Overall December 2013 performance was quite stable compared to November 2013 in terms of volume, ASP and shipment mix. We continued to see strong installation activities in various regions. Pricing also started to show some strength exit the year.
As worldwide demand continues to grow with limited supply expansion, overall pricing has been moving up throughout the supply chain. We remain optimistic about the structural turn around and expect to see profitable growth with our leading industry position.
