ASUS CFO David Chang on Friday commented that his company and others might face a ripple effect from Acer's European overstock writeoff. Depending on what systems had gone unsold, they could either have only a minimal effect or create shockwaves, he said. If the unsold inventory represents current PCs using Sandy Bridge-based Intel processors, the writeoff could amount to price dumping as the systems hit stores at steep discounts and temporarily boost Acer's European market share while squeezing out ASUS and others.
