SouthernEra to join benchmark S&P/TSX index

CANADIAN platinum and diamond producer SouthernEra is to be admitted to Toronto's benchmark S&P/TSX Composite index in the first major purge since Standard & Poor's took over management of the index earlier this year.

S&P, which replaced the old Toronto Stock Exchange 300 index with the S&P/TSX after taking it over on May 1, said it would drop 30 companies from the index after the market closes on Friday
