In Principle, few South Africans disagree with B. In practice, there has been much grumbling over the way B is clearly intrusive, setting quotas and timetables in terms of black ownership, employment, and affirmative action procurement. South Africans can firms, which are predominantly owned and managed by whites, are compelled to sell a substantial percentage (25% to 50%) of their equity to black-owned businesses and investors often at discounted prices. A number of leading South Africans firms listed on the New York Stock Exchange, such as AngloGold, SAPPI, SASOL, and Telkom, have disclosed B as a risk to shareholders, because these firms cannot guarantee that B transactions would take place at fair market price.
