The average stock prices for each of the four years shown in Exhibit 1 were as follows: 1998 111/4 = 27.75 1999 163/4 = 40.75 2000 281/2 = 140.5 2001 91/2 = 45.5 a. compute the price/earnings ratio for each year. That is‚ take the stock price shown above and divide by net income per common stock-dilution from exhibit 1. 2001 (3‚417)/$ 0.27 = 12‚655.5 2000 (3‚379)/$0 .55 = 6‚143.63 1999 (3‚282)/$ 0.31 = 10‚587.09 1998 (3‚180)/$ 0.24 = 13‚250.00 b.
