Apple Computer Inc. still hasn’t filed its annual report with the Securities and Exchange Commission, saying that it is still investigating the backdating of stock options. Apple needs to restate some historical financial statements to record additional compensation expense, and says it can’t file its 10-K for the fiscal year ended September 30 until the investigation is complete.

According to Apple, the problem with backdating stock options occurred between 1997 and 2002, and CEO and founder Steve Jobs was aware of some of it.
