Profitability refers to a company's ability to obtain  profits and positive cash flows and to its ability to obtain an adequate return on invested capital or a company's ability to give an adequate return relative to resources devoted to company operations. It is the key to a company's long- run survival. Performance and profitability of a company often are evaluated using the financial information given by a firm's annual report in comparison with other firms in the similar industry. Ratios are useful in this assessment.

Required:

1. Show the incomes - gross, operating, and net - and measure their margin ratios for your company for the last three years.

2. What do your calculations indicate about the firm? What are the ratio trends?

3. Calculate the return on assets, return on equity, cash return on assets, cash flow margin, book value per common share, and effective tax rate for your company for the last three years.
