As provided in the Company’s by-laws, no shareholder can concentrate more than 32% of the Company’s voting right shares and therefore there is no controlling entity.
6.3 | Joint arrangements of controlling interest
Sociedad de Inversiones Pampa Calichera S.A., Potasios de Chile S.A., and Inversiones Global Mining (Chile) Ltda., collectively the Pampa Group, are the owners of a number of shares that as of December 31, 2017 are equivalent to 29.97 % of the current total amount of issued, subscribed and fully-paid shares in the Company. In addition, Kowa Company Ltd., Inversiones La Esperanza (Chile) Limitada, Kochi S.A. and La Esperanza Delaware Corporation, collectively the Kowa Group, are the owners of a number of shares equivalent to 2.12 % of the total amount of issued, subscribed and fully-paid shares of SQM S.A. The Pampa Group and the Kowa Group have informed SQM S.A., the Financial Markets Commission (formerly the Chilean SVS), and the relevant stock exchanges in Chile and abroad that they are not and have never been mutually related parties. This is independent of the fact that on December 21, 2006 the two Groups entered into a Joint Action Agreement (JAA) related to those shares. Consequently, neither the Pampa Group nor the Kowa Group individually owns more than 32% of the voting right capital of SQM S.A. This Joint Action Agreement has not transformed the Pampa and Kowa Groups into mutually related parties. The Joint Action Agreement has only transformed the current controller of SQM S.A., composed of the Pampa Group, and the Kowa Group, into related parties of SQM S.A. Detail of effective concentration
