Under the oversight of the Board of Directors, SK D&D operates the Audit Committee, Compliance Officer, and compliance support organization (Legal Affairs Part), to ensure strict adherence to laws and regulations, thereby realizing corporate ethics and securing transparency and fairness in all business conduct.

The Audit Committee supports regulatory responses under commercial law as well as the company's accounting and financial audits, to strengthen the legality and validity of duties performed by directors and management. The Compliance Officer regularly checks the overall legal risks that may arise from management activities and business operations, and reports to the Board of Directors regarding compliance with control standards. The Legal Affairs Part, the supporting organization for the Compliance Officer, facilitates overall compliance work through internal process checks, and plays a role in managing business/investment-related risks, reviewing transactions between affiliates, and enhancing corporate governance.

SK D&D has established Internal Accounting Control Regulations and operates an Internal Accounting Control System to bolster the reliability of its financial statements by ensuring compliance with the laws related to financial information disclosure. We have appointed a full-time executive with expertise in accounting or internal control as our Internal Accounting Manager, who is responsible for designing and operating the internal accounting control system, checking its effectiveness, and reporting on it to the Board of Directors and the Audit Committee. The Audit Committee evaluates the operation of the internal accounting control system and reports its findings to the BOD, while the CEO oversees the system's management and operation, reporting the results to the General Meeting, the BOD, and the Audit Committee. Detailed regulations and operating outcomes are disclosed through our annual reports and internal accounting control system reports via DART (Data Analysis, Retrieval and Transfer System)—Korea’s electronic disclosure system for corporate filings—and the company website.

SK D&D has adopted and implements the Four Guidelines for Fair Transaction recommended by the Korea Fair Trade Commission to establish reasonable and fair transaction practices with its suppliers. The Four Guidelines for Fair Transaction include establishing and operating an internal screening committee, signing sound contracts, issuing and retaining documents, and selecting and operating a pool of business partners. Through the Legal Affairs Part, we strive to select and contract with business partners fairly in compliance with the four guidelines, and to prevent unfair transaction with business partners by voluntarily monitoring our own compliance with laws and regulations related to fair transaction.
