LITIGATIONS a) Purchase and sales of raw materials agreement legal case On December 3, 2009, a company filed for arbitration against PTT Plc. (“PTT”) and the Company as a producer to perform according to purchase and sales of raw materials agreement, of which the said company has been committed by PTT, or to compensate for damages of approximately Baht 13,805 million. On March 8, 2010, the dispute was struck out of the case-list by the arbitration ruling that the Company was not a party to the contract. On August 27, 2010, the said company filed a civil suit to the Civil Court against PTT and the Company as a producer to perform according to purchase and sales of raw materials agreement, of which the said company has been committed by PTT, or to compensate for damages of approximately Baht 9,380 million. In this regards, the Company filed an objection against the indictment with the Civil Court on the basis that the Company was not a party to the contract. On May 21, 2013, the Civil Court considered that the arbitration process between such company and PTT has not yet been finalised; therefore, the Court has temporarily struck the case out of the case-list until the final decision has been reached under arbitration process. Then, both parties or either party can resubmit the case to the Civil Court for the further trial. Subsequently, on March 25, 2016, the arbitration has reached a conclusion for PTT to compensate the damages in some amount. On June 30, 2016, PTT submitted a motion for setting aside the arbitral award to the Civil Court. Thereafter, on September 19, 2019, the Civil Court rendered the judgement for enforcement of the arbitral award. PTT has appealed against the Civil Court’s judgement to the Supreme Court and the Supreme Court rendered the judgement for enforcement of the arbitral award. This case has become final and the Company has no any liability to compensate for any damage. 341 BUSINESS OPERATION AND PERFORMANCE CORPORATE GOVERNANCE FINANCIAL REPORTS AND FINANCIAL STATEMENTS APPENDIX
