Item 4.

Purpose of Transaction

 

The Reporting Persons undertook the purchases and sales of Series B Shares listed above in Item 3 in order to increase their interest in SQM and for investment purposes.

Pampa purchased the Series B Shares on July 3, 2006 in order to increase Mr. Ponce Lerou’s indirect combined ownership in SQM to over 25% for investment purposes so that he would be deemed, solely for purposes of Chilean law, as a “controlling shareholder” under Articles No. 97 and No. 99 of the Chilean Securities Act. The acquisition by Pampa of the Series B Shares, however, did not materially affect the Reporting Persons’ control rights over SQM since the Series B Shares have limited voting rights (holders of Series B Shares elect one of eight members of the Board of Directors (the “Series B Director”) and vote together with the Series A Shares on other matters).  Although being deemed as a “controlling shareholder” for purposes of Chilean law does not provide additional control rights, it does result, under Chilean corporate law, in the “controlling shareholder” not being required to extend a mandatory public tender offer upon subsequent purchases of securities of the Company.

Pampa purchased additional Series B Shares for investment purposes on the open market on various dates ranging from November 8, 2006 to December 20, 2006, and on December 22, 2006, entered into the Kowa Shareholders Agreement, as described in Item 6 hereof, in order to maintain Mr. Ponce Lerou’s position of “controlling shareholder” under Articles No. 97 and No. 99 of the Chilean Securities Act.  For the reasons described in the preceding paragraph, these transactions did not materially affect the Reporting Persons’ control rights over SQM.    

The June 1, 2007, June 4, 2007 and July 26, 2007 sales of Series B Shares by Pampa on the open market were for investment purposes. The open market acquisitions of Series B Shares by Pampa from August 24, 2007 to September 4, 2007, as well as the open market sales of Series B Shares by Pampa from October 12, 2007 to October 23, 2007 were also for investment purposes.

The open market sales from March 28, 2008 to April 9, 2008 of Series B Shares by Pampa were for investment purposes.  The May 22, 2009 purchase of Series B Shares by Pampa was for investment purposes. The open market purchases from October 28, 2009 to December 21, 2009 of Series B Shares by Pampa were for investment purposes.

The September 13, 2010, September 23, 2010 and September 30, 2010 open market purchases by Pampa of Series B Shares were for investment purposes. The open market purchases from October 6, 2010 to January 3, 2011 by Norte of Series B Shares were for investment purposes.

The January 5, 2011 open market purchase of Series B Shares by Pampa was for investment purposes. The January 25, 2011 and January 26, 2011 open market sale by Norte of Series B Shares were for investment purposes. The February 9, 2011 and March 4, 2011 open market purchases by Pampa of Series B Shares were for investment purposes. The open market sales from April 26, 2013 to May 17, 2013 by Pampa of Series B Shares were for investment purposes. The open market sales from July 9, 2013 to August 5, 2013 by Pampa of Series B Shares were for investment purposes. The December 9, 2013 and December 10, 2013 open market sales by Pampa of Series B Shares were for investment purposes.

The open market purchases from March 2, 2015 to April 9, 2015 by Pampa of Series B Shares were for investment purposes. The March 20, 2015 open market sale of Series B Shares by Pampa was for investment purposes.

Each of the Reporting Persons intends to review its investment in SQM on a regular basis and, as a result thereof, may at any time or from time to time determine, either alone or as part of a group, (a) to acquire additional securities of SQM, through open market purchases, privately negotiated transactions or otherwise, (b) to dispose of all or a portion of the securities of SQM owned by it in the open market, in privately negotiated transactions, in one or more registered public offerings or otherwise, or (c) to take any other available course of action, which could involve one or more of the types of transactions or have one or more of the results described in the next paragraph of this Item 4. For example, on April 20, 2018 the Reporting Persons proposed an amendment to the bylaws of SQM that would affect the Company’s corporate governance.  Notwithstanding anything contained herein, each of the Reporting Persons specifically reserves the right to change its intention with respect to any or all of such matters. In reaching any decision as to its course of action (as well as to the specific elements thereof), each of the Reporting Persons currently expects that it would take into consideration a variety of factors, including, but not limited to, the following: SQM’s business and prospects; other developments concerning SQM and its businesses generally; other business opportunities available to the Reporting Persons; changes in law and government regulations; general economic conditions; and financial and stock market conditions, including the market price of the Series B Shares.

Except as set forth in this Item 4, the Reporting Persons have no present plans or proposals that relate to, or that would result in, any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act.

Contracts, Arrangements, Understandings or Relationship with Respect to Securities of the Issuer

 

(a)

Shareholders Agreements

In order to set the terms and conditions governing their joint ownership of SQYA, Inversiones SQ Holding S.A. (“SQ Holding”) (predecessor entity of SQ) and Norsk Hydro Holland B.V. (“Norsk”) entered into the Shareholders Agreement of Inversiones SQNH S.A. (predecessor entity of SQYA) dated April 18, 2002 (the “Yara Shareholders Agreement”). Pursuant to the Yara Shareholders Agreement, SQ Holding and Norsk agreed that Norsk, as the then-owner of 49% of the share capital of SQYA, had the right to designate at least one person to be elected to the boards of directors of Norte, Oro, Pampa and SQM. SQ Holding and Norsk further agreed that any of their votes remaining after electing a person designated by Norsk to the boards of Norte, Oro, Pampa and SQM would be used to elect three directors designated by SQ Holding to the boards of Norte, Oro and Pampa and two directors designated by SQ Holding to the board of SQM. Under the Yara Shareholders Agreement, SQ Holding and Norsk further agreed that the president of SQM would always be designated by SQ Holding.

On September 15, 2004, Yara acquired Norsk’s interest in SQYA and assumed all of Norsk’s rights and obligations under the Yara Shareholders Agreement. On November 9, 2005, the shareholders of SQ Holding resolved to split SQ Holding into two companies, SQ Holding (surviving entity) and SQ (newly formed entity). SQ Holding’s 51% stake in SQYA was transferred to SQ.

 On April 21, 2008, SQ and SQH S.A., both controlled by Mr. Julio Ponce Lerou, acquired from Yara Netherland B.V. the 49% shares of SQYA owned by Yara. Accordingly, Mr. Julio Ponce Lerou obtained indirect controlling interest of 100% of the shares of SQYA. As a result, as of April 21, 2008 the Yara Shareholders Agreement has been terminated and Yara is no longer a related company of SQM.

On December 21, 2006, Pampa and Kowa entered into a shareholders agreement (the “Kowa Shareholders Agreement”) which provides, among other things, that each party will vote its shares in SQM together on significant matters.  In addition, under the Kowa Shareholders Agreement Pampa granted Kowa tag-along rights with respect to certain sales of its SQM shares. The Kowa Shareholders Agreement was amended on April 3, 2008 to allow each of Pampa and Kowa to be able to vote their respective shares in their discretion in connection with the election of the members of the board of directors of SQM (the “First Amendment to the Kowa Shareholders Agreement”). A copy of the First Amendment to the Kowa Shareholders Agreement was attached as Exhibit 4 to Amendment No. 5 filed on June 7, 2017. On March 17, 2009, Pampa and Kowa informed the SVS that they had agreed to disregard the provisions contained in the last two sentences of the final paragraph of clause 2.03 of the Kowa Shareholders Agreement. As part of the Corporate Governance Agreement (as defined below), Pampa, Potasios and Global Mining agreed to terminate the Kowa Shareholders Agreement within thirty (30) days of the effectiveness of the Corporate Governance Agreement. As a result, on April 16, 2018, Pampa, Potasios and Global Mining sent the requisite written notice to Kowa pursuant to the Kowa Shareholders Agreement terminating the agreement. Pampa, Potasios, Global Mining and Kowa agreed that the termination of the Kowa Shareholders Agreement is effective as of April 30, 2018.

On April 17, 2017, Pampa, Potasios and Global Mining (the “Cascadas Shareholders”), Kowa, La Esperanza (Chile), Kochi and La Esperanza Delaware (the “Kowa Shareholders”), and Inversiones el Boldo Limitada, Inversiones RAC Chile Limitada and Inversiones PCS Chile Limitada (the “PCS Shareholders”), signed a letter agreement (the “Letter Agreement”) with respect to certain corporate governance matters of SQM. Pursuant to the Letter Agreement, in the event that any member of the Board of Directors of SQM (the “Board”) elected by the Class A shareholders ceases to serve as such for any reason each of the parties will take all actions available to it to cause the Board to elect his or her successor (or any future successor that is nominated by another Board member) in accordance with the recommendation of the same party that elected the Board member that ceased to be a member. In addition, in the event that the member of the Board elected by the Class B shareholders ceases to serve as such for any reason, (a) none of the Cascadas Shareholders nor the Kowa Shareholders will vote any SQM shares or take any other action that affects the election of his successor or any future successor (the “Class B Successor”) and (b) each of the Cascadas Shareholders and the Kowa Shareholders will take all actions available to it to ensure that the Board does not approve any Class B Successor whose election was not approved by majority vote of the Class B shares (excluding any shares beneficially owned by any Cascadas Shareholders or Kowa Shareholders or as to which any Cascadas Shareholders or Kowa Shareholders has a proxy or exercises any voting control) or by the PCS Shareholders, as the case may be. In addition, for the term of the Board elected at the 2017 annual shareholders meeting, the Cascadas Shareholders, the Kowa Shareholders and the PCS Shareholders agreed that they will take all action available to them so that (1) no matter is approved by the Board unless it is affirmatively approved by at least five of the eight members of the Board and (2) the Chairman of the Board does not exercise a casting vote under the by-laws if there is a tie. The parties also agreed to support a dividend policy as set forth in Exhibit A to the Letter Agreement. The Letter Agreement was attached as Exhibit 8 to Amendment No. 5 filed on June 7, 2017.

On December 18, 2017, the Cascadas Shareholders entered into an agreement in relation to the corporate governance of SQM (the “Corporate Governance Agreement”) in their respective capacities as shareholders of the Company to both strengthen the corporate governance of the Company by creating certain binding obligations and because they were interested in the development of the pending arbitration proceedings between SQM and certain of its subsidiaries and the Chilean Production Development Corporation (Corporación de Fomento de la Producción de Chile) (“CORFO”) (such an agreement had been requested by CORFO).  Pursuant to the Corporate Governance Agreement, the Cascadas Shareholders unilaterally and irrevocably agreed in favor of CORFO to undertake certain measures with the aim of reaching a comprehensive solution for the corporate interest of the Company and all of its shareholders and that allows Chile to position itself in a strategic position in the lithium and electric vehicle market in general, including:

(a)

appointing and maintaining the appointment of, with the Series A Shares that they respectively own, at least one (1) independent director on the Board in accordance to the terms set forth in Article No. 50 bis of the Chilean Corporations Act;

(b)

causing that the following matters are only approved by an absolute majority of the Board (i.e. the chairman shall not cast the deciding vote) when such matters must be resolved by the Board: (i) making donations or any other gratuitous act or contract, (ii) entering into transactions with parties related to the Cascadas Shareholders, and (iii) initiating any type of jurisdictional action with respect to CORFO or the State of Chile (provided, in the latter case, such action is related to any instrument, agreement, or convention in which CORFO is a party or has an interest in), and this shall not cover any counterclaims that SQM may have in actions previously brought by CORFO or the State of Chile against SQM;

(c)

voting at any shareholders meeting of SQM, with the Series B Shares that they respectively own, for an independent director in accordance to the terms set forth in Article No. 50 bis of the Chilean Corporations Act, who is proposed as an independent director for the Series B Shares, provided that at least one candidate is proposed as such. The Cascadas Shareholders also undertook not to appoint or vote as director for the Series B Shares any person related to the Cascadas Shareholders;

(d)

not nominating or voting Mr. Ponce Lerou or any relative up to and including the second degree of consanguinity, as a director of the Company or SQM Salar S.A. (“SQMS”) and causing that the directors of SQM and SQMS may not nominate or vote any of the same as executives or management of SQM and SQMS, respectively;

(e)

terminating the Kowa Shareholders Agreement within thirty (30) days of the effectiveness of the Corporate Governance Agreement;

(f)

not terminating the Letter Agreement, unless (i) the PCS Shareholders lose the ability to appoint at least three (3) directors of the Board elected with the Company’s Series A Shares or (ii) the Kowa Shareholders lose the ability to appoint at least one (1) director of the Board elected with the Company’s Series A Shares;

(g)

causing the directors of the Board appointed with the Company’s Series A Shares owned by the Cascadas Shareholders, to vote for the independent director referred to in clause (a) above to be the chairman of the Board;

(h)

agreeing not to enter into any joint participation agreement with any third parties that would allow them to become the sole controller or joint controller of the Company, as such terms are defined in Article No. 97 of the Chilean Securities Act; and

(i)

agreeing not to enter into any commercial or joint participation  agreement with any person other than the Company, that extracts brines with lithium content on mining properties owned by CORFO and located in the Salar de Atacama, Chile.

The obligations set forth in clauses (a), (b), (c), (d), (h) and (i) shall expire on December 31, 2030; the obligations set forth in clause (f) shall expire on December 31, 2020 and the obligations set forth in clause (g) shall expire on March 31, 2022.

The effectiveness of the Corporate Governance Agreement is subject to a number of conditions precedent, namely (a) the approval by CORFO within one hundred twenty (120) calendar days from December 18, 2017, (b) the amendment of certain lease agreements of certain mining properties located in the Salar de Atacama, Chile, between CORFO and the Company (and certain Company’s subsidiaries) and (c) that the aforementioned instruments between CORFO and the Company (and certain of the Company’s subsidiaries) obtain all required approvals to be enforceable and fully executable under Chilean law, including the prior approval of certain Chilean regulatory agencies. On April 16, 2018, CORFO informed the Cascadas Shareholders that all of these conditions precedents had been satisfied.

The Corporate Governance Agreement provides that all of the obligations provided therein shall become void, ipso facto, and shall not bind the Cascadas Shareholders or give any rights to CORFO (except in the case of (h) above) in the event that the Cascadas Shareholders and Mr. Ponce Lerou (including their related parties) no longer have the ability to appoint at least three (3) directors to SQM’s Board of Directors to be appointed with the Series A Shares of SQM. The Corporate Governance Agreement also provides that all of the obligations provided therein shall become void, ipso facto, and shall not bind the Cascadas Shareholders or give any rights to CORFO in the event that Mr. Ponce Lerou (himself or through other legal entities) definitively and absolutely ceases to be a controller or co-controller of Pampa, Global Mining or Potasios, in accordance with Article No. 97 of the Chilean Securities Act. The obligations set forth in the Corporate Governance Agreement will not affect any shares of SQM owned by the Cascadas Shareholders in the event that they are sold and acquired by an unrelated third party.

The Corporate Governance Agreement further provides that the business and affairs of the Company shall be handled by its administration under the direction of the Board, and not by the parties to the Corporate Governance Agreement, and none of the provisions of the Corporate Governance Agreement shall limit the powers or authority of the Board or the administration of the Company, nor shall the Corporate Governance Agreement give any of the parties thereto the right or power to direct the Board or the administration of the Company to undertake or refrain from undertaking any type of action.  The Corporate Governance Agreement is governed by the laws of the Republic of Chile.

The foregoing summary fairly and accurately summarizes and describes (i) the terms of each material provision of the Corporate Governance Agreement and (ii) the terms that have been omitted or abridged.  Both the original Spanish-language Corporate Governance Agreement and an unofficial English translation are available on the Company’s website at http://www.sqm.com.

Pledge Agreements relating to the Senior Notes

On February 14, 2007, Pampa entered into a Share Pledge Agreement under Chilean law with Deutsche Bank Trust Company Americas (the “Trustee”) in connection with the February 17, 2007 issuance of US$250,000,000 7.75% Senior Secured Notes due 2022 (the “Senior Notes”) (as amended, the “Pledge Agreement”).  Pursuant to the Pledge Agreement, Pampa pledged to the Trustee, acting on behalf of the holders of the Senior Notes, a certain number of Series A Shares and Series B Shares to be held as collateral for the Senior Notes (the “Pledged Shares”). The Pledge Agreement grants the Trustee a first priority lien on such Pledged Shares. The Pledge Agreement contains a provision whereby the total amount of Pledged Shares is adjusted depending upon the fluctuations of the “Notes Collateralization Ratio.” The Notes Collateralization Ratio is a fraction: the numerator is the Fair Market Value (as defined in the Indenture) of the Pledged Shares on the Chilean Stock Exchange and the denominator is the total principal amount of the Senior Notes outstanding.

On December 4, 2008, Pampa entered into the First Supplemental Indenture and amended the Pledge Agreement in order to (i) increase the Fair Market Value of Series A or Series B shares of SQM required to be pledged to the Trustee from 2.0 times to 3.0 times of the total principal amount of Senior Notes outstanding, and (ii) change the ratios at which Series A or Series B shares were required to be pledged to the Trustee or may be released according to changes in Fair Market Value. A copy of the First Supplemental Indenture was attached as Exhibit 6 to Amendment No. 5 filed on June 7, 2017.

On August 22, 2012, Pampa entered into the Second Supplemental Indenture and amended the Pledge Agreement in order to revise the mechanism for triggering the obligation of Pampa to pledge additional SQM shares (the “Additional Pledge Agreements”) to maintain a collateralization ratio of at least 3.0 (the “Minimum Collateralization Ratio”) if the Notes Collateralization Ratio remains below the Minimum Collateralization Ratio during a predefined period of time, as follows: (i) if the Notes Collateralization Ratio remains below the Minimum Collateralization Ratio of 3.0 but above the Notes Collateralization Ratio of 2.7 for a period of 60 consecutive days, Pampa will be required to pledge additional SQM Shares up to the Minimum Collateralization Ratio of 3.0 within 10 business days after becoming aware of such event, and (ii) if at any point in time the Notes Collateralization Ratio falls below 2.7, Pampa will be required to pledge additional SQM shares up to the Minimum Collateralization Ratio of 3.0 within 3 business days after becoming aware of such event. In addition, the Second Supplemental Indenture provides that Pampa must own and maintain, at all times, sufficient Series A or Series B Shares with a Fair Market Value of not less than US$100 million, free and clear of any Lien (as defined in the Indenture) and reserved for Pampa to pledge to the Trustee pursuant to the Share Pledge Agreement. A copy of the Second Supplemental Indenture was attached as Exhibit 7 to Amendment No. 5 filed on June 7, 2017.

As of the date of this Statement, the aggregate amount of Series A Shares pledged by Pampa under the Pledge Agreement and the Additional Pledge Agreements is 15,556,362 and there are no Series B Shares pledged under the Pledge Agreement and the Additional Pledge Agreements.
