Apple will reveal its fourth quarter and full financial year 2006 results on 18 October.

The company is likely to reflect on another bumper year for sales, with successive quarters of high achievement marking 2006.

However, the year has had its challenges, not least the ongoing investigation into stock options irregularities in Cupertino.

According to the last three financial statements, Apple has sold 3,693,000 Macs and 30,660,000 iPods so far this year.

Speaking in July, Apple chief financial officer Peter Oppenheimer predicted fourth quarter revenue of about $4.5 to $4.6 billion.
