They're up 2% for the first nine months, helped by better economic conditions in many of its emerging markets.Lager volumes jumped 12% both in Africa, where price cuts in Zambia led to a 38% surge, and in Asia, led by a 16% increase in China against weak comparatives - heavy snow subdued last year's number. India disappointed though as regulatory issues continued to hurt volumes.Bible, 73, used to be chief executive of Altria Group, the parent company of the US tobacco firm Philip Morris. He was also chairman of the board of the food giant Kraft.Top Director BuysSABMiller (SAB) Director name: Mr Geoffrey BibleAmount purchased: 55,000 @ 2,211.06p Value: £1,216,083Polo Resources Ltd.
