Apple is forecasting a 73 percent growth in capital expenditures in its 2012 fiscal year that should bring the tally up to $8 billion, says UBS analyst Maynard Um, who has examined an Apple 10-K filing made public last week. The $3.4 billion jump is believed to be related to its two major upcoming building projects. The first is a solar farm for its Maiden, North Carolina datacenter, while the second is the planned "spaceship" campus in Cupertino, California.
