On Thursday Apple filed its 10-K filing (http://macte.ch/7FxgL) with the U.S. Securities and Exchange Commission (SEC) for the 2012 fiscal year. Here are some tidbits from the filing:

° Apple spent US$3.4 billion on research and development (R&D) in 2012. That's an increase of $1 billion from 2011.

° Apple has approximately 72,800 full-time employees and an additional 3,300 part-timers and contractors. About 42,400 of the total full-time equivalent employees worked in the retail segment.

° Apple's retail stores account for 12% of the company's net sales. That's down from 13% in 2011. Apple plans to open another 30-35 retail stores in 2013.

° Apple increased its number of retail stores from 357 at the end of fiscal 2011 to 390 stores at the end of fiscal 2012. The company earned an average of $51.5 million per store, compared to $43.3 million in 2011.

° Unlike last year, when Apple said it had no plans to pay a dividend,
the company now "expects to pay quarterly dividends in the future."

° Apple's capital expenditures for 2012 was $10.3 billion, with retail accounting for $856 million, while $9.5 billion went to "other" expenses including product tooling and manufacturing. For the 2013 fiscal year, the company said it anticipates spending to drop to $10 billion.
