Other Intel Architecture Operating Segments

The revenue and operating income (loss) for the other Intel architecture operating segments, including the Intelligent Systems Group, Intel Mobile Communications, the Netbook Group, the Tablet Group, the Phone Group, and the Service Provider Group for the three years ended December 29, 2012 were as follows:

(In Millions) 2012 2011 2010
Net revenue $4,378  $5,005  $3,055
Operating income (loss) $(1,377) $(577) $270

Net revenue for the Other IA operating segments decreased by $627 million, or 13%, in 2012 compared to 2011. The decrease was primarily due to lower IMC average selling prices and lower netbook platform volume. To a lesser extent, lower netbook platform average selling prices contributed to the decrease. These decreases were partially offset by higher ISG platform average selling prices.

Operating results for the Other IA operating segments decreased by $800 million from an operating loss of $577 million in 2011 to an operating loss of $1.4 billion in 2012. The decline in operating results was primarily due to lower netbook revenue and higher operating expenses in the Other IA operating segments. Additionally, lower IMC revenue was largely offset by lower IMC unit cost.

Net revenue for the Other IA operating segments increased by $2.0 billion, or 64%, in 2011 compared to 2010. The increase was primarily due to IMC revenue, an operating segment formed from the acquisition of the WLS business of Infineon in the first quarter of 2011. To a lesser extent, higher ISG platform unit sales also contributed to the increase. These increases were partially offset by lower netbook platform unit sales.

Operating results for the Other IA operating segments decreased by $847 million from an operating income of $270 million in 2010 to an operating loss of $577 million in 2011. The decline in operating results was primarily due to higher operating expenses within each of the Other IA operating segments, partially offset by higher revenue.
