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 Comercial 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 and its subsidiaries have 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.
21.2 Restrictions to management or financial limits Contracts that subscribed the issuance of bonds 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: Maintain a borrowing ratio less than 1.44 for the Series H bond and Series O bond. Furthermore, both bonds establish that if the borrowing ratio (as this term is defined in the respective issuance contracts) exceeds 1.2, (provided that this does not exceed than 1.44 times), the bondholders can voluntarily and individually choose to redeem these bonds early at par value. The indebtedness ratio as of December 31, 2019 reached a proportion of 1.19. As of December 31, 2019, the above-mentioned financial indicator has the following values:
Indicator |  | As of December ‎ 31, 2019 |  |  | As of December ‎ 31, 2018 |
Leverage |  |  | 1.19 |  |  |  | 1.00 |
Bond issue agreements issued abroad require the Company to neither merge nor dispose of the whole or a substantial part of its assets, unless all the following conditions are met: (i) the legal successor company is an entity subject to either Chilean or United States law, and assumes SQM S.A.’s obligations under a complimentary contract, (ii) the Issuer does not fail to comply immediately after the merger or disposal, and (iii) the Issuer delivers a legal opinion stating that the merger or disposal and the complimentary contract meet the requirements described in the original contract. 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 . 21.3 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. The SMA approved SQM’s proposed compliance program in its resolution dated January 26, 2019, and this program is currently being executed. On March 22, 2019, the indigenous communities of Quillagua and Huatacondo filed a complaint against the resolution that approved the compliance program before the First Environmental Court of Antofagasta (R-21-2019). This process was suspended on May 16, 2019. The SMA issued a resolution dated November 28, 2016, rectified by a resolution dated December 23, 2016, which filed charges against SQM Salar for brine extraction in excess of authorized amounts, progressive impairment of the vitality of carob trees, providing incomplete information, amending variables, and other charges. SQM Salar S.A. presented a compliance program that was accepted by the SMA. On December 26, 2019, the Environmental Court of Antofagasta rendered null and void the SMA ruling that approved the program and the SMA and SQM Salar presented motions for cassation against this verdict. These were accepted for processing and submitted to the Supreme Court and are currently pending final ruling. Although the ruling approving the compliance program has been rendered null and void, SQM Salar continues to comply with the measures it agreed to under this program. Once the Supreme Court resolves these issues, approval of the compliance program may be confirmed, a new program may be presented that considers other measures in agreement with the SMA or the sanctions process may be reinstated. This latter event may consider the application of fines up to US$9 million, temporary or permanent closure of facilities and in extreme circumstances, revocation of the respective environmental permit. 21.4 Tax Contingencies On August 26, 2016, SQM Salar filed a tax claim before the Third Tax and Customs Court of the Metropolitan Region against settlements 169, 170, 171 and 172, which extend the application of specific mining tax to lithium exploitation. The disputed amount is approximately US$17.8 million. On November 28, 2018, the Third Tax and Customs Court rejected the claim, and the case was transferred to the Santiago Court of Appeals, following an 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 current taxes receivable and non-current taxes receivable as of December 31, 2019 and 2018. The amount in dispute is US$ 32.2 million, and approximately US$ 25.2 million of this sum is the potential specific mining tax associated with lithium, whereas US$7.0 million is an excess charge by the SII regarding this latter value, the internal revenue service (SII) has acknowledged the excessive charge of US$5.8 million, and a request has been made on October 17, 2019 for it to be returned , The difference of US$ 1.2 million for the lower first category tax rate plus interests and fines will be reinstated at the end of the trial . The SII has not settled differences with respect to specific mining taxes for 2016, 2017, 2018 and 2019. the current business year. As of the date of these financial statements, the Company has not made provisions for these potential 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, 2018 y 2019 financial years, It is reasonable to expect that should these assessments for the period 2016 through the fourth quarter of 2019 be issued, the value would be approximately US$ 69 million (without considering potential interest and fines). The Company continues to undertake all legal efforts to actively and decidedly defend its interests . 21.5 Co ntingencies regarding the Changes to the Contracts with Corfo : On September 6, 2018, representatives Claudia Nathalie Mix Jiménez, Gael Fernanda Yeomans Araya and Camila Ruslay Rojas Valderrama and the Poder Ciudadano political party filed an annulment suit against Corfo, which requested that the Contract for the Salar de Atacama Project between Corfo and the Companies be annulled. The Companies have taken part of the process as interested third parties. In the event that the annulment claim is approved for the Salar de Atacama Project Contract, SQM Salar may be prevented from exploit the mining claims in the Salar de Atacama that it has leased from Corfo. 21.6 Contingencies related to the Class Action lawsuit Since October 2015, a consolidated class action lawsuit has been pending against the Company before the District Court for the Southern District of New York of the United States. The consolidated lawsuit alleges that certain statements made by the Company between June 30, 2010, and June 18, 2015, mainly in documents filed with the SEC and in Company press releases, were materially false and this constitutes a violation of Section 10 (b) of the Securities Exchange Act and of the correlative Standard 10b-5. Specifically, the consolidated lawsuit challenges certain statements issued by the Company associated with its compliance with or implementation of the laws and regulations that regulate it, the effectiveness of its internal controls, the adoption of a code of ethics consistent with SEC requirements, of its income or revenue and taxes paid, and of the applicable accounting standards. The primary plaintiff seeks compensation for the class in a yet undetermined amount for economic losses occurring as a result of the questioned statements. On January 10, 2018, the primary plaintiff filed a motion to certify a class composed of all people or entities who purchased ADSs in the Company between June 30, 2010, and March 18, 2015, and this motion is still pending with the court. Although the Company expects to actively and decisively defend its position, the outcome of this litigation cannot be predicted. 21.7 Restricted or pledged cash The subsidiary Isapre Norte Grande Ltda., in compliance with the provisions established by the Chilean Superintendence of Healthcare, which regulates the running of pension-related health institutions, maintains a guarantee in financial instruments delivered in deposits, custody and administration to Banco de Chile.
