The Gates Foundation has revealed it has back-up plans in case its co-chairs, Bill and Melinda Gates cannot work together in the wake of their divorce.
The new arrangement gives Bill and Melinda Gates a two-year trial, after which Ms Gates could resign from the organisation.
Bill and Melinda run the charitable foundation, which has worked on billion dollar initiatives such as fighting infectious diseases and this new agreement comes after question marks were raised over the future of the organisation when the couple announced they were divorcing after 27 years of marriage in May.
In a note to Gates Foundation staff on Tuesday, it was announced that the couple would be donating another $15bn (£10.9bn) of their personal wealth to the foundation.
Under the new agreement announced Wednesday, Ms Gates would also receive “personal resources” from her ex-husband for her own charity work.
Ms Gates said she was “deeply proud” of what the organisation has achieved.
In a statement, she added: “I believe deeply in the foundation’s mission and remain fully committed as co-chair to its work.”
