* Some numbers in a chart accompanying the April 15 Pensions & Investments story on company stock performance were incorrect. General Electric Co.'s 1996 stock price should have been $14.78. Figures for annualized change of the stock prices that appeared in the chart were for a 10-year period, making them roughly half what they should have been over the five-year period cited in the chart. For instance, Procter & Gamble's annualized change should have been 8.7%, Boeing's should have been -6.1%, and so on. For comparison, the five-year annualized change for the S&P 500 should have been 8.7%.
