The bio/pharmaceutical industry is under continued pressure to accelerate the development and marketing of new drugs, while reducing operating costs and improving financial performance. We believe that the RPS approach of providing innovative, integrated clinical development solutions that leverage the existing infrastructure and investments of bio/pharmaceutical companies addresses these challenges and provide the opportunity to significantly reduce overall costs while improving the quality and speed of drug development. Our strong financial performance and continued growth reflect the expanding acceptance of our business model by the bio/pharmaceutical industry."
