita was 3% while the compound annual growth rate for the world population was closer to 1%.

Worldwide scarcity of water and arable land drives the development of new agricultural techniques to maximize the use of these resources. Irrigation has grown at an average annual rate of 1% during the last 20 years (a pace similar to population growth). However, microirrigation has grown at 10% per year over the same period. Microirrigation systems, which include drip irrigation and micro-sprinklers, are the most efficient forms of technical irrigation. These applications require fully water-soluble plant nutrients. Our nitrate-based specialty plant nutrients are fully soluble in water and provide nitrogen in nitric form, which helps crops absorb these nutrients faster than they absorb urea- or ammonium-based fertilizers, facilitating a more efficient application of nutrients to the plant and thereby increasing the crop’s yield and improving its quality.

The ratio of microirrigation to total irrigated hectares in Asia is approximately 3%, the lowest ratio of any region in the world. This represents a high potential for microirrigation, which is reflected in the high growth rates in Asia in recent years.

Potassium nitrate in China is an important market, although currently its demand is largely fulfilled by domestic producers. Demand totals approximately 400,000 to 420,000 metric tons, of which approximately 130,000 is related to the tobacco industry and approximately 120,000 is related to the horticulture business. Of the total, between 20,000 and 30,000 metric tons are imports.

## Specialty Plant Nutrition: Our Products

Potassium nitrate, sodium potassium nitrate and specialty blends are higher margin products derived from, or consisting of, sodium nitrate, and they are all produced in crystallized or prilled form. Specialty blends are produced using our own specialty plant nutrients and other components at blending plants operated by us or our affiliates and related companies in Chile, the United States, Mexico, the United Arab Emirates, South Africa, Turkey, China, India, Thailand, Brazil, Spain, the Netherlands and Peru.



The following table shows our sales volumes of and revenues from specialty plant nutrients for 2018, 2017 and 2016:

<table><tr><td></td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Sales volumes (Th. MT)</td><td></td><td></td><td></td></tr><tr><td>Sodium nitrate</td><td>25.0</td><td>26.7</td><td>24.4</td></tr><tr><td>Potassium nitrate and sodium potassium nitrate</td><td>673.4</td><td>601.4</td><td>475.8</td></tr><tr><td>Specialty blends \( ^{(1)} \)</td><td>242.5</td><td>209.0</td><td>213.5</td></tr><tr><td>Other specialty plant nutrients \( ^{(2)} \)</td><td>141.6</td><td>129.1</td><td>127.2</td></tr><tr><td>Revenues (in US) millions</td><td>781.8</td><td>697.3</td><td>623.9</td></tr></table>

(1) Includes Yara’s products sold pursuant to our commercial agreement.

(2) Includes trading of other specialty fertilizers.

In 2018, our specialty plant nutrients revenues increased to US$781.8 million, representing 35% of our total revenues for that year and a 12.1% increase from US$697.3 million in specialty plant nutrients revenues in 2017. Prices increased approximately 0.07% in 2018.

Depending on the systems used to apply specialty nutrients, fertilizers can be classified as specialty field fertilizers or water-soluble fertilizers.

Specialty field fertilizers are applied directly to the soil, manually or in a mechanized fashion. Their high solubility levels, lack of chloride and absence of acidic reactions make them particularly advantageous for tobacco, potatoes, coffee, cotton and a wide range of fruits and vegetables.

Water-soluble fertilizers are specialty nutrients that are delivered to the crops using modern irrigation systems. As these systems feature refined technology, the products used in them must be highly soluble, rich in nutrients, free of impurities and insoluble substances, and with a low salinity index. The leading nutrient in this segment is potassium nitrate, whose optimal balance of nitric nitrogen and chloride-free potassium (the two macronutrients most needed by plants) make it an indispensable source of nutrition for crops that use modern irrigation systems.

Potassium nitrate is widely known to be a vital component in foliar feeding applications, where usage is recommended in order to stave off nutritional deficiencies before the first symptoms appear, correct any deficiencies that arise and prevent physiological stress. This nutrient also helps promote a suitable balance between fruit production and/or growth, and plant development, particularly in crops with physiological disorders.

Foliar feeding with potassium nitrate can have beneficial effects:

- when soil chemistry limits nutrient solubility and availability (pH, organic matter, type and percentage of clay);

- when nutrient absorption through the roots is limited as a result of conditions that hamper root growth (temperature, moisture, oxygen and loss of soil structure);

- when the plant’s local internal demand may surpass real internal nutrient redistribution capacity, leaving the demand unsatisfied;

- when nutrient mobility is limited, when plants flower before the leaf growth phase, imposing limiting factors on xylem nutrient transport; and to achieve rapid recovery from leaf stress caused by climatic conditions, soil conditions and irrigation management.



Another benefit of our potassium nitrate is that, according to a 2014 study by the consulting firm Arthur D. Little Benelux, our production process generates up to 40% less greenhouse gases compared to other major potassium nitrate producers in the world.

SQM has consolidated a product portfolio of over 200 specialty fertilizer blends, including top brands such as Ultrasol \( ^{®} \) , for fertigation; Qrop \( ^{®} \) , for application to the soil; Speedfol \( ^{®} \) , for foliar feeding and Allganic \( ^{®} \)  for organic crops.

QropTMKS was added to our portfolio of specialty field fertilizers in 2015. This product was developed by our research and development team and is an improvement to existing products. It is more physically stable and is not required to be transported as hazardous cargo, which means it can be sold in other markets.

During 2017, we worked on the restructuring of the Qrop products portfolio: chloride-free line for direct application to the soil with a variety of specialized formulas and unique mixtures, which make these products highly accurate and quickly available for the plant.

In 2018, we launched new products to the market, such as the Ultrasol \( ^{®} \)  K line in the United States. Ultrasol \( ^{®} \)  K will address the need for potassium-free chloride and a nitrate safe for handling in the liquid fertilizer market, opening new opportunities for SQM in the cultivation of almonds and strawberries, in which water quality and efficiency are very important.

## Specialty Plant Nutrition: Marketing and Customers

In 2018, we sold our specialty plant nutrients in approximately 100 countries and to more than 760 customers. One customer represented more than 10% of our specialty plant nutrition revenues during 2018, representing approximately 23% of our total specialty plant nutrition revenues, and our ten largest customers accounted in the aggregate for approximately 49% of revenues during that period. No supplier accounted for more than 10% of the costs of sales for this business line.

The table below shows the geographical breakdown of our revenues:

<table><tr><td>Revenues Breakdown</td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>North America</td><td>31%</td><td>33%</td><td>33%</td></tr><tr><td>Europe</td><td>25%</td><td>25%</td><td>18%</td></tr><tr><td>Central and South America</td><td>10%</td><td>10%</td><td>11%</td></tr><tr><td>Asia and Others</td><td>34%</td><td>31%</td><td>37%</td></tr></table>

We sell our specialty plant nutrition products outside Chile mainly through our own worldwide network of representative offices and through our distribution affiliates.

We maintain inventory of our specialty plant nutrients in our commercial offices in the main markets of the Americas, Asia, Europe, the Middle East and Africa in order to facilitate prompt deliveries to customers. In addition, we sell specialty plant nutrients directly to some of our large customers. Sales are made pursuant to spot purchase orders and short-term contracts.

As part of our marketing strategy, we provide technical and agronomical assistance and support to our clients. We have specific knowledge resulting from extensive research and numerous studies conducted by our agronomical teams in close contact with producers throughout the world. The solid agronomical knowledge is key for the development of specific formulas and hydroponic and fertirrigation nutritional plans, which allows us to provide expert advice for producing crops that meet high quality standards for the most efficient markets and in the most environmentally challenging conditions.



By working closely with our customers, we are able to identify their needs for new products and a possible existence of higher-value-added markets. Our specialty plant nutrients are used on a wide variety of crops, particularly value-added crops, where the use of our products enables our customers to increase yields and achieve a premium price for their own products.

Our customers are located in both the northern and southern hemispheres. Consequently, we do not believe there are any seasonal or cyclical factors that can materially affect the sales of our specialty plant nutrients.

## Specialty Plant Nutrition: Joint Ventures and Agreements

Consistent with our business strategy, we regularly evaluate opportunities to expand in our current core businesses, including our specialty plant nutrition business, or within new businesses in which we believe we may have sustainable competitive advantages. We evaluate potential acquisitions, joint ventures and alliances with companies both within and outside of Chile, including in other emerging markets.

In May 2008, we signed a joint venture agreement with Miga o for the production and distribution of specialty plant nutrients in China. Through the joint venture, we constructed a potassium nitrate plant with a production capacity of 40,000 metric tons per year. The plant began operating in January 2011.

In May 2009, our subsidiary Soquimich European Holdings entered into an agreement with Coromandel Fertilizers Ltd. to create a joint venture, Coromandel SQM Private Limited, for the production and distribution of water soluble fertilizers in India. The agreement established a 50/50 joint venture. As part of the agreement, a new 15,000 metric ton facility was constructed in the city of Kakinada to produce water soluble NPK grade fertilizers. This new facility began operating in January 2012.

In December 2009, we signed an agreement with the French Roullier Group to form the joint venture SQM Vitas FZCO. This agreement joins two of the largest companies in the businesses of specialty plant nutrition, specialty animal nutrition and professional hygiene. Peru, Brazil and Dubai are the main focus markets of this joint venture. As part of the agreement, our phosphate plant located in Dubai became part of this joint venture.

Between 2010 and 2012, we continued to expand our production capacity of potassium products in our operations in the Salar de Atacama. In 2011, we completed the construction of a new potassium nitrate facility in Coya Sur, increasing our overall production capacity of potassium nitrate by 300,000 metric tons.

In 2012, SQM Vitas FZCO started the construction of new plants in Brazil (Candeias), Peru and South Africa (Durban) for the production of water soluble fertilizers containing different relative amounts of nitrogen, phosphorus and potassium, and at times, smaller amounts of other chemicals. The Candeias Industrial Complex plant in Brazil began operating in March 2012 and has a production capacity of 25,000 metric tons per year.

In 2013, the operations of SQM Vitas Spain in Spain began with a water soluble NPK fertilizer plant that has a production capacity of 15,000 metric tons per year. In 2016, this operation became fully controlled by SQM.

In 2015, an asset transfer agreement, that was signed in December 2014 between Plantacote B.V. and Plantacote N.V., entered into effect. As a result of this agreement, the business and Plantacote \( ^{\circledR} \)  brand were transferred to the new company Plantacote N.V., but with no changes to the business or the Controlled Release Fertilizer project. SQM continues to hold a 50% ownership stake in the company.

In 2015, SQM Vitas South Africa, was acquired by Roulliers and the production facilities in Durban were transferred to SQM Africa Pty Ltd.



In 2016, we began operating soluble specialty plant nutrient production facilities through our joint ventures in Peru, SQM Vitas Perú S.A.C., and the Netherlands, Plantacote N.V. P.E. Netherlands. In addition, a new logistics terminal was opened in the port of Terneuzen in the Netherlands.

In 2017, three new offices started their operations in Imbituba, Rio Grande and Sao Paulo, Brazil, SQM Vitas Brazil Agroindustria, importação e exporção Itda.

In May 2018, our web began operating a new joint venture, Pavoni & C., Spa, with Pavoni, one of the largest specialty fertilizer companies in Italy. The main objective of this business is to improve the nutritional efficiency of crops, the existing fertigation, the quality of fertilizers and their applications, as well as extend the use of fertigation (from microirrigation).

In 2018, our new office and storage facility in Pamira, managed by SQM Colombia SAS, near the Port of Buenaventura in Colombia became operational. The new office was set up to meet the growing needs of customers in the Colombian market, especially those who grow roses and ornamental plants, coffee, bananas and fruit through a complete portfolio of soluble fertilizers and Qrop mixes.

In 2018, we sold our interest in the Charlee SQM Thailand Co. Ltd. joint venture.

In 2018, the production activities of SQM Vitas FZCO ceased due to changes in the expiry of the lease with the port authorities.

Specialty Plant Nutrition: Fertilizer Sales in Chile

We market specialty plant nutrients in Chile through our subsidiary Soquimich Comercial S.A. (“SQMC”).

SQMC is one of the main players in the Chilean market, offering a wide range of products developed specifically for the crops grown in the country which require specialty plant nutrients.

SQMC sells local products as well as products imported from different countries around the world.

All contracts and agreements between SQMC and its foreign suppliers of fertilizers contain standard and customary commercial terms and conditions. SQMC has been able to obtain adequate supplies of these products with good pricing conditions.

SQMC’s total sales reached US$147 million and US$133 million in 2018 and 2017, respectively. During 2018, no client represented more than 10% of the sales of the Company. According to the customs information related to fertilizers, the market participation of fertilizers imported directly by SQMC during 2018 was approximately 13%.

## Specialty Plant Nutrition: Competition

The principal means of competition in the sale of potassium nitrate are product quality, customer service, location, logistics, agronomic expertise and price.

We believe that we are the world’s largest producer of sodium nitrate and potassium nitrate for agricultural use. Our sodium nitrate products compete indirectly with specialty and commodity-type substitutes, which may be used by some customers instead of sodium nitrate depending on the type of soil and crop to which the product will be applied. Such substitute products include calcium nitrate, ammonium nitrate and calcium ammonium nitrate.



In the potassium nitrate market our largest competitor is Haifa Chemicals Ltd. (“Haifa”), in Israel, which is a subsidiary of Trans Resources International Inc. We estimate that sales of potassium nitrate by Haifa accounted for approximately 13% of total world sales during 2018 (excluding sales by Chinese producers to the domestic Chinese market). Haifa had production issues during 2017 and is currently operating at its 50% capacity (one plant). Our sales accounted for approximately 56% of global potassium nitrate sales by volume for the period.

ACF, another Chilean producer, mainly oriented to iodine production, has produced potassium nitrate from caliche ore and potassium chloride since 2005. Kemapco, a Jordanian producer owned by Arab Potash, produces potassium nitrate in a plant located close to the Port of Aqaba, Jordan. In addition, there are several potassium nitrate producers in China, the largest of which are Yuantong and Miga0. Most of the Chinese production is consumed by the Chinese domestic market.

In Chile, our products mainly compete with imported fertilizer blends that use calcium ammonium nitrate or potassium magnesium sulfate. Our specialty plant nutrients also compete indirectly with lower-priced synthetic commodity-type fertilizers such as ammonia and urea, which are produced by many producers in a highly price-competitive market. Our products compete on the basis of advantages that make them more suitable for certain applications as described above.

## Iodine and its Derivatives

We believe that we are the world’s largest producer of iodine. In 2018, our revenues from iodine and iodine derivatives amounted to US$325.0 million, representing 14.3% of our total revenues in that year. We estimate that our sales accounted for approximately 36% of world iodine sales by volume in 2018.

## Iodine: Market

Iodine and iodine derivatives are used in a wide range of medical, agricultural and industrial applications as well as in human and animal nutrition products. Iodine and iodine derivatives are used as raw materials or catalysts in the formulation of products such as X-ray contrast media, biocides, antiseptics and disinfectants, pharmaceutical intermediates, polarizing films for LCD and LED screens, chemicals, organic compounds and pigments. Iodine is also added in the form of potassium iodate or potassium iodide to edible salt to prevent iodine deficiency disorders.

X-ray contrast media is the leading application of iodine, accounting for approximately 23% of demand. Iodine’s high atomic number and density make it ideally suited for this application, as its presence in the body can help to increase contrast between tissues, organs, and blood vessels with similar X-ray densities. Other applications include pharmaceuticals, which we believe account for 13% of demand; LCD and LED screens, 12%; iodophors and povidone-iodine, 9%; animal nutrition, 8%; fluoride derivatives, 7%; biocides, 6%; nylon, 4%; human nutrition, 3% and other applications, 15%.

During 2018, iodine demand grew at a similar rate as in 2017, reaching 36,300 metric tons. Although more traditional uses grew at the same rate as during the previous year, new applications such as carbon energy plants emission control industries and demand growth related to the LED and LCD market resulted higher demand for iodine and derivatives.

## Iodine: Our Products

We produce iodine in our Nueva Victoria plant, near Iquique, and our Pedro de Valdivia plant, close to María Elena. We have a total effective production capacity of approximately 14,000 metric tons per year of iodine, including the Iris plant, which is located close to the Nueva Victoria plant.



Through ASG, we produce organic and inorganic iodine derivatives. ASG was established in the mid-1990s and has production plants in the United States, Chile and France. ASG is the world’s leading inorganic and organic iodine derivatives producer.

Consistent with our business strategy, we are constantly working on the development of new applications for our iodine-based products, pursuing a continuing expansion of our businesses and maintaining our market leadership.

We manufacture our iodine and iodine derivatives in accordance with international quality standards and have qualified our iodine facilities and production processes under the ISO-9001:2008 program, providing third party certification of the quality

The following table shows our total sales volumes and revenues from iodine and iodine derivatives for 2018, 2017 and 2016:

<table><tr><td></td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Sales volumes (Th. MT)</td><td></td><td></td><td></td></tr><tr><td>Iodine and derivatives</td><td>13.3</td><td>12.7</td><td>10.2</td></tr><tr><td>Revenues (in US$ millions)</td><td>325.0</td><td>252.1</td><td>231.1</td></tr></table>

Our revenues increased to US$325.0 million in 2018 from US$252.1 million in 2017. This increase was primarily attributable to the increase in iodine sales volume and average prices during 2018. Average iodine prices were approximately 23% higher in 2018 than in 2017, reaching US$24/kg. Our sales volumes increased 5% in 2018, outpacing global iodine demand growth.

## Iodine: Marketing and Customers

In 2018, we sold our iodine products in approximately 52 countries to approximately 283 customers, and most of our sales were exports. Four customers each accounted for more than 10% of our iodine revenues in 2017. These four customers accounted for approximately 53% of revenues, and our ten largest customers accounted in the aggregate for approximately 77% of revenues. No supplier accounted for more than 10% of the cost of sales of this business line.

The following table shows the geographical breakdown of our revenues:

<table><tr><td>Sales Breakdown</td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>North America</td><td>26%</td><td>25%</td><td>25%</td></tr><tr><td>Europe</td><td>34%</td><td>31%</td><td>36%</td></tr><tr><td>Central and South America</td><td>2%</td><td>0%</td><td>0%</td></tr><tr><td>Asia and Others</td><td>38%</td><td>43%</td><td>38%</td></tr></table>

We sell iodine through our own worldwide network of representative offices and through our sales, support and distribution affiliates. We maintain inventories of iodine at our facilities throughout the world to facilitate prompt delivery to customers. Iodine sales are made pursuant to spot purchase orders or within the framework of supply agreements. Supply agreements generally specify annual minimum and maximum purchase commitments, and prices are adjusted periodically, according to prevailing market prices.

## Iodine: Competition

The world’s main iodine producers are based in Chile, Japan and the United States. Iodine is also produced in Russia, Turkmenistan, Azerbaijan, Indonesia and China.



Iodine is produced in Chile using a unique mineral known as caliche ore, whereas in Japan, the United States, Russia, Turkmenistan, Azerbaijan, and Indonesia, producers extract iodine from underground brines that are mainly obtained together with the extraction of natural gas and petroleum. In China, iodine is extracted from seaweed.

Five Chilean companies accounted for approximately 59% of total global sales of iodine in 2018, including SQM, with approximately 36%, and four other producers, accounting for the remaining 23%. The other Chilean producers are: Atacama Chemical S.A. (Cosayach), controlled by the Chilean holding Inverraz S.A.; ACF Minera S.A. owned by the Chilean family Urruticoechea; Algorta Norte S.A., a joint venture between ACF Minera S.A. and Toyota Tsusho; and Atacama Minerals, recently acquired by Chinese company Tewoo.

We estimate that eight Japanese iodine producers accounted for approximately 29% of global iodine sales in 2018, including recycled iodine.

We estimate that iodine producers in the United States (one of which is owned by Toyota Tsusho and another is owned by Ise Chemicals Ltd., both of which are Japanese companies) accounted for nearly 5% of world iodine sales in 2018.

Iodine recycling is a growing trend worldwide. Several producers have recycling facilities where they recover iodine and iodine derivatives from iodine waste streams.

We estimate the 17% of the iodine supply come from iodine recycling. Through ASG or alone, we are also actively participating in the iodine recycling business using iodinated side-streams from a variety of chemical processes in Europe and the United States.

The prices of iodine and iodine derivative products are determined by market conditions. World iodine prices vary depending upon, among other things, the relationship between supply and demand at any given time. Iodine supply varies primarily as a result of the production levels of the iodine producers (including us) and their respective business strategies. Our annual average iodine sales prices increased to approximately US$24 per kilogram in 2018, higher than the prices observed in 2017.

Demand for iodine varies depending upon overall levels of economic activity and the level of demand in the medical, pharmaceutical, industrial and other sectors that are the main users of iodine and iodine-derivative products. Certain substitutes for iodine are available for certain applications, such as antiseptics and disinfectants, which could represent a cost-effective alternative to iodine depending on prevailing prices.

The main factors of competition in the sale of iodine and iodine derivative products are reliability, price, quality, customer service and the price and availability of substitutes. We believe we have competitive advantages compared to other producers due to the size and quality of our mining reserves and the available production capacity. We believe our iodine is competitive with that produced by other manufacturers in certain advanced industrial processes. We also believe we benefit competitively from the long-term relationships we have established with our largest customers.

## Lithium and its Derivatives

In 2018, our revenues from lithium sales amounted to US$734.8 million, representing 32.4% of our total revenues. We believe we are one of the world’s largest producers of lithium carbonate and lithium hydroxide, and we estimate that our sales volumes accounted for approximately 17% of the global lithium chemicals sales volumes.

Lithium: Market



The lithium market can be divided into (i) lithium minerals for direct use (in which market SQM does not participate directly), (ii) basic lithium chemicals, which include lithium carbonate and lithium hydroxide (as well as lithium chloride, from which lithium carbonate may be made), and (iii) inorganic and organic lithium derivatives, which include numerous compounds produced from basic lithium chemicals (in which market SQM does not participate directly).

Lithium carbonate and lithium hydroxide are principally used to produce the cathodes for rechargeable batteries, taking advantage of lithium’s extreme electrochemical potential and low density. Batteries are the leading application for lithium, accounting for approximately 65% of total lithium demand, including batteries for electric vehicles, which accounted for approximately 36% of total lithium demand.

There are many other applications both for basic lithium chemicals and lithium derivatives, such as lubricating greases (approximately 7% of total lithium demand), heat-resistant glass (ceramic glass) (approximately 5% of total lithium demand), chips for the ceramics and glaze industry (approximately 3% of total lithium demand), chemicals for air conditioning (approximately 2% of total lithium demand), and many others, including air treatment systems, pharmaceutical synthesis and metal alloys.

Lithium’s main properties, which facilitate its use in this range of applications, are that it:

• is the lightest solid metal and element at room temperature;

• is low density;

• has a low coefficient of thermal expansion;

• has high electrochemical potential; and

• has a high specific heat capacity.

During 2018, lithium chemicals demand increased by approximately 27%, reaching approximately 269,000 metric tons. We expect applications related to energy storage to continue driving demand in the coming years.

## Lithium: Our Products

We produce lithium carbonate at our Salar del Carmen facilities, near Antofagasta, Chile, from highly concentrated lithium chloride produced in the Salar de Atacama, as a by-product of the potassium chloride production. The annual production capacity of our lithium carbonate plant at the Salar del Carmen is 70,000 metric tons per year. In the future, we plan to increase our production capacity to 180,000 metric tons per year. We believe that the technologies we use, together with the high concentrations of lithium and the characteristics of the Salar de Atacama, such as high evaporation rate and concentration of other minerals, allow us to be one of the lowest cost producers worldwide.

We also produce lithium hydroxide at the same plant at the Salar del Carmen, next to the lithium carbonate operation. The lithium hydroxide facility has a production capacity of 13,500 metric tons per year and is one of the largest plants in the world.

The following table shows our total sales volumes and revenues from lithium and its derivatives for 2018, 2017 and 2016:

<table><tr><td></td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Sales volumes (Th. MT)</td><td></td><td></td><td></td></tr><tr><td>Lithium and derivatives</td><td>45.1</td><td>49.7</td><td>49.7</td></tr><tr><td>Revenues (in US$ millions)</td><td>734.8</td><td>644.6</td><td>514.6</td></tr></table>



Our revenues in 2018 reached US$734.8 million, a 14.0% increase from US$644.6 million in 2017, due to significantly higher prices during the year. The average price for 2018 was approximately 25.6% higher than the average price in 2017.

## Lithium: Marketing and Customers

In 2018, we sold our lithium products in approximately 42 countries to approximately 160 customers, and most of our sales were to customers outside of Chile. Two customers each accounted for more than 10% of our lithium revenues in 2018, accounting for approximately 30% of our lithium revenues. Our ten largest customers accounted in the aggregate for approximately 74% of revenues. No supplier accounted for more than 10% of the cost of sales of this business line.

The following table shows the geographical breakdown of our sales for 2018, 2017 and 2016:

<table><tr><td>Sales Breakdown</td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>North America</td><td>9%</td><td>7%</td><td>8%</td></tr><tr><td>Europe</td><td>14%</td><td>14%</td><td>19%</td></tr><tr><td>Central and South America</td><td>1%</td><td>1%</td><td>1%</td></tr><tr><td>Asia and Others</td><td>76%</td><td>79%</td><td>73%</td></tr></table>

We sell lithium carbonate and lithium hydroxide through our own worldwide network of representative offices and through our sales, support and distribution affiliates. We maintain inventories of these products at our facilities throughout the world to facilitate prompt delivery to customers. Sales of lithium carbonate and lithium hydroxide are made pursuant to spot purchase orders or within the framework of supply agreements. Supply agreements generally specify annual minimum and maximum purchase commitments, and prices are adjusted periodically, according to prevailing market prices.

## Lithium: Competition

Lithium is produced mainly from two sources: (i) concentrated brines and (ii) minerals. During 2018, the main lithium brines producers were Chile, Argentina and China, while the main lithium mineral producers were Australia and China. With total sales of approximately 45,100 metric tons of lithium carbonate equivalent (LCE), SQM’s market share of lithium chemicals was approximately 17% in 2018. One of our main competitors is Albemarle Corporation (“Albemarle”), which produces lithium carbonate and lithium chloride in Chile and the United States, along with lithium derivatives in the United States, Germany, Taiwan and China, with a market share of approximately 28%. Albemarle also owns 49% of Talison Lithium Pty Ltd. (“Talison”), an Australian company, that is the largest producer of concentrated lithium minerals in the world, based in Western Australia. The remaining 51% of Talison is owned by Sichuan Tianqi Lithium Industries (“Tianqi”), a Chinese company producing basic lithium chemicals in China from concentrated lithium minerals. Talison sells a part of its concentrated lithium mineral production to the direct use market, but most of its production, representing approximately 26% of total lithium chemical demand, is converted into basic lithium chemicals in China by Tianqi and Albemarle.

Another important competitor is FMC Corporation (“FMC”), with an estimated market share of approximately 7%. FMC has production facilities in Argentina through Minera del Altiplano S.A., where it produces lithium chloride and lithium carbonate. In addition, FMC produces lithium derivatives in the United States and in the United Kingdom. Orocobre Ltd. is also based in Argentina and produces lithium carbonate, reaching a market share of approximately 4%.

Australia is an important source of concentrated lithium minerals. In 2018, two producers doubled their production of concentrated mineral, which is then converted into lithium chemicals in China. One of these producers is a joint venture between Ganfeng Lithium Co. (“Ganfeng”) and Mineral Resources Ltd in the Mt. Marion project. Galaxy Resources Ltd. is another important producer with operations in Mt. Cattlin. Additionally, three new players began shipping concentrated lithium minerals in 2018, Pilbara Minerals



and Altura Mining, both producing from the Pilgangoora deposit, and Alliance Mineral Assets Ltd., producing from the Bald Hill deposit. In addition, there were at least ten other companies producing lithium in China from brines or minerals in 2018.

We believe that lithium production will increase in the near future, balancing the explosive growth in demand. A number of new projects to develop lithium deposits has been announced recently. Some of these projects are already in the advanced stages of development and others could materialize in the medium term.

## Potassium

In 2018, our potassium chloride and potassium sulfate revenues amounted to US$267.5 million, representing 11.8% of our total revenues and a 29.5% decrease compared to 2017, as a result of reduced sales volumes. We estimate that we accounted for less than 2% of global sales of potassium chloride in 2018.

We produce potassium chloride by extracting brines from the Salar de Atacama that are rich in potassium chloride and other salts.

Potassium is one of the three macronutrients that a plant needs to develop. Although potassium does not form part of a plant’s structure, it is essential to the development of its basic functions. Potassium chloride is the most commonly used potassium-based fertilizer. It is used to fertilize crops that can tolerate relatively high levels of chloride, and to fertilize crops that are grown under conditions with sufficient rainfall or irrigation practices that prevent chloride from accumulating to excess levels in the rooting systems of the plant.

Some benefits that may be obtained through the use of potassium are:

• increased yield and quality;

• increased production of proteins;

• increased photosynthesis;

• intensified transport and storage of assimilates;

• prolonged and more intense assimilation period;

• improved water efficiency;

• regulated opening and closure of stomata; and

• synthesis of lycopene.

Potassium chloride is also an important component for our specialty plant nutrition product line, where it is used as a raw material to produce potassium nitrate.

Since 2009, our effective end product capacity has increased to over 2 million metric tons per year, granting us improved flexibility and market coverage.

## Potassium: Market

During the last decade, growth in demand for potassium chloride, and for fertilizers in general, has been driven by several key factors, such as a growing world population, higher demand for protein-based diets and less arable land. All of these factors contribute to fertilizer demand growth as a result of efforts to maximize crop yields and use resources more efficiently. For the last ten years, the compound annual growth for the global potassium chloride market was approximately 1-2%. We estimate that demand totaled approximately 66 million metric tons in 2018, an increase from 64 million metric tons in 2017.

According to studies prepared by the International Fertilizer Industry Association, cereals account for approximately 45% of world potassium consumption, including corn (14%), rice (13%) and wheat (3%).



Oilseeds, predominantly soybeans and palm oil, represent approximately 16% of total potassium demand. Fruits and vegetables account for approximately 22% of world potassium demand, and sugar crops account for close to 7%.

## Potassium: Our Products

Potassium chloride differs from our specialty plant nutrition products because it is a commodity fertilizer and contains chloride. We offer potassium chloride in two grades: standard and compacted. Potassium sulfate is considered a specialty fertilizer and we offer this product in soluble grades.

The following table shows our sales volumes of and revenues from potassium chloride and potassium sulfate for 2018, 2017 and 2016:

<table><tr><td></td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Sales volumes (Th. MT)</td><td></td><td></td><td></td></tr><tr><td>Potassium chloride and potassium sulfate</td><td>831.8</td><td>1,344.3</td><td>1,534.7</td></tr><tr><td>Revenues (in US$ millions)</td><td>267.5</td><td>379.3</td><td>403.3</td></tr></table>

Our revenues in 2018 were US$267.5 million, a 29.5% decrease from US$379.3 million in 2017, due to significantly lower sales volumes during the year. Our sales volumes in 2018 were approximately 38.1% lower than sales volumes reported last year as we focused on maximizing our yields of lithium in the Salar de Atacama.

## Potassium: Marketing and Customers

In 2018, we sold potassium chloride and potassium sulfate to approximately 475 customers in over 58 countries. There were no individual customers that each accounted for more than 10% of our revenues of potassium chloride and potassium sulfate in 2018. We estimate that our ten largest customers accounted in the aggregate for approximately 47% of such revenues. One supplier accounted for more than 10% of the cost of sales of this business line, accounting for approximately 20% of the cost of sales for the business line.

The following table shows the geographical breakdown of our sales for 2018, 2017 and 2016:

<table><tr><td>Sales Breakdown</td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>North America</td><td>19%</td><td>18%</td><td>20%</td></tr><tr><td>Europe</td><td>17%</td><td>19%</td><td>20%</td></tr><tr><td>Central and South America</td><td>30%</td><td>38%</td><td>38%</td></tr><tr><td>Asia and Others</td><td>34%</td><td>25%</td><td>22%</td></tr></table>

## Potassium: Competition

We estimate that we accounted for less than 3% of global sales of potassium chloride in 2018. Our main competitors are Nutrion (formerly PCS), Uralkali, Belaruskali and Mosaic. We estimate that in 2018, PCS accounted for approximately 20% of global sales, Uralkali accounted for approximately 18% of global sales, Belaruskali accounted for approximately 18% of global sales and Mosaic accounted for approximately 15% of global sales.

In the potassium sulfate market, we have several competitors, of which the most important are K+S KALI GmbH (Germany), Tessenderlo Chemie (Belgium) and Great Salt Lake Minerals Corp. (United States). We estimate that these three producers account for approximately 30% of the worldwide production of potassium sulfate. SQM is no longer in the potassium sulfate market with its own production.



## Industrial Chemicals

In 2018, our revenues from industrial chemicals were US$108.3 million, representing approximately 4.8% of our total revenues for that year. We estimate that our market share in the industrial potassium nitrate market was approximately 34% for 2018.

In addition to producing sodium and potassium nitrate for agricultural applications, we produce different grades of these products for industrial applications. The different grades differ mainly in their chemical purity. We enjoy certain operational flexibility producing industrial nitrates, because they are produced from the same process as their equivalent agricultural grades, needing only an additional step of purification. We may, with certain constraints, shift production from one grade to the other depending on market conditions. This flexibility allows us to maximize yields and to reduce commercial risk.

In addition to producing industrial nitrates, we produce, market and sell industrial-grade potassium chloride.

## Industrial Chemicals: Market

Industrial sodium and potassium nitrates are used in a wide range of industrial applications, including the production of glass, ceramics, explosives, charcoal briquettes, metal treatments together with various chemical processes.

In addition, this product line has also experienced growth from the use of industrial nitrates as thermal storage in concentrated solar power plants (commonly known as “CSP”). Solar salts for this specific application contain a blend of 60% sodium nitrate and 40% potassium nitrate by weight ratio used as a storage and heat transfer medium. Unlike traditional photovoltaic plants, these new plants use a “thermal battery” that contains molten sodium nitrate and potassium nitrate, which store the heat collected during the day. The salts are heated up during the day, while the plants are operating under direct sunlight, and at night they release the solar energy that they have captured, allowing the plants to operate even during hours of darkness. Depending on the power plant technology, solar salts are also used as a heat transfer fluid in the plant system and thereby make CSP plants even more efficient, increasing their output and reducing the Levelized Cost of Electricity (LCOE).

Experts believe that CSPs play a critical role in electricity grid stabilization and manageability due to their inherent large scale storage capability. Nevertheless, such large installations are capital intensive and are strongly influenced by the generation mix in each country. Therefore, fluctuations in solar salts demand are unavoidable in terms of quantity and timing. In 2017, we supplied CSP projects in South Africa, Morocco, Kuwait and Israel totaling over 88,000 metric tons. In 2018, we further supplied CSP plants, reaching 47,000 metric tons.

We are also experiencing a growing interest in using solar salts in thermal storage solutions not related to CSP technology. Due to their proven performance, solar salts are being tested in industrial heat processes and heat waste solutions. These new applications may open new opportunities to the solar salts uses in the near future.

Industrial-grade potassium chloride is used as an additive in oil drilling as well as in food processing, among other applications.

## Industrial Chemicals: Our Products

The following table shows our sales volumes of industrial chemicals and total revenues for 2018, 2017 and 2016:



<table><tr><td></td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Sales volumes (Th. MT)</td><td></td><td></td><td></td></tr><tr><td>Industrial chemicals</td><td>135.9</td><td>167.6</td><td>128.9</td></tr><tr><td>Revenues (in US\( millions)</td><td>108.3</td><td>135.6</td><td>104.1</td></tr></table>

Revenues for industrial chemicals decreased from US$135.6 million in 2017 to US$108.3 million in 2018, as a result of lower sales volumes of solar salts in this business line. Sales volumes in 2018 decreased 18.9% compared to sales volumes reported last year.

## Industrial Chemicals: Marketing and Customers

We sold our industrial nitrate products in approximately 54 countries in 2018 to approximately 293 customers. One customer accounted for more than 10% of our revenues of industrial chemicals in 2018, accounting for approximately 28%, and our ten largest customers accounted in the aggregate for approximately 56% of such revenues. No supplier accounted for more than 10% of the cost of sales of this business line.

The following table shows the geographical breakdown of our sales for 2018, 2017 and 2016:

<table><tr><td>Sales Breakdown</td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>North America</td><td>25%</td><td>19%</td><td>24%</td></tr><tr><td>Europe</td><td>16%</td><td>21%</td><td>14%</td></tr><tr><td>Central and South America</td><td>11%</td><td>7%</td><td>9%</td></tr><tr><td>Asia and Others</td><td>48%</td><td>53%</td><td>54%</td></tr></table>

We sell our industrial chemical products mainly through our own worldwide network of representative offices and through our sales and distribution affiliates. We maintain inventories of our different grades of sodium nitrate and potassium nitrate products at our facilities in Europe, North America, South Africa, Asia and South America to achieve prompt deliveries to customers. Our Research and Development department, together with our foreign affiliates, provides technical support to our customers and continuously works with them to develop new products or applications for our products.

## Industrial Chemicals: Competition

We believe we are one of the leading producers of sodium nitrate and potassium nitrate for industrial uses. In the case of industrial sodium nitrate, we estimate that our sales represented close to 41% of world demand in 2018 (excluding internal demand for China and India, for which we believe reliable estimates are not available). Our competitors are mainly based in Europe and Asia, producing sodium nitrate as a by-product of other production processes. In refined grade sodium nitrate, BASF AG (“BASF”), a German corporation and several producers in China and Eastern Europe are highly competitive in the European and Asian markets. Our industrial sodium nitrate products also compete indirectly with substitute chemicals, including sodium carbonate, sodium sulfate, calcium nitrate and ammonium nitrate, which may be used in certain applications instead of sodium nitrate and are available from a large number of producers worldwide.

Our main competitor in the industrial potassium nitrate business is Haifa, which we estimate had a market share of 19%. We estimate that our market share was approximately 34% for 2018.

Producers compete in the market for industrial sodium and potassium nitrate based on reliability, product quality, price and customer service. We believe that we are a low-cost producer of both products and are able to produce high quality products.



In the industrial potassium chloride market, we are a relatively small producer, mainly supplying regional needs.

In the solar salts business, we believe we have been the market leader since we started selling to commercial projects in 2007. Our competitors include Haifa, which is a potassium nitrate supplier, and BASF, which is a sodium nitrate supplier.

## Other Products

A large part of our other revenue is related to fertilizer trading, usually commodities. These fertilizers are traded in large volumes worldwide. We have developed a trade, supply and inventory management business that allows us to respond quickly and effectively to the changing fertilizer market in which we operate and profit on these trades.

## Trend Information

Our revenues increased 5.0% to US2,265.8 million in 2018 from US2,157.3 million in 2017. Gross profit increased 2.6% to US782.3 million in 2018, which represented 34.5% of revenues, from US762.5 million in 2017, which represented 35.3% of revenues. Profit attributable to controlling interests increased 2.8% to US439.8 million in 2018 from US427.7 million in 2017.

We saw lower sales volumes in the lithium business line in 2018 compared to 2017, as a result of the delayed completion and ramp up of our plant expansion to 70,000 metric tons. The lithium market continued its strong growth in 2018, with total demand growth surpassing 27% according to our estimates. Average prices in this business line were 25.6% higher in 2018 when compared to average prices seen during 2017. New supply is entering the market, which could impact our ability to maintain this price premium in 2019. However, there are several lithium grades of different qualities available in the lithium market, and not all products are sold at the same price. We do not believe that all lithium supply entering the market is suitable for all customers. We will focus on providing a high-quality grade lithium to our customers in 2019. We will also rebuild some inventories this year, and as a result of this, we believe our sales volumes in 2019 could be slightly higher than sales volumes seen in 2018. Demand growth in 2018 and continuing into 2019 was led by demand related to batteries for electric vehicles. We believe that full electric vehicle penetration rates reached 2% in 2018, and this number is expected to over double in the next five years. Demand in 2019 is expected to be at least 20% greater than total demand in 2018.

Our sales volumes in the specialty plant nutrition business line increased 12.0% in 2018 compared to 2017, while average prices were flat, increasing by a mere 0.07%. As a result of the higher sales volumes, our revenues in this business line increased by 12.1%. Higher sales volumes seen during 2018 were due to demand growth and limited supply from our competitors. We sell various products within this business line, and most of our specialty fertilizers are sold as either field fertilizers or water soluble fertilizers. Our strategy in this business line has been to focus primarily on the water-soluble fertilizer market, which in general yields higher margins and has more growth potential.

Our sales volumes in the iodine business line increased 5.1% in 2018. We also saw prices increase during 2018; we closed the fourth quarter with average prices of almost US26/kg, exceeding our original expectations. Average prices in 2018 were 22.6% higher than the average prices seen in 2017. Increased sales volumes and higher prices resulted in an increase of 28.9% in our revenues for this business line. According to our estimates, the global iodine demand grew slightly in 2018 reaching almost 36,300 MT and we increased our market share to over 36%.

Our sales volumes in the potassium business line decreased by 38.1% in 2018 compared to 2017. These lower sales volumes were a result of our production limitations as we focused our production efforts in the Salar de Atacama on increasing lithium yields. Furthermore, as a result of environmental compliance



plan that was approved by the Chilean Environmental Authority (SMA) in January 2019, we are temporarily extracting less brine than we had in the past. We had previously announced that potassium chloride and potassium sulfate sales volumes could decrease significantly in 2019 when compared to 2018, we now believe that sales volumes for 2019 will be below 500,000 metric tons. Average prices in the potassium chloride and potassium sulfate business line increased approximately 14.0% during 2018 when compared to 2017, reaching US$322/MT. The higher prices reflected the stronger global demand for potassium chloride in 2018, reaching almost 66 million metric tons.

Our sales volumes in the industrial chemicals product line decreased 18.9% in 2018 compared to 2017, as a result of lower sales volumes of solar salts. Solar salts sales depend on the ramp up of the concentrated solar power plants (CSP) projects and we expect our sales volumes in 2019 to be approximately 50,000 metric tons, very similar to the 47,000 metric tons sold in 2018.

## Production Process

Our integrated production process can be classified according to our natural resources:

• caliche ore deposits, which contain nitrates, iodine and potassium; and

- brines from the Salar de Atacama, which contain potassium, lithium, sulfate, boron and magnesium.

## Caliche Ore Deposits

Caliche ore deposits are located in northern Chile. During 2018, our mining operations concentrated in the first Region where we mainly worked in the mining sector Tente en el Aire and in the mining sector Nueva Victoria Oeste. Mining operations at the Pampa Blanca site, the El Toco mine (which is part of the María Elena site) and the Pedro de Valdivia site were suspended in March 2010, November 2013 and November 2015, respectively, in an effort to optimize our production facilities with lower production costs.

Caliche ore is found under a layer of barren overburden in seams with variable thickness from twenty centimeters to four meters, and with the overburden varying in thickness between half a meter and two meters.

Before proper mining begins, the exploration stage is carried out, including complete geological reconnaissance, sampling and drilling caliche ore to determine the quality and characteristics of each deposit. Drill-hole samples are properly identified and tested at our chemical laboratories. With the exploration information on a closed grid pattern of drill holes, the ore evaluation stage provides information for mine planning purposes. Mine planning is done on a long-term basis (ten years), medium-term basis (three years) and short-term basis (one year). Once all of this information has been compiled, detailed planning for the exploitation of the mine takes place.

The mining process generally begins with bulldozers first breaking and then removing the overburden in the mining area. This process is followed by an inspection and review of the drill holes before production drilling and blasting occurs to break the caliche seams. Front-end loaders load the ore onto off-road trucks, which take it to the leaching heaps to be processed.

During 2018, SQM continued running various tests with a continuous mining equipment replacing the drilling and blasting process and obtaining a smaller ore size (under 6 inches) that allows a better metallurgical recovery. The tests will continue into 2019.

The run of mine ore is loaded in heaps and leached with water to produce concentrated solutions containing iodine, nitrate and potassium. These solutions are then sent to plants where iodine is extracted through both solvent-extraction and blow out processes. The remaining solutions are subsequently sent to solar



evaporation ponds where the solutions are evaporated and salts rich in nitrate and potassium are produced. These concentrated salts are then sent to Coya Sur where they are used to produce potassium nitrate.

During 2018, the Pedro de Valdivia site generated solutions produced by leaching the mine tailings. These solutions are treated at the iodide plant at Pedro de Valdivia. After iodide is obtained, the remaining solutions, which are rich in nitrate and potassium, are sent to the solar evaporation ponds at Coya Sur in order to be used in the production of potassium nitrate.

## Caliche Ore-Derived Products

Caliche ore-derived products are: sodium nitrate, potassium nitrate, sodium potassium nitrate and iodine.

## Sodium Nitrate

During 2018, sodium nitrate for both agricultural and industrial applications was produced by inventory generated at the Pedro de Valdivia facility and subsequently processed at the Coya Sur plants. The production at the Pedro de Valdivia facility, until November 2015, generated approximately 700,000 tons of inventory. As of December 2018, we had approximately 160,000 tons of crystallized sodium nitrate in inventory, which will provide us with enough sodium nitrate to produce finished nitrates for approximately one year. For subsequent production, we are developing the project of adapting the available crystallization plants at Coya Sur to be able to produce sodium nitrate using nitrate salts from our Nueva Victoria facility, which should be completed in 2019.

Crystallized sodium nitrate is an intermediate product that is subsequently processed further at the Coya Sur production plants to produce sodium nitrate, potassium nitrate and sodium potassium nitrate in different chemical and physical forms, including crystallized and prilled products. Finally, the products are transported by truck to our port facilities in Tocopilla for shipping to customers and distributors worldwide.

## Potassium Nitrate

Potassium nitrate is produced at our Coya Sur facility using a production process developed in-house. The brines generated by the leaching process at Pedro de Valdivia are pumped to Coya Sur’s solar evaporation ponds for a nitrate concentration process. After the nitrate concentration process, the brine is pumped to a conversion plant where potassium salts from the Salar de Atacama and nitrate and potassium salts produced at Nueva Victoria or Coya Sur, are added. A chemical reaction begins, transforming sodium nitrate into potassium nitrate and discarding formed sodium chloride. This brine is pumped to a crystallization plant, which crystallizes the potassium nitrate by cooling it at atmospheric pressure, and separating it from the liquid by centrifuge.

Our current potassium nitrate production capacity at Coya Sur is approximately 1,300,000 metric tons per year. Since the end of 2013, we have been working with external advisors to implement the “lean” method of manufacturing in our potassium nitrate plants. We achieved complete implementation of this method of manufacturing during 2015. The improvements we have achieved have enabled us to reduce costs, improve energy consumption, increase the production of potassium nitrate and decrease our accident rates. This method is based on increasing the involvement of our workers in decision-making, and strengthening the leadership of our production supervisors. The goal is to identify opportunities to improve the production process and reduce waste on an ongoing basis.

During 2018, new operational improvements have been achieved by significantly integrating the production process of the Coya Sur facilities, allowing new increases in production capacity without major investments and improving the use of raw materials from the Salar de Atacama and Nueva Victoria.



## Sodium Potassium Nitrate

Sodium potassium nitrate is a mixture of approximately two parts sodium nitrate per one part potassium nitrate. We produce sodium potassium nitrate at our Coya Sur prilling facilities using standard, non-patented production methods we have developed. Crystallized sodium nitrate is supplied together with the crystallized potassium nitrate to the prilling plant where it is mixed producing sodium potassium nitrate, which is then melted and prilled. The prilled sodium potassium nitrate is transported to Tocopilla for bulk shipment to customers.

The production process for sodium potassium nitrate is basically the same as that for sodium nitrate and potassium nitrate. With certain production restraints and following market conditions, we may supply sodium nitrate, potassium nitrate or sodium potassium nitrate, either in prilled or crystallized form.

The sodium nitrate and potassium nitrate produced at Coya Sur are transported to Tocopilla for shipping and delivery to customers and distributors. All potassium nitrate produced in crystallized or prilled form at Coya Sur has been certified by TÜV-Rheiland under the quality standard ISO 9001:2008.

## Iodine and Iodine Derivatives

During 2018, we produced iodine at our facilities at Nueva Victoria (including the Iris facility) and Pedro de Valdivia. Iodine is extracted from solutions produced by leaching caliche ore.

As in the case of nitrates, the process of extracting iodine from the caliche ore is well established, but variations in the iodine and other chemical contents of the treated ore and other operating parameters require a high level of know-how to manage the process effectively and efficiently.

The solutions resulting from the leaching of caliche carry iodine in iodate form. Part of the iodate solution is reduced to iodide using sulfur dioxide, which is produced by combusting (burning) sulfur. The resulting iodide is combined with the rest of the untreated iodate solution to release elemental iodine in low concentrations. The iodine is then extracted from the aqueous solutions and concentrated in iodide form using a solvent extraction and stripping plant in the Pedro de Valdivia and Nueva Victoria facilities and using a blow out plant in Iris. The concentrated iodide is oxidized to metallic iodine, which is then refined through a smelting process and prilled. We have obtained patents in the United States and Chile (Chilean patent number 47,080) for our iodine prilling process.

Prilled iodine is tested for quality control purposes, using international standard procedures that we have implemented. It is then packed in 20 to 50 kilogram drums or 350 to 700 kilogram maxibags and transported by truck to Antofagasta, Mejillones, or Iquique for export. Our iodine and iodine derivatives production facilities have qualified under the ISO-9001:2008 program, providing third-party certification—by TÜV-Rheiland—of the quality management system. The last recertification process was approved in February 2011. Iodine from the Iris plant was certified under ISO-9001:2008 in April 2012.

Our total iodine production in 2018 was 11,255 metric tons: 8,842 metric tons from Nueva Victoria, 1,368 metric tons from Iris, and 1,046 metric tons from Pedro de Valdivia. Nueva Victoria is also equipped to toll iodine from iodide delivered from our other facilities. We have the flexibility to adjust our production according to market conditions. Following the production facility restructuring at Pedro de Valdivia and Nueva Victoria, along with the ramp-up of our new iodide plant in Nueva Victoria, our total current effective production capacity at our iodine production plants is approximately 14,000 metric tons per year.

We use a portion of the iodine we produce to manufacture inorganic iodine derivatives, which are intermediate products used for manufacturing agricultural and nutritional applications, at facilities located near Santiago, Chile. We also produce inorganic and organic iodine derivative products together with Ajay, which purchases iodine from us. In the past, we have primarily sold our iodine derivative products



in South America, Africa and Asia, while Ajay and its affiliates have primarily sold their iodine derivative products in North America and Europe.

In September 2010, CONAMA, currently known as the Environmental Evaluation Service, approved the environmental study of our Pampa Hermosa project in the Tarapacá Region of Chile. This environmental permit allows for an increase in the production capacity of our Nueva Victoria operations to 11,000 metric tons of iodine per year and to produce up to 1.2 million metric tons of crystallized nitrates, mine up to 37 million metric tons of caliche per year and use new water rights of up to 666.2 liters per second. In Iris, we are approved for 2,000 metric tons of iodine production per year, with an annual extraction of caliche ore up to 6.48 million metric tons per year. In recent years, we have made investments in order to increase the water capacity in the Nueva Victoria operations from two water sources approved by the environmental study of Pampa Hermosa, expand the capacity of solar evaporation ponds, and implement new areas of mining and collection of solutions. Our current production capacity at Nueva Victoria is approximately 12,500 metric tons per year of iodine (including the Iris operations) and 900,000 metric tons per year of nitrates. Additional expansions may be implemented from time to time in the future, depending on market conditions.

## Salar de Atacama Brine Deposits

The Salar de Atacama, located approximately 250 kilometers east of Antofagasta, is a salt-encrusted depression in the Atacama Desert, within which lies an underground deposit of brines contained in porous sodium chloride rock fed by an underground inflow from the Andes mountains. Brines are pumped from depths of 1.5 to 60 meters below surface, through a field of wells that are located in the Salar de Atacama, distributed in areas authorized for exploitation, and which contain relatively high concentrations of potassium, lithium, sulfates, boron and other minerals.

The brines are estimated to cover a surface of approximately 2,800 square kilometers and contain commercially exploitable deposits of potassium, lithium, sulfates and boron. Concentrations vary at different locations throughout the Salar de Atacama. Our mining exploitation rights to the Salar de Atacama are pursuant to the Lease Agreement, which expires in 2030. The Lease Agreement, as amended in January 2019 by the Corfo Arbitration Agreement, permits the CCHEN to establish a total accumulated production and sales limit of up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount.

For the year ended December 31, 2018, revenues related to products originating from the Salar de Atacama represented 44% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. All of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. As of December 31, 2018, only 12 years remain on the term of the Lease Agreement.

## Products Derived from the Salar de Atacama Brines

The products derived from the Salar de Atacama brines are: potassium chloride, potassium sulfate, lithium carbonate, lithium hydroxide, lithium chloride, boric acid and biscofite (magnesium chloride).

## Potassium Chloride

We use potassium chloride in the production of potassium nitrate. Production of our own supplies of potassium chloride provides us with substantial raw material cost savings. We also sell potassium chloride to third parties, primarily as a commodity fertilizer.



In order to produce potassium chloride, brines from the Salar de Atacama are pumped to solar evaporation ponds. Evaporation of the water contained in the brine, results in a crystallized mixture of salts with various content levels of potassium, sodium and magnesium. In the first stage of the precipitation, sodium chloride salts are removed; these salts are not used in the production process of other products. After further evaporation, the sodium and potassium salts are harvested and sent for treatment at one of the wet potassium chloride plants where potassium chloride is separated by a grinding, flotation, and filtering process. In the final evaporation stage, salts containing magnesium are harvested and eventually can be treated at one of the cold leach plants where magnesium is removed. Potassium chloride is transported approximately 300 kilometers to our Coya Sur facilities via a dedicated truck transport system, where it is used in the production of potassium nitrate. We sell potassium chloride produced at the Salar de Atacama in excess of our needs to third parties. All of our potassium-related plants in the Salar de Atacama currently have a nominal production capacity in excess of up to 2.6 million metric tons per year. Actual production capacity depends on volume, metallurgical recovery rates and quality of the mining resources pumped from the Salar de Atacama.

The by-products of the potassium chloride production process are (i) solutions remaining after removal of the potassium chloride, which are used to produce lithium carbonate as described below, with the excess amount not required for lithium carbonate production being reinjected into the Salar de Atacama; (ii) sodium chloride, which is similar to the surface material of the Salar de Atacama and is deposited at sites near the production facility and (iii) other salts containing magnesium chloride.

## Lithium Carbonate and Lithium Chloride

After the production of potassium chloride, a portion of the solutions remaining is sent to additional solar concentration ponds adjacent to the potassium concentration ponds. At this stage, the solution is concentrated and purified by precipitation to remove impurities it may still contain, including calcium, sulfate, potassium, sodium and magnesium. Next is the process of concentration and purification of the remaining concentrated solution of lithium chloride, which is transported by truck to the Salar del Carmen production facility located near Antofagasta, approximately 230 kilometers from the Salar de Atacama. At this plant, the solution is further purified and treated with sodium carbonate to produce lithium carbonate, which is dried and then, if necessary, compacted and finally packaged for shipment. The production capacity of our lithium carbonate facility at the end of 2018, following an expansion project was 70,000 metric tons per year. We are now beginning the preparation for the further expansion to 180,000 metric tons per year in the future.

Future production will depend on the actual volumes and quality of the lithium solutions sent by the Salar de Atacama operations, as well as prevailing market conditions. Our future production will also be subject to the extraction limit described in the Lease Agreement mentioned above.

Our lithium carbonate production quality assurance program has been certified by TÜV-Rheiland under ISO 9001 since 2005 and specifically under ISO 9001:2015 since September 2018.

## Lithium Hydroxide

Lithium carbonate is sold to customers, and we also use it as a raw material for our lithium hydroxide production, which started operations at the end of 2005. We currently have two lithium hydroxide plants, one of which entered into operations at the end of 2018, and a total production capacity of 13,500 metric tons per year. These plants are located in the Salar del Carmen, adjacent to our lithium carbonate operations. In the production process, lithium carbonate is reacted with a lime solution to produce lithium hydroxide brine and calcium carbonate salt, which is filtered and piled in reservoirs. The lithium hydroxide solution is evaporated in a multiple effect evaporator and crystallized to produce the lithium hydroxide, which is filtered, dried and packaged for shipment to customers.



Our lithium hydroxide production quality assurance program has been certified by TÜV-Rheiland under ISO 9001 since 2007 and specifically under ISO 9001:2015 since September 2018.

## Potassium Sulfate and Boric Acid

Approximately 12 kilometers northeast of the potassium chloride facilities at the Salar de Atacama, we use the brines from the Salar de Atacama to produce potassium sulfate, potassium chloride (as a by-product of the potassium sulfate process) and, depending on market conditions, boric acid. The plant is located in an area of the Salar de Atacama where high sulfate and potassium concentrations are found in the brines to produce potassium sulfate. The brine is pumped to solar evaporation ponds, where sodium chloride salts are precipitated, harvested and put into piles. After further evaporation, the sulfate and potassium salts precipitate in different concentrations and are harvested and sent for processing to the potassium sulfate plant. Potassium sulfate is produced using flotation, concentration and reaction processes, after which it is crystallized, filtered, dried, classified and packaged for shipment.

Production capacity for the potassium sulfate plant is approximately 340,000 metric tons per year, of which approximately 95,000 metric tons correspond to potassium chloride obtained as a byproduct of the potassium sulfate process. This capacity is part of the total nominal plant capacity of 2.6 million metric tons per year. In our dual plant complex, we may switch, to some extent, between potassium chloride and potassium sulfate production. Part of the pond system in this area is also used to process potassium chloride brines extracted from the low sulfate concentration areas found in the Salar de Atacama. Depending on the conditions for the optimization of the deposit operation and/or market conditions, potassium sulfate production can be modified to produce potassium chloride.

The principal by-products of the production of potassium sulfate are: (i) non-commercial sodium chloride, which is deposited at sites near the production facility and (ii) remaining solutions, which are re-injected into the Salar de Atacama or returned to the evaporation ponds. The principal by-products of the boric acid production process are remaining solutions that are treated with sodium carbonate to neutralize acidity and then are reinjected into the Salar de Atacama.

## Raw Materials

The main raw material that we require in the production of nitrate and iodine is caliche ore, which is obtained from our surface mines. The main raw material in the production of potassium chloride, lithium carbonate and potassium sulfate is the brine extracted from our operations at the Salar de Atacama.

Other important raw materials are sodium carbonate (used for lithium carbonate production and for the neutralization of iodine solutions), sulfuric acid, kerosene, anti-caking and anti-dust agents, ammonium nitrate (used for the preparation of explosives in the mining operations), woven bags for packaging our final products, electricity acquired from electric utilities companies, and liquefied natural gas and fuel oil for heat generation. Our raw material costs (excluding caliche ore and salar brines and including energy) represented approximately 14% of our cost of sales in 2018.

We have been connected to the northern power grid in Chile, which currently supplies electricity to most cities and industrial facilities in northern Chile, since April 2000. We have several electricity supply agreements signed with major producers in Chile, which are within the contract terms. Our electricity needs are primarily covered by the Electrical Energy Supply Agreement that we entered into with AES Gener S.A. on December 31, 2012. Pursuant to the terms of the Electrical Energy Supply Agreement, we are required to purchase an amount of electricity that exceeds the amount that we estimate we will need for our operations. The excess amount is sold at marginal cost, which could result in a material loss for us.



For the supply of liquefied natural gas, in 2013 and 2014 we had a contract with Solgas. For 2015, 2016 2017 and 2018, we executed supply contracts with Enel Chile S.A. as with Solgas, primarily to serve our operations at the Salar del Carmen and Coya Sur.

We obtain ammonium nitrate, sulfuric acid, kerosene and soda ash from several large suppliers, mainly in Chile and the United States, under long-term contracts or general agreements, some of which contain provisions for annual revisions of prices, quantities and deliveries. Diesel fuel is obtained under contracts that provide fuel at international market prices.

We believe that all of our contracts and agreements with third-party suppliers with respect to our main raw materials contain standard and customary commercial terms and conditions.

## Water Supply

We hold water rights for the supply of surface and subterranean water near our production facilities. The main sources of water for our nitrate and iodine facilities at Pedro de Valdivia, María Elena and Coya Sur are the Loa and San Salvador rivers, which run near our production facilities. Water for our Nueva Victoria and Salar de Atacama facilities is obtained from wells near the production facilities. In addition, we buy water from third parties for our production processes at the Salar del Carmen lithium carbonate and lithium hydroxide plants, and we also purchase potable water from local utility companies. We have not experienced significant difficulties obtaining the necessary water to conduct our operations.

## Research and Development, Patents and Licenses, etc.

One of the main objectives of our research and development team is to develop new processes and products in order to maximize the returns obtained from the resources that we exploit. Our research is performed by three different units, whose research topics cover all of the processes involved in the production of our products, including chemical process design, phase chemistry, chemical analysis methodologies and physical properties of finished products.

Our research and development policy emphasizes the following: (i) optimizing current processes in order to decrease costs and improve product quality through the implementation of new technology, (ii) developing higher-margin products from current products through vertical integration or different product specifications, (iii) adding value to inventories and (iv) using renewable energy in our processes.

Our research and development activities have been instrumental in improving our production processes and developing new value-added products. As a result, new methods of extraction, crystallization and finishing products have been developed. Technological advances in recent years have enabled us to improve process efficiency for the nitrate, potassium and lithium operations, improve the physical quality of our prilled products and reduce dust emissions and caking by applying specially designed additives to our products handled in bulk. Our research and development efforts have also resulted in new, value-added markets for our products. One example is the use of sodium nitrate and potassium nitrate as thermal storage in solar power plants.

We have patented several production processes for nitrate, iodine and lithium products. These patents have been filed mainly in the United States, Chile and in other countries when necessary. The patents used in our production processes include Chilean patent No. 47,080 for iodine (production of spherical granules of chemicals that sublime), Japanese patent No. 4,889,848 for nitrates (granular fertilizers) and patent Nos. 41,838 from Chile, 5393-B and 5391-B from Bolivia, AR001918B1 and AR001916B1 from Argentina and 5,676,916 and 5,939,038 from the U.S. for lithium (removal of boron from brines).

## Licenses, Franchises, and Royalties



We do not have contracts that give rise to an obligation for the Company to make payments for licenses, franchises or royalties in any of our business lines, other than payments provided for in the Royalty Law.

We have subscribed purchase option contracts for mining concessions such that, in the event that third parties exercise the respective option, we have the right to receive royalty payments as a result of the exploitation of such concessions.

See section 3) D) Description of Business Environment: Property and Facilities for information about our concessions.

## 3) D) DESCRIPTION OF BUSINESS ENVIRONMENT: PROPERTY AND FACILITIES

We carry out our operations through the use of mining rights, production facilities and transportation and storage facilities. Discussion of our mining rights is organized below according to the geographic location of our mining operations. Our caliche ore mining interests are located throughout the valley of the Tarapacá and Antofagasta regions of northern Chile (in a part of the country known as “el Norte Grande”). From caliche ore, we produce products based on nitrates and iodine, and caliche also contains concentrations of potassium. Our mining interests in the brine deposits of the Salar de Atacama are found within the Atacama Desert, in the eastern region of el Norte Grande. From these brines we produce products based on potassium, sulfate, lithium and boron.

The map below shows the location of our principal mining operations and the exploitation and exploration mining concessions that have been granted to us, as well as the mining properties that we lease from Corfo:







## Mining Concessions

## Mining Concessions for the Exploration and Exploitation of Caliche Ore Mining Resources

We hold our mining rights pursuant to mining concessions for exploration and exploitation of mining resources that have been granted pursuant to applicable law in Chile:

(1) “Mining Exploitation Concessions”: entitle us to use the land in order to exploit the mineral resources contained therein on a perpetual basis, subject to annual payments to the Chilean government.

(2) “Mining Exploration Concessions”: entitle us to use the land in order to explore for and verify the existence of mineral resources for a period of two years, at the expiration of which the concession may be extended one time only for two additional years, if the area covered by the concession is reduced by half. We may alternatively request an exploitation concession in respect of the area covered by the original exploration concession, which must be made within the timeframe established by the original exploration concession.

A Mining Exploration Concession is generally obtained for purposes of evaluating the mineral resources in a defined area. If the holder of the Mining Exploration Concession determines that the area does not contain commercially exploitable mineral resources, the Mining Exploration Concession is usually allowed to lapse. An application also can be made for a Mining Exploitation Concession without first having obtained a Mining Exploration Concession for the area involved.

As of December 31, 2018, the surface area covered by Mining Exploitation Concessions that have been granted in relation to the caliche resources of our mining sites is approximately 573,599 hectares. In addition, as of December 31, 2018, the surface area covered by Mining Exploration Concessions in relation to the caliche resources of our mining sites is approximately 1,700 hectares. We have not requested additional mining rights.

## Mining Concessions for the Exploitation of Brines at the Salar de Atacama

As of December 31, 2018, our subsidiary SQM Salar held exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo’s rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030.

Under the terms of the Project Agreement, Corfo has agreed that it will not permit any other person to explore, exploit or mine any mineral resources in the approximately 140,000 hectares area of the Salar de Atacama mentioned above. The Project Agreement expires on December 31, 2030.

SQM Salar holds an additional 236,842 hectares of constituted Mining Exploitation Concessions in areas near the Salar de Atacama, which correspond to mining reserves that have not been exploited. SQM Salar also holds Mining Exploitation Concessions that are in the process of being granted covering 3,900 hectares in areas near the Salar de Atacama.



In addition, as of December 31, 2018, SQM Salar held Mining Exploration Concessions covering approximately 22,100 hectares and had applied for additional Mining Exploration Concessions of approximately 2,600 hectares. Exploration rights are valid for a period of two years, after which we can (i) request a Mining Exploitation Concession for the land, (ii) request an extension of the Mining Exploration Concession for an additional two years (the extension only applies to a reduced surface area equal to 50% of the initial area) or (iii) allow the concession to expire.

According to the terms of the Lease Agreement, with respect to lithium production, the CCHEN established a total accumulated extraction limit set as amended by the Corfo Arbitration Agreement in January 2018, up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount in the aggregate for all periods while the Lease Agreement is in force. As of December 31, 2018, only 12 years remain on the term of the Lease Agreement.

## Concessions Generally

As of December 31, 2018, approximately 97% of SQM’s mining interests were held pursuant to Mining Exploitation Concessions and 3% pursuant to Mining Exploration Concessions. Of the Mining Exploitation Concessions, approximately 97% already have been granted pursuant to applicable Chilean law, and approximately 3% are in the process of being granted. Of the Mining Exploration Concessions, approximately 87% already have been granted pursuant to applicable Chilean law, and approximately 13% are in the process of being granted.

In 2018, we made payments of approximately US$8.2 million to the Chilean government for Mining Exploration and Exploitation Concessions, including the concessions we lease from Corfo. These payments do not include the payments we made directly to Corfo pursuant to the Lease Agreement, according to the percentages of the sales price of products produced using brines from the Salar de Atacama.

The following table shows the Mining Exploitation and Exploration Concessions held by SQM, including the mining properties we lease from Corfo, as of December 31, 2018:

<table><tr><td></td><td colspan="2">Exploitation Concessions</td><td colspan="2">Exploration Concessions</td><td colspan="2">Total</td></tr><tr><td>Region of Chile</td><td>Total Number</td><td>Hectares</td><td>Total Number</td><td>Hectares</td><td>Total Number</td><td>Hectares</td></tr><tr><td>Region I.</td><td>2,803</td><td>525,946</td><td>47</td><td>16,200</td><td>2,850</td><td>542,146</td></tr><tr><td>Region II.</td><td>8,807</td><td>2,320,527</td><td>125</td><td>53,100</td><td>8,932</td><td>2,373,627</td></tr><tr><td>Region III and others.</td><td>441</td><td>99,885</td><td>40</td><td>11,400</td><td>481</td><td>111,285</td></tr><tr><td>Total.</td><td>12,051</td><td>2,946,358</td><td>212</td><td>80,700</td><td>12,363</td><td>3,027,058</td></tr></table>

The majority of the Mining Exploitation Concessions held by SQM were requested primarily for non-metallic mining purposes. However, a small percentage of our Mining Concessions were requested for metallic mining purposes. The annual payment to the Chilean government for this group of concessions is higher.

Geological studies over mining properties that were requested primarily for non-metallic mining purposes may show that the concession area is of interest for metallic mining purposes, in which case we must inform the Sernageomin, indicating that the type of substance contained by such Mining Concessions has changed, for purposes of the annual payment for these rights.



## Caliche: Facilities and Reserves

## Caliche: Facilities

During 2018, caliche ore mining operations were focused in the first region of Chile, and our Nueva Victoria mine was exploited at two sites: Tente en el Aire and Oeste. In November 2015, the mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced at the Pedro de Valdivia site, in order to take advantage of the highly efficient production facilities at Nueva Victoria. Operations at the Pampa Blanca site were suspended in 2010, and heap leaching operations at the María Elena site were suspended in October 2013, although iodine processing continued until 2017.

## Nueva Victoria

The Nueva Victoria mine and facilities are located 140 kilometers southeast of Iquique and are accessible by highway. Since 2007, the Nueva Victoria mine includes the mining properties Soronal, Mapocho and Iris. At this site, we use caliche to produce salts rich in nitrates and iodine, through heap leaching and the use of solar evaporation ponds. The main production facilities at this site include the operation centers for the heap leaching process, the iodide and iodine plants at Nueva Victoria and Iris and the evaporation ponds at the Sur Viejo sector of the site. The areas currently being mined are located approximately 4 kilometers northeast of Nueva Victoria. Solar energy and electricity are the primary sources of power for this operation.

## Pampa Blanca

The mining facilities at Pampa Blanca, which is located 100 kilometers northeast of Antofagasta, have been suspended since March 2010. At this site, we used caliche to produce nitrates and iodine through heap leaching and the use of solar evaporation ponds. The main production facilities at this site included the operation centers for the heap leaching system and the iodide plant. Electricity was the primary source of power for this operation.

## Pedro de Valdivia

The Pedro de Valdivia mine and facilities are located 170 kilometers northeast of Antofagasta and are accessible by highway. At this site, we used caliche to produce nitrates and iodine through vat leaching and solar evaporation ponds. The main production facilities at this site include the crushing, vat leaching, fines processing, nitrate crystallization plant, and iodide and iodine plants. In November 2015, the mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced. Electricity, natural gas and fuel oil are the primary sources of power for this operation.

## María Elena

The María Elena mine and facilities, named El Toco, are located 220 kilometers northeast of Antofagasta and are accessible by highway. Until February 2010, caliche was used at this facility to produce nitrates and iodine through vat leaching. Subsequently, these facilities were equipped to produce nitrates and iodine through the use of heap leaching and solar evaporation ponds. Heap leaching operations at this site were suspended in October 2013. During 2017, we continued to produce solutions rich in iodine and nitrates by leaching the mine tailings. which were treated at the iodide plant at María Elena, and subsequently the prilled iodine is produced at Pedro de Valdivia. This process was discontinued at the end of 2017.

## Caliche: Reserves

Our in-house staff of geologists and mining engineers prepares our estimates of caliche ore reserves. The Proven and Probable Reserve figures presented below are estimates, and may be subject to modifications due to natural factors that affect the distribution of mineral grades, which would, in turn, modify the recovery of nitrate and iodine. Therefore, no assurance can be given that the indicated levels of recovery of nitrates and iodine will be realized.



We estimate ore reserves based on evaluations, performed by engineers and geologists, of assay values derived from sampling of drill-holes and other openings. Drill-holes have been made at different space intervals in order to recognize mining resources. Normally, we start with 400x400 meters and then we reduce spacing to 200x200 meters, 100x100 meters and 50x50 meters. The geological occurrence of caliche ore is unique and different from other metallic and non-metallic minerals. Caliche ore is found in large horizontal layers at depths ranging from one to four meters and has an overburden between zero and two meters. This horizontal layering is a natural geological condition and allows the Company to estimate the continuity of the caliche bed based on surface geological reconnaissance and analysis of samples and trenches. Mineral resources can be calculated using the information from the drill-hole sampling.

A Mineral Resource is a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form or quantity and of such grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological, metallurgical and technological evidence.

A Measured Resource is the part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. The estimate is based on detailed exploration, sampling and testing information gathered through appropriate sampling techniques from locations such as outcrops, trenches, and exploratory drill holes.

An Indicated Mineral Resource is the part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. The estimate is based on detailed exploration, sampling and testing information gathered through appropriate sampling techniques from locations such as outcrops, trenches and exploratory drill holes.

According to our experience in caliche ore, the grid pattern drill-holes with spacing equal to or less than 100 meters produce data on the caliche resources that is sufficiently defined to consider them Measured Resources and then, adjusting for technical, economic and legal aspects, as Proven Reserves. These reserves are obtained using the Kriging Method and the application of operating parameters to obtain economically profitable reserves.

Similarly, the information obtained from detailed geologic work and samples taken from grid pattern drill-holes with spacing equal to or less than 200 meters can be used to determine Indicated Resources. By adjusting such Indicated Resources to account for technical, economic and legal factors, it is possible to calculate Probable Reserves. Probable Reserves are calculated by using a polygon-based methodology and have an uncertainty or margin of error greater than that of Proven Reserves. However, the degree of certainty of Probable Reserves is high enough to assume continuity between points of observation.

Proven Reserves are the economically mineable part of a Measured Resource. The calculation of the reserves includes the application of mining parameters including maximum overburden, minimum thickness of caliche ore, stripping ratio, cutoff grade and application of dilution factors to the grade values. Appropriate assessments, including pre-feasibility studies or feasibility studies, have been carried out and include consideration of metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

Probable Reserves are the economically mineable part of an Indicated Resource and in some cases a Measured Resource. The calculation of the reserves includes the application of mining parameters including maximum overburden, minimum thickness of caliche ore, stripping ratio, cutoff grade and application of dilution factors to the grade values. Appropriate assessments, including pre-feasibility studies, have been carried out or are in process and include consideration of metallurgical, economic,



marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

The estimates of Proven Reserves of caliche ore at each of our mines as of December 31, 2018 are set forth below. The Company holds 100% of the concession rights for each of these mines.

Notes on reserves:

(1) The Proven Reserves set forth in the table above are shown before losses related to exploitation and mineral treatment. Proven Reserves are affected by mining exploitation methods, which result in differences between the estimated reserves that are available for exploitation in the mining plan and the recoverable material that is finally transferred to the leaching vats or heaps. The average mining exploitation factor for each of our different mines ranges between 80% and 90%, whereas the average global metallurgical recoveries of processes for nitrate and iodine contained in the recovered material vary between 60% and 70%.

(2) The cutoff grades for the Proven and Probable Reserves vary according to the objectives of each mine. These amounts correspond to the averages of the different areas.

(3) Probable Reserves can be expressed as Proven Reserves using a conversion factor, only for purposes of obtaining a projection to be used for long-term planning purposes. On average, this conversion factor is higher than 60%, depending on geological conditions and caliche ore continuity, which vary from mine to mine (Pedro de Valdivia 60%, María Elena 50%, Pampa Blanca 70% and Nueva Victoria 60%).

The complete technical supporting documentation for the information set forth in the table above is contained in the report “Methodology, Procedure, and Classification of SQM’s Nitrate and Iodine Resources and Reserves for the Year 2018,” was prepared for each mine by the geologist Vladimir Tejerina and other engineering professionals employed by SQM and validated by Mr. Sergio Alarcón and Mr. Orlando Rojas.

The proven and probable reserves shown above are the result of the evaluation of approximately 23.38% of the total caliche-related mining property of our Company. However, we have explored more intensely the areas in which we believe there is a higher potential of finding high-grade caliche ore minerals. The remaining 77.62% of this area has not been explored or has had limited reconnaissance, which is not sufficient to determine the potential and hypothetical resources. In 2018, we did not carry out basic reconnaissance of new mining properties. With respect to detailed explorations, in 2018, we carried out recategorizations of indicated resources in Tente en el Aire sectors, totaling 1,658 hectares, which is still in process. Our 2019 exploration program includes the exploration of the Tente en el Air section, which totals 658 hectares, and the basic study of 4,110 hectares of the Hermosa Norte sector. The reserves shown in these tables are calculated based on properties that are not involved in any legal disputes between SQM and other parties.

Caliche ore is the key raw material used in the production of iodine, specialty plant nutrients and industrial chemicals. The following gross margins for the business lines specified were calculated on the same basis as cut off grades used to estimate our reserves. We expect costs to remain relatively stable in the near future.

We maintain an ongoing program of exploration and resource evaluation on the land surrounding our production mines, and other sites for which we have the appropriate concessions.

## Brines from the Salar de Atacama: Facilities and Reserves

## Salar de Atacama: Facilities

## Salar de Atacama

Our facilities at the Salar de Atacama are located 208 kilometers to the east of the city of Antofagasta and 188 kilometers to the southeast of the city of María Elena. At this site we use brines extracted from the salar to produce potassium chloride, potassium sulfate, boric acid, magnesium chloride salts and lithium solutions, which are subsequently sent to our lithium carbonate plant at the Salar del Carmen for processing. The main production plants at this site include the potassium chloride flotation plants (MOP-H I and II), the potassium carnalite plants (PC I and extension), the potassium sulfate flotation plant (SOP-H), the boric acid plant (ABO), the potassium chloride drying plant (Dual Plant or MOP-S), the potassium chloride compacting plant (MOP-G), the potassium sulfate drying plant (SOP-S) and the potassium sulfate compacting plant (SOP-G). Solar energy is the primary energy source used for the Salar de Atacama operations.

## Salar de Atacama: Reserves

Our in-house staff of hydrogeologists and geologists prepares our estimates of the reserve base of potassium, sulfate, lithium and boron dissolved in brines at the Salar de Atacama. We have exploitation concessions covering an area of 81,920 hectares, in which we have carried out geological exploitation, brine sampling and geostatistical analysis. We estimate that our proven and probable reserves as of December 31, 2018, based on law, geological exploitation, brine sampling and geostatistical analysis up to a depth of 300 meters of our total exploitation concessions, are as follows:

<table><tr><td></td><td>Proven Reserves (1)</td><td>Probable Reserves (1)</td><td>Total Reserves</td></tr></table>



<table><tr><td></td><td>(millions of metric tons)</td><td>(millions of metric tons)</td><td>(millions of metric tons)</td></tr><tr><td>Potassium (K+) (2)</td><td>46.1</td><td>42.0</td><td>88.1</td></tr><tr><td>Sulfate (SO4-2) (3)</td><td>39.0</td><td>45.2</td><td>84.2</td></tr><tr><td>Lithium (Li+) (4)</td><td>4.56</td><td>3.99</td><td>8.55</td></tr><tr><td>Boron (B3+) (5)</td><td>1.38</td><td>1.46</td><td>2.84</td></tr></table>

Notes on reserves:

(1) Metric tons of potassium, sulfate, lithium and boron considered in the proven and probable reserves are shown before losses from evaporation processes and metallurgical treatment. The recoveries of each ion depend on both brine composition and the process applied to produce the desired commercial products.

(2) Recoveries for potassium vary from 47% to 77%.

(3) Recoveries for sulfate vary from 27% to 45%.

(4) Recoveries for lithium vary from 28% to 40%.

(5) Recoveries for boron vary from 28% to 32%.

The cutoff grade for lithium extraction is set at 0.05% Li. The cost of the process is competitive in the market despite a small cost increase due to the expansions in the evaporation area (to reach the required Li concentration) and to the use of additives to maintain the quality of the brine that is used to feed the plant.

A cutoff grade of 1.0% K is used in the calculation, considering a low margin scenario using only MOP-S as and using diluted brine with higher levels of contaminants as the raw material and with recovery yields of approximately 47%, which is on the lower end of the range. In this scenario, considering current market conditions and market conditions from recent years, the production cost of MOP production is still competitive.

The proven and probable reserves are based on production experience, drilling, brine sampling and geostatistic reservoir modeling in order to estimate brine volumes and their composition. We calculate the reserve base, which is the volume of brine effectively drainable or exploitable in each evaluation unit, by building a three-dimensional block model. The following variables are used to populate the model:

- Porosity: obtained from measurements of drainable porosity in core rocks, test pumping data, geophysical records and changes in the level of the brine. The volume of brine is estimated on the basis of the interpolation of the drainable porosity data.

- Grades: The brine chemistry is subjected to an exploratory data analysis and a variographic analysis, in order to determine the chemical populations in the Salar. Subsequently, the grades are interpolated using the Kriging method.

Based on the chemical characteristics, and the volume of brine, we determine the number of metric tons for each of the chemical ions being evaluated. Reserve classification is finally achieved by using geostatistical criteria and hydrogeological knowledge of the units that have been explored, as an indicator between proven and probable reserves.

Proven reserves are defined as hydrogeological units with proven historical brine yield production, and a quality and piezometric brine monitoring network to control brine evolution over time.

Probable reserves and inferred resources are being continually explored in order to be able to reclassify them as proven reserves and indicated or measured resources, respectively. This exploration includes systematic packer testing, chemical brine sampling and long-term pilot production pumping tests.

We consider chemical parameters to determine the process to be applied to the brines. These parameters are used to estimate potential restrictions on production yields, and the economic feasibility of producing such commercial products as potassium chloride, potassium sulfate, lithium carbonate and boric acid is determined on the basis of the evaluation.

Complementing the reserves information, SQM has an environmental impact assessment (RCA 226/06) which defines a maximum brine extraction until the end of the Lease Agreement (December 31, 2030). Considering the authorized maximum net brine production rates, we have performed hydrogeological simulations using numeric flow and transport models to estimate changes in the volume and quality of the brine during the life of the project, considering the ponds infrastructure projected and existing on January 1, 2019. According to these simulations, a total of 1.24 million metric tons of lithium and 14.9 million metric tons of potassium will be extracted from the producing wells. On the other hand, the proven and probable base reserve in situ, within the authorized area of environmental extraction (RCA 226/06), corresponds to 4.33 million metric tons of lithium and 30.4 million metric tons of potassium, enough to satisfy the demand of the project until the end of the concession.

Brines from the Salar de Atacama are the key raw material used in the production of potassium chloride and potassium sulfate, and lithium and its derivatives. The following gross margins for the business lines



specified were calculated on the same basis as cut off grades used to estimate our reserves. We expect costs to remain relatively stable in the near future.

## Other Production Facilities

## Coya Sur

The Coya Sur site is located approximately 15 kilometers south of María Elena, and production activities undertaken there are associated with the production of potassium nitrate and finished products. The main production plants at this site include four potassium nitrate plants with a total capacity of 1,300,000 metric tons per year. There are also five production lines for crystallized nitrates, with a total capacity of 1,200,000 metric tons per year, and a prilling plant with a capacity of 360,000 metric tons per year. The potassium nitrate produced at Coya Sur is an intermediate product that is used as a raw material for the production of finished products (crystallized nitrates and prilled nitrates). Therefore, the production capacities listed above are not independent of one another and cannot be added together to obtain an overall total capacity. Natural gas is the main source of energy for our Coya Sur operation.

## Salar del Carmen

The Salar del Carmen site is located approximately 14 kilometers to the east of Antofagasta. The production plants at this facility include the lithium carbonate plant, with a production capacity of 70,000 metric tons per year, and the lithium hydroxide plant, with a production capacity of 13,500 metric tons per year. Electricity and natural gas are the main sources of energy for our Salar del Carmen operation.



The following table provides a summary of our production facilities:

(1) Approximate size considers both the production facilities and the mine for María Elena, Nueva Victoria, Pampa Blanca, Pedro de Valdivia and the Salar de Atacama. Mining areas are those authorized for exploitation by the environmental authority and/or Sernageomin.

(2) Weighted average age and gross book value correspond to production facilities, excluding the mine, for María Elena, Nueva Victoria, Pampa Blanca, Pedro de Valdivia and the Salar de Atacama.

(3) Includes production facilities and solar evaporation ponds.

(4) The potassium nitrate produced at Coya Sur is an intermediate product that is used as a raw material for the production of finished products (crystallized nitrates and prilled nitrates). Therefore, the production capacities listed above are not independent of one another and cannot be added together to obtain an overall total capacity.

(5) Includes production facilities, solar evaporation ponds and leaching heaps.

(6) Operations at the El Toco mine at María Elena were suspended in November 2013.

(7) The nominal production capacity for iodine considers the capacity of our plants. The effective capacity is 14,000 metric tons per year.

(8) Operations at Pampa Blanca were suspended in March 2010.

(9) In November 2015, the mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced at the Pedro de Valdivia site, in order to take advantage of the highly efficient production facilities at Nueva Victoria.

(10) Potassium chloride and potassium sulfate are produced in a dual plant, and the production capacity for each of these products depends on the production mix. Therefore, the production capacities for these two products are not independent of one another and cannot be added together to obtain an overall total capacity.

(11) The Tocopilla port facilities were originally constructed in 1961 and have been refurbished and expanded since that time.

The railway line that runs between our Coya Sur production facilities and our Tocopilla port facilities was damaged in August 2015 as a result of storms in the north of Chile. The train is not currently operating and as a consequence, we have replaced the train with trucks to ship products from Coya Sur. Detailed



engineering studies were performed to assess the damage of the railway. During the third quarter of 2016, the report was completed; it concluded that the cost and time needed to repair the railway at this time is not economical in the short and medium term. As a result of this determination, the Company wrote-off the assets related to the train. We do not believe it will materially impact future sales volumes or transportation costs.

We consider the condition of our principal plant and equipment to be good, with the exception of the railway line.

We directly or indirectly through subsidiaries own, lease or hold concessions over the facilities at which we carry out our operations. Such facilities are free of any material liens, pledges or encumbrances, and we believe they are suitable and adequate for the business we conduct in them.

Metric tons of potassium chloride and potassium sulfate and potassium salts produced ..... 1,505 1,881 2,045

(1) In November 2015, mining and nitrate operations at Pedro de Valdivia were suspended, and iodine production was reduced at the Pedro de Valdivia site, in order to take advantage of the highly efficient production facilities at Nueva Victoria.

(2) Operations at the El Toco and Pampa Blanca mines were suspended in November 2013 and March 2010, respectively. During 2014 and 2015, María Elena obtained production from caliche ore exploited in prior years.

(3) Includes production at Coya Sur from treatment of nitrates solutions from María Elena and Pedro de Valdivia, nitrate salts from pile treatment at Nueva Victoria, and net production from NPT, or technical grade potassium nitrate, plants.

(4) Lithium carbonate is extracted at the Salar de Atacama and processed at our facilities at the Salar del Carmen. Potassium salts include synthetic sylvinite produced in the plant and other harvested potassium salts (natural sylvinite, carnalites and harvests from plant ponds) that are sent to Coya Sur for the production of crystallized nitrates.

## Transportation and Storage Facilities

The transportation of our products is carried out by trucks that are operated by dedicated third parties through long-term contracts. Furthermore, we own port and storage facilities for the transportation and management of finished products and consumable materials.

Our main centers for the production and storage of raw materials are the Nueva Victoria, Coya Sur and Salar de Atacama facilities. Other facilities include chemical plants for the finished products of lithium carbonate and lithium hydroxide at the Salar del Carmen plant. The Port of Tocopilla terminal, which we own, has a surface area of approximately 22 hectares and is the principal facility for the storage and shipment of our bulk products and packaged potassium chloride (MOP) and nitrates.

The nitrate finished products are produced at our Coya Sur facilities and then transported via trucks to the Port of Tocopilla terminal where they are stored and shipped, either packaged (polypropylene bags, polyethylene or polypropylene FIBC big bags) or in bulk. The potassium chloride is produced at our Salar de Atacama facilities and we transport it by truck, either to the Port of Tocopilla terminal or the Coya Sur facility. The product transported to Coya Sur is an intermediate product that is used as a raw material for the production of potassium nitrate. On the other hand, the product transported to the Port of Tocopilla is a final product that will be shipped or transported to the client or affiliate. The raw material of nitrate for the production of potassium nitrate in Coya Sur is currently produced at Nueva Victoria and the remaining raw material is provided from historical stock stored in Coya Sur that was produced at the Pedro de Valdivia facility when it was operating. This raw material is obtained from the processing of caliche that is extracted from our mines.

The lithium chloride solution, which contains a high concentration of boron, produced at our Salar de Atacama facilities, is transported to the lithium carbon plant in the Salar del Carmen area where the finished lithium carbonate is produced. Part of the lithium carbonate is provided to the adjacent lithium hydroxide plant where the finished lithium hydroxide is produced. These two products are packed in packaging of distinct characteristics (polyethylene bags, multi-layer or polypropylene FIBC big bags), stored within the same facilities and secured in roofed storerooms. Thereafter, they are consolidated into containers that are transported by trucks to a transit warehouse or directly to port terminals for their subsequent shipment. The port terminals used are currently suited to receive container ships and are situated in Antofagasta, Mejillones and Iquique.

Iodine obtained from the same caliche used for the production of nitrates, is processed, packaged and stored exclusively in the Pedro de Valdivia and Nueva Victoria facilities. The packaging used for iodine are drums and polypropylene FIBC big bags with an internal polyethylene bag and oxygen barrier, which at the time of transportation are consolidated into containers and sent by truck to port terminals suited for their management, principally located in Antofagasta, Mejillones and Iquique. Thereafter, they are sent to



distinct markets by container ship or by truck to Santiago where iodine derivatives are produced in the Ajay-SQM Chile plants.

The Port of Tocopilla terminal facilities are located approximately 186 kilometers north of Antofagasta, approximately 124 kilometers west of María Elena and Coya Sur and 372 kilometers to the west of Salar de Atacama. Our affiliate, Servicios Integrales de Tránsitos y Transferencias S.A. (SIT), operates facilities for the shipment of products and the delivery of certain raw materials based on renewable concessions granted by Chilean regulatory authorities, provided that the facilities are used in accordance with the authorization granted and we pay an annual concession fee. The Port of Tocopilla terminal facilities include a truck weighing machine that confirms product entry into the port and transfers the product to distinct storage zones, a piezometer within the shipping system to carry out bulk product loaded onto ships and a crane with a 40 ton capacity for the loading of sealed product onto ships.

The storage facilities consist of a system of six silos, with a total storage capacity of 55,000 metric tons, and a mixed storage area of open storehouses with a total storage capacity of approximately 250,000 metric tons. In addition, to fulfill future storage needs, we will continue to make investments in accordance with the investment plan outlined by management. The products are also put into bags at the Port of Tocopilla terminal facilities where the bagging capacity is established by two bag packaging machines, one for sacks and polypropylene FIBC big bags and one for FFS polyethylene. The products that are packaged in Tocopilla may be subsequently shipped at the same port or may also be consolidated into trucks or containers for its subsequent dispatch to clients by land or sea through containers from other ports, principally located in Antofagasta, Mejillones and Iquique.

For the transportation of bulk product, the transportation belt system extends across the coastline to deliver products directly to the hatches of bulk cargo ships. The nominal load capacity of this shipping system is 1,200 tons per hour. The transportation of packaged product is carried out utilizing the same bulk cargo ships using trailers without motors located in the dock and loaded by a crane with a 40 ton capacity from the Port of Tocopilla terminal. Thereafter, they are towed and unloaded using ship cranes to the respective warehouses.

We normally contract bulk cargo ships to transfer the product from the Port of Tocopilla terminal to our hubs around the world or to clients directly, who, in certain instances, use their own contracted vessels for delivery.

Tocopilla processes related to the reception, handling, storage and shipment of bulk/packaged nitrates produced at Coya Sur are certified by the third-party organization TÜV-Rheiland under the quality standard ISO 9001:2008.

## Computer System

In addition to the above-listed facilities, we operate various computer and information systems linking our principal subsidiaries to our operating and administrative facilities throughout Chile, and other parts of the world, via two networks. The computer and information system is used mainly for accounting, monitoring of supplies and inventories, billing, quality control, research activities and production process and maintenance control. The mainframe computing system is located at our offices in Santiago.

In addition, we have Cloud technologies, which allow us to support new business processes related to IoT (Internet of Things) and Advanced Analytics and enables the business to respond quickly and at low cost to changing conditions of the business and of the market.

An Advanced Analytical pilot was carried out in one of our production plants, which allowed us to collect information to allow us to advance the predictive short-term and medium-term analysis and possible automation in the long term.



A cyber security review is being carried out to highlight possible risks and mitigate them. Process automation and digitalization projects were initiated at various sites, such as the Port of Tocopilla, with the objective of reducing operational risks, and improving security and operational efficiency, which also includes a modernization of current IT infrastructure and existing communications.

## 3) E) DESCRIPTION OF BUSINESS ENVIRONMENT: RISK FACTORS

## Risk Factors

Our operations are subject to certain risk factors that may affect SQM’s business financial condition or results of operations. In addition to other information contained in this Annual Report, you should carefully consider the risks described below. These risks are not the only ones we face. Additional risks not currently known to us or that are known but that we currently believe are not significant may also affect our business operations. Our business, financial condition, cash flows or results of operations could be materially affected by the occurrence any of these risks.

## Risks Relating to our Business

We could be subject to numerous risks in the U.S. and Chile as a result of ongoing investigations by the Chilean Internal Revenue Service and the Chilean Public Prosecutor in relation to certain payments made by SQM between the tax years 2009 and 2015

In 2015, the Chilean Internal Revenue Service (Servicio de Impuestos Internos or “SII”) and the Chilean Public Prosecutor brought a number of criminal and administrative proceedings following investigations related to the payment of invoices by SQM and its subsidiaries SQM Salar S.A. (“SQM Salar”) and SQM Industrial S.A., for services that may not have been properly supported or that may not have been necessary to generate corporate income, against (i) Patricio Contesse G., the Company’s former CEO whose employment was terminated in May 2015, (ii) Mr. Contesse and the Company’s then-current CEO, Patricio de Solminihac, and CFO (now CEO), Ricardo Ramos, in their capacities as the Company’s tax representatives and (iii) five then-current and former members of the Company’s Board of Directors. All the claims against Messrs. de Solminihac and Ramos were subsequently dismissed. The lawsuits against Mr. Contesse continue and the five Board members are appealing the fines of approximately US$36,000 imposed on each of them.

On October 14, 2015, two class action complaints then pending against the Company, our former CEO and then-current CEO and CFO, alleging violations of the U.S. securities laws in connection with the subject matter of the investigations described above, were consolidated into a single action in the United States District Court for the Southern District of New York. On November 13, 2015, our former CEO and then-current CEO and CFO were voluntarily dismissed from the case without prejudice. On January 15, 2016, the lead plaintiff filed a consolidated class action complaint exclusively against the Company. On January 10, 2018, the lead plaintiff filed a motion to certify a class consisting of all persons who purchased SQM American Depositary Shares (“ADS”) between June 30, 2010 and March 18, 2015, and such motion remains pending before the court.

During 2015, the ad-hoc committee of the Board of Directors (the “ad-hoc Committee”) established in February 2015 to conduct an internal investigation into the matters that were the subject of the SII and Chilean Public Prosecutor investigation also conducted an investigation into whether the Company faced possible liability under the Foreign Corrupt Practices Act (“FCPA”). The ad-hoc Committee engaged its own separate counsel, Shearman & Sterling LLP, which presented a report to the Board of Directors on December 15, 2015.



Following the presentation by the ad-hoc Committee of its findings to the Board of Directors, the Company voluntarily shared the findings of the ad-hoc Committee investigation with authorities in Chile and the U.S. (including the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”)).

On January 13, 2017, the Company and the DOJ reached agreement on the terms of a Deferred Prosecution Agreement (“DPA”) that would resolve the DOJ’s inquiry, based on alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act. Among other terms, the DPA called for the Company to pay a monetary penalty of US$15,487,500, and engage a compliance monitor for a term of two (2) years. Upon successful completion of the three (3) year term of the DPA, all charges against the Company will be dismissed. On the same date, the SEC agreed to resolve its inquiry through an administrative cease and desist order, arising out of the alleged violations of the same accounting provisions of the FCPA. Among other terms, the SEC order called for the Company to pay an additional monetary penalty of US$15 million.

On January 26, 2018, the Eighth Lower Criminal Court of Santiago approved a deferred prosecution agreement proposed by the Chilean Public Prosecutor relating to SQM and its subsidiaries, SQM Salar and SQM Nitratos S.A., to suspend an investigation against these entities related to potential corruption issues and responsibility for the lack of supervision and management. Under the deferred prosecution agreement, SQM, SQM Salar and SQM Nitratos S.A., have not admitted responsibility in the matter subject to the investigation but agreed to pay an aggregate amount of (i) Ch$900,000,000 to the Chilean government, and (ii) Ch$1,650,000,000 to various charitable organizations. As of January 26, 2018, these amounts were equivalent to approximately US$1.5 million and US$2.8 million, respectively. In addition, the companies have agreed to provide the Chilean Public Prosecutor with a report on the enhancements to their compliance program, implemented in recent years, with special emphasis on the incorporation of best practices in various jurisdictions. On August 17, 2018, the Eighth Lower Criminal Court of Santiago considered the conditions and decided to terminate the legal process.

In the event that the applicable regulatory authorities believe that the terms of the DPA or the deferred prosecution agreement with the Chilean Public Prosecutor are not complied with, it is possible that such regulatory authorities may reinstate the suspended proceedings against us and may bring further action against us, including in the form of additional inquiries or legal proceedings. Responding to our regulators' inquiries and any future civil, criminal or regulatory inquiries or proceedings diverts our management's attention from day-to-day operations. Additionally, expenses that may arise from responding to such inquiries or proceedings, our review of responsive materials, any related litigation or other associated activities may continue to be significant. Current and former employees, officers and directors may seek indemnification, advancement or reimbursement of expenses from us, including attorneys' fees, with respect to the current inquiry or future proceedings related to this matter. The occurrence of any of the foregoing or adverse determination in litigation or other proceedings or similar actions could materially and adversely affect our business, financial condition, cash flows, results of operations and the prices of our securities.

Legal challenges to the amendments of the Lease Agreement and the Project Agreement relating to the Salar de Atacama concession, if successful, or failure to comply with the requirements of either agreement, could have a material adverse effect on our business, financial condition and results of operations

Our subsidiary SQM Salar S.A. (“SQM Salar”), as leaseholder, holds exclusive and temporary rights over the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to (i) a 1993 lease agreement over mining exploitation concessions between SQM Salar and Corfo, a Chilean government entity (the “Lease Agreement”), and (ii) the Salar de Atacama project agreement between Corfo and SQM Salar (the “Project



Agreement”). Corfo may not unilaterally amend the Lease Agreement or the Project Agreement. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo, maintaining Corfo’s rights over the mining exploitation concessions, and making annual payments to the Chilean government for such concession rights. The Lease Agreement expires on December 31, 2030. Furthermore, under the regulations of the Chilean Nuclear Energy Commission (Comisión Chilena de Energía Nuclear or “CCHEN”), we were originally limited to 180,100 tons of total lithium metallic equivalent (958,672 tons of lithium carbonate equivalent) extraction in the aggregate for all periods. On January 17, 2018, Corfo and our subsidiaries SQM Potasio S.A. and SQM Salar reached an agreement (the “Corfo Arbitration Agreement”) to (i) terminate the previously disclosed arbitration proceedings between Corfo and SQM Salar, which, among other things, sought early termination of the Lease Agreement and (ii) amend the Lease Agreement and the Project Agreement. As part of the agreement to amend the Lease Agreement, Corfo authorized an increase of the production and sales of lithium products produced in the Salar de Atacama up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount. The amendments of the Lease Agreement and the Project Agreement required under Chilean law the issuance of the applicable resolutions of the Office of the Controller General of the Republic (Contraloría General de la República) and the CCHEN, which were issued.

Our business is substantially dependent on the exploitation rights under the Lease Agreement and the Project Agreement, since all of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. For the year ended December 31, 2018, revenues related to products originating from the Salar de Atacama represented 44% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. As of December 31, 2018, only 12 years remain on the term of the Lease Agreement and we had extracted approximately 23% of the total permitted accumulated extraction and sales limit of lithium under the increased lithium extraction and sales limits.

These agreements expire in 2030 and establish a series of obligations with which SQM Salar must comply. A serious failure to comply with these obligations may jeopardize the exploitation rights under the agreements and the continuity of our operations in the Salar de Atacama. While we believe that we have taken the appropriate precautions to ensure compliance with the obligations and conditions in the agreements, there can be no assurance that we will be able to maintain such compliance, which could jeopardize the continued benefits to us of the agreements and could have a material adverse effect on our business, financial condition and results of operations.

On February 15, 2018 and February 16, 2018, the Atacamenos Indigenous Organization (Consejo de Pueblos Atacamenos) initiated legal actions challenging the amendments of the Lease Agreement and the Project Agreement. The legal actions are pending before the Supreme Court of Chile.

In the event the amendments to the Lease Agreement and the Project Agreement under the Corfo Arbitration Agreement are successfully challenged, or the CCHEN authorization for the increased extraction is revoked, there can be no assurance that we will not reach the lithium extraction limit referred to above prior to the expiration of the term of the Lease Agreement. In such event, we would then be unable to continue extraction of lithium under the Lease Agreement, which could have a material adverse effect on our business, financial condition and results of operations.

Our market reputation, commercial dealings or the price of our securities could be adversely affected by the negative outcome of certain proceedings against certain former members of our Board and certain other named defendants

On September 10, 2013, the CMF issued a press release disclosing it had instituted certain administrative proceedings (the “Cascading Companies Proceedings”) against (i) Julio Ponce Lerou (who was the



Chairman of the Board and a director of the Company until April 24, 2015), (ii) Patricio Contesse Fica, who was a director of the Company until April 24, 2015 and was later elected as director on April 27, 2018, and is the son of Patricio Contesse González (who was the Company’s CEO until March 16, 2015), and (iii) other named defendants. The Company has been informed that Mr. Ponce and persons related to him beneficially owned 32% of SQM’s total shares as of December 31, 2018. See “Section 4) A) i) Situation of Control”. The CMF alleged breaches of Chilean corporate and securities laws in connection with acts performed by entities with direct or indirect share ownership interests in SQM (the “Cascading Companies”). The allegations made in connection with the Cascading Companies Proceedings do not relate to the Company’s operations, nor do they relate to any acts or omissions of the Company or any of its directors, officers or employees in their capacities as such.

In connection with the Cascading Companies Proceedings, the CMF alleged the existence of a scheme involving the named defendants whereby, through a number of transactions occurring between 2008 and 2011, the Cascading Companies allegedly sold securities of various companies, at below-market prices to companies related to Mr. Ponce and other named defendants. These companies allegedly subsequently sold such securities after a lapse of time, in most cases back to the Cascading Companies, at prices higher than the purchase price. The CMF alleged violations by the defendants of a number of Chilean corporate and securities laws in furtherance of the alleged scheme.

On January 31, 2014, the CMF added a number of Chilean financial institutions and asset managers, and certain of their controlling persons, executives or other principals, as named defendants to the Cascading Companies Proceedings. On September 2, 2014, the CMF issued a decision imposing an aggregate fine against all of the defendants of UF 4.0 million (approximately US$174 million as of December 31, 2018), including a fine against Mr. Ponce of UF 1.7 million (approximately US$74 million as of December 31, 2018) and a fine against Mr. Contesse Fica of UF 60,000 (approximately US$2.6 million as of December 31, 2018). The defendants are currently challenging the CMF administrative decision before Chilean courts.

The High Complexity Crimes Unit (Unidad de Delitos de Alta Complejidad) of the Metropolitan District Central Northern Attorney’s Office (Fiscalía Metropolitana Centro Norte) is also investigating various criminal complaints filed against various parties to the Cascading Companies Proceedings. The SII requested payment of taxes by the Cascading Companies, and the Cascading Companies filed a complaint with the tax courts.

If, for any reason, the Company is unable to differentiate itself from the named defendants, such failure could have a material adverse effect on the Company’s market reputation and commercial dealings. Furthermore, we cannot assure you that a non-appealable ruling in connection with the Cascading Companies Proceedings or the investigations of the High Complexity Crimes Unit or the SII that is adverse to Mr. Ponce or Mr. Contesse Fica will not have a material adverse effect on our market reputation, commercial dealings and the price of our securities.

Our annual report for the year ended December 31, 2014 on Form 20-F filed with the SEC identified a material weakness in our internal controls over payments directed by the office of the former Chief Executive Officer as of December 31, 2014

In the past, our management determined that the Company did not maintain effective control over payments directed by the office of the former CEO. This determination was reported in our annual report for the year ended December 31, 2014 on Form 20-F, filed with the SEC on May 18, 2015.

We believe we have taken the necessary steps to remediate the identified material weakness and enhance our internal controls. However, any failure to maintain effective internal control over financial reporting could (i) result in a material misstatement in our financial reporting or financial statements that would not be prevented or detected, (ii) cause us to fail to meet our reporting obligations under applicable securities



laws or (iii) cause investors to lose confidence in our financial reporting or financial statements, the occurrence of any of which could materially and adversely affect our business, financial condition, cash flows, results of operations and the prices of our securities.

Volatility of world lithium, fertilizer and other chemical prices and changes in production capacities could affect our business, financial condition and results of operations

The prices of our products are determined principally by world prices, which, in some cases, have been subject to substantial volatility in recent years. World lithium, fertilizer and other chemical prices constantly vary depending upon the relationship between supply and demand at any given time. Supply and demand dynamics for our products are tied to a certain extent to global economic cycles, and have been impacted by circumstances related to such cycles. Furthermore, the supply of lithium, certain fertilizers or other chemical products, including certain products that we provide, varies principally depending on the production of the major producers, (including us) and their respective business strategies.

World prices of potassium-based fertilizers (including some of our specialty plant nutrients and potassium chloride) fluctuated as a result of the broader global economic and financial conditions. During the second half of 2013, potassium prices declined as a result of an unexpected announcement made by the Russian company Uralkali (“Uralkali”) that it was terminating its participation in Belarus Potash Corporation (“BPC”). As a result of the termination of Uralkali’s participation in BPC, there was increased price competition in the market. In 2018, the average price for our potassium chloride and potassium sulfate business line was approximately 14% higher than in 2017. Our sales volumes for this business line were approximately 38% lower in 2018 compared to 2017. We cannot assure you that potassium-based fertilizer prices and sales volumes will not decline in the future.

Iodine prices followed an upward trend beginning at the end of 2008 and continuing through 2012, reaching an average price of approximately US$53 per kilogram in 2012, over 40% higher than average prices in 2011. During the following years, supply growth outpaced demand growth, causing a decline in iodine prices. We obtained an average price for iodine of approximately US$24 per kilogram in 2018, approximately 23% more than average prices obtained in 2017. We cannot assure you that iodine prices or sales volumes will not continue to decline in the future.

In 2018, lithium demand continued to grow, creating tight market conditions and increasing prices by 26% compared to 2017, driven mostly by an increase in demand related to battery use. During the second half of 2018, lithium supply increased, and prices slightly decreased in the fourth quarter. We cannot assure you that lithium prices and sales volumes will not decline in the future.

We expect that prices for the products we manufacture will continue to be influenced, among other things, by worldwide supply and demand and the business strategies of major producers. Some of the major producers (including us) have increased or have the ability to increase production. As a result, the prices of our products may be subject to substantial volatility. High volatility or a substantial decline in the prices or sales volumes of one or more of our products could have a material adverse effect on our business, financial condition and results of operations.

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

We sell our products in more than 110 countries around the world. In 2018, approximately 34% of our sales were made in emerging market countries: 8% in Latin America (excluding Chile); 8% in Africa and the Middle East (excluding Israel); 8% in Chile and 11% in Asia and Oceania (excluding Australia, Japan, New Zealand, South Korea and Singapore). We expect to expand our sales in these and other emerging markets in the future. In addition, we may carry out acquisitions or joint ventures in jurisdictions in which



we currently do not operate, relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. The results of our operations and our prospects in other countries in which we establish operations will depend, in part, on the general level of political stability and economic activity and policies in those countries. Future developments in the political systems or economies of these countries or the implementation of future governmental policies in those countries, including the imposition of withholding and other taxes, restrictions on the payment of dividends or repatriation of capital, the imposition of import duties or other restrictions, the imposition of new environmental regulations or price controls or changes in relevant laws or regulations, could have a material adverse effect on our business, financial condition and results of operations in those countries.

## Our inventory levels may increase for economic or operational reasons

In general, economic conditions or operational factors can affect our inventory levels. Higher inventories carry a financial risk due to increased need for cash to fund working capital and could imply increased risk of loss of product. At the same time, lower levels of inventory can hinder the distribution network and process, thus impacting sales volumes. There can be no assurance that inventory levels will remain stable. These factors could have a material adverse effect on our business, financial condition and results of operations.

Our measures to minimize our exposure to bad debt may not be effective and a significant increase in our accounts receivable coupled with the financial condition of customers may result in losses that could have a material adverse effect on our business, financial condition and results of operations

Potentially negative effects of global economic conditions on the financial condition of our customers may include the extension of the payment terms of our accounts receivable and may increase our exposure to bad debt. While we have implemented certain safeguards, such as using credit insurance, letters of credit and prepayment for a portion of sales, to minimize the risk, we cannot assure you that such safeguards will be effective and a significant increase in our accounts receivable coupled with the financial condition of customers may result in losses that could have a material adverse effect on our business, financial condition and results of operations.

New production of iodine or lithium from current or new competitors in the markets in which we operate could adversely affect prices

In recent years, new and existing competitors have increased the supply of iodine and lithium, which has affected prices for both products. Further production increases could negatively impact prices. There is limited information on the status of new iodine or lithium production capacity expansion projects being developed by current and potential competitors and, as such, we cannot make accurate projections regarding the capacities of possible new entrants into the market and the dates on which they could become operational. If these potential projects are completed in the short term, they could adversely affect market prices and our market share, which, in turn, could have a material adverse effect on our business, financial condition and results of operations.

## We have a capital expenditure program that is subject to significant risks and uncertainties

Our business is capital intensive. Specifically, the exploration and exploitation of reserves, mining and processing costs, the maintenance of machinery and equipment and compliance with applicable laws and regulations require substantial capital expenditures. We must continue to invest capital to maintain or to increase our exploitation levels and the amount of finished products we produce.

In addition, we require environmental permits for our new projects. Obtaining permits in certain cases may cause significant delays in the execution and implementation of new projects and, consequently, may require us to reassess the related risks and economic incentives. We cannot assure you that we will be



able to maintain our production levels or generate sufficient cash flow, or that we will have access to sufficient investments, loans or other financing alternatives, to continue our activities at or above present levels, or that we will be able to implement our projects or receive the necessary permits required for them in time. Any or all of these factors may have a material adverse effect on our business, financial condition and results of operations.

High raw materials and energy prices could increase our production costs and cost of sales, and energy may become unavailable at any price

We rely on certain raw materials and various energy sources (diesel, electricity, liquefied natural gas, fuel oil and others) to manufacture our products. Purchases of energy and raw materials we do not produce constitute an important part of our cost of sales, approximately 14% in 2018. In addition, we may not be able to obtain energy at any price if supplies are curtailed or otherwise become unavailable. To the extent we are unable to pass on increases in the prices of energy and raw materials to our customers or we are unable to obtain energy, our business, financial condition and results of operations could be materially adversely affected.

Our reserves estimates are internally prepared and not subject to review by external geologists or an external auditing firm and could be subject to significant changes, which may have a material adverse effect on our business, financial condition and results of operations

Our caliche ore mining reserves estimates and our Salar de Atacama brine mining reserve estimates are prepared by our own geologists and hydrogeologists and are not subject to review by external geologists or an external auditing firm. Estimation methods involve numerous uncertainties as to the quantity and quality of the reserves, and reserve estimates could change upwards or downwards. A downward change in the quantity and/or quality of our reserves could affect future volumes and costs of production and therefore have a material adverse effect on our business, financial condition and results of operations.

## Quality standards in markets in which we sell our products could become stricter over time

In the markets in which we do business, customers may impose quality standards on our products and/or governments may enact stricter regulations for the distribution and/or use of our products. As a result, if we cannot meet such new standards or regulations, we may not be able to sell our products. In addition, our cost of production may increase in order to meet any such newly imposed or enacted standards or regulations. Failure to sell our products in one or more markets or to important customers could materially adversely affect our business, financial condition and results of operations.

## Chemical and physical properties of our products could adversely affect their commercialization

Since our products are derived from natural resources, they contain inorganic impurities that may not meet certain customer or government standards. As a result, we may not be able to sell our products if we cannot meet such requirements. In addition, our cost of production may increase in order to meet such standards. Failure to meet such standards could materially adversely affect our business, financial condition and results of operations if we are unable to sell our products in one or more markets or to important customers in such markets.

Our business is subject to many operating and other risks for which we may not be fully covered under our insurance policies

Our facilities and business operations in Chile and abroad are insured against losses, damage or other risks by insurance policies that are standard for the industry and that would reasonably be expected to be sufficient by prudent and experienced persons engaged in businesses similar to ours.



We may be subject to certain events that may not be covered under our insurance policies, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, as a result of major earthquakes and unexpected rains and flooding in Chile, as well as other natural disasters worldwide, conditions in the insurance market have changed and may continue to change in the future, and as a result, we may face higher premiums and reduced coverage, which could have a material adverse effect on our business, financial condition and results of operations.

## Changes in technology or other developments could result in preferences for substitute products

Our products, particularly iodine, lithium, and their derivatives, are preferred raw materials for certain industrial applications, such as rechargeable batteries and LCDs. Changes in technology, the development of substitute raw materials or other developments could adversely affect demand for these and other products which we produce. In addition, other alternatives to our products may become more economically attractive as global commodity prices shift. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

## We are exposed to labor strikes and labor liabilities that could impact our production levels and costs

Over 93% of our employees are employed in Chile, of which approximately 65% were represented by 22 labor unions as of December 31, 2018. As in past years, we renegotiated collective bargaining agreements with 14 unions, achieving the anticipated renegotiation of 17 collective bargaining agreements by December 31, 2018, one year before the expiration of the agreements. The 17 collective bargaining agreements were renegotiated for the next three years as of that date. We are exposed to labor strikes and illegal work stoppages that could impact our production levels. If a strike or illegal work stoppage occurs and continues for a sustained period of time, we could be faced with increased costs and even disruption in our product flow that could have a material adverse effect on our business, financial condition and results of operations.

Chilean Law No. 20,123, known as the Subcontracting Law, provides that when a serious workplace accident occurs, the company in charge of the workplace must halt work at the site where the accident took place until authorities from either the National Geology and Mining Service (Servicio Nacional de Geología y Minería or “Sernageomin”), the Labor Board (Dirección del Trabajo or “Labor Board”), or the National Health Service (Servicio Nacional de Salud), inspect the site and prescribe the measures such company must take to minimize the risk of similar accidents taking place in the future. Work may not be resumed until the applicable company has taken the prescribed measures, and the period of time before work may be resumed may last for a number of hours, days, or longer. The effects of this law could have a material adverse effect on our business, financial condition and results of operations.

On September 8, 2016, Chilean Law No. 20,940 was published and modified the Labor Code by introducing, among other things, changes to the formation of trade unions, the election of inter-company union delegates, the presence of women on union boards, anti-union practices and related sanctions, and collective negotiations. Due to these changes to the labor regulations, we may face an increase in our expenses that may have a significant adverse effect on our business, financial condition, and results of operations.

## Lawsuits and arbitrations could adversely impact us

We are party to a range of lawsuits and arbitrations involving different matters as described in Note 22.1 of our Consolidated Financial Statements. Although we intend to defend our positions vigorously, our defense of these actions may not be successful and responding to such lawsuits and arbitrations diverts our management’s attention from day-to-day operations. Adverse judgments or settlements in these lawsuits may have a material adverse effect on our business, financial condition and results of operations. In addition, our strategy of being a world leader includes entering into commercial and production



alliances, joint ventures and acquisitions to improve our global competitive position. As these operations increase in complexity and are carried out in different jurisdictions, we may be subject to legal proceedings that, if settled against us, could have a material adverse effect on our business, financial condition and results of operations.

## We have operations in multiple jurisdictions with differing regulatory, tax and other regimes

We operate in multiple jurisdictions with complex regulatory environments that are subject to different interpretations by companies and respective governmental authorities. These jurisdictions may have different tax codes, environmental regulations, labor codes and legal framework, which adds complexity to our compliance with these regulations. Any failure to comply with such regulations could have a material adverse effect on our business, financial condition and results of operations.

## Environmental laws and regulations could expose us to higher costs, liabilities, claims and failure to meet current and future production targets

Our operations in Chile are subject to national and local regulations relating to environmental protection. In accordance with such regulations, we are required to conduct environmental impact studies or statements before we conduct any new projects or activities or significant modifications of existing projects that could impact the environment or the health of people in the surrounding areas. We are also required to obtain an environmental license for certain projects and activities. The Environmental Evaluation Service (Servicio de Evaluación Ambiental) evaluates environmental impact studies submitted for its approval. The public, government agencies or local authorities may review and challenge projects that may adversely affect the environment, either before these projects are executed or once they are operating, if they fail to comply with applicable regulations. In order to ensure compliance with environmental regulations, Chilean authorities may impose fines up to approximately US$9 million per infraction, revoke environmental permits or temporarily or permanently close facilities, among other enforcement measures.

Chilean environmental regulations have become increasingly stringent in recent years, both with respect to the approval of new projects and in connection with the implementation and development of projects already approved, and we believe that this trend is likely to continue. Given public interest in environmental enforcement matters, these regulations or their application may also be subject to political considerations that are beyond our control.

We regularly monitor the impact of our operations on the environment and on the health of people in the surrounding areas and have, from time to time, made modifications to our facilities to minimize any adverse impact. Future developments in the creation or implementation of environmental requirements or their interpretation could result in substantially increased capital, operation or compliance costs or otherwise adversely affect our business, financial condition and results of operations.

The success of our current investments at the Salar de Atacama and Nueva Victoria is dependent on the behavior of the ecosystem variables being monitored over time. If the behavior of these variables in future years does not meet environmental requirements, our operation may be subject to important restrictions by the authorities on the maximum allowable amounts of brine and water extraction. For example, on December 13, 2017, the First Environmental Court of Antofagasta ordered the temporary and partial closure of certain water extraction wells located in the Salar de Llamara. These wells allow the Company to extract approximately 124 liters per second of water, almost 15% of the water used in the Company’s operations in the First Region of Chile for iodine and nitrate production. In October 2018, the First Environmental Court of Antofagasta, accepted the Company’s claim, and dismissed the restrictions without prejudice. It is possible that third parties could seek to reinstate these restrictions in the future.



Our future development depends on our ability to sustain future production levels, which requires additional investments and the submission of the corresponding environmental impact studies or statements. If we fail to obtain approval or required environmental licenses, our ability to maintain production at specified levels will be seriously impaired, thus having a material adverse effect on our business, financial condition and results of operations.

In addition, our worldwide operations are subject to international and other local environmental regulations. Since environmental laws and regulations in the different jurisdictions in which we operate may change, we cannot guarantee that future environmental laws, or changes to existing environmental laws, will not materially adversely impact our business, financial condition and results of operations.

## Our water supply could be affected by geological changes or climate change

Our access to water may be impacted by changes in geology, climate change or other natural factors, such as wells drying up or reductions in the amount of water available in the wells or rivers from which we obtain water, that we cannot control. Any such change may have a material adverse effect on our business, financial condition and results of operations.

## Any loss of key personnel may materially and adversely affect our business

Our success depends in large part on the skills, experience and efforts of our senior management team and other key personnel. The loss of the services of key members of our senior management or employees with critical skills could have a negative effect on our business, financial condition and results of operations. If we are not able to attract or retain highly skilled, talented and qualified senior managers or other key personnel, our ability to fully implement our business objectives may be materially and adversely affected.

A significant percentage of our shares are held by two principal shareholder groups who may have an interest that is different from that of other shareholders and of each other. Any change in such principal shareholder groups may result in a change of control of the Company or of its Board of Directors or its management, which may have a material adverse effect on our business, financial condition and results of operations

As of December 5, 2018, two principal shareholder groups held in the aggregate 55.77% of the total outstanding shares of SQM, including a majority of our Series A common shares, and have the power to elect seven of our eight directors. The interests of the two principal shareholder groups may in some cases differ from those of other shareholders and of each other.

One principal shareholder group is the Pampa Group, as defined in “Section 4) Ownership and Shares”, which currently owns 32% of the total outstanding shares of SQM. Until November 30, 2018, the CMF considered the Pampa Group the controller of SQM. On this date, the CMF determined that in accordance with the distribution of the shares of SQM, “the Pampa Group does not exert decisive power over the management of the Company, and is therefore not considered a controlling shareholder. The CMF could change its decision in the future if circumstances change.

Nutrien (formerly PCS before the merger with Agrium Inc. on January 1, 2018) was one of the principal shareholders of the Company. On December 5, 2018, Inversiones TLC SpA, a subsidiary of Tianqi Lithium Corporation (“Tianqi”), acquired the shares of SQM held by Nutrien through Inversiones El Boldo Limitada, Inversiones PCS Chile Limitada and Inversiones RAC Chile, representing 23.77% of the total shares of SQM. Tianqi currently owns 23.77% of the total outstanding shares of SQM.

The divestiture by the Pampa Group or Tianqi, or potential changes in the circumstances that have led to the determination of the CMF related to the controller status of the shareholders of the Company, or a



combination thereof, may have a material adverse effect on our business, financial condition and results of operations.

Tianqi is a significant shareholder and a competitor of the Company, which can increase the risks of competition.

Tianqi is a competitor in the lithium business, and as a result of the number of shares that its owns of the Company, it has the right to choose up to three Board members. On August 27, 2018, Tianqi and the Chilean antitrust regulator (the Chilean National Economic Prosecutor’s Office, or FNE for its initials in Spanish), entered into an extrajudicial settlement agreement, under which complemented certain restrictive measures in order to (i) maintain the competitive conditions of the lithium market, (ii) mitigate the risks described in the agreement and (iii) limit Tianqi’s access to certain information of the Company and its subsidiaries, which are defined as “sensitive information” under in the agreement.

During the approval process of the extrajudicial agreement before the FNE, the Company expressed its concerns regarding the measures contained in the extrajudicial agreement since (i) it could not effectively resolve the risks that Tianqi and the FNE have sought to mitigate, (ii) they are not correctly oriented to avoid the access to the Company’s “sensitive information” that, in the possession of a competitor, could harm the Company and the proper functioning of the market and (iii) it could contradict the Corporation Law in Chile.

The presence of a shareholder which is at the same time a competitor of the Company and the right of this competitor to choose Board members, could generate risks to free competition and/or increase the risks of an investigation of free competition against the Company, whether in Chile or in other countries, all of which could have an adverse material effect in our business.

Our information technology systems may be vulnerable to disruption which could place our systems at risk from data loss, operational failure, or compromise of confidential information.

We rely on various computer and information technology systems, and on third party developers and contractors, in connection with our operations, including two networks that link our principal subsidiaries to our operating and administrative facilities in Chile and other parts of the world and ERP software systems, which are used mainly for accounting, monitoring of supplies and inventories, billing, quality control, research activities, and production process and maintenance control. In addition, we use Cloud technologies to support new business processes related to the Internet of Things (IoT) and Advanced Analytics, which allow us to collect information enabling us to advance the predictive short-term and medium-term analysis of our production process and its possible automation in the long term. Our information technology systems are susceptible to disruption, damage or failure from a variety of sources, including errors by employees or contractors, computer viruses, cyber-attacks, misappropriation of data by outside parties, and various other threats. We have taken certain measures to identify and mitigate these risks, including conducting a cybersecurity review and initiating process automation and digitalization projects at various sites with the object of reducing operational risk and improving security and operational efficiency, which also includes modernization of existing information technology infrastructure and communications systems. However, we cannot guarantee that due to the increasing sophistication of cyber-attacks our systems will not be compromised and because we do not maintain specialized cybersecurity insurance, our insurance coverage for protection against cybersecurity risk may not be sufficient. Cybersecurity breaches could result in losses of assets or production, operational delays, equipment failure, inaccurate recordkeeping, or disclosure of confidential information, any of which could result in business interruption, reputational damage, lost revenue, litigation, penalties or additional expenses and could have a material adverse effect on our business, financial condition and results of operations.



## Risks Relating to Financial Markets

## Currency fluctuations may have a negative effect on our financial performance

We transact a significant portion of our business in U.S. dollars, and the U.S. dollar is the currency of the primary economic environment in which we operate. In addition, the U.S. dollar is our functional currency for financial statement reporting purposes. A significant portion of our costs, however, is related to the Chilean peso. Therefore, an increase or decrease in the exchange rate between the Chilean peso and the U.S. dollar would affect our costs of production. The Chilean peso has been subject to large devaluations and revaluations in the past and may be subject to significant fluctuations in the future. As of December 31, 2018, the Chilean peso exchange rate was Ch$694.77 per U.S. dollar, while as of December 31, 2017, the Chilean peso exchange rate was Ch$614.75 per U.S. dollar. The Chilean peso therefore depreciated against the U.S. dollar by 13% in 2018.

As an international company operating in several other countries, we also transact business and have assets and liabilities in other non-U.S. dollar currencies, such as, among others, the Euro, the South African rand, the Mexican peso, the Chinese yuan, the Thai baht and the Brazilian real. As a result, fluctuations in the exchange rates of such foreign currencies to the U.S. dollar may have a material adverse effect on our business, financial condition and results of operations.

## Interest rate fluctuations may have a material impact on our financial performance

As of December 31, 2018, we had US$70 million of outstanding short and long-term debt bearing interest based on LIBOR. A relative increase in the rate could materially impact our business, financial condition and results of operations.

## Risks Relating to Chile

## As we are a company based in Chile, we are exposed to Chilean political risks

Our business, results of operations, financial condition and prospects could be affected by changes in policies of the Chilean government, other political developments in or affecting Chile, legal changes in the standards or administrative practices of Chilean authorities or the interpretation of such standards and practices, over which we have no control.

Changes in regulations regarding, or any revocation or suspension of our concessions could negatively affect our business

Any changes to regulations to which we are subject or adverse changes to our concession rights, or a revocation or suspension of our concessions, could have a material adverse effect on our business, financial condition and results of operations.

## Changes in mining or port concessions could affect our operating costs

We conduct our mining operations, including brine extraction, under exploitation and exploration concessions granted in accordance with provisions of the Chilean constitution and related laws and statutes. Our exploitation concessions essentially grant a perpetual right (with the exception of the rights granted to SQM Salar with respect to the Salar de Atacama concessions under the Lease Agreement described above, which expires in 2030) to conduct mining operations in the areas covered by the concessions, provided that we pay annual concession fees. Our exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time and to subsequently request a corresponding exploitation concession.



We also operate port facilities at Tocopilla, Chile, for the shipment of products and the delivery of raw materials pursuant to maritime concessions, which have been granted under applicable Chilean laws and are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

Any significant adverse changes to any of these concessions could have a material adverse effect on our business, financial condition and results of operations.

## Changes in water rights laws and other regulations could affect our operating costs

We hold water use rights that are key to our operations. These rights were obtained from the Chilean Water Authority (Dirección General de Aguas) for supply of water from rivers and wells near our production facilities, which we believe are sufficient to meet current operating requirements. However, the Chilean Water Rights Code (Código de Aguas or the “Water Code”) is subject to changes, which could have a material adverse impact on our business, financial condition and results of operations. For example, a series of bills are currently being discussed at the Chilean National Congress that seek to desalinate seawater for use in mining production processes, amend the Mining Code for water use in mining operations, amend the Political Constitution on water and introduce changes to the regulatory framework governing the terms of inspection and sanction of water. As a result, the amount of water that we can actually use under our existing rights may be reduced or the cost of such use could increase. These and potential future changes to the Water Code or other relevant regulations could have a material adverse effect on our business, financial condition and results of operations.

## The Chilean government could levy additional taxes on corporations operating in Chile

In Chile, there is a royalty tax that is applied to mining activities developed in the country.

On September 29, 2014, Law No. 20,780 was published (the “Tax Reform”), introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. As a result of these reforms, open stock corporations like SQM are subject to the partially integrated shareholder tax regime (sistema parcialmente integrado). The corporate tax rate applicable to us increased to 25.5% in 2017 and increased to the maximum rate of 27% in 2018.

Under the partially integrated shareholder taxation regime, shareholders bear the tax on dividends upon payment, but they will only be permitted to credit against such shareholder taxes a portion of the Chilean corporate tax paid by us on our earnings, unless the shareholder is resident in a country with a tax treaty in force with Chile. In that case, 100% of the Chilean corporate tax paid by us may be credited against the final taxes at the shareholder level.

As a result, foreign shareholders resident in a non-treaty jurisdiction will be subject to a higher effective tax rate than residents of treaty jurisdictions. There is a temporary rule in effect from January 1, 2017 through December 31, 2019 that treaty jurisdictions for this purpose will include jurisdictions with tax treaties signed with Chile prior to January 1, 2017, whether or not such treaties are in force. This is currently the status of the treaty signed between Chile and United States. After December 31, 2019, if no treaty is in effect, shareholders in those jurisdictions will be subject to a higher effective tax rate.

The Tax Reform tax increase prompted a US$52.3 million increase in our deferred tax liabilities as of December 31, 2014. In accordance with IAS 12, the effects generated by the change in the income tax rate approved by the Tax Reform on income and deferred taxes were applied to the income statement. For purposes of the Company’s statutory consolidated financial statements filed with the CMF, in accordance with the instructions issued by the CMF in its circular 856 of October 17, 2014, the effects generated by



the change in the income tax rate were accounted for as retained earnings. The amount charged to equity as of December 31, 2014 was US$52.3 million, thereby giving rise to a difference of US$52.3 million in profit for the year and income tax expense as presented in the Company’s 2014 audited consolidated financial statements in its annual report on Form 20-F compared with profit and income tax expense as presented in the Company’s 2014 statutory consolidated financial statements filed with the CMF.

In addition, the Tax Reform may have other material adverse effects on our business, financial condition and results of operations. Likewise, we cannot assure you that the manner in which the Royalty Law (as defined below) or the corporate tax rate are interpreted and applied will not change in the future. The Chilean government may decide to levy additional taxes on mining companies or other corporations in Chile. Such changes could have a material adverse effect on our business, financial condition and results of operations.

Ratification of the International Labor Organization’s Convention 169 concerning indigenous and tribal peoples might affect our development plans

Chile, a member of the International Labor Organization (“ILO”), has ratified the ILO’s Convention 169 (the “Indigenous Rights Convention”) concerning indigenous and tribal people. The Indigenous Rights Convention established several rights for indigenous people and communities. Among other rights, the Indigenous Rights Convention states that (i) indigenous groups should be notified and consulted prior to the development of any project on land deemed indigenous, although veto rights are not mentioned, and (ii) indigenous groups have, to the extent possible, a stake in benefits resulting from the exploitation of natural resources in indigenous land. The extent of these benefits has not been defined by the Chilean government. The Chilean government has addressed item (i) above through Supreme Decree No. 66, issued by the Social Development Ministry. This decree requires government entities to consult indigenous groups that may be directly affected by the adoption of legislative or administrative measures, and it also defines criteria for the projects or activities that must be reviewed through the environmental evaluation system that also require such consultation. To the extent that the new rights outlined in the Indigenous Rights Convention become laws or regulations in Chile, judicial interpretations of the convention of those laws or regulations could affect the development of our investment projects in lands that have been defined as indigenous, which could have a material adverse effect on our business, financial condition and results of operations.

## Chile is located in a seismically active region

Chile is prone to earthquakes because it is located along major fault lines. The most recent major earthquakes in Chile, which occurred in April 2017 in the Valparaíso region and in December 2016 in Chiloé Island, had a magnitude of 6.9 and 7.6, respectively, on the Richter scale. There were also earthquakes in 2015, 2014 and 2010 that caused substantial damage to some areas of the country. Chile has also experienced volcanic activity. A major earthquake or a volcanic eruption could have significant negative consequences for our operations and for the general infrastructure, such as roads, rail, and access to goods, in Chile. Although we maintain industry standard insurance policies that include earthquake coverage, we cannot assure you that a future seismic or volcanic event will not have a material adverse effect on our business, financial condition and results of operations.

## Risks Relating to our Shares and to our ADSs

The price of our ADSs and the U.S. dollar value of any dividends will be affected by fluctuations in the U.S. dollar/Chilean peso exchange rate

Chilean trading in the shares underlying our ADSs is conducted in Chilean pesos. The depositary will receive cash distributions that we make with respect to the shares in Chilean pesos. The depositary will convert such Chilean pesos to U.S. dollars at the then prevailing exchange rate to make dividend and other



distribution payments in respect of ADSs. If the value of the Chilean peso falls relative to the U.S. dollar, the value of the ADSs and any distributions to be received from the depositary will decrease.

Developments in other emerging markets could materially affect the value of our ADSs and our shares

The Chilean financial and securities markets are, to varying degrees, influenced by economic and market conditions in other emerging market countries or regions of the world. Although economic conditions are different in each country or region, investor reaction to developments in one country or region can have significant effects on the securities of issuers in other countries and regions, including Chile and Latin America. Events in other parts of the world may have a material effect on Chilean financial and securities markets and on the value of our ADSs and our shares.

The volatility and low liquidity of the Chilean securities markets could affect the ability of our shareholders to sell our ADSs

The Chilean securities markets are substantially smaller, less liquid and more volatile than the major securities markets in the United States. The volatility and low liquidity of the Chilean markets could increase the price volatility of our ADSs and may impair the ability of a holder to sell our ADSs into the Chilean market in the amount and at the price and time the holder wishes to do so.

Our share or ADS price may react negatively to future acquisitions and investments

As world leaders in our core businesses, part of our strategy is to look for opportunities that will allow us to consolidate and strengthen our competitive position in jurisdictions in which we currently do not operate. Pursuant to this strategy, we may carry out acquisitions or joint ventures relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. Depending on our capital structure at the time of such acquisitions or joint ventures, we may need to raise significant debt and/or equity which will affect our financial condition and future cash flows. Any change in our financial condition could affect our results of operations, negatively impacting our share or ADS price.

## ADS holders may be unable to enforce rights under U.S. Securities Laws

Because we are a Chilean company subject to Chilean law, the rights of our shareholders may differ from the rights of shareholders in companies incorporated in the United States, and ADS holders may not be able to enforce or may have difficulty enforcing rights currently in effect under U.S. federal or state securities laws.

Our Company is an open stock corporation incorporated under the laws of the Republic of Chile. Most of our directors and officers reside outside the United States, principally in Chile. All or a substantial portion of the assets of these persons are located outside the United States. As a result, if any of our shareholders, including holders of our ADSs, were to bring a lawsuit against our officers or directors in the United States, it may be difficult for them to effect service of legal process within the United States upon these persons. Likewise, it may be difficult for them to enforce judgments obtained in United States courts based upon the civil liability provisions of the federal securities laws in the United States against them in the United States.

In addition, there is no treaty between the United States and Chile providing for the reciprocal enforcement of foreign judgments. However, Chilean courts have enforced judgments rendered in the United States, provided that the Chilean court finds that the United States court respected basic principles of due process and public policy. Nevertheless, there is doubt as to whether an action could be brought successfully in Chile in the first instance on the basis of liability based solely upon the civil liability provisions of the United States federal securities laws.



As preemptive rights may be unavailable for our ADS holders, they have the risk of their holdings being diluted if we issue new stock

Chilean laws require companies to offer their shareholders preemptive rights whenever issuing new shares of capital stock so shareholders can maintain their existing ownership percentage in a company. If we increase our capital by issuing new shares, a holder may subscribe for up to the number of shares that would prevent dilution of the holder’s ownership interest.

If we issue preemptive rights, United States holders of ADSs would not be able to exercise their rights unless a registration statement under the Securities Act were effective with respect to such rights and the shares issuable upon exercise of such rights or an exemption from registration were available. We cannot assure holders of ADSs that we will file a registration statement or that an exemption from registration will be available. We may, in our absolute discretion, decide not to prepare and file such a registration statement. If our holders were unable to exercise their preemptive rights because we did not file a registration statement, the depositary bank would attempt to sell their rights and distribute the net proceeds from the sale to them, after deducting the depositary’s fees and expenses. If the depositary could not sell the rights, they would expire and holders of ADSs would not realize any value from them. In either case, ADS holders’ equity interests in us would be diluted in proportion to the increase in our capital stock.

If we were classified as a Passive Foreign Investment Company by the U.S. Internal Revenue Service, there could be adverse consequences for U.S. investors

We believe that we were not classified as a Passive Foreign Investment Company (“PFIC”) for 2018. Characterization as a PFIC could result in adverse U.S. tax consequences to you if you are a U.S. investor in our shares or ADSs. For example, if we (or any of our subsidiaries) are a PFIC, our U.S. investors may become subject to increased tax liabilities under U.S. tax laws and regulations and will become subject to burdensome reporting requirements. The determination of whether or not we (or any of our subsidiaries or portfolio companies) are a PFIC is made on an annual basis and will depend on the composition of our (or their) income and assets from time to time.

## Changes in Chilean tax regulations could have adverse consequences for U.S. investors

Currently cash dividends paid by us to foreign shareholders are subject to a 35% Chilean withholding tax. When the Company pays a corporate income tax on the income from which the dividend is paid, known as a “First Category Tax”, a credit for the full amount of the First Category Tax effectively reduces the rate of Withholding Tax. Changes in Chilean tax regulations could have adverse consequences for U.S. investors.

## 3) F) DESCRIPTION OF BUSINESS ENVIRONMENT: CAPITAL EXPENDITURE PROGRAM

We regularly review different opportunities to improve our production methods, reduce costs, increase production capacity of existing products and develop new products and markets. Additionally, significant capital expenditures are required every year in order to sustain our production capacity. We are focused on developing new products in response to identified customer demand, as well as new products that can be derived as part of our existing production or other products that could fit our long-term development strategy. Our capital expenditures in Chile have been mainly related to the organic growth and sustainability of our business, including the construction of new facilities and the renovation of plants and equipment. From 2016, we began to invest in lithium projects outside Chile, starting with the Minera Exar project in Argentina and continuing with Mount Holland project in Australia in 2017. In 2018, we sold our stake in Minera Exar and continued the development of the Mount Holland project. We also expanded our lithium carbonate capacity in Chile, reaching capacity 70,000 metric tons per year.



Our capital expenditures for the years ended December 31, 2018, 2017 and 2016 were as follows:

<table><tr><td>(in millions of U.S. dollars)</td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Capital Expenditures</td><td>244.7</td><td>142.1</td><td>131.3</td></tr></table>

During 2018, we had total capital expenditure of US$244.7 million, primarily related to:

- Capacity expansion projects related to increasing lithium carbonate production to 70,000 metric tons per year and lithium hydroxide production to 13,500 metric tons per year in Chile;

• Investments to increase iodine capacity to 14,000 in the Nueva Victoria mine;

- Capacity expansion project related to potassium nitrate production plants III and IV in Coya Sur; and

- General maintenance of all production units and the Port of Tocopilla in order to ensure the fulfillment of production and sales targets.

During 2017, we had total capital expenditures of US$142.1 million, primarily related to:

- Capacity expansion projects related to lithium carbonate and lithium hydroxide production in Chile;

- Investments in mining workshop and operations centers to relocate operations from Nueva Victoria mine to mining sector Tente en el Aire;

• Capacity expansion project related to potassium nitrate production;

- General maintenance of all production units and Tocopilla port in order to ensure the fulfillment of production and sales targets.

During 2016, we had total capital expenditures of US$131.3 million, primarily related to:

- Completion of the project related to the expansion of ponds at Nueva Victoria to increase the production of iodine and nitrates;

• Capacity expansion projects related to our potassium nitrate production;

• Capacity expansion project related to our lithium hydroxide production;

• Improvements in the open storage areas at the Port of Tocopilla;

- General maintenance of all production units in order to ensure the fulfillment of production targets and the safety of all of our employees.

The Board of Directors has approved a capital expenditure framework for 2019 of approximately US$360 million focused on the maintenance of our production facilities in order to strengthen our ability to meet our production goals and to increase our production capacity, primarily related to lithium carbonate capacity expansion and nitrates capacity in Chile and development of lithium project in Australia. We expect our installed capacity of lithium carbonate in Chile to reach approximately 120,000 metric tons by the end of 2020, an increase of 50,000 metric tons compared to our current capacity of 70,000 metric tons. From that point, we will continue to work to reach an installed capacity of 180,000 metric tons in Chile in the future. The capital expenditure associated with this expansion is expected to be in the range of approximately US$4,000 per ton. We expect to complete the feasibility study related to the Mount Holland lithium project in Australia in the second half of 2019, at which time we believe we will have a better estimate associated with the capital expenditure and costs of the project.

We do not expect that our 2019 capital investment program will require external financing. However, we always have the option to access capital markets in order to optimize our financial position.



## 4) OWNERSHIP AND SHARES

## 4) A) OWNERSHIP AND SHARES: OWNERSHIP

## i) OWNERSHIP CONTROL SITUATION

At December 31, 2017, SQM does not have a “controlling group” as such term is defined in Title XV of Chilean Law No. 18,045.

## ii) IDENTIFICATION OF NON-CONTROLLING MAJORITY SHAREHOLDERS

SQM has been informed that, as of December 31, 2018, Mr. Julio Ponce Lerou (ID No. 4.250.719-9) and related persons control 100% of Inversiones SQYA Ltda. (“SQYA”) and 100% of Inversiones SQ Ltda. These two companies control indirectly 32.00% of all shares of SQM (consisting of 71,871,838 Series A shares and 12,341,049 Series B shares), as follows: (i) Inversiones SQ Ltda. controls 0.0258% of Norte Grande S.A.

## v) SIGNIFICANT CHANGES IN SHARE OWNERSHIP

Nutrien Ltd., which was one of the main shareholder groups with 32% of SQM's total shares as of December 31, 2017, divested all its ownership in SQM during 2018. This was through the sale of its Series B shares on the Chilean securities market in May 2018, and a sale of its Series A shares on the Chilean securities market to Inversiones TLC SpA, a subsidiary of Tianqi Lithium Corporation, in December 2018. As of December 31, 2018, Nutrien Ltd. had 0% of the total shares of SQM, and Inversiones TLC SpA had 23.77% of the total shares issued by SQM.

Until November 30, 2018, the Pampa Group was considered by the CMF as the Company's controller. However, starting from that date, the CMF determined that in accordance with the distribution of the shares of SQM, “the Pampa Group does not exert decisive power over the management of the Company, and is therefore not considered a controlling shareholder”. The CMF could change its decision in the future if circumstances change.

Tianqi Settlement Agreement with the Chilean National Economic Prosecutor’s Office (the “FNE”)

In August 2018, after an investigation by the FNE in connection with the proposed acquisition by Tianqi of 23.77% of the Company’s shares, Tianqi and the FNE entered into an extrajudicial settlement agreement (the “Settlement Agreement”) which implemented certain restrictive measures in order to (i) maintain the competitive conditions of the lithium market, (ii) mitigate the risks described in the Settlement Agreement and (iii) limit Tianqi’s access to certain information of the Company and its subsidiaries, which are defined as sensitive under the Settlement Agreement (“Sensitive Information”) (collectively, the “Purpose”). Pursuant to the Settlement Agreement, Tianqi agreed that, among other things:

- Tianqi will not nominate any of its directors, executives or employees to the SQM Board of Directors;

- Tianqi and the directors nominated by it will not influence or intervene for the benefit of Tianqi and prejudice the interests of SQM;

- The directors nominated by Tianqi will not participate nor will they be part of any committees, the management or other decision-making bodies related to lithium of SQM or of any companies controlled by SQM, unless nominated by independent directors;

- Tianqi will inform the FNE of any agreement in the lithium market, with Albemarle and/or SQM, prior to its execution;

- Tianqi will notify the FNE of any event from which it acquires control or decisive influence in SQM;

- Tianqi will disassociate any director, executive or employee appointed by third parties, who assumes a position described above in SQM;

- Tianqi will not request access to commercially sensitive information from SQM;

- The directors nominated by Tianqi will not disclose commercially sensitive information of SQM;

- The directors nominated by Tianqi will personally bind themselves to the obligations assumed by Tianqi with the FNE; and

- Tianqi will report to the FNE the appointments and periodic compliance with its obligations.

The restrictions will remain in place for a period of six years.

During the approval process for the Settlement Agreement before the FNE, the Company expressed its concerns to the Chilean Antitrust Court regarding the measures contained in the Settlement Agreement since (i) it could not effectively resolve the risks that Tianqi and the FNE sought to mitigate, (ii) the restrictions are not correctly oriented to avoid the access to Sensitive Information that, in the possession of a competitor, could damage the Company and the proper functioning of the market and (iii) it could contradict the Chilean Corporations Act (Law No. 18,046 on Corporations). The Settlement Agreement



was approved in October 2018 by the Chilean Antitrust Court. A copy of the Settlement Agreement, in Spanish, has been made publicly available on the Company’s website at http://ir.sqm.com/English/investor-relation/press-releases/press-release-details/2018/Agreement-between-FNE-and-Tianqi-LIthium/default.aspx and is also available on the FNE’s website at http://www.fne.gob.cl/wp-content/uploads/2018/09/Acuerdo-Etrajudicial-FNE-Tianqi-con-firma-27.08.18.pdf.

On January 23, 2019, the Board of Directors of the Company approved a protocol for the presentation and use of sensitive information in the Board of Directors that is described in Note 34.2 of our Consolidated Financial Statements.

## 4) B) OWNERSHIP STRUCTURE AND SHARES: SHARES AND THEIR CHARACTERISTICS AND RIGHTS

## i) DESCRIPTION OF SERIES OF SHARES

Dividends are annually distributed to the Series A and Series B shareholders of record on the fifth business day prior to the date for payment of the dividends. The By-laws do not specify a time limit after which dividend entitlement elapses but Chilean regulations establish that after 5 years, unclaimed dividends are to be donated to the Chilean Fire Department.

Article 5 of the Company’s By-laws establishes that Series B shares may in no case exceed fifty percent of the issued, outstanding and paid shares of SQM. Series B shares have a restricted right to vote as they can only elect one Director of the Company, regardless of their capital stock’s share. Series B shares have the right to call for an Ordinary or Extraordinary Shareholders’ Meeting when the shareholders of at least 5% of the Series B shares request so and to call for an Extraordinary Board of Directors Meeting without the Chairman’s authorization when it is requested by the Director elected by the shareholders of the Series B shares. Series A shares have the option to exclude the Director elected by Series B shareholders from the voting process in which the Chairman of the Board is to be elected, if there is a tie in the first voting process. Articles 31 and 31 bis of the Company’s By-laws establish that in General Shareholders’ Meetings each shareholder will have a right to one vote for each share he owns or represents and (a) that no shareholder will have the right to vote for himself or on behalf of other shareholders of the same Series A or Series B shares representing more than 37.5% of the total outstanding shares with right to vote of each Series and (b) that no shareholder will have the right to vote for himself or on behalf of other shareholders representing more than 32% of the total outstanding shares with a right to vote. In calculating a single shareholder’s ownership of Series A or B shares, the shareholder’s stock and those pertaining to third parties related to them are to be added.

Article 5 bis of the Company’s By-laws establishes that no person may directly or by means of related third persons concentrate more than 32% of the Company’s total shares with right to vote.

Each Series A share and Series B share is entitled to share equally in the Company’s profits, i.e., they have the same rights on any dividends declared on the outstanding shares of SQM.

The Company By-laws do not contain any provision relating to (a) redemption provisions (b) sinking funds or (c) liability to capital calls by the Company.

As established in article 103 of Law No. 18,046, a company subject to the supervision of the SVS may be liquidated in the following cases:

• Expiration of the duration term, if any, as established in its By-laws;



- All the shares end up in the possession of one individual for more than ten continuous days;

• By agreement of an Extraordinary Shareholders Meeting;

- By abolition, pursuant to applicable laws, of the decree that authorized its existence;

• Any other reason contemplated in its By-laws.

Article 40 of the Company’s By-laws states that in the event of liquidation, the Shareholders’ Meeting will appoint a three-member receiver committee that will have the authority to carry out the liquidation process. Any surplus will be distributed equally among the shareholders.

The only way to change the rights of the holders of the SQM shares is by modifying its By-laws, which can only be carried out by an Extraordinary Shareholders’ Meeting, as established in article 28 of the Company By-laws.

On May 17, 2018, an extraordinary shareholders’ meeting approved technical changes to the By-laws of SQM, as well as an amendment providing for a new “second transitory article” as follows:

“Throughout the period running from the date of the extraordinary shareholders’ meeting at which this transitory article is incorporated, and December 31, 2030, the restriction against voting on behalf of more than 37.5% of any series of shares in the Company, established in Article 31 hereof, shall be subject to the following exception, applicable only to the election of board members by means of Series A shares in the Company: If two or more persons, regardless of whether or not they are related parties to each other (the incoming shareholders), act prior to December 31, 2030 such as to acquire a sufficient number of Series A shares to allow them to hold voting powers for the selection of directors of the Company amounting to more than 37.5% of that series, then any registered shareholder or group of shareholders holding more than 37.5% of all Series A shares in the Company shall be entitled to vote for the selection of directors of the Company amounting to whichever is less, between a number of the Series A shares that are held (i) by existing shareholders as of that date, and (ii) by the incoming shareholders with voting rights. Similarly, if for any reason a registered shareholder in the Company as of the date hereof who holds more than 37.5% of Series A shares in the company between the date hereof and December 31, 2030, comes to hold more voting shares for the selection of directors of the Company than the votes allocated for holding 37.5% of said Series A shares, either through a joint action agreement with other shareholders, including existing shareholders, or by any other means, then any other shareholder or group of shareholders in the Company that is not a related party to the same and holds more than 37.5% of all voting Series A shares in the Company, including both existing and incoming shareholders, shall be entitled to vote for the selection of directors of the Company in accordance with whichever number of Series A shares in the Company is the lesser, between (i) the number held by this shareholder or group of shareholders, and (ii) the existing shareholder may have the capacity to vote in excess of the restriction amounting to 37.5% of said shares.”

Total number of shares:

• Series A: 142,819,552

• Series B: 120,376,972

## ii) DIVIDEND POLICY

SQM’s dividend policy for 2018, which was announced at the General Ordinary Shareholders’ Meeting on April 27, 2018, was to distribute to the SQM’s shareholders as a final dividend a percentage of our net income that is determined as per following financial parameters:

- 100% of the 2018 net income, when the following financial parameters are met: (a) the total sum of cash and cash equivalent, and other current financial assets (“Cash”) divided by the total sum of the current financial liabilities (“Current Financial Liabilities”) is equal to or greater than 2.5



times, and (b) the total sum of the current liabilities and the non-current liabilities (“Total Liabilities”) divided by the total sum of the equity (“Equity”) is equal to or less than 1.1 times.

80% of the 2018 net income when the following financial parameters are met: (a) Cash divided by Current Financial Liabilities is equal to or greater than 2.0 times, and (b) the total sum of the Total Liabilities divided by the total Equity is equal to or less than 1.2 times.

60% of the 2018 net income when the following financial parameters are met: (a) Cash divided by Current Financial Liabilities is equal to or greater than 1.5 times, and (b) Total Liabilities divided by Equity is equal to or less than 1.3 times.

If none of the foregoing financial parameters are met, the Company shall distribute and pay, as a final dividend, and in favor of the respective shareholders, 50% of the 2018 net income.

According to the dividend policy for 2018, the dividends are distributed and paid during 2018, in the form of three interim dividends (dividendos provisorios) that will be charged against the final dividend. At the ordinary shareholders meeting that will be held in 2019, the Board of Directors shall propose a final dividend pursuant to the financial parameters expressed above, discounting the total amount of the interim dividends previously distributed during 2018.

On May 23, 2017, the Board of Directors agreed to pay and distribute on June 15, 2018 a provisional dividend of US$114 million, equivalent to US$0.43247 per share, to be charged against the 2018 net income.

On August 22, 2017, the Board of Directors agreed to pay and distribute on September 12, 2018 a provisional dividend of US$134 million, equivalent to US$0.50864 per share, to be charged against the 2018 net income.

On November 21, 2017, the Board of Directors agreed to pay and distribute on December 12, 2018 a provisional dividend of US$84 million, equivalent to US$0.31726 per share, to be charged against the 2018 net income.

## 8) INFORMATION ABOUT RELEVANT OR ESSENTIAL FACTS

## Relevant or Essential Facts Pertaining to SQM S.A.

The following events occurred or were reported as essential events or events of interest to the CMF, the Stock Exchanges and included on the Company’s website:

On January 17, 2018, it was informed that today SQM and CORFO (Corporación de Formento de la Producción) reached an agreement to end the arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in the case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce (Centro de Arbitrajes y Mediación de la Cámara de Comercio de Santiago) and other cases accumulated to it (the “Agreement”). The Agreement has been reached within the conclusion process of the arbitration and on the basis presented by the arbitrator to the parties. Both SQM’s Board of Directors and the Board of CORFO have approved the Agreement.

The Agreement includes a total payment of US$17.5 million plus agreed interest which a subsidiary of SQM, SQM Salar S.A. ("SQM Salar"), shall pay CORFO. This payment does not imply the recognition of having owed any amount to CORFO, and has been agreed to with the sole purpose of ending the disputes between the parties.

Additionally, the Agreement includes important amendments to the lease agreement and project agreement signed between CORFO and SQM in 1993, which are the contracts that currently permit the mining operations of SQM Salar in the Salar de Atacama (the "Contracts"). The main modifications are detailed below, and will become effective once the following resolutions have been issued: (i) the approval resolution of the Contracts by the CORFO Council, and (ii) the resolution that executes the respective approval agreement by the Chilean Nuclear Energy Commission (CCHEN):

(a) An increase in lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama:

- In regard to lithium carbonate, the current rate of 6.8% on FOB sales shall be changed to the following structure of progressive rates based on the final sale price:

<table><tr><td>Price US\(/MT Li2CO3</td><td>Lease payment rate</td></tr><tr><td>$0 - $4,000</td><td>6.8%</td></tr><tr><td>$4,000 - $5,000</td><td>8.0%</td></tr><tr><td>$5,000 - $6,000</td><td>10.0%</td></tr><tr><td>$6,000 - $7,000</td><td>17.0%</td></tr><tr><td>$7,000 - $10,000</td><td>25.0%</td></tr><tr><td>&gt; $10,000</td><td>40.0%</td></tr></table>

As an example and considering a price of US12,600 per metric ton (similar to the average price seen in the third quarter of 2017), the lease rate would have been equal to 19.14%.

- In regard to potassium chloride, the current rate of 1.8% on FOB sales shall be changed to the following structure of progressive rates based on the final sale price:

<table><tr><td>Price US\(/MT KCL</td><td>Lease payment rate</td></tr><tr><td>$0 - $300</td><td>3.0%</td></tr><tr><td>$300 - $400</td><td>7.0%</td></tr><tr><td>$400 - $500</td><td>10.0%</td></tr><tr><td>$500 - $600</td><td>15.0%</td></tr><tr><td>&gt; $600</td><td>20.0%</td></tr></table>



- Similarly, the lease rates associated with the other products (lithium hydroxide, potassium sulfate and others) shall have similar changes to those described in the previous products.

(b) SQM Salar commits to contribute (i) between US$10.8 and US$18.9 million per year to research and development efforts, (ii) between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and (iii) 1.7% of total annual sales of SQM Salar to the regional development. As an example and considering annualized SQM Salar’s revenues reported in the first nine months of 2017 (approximately US$1 billion), 1.7% of sales would have been approximately US$17 million.

(c) The authorization by CORFO to increase the production and sales of lithium products produced in the Salar de Atacama. Subject to prior authorization by CCHEN, the Agreement considers that SQM Salar will have the right to exploit, subject to compliance with other agreed conditions, process and sell during the term of the Agreement (until the end of 2030) up to 349,553 metric tons of lithium metallic equivalent in the addition to the approximately remaining 64,816 metric tons of lithium metallic equivalent from the originally authorized amount. The sum of the above amounts is equal to approximately 2.2 million metric tons of lithium carbonate equivalent.

(d) SQM Salar shall offer part of its lithium production (up to a maximum of 25%) at preferential price to value-added producers that will potentially develop in Chile, a price based on the lowest export market price equal in each case to the weighted average FOB price calculated on the 20% lower price of the volume exported by SQM Salar during the last 6 months available.

(e) SQM Salar shall strengthen its corporate governance, incorporating various audit, environmental control and coordination mechanisms with CORFO. For these purposes it will be necessary to modify the bylaws of SQM Salar, including among others: (i) to incorporate specific rules for the management of the company, in the form that two of the directors of SQM Salar are independent and meet the requirements established for independent directors of a public company and (ii) for the board of SQM Salar to designate a committee to monitor compliance with the Contracts and to establish the regulations that will govern this committee and its functions.

(f) Extensive regulation regarding the return of assets upon termination of the Contracts and granting purchase options, including: (i) the restitution of the assets that Corfo made available to SQM Salar under the Contracts, (ii) a purchase option for all or part of the water rights that SQM Salar or its related parties currently own or will obtain in the future, that benefit or are necessary for the exploitation, either currently or in the future of the mining concessions included in the Contracts (the "Mining Concessions"), (iii) a free transfer to CORFO of the easements, that benefit the Mining Concessions or the project, developed by SQM Salar, excluding the mining easements constituted in the Salar del Carmen, (iv) a purchase option on the assets that SQM Salar uses as productive facilities within the Mining Concessions and assets that benefit the project and that are located within the area of the Mining Concessions and within the area of 10 kilometers from the limit of the Mining concessions, (v) a purchase option on the mining concessions that SQM Salar or its related companies currently constitute or will constitute in the future within the area of 2 kilometers from the limit of the Mining Concessions.

(g) An option for SQM Salar to sell to CORFO the facilities that are necessary to increase the additional production and operation capacity related to the increased lithium quota. The exercise price of this option is the replacement value of the facilities including its economic depreciation.

(h) An option for CORFO to request from SQM the evaluation of a joint project with a state company for the joint exploitation of mining property in the Salar de Maricunga. SQM commits to participate in good faith in this



process, and if there is no agreement for the project after 4 years, SQM will not be obligated to continue such negotiations.

(i) SQM, SQM Salar and SQM Potasio S.A. are prohibited to (i) sell lithium brine extracted within the Mining Concessions, (ii) alienate and obstruct in any way, and enter into any act or contract that affects the restitution of the assets indicated in letter (f) above, (iii) extract brine from its mining rights area within 10 kilometers from the limit of the Mining Concessions, (iv) extract brine from its mining rights area within 2 kilometers from the limit of Mining Concessions for a period of 15 years from the termination of the Contracts, and (v) agree with other operators of the OMA mining rights of the Salar de Atacama on the ways of operating resulting in a joint or integrated management of both production sites, therefore ensuring that SQM’s operations will always be independent without facilitating operational information, commercial strategies, information systems or common applications and/or personnel, conventions or price and other agreements that by their nature may negatively affect the lease income of CORFO.

On January 24, 2018, it was informed that in its ordinary board meeting today, Joanne L. Boyes and Robert A. Kirkpatrick presented their resignation from the positions as directors of SQM. In the same session, the board of directors agreed to appoint Darryl Stann as the replacement of Joanne L. Boyes.

On January 26, 2018, it was informed that SQM and its subsidiaries SQM Salar S.A. and SQM Nitrates S.A. (the "Companies"), reached an agreement with the Public Prosecutor to put an end to the investigation of the alleged responsibility of the Companies' for the lack of supervision with respect to the payments to suppliers and entities that may have had links with the politically exposed persons between 2008 and 2015. This deferred prosecution agreement (suspension conditional) has been proposed by the Public Prosecutor, accepted by the Companies and approved by the 8th Court of Santiago.

Under the deferred prosecution agreement, the Companies have not admitted responsibility in the matter subject to the investigation.

The agreement, approved by the Court, implies that the Companies must pay an aggregate amount of (i) CLP$900,000,000 to the Chilean State, and (ii) CLP$1,650,000,000 to various charitable organizations. In addition, the Companies must provide the Public Prosecutor with a report on the enhancements to their compliance program, implemented in recent years, with special emphasis on the incorporation of best practices in various jurisdictions.

The agreement is subject to appeal proceedings and, in the absence of changes, it will put an end to an investigation that has lasted for about 3 years, in which the various agencies have carried out both administrative and judicial investigations and have widely recognized the cooperation provided by the Companies.

On February 19, 2018, it was informed that in the extraordinary board meeting today, Mark F. Fracchia was appointed as the replacement of Robert A. Kirkpatrick.

On August 13, 2018, it was informed that together with its subsidiary SQM Potasio S.A. (SQM Potasio) SQM has signed a contract (the “Contract”) with Minera Exar (Exar), Lithium Americas (TSX: LAC; NYSE: LAC) and GFL International Co. Ltd. (Ganfeng).

Pursuant to this Contract, (i) SQM Potasio will sell to Ganfeng its entire stake and irrevocable contributions in Exar, company which owns Caucharí-Olaroz lithium project in the Jujuy province of Argentina (the “Project”), (ii) Exar will prepay the total amount of the loans received from SQM Potasio; and (iii) Exar will pay SQM for the services it provided to Exar during the development of the Project. According to the Contract, SQM and SQM Potasio will receive an approximate amount of US$87.5 million. The Contract is subject to certain conditions and should close during the fourth quarter of this year.

In addition, SQM Potasio and a subsidiary of Ganfeng will sign an agreement in which a deferred amount of US$50 million will be paid to SQM Potasio, subject to compliance with certain product sales targets of the Project.

On August 16, 2018, SQM provided the following information in addition to the press release published on Monday, August 13, 2018:

1. On August 13, 2018, SQM Potasio S.A. (SQM Potasio) subscribed with Exar, GFL International Co. Ltd. (Ganfeng), and Lithium Americas Corp. (LAC), a contract called Transaction Agreement (the "Agreement"), pursuant to which (a) SQM Potasio shall sell to Ganfeng its entire shareholding and irrevocable contributions in Exar; (b) Exar shall pay SQM Potasio, in advance, all outstanding loans it received from this company; and (c) Exar shall pay SQM for the services rendered to Exar during the Project's development stage. Under the Agreement, SQM and SQM Potasio shall receive a total amount of US$87.5 million.

2. The Agreement is subject to the fact that by the expected date of October 31, 2018, and in any case, no later than December 31, 2018 (the "Closure"), certain conditions are met, which are determined by the parties as necessary for the operations indicated in above letters (a) to (c) to materialize. The aforementioned conditions include that, at Closure: (i) the declarations and guarantees granted by the parties at the signing of the Agreement are certain and true; (ii) Exar may continue to develop its business under its normal course; (iii) the Project continues to be developed under the approved budget; (iv) the applicable laws and conditions established in the Project permits are complied with; (v) SQM supports the Project in the period of transition until the Closure, in order to allow the conclusion of activities that are under its responsibility and will be available to clarify Project information to LAC; (vi) there are no laws, regulations, judicial processes, orders of authority, or any other that prevents, prohibits, or restricts the Closure; and (vii) the necessary approvals for the Closure are obtained, even when the parties declared not to have them.

3. SQM has promised, under the Agreement, to allow part of its personnel to be hired temporarily by Exar until December 31, 2018, to carry out field supervision work of the development activities and construction of the Project. In turn, after the Closure, SQM has promised that (i) during the first six months, part of its team of professionals in



the areas of hydrogeology and engineering, who know the Project (the "Experts"), be available to hold technical discussions related to the Project on a monthly basis; and (ii) that upon completion of the previous period and up to a period of three years after the Closure, the Experts are available to hold technical discussions related to the Project on a bi-monthly basis.

4. For its part, SQM also informed that SQM Potasio and a subsidiary of Ganfeng will subscribe a contract called Deferred Payment Agreement (the "DPA"), under which a deferred payment of US$50 million will be made to SQM Potasio, subject to compliance with certain sales goals. Pursuant to the Agreement, the DPA will be signed by the parties at Closure, and the payment to which SQM Potassium shall be entitled, will be due to the extent that Exar reaches cumulative sales of (i) 25,000 tons (measured in lithium carbonate equivalent) of the Project's lithium products, (ii) at a price of at least US$10,000 per ton.

5. In accordance with the foregoing, SQM estimates, as a financial effect at Closure (i) a cash inflow of US$87.5 million; and (ii) a post-tax income of approximately US$5.5 million. The payment to which SQM Potasio is entitled under the DPA, will only be accounted for and recognized in the financial statements of SQM, once said payment has been actually received.

On September 12, 2018, it was informed that as of today, the Company learned that as a result of not having incurred the mining exploration expenses required under the legal framework in 2015, the Warden’s Court of the Department of Mines, Industry Regulation and Safety of Western Australia has recommended not to accept exceptions in the process to validate the granting of certain mining licenses to Kidman Resources, SQM’s partner in the Mount Holland Project.

These mining properties are a requirement for the development of the project, which are yet to be transferred to the joint venture. Although this recommendation by the Warden’s Court is not a final decision on the requested exception, which should be made by the Mining Minister of Western Australia, it could generate uncertainty or delays the project. SQM and Kidman are reviewing the decision made by the Warden’s Court, and will define the next steps.

On September 13, 2018, it was informed that a hearing was held with the Antitrust Court, Tribunal de la Libre Competencia (TDLC)) to discuss the out of court agreement that was released on Friday, September 7, between the Chilean Antitrust Regulator, Fiscalía Nacional Económica (FNE) and Tianqi Lithium Corporation (Tianqi). As part of this process, the TDLC must approve or reject the agreement, not been able to alter the proposal of the parties.

Through the investigation, the FNE pointed out and verified that the intended Tianqi transaction presents several risks to free competition. Accordingly, the FNE has ruled out that this transaction will result in efficiencies. In both cases, SQM agrees with the FNE, although it believes there are additional risks not mentioned by the FNE.

As a publicly traded corporation with shares traded in Chile as well as on the New York Stock Exchange, SQM has demonstrated that it does not discriminate nor favor on shareholders or investors based on their political views, nationality or other. As such, and having an interest in the TDLC resolution, SQM expressed today, as unanimously agreed to by its Board of Directors the inadequacy of the proposed measures and explained that the agreement should be denied.

SQM is in a situation where it will have to receive a direct competitor as a shareholder, which although it is not illegal, presents risks and challenges to free competition. The aforementioned becomes more complex because of SQM’s open stock corporation status and ownership structure, the political rights that Tianqi will hold once the transaction materializes, and the fact that the proposed measures will have an obvious impact on SQM’s corporate activities.

In this sense, the Company does not believe that the proposed measures in the agreement effectively resolve the risks that it intends to mitigate and do not correctly prevent the access to sensitive information, which could damage



SQM and the market. By having a competitor that is also an important shareholder, SQM could be subject to possible investigations and penalties for reasons that are outside of its control.

Finally, SQM believes that the maximum term contemplated of six years is insufficient. The criteria that has been applied to date is that the risk mitigation measures must last until the risk ceases to exist. If Tianqi believes that no risks will exist in the future, it must prove this to the TDLC and request modification and elimination of said measures. It is not appropriate, as the agreement suggests, for SQM to request to maintain of the measures if the risks persist at the end of the term of the agreement.

On October 24, 2018, it was informed that today SQM's Board of Directors requested that CEO of SQM, Mr. Patricio de Solminihac Tampier's resignation become effective on January 7, 2019 instead of December 31, 2018, as was previously announced. This change is to ensure a smooth transition. Consequently, the Board of Directors agreed that the nomination of Mr. Ricardo Ramos as CEO become effective on January 8, 2019.

On October 31, 2018, it was informed that today the conditions outlined below in the Transaction Agreement (the "Agreement") with Minera Exar ("Exar" or the "Project"), Lithium Americas (TSX: LAC; NYSE: LAC) and GFL International Co. Ltd., which was announced to the market on August 13, 2018 have been met. Pursuant to the Agreement, (a) SQM Potasio has sold to Ganfeng Lithium Netherlands Co., BV (Ganfeng) its entire shareholding and irrevocable contributions in Exar; (b) Exar has paid SQM Potasio, all outstanding loans it received from this company; and (c) Exar has paid SQM for the services rendered to Exar during the Project's development stage. SQM has received a cash inflow of US$87.5 million, which represents a post-tax income of approximately US$5.5 million. This transaction will be accounted for and recognized in SQM's fourth quarter 2018 financial statements.

SQM also informs that SQM Potasio and Ganfeng have executed a Deferred Payment Agreement, under which a deferred payment of US$50 million will be made to SQM Potasio, subject to Exar reaching cumulative sales of (i) 25,000 tons (measured in lithium carbonate equivalent) of the Exar project's lithium products, (ii) at a price of at least US$10,000 per ton.

On December 3, 2018, it was informed that on November 30, 2018, SQM received official letter 32,131 (Oficio 32.131) from the CMF. In this letter, the CMF determined that in accordance with the distribution of the shares of SQM, “there is no shareholder or group of shareholders under the same controlling shareholder, which can decisively influence the management of SQM”. Accordingly, SQM does not have a controller as long as no shareholder can appoint more than three directors representing its Series A shares in order to obtain a majority of the board seats, or until the CMF determines something different in this respect.

On December 5, 2018, it was informed that the Company learned that Inversiones TLC SpA (Chilean tax ID number: 76.902.021-7), a subsidiary of Tianqi Lithium Corporation had acquired the shares of Inversiones El Boldo Limitada, Inversiones PCS Chile Limitada and Inversiones RAC Chile S.A., totaling 62,556,568 shares, representing 23.77% of the total shares of SQM.

On December 5, 2018, it was informed that today the Company received in its offices the resignation letters from Board members Mark Fracchia and Darryl Stann; these resignations are effective today.

On December 13, 2018, it was informed that the Company was informed today that the Minister for Mines and Petroleum in Western Australia has granted Kidman Resources Limited, SQM's partner in the Mount Holland Project, exemption from the relevant expenditure requirements in relation to mining tenements of Mount Holland project that were subject to exemption objections.

## Auditor's responsibility

Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit in accordance with Chilean generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor's judgment, including the assessment of the risks of material misstatements of the consolidated financial statements; whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for purpose of expressing an opinion on the effectiveness of the entity's internal control. Consequently, we do not express such an opinion.

## 1.4 Description of the nature of operations and main activities

Our products are mainly derived from mineral deposits found in northern Chile. We mine and process caliche ore and brine deposits. The caliche ore in northern Chile contains the only known nitrate and iodine deposits in the world and is the world’s largest commercially exploited source of natural nitrates. The brine deposits of the Salar de Atacama, a salt-encrusted depression in the Atacama Desert in northern Chile, contain high concentrations of lithium and potassium as well as significant concentrations of sulfate and boron.



## Note 1 Identification and Activities of the Company and Subsidiaries (continued)

## 1.4 Description of the nature of operations and main activities, continued

From our caliche ore deposits, we produce a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, we extract brines rich in potassium, lithium, sulfate and boron in order to produce potassium chloride, potassium sulfate, lithium solutions and bischoite (magnesium chloride). We produce lithium carbonate and lithium hydroxide at our plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama. We market all of these products through an established worldwide distribution network.

Our products are sold in over 110 countries through our worldwide distribution network, with the majority of our sales derived from countries outside Chile.

Our products are divided into six categories: specialty plant nutrients; iodine and its derivatives; lithium and its derivatives; potassium chloride and potassium sulfate; industrial chemicals and other commodity fertilizers, described as follows:

Specialty plant nutrition: We produce four main types of specialty plant nutrients: potassium nitrate, sodium nitrate, sodium potassium nitrate and specialty blends. We also sell other specialty fertilizers including third party products. All of these specialty plant nutrients are used in either solid or liquid form mainly on high value crops such as vegetables, fruits and flowers. Our nutrients are widely used in crops that employ modern agricultural techniques such as hydroponics, green housing, fertigation (where fertilizer is dissolved in water prior to irrigation) and foliar application. Specialty plant nutrients have certain advantages over commodity fertilizers, such as rapid and effective absorption (without requiring nitrification), superior water solubility, increased soil pH (which reduces soil acidity) and low chloride content. One of the most important products in this business line is potassium nitrate, which is sold in crystalline or prill form, allowing for multiple application methods. Crystalline potassium nitrate products are ideal for application by fertigation and foliar sprays, and potassium nitrate prills are suitable for soil applications.

The new needs of more sophisticated customers demand that the industry provide integrated solutions rather than individual products. Our products, including customized specialty blends that meet specific needs along with the agronomic service provided, allow to create plant nutrition solutions that add value to crops through higher yields and better quality production. Because our products are derived from natural nitrate compounds or natural potassium brines, they have certain advantages over synthetically produced fertilizers, including the presence of certain beneficial trace elements, which makes them more attractive to customers who prefer products of natural origin. As a result, specialty plant nutrients are sold at a premium price compared to commodity fertilizers.

Iodine: We believe that we are the world’s leading producer of iodine and iodine derivatives, which are used in a wide range of medical, pharmaceutical, agricultural and industrial applications, including x-ray contrast media, polarizing films for LCD and LED, antiseptics, biocides and disinfectants, in the synthesis of pharmaceuticals, electronics, pigments and dye components.



## Note 1 Identification and Activities of the Company and Subsidiaries (continued)

## 1.4 Description of the nature of operations and main activities, continued

Lithium: We are a leading producer of lithium carbonate, which is used in a variety of applications, including electrochemical materials for batteries, frits for the ceramic and enamel industries, heat-resistant glass (ceramic glass), air conditioning chemicals, continuous casting powder for steel extrusion, primary aluminum smelting process, pharmaceuticals and lithium derivatives. We are also a leading supplier of lithium hydroxide, which is primarily used as an input for the lubricating greases industry and for certain cathodes for batteries.

Industrial chemicals: We produce three industrial chemicals: sodium nitrate, potassium nitrate and potassium chloride. Sodium nitrate is used primarily in the production of glass, explosives, and metal treatment. Potassium nitrate is used in the manufacturing of specialty glass, and it is also an important raw material for the production of frits for the ceramics and enamel industries. Solar salts, a combination of potassium nitrate and sodium nitrate, are used as a thermal storage medium in concentrated solar power plants. Potassium chloride is a basic chemical used to produce potassium hydroxide, and it is also used as an additive in oil drilling as well as in food processing, among other uses.

Potassium: We produce potassium chloride and potassium sulfate from brines extracted from the Salar de Atacama. Potassium chloride is a commodity fertilizer used to fertilize a variety of crops including corn, rice, sugar, soybean and wheat. Potassium sulfate is a specialty fertilizer used mainly in crops such as vegetables, fruits and industrial crops.

Other products and services: We also sell other fertilizers and blends, some of which we do not produce. We are the largest company that produces and distributes the three main potassium sources: potassium nitrate, potassium sulfate and potassium chloride. This business line also includes revenue from commodities, services, interests, royalties and dividends.

## 2.4 Accounting pronouncements

## New accounting pronouncements

a) The following standards, interpretations and amendments are mandatory for the first time for annual periods beginning on January 1, 2018:

Standards and Interpretations

IFRS 9 Financial Instruments - Published in July 2014. The IASB published the complete version of IFRS 9, which replaces the guidance in IAS 39. This final version includes requirements regarding the classification and measurement of financial assets and liabilities and a new model for the recognition of expected credit losses that replaces the incurred loss impairment model used today. It also includes the final hedging part of IFRS 9 that was issued in November 2013.

IFRS 15 Revenue from Contracts with Customers – Published in May 2014. This standard establishes principles for reporting useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. The core principle is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It replaces IAS 11 Construction Contracts; IAS 18 Revenue; IFRIC 13 Customer Loyalty Programmes; IFRIC 15 Agreements for the Construction of Real Estate; IFRIC 18 Transfers of Assets from Customers; and SIC-31 Revenue-Barter Transactions Involving Advertising Services.

IFRIC 22 “Foreign Currency Transactions and Advance Consideration”. Published in December 2016. This Interpretation applies to a foreign currency transaction (or part of one) if an entity recognizes a non-financial asset or non-financial liability arising from the payment or receipt of an advance consideration prior to the entity recognizing the related asset, expense or income (or the applicable portion thereof). The interpretation provides a guideline for the transaction date to be used for both single payments/receipts and situations when there are multiple payments/receipts. Its objective is to reduce diversity in practice.

Amendments and improvements

Amendment to IFRS 2 Share-based Payments. Published in June 2016. The amendment clarifies the measurement basis for cash-settled, share-based payments and the accounting for modifications that change an award from cash-settled to equity-settled. It also introduces an exception to the principles in IFRS 2 that will require an award to be treated as if it was wholly equity-settled, where an employer is obliged to withhold an amount for the employee’s tax obligation associated with a share-based payment.

Amendment to IFRS 15 “Revenue from Contracts with Customers”. Published in April 2016. The amendment provides clarifications with regard to identifying performance obligations in contracts with customers, accounting for licensing involving intellectual property and assessing principal versus agent considerations (i.e. recording revenue on a gross basis versus the net amount it retains). New and amended illustrative examples have been added for each of those areas of guidance, as well as additional practical expedients related to transition to the new revenue standard.

Amendment to IAS 28 “Investments in Associates and Joint Ventures” in regard to measuring an associate or joint venture at fair value. Published in December 2016.



## Note 2 Basis of presentation for the consolidated financial statements (continued)

## 2.4 Accounting pronouncements, continued

b) Standards, interpretations and amendments issued that had not become effective for financial statements beginning on January 1, 2018 and which the Company has not adopted early are as follows:

Standards and Interpretations

On January 13, 2016, the IASB published IFRS 16 Levies. IFRS 16 introduces a comprehensive model to identify lease agreements and accounting treatments for both lessees and lessors. When the application of IFRS 16 goes into effect, it will replace the current lease guidelines including IAS 17 Leases and the related interpretations.

IFRS 16 makes a distinction between leases and service contracts based on the fact that an identified asset is controlled by an entity. Under IAS 17, the distinction between operating leases (outside the statement of financial position) and financial leases is removed for the accounting of the lessees, and is replaced by a model where a right-of-use asset and the corresponding liability must be recognized by lessees for all leases, except short-term leases and low-value asset leases.

The right-of-use asset is initially measured at cost and subsequently measured at cost (subject to certain exceptions) less accumulated depreciation and impairment losses, adjusted by any remeasurement of the lease liability. The lease liability is initially measured at the present value of the lease payments that have not been paid as of that date. Subsequently, the lease liability is adjusted for interest and lease payments, as well as lease modifications, among others. In addition, the classification of cash flows will also be affected considering that under IAS 17, operating lease payments are presented as operating cash flows; while under the IFRS 16 model, lease payments will be divided between the portion of principal and interest payments, which will be presented as financing and operating cash flows or financing, respectively.

In contrast to accounting for lessees, IFRS 16 substantially maintains the accounting requirements of IAS 17 for lessors, and continues to require lessees to classify leases as either operating or financial leases.

Additionally, IFRS 16 requires more extensive disclosures.

IFRS 16 is effective for annual periods beginning on or after January 1, 2019. Early application is permitted for entities that apply IFRS 15 on or before the initial application of IFRS 16. Entities can apply IFRS 16 using either a retrospective full application approach or a modified retrospective application approach. If the latter approach is chosen, an entity is not required to restate comparative financial information and the cumulative effect of the initial application of IFRS 16 must be presented as an adjustment to the initial balance of retained earnings (or other equity component, when appropriate).

The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary.</td><td>Undetermined</td></tr></table>

Management believes the adoption of the standards, interpretations and amendments applicable as of Tuesday, January 1, 2019, will have no significant impact on the Company’s financial statements.

During 2018, the Administration has made an initial assessment of the possible impact of the adoption of IFRS 16 as of the effective term of the new standard, which was determined through the evaluation of lease contracts, assets that, according to their nature and lease terms must be recorded at the date of initial application as right-to-use assets, and this will incur amortization expenses over the term of the contract or the useful life of the asset, whichever is shorter. Based on this evaluation, the Company concludes that the effects of the adoption of IFRS 16 will not significantly affect its Consolidated Financial Statements.

Of the lease contracts signed under IFRS 16, the following right-of-use assets, among others, were identified: trucks, cranes, excavators, structures (buildings, warehouses, shops, land), where SQM has the power (control) to direct their activities and to use them for the contract term, without the supplier changing the operating instructions.

To estimate the initial measurement, the Company built a debt curve based on public debt instruments held by the company at the valuation date. The rates used to deduct the right-of-use asset and the lease liability were estimated based on currency (USD, UF and CLP) and contract terms.



## Note 2 Basis of presentation for the consolidated financial statements (continued)

## 2.4 Accounting pronouncements, continued

The initial application method of the aforementioned standard chosen by the Company is the full application of a modified approach of retrospective application version B, where the right to use is equated to the aforementioned liability, with no equity adjustment.

The values corresponding to right-to-use assets and lease liabilities in contracts qualified under IFRS 16 amount to ThUS$25,033.

For the adoption of IFRS 15 - Revenue from Contracts with Customers, the Company undertook a detailed assessment of its performance obligations underlying revenue recognition, such as the performance obligation to transport products to customers, in line with the terms and conditions previously established in contracts and there is no significant impact - the performance obligation has been satisfied. With regard to products invoiced with a deferred shipment date, the transfer of control has been assessed over and above the transfer of risks and benefits established in the previous standard and a prepayment is estimated in revenue recognition, without a significant impact. Other considerations were also assessed, such as rebates, discounts, guarantees, financing components and product personalization. Based on this analysis, the Company has concluded that these last items will not generate an impact nor are significant changes expected in the recording of revenue as a result of applying this new standard, except for the impact on disclosures. The Company has established the procedures and controls for beginning to apply IFRS 15 as of January 1, 2018. It recognizes the cumulative effect of applying IFRS 15 as an adjustment to the opening balance of equity as of that date, without being necessary to make adjustments to the comparative information for periods.

## (a) Subsidiaries

These are all those entities where Sociedad Química y Minera de Chile S.A. has control over directing their financial and operational policies. This is generally accompanied by a share of more than half of the voting rights. Subsidiaries apply the same accounting policies of their Parent.

To account for the acquisition, the Company uses the acquisition method. Under this method the acquisition cost is the fair value of assets delivered, equity securities issued, and liabilities incurred or assumed at the date of exchange. Identifiable assets acquired, and liabilities and contingencies assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquiree. For more information, please see Note 8.1.

## Note 2 Basis of presentation for the consolidated financial statements (continued)

## 2.5 Basis of consolidation, continued

Subsidiaries are consolidated using the line-by-line method, adding the items that represent assets, liabilities, revenues, and expenses of similar content, and eliminating those related to intragroup transactions.

Profit or loss of subsidiaries acquired or divested during the year are included in profit or loss accounts consolidated from the date control is transferred to the Group, or up to the date control is lost, as applicable.

Non-controlling interest represents the equity of a subsidiary not directly or indirectly attributable to the Parent.



## Note 3 Significant accounting policies

## 3.1 Classification of balances as current and non-current

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

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

## 3.2 Functional and presentation currency

The Company’s consolidated financial statements are presented in United States dollars (“U.S. dollars”), which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates.

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

The consolidated financial statements are presented in thousands of United States dollars without decimals.

## 3.3 Foreign currency translation

## (a) Group entities:

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

- Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date.

- Revenues and expenses of each profit or loss account are converted at monthly average exchange rates.

- All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves.

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



## Note 3 Significant accounting policies (continued)

## 3.3 Foreign currency translation, continued

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

<table><tr><td></td><td>12/31/2018 US\(</td><td>12/31/2017 US\)</td></tr><tr><td>Brazilian real</td><td>3.87</td><td>3.02</td></tr><tr><td>New Peruvian sol</td><td>3.37</td><td>3.08</td></tr><tr><td>Argentine peso</td><td>37.74</td><td>18.40</td></tr><tr><td>Japanese yen</td><td>110.38</td><td>113.00</td></tr><tr><td>Euro</td><td>0.87</td><td>0.83</td></tr><tr><td>Mexican peso</td><td>19.68</td><td>19.65</td></tr><tr><td>Australian dollar</td><td>1.42</td><td>1.28</td></tr><tr><td>Pound Sterling</td><td>0.79</td><td>0.74</td></tr><tr><td>South African rand</td><td>14.35</td><td>12.35</td></tr><tr><td>Ecuadorian dollar</td><td>1.00</td><td>1.00</td></tr><tr><td>Chilean peso</td><td>694.77</td><td>614.75</td></tr><tr><td>Chinese yuan</td><td>6.88</td><td>6.51</td></tr><tr><td>Indian rupee</td><td>69.93</td><td>63.84</td></tr><tr><td>Thai baht</td><td>32.53</td><td>32.85</td></tr><tr><td>Turkish lira</td><td>5.27</td><td>3.79</td></tr><tr><td>UF (*)</td><td>39.68</td><td>43.59</td></tr></table>

(*) The Unidad de Fomento (UF) is an indexed monetary unit used in Chile, calculated based on the variation in the Consumer Price Index (CPI). It is represented as dollars to UF.

## (b) Transactions and balances

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

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



## Note 3 Significant accounting policies (continued)

## 3.4 Subsidiaries

SQM S.A. uses the level of control it has in subsidiaries as a basis to determine their share in the consolidated financial statements. This control consists of the Company’s ability to exercise power in the subsidiary, exposure, or right, to variable performance from its share in the investee and the ability to use its power on the investee to have an influence on the amount of the investor’s performance.

The Company prepares the consolidated financial statements using consistent accounting policies for the entire Group. The consolidation of a subsidiary commences when the Company has control over the subsidiary and stops when control ceases.

## 3.5 Consolidated statement of cash flows

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

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

The statement of cash flows includes movements in cash performed during the year, determined using the direct method.

## 3.6 Financial assets

Corporate management (“Management”) determines the classification of its financial assets at the time of initial recognition, on the basis of the business model for the management of financial assets and the characteristics of contractual cash flows from the financial assets. In accordance with IFRS 9, financial assets are initially measured at fair value plus, in the case of a financial asset classified at amortized cost, the incurred transaction costs that are directly attributable to the acquisition of the financial asset.

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

As of January 1, 2018, the Company classifies its financial assets in the following categories: at fair value (be it through other comprehensive income or through profit or loss), and at amortized cost. The classification depends on the entity’s business model for managing financial assets and the contractual terms for cash flows.



## Note 3 Significant accounting policies (continued)

## 3.7 Financial liabilities

Management determines the classification of its financial liabilities at the time of initial recognition. As established in IFRS 9, financial liabilities at the time of initial recognition are measured at fair value, less transaction costs that may have been incurred and are directly attributable to the issue of the financial liability Subsequently, they are measured according to their classification, which can be financial liabilities at fair value with changes in profit or financial liabilities at amortized cost.

## 3.8 Financial instruments at fair value through profit or loss

Financial liabilities are classified as at fair value through profit and loss when they are held for trading or designated as such upon initial recognition. Gains and losses from liabilities held for trading are recognized in profit and loss. This category includes derivative instruments not designated for hedge accounting.

## 3.9 Financial instrument offsetting

The Company offsets an asset and liability if and only if it presently has a legally enforceable right of setting off the amounts recognized and has the intent of settling for the net amount of realizing the asset and settling the liability simultaneously.

## 3.10 Reclassification of financial instruments

At such time when the Company changes its business model for managing financial assets, it will reclassify those financial assets affected by the new business model.

Financial liabilities could not be reclassified.

## 3.11 Derivative and hedging financial instruments

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

a) Fair value hedge of assets and liabilities recognized (fair value hedges);

b) Hedging of a single risk associated with an asset or liability recognized or a highly probable forecast transaction (cash flow hedge).



## Note 3 Significant accounting policies (continued)

## 3.11 Derivative and hedging financial instruments, continued

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

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

The fair value of derivative instruments used for hedging purposes is shown in Note 14.3 (hedging assets and liabilities). Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the entry is less than 12 months.

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

## a) Fair value hedge

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

## b) Cash flow hedges

Amounts taken to equity are transferred to profit or loss when the hedged transaction affects profit or loss, as when the hedged interest income or expense is recognized when a projected sale occurs. When the hedged entry is the cost of a non-financial asset or liability, amounts taken to other reserves are transferred to the initial carrying value of the non-financial asset or liability.

If the expected firm transaction or commitment is no longer expected to occur, the amounts previously recognized in equity are transferred to profit or loss. If a hedge instrument expires, is sold, finished, or exercised without any replacement, or if a rollover is performed or if its designation as hedging is revoked, the amounts previously recognized in other reserves are maintained in equity until the expected firm transaction or commitment occurs.



## Note 3 Significant accounting policies (continued)

## 3.12 Available for sale financial assets

Available for sale financial assets are non-derivative financial assets, which have been designated as available for sale and are not classified in any of the previous categories of financial instruments. Available for sale financial instruments are initially recognized at fair value plus any directly attributable transaction costs.

Subsequent to initial recognition, they are recognized at fair value and changes other than impairment losses are recognized in other comprehensive income and presented in equity in the fair value reserve. If an investment is derecognized, the accumulated gain or loss is reclassified to profit or loss.

## 3.13 Derecognition of financial instruments

In accordance with IFRS 9, the Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained.

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

## 3.14 Derivative financial instruments

The Company maintains derivative financial instruments to hedge its exposure to foreign currencies. Derivative financial instruments are recognized initially at fair value; attributable to the Company are recognized when incurred. Subsequent to initial recognition, any changes in the fair value of such derivatives are recognized in profit or loss as part of gains and losses.

The Company permanently assesses the existence of embedded derivatives, both in its contracts and financial instruments, As of December 31, 2018, and December 31, 2017, there were no embedded derivatives.



## Note 3 Significant accounting policies (continued)

## 3.15 Fair value initial measurements

From the initial recognition, the Company measures its assets and liabilities at fair value plus or minus transaction costs incurred that are directly attributable to the acquisition of a financial asset or issuance of a financial liability

## 3.16 Deferred acquisition costs from insurance contracts

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

## 3.17 Classification Leases

## (a) Lease - Finance lease

Leases are classified as finance leases when the Company substantially owns all the risks and rewards inherent in the ownership of the asset. Finance leases are capitalized at the commencement of the lease term at the lower of the fair value of the leased asset and the present value of the minimum lease payments.

Each finance lease payment is apportioned between the liability and the finance charges so as to obtain the constant rate of interest on the remaining balance of the liability. The respective lease obligations, net of finance charges, are included in other non-current liabilities. The interest part of the finance cost is charged to the consolidated financial statements for the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability for each year.

## (b) Lease - Operating lease

Leases where the lessor retains a significant part of the risks and benefits derived from the property are classified as operating leases. Operating lease payments (net of any incentive received by the lessor) should be recognized as an expense in the income statement or capitalized (as appropriate) over the lease term on a straight-line basis.

## 3.18 Trade and other receivables

The Company’s trade receivables are maintained to obtain contractual cash flows (charge and collect) and do not contain a significant financing component, being recognized at the transaction price defined in IFRS 15.

In turn, the Company applies the simplified approach described in IFRS 9 for expected credit losses from the loans to customers portfolio, as these are short-term financial instruments shorter than 12 months, with no significant financing component and they continue until expiration. This approach enables the use of the estimate of expected credit loss throughout the life of the instrument.



## Note 3 Significant accounting policies (continued)

## 3.18 Trade and other receivables, continued

Receivables with a low probability of recovery are fully provisioned, are to measure the expected credit losses of the rest of the portfolio, it is segmented by grouping the trade receivables based on the characteristics of shared credit risk and late payment. The expected loss rates are obtained from the default rates over the last seven years. To covert historic loss in projected loss, the Company uses the behavior of the implicit default probability indicator in the prices of financial derivatives that cover the risk of non-payment of sovereign bonds in countries where the Company generates income from product sales.

The application of IFRS 9 had an impact as of January 1, 2018, due to the application of the new impairment model described in the Company’s Consolidated Financial Statements, resulting in an increased impairment of ThUS$2,301, which was carried over to equity under IAS 8. (For more information, see Note 14.2)

## 3.19 Inventory measurement

The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage.

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

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

1. Provision associated with the lower value of stock, which is directly identified with the product that generates it and involves three types: provision of lower realizable value, which corresponds to the difference between the inventory cost of intermediary or finished products, and the sale price minus the necessary costs to bring them to the same conditions and location as the product with which they are compared; provision for future uncertain use that corresponds to the value of those products in process that are likely not going to be used in sales based on the company’s long-term plans; reprocessing costs of products that are unfeasible for sale due to current specifications.

2. Provision associated with physical differences in inventory: a provision is made for differences that exceed the tolerance considered in the respective inventory process (production units in Chile and the port of Tocopilla carry out at least two inventories a year, the business subsidiaries depend on the last zero ground obtained, but in general it is at least once a year), these differences are recognized immediately.



## Note 3 Significant accounting policies (continued)

## 3.19 Inventory measurement, continued

3. Potential errors in the determination of stock: The company has an algorithm that is reviewed at least once a year and corresponds to diverse percentages assigned to each inventory based on the product, location, complexity involved in the associated measurement, rotation and control mechanisms.

4. Provisions undertaken by business subsidiaries: these are historical percentages that are adjusted as zero ground is attained based on normal inventory management.

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

## 3.20 Investments in associates and joint ventures

Interests in companies over which joint control is exercised (joint venture) or where an entity has a significant influence (associates) are recognized using the equity method of accounting. Significant influence is presumed to exist when interest greater than 20% is held in the capital of an investee.

Under this method, the investment is recognized in the statement of financial position at cost plus changes, subsequent to the acquisition, and considering the proportional share in the equity of the associate. For such purposes, the interest percentage in the ownership of the associate is used. The associated goodwill acquired is included in the carrying amount of the investee and is not amortized. The debit or credit to profit or loss reflects the proportional share in the profit or loss of the associate.

Unrealized gains for transactions with affiliates or associates are eliminated according to the Company’s interest percentage in such entities. Unrealized losses are also eliminated, except if the transaction provides evidence of impairment loss of the transferred asset.

Changes in the equity of associates are recognized on a proportional basis with a charge or credit to “Other reserves” and classified according to their origin.

Reporting dates of the associate, the Company and related policies are similar for equivalent transactions and events under similar circumstances.

In the event that the significant influence is lost or the investment is sold or is held as available for sale, the equity method is discontinued, suspending the recognition of the proportional share of profit or loss.

If the resulting amount according to the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless a commitment exists by the Company to reinstate the Company’s equity position, in which case the related provision for risks and expenses is recorded.

Dividends received by these companies are recorded by reducing the equity value, and the proportional share of profit or loss recognized according to the equity share are included in the consolidated profit or loss accounts in the caption “Equity share of profit (loss) of associates and joint ventures that are accounted for using the equity method of accounting”.



## Note 3 Significant accounting policies (continued)

## 3.21 Transactions with non-controlling interests

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

## 3.22 Related party transactions

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

## 3.23 Property, plant and equipment

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

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

1. Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company.

2. The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the obligation. Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in Property, plant and equipment and amortized in line with the amortization criteria for the associated assets.

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

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

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

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

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



## Note 3 Significant accounting policies (continued)

## 3.24 Depreciation of property, plant and equipment, continued

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

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

## 3.25 Goodwill

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

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



## Note 3 Significant accounting policies (continued)

## 3.26 Intangible assets other than goodwill

Intangible assets other than goodwill mainly relate to water rights, emission rights, commercial brands, costs for rights of way for electricity lines, license costs and the development of computer software and mining property and concession rights, client portfolio and commercial agent.

## (a) Water rights

Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. Given that these assets represent legal rights granted in perpetuity to the Company, they are not amortized, but are subject to annual impairment tests.

## (b) Rights of way for electric lines

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

## (c) Computer software

Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives.

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

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

## (d) Mining property and concession rights

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

## (e) Client portfolio

The period for exploiting these portfolios is unlimited so they are considered assets with an indefinite useful life and are therefore not subject to amortization. However, they are subjected to an annual impairment test and the corresponding amounts are recorded in the profit or loss.



## Note 3 Significant accounting policies (continued)

## 3.26 Intangible assets other than goodwill continued

## (f) Commercial agent

The rights obtained through the acquisition of the commercial agent of Sociedad Agrocom Ltda. corresponded to the fair value of that company’s line of business. The period for exploiting these rights is unlimited so they are considered assets with an indefinite useful life and are therefore not subject to amortization. However the indefinite useful life is subject to review for every reporting period, to see whether indefinite useful life continues to apply.

## 3.27 Research and development expenses

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

## 3.28 Prospecting expenses

The Company holds mining concessions for exploration and exploitation of ore. The Company gives the following treatment to expenses associated with exploration and assessment of these resources:

## • Caliche

Once the rights have been obtained, the Company records the disbursements directly associated with the exploration and assessment of the deposit as an at cost asset. These disbursements include the following items:

- Disbursements for geological surveys, drilling, borehole extraction and sampling, activities related to the technical assessment and commercial viability of the extraction, and in general, any disbursement directly related to specific projects where the objective is to find ore resources.

If the technical studies determine that the ore grade is not economically viable, the asset is directly charged to profit and loss. If determined otherwise, the asset described above is associated with the extractable ore tonnage which is amortized as it is used. These assets are presented in the other non-current assets category, reclassifying the portion related to the area to by extracted that year as stock.

• Expenses related to metal exploration are charged to profit or loss in the period in which they are registered.

- Salar de Atacama exploration expenses are presented in non-current assets in the property, plant and equipment category and correspond mainly to wells that can also be used in the extraction of the deposit and/or monitoring. These are amortized over 10 years.

- Mt Holland exploration expenses primarily consider exploration boreholes and complementary studies for the lithium ore study of the area. These expenses will begin to be amortized in the development stage.



## Note 3 Significant accounting policies (continued)

## 3.29 Impairment of non-financial assets

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

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

When the carrying value of an asset exceeds its recoverable amount, the asset is considered an impaired asset and is reduced to its net recoverable amount.

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

To determine the fair value less costs to sell, an appropriate valuation model is used.

Impairment losses from continuing operations are recognized with a debit to profit or loss in the categories of expenses associated with the impaired asset function, except for properties reevaluated previously where the revaluation was taken to equity.

For assets other than acquired goodwill, an annual evaluation is carried out to determine whether any previously recognized impairment losses have already decreased or ceased to exist. If this should be the case, the recoverable amount is estimated. A previously recognized impairment loss is only reversed if there have been changes in the estimates used to determine the asset’s recoverable amount since the last time an impairment loss was recognized. If this is the case, the carrying value of the asset is increased to its recoverable amount. This increased amount cannot exceed the carrying value that would have been determined, net of depreciation, if an asset impairment loss had not been recognized in prior years. This reversal is recognized with a credit to profit or loss.

## 3.30 Minimum dividend

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

## 3.31 Earnings per share

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

The Company has not conducted any type of operation of potential dilutive effect that would entail the disclosure of diluted earnings per share.



## Note 3 Significant accounting policies (continued)

## 3.32 Trade and other payables

Trade and other payables are measured at fair value plus all costs associated with the transaction. Subsequently, these are carried out at amortized cost using the effective interest rate method.

## 3.33 Interest-bearing borrowings

At initial recognition, interest-bearing borrowings are measured at fair value net of transaction costs incurred. Subsequently, they are measured at amortized cost using the effective interest rate method. Amortized cost is calculated considering any premium or discount from the acquisition and includes costs of transactions which are an integral part of the effective interest rate.

These are recorded as non-current when their expiration period exceeds twelve months and as current when the term is lower than such term. Interest expense is calculated in the year in which it is accrued following a financial criterion.

## 3.34 Other provisions

Provisions are recognized when:

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

- It is more likely than not that certain resources must be used, including benefits, to settle the obligation.

- A reliable estimate can be made of the amount of the obligation.

In the event that the provision or a portion of it is reimbursed, the reimbursement is recognized as a separate asset solely if there is certainty of income.

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

Should the effect of the value of money over time be significant, provisions are discounted using a discount rate before tax that reflects the liability’s specific risks. When a discount rate is used, the increase in the provision over time is recognized as a finance cost

The Company’s policy is to maintain provisions to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from current litigation, compensations or obligations, pending expenses for which the amount has not yet been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time the responsibility or the obligation that determines the compensation or payment is generated.



## Note 3 Significant accounting policies (continued)

## 3.35 Obligations related to employee termination benefits and pension commitments

Obligations towards the Company’s employees comply with the provisions of the collective bargaining agreements in force, which are formalized through collective employment agreements and individual employment contracts, except for the United States, which is regulated in accordance with employment plans in force up to 2002. (See more details in Note 18.4).

These obligations are valued using actuarial calculations, according to the projected unit credit method which considers such assumptions as the mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees' salaries, as well as the effects on variations in services derived from variations in the inflation rate. The criteria in force contained in the revised IAS 19 are also taken into account.

Actuarial gains and losses that may be generated by variations in defined, pre-established obligations are directly recorded in other comprehensive income.

Actuarial losses and gains have their origin in departures between the estimate and the actual behavior of actuarial assumptions or in the reformulation of established actuarial assumptions.

The discount rate used by the Company for calculating the obligation was 4.642% and 5.114% for the periods ended December 31, 2018 and December 31, 2017, respectively.

The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value using a 3.75% interest rate for 2018 and 4.50% for 2017. The net balance of this obligation is presented under the non-current provisions for employee benefits (refer to Note 18.4).

## 3.36 Compensation plans

Compensation plans implemented through benefits provided in share-based payments settled in cash are recognized in the financial statements at their fair value, in accordance with International Financial Reporting Standards No. 2 "Share-based Payments." Changes in the fair value of options granted are recognized with a charge to payroll on a straight-line basis during the period between the date on which these options are granted and the payment date (see Note 18.6).

## 3.37 Revenue recognition

The Company's revenues are predominantly sales of products, where its main performance obligation is to transfer the products under agreements in which the transfer of control, risks, property benefits, and in general, the fulfillment of the Company's performance obligations, occur at the same time.



## Note 3 Significant accounting policies (continued)

## 3.38 Finance income and finance costs

Finance income is mainly composed of interest income in financial instruments such as term deposits and mutual fund deposits. Interest income is recognized in profit or loss at amortized cost, using the effective interest rate method.

Finance costs are mainly composed of interest on bank borrowing expenses, interest on bonds issued and interest capitalized for borrowing costs for the acquisition, construction or production or qualifying assets.

Borrowing costs and bonds issued are recognized in profit or loss using the effective interest rate method.

For finance costs accrued during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, the effective interest rate related to the project’s specific financing is used. If none exists, the average financing rate of the subsidiary making the investment is utilized.

Borrowing and financing costs that are directly attributable to the acquisition, construction or production of an asset are capitalized as part of that asset’s cost.

## 3.39 Income tax and deferred taxes

Corporate income tax for the year is determined as the sum of current taxes from the different consolidated companies.

Current taxes are based on the application of the various types of taxes attributable to taxable income for the year.

Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized.

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

Tax on companies and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in the statement of income accounts or equity accounts in the consolidated statement of financial position, considering the origin of the gains or losses which have generated them.

At each reporting period, the carrying amount of deferred tax assets has been reviewed and reduced to the extent where there will not be sufficient taxable income to allow the recovery of all or a portion of the deferred tax assets. Likewise, as of the date of the consolidated financial statements, deferred tax assets that are not recognized were evaluated and not recognized as it was more likely than not that future taxable income will allow for recovery of the deferred tax asset.

likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used.

With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more

The deferred income tax related to entries directly recognized in equity is recognized with an effect on equity and not with an effect on profit or loss.

Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority.



## Note 3 Significant accounting policies (continued)

## 3.40 Segment reporting

IFRS 8 requires that companies adopt a “management approach” to disclose information on the operations generated by its operating segments. In general, this is the information that management uses internally for the evaluation of segment performance and making the decision on how to allocate resources for this purpose.

An operating segment is a group of assets and operations responsible for providing products or services subject to risks and performance that are different from those of other business segments. A geographical segment is responsible for providing products or services in a given economic environment subject to risks and performance that are different from those of other segments operating in other economic environments.

For assets and liabilities, the allocation to each segment is not possible given that these are associated with more than one segment, except for depreciation, amortization and impairment of assets, which are directly allocated to the applicable segments, in accordance with the criteria established in the costing process for product inventories.

The following operating segments have been identified by the Company:

- Specialty plant nutrients

- Industrial chemicals

- Iodine and derivatives

- Lithium and derivatives

- Potassium

- Other products and services



## Note 3 Significant accounting policies (continued)

## 3.41 Responsibility for Information and Estimates Made

The Management of Sociedad Química y Minera de Chile S.A. and its subsidiaries is responsible for the information contained in these consolidated financial statements, which expressly indicate that all the principles and criteria included in IFRS, as issued by the International Accounting Standards Board (IASB), have been applied in full.

In preparing the consolidated financial statements of Sociedad Química y Minera de Chile S.A. and its subsidiaries, Management has made judgments and estimates to quantify certain assets, liabilities, revenues, expenses and commitments included therein. Basically, these estimates refer to:

- Estimated useful lives are determined based on current facts and past experience, and take into consideration the anticipated physical life of the asset, the potential for technological obsolescence, and regulations. See Notes 3.22, 15 and 16.

- Impairment losses of certain assets - Assets, including property, plant and equipment, exploration assets, goodwill and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their recoverable amounts. If an impairment assessment is required, the assessment of fair value often requires estimates and assumptions such as discount rates, exchange rates, commodity prices, future capital requirements and future operating performance. Changes in such estimates could impact the recoverable values of these assets. Estimates are reviewed regularly by management. See Notes 15 and 16.

- Assumptions used in calculating the actuarial amount of pension-related and severance indemnity payment benefit commitments. See Note 18.

- Contingencies – The amount recognized as a provision, including legal, contractual, constructive and other exposures or obligations, is the best estimate of the consideration required to settle the related liability, including any related interest charges, taking into account the risks and uncertainties surrounding the obligation. In addition, contingencies will only be resolved when one or more future events occur or fail to occur. Therefore, the assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. The Company assesses its liabilities and contingencies based upon the best information available, relevant tax laws and other appropriate requirements. See Notes 19 and 22.

- Provisions on the basis of technical studies that cover the different variables affecting products in stock (density and moisture, among others), and related allowance.

- Obsolescence to ensure that the carrying value of inventory is not in excess of the net realizable Inventory valuation requires judgment to determine obsolescence and estimates of provisions for value. See Note 12.

Despite the fact that these estimates have been made on the basis of the best information available on the date of preparation of these consolidated financial statements, certain events may occur in the future and oblige their amendment (upwards or downwards) over the next few years, which would be made prospectively, recognizing the effects of the change in estimates in the related future consolidated financial statements.



## Note 3 Significant accounting policies (continued)

## 3.42 Environment

In general, the Company follows the criteria of considering amounts used in environmental protection and improvement as environmental expenses. However, the cost of facilities, machinery and equipment used for the same purpose are considered property, plant and equipment, as the case may be.

## Note 4 Changes in accounting estimates and policies (consistent presentation)

## 4.1 Changes in accounting estimates

In the preparation of the consolidated financial statements of the Company and subsidiaries, the management has made estimates regarding the useful lives of Properties, Plants and Equipment, assumptions used for the actuarial calculation of employee benefits, contingencies and provisions (for more information, see Note 3.45)

## 4.2 Changes in accounting policies

As of December 31, 2018, the Company’s consolidated financial statements present no changes in accounting policies or estimates compared to the prior period (for further details refer to Note 3.40).

As of December 31, 2018, the consolidated financial statements of the Company present changes in the accounting policies with respect to the previous period due to application of IFRS 9 and IFRS 15 from January 1, 2018

The consolidated statements of financial position as of December 31, 2018 and, 2017 and the statements of comprehensive income, changes in equity and cash flows for the periods ended December 31, 2018 and 2017, have been prepared in accordance with the IFRS.

The accounting principles and criteria were applied consistently.



## Note 5 Financial risk management

## 5.1 Financial risk management policy

The Company’s financial risk management policy is focused on safeguarding the stability and sustainability of the Company and its subsidiaries with regard to all such relevant financial uncertainty components.

The Company’s operations are subject to certain financial risk factors that may affect its financial position or results. The most significant risk exposures are market risk, liquidity risk, currency risk, doubtful accounts risk, and interest rate risk, among others.

There could also be additional risks, which are either unknown or known but not currently deemed to be significant, which could also affect the Company’s business operations, its business, financial position, or profit or loss.

The financial risk management structure includes identifying, determining, analyzing, quantifying, measuring and controlling these events. Management and, in particular, Finance Management, is responsible for constantly assessing the financial risk. The Company uses derivatives to hedge a significant portion of those risks.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors

## 5.2.1 Risks Relating to Our Business

We could be subject to numerous risks as a result of legal proceedings and deferred prosecution agreements with U.S. and Chilean governmental authorities in relation to certain payments made by SQM between the tax years 2009 and 2015

Following the investigations, the SII and the Chilean Public Prosecutor brought a number of criminal and administrative proceedings against (i) Patricio Contesse G., the Company’s former CEO whose employment was terminated in May 2015, (ii) Mr. Contesse and the Company’s then-current CEO, Patricio de Solminihac, and CFO (now CEO), Ricardo Ramos, in their capacities as the Company’s tax representatives and (iii) five then-current and former members of the Company’s Board of Directors. All the claims against Messrs. de Solminihac and Ramos were subsequently dismissed. The lawsuits against Mr. Contesse and the Board members are continuing.

On October 14, 2015, two class action complaints then pending against the Company, our former CEO and then-current CEO and CFO, alleging violations of the U.S. securities laws in connection with the subject matter of the investigations described above, were consolidated into a single action in the United States District Court for the Southern District of New York. On November 13, 2015, our former CEO and then-current CEO and CFO were voluntarily dismissed from the case without prejudice. On January 15, 2016, the lead plaintiff filed a consolidated class action complaint exclusively against the Company. On January 10, 2018, the lead plaintiff filed a motion to certify a class consisting of all persons who purchased SQM American Depositary Shares (“ADS”) between June 30, 2010 and March 18, 2015, and such motion remains pending before the court.

During 2015, the ad-hoc committee of the Board of Directors (the “ad-hoc Committee”) established in February 2015 to conduct an internal investigation into the matters that were the subject of the SII and Chilean Public Prosecutor investigation, also conducted an investigation into whether the Company faced possible liability under the Foreign Corrupt Practices Act (“FCPA”). The ad-hoc Committee engaged its own separate counsel, Shearman & Sterling LLP, which presented a report to the Board of Directors on December 15, 2015.

Following the presentation by the ad-hoc Committee of its findings to the Board of Directors, the Company voluntarily shared the findings of the ad-hoc Committee investigation with authorities in Chile and the U.S. (including the U.S. Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”)).

On January 13, 2017, the Company and the DOJ reached agreement on the terms of a Deferred Prosecution Agreement (“DPA”) that would resolve the DOJ’s inquiry, based on alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act. Among other terms, the DPA called for the Company to pay a monetary penalty of US$15,487,500, and engage a compliance monitor for a term of two (2) years. Upon successful completion of the three (3) year term of the DPA, all charges against the Company will be dismissed. On the same date, the SEC agreed to resolve its inquiry through an administrative cease and desist order, arising out of the alleged violations of the same accounting provisions of the FCPA. Among other terms, the SEC order called for the Company to pay an additional monetary penalty of US$15 million.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

On January 26, 2018, the Eighth Lower Criminal Court of Santiago approved a deferred prosecution agreement proposed by the Chilean Public Prosecutor relating to SQM and its subsidiaries, SQM Salar and SQM Nitratos S.A., to suspend an investigation against these entities related to potential corruption issues and responsibility for the lack of supervision and management. Under the deferred prosecution agreement, SQM, SQM Salar and SQM Nitratos S.A., have not admitted responsibility in the matter subject to the investigation but agreed to pay an aggregate amount of (i) Ch$900,000,000 to the Chilean government, and (ii) Ch$1,650,000,000 to various charitable organizations. As of January 26, 2018, these amounts were equivalent to approximately US$1.5 million and US$2.8 million, respectively. In addition, the companies have agreed to provide the Chilean Public Prosecutor with a report on the enhancements to their compliance program, implemented in recent years, with special emphasis on the incorporation of best practices in various jurisdictions. On August 17, 2018, the Eighth Lower Criminal Court of Santiago considered the conditions and decided to terminate the legal process.

In the event that the applicable regulatory authorities believe that the terms of the DPA or the deferred prosecution agreement with the Chilean Public Prosecutor are not complied with, it is possible that such regulatory authorities may reinstate the suspended proceedings against us and may bring further action against us, including in the form of additional inquiries or legal proceedings. Responding to our regulators' inquiries and any future civil, criminal or regulatory inquiries or proceedings diverts our management's attention from day-to-day operations. Additionally, expenses that may arise from responding to such inquiries or proceedings, our review of responsive materials, any related litigation or other associated activities may continue to be significant. Current and former employees, officers and directors may seek indemnification, advancement or reimbursement of expenses from us, including attorneys' fees, with respect to the current inquiry or future proceedings related to this matter. The occurrence of any of the foregoing or adverse determination in litigation or other proceedings or similar actions could materially and adversely affect our business, financial condition, cash flows, results of operations and the prices of our securities.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

We identified a material weakness in our internal controls over payments directed by the office of the former Chief Executive Officer

In the past, our management determined that the Company did not maintain effective control over payments directed by the office of the former CEO. This determination was reported in our annual report for the year ended December 31, 2014 on Form 20-F, filed with the SEC on May 18, 2015.

We believe we have taken the necessary steps to remediate the identified material weakness and enhance our internal controls. However, any failure to maintain effective internal control over financial reporting could (i) result in a material misstatement in our financial reporting or financial statements that would not be prevented or detected, (ii) cause us to fail to meet our reporting obligations under applicable securities laws or (iii) cause investors to lose confidence in our financial reporting or financial statements, the occurrence of any of which could materially and adversely affect our business, financial condition, cash flows, results of operations and the prices of our securities.

Volatility of world lithium, fertilizer and other chemical prices and changes in production capacities could affect our business, financial condition and results of operations.

The prices of our products are determined principally by world prices, which, in some cases, have been subject to substantial volatility in recent years. World lithium, fertilizer and other chemical prices constantly vary depending upon the relationship between supply and demand at any given time. Supply and demand dynamics for our products are tied to a certain extent to global economic cycles, and have been impacted by circumstances related to such cycles. Furthermore, the supply of lithium, certain fertilizers or other chemical products, including certain products that we provide, varies principally depending on the production of the major producers, (including us) and their respective business strategies.

World prices of potassium-based fertilizers (including some of our specialty plant nutrients and potassium chloride) fluctuated as a result of the broader global economic and financial conditions. During the second half of 2013, potassium prices declined as a result of an unexpected announcement made by the Russian company Uralkali (“Uralkali”) that it was terminating its participation in Belarus Potash Corporation (“BPC”). As a result of the termination of Uralkali’s participation in BPC, there was increased price competition in the market. In 2018, the average price for our potassium chloride and potassium sulfate business line was approximately 14% higher than in 2017. Our sales volumes for this business line were approximately 38% lower in 2018 compared to 2017. We cannot assure you that potassium-based fertilizer prices and sales volumes will not decline in the future.

Iodine prices followed an upward trend beginning at the end of 2008 and continuing through 2012, reaching an average price of approximately US$53 per kilogram in 2012, over 40% higher than average prices in 2011. During the following years, supply growth outpaced demand growth, causing a decline in iodine prices. We obtained an average price for iodine of approximately US$24 per kilogram in 2018, approximately 23% more than average prices obtained in 2017. We cannot assure you that iodine prices or sales volumes will not continue to decline in the future.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

In 2018, lithium demand continued to grow creating tight market conditions and increasing prices by 26% compared to 2017, driven mostly by an increase in demand related to battery use. During the second half of 2018, lithium supply increased, and prices slightly decreased in the fourth quarter. We cannot assure you that lithium prices and sales volumes will not decline in the future.

We expect that prices for the products we manufacture will continue to be influenced, among other things, by worldwide supply and demand and the business strategies of major producers. Some of the major producers (including us) have increased or have the ability to increase production. As a result, the prices of our products may be subject to substantial volatility. High volatility or a substantial decline in the prices or sales volumes of one or more of our products could have a material adverse effect on our business, financial condition and results of operations.

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

We sell our products in more than 110 countries around the world. In 2018, approximately 34% of our sales were made in emerging market countries: 8% in Latin America (excluding Chile); 8% in Africa and the Middle East (excluding Israel); 8% in Chile and 11% in Asia and Oceania (excluding Australia, Japan, New Zealand, South Korea and Singapore). We expect to expand our sales in these and other emerging markets in the future. In addition, we may carry out acquisitions or joint ventures in jurisdictions in which we currently do not operate, relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. The results of our operations and our prospects in other countries in which we establish operations will depend, in part, on the general level of political stability and economic activity and policies in those countries. Future developments in the political systems or economies of these countries or the implementation of future governmental policies in those countries, including the imposition of withholding and other taxes, restrictions on the payment of dividends or repatriation of capital, the imposition of import duties or other restrictions, the imposition of new environmental regulations or price controls or changes in relevant laws or regulations, could have a material adverse effect on our business, financial condition and results of operations in those countries.

## Our inventory levels may vary for economic or operational reasons

In general, economic conditions or operational factors can affect our inventory levels. Higher inventories carry a financial risk due to increased need for cash to fund working capital and could imply increased risk of loss of product. At the same time, lower levels of inventory can hinder the distribution network and process, thus impacting sales volumes. There can be no assurance that inventory levels will remain stable. These factors could have a material adverse effect on our business, financial condition and results of operations.

New production of iodine or lithium from current or new competitors in the markets in which we operate could adversely affect prices

In recent years, new and existing competitors have increased the supply of iodine and lithium, which has affected prices for both products. Further production increases could negatively impact prices. There is limited information on the status of new iodine or lithium production capacity expansion projects being developed by current and potential competitors and, as such, we cannot make accurate projections regarding the capacities of possible new entrants into the market and the dates on which they could become operational. If these potential projects are completed in the short term, they could adversely affect market prices and our market share, which, in turn, could have a material adverse effect on our business, financial condition and results of operations.

## We have a capital expenditure program that is subject to significant risks and uncertainties

Our business is capital intensive. Specifically, the exploration and exploitation of reserves, mining and processing costs, the maintenance of machinery and equipment and compliance with applicable laws and regulations require substantial capital expenditures. We must continue to invest capital to maintain or to increase our exploitation levels and the amount of finished products we produce.

In addition, we require environmental permits for our new projects. Obtaining permits in certain cases may cause significant delays in the execution and implementation of new projects and, consequently, may require us to reassess the related risks and economic incentives. We cannot assure you that we will be able to maintain our production levels or generate sufficient cash flow, or that we will have access to sufficient investments, loans or other financing alternatives, to continue our activities at or above present levels, or that we will be able to implement our projects or receive the necessary permits required for them in time. Any or all of these factors may have a material adverse effect on our business, financial condition and results of operations.

High raw materials and energy prices could increase our production costs and cost of sales, and energy may become unavailable at any price

We rely on certain raw materials and various energy sources (diesel, electricity, liquefied natural gas, fuel oil and others) to manufacture our products. Purchases of energy and raw materials we do not produce constitute an important part of our cost of sales. In addition, we may not be able to obtain energy at any price if supplies are curtailed or otherwise become unavailable. To the extent we are unable to pass on increases in the prices of energy and raw materials to our customers or we are unable to obtain energy, our business, financial condition and results of operations could be materially adversely affected.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

Our reserve estimates are internally prepared and not subject to review by external geologists or an external auditing firm and could be subject to significant changes, which may have a material adverse effect on our business, financial condition and results of operations

Our caliche ore mining reserve estimates and our Salar de Atacama brine mining reserve estimates are prepared by our own geologists and hydrogeologists and are not subject to review by external geologists or an external auditing firm. Estimation methods involve numerous uncertainties as to the quantity and quality of the reserves, and reserve estimates could change upwards or downwards. A downward change in the quantity and/or quality of our reserves could affect future volumes and costs of production and therefore have a material adverse effect on our business, financial condition and results of operations.

## Quality standards in markets in which we sell our products could become stricter over time

In the markets in which we do business, customers may impose quality standards on our products and/or governments may enact stricter regulations for the distribution and/or use of our products. As a result, if we cannot meet such new standards or regulations, we may not be able to sell our products. In addition, our cost of production may increase in order to meet any such newly imposed or enacted standards or regulations. Failure to sell our products in one or more markets or to important customers could materially adversely affect our business, financial condition and results of operations.

## Chemical and physical properties of our products could adversely affect their commercialization

Since our products are derived from natural resources, they contain inorganic impurities that may not meet certain customer or government standards. As a result, we may not be able to sell our products if we cannot meet such requirements. In addition, our cost of production may increase in order to meet such standards. Failure to meet such standards could materially adversely affect our business, financial condition and results of operations if we are unable to sell our products in one or more markets or to important customers in such markets.

Our business is subject to many operating and other risks for which we may not be fully covered under our insurance policies

Our facilities and business operations in Chile and abroad are insured against losses, damage or other risks by insurance policies that are standard for the industry and that would reasonably be expected to be sufficient by prudent and experienced persons engaged in businesses similar to ours.

We may be subject to certain events that may not be covered under our insurance policies, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, as a result of major earthquakes and unexpected rains and flooding in Chile, as well as other natural disasters worldwide, conditions in the insurance market have changed and may continue to change in the future, and as a result, we may face higher premiums and reduced coverage, which could have a material adverse effect on our business, financial condition and results of operations.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

## Changes in technology or other developments could result in preferences for substitute products

Our products, particularly iodine, lithium and their derivatives, are preferred raw materials for certain industrial applications, such as rechargeable batteries and liquid-crystal displays (LCDs). Changes in technology, the development of substitute products or other developments could adversely affect demand for these and other products which we produce. In addition, other alternatives to our products may become more economically attractive as global commodity prices shift. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

## We are exposed to labor strikes and labor liabilities that could impact our production levels and costs

Over 93% of our employees are employed in Chile, of which approximately 65% were represented by 22 labor unions as of December 31, 2018. We are exposed to labor strikes and illegal work stoppages that could impact our production levels. If a strike or illegal work stoppage occurs and continues for a sustained period of time, we could be faced with increased costs and even disruption in our product flow that could have a material adverse effect on our business, financial condition and results of operations.

Chilean Law No. 20,123, known as the Subcontracting Law, provides that when a serious workplace accident occurs, the company in charge of the workplace must halt work at the site where the accident took place until authorities from either the National Geology and Mining Service (Servicio Nacional de Geología y Minería or “Sernageomin”), the Labor Board (Dirección del Trabajo or “Labor Board”), or the National Health Service (Servicio Nacional de Salud), inspect the site and prescribe the measures such company must take to minimize the risk of similar accidents taking place in the future. Work may not be resumed until the applicable company has taken the prescribed measures, and the period of time before work may be resumed may last for a number of hours, days, or longer. The effects of this law could have a material adverse effect on our business, financial condition and results of operations.

On September 8, 2016, Chilean Law No. 20,940 was published and modified the Labor Code by introducing, among other things, changes to the formation of trade unions, the election of inter-company union delegates, the presence of women on union boards, anti-union practices and related sanctions, and collective negotiations. Due to these changes to the labor regulations, we may face an increase in our expenses that may have a significant adverse effect on our business, financial condition, and results of operations.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

## Lawsuits and arbitrations could adversely impact us

We are party to a range of lawsuits and arbitrations involving different matters as described in Note 22.1. Although we intend to defend our positions vigorously, our defense of these actions may not be successful and responding to such lawsuits and arbitrations diverts our management’s attention from day-to-day operations. Adverse judgments or settlements in these lawsuits may have a material adverse effect on our business, financial condition and results of operations. In addition, our strategy of being a world leader includes entering into commercial and production alliances, joint ventures and acquisitions to improve our global competitive position. As these operations increase in complexity and are carried out in different jurisdictions, we may be subject to legal proceedings that, if settled against us, could have a material adverse effect on our business, financial condition and results of operations.

## We have operations in multiple jurisdictions with differing regulatory, tax and other regimes

We operate in multiple jurisdictions with complex regulatory environments that are subject to different interpretations by companies and respective governmental authorities. These jurisdictions may have different tax codes, environmental regulations, labor codes and legal framework, which adds complexity to our compliance with these regulations. Any failure to comply with such regulations could have a material adverse effect on our business, financial condition and results of operations.

## Environmental laws and regulations could expose us to higher costs, liabilities, claims and failure to meet current and future production targets

Our operations in Chile are subject to national and local regulations relating to environmental protection. In accordance with such regulations, we are required to conduct environmental impact studies or statements before we conduct any new projects or activities or significant modifications of existing projects that could impact the environment or the health of people in the surrounding areas. We are also required to obtain an environmental license for certain projects and activities. The Environmental Evaluation Service (Servicio de Evaluación Ambiental) evaluates environmental impact studies submitted for its approval. The public, government agencies or local authorities may review and challenge projects that may adversely affect the environment, either before these projects are executed or once they are operating, if they fail to comply with applicable regulations. In order to ensure compliance with environmental regulations, Chilean authorities may impose fines up to approximately US$9 million per infraction, revoke environmental permits or temporarily or permanently close facilities, among other enforcement measures.

Chilean environmental regulations have become increasingly stringent in recent years, both with respect to the approval of new projects and in connection with the implementation and development of projects already approved, and we believe that this trend is likely to continue. Given public interest in environmental enforcement matters, these regulations or their application may also be subject to political considerations that are beyond our control.

We regularly monitor the impact of our operations on the environment and on the health of people in the surrounding areas and have, from time to time, made modifications to our facilities to minimize any adverse impact. Future developments in the creation or implementation of environmental requirements or their interpretation could result in substantially increased capital, operation or compliance costs or otherwise adversely affect our business, financial condition and results of operations.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.1 Risks Relating to Our Business (continued)

The success of our current investments at the Salar de Atacama and Nueva Victoria is dependent on the behavior of the ecosystem variables being monitored over time. If the behavior of these variables in future years does not meet environmental requirements, our operation may be subject to important restrictions by the authorities on the maximum allowable amounts of brine and water extraction.

Our future development depends on our ability to sustain future production levels, which requires additional investments and the submission of the corresponding environmental impact studies or statements. If we fail to obtain approval or required environmental licenses, our ability to maintain production at specified levels will be seriously impaired, thus having a material adverse effect on our business, financial condition and results of operations.

In addition, our worldwide operations are subject to international and other local environmental regulations. Since environmental laws and regulations in the different jurisdictions in which we operate may change, we cannot guarantee that future environmental laws, or changes to existing environmental laws, will not materially adversely impact our business, financial condition and results of operations.

## Our water supply could be affected by geological changes or climate change

Our access to water may be impacted by changes in geology, climate change or other natural factors, such as wells drying up or reductions in the amount of water available in the wells or rivers from which we obtain water, that we cannot control. Any such change may have a material adverse effect on our business, financial condition and results of operations.

## Any loss of key personnel may materially and adversely affect our business

Our success depends in large part on the skills, experience and efforts of our senior management team and other key personnel. The loss of the services of key members of our senior management or employees with critical skills could have a negative effect on our business, financial condition and results of operations. If we are not able to attract or retain highly skilled, talented and qualified senior managers or other key personnel, our ability to fully implement our business objectives may be materially and adversely affected.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.2 Risks Relating to Chile

## As we are a company based in Chile, we are exposed to Chilean political risks

Our business, results of operations, financial condition and prospects could be affected by changes in policies of the Chilean government, other political developments in or affecting Chile, legal changes in the standards or administrative practices of Chilean authorities or the interpretation of such standards and practices, over which we have no control.

Changes in regulations regarding, or any revocation or suspension of our concessions could negatively affect our business

Any changes to regulations to which we are subject or adverse changes to our concession rights, or a revocation or suspension of our concessions, could have a material adverse effect on our business, financial condition and results of operations.

## Changes in mining or port concessions could affect our operating costs.

We conduct our mining operations, including brine extraction, under exploitation and exploration concessions granted in accordance with provisions of the Chilean constitution and related laws and statutes. Our exploitation concessions essentially grant a perpetual right (with the exception of the rights granted to SQM Salar with respect to the Salar de Atacama concessions under the Lease Agreement described above, which expires in 2030) to conduct mining operations in the areas covered by the concessions, provided that we pay annual concession fees. Our exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time and to subsequently request a corresponding exploitation concession.

Our subsidiary SQM Salar holds exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement and the Project Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo's rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030.

Our business is substantially dependent on the exploitation rights under the Lease Agreement and the Project Agreement, since all of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. These agreements expire in 2030 and establish a series of obligations with which SQM Salar must comply. A serious failure to comply with these obligations may jeopardize the exploitation rights under the agreements and the continuity of our operations in the Salar de Atacama. While we believe that we have taken the appropriate precautions to ensure compliance with the obligations and conditions in the agreements, there can be no assurance that we will be able to maintain such compliance, which could jeopardize the continued benefits to us of the agreements and could have a material adverse effect on our business, financial condition and results of operations.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.2 Risks Relating to Chile (continued)

We also operate port facilities at Tocopilla, Chile, for the shipment of products and the delivery of raw materials pursuant to maritime concessions, which have been granted under applicable Chilean laws and are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

Any significant adverse changes to any of these concessions could have a material adverse effect on our business, financial condition and results of operations.

## Changes in water rights laws and other regulations could affect our operating costs

We hold water use rights that are key to our operations. These rights were obtained from the Chilean Water Authority (Dirección General de Aguas) for supply of water from rivers and wells near our production facilities, which we believe are sufficient to meet current operating requirements. However, the Chilean Water Rights Code (Código de Aguas or the “Water Code”) is subject to changes, which could have a material adverse impact on our business, financial condition and results of operations. For example, a series of bills are currently being discussed at the Chilean National Congress that seek to desalinate seawater for use in mining production processes, amend the Mining Code for water use in mining operations, amend the Political Constitution on water and introduce changes to the regulatory framework governing the terms of inspection and sanction of water. As a result, the amount of water that we can actually use under our existing rights may be reduced or the cost of such use could increase. These and potential future changes to the Water Code or other relevant regulations could have a material adverse effect on our business, financial condition and results of operations.

## The Chilean government could levy additional taxes on corporations operating in Chile

In Chile, there is a royalty tax that is applied to mining activities developed in the country.

On September 29, 2014, Law No. 20,780 was published (the “Tax Reform”), introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. As a result of these reforms, open stock corporations like SQM are subject to the partially integrated shareholder tax regime (sistema parcialmente integrado). The corporate tax rate applicable to us increased to 25.5% in 2017 and increased to the maximum rate of 27% in 2018.

Under the partially integrated shareholder taxation regime, shareholders bear the tax on dividends upon payment, but they will only be permitted to credit against such shareholder taxes a portion of the Chilean corporate tax paid by us on our earnings, unless the shareholder is resident in a country with a tax treaty in force with Chile. In that case, 100% of the Chilean corporate tax paid by us may be credited against the final taxes at the shareholder level.

As a result, foreign shareholders resident in a non-treaty jurisdiction will be subject to a higher effective tax rate than residents of treaty jurisdictions. There is a temporary rule in effect from January 1, 2017 through December 31, 2019 that treaty jurisdictions for this purpose will include jurisdictions with tax treaties signed with Chile prior to January 1, 2017, whether or not such treaties are in force. This is currently the status of the treaty signed between Chile and United States. After December 31, 2019, if no treaty is in effect, shareholders in those jurisdictions will be subject to a higher effective tax rate.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.2 Risks Relating to Chile (continued)

The Tax Reform tax increase prompted a US$52.3 million increase in our deferred tax liabilities as of December 31, 2014. In accordance with the instructions issued by the CMF, the effects generated by the change in the income tax rate were accounted for as retained earnings.

In addition, the Tax Reform may have other material adverse effects on our business, financial condition and results of operations. Likewise, we cannot assure you that the manner in which the Royalty Law (as defined below) or the corporate tax rate are interpreted and applied will not change in the future. The Chilean government may decide to levy additional taxes on mining companies or other corporations in Chile. Such changes could have a material adverse effect on our business, financial condition and results of operations.

Ratification of the International Labor Organization’s Convention 169 concerning indigenous and tribal peoples might affect our development plans

Chile, a member of the International Labor Organization (“ILO”), has ratified the ILO’s Convention 169 (the “Indigenous Rights Convention”) concerning indigenous and tribal people. The Indigenous Rights Convention established several rights for indigenous people and communities. Among other rights, the Indigenous Rights Convention states that (i) indigenous groups should be notified and consulted prior to the development of any project on land deemed indigenous, although veto rights are not mentioned, and (ii) indigenous groups have, to the extent possible, a stake in benefits resulting from the exploitation of natural resources in indigenous land. The extent of these benefits has not been defined by the Chilean government. The Chilean government has addressed item (i) above through Supreme Decree No. 66, issued by the Social Development Ministry. This decree requires government entities to consult indigenous groups that may be directly affected by the adoption of legislative or administrative measures, and it also defines criteria for the projects or activities that must be reviewed through the environmental evaluation system that also require such consultation. To the extent that the new rights outlined in the Indigenous Rights Convention become laws or regulations in Chile, judicial interpretations of the convention of those laws or regulations could affect the development of our investment projects in lands that have been defined as indigenous, which could have a material adverse effect on our business, financial condition and results of operations.

## Chile is located in a seismically active region

Chile is prone to earthquakes because it is located along major fault lines. The most recent major earthquakes in Chile, which occurred in April 2017 in the Valparaíso region and in December 2016 in Chiloe Island, had a magnitude of 6.9 and 7.6, respectively, on the Richter scale. There were also earthquakes in 2015, 2014 and 2010 that caused substantial damage to some areas of the country. Chile has also experienced volcanic activity. A major earthquake or a volcanic eruption could have significant negative consequences for our operations and for the general infrastructure, such as roads, rail, and access to goods, in Chile. Although we maintain industry standard insurance policies that include earthquake coverage, we cannot assure you that a future seismic or volcanic event will not have a material adverse effect on our business, financial condition and results of operations.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.3 Risks Relating to our Shares and to our ADSs

The price of our ADSs and the U.S. dollar value of any dividends will be affected by fluctuations in the U.S. dollar/Chilean peso exchange rate

Chilean trading in the shares underlying our ADSs is conducted in Chilean pesos. The depositary will receive cash distributions that we make with respect to the shares in Chilean pesos. The depositary will convert such Chilean pesos to U.S. dollars at the then prevailing exchange rate to make dividend and other distribution payments in respect of ADSs. If the value of the Chilean peso falls relative to the U.S. dollar, the value of the ADSs and any distributions to be received from the depositary will decrease.

## Developments in other emerging markets could materially affect the value of our ADSs and our shares

The Chilean financial and securities markets are, to varying degrees, influenced by economic and market conditions in other emerging market countries or regions of the world. Although economic conditions are different in each country or region, investor reaction to developments in one country or region can have significant effects on the securities of issuers in other countries and regions, including Chile and Latin America. Events in other parts of the world may have a material effect on Chilean financial and securities markets and on the value of our ADSs and our shares.

The volatility and low liquidity of the Chilean securities markets could affect the ability of our shareholders to sell our ADSs

The Chilean securities markets are substantially smaller, less liquid and more volatile than the major securities markets in the United States. The volatility and low liquidity of the Chilean markets could increase the price volatility of our ADSs and may impair the ability of a holder to sell our ADSs into the Chilean market in the amount and at the price and time the holder wishes to do so.

## Our share or ADS price may react negatively to future acquisitions and investments

As world leaders in our core businesses, part of our strategy is to look for opportunities that will allow us to consolidate and strengthen our competitive position in jurisdictions in which we currently do not operate. Pursuant to this strategy, we may carry out acquisitions or joint ventures relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. Depending on our capital structure at the time of such acquisitions or joint ventures, we may need to raise significant debt and/or equity which will affect our financial condition and future cash flows. Any change in our financial condition could affect our results of operations, negatively impacting our share or ADS price.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.3 Risks Relating to our Shares and to our ADSs (continued)

## ADS holders may be unable to enforce rights under U.S. securities laws

Because we are a Chilean company subject to Chilean law, the rights of our shareholders may differ from the rights of shareholders in companies incorporated in the United States, and ADS holders may not be able to enforce or may have difficulty enforcing rights currently in effect under U.S. federal or state securities laws.

Our Company is an open stock corporation incorporated under the laws of the Republic of Chile. Most of our directors and officers reside outside the United States, principally in Chile. All or a substantial portion of the assets of these persons are located outside the United States. As a result, if any of our shareholders, including holders of our ADSs, were to bring a lawsuit against our officers or directors in the United States, it may be difficult for them to effect service of legal process within the United States upon these persons. Likewise, it may be difficult for them to enforce judgments obtained in United States courts based upon the civil liability provisions of the federal securities laws in the United States against them in the United States.

In addition, there is no treaty between the United States and Chile providing for the reciprocal enforcement of foreign judgments. However, Chilean courts have enforced judgments rendered in the United States, provided that the Chilean court finds that the United States court respected basic principles of due process and public policy. Nevertheless, there is doubt as to whether an action could be brought successfully in Chile in the first instance on the basis of liability based solely upon the civil liability provisions of the United States federal securities laws.

As preemptive rights may be unavailable for our ADS holders, they have the risk of their holdings being diluted if we issue new stock

Chilean laws require companies to offer their shareholders preemptive rights whenever issuing new shares of capital stock so shareholders can maintain their existing ownership percentage in a company. If we increase our capital by issuing new shares, a holder may subscribe for up to the number of shares that would prevent dilution of the holder’s ownership interest.

If we issue preemptive rights, United States holders of ADSs would not be able to exercise their rights unless a registration statement under the Securities Act were effective with respect to such rights and the shares issuable upon exercise of such rights or an exemption from registration were available. We cannot assure holders of ADSs that we will file a registration statement or that an exemption from registration will be available. We may, in our absolute discretion, decide not to prepare and file such a registration statement. If our holders were unable to exercise their preemptive rights because we did not file a registration statement, the depositary bank would attempt to sell their rights and distribute the net proceeds from the sale to them, after deducting the depositary’s fees and expenses. If the depositary could not sell the rights, they would expire and holders of ADSs would not realize any value from them. In either case, ADS holders’ equity interests in us would be diluted in proportion to the increase in our capital stock.



## Note 5 Financial Risk Management (continued)

## 5.2 Risk Factors (continued)

## 5.2.3 Risks Relating to our Shares and to our ADSs (continued)

If we were classified as a Passive Foreign Investment Company by the U.S. Internal Revenue Service, there could be adverse consequences for U.S. investors

We believe that we were not classified as a Passive Foreign Investment Company (“PFIC”) for 2018. Characterization as a PFIC could result in adverse U.S. tax consequences to you if you are a U.S. investor in our shares or ADSs. For example, if we (or any of our subsidiaries) are a PFIC, our U.S. investors may become subject to increased tax liabilities under U.S. tax laws and regulations and will become subject to burdensome reporting requirements. The determination of whether or not we (or any of our subsidiaries or portfolio companies) are a PFIC is made on an annual basis and will depend on the composition of our (or their) income and assets from time to time.

## Changes in Chilean tax regulations could have adverse consequences for U.S. investors

Currently cash dividends paid by us to foreign shareholders are subject to a 35% Chilean withholding tax. When the Company pays a corporate income tax on the income from which the dividend is paid, known as a “First Category Tax”, a credit for the full amount of the First Category Tax effectively reduces the rate of Withholding Tax. Changes in Chilean tax regulations could have adverse consequences for U.S. investors.



## Note 5 Financial risk management, continued

## 5.2.4 Credit risk

A global economic downturn - and its potentially negative effects on the financial situation of our customers - could extend the payment terms of the Company's receivables by increasing its exposure to credit risk. Although measures are taken to minimize the risk, this global economic situation could mean losses with adverse material effects on the business, financial position or profit and loss of the Company's operations.

To mitigate these risks, the Company maintains active control of collection and uses measures such as the use of credit insurance, letters of credit and prepayments for a portion of receivables.

Financial investments correspond to time deposits whose maturity date is greater than 90 days and less than 360 days from the date of investment, so they are not exposed to excessive market risks.

The credit quality of financial assets that are not past due or impaired can be evaluated by reference to external credit ratings (if available) or historical information on counterparty late payment rates:

## 5.2.5 Currency risk

The functional currency of the Company is the US Dollar, due to its influence on the determination of price levels, its relation to the cost of sales and considering that a significant part of the Company’s business is conducted in this currency. However, the global nature of the Company’s business generates an exposure to exchange rate variations of several currencies with the US Dollar. Therefore, the Company maintains hedge contracts to mitigate the exposure generated by its main mismatches (net between assets and liabilities) in currencies other than the US dollar against the exchange rate variation, updating these contracts periodically depending on the amount of mismatching to be covered in these currencies. Occasionally, subject to the approval of the Company’s Board of Directors (the “Board”), the Company ensures short-term cash flows from certain specific line items in currencies other than the US Dollar.

A significant portion of the Company’s costs, especially salary payments, is associated with the Chilean peso (the “Peso”). Therefore, an increase or decrease in its exchange rate with the US Dollar would affect the Company’s profit and loss. By the fourth quarter, approximately US$400 million accumulated in expenses are associated with the Peso. A significant part of the effect of these liabilities on the Statement of Financial Position is covered by derivative instrument operations that cover the balance sheet mismatch.

As of December 31, 2018, the Company held derivative instruments classified as hedges of foreign exchange risks associated with all of the bond liabilities denominated in UF, for a fair value of US$3.9 million against the Company. As of September 30, 2018, this value amounted to US$21.3 million in favor of the Company and as of December 31, 2017, it totaled US$5 million against the Company.

As of December 31, 2018, the exchange rate value for equivalent Pesos to US Dollars was Ch$694.77 per US Dollar, as of September 30, 2018, it was Ch$660.42 per Dollar and as of December 31, 2017, it was Ch$614.75 per US Dollar.



## Note 5 Financial risk management, continued

## 5.2.6 Interest rate risk

Interest rate fluctuations, primarily due to the uncertain future behavior of markets, may have a material impact on the financial results of the Company.

The Company maintains current and non-current financial debt valued at the LIBOR rate plus spread.

As of Monday, December 31, 2018, the Company has around 5% of its financial liabilities linked to variations in the LIBOR rate and therefore any significant increases in that rate would impact its financial position. A change of 100 base points over that rate could generate variations in finance costs of around US$0.06 million.

Additionally, as of December 31, 2018, the Company does not maintain maturities of less than 12 months on all capital of the financial debt, thereby reducing exposure to variations in interest rates.

## 5.2.7 Liquidity risk

Liquidity risk relates to the funds needed to comply with payment obligations. The Company’s objective is to maintain financial flexibility through a comfortable balance between fund requirements and cash flows from regular business operations, bank borrowings, bonds, short term investments, and marketable securities, among others.

The Company has an important capital expense program which is subject to change over time.

On the other hand, world financial markets go through periods of contraction and expansion that are unforeseeable in the long-term and may affect SQM’s access to financial resources. Such factors may have a material adverse impact on the Company’s business, financial position and results of operations.

SQM constantly monitors the matching of its obligations with its investments, taking due care of maturities of both, from a conservative perspective, as part of this financial risk management strategy. As of December 31, 2018, the Company had unused, available revolving credit facilities with banks, for a total of approximately US$481 million.

The position in other cash and cash equivalents generated by the Company are invested in highly liquid mutual funds with an AAA risk rating.

Pursuant to Article 99 of Law No. 18,045 of the Securities Market (the "Securities Market Law"), the Commission for Financial Market (the "CMF") may determine that a company does not have a controller in accordance with the distribution and dispersion of its ownership. On November 30, 2018, the CMF issued the ordinary letter No. 32.131 whereby it determined that Sociedad de Inversiones Pampa Calichera S.A., Potasios de Chile S.A. and Inversiones Global Mining (Chile) Limitada (the "Pampa Group"), do not exert decisive power over the management of the Company since it does not have a predominance in the ownership that allows it to make management decisions. Therefore, the CMF has determined not to consider Grupo Pampa the controller of the Company and that the Company does not have a controller given its current ownership structure.

## Note 12 Inventories

The composition of inventory at each period-end is as follows:

<table><tr><td>Type of inventory</td><td>12/31/2018</td><td>12/31/2017</td></tr><tr><td></td><td>ThUS\(</td><td>ThUS\)</td></tr><tr><td>Raw material reserves</td><td>6,764</td><td>9,364</td></tr><tr><td>Supplies for production reserves</td><td>26,840</td><td>22,257</td></tr><tr><td>Products-in-progress reserves</td><td>423,621</td><td>456,333</td></tr><tr><td>Finished product reserves</td><td>456,449</td><td>414,120</td></tr><tr><td>Total</td><td>913,674</td><td>902,074</td></tr></table>

As of December 31, 2018, the Company has inventory of caliche ore (in piles or undergoing leaching process) available for processing valued at ThUS$347,100 and ThUS$333,194 as of December 31, 2017, (included in work in progress).

Inventory reserves recognized as of December 31, 2018 amount to ThUS$105,282, and ThUS$96,284 as of December 31, 2017. For finished and in-process products, the provisions constituted include the provision associated with the lower value of stock (considers lower realizable value, uncertain future use, reprocessing costs, etc.), inventory differences and potential errors in the determination of inventories (e.g., errors in topography, grade, humidity, etc.), see Note 3.18.

For inventories of raw materials, supplies, materials and parts, lower value provisions have been associated with the proportion of obsolete, defective or slow-moving materials and potential differences.

The breakdown of inventory reserves is detailed as follows:

<table><tr><td>Type of inventory</td><td>12/31/2018</td><td>12/31/2017</td></tr><tr><td></td><td>ThUS\(</td><td>ThUS\)</td></tr><tr><td>Raw material reserves</td><td>1,838</td><td>93</td></tr><tr><td>Products-in-progress reserves</td><td>82,673</td><td>80,249</td></tr><tr><td>Finished product reserves</td><td>20,771</td><td>15,942</td></tr><tr><td>Total</td><td>105,282</td><td>96,284</td></tr></table>

The Company has not delivered inventory as collateral for the periods indicated above.



## Note 12 Inventories (continued)

As of December 31, 2018 and, 2017, movements in provisions are detailed as follows:

<table><tr><td>Conciliation</td><td>12/31/2018</td><td>12/31/2017</td></tr><tr><td></td><td>ThUS\(</td><td>ThUS\)</td></tr><tr><td>Beginning balance</td><td>96,284</td><td>81,295</td></tr><tr><td>Increase in Lower Value (1)</td><td>7,845</td><td>19,515</td></tr><tr><td>Additional Provision Differences of Inventory. (2)</td><td>3,176</td><td>573</td></tr><tr><td>Increase / Decrease eventual differences and others (3)</td><td>2,436</td><td>(178)</td></tr><tr><td>Provision Used</td><td>(4,459)</td><td>(4,921)</td></tr><tr><td>Total changes</td><td>8,998</td><td>14,989</td></tr><tr><td>Final balance</td><td>105,282</td><td>96,284</td></tr></table>

(1) There are three types of Lower Value Provisions: Economic Realizable Lower Value, Potential Inventory with Uncertain Future Use and Reprocessing Costs of Off-Specification Products.

(2) Provisions for Inventory Differences generated when physical differences are detected when taking inventory, which exceed the tolerance levels for this process. At least two annual inventories are taken in the production sites and in the port in Chile (“zero sum” systems have immediate potential adjustments).

(3) This algorithm corresponds to diverse provision percentages based on the complexity in the measurement and rotation of stock, as well as standard differences based on previous profit and loss, as is the case with provisions in Commercial Offices.



## Note 13 Related party disclosures

## 13.1 Related party disclosures

Balances pending at period-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.

## 13.2 Relationships between the parent and the entity

Pursuant to Article 99 of Law No. 18,045 of the Securities Market (the "Securities Market Law"), the Commission for Financial Market (the "CMF") may determine that a company does not have a controller in accordance with the distribution and dispersion of its ownership. On November 30, 2018, the CMF issued the ordinary letter No. 32.131 whereby it determined that Sociedad de Inversiones Pampa Calichera S.A., Potasios de Chile S.A. and Inversiones Global Mining (Chile) Limitada (the "Pampa Group"), do not exert decisive power over the management of the Company since it does not have a predominance in the ownership that allows it to make management decisions. Therefore, the CMF has determined not to consider Grupo Pampa the controller of the Company and that the Company does not have a controller given its current ownership structure.

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 to hedge the exchange rate financial risks associated with bonds payable. Hedges are documented and tested to measure their 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 and interest payments.

## Hedge Accounting

The Company classifies derivative instruments as hedging that may include derivative or embedded derivatives either as fair value hedge derivative instruments, cash flow hedge derivative instruments, or hedge derivative instruments for net investment in a business abroad.

## a) Fair value hedge

Changes in fair values of derivative instruments classified as fair value hedge derivative instruments are accounted for in gains and losses immediately along with any change in the fair value of the hedged item that is attributable to the risk being hedged.



## Note 14 Financial instruments (continued)

## 14.3 Hedging assets and liabilities, continued

## b) Cash flow hedges

Cash flow hedges cover exposure to the cash flow variations attributable to a risk associated with a specific transaction that is very likely to be executed, which may have material effects on the results of the Company.

The Company documents the relationship between hedge instruments and the hedged item along with the objectives of its risk management and strategy to carry out different hedging transactions. In addition, upon commencement of the period hedged and then on a quarterly basis, the Company documents whether hedge instruments have been efficient and met the objective of hedging market fluctuations. For this purpose, we use the effectiveness test.

The hedge instruments are classified as effective or not effective on the basis of the effectiveness test results. At present, hedges are classified as effective on the basis of the effectiveness tests. This note includes the detail of fair values of derivatives classified as hedging instruments.

## 14.8 Fair value measurement of assets and liabilities

Financial assets and liabilities measured at fair value consist of Options and Forwards hedging the mismatch in the balance sheet and cash flows, Cross Currency Swaps (CCS) to hedge bonds issued in local currency ($/UF), and Interest Rate Swaps (IRS) to hedge LIBOR rate debt issued.

The value of the Company’s assets and liabilities recognized by CCS contracts is calculated as the difference between the present value of discounted cash flows of the asset (pesos/UF) and liability (US\() parts of the derivative. In the case of the IRS, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Options: the value recognized is calculated using the Black-Scholes method.

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

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

The fair value measurement of debt is only performed to determine the present market value of secured and unsecured long-term obligations; bonds denominated in local currency (Ch$/UF) and foreign currency (US$), credits denominated in foreign currency (US$), which is classified under Level 2 in the fair value hierarchy established by IFRS.

The value of the Company’s reported liabilities is calculated as the present value of discounted cash flows at market rates at the time of valuation, taking into account the maturity date and exchange rate. The entry data used for the model includes the UF and peso rates, which are obtained using Bloomberg, the well-known financial software company and the ‘Asociación de Bancos e Instituciones Financieras’ (ABIF) (Association of Banks and Financial Institutions’).

## 14.8 Fair value measurement of assets and liabilities, continued

## Fair value hierarchy

The fair value hierarchy is detailed as follows:

a) Level 1: using quoted prices (unadjusted) only in active markets,

b) Level 2: when in any phase in the valuation process inputs other than quoted prices have been used in Level 1 that are observable directly in markets.

c) Level 3: inputs for the asset or liability that are not based on observable market data.

The valuation technique used for determining fair value of our hedging instruments is that indicated in Level 2.

## 14.10 Estimated fair value of financial instruments and financial derivatives

As required by IFRS 7, 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.

The fair value of trade receivables, current is considered to be equal to the carrying amount due to the maturity of such accounts at short-term.

The fair value of other current financial liabilities is considered to be equal to their carrying values.

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

- The fair value of debt is considered in Level 2.

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

## a) Estimated useful lives or amortization rates used for finite identifiable intangible assets

Finite useful life measures the length of, or number of production or similar units constituting that useful life.

The estimated useful life for software is 2-6 years, for other assets with a finite useful life, the useful life over which they are amortized corresponds to the periods defined by the contracts or rights from which they originate.

Intellectual property rights, patents and other industrial property rights, service and exploitation rights, mainly relate to water rights and have a finite useful life to the extent to which they are subject to a fixed-term contract or otherwise they are considered to be indefinite.

The company owns mining claims granted by Corfo, which correspond to assets subject to restitution. For this reason they are considered assets with a finite useful life and their useful life is assigned until the year 2030 when the contract ends.

## b) Method used to assess identifiable intangible assets with indefinite useful life

The recoverable value of the cash-generating unit has been determined based on a calculation of value-in-use using cash flow projections for a period of 5 years, plus perpetuity. The present value of future cash flows generated by these assets was calculated given a variation in sales volumes, market prices and costs, discounted at a WACC rate of 8.04%.

This group of intangible assets includes water rights acquired in Chile, and mining concessions held by the company in Chile and Australia, and these rights are recorded at acquisition cost.

(*) The net balance of other increases (decreases) corresponds to all those items that are reclassified to or from property, plant and equipment. They can have the following origin:1) work in progress which is expended to profit or loss, forming part of operating costs or other expenses per function, as appropriate; 2) the variation representing the purchase and use of materials and spare parts; 3) projects corresponding mainly to exploration expenditures and ground studies that are reclassified to the item other non-current financial assets; 4) software that is reclassified to Intangibles.

(1) Any property, plant and equipment (disposal group) that, at the closing date of the financial statements, is subject to a commitment for sale or where the sales process has been initiated and where the sale is expected to occur within twelve months of that date, is classified by the Company as non-current assets held for sale.

These assets or disposal groups are valued at the lower of carrying amount or the estimated sales value less the costs to sell and stop being amortized from the moment they are classified as non-current assets held for sale.

## 18.2 Policies on defined benefit plan

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 and other types of leave, 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, with the exemption of SQM North America, which applies the definitions under 18.4 below.

SQM maintains incentive programs for its employees based on their personal performance, the Company’s performance and other short-term and long-term indicators.

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 each employee’s appraisal process.

Employee benefits include retention bonuses for the Company’s executives, which are linked to the Company’s share price and are paid in cash. The short-term portion is presented as a provision for current employee benefits and the long-term portion as non-current.

Staff severance indemnities are agreed and payable based on the final salary, calculated in accordance with each year of service to the Company, with certain maximum limits in respect of either the number of years or in monetary terms, In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and there are a number of different circumstances through which a person can be eligible for it, 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 dependent employees regulated by the Chilean Labor Code. Article 5 of this law established that this insurance is paid through monthly contribution payments by both the employee and the employer.



## Note 18 Employee benefits (continued)

## 18.3 Other long-term benefits

The other long-term benefits relate to staff severance indemnities and are recorded at their actuarial value, and an executive compensation plan (see Note 18.6).

<table><tr><td rowspan="2">Staff severance indemnities at actuarial value</td><td>12/31/2018</td><td>12/31/2017</td></tr><tr><td>ThUS\(</td><td>ThUS\)</td></tr><tr><td>Staff severance indemnities, Chile</td><td>27,562</td><td>25,893</td></tr><tr><td>Executive severance plan</td><td>8,831</td><td>6,487</td></tr><tr><td>Severance for foreigners</td><td>671</td><td>1,552</td></tr><tr><td>Total other non-current liabilities</td><td>37,064</td><td>33,932</td></tr></table>

The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting 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.

Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, 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 4,89%.

## Benefit payment conditions

The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system as established in Decree Law 3,500 of 1980.

## Methodology

The Company’s benefits obligation under IAS 19 Projected Benefit Obligation (PBO) is determined as follows:

To determine the Company’s total liability, we used computer software to develop a mathematical simulation model using the data for each individual employee.



## Note 18 Employee benefits (continued)

## 18.3 Other long-term benefits, continued

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. This information on each person was simulated from the beginning of his/her employment contract or when he/she started earning benefits up to the month in which he/she reaches 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 a retirement indemnity.

The methodology followed to determine the accrual for all the employees covered by agreements took account of the turnover rates and the mortality rate RV-2009 established by the CMF 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 on Retirement Benefit Costs.

## 18.4 Post-employment benefit obligations

Our subsidiary SQM North America, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”. This obligation is calculated measuring the expected future forecast staff severance indemnity obligation using a net salary gradual rate of restatements for inflation, mortality and turnover assumptions, discounting the resulting amounts at present value using the interest rate defined by the authorities.

Since 2003, SQM North America offers to its employees benefits related to pension plans based on the 401-K system, which do not generate obligations for the Company.

## Note 18 Employee benefits (continued)

## 18.6 Executive compensation plan

The Company currently has a compensation plan with the purpose of motivating the Company’s executives and encouraging them to remain with the Company, by granting payments based on the change in the price of SQM’s shares. There is a partial payment of the share benefit program in the event of termination of the contract for causes other than the resignation and application of Article 160.

## Average Share Price Spread

## Plan characteristics

This compensation plan is related to the Company’s performance through the SQM Series B share price (Santiago Stock Exchange).

## Plan participants

A total of 37 Company executives are entitled to this plan, provided that they continue to work for the Company through to the end of 2020. The payment dates, if applicable, will be during the first quarter of 2021.

## Compensation

The compensation payable to each executive is calculated by multiplying a) by b):

a) The average price of Series B shares on the Santiago Stock Exchange during the fourth quarter of 2020, at its equivalent amount in dollars (with a maximum amount or limit amount of US$54 per share).

b) By a number equal to the quantity of shares that have been individually assigned to each executive included in the plan.

This compensation plan was approved by the Company’s Board of Directors and its application started on January 1, 2017.

The effect of the plan considers 476,302 shares reflected as a cost of ThUS$3,754 in the results for the period ending December 31, 2018. As of December 31, 2017, the effect of the plan was 533,476 shares, equal to ThUS$6,487 in costs in the profit or loss for 2017.

## 20.1 Capital management

The main object of capital management relative to the administration of the Company’s financial debt and equity is to ensure the regular conduct of operations and business continuity in the long term, with the constant intention of maintaining an adequate level of liquidity and in compliance with the financial safeguards established in the debt contracts in force. Within this framework, decisions are made in order to maximize the value of SQM.

Capital management must comply with, among others, the limits contemplated in the Financing Policy approved by the Shareholders' Meeting, which establish a maximum consolidated indebtedness level of 1.5 times the debt to equity ratio. This limit can be exceeded only if the Company’s management has first obtained express approval at an Extraordinary Shareholders' Meeting.

In addition, capital management must comply with the external capital requirements (or covenants) imposed in its financial obligations, which regulate the indebtedness level to 1.2 times, its strictest level.

In conjunction with the level of indebtedness, it is also important for the Company to maintain a comfortable profile of maturities for its financial obligations, in order to oversee the relation between its short-term financial obligations and the long-term maturities, and the relation they have with the Company’s asset distribution. Consequently, the Company has maintained a liquidity level of 3 times during the last periods.

The Company’s management controls capital management based on the following ratios:

<table><tr><td>CAPITAL MANAGEMENT</td><td>12/31/2018</td><td>12/31/2017</td><td>Description (1)</td><td>Calculation (1)</td></tr><tr><td>Net Financial Debt ThUSS</td><td>471,755</td><td>245,508</td><td>Financial Debt - Financial Resources</td><td>Other current Financial Liabilities + Other Non-Current Financial Liabilities - Cash and Cash Equivalents - Other Current Financial Assets - Hedging Assets, non-current</td></tr><tr><td>Liquidity</td><td>4.32</td><td>3.29</td><td>Current Assets divided by Current Liabilities</td><td>Total Current Assets / Total Current Liabilities</td></tr><tr><td>Net Debt / Capitalization</td><td>0.18</td><td>0.10</td><td>Net Financial Debt divided by Total Equity</td><td>Net financial debt / Total Equity</td></tr><tr><td>ROE</td><td>20.7%</td><td>19.1%</td><td>Profit for the year divided by Total Equity</td><td>LTM(2) Profit for the year / Equity</td></tr><tr><td>Adjusted EBITDA (ThUSS)</td><td>885,652</td><td>901,856</td><td>Adjusted EBITDA</td><td>Profit for the year + Depreciation and Amortization Expenses + Finance Costs + Income Tax - Other income and Share of profit of associates and joint ventures + Other expenses - Finance income - Currency differences</td></tr><tr><td>EBITDA (ThUSS)</td><td>902,450</td><td>885,240</td><td>EBITDA</td><td>Profit for the year + Depreciation and Amortization Expenses + Finance Costs + Income Tax</td></tr><tr><td>ROA</td><td>20.31%</td><td>21.3%</td><td>Adjusted EBITDA - Depreciation divided by Total Assets net of financial resources less related parties&#x27; investments</td><td>(LTM Gross Profit - Administrative Expenses) / (Total Assets - Cash and Cash Equivalents - Other Current Financial Assets - Other Non-Current Financial Assets - Equity-accounted Investments)</td></tr><tr><td>Indebtedness</td><td>1.00</td><td>0.91</td><td>Total Liabilities on Equity</td><td>Total Liabilities / Total Equity</td></tr></table>

## 20.1 Capital management, continued

The Company’s capital requirements change according to variables such as working capital needs, new investment financing and dividends, among others. The Company manages its capital structure and makes adjustments on the basis of the predominant economic conditions so as to mitigate the risks associated with adverse market conditions and take advantage of the opportunities there may be to improve the liquidity position.

There have been no changes in the capital management objectives or policy within the years reported in this document. No breaches of external requirements of capital imposed (or covenants) have been recorded.

(b) require the calling of an extraordinary meeting of the board of directors, without the president being able to qualify the need for such a request, when so requested by the director who has been elected by the shareholders of said Series B.

The limitation and preferences of Series B shares have a duration of 50 consecutive and continuous years as of June 3, 1993.

The Series A shares have the preference of being able to exclude the director elected by the Series B shareholders in the voting process in which the president of the board of directors and of the Company must be elected and which follows the one in which the tie that allows such exclusion resulted.

The preference of the Series A shares will have a term of 50 consecutive and continuous years as of June 3, 1993. The form of the titles of the shares, their issuance, exchange, disablement, loss, replacement, assignment and other circumstances thereof shall be governed by the provisions of Law No. 18,046 and its regulations.

## Reserves for foreign currency translation differences

This balance reflects retained earnings for changes in the exchange rate when converting the financial statements of subsidiaries whose functional currency is that of each company’s origin country and the presentation currency is the US dollar.

## Reserve for cash flow hedges

The Company maintains, as hedge instruments, financial derivatives related to obligations with the public issued in UF and Chilean pesos. Changes from the fair value of derivatives designated and classified as hedges are recognized under this classification.

## Reserve for gains and losses from financial assets measured at fair value through other comprehensive income

This caption includes investments in shares where the Company has no significant influence and these have accordingly been measured at fair value through equity. In the event that such equity instruments are fully or partially disposed of, the proportional accumulated effect of accumulated fair value will be transferred to profit or loss.

## Reserve for actuarial gains or losses in defined benefit plans

For domestic subsidiaries the effects of changes in assumptions are considered, mainly changes in the discount rate.

The subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation of staff severance indemnities using a net salary progressive rate net of adjustments to inflation, mortality and turnover assumptions, deducting the resulting amounts at present value using a 5.5% interest rate for 2017 and 2016.

## 20.4 Dividend policies

As required by Article 79 of the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued and subscribed shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated profit for the year ended as of December 31, unless and except to the extent it has a deficit in retained earnings (losses not absorbed in prior years).

## Dividend policy for commercial year 2018.

The Company has defined the following dividend policy:

a) Distribute and pay, as a final dividend (dividendo definitivo) and in favor of the respective shareholders, a percentage of the net income that shall be determined per the following financial parameters:

(i) 100% of the 2018 net income, when the following financial parameters are met: (a) that the total sum of cash and cash equivalent, and other current financial assets (“Cash”) divided by the total sum of the current financial liabilities (“Current Financial Liabilities”) is equal to or greater than 2.5 times, and (b) the total sum of the current liabilities and the non-current liabilities (“Total Liabilities”) divided by the total sum of the equity (“Equity”) is equal to or less than 1.1 times.

(ii) 80% of the 2018 net income when the following financial parameters are met: (a) that Cash divided by Current Financial Liabilities is equal to or greater than 2.0 times, and (b) the total sum of the Total Liabilities divided by the total Equity is equal to or less than 1.2 times.

(iii) 60% of the 2018 net income when the following financial parameters are met: (a) that Cash divided by Current Financial Liabilities is equal to or greater than 1.5 times, and (b) Total Liabilities divided by Equity is equal to or less than 1.3 times.

If none of the foregoing financial parameters are met, the Company shall distribute and pay, as a final dividend, and in favor of the respective shareholders, 50% of the 2018 net income.

b) Distribute and pay, if possible and during 2018, three interim dividends (dividendos provisorios) that will be charged against the aforementioned final dividend. These interim dividends shall likely be paid during the month following the approval of the March, June, and September 2018 interim financial statements, respectively. Its amounts shall be calculated as follows:

(i) For the interim dividends that will be charged to the accumulated net income reflected in the March 2018 interim financial statements, the percentage distributed shall be determined per the financial parameters expressed in letter a) above.

(ii) For the interim dividends that will be charged to the accumulated net income reflected in the June 2018 interim financial statements, the percentage distributed shall be determined per the financial parameters expressed in letter a) above, discounting the total amount of interim dividends previously distributed during 2017.



## Note 20 Disclosures on equity (continued)

## 20.4 Dividend policies, continued

(iii) For the interim dividends that will be charged to the accumulated net income reflected in the September 2018 interim financial statements, the percentage distributed shall be determined per the financial parameters expressed in letter a) above, discounting the total amount of interim dividends previously distributed during 2018.

c) The amount of the interim dividends mentioned above may vary, pursuant to the information available to the Board of Directors on the date on which it agrees to the distribution of said dividends given that the dividend will not materially or negatively affect SQM’s capacity to impact its investments, fulfill its liabilities, or in general, comply with the investment and finance policy approved at the ordinary shareholders’ meeting.

d) At the ordinary shareholders meeting that will be held in 2019, the Board of Directors shall propose a final dividend pursuant to the financial parameters expressed in letter a) above, discounting the total amount of the interim dividends previously distributed during 2018.

e) If there is an excess of net income in 2018, this may be retained and assigned or allocated for financing its own operations, to one or more investment projects of the Company, notwithstanding a future distribution of special dividends (dividendos eventuales) charged to the accumulated net income previously approved at the shareholders' meeting, or the possible and future capitalization of all or part of the latter.

f) The payment of additional dividends (dividendos adicionales) is not considered.

The dividend policy described above corresponds to the intention of the Board of Directors, and the compliance of it shall depend on the net income that the Company ultimately obtains, as well as the results of periodic projections that could impact the Company, or to the existence of determined conditions that may affect it, as applicable. If the dividend policy exposed by the Board of Directors suffers a substantial change, the Company must communicate it as an essential fact.

The Company and its subsidiaries have been involved and will probably continue to be involved either as plaintiffs or defendants in certain judicial proceedings that have been and will be heard by the arbitration or ordinary courts of justice that will make the final decision. Those proceedings that are regulated by the appropriate legal regulations are intended to exercise or oppose certain actions or exceptions related to certain mining claims either granted or to be granted and that do not or will not affect in an essential manner the development of the Company and its subsidiaries.

Soquimich Commercial S.A. has been involved and will probably continue being involved either as plaintiff or defendant in certain judicial proceedings through which it intends to collect and receive the amounts owed, the total nominal value of which is approximately US$1.2 million.

The Company has made efforts and continues making efforts to obtain payment of certain amounts that are still owed to the Company due to its activities. Such amounts will continue to be required using judicial or non-judicial means by the plaintiffs, and the actions and exercise related to these are currently in full force and effect.

The Company and its subsidiaries have received no legal notice on lawsuits other than those indicated above, which exceed US$0.2 million.

## 22.2 Restrictions to management or financial limits

Contracts that subscribed the issuance of bonuses in the local and international market require the Company to comply with the following level of consolidated financial indicators, calculated for the last 12 month period:

To maintain Leverage Ratio not higher than 1.2 times at its strictest level. The Leverage ratio is defined as the Total Liabilities divided by Total Equity.

In addition, SQM S.A. is committed to disclosing financial information on quarterly basis.

The Company and its subsidiaries have complied and are fully complying with all the aforementioned limitations, restrictions and obligations.



## Note 22 Contingencies and restrictions (continued)

## 22.3 Environmental contingencies

On June 6, 2016, the “SMA” filed charges against the Company with respect to the Pampa Hermosa project for possible noncompliance with RCA 890/2010.

This relates to charges related to certain variables of the follow-up plan and the implementation of a mitigation measure included in the respective environmental impact assessment. The Company has presented for the approval of SMA a compliance program detailing the actions and commitments it will carry out to address the SMA’s objections.

On June 29, 2017, the SMA rejected the compliance program presented by the Company. On July 10, 2017, the Company presented its rebuttals to the charges made by the SMA. On August 21, 2018, the Second Environmental Court accepted the Company’s claim, ordering the SMA to take the procedure back to the stage prior to their resolution rejecting the compliance program presented by the Company.

On December 13, 2017, the First Environmental Court of Antofagasta authorized the SMA to apply the temporary and partial closure of the water extraction wells located in the Salar de Llamara. These wells allow the Company to extract around 124 liters/second of water, which is approximately 15% of the water used in Chile’s First Region. In October 2018, the First Environmental Court of Antofagasta accepted the Company’s claim, leaving the indicated closure without effect, maintaining only the requirement to prepare reports to increase knowledge of ecosystems. In mid-October, the Court denied authorization to SMA to renew the closure measure. In December 2018, the First Environmental Court accepted the Company’s second claim, ratifying the previous decision.

On January 10, 2019, the SMA carried out the sentence of the Second Environmental Court, taking the procedure back to the stage prior to their resolution rejecting the compliance program presented by the Company. On January 14, 2019, the SMA made new observations to the compliance program formulated by the Company. The term granted for the Company to address these observations is currently underway, after which the SMA will issue a new ruling on the proposal.

Through a ruling dated November 28, 2016, which was modified by a ruling dated December 23, 2016, the SMA filed charges against SQM Salar for extracting brine in excess of authorized amounts, progressively impacting the vitality of algarrobo trees, delivering incomplete information, modifying variables and other matters.



## Note 22 Contingencies and restrictions (continued)

## 22.3 Environmental contingencies, continued

SQM Salar presented a compliance program that details the actions and commitments that will be undertaken to overcome the objections formulated by the SMA. This program was accepted by SMA ruling dated January 7, 2019, thus suspending the process initiated against SQM Salar. The Atacameño Indigenous Community of Peine, the Indigenous Association Council of Atacameño Peoples and the Atacameño Indigenous Community of Camar have filed against this ruling with the First Environmental Court. In keeping with the monitoring plans established in the current environmental qualification resolution for the operation at the Salar de Atacama, SQM Salar periodically monitors the flora, fauna, hydrogeological and meteorological variables, including 225 monitoring points and 48 continuous measuring points for the brine and water levels in different parts of the salar basin, which it periodically reports to the corresponding authorities. If any of the monitoring points fall below predefined levels, various actions are considered, which are part of the environmental monitoring plan.

On May 20, 2018, 2 of the 225 points were 1 cm below the predefined level for those points. These points are on the route of an outlet sector for a lagoon located on the eastern edge of the Salar de Atacama. Historically flows from the lagoons of the deposit have varied in location and route. That has happened in this case and the flow has moved with regard to the location of the monitoring well in question. Both the levels and the flows from the lagoons have behaved normally and no changes in the ecosystem that is being monitored in the area have been observed.

Following the protocols established for these cases, SQM Salar’s total extraction volume in the Salar de Atacama, has been reduced from a maximum average of 1,500 liters per second per year to 1,250 liters per second per year for a period of six months.

The Company estimates that an average annual decrease of brine extraction of 250 liters per second would have no impact on current and estimated production volumes of lithium carbonate and hydroxide. In the case of potassium chloride, it is estimated that the reduction in brine extraction could imply a reduction in production and sales volumes of approximately 170.000 metric tons on an annual basis.

## 22.4 Tax contingency

During 2015, the Company, SQM Salar and SQM Industrial submitted to the Chilean IRS four tax amendments (two by the Company, one by SQM Salar and one by SQM Industrial).

The first two (one for SQM and one for SQM Salar), after being approved by the SII, generated payments for taxes, interests and other charges of US$8.1 million. A provision for such amount was made in the profit or loss for the first quarter of 2015.

Additionally, during August 2015, the Chilean IRS was provided, for its review and approval, with the documentation necessary for amending the annual tax returns of the Company and SQM Industrial. As a result of such amendments, the Company paid an approximate amount of US$1.4 million for taxes, interests and other charges. This amount was recorded in a provision in the profit or loss for the second quarter of 2015.

Finally, during 2016, the last 12 invoices were amended with a payment of approximately US$50,000.

Accordingly, the SQM Group considers terminated the internal analysis which has been performed. The purpose of the analysis was to identify the expenses incurred by the SQM Group during the fiscal years 2008 to 2014 and which could be a matter of tax rectification.



## Note 22 Contingencies and restrictions (continued)

## 22.4 Tax contingency, continued

Because of the aforementioned amendments, the Company, SQM Salar and SQM Industrial might be affected by additional penalties established in the first subparagraph, No. 4 of Article 97 of the Tax Code, for an amount ranging between 50% and 300% of the taxes paid. The Company has not considered it necessary to make any provisions related to this possible additional penalty.

On Friday, August 26, 2016, SQM Salar filed with the Third Tax and Customs Court of the Metropolitan Region a tax claim against tax assessments No. 169, 170, 171 and 172, which seek to expand application of the specific tax on mining activities to include lithium exploitation. The amount involved is approximately US$17.8 million. On November 28, 2018, the Third Tax and Customs Court rejected the claim, and the case is in the Santiago Court of Appeals, based on the appeal filed by SQM Salar.

On March 24, 2017, SQM Salar filed with the Third Tax and Customs Court of the Metropolitan Region a tax claim against tax assessment No. 207 of 2016 and ruling No. 156 of 2016, both issued by the Chilean IRS, which seek to expand application of the specific tax on mining activities to include lithium exploitation for tax years 2015 and 2016. The amount involved is approximately US$14.4 million. On November 28, 2018, the Third Tax and Customs Court accepted SQM Salar’s claim for US$7.0 million corresponding to the overcharge made by the SII and rejected the remainder of the claim. The case is in the Santiago Court of Appeals, based on the appeal filed by SQM Salar.

These amounts are classified as taxes for current assets, non-current, as of December 31, 2017 and the same as of December 31, 2018.

The amount involved is approximately US$32.2 million. The Chilean IRS has not issued an assessment claiming differences in the specific tax on mining activities filed for business years 2016, 2017 and 2018. As of the date of these financial statements, the Company has not made any provisions for these possible differences.

If the Chilean IRS uses criteria similar to that used in previous years, it may issue an assessment in the future for the 2016, 2017 and 2018 financial years. It is reasonable to expect that should these assessments for the period 2016 to the quarter half of 2018 be issued, the value would be approximately US$57 million (without considering potential interest and fines).

## 22.5 Contingencies regarding the Changes to the Contracts with Corfo. Appeal No. 10301-2018, Santiago Court of Appeals:

(a) In January 2018, indigenous communities and various parties presented an appeal for legal protection against Corfo, the Company, SQM Salar and SQM Potasio (the “Companies”), with regard to the amendments to the contract for the project in the Salar de Atacama and the OMA mining property lease contract dated January 17, 2018, both granted as a result of a conciliation process proposed by the arbitration court which took place at the end of arbitration between the parties (the “Amendments”). According to the appellants, the Amendments will deprive, disturb and threaten in an illegal and arbitrary way the constitutional rights of the appellants established in article 19, numbers 8, 21 and 24 of the Political Constitution. The appellants have therefore requested the following: (i) that the acts subject to appeal be declared invalid, vacated or without effect, (ii) that the Amendments be reviewed according to the provisions of Convention 169 (iii) that the counterparts be expressly made liable for the costs, given the clearly illegal and arbitrary nature of what has occurred.

Once informed of the appeal, the Companies requested that it be rejected for the following reasons. Firstly because it is extemporaneous. Secondly, as the matter is one that requires the interpretation and verification of the application or effects of contractual clauses, it goes beyond the scope of this cautionary action. Thirdly it should be challenged on the principle of specialty, because there is a special procedure which would better apply. In terms of substance, the Companies have indicated to the Court that an increase in the lithium quota, authorized through contractual changes adopted through a conciliation process proposed by the Arbitration Judge does not constitute an arbitrary or illegal act and that no indigenous consultation took place as per article 6 of Convention 169 because the Amendments were not legislative or administrative measures likely to directly affect the indigenous peoples. The Companies have sustained that the Amendments are the implementation of a conciliation agreement, that is the jurisdictional equivalent of res judicata, which was proposed by the arbitration judge and does not correspond to the exercise of public powers, as required in article 6 of Convention 169.

On September 25, 2018, the Santiago Court of Appeals rejected the appeal for protection. The appeal for protection is currently pending before the Supreme Court.



## Note 22 Contingencies and restrictions (continued)

## 22.5 Contingencies regarding the Changes to the Contracts with Corfo. Appeal No. 10301-2018, Santiago Court of Appeals (continued)

In the event that a ruling is made to leave without effect the Amendments and if there are no appeals by the parties, the contracts prior to the Amendments will once again be valid, although this resolution should not affect the efficiency and validity of the conciliation reached regarding the matters debated in arbitration.

The court has the faculties to adopt the decisions it considers necessary to reestablish the rule of law and ensure the protection of the affected party.

(b) On September 6, 2018, a public law annulment lawsuit was filed by the congresspersons Mss. Claudia Nathalie Mix Jiménez, Gael Fernanda Yeomans Araya and Camila Ruslay Rojas Valderrama and the Citizen Power Party (Partido Poder Ciudadano) to render null and void the contract for the Salar de Atacama Project signed between Corfo and the Companies. The Companies have joined the suit as interested third parties.

In the suit, the plaintiffs request a pretrial measure against Corfo for the signing of agreements and contracts related to the exploitation of lithium. On October 31, 2018, the special magistrate rejected the measure, which was appealed by the plaintiffs.

In the event that the contract for the Salar de Atacama Project is rendered null and void, SQM Salar could be unable to exploit the mining claims in the Salar de Atacama that it has leased from Corfo.

## Lawsuits and complaints

During 2015, the Chilean IRS filed several lawsuits and complaints against a number of individuals related to the so-called “SQM Case”, which were associated with the irregular financing of politicians. Amongst those affected by these legal claims were the legal representatives of the Company then the CEO, Patricio de Sominihac T. and the Vice President of Corporate Services, Ricardo Ramos R. today Chief Executive Officer Those lawsuits and complaints related to alleged tax crimes associated with a possible undue decrease in the taxable net income of the Company and two of its subsidiaries over the last seven years by recording as expenses various invoices and fee receipts, which could be considered as ideologically false. Similar legal actions were also filed against the taxpayers who provided the tax documents that allowed the alleged commission of the related illicit acts.

## Actions performed by the Authority and Termination of research in Chile

The Public Ministry and the Chilean IRS (Servicio de Impuestos Internos (SII) have performed a number of actions within the framework of the so-called “SQM Case”, where the Company and its executives have provided their cooperation. Several of the Company’s executives have granted access to their computers and made several statements at the request of the Prosecutors responsible for the investigation. Additionally, SQM has provided physical and digital copies of its accounting records and its subsidiaries’ accounting records. SQM has also provided the Public Ministry with its email files and all the documentation that has been requested by the authority.

On August 17, 2018, the Eighth Guarantee Court declared the definitive dismissal of the Company, SQM Salar and SQM Nitratos with respect to the case in which their criminal liability was being investigated.

On January 15, 2019, the MP communicated to the Eighth Criminal Court its decision not to continue with the criminal investigation against Messrs. Patricio de Solminihac T., Ricardo Ramos R. and Enrique Olivares C.



## Note 23 Lawsuits and complaints, (continued)

## Shearman & Sterling and Ad-Hoc Committee

On February 26, 2015, the Board of Directors of SQM established an ad-hoc committee comprised of three directors (the “Ad-hoc Committee”), which was authorized to conduct an investigation on the matters described in the preceding paragraph and to request any external advisory services it deemed necessary. The original members of the Ad-hoc Committee were José María Eyzaguirre B., Juan Antonio Guzmán M., and Wolf von Appen B.

The Ad-hoc Committee hired its own legal counsel in Chile and the United States as well as forensic accountants in the United States to support its internal investigation. The U.S. attorneys hired by the Ad-hoc Committee were mainly charged with reviewing the important facts and analyzing them in the context of the United States Foreign Corrupt Practices Act (“FCPA”). However, the Ad-hoc Committee’s factual conclusions were shared with both Chilean authorities and U.S. authorities.

On December 15, 2015, the Ad-hoc Committee presented the conclusions of its investigation to the Board of Directors. In addition to discussing the facts related to the referenced payments, the Ad-hoc Committee concluded that, for the purposes of the FCPA:

a. payments were identified that had been authorized by the former CEO of SQM for which the Company did not find sufficient supporting documentation;

b. no evidence was identified that demonstrated that such payments were made in order to prompt a public official to act or abstain from acting in order to help SQM obtain economic benefits;

c. in relation to the cost centers managed by the former CEO of SQM, it was concluded that the Company's books did not accurately reflect the transactions in question but that these transactions were determined to be quantitatively immaterial in comparison to SQM's equity, sales, expenses and profits during that period; and that.

d. SQM's internal controls were insufficient to supervise the expenses within the cost center managed by the former CEO of SQM and relied on the proper use of resources by Patricio Contesse G. himself.

After the Ad-hoc Committee presented its conclusions to the Board of Directors, the Company voluntarily shared these conclusions with the Chilean and U.S. Authorities (including the Securities and Exchange Commission (the “SEC”) and the U.S. Department of Justice (the “DOJ”) and has since collaborated by handing over documents and additional information requested by these authorities regarding this investigation.



## Note 23 Lawsuits and complaints, (continued)

## Investigation by the Department of Justice and the Securities Exchange Commission and Agreements

The Company reported on the investigation by Shearman & Sterling for North American regulatory entities (DOJ and Securities and Exchange Commission, the “SEC”), in accordance with the regulations in force in the United States of America. The results of this investigation were given to these regulatory entities, which have opened investigations to determine the existence of possible noncompliance with the FCPA or Internal control standards.

On January 13, 2017, the Company and the DOJ reached agreement on the terms of a Deferred Prosecution Agreement (the “DPA”) that would resolve the DOJ’s inquiry, based on alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act. Among other terms, the DPA calls for the Company to pay a monetary penalty of US$15,487,500, and engage a compliance monitor for a term of two (2) years. Upon successful completion of the three (3) year term of the DPA, all charges against the Company would be dismissed. On the same date, the SEC agreed to resolve its inquiry through an administrative cease and desist order, arising out of the alleged violations of the same accounting provisions of the FCPA. Among other terms, the SEC order calls for the Company to pay an additional monetary penalty of US$15 million. These penalties were reflected in the 2016 financial statements.

In accordance with the terms of the Deferred Prosecution Agreement (the “DPA”) with the DOJ, the Company has accepted that the DOJ formulates (i) a charge for infractions for the lack of implementation of effective internal accounting systems and internal accounting controls and (ii) a charge for infractions for failure to adequately maintain books, records and accounting sections in relation to the events investigated. Under the DPA, the DOJ has agreed not to pursue such charges against the Company for a period of 3 years and release the Company from liability after such period, inasmuch as within that period the Company complies with the terms of the DPA. These include payment of a fine of US$15,487,500 and acceptance of an external monitor for a period of 24 months (the “Monitor”) that will assess the Company’s compliance program, and continue to report on the Company independently for an additional year.

In relation to the agreement with the SEC, the Company has agreed to (i) pay a fine of 15 million dollars and (ii) maintain the Monitor for the aforementioned period.

The SEC has issued a Cease and Desist Order that does not identify other breaches of United States regulations.

The aforementioned amounts, approximately US$30.5 million, were reflected in the Company’s profit and loss during the fourth quarter of 2016 in the Other Expenses by function line.



## Note 24 Sanction proceedings

On April 03, 2018, the National Directorate of the “Dirección Nacional del Servicio Nacional de Geología y Minería” (National Geology and Mining Service) filed charges against SQM Industrial for the alleged violation of Article 40 letter c) of Law No. 20,551 that regulates the closure of mining works and facilities for Pampa Blanca, located in the district of Sierra Gorda. On April 26, 2018, SQM Industrial gave its deposition. According to current regulations, the National Geology and Mining Service can impose fines of up to 10 UTMs (monthly tax units) for each day of infringement, with a total maximum of 10,000 UTMs per month.

The Company is currently operating under an Environmental Management System (EMS) that has allowed it to strengthen 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.

Many of the Company’s products are shipped in bulk at the Port of Tocopilla. In 2007, the city of Tocopilla was declared a zone saturated with MP10 Particles mainly due to the emissions from the electric power plants that operate in that city. In October 2010, the Decontamination Plan for Tocopilla was put in place. Accordingly, the Company has committed to taking several measures to mitigate the effects derived from bulk product movements in the port. These measures have been timely implemented since 2007.

The Company carries out environmental follow-up and monitoring plans based on specialized scientific studies. Within this context, the Company 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 the Pontificia Universidad Católica in Santiago and the School of Agricultural Science of the Universidad de Chile.

Furthermore, within the framework of the environmental studies which the Company is conducting, the Company performs 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 Maria Elena and the Nueva Victoria plant. This effort is being accompanied by cultural initiatives within the community and the organization of exhibits in local and regional museums.

As emphasized in its Sustainable Development Policy, the Company strives to maintain positive relationships with the communities surrounding the locations in which it carries out its operations, as well as to participate in communities' development by supporting joint projects and activities which help to improve the quality of life for residents. For this purpose, the Company has focused its efforts on activities involving the rescue of historical heritage, education and culture, as well as development.

In order to do so, it acts both individually and in conjunction with private and public entities.

## 25.3 Description of each project, indicating whether these are in process or have been finished

## SQM S.A.

I0055: In the  \( SO_{2} \)  plant, the gas/liquid ratio is deficient, preventing the absorption of  \( SO_{2} \) ; producing a loss of free iodine through inadequate stripping of kerosene and prilling air. This also causes the ducts and furnaces to be blocked (unplanned shutdowns), a very polluted environment for people (aberration in health and hygiene), excessive acid rain (corrosion of facilities) and a high sulfur and sodium metabisulfite consumption factor. By changing the gas extractors to increase air flows and the  \( SO_{2} \)  absorption towers for prilling, the diameter of the ducts will be increased. This will ensure that the gas/liquid ratio is increased and sustained. In order to decrease  \( SO_{2} \) , emissions, a scrubber unit (tower, pump, gas extractor and piping) needs to be installed following the same concept as was developed at the ME Iodine  \( SO_{2} \)  plant.

I0073: The system for capturing iodine gases is operating very inefficiently. The iodine steam levels are between 150% and 4,900% above the levels allowed for jobs at iodine plants and warehouses as established in Article 61 of Supreme Decree No, 594/1999, approving Basic Sanitary and Environmental Conditions in Workplaces. This project is in progress.

I0122: The project consists of repairing and/or replacing the environmental follow-up wells that need to be deepened. It also includes implementing improvements in mine shaft type wells to avoid risk conditions. The priority wells are Nos. 8 and 10-S-1 in Pampa del Tamarugal and PO-5 in Salar de Llamara.

I0138: This project is to increase the height of each  \( SO_{2} \)  absorber tower (regular and stand-by towers) by 2,5 meters. The towers’ additional height will allow the height of the packing to be increased by 2,5, thereby improving the efficiency of the  \( SO_{2} \)  absorption. The main activities are: Basic and detailed engineering; supply of the bodies of the absorber towers (frp), liquid distributors, tower brine pump pad, tri-pack packing type, polyethylene pipes and fitting; gas measurement service; metallic structure manufacturing and installation services; and project start-up.

I0172: The commitments of the Pampa Hermosa project for the Salar de Llamara include the Tamarugos Environmental Management Plan (PMAT), which contemplates an Environmental Education Program that includes the design, construction and start-up of an Environmental Education Center (CEDAM) at Puquios de Llamara. Conceptual design, detailed design, construction and start-up are necessary for the CEDAM, which will be subject to approval by the authorities so its duration and costs are subject to the approval of third parties.

## Note 26 Mineral resource exploration and evaluation expenditure

Given the nature of operations of the Sociedad Química y Minera de Chile S.A. and Subsidiaries and the type of exploration it undertakes, disbursements for exploration can be found in 4 stages: Implementation, economically feasible, not economically feasible and in exploitation:

1. Implementation: Disbursements for prospecting under implementation and therefore prior to determination of economic feasibility, are classified in the caption of Non-Current Assets, found in Works in Progress for Properties, Plant and Equipment, which include, exploration of caliche, and brine from the Salar de Atacama (these processes are generally developed over a one-year period), both totaling ThUS$8,355 in this caption, as of December 31, 2018, and ThUS$8,942 as of December 31, 2017. For Mt Holland, exploration disbursements fall under Other Non-Current Non-Financial Assets and correspond to ThUS$11,298 as of December 31, 2018. As of December 31, 2017 there were no disbursements for this concept.

2. Economically feasible: Prospecting disbursements corresponding to caliche exploration, wherein the study concluded that its economic feasibility is viable, are classified under Non-Current Assets in Other Non-current Financial Assets. The balance as of December 31, 2018, is ThUS$5,099 and as of December 31, 2017, it is ThUS$12,530.

For the exploration of the Salar de Atacama, the associated assets correspond to wells that can be used both in monitoring and exploitation of the Salar. Therefore, once the studies are concluded, these are classified as Non-current Assets in Properties, Plants and Equipment, assigning them a technical useful life of 10 years.

3. Not economically feasible: Prospecting disbursements, once finalized and concluded to be not economically feasible, will be charged to profit and loss. As of December 31, 2018 and December 31, 2017, there is no existing disbursement for this item.

4. In Exploitation: Caliche exploration disbursements that are found in this area are amortized based on the material exploited. The portion that is exploited in the following 12 months is presented as current assets in the inventories. As of December 31, 2018, the amount is ThUS$2,028 and the balance as of December 31, 2017 for this concept is ThUS$521. The portion that will be amortized in the following years is classified as non-current assets under Other Non-current Assets. As of December 31, 2018, there is a balance of ThUS$9,791 for this concept, and as of December 31, 2017, the balance is ThUS$5,191.

Disbursements corresponding to metal exploration are charged to profit or loss in the period in which they are incurred.

## Note 28 Reportable segments

## 28.1 Reportable segments

## General information:

The amount of each item presented in each operating segment is equal to that reported to the highest authority that makes decisions regarding the operation, in order to decide on the allocation of resources to the defined segments and to assess its performance.

These operating segments mentioned are consistent with the way the Company is managed and how results will be reported by the Company. These segments reflect separate operating results that are regularly reviewed by the executive responsible for operational decisions in order to make decisions about the resources to be allocated to the segment and assess its performance (See Note 25.2).

The performance of each segment is measured based on net income and revenues.

## Factors used to identify segments on which a report should be presented:

The segments covered in the report are strategic business units that offer different products and services. These are managed separately because each business requires different technology and marketing strategies.

Description of the types of products and services from which each reportable segment obtains its income from ordinary activities

The operating segments, which obtain income from ordinary activities, generate expenses and have its operating results reviewed on a regular basis by the highest authority who makes decisions regarding operations, relate to the following groups of products:

1. Specialty plant nutrients

2. Iodine and its derivatives

3. Lithium and its derivatives

4. Industrial chemicals

5. Potassium

6. Other products and services

## Description of income sources for all the other segments

Information regarding assets, liabilities, profits and expenses that cannot be assigned to the segments indicated above, due to the nature of production processes, is included under the "Unallocated amounts" category of the disclosed information.



## Note 28 Reportable segments (continued)

## 28.1 Reportable segments, continued

## Basis of accounting for transactions between reportable segments

Description of the nature of the differences between measurements of results of reportable segments and the result of the entity before the expense or income tax expense of incomes and discontinued operations

The information reported in the segments is extracted from the Company’s consolidated financial statements and therefore there is no need to prepare reconciliations between the data mentioned above and those reported in the respective segments, according to what is stated in paragraph 28 of IFRS 8, "Operating Segments".

For the allocation of inventory valuation costs, we identify the direct expenses (can be directly allocated to products) and the common expenses (belong to coproduction processes, for example common leaching expenses for production of Iodine and Nitrates). Direct costs are directly allocated to the product and the common costs are distributed according to percentages that consider different variables in their determination, such as margins, rotation of inventories, revenue, production and etc.

The allocation of other common costs that are not included in the inventory valuation process, but go straight to the cost of sales, use similar criteria: the costs associated with a product or sales in particular are assigned to that particular product or sales, and the common costs associated with different products or business lines are allocated according to the sales.

Description of the nature of the differences between measurements of assets of reportable segments and the Company’s assets

Assets are not shown classified by segments, as this information is not readily available. Some of these assets are not separable by the type of activity by which they are affected since this information is not used by management in decision-making with respect to resources to be allocated to each defined segment. All assets are disclosed in the "unallocated amounts" category.

Description of the nature of the differences between measurements of liabilities of reportable segments and the Company’s liabilities

Liabilities are not shown classified by segments, as this information is not readily available. Some of these liabilities are not separable by the type of activity by which they are affected, since this information is not used by management in decision-making regarding resources to be allocated to each defined segment. All liabilities are disclosed in the "unallocated amounts" category.

Income tax is calculated based on the profit or loss for tax purposes that is applied to the effective tax rate applicable in Chile. As established by Law No.20,780, a progressive income tax rate has been established, which is 27% from 2018.

The royalty is determined by applying the taxable rate to the net operating income obtained. According to the chart in force, the Company currently provisioned 5% for mining royalties that involve operations in the Salar de Atacama and 5.64% for caliche extraction operations.

The income tax rate for the main countries where the Company operates is presented below:

## 32.3 Income tax and deferred taxes

Assets and liabilities recognized in the statement of financial position are offset if and only if:

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



## Note 32 Income tax and deferred taxes (continued)

## 32.3 Income tax and deferred taxes

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

(i) the same entity or tax subject; or

(ii) different entities or tax subjects who intend either to settle current fiscal assets and liabilities for their net amount, or to exercise tax 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.

Recognized deferred income tax assets are the income taxes that are to be recovered in future periods, related to:

a) deductible temporary differences.

b) the offsetting of losses obtained in prior periods and not yet subject to tax deduction; and

c) the offsetting of unused credits from prior periods.

The Company recognizes a deferred tax asset when there is certainty that these can be offset with tax income from subsequent periods, losses or fiscal credits not yet used, but solely as long as it is more likely than not that there will be tax earnings in the future against which to charge these losses or unused fiscal credits.

Recognized deferred tax liabilities refer to the amounts of income taxes payable in future periods related to taxable temporary differences.

## d.11) Explanation of the relationship between expense (income) for tax purposes and accounting income.

Based on IAS 12, paragraph 81, letter “c”, the company has estimated that the method that reveals the most significant information for users of the financial statements is the numeric conclusion between the tax expense (income) and the result of multiplying the accounting profit by the current rate in Chile. The aforementioned election is based on the fact that the main office and subsidiaries established in Chile generate a large part of the Company’s tax expense (income).

## d.12) Tax periods potentially subject to verification:

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



## Note 32 Income tax and deferred taxes (continued)

## 32.3 Income tax and deferred taxes, continued

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

## Chile

According to article 200 of Decree Law No 830, the taxes will be reviewed for any deficiencies in terms of payment and to generate any taxes that might arise. There is a 3-year prescriptive period for such review, dating from the expiration of the legal deadline when payment should have been made. This prescriptive period can be extended to 6 years for the revision of taxes subject to declaration, when such declaration has not been filed or has been presented with maliciously false information.

## United States

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

As a result of the audit performed by the tax authority, SQM North America Corp., a subsidiary of the Company, paid in November 2018, for income tax and interest between 2013 and 2015, approximately US$3.8 million. On top of this, SQM North America Corp would have to pay an additional US$0.4 million in state taxes for the same period. These charges are already provisioned in the financial statements.

## Mexico:

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

## Spain:

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

## Belgium:

In Belgium, the tax authority may review tax returns for up to 3 years 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 for a period of up to 5 years.

## South Africa:

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

## SOM BOARD PROTOCOL FOR THE PRESENTATION AND USE OF SENSITIVE INFORMATION

## 1. Background

(c) On August 27, 2018, Tianqi and the Chilean National Economic Prosecutor Office (the "FNE") signed an out-of-court settlement (the "Agreement"), pursuant to which the FNE sought to implement behavioral measures in order to (i) maintain the competitive conditions of the lithium market, (ii) mitigate the risks described in the Agreement and (iii) limit the possibility of accessing certain information related to the Company and its subsidiaries, which is defined as sensitive under the Agreement (the "Sensitive Information") by Tianqi (the "Purpose").

(d) The Antitrust Court (the "TDLC") approved the Agreement by resolution of October 4, 2018, which was finalized on October 30, 2018. In Agreement approval process, the Company expressed its concerns to the TDLC regarding the measures described in the Agreement as (i) not effectively resolving the risks that Tianqi and the FNE wanted to mitigate, (ii) not being correctly oriented to avoid the access to Sensitive Information that, could damage the Company and the correct functioning of the market when in the possession of a competitor, and (iii) contradicting Law 18,046 on Corporations (the "Corporations Act") and other regulatory bodies applicable to the Company.

The consolidated financial statements of Sociedad Química y Minera de Chile S.A. and Subsidiaries have been prepared in accordance with International Financial Reporting Standards (hereinafter “IFRS”) and represent the comprehensive, explicit and unreserved adoption of International Financial Reporting Standards as issued by the International Accounting Standard Board (IASB). Should there be any discrepancies between IFRS and the instructions issued by the Chilean Commission for the Financial Market (CMF) the latter shall prevail.

These consolidated financial statements fairly reflect the Company’s equity and financial position and the results of its operations, changes in the statement of income and expenses recognized and cash flows, which have occurred in the year then ended.

The valuation of the main assets and liabilities has been performed as follows:

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 the direct cost of materials and, when 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.

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

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.

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 a situation arises whereby the circumstances, which previously caused the rebate to cease 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.

The provisions for technical specification on the Company’s inventories have been made based on a technical study covering different variables affecting products in stock (density, moist, 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.

Property, plant and equipment: Tangible property, plant and equipment assets are stated at acquisition cost, net of the related accumulated depreciation and impairment losses that they have experienced.

## 1.2.1 Analysis by business area and market variances

## Lithium and Derivatives

Revenues from lithium and derivatives totaled US$734.8 million during the twelve months ended December 31, 2018, an increase of 14.0% compared to the US$644.6 million for the twelve months ended December 31, 2017.

Lithium and derivatives revenues increased 30.4% during the fourth quarter of 2018 compared to the fourth quarter of 2017. Total revenues amounted to US$233.9 million during the fourth quarter of 2018, compared to US$179.4 million in the fourth quarter of 2017.

The lithium market continued its strong growth in 2018, with total demand growth surpassing 27% according to our estimates. Demand growth was led by demand related to electric vehicles, we believe that full electric vehicle penetration rates reached 2% in 2018, and this number is expected to over double in the next five years. Demand in 2019 should be at least 20% greater than total demand in 2018.

Our average prices in 2018, increased over 25% compared to the previous year, and we were able to capture a significant price premium compared to many of our competitors during the same period. New supply is entering the market, which could impact our ability to maintain this price premium in 2019. However, there are several lithium grades of different qualities available in the lithium market, and not all products are sold at the same price; we do not believe that all lithium supply entering the market is suitable for all customers. We will focus on providing a high-quality lithium to our customers in 2019. We will also rebuild some inventories this year, and as a result of this, we believe our sales volumes in 2019 could be slightly higher to sales volumes seen in 2018.

Gross profit for the Lithium and Derivatives segment accounted for approximately 53% of SQM’s consolidated gross profit for the twelve months ended December 31, 2018.

## Specialty plant nutrition

Revenues from the SPN business line for the twelve months ended December 31, 2018 totaled US$781.8 million, an increase of 12.1% compared to $697.3 million reported for the twelve months ended December 31, 2017.

Fourth quarter 2018 revenues reached US$174.4 million, 6.2% lower than the US$185.9 million reported in the fourth quarter of 2017.

The potassium nitrate market remained strong this year, and we believe it grew approximately 6% in 2018. Sales volumes during 2018 for this business line increased 12% compared to 2017, due to demand growth and limited supply from our competitors. Sales volumes in the fourth quarter were lower than the third quarter as a result of seasonality and additional supply in the market. Average prices during 2018 remained flat compared to prices reported the previous year.

We believe that demand growth of potassium nitrate will be approximately 6% in 2019. SQM expects that new supply will continue to enter the market this year. As part of our ongoing strategy in the potassium nitrate market, we will continue to invest in this growing market.

SPN gross profit accounted for approximately 22% of SQM’s consolidated gross profit for the twelve months ended December 31, 2018.

## Iodine and derivatives



Revenues from sales of iodine and derivatives during the twelve months ended December 31, 2018 were US325.0 million, an increase of 28.9% compared to US252.1 million generated for the twelve months ended December 31, 2017.

Revenues from sales of iodine and derivatives for the fourth quarter of 2018 amounted to US81.9 million, an increase of 34.7% compared to US60.8 million achieved during the fourth quarter of 2017.

Higher iodine revenues in 2018 were the result of higher sales volumes and higher average prices. Our sales volumes in 2018 reached 13,300 MT, over 5% more than sales volumes reported in 2017, and setting a new company record. We closed the fourth quarter with average prices of almost US26/kg, exceeding our original expectations.

The iodine market grows consistently between 2-4% per year, and 2019 should be no different. As the largest player in this market, we believe it is important to plan for the future, meet the growing needs of our customers. For this reason, we submitted the environmental permit for an expansion of which will allow us to increase our capacity and meet future demand growth.

Gross profit for the Iodine and Derivatives segment accounted for approximately 14% of SQM’s consolidated gross profit for the twelve months ended December 31, 2018.

## Potassium: Potassium chloride and potassium sulfate

Potassium chloride and potassium sulfate revenues for 2018 totaled US267.4 million, a 29.5% decrease compared to the US379.3 million reported for the twelve months ended December 31, 2017.

Potassium chloride and potassium sulfate revenues decreased 39.2% in the fourth quarter of 2018, totaling US47.7 million compared to the US78.4 million reported for the fourth quarter of 2017.

Global demand in the potassium chloride market grew to approximately 66 million tons in 2018, growing about 3% when compared to last year. Prices in this market also increased during the year, and average prices in the business line increased 14% in 2018 compared to the previous year. Despite higher average prices, revenues in the potassium chloride and potassium sulfate business line decreased as anticipated, with sales volumes 38% lower during 2018 compared to 2017.

These lower sales volumes were a result of our production limitations as we focused our production efforts in the Salar de Atacama on increasing lithium yields. Furthermore, as a result of environmental compliance plan that was approved by the Chilean Environmental Authority (SMA) at the end of the year, we are temporarily extracting less brine than we had in the past. We had previously announced that potassium chloride and potassium sulfate sales volumes could decrease significantly in 2019 when compared to 2018, we now believe that sales volumes for 2019 will be below 500,000 MT.

Gross profit for Potassium Chloride and Potassium Sulfate business line accounted for approximately 6% of SQM’s consolidated gross profit for the twelve months ended December 31, 2018.

## Industrial chemicals

Industrial chemicals revenues for the twelve months ended December 31, 2018 reached US108.3 million, a 20.1% decrease compared to US135.6 million for the twelve months ended December 31, 2017.



Revenues for the fourth quarter of 2018 totaled US$13.7 million, a decrease of 74.9% compared to US$54.6 million for the fourth quarter of 2017.

In 2018, we sold approximately 47,000 MT of solar salts, we expect to sell a similar amount this year.

Gross profit for the Industrial Chemicals segment accounted for approximately 5% of SQM’s consolidated gross profit for the twelve months ended December 31, 2018.

## Other commodity fertilizers and other revenues

Revenues from sales of other commodity fertilizers and other income reached US$48.5 million in the twelve months ended December 31, 2018, the same as the US$48.5 million for the twelve months ended December 31, 2017.

(1) Assets = Total Assets – (Cash and cash equivalents + Financial Assets + Investments in related companies)



## 2.1 Analysis of Financial Indicators

## Liquidity:

- Current liquidity: the increase in the ratio can be explained because there was a decrease in Current Assets of US$66.5 million (2.7%), there was also a decrease in Current Liabilities of US$192 million (25.7%), resulting in a lower ratio value. The main variation of the Current Assets was seen in the decrease by US$74 million of Cash and Cash Equivalents, and in the decrease of US$54 million of Other Current Financial Assets, mainly due to a decrease in more than 90 days deposits and was partially offset by the increase in Current Tax Assets of US$24 million. On the liabilities side, the main change was seen in the Current Financial Liabilities, which decreased by US$192 million, mainly due to the payment and non-renewal of approximately US$160 million of bank loans that accrue interest and the decrease of US$30 million of hedge derivatives that covered the latter.

- Acid test: When comparing both periods, it can be noted that there was an increase in Inventory of US$12 million (1.3%), which, considering the aforementioned about Current Assets and Current Liabilities and taking this amount out of the equation, makes the gap between the items even greater, which results in a higher ratio than the previous one.

## Indebtedness:

- Debt ratio: this ratio increased, since, although the PC decreased by the US$192 million as mentioned above, Non-current Liabilities (NCL) increased by US$273 million (Total Liabilities are US$81 million, 4%), while Equity decreased by US$100 million (4.7%), thus proportionally decreasing the amount of Equity and resulting in a higher ratio. Within the NCL, the most outstanding movements were an increase of US$298 million in non-current financial liabilities, due to the inclusion of the series P bonds in UF equal of three million UF, series Q bonds of three million UF, a loan with Scotiabank of US$70 million, and a US$29 million decrease in deferred taxes. On the equity side, this decrease is mainly explained by the decrease in the accumulated profit of US$100 million.

- Proportional amount of debt: due to the aforementioned variations, where the reasons for the decrease in the Current Liabilities and the increase in the Non-Current Liabilities were explained respectively, it can be concluded directly that these ratios varied as they did.

## Activities:

- An increase in inventory turnover can be seen, mainly due to the fact that inventory increased by US$12 million (1.3%), while cost of sales (LTM) increased by US$88 million (6.4%), mainly due to higher sales volumes. Given the proportionally and quantitatively increase of cost of sales over the inventory, it can be concluded directly that the ratio increased as it did. Due to this increase, a decrease in inventory permanence of 11 days can also be seen, since both ratios are inversely proportional.

## Profitability:

- Earnings per share: recording the same number of shares, because of an increase in profit for the period by approximately US$13.6 million (3%), an increase in this ratio is generated. For further details, please, see the statement of income for the corresponding periods.



- ROE: The increase in this ratio was due to an increase in profit for the period and a decrease in equity of US$109 million.

- ROA: The decrease in this ratio was due to the fact that although the dividend of the equation increased by US$2.8 million (0.4%), the assets that influenced the equation increased by US$160 million (5.2%), thus generating the appreciation effect in the ratio.

## 3. Analysis of the Statement of Cash Flows

## 4. Market risk analysis

Interest rate: As of December 31, 2018, the Company’s financial liabilities, current and non-current that accrue interest amount to US$1,337.2 million and include the following types of financing:

i. Unsecured obligations bearing interest, current and non-current (considering principal owed only): a bond in U.S. dollars of US$300 million considering a fixed interest rate of 3.625%, a bond in U.S. dollars of US$250 million considering a fixed interest rate of 5.5%, a bond in U.S. dollars of US$250 million considering a fixed interest rate of 4.375%; a bond in UF for the amount equivalent to US$155.2 million at fixed rate in U.S. dollars, through a Cross Currency Swap, of 4.47%; and a bond in UF for the amount equivalent to MUS$134.2 at fixed rate in U.S. dollars, through a Cross Currency Swap, of 5.11%; and a bond in UF for the amount equivalent to MUS$119.0 at variable rate in U.S. dollars of UF+3.45.

ii. A loan in U.S. dollars of US$70 million at a fixed rate in U.S. dollars through an Interest Rate Swap of 3.72%.



As of December 31, 2018, the Company recorded US$23.6 million within other current financial liabilities and US$1,330.4 million within other non-current financial liabilities.

Exchange rate: SQM’s main economic environment operates in U.S. dollars. However, because of the Company’s internationalization, the Company operates in different countries which generate exposure to changes in exchange rates for the different currencies with respect to U.S. dollar. Accordingly, SQM has hedging contracts to mitigate the exposure generated by its main mismatches (assets net of liabilities) in currencies other than U.S. dollar against the variation in the exchange rate, updating such contracts on a weekly basis depending on the quantity of assets and liabilities necessary to hedge in currencies other than U.S. dollar.

To ensure the difference between its assets and liabilities, as of December 31, 2018, the Company had the following derivative contracts (as the sum of the absolute value of their notional values): US$108 million in Chilean peso/U.S. dollar derivative contracts, US$15.32 million in Euro/U.S. dollar derivative contracts, US$17.06 million in South African rand/U.S. dollar and US$27.73 in other currencies.

In addition, the Company had US$348.24 million in derivative contracts to hedge its investments in term deposits in Chilean pesos.

To hedge its expected net cash flows in Chilean pesos related to the businesses associated with the trading of fertilizers in Chile, the Company did not maintain any Chilean peso/U.S. dollar derivative contract as of December 31, 2018. To hedge its expected net cash flows in Euros the Company did not maintain any Euro/U.S. dollar derivative contracts as of December 31, 2018.

Commodity prices: The main commodities the Company uses are oil (petroleum) as fuel and in all its forms, Currently, the Company has no hedging contracts hedging international changes in prices, However, the Company has long-term contracts for energy supply.

As indicated in the Company’s Annual Report, markets in which the Company operates are unpredictable, exposed to significant fluctuations in supply and demand, and price high volatility. Additionally, the supply of certain fertilizers or chemicals, including certain products which the Company trades, vary mainly depending on the production of top producers and their related business strategies. Accordingly, the Company cannot forecast with certainty changes in demand, responses from competitors or fluctuations in the final price of its products. These factors can lead to significant impacts on the Company’s product sales volumes, financial position and share price.

Note 5 of the Consolidated Financial Statements as of December 31, 2018 includes a detailed analysis of risks associated with the Company’s businesses.
