Adobe Systems is due to announce its third-quarter financial results in a webcast at 2PM Pacific Time (10PM, UK time) tomorrow, Thursday September 13.

In light of yesterday's terrorist attacks on New York and Washington - and the subsequent hold in trading on Wall Street - it is not yet clear if the announcement will take place as scheduled.

Adobe officials told Macworld this morning that its San Jose, California head-office was yesterday evacuated as a security precaution. San Jose also hosts two twin towers which were considered potential terrorist targets. The Adobe offices are a few blocks away from San Jose international airport.

The company has confirmed that no Adobe employees were on board the hijacked aircraft, nor injured in the attacks on New York or the Pentagon.

Before the crisis caused the markets to close yesterday, Adobe shares rose 2.37 per cent to close at $32.87.
