Margin decline: "Until recently, our gross profit generally experienced growth in line with increases in our revenue. However, more recently, our gross margin has been decreasing from 67.0% in 2006, to 65.1% in 2007 and 47.9% in 2008. Our gross profit and gross margin are affected by a variety of factors, including average selling prices of our products, our product application mix, prices of wafers, excess and obsolete inventory, pricing by competitors, changes in production yields, and percentage of sales conducted through distributors."
