1. Prepare a December 31, 2011 classified balance sheet for Amazon.com. Include the correct amount for accounts receivable.

2. Compute the companys working capital, current ratio, and quick ratio. Compute the quick ratio as (current assets inventory) divided by current liabilities.

3. Comment on the companys current and quick ratios. In 2010, the current ratio was 1.33 and the quick ratio was 1.02.
