other server applications as a result of growth in PC and server hardware shipments. The worldwide PC shipment growth rate from all sources was estimated at 13% and the Windows server shipment was estimated at 18% in fiscal year 2004 as compared to fiscal year 2003. The net impact of foreign exchange rates on revenue was positive in fiscal year 2004 due to a relative strengthening of most foreign currencies versus the U.S. dollar. This resulted in approximately $1.10 billion growth in total revenue. Revenue growth in fiscal year 2003 was driven primarily by multi-year licensing that occurred before the Licensing 6.0 transition date in the first quarter of fiscal year 2003. The fiscal year 2003 revenue growth also reflected a $933 million or 13% increase associated with OEM licensing of Windows operating systems and a $309 million or 23% increase in revenue from Xbox video game consoles. 

For fiscal year 2005, the operating income increase was driven by a decline in stock-based compensation expense; increased revenue in Server and Tools, Client and Information Worker, which have higher gross margins as compared to other segments; and a reduction in legal costs associated with major litigation. In addition, strong sales of Halo 2 reduced the overall operating loss for the Home and Entertainment segment for fiscal year 2005. The $3.29 billion decrease in stock-based compensation expense was partially offset by increased operating expenses of $562 million related to increased salary and benefits for new and existing headcount. General and administrative expenses related to major litigation declined in fiscal year 2005 due to the $2.53 billion of charges related to the settlement of Sun Microsystems litigation and the fine imposed by the European Commission in fiscal year 2004. This effect was partially offset by legal expenses of $2.08 billion related to settlements with IBM, Novell, Gateway, and end-user class action plaintiffs to resolve antitrust issues and other matters. In fiscal year 2004, the operating income decline was caused primarily by $2.53 billion of legal charges and $2.21 billion of stock-based compensation expense related to our employee stock option transfer program, mainly offset by an increase in revenue. In fiscal year 2003, the growth in operating income reflected an increase in revenue, partially offset by an increase in operating expenses related to employee and related costs associated with headcount and increased legal settlement expenses, primarily the Time Warner settlement charge of $750 million.





In fiscal year 2004, we implemented changes in employee compensation whereby employees are granted stock awards rather than stock options. We also completed an employee stock option transfer program in the second quarter of fiscal year 2004 in which employees could elect to transfer all of their vested and unvested stock options with a strike price of $33 or higher to JPMorgan. The unvested options that were transferred to JPMorgan became vested upon the transfer. A total of 345 million of the 621 million eligible options were transferred, which resulted in additional stock-based compensation expense of $2.21 billion
