Once a year, the Securities and Exchange Commission (SEC) requires every company of a certain size ($10m in assets) to file an annual report, laying out a comprehensive summary of its financial performance. That report is known as the Form 10-K.

There are a lot of interesting tidbits in Apple’s 10-K, including patent filings, dependencies, and lots of discussion of risks in the marketplace. But if you don’t feel like digging through all the cruft, Chris O’Brien, writing for Venture Beat, did a nice job of laying out some of the highlights.
