Key areas addressed in the amendments include the introduction of the capital band to provide enhanced financial flexibility, the incorporation of provisions for the use of electronic means for improved shareholder participation and general revisions to ensure adherence to the new law. Additionally, voluntary adjustments have been made to further consolidate the governance structure. The Board of Directors believes that these amendments will reinforce the governance framework and demonstrate the commitment to the highest standards of corporate conduct.
