1) Choose a large or midsized (market cap over $5 billion) public company.  Get the latest financial report (10-Q or 10-K) for your chosen company and compute a ratio which is significantly different from same ratio for your chosen company last year (or quarter), or considerably different from same ratio for a very similar competitor. Describe what ratio you chose and how you computed it for your company's most recent financials and for your company's previous financials for its competitor. (include data sources). Choose a important and interesting ratio, not first one on the list or the easiest one to work with.

Read up on company (in financial reports, business press, etc) and describe of what difference between ratio and comparative ratio (same ratio for previous period or for competitor) you selected means and one major reason why you believe there is such important difference in two.
