On August 18, 2011, then-CEO of HP Leo Apotheker announced plans for a partial or full spinoff of the Personal Systems Group. The PC unit had the lowest profit margin although it accounted for nearly a third of HP's overall revenues in 2010. HP was still selling more PCs than any other vendor, shipping 14.9 million PCs in the second quarter of 2011 (17.5% of the market according to Gartner), while Dell and Lenovo were tied for second place, each with more than a 12% share of the market and shipments of over 10 million units. However, the announcement of the PC spinoff (concurrent with the discontinuation of WebOS, and the purchase of Autonomy Corp. for $10 billion) was poorly received by the market, and after Apotheker's ouster, plans for a divestiture were cancelled. In March 2012, the printing and imaging division was merged into the PC unit. In October 2012, according to Gartner, Lenovo took the lead as the number one PC manufacturer from HP, while IDC ranked Lenovo just right behind HP. In Q2 2013, Forbes reported that Lenovo ranked ahead of HP as the world's number-one PC supplier.
