One part of the survey has provided the opportunity to the employees to vote on the mascot to represent the corporate governance of the company and code of business conduct to reach the same goal with integrity, transparency and competitiveness.

This is the original concept to design this Good Corporate Governance Handbook or code of business conduct to reach the same goal with integrity, transparency and competitiveness.
