from licensing our Office System products. Revenue growth depends on the ability to add value to the core Office product set and expand our product offerings in other information worker areas such as document lifecycle management, collaboration, and business intelligence.



Beginning in fiscal year 2005, the Small and Mid-Market Solutions & Partners (SMS&P) organization, which was historically part of Information Worker, was re-aligned in Microsoft Business Solutions. As a result of this change, Information Worker results have been restated to reflect the reclassification of the SMS&P organization to Microsoft Business Solutions. The results for previous periods have also been restated due to the reclassification of Professional product support services from Information Worker into Server and Tools. 

Information Worker revenue increased in fiscal year 2005 primarily due to a 3% or $269 million increase in volume licensing, retail packaged product, and pre-installed versions of Office in Japan, a 6% or $91 million increase in OEM revenue, and the impact of foreign currency exchange rates, partially offset by reduced Upgrade Advantage earned revenue. Changes in foreign currency exchange rates accounted for approximately $367 million or three percentage points of the revenue growth for fiscal year 2005 as compared to the previous fiscal year, offset by a $663 million decline in Upgrade Advantage earned revenue. Revenue growth for fiscal year 2004 from volume licensing, retail packaged product and pre-installed versions of Office in Japan was 15% in aggregate. This increase was driven by recognition of unearned revenue primarily from a large increase in multi-year licenses signed previous to the transition to our Licensing 6.0 programs and approximately $110 million related to the launch of Office 2003. OEM licensing revenue grew 29% or $325 million. Foreign currency exchange rates provided approximately $485 million or 5% of total Information Worker revenue growth. 

Information Worker operating income growth for fiscal year 2005 was primarily due to the revenue growth and a decrease in stock-based compensation expense. Operating expenses were also impacted by a reduction in marketing campaign costs from the previous period associated with the launch of Office 2003. This decline was offset by an increase in headcount-related costs from increased hiring and increases in salary and benefits. Information Worker operating income in fiscal year 2004 increased from the previous year primarily due to growth in revenue, partially offset by an increase in operating expenses, primarily related to $351 million of stock-based compensation expense from the employee stock option transfer program in the second quarter of fiscal year 2004 and higher sales and marketing expenses. 

The revenue growth rate for Information Worker is expected to be higher in fiscal year 2006 than fiscal year 2005. We expect sustained momentum in our OEM and multi-year licensing offerings and increased purchasing of Office System 2003 as enterprises complete their product evaluations. We expect to see slowing revenue from packaged product late in the year as we approach the next
