Introduction to our Whistleblower System (“the System”)

Outline of the System

- The system is designed to prevent financial incidents and minimize any losses and damages that we may incur due to an incident by encouraging employees to report other employees’ illegal acts, unjust ways of handling business, and acts judged to be evidence or signs of an incident. (Relevant in-house regulations: Guidelines for the Operation of the Whistleblower System [“the Guidelines”])

Eligibility of whistleblowers

- All employees of a member business of Woori Financial Group (including contract/temporary/dispatched employees).

Acts/matters subject to whistleblowing

- Any matter judged to fall foul of the Internal Control Criteria - Accounting processing that violates the internal accounting control system stipulated in the 「Act on the External Audit of Stock Companies」, Article 28. - Acts suspected to violate the 「Act on Real Name Financial Transactions and Confidentiality」or the 「Act on the Reporting and Using Specified Financial Transaction Information and the Utilization Thereof, etc.」. - Acts suspected to be a crime, such as embezzlement, professional negligence, theft, intimidation, acceptance of bribery, introduction to a private loan, unjust acts related to savings, flight of domestic property, etc. - Issuance of illegal/unjust orders to a subordinate. - Sexual harassment. - Acts feared to cause serious damage to the Group’s prestige, including social disturbance. - Acts judged to violate the 「Improper Solicitation and Graft 」. - Acts judged to be dishonest requests for hiring or the like (including attempts to engage in or influence a dishonest hiring process through a third party). - Other acts judged to be illegal/unjust ways of handling business or a sign of an incident.

Methods of whistleblowing (※ A whistleblower may use his/her real name or a pseudonym)

Protection of whistleblower’s identity and confidentiality

- The contents of whistleblowing shall be kept confidential under the Guidelines and handled only by a small number of relevant employees. (The employees concerned shall submit a confidentiality affidavit and handle cases of whistleblowing fairly and independently.)

Protection of whistleblowers

- It is prohibited to put whistleblowers at a disadvantage, such as unfavorable working conditions. - Remedial action may be requested if a whistleblower is judged to have been put at a disadvantage. - A change of a whistleblower’s place of work may be requested if necessary. - Persons who cooperate with a whistleblowing-related investigation will be afforded protection similar to that offered to a whistleblower.

※ A violator of the confidentiality obligation or the obligation of whistleblower protection will be subject to punishment under the Guidelines.

※ A whistleblower may be liable to punishment if he/she is found to have blown the whistle with deliberate intent to damage an individual’s reputation or for other self-interested purposes, or if the whistleblower is found to have made false accusations or statements.

※ Incentives (e.g. commendation or reward money) will be presented to a whistleblower who contributes to preventing losses and/or damages to the Company.
