10-K

A common report required of all publicly traded companies is the 10-K. This is an annual report that all public companies in the US have to file with the US Securities and Exchange Commission (SEC).

Figure 2 shows Apple's 10-K's table of contents, and illustrates common types of data used. Note how much of it is quantitative based (Item 6 for example,) however other data, such as leadership biographies (Item 10), also provides context.
