Tax implications of the dividend

Shareholders are advised that the dividend declared will be paid out of income reserves and may therefore be subject to dividend withholding tax depending on the tax residency of the shareholder.

South African tax residents

South African shareholders are advised that the dividend constitutes a foreign dividend. For individual South African tax resident shareholders, dividend withholding tax of 20% will be applied to the gross dividend of 24.8148 South African cents per share.

Shareholders who are South African tax resident companies are exempt from dividend tax and will receive the dividend of 24.8148 South African cents per share. This does not constitute legal or tax advice and is based on taxation law and practice in South Africa. Shareholders should consult their brokers, financial and/or tax advisors with regard to how they will be impacted by the payment of the dividend.
