SABMiller Plc (SAB)’s Sechaba Breweries Ltd. (SCHB), Botswana’s biggest beermaker, said full-year profit rose 10 percent to 240 million pula compared with a year earlier.

The improvement in net income for the year through March was due to a change in the calculation of a 40 percent state tax on alcohol, the company said in a statement published in the Gaborone-based Mmegi newspaper today. It declared a dividend of 24 thebe a share.

Clear beer sales declined 0.2 percent compared with a year earlier and sales of sorghum beer fell 1.2 percent, the company said.
