The income statement has some limitations since it reflects accounting principles. For example, a company's depreciation expense is based on the cost of the assets it has acquired and is using in its business. The resulting depreciation expense may not be a good indicator of the economic value of the asset being used up. To illustrate this point let's assume that a company's buildings and equipment have been fully depreciated and therefore there will be no depreciation expense for those buildings and equipment on its income statement. Is zero expense a good indicator of the cost of using those buildings and equipment? Compare that situation to a company with new buildings and equipment where there will be large amounts of depreciation expense.
The remainder of our explanation of financial ratios and financial statement analysis will use information from the following income statement:

Financial statement analysis includes a technique known as vertical analysis. Vertical analysis results in common-size financial statements. A common-size income statement presents all of the income statement amounts as a percentage of net sales. Below is Example Corporation's common-size income statement after each item from the income statement above was divided by the net sales of $500,000:
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The percentages shown for Example Corporation can be compared to other companies and to the industry averages. Industry averages can be obtained from trade associations, bankers, and library reference desks. If a company competes with a company whose stock is publicly traded, another source of information is that company's "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in its annual report to stockholders. Generally the annual report as well as reports to the Securities and Exchange Commission are available on the company's website.
