Publicly-traded companies are obliged to file annual reports with the U.S. Securities and Exchange Commision. Most are dry, recitations of a firm’s plans and projections, but sometimes they give insight into an otherwise tight-lipped organization, such as Apple. The Cupertino, Calif. company, riding high from its recent iPhone 4 and iPad successes, has increased its staff by a third, hiked its advertising budget and isn’t expecting any big acquisitions in 2011.
Apple has 26,500 employees, a third more than the 10,000 reported in 2009. The increase may be linked to the company’s retail expansion. The iPad maker has 317 retail stores, up from 273 a year ago. The company told federal regulators it plans to open 50 more retail locations in 2011.
