Currently, several companies voluntarily submit financial statements in XBRL format. For this assignment, go to the SEC website at www.sec.gov. Once there, search for a company and click the link that says "Interactive Data" in the report list and follow the link. Now follow the "Interactive Data Viewers" link, then "Interactive Financial Reports." Download the income statement and balance sheet from the annual report for the company you chose. Using these reports, calculate the financial ratios for the company from the data available, typically two or three years.

Do you notice any changes in these ratios that might indicate further investigation?
