We are challenging ourselves everyday to produce an increasing volume of more affordable and higher-purity polysilicon, the key raw material required for the vast majority of today's solar power generation, to meet a huge market demand. To accomplish this, we're building out economies of scale through our cost-efficient, China-based manufacturing facilities, exploring sources of lower-cost raw materials, employing an experienced team of scientists and engineers and investing strategically in research and development.
In addition to our successful polysilicon production, we engage in solar wafer sales to some of the industry's leading solar companies. At present, our wafers are produced through tolling arrangements with third-party manufacturers who create high-quality wafers using our polysilicon.
Our culture of execution stems from a management team with proven project execution capabilities in polysilicon production build-out. In fact, within 15 months of breaking ground, we completed construction of our Xuzhou Phase I production facilities in Xuzhou, Jiangsu province and shipped our first batch of polysilicon. Upon completion of our planned expansion to 21,000 MT of annual polysilicon production capacity by the end of 2010, we believe we will be one of the largest polysilicon and wafer producers in the world in terms of production capacity.
