1. Go to Market Insight (www.mhhe.com/edumarketinsight). Find the net capital expenditures, capital expenditures less sales of plant and equipment, and total sales for General Motors (GM) and Microsoft (MSFT). What were the ratios of net capital expenditure to sales for the last 3 years for both companies? What were the sales and net capital expenditures relative to total assets? What might explain the variation in these ratios for these two large corporations? Did the company make an investment or disinvestment in working capital in each of the 3 years?
