Our Board of Directors is proposing an unchanged dividend for shareholders of CHF 2.75 per share for 2019. The proposal represents a payout of 30.7% of 2019 reported net profit. Subject to approval at the upcoming Annual General Meeting (AGM) on 28 April 2020, 50% of the dividend of CHF 2.75 per share for 2019 will be paid out of the capital contribution reserve and will therefore be free from Swiss withholding tax.
