Facebook chief executive Mark Zuckerberg and his wife, Priscilla Chan, have said they will donate 99 per cent of their shares in the social network to charity.
In a note released late Tuesday, Zuckerberg and Chan said the donation, made through the Chan Zuckerberg Initiative, would be made to ensure their daughter, Max, can live in a better world. The two objectives, they said, were to tackle advancing human potential and promoting equality.
Zuckerberg and Chan said long term investment was necessary to tackle these issues, and technology would be needed to help.
The donation would be over the course of both their live spans. Zuckerberg said the value of the contribution was $45 billion (£29.9 billion). Zuckerberg and Chan said further details would be shared once they both returned from current paternity and maternity leave.
