master franchise agreement to run 145 McDonald's restaurants in South Africa. He also belonged to the Coca-Cola Company International Advisory Board and the Unilever Africa Advisory Council. Ramaphosa's various shareholdings made him one of South Africa's richest men. According to the Sunday Times, his estimated net worth of R2.22 billion made him the 13th richest person in South Africa in 2011, and that figure jumped to R3.1 billion in 2012. Both estimates, moreover, excluded his unlisted investments through Shanduka, including the McDonald's franchise agreement and a coal-mining partnership with Glencore. Cattle farming During a visit to Uganda in 2004, Ramaphosa became interested in the Ankole breed of cattle. Because of inadequate disease control measures in Uganda, the South African government denied him permission to import any of the breed. Instead, Ramaphosa purchased 43 cows from Ugandan president Yoweri Museveni and shipped them to Kenya, where they were artificially inseminated; the embryos were then removed and shipped to South Africa, to be transferred to quarantined cows. As of August 2017, Ramaphosa had 100 Ankole breeding cows at his Ntaba Nyoni farm in Mpumalanga. That year, he co-wrote a book about the breed, Cattle of the Ages: Stories, and Portraits of the Ankole Cattle of Southern Africa. Public service His resignation from politics notwithstanding, Ramaphosa occasionally accepted positions in the public eye, both abroad and in South Africa. He became the first Vice Chairman of the Commonwealth Business Council, and, in 1998, the Chairman of South Africa's BEE Commission. In 2000, he was appointed to the Independent International Commission on Decommissioning as an arms inspector, responsible for supervising the decommissioning of Irish Republican Army armaments in Northern Ireland. And, in April 2010, he was appointed by President Jacob Zuma to the National Planning Commission, where he served as Deputy Chairperson to Minister in the Presidency Trevor Manuel. In the 2007–2008 Kenyan crisis, which followed the disputed re-election of President Mwai Kibaki in December 2007, Ramaphosa was unanimously chosen by Kofi Annan's mediation team to be the chief mediator in charge of long-term talks. However, Kibaki's government protested Ramaphosa's involvement, saying that he had business links with Kibaki's opponent Raila Odinga. According to Ramaphosa, Odinga had visited him in 2007, but he did not have any "special interest" that would lead him to favour one side or the other; however, he said that he could not be an effective mediator without "the trust
