But Jobs offered no new details on what the investigation, which Apple launched at the end of June, has found. Moreover, he did not respond to questions about the investigation shouted at him while he milled about with guests after the media event.

Specifically, Jobs declined to comment on whether the company backdated its options or what the "irregularities" were, or whether he personally was responsible for the "irregularities."

Apple has previously said that it found numerous problems with its past grants, including at least one given to Jobs. As a result, the company has delayed filing its latest quarterly report and has warned that it plans to restate reports from previous quarters and years.

Some analysts and investors are worried that Jobs could be implicated in the trouble and, if so, could be forced from the company.

Apple last updated investors on its probe last month when it filed a document with the SEC warning that it would not post its third-quarter report on time.

Apple spokesman Steve Dowling also declined to comment further on the status of the company's options probe.
