ttb has set up a Whistleblower Policy and Procedure approved by the Board of Directors as a channel for a person to inform the Bank of violations of laws and regulations, misconduct and unethical behaviors, frauds committed by employees or external parties that may have impact on the interests of the Bank, either financially or non financially.

The purpose of the Policy is to promote good corporate governance, high standards of ethical conduct as well as integrity and reputation of the Bank. ttb encourages employees, to bring to the notice of the Bank any honest and factual issue involving compromise or violation of ethical norms, legal or regulatory provisions.

ttb will not discharge, demote, suspend, threaten, harass, or in any other matter discriminate against an employee in the terms and conditions of employment because of any lawful or other actions done by the employee with respect to good faith, honest and factual reporting of complaints or participation in a related investigation.

ttb also encourages customers, shareholders, vendors and business partners to report similar incidents to the Bank.

The person making the report should give clear statement of the issue as well as name of reporting person, the place and date of occurrence, telephone number or email address for contacting so that the Whistleblower Reporting Officer can respond back on progress of the investigation or in case additional information is needed. ttb will maintain the confidentiality of the complaint or anonymity of the person making the complaint to the fullest extent reasonably practicable within the legitimate needs of law. However, reports may be submitted on an anonymous basis but they may not facilitate follow–up and responses on progress of the case.
