(1) | Payment Obligations for the lease contract with Corfo: These correspond to obligations assumed in the Lease Agreement. 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. On January 17, 2018, SQM and Corfo reached an agreement to end an arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce and other cases related to it.
The agreement signed in January 2018, includes important amendments to the lease agreement and project agreement signed between Corfo and SQM in 1993. The main modifications became effective on April 10, 2018 and requires an increase in the lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. This agreement has been amended since it was signed, and it is reasonable to expect that it will continue to be amended as mutually agreed by the parties. Additionally, SQM Salar commits to contribute to research and development efforts, as well as to the communities in close proximity to the Salar de Atacama and provide a percentage of total annual sales of SQM Salar to regional development. SQM Salar commits to contribute between US$10.8 million and US$18.9 million per year to research and development efforts, between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and 1.7% of total annual sales of SQM Salar to regional development. 18.3 Changes in provisions ​
